DETAILED DESCRIPTION

[0042] The present invention 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.

[0043] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0044] 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).

[0045] In the present application, the atomization device is an electric heating atomization device, or a heat-not-burn atomization device, which is used to heat a heating element to generate an aerosol or atomizer. The atomization device can be a heat-not-burn smoking device, a solid aromatherapy machine, or a solid medicine atomization device, etc.

[0046] The heated part contains an aerosol matrix, which is heated and atomized to produce an aerosol. The heated part is determined according to the implementation mode of the atomization device. For example, when the atomization device is a heat-not-burn smoking device, the heated part corresponds to a cigarette or a cigarette cartridge. Of course, the above examples are only to illustrate the implementable methods, and do not limit the atomization device to a heat-not-burn smoking device. This application is only for the convenience of description, and takes the heat-not-burn smoking device as an example. At this time, the heated part is a solid cigarette or a cigarette cartridge. When it corresponds to a drug atomization device, the heated part is a solid part containing a drug.

[0047] In the present application, the heat insulating member is a component, part or part that reduces heat radiation, heat conduction or heat convection. The specific shape is not limited and is matched according to the internal structure of the actual atomizing device, such as a round tube, a square tube, or an inner round and outer square. In the embodiment of the present application, the heat insulating member is described by taking a tube as an example, and the heat insulating member can also be called a heat insulating tube.

[0048] In the present application, the operating temperature is determined by the material of the thermal insulation component. For example, for metal materials, the maximum operating temperature corresponds to its oxidation temperature; for organic materials, the maximum operating temperature corresponds to the aging temperature, deformation temperature, deformation temperature or melting point, etc.; once the maximum operating temperature is exceeded, the thermal insulation performance of the thermal insulation component will be reduced.

[0049] like Figures 1 to 3 As shown, the embodiment of the present application provides an atomizer assembly 100 , which may include: a bracket assembly 10 , a heating element 20 , a first thermal insulation member 30 , a second thermal insulation member 40 and a third thermal insulation member 50 .

[0050] The heating element 20 has a hollow area for accommodating the heated component 400 to pass through; the bracket assembly 10 has an opening structure matching the hollow area, and the heated component 400 can extend into the hollow area through the opening structure. The heating element 20 can be implemented by a heating tube or a heating net to heat the periphery of the heated component 400.

[0051] The heating element 20, the first thermal insulation member 30, the second thermal insulation member 40 and the third thermal insulation member 50 are respectively fixed on the bracket assembly 10; for example, the heating element 20, the first thermal insulation member 30, the second thermal insulation member 40 and the third thermal insulation member 50 can be fixed to the bracket assembly 10 by means of an embedded jacket, or by means of auxiliary parts such as screws and clamps, or by means of gluing.

[0052] The first thermal insulation member 30 is sleeved on the periphery of the heating element 20, the second thermal insulation member 40 is sleeved on the periphery of the first thermal insulation member 30, and the third thermal insulation member 50 is sleeved on the periphery of the second thermal insulation member 40; wherein, the maximum working temperature of the first thermal insulation member 30 is greater than the maximum working temperature of the second thermal insulation member 40; and the thermal conductivity coefficient of the second thermal insulation member 40 is less than the thermal conductivity coefficient of the first thermal insulation member 30.

[0053] All three thermal insulation components are made of high-temperature resistant materials. The first thermal insulation component 30 is closest to the heating element 20 and has the highest temperature there. Therefore, the maximum working temperature needs to be greater than the maximum working temperature of the second thermal insulation component 40. At the same time, the thermal conductivity of the second thermal insulation component 40 is smaller than that of the first thermal insulation component 30. Thermal insulation is mainly achieved by reducing heat conduction.

[0054] The triple heat-insulating set is arranged on the outer periphery of the heating element 20, so as to provide good heat insulation for the heating element 20, thereby ensuring that the temperature of the outer shell 300 is relatively low when the user holds the atomizing device.

[0055] like Figure 2 and Figure 3 As shown, in one embodiment, the bracket assembly 10 may include an upper bracket 11 and a lower bracket 12; the heating element 20, the first thermal insulation member 30, the second thermal insulation member 40 and the third thermal insulation member 50 are respectively fixed between the upper bracket 11 and the lower bracket 12; the two ends of the heating element 20 are respectively fixed by the upper bracket 11 and the lower bracket 12, and the middle area of ​​the heating element 20 is suspended.

[0056] The temperature at both ends of the heating element 20 is lower than that in the middle area. By fixing the two ends of the heating element 20 and using upper and lower split brackets, three heat insulating components can be conveniently installed on the periphery of the heating element 20.

[0057] like Figure 4 As shown, in one embodiment, there is a gap between the first thermal insulation member 30 and the heating element 20 , there is a gap between the second thermal insulation member 40 and the first thermal insulation member 30 , and there is a gap between the third thermal insulation member 50 and the second thermal insulation member 40 .

[0058] Air is a good thermal insulation medium. Multiple layers of air gaps can be formed through three thermal insulation components to avoid heat conduction due to direct contact between the thermal insulation components. Air is used for further thermal insulation to improve the thermal insulation effect.

[0059] like Figures 1 to 8 As shown, in one embodiment, the heating element 20 can be a heating tube; for example, in heat-not-burn smoking devices, there are heating methods using heating needles or heating tubes. In the present application, the implementation method of the specific atomization device is not limited, and the method using a heating tube is more applicable.

[0060] like Figure 6 and Figure 8 As shown, the lower bracket 12 has a first mounting portion 121 that matches one end of the heating element 20. Figure 5 and Figure 7 As shown, the upper bracket 11 has a second mounting portion 111 matching the other end of the heating element 20 .

[0061] like Figure 6 and Figure 8 As shown, the lower bracket 12 has a third mounting portion 122 that matches one end of the first heat insulating member 30. Figure 5 and Figure 7 As shown, the upper bracket 11 has a fourth mounting portion 112 matching the other end portion of the first heat insulating member 30 .

[0062] like Figure 3 As shown, both ends of the gap area between the heating element 20 and the first thermal insulation member 30 are blocked by the upper bracket 11 and the lower bracket 12. Some heating tubes are complete tubular structures without hollow structures such as holes and grooves on the side walls. In this case, both ends of the gap area between the heating tube and the first thermal insulation member 30 are blocked by the upper bracket 11 and the lower bracket 12 to form a closed area. At this time, heat convection is weakened, which can further improve the thermal insulation effect.

[0063] Some heating tubes have a hollow structure. In this case, both ends of the first thermal insulation member 30 are blocked, and no air flows to the second thermal insulation member 40. This also reduces heat convection to a certain extent and improves the thermal insulation effect.

[0064] like Figure 2 and Figure 4 As shown, in one embodiment, the inner side surface of the second thermal insulation member 40 has a positioning protrusion 41, and the positioning protrusion 41 abuts against the outer side surface of the first thermal insulation member 30, so that the first thermal insulation member 30 and the second thermal insulation member 40 are relatively fixed in the radial direction.

[0065] like Figure 5 and Figure 6 As shown, at this time, the second thermal insulation member 40 does not need to be provided with the fifth mounting portion 123 and the sixth mounting portion 113 on the lower bracket 12 and the upper bracket 11, and the second thermal insulation member 40 is radially positioned by means of the first thermal insulation member 30. The positioning protrusion 41 can be arranged along the axial direction or along the circumferential direction. At this time, the first thermal insulation member 30 and the second thermal insulation member 40 are partially in contact, not completely in contact, and the air medium is also used to achieve thermal insulation. The positioning protrusion 41 can reduce the portion of heat conduction between the first thermal insulation member 30 and the second thermal insulation member 40.

[0066] like Figure 7 and Figure 8 As shown, in one embodiment, the lower bracket 12 has a third mounting portion 122 matching one end of the first thermal insulation member 30, and the upper bracket 11 has a fourth mounting portion 112 matching the other end of the first thermal insulation member 30; the lower bracket 12 has a fifth mounting portion 123 matching one end of the second thermal insulation member 40, and the upper bracket 11 has a sixth mounting portion 113 matching the other end of the second thermal insulation member 40; both ends of the gap area between the first thermal insulation member 30 and the second thermal insulation member 40 are blocked by the upper bracket 11 and the lower bracket 12 to form a closed area.

[0067] At this time, there is no contact between the first thermal insulation member 30 and the second thermal insulation member 40, and thermal insulation is achieved by the air medium. There is no direct contact heat conduction, and a better thermal insulation effect can be achieved.

[0068] like Figures 5 to 8 As shown, in one embodiment, the lower bracket 12 has a fifth mounting portion 123 matching one end of the second thermal insulation member 40, and the upper bracket 11 has a sixth mounting portion 113 matching the other end of the second thermal insulation member 40; the lower bracket 12 has a seventh mounting portion 124 matching one end of the third thermal insulation member 50, and the upper bracket 11 has an eighth mounting portion 126 matching the other end of the third thermal insulation member 50; both ends of the gap area between the second thermal insulation member 40 and the third thermal insulation member 50 are blocked by the upper bracket 11 and the lower bracket 12 to form a closed area.

[0069] At this time, the second thermal insulation member 40 and the third thermal insulation member 50 are completely not in contact with each other, and thermal insulation is achieved by the air medium. There is no direct contact heat conduction, and a better thermal insulation effect can be achieved.

[0070] It should be noted that the specific implementation method of the first mounting part 121 to the eighth mounting part 114 in the embodiment of the present application is determined according to the structure of the three thermal insulation components and the heating element 20. It can be fixed by an embedded outer sleeve or by other fixing methods, so that the heating element 20, the first thermal insulation component 30, the second thermal insulation component 40 and the third thermal insulation component 50 are respectively fixed on the bracket assembly 10.

[0071] In one embodiment, the material of the first thermal insulation member 30 may be metal or alloy, the inner side surface of the first thermal insulation member 30 may be a smooth surface, which is used to reflect the thermal radiation generated by the heating element 20; and / or, the material of the second thermal insulation member 40 may be a high temperature resistant non-metal.

[0072] For example, the first heat insulating member 30 may be made of aluminum alloy, or may be made of various metal materials such as stainless steel, copper or zinc, etc. Metal materials can be processed to form a smooth surface, have strong heat resistance, and can achieve effective reflection of thermal radiation.

[0073] For another example, the second thermal insulation member 40 can be a high temperature resistant plastic (ABS / PC / ABS+PC / nylon / PEEK / PPS, etc.), or other high temperature resistant materials: ceramics, aerogel, silica, mica, carbon or carbon fiber, etc. The second thermal insulation member 40 is located relatively far from the heating element 20 and has a relatively low temperature, so non-metallic materials can be used for thermal insulation, mainly by insulating heat in the form of heat conduction.

[0074] In one embodiment, the material of the third thermal insulation member 50 may be high temperature resistant plastic, metal or alloy; and / or, the inner side surface of the third thermal insulation member 50 may be a smooth surface, which is used to reflect the thermal radiation generated by the heating element 20.

[0075] After the first thermal insulation member 30 and the second thermal insulation member 40 and the air gap therebetween are used for thermal insulation, the heat generated by thermal conduction and thermal convection is already less, and thermal insulation can be performed by reflecting the thermal radiation generated by the heating element 20. It should be noted that although the thermal radiation reflected by the third thermal insulation member 50 comes from the second thermal insulation member 40, in fact, the heat of the second thermal insulation member 40 is actually generated after being heated by the heating element 20, so the thermal radiation actually reflected by the third thermal insulation member 50 comes from the heating element 20.

[0076] At this time, since the temperature of the third thermal insulation member 50 is relatively low, the reflection of thermal radiation can be achieved in the form of metal or non-metal.

[0077] like Fig. 9 and Fig.10 As shown, an embodiment of the present application further provides an atomization device, which may include: an inner shell 200, an outer shell 300, and the atomization assembly 100 described in the above embodiment.

[0078] The atomizer assembly 100 is arranged inside the inner shell 200; the outer shell 300 is sleeved inside the inner shell 200; the inner shell 200 and the outer shell 300 corresponding to the heating body 20 also have a matching opening structure, so that the heating element 400 can be installed in the atomizer device for heating.

[0079] In some embodiments, the atomization device may further include a power supply component and a button component, etc. The power supply component is used to supply power to the heating element 20. The button component can trigger and control the power supply component to supply power. The power supply component may include a battery and a circuit board.

[0080] like Fig. 9 and Fig.10 As shown on the right side of the figure, the user generally holds the side wall of the atomizer, and there is a gap between the outer side surface of the inner shell 200 and the inner side surface of the outer shell 300, and the gap can play a role in heat insulation.

[0081] In summary, when the heating element 20 starts to heat up, the first thermal insulation member 30 on the periphery of the heating element 20 radiates the heat to form the first layer of thermal insulation; then the second thermal insulation member 40 outside conducts the heat and radiates the heat to form the second layer of thermal insulation; the third thermal insulation member 50 installed on the outer diameter of the second thermal insulation member 40 reflects the heat radiated from the inside again to form the third layer of thermal insulation; these three layers of space are all enclosed spaces between the upper bracket 11 and the lower bracket 12, which avoids convective heat transfer and reduces heat transfer to the outside. The inner shell 200 and the outer shell 300 on the periphery of the atomizer assembly 100 form the fourth and fifth layers of thermal insulation. At this point, up to 5 layers of thermal insulation solutions are implemented to ensure that the surface temperature of the equipment is as low as the user can accept.

[0082] The atomization assembly 100 and the atomization device provided in the embodiment of the present application have at least the following technical effects:

[0083] 1. Use low-cost parts to achieve multiple thermal insulation effects, greatly reducing costs.

[0084] 2. The tubular thermal insulation component has a simple structure and is easy to implement.

[0085] 3. It can achieve a temperature of up to 350° from the heating element 20 to less than 48° from the outer shell 300 in a narrow device, and the heat insulation effect is good.
