[0027] like Figure 1 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 generating matrix. The heating element structure includes a base 1, a support 2, and a heating element 3, as detailed below:
[0028] like Figure 2 As shown, the heating element 3 includes a tube 31 and a heating body 32, which is a needle-type heating element. The heating body 32 is disposed inside the tube 31, and the tube 31 (also called a window) allows infrared light radiated by the heating body 12 to pass through, thereby heating the aerosol generation matrix.
[0029] The tube body 31 is made of a brittle material, which is prone to deformation, cracking, or even breakage when dropped. To solve this problem, such as... Figure 2 As shown, the first end of the tube 31 is open and is disposed inside the base 1. The support 2 is sleeved on the outside of the tube 31 and is at least partially disposed between the tube 31 and the base 1.
[0030] This embodiment adds a support 2 to the outside of the tube 31 of the heating element 3, thereby moving the support point upward and improving the problem that the tube 31 is prone to deformation or cracking when falling.
[0031] During the actual fall, the vertical heating element structure will tilt, and the seat 1 will land. Due to gravity and inertia, the heating element 3 will continue to swing downwards. If there is no support 2, the support point will be at the junction of the heating element 3 and the seat 1. If there is a support 2, the support point will move up to the upper edge of the support 2, thereby shortening the moment arm of the fall.
[0032] In some embodiments, such as Figure 2 As shown, the heating element 3 also includes an insulating support 33, which is at least partially disposed within the tube body 31 and supports the heating body 32. Understandably, at least partially can be partially or entirely.
[0033] In some embodiments, such as Figure 2 As shown, the insulating support 33 has a hollow structure, through which the lead wire 34 can pass. The lead wire 34 is used to realize the electrical connection between the external power supply device and the heating body 32. For example, the insulating support 33 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.
[0034] In some embodiments, such as Figure 2 As shown, the tube body 31 extends out of the support body 2, and the heating body 32 is located within the portion of the tube body 31 that extends out of the support body 2. The heating body 32 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.
[0035] In some embodiments, such as Figure 2 As shown, the heating body 32 can be a spiral heating part 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.
[0036] In some embodiments, such as Figure 2 As shown, the tube body 31 has an opening at the first end along the Z-axis and a pointed structure 311 at the second end. The opening is for the heating body 32 and at least part of the insulating support 33 to pass through the tube body 31, while the pointed structure 311 facilitates the insertion and removal of at least part of the heating body structure into the aerosol generating matrix.
[0037] In some embodiments, the tube 31 is a quartz glass tube. The quartz glass tube mentioned here is only 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.
[0038] In some embodiments, the support 2 is a tube made of a rigid material, or a metal tube, which is sleeved outside the tube 31. The metal here is just an example and is not intended to limit this application. Other materials, such as hard plastic or ceramic, can also be used.
[0039] In some embodiments, such as Figure 2 As shown, the support body 2 extends out of the base body 1, and the height of the part of the support body 2 extending out of the base body 1 is 2mm to 5mm, that is, greater than or equal to 2mm and less than or equal to 5mm. If it is too low, it cannot play a supporting role; if it is too high, it will block the heating body 32, affect the transmission of infrared light, and its own temperature will also be too high, resulting in excessive energy consumption.
[0040] In some embodiments, such as Figure 2 As shown, the support body 2 is partially installed in the seat body 1, and the depth of the part of the support body 2 inserted into the seat body 1 is 2mm to 4mm, that is, greater than or equal to 2mm and less than or equal to 4mm. If it is too low, it will not play a supporting role, and if it is too deep, it will cause the seat body 1 to be too large.
[0041] In some embodiments, the thickness of the support body 2 is 0.05mm to 0.1mm, that is, greater than or equal to 0.05mm and less than or equal to 0.1mm. If the support body 2 is too thin, it will not provide support, and if the support body 2 is too thick, it will make it difficult to insert aerosol to generate the matrix. Therefore, in some embodiments, the end of the support body 2 away from the seat body 1 is provided with a chamfer, so that it is easier to insert aerosol to generate the matrix. For example, the cross-section of the chamfer is an inclined surface that slopes outward in the direction of the seat body 1.
[0042] In some embodiments, such as Figure 2 As shown, the base 1 is a hollow tubular structure used to assemble the heating element structure into the interior of the heated non-combustible aerosol generating device. For example, the base 1 is a flange; the flange here is merely an example and is not intended to limit this application, and other types are also possible.
[0043] In some embodiments, such as Figure 2 and Figure 3As shown, the side wall of the portion of the support 2 inserted into the base 1 has multiple through holes 21. There is a gap between the support 2 and the base 1, which is used to inject an adhesive medium. The adhesive medium is used to fix the tube 31, support 2, and base 1 together. Specifically, the adhesive medium is injected into the gap, and it solidifies at the through holes 21, thus fixing the tube 31, support 2, and base 1 together. For example, the adhesive medium can be glue. However, glue is only an example and is not intended to limit this application; other types of adhesives are also possible.
[0044] Specifically, such as Figure 2 As shown, the base 1 is provided with a hollow mounting groove 11 with steps, the support body 2 is a hollow structure, the first end of the tube 31 and one end of the support body 2 are inserted into the mounting groove 11, the periphery of the opening of the tube 31 and the periphery of the support body 2 abut against the steps, and the insulating support 33 passes through the mounting groove 11, and there is a gap between the inner side wall of the mounting groove 11 and the outer side wall of the support body 2. The gap is used to inject adhesive medium, and the tube 31, the support body 2 and the base 1 are fixed through the adhesive medium. After the adhesive medium solidifies, a fixed body 4 is formed.
[0045] In some embodiments, such as Figure 3 As shown, to achieve a stable fixed connection, multiple through holes 21 are evenly spaced in the circumferential direction of the support body 2. It can be understood that multiple through holes 21 can also be arranged in the axial direction of the support body 2, wherein the axial direction of the support body 2 is the same as the axial direction Z of the tube body 31.
[0046] In some other embodiments, the tube 31 is welded to the support 2, and the support 2 is welded to the base 1. Furthermore, the support 2 is a tube made of a material with a low coefficient of thermal expansion, such as Kovar alloy, which has a lower coefficient of thermal expansion, closer to that of quartz, thereby reducing stress caused by high and low temperatures. The Kovar alloy material mentioned here is merely an example and is not intended to limit this application; other materials with low coefficients of thermal expansion may also be used.
[0047] 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 3 of the heating element structure. The heating element 3 generates infrared light when energized, and heats the contained aerosol generating matrix through the infrared light, causing it to atomize and generate aerosol. The atomization stability is good and the atomized taste is excellent.
[0048] 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.
[0049] By implementing this utility model, the following beneficial effects can be achieved:
[0050] This embodiment adds a support 2 to the outside of the tube 31 of the heating element 3, thereby moving the support point upward and improving the problem that the tube 31 is prone to deformation or cracking when falling.
[0051] 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. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this utility model, and can also make several modifications and improvements, all of which fall within the protection scope of this utility model. That is, the embodiments described "in some embodiments" can be freely combined with any of the preceding and following embodiments. Therefore, all equivalent transformations and modifications made within the scope of the claims of this utility model should fall within the coverage of the claims of this utility model.
