[0039]FIG. 1 and FIG. 2 show some exemplary embodiments of an electronic atomization device of the present application. The electronic atomization device may be configured to atomize a liquid atomizable substrate, so that the atomizable substrate generates an aerosol for a user to puff.

[0040]As shown in FIG. 1 to FIG. 4, in some embodiments, the electronic atomization device may include a housing 10, an atomizer 20, and a power supply assembly 30. The housing 10 may be configured to accommodate components such as the atomizer 20 and the power supply assembly 30. In some embodiments, the atomizer 20 is detachably mounted in the housing 10, to facilitate replacement of the atomizer 20. In some other embodiments, alternatively, the atomizer 20 may be directly formed in the housing 10, and is fixed to the housing 10. The atomizer 20 may be configured to atomize the liquid substrate, so that the liquid substrate generates an aerosol for a user to puff. The power supply assembly 30 is disposed in the housing 10, and may be connected to the atomizer 20, for providing electric energy for the atomizer 20.

[0041]In some embodiments, the housing 10 may include a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 may be pieced together. In some embodiments, each of the first housing 11 and the second housing 12 is a hollow structure with one side open. The first housing 11 and the second housing 12 may be pieced together by disposing a clamping structure to form a sealed housing. In some other embodiments, the first housing 11 and the second housing 12 may alternatively be fixed through soldering. In some other embodiments, alternatively, the first housing 11 and the second housing 12 may be an integrally formed structure.

[0042]As shown in FIG. 5 to FIG. 7, in some embodiments, the atomizer 20 includes a liquid storage housing 21, an end cap, and an atomization assembly 25. The liquid storage housing 21 may be configured to store a liquid substrate, and may store at least two different liquid substrates. The end cap may include a first end cap 22 and a second end cap 23. The first end cap 22 and the second end cap 23 may be respectively disposed at two ends of the liquid storage housing 21, and may be detachably assembled with the liquid storage housing 21. The atomization assembly 25 may be disposed in the housing 10, may be specifically mounted in the liquid storage housing 21, and is configured to heat the liquid atomizable substrate delivered from the liquid storage housing 21.

[0043]The atomizer 20 further has an airflow channel 20a and a vent channel 20b, where the airflow channel 20a may be in communication with the atomization assembly 25, so that the aerosol may be outputted. The vent channel 20b may be formed in the liquid storage housing 21, communicates with the airflow channel 20a, and communicates with each liquid storage cavity 213 in the liquid storage housing 21, for performing ventilation for each liquid storage cavity 213 in the liquid storage housing 21. The vent channel 20b may at least partially extend along an air outlet direction of the airflow channel 20a.

[0044]As shown in FIG. 8 to FIG. 10, in some embodiments, the liquid storage housing 21 may be a cylindrical structure, and may have a cross-sectional shape and size matching a cross-sectional shape and size of the housing 10. In some embodiments, at least one end of the liquid storage housing 21 is provided with an opening, and the opening may be covered by using an end cap. Specifically, the liquid storage housing 21 may include a first opening 210 and a second opening 211. The first opening 210 may be disposed at one end of the liquid storage housing 21, and the second opening 211 may be disposed at the other end of the liquid storage housing 21. The first opening 210 is disposed opposite to the second opening 211. A first end cap 22 may cover the first opening 210, and a second end cap 23 may cover the second opening 211. The first end cap 22 may be detachably connected to the first opening 210. Specifically, in some embodiments, the first end cap 22 may be fixed to the liquid storage housing 21 through interference fit. The second end cap 23 may be detachably connected to the second opening 211. Specifically, in some embodiments, the second end cap 23 may be fixed to the liquid storage housing 21 through interference fit.

[0045]In some embodiments, the end cap may be provided with an airflow through-hole, and the airflow channel 20a may be formed in the airflow through-hole. Generally, in some embodiments, the first end cap 22 is provided with a first airflow through-hole 221. The second end cap 23 is provided with a second airflow through-hole 231. The second airflow through-hole 231 and the first airflow through-hole 221 are provided coaxially, and may be provided for mounting of the atomization assembly 25 and communicate with the atomization assembly 25. The airflow channel 20a may be formed in the second airflow through-hole 231, the atomization assembly 25, and the first airflow through-hole 221. An airflow may enter the atomization assembly 25 from the second airflow through-hole 231 and take out the aerosol from the first airflow through-hole 221.

[0046] In some embodiments, a partition structure 212 may be disposed in the liquid storage housing 21. The partition structure 212 may be configured to partition a space in the liquid storage housing 21 into at least two liquid storage cavities 213. The at least two liquid storage cavities 213 are disposed independently of each other. In some embodiments, two liquid storage cavities 213 may be provided, that is, include a first liquid storage cavity 213a and a second liquid storage cavity 213b. The partition structure 212 may partition a space in the liquid storage housing 21 into a first liquid storage cavity 213a and a second liquid storage cavity 213b.

[0047] In some embodiments, the partition structure 212 may include a first partition portion 212a and a second partition portion 212b. The first partition portion 212a is disposed between the first opening 210 and the second opening 211, and extends in a direction perpendicular to the air outlet direction. That is, the first partition portion 212a is parallel to the first opening 210, and transversely cuts a part of the liquid storage housing 21. There may be one second partition portion 212b. The second partition portion 212b may be connected to the first partition portion 212a, and may extend in a direction opposite to the air outlet direction. The second partition portion 212b may have a length less than a height of the liquid storage housing 21, and may extend toward the second opening 211 and extend to the second opening 211. In some other embodiments, there may be a plurality of second partition portions 212b, and the plurality of second partition portions 212b may be disposed at intervals along a circumferential direction of the first partition portion 212a.

[0048] In some embodiments, the partition structure 212 and the liquid storage housing 21 are an integrally formed structure, and the partition structure and the liquid storage housing 21 may be integrally formed through injection molding. In some other embodiments, alternatively, the partition structure 212 and the liquid storage housing 21 may be split structures, and may be fixedly connected by using a clamping structure or through interference fit.

[0049]In some embodiments, the partition structure 212 may be provided with a through-hole 2121. The through-hole 2121 may be provided on the first partition portion 212a, and may be provided toward the first opening 210. The through-hole 2121 may be configured to be threaded by the atomization assembly 25.

[0050]In some embodiments, the partition structure 212 is provided with a vent hole 2122, and the vent hole 2122 may be in communication with the first liquid storage cavity 213a and the second liquid storage cavity 213b. In some embodiments, there may be two vent holes 2122. The two vent holes 2122 are spaced apart on the first partition portion 212a, and are located on two opposite sides of the through-hole 2121.

[0051] The first liquid storage cavity 213a and the second liquid storage cavity 213b are spaced apart independently. A part of the first liquid storage cavity 213a extends toward at least one side of the second liquid storage cavity 213b. Specifically, the first liquid storage cavity 213 may communicate with the first opening 210, and has a part extending from the first opening 210 to the second opening 211. In some embodiments, a longitudinal cross section of the first liquid storage cavity 213a may be approximately in the shape of "7". The first liquid storage cavity 213a has a part formed between the first partition portion 212a and the first opening 210, and a part extending from the first opening 210 to the second opening 211. Specifically, the first liquid storage cavity 213a may include a first storage area 2131 and a second storage area 2132 that communicate with each other. The first storage area 2131 and the second storage area 2132 may be located on two adjacent sides of the second liquid storage cavity 213b. The first storage area 2131 may be located on a side of the second liquid storage cavity 213b that faces the first opening 210, and the second storage area 2131 may be located on a circumferential side of the second liquid storage cavity 213b. Specifically, the first storage area 2131 and the second liquid storage cavity 213b are arranged side by side along the air outlet direction. The second storage area 2132 and the second storage cavity 213b are arranged side by side in a direction perpendicular to the air outlet direction. The first storage area 2131 may be formed between the first partition portion 212a and the first opening 210. The second storage area 2132 communicates with the first storage area 2131 and is formed on a side of the second liquid storage cavity 213b. The second liquid storage cavity 213b is disposed close to the second opening 211, and communicates with the second opening 211. A capacity of the first liquid storage cavity 213a may be greater than a capacity of the second liquid storage cavity 213b.

[0052] In some other embodiments, alternatively, the second storage area 2132 may be located on at least two circumferential sides of the second liquid storage cavity 213b. In some other embodiments, alternatively, the first storage area 2131 and the second liquid storage cavity 213b may be non-coaxially disposed in the air outlet direction, and partially overlap only in the air outlet direction. In a direction perpendicular to the air outlet direction, the second storage area 2132 may only partially overlap the second liquid storage cavity 213b.

[0053] The first liquid storage cavity 213a may be a primary liquid storage cavity, and the second liquid storage cavity 213b may be a secondary liquid storage cavity. Liquid substrates in the first liquid storage cavity 213a and the second liquid storage cavity 213b may be simultaneously atomized. The first liquid storage cavity 213a may store a first liquid substrate. The first liquid substrate may be a main liquid substrate, for example, an electronic liquid or a medical liquid. When the first liquid substrate is atomized, a first aerosol may be generated. The second liquid storage cavity 213b may store a second liquid substrate. The second liquid substrate may be a flavor substance, and a second aerosol generated by the second liquid substrate may be mixed with the first aerosol generated by the first liquid substrate to form a third aerosol. The third aerosol has a taste and/or a flavor different from that of the first aerosol.

[0054] The capacity of the first liquid storage cavity 213a is greater than the capacity of the second liquid storage cavity 213b, so that when the first liquid substrate in the first liquid storage cavity 213a is depleted, most or all of the second liquid substrate in the second liquid storage cavity 213b is consumed, waste of the second liquid substrate in the second liquid storage cavity 213b is reduced, and the capacity of the first liquid storage cavity 213a is increased without changing the total weight of the atomizer 20, thereby increasing the number of atomizable puffs, and diversifying tastes and/or flavors, to meet user requirements, and improve user experience and fun.

[0055] In some embodiments, the liquid storage cavity 213 may alternatively be directly formed in the housing 10. In some other embodiments, the number of liquid storage cavities 213 may be more than two, and may be three, four, five, or the like.

[0056] As shown in FIG. 6, FIG. 11, and FIG. 12, in some embodiments, a liquid storage member 24 may be disposed in the liquid storage cavity 213. The liquid storage member 24 may be configured to adsorb and store the liquid substrate in the liquid storage cavity 213 and may prevent the liquid substrate from leaking out. In some other embodiments, the liquid storage member 24 may alternatively be omitted. A gap between the liquid storage member 24 and an inner wall of the liquid storage housing 21 may form at least part of the vent channel 20b.

[0057] Specifically, in some embodiments, a first liquid storage member 24a may be disposed in the first liquid storage cavity 213a. At least a part of the first liquid storage member 24a extends to at least one side of the second liquid storage cavity 213b. In some embodiments, a shape and a size of the first liquid storage member 24a may match a shape and a size of the first liquid storage cavity 213b. The first liquid storage member 24a may be in interference fit with the liquid storage housing 21. In some other embodiments, the first liquid storage member 24a may alternatively be in clearance fit with the liquid storage housing 21. A gap between the first liquid storage member and the liquid storage housing can be passed by only a gas, but cannot be passed by a liquid. The gap may adsorb the liquid substrate through a capillary action, to prevent the liquid substrate from leaking out.

[0058]In some embodiments, the first liquid storage member 24a is approximately in the shape of "7" and may include a first liquid storage portion 241a and a second liquid storage portion 242a. The first liquid storage portion 241a may be disposed in the first storage area 2131, and the second liquid storage portion 242a may be disposed in the second storage area 2132. The first liquid storage portion 241a and the second liquid storage portion 242a may be connected to each other, may be disposed at a right angle, and may be integrally formed. The first liquid storage portion 241a and the second liquid storage portion 242a are in fluid communication with each other, and a liquid substrate may be transferred from the second liquid storage portion 242a to the first liquid storage portion 241a. Disposing the first liquid storage portion 241a and the second liquid storage portion 242a of the first liquid storage member 24a at a right angle can facilitate mounting of the first liquid storage member 24a and improve the fitting degree between the first liquid storage member 24a and the inner wall of the first liquid storage cavity 213a. Certainly, it may be understood that, in some other embodiments, the first liquid storage portion 241a and the second liquid storage portion 242a may be not limited to being disposed at a right angle.

[0059] In some embodiments, a second liquid storage member 24b may be disposed in the second liquid storage cavity 213b, and the second liquid storage member 24b is approximately cubical in shape. A shape and a size of the second liquid storage member 24b may match a shape and a size of the second liquid storage cavity 213b.

[0060] In some embodiments, the liquid storage member 24 may be made of any appropriate material or combined material of a plurality of materials capable of transferring the liquid aerosol to the atomization device to form the substrate. The appropriate material or combined material may be a capillary material. The capillary material may include a sponge or foam material, a ceramic-based or graphite-based material in the form of fiber or sintered power, a foam metal or plastic material, a fiber material (for example, made of as-spun fiber or pressure-spun fiber (for example, cellulose acetate fiber, a polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyethylene terephthalate fiber, polypropylene fiber, or nylon fiber)), or ceramic. A capillary may have any appropriate capillary function, to be used with physical properties of different liquids.

[0061] The capillary material may include a material that is itself porous, for example, a ceramic material such as alumina (corundum). Alternatively, the porous material may include a material having a plurality of micropores that are manufactured, to allow a liquid aerosol forming substrate to migrate to the atomization device. The porous material may include a hydrophilic material, to improve distribution and diffusion of the liquid aerosol forming substrate. Especially preferably, one or more materials depend on physical properties of the liquid aerosol forming substrate. An example of an appropriate material is a capillary material, for example, a sponge or foam material, a ceramic-based or graphite-based material in the form of fiber or sintered power, a foam metal or plastic material, a fiber material (for example, made of as-spun fiber or pressure-spun fiber (for example, cellulose acetate fiber, a polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyethylene terephthalate fiber, polypropylene fiber, or nylon fiber)), or ceramic. The porous material may have any appropriate porosity, to be used with physical properties of different liquids.

[0062] In some other embodiments, alternatively, the liquid storage member 24 may be made of another material having a capillary channel, or may be made of another material on which micropores or microgrooves having a capillary action are disposed, such as, for example, silica gel, plastic, stainless steel, or glass.

[0063] In some embodiments, a density of the second liquid storage portion 242a of the first liquid storage member 24a may be less than a density of the first liquid storage portion 241a, thereby reducing the residue of the liquid substrate in the first liquid storage member 24a, and improving utilization of the liquid substrate in the first liquid storage member 24a.

[0064]In some embodiments, a via 241 may be disposed on the liquid storage member 24, and the via 241 is disposed coaxially with the first airflow through-hole 221. Specifically, each liquid storage member 24 is provided with a via 241, and the via 241 may be disposed throughout in a thickness direction of the liquid storage member 24. The first liquid storage member 24a may be provided with the via 241 on the first liquid storage portion 241a, and the via 241 of the second liquid storage member 24b may be disposed coaxially with the via 241 of the first liquid storage member 24a. The via 241 may be threaded by using the atomization assembly 25.

[0065] In some embodiments, a side wall of the liquid storage member 24 that is disposed opposite to the liquid storage housing 21 is provided with at least one vent groove 242, and the vent groove 242 may extend along the air outlet direction. In some embodiments, a plurality of vent grooves 242 may be disposed on an outer side wall of the first liquid storage member 24a, and the plurality of vent grooves 242 may be spaced apart along the periphery of the first liquid storage member 24a. There may be four vent grooves 242 on the first liquid storage member 24a. Certainly, it may be understood that, in some other embodiments, the number of vent grooves 242 on the first liquid storage member 24a is not limited to four, and may alternatively be one, two, three, or the like. An outer side wall of the second liquid storage member 24b may be provided with two vent grooves 242, and the two vent grooves 242 may be disposed in a one-to-one correspondence with the two vent holes 2122 on the partition structure 212.

[0066]In some embodiments, the vent hole 2122 may communicate with the vent groove 242 to form at least part of the vent channel 20b. Specifically, the vent groove 242 of the second liquid storage member 24b, the vent hole 2122, and the vent groove 242 of the first liquid storage member 24a communicate with each other to form at least part of the vent channel 20b. In some embodiments, a gap is left between the liquid storage member 24 and the partition structure 212, and the gap may communicate with the vent hole 2122 and the vent groove 242 on the liquid storage member 24, to form the at least part of the vent channel 20b. Generally, a support protrusion 2123 may be disposed on end surfaces of the vent hole 2122 and the through-hole 2121, so that a gap is left between the liquid storage member 24 and the partition structure 212, thereby facilitating forming of the vent channel 20b, and further facilitating ventilation. In some embodiments, a gap is left between the outer side wall of the second liquid storage member 24b and both an inner side wall of the liquid storage housing 21 and the second partition portion 212b, and a gap is left between an end wall of the second liquid storage member 24b that faces the first partition portion 212a and the first partition portion 212a. The gaps may be in communication with the vent hole 2122 and the vent groove 242, to form the at least part of the vent channel 20b. In some embodiments, a gap is left between the first liquid storage member 24a and the first end cap 22. The gap may form the part of the vent channel 20b and communicate with the airflow channel 20a, thereby communicating with the outside by communicating with the airflow channel 20b. The air pressure in the liquid storage cavity 213 may be balanced by using the vent channel 20b, so that the liquid storage cavity 213 supplies the liquid to the atomization assembly 25 more smoothly.

[0067]As shown in FIG. 13 and FIG. 14, in some embodiments, the atomization assembly 25 may be threaded through the at least two liquid storage cavities 213. Specifically, the atomization assembly 25 may be threaded through the first liquid storage cavity 213a and the second liquid storage cavity 213b. The atomization assembly 25 may include an atomization base 251 and at least two heating structures 253. The atomization base 251 may be cylindrical, and may be a structure with two ends open. The atomization base 251 can be threaded through the at least two liquid storage cavities 213. One end of the atomization base 251 may be inserted into the second airflow through-hole 231, and is threaded through the second liquid storage member 24b, the partition structure 212, and the first liquid storage member 24a to the first airflow through-hole 221. The at least two heating structures 253 are disposed at an interval in the atomization base 251, and the at least two heating structures and the atomization base 251 may form an integral structural member, and then are mounted in the liquid storage housing 21. Each heating structure 253 may be disposed corresponding to one liquid storage cavity 213, is in liquid guide communication with the liquid storage cavity 213, and is configured to heat the atomizable substrate delivered from the corresponding liquid storage cavity 213. Specifically, in this embodiment, there may be two heating structures 253. The two heating structures 253 are mounted in the atomization base 251 at an interval. One heating structure 253 may be in fluid communication with the first liquid storage cavity 213a, and the other heating structure 253 may be in fluid communication with the second liquid storage cavity 213b.

[0068]In some embodiments, the atomization base 251 may be a metal tube. Certainly, it may be understood that, in some other embodiments, the atomization base 251 may not be limited to a metal tube, and the atomization base 251 may alternatively be a ceramic tube or a glass tube. In some embodiments, liquid inlets 2511 can be disposed on a side wall of the atomization base 251. The liquid inlets 2511 can be disposed in a one-to-one correspondence with the heating structures 253, and communicate with the liquid storage cavities 213 in a one-to-one correspondence, for the liquid substrate in the liquid storage cavities 213 to enter the heating structures 253.

[0069]In some embodiments, one end of the atomization base 251 that faces the first airflow through-hole 221 is sleeved over the periphery of an atomization tube 252. The atomization tube 252 may extend toward the first airflow through-hole 221, is disposed coaxially with the atomization base 251, and communicates with the atomization base 251.

[0070]In some embodiments, each heating structure 253 may include an atomization core 2531 and a heating body 2532. The atomization core 2531 may be approximately cylindrical, may be a structure with two ends open, and is disposed coaxially with and in communication with the atomization base 251 and the atomization tube 252. A side wall of the atomization core 2531 may be in liquid guide communication with the liquid storage cavity 213 by using the liquid inlet 2511. There may be one heating body 2532 in some embodiments, and the heating body 2532 is disposed on the atomization core 2531. Specifically, the heating body 2532 may be disposed in the atomization core 2531, and adheres to an inner wall of the atomization core 2531. In some other embodiments, the number of heating bodies 2532 may be not limited to one, and may alternatively be two. In this embodiment, the heating body 2532 may have a mesh shape, may be a metal mesh, and may be rolled into a hollow cylindrical structure. In some embodiments, alternatively, the heating body 2532 may be sleeved over the periphery of the atomization core 2531. The heating body 2532 may heat the liquid substrate on the atomization core 2531 in a powered-on state.

[0071] In some embodiments, each heating structure 253 further includes a conductive connection member 2533, and each heating structure may include two conductive connection members 2533. In this embodiment, the conductive connection member 2533 may be a conductive wire. Certainly, it may be understood that, in some other embodiments, the conductive connection member 2533 may not be limited to a conductive wire, and may alternatively be an ejector pin or a conductive plate. The conductive connection member 2533 may be threaded out from the atomization base 251. Specifically, the conductive connections 2533 of the two heating structures 253 may be threaded out from one end of the atomization base 251 that faces the second end cap 23, and be connected to the power supply assembly 30. In this embodiment, one conductive connection member 2533 in the two heating structures 253 may be shared, and therefore the total number of conductive connection members 2533 of the two heating structures 253 may be three. That is, the two heating structures 253 may be disposed in parallel, thereby helping to heat each liquid storage cavity 213 alone. In some other embodiments, alternatively, no conductive connection member 2533 of each heating structure 253 may be shared.

[0072] In some embodiments, the atomization assembly 25 further includes an isolation sealing member 254, and the isolation sealing member 254 may be disposed between the two heating structures 253. The isolation sealing member 254 is located between the atomization base 251 and the partition structure 212, and can seal at least a part of a gap between the atomization base 251 and the partition structure 212, to avoid a case that liquid atomizable substrates in two adjacently disposed liquid storage cavities 213 flow to each other to affect a taste generated by the aerosol, and prevent a liquid leakage phenomenon from occurring.

[0073]In some embodiments, the atomization assembly 25 further includes a wire clipping structure 255. The wire clipping structure 255 is disposed in the atomization base 251 and is located at one end of the atomization base 251 that faces the second end cap 23. The wire clipping structure 255 may be cylindrical, and may be a structure with two ends open. The wire clipping structure 255 may be a cylindrical structure with a circular cross section, and an outer diameter of a middle section may be greater than outer diameters at two ends. A part of an outer wall of the wire clipping structure 255 may be fixed to an inner wall of the atomization base 251 through close contact. The wire clipping structure 255 has a through-hole 2551. The through-hole 2551 may be located at a central axis of the wire clipping structure 255, and may be used for an external airflow to enter the atomization assembly 25. An outer side wall of the wire clipping structure 255 may be provided with a wire clipping groove 2552. There may be a plurality of wire clipping grooves 2552. The plurality of wire clipping grooves 2552 may be spaced apart along a circumferential direction of the wire clipping structure 255. Each conductive connection member 2533 may be clipped in one wire clipping groove 2552. In some embodiments, there may be one wire clipping groove 2552, all the conductive connection members 2533 may be clipped in the one wire clipping groove 2552, and adjacent conductive connection members 2533 may be insulated from each other by disposing an insulated structure. For example, the conductive connection member 2533 may be sheathed with an insulated structure.

[0074] By disposing the wire clipping structure 255, it is unnecessary to additionally provide a wiring channel, a manufacturing process of the atomizer 20 is simplified, a miniaturized design of the atomizer 20 is facilitated, and assembly may be facilitated.

[0075] In some embodiments, the atomizer 20 further includes a liquid absorbing structure 26. The liquid absorbing structure 26 may be mounted on one side of the second end cap 23 that faces away from the liquid storage cavity 213, may be liquid absorbing cotton, and can absorb the liquid substrate that leaks out from the second end cap 23. In some other embodiments, the liquid absorbing structure 26 may be not limited to liquid absorbing cotton.

[0076]In some embodiments, the power supply assembly 30 may include a holder 31 and a power supply 32. The holder 31 may be disposed in the housing 10, and may be located at one end of the atomizer 20. The holder 31 can support the atomizer 20, and may be fixedly clipped to the second end cap 23. The power supply 32 may be disposed on the holder 31, and may be connected to the conductive connection member 2533.
