The atomizing assembly 25 may be disposed in the housing 10, specifically, it may be installed in the liquid reservoir 21 for heating the liquid atomizing substrate delivered from the liquid reservoir 21.

[0041] The atomizer 20 also has an airflow channel 20a and a ventilation channel 20b, wherein the airflow channel 20a can communicate with the atomizing component 25 for aerosol output. The ventilation channel 20b can be formed in the liquid storage shell 21, communicating with the airflow channel 20a and each liquid storage chamber 213 in the liquid storage shell 21, for ventilation of each liquid storage chamber 213 in the liquid storage shell 21. The ventilation channel 20b can extend at least partially along the outlet direction of the airflow channel 20a.

[0042] like Figures 8 to 10As shown, in some embodiments, the liquid storage shell 21 can be a cylindrical structure, and its cross-sectional shape and size can be adapted to the cross-sectional shape and size of the outer shell 10. In some embodiments, at least one end of the liquid storage shell 21 is provided with an opening, which can be closed by an end cap. Specifically, the liquid storage shell 21 may include a first opening 210 and a second opening 211. The first opening 210 may be provided at one end of the liquid storage shell 21, and the second opening 211 may be provided at the other end of the liquid storage shell 21. The first opening 210 and the second opening 211 are disposed opposite to each other. A first end cap 22 can cover the first opening 210, and a second end cap 23 can cover the second opening 211. The first end cap 22 can be detachably connected to the first opening 210. Specifically, in some embodiments, the first end cap 22 can be fixed to the liquid storage shell 21 by an interference fit. The second end cap 23 can be detachably connected to the second opening 211.

[0043] In some embodiments, an airflow hole may be provided on the end cap, and the airflow channel 20a may be formed in the airflow hole. Generally, in some embodiments, a first airflow hole 221 is provided on the first end cap 22, and a second airflow hole 231 is provided on the second end cap 23. The second airflow hole 231 and the first airflow hole 221 are coaxially arranged, and the two can be installed on and communicate with the atomizing component 25.

Airflow can enter the atomizing component 25 from the second airflow hole 231 and carry the aerosol out from the first airflow hole 221.

[0044] In some embodiments, a partition structure 212 may be provided in the liquid storage shell 21 to divide the space in the liquid storage shell 21 into at least two liquid storage chambers 213. These at least two liquid storage chambers 213 are independently arranged. In some embodiments, there may be two liquid storage chambers 213, namely a first liquid storage chamber 213a and a second liquid storage chamber 213b. The partition structure 212 can divide the space in the liquid storage shell 21 into a first liquid storage chamber 213a and a second liquid storage chamber 213b.

[0045] 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 gas outlet direction, that is, the first partition portion 212a is parallel to the first opening 210 and transversely cuts through a portion of the liquid storage shell 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 gas outlet direction. The length of the second partition portion 212b may be less than the height of the liquid storage shell 21, and it may extend toward and to the second opening 211. In other embodiments, there may be multiple second partition portions 212b, which may be spaced circumferentially along the first partition portion 212a.

[0046] In some embodiments, the partition structure 212 and the liquid storage shell 21 are integrally formed, and can be integrally formed with the liquid storage shell 21 by injection molding. In other embodiments, the partition structure 212 and the liquid storage shell 21 can also be separate structures, and the two can be fixed by setting a snap-fit ​​structure or by interference fit.

[0047] In some embodiments, a perforation 2121 may be provided on the partition structure 212. The perforation 2121 may be provided on the first partition portion 212a and may be oriented toward the first opening 210. The perforation 2121 may be used for the atomizing component 25 to pass through.

[0048] In some embodiments, the partition structure 212 is provided with a ventilation hole 2122, which can communicate with the first liquid storage chamber 213a and the second liquid storage chamber 213b. In some embodiments, there can be two ventilation holes 2122, which are spaced apart on the first partition portion 212a and located on two opposite sides of the through hole 2121.

[0049] The first liquid storage chamber 213a and the second liquid storage chamber 213b are independently and separated. The first liquid storage chamber 213a extends to at least one side of the second liquid storage chamber 213b. Specifically, the first liquid storage chamber 213a may communicate with the first opening 210 and extends from the first opening 210 to the second opening 211. In some embodiments, the longitudinal section of the first liquid storage chamber 213a may be approximately "7" shaped, and the first liquid storage chamber 213a is partially formed between the first partition portion 212a and the first opening 210, and extends from the first opening 210 to the second opening 211. Specifically, the first liquid storage chamber 213a may include a first storage area 2131 and a second storage area 2132 that are interconnected. The first storage area 2131 and the second storage area 2132 may be located on adjacent sides of the second liquid storage chamber 213b, wherein the first storage area 2131 may be located on the side of the second liquid storage chamber 213b facing the first opening 210, and the second storage area 2132 may be located on the circumferential side of the second liquid storage chamber 213b. Specifically, the first storage area 2131 and the second liquid storage chamber 213b are arranged side by side along the gas outlet direction. The second storage area 2132 and the second storage chamber 213b are arranged side by side perpendicular to the gas outlet direction. The first storage area 2131 may be formed between the first partition 212a and the first opening 210, and the second storage area 2132 is connected to the first storage area 2131 and is formed on one side of the second liquid storage chamber 213b. The second liquid storage chamber 213b is located near the second opening 211 and is connected to the second opening 211. The capacity of the first liquid storage chamber 213a can be greater than the capacity of the second liquid storage chamber 213b.

[0050] In some other embodiments, the second storage area 2132 may also be located on at least two sides of the second liquid storage chamber 213b in the circumferential direction. In some other embodiments, the first storage area 2131 and the second liquid storage chamber 213b may also be non-coaxial in the gas outlet direction, and they may only partially overlap in the gas outlet direction. In the direction perpendicular to the gas outlet direction, the second storage area 2132 may only partially overlap with the second liquid storage chamber 213b.

[0051] The first liquid storage chamber 213a can be the main liquid storage chamber, and the second liquid storage chamber 213b can be the auxiliary liquid storage chamber. The liquid matrix in the first liquid storage chamber 213a and the second liquid storage chamber 213b can be atomized simultaneously. The first liquid storage chamber 213a can store a first liquid matrix, which can be a main liquid matrix, such as e-liquid or pharmaceutical liquid. When the first liquid matrix is ​​atomized, it can generate a first aerosol. The second liquid storage chamber 213b can store a second liquid matrix, which can be a flavoring substance. The second aerosol generated by the second liquid matrix can mix with the first aerosol generated by the first liquid matrix to form a third aerosol. The third aerosol has a taste and / or flavor different from the first aerosol.

[0052] By making the capacity of the first liquid storage chamber 213a greater than that of the second liquid storage chamber 213b, when the first liquid matrix in the first liquid storage chamber 213a is consumed, most or all of the second liquid matrix in the second liquid storage chamber 213b can also be consumed, reducing the waste of the second liquid matrix in the second liquid storage chamber 213b. Furthermore, the capacity of the first liquid storage chamber 213a is increased without changing the overall weight of the atomizer 20, increasing the number of atomized puffs, and diversifying the taste and / or flavor to meet user needs and enhance the user experience.

[0053] In some embodiments, the liquid storage cavity 213 may also be formed directly in the outer casing 10. In other embodiments, there may be more than two liquid storage cavities 213; there may be three, four, five, etc.

[0054] like Figure 6 , Figure 11 and Figure 12 As shown, in some embodiments, a liquid storage element 24 may be provided in the liquid storage cavity 213. The liquid storage element 24 can be used to adsorb and store the liquid matrix in the liquid storage cavity 213 and prevent the liquid matrix from leaking out. In other embodiments, the liquid storage element 24 may be omitted. The gap between the liquid storage element 24 and the inner wall of the liquid storage shell 21 can form at least a partial ventilation channel 20b.

[0055] Specifically, in some embodiments, a first liquid storage element 24a may be disposed in the first liquid storage cavity 213a. The first liquid storage element 24a extends at least partially to at least one side of the second liquid storage cavity 213b. In some embodiments, the shape and size of the first liquid storage element 24a may be adapted to the shape and size of the first liquid storage cavity 213b. The first liquid storage element 24a may be interference-fitted with the liquid storage shell 21. In other embodiments, the first liquid storage element 24a may also be clearance-fitted with the liquid storage shell 21, the gap between the two being sufficient to allow only gas to pass through and not liquid to pass through, which can adsorb liquid matrix through capillary action, thereby preventing liquid matrix leakage.

[0056] In some embodiments, the first liquid storage member 24a is generally in the shape of a "7" and may include a first liquid storage section 241a and a second liquid storage section 242a. The first liquid storage section 241a may be disposed in a first storage area 2131, and the second liquid storage section 242a may be disposed in a second storage area 2132. The first liquid storage section 241a and the second liquid storage section 242a may be connected, may be arranged at right angles, and may be integrally formed. The first liquid storage section 241a and the second liquid storage section 242a are in fluid communication, and the liquid matrix may be transported from the second liquid storage section 242a to the first liquid storage section 241a. By arranging the first liquid storage portion 241a and the second liquid storage portion 242a of the first liquid storage member 24a at right angles, it is easier to install the first liquid storage member 24a and the fit between the first liquid storage member 24a and the inner wall of the first liquid storage cavity 213a can be improved. Of course, it is understood that in some other embodiments, the first liquid storage portion 241a and the second liquid storage portion 242a may not be limited to being arranged at right angles.

[0057] In some embodiments, a second liquid storage element 24b may be disposed in the second liquid storage cavity 213b, and the second liquid storage element 24b is generally square-shaped. The shape and size of the second liquid storage element 24b are adapted to the shape and size of the second liquid storage cavity 213b.

[0058] In some embodiments, the reservoir 24 may be made of any suitable material or combination of materials capable of delivering a liquid aerosol-forming matrix toward the atomizing device. This material may be a capillary material, which may include sponge or foam material, ceramic-based or graphite-based material in the form of fibers or sintered powder, foamed metal or plastic material, fibrous material (e.g., made of virgin or pressed fibers (e.g., cellulose acetate fiber, polyester fiber, bonded polyolefin fiber, polyethylene fiber, polyester fiber, or polypropylene fiber, nylon fiber)) or ceramic. The capillary may have any suitable capillary action to be used with different liquid physical properties.

[0059] Capillary materials can include materials that are porous themselves, such as ceramic materials like alumina (corundum). Alternatively, porous materials can include materials having multiple fabricated micropores to allow the liquid flotation matrix to migrate into the atomizing device. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the liquid flotation matrix. A particularly preferred one or more materials will depend on the physical properties of the liquid flotation matrix. Examples of suitable materials are capillary materials, such as sponge or foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, foamed metal or plastic materials, fibrous materials (e.g., made from virgin or pressed fibers (e.g., cellulose acetate fibers, polyester fibers, bonded polyolefin fibers, polyethylene fibers, polyester fibers, or polypropylene fibers, nylon fibers)), or ceramics. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0060] In some other embodiments, the liquid reservoir 24 may also be made of other materials with capillary channels, such as silicone, plastic, stainless steel, glass, etc.

[0061] In some embodiments, the density of the second liquid storage portion 242a of the first liquid storage member 24a may be less than the density of the first liquid storage portion 241a, thereby reducing the liquid matrix residue in the first liquid storage member 24a and improving the utilization rate of the liquid matrix in the first liquid storage member 24a.

[0062] In some embodiments, a through hole 241 may be provided on the liquid storage component 24, and the through hole 241 is coaxially arranged with the first air passage 221. Specifically, each liquid storage component 24 is provided with a through hole 241, which can be disposed through the thickness direction of the liquid storage component 24. The through hole 241 may be provided on the first liquid storage portion 241a of the first liquid storage component 24a, and the through hole 241 of the second liquid storage component 24b may be coaxially arranged with the through hole 241 of the first liquid storage component 24a. The through hole 241 can be provided by the atomizing component 25.

[0063] In some embodiments, the sidewall of the liquid storage component 24, which is opposite to the liquid storage shell 21, has at least one ventilation groove 242, which extends along the air outlet direction. In some embodiments, the outer sidewall of the first liquid storage component 24a may have multiple ventilation grooves 242, which may be spaced apart along the outer periphery of the first liquid storage component 24a. The first liquid storage component 24a may have four ventilation grooves 242. Of course, it is understood that in some other embodiments, the number of ventilation grooves 242 on the first liquid storage component 24a may not be limited to four, but may also be one, two, three, etc. The outer sidewall of the second liquid storage component 24b may have two ventilation grooves 242, which may correspond one-to-one with the two ventilation holes 2122 on the partition structure 212.

[0064] In some embodiments, the vent 2122 may communicate with the vent groove 242 to form at least a partial ventilation channel 20b. Specifically, the vent groove 242 and vent 2122 of the second liquid storage component 24b and the vent groove 242 of the first liquid storage component 24a communicate to form at least a partial ventilation channel 20b. In some embodiments, a gap is provided between the liquid storage component 24 and the partition structure 212, which may communicate with the vent 2122 and the vent groove 242 on the liquid storage component 24, thereby forming the at least a partial ventilation channel 20b. Generally, a support boss 2123 can be provided on the end face of the vent 2122 and the perforation 2121 to leave a gap between the liquid storage component 24 and the partition structure 212, thereby facilitating the formation of the ventilation channel 20b and promoting ventilation. In some embodiments, a gap is provided between the outer wall of the second liquid storage component 24b and the inner wall of the liquid storage shell 21 and the second partition portion 212b, and a gap is provided between the end wall of the second liquid storage component 24b facing the first partition portion 212a and the first partition portion 212a. This gap can communicate with the vent hole 2122 and the vent groove 242 to form the at least part of the venting channel 20b. In some embodiments, a gap is provided between the first liquid storage component 24a and the first end cap 22. This gap can form the part of the venting channel 20b and communicate with the airflow channel 20a, thereby achieving communication with the outside through the airflow channel 20b. The air pressure in the liquid storage chamber 213 can be balanced through the venting channel 20b, making the liquid supply from the liquid storage chamber 213 to the atomizing component 25 more unobstructed.

[0065] like Figure 13 and Figure 14 As shown, in some embodiments, the atomizing component 25 can be disposed in at least two liquid storage chambers 213. Specifically, the atomizing component 25 can be disposed in the first liquid storage chamber 213a and the second liquid storage chamber 213b. The atomizing component 25 may include an atomizing seat 251 and at least two heating structures 253. The atomizing seat 251 may be cylindrical and may have a through-hole structure at both ends. The atomizing seat 251 can be disposed in at least two liquid storage chambers 213. One end of the atomizing seat 251 may be inserted into the second air passage 231 and pass through the second liquid storage component 24b, the partition structure 212, and the first liquid storage component 24a to the first air passage 221. The at least two sets of heating structures 253 are spaced apart in the atomizing seat 251 and can form an integral structural component with the atomizing seat 251 before being installed in the liquid storage shell 21. Each set of heating structures 253 can be correspondingly arranged with a liquid storage chamber 213 and is in liquid-conducting communication with the liquid storage chamber 213 to heat the atomizing matrix delivered from the corresponding liquid storage chamber 213. Specifically, in this embodiment, there can be two sets of heating structures 253, which are installed alternately in the atomizing seat 251. One set of heating structures 253 is in fluid communication with the first liquid storage chamber 213a, and the other set of heating structures 253 is in fluid communication with the second liquid storage chamber 213b.

[0066] In some embodiments, the atomizing base 251 can be a metal tube. Of course, it is understood that in other embodiments, the atomizing base 251 is not limited to a metal tube; it can also be a ceramic tube or a glass tube. In some embodiments, a liquid inlet 2511 can be provided on the side wall of the atomizing base 251. The liquid inlet 2511 can be provided one-to-one with the heating structure 253 and communicates one-to-one with the liquid storage chamber 213, for allowing the liquid matrix in the liquid storage chamber 213 to enter the heating structure 253.

[0067] In some embodiments, one end of the atomizing seat 251 facing the first airflow hole 221 is sleeved on the outer periphery of an atomizing tube 252. The atomizing tube 252 can extend toward the first airflow hole 221, and is coaxially arranged with the atomizing seat 251 and communicates with the atomizing seat 251.

[0068] In some embodiments, each heating structure 253 may include an atomizing core 2531 and a heating element 2532. The atomizing core 2531 may be generally columnar and may have a through-end structure, and is coaxially arranged with and communicates with the atomizing seat 251 and the atomizing tube 252. The sidewall of the atomizing core 2531 may communicate with the liquid storage chamber 213 through the liquid inlet 2511. In some embodiments, there may be one heating element 2532, which is disposed on the atomizing core 2531. Specifically, the heating element 2532 may be disposed in the atomizing core 2531 and attached to the inner wall of the atomizing core 2531. In other embodiments, the heating element 2532 may not be limited to one, and there may be two. In this embodiment, the heating element 2532 may be mesh-like, which may be a metal mesh, and may be wound into a hollow columnar structure. In some embodiments, the heating element 2532 may also be sleeved on the outer periphery of the atomizing core 2531. The heating element 2532 can heat the liquid matrix on the atomizing core 2531 when it is powered on.

[0069] In some embodiments, each heating structure 253 further includes a conductive connector 2533. Each heating structure may have two conductive connectors 2533. In this embodiment, the conductive connector 2533 can be a conductive wire. Of course, it is understood that in other embodiments, the conductive connector 2533 is not limited to a conductive wire; it can also be a pin or a conductive sheet. The conductive connector 2533 can extend from the atomizing seat 251. Specifically, the conductive connectors 2533 of both heating structures 253 can extend from the end of the atomizing seat 251 toward the second end cap 23 and connect to the power supply assembly 30. In this embodiment, one conductive connector 2533 of the two heating structures 253 can be shared, so the total number of conductive connectors 2533 of the two heating structures 253 can be three. That is, the two heating structures 253 can be arranged in parallel, which is beneficial for individually heating each liquid storage chamber 213. In other embodiments, the conductive connectors 2533 of each heating structure 253 may not be shared.

[0070] In some embodiments, the atomizing assembly 25 further includes an isolation seal 254, which may be disposed between the two sets of heating structures 253. The isolation seal 254 is located between the atomizing seat 251 and the partition structure 212, and can seal at least a portion of the gap between the atomizing seat 251 and the partition structure 212, thereby preventing the liquid atomizing matrix of the two adjacent liquid storage chambers 213 from flowing into each other and affecting the taste of the aerosol, and preventing leakage.

[0071] In some embodiments, the atomizing assembly 25 further includes a wire-clamping structure 255, which is disposed in the atomizing base 251 and located at one end of the atomizing base 251 facing the second end cap 23. The wire-clamping structure 255 can be cylindrical and can be a through-structure at both ends. The wire-clamping structure 255 can be a cylindrical structure with a circular cross-section, and the outer diameter of the middle section can be larger than the outer diameter of the two ends. Part of the outer wall of the wire-clamping structure 255 can be fixed to the inner wall of the atomizing base 251 through close contact. The wire-clamping structure 255 has a through hole 2551, which can be located at the central axis of the wire-clamping structure 255, allowing external airflow to enter the atomizing assembly 25. The outer wall of the wire-clamping structure 255 can be provided with wire-clamping grooves 2552. There can be multiple wire-clamping grooves 2552, which can be spaced apart circumferentially along the wire-clamping structure 255. Each conductive connector 2533 can be clamped in one wire-clamping groove 2552. In some embodiments, there may be one wire slot 2552, in which all conductive connectors 2533 may be secured, and adjacent conductive connectors 2533 may be insulated from each other by setting an insulating structure, such as an outer insulating structure for the conductive connectors 2533.

[0072] By setting up this cable clamping structure 255, there is no need to open a separate cable routing channel, which simplifies the manufacturing process of the atomizer 20 and facilitates the miniaturization design of the atomizer 20. In addition, it makes assembly easier.

[0073] In some embodiments, the atomizer 20 further includes a liquid absorption structure 26, which may be installed on some of the second end cap 23 opposite to the liquid storage chamber 213. It may be absorbent cotton, which can absorb liquid matrix leaking from the second end cap 23. In other embodiments, the liquid absorption structure 26 may not be limited to absorbent cotton.

[0074] In some embodiments, the power supply assembly 30 may include a bracket 31 and a power supply 32. The bracket 31 may be disposed in the housing 10 and may be located at one end of the atomizer 20. The bracket 31 may support the atomizer 20 and may be locked in place with the second end cap 23. The power supply 32 may be disposed on the bracket 31 and may be connected to the conductive connector 2533.
