[0049] In some embodiments, a partition structure 212 can be provided in the liquid storage shell 21, and the partition structure 212 can be used to divide the space in the liquid storage shell 21 into at least two liquid storage cavities 213. The at least two liquid storage cavities 213 are arranged independently of each other. In some embodiments, the liquid storage cavities 213 can be two, i.e., the liquid storage shell 21 can include a first liquid storage cavity 213a and a second liquid storage cavity 213b. The partition structure 212 can divide the space in the liquid storage shell 21 into the first liquid storage cavity 213a and the second liquid storage cavity 213b.

[0050] In some embodiments, the partition structure 212 can 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 direction of the air outlet, i.e., the first partition portion 212a is parallel to the first opening 210 and transversely intersects the partial liquid storage shell 21. The second partition portion 212b can be one. The second partition portion 212b can be connected to the first partition portion 212a and can extend in a direction opposite to the direction of the air outlet. The length of the second partition portion 212b can be less than the height of the liquid storage shell 21, and the second partition portion 212b can extend towards the second opening 211 and extend to the second opening 211. In other embodiments, the second partition portion 212b can also be multiple. Multiple second partition portions 212b can be spaced apart along the circumference of the first partition portion 212a.

[0051] In some embodiments, the partition structure 212 and the liquid storage shell 21 are an integral structure, which 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 a split structure, and the two can be connected and fixed by setting a clamping structure or by interference fit.

[0052] In some embodiments, the partition structure 212 can be provided with a perforation 2121. The perforation 2121 can be provided on the first partition portion 212a and can be disposed towards the first opening 210. The perforation 2121 can be used for the atomization assembly 25 to pass through.

[0053] In some embodiments, the partition structure 212 is provided with an air exchange hole 2122. The air exchange hole 2122 can communicate with the first liquid storage cavity 213a and the second liquid storage cavity 213b. In some embodiments, the air exchange hole 2122 can be two. The two air exchange holes 2122 are spaced apart on the first partition portion 212a and located on two opposite sides of the perforation 2121.

[0054] The first liquid storage cavity 213a and the second liquid storage cavity 213b are independently and partitioned. The first liquid storage cavity 213a extends to at least one side of the second liquid storage cavity 213b. Specifically, the first liquid storage cavity 213a can be in communication with the first opening 210 and extend from the first opening 210 to the second opening 211. In some embodiments, the longitudinal section of the first liquid storage cavity 213a can be substantially in the shape of "7". The first liquid storage cavity 213a is formed between the first partition 212a and the first opening 210 and extends from the first opening 210 to the second opening 211. Specifically, the first liquid storage cavity 213a can include a first storage area 2131 and a second storage area 2132 in communication with each other. The first storage area 2131 and the second storage area 2132 can be located on two sides adjacent to the second liquid storage cavity 213b. Specifically, the first storage area 2131 can be located on the side of the second liquid storage cavity 213b facing the first opening 210, and the second storage area 2131 can be located on the side of the second liquid storage cavity 213b in the circumferential direction. Specifically, the first storage area 2131 and the second liquid storage cavity 213b are arranged side by side in 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 can be formed between the first partition 212a and the first opening 210, and the second storage area 2132 is in communication with the first storage area 2131 and is formed on one side of the second liquid storage cavity 213b. The second liquid storage cavity 213b is located close to and in communication with the second opening 211. The capacity of the first liquid storage cavity 213a can be greater than the capacity of the second liquid storage cavity 213b.

[0055] In other embodiments, the second storage area 2132 can also be located on at least two sides of the second liquid storage cavity 213b in the circumferential direction. In other embodiments, the first storage area 2131 and the second liquid storage cavity 213b can also be arranged non-coaxially in the air outlet direction, and only partially overlap in the air outlet direction. In the direction perpendicular to the air outlet direction, the second storage area 2132 can only partially overlap with the second liquid storage cavity 213b.

[0056] The first liquid storage cavity 213a can be a main liquid storage cavity, and the second liquid storage cavity 213b can be an auxiliary liquid storage cavity. The liquid matrix in the first liquid storage cavity 213a and the second liquid storage cavity 213b can be atomized at the same time. The first liquid storage cavity 213a can store a first liquid matrix, which can be a main liquid matrix, such as e-liquid, medicine liquid, etc. The first liquid matrix can generate a first aerosol when atomized. The second liquid storage cavity 213b can store a second liquid matrix, which can be a flavoring substance. The second aerosol generated by the second liquid matrix can be mixed with the first aerosol generated by the first liquid matrix to form a third aerosol, which has a taste and / or flavor different from the first aerosol.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] In some embodiments, the first liquid storage member 24a is substantially in the shape of a "7", and can include a first liquid storage portion 241a and a second liquid storage portion 242a. The first liquid storage portion 241a can be disposed in the first storage area 2131, and the second liquid storage portion 242a can be disposed in the second storage area 2132. The first liquid storage portion 241a can be connected to the second liquid storage portion 242a, and the two can be disposed at a right angle, and can be integrally formed. The first liquid storage portion 241a and the second liquid storage portion 242a are in fluid communication, and liquid substrate can be transported from the second liquid storage portion 242a to the first liquid storage portion 241a. By 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, the first liquid storage member 24a can be facilitated to be installed, 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 can be understood that in other embodiments, the first liquid storage portion 241a and the second liquid storage portion 242a can not be limited to be disposed at a right angle.

[0062] In some embodiments, the second liquid storage cavity 213b can be provided with a second liquid storage member 24b, and the second liquid storage member 24b is substantially in the shape of a square. The shape and size of the second liquid storage member 24b are adapted to the shape and size of the second liquid storage cavity 213b.

[0063] In some embodiments, the liquid storage member 24 can be made of any suitable material or combination of materials capable of transporting liquid aerosol-forming substrate towards the atomization device. It can be a capillary material, which can include a sponge or foam material, a ceramic-based or graphite-based material in the form of a fiber or sintered powder, a foam metal or plastic material, a fibrous material (e.g. made of spun or pressed fibers such as cellulose acetate fibers, polyester fibers, bonded polyolefin fibers, polyethylene fibers, terylene fibers or polypropylene fibers, nylon fibers) or ceramic. The capillary can have any suitable capillarity for use with different liquid physical properties.

[0064] The capillary material can comprise a material which is inherently porous, such as a ceramic material such as alumina (corundum). Alternatively, the porous material can comprise a material having a plurality of manufactured micro-pores to allow migration of the liquid aerosol-forming substrate to the atomisation device. The porous material can comprise a hydrophilic material to improve the distribution and spreading of the liquid aerosol-forming substrate. The material or materials which are particularly preferred will depend on the physical properties of the liquid aerosol-forming substrate. Examples of suitable materials are capillary materials such as a sponge or foam material, a ceramic-based or graphite-based material in the form of a fibrous or sintered powder, a foam metal or a plastics material, a fibrous material (for example made from spun fibres or carded fibres (for example cellulose acetate fibres, polyester fibres, bonded polyolefin fibres, polyethylene fibres, terylene fibres or polypropylene fibres, nylon fibres) or a ceramic. The porous material can have any suitable porosity for use with different liquid physical properties.

[0065] In other embodiments, the liquid storage member 24 can also have other materials of capillary channels, such as silica gel, plastic, stainless steel, glass, etc.

[0066] In some embodiments, the density of the second liquid storage portion 242a of the first liquid storage member 24a can be less than the density of the first liquid storage portion 241a, thereby reducing the liquid substrate residue of the first liquid storage member 24a and improving the utilization rate of the liquid substrate in the first liquid storage member 24a.

[0067] In some embodiments, the liquid storage member 24 can be provided with a through hole 241 coaxially arranged with the first airflow through hole 221. Specifically, each liquid storage member 24 is provided with a through hole 241, which can be arranged through the thickness direction of the liquid storage member 24. The first liquid storage member 24a can be provided with the through hole 241 on the first liquid storage portion 241a, and the through hole 241 of the second liquid storage member 24b can be coaxially arranged with the through hole 241 of the first liquid storage member 24a. The through hole 241 can be penetrated by the atomization assembly 25.

[0068] In some embodiments, the side wall of the liquid storage member 24 opposite to the liquid storage shell 21 is provided with at least one air exchange groove 242, which can extend in the air outlet direction. In some embodiments, the outer side wall of the first liquid storage member 24a can be provided with a plurality of air exchange grooves 242, which can be arranged at intervals along the outer periphery of the first liquid storage member 24a. The first liquid storage member 24a can be provided with four air exchange grooves 242, of course, it can be understood that in other embodiments, the air exchange grooves 242 on the first liquid storage member 24a can not be limited to four, but can also be one, two, three, etc. The outer side wall of the second liquid storage member 24b can be provided with two air exchange grooves 242, which can be arranged one by one with the two air exchange holes 2122 on the partition structure 212.

[0069] 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.

[0070] 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.
