ELECTRONIC HOOKAH HEATER

TECHNICAL FIELD

[0001]The present disclosure relates to the technical field of electronic hookahs, and in particular, to an electronic hookah heater.

BACKGROUND

[0002]Arab hookah is a culturally distinctive smoking way. A specially designed hookah device is used to filter, by using water or another liquid, smoke generated after a tobacco product is atomized, which provides a smoker with a relatively soft and interesting smoking experience. However, the traditional Arabic hookah has several significant technical issues during use, which affect its convenience and safety.

[0003]Firstly, the traditional Arab hookah heats a tobacco product by burning charcoal. In this process, the charcoal releases carbon monoxide and a large amount of ash powder, which not only pollutes a smoking environment, but may also pose a potential threat to the health of the smoker. Carbon monoxide is a colorless, odorless, and non-irritating toxic gas with a strong binding ability to hemoglobin, which can easily cause poisoning.

[0004]Secondly, in the mode for heating the tobacco product by using the charcoal, a user needs to add or remove charcoal frequently, to maintain an optimal heating temperature of the tobacco product. This process is tedious, and it is difficult to precisely control a heating temperature, which affects a taste and quality of the smoke. In addition, frequent manual operations also increase inconvenience and safety hazards during use. Therefore, it is necessary to make improvements.

SUMMARY

[0005]The present disclosure aims to provide an electronic hookah heater to address the shortcomings of the existing technology. A first heating module can uniformly and quickly heat tobacco paste or tobacco shreds in a tobacco pipe through a heat conducting base, to generate rich smoke. A ventilation valve is opened, and external air enters a ventilation channel inside an air intake amount control member through a ventilation channel for primary heat exchange to increase a temperature, and then passes through an air guide channel for secondary heat exchange to increase the temperature. After the two heat exchanges, the air finally enters the tobacco pipe and is mixed with smoke, thus achieving effects of facilitating a user to inhale the smoke, controlling a concentration of the smoke, and ensuring a consistent taste of the smoke. Compared with a traditional charcoal heating mode, stable heating and smoke generation can be achieved through simple settings and adjustments. A taste of smoke produced by tobacco paste or tobacco shreds is consistent, which greatly simplifies a use process and improves convenience and safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043]The present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0044]As shown in FIG. 1 to FIG. 11, an electronic hookah heater of the present disclosure includes a heat conduction base 1, a sealing cover 2, a first heating module 3, and an air intake amount control member 4.

[0045]The first heating module 3 is an electric heating module, such as a resistive heating element, an electric heating tube, positive temperature coefficient (PTC) heating element, or a far-infrared heating element. After being powered on, the first heating module 3 generates heat to heat e-liquid or tobacco shreds in a tobacco pipe. Compared with a mode for heating a tobacco product by relying on charcoal burning, the heating mode using the first heating module 3 improves heating efficiency and ensures stable production of smoke.

[0046]The heat conduction base 1 covers an opening in a top of the tobacco pipe. A heating cavity 11 for accommodating the first heating module 3 is arranged inside the heat conduction base 1. Through the heating cavity 11, it is convenient to fix the first heating module 3. The design of the heating cavity 11 also protects the first heating module 3 from external interference, which prolongs the service life of the first heating module 3.

[0047]The sealing cover 2 is detachably connected to the heat conduction base 1. The heating cavity 11 is located between the sealing cover 2 and the heat conduction base 1 and maintains a sealed state. Specifically, the sealing cover 2 and the heat conduction base 1 are connected in a detachable manner (such as, through a thread and a buckle) to form a sealed structure. It is convenient for a user to remove the sealing cover 2 to clean or repair the heating cavity 11, or replace the first heating module 3, thereby reducing the maintenance difficulty and costs.

[0048]In some embodiments, an air guide channel 12 that allows external air to enter the tobacco pipe is arranged on the heat conduction base 1. In some other embodiments, air guide channels 12 that allow external air to enter the tobacco pipe are arranged on both the sealing cover 2 and the heat conduction base 1 in a penetrating manner. The air guide channel 12 penetrates through the heat conduction base 1 or the sealing cover 2 and the heat conduction base 1, so that the setting of the air guide channel 12 is flexible and is easily implemented.

[0049]The air intake amount control member 4 covers an upper part of the sealing cover 2 and is provided with a ventilation channel 41 communicated to the air guide channel 12. A ventilation valve 42 is arranged at a joint between the ventilation channel 41 and an outside. Specifically, the air intake volume control member 4 is of a hollow structure, such as a cylinder, and the ventilation channel 41 is arranged inside the air intake volume control member 4.

[0050]By using the heating mode using the first heating module 3, instead of the traditional charcoal combustion mode, the present disclosure effectively avoids release of carbon monoxide and ash powder during combustion, thereby reducing air pollution and a potential threat to the health of a smoker, making an Arab hookah more environmentally friendly and safer.

[0051]Through the first heating module 3 and the air intake volume control member 4, precise temperature control and air flow regulation can be achieved.

[0052]By intelligently controlling the power of the first heating module 3, the first heating module 3 can uniformly and quickly heat tobacco paste or tobacco shreds inside the tobacco pipe through the heat conduction base 1, to generate rich smoke. It can ensure that a tobacco product is heated at an optimal temperature, thereby producing smoke with a better taste and higher quality. This improves the comfort level and quality of smoking.

[0053]Cooperation of the air intake volume control member 4, the ventilation channel 41, the ventilation valve 42, and the air guide channel 12 can achieve precise air flow regulation, making it easier for a user to inhale smoke and ensuring that the external air can smoothly enter the tobacco pipe. This means that the external air and the smoke can be fully mixed, making it easier for the user to inhale the smoke and adjust the taste of the smoke.

[0054]Furthermore, the air intake volume control member 4 covers the upper part of the sealing cover 2, so that temperatures inside the ventilation channel 41 and the air guide channel 12 are greater than an external temperature. In practical use, external cold air enters the ventilation channel 41 for primary heat exchange for heating, and the external air after the primary heating is then subjected to secondary heat exchange through the air guide channel 12, which means that the external air that has been heated twice may reach a preset temperature before entering the tobacco pipe, which ensures the stability of the temperature inside the tobacco pipe. In other words, for a situation in which the external cold air directly enters the tobacco pipe, causing heat loss inside the tobacco pipe and easily causing an inconsistent taste, the present disclosure gradually heats the external cold air through circulation, so that the smoke produced by the tobacco paste or the smoke produced by the tobacco shreds may keep a consistent taste, which enhances the feeling of a user. Meanwhile, by using the mode for twice heating, power required by once heating can be reduced.

[0055]During use, a first heating module 3 can uniformly and quickly heat the tobacco paste or the tobacco shreds inside the tobacco pipe through the heat conducting base 1, to generate rich smoke. The ventilation valve 42 is opened, and the external air enters the air intake volume control member 4 through the ventilation channel 41 for primary heat exchange. After the temperature of the external air is increased, the external air then passes through the air guide channel 12 for secondary heat exchange to increase the temperature again. After the two heat exchanges, the air finally enters the tobacco pipe and is mixed with smoke, thus achieving effects of facilitating a user to inhale the smoke, controlling a concentration of the smoke, and ensuring a consistent taste of the smoke. Compared with a traditional charcoal heating mode, stable heating and smoke generation can be achieved through simple settings and adjustments. The taste of the smoke produced by the tobacco paste or the tobacco shreds is consistent, which greatly simplifies a use process and improves convenience and safety. A heating temperature can be precisely controlled to ensure the taste and quality of the smoke, thus avoiding frequent manual operations and improving the convenience and the safety in the use process.

[0056]As shown in FIG. 4, the heat conduction base 1 or the sealing cover 2 is provided with an extension ring 13, and the extension ring 13 presses against the top of the tobacco pipe.

[0057]Since the extension ring 13 is arranged on the heat conduction base 1 or the sealing cover 2 in a radial direction, the extension ring 13 presses against the top of the tobacco pipe, which improves the stability of connection between the heat conduction base 1, the sealing cover 2, and the tobacco pipe. This design helps prevent looseness or falling of the electronic hookah heater due to an external force such as drop and collision during use, thus improving the durability and reliability of the electronic hookah heater.

[0058]The pressing between the extension ring 13 and the top of the tobacco pipe also plays a sealing role, which helps prevent smoke, heat, or e-liquid from leaking from a joint. It maintains the stability of an environment inside the heating cavity 11, prevents external impurities from entering the heating cavity, and improve the overall performance of the electronic hookah heater.

[0059]As shown in FIG. 5, in some embodiments, a first heat conduction and insulation layer 5 is arranged on the first heating module 3 of this embodiment. In some embodiments, first heat conduction and insulation layers 5 are arranged on the sealing cover 2 and the heating cavity 11 of the heat conduction base 1. Effective conduction of heat and safe use are ensured through the first heat conduction and insulation layer 5.

[0060]Preferably, the first heat conduction and insulation layer 5 is made of insulation ceramic, which can achieve insulation, without affecting heat transfer. In other embodiments, the first heat conduction and insulation layer 5 can be made of a mica sheet, quartz, or a ceramic material (aluminum oxide and aluminum nitride).

[0061]Preferably, the first heat conduction and insulation layer 5 includes two first insulation layers 51 and a first heat conduction layer 52. The two first insulation layers 51 are respectively arranged at upper and lower ends of the first heating module 3. The first heat conduction layer 52 is arranged on one side of the first heating module 3 close to the tobacco pipe, namely, the first heat conduction layer 52, the first insulation layer 51, the first heating module 3, and the first insulation layer 51 are arranged in sequence.

[0062]The arrangement of the first insulation layers 51 effectively isolates the first heating module 3 from an external environment, thereby preventing direct conduction of current to a user or another component that may be in contact, and greatly improving the safety of the electronic hookah heater.

[0063]The first heat conduction layer 52 is located between the first heating module 3 and the tobacco pipe, which can quickly transfer heat generated by the electronic hookah heater to the tobacco pipe, thereby improving the heat transfer efficiency and making heating more uniform and quicker.

[0064]Preferably, the first insulation layers 51 are made of insulation ceramic, which can achieve insulation, without affecting heat transfer. In other embodiments, the first insulation layers 51 may be made of a mica sheet, quartz, or a ceramic material.

[0065]The first heat conduction layer 52 is made of heat conduction silicone grease. In other embodiments, the first heat conduction layer 52 can also be made of a ceramic material, a carbon-based material, a polymer composite material, and the like, to ensure uniform heat transfer of the first heat conduction layer 52.

[0066]As shown in FIG. 6, in another embodiment, the first heat conduction and insulation layer 5 includes two first metal oxide layers 53. The two first metal oxide layers 53 are respectively arranged on an inner wall of the heating cavity 11 and an inner side of the sealing cover 2.

[0067]The first metal oxide layers 53 have good heat conductivity and can quickly transfer heat from a heat source to a region that needs to be heated, thus improving the heating efficiency.

[0068]As insulation layers, the first metal oxide layers 53 can effectively isolate current and prevent the current from directly passing through the heating cavity 11 or the sealing cover 2, which ensures the electrical safety of the electronic hookah heater.

[0069]Specifically, each first metal oxide layer 53 can be an aluminum oxide layer, a titanium oxide layer, a zinc oxide layer, or aluminum nitride. Preferably, the first metal oxide layers 53 of this embodiment are the aluminum oxide layers.

[0070]As shown in FIG. 5, the sealing cover 2 of this embodiment is provided with a thermal insulation layer 21. Specifically, in some embodiments, the thermal insulation layer 21 is arranged inside the sealing cover 2. In some embodiments, the thermal insulation layer 21 is arranged at an upper end of the sealing cover 2. In some embodiments, the thermal insulation layer 21 is arranged at a lower end of the sealing cover 2.

[0071]The thermal insulation layer 21 can effectively isolate the heat of the heating cavity 11, which ensures that the heat is conducted in a predetermined direction, thereby improving the heat utilization efficiency and reducing unnecessary heat loss.

[0072]On the other hand, the temperature of the sealing cover 2 is significantly reduced by the arrangement of the thermal insulation layer 21. This not only allows a user to safely and conveniently pick up the electronic hookah heater through the sealing cover 2, but also reduces a potential risk of injury caused by accidentally touching the sealing cover 2 with a high temperature.

[0073]Preferably, the thermal insulation layer 21 is made of insulation ceramic, which can achieve insulation, without affecting heat transfer. In other embodiments, the thermal insulation layer 21 can also be made of a mica sheet, quartz, or a ceramic material.

[0074]As shown in FIG. 4, one end of the sealing cover 2 facing the heat conduction base 1 is provided with a first limiting portion 22 and a second limiting portion 23.

[0075]The first limiting portion 22 presses against the top of the heat conduction base 1.

[0076]The second limiting portion 23 presses against the inner wall of the heating cavity 11.

[0077]By the pressing between the first limiting portion 22 and the top of the heat conduction base 1, it ensures that the sealing cover 2 is stably mounted on the heat conduction base 1, which prevents shaking or falling of the sealing cover 2 during use, and improving the stability of the overall structure.

[0078]The arrangement of the first limiting portion 22 and the second limiting portion 23 provides a clear mounting position for the sealing cover 2, which ensures accurate alignment between the sealing cover 2 and the heat conduction base 1, and avoids a mounting error.

[0079]The pressing between the second limiting portion 23 and the inner wall of the heating cavity 11 may further play a sealing role, which prevents leakage of the heat inside the heating cavity 11 and improves the heating efficiency and the use safety.

[0080]As shown in FIG. 4, FIG. 7, and FIG. 8, a heat conductor 6 is arranged in the ventilation channel 41 of this embodiment. The heat conductor 6 is arranged at the sealing cover 2 and is configured to conduct heat generated by the first heating module 3. The heat conductor 6 is a heat sink, which is usually made of metal and has a large surface area to accelerate heat dissipation. By the arrangement of the heat conductor 6, the heat generated by the first heating module 3 can be more effectively diffused into the ventilation channel 41, which allows the external cold air to enter the ventilation channel 41 for heat exchange.

[0081]As shown in FIG. 8, FIG. 9, and FIG. 10, the ventilation channel 41 of this embodiment is provided with a second heating module 7. The second heating module 7 is configured to increase the temperature inside the ventilation channel 41. In some embodiments, the second heating module 7 is fixed to the heat conductor 6. In some embodiments, the second heating module 7 is fixed to the sealing cover 2. By using the second heating module 7, the heat conductor 6 is heated up faster, thereby increasing the temperature inside the ventilation channel 41 and transferring the heat more uniformly into the ventilation channel 41, thereby improving the heating efficiency and the heat utilization rate, and enhancing a preheating effect on the external cold air.

[0082]The second heating module 7 can be a resistive heating element, an electric heating tube, a PTC heating element, or a far-infrared heating element. In this embodiment, the second heating module 7 being the resistive heating element is taken as an example.

[0083]As shown in FIG. 10, specifically, the second heating module 7 is further provided with a shell 71. The second heating module 7 is sealed by the shell 71 to prevent external interference. The shell 71 can also change a flowing direction of the air in the ventilation channel 41, thereby prolonging time for the air to flow in the ventilation channel 41, and ensuring that the air undergoes sufficient heat exchange in the ventilation channel 41 to increase the temperature of the air.

[0084]As shown in FIG. 1 and FIG. 7, the electronic hookah heater of this embodiment further includes a control module, a display 9, and a sensor 72. The control module is a microprocessor or a microcontroller. The control module is connected to an external power supply and is responsible for providing stable power supplying to the hookah heater. The sensor 72 is a temperature air flow sensor, such as a thermosensitive air flow sensor or a hot film air flow sensor.

[0085]The display 9 is configured to display information and output a sound, which is convenient for reminding or warning a user and attracting the attention of the user, thereby facilitating better use of the electronic hookah heater of the present disclosure by the user. Specifically, the display 9 is fixed to the air intake volume control member 4.

[0086]The sensor 72 is configured to detect an air flow volume and air temperature inside the air guide channel 12, and a temperature of the heat conduction base 1.

[0087]The first heating module 3, the second heating module 7, the sensor 72, and the display 9 are all electrically connected to the control module. Key parameters are detected in real time through the sensor, such as the temperature of the thermal base and the air flow volume and temperature in the air guide channel, and are fed back to the control module. Precise control and monitoring are achieved; a stable heating process is ensured; and the user experience and safety are improved.

[0093]When the sensor 72 detects that there is no air flowing in the air guide channel 12, the sensor 72 feeds back corresponding data to the control module. After receiving the data, the control module recognizes that the user does not smoke. In addition, in a case that the temperature of the air in the air guide channel 12 is greater than or equal to a preset temperature W2 and less than a preset temperature W1, the control module controls the second heating module 7 to reduce working power.

[0094]Specifically, the second heating module 7 reduces its working power to 1%-20% of the maximum working power, and the control module flexibly adjusts the working power of the second heating module 7 according to the temperature of the air inside the air guide channel 12.

[0095]It should be noted that a user can also set a decrease range of the working power of the second heating module 7 according to a preference of the user. For example, it is set that the working power of the second heating module 7 is reduced to 1%, 2%, 3%, 4%, or 5% of the maximum working power to save electricity if the user does not smoke for a long time.

[0096]It is set that the working power of the second heating module 7 is reduced to 6%, 7%, 8%, 9%, or 10% of the maximum working power if the user does not intend to keep smoking.

[0097]For leisure smoking, it is set that the working power of the second heating module 7 is reduced to 11%, 12%, 13%, 14% or 15% of the maximum working power.

[0098]For smoking at any time, it is set that the working power of the second heating module 7 is reduced to 16%, 17%, 18%, 19%, or 20% of the maximum working power.

[0099]When the sensor 72 detects that there is no air flowing in the air guide channel 12, the sensor 72 feeds back corresponding data to the control module. The control module recognizes that the user does not smoke. In addition, in a case that the temperature of the air in the air guide channel 12 is greater than or equal to a preset temperature W2, the control module controls the second heating module 7 to stop working.

[0100]E. When the atomization timer reaches the set atomization time T1, the control module sends a warning through the display 9, to remind a user that continuing to smoke will burn the tobacco paste and produce a burnt smell. In this case, the control module controls both the first heating module 3 and the second heating module 7 to reduce their working powers or to stop working.

[0101]Specifically, both the first heating module 3 and the second heating module 7 reduce their working powers to 1%-80% of the maximum working powers, and the control module flexibly adjusts the working powers of the first heating module 3 and the second heating module 7 according to the temperature of the air inside the air guide channel 12.

[0102]A user can also set a decrease range of the working powers of the first heating module 3 and the second heating module 7 according to a preference of the user. For example, to replace the tobacco paste, the working powers of both the first heating module 3 and the second heating module 7 are reduced to 1%-20% of the maximum working powers, which may specifically be 1%, 5%, 10%.

[0103]It is set that the working powers of both the first heating module 3 and the second heating module 7 are reduced to 20%-40% of the maximum working powers, which may specifically be 20%, 30%, 40%.

[0104]For smoking at any time, the working powers of both the first heating module 3 and the second heating module 7 are reduced to 40%-60% of the maximum working powers, which may specifically be 41%, 50%, 60%.

[0105]If the user likes a burnt smell in the tobacco paste, the working powers of both the first heating module 3 and the second heating module 7 are reduced to 60%-80% of the maximum working powers, which may specifically be 61%, 70%, 80%.

[0106]The first heating module 3 is responsible for quickly heating the heat conduction base 1 to the preset atomization temperature N1° C., and the second heating module 7 adjusts the temperature of the ventilation channel 41 according to the flowing and temperature of the air inside the air guide channel 12. The atomization effect is optimized; the energy consumption is reduced; and intelligent adjustment is achieved according to the smoking action of the user, to avoid overheating or insufficient temperature.

[0107]The user can set the specific atomization temperature N1° C. and the atomization time T1 according to the type of the tobacco paste, and the control module controls the heating process according to this and sends a prompt when set conditions are satisfied. This ensures the taste and flavor of the smoke, and avoids burning of the tobacco paste, to enhance the user experience.

[0108]The sensor 72 detects flowing of the air inside the air guide channel 12. The control module determines, based on this, whether the user is smoking, and adjusts a working state of the second heating module 7, to achieve intelligent response. The temperature is increased only when the user is smoking, so that the energy is saved, and the safety and comfort level of the smoking process are ensured.

[0109]According to the temperature of the air inside the air guide channel 12, the control module implements different power control strategies on the second heating module 7. When the temperature is greater than W2, the working power is reduced or the heating is stopped. When the temperature is between W1 and W2, the power is reduced. This effectively manages the temperature, prevents overheating, reduces the energy consumption, and prolongs the service life of the device.

[0110]When the atomization time reaches the set T1, the control module sends a warning through the display 9 and controls the heating module to reduce the power or stop working. This prevents the tobacco paste from being burnt, avoids an unpleasant odor, protects the device from being damaged, and enhances the user experience and safety.

[0111]The electronic hookah heater achieves intelligent temperature and time control through the integrated control module and the sensor 72. Due to the design of the two heating modules, a heating state is automatically adjusted according to the smoking action of the user and the temperature inside the air guide channel 12, which effectively enhances the atomization effect and the user experience, reduces the energy consumption, and improves the safety and durability of the device.

[0112]As shown in FIG. 9, in some embodiments, second heat conduction and insulation layer 8 are arranged at upper and lower ends of the second heating module 7. In some embodiments, a second heat conduction and insulation layer 8 is arranged at a portion of the sealing cover 2 that is in contact with the second heating module 7. In some embodiments, a second heat conduction and insulation layer 8 is arranged at a portion of the heat conductor 6 that is in contact with the second heating module 7.

[0113]The second heat conduction and insulation layer 8 can effectively reduce heat loss on a contact surface, thereby improving the thermal efficiency of the entire second heating module 7.

[0114]The second heat conduction and insulation layer 8 is made of insulation ceramic, which can achieve insulation, without affecting heat transfer. In other embodiments, the second heat conduction and insulation layer 8 can be made of a mica sheet, quartz, or a ceramic material.

[0115]As shown in FIG. 9, specifically, the second heat conduction and insulation layer 8 of another embodiment includes a second insulation layer 81 and a second heat conduction layer 82. The second insulation layer 81 and the second heat conduction layer 82 are arranged at the upper and lower ends of the second heating module 7.

[0116]The second insulation layer 81 directly covers the upper and lower ends of the second heating module 7, to play an electrical insulation role, which effectively prevents current leakage and a short circuit risk, and improves the safety of the device.

[0117]The second heat conduction layer 82 is clung to the second insulation layer 81, which can quickly transfer the heat generated by the second heating module 7, so that accumulation of the heat around the second heating module 7 is reduced, and the thermal efficiency is improved.

[0118]The second insulation layer 81 is made of insulation ceramic, which can achieve insulation, without affecting heat transfer. In other embodiments, the second insulation layer 81 can be made of a mica sheet, quartz, or a ceramic material.

[0119]The second heat conduction layer 82 is made of heat conduction silicone grease. In other embodiments, the second heat conduction layer 82 can also be made of a ceramic material, a carbon-based material, a polymer composite material, and the like, to ensure uniform heat transfer of the second heat conduction layer 82.

[0120]As shown in FIG. 9, in another embodiment, the second heat conduction and insulation layer 8 includes second metal oxide layers 83. The second metal oxide layers 83 are respectively arranged at the portion of the sealing cover 2 that is in contact with the second heating module 7 and the portion of the heat conductor 6 that is in contact with the second heating module 7.

[0121]The second metal oxide layers 83 serve as heat conduction and insulation layers, which can quickly transfer the heat generated by the second heating module 7 to the sealing cover 2 and the heat conductor 6, and maintain electrical isolation, prevent current leakage, and ensure the safety of the device

[0122]Specifically, each second metal oxide layer 83 can be an aluminum oxide layer, a titanium oxide layer, a zinc oxide layer, or aluminum nitride. Preferably, the second metal oxide layers 83 of this embodiment are the aluminum oxide layers.

[0123]As shown in FIG. 7, the heat conductor 6 of this embodiment includes a first heat conduction element 61 and a second heat conduction element 62. The second heat conduction element 62 is stacked at a top of the first heat conduction element 61. The second heating module 7 is arranged at a top or a bottom of the heat conductor 6.

[0124]By stacking the second heat conduction element 62 at the top of the first heat conduction element 61, a heat dissipation area is enlarged, thereby improving the heat dissipation efficiency.

[0125]The second heating module 7 can be arranged at the top or bottom of the first heat conduction element 61. This design provides higher flexibility, so that the second heating module 7 to be customized and optimized according to an actual application scenario.

[0126]As shown in FIG. 8, a retainer ring 63 for changing a flowing direction of air inside the ventilation channel 41 is arranged between the first heat conduction element 61 and the second heat conduction element 62 of this embodiment.

[0127]The retainer ring 63 can also change a flowing direction of the air in the ventilation channel 41, thereby prolonging time for the air to flow in the ventilation channel 41, and ensuring that the air undergoes sufficient heat exchange in the ventilation channel 41 to increase the temperature of the air.

[0128]As shown in FIG. 6, FIG. 7, and FIG. 8, a heat transfer member 24 is arranged at an upper part of the sealing cover 2 of this embodiment. The heat transfer member 24 is provided with a heat transfer channel 241. The heat transfer channel 241 communicates the air guide channel 12 with the ventilation channel 41. The heat transfer channel 241 is provided with a heat transfer cavity 242.

[0129]The heat transfer member 24 is arranged on the sealing cover 2. The heat transfer member 24 can transfer the heat radiated by the first heating module 3 to the sealing cover 2. The heat transfer channel 241 is used to communicate the air guide channel 12 to the ventilation channel 41, which can effectively transfer the heat. This distributes the heat more quickly and uniformly, thereby improving the heat transfer efficiency of the entire system and allowing for a partial temperature increase before the air enters the air guide channel 12.

[0130]The heat transfer cavity 242 arranged inside the heat transfer channel 241 further improves the heat transfer and storage capabilities. This design not only provides a sealing function for the sealing cover 2, but also has multiple functions of heat transfer and storage, thus improving the overall performance of the device.

[0131]Specifically, a matching portion 243 that is in cooperative connection to the air intake volume control member 4 is arranged at an upper part of the heat transfer member 24, and a lower part of the air intake volume control member 4 presses against the matching portion 243.

[0132]An upper edge of the first heating module 3 is designed with a specific shape or structure such as a thread, a clamping slot, and a flange, as an interface connected to the air intake volume control member 4. This ensures that the air intake volume control member 4 can be securely mounted on the first heating module 3, and does not easily fall off or is not easily loosened, thereby improving the overall stability and durability of the electronic hookah heater. In this embodiment, the matching portion 243 being a clamping slot is taken as an example.

[0133]The lower part of the air intake volume control member 4 is designed with a structure that is matched with the matching portion 243 of the first heating module 3. When the air intake volume control member 4 is mounted on the first heating module 3, its lower part is in close contact with the matching portion 243 to achieve a sealing or fixing effect. This improves the tightness of connection between the first heating module 3 and the air intake volume control member 4, and prevents external impurities or moisture from entering the air intake volume control member 4.

[0134]As shown in FIG. 7, protrusions 244 are arranged at the second heat conduction element 62 and the heat transfer member 24. Recesses 64 are provided in upper and lower ends of the first heat conduction element 61. The protrusions 244 are connected to the recesses 64.

[0135]The design of the connection between the protrusions 244 and the recesses 64 enhances the connection strength of the first heat conduction element 61 and the second heat conduction element 62, as well as of the first heat conduction element 61 and the heat transfer member 24, so that the entire structure is more stable and can withstand external impacts and vibrations and ensure stable operations of the device.

[0136]The connection between the protrusions 244 and the recesses 64 enlarges a heat dissipation area, which helps transfer the heat more effectively from the first heat conduction element 61 to the second heat conduction element 62, and ultimately dissipate the heat into the ventilation channel 41, thus improving the heat dissipation efficiency.

[0137]The design of the protrusions 244 and the recesses 64 may make an assembling process of the heat conductor 6 and the heat transfer member 24 simpler and faster. This reduces alignment and fixing steps in the assembling process, reduces the manufacturing costs, and improves the production efficiency.

[0138]As shown in FIG. 11, the joint between the ventilation channel 41 and the outside of this embodiment is arranged at a top of the air intake volume control member 4. The ventilation valve 42 is a pick. The ventilation valve 42 is rotationally connected to the air intake volume control member 4. A first vent hole 421 is provided in a top of the ventilation valve 42 in a penetrating manner.

[0139]By controlling an overlapping degree between the first vent hole 421 and the ventilation channel 41, the amount of the external air that enters the ventilation channel 41 is controlled. The ventilation valve 42 uses the pick, which has the characteristics of being lightweight and easy to operate. The pick rotates to open or close the ventilation channel 41, to easily control an air flow volume. An air control mechanism is simplified, and a user only needs to simply toggle the pick to quickly adjust a ventilation volume.

[0140]The joint between the ventilation channel 41 and the outside of this embodiment is arranged at a side portion of the air intake volume control member 4. The ventilation valve 42 is a screw cap. The ventilation valve 42 is rotationally connected to the air intake volume control member 4. A second vent hole 422 is provided in a side portion of the ventilation valve 42 in a penetrating manner.

[0141]By controlling an overlapping degree between the second vent hole 422 and the ventilation channel 41, the amount of the external air that enters the ventilation channel 41 is controlled. The screw cap can be conveniently rotated to adjust the overlapping degree between the second vent hole 422 and the ventilation channel 41.

[0142]The joint between the ventilation channel 41 and the outside s arranged at a top of the air intake volume control member 4. The ventilation valve 42 is a screw cap. The ventilation valve 42 is in threaded connection to the air intake volume control member 4. A third vent hole 423 is provided in a side portion of the ventilation valve 42 in a penetrating manner.

[0143]By rotating the ventilation valve 42, the ventilation valve 42 rises or falls along the air intake volume control member 4 to control a position between the ventilation valve 42 and the air intake volume control member 4, thereby adjusting an opening amplitude of the third vent hole 423 to control the amount of the external air entering the ventilation channel 41.

[0144]The ventilation valve 42 rises along the air intake volume control member 4, to increase the opening amplitude of the third vent hole 423. The ventilation valve 42 falls along the air intake volume control member 4, to decrease the opening amplitude of the third vent hole 423.

[0145]As shown in FIG. 1 to FIG. 3, an anti-scald ring 43 is arranged at the air intake volume control member 4 of this embodiment. The anti-scald ring 43 is connected to an outer side of the air intake volume control member 4 and is spaced apart from the air intake volume control member 4 by a thermal insulation gap 44.

[0146]The thermal insulation gap plays a thermal insulation role. When the second heating module 7 works, the generated heat is mainly absorbed by the air intake volume control member 4 and conducted to the external environment. The thermal insulation gap effectively blocks the transfer of the heat directly to the anti-scald ring 43. The presence of thermal insulation gap greatly reduces the temperature of the anti-scald ring 43. Even if the air intake volume control member 4 is heated due to the operation of the second heating module 7, a user will not feel too hot when touching the anti-scald ring 43, thus effectively prevents a scald accident.

[0147]Specifically, the air intake volume control member 4 is provided with a mounting portion 401 connected to the anti-scald ring 43, and the anti-scald ring 43 is provided with a connection member 431. The connection member 431 is connected to the mounting portion 401.

[0148]The mounting portion 401 (such as a threaded hole and a buckle slot) is a foundation for being connected to the anti-scald ring 43. The anti-scald ring 43 is connected to the air intake volume control member 4 by connecting the connection member 431 to the mounting portion 401.
