[0001] This application claims priority to Chinese Patent Application No. 202620192915.5, filed on February 09, 2026, the contents of which are herein incorporated by reference in their entireties.

TECHNICAL FIELD

[0002] The present application relates to the field of electronic cigarettes, and in particular, to an electronic cigarette vaporizer assembly and an electronic cigarette.

BACKGROUND

[0003] Electronic cigarettes, as electronic products simulating traditional cigarettes, have a high degree of similarity to traditional cigarettes in terms of appearance, the state of aerosol generated during use, and the user experience. They are often widely used as substitutes for traditional cigarettes.

[0004] An electronic cigarette generally comprises a housing, a vaporizer assembly, and an electronic control assembly. The housing is provided with an air inlet and an air outlet. The vaporizer assembly is disposed inside the housing and is used to atomize a vaporizable liquid into an aerosol. The electronic control assembly supplies power to and controls the vaporizer assembly. During user inhalation, external air enters the vaporizer assembly through the air inlet and then carries the aerosol generated by heating the vaporizable liquid by the vaporizer assembly through the air outlet into the user's mouth. Most existing electronic cigarettes have a vaporizer assembly comprising, arranged sequentially from the outside to the inside, a metal center post, wicking cotton, a ceramic atomizing core, and a heating coil. This allows the vaporizable liquid to enter the wicking cotton through an oil inlet in the metal center post, then permeate into the ceramic atomizing core through the wicking cotton, and finally be heated and atomized into aerosol vapor by the heating coil. The wicking cotton wraps around the periphery of the ceramic atomizing core to fill the gap between the metal center post and the atomizing core, thereby forming a flexible seal to prevent e-liquid from leaking through the gap after entering the oil inlet.

[0005] Regarding the aforementioned related art, when the heating coil heats the vaporizable liquid, the wicking cotton is prone to charring, thereby producing a burnt odor. This leads to the aerosol vapor being mixed with the burnt odor, resulting in poor taste and reducing the user experience.

SUMMARY

[0006] In order to better restore the effect of the vaporizable liquid and improve the user experience, the present application provides an electronic cigarette vaporizer assembly and an electronic cigarette.

[0007] The technical solution adopted by the electronic cigarette vaporizer assembly and electronic cigarette provided in the present application is as follows:

[0008] An electronic cigarette vaporizer assembly comprises a ceramic center post, a ceramic core, and a heating coil. The ceramic center post is provided with a through-going central airflow channel and at least one oil inlet. The ceramic core is disposed within the central airflow channel, and a portion of an outer wall of the ceramic core is sintered as one piece with a corresponding portion of an inner wall of the ceramic center post. The at least one oil inlet is located on a wall portion of the ceramic center post that is sintered as one piece with the ceramic core. The heating coil is disposed on the ceramic core and is configured to heat and atomize a vaporizable liquid.

[0009] Optionally, the ceramic core comprises at least one vaporization surface. The at least one vaporization surface is arranged opposite to the at least one oil inlet. The heating coil is attached to the at least one vaporization surface.

[0010] An electronic cigarette comprises a housing, a vaporizer assembly, and an electronic control assembly. The housing is provided with an air outlet, an oil reservoir, and an air inlet. The vaporizer assembly is disposed in the housing and is used for atomizing a vaporizable liquid. The air outlet is in fluid communication with the vaporizer assembly. The air inlet is in fluid communication with the vaporizer assembly. The vaporizable liquid from the oil reservoir can enter the vaporizer assembly. The electronic control assembly is disposed in the housing and is used for supplying power to and controlling the vaporizer assembly.

[0011] Optionally, the housing is formed with a condensate chamber, and the condensate chamber is provided with absorbent cotton.

[0012] Optionally, the condensate chamber is provided with a silicone base seal. The silicone base seal is formed with a wick channel and a liquid guide channel. The liquid guide channel is used for guiding liquid to the wick channel. The absorbent cotton is threaded through and placed in the wick channel.

[0013] Optionally, the silicone base seal is fixedly provided with an air intake standpipe, and the air intake standpipe is in fluid communication with the air inlet.

[0014] Optionally, the electronic control assembly comprises a circuit board, a battery module, and a control button. The circuit board is electrically connected to the battery module and to the vaporizer assembly. The control button is fixedly and electrically connected to the circuit board and is used for turning the electronic cigarette on or off.

[0015] Optionally, the electronic control assembly further comprises a sensor module. The sensor module is disposed on the housing and is electrically connected to the circuit board. When a user draws on the air outlet, the sensor module senses air flow and transmits a signal to the circuit board to control the vaporizer assembly to start the atomization operation.

[0016] Optionally, the housing comprises an outer shell, an atomizer bracket, a trim ring, an oil tank, a fill port plug, a mouthpiece housing, and a mouthpiece plug. The atomizer bracket is detachably connected to the outer shell. The trim ring is detachably connected to the atomizer bracket. The oil tank is detachably connected to the trim ring. The fill port plug is detachably connected to the oil tank. The mouthpiece housing is detachably connected to the oil tank. The mouthpiece plug is detachably connected to the mouthpiece housing.

[0017] The atomizer bracket supports the vaporizer assembly. The oil reservoir is located within the oil tank. The fill port plug is used for opening or closing the oil reservoir. The air outlet is located on the mouthpiece housing. The mouthpiece plug is used for opening or closing the air outlet.

[0018] The fill port plug is formed with a fill port. The fill port is in fluid communication with the oil reservoir. The mouthpiece housing is fixedly provided with a sealing post. The sealing post extends through the fill port and is used for sealing the fill port.

[0019] Optionally, a light guide film is disposed between the outer shell and the atomizer bracket. The light guide film is used for light guiding. A first portion of the light guide film is configured as a light-transmissive structure. A second portion of the light guide film is configured as a non-light-transmissive structure. Light passes through the light-transmissive structure of the light guide film to achieve light guiding by the light guide film.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] By sintering a portion of the outer wall of the ceramic core and a portion of the inner wall of the ceramic center post as one piece, a gap between the two can be avoided. Moreover, by setting the oil inlet on the wall portion of the ceramic center post that is sintered as one piece with the ceramic core, the vaporizable liquid entering from the oil inlet can directly enter the ceramic core, avoiding the problem of liquid leakage through a gap. Therefore, the technical solution of the present application does not require wicking cotton to fill the gap between the ceramic center post and the ceramic core, reducing or eliminating the wicking cotton. Consequently, when the heating coil generates heat, it will not cause the wicking cotton to char. This better restores the effect of the vaporizable liquid and improves the user experience. It also prevents users from inhaling substances produced by charred wicking cotton when using the electronic cigarette, thereby addressing the issue in prior art where the vaporizable liquid is conducted to the ceramic atomizing core via wicking cotton for atomization and then heated by a heating coil for atomization, which is prone to causing wicking cotton to char during heating, leading to users inhaling substances generated from charred wicking cotton along with the aerosol, resulting in poor aerosol taste and reduced user experience.

DETAILED DESCRIPTION OF EMBODIMENTS

[0037] The present application is described in further detail below in conjunction with FIGS. 1-14.

[0038] Embodiments of the present application disclose an electronic cigarette vaporizer assembly and an electronic cigarette. Referring to FIGS. 1 and 2, the electronic cigarette vaporizer assembly and electronic cigarette comprise a housing, a vaporizer assembly, and an electronic control assembly. The housing is provided with an air outlet, an oil reservoir, and an air inlet. The vaporizer assembly is disposed within the housing and is configured to atomize a vaporizable liquid. The air outlet is in fluid communication with the vaporizer assembly.The air inlet is in fluid communication with the vaporizer assembly.The vaporizable liquid from the oil reservoir can enter the vaporizer assembly. The electronic control assembly is disposed within the housing and is configured to supply power to and control the vaporizer assembly.

[0039] Referring to FIGS. 2 to 4, in the embodiment of the present application, the housing comprises an outer shell , an atomizer bracket , a trim ring, an oil tank, a fill port plug, a mouthpiece housing , and a mouthpiece plug. The atomizer bracket is detachably connected to the outer shell. The trim ring is detachably connected to the atomizer bracket. The oil tank is detachably connected to the trim ring. The fill port plug is detachably connected to the oil tank . The mouthpiece housing is detachably connected to the oil tank. The mouthpiece plug is detachably connected to the mouthpiece housing. The atomizer bracket supports the vaporizer assembly. The oil reservoir is located within the oil tank. The fill port plug is configured to open or close the oil reservoir. The air outlet is located on the mouthpiece housing. The mouthpiece plug is configured to open or close the air outlet. The fill port plug is formed with a fill port in fluid communication with the oil reservoir. The mouthpiece housing is fixedly provided with a sealing post. The sealing post extends through the fill port to seal the fill port. It is to be understood that the detachable connection between the mouthpiece plug and the mouthpiece housing is achieved by the mouthpiece plug being inserted into the air outlet with an interference fit, thereby establishing the connection between the mouthpiece plug and the mouthpiece housing. The aforementioned other detachable connections are all realized by mutual engagement of protruding blocks and corresponding recesses. In other embodiments, the aforementioned detachable connections can also be implemented using other methods, such as magnetic fixation or other detachable means.

[0040] Referring to FIGS. 2 and 5, in the embodiment of the present application, the electronic control assembly comprises a circuit board , a battery module, and a control button . Both the circuit board and the battery module are disposed within the interior of the atomizer bracket. The circuit board is electrically connected to the battery module and to the vaporizer assembly. The circuit board is fixedly and electrically connected to a charging module. The charging module is exposed on the exterior of the outer shell and is configured to charge the battery module. The control button is fixedly and electrically connected to the circuit board and is configured to turn the electronic cigarette on or off. It can be understood that the turning on or off of the electronic cigarette by the control button can be achieved by pressing the control button , for example, the electronic cigarette turns on after a first press of the control button and turns off after a second press.

[0041] Referring to FIGS. 2 and 5, in a further embodiment, the electronic control assembly further comprises a silicone button cover. The silicone button cover is disposed between the outer shell and the atomizer bracket and abuts against the control button. Pressing the silicone button cover enables actuation of the control button. It is to be understood that a portion of the silicone button cover is exposed on the exterior of the outer shell to facilitate user operation.

[0042] Referring to FIGS. 2 and 5, in a further embodiment, the electronic control assembly further comprises a sensor module. The sensor module is disposed adjacent to the fill port plug and is electrically connected to the circuit board. When a user draws on the air outlet, the sensor module detects airflow and transmits a signal to the circuit board to initiate the vaporization operation of the vaporizer assembly. It is to be understood that during user inhalation, air entering the device through the air inlet is split into two paths: a first portion enters the vaporizer assembly and subsequently exits through the air outlet; a second portion passes through or around the vaporizer assembly and ultimately exits through the air outlet.

[0043] Referring to FIG. 6, in the embodiment of the present application, a light guide film is disposed between the outer shell and the atomizer bracket. The light guide film is configured for light guiding. It is to be understood that a first portion of the light guide film is configured as a light-transmissive structure, and a second portion of the light guide film is configured as a non-light-transmissive structure. The light-transmissive structures of the light guide film can form various patterns, so that when light passes through the light guide film , the various patterns formed by the light-transmissive structures can be better displayed, thereby providing a superior visual effect for the electronic cigarette. Furthermore, while providing a better visual effect, the production cost of the light guide film is relatively low, and its patterns are rich, allowing for diversified production. It can be understood that the outer shell is made of a light-transmissive material, thereby allowing users to observe the patterns on the light guide film through the outer shell .

[0044] Referring to FIG. 6, in a further embodiment, the circuit board is integrally provided with a light-emitting module. The electronic control assembly further comprises an indicator light guide (silicone) . The indicator light guide is formed with a light guide channel. The atomizer bracket is formed with a through-going indicator window . The indicator light guide is disposed through the indicator window and abuts against the circuit board. This configuration allows light emitted from the light-emitting module to pass through the light guide channel and exit via the indicator window , thereby transmitting the light to the light guide film.

[0045] Referring to FIGS. 5 and 7, in the embodiment of the present application, the atomizer bracket is formed with a condensate chamber. The condensate chamber is provided with wick cotton. It is to be understood that the condensate chamber is located at the bottom of the vaporizer assembly. Consequently, any oil that flows into the vaporizer assembly but is not vaporized, or any oil that condenses within it, will ultimately drain into the condensate chamber and be absorbed by the wick cotton, thereby preventing oil leakage from the device. In a further embodiment, the condensate chamber is sealed by a silicone base seal. Specifically, the silicone base seal seals one end of the condensate chamber, ensuring that oil entering the chamber cannot flow out from that end. The silicone base seal is formed with a wick channel and a liquid guide channel. The liquid guide channel is configured to guide the collected oil towards the wick channel. The wick cotton is threaded through and housed within the wick channel, enabling it to more effectively absorb the oil. In a further embodiment, the silicone base seal is integrally formed with an air intake standpipe. The air intake standpipe is in fluid communication with the air inlet, thereby allowing external air entering the device through the air inlet to pass through the air intake standpipe into the condensate chamber, and from there into the interior of the vaporizer assembly. It is to be understood that the air intake standpipe is a hollow structure whose orifice is positioned above the surface of the silicone base seal. This elevated design ensures that if oil accumulates on the surface of the seal, it cannot flow out through the air intake standpipe .

[0046] Referring to FIGS. 8 to 14, in the embodiment of the present application, the vaporizer assembly comprises a ceramic center post, a ceramic core , and a heating coil. The ceramic center post is provided with a through-going central airflow channel and at least one oil inlet in communication with the central airflow channel . The ceramic core is disposed within the central airflow channel , and an outer wall of the ceramic core is sintered as one piece with an inner wall of the ceramic center post. The ceramic core blocks the oil inlet(s) such that the vaporizable liquid entering the central airflow channel from the oil inlet(s) must pass through the ceramic core. The heating coil is disposed on the ceramic core and is configured to heat and atomize the vaporizable liquid. It is to be understood that one end of the central airflow channel is in fluid communication with the air outlet, and the other end is in fluid communication with the condensate chamber. This allows the aerosol generated by the vaporizer assembly heating the vaporizable liquid within the central airflow channel to be drawn by the user through the air outlet. Furthermore, any oil that flows into the vaporizer assembly but is not vaporized, or any oil that condenses within it, can also enter the condensate chamber via the central airflow channel . Additionally, it is to be understood that the ceramic core can be of a hollow structure or other structures, which is not limited in the present application. It is also to be understood that the ceramic center post is located within the oil tank , enabling the oil inlet(s) to be in fluid communication with the oil reservoir, thereby allowing oil from the reservoir to enter the vaporizer assembly through the oil inlet(s). In other embodiments, the ceramic center post can also be replaced with a stainless steel center post or a quartz glass center post.

[0047] Referring to FIGS. 8 to 14, in a further embodiment, the ceramic core comprises at least one vaporization surface. The vaporization surface(s) is/are arranged opposite to the oil inlet(s) . The heating coil is attached to the vaporization surface(s). It is to be understood that the number of oil inlets may be one or more, and the number of oil inlets may differ from the number of vaporization surfaces, provided that each vaporization surface is arranged opposite to at least one oil inlet . This configuration allows the vaporizable liquid, after flowing through the oil inlet(s) , to directly permeate into the vaporization surface(s) for vaporization, thereby improving the vaporization efficiency of the vaporizer assembly. Furthermore, the number of heating coils may also be one or more. A plurality of heating coils can all be attached to the same vaporization surface, or can be respectively attached to different vaporization surfaces. It is to be understood that existing ceramic cores generally have an arcuate shape, which can cause the heating coil to deform when attached to the ceramic core , leading to poor contact between the heating coil and the ceramic core. Simultaneously, when the ceramic core is arcuate or circular, its wall thickness tends to be uneven (thicker in some areas), making it prone to deformation during manufacturing. In the embodiment of the present application, providing the vaporization surface(s) for the heating coil(s) to attach to solves the aforementioned problems associated with existing ceramic cores. This results in more stable contact between the ceramic core and the heating coil(s) , a larger vaporization area for the ceramic core , more uniform heating area, reduced reliance on arcuate or circular structures in the ceramic core , and consequently, a thinner wall thickness for the ceramic core .

[0048] Referring to FIGS. 8 to 14, in a further embodiment, a tank seal is additionally disposed between the oil tank and the atomizer bracket . One end of the ceramic center post is connected to the tank seal, and the other end is connected to the fill port plug. This configuration prevents oil from the oil reservoir from leaking through any gap between the oil tank and the ceramic center post.

[0049] Referring to FIGS. 8 to 14, embodiments of the present application also provide an electronic cigarette vaporizer assembly. This vaporizer assembly is the vaporizer assembly described in the aforementioned embodiments.

[0050] The operating principle of the electronic cigarette according to the embodiments of the present application is as follows: When a user wishes to use the electronic cigarette, the mouthpiece plug is removed, thereby opening the air outlet. Subsequently, the circuit board is activated via the control button , turning on the electronic cigarette. When the user draws on the air outlet, the inhalation action is sensed by the sensor module, causing the vaporizer assembly to begin operation to heat and atomize the vaporizable liquid into an aerosol. Finally, external air enters the vaporizer assembly through the air inlet, carries the aerosol from the vaporizer assembly, and exits through the air outlet into the user's mouth.

[0051] When the vaporizer assembly atomizes the vaporizable liquid, the liquid enters the oil inlet(s) , then permeates into the central airflow channel through the microporous structure of the ceramic core and is preliminarily atomized by the ceramic core. The vaporizable liquid entering the central airflow channel is then heated and atomized by the heating coil, transforming it into an aerosol for the user to inhale. The aforementioned technical solution reduces or eliminates the need for wicking cotton. Consequently, when the heating coil generates heat, it will not cause the wicking cotton to char. The vaporizer assembly has a large surface area and uniform heating distribution, better restoring the effect of the vaporizable liquid and improving the user experience. It prevents users from inhaling substances produced by charred wicking cotton when using the electronic cigarette, thereby addressing the issue in prior art where the vaporizable liquid is conducted to the ceramic core via wicking cotton for atomization and then heated by a heating coil, which is prone to causing wicking cotton to char during heating, leading to users inhaling substances generated from charred wicking cotton along with the aerosol, resulting in poor aerosol taste and reduced user experience.

[0052] All the above are preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made to the structure, shape, or principle of the present application shall fall within the scope of protection of the present application.
