[0033] like Figure 1 and Figure 2 As shown, some embodiments of this utility model disclose a heating element structure applied in a device for heating non-combustible aerosols to heat the aerosol generation matrix. The heating element structure includes a heating element 1, a flange shell 2, an energy-absorbing component 3, and a first energy-absorbing element 4, as detailed below:

[0034] like Figure 3As shown, the heating element 1 includes a tube 11 and a heating body 12, that is, the heating element 1 is a needle-type heating element. The heating body 12 is located inside the tube 11, and the tube 11 (also called a window) allows infrared light radiated by the heating body 12 to pass through, thereby heating the aerosol generation matrix.

[0035] The tube body 11 is made of a brittle material that is prone to deformation, cracking, or even breakage. For example, the tube body 11 is a quartz glass tube. The quartz glass tube mentioned here is just an example and is not intended to limit this application. It can also be other window materials that allow infrared light to pass through, such as transparent ceramic tubes.

[0036] To address the issue of easy cracking in pipe body 11, such as Figure 3 As shown, the flange housing 2 surrounds part of the pipe body 11, the energy-absorbing assembly 3 is disposed between the flange housing 2 and the pipe body 11, and the first energy-absorbing element 4 is disposed on the outer side wall of the flange housing 2. It should be noted that the extension direction of the side wall described throughout the text is the same as the axial direction Z of the pipe body 11.

[0037] This embodiment adds a flange shell 2, an energy-absorbing component 3, and a first energy-absorbing element 4 to the outside of the pipe body 11, thereby absorbing external impact energy such as when it falls to the ground, reducing the impact energy transmitted to the pipe body 11, and improving the problem of deformation or cracking of the pipe body 11 when it falls.

[0038] Furthermore, along the axial Z-axis of the tube body 11, the flange shell 2, the energy-absorbing component 3, and the first energy-absorbing element 4 are respectively arranged at intervals or adjacent to the heating body 12, so as not to block the transmission of infrared light. At the same time, since the temperature at the heating body 12 is high, the components can be prevented from melting.

[0039] In some embodiments, such as Figure 3 As shown, the heating element 1 also includes an insulating support 13, which is at least partially located inside the tube 11 and supports the heating body 12. The heating body 12 includes a heating substrate and an infrared radiation layer disposed on the outer surface of the heating substrate. When the heating substrate is electrically heated, it can excite the infrared radiation layer to generate infrared light and radiate it.

[0040] In some embodiments, such as Figure 3 As shown, the heating body 12 can be a spiral heating element made of nickel-chromium-aluminum alloy material. The nickel-chromium-aluminum alloy material and spiral shape are only examples and are not intended to limit this application. Other materials and other shapes are also possible, such as iron-chromium-aluminum alloy material, single spiral or double spiral, etc.

[0041] In some embodiments, such as Figure 3As shown, the insulating support 13 has a hollow structure, through which the lead wire 14 can pass. The lead wire 14 is used to realize the electrical connection between the external power supply device and the heating body 12. For example, the insulating support 13 is a hollow tubular ceramic body. The tubular ceramic body here is only an example and is not intended to limit this application. It can also be other shapes or other insulating materials, such as quartz glass.

[0042] In some embodiments, such as Figure 3 As shown, one end of the tube body 11 along the Z-axis has an opening, and the other end has a pointed structure 111. The opening is for the heating body 12 and at least part of the insulating support 13 to pass through the tube body 11, while the pointed structure 111 facilitates the insertion and removal of at least part of the heating body structure into the aerosol generating matrix.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the heating element structure also includes a flange 5, which is a hollow ring and surrounds part of the outer wall of the tube 11. Furthermore, along the axial direction Z of the tube 11, the flange 5 is spaced apart from or adjacent to the heating body 12. An energy-absorbing assembly 3 is mounted on the flange 5, and the flange housing 2 surrounds the energy-absorbing assembly 3.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the energy-absorbing assembly 3 includes a second energy-absorbing element 31 and a third energy-absorbing element 32. The second energy-absorbing element 31 is provided on the flange 5 near the end of the heating body 12. The second energy-absorbing element 31 is hollow columnar and surrounds the outer wall of the tube body 11. The second energy-absorbing element 31 is provided with a mounting groove, and the flange 5 is at least partially embedded in the mounting groove.

[0045] A third energy-absorbing element 32 is provided at the end of the flange 5 away from the heating body 12. The third energy-absorbing element 32 is hollow and annular, and is arranged around the outer wall of the tube body 11.

[0046] In some embodiments, the first energy-absorbing element 4, the second energy-absorbing element 31, and the third energy-absorbing element 32 are elastomers, such as soft rubber. The soft rubber mentioned here is only an example and is not intended to limit this application. Other elastic materials may also be used.

[0047] In some embodiments, such as Figure 3 As shown, the contact height between the second energy-absorbing element 31 and the outer wall of the tube body 11 is 2mm to 5mm, that is, greater than or equal to 2mm and less than or equal to 5mm. If the contact height is too small, the second energy-absorbing element 31 will not be supported enough. If the contact height is too large, the size will be too large. In addition, the temperature at the heating body 12 is high, which will increase the risk of the second energy-absorbing element 31 melting.

[0048] In some embodiments, such as Figure 3As shown, the interference between the second energy-absorbing component 31 and the outer wall of the tube body 11 is 15% to 30%, that is, greater than or equal to 15% and less than or equal to 30%. If the interference is too small, the second energy-absorbing component 31 will not be supported enough and the tube body 11 will sway left and right. If the interference is too large, it will cause assembly difficulties.

[0049] In some embodiments, such as Figure 3 As shown, the flange housing 2 surrounds the outer wall of the second energy-absorbing element 31. Specifically, the flange housing 2 is a hollow column. When the flange 5, the second energy-absorbing element 31, and the third energy-absorbing element 32 are installed on the heating element 1, the flange housing 2 allows the heating element 1 to pass through and be fitted onto the outer wall of the second energy-absorbing element 31. Its outer wall includes the end face of the second energy-absorbing element 31 near the heating body 12 and the outer side wall.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the heating element structure also includes a cover 6. The cover 6 is detachably connected to one end of the flange housing 2 away from the heating body 12. The cover 6 is installed by fitting the flange housing 2 to fix the third energy-absorbing element 32 and the flange 5.

[0051] In some embodiments, to prevent aging of the second energy-absorbing element 31 and corrosion by the liquid medium during use, such as Figure 4 As shown, the heating element structure also includes a protective component 7, which is a hollow ring. The protective component 7 is provided at one end of the second energy-absorbing component 31 near the heating body 12, and is arranged around the outer wall of the tube body 11. In the axial direction Z of the tube body 11, the protective component 7 is arranged at intervals or adjacent to the heating body 12.

[0052] Furthermore, the protective element 7 covers one end face of the second energy-absorbing element 31 near the heating body 12. Alternatively, the protective element 7 and the flange housing 2 together cover one end face of the second energy-absorbing element 31 near the heating body 12.

[0053] In some embodiments, the protective component 7 is a corrosion-resistant elastomer formed by filling the space between the inner wall of the flange housing 2 and the outer wall of the pipe body 11 with adhesive, such as resin adhesive. The protective component 7 and the second energy-absorbing component 31 are fitted together to prevent the second energy-absorbing component 31 from aging and being corroded by the liquid medium during use.

[0054] In some embodiments, such as Figure 2 As shown, in order to better absorb impact energy, at least one buffer flange 41 is provided on the outer side wall of the first energy-absorbing member 4. Understandably, at least one flange can be one, two, three or any number of flanges.

[0055] Some embodiments of this utility model also disclose an aerosol generating device, specifically a heated non-combustible aerosol generating device, including the heating element structure and power supply device described in any of the above embodiments. The power supply device supplies power to the heating element structure. When the heating element structure is energized, it heats the contained aerosol generating matrix with infrared light, resulting in good atomization stability and excellent atomized taste.

[0056] The aerosol generating matrix is ​​removably housed in the heated non-combustible aerosol generating device. The aerosol generating matrix can be a columnar aerosol generating product, specifically a solid material made from plant leaves and / or stems, and aroma components can be further added to the solid material. Understandably, in some other embodiments, the aerosol generating matrix can be a sheet-like or cylindrical aerosol generating product, and this is not limited thereto.

[0057] By implementing this utility model, the following beneficial effects can be achieved:

[0058] This invention absorbs external impact energy, such as when the pipe body 11 falls to the ground, by adding a flange shell 2, an energy-absorbing component 3 and a first energy-absorbing element 4 to the outside of the pipe body 11, thereby reducing the impact energy transmitted to the pipe body 11 and improving the problem of deformation or cracking of the pipe body 11 when it falls.

[0059] It is understood that the above embodiments only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
