Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Technology

[0002] Aerosol generating devices heat an atomizing medium at high temperatures to generate aerosols for inhalation. However, the heating element in these devices needs to be fixed in place, which can easily lead to heat loss due to the fixing mechanism, resulting in low heat utilization. Summary of the Invention

[0003] In view of the above problems, this application provides an aerosol generating apparatus.

[0004] The aerosol generating device according to the embodiments of this application includes a housing assembly, an atomizing assembly, and a heating assembly. The housing assembly has an installation space. The atomizing assembly is detachably connected to the housing assembly and includes an atomizing chamber for containing an atomizing medium. The heating assembly is disposed in the installation space and is configured to be fitted onto the atomizing chamber and detached from the housing assembly when the atomizing chamber is installed in 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 so that the heating element is pressed tightly against the atomizing chamber.

[0005] In the aerosol generating apparatus of this application, the heating element is fitted onto the atomizing chamber during the assembly of the atomizing chamber and the shell assembly, and can detach from the shell assembly to float without the need for other fixing devices. By applying elastic force to the heating element through a heat-resistant elastic component, a firm connection between the heating element and the atomizing chamber is ensured, while also allowing the heating element to fully adhere to the atomizing chamber. This reduces heat loss caused by heat transfer from the heating element to the outside and improves the heat transfer effect to the atomizing medium, thereby enhancing the atomization effect and effectively improving the heat utilization rate.

[0006] In some embodiments, the housing assembly includes a detachably connected first housing and second housing, and an elastic fitting connecting the first housing and the second housing, the first housing and the second housing being opposite each other along a first direction, and the elastic fitting being configured to have a first state of compressive elastic deformation along the first direction and a second state of deformation recovery.

[0007] Thus, by connecting the first and second housings with elastic fittings, when the first and second housings are assembled, the elastic fittings abut against the first and second housings and undergo compressive elastic deformation, thereby sealing the installation space. Furthermore, when the first and second housings are disassembled, the elastic fittings return to their original shape, thus forming elastic contact between the first and second housings, facilitating the assembly and disassembly of the housing components.

[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, and the elastic fitting in the first state has the heat-resistant elastic element abutting against the second housing; in the second state, the elastic fitting has the heating element detached from the second housing.

[0009] Thus, during the assembly of the first and second housings, the elastic component is initially in the first state, the atomizing chamber moves down and connects with the heating element. Subsequently, the elastic component changes from the first state to the second state, and rebounds in the first direction, pushing the first housing, the atomizing chamber, and the heating element connected to the atomizing chamber away from the second housing along the first direction. The heating element detaches from the second housing and is fixed in position only through the atomizing chamber. Thus, the assembly of the atomizing chamber and the heating element is also completed during the assembly of the atomizing chamber and the housing assembly. The operation is simple, and the heating element is fixed in position through the atomizing chamber, reducing heat transfer to the outside.

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

[0011] Thus, by fixing the elastic assembly to one of the first and second housings and detachably connecting it to the other of the first and second housings, the integration of the parts is improved, which is beneficial to the stability of the elastic assembly under force, thereby ensuring that the elastic assembly deforms and rebounds in a preset shape.

[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 range of movement of the heating component when it comes into contact with 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 synchronicity of the first housing's movement as the elastic fitting deforms and rebounds. The limiting structure restricts the movement range of the heating element, allowing it to connect to the atomizing chamber and detach from the second housing, or vice versa, 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 to each other along a first direction, and the spaced and opposite intervals between the first limiting portion and the second limiting portion form a limiting groove, in which a heat-resistant elastic element is accommodated.

[0015] Thus, by having the first limiting part and the second limiting part spaced apart and opposite each other along the first direction, and by housing the heat-resistant elastic element in the limiting groove formed between the first limiting part and the second limiting part, the heat-resistant elastic element moves up and down along the first direction in the limiting groove, thereby limiting the positions of the heat-resistant elastic element and the heating element in the first direction to the first position state, the second position state and the third position state, respectively.

[0016] In some embodiments, the heating element has a first position state in which the elastic fitting is in a first state and the first limiting portion abuts against the heat-resistant elastic member upward in a first direction to make the heating element adhere to the atomizing chamber; and / or, the heating element has a second position state in which the elastic fitting is in a second state and the heat-resistant elastic member is connected to the atomizing chamber and suspended in the limiting groove; and / or, the heating element has a third position state in which the second limiting portion can abut against the heat-resistant elastic member downward in the first direction to separate the heating element from the atomizing chamber.

[0017] Thus, when the heating element is in the first position, the first limiting part abuts against the heat-resistant elastic element upwards until the heating element is in close contact with the atomizing chamber, thereby ensuring that the heat-resistant elastic element is properly positioned on the atomizing chamber, and that the fit between the heating element and the atomizing chamber is neither too tight nor too loose. After the heating element is in close contact with the atomizing chamber, the first limiting part abuts against the heat-resistant elastic element upwards, causing the heating element and the atomizing chamber to move upwards along the first direction. This relaxes the pressure of the first housing on the elastic component, allowing the elastic component to spring back and transition from the first state to the second state.

[0018] The elastic component changes from the first state to the second state, and the heating element moves from the first position state to the second position state, so that the heating element remains in contact with the atomizing chamber and is detached from the second shell. The heat-resistant elastic component is connected to the atomizing chamber and suspended in the limiting groove, thereby reducing heat transfer to components outside the atomizing chamber and improving heat utilization.

[0019] When the heating element moves upward to the third position, it abuts against the heat-resistant elastic element downward through the second limiting part, pushing the heating element and the heat-resistant elastic element out of the atomizing chamber, thereby simplifying the disassembly and replacement of the atomizing chamber.

[0020] In some embodiments, the limiting structure is a limiting plate mounted on the second housing, the limiting plate forming a receiving hole communicating with the limiting groove, the first limiting part and the second limiting part surrounding the receiving hole, and at least a portion of the heating element and the atomizing chamber being accommodated in the receiving hole.

[0021] Thus, the heating element and at least part of the atomizing chamber are accommodated through the receiving hole, and the first limiting part and the second limiting part surround the receiving hole, thereby effectively utilizing the space of the receiving plate and ensuring that the heating component can be limited at all positions in the circumferential direction.

[0022] In some embodiments, the heat-resistant elastic element is an open ring and is housed in a limiting groove. When the heating assembly is in the first position, the heat-resistant elastic element undergoes circumferential elastic deformation and is fitted onto the atomizing chamber so that the heating element is in close contact with the atomizing chamber. When the heating assembly is in the second position, the heating element is in close contact with the atomizing chamber and is suspended in the receiving hole.

[0023] In this way, by making the heat-resistant elastic element an open ring and deforming at the opening, the size of the opening can be expanded when the atomizing chamber is close to the heat-resistant elastic element. Thus, the heat-resistant elastic element can be fitted onto the atomizing chamber and apply elastic force to the atomizing chamber, ensuring that the heating element is stably connected to the atomizing chamber and moves synchronously. As a result, the heating element can remain close to the atomizing chamber and float in the receiving hole, reducing heat transfer to components outside the atomizing chamber and improving heat utilization.

[0024] In some embodiments, the heat-resistant elastic element has several notches formed on the side facing the atomizing chamber radially.

[0025] In this way, by forming several notches in the heat-resistant elastic component radially toward the atomizing chamber, the contact area between the heat-resistant elastic component and the atomizing chamber is reduced, thereby reducing heat loss on the heat-resistant elastic component.

[0026] In some embodiments, the heating element includes a main body and a connecting part. The main body has a hollow disc-shaped structure and is housed in a receiving hole. The main body is connected to a plurality of connecting parts, which are arranged at intervals along the circumference of the main body. The connecting parts extend upward from the main body along a first direction to a heat-resistant elastic element.

[0027] In this way, the main body forms a hollow disc shape, which increases the resistance heating power, and the heat-resistant elastic element is connected by multiple spaced connecting parts, which reduces the heat transfer from the main body to the heat-resistant elastic element.

[0028] In some embodiments, the surface of the atomizing chamber that abuts against the heat-resistant elastic element forms an angle with the first direction.

[0029] Thus, by forming an angle between the surface of the atomizing chamber and the heat-resistant elastic component that abuts against the first direction, the atomizing chamber can circumferentially compress the heat-resistant elastic component and deform it during its movement along the first direction, thereby ensuring the smooth assembly and disassembly of the atomizing chamber.

[0030] In some embodiments, the atomizing assembly further includes an airway seal, which is fixed and sealed to the atomizing chamber, and the housing assembly forms a mouthpiece, with the airway seal connecting to the mouthpiece to form a suction airway.

[0031] In this way, the airway seal is fixed and sealed to the atomizing chamber, so that all parts of the atomizing component are connected as one unit, which is convenient for replacement and ensures that the aerosol in the suction airway is not easily leaked or contaminated by the external environment.

[0049] The aerosol generating device 100 is a structure capable of generating aerosols from an atomizing medium by at least one of the following methods: resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasonication, or mechanical vibration. The atomizing medium is a substance that has been treated and heated to produce aerosols. The atomizing medium is heated and atomized to form aerosols, which can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol may contain volatile compounds. Users can inhale the aerosols into their mouth, nasal cavity, or lungs through their mouth or nose. The aerosols inhaled into the user's respiratory system can be used for various purposes such as food, medicine, health care, and entertainment.

[0050] The atomizing medium can be in a completely solid or semi-solid state, or it can be liquid. For example, a solid atomizing medium can be a plant flower, stem, or leaf product prepared by processes such as rolling, slurry preparation, die casting, or extrusion. As another example, a liquid atomizing medium can include liquid compositions based on plant extracts and / or various fragrances.

[0051] Please see Figures 1-4 The aerosol generating device 100 of this application includes a housing assembly 10, an atomizing assembly 20, and a heating assembly 30. The housing assembly 10 forms an installation space 101. The atomizing assembly 20 is detachably connected to the housing assembly 10 and includes an atomizing chamber 21 for containing the atomizing medium. The heating assembly 30 is disposed in the installation space 101 and is configured to be sleeved on the atomizing chamber 21 and detached from the housing assembly 10 when the atomizing 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 so that the heating element 32 is pressed tightly against the atomizing chamber 21.

[0052] In the aerosol generating apparatus 100 of this application embodiment, the heating element 30 is fitted onto the atomizing chamber 21 during the assembly of the atomizing chamber 21 and the housing assembly 10, and can detach from the housing assembly 10 to float without the need for other fixing devices. The heat-resistant elastic element 31 applies an elastic force to the heating element 32, ensuring a firm connection between the heating element 30 and the atomizing chamber 21 while allowing the heating element 32 to fully adhere to the atomizing chamber 21. This reduces heat loss caused by heat transfer from the heating element 30 to the outside and improves the heat transfer effect to the atomizing medium, thereby enhancing the atomization effect and effectively improving the heat utilization rate.

[0053] Specifically, the atomizing chamber 21 can be a hollow cylinder, and it can be cylindrical, conical, capsule-shaped, or other composite structures. The cross-sectional and longitudinal shapes of the atomizing chamber 21 can be circular, elliptical, triangular, square, rhomboid, polygonal, star-shaped, racetrack-shaped, or other irregular shapes; this application does not impose any limitations on these shapes. This application uses a cylindrical atomizing chamber 21 provided in some embodiments as an example. As shown in Figure X, the atomizing chamber 21 has an open end 210 along its axial direction and a closed bottom at the other end. In this embodiment, the atomizing medium can be a semi-solid substance such as a paste or gruel, and is coated on the inner surface of the bottom of the atomizing chamber 21.

[0054] The heating element 32 is a component capable of generating heat through at least one of the following methods: resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasonic or mechanical vibration. For example, the heating element 32 heats based on the principle of resistance heating, and the heating element 32 is conductive and capable of converting electrical energy into heat energy when energized.

[0055] The heat-resistant elastic element 31 is fixedly connected to the heating element 32 by at least one of the following methods: snap-fit ​​connection, welding, riveting, screwing, gluing connection, or fastener connection. For example, the heat-resistant elastic element 31 is snap-fit ​​connected to the heating element 32.

[0056] Please continue reading. Figures 1-4 In some embodiments, the housing assembly 10 includes a detachably connected first housing 11 and second housing 12 and an elastic fitting 13 connecting the first housing 11 and the second housing 12, the first housing 11 and the second housing 12 being opposite each other along a first direction, and the elastic fitting 13 being configured to have a first state of compressive elastic deformation along the first direction and a second state of deformation recovery.

[0057] Thus, the first housing 11 and the second housing 12 are connected by 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 undergoes compressive elastic deformation, thereby sealing the installation space 101. Furthermore, when the first housing 11 and the second housing 12 are disassembled, the elastic fitting 13 deforms and returns to its original shape, thereby forming elastic contact between the first housing 11 and the second housing 12, facilitating the assembly and disassembly 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 are opposite to and connected along a first direction. The hollow sections inside the first housing 11 and the second housing 12 can communicate with each other to form an installation space 101. For ease of explanation, in the following description, the direction along the first direction from the first housing 11 to the second housing 12 is defined as the top-to-bottom direction. The atomizing chamber 21 is arranged in the installation space 101 with its own axis parallel to the first direction, and the end of the atomizing chamber 21 with the opening 210 is located at the top. In other examples, the atomizing chamber 21 may also be arranged at an angle to the first direction.

[0059] The first housing 11 and the second housing 12 can be connected by at least one of the following methods: snap-fit ​​connection, threaded connection, fastener connection, adhesive connection, etc. For example, the first housing 11 and the second housing 12 are snap-fit ​​connected, with the lower end of the first housing 11 and the upper end of the second housing 12 engaging. 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 this application embodiment does not impose any special limitations on this.

[0060] A resilient fitting 13 is disposed between the first housing 11 and the second housing 12. The upper side of the resilient fitting 13 is connected to the first housing 11, and the lower side is connected to the second housing 12. When the housing assembly 10 begins to assemble, the first housing 11 and the second housing 12 move closer to each other along a first direction, pressing the resilient fitting 13 from the upper and lower sides respectively. The resilient fitting 13 is compressed in the first direction, causing it to be in a position such that… Figure 6 The first state is shown. When the first housing 11 and the second housing 12 are fully assembled, the elastic fitting 13 springs back and transitions from the first state to the state shown. Figure 3 The second state is shown. It should be noted that in the second state, the first housing 11 and the second housing 12 remain connected, and the elastic assembly 13 is still subjected to the compressive force applied by the first housing 11 and the second housing 12, and has a certain degree of compression deformation, but the degree of compression 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 along the first direction until they are completely separated, and the elastic fitting 13 returns to its original deformation as follows. Figure 7 The natural state is shown. It can be understood that the width of the elastic fitting 13 in the first direction increases sequentially from the first state, the second state to the natural state.

[0062] Please see Figures 2-4 In some embodiments, the atomizing component 20 is connected to the first housing 11, the heating component 30 is disposed on the second housing 12 and is opposite to the atomizing chamber 21 in a first direction, and the elastic fitting 13 in the first state has the heat-resistant elastic element 31 abutting against the second housing 12; in the second state, the elastic fitting 13 has the heating element 32 detached from the second housing 12.

[0063] Thus, during the assembly of the first housing 11 and the second housing 12, the elastic fitting 13 is initially in the first state, the atomizing chamber 21 moves down and connects with the heating element 30, and then the elastic fitting 13 changes from the first state to the second state. The elastic fitting 13 rebounds in the first direction, pushing the first housing 11, the atomizing chamber 21, and the heating element 30 connected to the atomizing chamber 21 away from the second housing 12 in the first direction. The heating element 30 is detached from the second housing 12 and is fixed in position only through the atomizing chamber 21. Thus, the assembly of the atomizing chamber 21 and the heating element 30 is also completed during the assembly of the atomizing chamber 21 and the housing assembly 10. The operation is simple, and the heating element 30 is fixed in position only through the atomizing chamber 21, reducing heat transfer to the outside.

[0064] Specifically, the first housing 11 and the atomizing component 20 can be connected as a whole by a silicone elastic seal to form an airtight airflow channel. The heating component 30 is movable relative to the second housing 12.

[0065] During the assembly of the first housing 11, the atomizing component 20, and the second housing 12, the atomizing chamber 21 is first fixedly installed inside the first housing 11 by an elastic seal, and the heating component 30 is installed on the second housing 12; the first housing 11 and the atomizing component 20 move downward along the first direction towards the second housing 12, and the elastic fitting 13 is compressed and deformed in the first direction, from which... Figure 7 The natural state shown gradually moves towards... Figure 6 The first state transition shown in the diagram involves the atomizing component 20 moving with the first housing 11 and approaching the heating component 30, allowing the atomizing chamber 21 to be directly opposite the heating component 30 along the first direction. When the elastic fitting 13 reaches the first state, the first housing 11 and the second housing 12 are engaged, the heating component 30 is fitted onto the atomizing chamber 21, and the heating element 32 is pressed against the bottom of the atomizing chamber 21. At this time, the heating component 30 and the atomizing chamber 21 are connected together and can move as a whole. Subsequently, the elastic fitting 13 returns to its original shape, transitioning from the first state to the state shown in the diagram. Figure 3 In the second state shown, in this step, the elastic fitting 13 provides a rebound force to push the first housing 11, the atomizing component 20 and the heating component 30 upward as a whole, the heating component 30 disengages from the second housing 12, and the first housing 11 and the second housing 12 remain engaged.

[0066] It is understandable that the elastic assembly 13 rebounds a distance less during the transition from the first state to the second state than it contracts during the transition 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 do not separate during the rebound.

[0067] In some embodiments, the resilient 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] Thus, by fixing 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 integration of the parts is improved, which is beneficial to the stability of the elastic fitting 13 under force, thereby ensuring that the elastic fitting 13 deforms and rebounds in a preset shape.

[0069] For example, the elastic fitting 13 is a rubber ring, which can be pre-fitted onto the base 121 and reinforced by adhesive or the like.

[0070] For example, the elastic fitting 13 is a rubber ring, which is fixedly connected to the first housing 11 to form a whole and can be moved as a whole until it is installed on the second housing 12.

[0071] In the above embodiment, when the first housing 11 and the second housing 12 are engaged, the first housing 11 presses the rubber ring downwards, and the second housing 12 presses the rubber ring upwards.

[0072] Please see 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 atomizing component 20 and the heating component 30 are all disposed 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 component 30 when it abuts against the atomizing chamber 21.

[0073] Thus, 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 springs back when the first housing 11 is installed on the base 121, improving the synchronicity of the movement of the first housing 11 as it deforms and springs back. The limiting structure 122 restricts the movement range of the heating element 30, allowing the heating element 30 to connect with the atomizing chamber 21 and detach from the second housing 12, or vice versa, within a preset movement range.

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

[0075] A limiting structure 122 is mounted at the mounting opening 1211 of the base 121. The limiting structure 122 can be fixedly connected to the base 121 by at least one of the following methods: welding, threaded connection, riveting, snap-fit ​​connection, adhesive connection, or fastener connection. For example, the base 121 has a snap-fit ​​groove 1213 formed on its inner wall surface at the mounting opening 1211, and the limiting structure 122 has a protruding rib 1226. The limiting structure 122 is fixedly installed inside the base 121 by snap-fitting the protruding rib 1226 into the snap-fit ​​groove 1213. When the heating element 30 and the atomizing element 20 are separated, the heating element 30 abuts against the limiting structure 122 and is placed at the mounting opening 1211 of the base 121 through the limiting structure 122.

[0076] Please see 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 along a first direction. The spaced and opposite intervals of the first limiting portion 1221 and the second limiting portion 1222 form a limiting groove 1223, and the heat-resistant elastic member 31 is accommodated in the limiting groove 1223.

[0077] Thus, by having the first limiting part 1221 and the second limiting part 1222 spaced apart and opposite each other along the first direction, and by housing the heat-resistant elastic member 31 in the limiting groove 1223 formed between the first limiting part 1221 and the second limiting part 1222, the heat-resistant elastic member 31 moves up and down along the first direction in the limiting groove 1223, thereby the first limiting part 1221, the limiting groove 1223 and the second limiting part 1222 together restrict the position range of the heat-resistant elastic member 31 and the heating element 32 along the first direction.

[0078] Specifically, the first limiting part 1221 is disposed below the second limiting part 1222, and the heat-resistant elastic member 31 is disposed in the limiting groove 1223. The first limiting part 1221 limits the lower limit position of the heat-resistant elastic member 31 in the limiting groove 1223, and the second limiting part 1222 limits the upper limit position of the heat-resistant elastic member 31 in the limiting groove 1223. The first limiting part 1221 and the second limiting part 1222 can be one of the following structures: protrusion, flange, locking block, rod, sleeve, plane or inclined surface, etc., and this application does not limit them.

[0079] Please see Figure 3 , Figure 6 and Figure 7 In some embodiments, the heating element 30 has a first position state in which the elastic fitting 13 is in a first state and the first limiting portion 1221 abuts against the heat-resistant elastic member 31 upward in a first direction to make the heating element 32 adhere to the atomizing chamber 21; and / or, the heating element 30 has a second position state in which the elastic fitting 13 is in a second state and the heat-resistant elastic member 31 is connected to the atomizing chamber 21 and suspended in the limiting groove; and / or, the heating element 30 has a third position state in which the second limiting portion 1222 can abut against the heat-resistant elastic member 31 downward in a first direction to separate the heating element 32 from the atomizing chamber 21.

[0080] That is, the heating component 30 sequentially has a first position state along the first direction (e.g. Figure 6 As shown), the second position state (as shown) Figure 3 (as shown) and the third position state (as shown) Figure 7 (As shown).

[0081] Before and after assembling and disassembling the atomizing component 20 and the heating component 30, the heat-resistant elastic member 31 can abut against the first limiting part 1221 to restrict the heating component 30 as follows: Figure 6 The first position state is shown. During the assembly of the atomizing component 20 and the heating component 30, the heat-resistant elastic member 31 is supported by the first limiting part 1221 in the first position state, pressing against the outer wall of the atomizing chamber 21 and assembling with the atomizing component 20.

[0082] When the atomizing component 20 and the heating component 30 are assembled, the heating component 30 and the atomizing component 20 form a whole, and the heating component 30 moves from... Figure 6 The first position state shown is moved to, as Figure 3 The second position state is shown. When the heating component 30 is in the second position state, the heat-resistant elastic element 31 can be locked together with the atomizing chamber 21 and suspended in the limiting groove 1223.

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

[0084] Thus, when the heating element 30 is in the first position, the first limiting part 1221 abuts against the heat-resistant elastic member 31 until the heating element 32 is in close contact with the atomizing chamber 21, thereby ensuring that the heat-resistant elastic member 31 is properly positioned on the atomizing chamber 21, and that the heating element 32 is not too tight or too loose in contact with the atomizing chamber 21.

[0085] After the heating element 32 is pressed against the atomizing chamber 21, the first limiting part 1221 abuts against the heat-resistant elastic member upward, so that the heating component 30 and the atomizing chamber 21 have a tendency to move upward in the first direction, thereby the first shell 11 relaxes the pressure on the elastic fitting 13, and the elastic fitting 13 can rebound and change from the first state to the second state.

[0086] Specifically, during the assembly of the atomizing component 20 with the first housing 11 and the second housing 12, the atomizing component 20 moves downward with the first housing 11, and the bottom of the atomizing chamber 21 gradually approaches and contacts the heating component 30. The downward pressure of the first housing 11 and the upward support force of the first limiting part 1221 jointly push the heat-resistant elastic member 31 to engage with the atomizing chamber 21, causing the heating element 32 to adhere to the outer surface of the bottom of the atomizing chamber 21. Subsequently, the first housing 11 is relieved of external force, and the elastic component 13 releases stress during the recovery deformation process from the first state to the second state, pushing the first housing 11, the atomizing chamber 21, and the heating component 30 attached to the bottom of the atomizing chamber 21 upward, and the heat-resistant elastic member 31 separates from the first limiting part 1221.

[0087] Please see 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 element 31 is connected to the atomizing chamber 21 and suspended in the limiting groove.

[0088] Thus, 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 atomizing chamber 21 and is detached from the second housing 12. The heat-resistant elastic component 31 is connected to the atomizing chamber 21 and suspended in the limiting groove 1223, thereby reducing heat transfer to components outside the atomizing chamber 21 and improving heat utilization.

[0089] Specifically, the aerosol generating device 100 uses the heating component 30 to heat the atomizing medium in the atomizing chamber 21 to generate aerosol for the user to inhale, while the heating component 30 remains in the second position.

[0090] Please see Figure 7 In some embodiments, when the heating element is in the third position, the second limiting part 1222 abuts against the heat-resistant elastic member 31 downward along the first direction to separate the heating element 32 from the atomizing chamber 21.

[0091] Thus, when the atomizing chamber 21 moves the heating element 30 upward to the third position, the second limiting part 1222 abuts against the heat-resistant elastic member 31 downward, pushing the heating element 32 and the heat-resistant elastic member 31 out of the atomizing chamber 21, thereby simplifying the disassembly and replacement of the atomizing chamber 21.

[0092] Specifically, during the separation of the atomizing component 20 from the first housing 11 and the second housing 12, the atomizing component 20 moves upward with the first housing 11, and the heat-resistant elastic member 31 gradually moves to the third position and abuts against the second limiting part 1222. The atomizing chamber 21 is pulled upward by the first housing 11, and the heat-resistant elastic member 31 is supported downward by the second limiting part 1222. Together, they push the atomizing chamber 21 and the heat-resistant elastic member 31 to separate, and the heating element 32 also detaches from the surface of the atomizing chamber 21. During the above process, the elastic fitting 13 changes from the second state to the natural state.

[0093] In scenarios such as when the atomizing chamber 21 reaches the end of its service life, when the user needs to use different types of atomizing media, or when the atomizing media is insufficient and needs to be replenished, the atomizing chamber 21 can move with the first housing 11 and detach from the heating element 30 during the separation of the first housing 11 and the second housing 12. After installing a new atomizing chamber 21 on the first housing 11, the assembly steps are repeated to complete the replacement of the atomizing chamber 21, which is simple to operate.

[0094] Please see Figures 4-7 In some embodiments, the limiting structure 122 is a limiting plate 1224 mounted on the second housing 12. The limiting plate 1224 forms a receiving hole 1225 that communicates with the limiting groove 1223. The first limiting part 1221 and the second limiting part 1222 surround the receiving hole 1225. At least a portion of the heating element 32 and the atomizing chamber 21 are accommodated in the receiving hole 1225.

[0095] Thus, the heating element 32 and at least a portion of the atomizing chamber 21 are accommodated through the receiving hole 1225, and the first limiting part 1221 and the second limiting part 1222 surround the receiving hole 1225, thereby effectively utilizing the space of the receiving plate and ensuring that the heating component 30 is limited at all positions in the circumferential direction.

[0096] Specifically, the receiving hole 1225 can be a through hole that penetrates the upper and lower surfaces of the limiting plate 1224, and the heating element 32 can partially pass through the receiving hole 1225 and extend to 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, referring to... Figure 4 The cross-sectional shape of both the limiting plate 1224 and the base 121 is racetrack-shaped. A ring of raised ribs 1226 is formed on the outer peripheral surface of the limiting plate 1224. The raised ribs 1226 engage with the engaging grooves 1213 on the inner wall of the second housing 12, thus mounting the limiting plate 1224 at the mounting opening 1211.

[0098] The receiving hole 1225 communicates with the limiting groove 1223. The limiting groove 1223 can be formed by recessing from the peripheral wall of the receiving hole 1225. The first limiting part 1221 and the second limiting part 1222 surround the receiving hole 1225 on the upper and lower surfaces of the limiting plate 1224, respectively. The limiting groove 1223 is formed inside the receiving plate. When the thickness of the first limiting part 1221 and the second limiting part 1222 is the same, the limiting groove 1223 surrounds the receiving hole 1225 at the middle position between the upper and lower surfaces of the limiting plate 1224.

[0099] In other examples, the receiving hole 1225 may also be a blind hole and opened on the upper surface of the limiting plate 1224, with the bottom of the receiving hole 1225 closed or semi-closed and serving as the first limiting part 1221.

[0100] Please see Figures 4-8 In some embodiments, the heat-resistant elastic element 31 is an open annular shape and is accommodated in the limiting groove 1223. When the heating component 30 is in the first position state, the heat-resistant elastic element 31 undergoes circumferential elastic deformation and is sleeved on the atomizing chamber 21 so that the heating element 32 is close to the atomizing chamber 21. When the heating component 30 is in the second position state, the heating element 32 is close to the atomizing chamber 21 and is suspended in the receiving hole 1225.

[0101] Thus, by making the heat-resistant elastic element 31 an open ring and deforming at the opening 311, the size of the opening 311 can be expanded when the atomizing chamber 21 is close to the heat-resistant elastic element 31. This allows the heat-resistant elastic element 31 to be fitted onto the atomizing chamber 21 and apply elastic force to the atomizing chamber 21, ensuring that the heating element 30 is stably connected to the atomizing chamber 21 and moves synchronously. This allows the heating element 32 to remain close to the atomizing chamber 21 and float in the receiving hole 1225, reducing heat transfer to components other than the atomizing chamber 21 and improving heat utilization.

[0102] Specifically, the heat-resistant elastic element 31 can be coaxial with the atomizing chamber 21, with the bottom of the atomizing chamber 21 extending into the center of the heat-resistant elastic element 31. The heat-resistant elastic element 31 can be a ring clamp forming an opening 311 to hold the bottom of the atomizing chamber 21. The inner diameter of the heat-resistant elastic element 31 is slightly smaller than the outer diameter of the atomizing chamber 21 when no external force is applied. When the heating element 30 is in the first position, it is subjected to the force of the first limiting part 1221 and the atomizing chamber 21, causing the heat-resistant elastic element 31 to undergo circumferential elastic deformation, the opening 311 to expand, and the circumference of the heat-resistant elastic element 31 to increase, allowing it to be fitted onto the atomizing chamber 21. The heat-resistant elastic element 31 applies a centripetal elastic force to the atomizing chamber 21, causing the heat-resistant elastic element 31 and the heating element 32 to press against the outer wall of the atomizing chamber 21.

[0103] like Figure 3 As shown, when the heating component 30 is in the second position state, the heat-resistant elastic member 31 clamps the atomizing chamber 21 and suspends it in the limiting groove 1223, and the heating element 32 is attached to the atomizing chamber 21 and suspended in the receiving hole 1225. The part of the heat-resistant elastic member 31 connected to the heating element 32 can be partially suspended in the limiting groove 1223 or the receiving hole 1225.

[0104] like Figure 7 As shown, when the heating component 30 is in the third position, the second limiting part 1222 abuts against the heat-resistant elastic member 31 downwards, the heat-resistant elastic member 31 slides off from the bottom of the atomizing chamber 21 and returns to its original deformation, the opening 311 shrinks, and the heat-resistant elastic member 31 drives the heating element 32 to detach from the atomizing chamber 21.

[0105] Please see Figure 5 and Figure 8 In some embodiments, the heat-resistant elastic element 31 has several notches 312 formed on the side radially toward the atomizing chamber 21.

[0106] Thus, by forming several notches 312 on the side of the heat-resistant elastic element 31 facing the atomizing chamber 21 in the radial direction, the contact area between the heat-resistant elastic element 31 and the atomizing chamber 21 is reduced, thereby reducing the heat loss on the heat-resistant elastic element 31.

[0107] Specifically, when the heat-resistant elastic element 31 is fitted onto the atomizing chamber 21, the inner circumference of the heat-resistant elastic element 31 faces the atomizing chamber 21 and is partially pressed against it. The inner diameter of the heat-resistant elastic element 31 at the notch 312 is larger than the outer diameter of the atomizing chamber 21, and the heat-resistant elastic element 31 at the notch 312 does not contact the atomizing chamber 21. The notch 312 can extend along the circumference of the heat-resistant elastic element 31 into an arc-shaped block, or it can be in various shapes such as fan-shaped, square, semi-circular, or semi-elliptical.

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

[0109] Thus, the hollowed-out disc shape formed by the main body 321 increases the resistance heating power, and the heat-resistant elastic element 31 is connected by multiple spaced connecting parts 322, reducing the heat transfer from the main body 321 to the heat-resistant elastic element 31.

[0110] Specifically, the heating element 30 is mounted on the atomizing chamber 21, with the main body 321 closely attached to the bottom of the atomizing chamber 21, and the connecting part 322 opposite to the bottom of the atomizing chamber 21 but not in contact with the wall of the atomizing chamber 21. The main body 321 is a thin sheet or plate structure, and its shape matches the cross-sectional shape of the atomizing chamber 21. For example, the main body 321 is shaped like... Figure 8 The circular shape is shown. The main body 321 has several perforations or through holes to increase the resistance of the main body 321 when the heating element 32 is connected to electricity, thereby increasing the heating power. The connecting part 322 can be strip-shaped, extending from bottom to top and passing through the notch 312 into the heat-resistant elastic member 31. The end of the extending connecting part 322 can be hook-shaped and engage with the heat-resistant elastic member 31. Four connecting parts 322 can be provided on the circular main body 321, arranged radially opposite each other, to improve structural stability.

[0111] Please see Figure 6 and Figure 7 The heat-resistant elastic member 31 and the main body 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 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 321 can extend out of the receiving hole 1225 and be lower than the lower surface of the limiting plate 1224.

[0112] Please see Figure 3 In some embodiments, the surfaces of the atomizing chamber 21 that abut against the heat-resistant elastic member 31 form an angle with the first direction.

[0113] Thus, by forming an angle between the surface of the atomizing chamber 21 and the heat-resistant elastic component 31 and the first direction, the atomizing chamber 21 can circumferentially compress the heat-resistant elastic component 31 and deform it during the movement along the first direction, thereby ensuring that the atomizing chamber 21 can be easily disassembled and assembled.

[0114] Specifically, the outer surface of the bottom of the atomizing chamber 21 can be an arc surface, or the connection between the bottom of the atomizing chamber 21 and the side wall of the atomizing chamber 21 has rounded corners. It is easy to understand that the heat-resistant elastic member 31 is subjected to a supporting force or thrust from the first limiting part 1221 and the second limiting part 1222 in the first direction, and is subjected to a force perpendicular to the direction of the surface in contact with the atomizing chamber 21, thereby producing elastic deformation. To cause the heat-resistant elastic member 31 to expand or contract circumferentially at the opening 311, the surface of the atomizing chamber 21 abutting against the heat-resistant elastic member 31 forms an angle with the first direction, thereby generating a component force along the circumferential or radial direction of the heat-resistant elastic member 31, which pushes the heat-resistant elastic member 31 to deform as the atomizing chamber 21 approaches and fits into the heat-resistant elastic member 31 from top to bottom.

[0115] Please see 2- Figure 4 In some embodiments, the atomizing assembly 20 further includes an airway seal 22, which is fixed and sealed to the atomizing chamber 21. The housing assembly 10 has a mouthpiece 111, and the airway seal 22 connects to the mouthpiece 111 to form a suction airway 220.

[0116] In this way, the airway seal 22 is fixed and sealed to the atomizing chamber 21, so that all parts of the atomizing component 20 are connected as one unit, which is convenient for replacement and ensures that the aerosol in the suction airway 220 is not easily leaked or contaminated by the external environment.

[0117] Specifically, the airway seal 22 can be a block structure made of materials such as rubber, plastic, or silicone. The airway seal 22 has a channel inside to connect the inside of the atomizing chamber 21 and the mouthpiece 111 to form a suction airway 220.

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