Description

Technical Field

[0001] This application relates to the field of heating atomization and aerosol generation technology for heating without combustion, specifically to an aerosol generation device, and also to a heating without combustion atomization appliance including the above-mentioned aerosol generation device. Background Technology

[0002] Heated tobacco products (HNB) are a new type of tobacco product that simulates the smoking experience of traditional cigarettes by heating rather than burning them.

[0003] In the field of heated tobacco products, infrared radiation heating, compared to contact heat conduction heating, eliminates the need for a heat transfer medium during the heating process, resulting in a healthier, less polluting smoking experience and more uniform heating. However, currently available infrared radiation HNB (heated in-house heating) devices generally have their heating atomization (i.e., aerosol generation) devices in direct contact with the cigarette. Heat conduction remains the primary heat transfer method, with less infrared radiation heating and poorer uniformity, thus impacting the smoking experience. Utility Model Content

[0016] Preferably, in the above-mentioned aerosol generating device, the sidewall of the light-transmitting seat includes a frustum-shaped side surface that gradually expands from one end connected to the support sleeve in a direction away from the support sleeve.

[0017] The radiation flux control cover is placed over the frustum-shaped side surface, and the end of the radiation flux control cover connected to the light-shielding base is flush with the end of the frustum-shaped side surface away from the support sleeve.

[0018] Preferably, in the above-mentioned aerosol generating device, the radiation flux control hood includes:

[0019] An annular cover plate, at least surrounding the outer periphery of the support sleeve;

[0020] A flat cover plate is provided on the inlet end of the support sleeve away from the support base. The flat cover plate has a through hole for the aerosol generating substrate to pass through, and the through hole communicates with the placement cavity.

[0021] The planar cover plate is closed at one end opening of the annular cover plate, and the light-reflecting surface includes the inner surface of the annular cover plate and the inner surface of the planar cover plate.

[0022] Preferably, in the above-mentioned aerosol generating device, the outer side of the radiation flux control hood is wrapped with a heat insulation layer.

[0023] Preferably, in the above-mentioned aerosol generating device, the heating wire and the support sleeve are arranged coaxially, and the infrared radiation energy of the heating wire is uniformly distributed along the circumference of the support sleeve;

[0024] And / or, the heating wire is spiral-shaped.

[0025] Preferably, in the above-mentioned aerosol generating device, the inner diameter d1 of the support sleeve is 2r + a, where r is the radius of the aerosol generating substrate and a is the target assembly tolerance;

[0026] The outer diameter d2 of the support sleeve is d1 + 4*δ + 2m, where δ is the shell thickness of the support sleeve and m is the distance between the inner shell and the outer shell of the support sleeve.

[0027] The dimension w of the light-transmitting base along the arrangement direction of the two pins of the conductive structure is greater than d2.

[0028] As can be seen from the above technical solution, the aerosol generating device provided in this application includes a heat-resistant support, an infrared heating element, and a radiation flux control cover; wherein, the heat-resistant support is provided with a placement cavity for placing the aerosol generating substrate, the heat-resistant support includes a support base and a support sleeve disposed on the support base, the inner wall of the cavity of the support sleeve and the support base cooperate to form the placement cavity, at least the support sleeve is light-transmitting, and the support sleeve has a heating cavity; the infrared heating element includes a heating wire capable of providing infrared radiation energy to heat and atomize the aerosol generating substrate in the placement cavity and a conductive structure electrically connected to the heating wire, the heating wire is disposed in the heating cavity, and the conductive structure is disposed on the heat-resistant support; the radiation flux control cover at least covers the support sleeve, and there is a uniform light gap between the inner side of the radiation flux control cover and the outer side of the support sleeve, the inner surface of the radiation flux control cover is a light reflecting surface capable of uniformly radiating infrared radiation energy from the infrared heating element to the uniform light gap.

[0029] When the aerosol generating apparatus provided in this application is used, the aerosol generating substrate is placed in the placement cavity of the heat-resistant support member; and the conductive structure of the infrared heating element supplies power to the heating wire of the infrared heating element, causing the heating wire to generate infrared light waves. The infrared light waves emit infrared radiation energy from the light-transmitting support sleeve to the outside of the heating cavity. On the one hand, the infrared radiation heats the aerosol generating substrate through the inner shell of the support sleeve. On the other hand, the infrared radiation enters the uniform light gap between the inner side of the radiation flux control cover and the outer side of the support sleeve through the outer shell of the support sleeve. After being uniformly reflected by the light reflection surface formed on the inner surface of the radiation flux control cover, the infrared radiation heats the aerosol generating substrate through the outer shell and inner shell of the support sleeve. At the same time, the infrared radiation generated by the heating wire can heat the inner shell of the support sleeve, and the inner shell conducts heat to the aerosol generating substrate, causing the aerosol generating substrate to be heated and atomized.

[0030] Therefore, it can be seen that the infrared radiation energy generated by the heating wire of the infrared heating element of the aerosol generation device provided in this application is used to heat the aerosol generation substrate through the light-transmitting support sleeve and the radiation flux control cover. Infrared radiation heating is the main heat transfer method.

Detailed Implementation

[0052] This application provides an aerosol generating device and a heated non-combustible atomizing device including the above-mentioned aerosol generating device, which improves the inhalation experience.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] like Figures 1-9 As shown, the aerosol generating device provided in this embodiment includes a heat-resistant support, an infrared heating element, and a radiation flux control cover 10. The heat-resistant support has a placement cavity A for the aerosol generating substrate 13 to be placed inside. The heat-resistant support includes a support base and a support sleeve 1 disposed on the support base. The inner wall of the cavity of the support sleeve 1 cooperates with the support base to form the placement cavity A. At least the support sleeve 1 is light-transmitting and has a heating cavity. The infrared heating element includes a heating wire 4 capable of providing infrared radiation energy to heat and atomize the aerosol generating substrate 13 in the placement cavity A, and a conductive structure electrically connected to the heating wire 4. The heating wire 4 is disposed inside the heating cavity, and the conductive structure is disposed on the heat-resistant support. The radiation flux control cover 10 at least covers the support sleeve 1, and there is a uniform light gap between the inner surface of the radiation flux control cover 10 and the outer surface of the support sleeve 1. The inner surface of the radiation flux control cover 10 is a light-reflecting surface capable of uniformly radiating infrared radiation energy from the infrared heating element into the uniform light gap.

[0055] It should be noted that the heating cavity of the support sleeve 1 is formed by the outer shell and the inner shell of the support sleeve 1. Unlike the placement cavity A, the heating cavity is preferably annular, which can improve the uniformity of the infrared radiation energy of the heating wire 4 along the circumference of the support sleeve 1 and facilitate the placement of the heating wire 4.

[0056] The uniform light gap between the inner side of the radiation flux control cover 10 and the outer side of the support sleeve 1 is usually selected as 2mm to 2*d2, where d2 is the outer diameter of the support sleeve. This can improve the utilization rate of infrared radiation energy and the heating uniformity, while also improving the structural compactness.

[0057] When the aerosol generating apparatus provided in this application is used, the aerosol generating substrate 13 is placed in the placement cavity A of the heat-resistant support member; and the conductive structure of the infrared heating element supplies power to the heating wire 4 of the infrared heating element, causing the heating wire 4 to generate infrared light waves. The infrared light waves emit infrared radiation energy from the light-transmitting support sleeve 1 to the outside of the heating cavity. On the one hand, the infrared light waves pass through the inner shell of the support sleeve 1 to perform infrared thermal radiation heating on the aerosol generating substrate 13. On the other hand, the infrared light waves pass through the outer shell of the support sleeve 1 and enter the uniform light gap between the inner side of the radiation flux control cover 10 and the outer side of the support sleeve 1. After being uniformly reflected by the light reflection surface formed on the inner surface of the radiation flux control cover 10, the infrared light waves pass through the outer shell and inner shell of the support sleeve 1 to perform infrared thermal radiation heating on the aerosol generating substrate 13. At the same time, the infrared radiation generated by the heating wire 4 can heat the inner shell of the support sleeve 1, and the inner shell conducts heat to the aerosol generating substrate 13, causing the aerosol generating substrate 13 to be heated and atomized.

[0058] Therefore, it can be seen that the infrared radiation energy generated by the heating wire 4 of the infrared heating element of the aerosol generation device provided in this application is used to heat the aerosol generation substrate 13 by infrared thermal radiation through the light-transmitting support sleeve 1 and the radiation flux control cover 10. Infrared radiation heating is the main heat transfer method. At the same time, the light reflection surface of the radiation flux control cover 10 is used to improve the heating uniformity, which can achieve a healthier and less polluting suction experience and improve the suction experience.

[0059] It should be noted that the heating wire 4 in this embodiment is an electric heating wire that can generate infrared light waves when energized, preferably a tungsten wire, but it can also be a wire of other materials that meet the requirements of infrared radiation.

[0060] Specifically, the aerosol generating substrate 13 can be a cigarette or other structure that requires heating and atomization, such as aromatherapy products. This application does not limit the aerosol generating substrate 13.

[0061] When the aerosol-generating substrate 13 is a cigarette, the absorption peaks of the tobacco and the main smoke-generating agent glycerol are in the near-infrared and short-wave mid-infrared ranges. This leads to strong absorption near the radiation source, significantly reducing infrared penetration. To ensure uniform heating of the cigarette, near-infrared or short-wave mid-infrared heating is required. The tungsten filament of the infrared heating element typically reaches a temperature of 2500–3000℃ during operation. According to Wien's displacement law, the peak wavelength... This indicates that the infrared heating element is an excellent near-infrared and short-wave mid-infrared generator, which matches the infrared thermal radiation absorption range of HNB cigarettes and has high heat transfer efficiency.

[0062] The support sleeve 1 is cylindrical, preferably cylindrical. This makes the placement cavity A a cylindrical cavity, which can better match the cylindrical cigarette. This allows for the insertion and positioning of the aerosol generating substrate 13 (i.e., the atomizing matrix) such as the cigarette, ensuring the stability of the support for the cigarette and the uniformity of effective heating, and avoiding mismatch between the internal aerosol generating substrate 13 and the area where the infrared heating element is located.

[0063] Of course, depending on the actual shape of the aerosol generating substrate 13, the support sleeve 1 can also be other shapes, such as ellipse, polygon, etc.

[0064] The conductive structure is set on the support base, such as Figure 2-3 As shown, the conductive structure includes a filament foot, a molybdenum sheet 5, and two electrode pins 3. The electrode pins 3 extend from the support base and are used to connect to the power supply electronic components.

[0065] like Figure 8-9 As shown, preferably, the support base includes a light-transmitting base 2, which cooperates with the support sleeve 1 to form a placement cavity A, and the support sleeve 1 is disposed on one side of the light-transmitting base 2; a light-shielding base 6, which wraps around the other side of the light-transmitting base 2, and a radiation flux control cover 10 is sealed to the light-shielding base 6. In this embodiment, both the light-transmitting base 2 and the support sleeve 1 are light-transmitting. The infrared light waves generated by the heating wire 4 of the infrared heating element are emitted as infrared radiation energy from the light-transmitting support sleeve 1 and the light-transmitting base 2 to the outside of the heating cavity. At this time, the light-transmitting base 2, which is opposite to the placement entrance of the placement cavity A, also heats up due to absorbing part of the infrared radiation, thereby realizing the placement end face (i.e., the aerosol generating substrate 13) of the aerosol generating substrate 13. Figure 8-9 The bottom surface of the substrate is heated by heat conduction, which improves the heating and atomization efficiency of the aerosol generating substrate 13. Furthermore, the support base absorbs infrared radiation through the light-transmitting seat 2 to transfer heat to the aerosol generating substrate 13, and the light-shielding seat 6 provides fixed support for the support base and support sleeve 1, while preventing radiant energy leakage and heat loss. The support base in this application may also consist only of the light-shielding seat 6.

[0066] In the aerosol generating apparatus provided in the above embodiment, the inner surface of the radiation flux control cover 10 gradually expands from the end near the light-shielding seat 6 to the end away from the light-shielding seat 6. Since the light-transmitting seat 2 absorbs infrared radiation and heats up, the bottom surface of the aerosol generating substrate 13 in the placement cavity A receives more heat conduction heating. In this embodiment, the inner surface of the radiation flux control cover 10 gradually expands from bottom to top, so that the infrared radiation energy in the uniform light gap gradually gathers in the upper region, so that the aerosol generating substrate 13 in the placement cavity A is heated evenly in the axial direction, that is, in the vertical direction, further improving the suction experience.

[0067] like Figure 8-9As shown, in this embodiment, the inner surface of the radiation flux control cover 10 is tapered, gradually widening from bottom to top. For ease of assembly, the total assembly clearance between the support sleeve 1 and the upper and lower ends of the radiation flux control cover 10 is 4mm. Preferably, the uniform light gap between the inner surface of the radiation flux control cover 10 and the outer surface of the support sleeve 1 is 2mm at the lower end and 1.8*d² to 2*d² at the upper end, which improves the utilization rate of infrared radiation energy, enhances heating uniformity, and improves structural compactness.

[0068] The inner surface of the radiation flux control hood 10 is specifically a frustum that gradually expands from bottom to top. Of course, it can also be curved, as long as it can make the light waves gradually concentrate in the upper region.

[0069] The inner surface of the radiation flux control hood 10 can also be cylindrical, in which case the uniform light gap between the inner surface of the radiation flux control hood 10 and the outer surface of the support sleeve 1 is 2-4 mm.

[0070] To further optimize the above technical solution, the radiation flux control cover 10 is placed over the side wall of the light-transmitting base 2 near the supporting sleeve 1. In this way, the light-reflecting surface formed on the inner surface of the radiation flux control cover 10 can uniformly reflect the infrared light waves radiated from the side wall of the light-transmitting base 2 near the supporting sleeve 1, further improving the utilization rate of infrared radiation energy and enhancing heating uniformity. The radiation flux control cover 10 can also be placed over the entire side wall of the light-transmitting base 2, or it can be placed only over the supporting sleeve 1.

[0071] In a specific embodiment, the sidewall of the light-transmitting base 2 includes a frustum-shaped side surface that gradually expands from the end connected to the support sleeve 1 in a direction away from the support sleeve 1; the radiation flux control cover 10 covers the frustum-shaped side surface, and the end of the radiation flux control cover 10 connected to the light-shielding base 6 is flush with the end of the frustum-shaped side surface away from the support sleeve 1.

[0072] like Figure 8 As shown, the frustum-shaped side of the upper part of the light-transmitting seat 2 gradually expands from top to bottom, which facilitates the transmission of infrared light waves in the light-transmitting seat 2 to the uniform light gap. The bottom end of the radiation flux control cover 10 is flush with the bottom end of the frustum-shaped side, which can better concentrate the infrared radiation energy upward while uniformly radiating infrared radiation, thereby improving the heating uniformity of the aerosol generating substrate 13 in the vertical direction in the placement cavity A.

[0073] To simplify the structure, the radiation flux control hood 10 includes an annular cover plate, at least surrounding the outer periphery of the support sleeve 1; and a planar cover plate, covering the inlet end of the support sleeve 1 away from the support base. The planar cover plate has a perforation through which the aerosol generating substrate 13 passes, and the perforation communicates with the placement cavity A. The planar cover plate closes at one end of the annular cover plate's opening, and the light-reflecting surface includes the inner surface of both the annular cover plate and the planar cover plate. In this embodiment, the radiation flux control hood 10 is a frustum-shaped semi-enclosed hood formed by the annular cover plate and the planar cover plate. Both the inner surfaces of the annular cover plate and the planar cover plate can reflect light, increasing the amount of infrared radiation reflected, thereby improving the utilization rate of infrared radiation and heating efficiency.

[0074] Specifically, the radiation flux control cover 10 is a frustum-shaped structure, wider at the top and narrower at the bottom. The light-reflecting surface formed on the inner surface of the radiation flux control cover 10 can effectively receive infrared light waves emitted by the infrared heating element and reflect them to the upper part of the cigarette, creating a certain light wave focusing effect. The bottom of the cigarette contacts the light-transmitting base 2, which has a certain high temperature when the infrared heating element is working, so the lower part of the cigarette receives better heating. Therefore, the structure of the radiation flux control cover 10 enables the infrared heating element to heat the cigarette more evenly, which is beneficial to creating a better smoking experience.

[0075] The radiation flux control cover 10 is a reflective aluminum shell, but it can also be a shell formed of other light-reflective materials to achieve a light-reflective surface on the inner surface. The light-reflective surface can also be formed by coating the inner wall of the radiation flux control cover 10 with an aluminum film or other light-reflective films.

[0076] In the aerosol generating apparatus provided in the above embodiments, a heat insulation layer 9 is wrapped around the outside of the radiation flux control hood 10. To simplify the structure, the heat insulation layer 9 is wrapped around the outside of the annular cover plate of the radiation flux control hood 10 to prevent heat loss and ensure heating efficiency.

[0077] The heating wire 4 and the support sleeve 1 are arranged coaxially, and the infrared radiation energy of the heating wire 4 is uniformly distributed along the circumference of the support sleeve 1. In this embodiment, the infrared radiation intensity of the infrared heating element is uniformly distributed in all radial directions throughout the circumference, that is, the infrared radiation energy of the infrared heating element is isotropic about its axis. In this way, the infrared heating element can provide more uniform infrared radiation energy to the uniform light gap between the inner side of the radiation flux control cover 10 and the outer side of the support sleeve 1, further improving the heating uniformity.

[0078] To simplify the structure, the heating wire 4 is spiral-shaped. For example... Figure 3 As shown, the heating wire 4 has a vertical spiral shape. This shape of the heating wire 4 can emit infrared radiation light waves uniformly in the radial direction, so that the side of the cigarette receives a uniformly distributed heat radiation flux.

[0079] In this embodiment of the application, the light-transmitting base 2, the support sleeve 1, and the infrared heating element are connected to form an integrated structure to form an infrared halogen lamp. The aerosol generating device mainly uses the infrared halogen lamp to generate infrared light waves, which heat and atomize the aerosol generating substrate 13, such as cigarettes, by infrared light wave thermal radiation.

[0080] The specific design of this infrared halogen lamp is as follows:

[0081] First, the main structural dimensions of the infrared halogen lamp are determined based on the suction capacity of the corresponding NHB cigarette or other aerosol generating substrate 13, so as to achieve the positioning and matching of the aerosol generating substrate 13 during the suction process.

[0082] The inner diameter of the support sleeve 1 is designed as d1 = 2r + a, where r is the radius of the aerosol generating substrate 13, and a is the target assembly tolerance. Specifically, in the NHB cigarette, the height of the tobacco portion is h, the cigarette radius is r, and a is chosen to be 0.2 mm. In this case, the inner diameter of the support sleeve 1 is d1 = 2r + 0.2. The target assembly tolerance a can also be chosen from other numerical ranges.

[0083] The outer diameter of the support sleeve 1 is designed as d2 = d1 + 4*δ + 2m, where δ is the shell thickness of the support sleeve 1, which can be 0.5mm or other values; m is the distance between the inner shell and the outer shell of the support sleeve 1. To ensure the effective positioning of the tungsten wire in the shell interlayer space, m ≥ 1mm is generally required, otherwise the assembly will be more difficult.

[0084] The dimensions w of the light-transmitting base 2 along the two pin arrangement directions of the conductive structure are greater than d2, where w is the left and right width of the light-transmitting base 2 housing. Based on the straight cylindrical structure of the infrared halogen lamp housing, the dimension w of the bottom light-transmitting base 2 housing can be determined as w = d2 + 2. This means the width of the light-transmitting base 2 housing needs to be larger than the size of the supporting sleeve 1 housing to ensure sufficient space for pin assembly in the infrared halogen lamp. The height and thickness of the light-transmitting base 2 body can be determined based on the height and thickness of the clamping glass housing section of a traditional low-voltage halogen lamp of the same power; no special requirements are specified.

[0085] Preferably, the heating wire 4 is in a double helix shape. Specifically, the heating wire 4 inside the infrared halogen lamp adopts a double helix tungsten wire structure. The heating wire 4 adopts a double helix circumferential heating form, which is conducive to the uniform heating of the internal aerosol generation substrate 13 and has a good consistency effect.

[0086] The two sides of the heating wire 4 have the same spiral structure, that is, the diameter, pitch and tilt angle of the spiral are the same, which facilitates the manufacturing and installation of the structure and saves space.

[0087] In the infrared halogen lamp provided in this application embodiment, the pitch t of the single-sided spiral of the heating wire 4 is calculated by the following formula:

[0088]

[0089] Where L is the overall length of heating wire 4, which is calculated based on the length of heating wire 4 required per V voltage obtained from the target life of heating wire 4 and the target operating voltage U of heating wire 4.

[0090] D is the spiral diameter of heating wire 4. 0.5πD is the length of the connecting section between the spirals on both sides of the heating wire 4;

[0091] H is the target height of heating wire 4, where H = h + n*(S / π). 0.5 h is the height of the aerosol generation section of the aerosol generation substrate 13, n is the target proportional coefficient; S is the cross-sectional area of ​​the heating wire 4, which is calculated based on the mass requirement of the heating wire 4 per mm length and the density of the heating wire 4 obtained from the target life and target operating current I of the heating wire 4; the target operating current of the heating wire 4 is I = P / U, where P is the target rated power of the heating wire 4.

[0092] In this embodiment, the heating wire 4 is specifically designed with the following dimensions as a tungsten wire:

[0093] According to the references in "Principles of Electric Light Sources" and "Electric Light Source Technology" from Fudan University, the calculation of the length and cross-sectional area of ​​the tungsten wire must meet the following table.

[0095] Design life / h Quality requirements per mm length of tungsten wire tungsten wire length requirement per volt 1000 <![CDATA[(15.5 / 200)*I 1.31 ]]> <![CDATA[5*I 1 / 3.55 ]]> 500 <![CDATA[(14.8 / 200)*I 1.31 ]]> <![CDATA[4.64*I 1 / 3.55 ]]> 300～400 <![CDATA[(14.5 / 200)*I 1.31 ]]> <![CDATA[4.5*I 1 / 3.55 <!-- 7 -->]]> 200～250 <![CDATA[(14.2 / 200)*I 1.31 ]]> <![CDATA[4.35*I 1 / 3.55 ]]> 100～150 <![CDATA[(13.6 / 200)*I 1.31 ]]> <![CDATA[4.0*I 1 / 3.55 ]]> 40～80 <![CDATA[(13.6 / 200)*I 1.31 ]]> <![CDATA[3.7*I 1 / 3.55 ]]>

[0096] According to the tungsten wire structure dimension design calculation table, once the overall current I passing through the tungsten wire is determined, different calculation formulas in the table can be selected for calculation based on the design life requirements of the tungsten wire: ① Calculate the mass requirement of the tungsten wire per mm length, and then calculate the cross-sectional area S of the tungsten wire based on the density of the tungsten wire and the mass calculation formula; ② Calculate the length of the tungsten wire required per V voltage, and then calculate the total length L of the tungsten wire based on the design voltage of the tungsten wire.

[0097] Furthermore, by determining the helical diameter and tungsten filament height, the pitch t of the tungsten filament can be calculated, thus completely determining the structure of the tungsten filament. The helical diameter D is determined by the inner and outer diameters of the straight section shell, and the designed tungsten filament height H is determined by the height h of the tobacco portion in the NHB cigarette, as shown in the following two formulas:

[0098] H = h + n*(S / π) 0.5

[0099] Since the spiral tungsten filament heating element in this embodiment adopts a double spiral structure, and the length of the connecting section between the two spirals at the top is 0.5πD, the spiral length on one side can be expressed as 0.5*(L﹣0.5πD). Furthermore, the spiral length on one side can be calculated using the pitch t and the spiral diameter D, as shown in the following formula:

[0100]

[0101] Therefore, the pitch t can be calculated by reverse deduction, thus completely determining the tungsten wire structure.

[0102] To further optimize the above technical solution, the light-transmitting base 2, the supporting sleeve 1, and the infrared heating element are connected into an integrated structure. The manufacturing process of this integrated structure includes the following steps:

[0103] S1. A metal rod is placed on the top of the double-layer annular shell 101, and the top surface of the double-layer annular shell 101 is sintered and fused together. At the same time, molten light-transmitting material is attached to the surface of the metal rod. After the molten light-transmitting material cools, the metal rod is removed to form an exhaust pipe 102.

[0104] like Figure 4 As shown, the double-layer annular shell 101 is specifically a double-layer cylindrical glass shell, and the top surface of the double-layer cylindrical glass shell is sintered and fused together; the molten light-transmitting material is specifically molten quartz material.

[0105] S2. First, position and weld the heating wire 4 and the conductive structure to form an infrared heating element. Then, place the heating wire 4 in the interlayer gap of the double-layer annular shell 101, and expose the conductive structure below the bottom of the double-layer annular shell 101. Next, sinter and melt the bottom surface of the double-layer annular shell 101 to close the bottom space and form the support sleeve 1. Figure 5 As shown;

[0106] First, the tungsten filament and conductive structure filament feet, molybdenum sheet 5 and electrode pins 3 are positioned and welded, and placed in the interlayer gap of the double-layer cylindrical glass shell processed in step S1. The molybdenum sheet 5 and electrode pins 3 are exposed below the bottom of the glass shell. Then, the bottom surface is sintered and melted to close the bottom space. Since the melting point of molybdenum sheet 5 is higher than the sintering temperature of quartz material, this process does not damage the structure of molybdenum sheet 5 and electrode pins 3.

[0107] S3. The top of the light-transmitting and heat-resistant pipe section 103 is fused and sintered with the bottom of the support sleeve 1. At the same time, the light-transmitting and heat-resistant pipe section 103 is heated and softened. The exposed conductive structure is sealed inside the light-transmitting and heat-resistant material using a clamping process.

[0108] like Figure 6As shown, the light-transmitting and heat-resistant tube section 103 is specifically a glass tube section with an inner diameter equal to the outer diameter of the glass shell and a thickness of 1mm. The top of the tube section is fused and sintered to the bottom of the double-layer cylindrical glass shell. Simultaneously, the glass tube section undergoes a heating and softening treatment. A clamping process is used to tightly seal the exposed molybdenum sheet sections 5 segments inside the glass, ensuring the airtightness of the finished product. Figure 7 As shown.

[0109] S4. The air inside the support sleeve 1 is extracted through the exhaust pipe 102, and an inert gas mixed with bromide is introduced to fill the heating chamber of the support sleeve 1 with the gas mixture. Finally, the exhaust pipe 102 is softened, melted and removed.

[0110] The air inside the existing finished product is extracted, and an inert gas mixed with bromide is introduced to fill the entire heating internal space of the infrared halogen lamp. Finally, the exhaust pipe 102 is softened, melted and removed, thus completing the fabrication of the infrared halogen lamp of this application.

[0111] The infrared halogen lamp formed in this embodiment is similar in structure to the glass shell of traditional low-pressure halogen lamps on the market. It is easy to use the traditional halogen lamp manufacturing process to manufacture the infrared halogen lamp. It can effectively position and weld the tungsten filament, filament foot, and molybdenum sheet 5. The clamping seal ensures the overall airtightness and reliability, and is feasible.

[0112] In summary, the aerosol generating device provided in this application embodiment achieves infrared light wave heating of the atomizing matrix such as HNB cigarettes, meeting users' needs for healthier use of heated non-combustible inhalation.

[0113] This application also provides a heated non-combustible atomizing device, including an aerosol generating device for heating and atomizing and an electronic component for supplying power to the aerosol generating device. The electronic component is electrically connected to the aerosol generating device. The aerosol generating device is the aerosol generating device provided in any of the above embodiments, which improves the inhalation experience. Its advantages are brought about by the above aerosol generating device. For details, please refer to the relevant parts in the above embodiments, which will not be repeated here.

[0114] When the heated non-combustible atomizing device of this application is used, the aerosol generating device is powered by electronic components, and the aerosol generating substrate 13 is heated and atomized by the aerosol generating device.

[0115] Specifically, the aerosol generating substrate 13 can be a cigarette or other structures that require heating and atomization, such as aromatherapy products. When the aerosol generating substrate 13 is a cigarette, the heated non-combustible atomizing device forms a heated non-combustible smoking device. This device achieves infrared light wave heating of the atomizing substrate such as the HNB cigarette, meeting users' needs for a healthier heating non-combustible smoking experience.

[0116] Preferably, the above-mentioned heated non-combustible atomizing device further includes a first conductive element 11, disposed at a position corresponding to the inlet of the heat-resistant support; a second conductive element 12, movably disposed radially between the inlet and the first conductive element 11 along the heat-resistant support, the second conductive element 12 being able to make electrical contact with the first conductive element 11; and an elastic element 15, capable of driving the second conductive element 12 to separate from the first conductive element 11, the elastic element 15 being connected to the second conductive element 12; wherein, when the aerosol generating substrate 13 is placed in the placement cavity A of the heat-resistant support, the aerosol generating substrate 13 is able to drive the second conductive element 12 to move towards the first conductive element 11 and make the first conductive element 11 and the second conductive element 12 make electrical contact; one of the first conductive element 11 and the second conductive element 12 is electrically connected to the positive electrode of the electronic component, and the other is electrically connected to the negative electrode of the electronic component.

[0117] like Figure 8-11 As shown, the aerosol generating device is installed at the top of the housing 7 of the heated non-combustible atomizing device, and is supported by a bracket 8 inside the housing 7. The first conductive element 11, the second conductive element 12, and the elastic element 15 form a circuit breaker protection assembly, which is located between the top of the aerosol generating device and the top cover 14 of the housing 7 and is limited and fixed by the bracket 8, thus realizing the circuit breaker protection function of the whole machine. Specifically, the first conductive element 11 and the second conductive element 12 are both columnar or rod-shaped; the elastic element 15 is a spring, which is sleeved on the second conductive element 12; the first conductive element 11 and the second conductive element 12 are respectively connected to the positive and negative terminals of the output terminals of the electronic components.

[0118] When no cigarette is inserted into the heated tobacco atomizer, the second conductive element 12 extends above the inlet of the heat-resistant support under the action of the spring, preventing it from contacting the first conductive element 11 and thus creating an open circuit in the system. When a cigarette is inserted into the heated tobacco atomizer, the cigarette structure compresses the spring through the second conductive element 12, causing the second conductive element 12 to move out of the inlet and contact the first conductive element 11, thus establishing an electrical connection in the system. This ensures that the device cannot be started when no cigarette is inserted, preventing infrared radiation leakage and improving safety.
