Description

Technical Field

[0001] The present application relates to the technical field of atomization, and more particularly, to an aerosol generating device. Background Art

[0002] An aerosol generating device atomizes an atomization medium by high-temperature heating to generate an aerosol for inhalation. In an aerosol generating device, it is necessary to fix a heating element, which causes heat to be easily conducted away by the fixing device of the heating element, resulting in low heat utilization efficiency. Summary of the Invention

[0003] In view of the above problems, an embodiment of the present application provides an aerosol generating device.

[0004] The aerosol generating device according to the embodiment of the present application includes a housing assembly, an atomization assembly, and a heating assembly. The housing assembly forms an installation space; the atomization assembly is detachably connected to the housing assembly, and the atomization assembly includes an atomization chamber for accommodating an atomization medium; the heating assembly is disposed in the installation space, and the heating assembly is configured to sleeve on the atomization chamber and detach from the housing assembly when the atomization chamber is inserted into the installation space. The heating assembly includes a heat-resistant elastic member and a heating element. The heat-resistant elastic member is fixedly connected to the heating element and applies an elastic force to the heating element to make the heating element closely adhere to the atomization chamber.

[0005] In the aerosol generating device according to the embodiment of the present application, the heating assembly sleeves on the atomization chamber when the atomization chamber and the housing assembly are assembled, and can detach from the housing assembly to be in a suspended state without other fixing devices. By applying an elastic force to the heating element through the heat-resistant elastic member, while ensuring a firm connection between the heating assembly and the atomization chamber, the heating element is fully adhered to the atomization chamber. On the one hand, heat loss caused by heat transfer from the heating assembly to the outside is reduced, and on the other hand, the heat transfer effect to the atomization medium is improved, thereby enhancing the atomization effect and effectively improving the heat utilization efficiency.

[0006] In some embodiments, the housing assembly includes a first housing and a second housing that are detachably connected, and an elastic fitting connecting the first housing and the second housing. The first housing and the second housing face each other in a first direction, and the elastic fitting is configured to have a first state in which it generates compressive elastic deformation in the first direction and a second state in which the deformation is restored.

[0007] In this way, by connecting the first housing and the second housing through the elastic fitting, when the first housing and the second housing are assembled, the elastic fitting abuts against the first housing and the second housing and generates compressive elastic deformation, thereby sealing the installation space. Moreover, when the first housing and the second housing are disassembled, the elastic fitting is restored to its original shape, so that the first housing and the second housing form an elastic contact, facilitating the disassembly and assembly of the housing assembly.

[0008] In some embodiments, the atomizing component is connected to the first housing, the heating component is disposed on the second housing and is opposite to the atomizing chamber in a first direction. When the elastic fitting is in a first state, the heat-resistant elastic member abuts against the second housing; when the elastic fitting is in a second state, the heating element is separated from the second housing.

[0009] Thus, during the assembly process of the first housing and the second housing, the elastic fitting is first in the first state. The atomizing chamber moves downward and is connected to the heating component. Subsequently, the elastic fitting changes from the first state to the second state, and the elastic fitting rebounds in the first direction, pushing the first housing, the atomizing chamber, and the heating component connected to the atomizing chamber to move away from the second housing in the first direction. The heating component is separated from the second housing and is fixed in position only through the atomizing chamber. Therefore, during the assembly process of the atomizing chamber and the housing assembly, the assembly of the atomizing chamber and the heating component is also completed. The operation is simple, and the heating component is fixed in position through the atomizing chamber, reducing heat transfer to the outside.

[0010] In some embodiments, the elastic fitting is fixedly connected to one of the first housing and the second housing and is detachably connected to the other of the first housing and the second housing.

[0011] Thus, by fixedly connecting the elastic fitting to one of the first housing and the second housing and detachably connecting it to the other of the first housing and the second housing, the part integration is improved, which is beneficial to the stable force of the elastic fitting, and further ensures that the elastic fitting deforms and rebounds in a preset form.

[0012] In some embodiments, the second housing includes a base and a limiting structure. The base and the first housing together form an installation space. The limiting structure, the atomizing component, and the heating component are all disposed in the installation space. The elastic fitting is clamped in the assembly gap between the base and the first housing. The limiting structure is used to limit the movement range of the heating component when the heating component abuts against the atomizing chamber.

[0013] Thus, by clamping the elastic fitting in the assembly gap between the base and the first housing, the elastic fitting deforms and rebounds when the first housing is installed on the base, improving the synchronization of the movement of the first housing with the deformation and rebound of the elastic fitting. By limiting the movement range of the heating component through the limiting structure, the heating component can complete the connection with the atomizing chamber and the separation from the second housing, or complete the connection with the second housing and the separation from the atomizing chamber within a preset movement range.

[0014] In some embodiments, the limiting structure includes a first limiting portion and a second limiting portion that are spaced apart and opposite in a first direction. The interval between the first limiting portion and the second limiting portion that are spaced apart and opposite forms a limiting groove, and the heat-resistant elastic member is accommodated in the limiting groove.

[0015] In this way, by arranging the first limiting part and the second limiting part at intervals and oppositely along the first direction, and accommodating the heat-resistant elastic part in the limiting groove formed between the first limiting part and the second limiting part, the heat-resistant elastic part can move up and down along the first direction in the limiting groove. As a result, the first limiting part, the limiting groove, and the second limiting part respectively limit the positions of the heat-resistant elastic part and the heating element in the first direction to the first position state, the second position state, and the third position state.

[0016] In some embodiments, the heating assembly has a first position state. In the first position state, the elastic fitting is in the first state, and the first limiting part abuts against the heat-resistant elastic part upward along the first direction so that the heating element is in close contact with the atomization chamber; and / or, the heating assembly has a second position state. In the second position state, the elastic fitting is in the second state, and the heat-resistant elastic part is connected to the atomization chamber and suspended in the limiting groove; and / or, the heating assembly has a third position state. In the third position state, the second limiting part can abut against the heat-resistant elastic part downward along the first direction so that the heating element is separated from the atomization chamber.

[0017] In this way, when the heating assembly is in the first position state, the first limiting part abuts against the heat-resistant elastic part upward until the heating element is in close contact with the atomization chamber, thereby ensuring a reasonable position of the heat-resistant elastic part sleeved on the atomization chamber, and the heating element is in contact with the atomization chamber neither too tightly nor too loosely. After the heating element is in close contact with the atomization chamber, the first limiting part abuts against the heat-resistant elastic part upward, causing the heating assembly and the atomization chamber to have a tendency to move upward along the first direction. As a result, the first housing relaxes the extrusion on the elastic fitting, and the elastic fitting can rebound and change from the first state to the second state.

[0018] When the elastic fitting changes from the first state to the second state, the heating assembly moves from the first position state to the second position state, so that the heating element remains in contact with the atomization chamber and is separated from the second housing, and the heat-resistant elastic part is connected to the atomization chamber and suspended in the limiting groove, thereby reducing heat transfer to components other than the atomization chamber and improving heat utilization efficiency.

[0019] When the heating assembly moves upward to the third position state, the second limiting part abuts against the heat-resistant elastic part downward, pushing the heating element and the heat-resistant elastic part away from the atomization chamber, thereby simplifying the operation of disassembling and replacing the atomization chamber.

[0020] In some embodiments, the limiting structure is a limiting plate erected on the second housing. The limiting plate forms an accommodating hole communicating with the limiting groove. The first limiting part and the second limiting part surround the accommodating hole, and at least a part of the heating element and the atomization chamber is accommodated in the accommodating hole.

[0021] In this way, at least a part of the heating element and the atomization chamber are accommodated through the accommodation hole, and the first limiting portion and the second limiting portion surround the accommodation hole, thereby effectively utilizing the space of the accommodation plate and ensuring that the heating component can be limited in all positions in the circumferential direction.

[0022] In some embodiments, the heat-resistant elastic member is in an open-ring shape and is accommodated in the limiting groove. When the heating component is in the first position state, the heat-resistant elastic member generates circumferential elastic deformation and sleeves on the atomization chamber, so that the heating element is in close contact with the atomization chamber. When the heating component is in the second position state, the heating element is in close contact with the atomization chamber and floats in the accommodation hole.

[0023] In this way, since the heat-resistant elastic member is in an open-ring shape and deforms at the opening, the size of the opening can be enlarged when the atomization chamber approaches the heat-resistant elastic member. Thus, the heat-resistant elastic member can sleeve on the atomization chamber and apply an elastic force to the atomization chamber, ensuring stable connection and synchronous movement between the heating component and the atomization chamber. Furthermore, the heating element can remain in close contact with the atomization chamber and float in the accommodation hole, reducing heat transfer to components other than the atomization chamber and improving heat utilization efficiency.

[0024] In some embodiments, a plurality of notches are formed on the side of the heat-resistant elastic member facing the atomization chamber in the radial direction.

[0025] In this way, by forming a plurality of notches on the side of the heat-resistant elastic member facing the atomization chamber in the radial direction, the contact area between the heat-resistant elastic member and the atomization chamber is reduced, and further heat loss on the heat-resistant elastic member is reduced.

[0026] In some embodiments, the heating element includes a main body portion and a connecting portion. The main body portion is in a hollow disk-shaped structure and is accommodated in the accommodation hole. The main body portion is connected to a plurality of connecting portions, and the plurality of connecting portions are arranged at intervals along the circumference of the main body portion. The connecting portion extends upward from the main body portion in the first direction to the heat-resistant elastic member.

[0027] In this way, by forming the main body portion into a hollow disk shape, the resistance heating power is increased. By connecting the heat-resistant elastic member through a plurality of spaced-apart connecting portions, heat transfer from the main body portion to the heat-resistant elastic member is reduced.

[0028] In some embodiments, the surface of the atomization chamber in contact with the heat-resistant elastic member forms an angle with the first direction.

[0029] In this way, since the surface of the atomization chamber in contact with the heat-resistant elastic member forms an angle with the first direction, the atomization chamber can squeeze the heat-resistant elastic member in the circumferential direction and cause the heat-resistant elastic member to deform during the movement in the first direction, thereby ensuring the smooth disassembly and assembly of the atomization chamber.

[0030] In some embodiments, the atomization assembly further includes an airway seal. The airway seal is fixedly and sealingly connected to the atomization chamber, and the housing assembly is formed with a mouthpiece. The airway seal communicates with the mouthpiece to form a suction airway.

[0031] In this way, by fixedly and sealingly connecting the airway seal with the atomization chamber, the components of the atomization assembly are connected as a whole, which is convenient for replacement and ensures that the aerosol in the suction airway is not easily leaked and is not easily polluted by the external environment.

[0049] The aerosol generating device 100 is a structure capable of generating an aerosol in an atomization medium by at least one of the methods such as resistive heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical oscillation. The atomization medium is a substance that has been processed and can generate an aerosol after being heated. The atomization medium is atomized by heat to form an aerosol. The aerosol can be visible or invisible and can include vapor (for example, fine particulate matter in a gaseous state, which is usually a liquid or a solid at room temperature), as well as liquid droplets of gas and condensed vapor. The aerosol may contain volatile compounds. The user can inhale the aerosol into the mouth, nasal cavity, or lungs through the mouth or nose. The aerosol inhaled into the user's respiratory system can be used for various purposes such as consumption, medicine, health care, and entertainment.

[0050] The form of the atomization medium can be all-solid or semi-solid, or it can be liquid. For example, the solid atomization medium can be a product of the flower, stem or leaf of a plant prepared by processes such as roll pressing, thick slurry, die casting, extrusion, etc. Another example is that the liquid atomization medium can include a liquid composition based on plant extracts and / or various flavoring agents.

[0051] Please refer to Figures 1-4 , the aerosol generating device 100 according to the embodiment of the present application includes a housing assembly 10, an atomization assembly 20 and a heating assembly 30. The housing assembly 10 forms an installation space 101; the atomization assembly 20 is detachably connected to the housing assembly 10, and the atomization assembly 20 includes an atomization chamber 21 for accommodating the atomization medium; the heating assembly 30 is disposed in the installation space 101, and the heating assembly 30 is configured to be sleeved on the atomization chamber 21 and separated from the housing assembly 10 when the atomization chamber 21 is inserted into the installation space 101. The heating assembly 30 includes a heat-resistant elastic member 31 and a heating element 32. The heat-resistant elastic member 31 is fixedly connected to the heating element 32 and applies an elastic force to the heating element 32 to make the heating element 32 closely adhere to the atomization chamber 21.

[0052] In the aerosol generating device 100 according to the embodiment of the present application, the heating assembly 30 is sleeved on the atomization chamber 21 when the atomization chamber 21 and the housing assembly 10 are assembled, and can be separated from the housing assembly 10 to be in a suspended state without other fixing devices. By applying an elastic force to the heating element 32 through the heat-resistant elastic member 31, while ensuring the firm connection between the heating assembly 30 and the atomization chamber 21, the heating element 32 is fully adhered to the atomization chamber 21. On the one hand, the heat loss caused by the heat transfer of the heating assembly 30 to the outside is reduced, and on the other hand, the heat transfer effect to the atomization medium is improved, thereby enhancing the atomization effect and effectively improving the thermal utilization rate.

[0053] Specifically, the atomization chamber 21 can be a hollow cylinder, and the atomization chamber 21 can be in a columnar shape, a conical shape, a capsule shape or other composite structures. The cross-sectional and longitudinal-sectional shapes of the atomization chamber 21 can be circular, elliptical, triangular, square, rhombic, polygonal, star-shaped, racetrack-shaped or other irregular shapes, and the present application does not limit this. The present application takes the cylindrical atomization chamber 21 provided in some embodiments as an example for illustration. As shown in the figure, one end of the atomization chamber 21 in its own axial direction forms an opening 210, and the other end forms a closed bottom. In this embodiment, the atomization medium can be a semi-solid substance such as paste or mush, and is coated on the inner surface of the bottom of the atomization chamber 21.

[0054] The heating element 32 is an element that can generate heat by at least one of the ways such as resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical oscillation. Exemplarily, the heating element 32 is heated based on the principle of resistance heating. The heating element 32 has conductivity and can convert electrical energy into heat energy when energized.

[0055] The heat-resistant elastic member 31 is fixedly connected to the heating element 32 by at least one of the ways of snap connection, welding, riveting, screwing, glue connection, fixing member connection, etc. Exemplarily, the heat-resistant elastic member 31 is snap-connected to the heating element 32.

[0056] Please continue to refer to Figures 1-4 , in some embodiments, the housing assembly 10 includes a first housing 11 and a second housing 12 that are detachably connected, and an elastic fitting 13 that connects the first housing 11 and the second housing 12. The first housing 11 and the second housing 12 face each other in the first direction, and the elastic fitting 13 is configured to have a first state in which it generates compressive elastic deformation in the first direction and a second state in which the deformation is restored.

[0057] In this way, by connecting the first housing 11 and the second housing 12 through the elastic fitting 13, when the first housing 11 and the second housing 12 are assembled, the elastic fitting 13 abuts against the first housing 11 and the second housing 12 and generates compressive elastic deformation, thereby playing a sealing role for the installation space 101. And when the first housing 11 and the second housing 12 are disassembled, the elastic fitting 13 is deformed and restored, so that the first housing 11 and the second housing 12 form an elastic contact, which is convenient for the disassembly and assembly of the housing assembly 10.

[0058] Specifically, both the first housing 11 and the second housing 12 are hollow structures. The first housing 11 and the second housing 12 face each other and are connected in the first direction. The hollow intervals inside the first housing 11 and the second housing 12 can communicate with each other and form an installation space 101. For the convenience of description, in the following description, the direction from the first housing 11 pointing to the second housing 12 in the first direction is defined as the direction from top to bottom. The atomization chamber 21 is arranged in the installation space 101 with its axial direction parallel to the first direction, and one end of the atomization chamber 21 with an opening 210 is located above. In some other examples, the atomization chamber 21 can also be arranged in an orientation forming an angle with the first direction.

[0059] The first housing 11 and the second housing 12 can be connected by at least one of the ways of snap connection, threaded connection, fixing member connection, glue connection, etc. Exemplarily, the first housing 11 and the second housing 12 are snap-connected, and the lower end of the first housing 11 and the upper end of the second housing 12 are buckled. The materials of the first housing 11 and the second housing 12 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not make special restrictions on this.

[0060] The elastic fitting 13 is disposed between the first housing 11 and the second housing 12. The upper side surface of the elastic fitting 13 is connected to the first housing 11, and the lower side surface is connected to the second housing 12. When the housing assembly 10 starts to be assembled, the first housing 11 and the second housing 12 approach each other in the first direction, squeezing the elastic fitting 13 from the upper side surface and the lower side surface respectively. The elastic fitting 13 is compressed in the first direction, so that the elastic fitting 13 is in the first state as shown in Figure 6 . When the first housing 11 and the second housing 12 are assembled, the elastic fitting 13 rebounds and changes from the first state to the second state as shown in Figure 3 . It should be noted that when the elastic fitting 13 is in the second state, the first housing 11 and the second housing 12 remain connected, and the elastic fitting 13 is still subjected to the squeezing force applied by the first housing 11 and the second housing 12, with a certain amount of compressive deformation, but the degree of compressive deformation is smaller than that in the first state.

[0061] When the housing assembly 10 is disassembled, the first housing 11 and the second housing 12 move away from each other in the first direction until they are completely separated, and the elastic fitting 13 returns to its deformed state to the natural state as shown in Figure 7 . It can be understood that the width of the elastic fitting 13 in the first direction increases in sequence from the first state, the second state to the natural state.

[0062] Please refer to Figures 2-4 . In some embodiments, the atomization assembly 20 is connected to the first housing 11, the heating assembly 30 is disposed on the second housing 12 and is opposite to the atomization chamber 21 in the first direction. When the elastic fitting 13 is in the first state, the heat-resistant elastic member 31 abuts against the second housing 12; when the elastic fitting 13 is in the second state, the heating element 32 is separated from the second housing 12.

[0063] In this way, during the assembly process of the first housing 11 and the second housing 12, the elastic fitting 13 is first in the first state, the atomization chamber 21 moves downward and is connected to the heating assembly 30. Subsequently, the elastic fitting 13 changes from the first state to the second state, and the elastic fitting 13 rebounds in the first direction, pushing the first housing 11, the atomization chamber 21 and the heating assembly 30 connected to the atomization chamber 21 to move away from the second housing 12 in the first direction. The heating assembly 30 is separated from the second housing 12 and is fixed only by the atomization chamber 21. Thus, during the assembly process of the atomization chamber 21 and the housing assembly 10, the assembly of the atomization chamber 21 and the heating assembly 30 is also completed. The operation is simple, and the heating assembly 30 is fixed only by the atomization chamber 21, reducing the heat transfer to the outside.

[0064] Specifically, the first housing 11 and the atomization assembly 20 can be integrally connected by a silicone-based elastic seal to form an airtight air flow channel. The heating assembly 30 is movably disposed relative to the second housing 12.

[0065] During the assembly process of the first housing 11, the atomization component 20 and the second housing 12, the atomization chamber 21 is first fixedly installed in the first housing 11 through elastic sealing, and the heating component 30 is installed on the second housing 12; the first housing 11 and the atomization component 20 as a whole move downward in the first direction to approach the second housing 12, and the elastic fitting 13 is squeezed and contracts and deforms in the first direction, from the natural state as shown in Figure 7 to gradually change to the first state as shown in Figure 6 . In this step, the atomization component 20 moves with the first housing 11 and approaches the heating component 30, and the atomization chamber 21 can be aligned with the heating component 30 in the first direction; when the elastic fitting 13 reaches the first state, the first housing 11 and the second housing 12 are snapped together, the heating component 30 is sleeved on the atomization chamber 21, and the heating element 32 is pressed against the bottom of the atomization chamber 21. At this time, the heating component 30 and the atomization chamber 21 are connected together and can move as a whole; subsequently, the elastic fitting 13 resumes deformation and changes from the first state to the second state as shown in Figure 3 . In this step, the elastic fitting 13 provides a resilience force to push the first housing 11, the atomization component 20 and the heating component 30 to move upward as a whole, the heating component 30 is separated from the second housing 12, and the first housing 11 and the second housing 12 remain snap-connected.

[0066] It can be understood that the distance of the elastic fitting 13 rebounding during the process of changing from the first state to the second state is less than the distance of contraction during the process of changing from the natural state to the first state at the beginning of assembly, so as to ensure that the first housing 11 and the second housing 12 will not be separated during rebounding.

[0067] In some embodiments, the elastic fitting 13 is fixedly connected to one of the first housing 11 and the second housing 12 and detachably connected to the other of the first housing 11 and the second housing 12.

[0068] In this way, by fixedly connecting the elastic fitting 13 to one of the first housing 11 and the second housing 12 and detachably connecting it to the other of the first housing 11 and the second housing 12, the part integration is improved, which is beneficial to the stable force of the elastic fitting 13, and further ensures that the elastic fitting 13 deforms and rebounds in a preset form.

[0069] For example, the elastic fitting 13 is a rubber ring, and the rubber ring can be pre-sleeved on the base 121 and reinforced by adhesives or the like.

[0070] Another example is that the elastic fitting 13 is a rubber ring, and the rubber ring is fixedly connected to the first housing 11 to form a whole and moves as a whole until it is installed on the second housing 12.

[0071] In the above embodiments, when the first housing 11 is engaged with the second housing 12, the first housing 11 presses the rubber ring downward, and the second housing 12 presses the rubber ring upward.

[0072] Please refer to Figures 2-4 , in some embodiments, the second housing 12 includes a base 121 and a limiting structure 122. The base 121 and the first housing 11 together form an installation space 101. The limiting structure 122, the atomization assembly 20, and the heating assembly 30 are all arranged in the installation space 101. The elastic fitting 13 is clamped in the assembly gap between the base 121 and the first housing 11. The limiting structure 122 is used to limit the movement range of the heating assembly 30 when the heating assembly 30 abuts against the atomization chamber 21.

[0073] In this way, by clamping the elastic fitting 13 in the assembly gap between the base 121 and the first housing 11, the elastic fitting 13 deforms and rebounds when the first housing 11 is installed on the base 121, improving the synchronization of the movement of the first housing 11 with the deformation and rebound of the elastic fitting 13. By limiting the movement range of the heating assembly 30 through the limiting structure 122, the heating assembly 30 can complete the connection with the atomization chamber 21 and the disengagement from the second housing 12, or complete the connection with the second housing 12 and the disengagement from the atomization chamber 21 within a preset movement range.

[0074] Specifically, the lower end of the first housing 11 forms an open port, and a reverse buckle 112 is formed on the side of the lower end of the first housing 11 facing the installation space 101. In the second housing 12, an open installation port 1211 is also formed at the upper end of the base 121. A convex edge 1212 protruding away from the installation space 101 is provided at the upper end of the base 121. The convex edge 1212 can surround the installation port 1211. The upper end of the base 121 can extend into the inner side of the lower end of the first housing 11, and the reverse buckle 112 of the first housing 11 and the convex edge 1212 of the base 121 are engaged with each other. A stepped surface 1214 is formed on the outer side of the base 121 near the installation port 1211. When the upper end surface of the base 121 extends into the first housing 11, the stepped surface 1214 and the lower end surface of the first housing 11 are opposite and spaced apart in the first direction. The elastic fitting 13 is a rubber ring and can be arranged between the stepped surface 1214 and the upper end surface.

[0075] The limiting structure 122 is installed at the installation opening 1211 of the base 121. The limiting structure 122 can be fixedly connected to the base 121 by at least one of welding, threaded connection, riveting, snap connection, gluing connection, connection with fixing parts, etc. Exemplarily, a snap groove 1213 is formed on the inner wall surface of the base 121 at the installation opening 1211. The limiting structure 122 is formed with a rib 1226. The limiting structure 122 is fixedly installed inside the base 121 by engaging the rib 1226 with the snap groove 1213. When the heating component 30 is separated from the atomizing component 20, the heating component 30 abuts against the limiting structure 122 and is placed at the installation opening 1211 of the base 121 through the limiting structure 122.

[0076] Please refer to Figures 3-7 , in some embodiments, the limiting structure 122 includes a first limiting portion 1221 and a second limiting portion 1222 that are spaced apart and opposite to each other in a first direction. A limiting groove 1223 is formed in the interval where the first limiting portion 1221 and the second limiting portion 1222 are spaced apart and opposite to each other. The heat-resistant elastic member 31 is accommodated in the limiting groove 1223.

[0077] In this way, by the first limiting portion 1221 and the second limiting portion 1222 being spaced apart and opposite to each other in the first direction, and accommodating the heat-resistant elastic member 31 in the limiting groove 1223 formed between the first limiting portion 1221 and the second limiting portion 1222, the heat-resistant elastic member 31 moves up and down in the limiting groove 1223 in the first direction. Thus, the first limiting portion 1221, the limiting groove 1223, and the second limiting portion 1222 jointly limit the position range of the heat-resistant elastic member 31 and the heating element 32 in the first direction.

[0078] Specifically, the first limiting portion 1221 is arranged below the second limiting portion 1222. The heat-resistant elastic member 31 is arranged in the limiting groove 1223. The first limiting portion 1221 defines the lower limit position of the movement of the heat-resistant elastic member 31 in the limiting groove 1223, and the second limiting portion 1222 defines the upper limit position of the movement of the heat-resistant elastic member 31 in the limiting groove 1223. The first limiting portion 1221 and the second limiting portion 1222 can be one of structures such as bumps, flanges, blocks, rods, sleeves, planes, or inclined planes, and the present application does not limit this.

[0079] Please refer to Figure 3 , Figure 6 and Figure 7, in some embodiments, the heating component 30 has a first position state. In the first position state, the elastic fitting 13 is in a first state, and the first limiting portion 1221 abuts against the heat-resistant elastic member 31 upward along a first direction so that the heating element 32 is in close contact with the atomization chamber 21; and / or, the heating component 30 has a second position state. In the second position state, the elastic fitting 13 is in a second state, and the heat-resistant elastic member 31 is connected to the atomization chamber 21 and suspended in the limiting groove; and / or, the heating component 30 has a third position state. In the third position state, the second limiting portion 1222 can abut against the heat-resistant elastic member 31 downward along the first direction so that the heating element 32 is separated from the atomization chamber 21.

[0080] That is to say, the heating component 30 successively has a first position state (as shown in Figure 6 ), a second position state (as shown in Figure 3 ), and a third position state (as shown in Figure 7 ) along the first direction.

[0081] Before the atomization component 20 and the heating component 30 are assembled and after they are disassembled, the heat-resistant elastic member 31 can abut against the first limiting portion 1221 to limit the heating component 30 in the first position state as shown in Figure 6 . During the assembly process of the atomization component 20 and the heating component 30, the heat-resistant elastic member 31 is supported by the first limiting portion 1221 in the first position state, compresses the outer wall surface of the atomization chamber 21, and is assembled with the atomization component 20.

[0082] When the atomization component 20 and the heating component 30 are assembled, the heating component 30 and the atomization component 20 form an integral body, and the heating component 30 moves from the first position state as shown in Figure 6 to the second position state as shown in Figure 3 . When the heating component 30 is in the second position state, the heat-resistant elastic member 31 can be engaged with the atomization chamber 21 and suspended in the limiting groove 1223.

[0083] During the disassembly process of the atomization component 20 and the heating component 30, the heating component 30 first moves upward with the atomization component 20, moves from the second position state as shown in Figure 3 to the third position state as shown in Figure 7 . The heat-resistant elastic member 31 abuts against the second limiting portion 1222 in the third position state, and the heating component 30 is pushed by the second limiting portion 1222 to disengage from the outer surface of the atomization chamber 21.

[0084] In this way, when the heating component 30 is in the first position state, the first limiting portion 1221 abuts against the heat-resistant elastic member 31 upward until the heating element 32 abuts tightly against the atomization chamber 21, thereby ensuring a reasonable position of the heat-resistant elastic member 31 sleeved on the atomization chamber 21, and the fitting of the heating element 32 and the atomization chamber 21 is neither too tight nor too loose.

[0085] After the heating element 32 abuts tightly against the atomization chamber 21, the first limiting portion 1221 abuts against the heat-resistant elastic member upward, so that the heating component 30 and the atomization chamber 21 have a tendency to move upward in the first direction, thereby the first housing 11 relaxes the extrusion on the elastic fitting 13, and the elastic fitting 13 rebounds and changes from the first state to the second state.

[0086] Specifically, during the assembly of the atomization assembly 20 with the first housing 11 and the second housing 12, the atomization assembly 20 moves downward with the first housing 11, and the bottom of the atomization chamber 21 gradually approaches and contacts the heating component 30. The downward pressure of the first housing 11 and the upward supporting force of the first limiting portion 1221 jointly push the heat-resistant elastic member 31 to engage with the atomization chamber 21, driving the heating element 32 to fit against the outer surface of the bottom of the atomization chamber 21. Subsequently, when the external force on the first housing 11 is removed, during the recovery deformation process of the elastic fitting 13 changing from the first state to the second state, stress is released, pushing the first housing 11, the atomization chamber 21, and the heating component 30 attached to the bottom of the atomization chamber 21 upward, and the heat-resistant elastic member 31 is separated from the first limiting portion 1221.

[0087] Please refer to Figure 3 , in some embodiments, when the heating component 30 is in the second position state, the elastic fitting 13 is in the second state, and the heat-resistant elastic member 31 is connected to the atomization chamber 21 and suspended in the limiting groove.

[0088] In this way, the elastic fitting 13 changes from the first state to the second state, and the heating component 30 moves from the first position state to the second position state, so that the heating element 32 remains in contact with the atomization chamber 21 and is separated from the second housing 12, and the heat-resistant elastic member 31 is connected to the atomization chamber 21 and suspended in the limiting groove 1223, thereby reducing heat transfer to components other than the atomization chamber 21 and improving heat utilization efficiency.

[0089] Specifically, during the process of the aerosol generating device 100 using the heating component 30 to heat the atomization medium in the atomization chamber 21 to generate aerosol for the user to inhale, the heating component 30 remains in the second position state.

[0090] Please refer to Figure 7 , in some embodiments, when the heating component is in the third position state, the second limiting portion 1222 abuts against the heat-resistant elastic member 31 downward along the first direction, so that the heating element 32 is separated from the atomization chamber 21.

[0091] In this way, when the second limiting part 1222 drives the heating component 30 to move upward to the third position state in the atomization chamber 21, it abuts downward against the heat-resistant elastic part 31, pushing the heating element 32 and the heat-resistant elastic part 31 away from the atomization chamber 21, thus simplifying the operation of disassembling and replacing the atomization chamber 21.

[0092] Specifically, during the process of disassembling the atomization assembly 20 together with the first housing 11 and the second housing 12, the atomization assembly 20 moves upward with the first housing 11, the heat-resistant elastic part 31 gradually moves to the third position state and abuts against the second limiting part 1222. The atomization chamber 21 is subjected to an upward pulling force from the first housing 11, and the heat-resistant elastic part 31 is subjected to a downward supporting force from the second limiting part 1222, jointly pushing the atomization chamber 21 away from the heat-resistant elastic part 31, and the heating element 32 also disengages from the surface of the atomization chamber 21. During the above process, the elastic fitting 13 changes from the second state to the natural state.

[0093] In usage scenarios such as when the atomization chamber 21 reaches the end of its service life, the user needs to use different types of atomization media, or when the stock of the atomization media is insufficient and needs to be replenished, etc., the atomization chamber 21 can move with the first housing 11 and disengage from the heating component 30 during the process of disassembling the first housing 11 and the second housing 12. After installing a new atomization chamber 21 on the first housing 11, repeat the assembly steps to complete the replacement of the atomization chamber 21, and the operation is simple.

[0094] Please refer to Figures 4-7 , in some embodiments, the limiting structure 122 is a limiting plate 1224 erected on the second housing 12. The limiting plate 1224 forms an accommodating hole 1225 communicating with the limiting groove 1223. The first limiting part 1221 and the second limiting part 1222 surround the accommodating hole 1225, and at least a part of the heating element 32 and the atomization chamber 21 are accommodated in the accommodating hole 1225.

[0095] In this way, by accommodating at least a part of the heating element 32 and the atomization chamber 21 in the accommodating hole 1225, and the first limiting part 1221 and the second limiting part 1222 surround the accommodating hole 1225, the space of the accommodating plate can be effectively utilized, and it can ensure that the heating component 30 can be limited in all positions in the circumferential direction.

[0096] Specifically, the accommodating hole 1225 can be a through hole and penetrate through the upper and lower surfaces of the limiting plate 1224, and the heating element 32 can partially pass through the accommodating hole 1225 and extend below the lower surface of the limiting plate 1224.

[0097] The cross-sectional shape of the limiting plate 1224 matches the cross-sectional shape of the base 121. For example, refer to Figure 4, the cross-sectional shapes of the limiting plate 1224 and the base 121 are both runway-shaped. A ring of convex ribs 1226 is formed on the outer peripheral surface of the limiting plate 1224, and the convex ribs 1226 are engaged with the engaging grooves 1213 on the inner wall surface of the second housing 12, so that the limiting plate 1224 is erected at the mounting opening 1211.

[0098] The accommodating hole 1225 communicates with the limiting groove 1223. The limiting groove 1223 may be recessed from the peripheral wall of the accommodating hole 1225. The first limiting portion 1221 and the second limiting portion 1222 respectively surround the accommodating hole 1225 on the upper and lower surfaces of the limiting plate 1224. The limiting groove 1223 is formed inside the accommodating plate. When the thicknesses of the first limiting portion 1221 and the second limiting portion 1222 are the same, the limiting groove 1223 surrounds the accommodating hole 1225 at the middle position between the upper and lower surfaces of the limiting plate 1224.

[0099] In some other examples, the accommodating hole 1225 may also be a blind hole and is opened on the upper surface of the limiting plate 1224. The bottom of the accommodating hole 1225 is closed or semi-closed and serves as the first limiting portion 1221.

[0100] Please refer to Figures 4-8 , in some embodiments, the heat-resistant elastic member 31 is in an open-ring shape and is accommodated in the limiting groove 1223. When the heating assembly 30 is in the first position state, the heat-resistant elastic member 31 generates a circumferential elastic deformation and sleeves on the atomization chamber 21, so that the heating element 32 is tightly attached to the atomization chamber 21. When the heating assembly 30 is in the second position state, the heating element 32 is tightly attached to the atomization chamber 21 and floats in the accommodating hole 1225.

[0101] In this way, since the heat-resistant elastic member 31 is in an open-ring shape and deforms at the opening 311, the size of the opening 311 can be enlarged when the atomization chamber 21 approaches the heat-resistant elastic member 31. Thus, the heat-resistant elastic member 31 can sleeve on the atomization chamber 21 and apply an elastic force to the atomization chamber 21, ensuring stable connection and synchronous movement between the heating assembly 30 and the atomization chamber 21. Furthermore, the heating element 32 can be kept tightly attached to the atomization chamber 21 and float in the accommodating hole 1225, reducing heat transfer to components other than the atomization chamber 21 and improving heat utilization efficiency.

[0102] Specifically, the heat-resistant elastic member 31 can be coaxial with the atomization chamber 21, and the bottom of the atomization chamber 21 extends into the center of the heat-resistant elastic member 31. The heat-resistant elastic member 31 can be an annular clip and form an opening 311 to clamp the bottom of the atomization chamber 21. The inner diameter of the heat-resistant elastic member 31 without external force is slightly smaller than the outer diameter of the atomization chamber 21. When the heating assembly 30 is in the first position state, it is affected by the first limiting portion 1221 and the atomization chamber 21, and the heat-resistant elastic member 31 undergoes circumferential elastic deformation, the opening 311 expands, the circumference of the heat-resistant elastic member 31 increases and can be sleeved on the atomization chamber 21, and the heat-resistant elastic member 31 exerts a centripetal elastic force on the atomization chamber 21, so that the heat-resistant elastic member 31 and the heating element 32 press against the outer wall of the atomization chamber 21.

[0103] As Figure 3 shown, when the heating assembly 30 is in the second position state, the heat-resistant elastic member 31 clamps the atomization chamber 21 and floats in the limiting groove 1223, the heating element 32 is in close contact with the atomization chamber 21 and floats in the accommodating hole 1225, and the part of the heat-resistant elastic member 31 connected to the heating element 32 can partially float in the limiting groove 1223 or the accommodating hole 1225.

[0104] As Figure 7 shown, when the heating assembly 30 is in the third position state, the second limiting portion 1222 abuts against the heat-resistant elastic member 31 downward, the heat-resistant elastic member 31 slips off from the bottom of the atomization chamber 21 and recovers its deformation, the opening 311 shrinks, and the heat-resistant elastic member 31 drives the heating element 32 to separate from the atomization chamber 21.

[0105] Please refer to Figure 5 and Figure 8 In some embodiments, a plurality of notches 312 are formed on one side of the heat-resistant elastic member 31 facing the atomization chamber 21 in the radial direction.

[0106] In this way, by forming a plurality of notches 312 on one side of the heat-resistant elastic member 31 facing the atomization chamber 21 in the radial direction, the contact area between the heat-resistant elastic member 31 and the atomization chamber 21 is reduced, and further the heat loss on the heat-resistant elastic member 31 is reduced.

[0107] Specifically, when the heat-resistant elastic member 31 is sleeved on the atomization chamber 21, the inner circumference of the heat-resistant elastic member 31 faces the atomization chamber 21 and is partially pressed against the atomization chamber 21. The inner diameter of the heat-resistant elastic member 31 at the notch 312 is larger than the outer diameter of the atomization chamber 21, and the heat-resistant elastic member 31 at the notch 312 does not contact the atomization chamber 21. The notch 312 can extend along the circumferential direction of the heat-resistant elastic member 31 into an arc shape, or can be in various shapes such as a fan shape, a square shape, a semi-circular shape, and a semi-elliptical shape.

[0108] Please refer to Figure 4 and Figure 8, in some embodiments, the heating element 32 includes a main body portion 321 and connecting portions 322. The main body portion 321 is a hollow disc-shaped structure and is received in the receiving hole 1225. The main body portion 321 is connected to a plurality of connecting portions 322, and the plurality of connecting portions 322 are arranged at intervals along the circumference of the main body portion 321. The connecting portions 322 extend upward from the main body portion 321 in a first direction to the heat-resistant elastic member 31.

[0109] In this way, by forming the main body portion 321 into a hollow disc shape, the resistance heating power is increased. By connecting the heat-resistant elastic member 31 through a plurality of connecting portions 322 arranged at intervals, the heat transfer from the main body portion 321 to the heat-resistant elastic member 31 is reduced.

[0110] Specifically, the heating assembly 30 is sleeved on the atomization chamber 21. The main body portion 321 is closely attached to the bottom of the atomization chamber 21. The connecting portions 322 are opposite to the bottom of the atomization chamber 21 and do not contact the wall surface of the atomization chamber 21. The main body portion 321 is a thin sheet or thin plate structure, and the shape of the main body portion 321 matches the cross-sectional shape of the atomization chamber 21. For example, the main body portion 321 is circular as shown in Figure 8 shown. The main body portion 321 is formed with a plurality of hollow portions or through holes, so that when the heating element 32 is powered on, the resistance of the main body portion 321 increases, and the heating power is improved. The connecting portions 322 can be strip-shaped. The connecting portions 322 extend from bottom to top and pass through the notch 312 and extend into the heat-resistant elastic member 31. The extending ends of the connecting portions 322 can be hook-shaped and engaged with the heat-resistant elastic member 31. Four connecting portions 322 that are radially opposite to each other in pairs can be provided on the circular main body portion 321 to improve the structural stability.

[0111] Please refer to Figure 6 and Figure 7 , the heat-resistant elastic member 31 and the main body portion 321 move synchronously in the first direction and maintain a fixed height difference. While the heat-resistant elastic member 31 moves up and down in the limiting groove 1223, the main body portion 321 moves up and down in the receiving hole 1225. When the heat-resistant elastic member 31 abuts against the first limiting structure 122, the main body portion 321 can extend out of the receiving hole 1225 and be lower than the lower surface of the limiting plate 1224.

[0112] Please refer to Figure 3 , in some embodiments, the surface of the atomization chamber 21 that abuts against the heat-resistant elastic member 31 forms an angle with the first direction.

[0113] In this way, by the surface of the atomization chamber 21 that abuts against the heat-resistant elastic member 31 forming an angle with the first direction, when the atomization chamber 21 moves in the first direction, it can squeeze the heat-resistant elastic member 31 in the circumferential direction and cause the heat-resistant elastic member 31 to deform, thereby ensuring the smooth disassembly and assembly of the atomization chamber 21.

[0114] Specifically, the outer surface of the bottom of the atomization chamber 21 can be an arc surface, or there is a rounded corner at the connection between the bottom of the atomization chamber 21 and the side wall of the atomization chamber 21. It is easy to understand that the heat-resistant elastic member 31 is subjected to the supporting force or thrust of the first limiting portion 1221 and the second limiting portion 1222 in the first direction, and is subjected to the acting force perpendicular to the surface direction in contact with the atomization chamber 21, thereby generating elastic deformation. In order to enable the heat-resistant elastic member 31 to expand or contract and deform circumferentially at the opening 311, the surface of the atomization chamber 21 in contact with the heat-resistant elastic member 31 forms an angle with the first direction, so as to form a component force along the circumferential or radial direction of the heat-resistant elastic member 31, and when the atomization chamber 21 approaches and sleeves the heat-resistant elastic member 31 from top to bottom, it pushes the heat-resistant elastic member 31 to deform.

[0115] Please refer to 2- Figure 4 In some embodiments, the atomization assembly 20 further includes an airway seal 22. The airway seal 22 is fixedly and sealingly connected to the atomization chamber 21. The housing assembly 10 is formed with a mouthpiece 111, and the airway seal 22 communicates with the mouthpiece 111 to form a suction airway 220.

[0116] In this way, by fixedly and sealingly connecting the airway seal 22 and the atomization chamber 21, the parts of the atomization assembly 20 are connected into one body, which is convenient for replacement, and ensures that the aerosol in the suction airway 220 is not easily leaked and is not easily polluted by the external environment.

[0117] Specifically, the airway seal 22 can be a block structure made of rubber, plastic, silica gel and other materials. A pipeline is formed inside the airway seal 22 to communicate the inside of the atomization chamber 21 and the mouthpiece 111 to form a suction airway 220.

[0118] In some examples, the atomization assembly 20 includes an atomization chamber 21, an intake pipe 23 and an airway seal 22. One end of the intake pipe 23 is inserted into the airway seal 22, and the other end extends into the atomization chamber 21. The atomization chamber 21, the intake pipe 23 and the airway seal 22 are connected and encapsulated into a whole and are installed in the first housing 11 together. After the atomization assembly 20 is removed from the first housing 11, the atomization chamber 21 can be separated from the intake pipe 23 and the airway seal 22 to replace, clean the atomization chamber 21 or add atomization medium to the atomization chamber 21.
