Description

Technical Field

[0001] This application belongs to the technical field of aerosol forming apparatus, and more specifically, relates to a heating component and a heated non-combustible atomizing device. Background Technology

[0002] Compared to traditional atomizing devices, heated non-combustible devices can directly heat the atomizing substrate using a heating element to generate an aerosol that can be inhaled by the user. Existing heated non-combustible devices have relatively simple heating element structures, typically only able to heat the bottom or periphery of the atomizing substrate, leading to uneven heating of the substrate.

[0003] Taking bottom heating as an example, heat is gradually conducted upwards from the bottom. Due to differences in the transmission distance and the properties of the medium, there is a significant difference in the amount of heat received by the upper and lower parts of the atomizing matrix. This results in insufficient heating at the top and overheating at the bottom, severely affecting the taste of the aerosol. Similarly, during peripheral heating, the parts closer to the heating element are heated first and at a higher temperature, while the parts farther away from the heating element are underheated, leading to lower heating efficiency.

[0053] In the embodiments of this application, a heating component 10 and a heated non-combustible atomizing device are provided. Those skilled in the art will understand that the heating component 10 is a key component within the heated non-combustible atomizing device, used to provide heat to the item to be heated, so that the item to be heated (i.e., the atomizing matrix 20) can be heated to form an aerosol.

[0054] It should be noted that "atomizing matrix 20" refers to a product capable of forming an aerosol. The aerosol may contain volatile compounds. Atomizing matrix 20 can be solid or liquid.

[0055] Those skilled in the art will understand that the atomizing matrix 20 can be a rod-shaped structure; please refer to the appendix. Figures 1-10 Besides the rod-shaped structure shown in the attached figure, the atomizing matrix 20 can also have other structures. For example, the atomizing matrix 20 to be heated can be a rod-shaped structure prepared from a solid material, or it can be a cotton structure that adsorbs a certain amount of aerosol to form a matrix.

[0056] It should be noted that a "heat-not-burn atomizing device" refers to a device that uses low-temperature heating technology to heat an atomizing matrix 20 containing specific components to a suitable temperature, causing the corresponding components in the atomizing matrix 20 to atomize and form an inhalable aerosol. When in operation, this device can generate an aerosol containing specific components without producing an open flame, making it convenient for the user to inhale. Inhalation refers to the situation where the aerosol is inhaled into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

[0057] Please see Figures 1-10 In a first aspect, embodiments of this application provide a heating component 10, which is used at least to heat an atomizing matrix 20 to generate an aerosol from the atomizing matrix 20.

[0058] Specifically, the heating component 10 mainly includes two parts: a heat-conducting component 1 and a heating component 2. The heating component 2 can heat the heat-conducting component 1 when energized. The heat-conducting component 1 itself has good thermal conductivity, so it can heat the atomized matrix 20 fixed on it.

[0059] The heat-conducting component 1 is used to fix and heat the atomizing matrix 20. The heat-conducting component 1 provided in this embodiment includes a first heat conductor 11 and a second heat conductor 12 connected together, wherein the second heat conductor 12 and the heating component 2 are respectively located on both sides of the first heat conductor 11 in the thickness direction, the atomizing matrix 20 and the second heat conductor 12 are located on the same side of the first heat conductor 11, and at this time the atomizing matrix 20 can be fixedly connected to the heat-conducting component 1 through the second heat conductor 12.

[0060] In the heating assembly 10 provided in this embodiment, the heat-conducting component 1 includes a first heat conductor 11 and a second heat conductor 12 connected together, with the second heat conductor 12 and the atomizing matrix 20 located on the same side of the first heat conductor 11. This effectively increases the contact area between the heat-conducting component 1 and the atomizing matrix 20. Under the heat provided by the heating component 2, the first heat conductor 11 and the second heat conductor 12 can simultaneously contact the atomizing matrix 20 and heat it, thereby improving the problem of uneven heating of the atomizing matrix 20 by the heating element and increasing the heating efficiency of the heating element.

[0061] When the heating component 2 heats the heat-conducting component 1, both the first heat conductor 11 and the second heat conductor 12 can be heated. When the atomizing matrix 20 fixed in the heat-conducting component 1 simultaneously contacts the first heat conductor 11 and the second heat conductor 12, different positions of the atomizing matrix 20 can be heated simultaneously. Therefore, it can effectively overcome the defect of uneven heating of the atomizing matrix 20 during use of traditional equipment. At the same time, simultaneous heating of multiple positions also helps to improve the heating efficiency of the heating component 10, thereby providing a better heating effect and ultimately improving the user experience.

[0062] It should be noted that the above-mentioned heat-conducting component 1 is an integral structure, and the first heat conductor 11 and the second heat conductor 12 are integrally formed and made of the same material.

[0063] Specifically, the heat-conducting component 1 can be made of a material with good thermal conductivity, which can be a metallic material or a non-metallic material. For example, the material that can be used for the heat-conducting component 1 includes at least one of metallic silver and metallic copper.

[0064] For details, please refer to Figure 1 and Figure 2 In this embodiment, the heat-conducting component 1 is a hollow tubular structure with one open end. The first heat-conducting body 11 is located at one end of the tubular structure axially close to the heating component 2. The second heat-conducting body 12 includes a peripheral heat-conducting body 121, which is connected to the circumferential outer edge of the first heat-conducting body 11 and extends axially toward the end away from the heating component 2, so as to form a receiving chamber between the second heat-conducting body 12 and the first heat-conducting body 11 that can accommodate the atomized matrix 20.

[0065] Of course, the heat-conducting component 1 can also be other hollow columnar structures, such as triangular prisms, elliptical cylinders, etc. Its shape can be adapted to the shape of the atomizing matrix 20 to be heated. In this embodiment, the atomizing matrix 20 is a cylindrical structure as an example for illustration.

[0066] When the heat-conducting component 1 is heated, the first heat conductor 11 can contact the bottom surface of the atomizing matrix 20 in the axial direction and heat the bottom surface of the atomizing matrix 20, and the peripheral heat conductor 121 can contact the outer wall surface of the atomizing matrix 20 in the circumferential direction and heat the outer wall surface of the atomizing matrix 20.

[0067] Specifically, along the axial direction of the heat-conducting member 1, the orthographic projection of the peripheral heat-conducting body 121 onto the first heat-conducting body 11 is a ring structure. Please refer to [link / reference]. Figure 2 .

[0068] To further improve the connection strength between the atomizing matrix 20 and the heat-conducting member 1 within the receiving chamber, in some embodiments, the heating assembly 10 further includes a sealing ring 6. The sealing ring 6 is located at the end of the heat-conducting member 1 axially away from the heating member 2 and is used to fix it to the atomizing matrix 20 to further confine the atomizing matrix 20 within the receiving chamber. The sealing ring 6 can be an annular structure made of materials such as silicone.

[0069] Please see Figure 1 The sealing ring 6 is fitted around the atomizing substrate 20 and is press-fitted with the atomizing substrate 20. At this time, the sealing ring 6 is press-fitted with the outer wall of the atomizing substrate 20 and can contact the end of the peripheral heat conductor 121 that is away from the first heat conductor 11; of course, a certain distance can also be maintained.

[0070] Of course, to facilitate user inhalation, a filter 30 is also provided at the end of the atomizing matrix 20 away from the heating element 2. The filter 30 can be used to filter out impurities in the obtained aerosol that affect the user's inhalation experience. The user can inhale the heated aerosol through the filter 30. The aforementioned sealing ring 6 can also be fitted onto the outer peripheral sidewall of the filter 30 and press-fitted with the filter 30.

[0071] Please see Figure 1 and Figure 2 When the atomizing matrix 20 is fixed in the heat-conducting component 1 by the sealing ring 6 and the peripheral heat conductor 121, the heat-conducting component 1 can heat the bottom surface and the outer peripheral surface of the atomizing matrix 20 simultaneously through the first heat conductor 11 and the peripheral heat conductor 121, so as to effectively improve the heating efficiency, improve the problem of overheating and underheating of some parts of the atomizing matrix 20 due to uneven heating, and also help to improve the taste of the aerosol generated by the heating of the atomizing matrix 20.

[0072] Please note that you should refer to [link / reference]. Figure 1 The heating component 2 includes a laser irradiation section 21, at least a portion of which is located on the side of the first heat conductor 11 facing away from the second heat conductor 12, for heating the first heat conductor 11.

[0073] The laser irradiation unit 21 is used to emit laser light towards the first heat conductor 11. For the direction and path of the laser emitted by the laser irradiation unit 21, please refer to [link / reference needed]. Figure 1 Arrow. When the laser irradiates the surface of the first heat conductor 11, the free electrons within the first heat conductor 11 can absorb photon energy and be excited, ultimately causing the surface temperature of the first heat conductor 11 to rise. During this process, energy rapidly diffuses from the surface of the first heat conductor 11 to its interior, thereby gradually increasing the temperature inside the first heat conductor 11 and at the second heat conductor 12. Ultimately, both the first heat conductor 11 and the second heat conductor 12 are heated under the action of the laser irradiation unit 21, and work together to achieve the common heating of the atomized matrix 20.

[0074] Compared to other heating methods, laser heating can achieve precise temperature control by utilizing the high energy density and focusing performance of lasers.

[0075] To improve the absorption efficiency of laser energy by the heat-conducting component 1, in some embodiments, the surface of the first heat conductor 11 facing the laser irradiation part 21 can be roughened, for example by sandblasting or etching, to increase the surface roughness of the first heat conductor 11, thereby disrupting specular reflection and increasing the path of light on the surface of the first heat conductor 11, allowing more laser energy to be absorbed. Alternatively, a coating can be applied to the surface of the first heat conductor 11 facing the laser irradiation part 21, such as a black coating or a carbon-based coating. These coatings have high absorption rates at specific wavelengths and may alter the optical properties of the surface, such as increasing absorption and reducing reflection. Alternatively, the surface of the first heat conductor 11, made of metallic material, facing the laser irradiation part 21 can be oxidized, for example, to form an oxide film. The absorption rate of oxides is generally higher than that of the metal itself. Of course, other processing methods disclosed in related technologies can also be used, and this embodiment does not limit them.

[0076] Of course, the heating component 2 in this embodiment may also include other heating structures. Other heating structures may directly heat the first heat conductor 11 or directly heat the end of the second heat conductor 12 away from the first heat conductor 11. This embodiment does not limit them. In addition, other heating structures may use laser heating or other heating methods, such as electromagnetic heating, microwave heating, infrared radiation heating, and electric field heating, as long as rapid heating can be achieved.

[0077] Please see Figure 1 and Figure 2 In this embodiment, the heating assembly 10 further includes a temperature measuring component 3 and a temperature control component 4 connected together. The temperature measuring component 3 is connected to the heat conducting component 1 and is used to acquire the temperature of the heat conducting component 1 and output a temperature signal. The temperature control component 4 is connected to both the temperature measuring component 3 and the heating assembly 2. The temperature control component 4 is used to respond to the temperature signal output by the temperature measuring component 3 and control the irradiation energy density of the laser irradiation part 21 in the heating assembly 2 acting on the surface of the first heat conductor 11.

[0078] Of course, the heating assembly 10 also includes a power supply 7 connected to the temperature control component 4. The power supply 7 is used to supply power to the temperature sensing component 3 and the temperature control component 4.

[0079] Please see Figure 1 In this embodiment, the temperature control component 4 can adjust the irradiation energy density of the laser irradiation unit 21 acting on the surface of the first heat conductor 11 by directly adjusting the output power of the laser irradiation unit 21.

[0080] Specifically, in response to the temperature signal, the temperature control component 4 can generate a control signal and output the control signal to the laser irradiation unit 21 to change the irradiation energy density of the laser irradiation unit 21 acting on the surface of the first heat conductor 11, and ultimately adjust the heating power applied by the laser irradiation unit 21 to the heat conductor 1.

[0081] Specifically, the laser irradiation unit 21 can change its output power according to the control signal output by the temperature control component 4. The change method includes increasing the output power or decreasing the output power.

[0082] Please see Figure 1 The temperature control component 4 includes a controller 41 electrically connected to the laser irradiation unit 21. The controller 41 is used to adjust the output power of the laser irradiation unit 21 according to the detection result (i.e., the output temperature signal) of the temperature measuring component 3.

[0083] When the laser irradiation unit 21 is in the on state, if the temperature signal output by the temperature measuring component 3 is lower than the preset value or the preset range value, it indicates that the heating temperature is off, and the controller 41 can increase the output power of the laser irradiation unit 21; if the temperature signal output by the temperature measuring component 3 is higher than the preset value or the preset range value, it indicates that the heating temperature is too high, and the controller 41 can decrease the output power of the laser irradiation unit 21; if the temperature signal output by the temperature measuring component 3 is equal to the preset value or falls within the preset range value, it indicates that the heating temperature meets the requirements, and the controller 41 does not output an adjustment signal to control the laser irradiation unit 21 to change its working state.

[0084] The above preset values ​​and preset range values ​​can be adjusted adaptively according to equipment requirements, and this embodiment does not limit them.

[0085] In some embodiments, the temperature sensing component 3 includes a thermocouple temperature sensor. Using a thermocouple temperature sensor for temperature detection is a known technique in the art.

[0086] To improve the temperature measurement accuracy of the temperature sensing component 3, in some embodiments, at least two thermocouple temperature sensors are provided and spaced apart along the axial direction of the heat-conducting component 1. Specifically, two thermocouple temperature sensors are spaced apart on the heat-conducting component 1, and the two thermocouple temperature sensors are arranged sequentially and spaced apart along the axial direction of the heat-conducting component 1. Please refer to... Figure 1 One thermocouple temperature sensor is located at the intersection of the first heat conductor 11 and the second heat conductor 12, and the other thermocouple temperature sensor is located near the end of the second heat conductor 12 facing away from the first heat conductor 11. Both thermocouple temperature sensors are connected to the temperature control component 4.

[0087] To improve the accuracy of the data detected by the thermocouple temperature sensor, the thermocouple temperature sensor can be attached to the outer wall of the heat-conducting component 1, or a hole (non-through blind hole) can be drilled in the outer wall so that the installation position of the thermocouple temperature sensor can be as close as possible to the side of the heat-conducting component 1 that is in contact with the atomizing matrix 20.

[0088] In other similar embodiments, the temperature control component 4 can adjust the irradiation energy density of the laser beam irradiated onto the surface of the first heat conductor 11 by adjusting the physical characteristics of the laser beam irradiated onto the first heat conductor 11 without changing the power of the laser irradiation part 21.

[0089] Please see Figure 3 and Figure 4 The heating component 2 also includes an optical adjustment section 22, which is located between the laser irradiation section 21 and the first heat conductor 11. The temperature control component 4 includes a controller 41 electrically connected to the optical adjustment section 22. The controller 41 is used to adjust the optical adjustment section 22 according to the detection result of the temperature measuring component 3, so as to adjust the characteristics of the laser beam emitted by the laser irradiation section 21 through the optical adjustment section 22.

[0090] Specifically, in response to the temperature signal, the temperature control component 4 can generate a control signal and output the control signal to the optical adjustment unit 22 to change the characteristics of the laser beam that the laser irradiation unit 21 acts on the surface of the first heat conductor 11. By adjusting the irradiation energy density of the laser irradiation unit 21 acting on the surface of the first heat conductor 11, the heating power applied by the laser irradiation unit 21 to the heat conductor 1 is adjusted.

[0091] The optical adjustment unit 22 can adjust the heating power of the heating component 2 by changing the area of ​​the light-illuminated area that the laser irradiation unit 21 acts on the surface of the first heat conductor 11.

[0092] In some embodiments, the optical adjustment unit 22 includes a lens, which can change the propagation characteristics of the laser beam by adjusting the distance between the lens and the first heat conductor 11, thereby changing the convergence or divergence of the laser beam that passes through the lens and irradiates the first heat conductor 11, thereby adjusting the size of the laser spot irradiating the surface of the first heat conductor 11 and the irradiation energy density.

[0093] Specifically, the lens mentioned above is a convex lens 221.

[0094] In other similar embodiments, the optical adjustment unit 22 includes a lens with adjustable focal length. By changing the focal length of the lens, the size of the laser spot that passes through the lens and irradiates the surface of the first heat conductor 11 changes, thereby increasing or decreasing the irradiation energy density.

[0095] The structure of the optical adjustment unit 22 provided in the embodiments of this application will be further explained below, taking a lens with a fixed focal length as an example.

[0096] Please see Figure 3 and Figure 4 The optical adjustment unit 22 includes a convex lens 221 and a sliding guide 222. The convex lens 221 is located between the laser irradiation unit 21 and the first heat conductor 11 and can slide relative to the sliding guide 222 to move closer to or further away from the first heat conductor 11, thereby adjusting the characteristics of the laser beam emitted by the laser irradiation unit 21 toward the first heat conductor 11.

[0097] Assuming the power of the laser irradiation unit 21 remains constant, the intensity of the laser emitted by the laser irradiation unit 21 remains constant. Correspondingly, its heating temperature (or heating intensity) changes according to the irradiation range of the laser beam. When the irradiation range of the laser beam increases, the maximum temperature that the irradiated area can be heated decreases. This is because a smaller irradiation area results in more concentrated laser energy, while a larger irradiation area results in more dispersed laser energy, thus reducing the heating intensity per unit area. Therefore, the optical adjustment unit 22 can control the heating temperature of the heat-conducting component 1 by adjusting the irradiation area of ​​the laser beam. For example, the optical adjustment unit 22 can increase or decrease the irradiation area based on the temperature required to heat the atomized matrix 20.

[0098] Of course, to facilitate the adjustment of the position of the convex lens 221, the optical adjustment unit 22 in this embodiment also includes a displacement driving component electrically connected to the controller 41. The displacement driving component is connected to the convex lens 221 and is used for control by the controller 41 to drive the convex lens 221 to slide relative to the sliding guide 222.

[0099] For example, the sliding guide 222 can be configured as a platform-like structure with a slide rail, or it can simply be a guide rail or similar structure. The convex lens 221 has a slider structure that slides and engages with the sliding guide 222. The displacement drive assembly can drive the convex lens 221 to slide relative to the sliding guide 222 by driving the slider to slide along the sliding guide 222. The displacement drive assembly can be a linear drive motor (e.g., a stepper motor), a lead screw, or other device with linear drive function. Its structure has been disclosed in related technologies and will not be described in detail here.

[0100] The controller 41 mentioned above can be a PCB (Printed Circuit Board), which includes a processor. The processor can be a central processing unit (CPU), or other general-purpose processors, microcontrollers, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), programmable logic controllers (PLCs), discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor.

[0101] In addition to the processor described above, the controller 41 may also include a memory and a computer program stored in the memory that can run on the processor. For example, the program may contain programs for controlling the start and stop of the laser irradiation unit 21 and adjusting its power, and / or for controlling the position of the convex lens 221 in the optical adjustment unit 22. The processor can execute the computer program to adjust the irradiation energy density of the heating member 2 acting on the surface of the first heat conductor 11 by controlling the laser irradiation unit 21 and / or the optical adjustment unit 22.

[0102] In other embodiments of this application, heat-conducting components 1 with different structures are also provided.

[0103] Please see Figure 5 , Figure 6 and Figure 7 The second heat conductor 12 in the heat-conducting component 1 includes a central heat conductor 122. The central heat conductor 122 is connected to the middle of one side surface of the first heat conductor 11. When the heat-conducting component 1 is connected to the atomizing matrix 20, the central heat conductor 122 is inserted into the atomizing matrix 20 to heat the atomizing matrix 20 from the inside.

[0104] Similarly, the first heat conductor 11 and the central heat conductor 122 are integral structures, which are molded as one piece and made of the same material.

[0105] Specifically, when the atomizing matrix 20 is installed on the heat-conducting component 1, the first heat conductor 11 can contact one end of the atomizing matrix 20 in the circumferential direction, and the central heat conductor 122 can be inserted into the atomizing matrix 20. To facilitate the connection between the heat-conducting component 1 and the atomizing matrix 20, the end of the central heat conductor 122 facing away from the first heat conductor 11 can be designed with a sharp structure. During the process of the atomizing matrix 20 being inserted into the central heat conductor 122 from top to bottom and contacting the first heat conductor 11, the bottom surface of the atomizing matrix 20 is inserted into the central heat conductor 122, at which time the atomizing matrix 20 can wrap around the central heat conductor 122.

[0106] When the heat-conducting component 1 is heated, the first heat-conducting body 11 can contact and heat one end of the atomizing matrix 20 in the axial direction, and the central heat-conducting body 122 can directly contact the interior of the atomizing matrix 20 and heat the interior of the atomizing matrix 20, so that the atomizing matrix 20 can obtain a more sufficient heating effect.

[0107] For the structure of the heat-conducting component 1 along its axial direction and viewed from a top angle, please refer to [reference needed]. Figure 6 The first heat conductor 11 is a circular sheet structure, and the central heat conductor 122 is connected to the center of the first heat conductor 11 and extends along the axial direction of the heat conductor 1.

[0108] Specifically, when the central heat conductor 122 is cylindrical, rod-shaped, or needle-like in structure, please refer to [reference needed]. Figure 6 In (b), the axial projection of the central heat conductor 122 is circular; when the axial projection of the central heat conductor 122 is a cross-shaped structure, please refer to [reference needed]. Figure 6 (a) In the diagram; when the central heat conductor 122 has a straight-line structure in the axial direction, please refer to [reference needed]. Figure 6 (c) Of course, the axial projection of the central heat conductor 122 can also be a T-shaped structure or other structures. When the central heat conductor 122 is a cross-shaped structure or a straight structure, part of the structure of the central heat conductor 122 can extend from the middle towards the outer periphery of the atomizing matrix 20. This not only helps to increase the contact area between the central heat conductor 122 and the atomizing matrix 20 and improve the heating effect on the atomizing matrix 20, but also helps to increase the heating rate of the outer side and the area near the outer side of the atomizing matrix 20, further improving the problem of different heating rates at different positions of the atomizing matrix 20.

[0109] Please see Figure 5 and Figure 7 In order to facilitate better fixation of the atomizing matrix 20 and protect the outer wall of the atomizing matrix 20, in some embodiments, the heating component 10 is further provided with a heat insulation sleeve 5, which can contact the sealing ring 6 mentioned above.

[0110] Specifically, the thermal insulation sleeve 5 is used to accommodate at least a portion of the atomizing matrix 20. When the thermal insulation sleeve 5 is in contact with the atomizing matrix 20, the thermal insulation sleeve 5 can be fitted over the atomizing matrix 20 and maintain a close fit or interference fit with the outer wall of the atomizing matrix 20.

[0111] It should be noted that the thermal conductivity of the insulation jacket 5 is less than that of the thermal conductivity of the heat-conducting component 1.

[0112] Specifically, the thermal insulation sleeve 5 is made of a material with poor thermal conductivity, such as glass or ceramic. Meanwhile, to minimize the impact of the thermal insulation sleeve 5 on the heating effect of the heating component 10, the thermal insulation sleeve 5 and the heat-conducting component 1 can be spaced apart.

[0113] Please see Figure 5 and Figure 7 There is a gap between the end of the heat insulation sleeve 5 near the first heat conductor 11 and the outer periphery of the first heat conductor 11.

[0114] To avoid the thermal insulation sleeve 5 affecting the detection accuracy of the thermocouple temperature sensor, in this embodiment, there are at least two thermocouple temperature sensors. One is connected to the outer periphery of the first heat conductor 11, and the other is connected to the thermal insulation sleeve 5. The thermal insulation sleeve 5 has perforations or non-penetrating blind holes for accommodating the thermocouple temperature sensor. Through these perforations or blind holes, the thermocouple temperature sensor can be brought as close as possible to the atomizing matrix 20, thereby improving its temperature measurement accuracy and reducing the impact of the thermal insulation sleeve 5 on the detection accuracy of the thermocouple temperature sensor.

[0115] Figure 5 and Figure 7 The difference is that, Figure 5 The laser irradiation section 21 in the middle directly irradiates the heat-conducting component 1; Figure 7 The laser irradiation unit 21 in the optical adjustment unit 22 irradiates the heat-conducting member 1 through the convex lens 221 in the optical adjustment unit 22. For details, please refer to the previous text, and will not be repeated here.

[0116] In other similar embodiments, a heating assembly 10 with another thermally conductive component 1 structure is also provided; please refer to [link to relevant documentation]. Figure 8 , Figure 9 and Figure 10 Compared to the aforementioned embodiments, this heat-conducting component 1 includes both a peripheral heat conductor 121 and a central heat conductor 122. For details regarding the corrosion structure of the heat-conducting component 1, please refer to [link to previous description]. Figure 9 In the figure, the peripheral heat conductor 121 has a ring structure, and the central heat conductor 122 includes three different shapes, as shown below. Figure 9 As shown in (a), (b) and (c) in the figure.

[0117] In this embodiment, the heat-conducting component 1 is a tubular structure with one open end. The first heat-conducting body 11 is located at one end of the tubular structure near the heating component 2 along the axial direction. The central heat-conducting body 122 is in contact with the side surface of the first heat-conducting body 11 facing away from the heating component 2 and extends axially away from the heating component 2. The peripheral heat-conducting body 121 is connected to the circumferential outer edge of the first heat-conducting body 11 and extends axially in the same direction as the central heat-conducting body 122. At this time, a receiving chamber for accommodating the atomizing matrix 20 is formed between the first heat-conducting body 11 and the peripheral heat-conducting body 121. The central heat-conducting body 122 can be inserted into the atomizing matrix 20 located in the receiving chamber and fixed therein.

[0118] Generally speaking, along the axial direction of the heat-conducting member 1, the length of the peripheral heat-conducting body 121 is greater than or equal to the length of the central heat-conducting body 122.

[0119] It is understood that the heating component 10 provided in this application embodiment improves the structure of the heat-conducting component 1, enabling it to simultaneously heat different positions of the atomizing matrix 20 through the first heat conductor 11 and the second heat conductor 12, thereby improving the heating uniformity and heating efficiency of the heating component 10. This not only improves the taste of the aerosol generated by heating the atomizing matrix 20, but also provides users with a better user experience. At the same time, the heating component 10 can also adjust the heating efficiency of the heating component 2 through the connected temperature measuring component 3 and temperature control component 4, which helps to achieve precise temperature control of the heating component 10.

[0120] In a second aspect, embodiments of this application also provide a heated non-combustible atomizing device, including the heating component 10 described in any of the above claims, and a control switch, which is electrically connected to the heating component 2 to control the start and stop of the heating component 2.

[0121] In the heated non-combustible atomizing device provided in this application embodiment, the heating component 10 can be started and stopped by a control switch to ensure that the heating component 2 can only be started and heat the heat-conducting component 1 when the control switch is on, thereby improving the safety of the heated non-combustible atomizing device during use.

[0122] To further improve its safety, in some embodiments, the heated non-combustible atomizing device also includes a positioning sensor. The positioning sensor is installed on the side of the first heat conductor 11 facing the second heat conductor 12 and is electrically connected to the heating element 2 to detect whether the atomizing substrate 20 to be heated is properly installed. The positioning sensor can be connected in series with a control switch to avoid safety risks caused by accidental activation of the control switch when the atomizing substrate 20 is not inserted. For the structure and connection method of the control switch and positioning sensor, please refer to the technical solutions disclosed in related technologies; this embodiment does not specifically limit them.

[0123] For example, the number of positioning sensors can be set to one and disposed on the surface of the first heat conductor 11 facing away from the heating member 2. When the positioning sensor detects an item, it means that the atomizing matrix 20 is now in place.

[0124] Specifically, the position sensor can be set as a position sensor (e.g., photoelectric position sensor), a pressure sensor (e.g., strain gauge pressure sensor, piezoelectric pressure sensor, etc.).

[0125] For example, the number of the aforementioned positioning sensors can also be two, located on the upper and lower halves of the heat-conducting member 1 along its axial direction, respectively. That is, they are located on the first heat conductor 11 and the second heat conductor 12 of the heat-conducting member 1, respectively.

[0126] Two positioning sensors are defined along the axial direction of the heat-conducting component 1 as the upper positioning sensor and the lower positioning sensor, respectively. Both the upper and lower positioning sensors are electrically connected to the control switch. In use, when both the upper and lower positioning sensors detect the atomizing matrix 20, it means that the atomizing matrix 20 is installed correctly; when only the upper positioning sensor detects the atomizing matrix 20, it means that the atomizing matrix 20 is not installed correctly; when neither positioning sensor detects the atomizing matrix 20, it means that the atomizing matrix 20 is not installed.

[0127] Of course, the heated non-combustible atomizing device also has other structures, such as a shell covering the heating component 10.

[0128] It is understood that the heating non-combustible atomizing device provided in this application embodiment includes the beneficial effects of any one or more of the heating components 10 described above, which will not be repeated here.

[0129] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0130] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
