Description

Technical Field

[0001] The present application relates to the technical field of aerosol generating devices, and particularly to a heating component and an aerosol generating device. Background Art

[0002] In related technologies, an aerosol generating device that heats by means of air convection generally includes a heating element for being powered on, a heat conducting member, and an aerosol generating matrix. Among them, the heating element is exposed to the aerosol environment and is easily corroded, resulting in poor reliability of the aerosol generating device. Summary of the Invention

[0003] The present application provides a heating component and an aerosol generating device.

[0004] The heating component according to an embodiment of the present application includes a hollow tube, a conductive member, and a multi-channel heat conducting member. The hollow tube is formed with a gas passage; the conductive member is disposed outside the hollow tube and is used for heating the hollow tube when powered on; the multi-channel heat conducting member is disposed in the gas passage and is thermally connected to the hollow tube. The multi-channel heat conducting member is formed with a plurality of diversion channels, and the diversion channels communicate the gas passages on both sides of the multi-channel heat conducting member.

[0005] In the heating component according to the embodiment of the present application, the conductive member is disposed outside the hollow tube, and the gas passage is completely isolated from the conductive member and the circuit environment outside the hollow tube, avoiding the influence of air flow on the electrical connection, and improving the heating stability and the reliability of the heating component. In addition, by heating the hollow tube with the conductive member, the hollow tube transfers heat to the multi-channel heat conducting member inside the hollow tube, and the multi-channel heat conducting member heats the gas flowing through the hollow tube. The heat conducting contact area of the plurality of diversion channels is large, the heating speed is fast and relatively uniform, and the heating efficiency of the heating component can be improved.

[0006] In some embodiments, the gas passage is used for accommodating an aerosol generating matrix.

[0007] In this way, hot air can flow through the aerosol forming matrix and diffusely heat the entire aerosol generating matrix, so that the aerosol generating matrix can be fully released.

[0008] In some embodiments, the hollow tube includes a first tube section and a second tube section connected to the first tube section. The first tube section is used for accommodating an aerosol generating matrix, and the second tube section is thermally connected to the multi-channel heat conducting member.

[0009] In this way, the heating component can simultaneously heat the aerosol generating matrix by using heat transfer, thermal radiation of the hollow tube, and convection of hot air, improving the energy efficiency utilization rate.

[0010] In some embodiments, the multi-channel heat conducting member is used for being spaced apart from the aerosol generating matrix.

[0011] In this way, the multi-channel heat conducting member is spaced apart from the aerosol generating substrate, which is conducive to the dispersion of hot air and fully heating the aerosol generating substrate.

[0012] In some embodiments, the conductive member is a coil wound around the outside of the hollow tube for exciting the hollow tube to generate heat when energized.

[0013] In this way, the coil can use electromagnetic induction to heat the hollow tube, improving the heating efficiency and providing a relatively wide heating temperature range.

[0014] In some embodiments, at least a part of the hollow tube is a metal tube, the coil is wound around the metal tube, and the multi-channel heat conducting member is thermally connected to the metal tube.

[0015] In this way, when the coil is energized, the metal tube can be heated by electromagnetic excitation.

[0016] In some embodiments, the multi-channel heat conducting member is fixedly connected to the hollow tube. In some embodiments, the multi-channel heat conducting member is detachably connected to the hollow tube.

[0017] In this way, the fixed connection between the multi-channel heat conducting member and the hollow tube is conducive to maintaining the stability of heat transfer. The detachable connection between the multi-channel heat conducting member and the hollow tube facilitates the replacement of the multi-channel heat conducting member.

[0018] In some embodiments, the conductive member is a thermal resistance member for heating up and transferring heat to the hollow tube when energized.

[0019] In this way, when the conductive member is a thermal resistance member, the structure can be simplified and the cost can be reduced by resistance heating.

[0020] In some embodiments, the multi-channel heat conducting member is formed with a plurality of micropores, and the plurality of micropores together form a diversion channel.

[0021] In this way, a plurality of diversion channels are formed through the plurality of micropores, increasing the contact area of the gas in the diversion channels and improving the heat transfer efficiency.

[0022] In some embodiments, the diversion channel extends along the axial direction of the hollow tube and penetrates through the multi-channel heat conducting member.

[0023] In this way, the gas flowing through the hollow tube can be guided from one end of the axial direction of the hollow tube to the other end through the diversion channel, increasing the heat transfer area without changing the overall flow direction of the gas.

[0024] In some embodiments, the diversion channel is formed on the peripheral surface of the multi-channel heat conducting member, and the diversion channel is curved.

[0025] In this way, by providing a curved diversion channel on the peripheral surface of the multi-channel heat conducting member, the length of the diversion channel can be extended on the limited surface of the multi-channel heat conducting member, improving the utilization rate of the multi-channel heat conducting member.

[0026] In some embodiments, the diversion channel is circuitously curved along the axial direction of the hollow tube.

[0027] In this way, the heat conduction area of the multi-channel heat conducting member for the flowing gas can be increased, and the heat exchange efficiency can be improved.

[0028] The aerosol generating device according to the embodiment of the present application includes the heating component according to any one of the above embodiments.

[0029] In the aerosol generating device according to the embodiment of the present application, the multi-channel heat conducting member in the heating component heats the air, and the aerosol generating matrix is heated by the hot air, so that the heating rate and the heating uniformity can be improved, thereby improving the efficiency and quality of aerosol generation.

[0030] In some embodiments, the aerosol generating device includes a housing having a receiving cavity, an air inlet and an air outlet. The hollow tube is at least partially disposed in the receiving cavity, and both the air inlet and the air outlet are communicated with the hollow tube. A first sealing member is disposed between the air inlet and the hollow tube, and the first sealing member seals the space between the air inlet and the hollow tube; and / or, in some embodiments, a second sealing member is disposed between the air outlet and the hollow tube, and the second sealing member seals the space between the air outlet and the hollow tube.

[0031] In this way, the space between the air outlet, the air inlet and the hollow tube is sealed by the first sealing member and the second sealing member, so that the receiving cavity is isolated from the gas channel, and the aerosol generating matrix, the aerosol and the condensed aerosol are all in the gas channel, thereby preventing the aerosol from entering the receiving cavity and affecting the electrical connection. In addition, the condensation of the aerosol in the receiving cavity can also be reduced, which is beneficial to keeping the inside of the aerosol generating device clean.

[0057] Please refer to Figure 1 , this application provides a heating component 100 and an aerosol generating device 1000. The heating component 100 is used to heat an aerosol generating substrate 50 in the aerosol generating device 1000 to form an aerosol. The aerosol generated in the aerosol generating device 1000 can be used for various purposes such as food consumption, medicine use, and industrial production.

[0058] Please refer to Figures 2 - 4 , the heating component 100 of the embodiment of this application includes a hollow tube 10, a conductive member 20, and a multi-channel heat conducting member 30. Among them, the hollow tube 10 is formed with a gas channel 40; the conductive member 20 is disposed outside the hollow tube 10, and the conductive member 20 is used to heat the hollow tube 10 when energized; the multi-channel heat conducting member 30 is disposed in the gas channel 40 and is thermally connected to the hollow tube 10. The multi-channel heat conducting member 30 is formed with a plurality of diversion channels 32, and the diversion channels 32 communicate with the gas channels 40 on both sides of the multi-channel heat conducting member 30.

[0059] In the heating component 100 of the embodiment of the present application, the conductive member 20 is disposed outside the hollow tube 10, and the gas channel 40 is completely isolated from the conductive member 20 and the circuit environment outside the hollow tube 10, avoiding the influence of air flow on the electrical connection, and improving the heating stability and reliability of the heating component 100. In addition, the hollow tube 10 is heated by the conductive member 20, and the heat of the hollow tube 10 is transferred to the multi-channel heat conducting member 30 inside the hollow tube 10. The multi-channel heat conducting member 30 heats the gas flowing through the hollow tube 10. Multiple diversion channels 323 are formed on the multi-channel heat conducting member 30, with a large heat conducting contact area, fast and relatively uniform heating speed, and can improve the heating efficiency of the heating component 100.

[0060] Specifically, when the conductive member 20 is energized, it heats the hollow tube 10. The hollow tube 10 is heated to a relatively high temperature, and the heat is transferred to the multi-channel heat conducting member 30 in the hollow tube 10. Cold air enters the hollow tube 10 and flows along the gas channel 40 through the multi-channel heat conducting member 30, and is heated by the multi-channel heat conducting member 30 into hot air. Then the hot air can enter the aerosol generation matrix 50, heating the aerosol generation matrix 50 to generate aerosol. The generated aerosol can flow in the gas channel 40. The aerosol can contain volatile compounds, and the user can inhale the aerosol and / or the volatile compounds in the aerosol into the mouth, nose or lungs through the mouth or nose.

[0061] The hollow tube 10 is a through tube with both ends open, and the tube wall of the hollow tube 10 defines the gas channel 40. In the heating component 100 and the aerosol generation device 1000, the flow range of the gas for heating and the generated aerosol is limited by the range of the gas channel 40. The gas can enter the gas channel 40 from one end of the hollow tube 10 and flow out from the other end of the hollow tube 10. The hollow tube 10 can be cylindrical, cuboid, conical, spindle-shaped, etc. The present application does not limit the specific shape and structure of the hollow tube 10. For the convenience of indication, in the following description and drawings, a cylindrical tube body with a uniform wall thickness of the hollow tube 10 in an embodiment is taken as an example for description, and it is stipulated that the end of the hollow tube 10 where air flows in is the first end 11, and the end where air and aerosol flow out is the second end 12.

[0062] The conductive member 20 can be disposed on the outer side of the tube wall of the hollow tube 10, can be attached to the outer wall of the hollow tube 10, or can maintain a certain gap from the outer wall of the hollow tube 10. The conductive member 20 can be a coil 21, a resistance wire, a heating film, etc. The power connection line of the conductive member 20 is also disposed outside the hollow tube 10. The gas channel 40 inside the hollow tube 10 is completely isolated from the conductive member 20 outside the hollow tube 10, which can avoid the influence of air flow on the stability of the electrical components, and can also avoid the influence of the conductive member 20 and the external circuit environment on the flow heat transfer of the air flow or the generation and suction of the aerosol.

[0063] The multi-channel heat conducting member 30 is disposed in the gas channel 40 and is located between the first end 11 and the second end 12 of the hollow tube 10. A plurality of diversion channels 32 are formed on the multi-channel heat conducting member 30, which can guide the gas in the gas channel 40 to flow dispersedly along the plurality of diversion channels 32. Compared with the single end-to-end gas flow path, the gas flowing through the plurality of diversion channels 32 significantly increases the heat exchange area. The multi-channel heat conducting member 30 is thermally connected to the hollow tube 10. When the conductive member 20 is energized and working, the hollow tube 10 is heated up, thereby heating the multi-channel heat conducting member 30. When the user inhales the aerosol, air flows from the first end 11 to the second end 12 and flows through the multi-channel heat conducting member 30. The multi-channel heat conducting member 30 can be disconnected from the circuit environment and does not make electrical contact with any component, thereby further ensuring the isolation of various gases in the gas channel 40 from the circuit, especially the isolation of the aerosol from the circuit.

[0064] In the radial direction of the hollow tube 10, the multi-channel heat conducting member 30 can be located at the center of the hollow tube 10 to fully and evenly heat the flowing gas. To improve the efficiency of air heating, a plurality of multi-channel heat conducting members 30 can be placed within the range covered by the conductive member 20 along the axial direction of the hollow tube 10, and the number range of the multi-channel heat conducting members 30 can be from 2 to 10. Exemplarily, as Figure 11 shown, the number of the multi-channel heat conducting members is 4, and the 4 multi-channel heat conducting members are arranged in sequence along the circumferential direction of the hollow tube. When air flows through the hollow tube 10, it can be heated multiple times.

[0065] Please refer to Figure 4 , in some embodiments, the gas channel 40 is used to accommodate the aerosol generating substrate 50.

[0066] In this way, the hot air can flow through the aerosol forming substrate and diffusely heat the entire aerosol generating substrate 50, so that the aerosol generating substrate 50 can be fully released.

[0067] Specifically, during the process of air flowing from the first end 11 to the second end 12, the multi-channel heat conducting member 30 can quickly heat the cold air, so that the hot air flows into the aerosol generating substrate 50 and quickly diffuses, heating the aerosol generating substrate 50 to generate aerosol. The aerosol generating substrate 50 can be solid or liquid. In the embodiments of the present application, the air can be heated quickly and evenly, so that after the hot air flows into the aerosol generating substrate 50, it can quickly diffuse to the area where the aerosol generating substrate 50 is located and fully heat the entire aerosol generating substrate 50, so that the aerosol generating substrate 50 can fully release the aerosol.

[0068] In addition, by using the conductive member 20 outside the hollow tube 10 and the hollow tube 10 forming the gas channel 40 as heat sources and using air as the heat transfer medium, the integrity of the aerosol generation matrix 50 can be fully maintained during the heating process, so that the aerosol generation matrix 50 is not prone to slagging and is not easily contaminated.

[0069] Please refer to Figure 7 and Figure 8 , in some embodiments, the hollow tube 10 includes a first tube section 101 and a second tube section 102 connected to the first tube section 101. The first tube section 101 is used to accommodate the aerosol generation matrix 50, and the second tube section 102 is thermally connected to the multi-channel heat conducting member 30.

[0070] In this way, the heating assembly 100 can simultaneously heat the aerosol generation matrix 50 by using the heat transfer, heat radiation of the hollow tube 10, and the convection of hot air, improving the energy efficiency utilization rate.

[0071] Specifically, the first tube section 101 and the second tube section 102 can be an integral structure or a split structure. The first tube section 101 can be the part of the hollow tube 10 into which the aerosol generation matrix 50 is inserted, and the second tube section 102 can be the part of the hollow tube 10 between the end face of the aerosol generation matrix 50 close to the first end 11 and the first end 11. The first tube section 101 and the second tube section 102 can be made of the same material and can be integrally formed into a whole. The first tube section 101 and the second tube section 102 can also be a split structure and can be connected by the same material or different materials.

[0072] The first tube section 101 can accommodate the aerosol generation matrix 50 and the aerosol, and the second tube section 102 can heat the multi-channel heat conducting member 30 when the conductive member 20 is energized. In some embodiments, the first tube section 101 can also directly heat the aerosol generation matrix 50. The heat for the first tube section 101 to heat the aerosol generation matrix 50 can be from the heat transfer of the second tube section 102, from the direct heating of the conductive member 20, or from other heat sources outside the hollow tube 10. In the present application, for better illustration and explanation, the first tube section 101 and the second tube section 102 are described as two parts, but this should not be used as a limitation on the integral and split forms.

[0073] Exemplarily, when the user inhales the aerosol, cold air flows into the gas channel 40 from the first end 11 and enters the high-temperature multi-channel heat conducting member 30. The cold air is heated into hot air in the second pipe section 102. Subsequently, in the first pipe section 101, the hot air enters the aerosol generating matrix 50 for heating. After the aerosol generating matrix 50 is heated, it generates aerosol and carries the active substances in the aerosol into the user's respiratory system. During the interval between the user's inhalations, the first pipe section 101 can directly heat the aerosol generating matrix 50, so as to continuously generate aerosol during use.

[0074] Please continue to refer to Figure 7 and Figure 8 , in some embodiments, the multi-channel heat conducting member 30 is used to be arranged at an interval from the aerosol generating matrix 50.

[0075] In this way, the multi-channel heat conducting member 30 and the aerosol generating matrix 50 are arranged at an interval, which is beneficial to the dispersion of hot air and fully heating the aerosol generating matrix 50. In addition, the multi-channel heat conducting member 30 and the aerosol generating matrix 50 are arranged at an interval, which is also beneficial to the uniform heating of the aerosol generating matrix 50.

[0076] Specifically, in the gas channel 40, along the direction from the first end 11 to the second end 12 of the hollow tube 10, the multi-channel heat conducting member 30 and the aerosol generating matrix 50 are arranged at an interval. After the air is heated by the multi-porous heat conducting member, it diffuses into the aerosol generating matrix 50 to heat the aerosol. By arranging the multi-channel heat conducting member 30 and the aerosol generating matrix 50 at an interval, it can also prevent the heat generating components such as the multi-channel heat conducting member 30 from invading or contacting the aerosol generating matrix 50, resulting in local temperature anomalies and affecting the quality of the aerosol generating matrix 50 and the generation of the aerosol.

[0077] The multi-channel heat conducting member 30 can also limit the depth of the aerosol generating matrix 50 inserted into the hollow tube 10.

[0078] It should be noted that in order to reduce the heat loss of the hot air and considering the miniaturization of the heat generating component 100, the distance between the multi-channel heat conducting member 30 and the aerosol generating matrix 50 should not be too large.

[0079] In some embodiments, the hollow tube 10 can be kept vertical. The first pipe section 101 is the upper part pipe section of the hollow tube 10, the second pipe section 102 is the lower part pipe section of the hollow tube 10, the second end 12 is the top end of the hollow tube 10, and the first end 11 is the bottom end of the hollow tube 10. The multi-channel heat conducting member 30 is arranged below the aerosol generating matrix 50 and can be arranged at the bottom of the hollow tube 10. Such an arrangement can utilize the natural rise of the hot air flow to realize air convection heating of the aerosol generating matrix 50, which is beneficial to reducing energy consumption and improving the heating efficiency.

[0080] The multi-channel heat conducting member 30 has good thermal conductivity and a large heat transfer area. It can quickly heat the air and heat the air to a relatively high temperature. On the one hand, it can improve the heating efficiency and quickly generate aerosol. On the other hand, it can also provide a relatively wide temperature range for the generation of aerosol, so as to facilitate debugging the taste, fluidity, particle size, density, etc. of the aerosol by adjusting the heating temperature.

[0081] Please refer to Figure 4 , in some embodiments, the conductive member 20 is a coil 21 wound around the outside of the hollow tube 10 for exciting the hollow tube 10 to generate heat when energized.

[0082] In this way, the coil 21 can use electromagnetic induction to heat the hollow tube 10, improve the heating efficiency, and can provide a relatively wide heating temperature range.

[0083] Specifically, the conductive member 20 is a coil 21 formed by winding wires. The coil 21 can be formed by winding wires of different materials and different cross-sectional areas. The wires can be wound in different turn densities in the clockwise or counterclockwise direction. The material of the coil 21 is generally a metal and its alloy with high conductivity, such as metals and their alloys such as copper, silver, gold, and aluminum. The present application does not limit the formation method of the coil 21. In the heating component 100, a suitable winding method of the coil 21 can be selected according to the dimensions, materials of components such as the hollow tube 10, the multi-channel heat conducting member 30, and the aerosol generating matrix 50, as well as the power and type of power supply.

[0084] It can be understood that when the coil 21 is energized and working, it generates an oscillating electromagnetic field. The wound hollow tube 10 is located in the oscillating electromagnetic field, and eddy currents are generated under the action of electromagnetic induction and heated to a relatively high temperature.

[0085] The coil 21 can be wound around the entire tube section of the hollow tube 10, or only around a part of the tube section of the hollow tube 10. For example, please refer to Figure 7 , the coil 21 is only wound around the outside of the second tube section 102. The multi-channel heat conducting member 30 is arranged in the second tube section 102, and the heat of the hollow tube 10 is transferred to the multi-channel heat conducting member 30. The multi-channel heat conducting member 30 transfers the heat to the air flowing through the multi-channel heat conducting member 30, and generates aerosol by heating the aerosol forming matrix with hot air.

[0086] Another example, please refer to Figure 8 , the coil 21 is wound around the outside of the first tube section 101 and the second tube section 102. When the hollow tube 10 generates heat under electromagnetic excitation, the heat can be transferred to the multi-channel heat conducting member 30 in the second tube section 102 and the aerosol generating matrix 50 in the first tube section 101 at the same time.

[0087] The coil 21 generates eddy current to heat the hollow tube 10 under the action of electromagnetic induction, which is beneficial to the uniform heating of the periphery of the hollow tube 10. Especially for the hollow tube 10 with uniform lateral dimensions, the heating uniformity is better.

[0088] The coil 21 can be powered by the battery 700, and the current and output power can also be controlled by the control component 600, so as to control the heating temperature. Utilizing the electromagnetic induction between the coil 21 and the hollow tube 10 for heating can quickly heat the multi-channel heat conducting member 30 to a relatively high temperature, improving the heating efficiency and broadening the heating temperature range, while facilitating temperature adjustment.

[0089] Please refer to Figures 2 - 4 , in some embodiments, at least part of the hollow tube 10 is a metal tube 13, the coil 21 is wound around the metal tube 13, and the multi-channel heat conducting member 30 is thermally connected to the metal tube 13.

[0090] In this way, when the coil 21 is energized, the metal tube 13 can be heated by electromagnetic excitation.

[0091] Specifically, at least the tube section located around the multi-channel heat conducting member 30 in the hollow tube 10 is the metal tube 13. In some embodiments, the first tube section 101 and the second tube section 102 of the hollow tube 10 can both be the metal tube 13. The metal tube 13 can be made of a metal material with good magnetic conductivity. For example, the metal tube 13 can be made of iron, stainless steel, carbon steel, etc., so as to enhance the heating effect of the hollow tube 10 under the action of magnetic field eddy current.

[0092] The coil 21 can be directly wound around the metal tube 13 and fit against the outer wall of the tube. The diameter of the coil 21 can be slightly larger than the outer diameter of the metal tube 13, so that there is a certain distance between the coil 21 and the outer wall of the metal tube 13. Since the metal tube 13 generates heat under electromagnetic excitation, the coil 21 and the metal tube 13 do not need to be in direct contact.

[0093] The metal tube 13 is heated by the eddy current generated when the coil 21 is energized, can quickly increase in temperature, and can be heated to a relatively high temperature, and can also quickly cool down after heating.

[0094] In the embodiment of the present application, the metal tube 13 can include the second tube section 102 described above, or rather, the second tube section 102 can be a part of the metal tube 13.

[0095] Please refer to Figure 3 , in some embodiments, the multi-channel heat conducting member 30 is in contact with the hollow tube 10. By contacting the multi-channel heat conducting member 30 with the hollow tube 10, heat transfer can be achieved between the multi-channel heat conducting member 30 and the hollow tube 10. By contacting the multi-channel heat conducting member 30 with the metal tube 13, thermal connection between the multi-channel heat conducting member 30 and the metal tube 13 is achieved.

[0096] Specifically, the outer periphery of the multi-channel heat conducting member 30 abuts against the inner wall of the hollow tube 10. The diameter of the multi-channel heat conducting member 30 can be in interference fit or transition fit with the inner diameter of the hollow tube 10. The positions where the multi-channel heat conducting member 30 abuts against the hollow tube 10 can form spaced contact surfaces or relatively continuous contact surfaces. When there is a temperature difference between the multi-channel heat conducting member 30 and the hollow tube 10, heat transfer from high temperature to low temperature can be achieved through the contact surfaces.

[0097] In a specific embodiment, the multi-channel heat conducting member 30 is in a cylindrical shape and made of a metal material. The outer diameter of the multi-channel heat conducting member 30 is slightly larger than the inner diameter of the metal tube 13. The multi-channel heat conducting member 30 is pressed into the metal tube 13 through a jig, and the multi-channel heat conducting member 30 is in interference fit with the metal tube 13. Then, the multi-channel heat conducting member 30 and the metal tube 13 are welded together by laser welding. In this way, it can be ensured that the heat generated by the metal tube 13 can be effectively transferred to the multi-channel heat conducting member 30, and it can also be ensured that the multi-channel heat conducting member 30 is firmly fixed on the metal tube 13.

[0098] Please refer to Figure 9 , in some embodiments, the multi-channel heat conducting member 30 is a porous metal heat conducting body 33.

[0099] In this way, the multi-channel heat conducting member 30 is a metal structure, which has better resistance to thermal shock and is not easily brittle compared with a ceramic structure, which is beneficial to improving the reliability of the heating component 100.

[0100] Specifically, the multi-channel heat conducting member 30 can be made of a variety of different high thermal conductivity metal materials, such as high thermal conductivity aluminum alloy, high thermal conductivity magnesium alloy, high thermal conductivity copper alloy, etc. The multi-channel heat conducting member 30 made of the above materials mainly absorbs heat through the heat transfer and thermal radiation of the hollow tube 10 and is not easily heated under the electromagnetic induction of the coil 21. In some embodiments, the multi-channel heat conducting member 30 can also be made of a ferromagnetic metal material and can be heated by electromagnetic excitation while receiving the heat transfer of the hollow tube 10.

[0101] The porous metal heat conducting body 33 can include a skeleton composed of solid substances, and the skeleton forms a large number of micropores 31. The micropores 31 in the porous metal heat conducting body 33 can form complex flow guiding channels 32. When the air flow flows through the surface of the micropores 31, heat exchange occurs with the porous heat conducting member. The surfaces of all the micropores 31 in the porous metal heat conducting body 33 can be heat exchange surfaces, thus significantly increasing the heat conducting area and improving the heating speed of the heating component 100 for cold air. The micropores 31 can be densely distributed to achieve a large heat transfer area within a limited volume, and the dense distribution of a large number of tiny micropores 31 is also beneficial to heat preservation.

[0102] In the porous metal heat conductor 33, there are various ways to implement the size and distribution of the micropores 31. Among them, the porous metal heat conductor 33 with consistent micropore 31 size and uniform distribution is relatively easy to manufacture. The porous metal heat conductor 33 can be formed by various process methods. The process methods for forming the porous metal heat conductor 33 include but are not limited to wire weaving, laser drilling, extrusion molding, metal mesh stacking, sheet metal stacking, etc.

[0103] For example, Figure 9 The porous metal heat conductor 33 shown in a is formed by the wire weaving process. Figure 9 The porous metal heat conductor 33 shown in b is formed by the laser drilling process. Figure 9 The porous metal heat conductor 33 shown in c is formed by the metal mesh stacking process. Figure 9 The porous metal heat conductor 33 shown in d is formed by the sheet metal stacking process.

[0104] The porous metal heat conductor 33 has a certain thermal inertia. When the user stops sucking, the porous metal heat conductor 33 can preheat or keep warm the gas channel 40, especially the peripheral area of the porous metal heat conductor 33, which can reduce the probability of aerosol condensation in the gas channel 40, is conducive to keeping the gas channel 40 unobstructed, and is convenient for cleaning.

[0105] The hollow tube 10 and the multi-channel heat conducting member 30 need to experience heating and cooling many times during use, undergo long-term hot and cold alternation, and have a large temperature difference. The metal tube 13 and the porous metal heat conducting member 33 have good resistance to thermal shock and are not easily brittle during repeated hot and cold alternation many times, improving the reliability of the heating component 100.

[0106] In some embodiments, the multi-channel heat conducting member 30 is fixedly connected to the hollow tube 10. In this way, the fixed connection between the multi-channel heat conducting member 30 and the hollow tube 10 is beneficial to maintaining the stability of heat transfer. In some embodiments, the multi-channel heat conducting member 30 is detachably connected to the hollow tube 10. The detachable connection between the multi-channel heat conducting member 30 and the hollow tube 10 facilitates the replacement of the multi-channel heat conducting member 30.

[0107] In some embodiments, the multi-channel heat conducting member 30 can be fixed at a predetermined position on the hollow tube 10. The connection position of the multi-channel heat conducting member 30 can be opposite to the position of the outer conductive member 20 of the hollow tube 10 with a space from the wall of the hollow tube 10. The multi-channel heat conducting member 30 can be fixed on the inner wall of the hollow tube 10 by welding, bonding, clamping, etc., or can also be fixedly connected by arranging a mounting member (not shown in the figure) in the hollow tube 10 to cooperate with the micropores 31 of the multi-channel heat conducting member 30.

[0108] In some embodiments, the multi-channel heat conducting member 30 can be set at a fixed position inside the hollow tube 10 when it is working while generating heat. When it is necessary to replace or clean the multi-channel heat conducting member 30, the multi-channel heat conducting member 30 can be removed from the hollow tube 10.

[0109] The multi-channel heat conducting member 30 can adopt different materials, sizes of the micropores 31, distributions of the micropores 31, sizes and forming processes according to different types of heat sources in the heating assembly 100, different types of the aerosol-forming substrate 50, and different sizes of the hollow tube 10 and the aerosol-forming substrate 50, etc. In cases such as when the heating power is adjusted, the multi-channel heat conducting member 30 becomes dirty or is damaged, the original multi-channel heat conducting member 30 in the hollow tube 10 can be disassembled and another suitable multi-channel heat conducting member 30 can be installed.

[0110] Please refer to Figure 10 , in some embodiments, the conductive member 20 is a thermal resistance member 22, which is used to heat up when powered on and transfer heat to the hollow tube 10.

[0111] In this way, since the conductive member 20 is the thermal resistance member 22, the structure can be simplified and the cost can be reduced by resistance heating.

[0112] Specifically, the thermal resistance member 22 can be in various forms such as resistance wire, electric heating plate, electric heating film, electric heating rod, electric heating mesh, etc. The thermal resistance member 22 can be made of a metal material with a relatively high resistivity, such as nickel-chromium alloy or tungsten, etc. The thermal resistance member 22 is in direct contact with the hollow tube 10, and the thermal resistance member 22 can be attached to the outer wall surface of the hollow tube 10. The thermal resistance members 22 can be evenly distributed along the circumferential direction of the hollow tube 10, can be arranged outside the second pipe section 102 and the first pipe section 101, or can be only arranged on the second pipe section 102, that is, around the multi-channel heat conducting member 30.

[0113] In some embodiments, when the coil 21 is powered on, the hollow tube 10 is heated up by electromagnetic excitation, so that the multi-channel heat conducting member 30 absorbs the heat transferred from the hollow tube 10 to the multi-channel heat conducting member 30 and heats up.

[0114] In some embodiments, the multi-channel heat conducting member 30 can be directly heated by electromagnetic excitation, or can be heated under the working of other heat sources. In this embodiment, the multi-channel heat conducting member 30 can be in contact with the hollow tube 10, and at the same time utilize the heat transfer of the hollow tube 10 and the heat of other heat sources. There can also be a gap between the multi-channel heat conducting member 30 and the hollow tube 10, and the heat is absorbed through ways such as thermal radiation and electromagnetic heating.

[0115] Please refer to Figure 9 , Figure 11 and Figure 12 , Figure 11 which includes Figure 12Schematic diagram of the structure of the heating component 100 of the multi-channel heat conducting member 30 shown. In some embodiments, the multi-channel heat conducting member 30 is formed with a plurality of micropores 31, and the plurality of micropores 31 together form a diversion channel 32.

[0116] In this way, a plurality of diversion channels 32 are formed through the plurality of micropores 31, increasing the contact area of the gas in the diversion channel 32 and improving the heat transfer efficiency.

[0117] Specifically, the micropores 31 may be densely distributed within the volume space of the multi-channel heat conducting member 30, as Figure 9 shown. The micropores 31 may also be formed on one end face of the multi-channel heat conducting member 30, as Figure 12 shown. The multi-channel heat conducting member 30 may be made of a metal material, and a plurality of micropores 31 are formed through an etching process. The multi-channel heat conducting member 30 may be cylindrical, and the plurality of micropores 31 are distributed on one end face in the axial direction of the multi-channel heat conducting member 30, and the micropores 31 all penetrate the corresponding end face. The plurality of micropores 31 may be of the same size and evenly distributed on one side surface of the multi-channel heat conducting member 30.

[0118] The thickness d of the end face of the multi-channel heat conducting member 30 where the micropores 31 are formed ranges from 0.05 mm to 1 mm. Exemplarily, the thickness of the end face of the multi-channel heat conducting member 30 may be 0.05 mm, 0.12 mm, 0.24 mm, 0.35 mm, 0.42 mm, 0.54 mm, 0.68 mm, 0.77 mm, 0.95 mm, 1 mm. Correspondingly, the diameter range of the micropores 31 may be less than or equal to 0.6 mm.

[0119] Please refer to Figure 3 、 Figure 11 and Figure 13 . In some embodiments, the diversion channel 32 extends along the axial direction of the hollow tube 10 and penetrates the multi-channel heat conducting member 30.

[0120] In this way, through the diversion channel 32, the gas flowing through the hollow tube 10 can be guided to flow from one end in the axial direction of the hollow tube 10 to the other end, increasing the heat transfer area without changing the overall flow direction of the gas.

[0121] Specifically, the micropores 31 may penetrate one side surface of the multi-channel heat conducting member 30 along the axial direction of the hollow tube 10, thereby forming a diversion channel 32 that extends along the axial direction of the hollow tube 10 and penetrates the multi-channel heat conducting member 30. Air flows in and out along the axial direction of the hollow tube 10. The air is heated through the plurality of diversion channels 32, still flows out along the axial direction of the hollow tube 10 towards the second end 12, and finally enters the aerosol generation matrix 50.

[0122] The diversion channel 32 can also be formed by a groove on the surface of the multi-channel heat conducting member 30. The groove can penetrate the multi-channel heat conducting member 30 along the axial direction of the hollow tube 10 on one side surface of the multi-channel heat conducting member 30.

[0123] Please refer to Figure 13 and Figure 14 , Figure 13 which is Figure 14 a schematic structural view of the heating component 100 including the multi-channel heat conducting member 30 as shown. In some embodiments, the diversion channel 32 is formed on the circumferential surface of the multi-channel heat conducting member 30, and the diversion channel 32 is curved.

[0124] In this way, by providing the curved diversion channel 32 on the circumferential surface of the multi-channel heat conducting member 30, the length of the diversion channel 32 can be extended on the limited surface of the multi-channel heat conducting member 30, improving the utilization rate of the multi-channel heat conducting member 30.

[0125] Specifically, the multi-channel heat conducting member 30 can be coaxial with the hollow tube 10, and the outer circumferential surface of the multi-channel heat conducting member 30 faces the inner wall of the hollow tube 10. Grooves can be formed on the outer circumferential surface of the multi-channel heat conducting member 30, and the grooves and the inner wall of the hollow tube 10 define the formation of the diversion channel 32. The grooves can extend in a curved shape to extend the length of the diversion channel 32. The number of grooves is multiple, and the multiple grooves can be distributed along the circumferential direction of the multi-channel heat conducting member 30.

[0126] In this embodiment, the height h of the multi-channel heat conducting member 30 ranges from 5 mm to 40 mm. The multi-channel heat conducting member 30 and the hollow tube 10 can be in interference fit and fixed by welding.

[0127] Please continue to refer to Figure 13 and Figure 14 , in some embodiments, the diversion channel 32 is tortuously curved along the axial direction of the hollow tube 10.

[0128] In this way, the heat conducting area of the multi-channel heat conducting member 30 for the flowing gas can be increased, improving the heat exchange efficiency.

[0129] Specifically, the multi-channel heat conducting member 30 can be columnar. Curved grooves can be formed on the outer circumferential surface of the multi-channel heat conducting member 30, and the grooves can first extend upward along the axial direction of the hollow tube 10, bend near the edge of the multi-channel heat conducting member 30 in this direction, then extend downward along the axial direction of the hollow tube 10, also extend near the edge of the multi-channel heat conducting member 30 and bend again, and finally penetrate one end face of the multi-channel heat conducting member 30 along the upward direction of the axial direction of the hollow tube 10. The number of times the grooves bend can be an even number of times such as 2 times, 4 times, 6 times, etc. Such a setting can form a diversion channel 32 that is tortuously curved along the axial direction of the hollow tube 10 between the grooves and the inner wall of the hollow tube 10.

[0130] Please refer to Figure 4 The aerosol generating device 1000 according to the embodiment of the present application includes the heating component 100 of any one of the above embodiments.

[0131] In the aerosol generating device 1000 according to the embodiment of the present application, the multi-channel heat conducting member 30 in the heating component 100 heats the air, and the aerosol generating matrix 50 is heated by the hot air, which can improve the heating rate and the uniformity of heating, thereby improving the efficiency and quality of aerosol generation.

[0132] Specifically, the aerosol generating device 1000 is a device that generates aerosol by using the aerosol generating matrix 50. The aerosol generating device 1000 can input aerosol into the respiratory system of the user through the mouth or nose of the user. The aerosol generating matrix 50 is an object that can generate aerosol, and the process of generating aerosol can be a phase change process of the aerosol generating matrix 50. In the aerosol generating device 1000, the heating component 100 can generate heat to heat the aerosol generating matrix 50 to generate aerosol.

[0133] Please refer to Figure 1 and Figure 4 In some embodiments, the aerosol generating device 1000 includes a housing 300. The housing 300 has a receiving cavity 400. The hollow tube 10 is at least partially disposed in the receiving cavity 400, and the receiving cavity 400 is isolated from the gas passage 40.

[0134] Please refer to Figures 4 - 6 The housing 300 has an air inlet 301 and an air outlet 302. Both the air inlet 301 and the air outlet 302 are communicated with the hollow tube 10. In some embodiments, a first sealing member 501 is disposed between the air inlet 301 and the hollow tube 10, and the first sealing member 501 seals the space between the air inlet 301 and the hollow tube 10. In some embodiments, a second sealing member 502 is disposed between the air outlet 302 and the hollow tube 10, and the second sealing member 502 seals the space between the air outlet 302 and the hollow tube 10.

[0135] In this way, the space between the air outlet 302, the air inlet 301 and the hollow tube 10 is sealed by the first sealing member 501 and the second sealing member 502, so that the receiving cavity 400 is isolated from the gas passage 40, thereby avoiding the corrosion of the electrical components in the aerosol generating device by the aerosol. In addition, the condensation of the aerosol in the receiving cavity 400 can also be reduced, which is beneficial to keeping the inside of the aerosol generating device 1000 clean.

[0136] It can be understood that Figure 4 only the components related to this embodiment are described. Those of ordinary skill in the technical field to which the present application belongs can see that in addition to Figure 4In addition to the components described in [reference], the aerosol generating device 1000 may further include other general components. For example, although not indicated, the aerosol generating device 1000 further includes a power source (not indicated) for powering the conductive member 20, a control component (not indicated) for controlling the power source and the conductive member 20, and an electrical connection line, etc.

[0137] Specifically, the housing 300 can form the outer surface of the aerosol generating device 1000 and can also play a role in supporting and protecting. The housing 300 can form a receiving cavity 400 for receiving the heating component 100 and other general components. The gas channel 40 can be composed of one or more components, and the hollow tube 10 is one of the components forming the gas channel 40. By hermetically connecting the hollow tube 10 to the housing 300, the receiving cavity 400 and the gas channel 40 can be isolated from each other. The airflow includes air and the generated aerosol, and the airflow flows in the gas channel 40. Since the gas channel 40 is isolated from the receiving cavity 400, the aerosol generation matrix 50, the aerosol, and the condensed aerosol are all in the gas channel 40, and the aerosol is not easily introduced into the receiving cavity 400, thereby avoiding the influence of the aerosol or other gases on the electrical connection of the aerosol generating device 1000.

[0138] Specifically, the first seal 501 and the second seal 502 can be hollow tube bodies that can accommodate the airflow passing through. In this embodiment, the first seal 501, the hollow tube 10, and the second seal 502 all form part of the gas channel 40. The airflow can flow into the first seal 501 from the air inlet 301, then sequentially enter the hollow tube 10 and the second seal 502, and finally flow out from the air outlet 302.

[0139] The first seal 501 can be hermetically connected to the first end 11 of the hollow tube 10, and the second seal 502 can be hermetically connected to the second end 12 of the hollow tube 10. Further, by hermetically connecting the first seal 501 to the housing 300 to seal the space between the air inlet 301 and the hollow tube 10, and by hermetically connecting the second seal 502 to the housing 300 to seal the space between the air outlet 302 and the hollow tube 10, the gas channel 40 and the receiving cavity 400 can be isolated from each other.

[0140] The aerosol can exist in the form of an aerosol generation matrix 50, an aerosol (gaseous state), and a condensed aerosol, etc. The aerosol generation matrix 50 can be inserted into the hollow tube 10 from the air outlet 302. During the entire cycle of aerosol generation, the aerosol exists only in the airflow channel in various forms. In this way, it is beneficial to improve the purity and quality of the aerosol, avoid the condensation of the aerosol in the receiving cavity 400, make the aerosol generating device 1000 easy to clean, and at the same time can prevent the aerosol from entering the receiving cavity 400 to corrode the circuit and electrical components.

[0141] Please refer toFigure 15 In some embodiments, the first seal 501 includes a first bracket 510 and a first sealing ring 511 mounted on the first bracket 510. The second seal 502 includes a second bracket 520 and a second sealing ring 522 mounted on the second bracket 520. The first bracket 510, the first sealing ring 511, the metal tube 13, the second sealing ring 522, and the second bracket 520 may be sequentially arranged along the axial direction of the hollow tube 10 from the air inlet 301 to the air outlet 302 to form a gas passage 40.

[0142] The first bracket 510 and the second bracket 520 may be hollow tube bodies, coaxial with the hollow tube 10, and are respectively arranged at both ends of the hollow tube 10 in the axial direction to fix the hollow tube 10. The first sealing ring 511 may abut against the first end 11 of the hollow tube 10, and the second sealing ring 522 may abut against the second end 12 of the hollow tube 10 to seal the hollow tube 10 and prevent aerosol from leaking into the electrical environment outside the gas passage 40. The materials of the first bracket 510 and the second bracket 520 may be plastics such as PEEK, and the materials of the first sealing ring 511 and the second sealing ring 522 are generally high-temperature resistant silica gels.

[0143] Please continue to refer to Figure 15 In some embodiments, the aerosol generating device 1000 further includes a control component 600, a temperature measuring element 900, a battery 700, etc. The battery 700 can supply power to devices such as the coil 21, the control component 600, and the temperature measuring component. The control component 600 may include a PCBA board, and the coil 21 can generate an alternating magnetic field under the action of the PCBA board. The temperature measuring element 900 may be arranged between the outer wall of the hollow tube 10 and the coil 21 to detect the temperature of the hollow tube 10. The temperature measuring element 900 may be a PT1000 type platinum resistance or a thermocouple.

[0144] In a specific embodiment, the coil 21 is made of copper, and the coil 21 generates an alternating magnetic field under the circuit control of the PCBA board to inductively heat the hollow tube 10. The material of the hollow tube 10 is SUS430 type stainless steel, the material of the multi-channel heat conducting member 30 is SUS316 type stainless steel, and the thickness d of the multi-channel heat conducting member 30 is 0.15 mm. Four multi-channel heat conducting members 30 are fixed in the tube section of the hollow tube 10 covered by the coil 21. After the hollow tube 10 is inductively heated, it transfers heat to the multi-channel heat conducting member 30, and air flows through the hollow tube 10 and is heated by the multi-channel heat conducting member 30.

[0145] The aerosol generating device 1000 and the heating component 100 according to the embodiments of the present application can heat the hollow tube 10 through electromagnetic excitation, and then heat the multi-channel heat conducting member 30 in the hollow tube 10. During the user's suction, the multi-channel heat conducting member 30 can quickly heat the flowing air, and then heat the aerosol generating substrate 50 through the hot air to form an aerosol. The hot air can uniformly and quickly heat the aerosol generating substrate 50 to a large extent. Therefore, the aerosol generating device 1000 and the heating component 100 according to the embodiments of the present application have a fast heating-up speed and high heating efficiency. At the same time, since the aerosol generating substrate 50 and the aerosol are both disposed in the gas channel 40, and the gas channel 40 is isolated from the accommodating cavity 400 of the aerosol generating device 1000, it is possible to avoid interference between the conductive member 20 and other components of the aerosol generating device 1000 and the aerosol, thereby improving the reliability of the aerosol generating device 1000 and the heating component 100.
