When the existing atomizer device is working, the temperature of the heating element is as high as 300°C. The heat of the heating element can easily leak out and be conducted to other parts, causing the temperature of other parts of the atomizer device to be high, especially the hand-held part of the atomizer device, which is too hot to touch, affecting the normal use of the atomizer device. Utility Model Content

[0003] The present application provides a heat insulator and an atomizing device, which can reduce the heat conduction to the outside and solve the problem of being unable to use due to excessive temperature.

[0004] The present application provides a thermal insulator, comprising a heating element, a first thermal insulation tube, a second thermal insulation tube and a connecting piece, wherein the heating element is used to generate heat for heating an atomized aerosol to form a matrix; the first thermal insulation tube is sleeved on the outside of the heating element to reflect the heat generated by the heating element; the second thermal insulation tube is sleeved on the outside of the first thermal insulation tube; the connecting piece is disposed between the first thermal insulation tube and the second thermal insulation tube to support and restrict the first thermal insulation tube.

[0005] In one embodiment, the connecting member includes a plurality of spaced-apart connecting portions, the plurality of connecting portions are evenly arranged around the circumference of the first thermal insulation tube, and a first gap is provided between two adjacent connecting portions.

[0006] In one embodiment, the connecting portion is extended along the direction of the extension length of the first thermal insulation tube.

[0007] In one embodiment, the first thermal insulation tube and the heating element are spaced apart to form a second gap, and the heat is conducted to the first thermal insulation tube through the second gap.

[0008] In one embodiment, a length of the second gap along the radial direction of the first thermal insulation tube ranges from 0.5 mm to 4 mm.

[0009] In one embodiment, a reflective surface is provided on the side of the first thermal insulation tube facing the heating element, and the reflective surface is used to reflect the heat to the heating element.

[0010] In one embodiment, the smoothness of the reflective surface is 0.1um-1.0um.

[0011] In one embodiment, the thickness of the first thermal insulation tube ranges from 0.04 mm to 0.15 mm; the thickness of the second thermal insulation tube ranges from 0.4 mm to 0.8 mm.

[0013] The present application provides an atomization device, comprising a host assembly and the heat insulator as described above.

[0014] According to the heat insulator in the above embodiment, it includes a heating element, a first insulation tube, a second insulation tube and a connecting piece. Since the first insulation tube is sleeved on the outside of the heating element and can reflect the heat generated by the heating element, the heat of the heating element is reduced from being transferred outward to other components, and the temperature of other components can be lowered. Since the second insulation tube is sleeved on the outside of the first insulation tube, the heat needs to pass through the first insulation tube and the second insulation tube in sequence before being transferred to other components, which increases the path for heat transfer outward and reduces the heat conducted to other components by the heating element. Since a connecting piece is provided between the first insulation tube and the second insulation tube, the heat at the heating element needs to pass through the first insulation tube and the connecting piece in sequence before being transferred to the second insulation tube, which further increases the path for heat transfer and effectively slows down the speed of heat transfer to the second insulation tube, thereby reducing the heat transferred outward from the heating element to other components, lowering the temperature of other components and preventing other components from affecting the use of the atomization device due to high temperature.

[0020] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0021] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0022] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0023] When the atomizer is working, the temperature of the heating element is as high as 300°C. The heat of the heating element can easily leak out and be conducted to other parts, causing the temperature of other parts of the atomizer to be high, especially the hand-held part of the atomizer, which is too hot to touch and affects the normal use of the atomizer. In the prior art, in order to solve this problem, vacuum tubes or aerogels are used for thermal insulation. The cost of using vacuum tubes for thermal insulation is too high, and the thickness of aerogel required for aerogel thermal insulation is relatively thick. The space for the atomizer is small, resulting in its installation and use being relatively limited, and the thermal insulation effect is not very ideal. In order to solve the above technical problems, the present application provides the following solutions.

[0024] The present application provides an atomization device, including a main unit component and a heat insulator. Part of the structure of the main unit component is recessed inward to form an installation cavity, and the heat insulator is arranged in the installation cavity. The arrangement of the heat insulator can reduce the heat transfer to the main unit component while ensuring that the aerosol-forming matrix is ​​effectively heated and atomized, thereby reducing the temperature of the main unit component.

[0025] The host assembly is a collection of related functional components that constitute the overall outline structure of the atomizer. The user can carry, operate and use the atomizer by holding the host assembly; for example, the host assembly 100 may include a main housing, a control assembly including a battery, and various pipes, etc. Usually, a plurality of cavities with different functions are arranged or formed in the host assembly, and the plurality of cavities include the above-mentioned installation cavity.

[0026] It should be noted that the aerosol-forming substrate can be a solid medium material, a semi-solid medium material or a liquid material that can produce volatile substances. Generally, based on the different forms of the materials, the aerosol-forming substrate can be packaged by packaging materials or placed in a container.

[0027] It should be further explained that the specific structure of the host assembly can refer to the prior art and will not be described in detail here. The following mainly describes the heat insulator and its related structures.

[0028] refer to Figure 1-4 The thermal insulator includes a heating element 100, a first thermal insulation tube 200, a second thermal insulation tube 300 and a connecting piece 400. The heating element 100 is used to generate heat for heating the atomized aerosol to form a matrix. The first thermal insulation tube 200 is sleeved on the outside of the heating element 100 to reflect the heat generated by the heating element 100. The second thermal insulation tube 300 is sleeved on the outside of the first thermal insulation tube 200. The connecting piece 400 is disposed between the first thermal insulation tube 200 and the second thermal insulation tube 300 to support and limit the first thermal insulation tube 200.

[0029] Part of the heat generated by the heating element 100 is transferred inward to the aerosol matrix, heating and atomizing the aerosol matrix to form an aerosol for use by users; the other part is transferred outward. Since the first insulation tube 200 is sleeved on the outside of the heating element 100 and can reflect the heat generated by the heating element 100 inward to the heating element 100, the heat transferred outward from the heating element 100 to other components is reduced, thereby lowering the temperature of other components; since the second insulation tube 300 is sleeved on the outside of the first insulation tube 200, the heat transferred outward needs to pass through the first insulation tube 200 and the second insulation tube 300 in sequence before it can be used by users. It can be transferred to other components, increasing the heat transfer path outward, and reducing the heat conducted from the heating element 100 to other components; since a connector 400 is provided between the first insulation tube 200 and the second insulation tube 300, the heat transferred outward needs to pass through the first insulation tube 200 and the connector 400 in sequence before it can be transferred to the second insulation tube 300, further increasing the heat transfer path, effectively slowing down the speed of heat transfer to the second insulation tube 300, thereby reducing the heat transferred from the heating element 100 to other components outward, lowering the temperature of other components, and preventing other components from affecting the use of the atomization device due to high temperature.

[0030] The heating element 100, the first thermal insulation tube 200 and the second thermal insulation tube 300 are all tubular structures of regular shape, having axial and radial directions, and both having an outer surface and an inner surface. The inward transfer mentioned above refers to the direction of transfer from the outer surface to the inner surface along the radial direction of the heating element 100, and the outward transfer refers to the direction of transfer from the inner surface to the outer surface along the radial direction of the heating element 100.

[0031] The heating element 100 can heat and atomize the aerosol-forming matrix placed inside it by means of resistance heating or electromagnetic heating. Of course, heating can also be achieved by other heating methods. This part of the content does not belong to the content protected by this application and will not be repeated here.

[0032] In order to reduce the heat transfer on the first insulation tube 200, the thickness of the first insulation tube 200 ranges from 0.04mm to 0.15mm. The smaller the thickness, the less heat it absorbs, the less heat it transfers to the outside, and the more it can reduce the temperature of the host component.

[0033] However, the reduction in thickness can easily cause deformation of the structure, which will affect the heat transfer and function realization. By placing the connecting piece 400 between the first insulation tube 200 and the second insulation tube 300, not only the heat transfer path is increased, but also the first insulation tube 200 can be restricted and fixed to avoid deformation, thereby providing the possibility of producing a thinner or ultra-thin first insulation tube 200.

[0034] In order to effectively reduce the heat transfer to the outside, an effective technical means is to use the first insulation tube 200 to reflect the heat. The side of the first insulation tube 200 facing the heating element 100 (the inner surface of the first insulation tube 200) is provided with a reflecting surface 210. The reflecting surface 210 is used to reflect the heat from the first insulation tube 200 to the heating element 100. Specifically, the reflecting surface 210 can make part of the heat transferred from the heating element 100 to the first insulation tube 200 return to the heating element 100 along the original path, which can reduce heat transfer and heat loss and improve the utilization rate of the heat of the heating element 100.

[0035] In order to improve the reflection efficiency, the smoothness of the side of the first insulation tube 200 facing the heating element 100 is 0.1um-1.0um. Preferably, the smoothness of the reflection surface 210 is 0.1um-1.0um. This smoothness requirement not only enables the reflection efficiency of the reflection surface 210 of the first insulation tube 200 to be improved, but also is easy to implement with the current processing technology, simple to produce, and saves production costs.

[0036] Since the first thermal insulation tube 200 needs to be easily polished to make its finish meet the above requirements, the first thermal insulation tube 200 is made of metal materials, such as aluminum, aluminum alloy, stainless steel, copper, zinc or other metal materials. The first thermal insulation tube 200 is preferably made of aluminum alloy, which is not only easy to obtain and low in cost, but also because aluminum alloy has good ductility and is easy to process, and can be prepared into an ultra-thin structure, which is convenient to meet the thickness requirements of the first thermal insulation tube 200.

[0037] refer to Figure 4 The connector 400 includes a plurality of spaced connection parts 410, which are evenly arranged around the circumference of the first thermal insulation tube 200, and a first gap 220 is provided between two adjacent connection parts 410. The connection parts 410 support and restrict the first thermal insulation tube 200, so that the first thermal insulation tube 200 is evenly stressed in the circumferential direction, and its deformation is prevented from affecting the realization of the function. The connection parts 410 are used to increase the heat transfer path between the first thermal insulation tube 200 and the second thermal insulation tube 300, thereby reducing the temperature of the host assembly. The existence of the first gap 220 allows part of the heat to be conducted through the air in the first gap 220. Since the thermal conductivity coefficient of air is 0.0244 W / m·K, the thermal conductivity of air is poor, which is much smaller than the conductivity coefficient of solid. Therefore, the setting of the first gap 220 reduces the solid contact area between the first insulation tube 200 and the second insulation tube 300, reduces heat transfer, thereby reducing heat transfer to the outside, lowering the temperature of the main unit component, and also reducing the heat loss of the heating element 100, thereby improving the utilization rate of the heat generated by the heating element 100.

[0038] In order to effectively ensure the structural form of the first thermal insulation tube 200 and prevent its deformation, the connecting portion 410 is extended along the extension length direction of the first thermal insulation tube 200 , and the extension length of the connecting portion 410 is equal to the extension length of the first thermal insulation tube 200 .

[0039] In order to further reduce the heat transferred to the outside by the heating element 100, based on the principle of poor thermal conductivity of air, the first insulation tube 200 is spaced apart from the heating element 100 to form a second gap 420. Heat is conducted to the first insulation tube 200 through the second gap 420. The air in the second gap 420 conducts the heat generated by the heating element 100 to the first insulation tube 200, thereby reducing the heat transferred to the outside. The setting of the second gap 420 can also increase the heat transfer path, slow down the speed of heat transfer to the outside, and effectively ensure the thermal insulation effect.

[0040] The radial length of the second gap 420 along the first insulation tube 200 ranges from 0.5mm to 4mm, which can not only meet the limited space installation requirements in the atomization device, but also effectively ensure the reflection effect, reduce the heat transfer speed and reduce the transfer amount.

[0041] The function of the second thermal insulation tube 300 is to further reduce the heat transfer to the outside and avoid the second thermal tube from failing due to high temperature. High temperature resistant materials with low thermal conductivity can be selected, such as high temperature resistant plastics (ABS / PC / ABS+PC / nylon / PEEK / PPS, etc.), or other high temperature resistant materials such as ceramics, aerogel, silica, mica, carbon, carbon fiber, etc. The thermal conductivity of the second thermal insulation tube 300 ranges from 0.01w / m·k to 0.4w / m·k.

[0042] In order to further reduce the heat transfer to the outside, the thickness of the second insulation tube 300 is in the range of 0.4 mm-0.8 mm, which can reduce the heat energy absorbed by the second insulation tube 300.

[0043] In order to further reduce the secondary heat radiation of the first insulation tube 200 and reduce the heat transfer to the outside, the inner surface of the second insulation tube 300 is also polished, which can reflect the heat of the secondary heat radiation of the first insulation tube 200 back. The smoothness of the inner surface of the second insulation tube 300 is above 0.3um.

[0044] Furthermore, the connector 400 and the second insulation tube 300 are an integrally formed structure, and through size and structure design, the outer surface of the first insulation tube 200 is abutted against the inner side of the connector 400, which can not only limit and fix the first insulation tube 200, but also facilitate assembly.

[0045] The heat insulator of the present application includes a heating element 100, a first heat-insulating tube 200, a second heat-insulating tube 300 and a connecting piece 400. The heating element 100, the first heat-insulating tube 200, the connecting piece 400 and the second heat-insulating tube 300 are sequentially arranged from the inside to the outside, and the connecting piece 400 can not only support and limit the first heat-insulating tube 200, but also connect the first heat-insulating tube 200 and the second heat-insulating tube 300 into an integrated structure. The heating element 100 is directly installed in the inner cavity of the first heat-insulating tube 200, which has a simple structure, is easy to assemble, can reduce costs, and can be installed in a convenient manner. The first insulation tube 200 made of thin aluminum alloy and arranged on the outside of the heating element 100 can reduce heat transfer. Through the setting of the first gap 220, heat convection is used to reduce heat transfer. The second insulation tube 300 made of high-temperature resistant plastic with low thermal conductivity can reduce heat transfer again. Through the setting of the second gap 420, heat convection is further used to reduce heat transfer, thereby achieving the effect of thermal insulation, which not only reduces the temperature of the external host component and facilitates handholding, but also reduces heat loss and improves the utilization rate of the heat generated by the heating element 100.

[0046] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
