In the related art, the atomizing device uses electrical energy to generate heat from a heating element and then transfers the heat to the aerosol substrate 200, which has a poor energy-saving effect.

[0061] In order to solve the above technical problems, an embodiment of the present application provides an atomizing device, which includes a device body (not shown in the figure) and a heating tube 100, and the heating tube 100 is installed on the device body.

In this way, the atomizing device provided in the embodiment of the present application can convert light energy into heat energy, provide heat for the aerosol matrix 200 to be atomized, and improve the energy saving effect.

[0062] In some embodiments, the heat pipe 100 can rotate around the axis of the first tube 10 relative to the device body, so that the heat pipe 100 can adjust the part exposed to light, which is beneficial for the heat pipe 100 to heat evenly, thereby.

[0063] Please also read Figure 1 and Figure 2 In some embodiments, the atomizing device further includes a power source (not shown in the figure) and a light emitting member (not shown in the figure), the power source is electrically connected to the light emitting member, and the light emitting member is used to emit light 300 toward the heating tube 100 when powered.

[0067] Please also read Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 It can be understood that, when at least part of the second tube 20 is made of a light-transmitting material, the light irradiated to the second tube 20 can continue to irradiate the aerosol substrate 200 through the second tube 20, so that the aerosol substrate 200 can generate heat. When at least part of the second tube 20 has photothermal properties, the light irradiated to the second tube 20 can cause the second tube 20 to generate heat and transfer it to the aerosol substrate 200. In addition, the first part of the light that passes through the first tube 10 can directly cause the second tube 20 to generate heat and then transfer it to the aerosol substrate 200, and the second part of the light that passes through the second tube 20 continues to irradiate the aerosol substrate 200, so that the aerosol substrate 200 can generate heat.

[0068] Optionally, a heat-insulating cavity 101 is formed between the first tube 10 and the second tube 20 , and the heat-insulating cavity 101 can prevent heat loss to a certain extent.

[0069] Exemplarily, the heat-insulating cavity 101 is a negative pressure cavity. Exemplarily, the heat-insulating cavity 101 is a vacuum cavity. Exemplarily, the heat-insulating cavity 101 is a cavity filled with argon gas.

[0070] Optionally, the heat insulation cavity 101 surrounds the second tube 20 along the circumference of the second tube 20. Exemplarily, the first tube 10 and the second tube 20 may be concentrically arranged. Exemplarily, the first tube 10 and the second tube 20 may be eccentrically arranged.

[0071] In summary, the heat pipe 100 provided in the present application can utilize light energy to heat the aerosol matrix 200 to provide at least part of the heat for atomizing the aerosol matrix 200, thereby saving energy and being beneficial to improving energy-saving effects.

[0072] Optionally, the light-transmitting material may be glass, or other light-transmitting and heat-resistant materials.

[0073] Optionally, when the second tube 20 has photothermal properties, the material of the second tube 20 may be black quartz glass. Exemplarily, the emissivity coefficient of black quartz glass is m, and the value range of m may be 0.8≤m≤0.99. Optionally, the value range of m may be 0.8≤m≤0.9. Optionally, the value range of m may be 0.9≤m≤0.99. Optionally, the value of m may be 0.8, 0.5, 0.9, 0.95, 0.99.

[0074] Optionally, when the second tube 20 has photothermal properties, the second tube 20 may be quartz glass with a high emissivity coating provided on the inner and / or outer surfaces. For example, the coating may be a graphite coating, a graphene coating or other photothermal material coating.

[0075] Optionally, when the second tube 20 has photothermal properties, the second tube 20 may be a metal tube. Exemplarily, the material of the second tube 20 includes at least one of stainless steel, copper alloy, aluminum alloy, copper-aluminum alloy, and silver alloy.

[0076] Exemplarily, when the second tube 20 is a metal tube, the inner circumference and / or outer circumference of the second tube 20 may also be provided with a high emissivity coating.

[0077] Exemplarily, when the second tube 20 is a metal tube, the inner circumference and / or outer circumference of the second tube 20 may be blackened. Optionally, the inner circumference and / or outer circumference of the second tube 20 may be oxidized.

[0078] It is understandable that metal is prone to thermal expansion and contraction and deformation when the temperature changes, which may affect the sealing of the connection between the first tube 10 and the second tube 20, and thus may affect the sealing of the insulation cavity 101.

[0079] See also Fig.13 In some embodiments, the heat pipe 100 includes a deformable connector 50 (not shown in the figure), and the first tube 10 and the second tube 20 are connected by the connector 50. In this way, when the second tube 20 is deformed or moved, the connector 50 can be deformed to compensate for the deformation or displacement of the second tube 20. In this way, the connector 50 is conducive to the connection and sealing between the second tube 20 and the first tube 10, and can ensure the sealing of the heat insulation cavity 101 to a certain extent.

[0080] Optionally, the connector 50 may be a corrugated tube or an elastic tube. Optionally, the connector 50 has good high temperature resistance. Optionally, the material of the connector 50 may be Kovar alloy, which can improve the connection reliability between the connector 50 and the first tube 10 and the second tube 20.

[0082] Optionally, opposite ends of the second tube 20 extend out of opposite end surfaces of the first tube 10. The connector 50 includes a first connector end 51 and a second connector end 52. The first connector end 51 is connected to the end surface of the first tube 10, and the second connector end 52 is sealed to the outer peripheral surface of the second tube 20.

[0083] See also Fig.14 Optionally, the connection surface between the first connection end 51 and the first tube 10 is a first connection surface, and the first connection surface surrounds the second tube 20. The first connection surface can extend along the radial direction of the first tube 10 to increase the area of ​​the first connection surface, so that the connection reliability between the first connection end 51 and the first tube 10 can be increased.

[0084] Optionally, the connection surface between the second connection end 52 and the second tube 20 is a second connection surface, and the second connection surface surrounds the second tube 20. The second connection surface can extend along the axial direction of the second tube 20 to increase the area of ​​the second connection surface, so that the connection reliability between the second connection end 52 and the second tube 20 can be increased.

[0085] See also Fig.15 Optionally, the second connection end 52 wraps around the end surface of the second tube 20 and extends toward the inside of the second tube 20. It can be understood that the second connection surface can be connected to the outer circumference, end surface, and inner circumference of the second tube 20, which can increase the connection reliability between the second connection end 52 and the second tube 20.

[0086] See also Fig.16 Optionally, both ends of the first tube 10 are open ends, and the first connecting end 51 of the connecting member 50 can be connected to the outer peripheral surface of the first tube 10. The connecting surface (first connecting surface) between the first connecting end 51 and the first tube 10 extends along the axial direction of the first tube 10. This can facilitate the forming of the first tube 10.

[0087] It is understandable that the first connecting end 51 of the connecting member 50 may also be connected to the inner circumferential surface of the first tube 10 .

[0088] See also Fig.17 Optionally, the first connection end 51 wraps around the end surface of the first tube 10 and extends toward the inside of the first tube 10. It can be understood that the first connection surface can be connected to the outer circumference, end surface, and inner circumference of the first tube 10, which can increase the connection reliability between the first connection end 51 and the first tube 10.

[0089] Please continue reading Figure 6 , Figure 7 and Fig. 9In some embodiments, the wall of the first tube 10 includes a light-transmitting portion and a light-reflecting portion, and the two ends of the light-transmitting portion along the circumference of the first tube 10 are respectively connected to the two ends of the light-reflecting portion along the circumference of the first tube 10, and the surface of the light-reflecting portion facing the axis of the first tube 10 is provided with a first light-reflecting film 30.

[0090] It can be understood that the light 300 can pass through the light-transmitting part and then irradiate the second tube 20, and the part of the light 300 that does not irradiate the second tube 20 can irradiate the first reflective film 30, and the first reflective film 30 can reflect the part of the light 300 to the second tube 20, thereby improving the utilization rate of the light 300 and helping to improve the heating efficiency.

[0091] Optionally, the surface area of ​​the light-transmitting portion is larger than that of the light-reflecting portion, so that more light 300 can pass through the light-transmitting portion to irradiate the second tube 20 and the first light-reflecting film 30, thereby improving the utilization rate of the light 300 and facilitating the heating efficiency.

[0092] In some embodiments, an anti-reflection film (not shown in the figure) may be provided on the inner surface or the outer surface of the light-transmitting portion to increase the intensity of light passing through the light-transmitting portion.

[0093] See also Fig.18 In some embodiments, the heat pipe 100 further includes a heat storage member 40, and the second tube 20 includes a first section 21 and a second section 22 connected in sequence along the axial direction. At least part of the heat storage member 40 is located in the first section 21, the first section 21 is made of a light-transmitting material, and / or the first section 21 has photothermal properties. The second section 22 is used to place the aerosol matrix 200, the second section 22 is made of a light-transmitting material, and / or the second section 22 has photothermal properties.

[0094] It can be understood that when the first section 21 is made of a light-transmitting material, the light irradiated to the first section 21 can continue to irradiate the heat storage component 40 through the first section 21, so that the heat storage component 40 can generate heat and store it. When the first section 21 has photothermal properties, the light irradiated to the first section 21 can cause the first section 21 to generate heat and transfer it to the heat storage component 40 for storage. In addition, part of the light that passes through the first tube 10 can directly cause the first section 21 to generate heat and then transfer it to the heat storage component 40 for storage, and part of the light that passes through the first section 21 continues to irradiate the heat storage component 40, so that the heat storage component 40 can generate heat and store it.

[0095] When the second section 22 is made of a light-transmitting material, the light irradiated to the second section 22 can continue to irradiate the aerosol matrix 200 through the second section 22, so that the aerosol matrix 200 can generate heat. When the second section 22 has photothermal properties, the light irradiated to the second section 22 can cause the second section 22 to generate heat and transfer it to the aerosol matrix 200. In addition, part of the light that passes through the first tube 10 can directly cause the second section 22 to generate heat and then transfer it to the aerosol matrix 200, and part of the light that passes through the second section 22 continues to irradiate the aerosol matrix 200, so that the aerosol matrix 200 can generate heat.

[0096] In some embodiments, the first section 21 is provided with a vent 211, and the heat storage component 40 has a connecting hole, which is used to communicate with the vent 211 and the interior of the second section 22. Among them, the vent 211 can be connected to the outside world. It is understandable that when the aerosol matrix 200 in the second section 22 is atomized, the mist can be sucked from the side of the second section 22 away from the first section 21. External air can enter the connecting hole inside the heat storage component 40 through the vent 211, and then enter the interior of the second section 22, which is convenient for sucking the mist atomized by the aerosol matrix 200 and avoiding the generation of negative pressure in the second section 22. In addition, when the external air passes through the connecting hole, the heat storage component 40 can preheat the external air, so that the heat stored in the heat storage component 40 can be utilized.

[0097] It should be noted that the communicating holes of the heat storage member 40 may be internal micropores, and the micropores inside the heat storage member 40 are interconnected, so that air can pass through the heat storage member 40. Optionally, the heat storage member 40 may be a porous material. Exemplarily, the heat storage member 40 may be porous graphite. Exemplarily, the heat storage member 40 may be a heat storage member 40 made of graphite or other materials with communicating holes.

[0098] See also Fig.19 In some embodiments, the heat storage component 40 includes a main body 41 and an extension portion 42, at least a portion of the main body 41 is located in the first section 21, the extension portion 42 is connected to the main body 41, and at least a portion of the extension portion 42 is located in the second section 22, and the extension portion 42 is located between the aerosol matrix 200 and the wall of the second section 22.

[0099] It can be understood that the extension portion 42 can increase the surface area of ​​the heat storage component 40, thereby increasing the heating area and further improving the heat storage efficiency.

[0100] Please also read Fig. 20 and Fig.21In some embodiments, the extension portion 42 can move between a first position and a second position along the axial direction of the second tube 20. When the extension portion 42 is in the first position, at least a portion of the extension portion 42 is located in the second section 22. When the extension portion 42 is in the second position, at least a portion of the extension portion 42 is located in the first section 21. In this way, when the heat pipe 100 is not installed with the aerosol matrix 200, the extension portion 42 can be in the first position, which can increase the surface area of ​​the heat storage member 40, thereby increasing the heating area and further improving the heat storage efficiency. In addition, when the heat pipe 100 is installed with the aerosol matrix 200, the extension portion 42 can be in the second position without affecting the installation of the aerosol matrix 200.

[0101] Optionally, the main body 41 is provided with a slideway 401 , and the extension portion 42 can slide along the slideway 401 .

[0102] Optionally, the heat storage member 40 further includes an elastic member 43, which is located in the slideway 401 and connects the extension portion 42 and the main body 41. When the heat pipe 100 is installed with the aerosol matrix 200, the aerosol matrix 200 squeezes the extension portion 42, and the extension portion 42 is in the second position, and the elastic member 43 can be elastically deformed.
