[0039] See also Figure 1 and Figure 2 The heating assembly 100 of the embodiment of the present application is used in an aerosol generating device 1000 ( Figure 4). The heating assembly 100 includes a bracket 10, a heating module 40, a first cover body 20 and a second cover body 30. The bracket 10 includes a first end 11 and a second end 13 opposite to each other, and the bracket 10 includes a receiving cavity 101. The heating module 40 is disposed in the receiving cavity 101. The first cover body 20 and the second cover body 30 are respectively mounted at opposite ends of the heating module 40 along the axial direction X. Among them, the bracket 10 can be sleeved with the first cover body 20 and the heating module 40 from one end of the first cover body 20 along the axial direction X, the first end 11 of the bracket 10 is connected to the first cover body 20, and the second end 13 of the bracket 10 is connected to the second cover body 30.

[0040] In some embodiments, the first cover 20 and the bracket 10, and the second cover 30 and the bracket 10 can be connected by a detachable connection method such as a snap connection or a threaded connection, thereby facilitating the installation and removal of the first cover 20 and the bracket 10, and the second cover 30 and the bracket 10, thereby ensuring the normal operation of the heating component 100. It should be noted that in some embodiments, the bracket 10, the first cover 20 and the second cover 30 can be made of one or more materials such as ceramics, polyetheretherketone (PEEK), silicon dioxide, mica, copper oxide or manganese dioxide.

[0041] The heating module 40 is a structure that can generate heat energy or transfer heat energy to other parts. For example, the heating module 40 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 through heat transfer; for another example, the heating module 40 emits other forms of energy such as electromagnetic waves, lasers, infrared light or thermal radiation that can directly act on the surface of the part to be heated, so that the temperature of the area receiving the electromagnetic waves, lasers, infrared light or thermal radiation increases. In the present application, the heating module 40 may include a heating element, which can generate heat and transfer heat to the aerosol generating substrate (not shown) contained in the accommodating cavity 101, so that the aerosol generating substrate is heated to generate aerosol for the user to inhale. It should be noted that in some embodiments, the heating element is a hollow cylindrical structure. When the aerosol generating substrate is contained in the accommodating cavity 101, the aerosol generating substrate is at least partially located in the heating element, that is, the heating element is sleeved on the aerosol generating substrate, thereby, the heating element can heat and atomize the aerosol generating substrate.

[0042] Among them, the aerosol generating substrate is an element that can generate aerosols. Specifically, the aerosol generating substrate can be made into fine particles by heating or ultrasonic vibration, and mixed with air to form an aerosol. The form of the aerosol generating substrate can be solid or liquid, wherein the aerosol generating substrate can be sheet-shaped or columnar, etc. In the present application, the aerosol generating substrate is cylindrical. The aerosol can be visible or invisible and can include steam (for example, fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed steam. The "aerosol" herein covers the aerosol generated when the aerosol generating substrate in the heated aerosol generating device 1000 is heated.

[0043] In the case where the heating element is a hollow cylindrical structure and the aerosol generating substrate is contained in the containing cavity 101, at least part of the aerosol generating substrate is located inside the heating element. In this case, the aerosol generated by the aerosol generating substrate is located inside the heating element and can be inhaled by the user. However, if the aerosol leaks to the outside of the heating element through the gap between the heating module 40 and the first cover 20, or the gap between the heating module 40 and the second cover 30, the aerosol will cause corrosion damage to the circuit structure disposed on the outside of the heating element and / or the internal structure of the aerosol generating device 1000, thereby affecting the normal operation of the heating module 40 and being detrimental to the safe use of the heating assembly 100. In the embodiment of the present application, the heating assembly 100 includes a first seal 50 and a second seal 60. The first seal 50 is disposed between the heating module 40 and the first cover 20 to seal the gap between the heating module 40 and the first cover 20; the second seal 60 is disposed between the heating module 40 and the second cover 30 to seal the gap between the heating module 40 and the second cover 30. Thus, the arrangement of the first seal 50 and the second seal 60 can reduce or even prevent aerosol leakage to the outside of the heating element, thereby ensuring the normal operation of the heating module 40, extending the service life of the heating module 40, and improving the safety of the use of the heating assembly 100. It should be noted that, in some embodiments, the materials of the first seal 50 and the second seal 60 include but are not limited to rubber, plastic or silicone.

[0044] In the heating component 100 of the embodiment of the present application, the first cover body 20 and the second cover body 30 are respectively installed at the opposite ends of the heating module 40 along the axial direction X, and the bracket 10 can be sleeved with the first cover body 20 and the heating module 40 from one end of the first cover body 20 along the axial direction X, and the first end 11 of the bracket 10 is connected to the first cover body 20, and the second end 13 of the bracket 10 is connected to the second cover body 30. Therefore, compared with the cover body (including the first cover body 20 and / or the second cover body 30) and the bracket 10 as an integral structure, the installation process between the opposite ends of the heating module 40 and other structures in this embodiment is visible, thereby preventing the heating module 40 from being blindly installed, resulting in inaccurate installation and positioning, reducing the assembly defect rate of the heating component 100, and thereby ensuring the normal operation of the aerosol generating device 1000.

[0045] The heating assembly 100 is further described below with reference to the accompanying drawings.

[0046] See also Figure 1 and Figure 2 In some embodiments, the first seal 50 is connected to the first cover 20. Specifically, in some embodiments, the first seal 50 can be connected to the first cover 20 in a detachable manner, so that it can be easily removed and replaced when the first seal 50 is damaged (such as wear or aging). The detachable connection method includes but is not limited to a snap-on or threaded connection. In other embodiments, the first seal 50 can be connected to the first cover 20 in a non-detachable manner, thereby improving the bonding strength between the first seal 50 and the first cover 20 to prevent the aerosol generating device 1000 ( Figure 4 As shown in the figure, the first sealing member 50 falls off from the first cover body 20 during use, ensuring the sealing effect of the first sealing member 50 on the gap between the first cover body 20 and the heating module 40. Among them, the non-detachable connection method includes but is not limited to bonding or welding. In some other embodiments, the first sealing member 50 and the first cover body 20 can be integrally formed, that is, the first sealing member 50 and the first cover body 20 are an integral structure.

[0047] In other embodiments, the first seal 50 is connected to the heating module 40. Specifically, in some embodiments, the first seal 50 can be connected to the heating module 40 in a detachable connection manner, thereby facilitating the removal and replacement of the first seal 50 when it is damaged (e.g., worn or aged). Among them, the detachable connection manner includes but is not limited to snap-on or threaded connection. In other embodiments, the first seal 50 can be connected to the heating module 40 in a non-detachable connection manner, thereby improving the bonding strength between the first seal 50 and the heating module 40, preventing the first seal 50 from falling off from the heating module 40 during use of the aerosol generating device 1000, and ensuring the sealing effect of the first seal 50 on the gap between the first cover 20 and the heating module 40. Among them, the non-detachable connection manner includes but is not limited to bonding or welding. In some further embodiments, the first seal 50 and the heating module 40 can be integrally formed, that is, the first seal 50 and the heating module 40 are an integral structure.

[0048] It can be understood that, in some embodiments, the second seal 60 is connected to the second cover body 30; or the second seal 60 is connected to the heating module 40, wherein the connection method between the second seal 60 and the second cover body 30 is basically the same as the connection method between the first seal 50 and the first cover body 20; the connection method between the second seal 60 and the heating module 40 is basically the same as the connection method between the first seal 50 and the heating module 40, which will not be repeated here.

[0049] In other embodiments, the first seal 50 may also be unconnected to both the first cover 20 and the heating module 40. Specifically, when the first cover 20 is connected to the bracket 10 and the heating module 40 is accommodated in the accommodating cavity 101, the first cover 20 and the heating module 40 can jointly clamp the first seal 50 to achieve the installation and fixation of the first seal 50. In this case, the first seal 50 can also seal the gap between the first cover 20 and the heating module 40. Correspondingly, the second seal 60 may also be unconnected to both the second cover 30 and the heating module 40. Specifically, when the second cover 30 is connected to the bracket 10 and the heating module 40 is accommodated in the accommodating cavity 101, the second cover 30 and the heating module 40 can jointly clamp the second seal 60 to achieve the installation and fixation of the second seal 60. In this case, the second seal 60 can also seal the gap between the second cover 30 and the heating module 40.

[0050] See also Figure 1 and Figure 2In some embodiments, the assembly steps of the heating component 100 (only taking the first sealing member 50 connected to the first cover body 20 and the second sealing member 60 connected to the second cover body 30 as an example) may include: first, the first sealing member 50 is connected to the first cover body 20, and the second sealing member 60 is connected to the second cover body 30; then, the first cover body 20 and the first sealing member 50 are connected to one end of the heating module 40 together, and the second cover body 30 and the second sealing member 60 are connected to the other end of the heating module 40 together; then, the bracket 10 is sleeved with the first cover body 20 and the heating module 40 from one end of the first cover body 20 along the axial direction X, so that the heating module 40 is accommodated in the accommodating cavity 101, and the first end 11 of the bracket 10 is connected to the first cover body 20, and the second end 13 of the bracket 10 is connected to the second cover body 30, thereby completing the assembly of the heating component 100, at this time, the first sealing member 50 can seal the gap between the heating module 40 and the first cover body 20, and the second sealing member 60 can seal the gap between the heating module 40 and the second cover body 30.

[0051] It can be understood that the assembly steps of the heating component 100 in the above embodiment are only exemplary. In other embodiments, the assembly steps of the heating component 100 can also be in other forms, which will not be described in detail here.

[0052] In some embodiments, the first cover 20 includes a first end 201 and a second end 203 opposite to each other, and the first end 201 of the first cover 20 is detachably connected to the first end 11 of the bracket 10. The bracket 10 is provided with a first opening 103 and a second opening 105, the first opening 103 is located at the first end 11 of the bracket 10, and the second opening 105 is located at the second end 13 of the bracket 10, and the first opening 103 and the second opening 105 are both used to connect the accommodating cavity 101 with the outside, and the first cover 20 includes a peripheral wall located in the first opening 103. The width of the second opening 105 is greater than the maximum width of the outer contour of the first cover 20; the width of the first opening 103 is greater than the width of any outer contour between the peripheral wall and the second end 203 of the first cover 20; the width of the accommodating cavity 101 is greater than the maximum width of the outer contour of the first cover 20.

[0053] Specifically, in some embodiments, when the cross-sectional shapes of the first opening 103, the second opening 105 and the accommodating cavity 101 are all circular, the width of the first opening 103 is the diameter of the first opening 103, the width of the second opening 105 is the diameter of the second opening 105, and the width of the accommodating cavity 101 is the diameter of the cross-sectional shape of the accommodating cavity 101. Among them, the width of the second opening 105 and the width of the accommodating cavity 101 are both greater than the maximum width of the outer contour of the first cover body 20, thereby enabling the bracket 10 to move along the axial direction X from the second end 203 of the first cover body 20 toward the second cover body 30, and because the width of the first opening 103 is greater than the width of any outer contour between the peripheral wall and the second end 203 of the first cover body 20, therefore, when the bracket 10 moves along the axial direction X from the second end 203 of the first cover body 20 toward the second cover body 30, when the first end 11 of the bracket 10 abuts against the peripheral wall of the first cover body 20, the first end 11 of the bracket 10 is connected to the first cover body 20, and at this time, the heating module 40 is located in the accommodating cavity 101, and the second end 13 of the bracket 10 is connected to the second cover body 30.

[0059] Specifically, in some embodiments, the first cover 20 is provided with a third groove connected to the first cavity 21, and the third groove is recessed from the first end 201 of the first cover 20 toward the second end 203 of the first cover 20, wherein the second abutting surface 25 is the bottom wall of the third groove, and the inner wall of the first cavity 21 includes the side wall of the third groove. When the first cover 20 is connected to the heating module 40, when the heating module 40 abuts against the second abutting surface 25, that is, when the heating module 40 abuts against the bottom wall of the third groove, the heating module 40 is installed in place in the first cavity 21. It should be noted that when the heating module 40 abuts against the bottom wall of the third groove, the first sealing member 50 is located between the outer peripheral wall of the heating module 40 (the side of the heating module 40 facing the bracket 10) and the side wall of the first groove, thereby, the first sealing member 50 can seal the gap between the heating module 40 and the first cover 20.

[0060] In some embodiments, the inner wall of the second cavity 31 is provided with a second abutment surface 35 , and the second abutment surface 35 is used to abut against the heating module 40 to ensure that the heating module 40 is installed in place in the second cavity 31 .

[0061] Specifically, in some embodiments, the second cover 30 is provided with a fourth groove communicating with the second cavity 31, and the fourth groove is recessed from the first end 301 of the second cover 30 toward the second end 303 of the second cover 30, wherein the second abutting surface 35 is the bottom wall of the fourth groove, and the inner wall of the second cavity 31 includes the side wall of the fourth groove. When the second cover 30 is connected to the heating module 40, when the heating module 40 abuts against the second abutting surface 35, that is, when the heating module 40 abuts against the bottom wall of the fourth groove, the heating module 40 is installed in place in the second cavity 31. It should be noted that when the heating module 40 abuts against the bottom wall of the fourth groove, the second sealing member 60 is located between the outer peripheral wall of the heating module 40 and the side wall of the second groove, thereby, the second sealing member 60 can seal the gap between the heating module 40 and the second cover 30.

[0062] See also Figure 3In some embodiments, the first seal 50 includes a main body 51, which is arranged around the outer peripheral wall of the heating module 40; the second seal 60 includes a main body 61, which is arranged on the outer peripheral wall of the heating module 40. Specifically, in some embodiments, when the heating component 100 is assembled, the main body 51 abuts against the first abutting surface 23 and is located between the side wall of the first cavity 21 (the side wall of the first groove) and the outer peripheral wall of the heating module 40; the main body 61 abuts against the first abutting surface and is located between the second cavity 31 (the side wall of the second groove) and the outer peripheral wall of the heating module 40. Therefore, the arrangement of the first seal 50 and the second seal 60 can reduce or even prevent aerosol leakage to the outside of the heating module 40, thereby ensuring the normal operation of the heating module 40, extending the service life of the heating module 40, and improving the safety of the use of the heating component 100.

[0063] Furthermore, in some embodiments, the first seal 50 may also include an abutment portion 55, which extends from the main body portion 51 toward the heating module 40, and the abutment portion 55 abuts against the outer peripheral wall of the heating module 40. Therefore, compared with the main body 61 directly abutting against the outer peripheral wall of the heating module 40, the setting of the abutment portion 55 can increase the force applied by the first seal 50 to the outer peripheral wall of the heating module 40, thereby enhancing the sealing effect of the first seal 50 on the gap between the heating module 40 and the first cover body 20. Correspondingly, the second seal 60 may also include a resistance portion 65, and the resistance portion 65 extends from the main body portion 61 toward the heating module 40, and the resistance portion 65 abuts against the outer peripheral wall of the heating module 40. Therefore, compared with the main body 51 directly abutting against the outer peripheral wall of the heating module 40, the setting of the resistance portion 65 can increase the force applied by the second seal 60 on the outer peripheral wall of the heating module 40, thereby enhancing the sealing effect of the second seal 60 on the gap between the heating module 40 and the second cover body 30.

[0064] Furthermore, in some embodiments, the first seal 50 may further include an extension portion 53, which extends from the main body 51 in a direction away from the heating module 40; the second seal 60 may further include an extension portion 63, which extends from the main body 61 in a direction away from the heating element. Specifically, in some embodiments, when the heating component 100 is assembled, the extension portion 53 abuts against the first end 201 of the first cover 20, and the extension portion 63 abuts against the first end 301 of the second cover 30. Therefore, the arrangement of the extension portion 53 and the extension portion 63 can facilitate the installation and positioning of the first seal 50 and the second seal 60, improve the installation accuracy of the first seal 50 and the second seal 60, thereby reducing the assembly defect rate of the heating component 100 while also improving the assembly efficiency of the heating component 100.

[0065] See also Figure 3 In some embodiments, the first cover 20 includes a coupling portion 27, and the second cover 30 includes a coupling portion 37. The bracket 10 includes a first matching portion 15 and a second matching portion 17, the first matching portion 15 matches with the coupling portion 27 to detachably connect the bracket 10 and the first cover 20, and the second matching portion 17 matches with the coupling portion 37 to detachably connect the bracket 10 and the second cover 30, thereby, the first matching portion 15 matches with the coupling portion 27, and the second matching portion 17 matches with the coupling portion 37 to jointly realize the overall connection and fixation of the heating component 100.

[0066] Specifically, in some embodiments, the first matching portion 15 and the connecting portion 27 can be matched in a manner such as a protrusion matching a groove or a buckle matching a slot, etc.; the second matching portion 17 and the connecting portion 37 can be matched in a manner such as a protrusion matching a groove or a buckle matching a slot, etc. It should be noted that, please refer to the following. Figure 2 In some embodiments, when the bracket 10 is connected to the first cover body 20 and the second cover body 30, the bracket 10 can move along the second end 203 of the first cover body 20 toward the second cover body 30 and be sleeved on the outer sides of the first cover body 20 and the second cover body 30, so that the first matching portion 15 matches with the connecting portion 27, and the second matching portion 17 matches with the connecting portion 37; or the bracket 10 can move along the second end 303 of the second cover body 30 toward the first cover body 20 and be sleeved on the outer sides of the first cover body 20 and the second cover body 30, so that the first matching portion 15 matches with the connecting portion 27, and the second matching portion 17 matches with the connecting portion 37. The embodiments of the present application are described by taking the example that the bracket 10 moves along the second end 203 of the first cover body 20 toward the second cover body 30 and is sleeved on the outer sides of the first cover body 20 and the second cover body 30.

[0067] In some embodiments, the coupling portion 37 may be a protrusion, which protrudes and extends from the side wall of the second cover body 30 in a direction away from the central axis of the second cover body 30; the second matching portion 17 may be a groove, which is provided on the side wall of the bracket 10; the coupling portion 27 is the outer peripheral wall of the first cover body 20, and the first matching portion 15 is a positioning protrusion, which extends from the bracket 10 in the direction of the central axis of the bracket 10. When the heating component 100 is assembled, the protrusion cooperates with the groove, and the positioning protrusion abuts against the outer peripheral wall of the first cover body 20. It should be noted that in some embodiments, a plurality of protrusions may be provided. Among them, the quantitative relationship between the groove and the protrusion may be one-to-one or one-to-many. For example, one groove may correspond to one protrusion; for another example, one groove may correspond to multiple protrusions.

[0068] See also Figure 3In some embodiments, a contact surface 28 is formed on the outer peripheral wall of the first cover body 20, and the contact surface 28 is used to abut against the first matching portion 15 to ensure that the bracket 10 and the first cover body 20 are connected in place.

[0069] Specifically, in some embodiments, the first cover body 20 is provided with a resistance groove, which is arranged on the outer peripheral wall of the first cover body 20 and spaced from the first cavity 21, and the resistance groove is recessed from the second end 2903 of the first cover body 20 toward the first end 2901 of the first cover body 20, wherein the bottom wall of the resistance groove is the resistance surface 28. When the bracket 10 is connected to the first cover body 20, when the first matching portion 15 is in contact with the resistance surface 28, that is, when the first matching portion 15 is in contact with the bottom wall of the resistance groove, the bracket 10 is connected to the first cover body 20 in place.

[0070] See also Figure 2 and Figure 4 The aerosol generating device 1000 of the embodiment of the present application includes a housing 200 and a heating component 100 of any of the above-mentioned embodiments, and the heating component 100 is installed in the housing 200 .

[0071] In the aerosol generating device 1000 of the embodiment of the present application, the first cover body 20 and the second cover body 30 are respectively installed at the opposite ends of the heating module 40 along the axial direction X, and the bracket 10 can be sleeved with the first cover body 20 and the heating module 40 from one end of the first cover body 20 along the axial direction X, and the first end 11 of the bracket 10 is connected to the first cover body 20, and the second end 13 of the bracket 10 is connected to the second cover body 30. Therefore, compared with the cover body (including the first cover body 20 and / or the second cover body 30) and the bracket 10 as an integral structure, the installation process between the opposite ends of the heating module 40 and other structures in this embodiment is visible, thereby preventing the heating module 40 from being blindly installed, resulting in inaccurate installation and positioning, reducing the assembly defect rate of the heating component 100, and thereby ensuring the normal operation of the aerosol generating device 1000.

[0072] Please combine Figure 5 and Figure 6 In some embodiments, the aerosol generating device 1000 may further include a mounting bracket 300 , and the mounting bracket 300 is disposed in the housing 200 .

[0073] Specifically, in some embodiments, the housing 200 is provided with a through hole 210 communicating with the accommodating chamber 101, and the aerosol generating substrate can extend into the accommodating chamber 101 through the through hole 210. The mounting bracket 300 includes a main bracket 310, a slider bracket 320 and a display bracket 330. The slider bracket 320 is disposed on the top of the main bracket 310 ( Figure 5 The display support 330 is disposed at the top of the main support 310 and the bottom of the main support 310 ( Figure 5 The slider bracket 320 is used to carry the slider 321, and the slider 321 can move relative to the slider bracket 320 to selectively open or close the communication between the through hole 210 and the accommodating cavity 101. The heating component 100 can be connected to the mounting bracket 300 (including the main bracket 310, the slider bracket 320 and the display bracket 330) in a detachable or non-detachable connection manner. The detachable connection manner includes but is not limited to a snap-on or threaded connection, etc.; the non-detachable connection manner includes but is not limited to bonding or welding, etc.

[0074] See also Figure 2 , Figure 5 and Figure 6 In some embodiments, the second cover 30 may be provided with a mounting groove 39, which is recessed from the outer peripheral wall of the second cover 30 toward the central axis of the second cover 30, and the mounting groove 39 cooperates with the mounting bracket 300 to install the heating component 100 in the housing 200. Specifically, in some embodiments, at least one of the main bracket 310, the slider bracket 320 and the display bracket 330 may be provided with a connecting protrusion, which can be extended into the mounting groove 39, so that the heating component 100 can be detachably connected to the mounting bracket 300.

[0075] In some embodiments, the first cover body 20 may include a protrusion 29, which extends from the second end 2903 of the first cover body 20 in a direction away from the central axis of the first cover body 20, and the protrusion 29 cooperates with the mounting bracket 300 to install the heating component 100 in the housing 200. Specifically, in some embodiments, at least one of the main bracket 310, the slider bracket 320 and the display bracket 330 may be provided with a connecting groove, and the protrusion 29 can extend into the connecting groove, so that the heating component 100 can be detachably connected to the mounting bracket 300.

[0076] As can be seen from the above, the bracket 10 moves along the second end 203 of the first cover body 20 toward the second cover body 30 and is sleeved on the outside of the first cover body 20 and the second cover body 30. Therefore, if the cross-sectional dimension d1 of the protrusion 29 is greater than the cross-sectional dimension d2 of the positioning opening (first opening 103) formed by the first matching portion 15 of the bracket 10, the protrusion 29 may hinder the movement of the bracket 10 along the second end 203 of the first cover body 20 toward the second cover body 30, thereby causing the bracket 10 to be unable to connect with the first cover body 20 and the second cover body 30, thereby affecting the normal assembly of the heating component 100. Therefore, in some embodiments, the cross-sectional dimension d1 of the protrusion 29 is smaller than the cross-sectional dimension d2 of the positioning opening formed by the first matching portion 15 of the bracket 10, thereby ensuring that the bracket 10 can move along the second end 203 of the first cover body 20 toward the second cover body 30, thereby ensuring the normal assembly of the heating component 100.

[0077] In some embodiments, the heating assembly 100 may further include a sealing ring 70, which is disposed between the second cover 30 and the mounting bracket 300, and is used to seal the gap between the second cover 30 and the mounting bracket 300. The provision of the sealing ring 70 can prevent the aerosol in the accommodating cavity 101 from entering the housing 200 through the gap between the second cover 30 and the mounting bracket 300, causing damage to the structure inside the housing 200, thereby ensuring the normal operation of the aerosol generating device 1000. In addition, the provision of the sealing ring 70 can also ensure the amount of aerosol generated, thereby improving the user's suction taste. It should be noted that, in some embodiments, the material of the sealing ring 70 includes but is not limited to rubber, plastic or silicone.
