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 only examples and are not intended to be limiting. In this application, the reference to the formation of the first feature on or on the second feature in the following description may include an embodiment in which the first feature is directly contacted with the second feature, and may also include additional features that may be formed on An embodiment between the first feature and the second feature so that the first feature and the second feature may not be in direct contact. In addition, this application may repeat reference numerals and/or letters in various examples. This repetition is for the purpose of simplification and clarity, and does not in itself indicate the relationship between the various embodiments and/or configurations discussed.

The embodiments of the present application are discussed in detail below. However, it should be understood that this application provides many applicable concepts that can be implemented in a variety of specific situations. The specific embodiments discussed are merely illustrative and do not limit the scope of the application. In this context, the term "aerosol for user inhalation" may include, but is not limited to, aerosols, suspended liquids, low-temperature vapors, and volatile gases.

The existing electronic cigarette products do not consider the pressure balance of the oil storage chamber. In existing electronic cigarette products, the oil storage chamber is generally designed to be completely sealed to prevent the vaporizable solution from overflowing. The manufactured electronic cigarette products may increase the pressure in the oil storage chamber due to changes in temperature or air pressure during the transportation process. The increase in the pressure in the oil storage chamber will cause a large amount of e-liquid to flow to the aerosol generating component, and can cause the problem of e-liquid leakage of electronic cigarette products. In addition, as users continue to use electronic cigarette products, the vaporizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber decreases and a negative pressure is formed. The negative pressure makes it difficult for the vaporizable solution in the oil storage chamber to evenly flow to the aerosol generating component, so that the aerosol generating component does not uniformly adsorb the vaporizable solution. At this time, when the temperature of the aerosol generating component rises, there will be a high probability of empty burning and a burnt smell, resulting in a bad user experience.

The air inlet hole 4f includes a first through hole 401 located near the center and a plurality of second through holes 402 surrounding the central opening. In some embodiments, the number of the second through holes 402 may be five. In some embodiments, the number of second through holes 402 may be greater than five. In some embodiments, the number of second through holes 402 may be less than five.

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 0.55 mm to 0.75 mm. In some embodiments, the aperture size of the first through hole 401 is approximately 0.65 mm. In some embodiments, the aperture size of the second through hole 402 may be in the range of 0.40 mm to 0.50 mm. In some embodiments, the aperture size of the second through hole 402 is about 0.46 mm.

In some embodiments, after the cartridge 100A is assembled, the first through hole 401 of the air inlet 4f may be aligned with the geometric center of the bottom surface of the aerosol generating assembly 3. According to the results of the software simulation experiment, the first through hole 401 with a larger diameter can make the fresh air blow more uniformly on the heating element 31 at the bottom of the aerosol generating assembly 3, thereby improving the aerosol generating efficiency of the aerosol generating assembly 3.

In the direction perpendicular to the bottom surface of the aerosol generating assembly 3, the first through hole 401 is located below the aerosol generating assembly 3 and roughly corresponds to the center of the aerosol generating assembly 3, and the second through holes 402 are all located at the aerosol generating assembly. 3 within the projection range.

Refer to Figure 6C and Figure 6D at the same time. The contact structure 62 completely covers the opening 4h1, and the contact structure 64 completely covers the opening 4h2. The contact structure 62 can prevent the e-liquid or condensed liquid in the cartridge 100A from leaking from the opening 4h1 to the outside of the cartridge 100A. The contact structure 64 can prevent the e-liquid or condensed liquid in the cartridge 100A from leaking from the opening 4h2 to the outside of the cartridge 100A.

After the cartridge 100A is assembled, the distance between the upper surface 4s of the air inlet 4f and the bottom of the aerosol generating assembly 3 may be in the range of 1.5mm to 3.5mm. In some embodiments, the distance between the upper surface 4s of the air inlet 4f and the bottom of the aerosol generating assembly 3 may be in the range of 2mm to 3mm. The software simulation results show that the above-mentioned distance setting can improve the aerosol generation efficiency of the aerosol generating assembly 3. The above-mentioned distance setting can increase the amount of aerosol generated by the aerosol generating assembly 3.

Fig. 6E illustrates a schematic top view of the lower cover according to some embodiments of the present application. The air intake hole 4f is provided between the columnar structure 4p1 and the columnar structure 4p2. The air inlet 4f includes a first through hole 401 and a plurality of second through holes 402 surrounding the first through hole 401. The shrapnel structure 61 and the shrapnel structure 63 are respectively arranged on both sides of the air inlet 4f. The shrapnel structure 61 is arranged between the air inlet 4f and the columnar structure 4p1. The shrapnel structure 63 is disposed between the air inlet 4f and the columnar structure 4p2.

Figure 7A shows three components in the cartridge 100A. Fig. 7A shows a cross-sectional view of the cartridge case 1, the upper cover 2, and the lower cover 4.

The cartridge case 1 includes a tube 1t extending toward the upper cover 2. The tube 1t may include a first part 1t1 and a second part 1t2. The first part 1t1 and the second part 1t2 may have different outer diameters. In some embodiments, the outer diameter of the first portion 1t1 is greater than the outer diameter of the second portion 1t2. The smaller outer diameter of the second part 1t2 makes it easier for the tube 1t to be inserted into the tubular structure 2m1 of the upper cover 2.

The tube 1t may have an uneven inner diameter. In some embodiments, the inner diameter of the tube 1t may have a difference of 1s between the first part 1t1 and the second part 1t2. The step difference of 1s can also be called a stepped 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 1t1. The inner diameter 1w1 is different from the inner diameter 1w2. In some embodiments, the inner diameter 1w2 is smaller than the inner diameter 1w1.

When the aerosol generated by the aerosol generating assembly 3 passes along the tube 1t toward the opening 1h1, it will pass a step difference of 1s. After the aerosol has a step difference of 1s, the inner diameter of the tube 1t is enlarged (from 1w2 to 1w1), which can reduce the probability of condensation of the aerosol on the inner wall of the tube 1t to produce condensed liquid. The step difference of 1s can reduce the amount of condensed liquid generated during the use of the cartridge 100A, thereby reducing the probability of leakage of condensed liquid during use.

In some embodiments, the inner diameter of the tube 1 t has a smaller inner diameter at a part close to the upper cover 2 and a larger inner diameter at a part far away from the upper cover 2. In some embodiments, the inner diameter of the tube 1t has a smaller inner diameter at a portion close to the aerosol generating assembly 3, and a larger inner diameter at a portion far away from the aerosol generating assembly 3. As shown in FIG.

The inner wall of the cartridge case 1 further includes a stepped structure 1d. The stepped structure 1d may be formed by the uneven thickness of the cartridge case 1. The stepped structure 1d can be formed by the inner surface 1ds1 and the inner surface 1ds2 of the cartridge case 1. The inner surface 1ds1 of the cartridge case 1 may not be coplanar with the inner surface 1ds2 of the cartridge case 1. There may be a difference between the inner surface 1ds1 of the cartridge case 1 and the inner surface 1ds2 of the cartridge case 1. During the assembly process of the cartridge 100A, the stepped structure 1d can provide resistance between the cartridge housing 1 and the upper cover 2. The top sealing structure 2t of the upper cover 2 abuts the stepped structure 1d and reaches a predetermined position. At this time, the lower cover 4 is continuously applied with a force toward the upper cover 2, which can cause the thin protrusion 4d1 and the thin protrusion of the columnar structure 4p1 4d3 is deformed, and the columnar structure 4p1 is deepened and fixed in the upper cover 2. Similarly, the two thin protrusions of the columnar structure 4p2 are also deformed, so that the columnar structure 4p2 is deep and fixed in the upper cover 2.

Figure 7B illustrates 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, after the cartridge 100A is assembled, the overhanging structure 2t1 of the top sealing structure 2t can abut between the tube 1t and the tubular structure 2m1 to provide a sealing effect between the tube 1t and the tubular structure 2m1. The overhanging structure 2t1 can be arranged on the upper surface of the tubular structure 2m1. The overhanging structure 2t1 can be arranged between the upper surface of the tubular structure 2m1 and the stepped structure 1d2 of the tube 1t (see FIG. 7A).

After the cartridge 100A is assembled, a part of the tube 1t (ie, the part 1t2) can extend into the tubular structure 2m1. In this case, the protrusion 2t2 of the top sealing structure 2t can provide a sealing effect between the tube 1t and the tubular structure 2m1.

The storage compartment 10 is defined between the top sealing structure 2t, the tube 1t, and the inner surface 1s2 of the cartridge shell 1. The storage compartment 10 can contain e-liquid. After the cartridge 100A is assembled, the protrusion 2t3 of the top sealing structure 2t can abut the inner surface 1s1 of the cartridge case 1 to provide a sealing effect between the upper cover 2 and the cartridge case 1. After the cartridge 100A is assembled, the aerosol generating assembly sealing portion 2t4 of the top sealing structure 2t can abut against the top of the aerosol generating assembly 3 to provide a sealing effect between the upper cover 2 and the aerosol generating assembly 3. The aerosol generating assembly sealing portion 2t4 may surround the groove 3c of the aerosol generating assembly 3.

After the cartridge 100A is assembled, the protrusion 2b1 of the bottom sealing structure 2b can abut the inner surface 1s1 of the cartridge case 1 to provide a sealing effect between the upper cover 2 and the cartridge case 1.

After the upper cover 2 and the lower cover 4 are assembled, the overhanging structure 2b2 of the bottom sealing structure 2b can abut against the surfaces 4s1 of the upper cover 2 and the lower cover 4, thereby providing a seal between the upper cover 2 and the lower cover 4 Effect.

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

Fig. 8 illustrates a schematic diagram of the assembly of the cartridge according to some embodiments of the present application. FIG. 8 illustrates the relative positions of the upper cover 2 and the lower cover 4 after the first stage of assembly of the cartridge 100A is completed. For simplicity of description, drawing of the suction assembly 5a and the suction assembly 5b is omitted in FIG. 8. The above components should be included in the actual assembly process of the cartridge 100A.

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

The upper cover 2 has a window 201 and a window 202 on both sides. In the first stage of assembly of the lower cover 4 and the upper cover 2, a force is applied to the bottom of the lower cover 4 toward the upper cover 2 so that the columnar structure 4p1 penetrates into the upper cover 2. The force applied to the lower cover 4 can make the snap protrusion 4d2 and snap protrusion 4d4 of the columnar structure 4p1 reach into the window 201 and the window 202, respectively.

The buckle protrusion 4d2 may include inclined surfaces 421 and 422 to facilitate the columnar structure 4p1 to pass through the bottom edge 2e1 and penetrate into the upper cover 2. The buckle protrusion 4d4 may include

inclined surfaces

441 and 442 so that the columnar structure 4p1 can pass through the bottom edge 2e2 and penetrate into the upper cover 2.

When the locking protrusion 4d2 reaches the window 201, the thin protrusion 4d1 of the columnar structure 4p1 abuts against the bottom edge 2e1 of the upper cover 2, and the locking protrusion 4d2 of the columnar structure 4p1 abuts against the surface 201s of the window 201. Similarly, when the snap protrusion 4d4 reaches the window 202, the thin protrusion 4d3 of the columnar structure 4p1 abuts against the bottom edge 2e2 of the upper cover 2, and the snap protrusion 4d4 of the columnar structure 4p1 abuts against the surface of the window 202 202s. After the above-mentioned first stage of assembly, the lower cover 4 and the upper cover 2 become a single component 24 connected to each other, which is convenient for transporting all the components of the cartridge 100A to the destination before proceeding to the second stage of assembly.

As shown in FIG. 8, after the first stage of assembly, the columnar structure 4p1 has not yet fully penetrated into the valve structure 2v1, so that a gap between the columnar structure 4p1 and the valve structure 2v1 for fluid passage is still maintained.

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

Figure 9A illustrates a schematic diagram of the assembly of the cartridge according to some embodiments of the present application. FIG. 9A illustrates a schematic diagram of the second stage assembly of the cartridge 100A.

FIG. 9A shows the lower cover 4, the upper cover 2 and the cartridge case 1. It should be noted that, for the sake of simplicity of description, the aerosol generating assembly 3 and the drawing of the adsorption assembly 5a and the adsorption assembly 5b are omitted in FIG. 9A. The above components should be included in the actual assembly process of the cartridge 100A.

As mentioned in the above related paragraphs about Fig. 8, the lower cover 4 and the upper cover 2 will be 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. Proceed to the second stage of assembly.

As shown in Figure 9A, during the second stage of assembly, the cartridge housing 1 has been filled with 100l of e-liquid, and then a part of the single component 24 is pushed into the cartridge housing 1, so that the single component 24 and the cartridge The housings 1 are fixed to each other. When the single component 24 and the cartridge case 1 are not fixed to each other, there is a gap/channel between the valve structure 2v1 of the upper cover 2 and the columnar structure 4p1 of the lower cover 4. During the assembly process of the single component 24 and the cartridge case 1, the passage between the valve structure 2v1 and the columnar structure 4p1 can allow the gas in the cartridge case 1 to be discharged along the path 2f1, which can prevent the cartridge 100A from being assembled. over stressed. Similarly, the passage between the valve structure 2v2 and the columnar structure 4p2 can allow the gas in the cartridge housing 1 to be discharged along the path 2f2, which can avoid excessive internal pressure after the cartridge 100A is assembled. Excessive pressure inside the cartridge 100A may cause e-liquid leakage, reduce the volume rate of the product, and may also cause a bad user experience.

8 and 9A at the same time, in the second stage assembly of the cartridge 100A, the thin protrusion 4d1 and the thin protrusion 4d3 of the columnar structure 4p1 also play an important role. In the second stage of the assembly process, the lower cover 4 can be continuously applied with a force toward the cartridge housing 1 until the top sealing structure 2t of the upper cover 2 abuts against the stepped structure 1d in the cartridge housing 1 (see Figure 7A ).

While the lower cover 4 is continuously applied, the thin protrusion 4d1 can transmit the applied force to the upper cover 2 via the bottom edge 2e1 of the upper cover 2 to ensure that the upper cover 2 can reach the predetermined position in the cartridge housing 1. Similarly, the thin protrusion 4d3 can transmit force to the upper cover 2 via the bottom edge 2e2 of the upper cover 2 during the second stage of assembly process, so as to ensure that the upper cover 2 can reach the predetermined position in the cartridge housing 1.

Figure 9B illustrates a cross-sectional view of a cartridge according to some embodiments of the present application. FIG. 9B illustrates a cross-sectional view of the cigarette cartridge 100A after being assembled. It should be noted that, for simplicity of description, the drawing of the metal structure 6a, the metal structure 6b, the suction component 5a, and the suction component 5b are omitted in FIG. 9B. After the cartridge 100A is assembled, the above components should be included.

As shown in FIG. 9B, when the lower cover 4 and the upper cover 2 are fixed at the predetermined positions in the cartridge case 1, the valve structure 2v1 and the columnar structure 4p1 are closely attached, and the valve structure 2v2 and the columnar structure 4p2 are closely attached to each other. combine. The valve structure 2v1 surrounds a part of the columnar structure 4p1 and exposes the top surface 4p1s of the columnar structure 4p1. The valve structure 2v2 surrounds a part of the columnar structure 4p2 and exposes the top surface 4p2s of the columnar structure 4p2.

After the cartridge 100A is assembled, the valve structure 2v1 becomes a one-way air exchange valve. After the cartridge 100A is assembled, the valve structure 2v1 can have the functions of a one-way valve and a ventilation valve.

After the cartridge 100A is assembled, the pressure in the storage compartment 10 can be slightly greater than the pressure in the atomization chamber 40. At this time, the pressure in the storage compartment 10 can make the elastic structure 2p1 fit the columnar structure 4p1, or make the elastic structure 2p1 face Move in the direction approaching the columnar structure 4p1. Similarly, the pressure in the storage compartment 10 can cause the elastic structure 2p2 to fit the columnar structure 4p2, or cause the elastic structure 2p2 to move toward the columnar structure 4p2.

As a one-way valve, the valve structure 2v1 can prevent the e-liquid in the storage compartment 10 from leaking out of the storage compartment 10 from between the valve structure 2v1 and the columnar structure 4p1. As a one-way valve, the valve structure 2v2 can prevent the e-liquid in the storage compartment 10 from leaking out of the storage compartment 10 from between the valve structure 2v2 and the columnar structure 4p2.

After the user continues to use the cartridge 100A, the volume of the e-liquid in the storage compartment 10 is continuously reduced, and the pressure in the storage compartment 10 is continuously reduced. The pressure drop in the storage compartment 10 may make it difficult for the e-liquid to flow to the aerosol generating assembly 3. The pressure reduction in the storage compartment 10 may make the autoclave assembly 3 unable to fully absorb the smoke oil, which may cause a burnt or bitter taste during the heating process.

When the pressure difference between the pressure in the storage compartment 10 and the pressure in the atomization chamber 40 reaches the threshold, the air in the atomization chamber 40 can push the elastic structure 2p1 of the valve structure 2v1 through the path 4f1 and enter the storage compartment 10, thereby The pressure of the storage compartment 10 and the atomization chamber 40 is balanced. When the difference between the pressure in the storage compartment 10 and the pressure in the atomization chamber 40 reaches the threshold, the air in the atomization chamber 40 can push away the elastic structure 2p1, causing the elastic structure 2p1 to move away from the columnar structure 4p1 . The air in the atomization chamber 40 can deform the elastic structure 2p1 without contacting the columnar structure 4p1.

Similarly, when the pressure difference between the pressure in the storage compartment 10 and the pressure in the atomization chamber 40 reaches the threshold, the air in the atomization chamber 40 can push open the elastic structure 2p2 of the valve structure 2v2 through the path 4f2 and enter the storage compartment 10. In order to balance the pressure of the storage compartment 10 and the atomization chamber 40. The air in the atomization chamber 40 can push the elastic structure 2p2 away, so that the elastic structure 2p2 moves in a direction away from the columnar structure 4p2. The air in the atomization chamber 40 can deform the elastic structure 2p2 without contacting the columnar structure 4p2.

As a ventilation valve, the valve structure 2v1 can reduce the probability of dry burning when the cartridge 100A is heated, and is beneficial for the user to fully use the e-liquid in the storage compartment 10 completely. As a ventilation valve, the valve structure 2v2 can reduce the probability of dry burning when the cartridge 100A is heated, and is beneficial for the user to fully use the e-liquid in the storage compartment 10.

Figure 9C illustrates a cross-sectional view of a cartridge according to some embodiments of the present application. FIG. 9C illustrates a cross-sectional view of the cartridge 100A including the upper cover 2'after being assembled. It should be noted that, for simplicity of description, the drawing of the metal structure 6a, the metal structure 6b, the suction component 5a, and the suction component 5b are omitted in FIG. 9C. After the cartridge 100A is assembled, the above components should be included.

After the lower cover 4 and the upper cover 2'are fixed at the predetermined positions in the cartridge housing 1, the valve structure 2v1' and the columnar structure 4p2 are closely attached. After 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 the e-liquid in the storage compartment 10 is continuously reduced, and the pressure in the storage compartment 10 is continuously reduced. When the pressure difference between the pressure in the storage compartment 10 and the pressure in the atomization chamber 40 reaches the threshold, the air in the atomization chamber 40 can push open the elastic structure 2p1' of the valve structure 2v1' through the path 4f1' and enter the storage compartment 10 In order to balance the pressure of the storage compartment 10 and the atomization chamber 40. As a ventilation valve, the valve structure 2v1' can reduce the probability of dry burning when the cartridge 100A is heated, and is beneficial for the user to fully use the e-liquid in the storage compartment 10 completely. As a one-way valve, the valve structure 2v1' can prevent the e-liquid in the storage compartment 10 from leaking out of the storage compartment 10 from between the valve structure 2v1' and the columnar structure 4p2.

As shown in FIG. 9C, the upper cover 2'only contains the valve structure 2v1' on one side, and the other side contains a cavity 2c. The cavity 2c can accommodate the columnar structure 4p1 of the lower cover 4. Only including a single valve structure 2v1' can reduce the manufacturing cost of the upper cover 2'. Containing only a single valve structure 2v1' can reduce the manufacturing difficulty of the upper cover 2'. Containing only a single valve structure 2v1' can improve the yield of the upper cover 2'.

Figure 9D illustrates a cross-sectional view of the upper cover and the lower cover according to some embodiments of the present application. FIG. 9D shows the relative positions of the upper cover 2 and the lower cover 4 after the second stage of assembly of the cartridge 100A is completed. For simplicity of description, the drawing of the cartridge case 1 is omitted in FIG. 9D.

When the lower cover 4 reaches the default position in the upper cover 2, the thin protrusion 4d1 and the thin protrusion 4d3 will be deformed due to compression. As shown in FIG. 9D, when the thin protrusion 4d1 reaches the default position in the upper cover 2, it deforms into a protrusion 4d1 ′, and abuts against the inner surface 2s1 of the upper cover 2. The thin protrusion 4d3 deforms into a protrusion 4d3' when reaching the default position in the upper cover 2, and abuts against the inner surface 2s2 of the upper cover 2.

The extending direction of the inclined surface 421 and the columnar structure 4p1 may include an included angle θ ₄₂₁ , and the extending direction of the inclined surface 422 and the columnar structure 4p1 may include an included angle θ ₄₂₂ . In some embodiments, the included angle θ ₄₂₁ may be the same as the _{included angle θ 422.} In some embodiments, the included angle θ ₄₂₁ may be different from the included angle θ _422. In some embodiments, the included angle θ ₄₂₁ may be in the range of 10° to 25°. In some embodiments, the included angle θ ₄₂₂ may be in the range of 15° to 20°.

The extending direction of the inclined surface 441 and the columnar structure 4p1 may include an included angle θ ₄₄₁ , and the extending direction of the inclined surface 442 and the columnar structure 4p1 may include an included angle θ ₄₄₂ . In some embodiments, the included angle θ ₄₄₁ may be the same as the _{included angle θ 442.} In some embodiments, the included angle θ ₄₄₁ may be different from the included angle θ _442. In some embodiments, the included angle θ ₄₄₁ may be in the range of 10° to 25°. In some embodiments, the included angle θ ₄₄₂ may be in the range of 15° to 20°.

After the cartridge 100A is assembled in the second stage, the columnar structure 4p1 and the valve structure 2v1 are in contact with each other. After the cartridge 100A is assembled in the second stage, the valve structure 2v1 surrounds and contacts the circumference of the columnar structure 4p1. After the cartridge 100A is assembled in the second stage, the valve structure 2v1 has the function of one-way ventilation.

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

The metal structure 6a and the lower cover 4 are formed by integral injection molding (see FIG. 6A), so the metal structure 6a is embedded in the lower cover 4. During the assembly process of the cartridge 100A, the metal structure 6a will contact the bottom of the aerosol generating assembly 3 as the lower cover 4 is placed in the cartridge housing 1. In order to more clearly introduce the relative relationship between the aerosol generating assembly 3 and the metal structure 6a, the lower cover 4 is omitted in FIG. 10A.

The shrapnel structure 61 of the metal structure 6a may include several parts. The shrapnel structure 61 may include several parts connected to each other. The shrapnel structure 61 may include several sections connected to each other. As shown in FIG. 10A, the shrapnel structure 61 may include a section 61s1, a section 61s2, a section 61s3, and a section 61s4.

The section 61s1 and the section 61s2 are connected to each other. The section 61s2 and the section 61s3 are connected to each other. The section 61s3 and the section 61s4 are connected to each other. The connection between the section 61s3 and the section 61s4 includes a contact point 61t1. The connection between the section 61s2 and the section 61s3 includes a contact point 61t2. The connection between the section 61s1 and the section 61s2 includes a contact point 61t3.

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

In some embodiments, the contact 61t1, the contact 61t2, and the contact 61t3 may have different radii of curvature. Generally speaking, the larger the radius of curvature, the smaller the curvature, and vice versa. In some embodiments, the radius of curvature of the contact 61t1 is smaller than the radius of curvature of the contact 61t2. In some embodiments, the radius of curvature of the contact 61t2 is smaller than the radius of curvature of the contact 61t3. In some embodiments, the radius of curvature of the contact 61t1 may be about 0.8 mm. In some embodiments, the radius of curvature of the contact 61t2 may be about 0.7 mm. In some embodiments, the radius of curvature of the contact 61t3 may be about 2 mm.

The section 61s1, the section 61s2, the section 61s3, and the section 61s4 may each have a different extending direction. The extending direction of the section 61s1 is different from the extending directions of the section 61s2, the section 61s3, and the section 61s4. The extending direction of the section 61s2 is different from the extending directions of the section 61s3 and the section 61s4. The extending direction of the section 61s3 is different from the extending direction of the section 61s4.

The section 61s1 extends in the y-axis direction as shown in FIG. 10A. The section 61s2 and the section 61s1 (that is, the y-axis direction) form an included angle θ ₁ . The section 61s3 forms an angle θ ₂ with the y-axis direction.

In some embodiments, the included angle θ _{1 is} in the range of 60° to 75°. In some embodiments, the included angle θ _{1 is} in the range of 65° to 70°. In some embodiments, the included angle θ _{2 is} in the range of 10° to 30°. In some embodiments, the included angle θ _{2 is} in the range of 15° to 25°.

During the assembly process of the cartridge 100A, the metal structure 6a will move upward along the y-axis direction shown in FIG. 10A to contact the aerosol generating assembly 3 with each other. After the aerosol generating assembly 3 is in contact with the metal structure 6a, a downward force Fy along the y-axis direction will be applied to the elastic sheet structure 61 from the contact 61t1. The shrapnel structure 61 will deform after receiving the force Fy. Different sections of the shrapnel structure 61 will produce displacements in different directions after being acted on by the force Fy.

Referring to FIG. 10A, when the section 61s2 receives the force Fy, it moves in the right direction along the x-axis, and when the section 61s3 receives the force Fy, it moves in the left direction along the x-axis.

In detail, after the shrapnel structure 61 receives the force Fy, the section 61s2 will move downward along the y-axis direction, and cause the contact point 61t2 to move rightward along the x-axis direction.
