[0025] Figure 1 Some preferred embodiments of the aerosol generating device of this utility model are shown. The aerosol generating device can heat the aerosol generating matrix by heating without combustion. In some embodiments, the aerosol generating matrix can be columnar, and can be a solid material made of plant (e.g., tobacco) leaves and / or stems in the form of strips, granules, flakes, or integral molding, and aroma components can be further added to the solid material.

[0026] In some embodiments, the aerosol generating device may include a heating element 1 and a power supply element (not shown). The heating element 1 may be at least partially inserted into the aerosol generating matrix and heat the aerosol generating matrix by radiating infrared light, thereby causing the aerosol generating matrix to generate aerosols for the user to inhale. The power supply element (not shown) is connected to the heating element to supply power to the heating element.

[0027] like Figure 1 As shown, in some embodiments, the heating component 1 may include a heating structure 10 and a mounting base 20. The heating structure 10 may be mounted on the mounting base 20, and may be generally columnar, partially inserted into the aerosol generating matrix and heated by radiating infrared light. The mounting base 20 serves to support and fix the heating structure 10.

[0028] In some embodiments, the heating structure 10 may include a tube 11 that transmits infrared light waves. In some embodiments, the tube 11 may be a quartz glass tube. Of course, it is understood that in other embodiments, the tube 11 is not limited to an infrared-transmitting quartz tube, but may be other window materials that allow infrared light waves to pass through, such as transparent ceramics, diamond, etc.

[0029] In some embodiments, the tube 11 may be cylindrical with a generally circular cross-section. The tube 11 may include a cylindrical body 111 and a pointed tip 113, and one end of the tube 11 has an opening 112. Specifically, the cylindrical body 111 may be cylindrical and hollow. The opening 112 may be provided at one end of the cylindrical body 111. It is understood that in some other embodiments, the cylindrical body 111 is not limited to a cylindrical shape, but may be cuboid, flat, or other shapes. The pointed tip 113 is located at the end of the cylindrical body 111 away from the opening 112. The pointed tip 113 facilitates at least a portion of the heating structure 10 being inserted into and removed from the aerosol generating matrix. The pointed tip 113 may be conical or arc-shaped. In some embodiments, a cavity 114 is formed inside the tube 11. This cavity 114 is a cylindrical cavity and may be non-sealed. Specifically, the cavity 114 may communicate with the opening 112.

[0030] In some embodiments, the heating structure 10 further includes a heating element 12, which is at least partially disposed in the tube body 11. Specifically, the heating element 12 can penetrate the tube body 11 from the opening 112 and can be partially located in the cavity 114. The heating element 12 is used to generate heat and radiate infrared light, which passes through the tube wall of the tube body 11 and enters the aerosol generating matrix.

[0031] In some embodiments, the heating element 12 may include a heating portion 121 and a support body 122. In some embodiments, the heating portion 121 is at least partially disposed on the outer periphery of the support body 122; specifically, the heating portion 121 may be disposed around the outer periphery of the support body 122. The heating portion 121 may be spaced apart from a portion of the inner wall of the tube 11, thereby facilitating rapid heating without scorching and preventing the heating portion 121 from overheating and adversely affecting the tube 11. The support body 122 may be located at the central axis of the heating portion 121. The support body 122 serves to support the heating portion 121.

[0032] In some embodiments, the heating element 121 can be formed by bending or winding a longitudinally elongated heating body 1211 around the outer periphery of the support 122. The heating element 121 may be generally spiral-shaped. Of course, it is understood that in some other embodiments, the heating element 121 is not limited to a spiral shape, and may also be columnar or cylindrical with a hollow structure. In some embodiments, the heating body 1211 forming the heating element 121 is a heating body capable of radiating infrared light waves, which may include a heating substrate and a heat radiation layer disposed on the heating substrate. The heating substrate can generate heat when energized. The heating substrate can be a metal cylinder or a metal wire, and can be a metallic material with good high-temperature oxidation resistance, high stability, and non-deformation properties, such as nickel-chromium alloy (e.g., nickel-chromium alloy wire) or iron-chromium-aluminum alloy (e.g., iron-chromium-aluminum alloy wire). The heat radiation layer can be an infrared layer. The infrared layer can be formed on the heating substrate by an infrared layer forming substrate under high-temperature heat treatment, and can radiate infrared light. The infrared layer forming substrate can be silicon carbide, spinel, or a composite substrate thereof. Understandably, in some other embodiments, the thermal radiation layer is not limited to an infrared layer. In some other embodiments, the thermal radiation layer may be a composite infrared layer.

[0033] In some embodiments, the end of the heating element 121 away from the port 112 can be connected to the support body 122. Further, the end of the heating element 121 away from the port 112 can be mechanically and electrically connected to the support body 122. Specifically, the end of the heating element 121 away from the port 112 can be connected to the end of the support body 122 facing the tip 113, or to a section of the sidewall of the support body 122 near the tip 113. The heating element 121 and the support body 122 can be fixed together by welding, forming an integral structure for easy assembly.

[0034] In some other embodiments, the heating element 121 and the support 122 may also be integrally formed, and a heating element 1211 may be bent to form it.

[0035] In some embodiments, the support 122 may be generally columnar, and the rigidity of the support 122 may be greater than that of the heating element 1211, thereby serving to support the heating element 121.

[0036] In some embodiments, the heating structure 10 further includes a fixing member 13, which is at least partially installed in the tube body 11 from the opening 112. Specifically, the fixing member 13 may be columnar and may be longitudinally arranged along the length direction of the tube body 11. The fixing member 13 may be coaxially arranged with the tube body 11, and its axial length is less than the length of the tube body 11. One end of the fixing member 13 may be spaced apart from the tip 113 of the tube body 11, and the length of the gap is greater than the axial length of the heating portion 121 of the heating element 12. The other end of the fixing member 13 may protrude from the opening 112 or be flush with the opening 112. In some embodiments, the outer wall of the fixing member 13 may be fitted with the inner wall of the tube body 11 without clearance; specifically, the fixing member 13 may be fixed to the tube body 11 by an interference fit. In other embodiments, the fixing member 13 may also be bonded to the inner wall of the tube body 11 by an adhesive structure. In some embodiments, the fixing member 13 may be an insulating tube, such as a ceramic tube, a quartz tube, or a high-temperature resistant plastic tube.

[0037] In some embodiments, the fixing member 13 has a fixing hole 131, which is provided through the fixing member 13 along its axial direction. The fixing hole 131 is coaxial with the tube body 11. The fixing hole 131 can be used to install and fix the support body 122 of the heating element 12. Generally, the support body 122 can be partially inserted into the fixing hole 131 and tightly fitted with the fixing hole 131, so that the heating element 12 can be fixed in the tube body 11, thereby improving the stability of the heating element 12. This reduces the deformation and movement of the heating element 12 when the aerosol generating device is dropped, thereby reducing the impact of the heating element 12 on the tube body 11 and improving the drop deformation of the heating assembly.

[0038] In some embodiments, the heating structure 10 further includes two conductive connectors 14, one of which can be connected to the support 122 and the other to the heating element 121. Both conductive connectors 14 can partially extend from the fixing member 13 out of the tube 11 to connect with the power supply assembly. Specifically, one conductive connector 14 can be welded to one end of the support 122 inserted into the fixing hole 131 and extends through the fixing hole 131. The other conductive connector 14 can be welded to one end of the heating element 121 facing the tube opening 11 and extends axially along the fixing member 13. The fixing member 13 may have a lead wire hole for the conductive connector 14 to pass through. In some embodiments, the conductive connector 14 can be a conductive needle or a conductive post. In other embodiments, the conductive connector 14 can also be a lead wire.

[0039] like Figure 1 and Figure 2As shown, in some embodiments, the mounting base 20 may be cylindrical, specifically, it may be a cylindrical structure with a circular cross-section and a hollow inner side. In some embodiments, the mounting base 20 may include an end wall 21 and an annular wall 22 disposed on the outer periphery of the end wall 21. The mounting base 20 also includes an opening 24 at one end opposite to the end wall 21. A mounting post 23 extending toward the opening 24 is disposed on the inner side of the end wall 21, and the mounting post 23 can be used for the insertion and fixing of the heating structure 10. Specifically, in this embodiment, a mounting hole 231 is provided on the end wall 21, and the mounting hole 231 may be formed in the mounting post 23, which can extend from the end wall 21 to the end of the mounting post 23 away from the end wall 21. The mounting hole 231 can be used for the insertion and installation of the heating structure 10. In this embodiment, the tube body 11 of the heating structure 10 is inserted into the mounting hole 231, and a gap is left between the two, which can be fixed by providing a first adhesive structure 40. A second adhesive structure 50 can be provided at the end of the mounting hole 231 away from the end wall 21 to bond and fix the tube body 11 to the mounting post 23. In some other embodiments, the tube body 11 of the heating structure 10 is inserted into the mounting hole 231 and can be fixed with the mounting hole 231 by interference fit.

[0040] In some embodiments, the end wall 21 and the annular wall 22 connect and define a cavity 25, which may be an annular cavity formed between the mounting post 23 and the annular wall 22. The cavity 25 may communicate with the opening 24, which can be used for mounting the damping structure 30. In some embodiments, the depth of the cavity 25 may be 2-8 mm. Choosing a cavity 25 with this depth is more conducive to the damping structure 30 achieving its damping effect.

[0041] In some embodiments, the heating component 1 further includes a shock-absorbing structure 30 disposed in the cavity 25 and tightly fitted with the mounting base 20. The shock-absorbing structure 30 may be located on the outer periphery of a portion of the heating structure 10. Specifically, the shock-absorbing structure 30 may be formed on the outer periphery of the mounting post 23 and at least partially fits without clearance with the annular wall 22 and the outer wall of the mounting post 23. This allows it to be located on the outer periphery of the tube 11 of the heating structure 10. During the drop of the aerosol generating device, the shock-absorbing structure 30 can reduce the impact energy transmitted to the tube 11, thereby preventing the heating structure 10 from deforming or breaking upon impact. By tightly fitting the shock-absorbing structure 30 with the mounting base 20, detachment of the shock-absorbing structure 30 can be prevented. By ensuring a gapless fit between the shock-absorbing structure 30 and the outer wall of the annular wall 22 and the mounting post 23, the stability of the shock-absorbing structure 30 installation can be improved, while simultaneously enhancing the shock absorption effect.

[0042] In some embodiments, the shape of the damping structure 30 may be adapted to the shape of the cavity 25. The axial dimension of the damping structure 30 may be greater than or equal to the depth of the cavity 25. The damping structure 30 may be partially or completely housed within the cavity 25 and may fill the cavity 25, thereby greatly improving the damping effect. In some embodiments, the thickness of the damping structure 30 may be 1-3 mm.

[0043] In some embodiments, the damping structure 30 may be integrally formed with the mounting base 20. The damping structure 30 may be formed by a colloidal filler filled in the cavity 25. In some embodiments, the colloidal filler may be a soft gel, such as silicone. In some embodiments, the colloidal filler may be a solid colloid that can be directly filled into the cavity 25. In other embodiments, the colloidal filler may also be a liquid colloid that can solidify after being filled into the cavity 25 to form the damping structure 30. Specifically, in some embodiments, the colloidal filler may be filled into the cavity 25 by at least one of the following filling methods: dispensing, foaming, injection (e.g., secondary injection filling in a mold), and molded part assembly filling. The colloidal filler may also be a fluid inorganic mixture solidified.

[0044] In some other embodiments, the damping structure 30 and the mounting base 20 can be separate structures, with the damping structure 30 detachably assembled to the mounting base 20. Specifically, the damping structure 30 can be generally annular, at least partially embedded in the cavity 25, and fitted around the outer periphery of the mounting post 23, and at least partially interference-fitted with the mounting base 20, thereby preventing it from falling off after assembly. In some other embodiments, the opening 24 can also be provided with a sealing structure to press the damping structure 30 into the cavity 25, preventing the damping structure 30 from falling off and increasing the damping effect.
