Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] In the field of aerosol generation devices, traditional heating methods have always had many problems that need to be solved.

[0003] Currently, most aerosol generators on the market use resistance heating or induction heating. However, these devices have a significant drawback: users have to endure a long waiting time before they can smoke, which greatly affects the smoking experience and reduces user satisfaction.

[0004] To improve heating efficiency, some devices employ photothermal technologies, with halogen lamps and incandescent lamps being common light sources. While these can heat the aerosol-generating matrix, they have significant limitations. Firstly, halogen and incandescent lamps have low luminous efficiency and brightness, resulting in longer heating times and failing to meet users' demands for rapid heating. Secondly, because these lamps emit diffuse light, their light utilization rate is low when directly used for low-temperature smoke heating, with a large amount of light failing to effectively reach the aerosol-generating product, leading to excessive energy consumption.

[0005] Traditional light heating sources, such as halogen lamps and incandescent lamps, can heat low-temperature smoke, but their problems of low light utilization and high energy consumption remain prominent. Furthermore, only a small portion of the diffused light radiated by the filament heating can be used for heating low-temperature smoke, resulting in poor overall heating effect and difficulty in achieving ideal heating speed and quality. Utility Model Content

[0006] The purpose of this invention is to provide an aerosol generating device to improve heating efficiency, reduce energy consumption, and reduce the difficulty of cleaning.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] An aerosol generating device is provided for heating an aerosol-generating product. The surface of the aerosol generating device has a receiving groove, and the aerosol-generating product can be inserted into the receiving groove along its depth direction. The aerosol generating device includes a light-heating component, which includes a focusing element and a light emitter. The focusing element includes a main body with a focusing groove inside. The opening of the focusing groove is perpendicular to the depth direction of the receiving groove. The light emitter is used to emit light and is located within the focusing groove. The sidewall of the focusing groove includes a reflective surface, which reflects the light and redirects it to propagate along the depth direction of the receiving groove, allowing the light to enter the receiving groove from the bottom to irradiate the aerosol-generating product.

[0009] As an optional technical solution for the aerosol generating device, the aerosol generating device further includes a heating chamber with a through-hole. The through-hole is directly opposite the opening of the focusing groove. The focusing element also includes a light-transmitting plate disposed between the heating chamber and the main body of the element. The light-transmitting plate closes one end of the through-hole, and the heating chamber and the light-transmitting plate form the focusing groove.

[0010] As an optional technical solution for the aerosol generating device, one of the focusing groove and the receiving hole is connected to a mounting groove, the light-transmitting plate is placed in the mounting groove, and the heating chamber is detachably connected to the main body of the component, so that the light-transmitting plate is sandwiched between the heating chamber and the main body of the component.

[0011] As an optional technical solution for the aerosol generation device, the light emitter is a cylindrical bulb, the focusing groove is a bowl-shaped groove, and the reflecting surface is an annular curved surface. Along the direction from the bottom of the focusing groove to the opening of the focusing groove, the curvature of the annular curved surface gradually decreases.

[0012] As an optional technical solution for the aerosol generating device, the light emitter includes a light-emitting part and an assembly part connected together; the main body of the component is also provided with an assembly groove, which is connected to the bottom of the focusing groove; in a plane perpendicular to the depth direction of the focusing groove, the projection of the assembly groove covers the projection of the bottom of the assembly groove, the assembly part is fixedly installed in the assembly groove, and the light-emitting part extends into the focusing groove.

[0013] As an optional technical solution for the aerosol generating device, the end of the light-emitting part away from the assembly part is a convex curved surface, and the end of the assembly part away from the light-emitting part is a circular plane.

[0014] As an optional technical solution for the aerosol generation device, the light emitter is a xenon lamp.

[0015] As an optional technical solution for the aerosol generation device, the xenon lamp has a diameter of 3mm-10mm and a height of 6mm-18mm.

[0016] As an optional technical solution for the aerosol generation device, the light emitter is coaxially arranged with the focusing groove.

[0017] As an optional technical solution for the aerosol generating device, at least one temperature measuring device is also provided in the receiving tank, which is used to monitor the temperature of the bottom of the receiving tank; the aerosol generating device also includes a control module, which is communicatively connected to the temperature measuring device and the light emitter respectively, and the control module can control the output power of the light emitter according to the temperature of the bottom of the receiving tank.

[0018] The beneficial effects of this utility model are:

[0019] This aerosol generation device emits light along the depth of the receiving tank via a bottom-mounted photoheating component, directly acting on the bottom of the aerosol-generated product. This achieves axial, penetrating light energy transfer, directly heating the product from the bottom, thus optimizing the axial heating path and achieving non-contact, rapid heating of the aerosol-generated product. Compared to traditional lateral heating, this method results in lower energy loss, significantly improving the preheating waiting time issues of traditional resistance and induction heating, and accelerating smoke emission. The light emitter provides the light source for the focusing element. The reflective surface, through curved geometry, alters the light path direction, forming a secondary optical system that converts the divergent light into a longitudinally parallel beam after reflection, achieving directional control of the light path. This allows the scattered light to be precisely focused onto the heating area, enabling centralized heat source control, improving heating efficiency, significantly increasing light utilization, and helping to reduce energy loss. Compared to traditional halogen lamp direct irradiation, the photoheating component increases the luminous flux per unit power and reduces energy consumption, thus optimizing the energy efficiency ratio. Furthermore, the photothermal heating method eliminates the need for direct contact with the aerosol-generating product, facilitating a transparent and sealed design. This helps isolate e-liquid residue from contaminating the heating element, avoiding the residue problems associated with traditional resistance heating, and improving cleaning convenience. It solves the cleaning challenges of traditional contact heating. Simultaneously, the bottom light emission path aligns with the insertion direction of the aerosol-generating product, shortening the light energy transmission path and accelerating the smoke emission speed. The insertion design along the depth of the storage slot adapts to the shape of conventional aerosol-generating products, supporting mainstream aerosol-generating products through standardized insertion positioning, thus enhancing product versatility and market compatibility.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figures 1 to 8 As shown, this embodiment provides an aerosol generating device for heating an aerosol generating product 10. The surface of the aerosol generating device is provided with a receiving groove, and the aerosol generating product 10 can be inserted into the receiving groove along the depth direction of the receiving groove. The aerosol generating device includes a light heating component, which includes a light concentrator 30 and a light emitter 40. The light concentrator 30 includes a main body, and a light concentrating groove is provided inside the main body. The opening of the light concentrating groove is perpendicular to the depth direction of the receiving groove. The light emitter 40 is used to emit light and is located inside the light concentrating groove. The side wall of the light concentrating groove includes a reflective surface 32. The reflective surface 32 is used to change the light by reflection so that it propagates along the depth direction of the receiving groove, so that the light enters the receiving groove from the bottom of the receiving groove to irradiate the aerosol generating product 10.

[0040] This aerosol generating device emits light along the depth of the receiving groove through a bottom photoheating component, directly acting on the bottom of the aerosol generating product 10. This achieves axial penetrating light energy transfer, directly heating the bottom of the aerosol generating product 10, thereby optimizing the axial heating path and achieving non-contact rapid heating of the aerosol generating product 10. Compared with traditional lateral heating, it has lower energy loss, significantly improving the preheating waiting problem of traditional resistance heating and induction heating, and accelerating the smoke emission speed. The light emitter 40 provides a light source for the focusing element 30. The reflector 32 changes the light path direction through curved surface geometry design, forming a secondary optical system that converts the divergent light into a longitudinal parallel beam after reflection, achieving directional control of the light path. This allows the scattered light to be precisely focused on the heating area, thereby achieving centralized control of the heat source, improving heating efficiency, significantly increasing light utilization, and helping to reduce energy loss. Compared with the traditional direct irradiation method of halogen lamps, the photoheating component increases the luminous flux per unit power and reduces energy consumption, thus optimizing the energy efficiency ratio. Furthermore, the photothermal heating method eliminates the need for direct contact with the aerosol generating product 10, facilitating a light-transmitting and sealed design. This helps isolate e-liquid residue from contaminating the heating component, avoiding the e-liquid residue problem associated with traditional resistance heating, improving cleaning convenience, and solving the cleaning challenges of traditional contact heating. Simultaneously, the bottom light emission path aligns with the insertion direction of the aerosol generating product 10, shortening the light energy transmission path and accelerating the smoke emission speed of the aerosol generating product 10. The insertion design along the depth of the storage slot adapts to the shape of conventional aerosol generating products 10, supporting mainstream aerosol generating products 10 through standardized insertion positioning, thus improving product versatility and market compatibility.

[0041] In this embodiment, the aerosol generating product 10 is a cylindrical component, with a filter tip 11 at one end and a heating section at the other end. When the aerosol generating device heats the heating section, a cooling section 12 and an aerosol generating medium 14 are sequentially formed in the direction away from the filter tip 11. The aerosol generating medium 14 has a hollow portion 13 at one end near the cooling section 12. The aerosol generating medium 14 can be cylindrical or polygonal, and its composition can be a traditional tobacco medium.

[0042] In this embodiment, the reflective surface 32 needs to undergo processes such as grinding, polishing, and coating to maximize the surface smoothness of the inner surface, thereby increasing the reflection of light on the inner surface of the light-concentrating element 30 and minimizing light loss on the sidewalls. Specifically, the surface roughness Ra of the reflective surface 32 is ≤0.8.

[0043] Furthermore, the aerosol generating device also includes a heating chamber 20, which has a through-hole that faces the opening of the focusing groove. The focusing element 30 also includes a light-transmitting plate 31 located between the heating chamber 20 and the main body of the element. The light-transmitting plate 31 closes one end of the through-hole, and the heating chamber 20 and the light-transmitting plate 31 form a focusing groove.

[0044] By sealing the system interface with the light-transmitting plate 31, the light-transmitting plate 31 can form a barrier to physically isolate the heating chamber 20 and the focusing element 30, effectively preventing e-liquid from seeping into the light heating component and contaminating the reflective surface 32. This maintains the smoothness of the surface of the focusing element 30, ensures stable reflection efficiency, guarantees long-term stability, and achieves optical path sealing. At the same time, the separate structural design of the heating chamber 20 and the focusing element 30 facilitates individual maintenance or replacement of damaged parts, simplifies the cleaning and maintenance process, and helps to achieve modular assembly.

[0045] Specifically, the heating chamber 20 is made of SUS304 stainless steel. The inner cross-sectional dimension of the heating chamber 20 is slightly larger than the cross-sectional dimension of the aerosol generating product 10, and the gap between the inner wall of the heating chamber 20 and the surface of the aerosol generating product 10 serves as an airflow channel.

[0046] Furthermore, one of the light-concentrating groove and the storage hole is connected to a mounting groove, the light-transmitting plate 31 is placed in the mounting groove, and the heating chamber 20 is detachably connected to the main body of the component, so that the light-transmitting plate 31 is sandwiched between the heating chamber 20 and the main body of the component.

[0047] The light-transmitting plate 31 is fixedly embedded in the mounting slot, and together with the threaded locking structure between the heating chamber 20 and the main body, it ensures airtightness and prevents light path deviation, improving equipment reliability and assembly stability. The clamp-on installation of the light-transmitting plate 31 enhances joint sealing through mechanical pressure, preventing e-liquid leakage from the joint. Simultaneously, the detachable connection structure reduces the difficulty of disassembling and assembling the light-transmitting plate 31, facilitating regular cleaning of e-liquid deposits, improving maintenance efficiency, and extending equipment lifespan.

[0048] Furthermore, one of the heating chamber 20 and the main body is provided with an internal thread coaxial with the depth direction of the receiving groove, and the other is provided with an external thread coaxial with the depth direction of the receiving groove, with the internal thread and the external thread engaging.

[0049] The threaded engagement direction is coaxial with the depth direction of the receiving groove, ensuring uniform force on each component during assembly, achieving axial force locking, and guaranteeing the airtightness of the connection between the heating chamber 20 and the focusing element 30, preventing light or air leakage from affecting heating efficiency. The self-centering characteristic of the threaded structure ensures high assembly positioning accuracy, allowing the thread engagement process to automatically correct the coaxiality of the heating chamber 20 and the focusing element 30, ensuring that the light path coincides with the central axis of the aerosol-generating product 10, achieving rapid positioning of the heating chamber 20 and the main body of the product, thereby achieving uniform heating.

[0050] In this embodiment, high-temperature resistant silicone is used at the joint between the heating chamber 20 and the main body to improve sealing.

[0051] In this embodiment, the light emitter 40 is a cylindrical bulb, the focusing groove is a bowl-shaped groove, and the reflecting surface 32 is an annular curved surface. Along the direction from the bottom of the focusing groove to the opening of the focusing groove, the curvature of the annular curved surface gradually decreases.

[0052] The bowl-shaped focusing groove structure matches the cylindrical light-emitting part of the light emitter 40, and the light is focused through the curvature design of the reflective surface 32. The gradually changing curvature design of the annular curved reflective surface 32 ensures that the incident angle of the light is always greater than the critical angle, converting the divergent light from the sidewalls of the light emitter 40 into a parallel beam, significantly improving the reflection efficiency. The coaxial structure ensures uniform energy distribution of the light spot, avoiding local overheating and carbonization of aerosols to form the product 10. Moreover, the geometric parameters of the bowl-shaped focusing groove and the cylindrical light emitter 40 are easy to adjust to match, thereby maximizing the utilization of the light-emitting surface of the light emitter 40 and reducing edge light loss. At the same time, the bowl-shaped structure of the focusing groove and the cylindrical bulb form a convection heat dissipation channel, reducing the operating temperature of the light emitter 40.

[0053] Furthermore, the light emitter 40 is coaxially positioned with the focusing slot. These features optimize the light refraction effect of the light heating component, improve the uniformity of light entering the receiving slot, and contribute to a better user experience for the aerosol generation device.

[0054] Through optical simulation, it is found that under the focusing effect of the focusing element 30 provided in this embodiment, the energy efficiency of the xenon lamp light at the bowl of the focusing element 30 can be increased to at least 60%.

[0055] Furthermore, the light emitter 40 is a xenon lamp.

[0056] Xenon lamps have high luminous efficacy, which reduces the smoke emission time of aerosol-generated products 10 to within 2 seconds, essentially eliminating the need for preheating and improving the photothermal effect. Compared to traditional halogen and incandescent lamps, xenon lamps offer higher luminous efficiency and brightness.

[0057] Specifically, xenon lamps have a diameter of 3mm-10mm and a height of 6mm-18mm; their rated power is 10-30W and their operating voltage is 5-10V.

[0058] In this embodiment, the focusing element 30 is cylindrical in shape, occupying little space, with a high degree of integration, compact structure, and small size, making it suitable for low-temperature heating of the aerosol-generated product 10. The focusing element 30 is made of materials such as aluminum alloy, stainless steel, high-temperature resistant plastic, aluminum alloy plastic, quartz, or borosilicate glass. Its overall shape is cylindrical. The internal structural parameters of the focusing element 30 are determined by the structure of the xenon lamp, and the method of determination is common knowledge in the art and well-known to those skilled in the art, so it will not be elaborated further here.

[0059] For example, the light emitter 40 includes a light-emitting part and an assembly part connected to each other; the main body of the component is also provided with an assembly groove, which is connected to the bottom of the focusing groove; in a plane perpendicular to the depth direction of the focusing groove, the projection of the assembly groove covers the projection of the bottom of the assembly groove, the assembly part is fixedly installed in the assembly groove, and the light-emitting part extends into the focusing groove.

[0060] The design of the assembly slot's projection covering the projection of the slot's bottom ensures that the light-emitting unit is precisely positioned on the axis of the focusing slot. The ceramic assembly fixes the electrode lead 41 to prevent displacement, ensuring optical path consistency. Simultaneously, the snap-fit ​​connection between the assembly slot and the light-emitting unit enhances the aerosol generation device's drop resistance.

[0061] Specifically, the end of the light-emitting part away from the assembly part is a convex curved surface, and the end of the assembly part away from the light-emitting part is a circular flat surface. An electrode lead 41 extends from the bottom and is fixed to a ceramic fixing member 42. The ceramic fixing member 42 is tightly assembled with the lower end of the focusing member 30, thereby achieving the fixed assembly of the xenon lamp within the focusing member 30.

[0062] By defining the surface shape of the light emitter 40, the light-emitting capability of the light-heating component can be optimized, the energy consumption of the aerosol generation device can be reduced, and the efficiency of operation can be improved.

[0063] The high thermal conductivity of ceramic materials can effectively dissipate the heat generated by the xenon lamp, preventing the temperature rise of the focusing element 30 from affecting the performance of the reflector 32 and helping to extend the service life of the light heating assembly. Furthermore, the cooperation between the assembly and the ceramic fixing component 42 forms an axial heat dissipation path, improving the service life of each component in the light heating assembly.

[0064] In this embodiment, at least one temperature measuring device 21 is also provided in the storage tank. The temperature measuring device 21 is used to monitor the temperature of the bottom of the storage tank. The aerosol generating device also includes a control module 50. The control module 50 is communicatively connected to the temperature measuring device 21 and the light emitter 40 respectively. The control module 50 can control the output power of the light emitter 40 according to the temperature of the bottom of the storage tank.

[0065] The temperature measuring device 21 enables the aerosol generating device to automatically adjust the light power output based on the matrix differences (such as tobacco density or humidity) of the aerosol generating product 10, controlling the amount of smoke in the aerosol generating medium 14 and ensuring consistency in smoke volume across different batches of products. By using the temperature measuring device 21 to monitor the heating zone temperature in real time and adjusting the power output accordingly, closed-loop feedback control of the xenon lamp power is achieved. This reduces energy consumption compared to an open-loop system, keeps temperature fluctuations in the heating zone within a small range, and enables power self-adaptation. Furthermore, the combination of the temperature measuring device 21 and the control module 50 facilitates the implementation of an overheat protection mechanism, allowing the power to be immediately cut off when the temperature measuring device 21 detects an abnormal temperature rise, preventing overheating and resulting in a burnt smell, thus improving safety and achieving dynamic temperature control.

[0066] For example, the wall of the receiving tank is provided with at least two positioning structures 22, which are used to abut against the side wall of the aerosol-generated product 10. Specifically, the positioning structures 22 are located at the bottom of the receiving tank.

[0067] At least two positioning structures 22 define the radial position of the aerosol generating product 10, minimizing the center offset of the aerosol generating product 10, ensuring a constant distance between the bottom of the aerosol generating product 10 and the light-transmitting plate 31, guaranteeing heating uniformity, achieving standardized positioning, and reducing cleaning difficulty. Simultaneously, the gap between the support structure and the aerosol generating product 10 forms a uniform longitudinal airflow channel, optimizing the aerosol flow path, reducing suction resistance, and improving the smoothness of smoke output.

[0068] In this embodiment, the aerosol generating device further includes a battery system 60, which is electrically connected to the photoheating component and is used to supply power to the photoheating component.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
