Description

[0002] An aerosol-generating device (AGD) uses heated gas to create a hot air flow, which in turn heats an aerosol-generating product to produce an aerosol for inhalation.

The elastic force provided by the mutual abutment between the electrodes of the heating component and the main body component is relatively small, which makes it easy for the heating component to shake, resulting in unstable electrical connection between the heating component and the main body component, thereby affecting the operation of the heating component.

[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] See also Figures 1 to 3The present application provides an aerosol-generating device 100, comprising a main assembly 10 and a heating assembly 20. The heating assembly 20 is detachably disposed within the main assembly 10 and is used to heat an aerosol-generating article to generate an aerosol for inhalation by a user. The main assembly 10 includes a chamber 121 with an opening 111 facing laterally. The main assembly 10 also includes an elastic member 13, a battery 14, and a first electrode 15 electrically connected to the battery 14. At least a portion of the elastic member 13 and at least a portion of the first electrode 15 are exposed within the chamber 121. The heating assembly 20 includes a housing 21 for accommodating at least a portion of the aerosol-generating article, a heating element 22 for heating the aerosol-generating article, and a second electrode 23 electrically connected to the heating element 22. The heating assembly 20 is removably housed within the chamber 121 and is located between the elastic member 13 and the first electrode 15. The first electrode 15 abuts against the second electrode 23 to form an electrical connection, thereby enabling the battery 14 to provide electrical energy to the heating element 22 in the heating assembly 20. The aerosol generating device 100 of the embodiment of the present application disposes the heating component 20 between the elastic member 13 and the first electrode 15, so that the heating component 20 is clamped between the elastic member 13 and the first electrode 15. Under the elastic force provided by the elastic member 13, the first electrode 15 and the second electrode 23 of the heating component 20 maintain stable and good abutment, thereby ensuring that the battery 14 stably provides electrical energy to the heating component 20.

[0030] In some embodiments, the heating element 22 includes an internal heating element 22 for heating the interior of the aerosol-generating article, an external heating element 22 for heating the exterior of the aerosol-generating article, and / or an air heating element 22 disposed upstream of the receiving cavity 21 and for heating air. The heating element 22 may generate heat using, but is not limited to, electromagnetic heating and resistive heating.

[0031] In some embodiments, the first electrode 15 elastically abuts the second electrode 23. At least a portion of the first electrode 15 can be elastically deformed, and / or at least a portion of the second electrode 23 can be elastically deformed. When the heating assembly 20 is assembled into the cavity 121 of the main assembly 10, the first electrode 15 and the second electrode 23 elastically abut against each other. This elastic abutment of the elastic member 13 can further enhance the connection stability between the heating assembly 20 and the battery 14.

[0032] In some embodiments, see Figures 3 to 5The aerosol generating device 100 further includes a first retaining member 30, which is disposed at an end portion of the main body assembly 10. The elastic member 13 includes a first deformable member 131 and a second retaining member 132 for abutting the heating assembly 20. The second retaining member 132 is configured to be movable longitudinally relative to the first retaining member 30, i.e., the second retaining member 132 can be moved longitudinally closer to the first retaining member 30 to increase the longitudinal space of the chamber 121, or the second retaining member 132 can be moved longitudinally away from the first retaining member 30 to reduce the longitudinal space of the chamber 121. The first deformable member 131 is connected between the first retaining member 30 and the second retaining member 132 and is configured to be elastically deformable in the longitudinal direction.

[0033] When the second retaining member 132 abuts against the end of the heating component 20, the two can be in surface contact to increase the contact area between the elastic member 13 and the heating component 20, thereby improving the connection stability between the elastic member 13 and the heating component 20, and helping to prevent the heating component 20 in the chamber 121 from shaking laterally.

[0034] In some embodiments, the first deformable member 131 may be a spring, with its two ends respectively connected to the first retaining member 30 and the second retaining member 132. In other embodiments, the first deformable member 131 may also be a deformable structure such as a spring. It is understood that in some embodiments, the second retaining member 132 may be omitted. In this case, one end of the first deformable member 131 is connected to the first retaining member 30, and the other end of the first deformable member 131 abuts the end of the heating assembly 20 to retain the heating assembly 20 in the chamber 121.

[0035] In some embodiments, see Figure 4 and Figure 5 The main body assembly 10 is provided with a first air inlet channel 16 in fluid communication with the outside air, and an outlet 161 of the first air inlet channel 16 is provided on the second retaining member 132. The heating assembly 20 is provided with a second air inlet channel 24 in fluid communication with the accommodating chamber 21. The aerosol generating device 100 further includes a sealing assembly 40, which is provided between the second retaining member 132 and the heating assembly 20 to ensure sealed communication between the outlet of the first air inlet channel 16 and the second air inlet channel 24.

[0036] like Figure 5 As shown by the hollow arrow in the middle dashed line, the external air flows from the first air inlet channel 16 through its outlet 161 to the second air inlet channel 24 and then flows into the accommodating chamber 21 .

[0037] When the heating element 22 comprises the above-mentioned air heating element, the air heating element can heat at least part of the air in the second air inlet channel 24, and then the hot air flows into the aerosol-generating article to heat the aerosol-generating article.

[0038] When the heating element 22 includes the aforementioned internal heating element, at least a portion of the internal heating element is disposed within the accommodating cavity 21. Thus, when at least a portion of the aerosol-generating article is inserted and retained within the accommodating cavity 21, at least a portion of the internal heating element can be inserted into the aerosol-generating article. In this example, at least a portion of the second air inlet passage 24 can be located within the accommodating cavity 21, allowing air to flow along the boundary wall of the accommodating cavity 21 toward the bottom of the aerosol-generating article and then into the interior of the aerosol-generating article.

[0039] When the heating element 22 includes the external heating element described above, the external heating element is disposed around the periphery of the accommodating cavity 21. In this example, at least a portion of the second air inlet passage 24 may be located outside the external heating element.

[0040] By providing a sealing assembly 40 between the second retaining member 132 and the end of the heating assembly 20 , the gap between the second retaining member 132 and the heating assembly 20 after assembly can be sealed, thereby maintaining the airtightness of the first air inlet channel 16 and the second air inlet channel 24 after splicing.

[0041] In some embodiments, see Figure 4 and Figure 5 The sealing assembly 40 includes a first sealing member 41 and a second sealing member 42. Both the first sealing member 41 and the second sealing member 42 are disposed on the second retaining member 132. The first sealing member 41 and the second sealing member 42 are nested and spaced apart in the radial direction of the second retaining member 132. This seals both the inside and outside of the first air inlet passage 16 and the second air inlet passage 24, preventing air leakage from both inside and outside.

[0042] In some embodiments, see Figure 4 and Figure 5 The first retaining member 30 has a first through hole 31, and the second retaining member 132 has a second through hole 1321. The second through hole 1321 is located between the first through hole 31 and the accommodating chamber 21. The second through hole 1321 connects the first through hole 31 and the accommodating chamber 21, thereby connecting the accommodating chamber 21 with the outside world. At least a portion of the aerosol-generating article sequentially passes through the first through hole 31 and the second through hole 1321 to enter the accommodating chamber 21 and be retained.

[0043] The first retaining member 30 or the second retaining member 132 defines an entrance to the first air inlet channel 16, which is fluidically connected to the outside air via the first through-hole 31. This structure prevents the entrance of the first air inlet channel 16 from being exposed to the outside world, thereby improving the aesthetics of the aerosol generating device 100 and preventing dust and moisture from entering the first channel directly through the entrance.

[0044] It can be understood that when the entrance of the first air inlet channel 16 is opened on the first retaining member 30, the aerosol generating product can cooperate with at least a partial gap of the first retaining member 30 in the first through hole 31, so that at least a part of the first through hole 31 can connect the outside air and the entrance of the first air inlet channel 16, thereby facilitating the outside air to enter the first air inlet channel 16 through the first through hole 31, the gap between the aerosol generating product and the first retaining member 30, and the entrance in turn.

[0045] When the entrance of the first air inlet channel 16 is opened on the second retaining member 132, the aerosol generating product can fit in the gap with the first retaining member 30 in the first through hole 31, and the aerosol generating product can fit in the gap with at least a part of the second retaining member 132 in the second through hole 1321, so that the first through hole 31 can connect the outside air and at least a part of the second through hole 1321, and at the same time, at least a part of the second through hole 1321 can connect the first through hole 31 and the entrance of the first air inlet channel 16, so as to facilitate the outside air to enter the first air inlet channel 16 through the first through hole 31, the gap between the aerosol generating product and the first retaining member 30, the gap between the aerosol generating product and the second retaining member 132, and the entrance in sequence.

[0046] In some embodiments, see Figure 4 and Figure 5 One of the first retaining member 30 and the second retaining member 132 is provided with a guide groove 32 extending longitudinally, and the other is provided with a boss 1322, which is configured to slide along the guide groove 32, and a part of the guide groove 32 constitutes the entrance of the first air intake channel 16.

[0047] By providing a boss 1322 and a guide groove 32 on the first retaining member 30 and the second retaining member 132 respectively, the guide groove 32 has a guiding effect on the boss 1322, so that the second retaining member 132 can slide back and forth relative to the first retaining member 30 in the longitudinal direction, and can also prevent the second retaining member 132 from rotating.

[0048] The length of the guide groove 32 is greater than the length of the boss 1322, so that the space in the guide groove 32 not occupied by the boss 1322 can constitute the entrance of the first air intake channel 16. Therefore, the guide groove 32 not only guides the boss 1322, but also allows air to enter the first air intake channel 16. There is no need to open an additional entrance specifically for air intake on the first retaining member 30 or the second retaining member 132, thereby reducing the processing technology.

[0049] In such Figure 4 and Figure 5In the illustrated embodiment, the first retaining member 30 includes a first tubular structure extending longitudinally, which defines at least a portion of the boundary of the first through hole 31. The second retaining member 132 includes a second tubular structure extending longitudinally, which defines at least a portion of the boundary of the second through hole 1321. At least one of the first tubular structure and the second tubular structure is provided with the guide groove 32, and at least one of the first tubular structure and the second tubular structure has the boss 1322. The first tubular structure and the second tubular structure are nested and slidably connected. When the boss 1322 moves along the guide groove 32, the first tubular structure and the second tubular structure slide relative to each other. A sealing ring can be provided between the first tubular structure and the second tubular structure to prevent airflow from passing between the first tubular structure and the second tubular structure.

[0050] In some embodiments, see Figure 5 At least a portion of the first air inlet channel 16 is disposed between the first retaining member 30 and the second retaining member 132. When the second retaining member 132 moves longitudinally relative to the first retaining member 30, the length or space of the first air inlet channel 16 changes accordingly. In particular, when the second retaining member 132 moves toward the first retaining member 30 during removal of the heating assembly 20, the space of the first air inlet channel 16 decreases, thereby allowing the airflow containing aerosol that has reflowed into the first air inlet channel 16 to be discharged from the first air inlet channel 16. This helps prevent the first air inlet channel 16 from being blocked and also helps prevent the first deformable member 131, which is disposed between the first retaining member 30 and the second retaining member 132, from being corroded by the aerosol or becoming adhered to by the aerosol.

[0051] In such Figure 4 In the illustrated embodiment, the second retaining member 132 includes a third tubular structure extending longitudinally. The third tubular structure is disposed circumferentially around the second tubular structure. The outlet 161 of the first air inlet passage 16 can be disposed between the third tubular structure and the second tubular structure. Both the third tubular structure and the second tubular structure can abut the heating assembly 20.

[0052] In some embodiments, see Figure 5 The heating assembly 20 includes a housing 25 that defines a portion of the accommodating cavity 21. The heating element 22 is disposed within the housing 25. The housing 25 prevents a user from being burned by the heating element 22 when removing the heating assembly 20. The elastic member 13 abuts against the housing 25.

[0053] As an example, the heating element 22 includes a tubular heating element 22 arranged in the shell 25, the tubular heating element 22 defines at least part of the boundary of the accommodating cavity 21, and the tubular heating element 22 is capable of clamping a part of the aerosol generating article, wherein the tubular heating element 22 is an external heating element.

[0054] At least a portion of the second air inlet passage 24 can be disposed between the housing 25 and the tubular heating element 22, thereby increasing the thermal resistance between the housing 25 and the tubular heating element 22 and helping to reduce the temperature on the housing 25. Furthermore, when air flows through the second air inlet passage 24, it absorbs heat within the second air inlet passage 24, thereby preheating the air before entering the accommodating cavity 21.

[0055] As an example, the heating assembly 20 includes a tubular body disposed within the housing 25 and defining at least a portion of the accommodating chamber 21, with at least a portion of the second air inlet passage 24 disposed between the housing 25 and the tubular body. The tubular body may include, but is not limited to, an insulated tube having a negative pressure spacer layer within its wall, a metal tube, a ceramic tube, an injection-molded tube, and the like. The tubular body may be disposed between the heating element 22 and the housing 25. The heating element 22 may be disposed between the tubular body and the housing 25. The heating element 22 may be connected to the tubular body. The heating element 22 may be spaced apart from the tubular body. At least a portion of the second air inlet passage 24 may be disposed between the housing 25 and the tubular body.

[0056] In some embodiments, see Figure 5 The main assembly 10 includes a housing 11 and a bracket 12, which is disposed inside the housing 11. A portion of the second retaining member 132 is disposed between the bracket 12 and the first retaining member 30 to limit longitudinal movement of the second retaining member 132 between the bracket 12 and the first retaining member 30.

[0057] The bracket 12 can support the heating assembly 20, and the heating assembly 20 can be held inside the housing 11 by the bracket 12. Furthermore, a cavity 121 can be formed in the bracket 12. The first electrode 15 can be fixed to the bracket 12, and a portion of the first electrode 15 can protrude from the bracket 12 so as to be located in the cavity 121.

[0058] In some embodiments, the first deformable member 131 is configured to remain in a compressed state and to be further compressed during the process of removing the heating assembly 20 from the chamber 121 and the process of installing the heating assembly 20 into the chamber 121 .

[0059] During the process of assembling the heating component 20 into the chamber 121, the first deformable member 131 is further compressed, and the second retaining member 132 moves toward the direction close to the first retaining member 30, so that the chamber 121 has a larger receiving space, which helps to assemble the heating component 20 into the receiving space.

[0060] After the heating assembly 20 is assembled into the chamber 121, the longitudinal length of the receiving space can be substantially the same as the longitudinal length of the heating assembly 20. Alternatively, before or after the heating assembly 20 is assembled into the chamber 121, the longitudinal distance between the second retaining member 132 and the first electrode 15 can be substantially the same as the longitudinal length of the heating assembly 20. This can reduce the size of the aerosol generating device.

[0061] During the process of assembling the heating component 20 into the chamber 121, the proximal end of the heating component 20 can be tilted against the second retaining member 132 to drive the second retaining member 132 to move toward the direction close to the first retaining member 30, so that the first deformable member 131 is further compressed; then the heating component 20 is sent into the receiving space of the chamber 121, and the orientation of the heating component 20 is adjusted so that the second electrode 23 is aligned with the first electrode 15; then the heating component 20 is released, and under the elastic restoring force of the first deformable member 131, the second retaining member 132 moves in the direction away from the first retaining member 30 and acts on the heating component 20, so that the second electrode 23 stably abuts against the first electrode 15.

[0062] In some embodiments, the first deformable member 131 is configured to remain in a compressed state such that the bracket 12 abuts the second retaining member 132 both when the heating assembly 20 is retained in the chamber 121 and after the heating assembly 20 is removed from the chamber 121 .

[0063] Before the heating assembly 20 is assembled into the chamber 121, the bracket 12 abuts the second retaining member 132. However, because the longitudinal length of the receiving space can be roughly the same as the longitudinal length of the heating assembly 20, and the first electrode 15 is partially located in the chamber 121, the longitudinal spacing between the second retaining member 132 and the first electrode 15 is smaller than the longitudinal length of the heating assembly 20. Therefore, the proximal end of the heating assembly 20 can first be tilted against the second retaining member 132. After the second retaining member 132 disengages from the bracket 12 and gives way, increasing the receiving space, the orientation of the heating assembly 20 can be adjusted. Subsequently, under the elastic restoring force of the first deforming member 131, the second retaining member 132 returns to its original position and is once again supported by the bracket 12. Simultaneously, the second retaining member 132 compresses the heating assembly 20, causing the second electrode 23 to stably abut the first electrode 15.

[0064] In some embodiments, see Figure 6The heating assembly 20 includes a housing 25 and a handle 26 connected to the housing 25. The handle 26 is disposed toward the opening 111 of the chamber 121. The handle 26 is configured to be flippable relative to the housing 25 so that the user can pull it laterally to remove the heating assembly 20 from the chamber 121. By providing a rotatable handle 26 on the outside of the housing 25, the user can rotate and hold the handle 26 to assemble the heating assembly 20 into the chamber 121 or remove the heating assembly 20 from the chamber 121. The structure of the handle 26 facilitates the user's grip on the heating assembly 20 and effectively improves the efficiency of assembling and disassembling the heating assembly 20. After the heating assembly 20 is assembled in the chamber 121, the handle 26 can be rotated and attached to the surface of the housing 25 to prevent the handle 26 from occupying too much space in the chamber 121.

[0065] In some embodiments, the handle 26 is disposed near the end of the heating assembly 20 abutted by the elastic member 13; or the handle 26 is disposed near the end where the second electrode 23 is located. As can be seen from the foregoing, the tilted state of the heating assembly 20 facilitates its assembly or disassembly. Therefore, disposing the handle 26 at the end of the heating assembly 20 further improves the efficiency of assembly and disassembly of the heating assembly 20.
