[0050] Please refer to Figures 1 - 12, the aerosol generator provided by the embodiments of the present application will now be described.

[0051] This embodiment provides an aerosol generator, including a cup body 11 and a squeezing assembly 300.

[0052] A first accommodation cavity 111 and a second accommodation cavity 112 are formed inside the cup body 11. One end of the second accommodation cavity 112 opens to the outer surface of the cup body 11, and a silica gel member 400 is provided at the other end where the second accommodation cavity 112 communicates with the first accommodation cavity 111.

[0053] Please refer to Figure 1 , which shows an aerosol generator of a structure. Figure 1 The cup body 11 is shown in Figure 2 For Figure 1 the explosion schematic diagram of the aerosol generator shown in Figure 5 . Please refer to Figure 5 , Figure 5 which is the sectional schematic diagram of the cup body 11. From

[0054] , it can be seen that a first accommodation cavity 111 and a second accommodation cavity 112 are formed inside the cup body 11. The first accommodation cavity 111 is used to accommodate the aerosol matrix, and the second accommodation cavity 112 is used to accommodate the squeezing assembly 300. By operating the squeezing assembly 300, the solvent of the bursting bead 33 is added to the first accommodation cavity 111, so that the solvent of the bursting bead 33 can be incorporated into the aerosol matrix inside the aerosol generator.

[0055] Please refer to Figure 5 , which shows that a silica gel member 400 is provided at the communicating end between the second accommodation cavity 112 and the first accommodation cavity 111.

[0056] In this embodiment, an exhaust passage is formed between the squeezing assembly 300 and the second accommodation cavity 112. The positional relationship between the squeezing assembly 300 and the silica gel member 400 includes a first positional relationship and a second positional relationship. When the squeezing assembly 300 and the silica gel member 400 are in the first positional relationship, there is a gap therebetween for forming a temporary exhaust passage. When the squeezing assembly 300 and the silica gel member 400 are in the second positional relationship, they are in sealing cooperation.

[0057] By providing an exhaust passage and a temporary exhaust passage, during the process of adding the bead solvent into the first accommodation cavity 111 through the pressing assembly 300, gas can be discharged from the first accommodation cavity 111 through the temporary exhaust passage and the exhaust passage, preventing the air pressure inside the first accommodation cavity 111 from increasing and reducing the risk of extruding the aerosol matrix inside the aerosol generator.

[0058] Regarding the cooperation between the pressing assembly 300 and the silica gel part 400, different cooperation situations exist during the process of the pressing assembly 300 adding the bead solvent into the first accommodation cavity 111. There is a gap between the pressing assembly 300 and the silica gel part 400 at a certain time or during a certain period, and the gap between the two forms a temporary exhaust passage, that is, the pressing assembly 300 and the silica gel part 400 are in a first positional relationship. When the bead 33 solvent is added into the first accommodation cavity 111 through the pressing assembly 300 and gas is squeezed into the first accommodation cavity 111, the excess gas in the first accommodation cavity 111 can be discharged into the second accommodation cavity 112 through the temporary exhaust passage and then discharged from the first accommodation cavity 111 through the exhaust passage between the pressing assembly 300 and the second accommodation cavity 112; after the bead 33 solvent has been added into the first accommodation cavity 111 and the excess gas in the first accommodation cavity 111 has been discharged, with the movement of the pressing assembly 300, a seal is formed between the pressing assembly 300 and the silica gel part 400 after the pressing assembly 300 finishes flavoring, that is, the pressing assembly 300 and the silica gel part 400 are in a second positional relationship, and there is no gap between the pressing assembly 300 and the silica gel part 400, and the temporary exhaust passage disappears.

[0059] The aerosol generator provided in this embodiment can be applied to aerosol generating devices of replaceable aerosol generators or non - replaceable aerosol generators.

[0060] In one embodiment, referring to Figure 2 , the aerosol generator includes an oil - blocking part 13 and a mouthpiece part 14. The oil - blocking part 13 is arranged between the cup body 11 and the mouthpiece part 14, and the oil - blocking part 13 plays a sealing role to prevent oil leakage from the cup body 11. Based on this embodiment, for the description above that one end of the second accommodation cavity 112 opens to the outer surface of 11, preferably, one end of the second accommodation cavity 112 opens to the end face of the cup body 11 on the side where the oil - blocking part 13 is installed.

[0061] Please refer to Figure 4 , which shows a cross - sectional schematic view of the aerosol generator when the pressing assembly 300 is not placed in the second accommodation cavity 112; please refer to Figure 3 , which shows a cross - sectional schematic view of the aerosol generator when the pressing assembly 300 is placed in the second accommodation cavity 112. From Figure 3 and Figure 4It can be seen from the comparison that after the extrusion assembly 300 is installed in place in the second accommodating cavity 112, the addition of the extrusion assembly 300 does not affect the installation of the oil blocking member 13 and the mouth member 14 on the cup body 11, that is, the extrusion assembly 300 can be limited between the oil blocking member 13 and the silicone member 400. After the extrusion assembly 300 is installed in the second accommodating cavity 112, it does not need to be disassembled.

[0062] In one embodiment, see Figure 2 The aerosol generator further comprises a seat 12, an aerosol generating assembly 200, a mounting member 15, etc., wherein the cup 11, the seat 12, the oil blocking member 13, the mouthpiece 14 and the mounting member 15 form the generator supporting body 100. Figure 2 The seat body 12 is installed on the side of the cup body 11 away from the mouthpiece 14 , the aerosol generating assembly 200 is installed on the seat body 12 , and the mounting member 15 is connected to the side of the aerosol generating assembly 200 away from the seat body 12 .

[0063] In one embodiment, see Figure 5 The cup body 11 includes a shell main body 113 and an arc-shaped plate portion 114. Both ends of the arc-shaped plate portion 114 are connected to the inner side surface of the shell main body 113. A second accommodating cavity 112 is formed between the arc-shaped plate portion 114 and the shell main body 113. One end of the arc-shaped plate portion 114 along the axial direction extends to the end surface of the shell main body 113 and is flush with the end surface of the shell main body 113. The other end of the arc-shaped plate portion 114 along the axial direction is clamped with a silicone component 400. Figure 5 is a cross-sectional schematic diagram of the cup body 11, Figure 5 The shell body portion 113 and the arc-shaped plate portion 114 are schematically shown, and the positional relationship between the second accommodating cavity 112 and the first accommodating cavity 111 is schematically shown.

[0064] Preferably, the cup body 11 is an integrally formed part, and the axis of the second accommodating cavity 112 is parallel to the axis of the first accommodating cavity 111 .

[0065] For the connection structure between the arc-shaped plate portion 114 and the silicone member 400, see Figure 5 An annular plate is connected to the shell body portion 113 and the arc-shaped plate portion 114 , and the silicone member 400 is clamped on the annular plate.

[0066] Regarding the specific structure of the extrusion assembly 300, in one embodiment, see Figure 2 and Figure 6, the extrusion assembly 300 includes an extrusion housing 31, an extrusion rod 32, and a bursting bead 33. An inner cavity communicating with both ends is formed inside the extrusion housing 31. The bursting bead 33 is located inside the inner cavity. The extrusion rod 32 is inserted into the inner cavity through one end of the extrusion housing 31. The extrusion rod 32 is in sealing fit with the extrusion housing 31. The extrusion rod 32 can move in the direction of inserting into the extrusion housing 31 under an external force to extrude the bursting bead 33.

[0067] Please refer to Figure 6 , which shows the extrusion rod 32 inserted into the inner cavity through one end of the extrusion housing 31. The other end of the extrusion housing 31 is used to insert into the silica gel part 400. In order to prevent the aerosol matrix in the first accommodation cavity 111 from overflowing through the inner cavity in the extrusion housing 31, preferably, the extrusion rod 32 is in sealing fit with the extrusion housing 31.

[0068] Refer to Figure 6 , which can be regarded as the initial state of the extrusion assembly 300. In this state, when the extrusion rod 32 is pushed downward, the extrusion rod 32 moves downward and can extrude the bursting bead 33. After the bursting bead 33 bursts, the solvent inside it can flow out through one end of the extrusion housing 31.

[0069] Preferably, the extrusion assembly 300 is detachably connected. When assembling the extrusion assembly 300, first put the bursting bead 33 into one end of the extrusion housing 31, and then install the extrusion rod 32 and insert the extrusion rod 32 into the extrusion housing 31 from one end.

[0070] Exemplarily, the connection structure between the extrusion rod 32 and the extrusion housing 31 can be as follows: a clamping groove 318 is provided on the circumferential side of one of the extrusion housing 31 and the extrusion rod 32, and a clamping protrusion 324 is provided on the other. The clamping protrusion 324 is located in the clamping groove 318 to position the extrusion rod 32 on the extrusion housing 31. Refer to Figure 6 and Figure 7 , which shows the clamping protrusion 324 provided on the extrusion rod 32 and the clamping groove 318 provided on the inner side surface of the extrusion housing 31.

[0071] The clamping structure formed by the cooperation of the clamping protrusion and the groove has not very high connection strength. It mainly serves to position the extrusion rod 32 on the extrusion housing 31. When a certain magnitude of external force is applied to the extrusion rod 32, the clamping connection formed by the extrusion housing 31 and the extrusion rod 32 through the clamping protrusion 324 and the clamping groove 318 can be released.

[0072] Exemplarily, the extrusion rod 32 and the extrusion housing 31 may not be provided with a connection structure, that is, no clamping protrusion and groove matching structure is provided between the extrusion housing 31 and the extrusion rod 32. When assembling the extrusion assembly 300, directly insert the extrusion rod 32 into the extrusion housing 31.

[0073] An exhaust passage is formed between the extrusion assembly 300 and the second accommodation cavity 112. In one embodiment, side air grooves 311 are provided on the circumferential outer surface of the extrusion housing 31, and both ends of the side air grooves 311 extend to both ends of the extrusion housing 31 to form the exhaust passage. Please refer to Figure 6 , Figure 8 and Figure 10 , which shows that side air grooves 311 are provided on the circumferential outer surface of the extrusion housing 31, and the gas in the second accommodation cavity 112 can be discharged outside the cup body 11 through the side air grooves 311.

[0074] An exhaust passage is formed between the extrusion assembly 300 and the second accommodation cavity 112. In another embodiment, side air grooves for forming the exhaust passage are formed on the inner surface of the second accommodation cavity 112. That is, side air grooves can also be provided on the inner surface of the second accommodation cavity 112, so that the gas in the second accommodation cavity 112 can be discharged outside the cup body 11 through the side air grooves on the inner surface of the second accommodation cavity 112.

[0075] An exhaust passage is formed between the extrusion assembly 300 and the second accommodation cavity 112. In another embodiment, side air grooves 311 for forming the exhaust passage are formed on both the circumferential side surface of the extrusion housing 31 and the inner surface of the second accommodation cavity 112, which is convenient for the gas in the second accommodation cavity 112 to be discharged outside the cup body 11 through the side air grooves 311.

[0076] A gap for forming a temporary exhaust passage exists between the extrusion assembly 300 and the silicone part 400. In one embodiment, a through hole 41 is formed in the middle area of the silicone part 400, and the diameter of the through hole 41 is larger than the diameter of the material injection bottom end 314 of the extrusion housing 31. When the extrusion assembly 300 and the silicone part 400 are in the first positional relationship, the material injection bottom end 314 of the extrusion housing 31 is located in the through hole 41. The material injection bottom end 314 of the extrusion housing 31 refers to the end from which the solvent in the bursting bead 33 flows out of the extrusion housing 31 when the bursting bead 33 is crushed. Please refer to Figure 6 , which shows the material injection bottom end 314. The following specifically describes the temporary exhaust passage in the scenario where the extrusion assembly 300 includes an extrusion housing 31, an extrusion rod 32, and a bursting bead 33:

[0077] Please refer to Figure 10 , which shows that the extrusion rod 32 is positioned on the extrusion housing 31, the bursting bead 33 is located in the extrusion housing 31, and the extrusion housing 31 is located in the second accommodation cavity 112. At this time, the material injection bottom end 314 of the extrusion housing 31 is inserted into the through hole 41 on the silicone part 400, and there is an air passage gap 115 between the material injection bottom end 314 of the extrusion housing 31 and the through hole 41 of the silicone part 400. This state is called the first positional relationship. In Figure 10On the basis of this, press down the extrusion rod 32, and the extrusion rod 32 moves downward relative to the extrusion housing 31 to extrude the bursting bead 33 (the reason why the extrusion rod 32 moves downward relative to the extrusion housing 31 when pressing down the extrusion rod 32 will be explained below, and the position of the extrusion housing 31 remains unchanged temporarily). When the extrusion rod 32 is extruded to the position shown in Figure 11 , the solvent in the bursting bead 33 can be pressed into the first accommodating cavity 111. At the same time, the air in the extrusion housing 31 is also pressed into the first accommodating cavity 111, and the pressure in the first accommodating cavity 111 increases, so that the excess gas is discharged to the second accommodating cavity 112 through the air passage gap 115 between the material injection bottom end 314 of the extrusion housing 31 and the silica gel part 400. When continuing to press the extrusion rod 32, the extrusion rod 32 drives the extrusion housing 31 to move downward together. The gas in the second accommodating cavity 112 is squeezed and discharged to the outside through the side air groove 311. When the extrusion rod 32 drives the extrusion housing 31 to move to the position shown in Figure 12 , the operation of the extrusion assembly 300 is completed.

[0078] Regarding Figure 10 , there is a gap between the material injection bottom end 314 of the extrusion housing 31 and the through hole 41 of the silica gel part 400 in Figure 12 , and in

[0079] , the extrusion housing 31 and the silica gel part 400 are in sealed cooperation. The specific implementation method in terms of structure is as follows: Figure 8 Please refer to

[0080] , the extrusion housing 31 includes an upper housing section 312 and a lower housing section 313. One end of the upper housing section 312 is connected to one end of the lower housing section 313. The end of the lower housing section 313 far from the upper housing section 312 is the material injection bottom end 314 of the extrusion housing 31. The diameter of the outer surface of the upper housing section 312 is larger than the diameter of the outer surface of the lower housing section 313. Along the direction away from the upper housing section 312, the diameter of the lower housing section 313 gradually decreases.

[0081] Regarding the above description of pressing down the extrusion rod 32, the extrusion rod 32 moves downward relative to the extrusion housing 31 to extrude the bursting bead 33. The specific description is as follows:

[0082] Case 1: A thin film layer 42 is provided on the silicone part 400 for blocking the through hole 41.

[0083] Please refer to Figure 10 , which shows the thin film layer 42. The thin film layer 42 is connected to the circumferential side surface of the through hole 41. Regarding the position of the thin film layer 42 on the through hole 41: The silicone part 400 includes a first end face and a second end face arranged oppositely. Among them, when the extrusion housing 31 is inserted into the silicone part 400 by extrusion, the extrusion housing 31 first passes through the first end face of the silicone part 400. Preferably, the thin film layer 42 is arranged at a position in the through hole 41 close to the first end face. Of course, the thin film layer 42 can also be arranged at the middle position of the through hole 41, or the thin film layer 42 can be arranged at a position in the through hole 41 close to the second end face.

[0084] When the extrusion assembly 300 is not in use, through the silicone part 400 and the thin film layer 42 on the silicone part 400, the aerosol matrix in the cup body 11 can be sealed to prevent oil leakage from the cup body 11.

[0085] Please refer to Figure 10 , when the extrusion housing 31 is placed in the second accommodation cavity 112, the injection bottom end 314 of the extrusion housing 31 is supported on the thin film layer 42, and there is a gap between the injection bottom end 314 of the extrusion housing 31 and the through hole 41 of the silicone part 400. When the extrusion rod 32 is pressed downward, due to the supporting effect of the thin film layer 42 on the extrusion housing 31, the extrusion rod 32 moves downward relative to the extrusion housing 31 to squeeze the bursting bead 33. When the extrusion rod 32 continuously receives a downward force until the thin film layer 42 ruptures, the solvent in the bursting bead 33 and the air in the extrusion housing 31 are pressed into the first accommodation cavity 111, the pressure in the first accommodation cavity 111 increases, and the instantaneous excess gas is discharged to the second accommodation cavity 112 through the gap between the injection bottom end 314 of the extrusion housing 31 and the silicone part 400. Then the extrusion rod 32 drives the extrusion housing 31 to move downward together, and the gas in the second accommodation cavity 112 is squeezed and discharged to the outside through the side air vent groove 311. Since the thin film layer 42 is arranged on the inner side surface of the through hole 41, refer to Figure 10 , when the extrusion housing 31 is placed in the second accommodation cavity 112, the thin film layer 42 supports the extrusion housing 31 and the injection bottom end 314 of the extrusion housing 31 is located in the through hole 41. When the thin film layer 42 ruptures, since the injection bottom end 314 is located in the through hole 41, it is to prevent the solvent flowing out of the extrusion housing 31 from spraying into the second accommodation cavity 112.

[0086] Regarding the rupture time of the thin film layer 42, the rupture at different times can be realized by setting the strength of the thin film layer 42. For example, when from Figure 10 The position of the extrusion rod 32 shown is in the process of squeezing the bursting bead 33 downward. Due to the squeezing force of the solvent of the bursting bead 33 on the thin film layer 42, it may burst; or when fromFigure 10 As shown in the figure, during the process of the extrusion rod 32 extruding the bursting bead 33 downward, when the extrusion rod 32 drives the extrusion housing 31 to move downward by a certain displacement, the film layer 42 ruptures.

[0087] Regarding the specific position of the bursting bead 33 in the extrusion housing 31, based on the fact that the extrusion housing 31 includes an upper housing section 312 and a lower housing section 313, please refer to Figure 10 , an upper housing hole 316 is provided in the upper housing section 312, a lower housing hole 315 communicating with the upper housing hole 316 is provided in the lower housing section 313, the diameter of the lower housing hole 315 is smaller than that of the upper housing hole 316, the lower housing hole 315 and the upper housing hole 316 form a stepped surface, the bursting bead 33 is arranged in the upper housing hole 316 and supported on the stepped surface, and the extrusion rod 32 is inserted into the upper housing hole 316.

[0088] Please refer to Figure 10 , the bursting bead 33 is located in the upper housing hole 316. When the extrusion rod 32 moves downward, the bursting bead 33 is extruded, and the solvent flowing out after the bursting bead 33 is crushed flows downward into the lower housing hole 315.

[0089] In addition, it is preferable that the diameter of the lower housing hole 315 is smaller, so that the sheath of the bursting bead 33 will not fall into the first accommodation cavity 111 through the lower housing hole 315 when the bursting bead 33 bursts.

[0090] Case 2: The film layer 42 blocking the through hole 41 is not provided on the silica gel part 400

[0091] When the film layer 42 blocking the through hole 41 is not provided on the silica gel part 400, a positioning structure needs to be added between the second accommodation cavity 112 and the extrusion housing 31, that is, when the extrusion housing 31 is inserted into the second accommodation cavity 112, the position of the extrusion housing 31 in the second accommodation cavity 112 is limited by the positioning structure, so that the injection bottom end 314 of the extrusion housing 31 is inserted into the through hole 41 on the silica gel part 400 and there is a gap between the injection bottom end 314 of the extrusion housing 31 and the through hole 41 of the silica gel part 400. The positional relationship is as shown in Figure 10As shown. The positioning structure can be a convex-groove matching structure. When the extrusion rod 32 is pressed downward, due to the positioning structure between the extrusion housing 31 and the second accommodation cavity 112, the extrusion rod 32 moves downward relative to the extrusion housing 31 to extrude the bursting bead 33. The solvent in the bursting bead 33 and the air in the extrusion housing 31 are pressed into the first accommodation cavity 111, the pressure in the first accommodation cavity 111 increases, and the instantaneous excess gas is discharged to the second accommodation cavity 112 through the gap between the injection bottom end 314 of the extrusion housing 31 and the silica gel part 400. Then, the extrusion rod 32 contacts the step surface of the extrusion housing 31, and the extrusion rod 32 drives the extrusion housing 31 to move downward together. The gas in the second accommodation cavity 112 is squeezed and discharged to the outside of the cup body 11 through the side air vent groove 311.

[0092] The side air vent groove 311 has been described above. In one embodiment, a bottom air vent groove 317 is provided on the outer end surface of the upper housing section 312 close to the lower housing section 313, and the bottom air vent groove 317 is communicated with the side air vent groove 311 on the extrusion housing 31.

[0093] Please refer to Figure 8 , which shows the bottom air vent groove 317 provided on the extrusion housing 31. The bottom air vent groove 317 is preferably annular and communicated with the side air vent groove 311. By providing the bottom air vent groove 317, it is beneficial to guide the air flow to flow through the bottom air vent groove 317 to the side air vent groove 311 to a certain extent.

[0094] Regarding the structure of the extrusion rod 32, specifically as follows: In one embodiment, refer to Figure 9 and Figure 10 , the extrusion rod 32 includes an upper extrusion rod section 321 and a lower extrusion rod section 322. The upper extrusion rod section 321 is connected to the lower extrusion rod section 322. The diameter of the upper extrusion rod section 321 is larger than that of the lower extrusion rod section 322, and the lower extrusion rod section 322 is inserted into the upper housing hole 316.

[0095] By setting the diameter of the upper extrusion rod section 321 to be larger than that of the lower extrusion rod section 322, it is convenient to apply a force on the free end surface of the upper extrusion rod section 321.

[0096] Exemplarily, an upper side seal 34 for sealing and mating with the inner side wall of the second accommodation cavity 112 is provided on the upper extrusion rod section 321. An air vent groove 323 is provided on the circumferential side surface of the upper extrusion rod section 321. One end of the air vent groove 323 opens to the end of the upper extrusion rod section 321 close to the lower extrusion rod section 322, and the air vent groove 323 and the side air vent groove 311 on the extrusion housing 31 are arranged in sequence along the axial direction parallel to the bursting bead 33 assembly.

[0097] Please refer to Figure 12, it shows that the upper seal 34 is squeezed between the extrusion rod 32 and the inner side of the second receiving cavity 112, realizing the sealing between the upper extrusion rod section 321 of the extrusion rod 32 and the second receiving cavity 112. On the basis of the sealing between the extrusion housing 31 and the silica gel part 400, the upper seal 34 is further provided to achieve the effect of double sealing and prevent the cup body 11 from leaking oil through the second receiving cavity 112.

[0098] Please refer to Figure 9 , it shows the air vent groove 323 on the upper extrusion rod section 321. The air vent groove 323 and the side air vent groove 311 on the extrusion housing 31 are arranged in sequence along the axial direction parallel to the bead 33 assembly. That is, when the extrusion rod 32 is installed on the extrusion housing 31, the air vent groove 323 on the upper extrusion rod section 321 and the side air vent groove 311 on the extrusion housing 31 are on the same diameter, and the air vent groove 323 on the upper extrusion rod section 321 is communicated with the side air vent groove 311 on the extrusion housing 31, so that when the upper extrusion rod section 321 of the extrusion rod 32 extends into the second receiving cavity 112, the compressed gas can be discharged out of the second receiving cavity 112 through the side air vent groove 311 and the air vent groove 323 on the upper extrusion rod section 321.

[0099] Regarding the sealing between the extrusion rod 32 and the extrusion housing 31, exemplarily, an annular groove is provided on the circumferential side of the lower extrusion rod section 322, and a lower seal 35 for sealing cooperation with the extrusion housing 31 is provided in the annular groove. Please refer to Figure 9 and Figure 10 , it shows the lower seal 35. Figure 10 In, the lower seal 35 is squeezed between the extrusion rod 32 and the extrusion housing 31 to realize the sealing between the extrusion rod 32 and the extrusion housing 31 and prevent the aerosol matrix in the cup body 11 from flowing out through the gap between the extrusion housing 31 and the extrusion rod 32.
