Common reference numerals are used throughout the drawings and the detailed description to refer to the same or like components. The features of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

Detailed Description

The following disclosure provides many different embodiments, or examples, for implementing different features of the provided subject matter. Specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to be limiting. In the present application, references in the following description to the formation of a first feature over or on a second feature may include embodiments in which the first feature is formed in direct contact with the second feature, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present application may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Embodiments of the present application are discussed in detail below. It should be appreciated, however, that the present application provides many applicable concepts that can be embodied in a wide variety of specific contexts. The particular embodiments discussed are merely illustrative and do not limit the scope of the application. As used herein, the term "aerosol for inhalation by a user" can include, but is not limited to, aerosols, suspended liquids, cryogenic vapors, and volatile gases.

Existing electronic cigarette products do not take into account the pressure balance of the oil reservoir. In existing electronic cigarette products, the oil reservoir is typically designed to be completely sealed to prevent the escape of the vaporizable solution. In the transportation process of the manufactured electronic cigarette product, the pressure in the oil storage chamber may rise due to temperature change or air pressure change. The pressure rise in the reservoir will cause a significant amount of tobacco smoke to flow towards the aerosol generating assembly and can cause problems with the leakage of tobacco smoke from the electronic cigarette product. In addition, as the user continues to use the electronic cigarette product, the vaporizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber is reduced to form negative pressure. The negative pressure makes it difficult for the vaporizable solution in the oil storage chamber to uniformly flow onto the aerosol generating component, so that the aerosol generating component does not uniformly adsorb the vaporizable solution. In this case, the aerosol generating assembly will have a high probability of being burnt without heating when the temperature rises, resulting in a scorched smell, which is a bad user experience.

The atomization device 100 may include a cartridge (cartridge)100A and a body 100B. In certain embodiments, the cartridge 100A and the body 100B may be designed as one piece. In certain embodiments, the cartridge 100A and the body 100B may be designed as two separate components. In certain embodiments, the cartridge 100A may be designed to be removably coupled to the body 100B. In certain embodiments, when the cartridge 100A is joined with the body 100B, a portion of the cartridge 100A is received in the body 100B. In certain embodiments, the cartridge 100A may be referred to as an oil reservoir assembly and the body 100B may be referred to as a main body (main body) or a battery assembly.

The cartridge 100A has an opening 1h1 at the top. Opening 1h1 may serve as an aerosol outlet. The user can inhale the aerosol generated by the atomizing device 100 through the opening 1h 1. The body 100B and the cartridge 100A may be coupled to each other via conductive contacts (not shown). When a user inhales on the opening 1h1, the main body 100B may provide power to the cartridge 100A causing the aerosol-generating component of the cartridge 100A to heat the nebulizable material stored in the cartridge 100A and generate an aerosol.

The main body 100B has a main body housing 22. The main body case 22 has an opening 22 h. The opening 22h may receive a portion of the cartridge 100A.

In some embodiments, the mouthpiece cover 1b and the cartridge housing 1 may be made of different materials. In certain embodiments, the mouthpiece cover 1b and the cartridge housing 1 may be integrally formed. In some embodiments, the mouthpiece cover 1b and the cartridge housing 1 may be made of the same material.

The cartridge 100A further comprises an upper lid 2, an aerosol-generating component 3, a lower lid 4, and adsorbing

components

5a and 5 b. In the present disclosure, the upper lid 2 and the lower lid 4 may be referred to as a base. When the upper and

lower covers

2, 4 are assembled together, it may be referred to as the base of the cartridge 100A. The upper cover 2 and the lower cover 4 may be regarded as an atomizing assembly.

The mouthpiece cover 1b has an opening 1h1 at the top. Opening 1h1 may serve as an aerosol outlet. The user can inhale the aerosol generated by the atomizing device 100 through the opening 1h 1. The opening 1h1 communicates with a tube 1t extending into the cartridge housing 1, the tube 1t being capable of delivering the aerosol generated by the aerosol-generating assembly 3 to the opening 1h1 for inhalation by a user.

The cartridge housing 1 has openings 1h2 and 1h3 near the bottom. Openings 1h2 and 1h3 may correspond to snap structures (buckle structures) 4b1 and 4b2, respectively, on lower cover 4. Via opening 1h2, opening 1h3, catch structure 4b1 and catch structure 4b2, cartridge housing 1 can be mechanically coupled with lower cover 4.

The bottom of the aerosol-generating component 3 may contain a heating element 31, and by supplying power to the heating element 31, the heating element 31 may increase the temperature of the aerosol-generating component 3, and atomize the tobacco tar adsorbed by the aerosol-generating component 3 to generate aerosol. The aerosol-generating component 3 may comprise a slot 3c, and the nebulizable material may be in direct contact with the aerosol-generating component 3 via the inner wall of the slot 3 c. The nebulizable material may be a liquid. The nebulizable material may be a solution. In subsequent paragraphs of this application, the nebulizable material may also be referred to as tobacco tar. The tobacco tar is edible.

In some embodiments, the aerosol-generating assembly 3 may be an infrared assembly that heats the tobacco tar. In some embodiments, the aerosol-generating assembly 3 may be an ultrasonic assembly that heats the tobacco tar. In certain embodiments, the aerosol-generating component 3 may be an infrared component that heats the solid tobacco. In some embodiments, the aerosol-generating member 3 may be an ultrasonic member that heats the solid tobacco.

The bottom cover 4 may include pillar structures 4p1 and 4p 2. When the cartridge 100A is assembled, the pillar structures 4p1 and 4p2 may extend into the interior of the lid 2.

The

adsorption elements

5a and 5b may be disposed in the openings 4h1 and 4h2, respectively, at the bottom of the lower cover 4. In some embodiments, the

sorption elements

5a and 5b may be electrically conductive. The body 100B may transmit power to the aerosol-generating component 3 in the cartridge 100A via the adsorbent components 5a and 5B. In some embodiments, the

attraction components

5a and 5b may be magnetic. The adsorption members 5a and 5B can adsorb the metal contacts and/or the conductive contacts disposed in the main body 100B. The adsorbent elements 5a and 5B may make the cartridge 100A less likely to loosen from the body 100B when the cartridge 100A and the body 100B are coupled to each other.

The upper cover 2 may include a top sealing structure 2t, a body 2m, and a bottom sealing structure 2 b. In certain embodiments, the top sealing structure 2t and the body 2m may have different hardnesses. In some embodiments, the bottom sealing structure 2b and the body 2m may have different hardness. In certain embodiments, the top sealing structure 2t and the body 2m may comprise different materials. In some embodiments, the bottom sealing structure 2b and the body 2m may comprise different materials. In certain embodiments, the hardness of the top sealing structure 2t may be less than the hardness of the body 2 m. In certain embodiments, the hardness of the bottom sealing structure 2b may be less than the hardness of the body 2 m.

The top seal structure 2t may have elasticity. The tip seal structure 2t may have flexibility. The bottom sealing structure 2b may have elasticity. The bottom sealing structure 2b may have flexibility.

The material of the main body 2m may be a rigid plastic, such as polypropylene (PP) or Polyethylene (PE), but other suitable materials may be selected according to actual circumstances, and is not limited thereto. The material of the top sealing structure 2t may be silica gel, rubber, or siloxane, but other suitable materials may be selected according to actual circumstances, and is not limited thereto. The material of the bottom sealing structure 2b may be silica gel, rubber, or siloxane, but other suitable materials may be selected according to actual circumstances, and is not limited thereto. The top seal 2t and the bottom seal 2b provide a liquid or gas seal when the upper lid 2 is assembled with the cartridge housing 1.

The top sealing structure 2t, the main body 2m, and the bottom sealing structure 2b may be formed by integral injection molding. The upper cover 2 may be formed by integral injection molding.

The bonding force between the top sealing structure 2t or the bottom sealing structure 2b and the main body 2m is 0.1N/cm²(Newton/mm square) to 20N/cm²Within the range of (1). In certain embodiments, the user cannot separate the top seal 2t from the body 2m without compromising the structural integrity of the top seal 2t or the body 2 m. In certain embodiments, the user cannot separate the bottom seal 2b from the body 2m without compromising the structural integrity of the bottom seal 2b or the body 2 m.

Because the top sealing structure 2t or the bottom sealing structure 2b and the main body 2m can be formed in an integrated injection molding mode, the problems of assembly deviation and part tolerance do not exist, and the leakage of smoke oil or condensed liquid can be reduced. Because the upper cover 2 can be formed by an integrated injection molding mode, the upper cover 2 has no problems of assembly deviation and part tolerance, and the leakage risk of smoke oil or condensed liquid can be reduced.

Because the top sealing structure 2t or the bottom sealing structure 2b and the main body 2m can be integrally formed into a single component in an injection molding mode, the number of components of the cartridge 100A can be reduced, and the difficulty in producing the cartridge 100A can be reduced. Because the upper cover 2 is a single component, the number of components of the cartridge 100A can be reduced and the production/assembly efficiency of the cartridge 100A can be improved.

The top seal structure 2t includes valve structures 2v1 and 2v 2. The detailed construction and function of the valve structures 2v1 and 2v2 will be explained in subsequent paragraphs of the present application. The valve structures 2v1 and 2v2 may also be referred to as switches in this application. The valve structures 2v1 and 2v2 may also be referred to as switch structures in this application.

When the upper cover 2 is assembled with the cartridge 100A, the protruding structure 2t1 can be located on the outer surface of the upper cover 2 and abut between the tube 1t inside the cartridge 100A and the tubular structure 2m1 of the upper cover 2, providing a sealing effect between the tube 1t and the tubular structure 2m 1. When the upper lid 2 is assembled with the cartridge 100A, a portion of the tube 1t (i.e., the portion 1t2) may extend into the tubular structure 2m 1. In this case, the boss 2t2 can provide a sealing effect between the tube 1t and the tubular structure 2m 1.

When the upper cover 2 is assembled with the cartridge 100A, the protrusion 2t3 may abut against the inner wall of the cartridge case 1, thereby providing a sealing effect between the upper cover 2 and the cartridge case 1. When the upper cover 2 is assembled with the aerosol-generating component 3, the aerosol-generating component seal 2t4 may abut around the top of the aerosol-generating component 3, thereby providing a sealing effect between the upper cover 2 and the aerosol-generating component 3.

As shown in fig. 3B, the bottom sealing structure 2B includes a boss 2B1 and an overhang structure 2B 2.

When the upper cover 2 is assembled with the cartridge 100A, the protrusion 2b1 may abut against the inner wall of the cartridge housing 1, thereby providing a sealing effect between the upper cover 2 and the cartridge housing 1.

When the upper cover 2 and the lower cover 4 are assembled, the protruding structure 2b2 can abut between the upper cover 2 and the lower cover 4, thereby providing a sealing effect between the upper cover 2 and the lower cover 4.

In some embodiments, the number of second vias 402 may be less than 5.

The aperture size of the first through-hole 401 may be larger than the aperture size of the second through-hole 402. In some embodiments, the aperture size of the first through-hole 401 may be in the range of 0.55mm to 0.75 mm. In some embodiments, the first through-hole 401 has an aperture size of about 0.65 mm. In certain embodiments, the pore size of the second through-hole 402 may be in the range of 0.40mm to 0.50 mm. In some embodiments, the second via 402 has an aperture size of about 0.46 mm.

In certain embodiments, the first through-hole 401 of the air inlet hole 4f may be aligned with the geometric center of the bottom surface of the aerosol-generating assembly 3 when the cartridge 100A is assembled. According to the software simulation experiment result, the first through holes 401 with larger hole diameters can enable fresh air to more uniformly blow the heating element 31 at the bottom of the aerosol generating component 3, and the aerosol generating efficiency of the aerosol generating component 3 is improved.

In a direction perpendicular to the bottom surface of the aerosol-generating assembly 3, the first through holes 401 are located below the aerosol-generating assembly 3 and substantially correspond to the center of the aerosol-generating assembly 3, and the second through holes 402 are located within the projection range of the aerosol-generating assembly 3.

Refer to fig. 6C and 6D. The contact structure 62 completely covers the opening 4h1, and the contact structure 64 completely covers the opening 4h 2. The contact structure 62 can prevent the smoke or condensed liquid inside the cartridge 100A from leaking from the opening 4h1 to the outside of the cartridge 100A. The contact structure 64 can prevent the smoke or condensed liquid inside the cartridge 100A from leaking from the opening 4h2 to the outside of the cartridge 100A.

When the cartridge 100A is assembled, the distance of the upper surface 4s of the air inlet 4f from the bottom of the aerosol-generating assembly 3 may be in the range 1.5mm to 3.5 mm. In certain embodiments, the distance of the upper surface 4s of the air inlet 4f from the bottom of the aerosol-generating assembly 3 may be in the range 2mm to 3 mm. Software simulation results show that the above-described distance setting can improve the aerosol generation efficiency of the aerosol-generating assembly 3. The above distance arrangement can improve the amount of gas mist generation in the gas mist generating module 3.

Fig. 6E demonstrates a schematic top surface view of a lower cover according to some embodiments of the present application. The air inlet holes 4f are disposed between the pillar structures 4p1 and 4p 2. The intake hole 4f includes a first through hole 401 and a plurality of second through holes 402 surrounding the first through hole 401. The elastic sheet structure 61 and the elastic sheet structure 63 are respectively disposed on two sides of the air inlet 4 f. The elastic sheet structure 61 is disposed between the air inlet hole 4f and the cylindrical structure 4p 1. The elastic sheet structure 63 is disposed between the air inlet hole 4f and the cylindrical structure 4p 2.

In fig. 7A, 3 components within the cartridge 100A are shown. In fig. 7A cross-sectional view of the cartridge housing 1, the upper lid 2, and the lower lid 4 is shown.

The cartridge housing 1 contains a tube 1t extending towards the upper lid 2. Tube 1t may include a first portion 1t1 and a second portion 1t 2. The first portion 1t1 and the second portion 1t2 may have different outer diameters. In certain embodiments, the outer diameter of the first portion 1t1 is greater than the outer diameter of the second portion 1t 2. The smaller outer diameter of the second portion 1t2 makes it easier to insert the tube 1t into the tubular structure 2m1 of the upper cap 2.

The tube 1t may have a non-uniform inner diameter. In certain embodiments, the inner diameter of the tube 1t may have a step difference 1s between the first portion 1t1 and the second portion 1t 2. The step 1s may also be referred to as a step structure. As shown in fig. 7A, the first portion 1t1 has an inner diameter 1w1 adjacent to the second portion 1t2, and the second portion 1t2 has an inner diameter 1w2 adjacent to the first portion 1t 1. Inner diameter 1w1 is different from inner diameter 1w 2. In certain embodiments, inner diameter 1w2 is less than inner diameter 1w 1.

When the aerosol generated by the aerosol-generating assembly 3 passes along the tube 1t toward the opening 1h1, it passes through the step 1 s. After the gas mist passes through the step difference 1s, the inner diameter of the pipe 1t is enlarged (from 1w2 to 1w1), so that the probability that the gas mist is condensed on the inner wall of the pipe 1t to generate condensed liquid can be reduced. The step difference 1s can reduce the amount of condensed liquid generated during the use of the cartridge 100A, thereby reducing the probability of leakage of the condensed liquid during the use.

In some embodiments, the inner diameter of the tube 1t has a smaller inner diameter at a portion close to the upper cap 2 and a larger inner diameter at a portion distant from the upper cap 2. In certain embodiments, the inner diameter of the tube 1t has a smaller inner diameter at a portion proximal to the aerosol-generating assembly 3 and a larger inner diameter at a portion distal to the aerosol-generating assembly 3.

The inner wall of the cartridge housing 1 further comprises a stepped structure 1 d. The stepped structure 1d may be formed by a non-uniform thickness of the cartridge housing 1. The stepped structure 1d may be formed by the inner surfaces 1ds1 and 1ds2 of the cartridge housing 1. The inner surface 1ds1 of cartridge housing 1 may be non-coplanar with the inner surface 1ds2 of cartridge housing 1 (coplanar). There may be a step difference between the inner surface 1ds1 of the cartridge housing 1 and the inner surface 1ds2 of the cartridge housing 1. The stepped structure 1d may provide resistance between the cartridge housing 1 and the upper cover 2 during assembly of the cartridge 100A. When the top sealing structure 2t of the upper lid 2 reaches a predetermined position after abutting against the stepped structure 1d, and a force is continuously applied to the lower lid 4 toward the upper lid 2, the thin protrusion 4d1 and the thin protrusion 4d3 of the pillar structure 4p1 are deformed, and the pillar structure 4p1 is inserted and fixed into the upper lid 2. Similarly, the two thin protrusions of the pillar structure 4p2 are deformed, so that the pillar structure 4p2 is inserted into and fixed in the upper lid 2.

Figure 7B demonstrates a cross-sectional view of a cartridge according to some embodiments of the present application. Figure 7B illustrates a cross-sectional view of the cartridge 100A.

As shown in fig. 7B, when the cartridge 100A is assembled, the overhang structure 2t1 of the top seal structure 2t may abut between the tube 1t and the tubular structure 2m1, providing a sealing effect between the tube 1t and the tubular structure 2m 1. The overhanging structure 2t1 may be provided on the upper surface of the tubular structure 2m 1. The overhang structure 2t1 may be disposed between the upper surface of the tubular structure 2m1 and the step structure 1d2 (see fig. 7A) of the tube 1 t.

When the cartridge 100A is assembled, a portion of the tube 1t (i.e., the portion 1t2) may extend into the tubular structure 2m 1. In this case, the boss 2t2 of the top sealing structure 2t may provide a sealing effect between the tube 1t and the tubular structure 2m 1.

The storage compartment 10 is defined between the top sealing structure 2t, the tube 1t and the inner surface 1s2 of the cartridge housing 1. The storage compartment 10 may contain tobacco tar. When the cartridge 100A is assembled, the boss 2t3 of the top seal 2t may abut against the inner surface 1s1 of the cartridge housing 1, thereby providing a sealing effect between the upper cover 2 and the cartridge housing 1. When the cartridge 100A is assembled, the aerosol-generating assembly seal 2t4 of the top sealing structure 2t may abut around the top of the aerosol-generating assembly 3, thereby providing a sealing effect between the upper lid 2 and the aerosol-generating assembly 3. The aerosol-generating assembly seal 2t4 may surround the slot 3c of the aerosol-generating assembly 3.

When the cartridge 100A is assembled, the boss 2b1 of the bottom seal 2b may abut against the inner surface 1s1 of the cartridge housing 1, thereby providing a sealing effect between the upper lid 2 and the cartridge housing 1.

When upper cover 2 and lower cover 4 are assembled, overhang structure 2b2 of bottom seal structure 2b can abut between surfaces 4s1 of upper cover 2 and lower cover 4, thereby providing a sealing effect between upper cover 2 and lower cover 4.

When the cartridge 100A is assembled, the distance of the upper surface 4s of the air inlet 4f from the bottom surface 3s of the aerosol-generating assembly 3 may be in the range 1.5mm to 3.5 mm. In certain embodiments, the distance of the upper surface 4s of the air inlet 4f from the bottom surface 3s of the aerosol-generating assembly 3 may be in the range 2mm to 3 mm.

Figure 8 demonstrates an assembly schematic of a cartridge according to some embodiments of the present application. Figure 8 demonstrates the relative positions of the upper and

lower caps

2, 4 after the cartridge 100A has been assembled in the first stage. For the sake of simplicity of description, drawing of the adsorption unit 5a and the adsorption unit 5b is omitted in fig. 8. The above components should be included in the actual assembly of the cartridge 100A.

As shown in fig. 8, the lower cover 4 and the upper cover 2 are assembled in a first stage, so that the lower cover 4 and the upper cover 2 become a single assembly 24 connected to each other. The single package 24 is not easily separated into the lower cover 4 and the upper cover 2 during transportation or movement.

The upper cover 2 has

windows

201 and 202 on both sides. In the first stage of assembly of the lower cap 4 with the upper cap 2, a force is applied to the bottom of the lower cap 4 in a direction toward the upper cap 2, so that the pillar-like structure 4p1 is inserted deeply into the upper cap 2. The force applied to the lower cover 4 may cause the snap tabs 4d2 and 4d4 of the pillar structures 4p1 to reach into the

windows

201 and 202, respectively.

The snap tabs 4d2 may include

inclined surfaces

421 and 422 to facilitate the ability of the pillar structures 4p1 to pass the bottom edge 2e1 and penetrate into the top cover 2. The snap tabs 4d4 may include

inclined surfaces

441 and 442 to facilitate the ability of the pillar structures 4p1 to pass through the bottom edge 2e2 and penetrate into the top cover 2.

When the catching protrusion 4d2 reaches the window 201, the thin protrusion 4d1 of the pillar structure 4p1 abuts against the bottom edge 2e1 of the upper cover 2, and the catching protrusion 4d2 of the pillar structure 4p1 abuts against the surface 201s of the window 201. Similarly, when the snap projection 4d4 reaches the window 202, the thin projection 4d3 of the pillar structure 4p1 abuts against the bottom edge 2e2 of the upper lid 2, and the snap projection 4d4 of the pillar structure 4p1 abuts against the surface 202s of the window 202. After the first stage assembly, the lower cover 4 and the upper cover 2 become the single assembly 24 connected to each other, which facilitates the second stage assembly after all the components of the cartridge 100A are transported to the destination.

As shown in fig. 8, after the first stage assembly, the pillar structure 4p1 has not yet fully penetrated into the valve structure 2v1, so that a gap for allowing fluid to pass through is still maintained between the pillar structure 4p1 and the valve structure 2v 1.

The thin protrusion 4d1 may have a thickness of 4w 1. In certain embodiments, the thickness 4w1 may be in the range of 0.35mm to 0.65 mm. In certain embodiments, the thickness 4w1 may be in the range of 0.38mm to 0.41 mm. The thin protrusion 4d3 may have the same thickness as the thin protrusion 4d 1.

Figure 9A demonstrates an assembly schematic of a cartridge according to some embodiments of the present application. Figure 9A demonstrates a schematic of a second stage assembly of the cartridge 100A.

Figure 9A shows the lower lid 4, the upper lid 2 and the cartridge housing 1. Note that, for the sake of simplicity of description, the drawing of the aerosol-generating module 3, the adsorption module 5a, and the adsorption module 5b is omitted in fig. 9A. The above components should be included in the actual assembly of the cartridge 100A.

As described in the related paragraph with reference to fig. 8, the lower cover 4 and the upper cover 2 are assembled in the first stage, so that the lower cover 4 and the upper cover 2 are connected to each other as a single component 24, which is convenient for transportation to the destination and then assembled in the second stage.

As shown in fig. 9A, in the second stage of assembly, the cartridge case 1 is already filled with the tobacco tar 100l, and then a part of the single component 24 is pushed into the cartridge case 1, so that the single component 24 and the cartridge case 1 are fixed to each other. There is a gap/passage between the valve structure 2v1 of the upper lid 2 and the cylindrical structure 4p1 of the lower lid 4 when the mono-component 24 and the cartridge housing 1 are not yet fixed to each other. During the assembly of the single assembly 24 with the cartridge housing 1, the passage existing between the valve structure 2v1 and the cylindrical structure 4p1 allows the gas inside the cartridge housing 1 to escape along the path 2f1, avoiding excessive internal pressure after the cartridge 100A has been assembled. Similarly, the presence of the passage between the valve structure 2v2 and the cylindrical structure 4p2 allows the gas inside the cartridge housing 1 to escape along the path 2f2, avoiding excessive internal pressure after the cartridge 100A has been assembled. Excessive pressure within the cartridge 100A may cause tobacco tar to leak, reduce product yield, and may also cause a poor user experience.

Referring to both fig. 8 and 9A, the thin protrusion 4d1 and the thin protrusion 4d3 of the pillar structure 4p1 also play an important role in the second stage assembly of the cartridge 100A. During the second stage of assembly, the lower lid 4 may be continuously forced in a direction towards the cartridge housing 1 until the top sealing structure 2t of the upper lid 2 abuts against the step structure 1d (see fig. 7A) in the cartridge housing 1.

During the time that the lower lid 4 is continuously being forced, the thin protrusion 4d1 may transmit the force to the upper lid 2 via the bottom edge 2e1 of the upper lid 2 to ensure that the upper lid 2 can reach a predetermined position within the cartridge housing 1. Likewise, the thin tab 4d3 may transmit a force to the upper lid 2 via the bottom edge 2e2 of the upper lid 2 during the second stage assembly to ensure that the upper lid 2 can reach a predetermined position within the cartridge housing 1.

Figure 9B demonstrates a cross-sectional view of a cartridge according to some embodiments of the present application. Figure 9B illustrates a cross-sectional view of the cartridge 100A after assembly. Note that, for the sake of simplicity of explanation, the drawing of the metal structure 6a, the metal structure 6B, the adsorption component 5a, and the adsorption component 5B is omitted in fig. 9B. The cartridge 100A should include the above components after assembly.

As shown in fig. 9B, after the lower cover 4 and the upper cover 2 are fixed at predetermined positions in the cartridge case 1, the valve structure 2v1 is tightly attached to the pillar structure 4p1, and the valve structure 2v2 is tightly attached to the pillar structure 4p 2. The valve structure 2v1 surrounds a portion of the columnar structure 4p1 and exposes the top surface 4p1s of the columnar structure 4p 1. The valve structure 2v2 surrounds a portion of the columnar structure 4p2 and exposes the top surface 4p2s of the columnar structure 4p 2.

When the cartridge 100A is assembled, the valve structure 2v1 becomes a one-way ventilation valve. When the cartridge 100A is assembled, the valve structure 2v1 can function as both a check valve and a ventilation valve.

When the cartridge 100A is assembled, the pressure in the storage chamber 10 may be slightly greater than the pressure in the atomizing chamber 40, and the pressure in the storage chamber 10 may make the elastic structure 2p1 fit the pillar structure 4p1, or make the elastic structure 2p1 move toward the pillar structure 4p 1. Similarly, the pressure in the storage compartment 10 may cause the elastic structure 2p2 to adhere to the pillar structure 4p2, or cause the elastic structure 2p2 to move toward the pillar structure 4p 2.

As a one-way valve, the valve structure 2v1 can prevent the smoke in the storage chamber 10 from leaking out of the storage chamber 10 from between the valve structure 2v1 and the columnar structure 4p 1. As a one-way valve, the valve structure 2v2 can prevent the smoke in the storage chamber 10 from leaking out of the storage chamber 10 from between the valve structure 2v2 and the columnar structure 4p 2.

After the user continues to use the cartridge 100A, the volume of tobacco tar in the storage compartment 10 decreases and causes the pressure within the storage compartment 10 to decrease. The reduced pressure within the reservoir 10 may make it less likely that the tobacco smoke will flow towards the aerosol-generating assembly 3. The reduced pressure in the storage compartment 10 may cause the autoclave assembly 3 to fail to adequately adsorb the tobacco tar, thereby producing a scorched or bitter taste during heating.

When the pressure in the storage chamber 10 and the pressure difference in the atomization chamber 40 reach the threshold value, the air in the atomization chamber 40 can push the elastic structure 2p1 of the valve structure 2v1 away from the storage chamber 10 through the path 4f1, thereby equalizing the pressures in the storage chamber 10 and the atomization chamber 40. When the pressure difference between the pressure in the storage chamber 10 and the pressure in the atomizing chamber 40 reaches a threshold value, the air in the atomizing chamber 40 pushes away the elastic structure 2p1, so that the elastic structure 2p1 moves away from the pillar-shaped structure 4p 1. The air in the atomizing chamber 40 can deform the elastic structure 2p1 without contacting the columnar structure 4p 1.

Similarly, when the pressure in the storage chamber 10 and the pressure difference in the atomization chamber 40 reach the threshold value, the air in the atomization chamber 40 can push the elastic structure 2p2 of the valve structure 2v2 away through the path 4f2 and enter the storage chamber 10, thereby balancing the pressures in the storage chamber 10 and the atomization chamber 40. The air in the atomizing chamber 40 pushes away the elastic structure 2p2, so that the elastic structure 2p2 moves away from the columnar structure 4p 2. The air in the atomizing chamber 40 can deform the elastic structure 2p2 without contacting the columnar structure 4p 2.

As a ventilation valve, the valve structure 2v1 can reduce the possibility of dry burning when the cartridge 100A is heated, and is helpful for the user to fully use the tobacco tar in the storage chamber 10. As a ventilation valve, the valve structure 2v2 can reduce the possibility of dry burning when the cartridge 100A is heated, and is helpful for the user to fully use the tobacco tar in the storage chamber 10.

Figure 9C demonstrates a cross-sectional view of a cartridge according to some embodiments of the present application. Figure 9C demonstrates a cross-sectional view of the cartridge 100A including the upper lid 2' after assembly is complete. Note that, for the sake of simplicity of explanation, the drawing of the metal structure 6a, the metal structure 6b, the adsorption component 5a, and the adsorption component 5b is omitted in fig. 9C. The cartridge 100A should include the above components after assembly.

After the lower cover 4 and the upper cover 2 'are fixed at predetermined positions in the cartridge case 1, the valve structure 2v1' is tightly attached to the pillar structure 4p 2. When the cartridge 100A is assembled, the valve structure 2v1' becomes a one-way ventilation valve. After the user continues to use the cartridge 100A, the volume of tobacco tar in the storage compartment 10 decreases and causes the pressure within the storage compartment 10 to decrease. When the pressure in the storage chamber 10 and the pressure difference in the atomizing chamber 40 reach the threshold value, the air in the atomizing chamber 40 can push the elastic structure 2p1' of the valve structure 2v1' away through the path 4f1' and enter the storage chamber 10, thereby balancing the pressures in the storage chamber 10 and the atomizing chamber 40. As a ventilation valve, the valve structure 2v1' can reduce the possibility of dry burning when the cartridge 100A is heated, and is helpful for the user to fully use the tobacco tar in the storage compartment 10. As a one-way valve, valve structure 2v1 'prevents the smoke from within storage compartment 10 from leaking out of storage compartment 10 from between valve structure 2v1' and columnar structure 4p 2.

As shown in fig. 9C, the upper cover 2 'includes a valve structure 2v1' only on one side, and a cavity 2C on the other side. The cavity 2c can accommodate the columnar structure 4p1 of the lower cover 4. The inclusion of only a single valve structure 2v1 'can reduce the cost of manufacturing the upper cover 2'. The inclusion of only a single valve structure 2v1 'may reduce the manufacturing difficulty of the upper cover 2'. The inclusion of only a single valve structure 2v1 'may improve the yield of the upper lid 2'.

Fig. 9D illustrates a cross-sectional view of an upper cover and a lower cover according to some embodiments of the present application. Figure 9D shows the relative positions of the upper and

lower caps

2, 4 after the cartridge 100A has been assembled in the second stage. For simplicity of illustration, drawing of the cartridge housing 1 is omitted from fig. 9D.

When lower lid 4 reaches the default position in upper lid 2, thin projection 4d1 and thin projection 4d3 will deform due to the squeezing. As shown in fig. 9D, thin projection 4D1 becomes projection 4D1' when reaching the default position in upper lid 2, and abuts against inside surface 2s1 of upper lid 2. The thin projection 4d3 becomes a projection 4d3' when reaching a default position in the upper lid 2, and abuts against the inner side surface 2s2 of the upper lid 2.

The inclined surface 421 and the extending direction of the pillar structure 4p1 may include an angle θ₄₂₁The extending directions of the inclined surface 422 and the pillar structure 4p1 may include an angle θ₄₂₂. In some embodiments, the included angle θ₄₂₁May form an angle theta with₄₂₂The same is true. In some embodiments, the included angle θ₄₂₁May form an angle theta with₄₂₂Different. In some embodiments, the included angle θ₄₂₁May be in the range of 10 ° to 25 °. In some embodiments, the included angle θ₄₂₂May be in the range of 15 ° to 20 °.

The inclined surface 441 and the extending direction of the pillar-shaped structure 4p1 may include an angle θ₄₄₁The extending directions of the inclined surface 442 and the pillar structure 4p1 may include an included angle θ₄₂₂. In some embodiments, the included angle θ₄₂₁May form an angle theta with₄₂₂The same is true. In some embodiments, the included angle θ₄₂₁May form an angle theta with₄₂₂Different. In some embodiments, the included angle θ₄₂₁May be in the range of 10 ° to 25 °. In some embodiments, the included angle θ₄₂₂May be in the range of 15 ° to 20 °.

When the cartridge 100A completes the second stage assembly, the post structure 4p1 and the valve structure 2v1 contact each other. When the cartridge 100A completes the second stage assembly, the valve structure 2v1 surrounds and contacts the periphery of the cylindrical structure 4p 1. The valve structure 2v1 has a one-way ventilation function when the cartridge 100A is assembled in the second stage.

Figure 10A shows a side view of the aerosol-generating assembly 3 and the metal structure 6 a.

The metal structure 6A and the lower cover 4 are formed by integral injection molding (see fig. 6A), so that the metal structure 6A is embedded in the lower cover 4. During assembly of the cartridge 100A, the metal structure 6a will be in contact with the bottom of the aerosol-generating assembly 3 as the lower cover 4 is disposed in the cartridge housing 1. In order to more clearly describe the relative relationship of the aerosol-generating assembly 3 and the metal structure 6a, the lower cover 4 is omitted from figure 10A.

The spring structure 61 of the metal structure 6a may comprise several parts. The spring structure 61 may comprise several parts connected to each other. The spring structure 61 may comprise several segments connected to each other. As shown in fig. 10A, the dome structure 61 may include a section 61s1, a section 61s2, a section 61s3, and a section 61s 4.

Section 61s1 and section 61s2 are connected to each other. Section 61s2 and section 61s3 are connected to each other. Section 61s3 and section 61s4 are connected to each other. The junction of section 61s3 and section 61s4 includes a junction 61t 1. The junction of section 61s2 and section 61s3 includes a junction 61t 2. The junction of section 61s1 and section 61s2 includes a junction 61t 3.

Each of the contact 61t1, the contact 61t2, and the contact 61t3 may also be referred to as a bent section.

In some embodiments, the junction 61t1, the junction 61t2, and the junction 61t3 may have different radii of curvature. In general, the larger the radius of curvature, the smaller the curvature, and vice versa. In certain embodiments, the radius of curvature of the junction 61t1 is less than the radius of curvature of the junction 61t 2. In certain embodiments, the radius of curvature of the junction 61t2 is less than the radius of curvature of the junction 61t 3. In some embodiments, the radius of curvature of the junction 61t1 may be about 0.8 mm. In some embodiments, the radius of curvature of the junction 61t2 may be about 0.7 mm. In some embodiments, the radius of curvature of the junction 61t3 may be about 2 mm.

Segment 61s1, segment 61s2, segment 61s3, and segment 61s4 may each have a different direction of extension. The extending direction of the segment 61s1 is different from the extending direction of the segments 61s2, 61s3 and 61s 4. The extending direction of the segment 61s2 is different from the extending direction of the segments 61s3 and 61s 4. The extending direction of the section 61s3 is different from the extending direction of the section 61s 4.

Segment of61s1 extend in the y-axis direction as shown in FIG. 10A. The angle θ formed between the segment 61s2 and the segment 61s1 (i.e., the y-axis direction)₁. The section 61s3 forms an included angle theta with the y-axis direction₂。

In some embodiments, the included angle θ₁In the range of 60 ° to 75 °. In some embodiments, the included angle θ₁In the range of 65 ° to 70 °. In some embodiments, the included angle θ₂In the range of 10 ° to 30 °. In some embodiments, the included angle θ₂In the range of 15 ° to 25 °.

During assembly of the cartridge 100A, the metal structure 6a will move upwardly along the y-axis direction shown in figure 10A into contact with the aerosol-generating assembly 3. After the aerosol-generating assembly 3 contacts the metal structure 6a, a downward force Fy along the y-axis direction is applied to the resilient piece structure 61 from the contact 61t 1. The spring structure 61 is deformed by the force Fy. Different sections of the spring structure 61 will be displaced in different directions upon application of the force Fy.

Referring to FIG. 10A, segment 61s2 moves in the rightward direction along the x-axis when subjected to force Fy, and segment 61s3 moves in the leftward direction along the x-axis when subjected to force Fy.

In detail, when the spring structure 61 is subjected to the force Fy, the section 61s2 moves downward along the y-axis direction, and the contact 61t2 moves rightward along the x-axis direction. In addition, segment 61s3 moves downward along the y-axis and causes contact 61t1 to move leftward along the x-axis.

In some embodiments, the action of the force Fy results in a displacement length of the contact 61t1 that is about the same as the displacement length of the contact 61t 2. Therefore, when the leaf spring structure 61 is subjected to the force Fy, the leftward displacement of the contact 61t1 may approximately cancel the rightward displacement of the contact 61t 2.

In some embodiments, the difference between the displacement length of the contact 61t1 and the displacement length of the contact 61t2 may be in the range of 0.05mm to 0.15mm when the dome structure 61 is subjected to the force Fy. In some embodiments, the difference between the displacement length of the contact 61t1 and the displacement length of the contact 61t2 may be in the range of 0.2mm to 0.65mm when the dome structure 61 is subjected to the force Fy.

Figure 10B shows a perspective view of the aerosol-generating assembly 3 and the metal structure 6 a. When the shrapnel structure 61 and the aerosol-generating component 3 are assembled into the cartridge 100A, the contact point 61t1 and the contact point 31p1 of the heat generating member 31 are in contact with each other.
