Description

Technical Field

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

[0002] In related technologies, aerosol generating devices include a support frame, an airway tube, and an electrical connection interface. Both the airway tube and the electrical connection interface are mounted on the support frame. The support frame has airway holes corresponding to the airway tube and electrical connection holes corresponding to the electrical connection interface. Typically, an airway plug is installed at the airway hole to adjust the suction resistance of the aerosol generating device. A protective plug is installed at the electrical connection hole to prevent damage from external water, dust, or other impurities. However, when the airway hole and the electrical connection hole are located on the same side of the support frame—for example, both at the bottom of the support frame—the airway plug and the protective plug are prone to interference during installation, affecting the normal assembly of the aerosol generating device.

The second connecting portion extends from the first side of the body toward the second side away from the body. In the first state, the second connecting portion extends into the electrical connection interface.

[0006] In some embodiments, a first protrusion is provided between the first connecting portion and the inner wall of the airway tube. In the first state, the first connecting portion is press-fitted with the inner wall of the airway tube through the first protrusion.

[0007] In some embodiments, a second protrusion is provided between the second connecting portion and the inner wall of the electrical connection interface. In the first state, the first connecting portion is interference-fitted with the inner wall of the electrical connection interface through the second protrusion.

[0009] In some embodiments, the body further includes a peripheral side located between the first side and the second side, and the cover is provided with a relief groove that is recessed from the first side of the body toward the second side of the body and communicates with the peripheral side.

[0010] In some embodiments, the bracket has a through hole; the cover includes a main body and a locking portion. The main body is connected to the bracket. The locking portion includes a first end and a second end opposite to each other. The first end of the locking portion is connected to the main body, and the second end of the locking portion passes through the through hole and extends into the bracket. In the first state and the second state, the second end of the locking portion is located inside the bracket.

[0011] In some embodiments, the locking portion is provided with a locking protrusion, which protrudes from the locking portion in a direction away from the central axis of the locking portion, and the locking protrusion is located inside the bracket in the first state and the second state.

[0012] In some embodiments, a third protrusion is provided between the locking part and the inner wall of the through hole, the third protrusion being used to make the locking part and the inner wall of the through hole interference fit.

[0013] In some embodiments, the support includes a support body and a connector connected together, the airway tube and the electrical connection interface are both disposed on the support body, and the main body is disposed on the side of the connector opposite to the support body.

[0014] In some embodiments, the support body has a first hole and the connector has a second hole, the first hole and the second hole together forming the through hole. The support body includes a first sub-frame and a second sub-frame that are combined. The first sub-frame has a first sub-hole and the second sub-frame has a second sub-hole. When the first sub-frame and the second sub-frame are combined, the first sub-hole and the second sub-hole together form the first hole.

[0015] In some embodiments, the bracket is provided with a mounting groove that is recessed from the outside of the bracket toward the center of the bracket.

[0016] In the aerosol generating device of this application embodiment, a cover is connected to a bracket and can switch between a first state and a second state relative to the bracket. The cover has a through hole. When the cover is in the first state, the through hole is connected to the air passage hole, and the cover blocks the electrical connection hole. When the cover is in the second state, the cover opens the air passage hole and the electrical connection hole. In both the first and second states, the air passage pipe is always connected to the outside air. Thus, the cover can simultaneously block the air passage pipe and the electrical connection interface. Compared with the separate air passage plug and protective plug at the air passage hole and electrical connection hole in the related technology, the installation of the cover will not be interfered with, thereby ensuring the normal assembly of the aerosol generating device.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] Please see Figure 1 and Figure 2 The aerosol generating device 100 of this application includes a support 10 and a cover 40. The support 10 is provided with an air passage hole 101 and an electrical connection hole 103. The air passage hole 101 communicates with the air passage tube 20, and the electrical connection hole 103 communicates with the electrical connection interface 30. The cover 40 is connected to the support 10 and can switch between a first state and a second state relative to the support 10. The cover 40 is provided with a through hole 41. When the cover 40 is in the first state, the through hole 41 communicates with the air passage hole 101, and the cover 40 blocks the electrical connection hole 103. When the cover 40 is in the second state, the cover 40 opens the air passage hole 101 and the electrical connection hole 103. In both the first and second states, the air passage tube 20 remains in communication with the outside air.

[0035] Furthermore, please combine Figure 4In some embodiments, the aerosol generating device 100 further includes a power supply unit 50 and a heating component 60, both of which are mounted on the support 10, and the power supply unit 50 is electrically connected to the heating component 60. When the aerosol generating device 100 is being drawn in, the power supply unit 50 supplies power to the heating component 60, causing the heating component 60 to heat the aerosol generating matrix (not shown), thereby generating aerosols from the aerosol generating matrix. It should be noted that the heating component 60 is a structure capable of generating heat energy or transferring heat energy to other parts. In some examples, the heating component 60 can directly convert other forms of energy, such as electrical energy, chemical energy, and solar energy, into heat energy, and conduct it to other parts that need to be heated via heat transfer. In other examples, the heating component 60 can directly act on the surface of the part to be heated, such as electromagnetic waves, lasers, infrared light, or thermal radiation, to raise the temperature of the area receiving the electromagnetic waves, lasers, infrared light, or thermal radiation.

[0036] The support 10 is a structure in the aerosol generating device 100 used to mount the airway tube 20 and the electrical connection interface 30, among other devices. In some embodiments of this application, the airway tube 20 can communicate with the outside air through the airway hole 101, thus ensuring that outside air can enter the airway tube 20 when the aerosol generating device 100 is aspirated to ensure aerosol generation. The electrical connection interface 30 can communicate with the outside air through the electrical connection hole 103, thus ensuring the normal operation of the charging function and / or data transmission function of the aerosol generating device 100. Exemplarily, an external power source can be electrically connected to the charging interface 30 to charge the power supply unit 50. The material of the support 10 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. Exemplarily, the support 10 is made of plastic, which makes the support 10 lighter, thereby contributing to the portability of the aerosol generating device 100.

[0037] The airway tube 20 is a structure in the aerosol generating device 100 used to guide the flow of outside air within the device. In some embodiments, the airway tube 20 and the support 10 are an integral structure, meaning they can be molded as a single unit. This improves the stability of the connection between the airway tube 20 and the support 10, preventing the airway tube 20 from detaching from the support 10 during use and ensuring the normal operation of the aerosol generating device 100. In other embodiments, the airway tube 20 and the support 10 are separate structures, meaning they are two distinct structures. The connection between the airway tube 20 and the support 10 can be detachable or non-detachable. Detachable connections include, but are not limited to, screw connections, snap-fit ​​connections, or a combination of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, adhesive connections, welding, or a combination of adhesive connections and welding connections.

[0038] The electrical connection interface 30 includes, but is not limited to, Type-A, Type-B, and Type-C. In some embodiments of this application, the aerosol generating device 100 further includes a circuit board 70, and both the electrical connection interface 30 and the power supply unit 50 are electrically connected to the circuit board 70. Thus, when the electrical connection interface 30 is electrically connected to an external power source, the electrical energy from the external power source can be transmitted to the power supply unit 50 through the electrical connection interface 30 and the circuit board 70 to charge the power supply unit 50.

[0039] Specifically, in some implementations, the first state (e.g.) Figure 1 (As shown) can be: the state of the cover 40 when it is connected to the airway hole 101 and the electrical connection hole 103, and the cover 40 covers the electrical connection interface 30 and partially blocks the airway hole 101; the second state (as shown) Figure 3 (As shown) can be the state of the cover 40 when the electrical connection hole 103 and the air passage hole 101 are open. It is understood that in some embodiments, the switching of the cover 40 between the first state and the second state requires manual intervention, that is, the cover 40 is manually switched between the first state and the second state; or the cover 40 is manually switched between the first state and the second state with the aid of a tool.

[0040] More specifically, in some embodiments, when the cover 40 is in the first state, it protects the electrical connection interface 30 from damage caused by external water or dust, ensuring the stability and reliability of the aerosol generating device 100. Simultaneously, the cover 40 also adjusts the suction resistance. For example, in the first state, the cover 40 partially covers the air passage 101, increasing the suction resistance of the aerosol generating device 100. In the second state, the cover 40 opens the air passage 101, decreasing the suction resistance. It is understood that in some embodiments, in the second state, the cover 40 opens both the air passage 101 and the electrical connection port 103, allowing the user to clean the air passage 20 and the electrical connection interface 30.

[0041] In the aerosol generating device 100 of this application embodiment, the cover 40 is connected to the bracket 10 and can switch between a first state and a second state relative to the bracket 10. The cover 40 is provided with a through hole 41. When the cover 40 is in the first state, the through hole 41 communicates with the air passage 101, and the cover 40 blocks the electrical connection hole 103. When the cover 40 is in the second state, the cover 40 opens the air passage 101 and the electrical connection hole 103. In both the first and second states, the air passage 20 remains connected to the outside air. Thus, the cover 40 can simultaneously block the air passage 20 and the electrical connection interface 30. Compared with the related technology where air passage plugs and protective plugs are independently set at the air passage and electrical connection holes, the installation of the cover 40 will not be interfered with, thereby ensuring the normal assembly of the aerosol generating device 100.

[0042] The aerosol generating device 100 will be further explained below with reference to the accompanying drawings.

[0043] Please see Figure 1 and Figure 2 In some embodiments, the cross-section of the through hole 41 is smaller than the cross-section of the air passage 101. Thus, even when the cover 40 is in its first state, the air passage 101 can still maintain communication with the outside air. This prevents the cover 40 from blocking the air passage 101 and affecting the normal operation of the aerosol generating device 100 while adjusting the suction resistance of the aerosol generating device 100. Furthermore, the smaller cross-section of the through hole 41 reduces the possibility of external water or dust entering the air passage 20, thereby improving the stability and reliability of the aerosol generating device 100. The cross-sectional shape of the through hole 41 may include, but is not limited to, a circle, square, ellipse, or triangle.

[0044] In some embodiments, a partition protrusion 403 is provided in the through hole 41. The partition protrusion 403 is connected to the inner wall of the through hole 41 and can divide the through hole 41 into a first through hole and a second through hole. This can further reduce the possibility of external water or dust and other impurities entering the airway tube 20, thereby improving the stability and reliability of the aerosol generating device 100.

[0045] Please see Figure 4 and Figure 5 In some embodiments, the bracket 10 is provided with a through hole 105. The cover 40 includes a main body 43, a first connecting portion 45, and a second connecting portion 47. The main body 43 is disposed on the bracket 10 and includes a first side 431 and a second side 433 facing away from each other. The first connecting portion 45 protrudes from the first side 431 of the main body toward the second side 433 away from the main body. In a first state, the first connecting portion 45 extends into the inner cavity of the airway tube 20 and surrounds the through hole 41. The second connecting portion 47 protrudes from the first side 431 of the main body toward the second side 433 away from the main body. In a first state, the second connecting portion 47 extends into the electrical connection interface 30.

[0046] Specifically, please combine Figure 2 In some embodiments, when the cover 40 is in the first state, the first connecting portion 45 passes through the airway hole 101 and extends into the inner cavity of the airway tube 20, the through hole 41 communicates with the airway hole 101, and the second connecting portion 47 passes through the electrical connection hole 103 and extends into the electrical connection interface 30 to cover the electrical connection hole 103. When the cover 40 is in the second state, the first connecting portion 45 extends out of the inner cavity of the airway tube 20 and opens the airway hole 101, and the second connecting portion 47 extends out of the electrical connection interface 30 and opens the electrical connection hole 103. The arrangement of the first connecting portion 45 and the second connecting portion 47 can increase the bonding force between the cover 40 and the airway tube 20, and the bonding force between the cover 40 and the electrical connection interface 30, thereby reducing the possibility of the cover 40 falling off the support 10 during the use of the aerosol generating device 100, preventing the cover 40 from being lost, and ensuring the normal operation of the aerosol generating device 100.

[0047] Furthermore, please combine Figure 5 In some embodiments, a first protrusion 451 is provided between the first connecting part 45 and the inner wall of the airway tube 20. In the first state, the first connecting part 45 is press-fitted with the inner wall of the airway tube 20 through the first protrusion 451.

[0048] Specifically, in some embodiments, when the first connecting portion 45 extends into the airway tube 20, the first protrusion 451 can undergo elastic deformation, thereby achieving an interference fit between the first connecting portion 45 and the inner wall of the airway tube 20 through the first protrusion 451. The first protrusion 451 enhances the bonding force between the first connecting portion 45 and the airway tube 20, reducing the possibility of the cover 40 detaching from the support 10. Furthermore, it seals the gap between the first connecting portion 45 and the inner wall of the airway tube 20, preventing liquids such as water or condensed aerosol from entering the support 10 through this gap and causing damage to structural components within the support 10 (e.g., the electrical connection interface 30 and the circuit board 70), thus ensuring the normal operation of the aerosol generating device 100.

[0049] In one example, the first protrusion 451 is disposed on the outer peripheral wall of the first connecting portion 45, and the first protrusion 451 extends protruding from the outer peripheral wall of the first connecting portion 45 in a direction away from the center of the first connecting portion 45. In another example, the first protrusion 451 is disposed on the inner wall of the airway tube 20, and the first protrusion 451 extends protruding from the inner wall of the airway tube 20 towards the center of the airway tube 20. In some embodiments of this application, the first protrusion 451 may be an annular protrusion or a dotted protrusion, etc.

[0050] In some embodiments, a second protrusion 471 is provided between the second connecting part 47 and the inner wall of the electrical connection interface 30. In the first state, the second connecting part 47 is interference-fitted with the inner wall of the electrical connection interface 30 through the second protrusion 471.

[0051] Specifically, in some embodiments, when the second connecting portion 47 extends into the electrical connection interface 30, the second protrusion 471 can undergo elastic deformation, thereby achieving an interference fit between the second connecting portion 47 and the inner wall of the electrical connection interface 30 through the second protrusion 471. The second protrusion 471 enhances the bonding force between the second connecting portion 47 and the electrical connection interface 30, reducing the possibility of the cover 40 detaching from the bracket 10. Furthermore, it seals the gap between the second connecting portion 47 and the inner wall of the electrical connection interface 30, preventing liquids such as water or condensed aerosols from entering the electrical connection interface 30 through this gap and causing damage, thus ensuring the normal operation of the charging function of the aerosol generating device 100.

[0052] In one example, the second protrusion 471 is disposed on the outer peripheral wall of the second connecting portion 47, and the second protrusion 471 extends protruding from the outer peripheral wall of the second connecting portion 47 in a direction away from the center of the second connecting portion 47. In another example, the second protrusion 471 is disposed on the inner wall of the electrical connection interface 30, and the second protrusion 471 extends protruding from the inner wall of the electrical connection interface 30 towards the center of the electrical connection interface 30. In some embodiments of this application, the second protrusion 471 may be an annular protrusion or a dotted protrusion, etc.

[0053] Due to the size limitations of the aerosol generating device 100, the design size of the cover 40 cannot be too large. Therefore, if the cover 40 is completely detached from the support 10 when in the second state, the cover 40 is easily lost. Please refer to [link / reference needed]. Figure 4 and Figure 5 In some embodiments of this application, the bracket 10 is provided with a through hole 105. The cover 40 also includes a locking portion 49. The locking portion 49 includes a first end 491 and a second end 493 opposite to each other. The first end 491 of the locking portion 49 is connected to the main body 43, and the second end 493 of the locking portion 49 passes through the through hole 105 and extends into the bracket 10. In the first state and the second state of the cover 40, the second end 493 of the locking portion 49 is located inside the bracket 10.

[0054] Specifically, in some embodiments, when the cover 40 switches between a first state and a second state relative to the bracket 10, the second end 493 of the locking part 49 can move within the bracket 10 and be located within the bracket 10. Thus, the cover 40 is less likely to be lost compared to when the cover 40 is completely detached from the bracket 10 in the second state.

[0055] In some embodiments, the locking part 49 is provided with a locking protrusion 495, which protrudes from the locking part 49 in a direction away from the central axis of the locking part 49. In the first state and the second state, the locking protrusion 495 is located inside the bracket 10.

[0056] Specifically, in some embodiments, the cross-sectional dimension of the locking protrusion 495 is larger than the cross-sectional dimension of the through hole 105. Thus, when the cover 40 is in the first state or the second state, the locking protrusion 495 can never pass through the through hole 105 and detach from the bracket 10, thereby reducing the possibility of the cover 40 being lost.

[0057] In some embodiments, a third protrusion 497 is provided between the locking part 49 and the inner wall of the through hole 105, the third protrusion 497 being used to make the locking part 49 and the inner wall of the through hole 105 interference fit.

[0058] Specifically, in some embodiments, when the third protrusion 497 is located within the through hole 105, the third protrusion 497 can undergo elastic deformation, thereby enabling an interference fit between the locking part 49 and the inner wall of the through hole 105 through the third protrusion 497. The third protrusion 497 enhances the bonding force between the locking part 49 and the bracket 10, reducing the possibility of the cover 40 detaching from the bracket 10. Furthermore, it seals the gap between the locking part 49 and the inner wall of the through hole 105, preventing water or condensed aerosols from entering the bracket 10 through this gap and causing damage to structural components within the bracket 10 (such as the electrical connection interface 30 and the circuit board 70), thus ensuring the normal operation of the aerosol generating device 100.

[0059] In one example, the third protrusion 497 is disposed on the outer peripheral wall of the locking portion 49, and the third protrusion 497 extends protruding from the outer peripheral wall of the locking portion 49 in a direction away from the center of the locking portion 49. In another example, the third protrusion 497 is disposed on the inner wall of the through hole 105, and the third protrusion 497 extends protruding from the inner wall of the through hole 105 towards the center of the through hole 105. In some embodiments of this application, the third protrusion 497 may be an annular protrusion or a dotted protrusion, etc.

[0060] Please see Figure 2 In some embodiments, the support 10 includes a support body 11 and a connector 13 connected together. The airway tube 20 and the electrical connection interface 30 are both disposed on the support body 11, and the main body 43 is disposed on the side of the connector 13 opposite to the support body 11. It is understood that in some embodiments, the airway hole 101, the electrical connection hole 103, and the through hole 105 all penetrate the support body 11 and the connector 13.

[0061] Specifically, in some embodiments, the connection between the support body 11 and the connector 13 can be detachable or non-detachable. Detachable connections include, but are not limited to, screw connections, snap-fit ​​connections, or a combination of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, adhesive connections, welding, or a combination of adhesive connections and welding connections. In this application, the embodiment is described only as an example of a detachable connection between the support body 11 and the connector 13.

[0062] Please continue reading. Figure 2In some embodiments, the bracket body 11 has a first hole 111 and the connector 13 has a second hole 131, the first hole 111 and the second hole 131 together form a through hole 105. The bracket body 11 includes a first sub-frame 15 and a second sub-frame 17 that are combined. The first sub-frame 15 has a first sub-hole 151 and the second sub-frame 17 has a second sub-hole 171. When the first sub-frame 15 and the second sub-frame 17 are combined, the first sub-hole 151 and the second sub-hole 171 together form the first hole 111. It should be noted that in some embodiments, the first sub-frame 15 and the second sub-frame 17 can be combined by a detachable connection method, wherein the detachable connection includes, but is not limited to, screw connection, snap-fit ​​connection, or a combination of screw connection and snap-fit ​​connection.

[0063] Specifically, in some embodiments, in the direction perpendicular to the first end 491 to the second end 493 of the locking portion 49, the support body 11 includes a combined first sub-frame 15 and a second sub-frame 17, such that when the first sub-frame 15 and the second sub-frame 17 are combined, the first sub-frame 15 and the second sub-frame 17 can clamp the locking portion 49. It is understood that in some embodiments, when the first sub-frame 15 and the second sub-frame 17 are combined, the first sub-frame 15 and the second sub-frame 17 can also clamp the airway tube 20 and the electrical connection interface 30.

[0064] In some embodiments, the assembly steps between the cover 40 and the bracket 10 may be as follows: First, the cover 40 is assembled with the connector 13; then, the locking part 49 is placed between the separate first sub-frame 15 and second sub-frame 17; subsequently, the first sub-frame 15 and the second sub-frame 17 are connected to form the bracket body 11; finally, the bracket body 11 and the connector 13 are connected to complete the assembly between the cover 40 and the bracket 10. Wherein, when the first sub-frame 15 and the second sub-frame 17 are connected to form the bracket body 11, the locking protrusion 495 is located within the bracket body 11.

[0065] It should be noted that in some embodiments, the connector 13 includes a first side and a second side facing away from each other, with the first side of the connector opposite to the bracket body 11. When the cover 40 and the connector 13 are assembled together, the main body 43 is located on the second side of the connector, and the first connecting part 45, the second connecting part 47, and the locking part 49 all pass through the connector 13 and extend to the first side of the connector. The cross-section of the air passage hole 101 is larger than the cross-section of the locking protrusion 495, and the portion of the air passage hole 101 located on the connector 13 communicates with the portion of the through hole 105 located on the connector 13 (i.e., the second hole 131). Thus, during the assembly of the cover 40 and the connector 13, the locking protrusion 495 can first extend to the first side of the connector through the air passage hole 101, and then the locking part 49 is moved into the second hole 131.

[0066] It is understood that the assembly steps between the cover 40 and the bracket 10 in the above embodiments are merely illustrative. In other embodiments, the assembly steps between the cover 40 and the bracket 10 may take other forms, which will not be described in detail here.

[0067] Please see Figure 3 In some embodiments, the bracket 10 is provided with a mounting groove 19, which is recessed from the outside of the bracket 10 toward the center of the bracket 10. The mounting groove 19 is connected to the airway tube 20 and the electrical connection interface 30. At least a portion of the cover 40 is disposed in the mounting groove 19.

[0068] Specifically, in some embodiments, the mounting groove 19 is recessed from the second side of the connector toward the first side of the connector. When the cover 40 is in the first state, at least a portion of the cover 40 is disposed in the mounting groove 19. Thus, the mounting groove 19 provides positioning for the installation of the cover 40, thereby improving the assembly efficiency of the cover 40; and it also reduces the space occupied by the cover 40, thereby facilitating the miniaturization of the aerosol generating device 100.

[0069] Please see Figures 3 to 5 In some embodiments, the main body 43 further includes a peripheral side 435 located between the first side 431 and the second side 433, and the cover member 40 is provided with a relief groove 401, which is recessed from the first side 431 of the main body toward the second side 433 of the main body, and the relief groove 401 communicates with the peripheral side 435.

[0070] If the cover 40 is in the first state, and the first side 431 of the main body is completely in contact with the bracket 10, it will be difficult for the user to apply force to the cover 40 to change it from the first state to the second state, which will affect the normal use of the aerosol generating device 100. Therefore, the clearance groove 401 in this embodiment facilitates the user to apply force to the cover 40 to change it from the first state to the second state, thereby improving the user experience.

[0071] If there is no gap 80 between the peripheral side 435 and the side wall of the mounting groove 19, it will be difficult for the user to apply force to the cover 40 to change it from the first state to the second state when the cover 40 needs to be changed from the first state to the second state, which will affect the normal use of the aerosol generating device 100. Therefore, in some embodiments of this application, there is a gap 80 between the peripheral side 435 and the side wall of the mounting groove 19, which makes it easier for the user to apply force to the cover 40 to change it from the first state to the second state, thereby improving the user experience.

[0072] Please see Figure 1 and Figure 2 In some embodiments, the aerosol generating device 100 further includes a housing 90, with a support 10 disposed within the housing 90. The housing 90 may be made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the housing 90 may be made of plastic, which makes it lighter and thus contributes to the portability of the aerosol generating device 100.

[0073] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
