Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and particularly relates to a heater for heating an aerosol forming matrix and a low-temperature electronic atomization device. Background Technology

[0002] Currently available non-combustible low-temperature electronic atomization devices work by heating the aerosol-forming matrix at low temperatures to generate an aerosol. Because the heaters in these devices typically operate at low temperatures, the aerosol-forming matrix is ​​simply baked and distilled without burning, effectively reducing the formation of harmful substances. Furthermore, the absence of an open flame lowers safety concerns.

[0003] In practical applications, aerosol forming matrix (ACM) is typically shaped into strips. During use, these strips are inserted into the heater of a cryogenic electronic atomization device. The heater primarily heats and bakes the ends of the ACM strip. It is evident that this existing heating method has extremely limited heat transfer efficiency and is prone to causing concentrated heating, resulting in uneven heating.

[0004] To address the issue of uneven heating, existing technologies employ a cylindrical heating element that surrounds the inserted aerosol-forming matrix, providing circumferential heating. While this results in relatively uniform circumferential heating, the heating rate is slow, impacting usability. Summary of the Invention

[0005] The purpose of this application is to provide a heater and a low-temperature electronic atomizing device to solve the technical problems of uneven heating and slow heating speed in the prior art low-temperature electronic atomizing devices.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide a heater, comprising:

[0008] The heating element has a heating cavity for containing the aerosol forming matrix and circumferentially heating the aerosol forming matrix;

[0009] A photothermal assembly includes a lamp and a lens. The lamp is disposed at one end of the heating chamber, and the aerosol forming matrix is ​​inserted into the heating tube from the other end of the heating chamber. The lens is located between the lamp and the heating tube. The lamp is used to generate light and heat the aerosol forming matrix through the lens.

[0010] In this way, the heating tube and the photothermal component heat the inserted aerosol forming matrix circumferentially and end-point, respectively. The main and auxiliary heating of the two components can be combined to fully heat the aerosol forming matrix while avoiding scorching caused by concentrated heating, thus effectively improving the heating uniformity and efficiency of the aerosol forming matrix.

[0011] The structure of the heating tube is improved so that it is a light-transmitting tube with a hollow interlayer within its circumferential wall. A heating element is housed within this interlayer, which generates light during operation and transmits it through the wall of the heating tube to heat the aerosol-forming matrix. Thus, because this light can directly act on the outer periphery of the aerosol-forming matrix, the energy transfer medium is reduced, effectively improving the circumferential heating efficiency of the aerosol-forming matrix.

[0012] In one embodiment, the circumferential wall of the heating tube has an inner wall located inside the heating tube and an outer wall located outside the heating tube, and the interlayer is formed between the inner wall and the outer wall; wherein, the outer wall has a light-shielding layer made of a low emissivity material, which helps to prevent the light emitted by the heating element in the glass heating tube interlayer from easily escaping outward.

[0013] In one embodiment, the heating element is provided on the heating tube, and the heating element is used to generate heat by passing electricity to heat the aerosol forming matrix.

[0014] The heater structure is improved by further including a fixing bracket comprising an upper cover and a bottom cover. The outer periphery of the upper cover has a surrounding wall extending to the outer edge of the bottom cover. The heating element and the photothermal assembly are disposed between the upper cover and the bottom cover and within the surrounding wall. This allows the heating element to surround the outer periphery of the aerosol-forming matrix inserted into the heater, and the photothermal assembly to be positioned at the end of the aerosol-forming matrix. This enables both circumferential heating of the inserted aerosol-forming matrix and concentrated heating of its end, effectively improving heating uniformity and efficiency.

[0015] In one embodiment, the mounting bracket further includes a connecting ring and a lampshade. The upper cover has a first fixing ring for inserting the aerosol forming matrix, and the bottom cover has a second fixing ring corresponding to the position of the first fixing ring. Both ends of the heating element are fixed to the first fixing ring and the connecting ring, respectively. Both ends of the lampshade are connected to the connecting ring and the second fixing ring, respectively. The connecting ring communicates with the lampshade, the lens is disposed within the connecting ring, and the luminaire is housed within the lampshade. This locks the installation positions of the heating element, lens, and luminaire, and positions the lens between the end of the aerosol forming matrix and the luminaire. The lampshade outside the luminaire serves both to house the luminaire and to prevent light loss during operation.

[0016] The structure of the lampshade is improved. The lampshade includes an upper cover and a lower cover, which are detachably connected. There is a heat insulation gap between the outer periphery of the lampshade and the wall of the upper cover, which helps to reduce the outward diffusion of heat and effectively reduce the temperature of the heater on the low-temperature electronic atomizer, thereby improving the user experience.

[0017] In one embodiment, the upper cover has a protruding ring for extending into the connecting ring, and the lens rests on the opening of the protruding ring. This facilitates locking the lens's mirror orientation and improves the lens's positioning effect.

[0018] In one embodiment, the lower housing has a mounting base for mounting the lamp, the mounting base having a positioning groove and a wire outlet hole at the bottom of the positioning groove, and the bottom cover having an opening communicating with the wire outlet hole; the lamp is disposed in the positioning groove of the mounting base, and the electrodes of the lamp pass through the wire outlet hole and the opening of the bottom cover in sequence and extend out of the heater. By positioning the lamp in the positioning groove of the mounting base, a gap is left between the outer periphery of the lamp and the inner wall of the lamp cover to ensure the brightness of the light produced when the lamp is working.

[0019] Secondly, this application also provides a low-temperature electronic atomization device, including a housing, a power supply component, and the aforementioned heater. Both the heater and the power supply component are disposed within the housing. The power supply component includes a circuit board and a battery that supplies power to the heater. The heater and the battery are respectively disposed on opposite sides of the circuit board. The battery, the heating element on the heater, and the lamp are electrically connected to the circuit board. This allows for balanced weight distribution in the low-temperature electronic atomization device and improves the compactness of the components, thus reducing the overall size. Furthermore, the heater and battery are located on opposite sides of the vertically arranged circuit board, which helps to shorten the connection path of the electrical cables.

[0020] The beneficial effects of the heater and cryogenic electronic atomization device provided in this application are as follows: Compared with the prior art, the heater structure in the cryogenic electronic atomization device is improved. The heater includes a heating tube and a light heating component. The heating tube forms a heating cavity for accommodating the aerosol-forming matrix and circumferentially heats the aerosol-forming matrix, resulting in uniform heating. The light heating component includes a lamp and a lens. The lamp is located at one end of the heating cavity, and the aerosol-forming matrix can be inserted into the heating tube from the other end of the heating cavity. The lens is located between the lamp and the heating tube. The light generated when the lamp is working is transmitted through the lens to concentrate the heating of the aerosol-forming matrix. Since this light acts directly on the aerosol-forming matrix, the energy transfer medium is reduced, resulting in faster heating and thus improved heating efficiency.

[0021] Because the heating element and the light heating component are independently configured heating parts, combined application of heating modes is possible. By using the heating element and the lamp as primary and secondary heating elements respectively, the aerosol forming matrix can be heated sufficiently while avoiding scorching caused by concentrated heating, effectively improving the heating uniformity and efficiency of the aerosol forming matrix.

[0047] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0048] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] In practical applications, aerosol forming matrix is ​​typically formed into strips. During use, these strips of aerosol forming matrix are inserted into the heater of a cryogenic electronic atomization device. The heater primarily heats and bakes the ends of the aerosol forming matrix. It is evident that traditional heating methods have extremely limited heat transfer efficiency and are prone to causing concentrated heating, resulting in uneven heating.

[0052] In related technologies, there are structures that use cylindrical heating tubes to cover the outer periphery of an inserted aerosol matrix for heating. Although circumferential heating is relatively uniform, the heating speed is slow, affecting the performance.

[0053] Therefore, this application provides a novel heater and a low-temperature electronic atomization device. The structure of the heater is redesigned, and the aerosol forming matrix is ​​heated by irradiation with light. A structure combining centralized heating and circumferential heating is adopted to improve the uniformity of heating and the heating efficiency. This effectively solves the technical problems of uneven heating and slow heating speed in the existing low-temperature electronic atomization devices. The invention will now be described in detail.

[0054] Please refer to the following: Figure 1 , Figure 2 and Figure 3 A cryogenic electronic atomizing device includes a housing 100, a power supply component 200, and a heater 300 provided in the embodiments of this application. The heater 300 forms a heating region M on the cryogenic electronic atomizing device for heating an inserted aerosol forming matrix 400.

[0055] The heater 300 includes a heating tube 1 disposed in the heating region M and forming a heating cavity for accommodating the aerosol forming matrix 400. The heating tube 1 can adopt a conventional metal tube structure, with a heating wire disposed on the metal tube and the heating wire used to heat the metal tube. The heat reaches the outer periphery of the aerosol forming matrix 400 covered by the metal tube through the metal tube, thereby achieving circumferential heating of the aerosol forming matrix 400.

[0056] The heater 300 also includes a light heating assembly for heating the end of the inserted aerosol forming matrix 400. The light heating assembly includes a lamp 2 and a lens 3. The lamp 2 is disposed at one end of the heating chamber, and the aerosol forming matrix can be inserted into the heating tube 1 from the other end of the heating chamber. The lens 3 is located between the lamp 2 and the heating tube 1.

[0057] As can be seen, when the aerosol forming matrix 400 is inserted into the low-temperature electronic atomization device, the insertion portion of the aerosol forming matrix 400 is located in the aforementioned heating region M and within the heating tube 1, with the heating tube 1 covering the outer periphery of the insertion portion of the aerosol forming matrix 400. Simultaneously, the lens 3 is located between the lamp 2 and the heating tube 1, with the mirror surface of the lens 3 facing the end of the aerosol forming matrix 400. This can be understood as the end of the insertion portion of the aerosol forming matrix 400 being positioned close to the lens 3, or directly in contact with the mirror surface of the lens 3. The lens 3 can also be used to limit the insertion stroke of the aerosol forming matrix 400.

[0058] The lamp 2 is connected to the power supply component 200 of the low-temperature electronic atomization device. When the lamp 2 is working, it can generate light, which passes through the lens 3 to heat and bake the end of the aerosol forming matrix 400. It can be seen that since this light acts directly on the aerosol forming matrix 400, the energy transfer medium is reduced, thus making the heating speed faster.

[0059] In the heater 300 provided in this embodiment, the heating element 1 heats the inserted aerosol forming matrix 400 circumferentially, while the photothermal component heats the inserted aerosol forming matrix 400 at its end. Both are independently configured. This means at least three heating modes are possible: heating by the heating element 1 alone, heating by the photothermal component alone, and simultaneous heating by the heating element 1 and the photothermal component. Therefore, a better heating effect can be achieved by combining these heating modes.

[0060] As an example, in a common use case, heating of the aerosol forming matrix 400 has at least two stages, including a preheating stage and a usage stage.

[0061] During the preheating phase, lamp 2 operates and emits light, which, through lens 3, concentrates heat on the end of the inserted aerosol forming matrix 400. Because the light heating acts directly on the aerosol forming matrix 400, aerosols can be rapidly generated at the end of the aerosol forming matrix 400. At this time, heating element 1 acts as auxiliary heating, circumferentially heating the outer periphery of the aerosol forming matrix 400, thus preventing condensation of the aerosol during output.

[0062] During the usage phase, i.e., after the preheating phase described above, the temperature of heating element 1 is increased for primary heating, while the heating temperature of lamp 2 is lowered for auxiliary heating. This effectively avoids the situation where only the end of the aerosol forming matrix 400 is heated, which could easily lead to scorching, and improves the uniformity of heating of the aerosol forming matrix 400. This is conducive to fully heating the aerosol forming matrix 400, thereby improving heating efficiency.

[0063] Compared with the prior art, the heater 300 provided in this embodiment improves the structure of the heater 300 in the low-temperature electronic atomization device. The heater 300 includes a heating tube 1 and a light heating assembly. The heating tube 1 forms a heating cavity for accommodating the aerosol forming matrix 400 and circumferentially heats the aerosol forming matrix 400, resulting in uniform heating of the aerosol forming matrix 400. The light heating assembly includes a lamp 2 and a lens 3. The lamp 2 is disposed at one end of the heating cavity, and the aerosol forming matrix can be inserted into the heating tube 1 from the other end of the heating cavity. The lens 3 is located between the lamp 2 and the heating tube 1. The light generated when the lamp 2 is working is transmitted through the lens 3 to concentrate the heating of the aerosol forming matrix 400. Since this light acts directly on the aerosol forming matrix 400, the energy transfer medium is reduced, resulting in faster heating and improved heating efficiency.

[0064] In practical applications, since the heating element 1 and the light heating component are independently set heating parts, a combination of heating modes can be achieved. Specifically, the heating element 1 and the lamp 2 can be used as main and auxiliary heating elements in an alternating combination, which can not only fully heat the aerosol forming matrix 400, but also avoid the burning caused by concentrated heating, effectively improving the heating uniformity and heating efficiency of the aerosol forming matrix 400.

[0065] Regarding the structure of heating element 1, it is typically made of a metal tube with the heating wire mounted on it. The metal tube serves as the heat transfer medium for heating the aerosol forming matrix 400 after the heating wire is heated. This direct physical contact heating method can easily burn the aerosol forming matrix 400. Furthermore, due to mass production in factories, the surface texture of the aerosol forming matrix 400 is uncontrollable, often resulting in unevenness. The concave areas cannot maintain stable contact with the surface of the metal tube, affecting heat conduction and thus the uniformity of heating on the entire outer surface of the aerosol forming matrix 400.

[0066] Therefore, in order to improve the heating effect on the outer periphery of the inserted aerosol forming matrix 400, please refer to one embodiment of this application. Figure 4 The heating tube 1 is preferably a light-transmitting tube, and the glass circumferential wall of the heating tube 1 has a hollow interlayer 10. A heating element 4 is disposed in the hollow interlayer 10 of the heating tube 1. The heating element 4 can preferably be a heating wire, which can preferably be made of tungsten, stainless steel or other materials, which helps to improve the shape plasticity of the heating element 4, so that the heating element 4 can be disposed in the glass heating tube 1 interlayer 10.

[0067] In practical applications, at least a portion of the heating element 4 extends from the interlayer 10 to be electrically connected to the power supply assembly 200 of the low-temperature electronic atomization device. When the heating element 4 is working, it generates light that can be uniformly irradiated onto the outer periphery of the aerosol forming matrix 400 covered by the heating tube 1 through the wall surface of the heating tube 1, thereby photoheating the aerosol forming matrix 400.

[0068] This reduces the heat transfer medium between the heating element 4 and the aerosol forming matrix 400. This means that the light can directly act on the aerosol forming matrix 400 without being restricted by the contact condition between the heat transfer medium and the aerosol forming matrix 400, effectively improving the uniformity of circumferential heating of the aerosol forming matrix 400 and thus improving the heating efficiency.

[0069] Regarding the structure of the heating element 4 within the glass heating tube 1 interlayer 10, please refer to one embodiment of this application. Figure 5The heating element 4 may include multiple heating wires, which are arranged in an orderly manner in the interlayer 10 of the heating tube 1 and electrically connected to the power supply component 200 of the low-temperature electronic atomization device.

[0070] As an example, in this embodiment, an upper heating wire 41 and a lower heating wire 42 are disposed within the interlayer 10 of the glass heating tube 1. The upper heating wire 41 and the lower heating wire 42 are adjacent to each other, which helps to cover the entire circumferential wall of the heating tube 1. The upper heating wire 41 and the lower heating wire 42 are two independent parts and are electrically connected to the power supply component 200 of the low-temperature electronic atomization device, respectively. The upper heating wire 41 and the lower heating wire 42 can be controlled to generate light independently.

[0071] Therefore, the heating element 4 can be composed of multiple heating wires and heated separately, enabling different heating combinations, effectively improving the flexibility of use, and further improving the heating performance of the heater 300.

[0072] For the specific structure of the circumferential wall of the glass heating tube 1, please refer to one embodiment of this application. Figure 4 The circumferential wall of the glass heating tube 1 has an inner wall 11 located inside the heating tube 1 and an outer wall 12 located outside the heating tube 1, and a sandwich 10 is formed between the inner wall 11 and the outer wall 12.

[0073] The outer wall 12 has a light-shielding layer made of a low-emissivity material (not shown). In this embodiment, the light-shielding layer is preferably a layer of low-emissivity material, such as aluminum plating or silver, sprayed onto the outer wall 12 of the glass heating tube 1, which helps to prevent the light emitted by the heating element 4 in the interlayer 10 of the glass heating tube 1 from easily escaping.

[0074] Regarding the internal structure of the glass heating tube 1 interlayer 10, in one embodiment of this application, the glass heating tube 1 interlayer 10 can preferably be a vacuum layer, which is beneficial to remove other impurities, thereby ensuring the brightness of the light emitted by the heating element 4 after heating in the interlayer 10, and preventing the heating element 4 from easily oxidizing.

[0075] In another embodiment of this application, the interlayer 10 of the glass heating tube 1 can preferably be a halogen layer with added halogen. The addition of halogen allows the heating element 4, such as a tungsten filament, to react with the halogen element to form a halide when heated, thereby realizing the regeneration process of the tungsten filament.

[0076] In this way, by utilizing the regeneration effect of halogen, the heating element 4 can operate at a higher temperature, which is beneficial for emitting brighter light; and, since the evaporation of the heating element 4, such as the tungsten wire, is reduced, it is beneficial for extending the service life of the heating element 4.

[0077] Regarding the structure of the heating element, in another embodiment of this application (not shown), the material of the heating element 1 can preferably be ceramic or a metal tube. A heating element (not shown) is provided on the heating element 1, which can preferably be a conductive coating, a heating film, a metal sheet, a metal wire, an infrared heating coating, or an electromagnetic induction heating element. Thus, heat is generated by energizing the heating element to heat the aerosol forming matrix.

[0078] For the internal structure of the heater 300, please refer to one embodiment of this application. Figure 6 and Figure 7 The heater 300 also includes a fixing bracket 301, which includes an upper cover 5 and a bottom cover 6. The outer periphery of the upper cover 5 has a surrounding wall 51 extending to the outer edge of the bottom cover 6. The heating tube 1 and the light heating assembly are disposed between the upper cover 5 and the bottom cover 6 and are located within the surrounding wall 51.

[0079] In this way, the heating element 1 can surround the outer periphery of the aerosol forming matrix 400 inserted into the heater 300, and the photoheating component can be set at the end of the aerosol forming matrix 400. This allows for both circumferential heating of the inserted aerosol forming matrix 400 and concentrated heating of the end of the aerosol forming matrix 400. The combination of these two methods effectively improves heating uniformity and heating efficiency.

[0080] Based on the above, please refer to one embodiment of this application as well. Figure 6 and Figure 7 The mounting bracket 301 also includes a connecting ring 7 and a lampshade 8. The upper cover 5 has a first fixing ring 52 for inserting the aerosol forming matrix 400, and the bottom cover 6 has a second fixing ring 61 corresponding to the position of the first fixing ring 52. The two ends of the heating tube 1 are respectively fixed to the first fixing ring 52 and the connecting ring 7, and the two ends of the lampshade 8 are respectively connected to the connecting ring 7 and the second fixing ring 61, so that the heating tube 1 and the light heating component are sequentially connected within the mounting bracket 301.

[0081] The connecting ring 7 is connected to the lamp cover 8, the lens 3 is disposed inside the connecting ring 7, and the lamp 2 is housed inside the lamp cover 8. When the lamp 2 is working, it emits light, which can be irradiated by the lens 3 onto the end of the aerosol forming matrix 400 inserted into the heating tube 1 and concentrated for heating.

[0082] In this way, the installation positions of the heating element 1, lens 3, and lamp 2 are locked, and the lens 3 is positioned between the end of the aerosol forming matrix 400 and the lamp 2. The lamp cover 8 outside the lamp 2 serves both to house the lamp 2 and to prevent the light emitted by the lamp 2 from being lost during operation. The light emitted by the lamp 2 is mainly output from the connection between the lamp cover 8 and the connecting ring 7, and shines through the lens 3 onto the end of the aerosol forming matrix 400.

[0083] Preferably, in this embodiment, such as Figure 6 As shown, both the first fixing ring 52 and the connecting ring 7 are provided with support steps 302. The two ends of the heating tube 1 are respectively inserted into the first fixing ring 52 and the connecting ring 7, and respectively abut against the support steps 302 in the first fixing ring 52 and the connecting ring 7, thereby locking the installation position of the heating tube 1.

[0084] In the embodiments of this application, such as Figure 8 As shown, the housing 100 of the low-temperature electronic atomization device has an insertion port 101 that can be connected to the heater 300. During use, the aerosol forming matrix 400 can be inserted into the heater 300 through the insertion port 101 for heating.

[0085] Preferably, please refer to the following: Figure 6 , Figure 7 and Figure 8 The upper cover 5 also has an outwardly extending guide ring 53, which communicates with the first fixing ring 52 inside the upper cover 5, and the outwardly extending end of the guide ring 53 corresponds to the position of the insertion port 101 on the outer shell 100. The aerosol forming matrix 400 can extend into the outer shell 100 through the insertion port 101, enter the first fixing ring 52 along the guide ring 53, and be inserted into the heating tube 1. Preferably, the inner wall of the guide ring 53 is gradually expanded outward to form a flared mouth, which helps to correct the insertion path of the aerosol forming matrix 400, allowing the aerosol forming matrix 400 to slide smoothly into the heating tube 1, thereby improving the installation efficiency of the aerosol forming matrix 400.

[0086] Preferably, in this embodiment, such as Figure 6 As shown, a plurality of protrusions 521 extending inward are provided within the first fixing ring 52 of the upper cover 5. This can be understood as the plurality of protrusions 521 extending towards the center of the first fixing ring 52. These protrusions 521 abut against the aerosol forming substrate 400 inserted into the heater 300. In this way, the plurality of protrusions 521 within the first fixing ring 52 correct the insertion posture of the aerosol forming substrate 400, thereby improving the concentricity between the inserted aerosol forming substrate 400 and the heating element 1.

[0087] For the specific structure of the lampshade 8, please refer to one embodiment of this application. Figure 9 and Figure 10 The lamp cover 8 includes an upper cover 81 and a lower cover 82. The upper cover 81 and the lower cover 82 are detachably connected, which helps to simplify the disassembly and assembly of the lamp 2 and facilitates the maintenance and replacement of the lamp 2.

[0088] Among them, a heat insulation gap is provided between the outer periphery of the lamp cover 8 and the wall 51 of the upper cover 5 to prevent the light and heat generated by the lamp 2 during operation from being directly transferred to the heater 300, or even to the outside of the entire low-temperature electronic atomization device.

[0089] Thus, a heat-insulating gap is formed between the outer periphery of the lampshade 8 and the surrounding wall 51 of the upper cover 5, which helps to reduce the outward diffusion of the heat generation temperature and effectively reduce the temperature of the heater 300 on the low-temperature electronic atomizer, thereby improving the user experience.

[0090] In this embodiment, please refer to Figure 9 The upper cover 81 has a protruding ring 811 for extending into the connecting ring 7, and the lens 3 rests on the opening of the protruding ring 811.

[0091] The lens 3 can preferably be a convex lens 3 that protrudes towards the lamp 2. The convex ring 811 on the upper cover 81 matches the convex contour of the lens 3, so that the lens 3 can be positioned on the convex ring 811 located inside the connecting ring 7 and the mirror surface orientation of the lens 3 is locked, thereby improving the positioning effect of the lens 3.

[0092] Please refer to the following: Figure 9 and Figure 10 The second fixing ring 61 is a ring protruding on the bottom cover 6. The lower cover 82 of the lampshade 8 is sleeved on the outside of the second fixing ring 61, which helps to improve the sealing performance.
