[0002] In order to overcome the harmful substances generated by cigarette combustion, cigarette substitutes such as heat-not-burn devices have emerged. By placing an aerosol-forming substrate in a heat-not-burn device, smoke for inhalation is formed under the condition of heat-not-burn.
[0003] In existing heat-not-burn devices, common heating elements are columnar or sheet-shaped heating elements. The columnar heating element has high strength, but small area and poor atomization effect. While the sheet-shaped heating element has low strength and is prone to breakage. Summary of the Invention
[0004] The purpose of this application is to provide a heating element and a heat-not-burn device to solve the disadvantages of the heating element in the prior art.
[0005] One embodiment of this application provides a heating element for a heat-not-burn device, including:
[0006] A housing, including a columnar body and a sheet structure provided on the outer surface of the columnar body, and a hollow cavity is provided inside the columnar body;
[0007] A heating element, provided in the hollow cavity of the columnar body, generates heat after being powered on, and transfers the heat to the columnar body and the sheet structure of the housing.
[0008] In some embodiments, there are multiple sheet structures, and the multiple sheet structures are uniformly arranged along the outer surface of the columnar body.
[0009] In some embodiments, the end of the columnar body is conical.
[0010] In some embodiments, the end face of the sheet structure is an inclined shape, and the included angle between the end face of the sheet structure and the central axis of the housing is half of the conical apex angle of the end of the columnar body.
[0011] In some embodiments, the housing is a ceramic housing or a metal housing.
[0012] In some embodiments, the heating element further includes:
[0013] A filler, provided in the hollow cavity of the columnar body, for fixing the heating element inside the hollow cavity of the columnar body.

[0018] A housing having a mounting seat therein, and the mounting seat accommodates and mounts an aerosol-forming substrate;
[0019] The heating body as described in any one of the above embodiments, the heating body is disposed in the housing, and the columnar body and the sheet-like structure of the outer shell extend into the mounting seat and are used to heat the aerosol-forming substrate.

[0029] Figure 1 And Figure 2 a schematic structural view of a heating element provided by one embodiment of the present application. The heating element is used for a heat-not-burn device. Specifically, the heating element is used for heating an aerosol-forming substrate to cause the aerosol-forming substrate to generate volatiles, thereby forming an aerosol. Please also refer to Figure 1 And Figure 2 , the heating element 100 includes a housing 110 and a heating element 120 disposed inside the housing 110.
[0030] The housing 110 includes a columnar body 111 and a sheet-like structure 112 disposed on the outer surface of the columnar body 111. A hollow cavity 113 is provided inside the columnar body 111.
[0031] The heating element 120 is disposed in the hollow cavity 113 of the columnar body 111. After the heating element 120 is powered on, it generates heat and transfers the heat to the columnar body 111 and the sheet-like structure 112 of the housing 110. In some embodiments, the heating element 120 is a heating wire, and the shape of the heating wire is zigzag, curved or coil-shaped. As needed, the heating element 120 may also be an electromagnetic induction heating element or other types of heating elements.
[0032] In the heating body 100 provided in the above embodiments, the housing 110 is provided to include a columnar body 111 and a sheet-like structure 112 disposed on the outer surface of the columnar body 111, and a hollow cavity 113 is provided inside the columnar body 111 and the heating element 120 is disposed in the hollow cavity 113 of the columnar body 111. When the heating element 120 is powered on to generate heat, the heat is transferred to the columnar body 111 and the sheet-like structure 112 of the housing 110. The structure of the columnar body 111 of the housing 110 can ensure that the heating body 100 has sufficient strength and is not easily broken. The sheet-like structure 112 disposed on the outer surface of the columnar body 111 can provide the heating body 100 with sufficient heating area, thereby improving its atomization effect. On the other hand, disposing the heating element 120 inside the housing 110 can prevent the heating element 120 from directly contacting the aerosol-forming substrate, resulting in too high a local temperature of the heating element 120, and can also prevent damage to the heating element 120 caused by collision with external components.
[0033] In this embodiment, the housing 110 can be used to isolate the heating element 120 and the aerosol-forming substrate, so that the heating element 120 does not directly contact the aerosol-forming substrate. The columnar body 111 of the housing 110 and the sheet-like structure 112 disposed on the outer surface of the columnar body 111 are in direct or indirect contact with the aerosol-forming substrate to transfer the heat generated by the heating element 120 to the aerosol-forming substrate, so that the aerosol-forming substrate generates volatiles. The housing 110 is preferably made of a material with good thermal conductivity to quickly and evenly distribute the heat generated by the heating element 120 on the columnar body 111 and the sheet-like structure 112, so as to uniformly heat the aerosol-forming substrate. In some embodiments, the housing 110 is a ceramic housing or a metal housing. Since metal materials or ceramic materials have good thermal conductivity, they can quickly and evenly distribute the heat generated by the heating element 120 on the columnar body 111 and the sheet-like structure 112, thereby uniformly heating the aerosol-forming substrate.
[0034] In some embodiments, there are multiple sheet-like structures 112. The multiple sheet-like structures 112 are uniformly arranged along the outer surface of the columnar body 111. In this embodiment, there are two sheet-like structures 112. The end face of the sheet-like structure 112 is in an inclined shape so that the sheet-like structure 112 can be better inserted into the aerosol-forming matrix. As needed, the number of the sheet-like structures 112 can also be set to 3, or 4, or more, and the specific number can be determined according to actual needs.
[0035] In some embodiments, the end of the columnar body 111 is conical. The purpose of setting the end of the columnar body 111 to be conical is that during the process of inserting the heating element 100 into the aerosol-forming matrix, the conical structure can enable the columnar body 111 to be better inserted into the interior of the aerosol-forming matrix, thereby making the use process of the aerosol-forming matrix more convenient and smooth. As needed, since the end face of the sheet-like structure 112 is in an inclined shape, at this time, the included angle between the end face of the sheet-like structure 112 and the central axis of the outer shell 110 can be set to half of the conical apex angle of the end of the columnar body 111. At this time, since the end face of the sheet-like structure 112 and the conical surface of the end of the columnar body 111 are substantially in the same plane, this setting method can also enable the heating element 100 to be more effectively inserted into the aerosol-forming matrix.
[0036] In some embodiments, the heating element 100 further includes a filler 130.
[0037] The filler 130 is disposed in the hollow cavity 113 of the columnar body 111 and is used to fix the heating element 120 inside the hollow cavity 113 of the columnar body 111.
[0038] In this embodiment, the heating element 120 is disposed inside the hollow cavity 113 of the columnar body 111 of the housing 110, and then the heating element 120 and the housing 110 are fixed with the filler 130. This way can not only prevent the heating element from contacting with the outside air, moisture, etc. and oxidizing or rusting, but also conveniently fix the heating element 120 and the housing 110 together. In particular, when the heating element 120 is a heating wire, due to problems such as difficulty in inserting and fixing the heating wire, at this time, by disposing the heating wire inside the hollow cavity 113 and using the filler 130 to fix the heating wire and the housing 110 together, the problems of difficulty in inserting the soft heating wire, difficulty in firmly holding it, and difficulty in taking into account the thermal conductivity can be solved. It can be understood that the filler 130 is also preferably made of a material with good thermal conductivity. In some embodiments, the filler 130 includes a ceramic glue solid, a silicone rubber solid or a high-temperature cement solid. Since the ceramic glue solid, the silicone rubber solid or the high-temperature cement solid has good thermal conductivity, it can effectively transfer the heat generated by the heating element 120 to the housing 110, so as to effectively heat the aerosol-forming substrate.
[0039] As needed, the heating element 120 is disposed close to the inner wall of the hollow cavity 113 of the columnar body 111. At this time, the heat generated by the heating element 120 can be more effectively transferred to the housing 110. As needed, the heating element 120 further includes two pins extending outside the columnar body 111 for connecting to an external power supply. In addition, as needed, insulating tubes are provided on the two pins of the heating element 120 to prevent the pins of the heating element 120 from forming electrical contact with other parts.
[0040] Please also refer to Figure 3 and Figure 4 , one embodiment of the present application provides a heat-not-burn device 200. The heat-not-burn device 200 includes a housing 210 and a heating body 100 as described in any one of the above embodiments.
[0041] An installation seat 211 is provided inside the housing 210. The installation seat 211 accommodates and installs the aerosol-forming substrate 300.
[0042] The heating body 100 is disposed inside the housing 210. The columnar body 111 and the sheet-like structure 112 of the housing 110 partially extend into the installation seat 211 and are used to heat the aerosol-forming substrate 300.
[0043] In the heat-not-burn device 200 provided in the above embodiments, the housing 110 is configured to include a columnar body 111 and a sheet-like structure 112 provided on the outer surface of the columnar body 111, and a hollow cavity 113 is provided inside the columnar body 111 and the heating element 120 is provided in the hollow cavity 113 of the columnar body 111. When the heating element 120 is energized to generate heat, the heat is transferred to the columnar body 111 and the sheet-like structure 112 of the housing 110. The structure of the columnar body 111 of the housing 110 can ensure that the heating body 100 has sufficient strength and is not easily broken. The sheet-like structure 112 provided on the outer surface of the columnar body 111 can provide the heating body 100 with sufficient heating area, thereby improving its atomization effect. On the other hand, arranging the heating element 120 inside the housing 110 can prevent the local temperature of the heating element 120 from being too high due to direct contact between the heating element 120 and the aerosol-forming substrate 300, and can also prevent damage to the heating element 120 caused by collision with external components.
[0044] As required, the heat-not-burn device 200 further includes a control board. The heating body 100 is electrically connected to the control board. The control board is used to control the heating body to heat and bake the aerosol-forming substrate.
[0045] For the sake of convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures after inversion. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.
[0046] In addition, it should be noted that using words such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings, and thus cannot be construed as limiting the protection scope of this application.
[0047] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
