The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] Before introducing the aerosol generating devices in detail, please refer to Figures 1 to 3 First, the heating object of the aerosol generating device, i.e., the aerosol generating rod 100, is described. One end of the aerosol generating rod 100 is a suction end 101 for inhaling aerosol, and the other end is an air inlet end 102. The air inlet end 102 supplies gas to enter the aerosol generating rod 100 during inhalation. In one embodiment, the suction end 101 of the aerosol generating rod 100 has a filter element (not shown in the figure). The filter element (not shown in the figure) can adopt various existing or future feasible methods, such as sponge, cigarette holder paper, etc. In one embodiment, the aerosol generating rod 100 contains an aerosol generating matrix, and the aerosol generating matrix is ​​an aerosol filament or an aerosol sheet for generating aerosol. When in use, the aerosol generating rod 100 is inserted into the aerosol generating device, and the aerosol generating matrix is ​​heated by the aerosol generating device to generate an aerosol.

[0037] In one embodiment, please refer to Figures 1 to 3 The aerosol generating device includes a power supply component and a heating component 1, and the power supply component supplies power to the heating component 1. In one embodiment, the power supply component includes a power source 2, and the power source 2 includes a battery. The power supply component and the heating component 1 can be integrated together, for example, the power supply component is integrated in the heating component 1. In one embodiment, the power supply component and the heating component 1 are both modularly configured, and in this case, the power supply component and the heating component 1 are detachably fixed by means of magnetic attraction, snap-on connection, etc., and after the power supply component or the heating component 1 is damaged, it can be replaced separately.

[0038] In one embodiment, please refer to Figures 3 to 6The heating assembly 1 includes a shell 11 and a heating tube 12. The shell 11 has a housing 111 for accommodating the aerosol generating rod 100 and an insulating chamber 112 outside the housing 111. The heating tube 12 separates the insulating chamber 112 from the housing 111. The insulating chamber 112 can play a role in heat insulation, reducing the heat transferred to the outside by the heating tube 12. The heating assembly 1 includes a wire 13, which includes a conductor 131 and a sleeve 132. The sleeve 132 is sleeved around the conductor 131. The wire 13 is conductively connected to the heating tube 12 through the conductor 131, and the conductor 131 is connected to the outside of the heating tube 12. One end of the wire 13 is in the insulating chamber 112 and connected to the heating tube 12, and the other end is outside the insulating chamber 112. The conductor 13 includes a first section 133 in the heat-insulating cavity 112 and a second section 134 outside the heat-insulating cavity 112 . The second section 134 is provided with a sealing body 1341 for sealing a gap 135 between the conductor 131 and the sleeve 132 .

[0039] The present application seals the gap 135 between the sleeve 132 and the conductor 131 by the sealing body 1341 on the second section 134. Since the sealing body 1341 is on the second section 134, it is less affected by the heat of the heating element, and the sealing effect of the sealing body 1341 is better. Under the sealing effect of the sealing body 1341, an air column can be formed between the conductor 131 and the sleeve 132, and aerosol or aerosol-generated oil is less likely to enter between the sleeve 132 and the conductor 131, thereby improving the problem of oil leakage through the wire 13. In addition, the sealing body 1341 can block the channel between the sleeve 132 and the conductor 131, and the aerosol or oil cannot leak from the channel, further improving the anti-leakage effect.

[0040] Regarding the structure of the heating tube 12, in one embodiment, please refer to Figure 3 and Figure 4 The heating tube 12 includes a heat pipe 121 and a heating element 122. The heating element 122 is installed on the outer wall of the heat pipe 121 or embedded in the heat pipe 121. Specifically, the heating element 122 and the heat pipe 121 can adopt any feasible solution. For example, the heating element 122 can be a resistance wire embedded in the heat pipe 121. In this case, the heat pipe 121 is preferably made of an insulating heat-conducting material. Of course, an insulating layer can also be applied to the outer periphery of the resistance wire. In this case, the heat pipe 121 can also be made of a conductive material. For another example, please refer to Figure 4 and Figure 5, the heating element 122 can also be a heating film printed on the outer peripheral surface of the heat pipe 121. In this case, the heating element 122 and the heat pipe 121 together form a thick film tube, and there is an insulating layer outside the heating film. In this case, the heat pipe 121 can use a metal tube with good thermal conductivity; for example, the heating element 122 can also be a resistance wire wound on the outer wall of the heat pipe 121. The heating tube 12 can also use electromagnetic induction heating. For example, an inductor coil is arranged outside the heat pipe 121, and the heat pipe 121 itself is made of magnetic induction material. In this case, the heat pipe 121 itself is the heating element 122; or a heating element 122 made of magnetic induction material is arranged on the heat pipe 121. The heating element 122 generates heat through electromagnetic induction heating and then transfers it to the heat exchanger through the heat pipe 121 to heat the air.

[0041] Further, in one embodiment, please refer to Figures 3 to 6 The end of the second section 134 away from the first section 133 is the end of the wire 13, and the end of the second section 134 away from the first section 133 is provided with a sealing body 1341, that is, the end of the wire 13 outside the heat insulation cavity 112 is provided with a sealing body 1341. It is easier to implement and simpler to manufacture to provide a sealing body 1341 at the end of the wire 13. In some other embodiments, a sealing body 1341 may also be provided in the middle of the second section 134. In this case, it is necessary to peel off part of the sleeve 132 in the middle of the second section 134, and then use the sealing body 1341 to seal the peeled opening.

[0042] The sealing body 1341 may be in any feasible form. For example, in one embodiment, the sealing body 1341 may be made of sealant, such as filling the end of the wire 13 with sealant to achieve sealing between the sleeve 132 and the wire 13. In some other embodiments, the sealing body 1341 may also be made of insulating rubber, such as directly melting the insulating rubber on the end of the wire 13.

[0043] Further, in one embodiment, the sealing body 1341 is only provided at the end of the wire 13, which has a simpler structure and is more convenient to process. Figure 7 The number of the sealing bodies 1341 may also be at least two, and at least two sealing bodies 1341 are arranged at intervals in the extension direction of the second section 134. Figure 7 , glue is poured into the gap between the sleeve 132 and the wire 13 to form a sealing body 1341.

[0044] Further, in one embodiment, please refer to Figure 3 and Figure 4The heating assembly 1 includes a circuit board 14, one end of the wire 13 is connected to the heating tube 12, and the other end is connected to the circuit board 14. In one embodiment, the housing 11 has a battery space 15, the battery is installed in the battery space 15, and the circuit board 14 is located on one side of the battery space 15, which is convenient for connecting with the battery.

[0045] In one embodiment, please refer to Figure 4 The number of the wires 13 is three, and the three wires 13 are all conductively connected to the circuit board 14 .

[0046] Regarding the installation structure of the heating tube 12, in one embodiment, please refer to Figure 3 and Figure 4 The heating assembly 1 includes a first tube seat 16 and a second tube seat 17, and the heating tube 12 is sandwiched between the first tube seat 16 and the second tube seat 17. The heating assembly 1 also includes a protective sleeve 18, and the protective sleeve 18 is located at the periphery of the heating tube 12. The heat insulation cavity 112 is located between the protective sleeve 18 and the heating tube 12. The heating tube 12 is sandwiched between the first tube seat 16 and the second tube seat 17, which facilitates the installation of the heating tube 12. Further, in one embodiment, please refer to Figure 3 and Figure 4 , the wire 13 passes through the first tube seat 16 and extends out of the insulation cavity 112. In some other embodiments, the wire 13 can also pass through the protective sleeve 18 and extend out of the insulation cavity 112. In some other embodiments, when there are multiple wires 13, part of the wires 13 can pass through the first tube seat 16, and part of the wires 13 can pass through the second tube seat 17 and extend out of the insulation cavity 112.

[0047] In one embodiment, please refer to Figure 3 and Figure 4 The second tube base 17 and the protective cover 18 are integrally formed, and the second tube base 17 has a generation rod through hole 171 for the aerosol generation rod 100 to pass through, and the generation rod through hole 171 is a part of the accommodating cavity 111. The first tube base 16 has an air flow hole 161 for air flow to pass through. The aerosol generation rod 100 is inserted into the accommodating cavity 111. When the aerosol generation rod 100 is inhaled, the outside air enters the aerosol generation rod 100 through the air flow hole 161. In some other embodiments, the second tube base 17 and the protective cover 18 can also be assembled together and fixed by welding, riveting or fasteners.

[0048] Further, in one embodiment, please refer to Figure 3 and Figure 4, at least part of the first tube seat 16 is inserted into the protective sleeve 18, a sealing ring 19 is sleeved on the first tube seat 16, the first tube seat 16 is sealed with the protective sleeve 18 through the sealing ring 19, the wire 13 passes through the first tube seat 16 between the sealing ring 19 and the first tube seat 16, and the sealing ring 19 is in sealing contact with the wire 13. By utilizing the softness of the sealing ring 19, when the wire 13 passes between the sealing ring 19 and the first tube seat 16, the sealing ring 19 can seal the wire 13, thereby simplifying the sealing structure. In some other embodiments, a wire through hole for the wire 13 to pass through can also be added to the first tube seat 16, and a sealing ring 19 is added to the wire 13 through hole to achieve sealing between the first tube seat 16 and the wire 13.

[0049] Further, in one embodiment, please refer to Figure 4 and Figure 5 The first tube base 16 has a sealing groove 162, and the sealing ring 19 is at least partially located in the sealing groove 162. The first tube base 16 has a through groove 163 for the wire 13 to pass through, and the through groove 163 runs through the sealing groove 162. In this way, the stability of the sealing ring 19 can be enhanced through the sealing groove 162, and the sealing ring 19 is not easy to move.

[0050] In one embodiment, the accommodating chamber 111 in the present application has a certain sealing property, which can prevent aerosol and oil from leaking out. When the heating tube 12 starts heating, the aerosol generating matrix is ​​atomized, and the different expansion coefficients of the different materials surrounding the accommodating chamber 111 are different, which will produce a certain gap 135 so that the aerosol or oil in the accommodating chamber 111 leaks into the heat-insulating chamber 112. Since the temperature in the heat-insulating chamber 112 is relatively low, the sealing effect of the heat-insulating chamber 112 can prevent the aerosol or oil from leaking further.

[0051] Due to the influence of temperature in the insulation cavity 112, a tight seal cannot be formed between the conductor 131 and the sleeve 132 in the wire 13. In order to prevent aerosol and oil from leaking from the sleeve 132 along the conductor 131 to the circuit board 14 and causing failure of the circuit board 14, the present application adopts a sealing body 1341 to seal the gap 135 between the sleeve 132 and the conductor 131, and the sealing body 1341 is outside the insulation cavity 112, is less affected by temperature, and has a good sealing effect.

[0052] An embodiment of a heating component, the heating component can be the heating component described in any of the above embodiments, which will not be described in detail.

[0053] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
