Description

[Technical Field]

[0001] The present invention relates to the field of atomization, and more particularly to aerosol generators, heat-generating components, and heat-generating structures. [Background technology]

[0002] In the field of heated non-combustion atomization, the aerosol generating substrate is generally heated using methods such as a central heating structure or a peripheral heating structure. The heating structure in related technologies usually includes a housing and a heating element, and the heating element is generally mounted directly inside the casing. After being energized, the heating element generates synchrotron radiation, which penetrates the casing and heats the aerosol generating substrate. The role of the casing is to isolate the heating element and allow the synchrotron radiation waves to pass through. In conventional technology, mounting this heating element inside the housing is difficult and easily leads to unstable mounting of the heating element. This affects the temperature field distribution of the entire heating element, resulting in uneven flavor when inhaled. Therefore, the current challenge is how to stably mount the heating element inside the housing. [Overview of the Initiative]

Explanation of reference numerals in the drawing [Modes for carrying out the invention]

[0029] Figures 1 and 2 show a first embodiment of the aerosol generator of the present invention. This aerosol generator 100 heats the aerosol generating substrate 200 using a non-combustion heating method, resulting in high atomization stability and excellent flavor during atomization. In this embodiment, the aerosol generating substrate 200 is installed in the aerosol generator 100 in a removable manner, and the aerosol generating substrate 200 can be cylindrical. Specifically, the aerosol generating substrate can be a solid material such as a thread-like, sheet-like, or integrally molded form made from the leaves and / or stems of a plant (e.g., tobacco), and flavoring components can also be added to this solid material.

[0030] As shown in Figures 1 and 2, in this embodiment, the aerosol generator 100 includes a heating component 10, a power supply component 20, and a casing 30. The heating component 10 is partially inserted into the aerosol generating substrate 200, specifically, a portion thereof is inserted into the medium portion of the aerosol generating substrate 200, and emits infrared light waves when energized, heating and atomizing the medium portion of the aerosol generating substrate 200 to generate an aerosol. The heating component 10 has the advantages of being easy to install, having a simple structure, high atomization efficiency, excellent consistency and stability, and a long lifespan. The power supply component 20 is used to supply power to the heating component 10. The casing 30 houses the power supply component 20 and can be attached to the heating component 10. In this embodiment, the aerosol generator 100 includes an extractor 40, which can be attached to the heating component 10 and is used to house the aerosol generating substrate 200.

[0031] As shown in Figures 3 to 8, in this embodiment, the heating component 10 further includes a heating structure 11 and a bracket 12. The heating structure 11 is mounted on the bracket 12 and at least a portion of it is insertable into the aerosol generating substrate 200, and heats the aerosol generating substrate 200 by emitting infrared light waves. The heating structure 11 is insertable along the axial direction of the aerosol generating substrate 200 and can be positioned along the central axis of the aerosol generating substrate 200. As can be understood, in other embodiments, the heating structure 11 may be mounted on the outer circumference of the aerosol generating substrate 200 and radiate infrared light waves toward the aerosol generating substrate 200. The bracket 12 is used to mount and fix the entire heating structure 11 and serves to support the heating structure 11. In this embodiment, the bracket 12 can be omitted.

[0032] In this embodiment, the heating structure 11 includes a tube 111 and a heating element 112. In this embodiment, the tube 111 is installed so as to cover at least a portion of the heating element 112, and can transmit light waves to the aerosol generating substrate 200. Specifically, in this embodiment, the tube 111 can transmit infrared light waves, thereby facilitating the emission of infrared light waves from the heating element 112 and heating the aerosol generating substrate 200. In this embodiment, a portion of the heating element 112 is installed inside the tube 111 and used to emit infrared light waves, which penetrate the tube 111 and enter the aerosol generating substrate 200. When energized, the heating element 112 can rapidly heat up to approximately 1000°C in 1 to 3 seconds, while the surface temperature of the tube 111 is controlled to approximately 350°C, and the atomization temperature of the aerosol generating substrate 200 is controlled to 300 to 350°C. This enables accurate atomization of the aerosol-generating substrate 200 in the 2-4.75 μm wavelength band and the 8-11 μm wavelength band. The maximum operating temperature of the heating element 112 of the present invention is 500-1300°C, which far exceeds the maximum operating temperature of conventional heating elements. In this embodiment, the tube is a tube with a circular cross-sectional shape at any position (in other embodiments, the tube may be a flat plate, a triangular prism, or other shape). The above-mentioned heating rate can be adjusted according to the user's habits or other requirements. For example, by raising the temperature to approximately 1000°C in 1-3 seconds, the requirement that a cigarette can be inserted and inhaled immediately is met, eliminating the need to preheat for about 15 seconds as in the conventional technology. In some embodiments, the surface temperature of the tube 111 can reach 550°C during the preheating process, which is the local maximum temperature of the tube 111 and has a relatively short duration. Due to its small heat capacity, it cools down quickly, and the aerosol-generating substrate is not scorched.

[0033] In this embodiment, the tube 111 may be a quartz glass tube. Of course, as can be seen, in other embodiments, the tube 111 is not limited to an infrared-transmitting quartz tube, but may be a light-wave-transmitting window material such as transparent ceramics or diamond.

[0034] In this embodiment, the tube 111 has a hollow structure, and specifically, in this embodiment, the cross-section of the tube 111 can be substantially circular. Of course, as can be understood, in other embodiments, the cross-section of the tube 111 is not limited to circular, but may be, for example, elliptical, square, or triangular prism-shaped. In this embodiment, the tube 111 includes a columnar body 111a and a tip 111b, the columnar body 111a can be cylindrical and installed hollow. As can be understood, in other embodiments, the columnar body 111a is not limited to cylindrical, but may be rectangular or other shapes. The tip 111b is installed at one end of the columnar body 111a, and by installing the tip 111b, at least a part of the heating structure 11 can be easily inserted into and removed from the aerosol generating substrate 200. At least a part of the heating structure 11 can be easily inserted into and removed from the aerosol generating substrate 200. The tip 111b may be conical. In this embodiment, a cavity body 1110 is formed inside the tube body 111, and the cavity body 1110 is a columnar cavity body and can be installed in an unsealed manner. When the heating element 112 is installed inside it, the cavity body 1110 does not require vacuuming or inert gas filling. In this embodiment, the tube body 111 has a tube opening 1111, which is installed at one end away from the tip 111b of the columnar body 111a and communicates with the cavity body 1110, and is used to insert the heating element 112 into the cavity body 1110.

[0035] In this embodiment, the heating element 112 may include a heating section 1121, two conductive sections 1122, and two connecting sections 1123. In this embodiment, the heating section 1121 is installed inside the tube 111 and at least partially spaced apart from the tube wall of the tube 111, and is capable of emitting infrared light waves when energized, which penetrate the tube 111 and reach the aerosol generating substrate 200. Specifically, in this embodiment, the heating section 1121 as a whole does not come into contact with the tube wall of the columnar body 111a, that is, its entirety is installed at a distance from the tube wall of the columnar body 111a. Each conductive section 1122 is connected to one connecting section 1123 and connected to the heating section 1121 via the connecting section 1123. The two conductive sections 1122 are spaced apart and are either independent of or insulated from each other. Both conductive parts 1122 are drawn out from the tube 111 and can be electrically connected to the power supply component 20. Each connection part 1123 is installed corresponding to one conductive part 1122, located at one end of the conductive part 1122 closest to the heating element 1121, and is used to connect the conductive part 1122 and the heating element 1121.

[0036] In this embodiment, the heating element 1121 can be substantially columnar, and more specifically, it can be a spiral columnar. As can be understood, in other embodiments, the heating element 1121 is not limited to a spiral columnar shape, and in other embodiments, the heating element 1121 may be a vertically elongated sheet, or it may have an M-shaped structure, an N-shaped structure, or other shapes. The heating element 1121 can be formed by winding at least one vertically elongated heating element 1120. Specifically, in this embodiment, there may be one heating element 1120, which can be formed by bending both ends and then winding it in a single-helix or double-helix winding manner. In this embodiment, there may be multiple heating elements 1120. By connecting one end of multiple heating elements 1120 and winding them together, a heating element 1121 with a single-helix structure, a double-helix structure, an M-shaped structure, an N-shaped structure, etc., can be formed. The heating element here may be a metal wire.

[0037] In this embodiment, one end of the heating element 1121 away from the conductive element 1122 is press-fitted with or overlapped with a portion of the inner wall of the tip 111b. That is, a limiting effect can be achieved between the end of the heating element 1121 away from the conductive element 1122 and the tip 111b, thereby fixing the heating element 1121 to the pipe body 111 and maintaining a distance from the pipe wall of the columnar body 111a.

[0038] In this embodiment, the heating element 1120 is provided in an elongated shape and its cross-section can be generally circular. Of course, as can be understood, in other embodiments, the cross-section of the heating element 1120 is not limited to circular, but may be square or other shapes. In this embodiment, the heating element 1120 may include a heating substrate and a heat radiation layer provided on the heating substrate. The heating substrate can generate heat when energized, and the heating substrate can be a normal heating wire or heating sheet, specifically a metal wire, and can be selected from metallic materials that have good oxidation resistance at high temperatures, high stability, and resistance to deformation, such as nickel-chromium alloy (e.g., nickel-chromium alloy wire) and iron-chromium-aluminum alloy (e.g., iron-chromium-aluminum alloy wire). The heat radiation layer can be an infrared layer. The infrared layer is formed on the heating substrate by an infrared layer-forming substrate under high-temperature heat treatment, and can emit infrared light waves. Here, the infrared layer-forming substrate can be silicon carbide, spinel, or a composite substrate thereof. As can be understood, in other embodiments, the heat radiation layer is not limited to an infrared layer. In other embodiments, the thermal radiation layer may be a composite infrared layer. In this embodiment, the heating element 1120 may further include an oxidation-resistant layer formed between the heating substrate and the thermal radiation layer. In this embodiment, the heating substrate undergoes high-temperature heat treatment to form a dense oxide film on its surface, and this oxide film can form an oxidation-resistant layer.

[0039] In this embodiment, two conductive parts 1122 are provided at one end of the heating element 1121, and each conductive part 1122 can be connected to one end of the heating element 1120. The two conductive parts 1122 are insulated from each other. Each conductive part 1122 can be provided by extending it from the pipe opening 1111, and one section of each conductive part 1122 extending from the pipe opening 1111 is bent. In this embodiment, the conductive part 1122 is provided in a vertically elongated shape, and the conductive part 1122 can be a lead wire. Of course, as can be understood, in other embodiments, the conductive part 1122 is not limited to a lead wire, but can be a conductive sheet, a conductive contact pin, or other conductive structure. In this embodiment, the conductive part 1122 and the heating element 1121 can be formed as a single unit by welding. As can be understood, in other embodiments, the conductive part 1122 is not limited to connection with the heating element 1121 by welding, but can also be connected by a plug connection or other method. By fixing the conductive part 1122 and the heating part 1121, and by leading the two conductive parts 1122 from the same end of the heating part 1121, the installation of the heating element 112 can be facilitated. In this embodiment, the power supply component 20 includes two electrodes, and each conductive part 1122 can be electrically connected to one electrode. In this embodiment, the conductive part 1122 can be directly welded to the electrode. In other embodiments, the conductive part 1122 can also be electrically connected to the electrode by contact. For example, one end of the conductive part 1122 can be connected to or form a first contact, and the electrode can be provided with a second contact, so that when assembling the heating component 10 and the power supply component 20, the first contact and the second contact can be in contact and electrically connected. By employing contact connections, the detachable assembly of the heating component 10 and the power supply component 20 can be facilitated.

[0040] In this embodiment, the connecting portion 1123 can form an integral structure with the conductive portion 1122 and the heating portion 1121. Specifically, in this embodiment, the connecting portion 1123 can be a welding point. In other embodiments, the connecting portion 1123 is not limited to a welding point and can be a connecting sleeve or other connecting structure. In this embodiment, the cross-sectional area of ​​the connecting portion 1123 can be larger than the cross-sectional area of ​​the conductive portion 1122, thereby facilitating the positioning and mounting of the heating element 112. Specifically, the cross-section of the connecting portion 1123 can be generally circular, and as can be understood, in other embodiments, the cross-section of the connecting portion 1123 is not limited to a circular shape and can be square, elliptical, or other shapes. In this embodiment, the cross-sectional area of ​​the connecting portion 1123 is 0.07 mm². 2 ~0.8mm 2 (Endpoint value 0.07 mm) 2 , 0.8mm 2 (including any value between 0.2 mm and 1.5 mm); in this embodiment, the width of the cross-section of the connecting portion 1123 can be 0.2 mm to 1.5 mm (including endpoint values ​​of 0.2 mm, 1.5 mm and any value between 0.2 mm and 1.5 mm), and furthermore, the cross-section of the connecting portion 1123 can be circular, and its diameter is 0.2 mm to 1.5 mm (including endpoint values ​​of 0.2 mm, 1.5 mm and any value between 0.2 mm and 1.5 mm).

[0041] In other embodiments, the connecting portion 1123 can be omitted. The cross-sectional dimension of one end of the conductive portion 1122 closer to the heat-generating portion 1121 can be larger than the cross-sectional dimension of the other end further away from the heat-generating portion 1121, and in this embodiment, the conductive portion 1122 can be conical. Alternatively, the cross-sectional dimension of one end of the heat-generating portion 1121 closer to the conductive portion 1122 can be larger than the cross-sectional dimension of the conductive portion 1122.

[0042] In this embodiment, the heating structure 11 further includes a mounting member 113, which is attached to one end of the pipe body 111 having a pipe opening 1111. At least a portion of the mounting member 113 is inserted into the pipe body 111, and the two are fixed together by press-fitting. The press-fitting here may be achieved by direct contact between the mounting member 113 and the pipe body 111, by applying an adhesive between them, or by sandwiching a conductive part 1122 between them to achieve press-fitting between the mounting member 113 and the pipe body 111. Specifically, a portion of the mounting member 113 is located in the pipe body 111, and a portion is installed penetrating from the pipe opening 1111. In other embodiments, the mounting member 113 is not limited to being located inside the pipe body 111 and installed coaxially with the pipe body 111, but may also be located outside the pipe opening 1111. The conductive portion 1122 is installed through the mounting member 113 and connected to the heating portion 1121, thereby fixing the heating element 112 to the mounting member 113. By press-fitting the mounting member 113 into the pipe wall of the pipe body 111, the heating portion 1121 can be well positioned in the center within the pipe body 111, and a certain degree of verticality can be maintained. In this embodiment, the mounting member 113 is an insulating member, and the mounting member 113 can separate the two conductive portions 1122 and is used to provide the two conductive portions 1122 in an insulated manner. Of course, as can be understood, in other embodiments, the mounting member 113 is not limited to an insulating member, and the mounting member 113 may be a metal member, and an insulating structure may be provided on the surface that contacts the conductive portion 1122, for example, an insulating sleeve attached to the conductive portion 1122 may be fitted into the mounting member 113, or an insulating layer may be provided on the surface that contacts the conductive portion 1122. In other embodiments, insulating installation from the mounting member 113 can be achieved by installing an insulating layer on the outer surface of the conductive part 1122, thereby achieving insulating installation of the two conductive parts 1122. In this embodiment, the mounting member 113 serves to fix the heating element 112. In this embodiment, the mounting member 113 is fixed inside the pipe body 111, and specifically, the pipe wall of the portion of the mounting member 113 located inside the pipe body 111 is fixed to the inner wall of the pipe body 111 by applying adhesive, thereby preventing the movement of the mounting member 113.Of course, as can be understood, in other embodiments, the mounting member 113 is not limited to being fixed by adhesive, but can also be pressed by, for example, the base 13 on the bracket 12.

[0043] In this embodiment, the mounting member 113 is columnar, and its cross-sectional shape may be the same as the cross-sectional shape of the cavity body 1110 of the pipe body 111, and the cross-sectional area of ​​the mounting member 113 matches the cross-sectional area of ​​the cavity body 1110 of the pipe body 111. In this embodiment, the difference between the cross-sectional width of the mounting member 113 and the cross-sectional width of the pipe body 111 can be 0.01 mm to 0.3 mm (including endpoint values ​​of 0.01 mm, 0.3 mm, and any intermediate value), thereby allowing the mounting member 113 to be smoothly inserted into the pipe body 111 and ensuring a limit. Specifically, the mounting member 113 is cylindrical, its axial direction is the same as the axial direction of the cavity body 1110, and its diameter matches the diameter of the cavity body 1110. Specifically, the mounting member 113 can be slightly smaller than the diameter of the cavity body 1110. As can be understood, in other embodiments, the mounting member 113 is not limited to a cylindrical shape, but may be a rectangular prism or other shape. In this embodiment, the mounting member 113 may be a ceramic body, a quartz tube, or other insulating structure. In some embodiments, the mounting member 113 can be manufactured from alumina or zirconia.

[0044] In this embodiment, the mounting member 113 can include a first end 113a and a second end 113b. Both the first end 113a and the second end 113b are located in the axial direction of the mounting member 113 and are installed opposite to each other. The first end 113a may be located outside the pipe body 111, that is, the first end 113a may penetrate from the pipe opening 1111. As can be understood, in other embodiments, the first end 113a can also be installed close to the outside of the pipe body 111, that is, the first end 113a can be installed inside the pipe opening 1111 or close to the pipe opening 1111. Each conductive part 1122 is installed through the second end 113b and the first end 113a, and the part of each conductive part 1122 close to the first end 113a is provided in a bent manner and can penetrate from one side of the mounting member 113, thereby being able to exert a limiting effect on the mounting member 113.

[0045] In this embodiment, a passage 1131 extending from the second end 113b to the first end 113a is provided in the mounting member 113. There are two such passages 1131, and each passage 1131 is installed corresponding to one conductive part 1122 and is used for one conductive part 1122 to penetrate. In this embodiment, the two passages 1131 are installed independently and do not communicate with each other. The cross-section of the passage 1131 may be substantially circular. In other embodiments, the cross-section of the passage 1131 is not limited to a circular shape and may be square or U-shaped. Two through holes or two through grooves penetrating the second end 113b and the first end 113a can be opened in the mounting member 113, and each passage 1131 may be formed in each through hole or each through groove. As can be understood, in this embodiment, one through hole and one through groove can be opened in the mounting member 113, and the through hole may form one passage 1131, and the through groove may form the other passage 1131. In this embodiment, the cross-sectional area of the passage 1131 may be adapted to the cross-sectional area of the conductive part 1122. Specifically, the cross-sectional area of the passage 1131 may be slightly larger than the cross-sectional area of the conductive part 1122. In this embodiment, the cross-sectional area of the passage 1131 is 0.03mm 2 ~0.28mm 2 (The end values 0.03mm 2 , 0.28mm2 , and any intermediate value therein may be set. In this embodiment, the width of the cross-section of the passage 1131 may be 0.2 mm to 0.6 mm (endpoint values ​​of 0.2 mm, 0.6 mm, and any intermediate value therein). Specifically, in this embodiment, the diameter of the passage 1131 may be 0.2 mm to 0.6 mm (endpoint values ​​of 0.2 mm, 0.6 mm, and any intermediate value therein).

[0046] In this embodiment, a portion of the heating element 112 is fixed to an end face of the passage 1131 facing the heating portion 1121. Specifically, a portion of the heating element 112 may be in close contact with an end face of the passage 1131, i.e., the second end 113b. In other embodiments, a portion of the heating element 112 is fixed to at least a portion of the inner wall of the passage 1131, for example, by press-fitting a portion of the conductive portion 1122 with the passage 1131, thereby making close contact with the inner wall of the passage 1131 and achieving fixation. Fixation can be achieved by locking the conductive portion 1122, the connecting portion 1123, or the heating portion 1121 with at least a portion of the inner wall of the passage 1131, for example, by providing an engagement structure with the conductive portion 1122 or the connecting portion 1123 and the inner wall of the passage 1131 to achieve engagement.

[0047] Specifically, in this embodiment, the connecting portion 1123 is installed at the second end 113b, and more specifically, the connecting portion 1123 may be fixed to the second end 113b. In this embodiment, the heating element 112 includes a first direction and a second direction, where the first and second directions are orthogonal to each other, and the second direction may be the direction in which the conductive portion 1122 penetrates the passage 1131, i.e., the longitudinal direction of the heating element 112, and the first direction may be the transverse direction of the heating element 112. Specifically, it may be any direction in the cross-section of the heating element 112, for example, the X-axis direction or the Y-axis direction. If the cross-section of the heating element 112 has a radial direction, the first direction may be the radial direction. The dimension of the conductive portion 1122 in the first direction at one end close to the heating portion 1121 may be greater than or equal to the dimension of the passage 1131 in the first direction. That is, the dimension of the connecting portion 1123 in the first direction may be greater than or equal to the dimension of the passage 1131 in the first direction. If the connecting portion 1123 is circular, the dimension may be the diameter of the connecting portion 1123, and the cross-sectional area of ​​the connecting portion 1123 will be greater than or equal to the cross-sectional area of ​​the passage 1131, meaning that the connecting portion 1123 cannot be inserted into the passage 1131 and is fixed to the second end 113b. In other embodiments, the connecting portion 1123 is not limited to being circular, and the dimension may not be limited to the diameter of the connecting portion 1123, but may be the length or width of the cross-section of the connecting portion 1123. In other embodiments, the connecting portion 1123 may be fixed to the second end 113b by adhesive, and is not limited to fixing by increasing its dimension in the first direction. By fixing the connecting portion 1123 to the second end of the mounting member 113, the heating element 112 is fixed inside the pipe body 111, and the heating element 112 can be restricted from moving toward the pipe opening 1111. Furthermore, the heating element 112 is fixed in the center within the tube 111, allowing for the formation of a uniform gap with the tube wall of the tube 111, thereby uniformizing the temperature of the tube 111 and facilitating the installation of the heating element 112, thereby improving the installation efficiency of the heating element 112. In addition, the installation stability and reliability of the heating element 112 are enhanced. As can be understood, in other embodiments, if the connection portion 1123 is omitted, the dimension of the conductive portion 1122 in the first direction at one end near the heating portion 1121 may be greater than or equal to the dimension of the passage 1131 in the first direction.In other words, the end of the conductive part 1122 closest to the heating part 1121 may abut against the second end 113b, thereby fixing the heating part 1121 to the second end 113b. In other embodiments, the dimension of the end of the heating part 1121 closest to the conductive part 1122 in the first direction may be made larger than the dimension of the passage 1131 in the first direction. This allows the end of the heating part 1121 to abut against the end face where the second end 113b is located.

[0048] Specifically, when attaching the heating element 112 to the pipe body 111, the heating element 112 and the mounting member 113 are attached so that the connecting portion 1123 is located at the second end of the mounting member 113, and then the heating element 112 together with the mounting member 113 can be inserted into the pipe body 111. One end of the heating portion 1121, away from the conductive portion 1122, can be press-fitted with a part of the inner wall of the tip portion 111b, that is, the tip portion 111b can be pressed against it, thereby limiting the heating element 112 from moving toward the tip end of the tip portion 111b. In other words, the heating element 112 is fixed in at least two positions in the axial direction, thereby ensuring that the heating element 112 is centrally located inside the pipe body 111 and forming a uniform gap with the pipe wall of the columnar body 111a.

[0049] In this embodiment, a positioning portion 114 is installed on the outer wall of the pipe 111. The positioning portion 114 can be used for mounting the entire heating structure 11, specifically to position and mount the heating structure 11 on the bracket 12 and to facilitate the restriction of movement of the heating structure 11. In this embodiment, the positioning portion 114 is installed close to the pipe opening 1111. In this embodiment, the positioning portion 114 may be an annular structure, for example, a fixed flange. In this embodiment, the positioning portion 114 may be fixed to the outer wall of the pipe 111 via a connecting structure, specifically, the connecting structure may be a bonding structure, for example, an adhesive. As can be understood, in other embodiments, the positioning portion 114 may be integrally molded with the pipe 111, specifically, the positioning portion 114 may be integrally molded together with the pipe 111 by injection molding.

[0050] In this embodiment, the bracket 12 may include a bracket body 121, a portion of which may be fitted into the casing 30 and press-fitted with the casing 30. The bracket body 121 is provided with a housing cavity 1210, which can be used to house an extractor 40 containing an aerosol generating substrate 200. The housing cavity 1210 may also be an open structure, generally having an L-shaped opening, which may extend from the top surface of the bracket body 121 to the side wall of the bracket body 121. The bracket 12 is provided with a support wall 122, which can be used to support the extractor 40. In this embodiment, the bracket 12 is provided with a mounting hole 123, which may be located on the support wall 122 and is used to penetrate a portion of the heating structure 11. In this embodiment, the mounting hole 123 can pass through a portion of the pipe body 111. Specifically, the portion of the pipe body 111 located away from the pipe opening 1111 of the positioning portion 114 can pass through the mounting hole 123.

[0051] In this embodiment, the heating component 10 further includes a base 13, which is installed at the bottom of the bracket body 121. The base 13 includes a bottom wall 131 and a limit structure 132 installed on the bottom wall 131. The bottom wall 131 is located at one end of the bracket 12 and presses down on the mounting member 113 that penetrates through the pipe opening 1111, thereby fixing the mounting member 113 inside the pipe body 111. The limit structure 132 is located inside the bracket 12, specifically, on the side of the support wall 122 away from the housing cavity 1210. The limit structure 132 works in cooperation with the positioning part 114 to perform a limiting action, restricting the movement and rotation of the positioning part 114, and consequently restricting the movement and rotation of the heating component 11. Specifically, in this embodiment, the limit structure 132 can surround the outer circumference of the positioning part 114, thereby restricting the rotation of the positioning part 114. In this embodiment, a limit boss 1321 is installed on the inner wall of the limit structure 132, and the limit boss 1321 presses against the positioning part 114, restricting the movement of the positioning part 114. In this embodiment, the base 13 is detachably connected to the bracket 12. When installing the heat generating component 10, the heat generating structure 11 is first attached to the base 13, and then a portion of the tubular body 111, which is the heat generating structure 11, is inserted into the housing cavity 1210 through the mounting hole 123, and the heat generating structure 11 and the base 13 are attached to the bracket 12 as a single unit. By installing the base 13 detachably, the replacement of the heat generating structure 11 can be easily made.

[0052] In this embodiment, the heating component 10 further includes a sealing structure 14, which is installed between the outer wall of the heating structure 11 and the inner wall of the mounting hole 123. Specifically, the sealing structure 14 is mounted on the outer circumference of the pipe 111, located away from the pipe opening 1111 of the positioning portion 114, and fitted into the mounting hole 123 to seal the gap between the heating structure 11 and the mounting hole 123. It is used to dampen vibrations and prevent aerosols from leaking out of the mounting hole 123. In this embodiment, the sealing structure 14 may be a sealing ring, such as a rubber ring or a silicone ring.

[0053] Figure 9 shows a second embodiment of the aerosol generator of the present invention. This differs from the first embodiment in the following respects. The heating element 1121 has its maximum radial dimension or width at the end closest to the tip 111b. Specifically, the heating element 1121 includes a spiral portion 1124 installed close to the tip 111b, and an annular portion 1125 at one end of the spiral portion closest to the tip 111b. The annular portion 1125 has the maximum radial dimension of the heating element 1121. That is, the diameter of the annular portion 1125 is larger than the diameter of the cross-section of the heating element 1121 at other locations, so that the end of the heating element 1121 closest to the tip 111b acts as a mounting limit and ensures that the middle portion of the heating element 1121 does not come into direct contact with the inner wall of the pipe 111. Furthermore, the heat dissipation area can be increased, resistance can be reduced, and the temperature of the end of the heat-generating section 1121 near the tip 111b can be prevented from rising excessively. As can be understood, the radial dimension of the annular section 1125 may be the same as the radial dimension of the helical section, and it is sufficient to ensure that there is a gap between the helical section and the tube wall, and that this gap is controlled to 0.05 mm to 0.5 mm (including endpoint values ​​of 0.05 mm, 0.5 mm, and any intermediate value).

[0054] As shown in Figure 9, one end of the helical portion 1124 near the tip 111b includes a top, which has a set axial height h. The resistance of the helical portion adjacent to the top at the same height h is greater than the resistance of the top. That is, the resistance of the top where the heating element 1121 is combined with the tip 111b is relatively low, and the amount of heat generated at the top of the heating element 1121 when energized is less than that of other parts. This prevents the top temperature of the heating structure 11 from rising excessively, prevents charring of the aerosol generating substrate 200, and improves the flavor of the aerosol. In some embodiments, the helical portion may include a helical portion and a straight portion located inside the helical portion, or it may include only the helical portion.

[0055] Figure 10 shows a third embodiment of the aerosol generator of the present invention. This differs from the second embodiment in the following respects. The heating element 1121 includes a spiral section 1124 near the tip 111b, and the radial dimension or width dimension of the end of the spiral section 1124 near the tip 111b is smaller than the maximum radial dimension of the spiral section 1124. In this embodiment, the portion of the spiral section 1124 near the tip 111b includes a bent portion 1126, and the width of the bent portion is smaller than the maximum radial dimension of the spiral section. That is, the width dimension of the top of the heating element 1121 is relatively small, and it works in cooperation with the tip 111b of the tube body 111 to act as a limiting force, while at the same time reducing the contact area with the tip 111b, thereby reducing heat generation and light wave radiation. In other words, the temperature of one end near the tip 111b is lower than the temperature of the portion further away from the tip 111b, thereby preventing the top temperature of the heating structure 11 from rising excessively. Furthermore, by reducing the width dimension of the top of the heating element 1121, the heat capacity of the heating element 1121 can also be reduced.

[0056] Figure 11 shows a fourth embodiment of the aerosol generator of the present invention. This differs from the second embodiment in the following respects: The distance between the annular portion 1125 and the adjacent helical portion is greater than the pitch of the helical portion, and the helical portion away from the annular portion 1125 is installed at a distance from the inner wall of the tube 111. This reduces the light wave radiation generated when the heating portion 1121 is energized, thereby preventing the top temperature of the heating structure 11 from rising excessively, preventing charring of the aerosol generating substrate 200, and improving the flavor of the aerosol.

[0057] Figure 12 shows a fifth embodiment of the aerosol generator of the present invention. This differs from the third embodiment in the following respects: The distance between the bent portion 1126 and the adjacent spiral portion is greater than the pitch of the spiral portion, and the spiral portion away from the bent portion 1126 is installed at a distance from the inner wall of the tube 111. This reduces the light wave radiation generated at the top of the heating portion 1121 when energized, thereby preventing the top temperature of the heating structure 11 from rising excessively, preventing charring of the aerosol generating substrate 200, and improving the flavor of the aerosol.

[0058] In other embodiments, the end of the helical portion closest to the tip 111b is not limited to including a bent portion 1126 or an annular portion 1125. The end of the helical portion 1124 closest to the tip 111b may include only one tip or flattened portion. The width of the tip or flattened portion can be smaller than the outer diameter of the helical portion 1124, and the tip and flattened portion abut against the top of the tip 111b. The helical portion 1124 of the heating element 1121, away from the tip or flattened portion, may be installed at a distance from the inner wall of the tube 111. That is, the heating element 1121 cooperates with the tip 111b via the tip or flattened portion to perform a limiting action, and by being provided as a tip or flattened portion, the light wave radiation generated when energized can be reduced. This prevents the top temperature of the heating structure 11 from rising excessively, prevents charring of the aerosol generating substrate 200, and improves the flavor of the aerosol.

[0059] In other embodiments, a limit portion is provided between the heating element 1121 and the mounting member 113 to define the distance between the heating element 1121 and the mounting member 113. Specifically, the limit portion may be the end of the heating wire or an insulating sleeve attached to the conductive part 1122, and for example, the insulating sleeve can be made of alumina, zirconia, or other materials. The limit portion may also be the thickened portion of the end of the heating wire or the thickened portion of the conductive part 1122. The limit portion is limited on the upper surface of the mounting member 113, and in either case, its purpose is to define the position after the conductive part 1122 has penetrated the mounting member 113. This is advantageous for mass production, ensures consistency in the heating structure, and ultimately contributes to temperature control and flavor during inhalation.

[0060] As should be understood, the above embodiments illustrate preferred embodiments of the present invention, and while their description is specific and detailed, it should not be understood that this limits the scope of the claims of the present invention. Those skilled in the art may freely combine the above technical features and make several modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made within the same scope as the claims of the present invention shall be included within the claims of the present invention.
