[0028] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] like Figures 1 to 3 As shown, as a first embodiment of the present application, a heat insulation structure 100 is disclosed, and the heat insulation structure 100 is applied to an electronic atomizer. The heat insulation structure 100 includes a heating tube 110, a heat insulation tube 120 and a housing 130. The heating tube 110 is provided with a heating patch, and the heating patch is arranged on the outside of the heating tube 110. The heating patch is energized to generate heat. The heat insulation tube 120 is sleeved on the outside of the heating tube 110, and the heat insulation tube 120 and the heating tube 110 are spaced apart from each other. The heat insulating tube 120 is provided with a plurality of abutting portions 140, and the abutting portions 140 are provided at abutting against the outer surface of the heat insulating tube 120. The abutting portions 140 are provided at a plurality of locations, and the abutting portions 140 are respectively abutting against the outer surface of the heat insulating tube 120, so that a plurality of heat insulating spaces are formed between the shell 130 and the heat insulating tube 120.

[0030] In this embodiment, the outer shell 130 is provided with abutting portions 140, and the abutting portions 140 are arranged to abut against the outer surface of the insulation tube 120, so that a plurality of insulation spaces are formed between the outer shell 130 and the insulation tube 120. In this way, when the heating tube 110 is powered on for heating, the heat source will first contact the inner surface of the insulation tube 120, and then be partially reflected into the heating tube 110 through the inner surface of the insulation tube 120, thereby increasing the use efficiency of the heat to a certain extent, and part of the heat will be transferred to the insulation tube 120. On the heat pipe 120, because the insulation pipe 120 and the shell 130 are abutted by the abutment portion 140, there are multiple insulation spaces between the shell 130 and the insulation pipe 120, that is, the shell 130 and the insulation pipe 120 are not fully contact assembled, and there is an insulation space for heat insulation. Compared with the existing full-contact assembled heating components and shells, the speed of heat diffusion is greatly reduced, and the shell 130 heats up slowly, which can maintain the long-term use of the electronic atomizer, and the situation of being hot to the touch is less likely to occur during long-term use. Among them, the shell 130 can be made of polyetheretherketone (PEEK) material to make it resistant to high temperatures.

[0031] Furthermore, the heat insulation structure 100 further includes a base 150, the shell 130 includes a first end 131 and a second end 132 that are far away from each other, the first end 131 of the shell 130 is used to insert a cigarette, one end of the base 150 is located inside the shell 130 and is abutted against the second end 132 of the shell 130, and the end of the base 150 located inside the shell 130 abuts against the heat insulation tube 120 so that the heat insulation tube 120 is fixed in the shell 130, and the base 150 is also provided with a cigarette abutting against the second end 132 of the shell 130. The end face of the heating tube 110 is respectively abutted against one end of the cigarette inserted into the shell 130 and the first end 131 of the heating tube 110 away from the shell 130; by setting a base 150, the base 150 is used to abut against the insulation tube 120, so that the insulation tube 120 can be fixed in the shell 130 to ensure that when the insulation structure 100 is in use, the insulation tube 120 can always be covered by the abutment portion 140, avoiding the outer surface of the insulation tube 120 from contacting the remaining inner surface area of ​​the shell 130 to form a heat transfer path, causing the temperature of the shell 130 to rise.

[0032] Specifically, the abutting portion 140 may be provided in the following two configurations, which are described below one by one:

[0033] The first arrangement of the abutment portion 140: Figure 4As shown, the abutting portion 140 is a plurality of first bosses 141 protruding from the inner surface of the shell 130, and the plurality of first bosses 141 are arranged at intervals so that there is a spacing area between the first bosses 141, and the length of the first boss 141 covers the setting of the heat insulation tube 120, so that when the heat insulation tube 120 abuts against the shell 130, the outer surface of the heat insulation tube 120 abuts against the first boss 141. In this way, when the heat insulation structure 100 of this embodiment is in operation, since the heat insulation tube 120 and the shell 130 are abutted and fixed by the first bosses 141, there is a spacing area between the plurality of first bosses 141, that is, in addition to the first bosses 141 transferring heat between the heat insulation tube 120 and the shell 130, the air in the spacing area will slow down the heat transfer efficiency between the heat insulation tube 120 and the shell 130 to a certain extent, thereby forming a heat insulation layer;

[0034] Compared with the existing full-contact assembly of heating components and shells, in the heat insulation structure 100 of this embodiment, there is only direct contact between the heat insulation tube 120 and the shell 130 through the first boss 141. The path that is most likely to form heat transfer between the heat insulation tube 120 and the shell 130 is through the first boss 141, which greatly reduces the speed of heat transfer in the heat insulation structure 100 and avoids the shell 130 of the electronic atomizer from being easily scalded during long-term use; at the same time, the cross-section of the first boss 141 along the axial direction of the heat insulation tube 120 is rectangular / trapezoidal / triangular / circular, and when the first boss 141 and the heat insulation tube 120 are in surface contact, then The cross section of the first boss 141 along the axial direction of the insulation tube 120 is rectangular or trapezoidal, and heat is transferred through the contact surface area between the first boss 141 and the insulation tube 120. When the first boss 141 and the insulation tube 120 are in line contact, the cross section of the first boss 141 along the axial direction of the insulation tube 120 is triangular or circular, and heat is transferred through the contact line area between the first boss 141 and the insulation tube 120. In this embodiment, the heat transfer efficiency of line contact is lower than the heat transfer efficiency of surface contact. Designers can select and design the cross section of the first boss 141 according to the heat transfer efficiency required by the electronic atomizer, and there is no restriction here. Among them, the first boss 141 is provided with X, and X is greater than or equal to 5 and less than or equal to 13, so as to avoid the situation where the number of the first bosses 141 is too large and the heat transfer efficiency is high, and also avoid the situation where the number of the first bosses 141 is too small and the insulation tube 120 is directly in contact with the inner surface of the shell 130.

[0035] The second arrangement of the abutting portion 140 is as follows: Figure 5As shown, the abutting portion 140 is a plurality of first bosses 141 protruding from the inner surface of the shell 130, and the plurality of first bosses 141 are connected to form a wavy surface, and the wavy surface abuts against the outer surface of the insulation tube 120. The length of the first boss 141 covers the insulation tube 120. The highest point of the wavy surface abuts against the outer surface of the insulation tube 120, and there is a spacing area between the lowest point of the wavy surface and the outer surface of the insulation tube 120, that is, the outer surface of the insulation tube 120 only forms a heat transfer path with the highest point of the wavy surface, and the insulation The heat of the heat pipe 120 will be transferred to the shell 130 through this path, and the air in the interval area will slow down the heat transfer efficiency between the heat-insulating pipe 120 and the shell 130 to a certain extent, forming a heat-insulating layer; compared with the existing full-contact assembly of heat-generating components and shells, the heat-insulating structure 100 of this embodiment, the heat-insulating pipe 120 and the shell 130 only have direct contact through the highest point of the wavy surface on the first boss 141, which greatly reduces the speed of heat transfer in the heat-insulating structure 100, and avoids the shell 130 of the electronic atomizer from being easily hot during long-term use. Among them, the distance from the end of the first boss 141 away from the shell 130 to the inner surface of the shell 130 is between 0.2 and 0.9 mm, so as to avoid the heat-insulating structure 100 occupying too much space due to the setting of the first boss 141, resulting in uneven space distribution in the heat-insulating structure 100.

[0036] Furthermore, the inner surface of the heat-insulating tube 120 is set to a smooth surface, so that when the heat-insulating tube 120 receives the heat emitted by the heating tube 110, it can better reflect the heat to improve the use efficiency of the heat, and the outer surface of the heat-insulating tube 120 can be set to a matte surface or a smooth surface. When the outer surface of the heat-insulating tube 120 is set to a smooth surface, the friction force of the heat-insulating tube 120 when contacting the first boss 141 is small, so when installing the heat-insulating tube 120, it is easier to install the heat-insulating tube 120 into the shell 130; and the outer surface of the heat-insulating tube 120 is set to a matte surface or a smooth surface. When the surface is matte, when the insulation tube 120 transfers heat to the outer shell 130, the heat dissipated from the outer shell 130 will have a lower heat reflection efficiency when passing through the outer surface of the insulation tube 120, and the heat will not be reflected on the outer shell 130, which can extend the use time of the electronic atomizer to a certain extent and delay the heating time of the outer shell 130; wherein, the thickness of the insulation tube 120 is between 0.1 and 0.2 mm, and the insulation tube 120 can be made of metals such as aluminum and stainless steel, so that it has a better heat conduction effect, thereby reflecting the heat to the heating tube 110.

[0037] like Figure 6As shown, as a second embodiment of the present application, an electronic atomizer 200 is disclosed, the electronic atomizer 200 includes a cigarette 160 and a heat insulation structure 100 as described in the above embodiment, and the heat insulation structure 100 is used to heat the cigarette 160. The electronic atomizer 200 of this embodiment is provided with an abutting portion on the outer shell, and the abutting portion is abutted against the outer surface of the insulation tube, so that a plurality of insulation spaces are formed between the outer shell and the insulation tube. In this way, when the heating tube is powered on to generate heat, the heat source will first contact the inner surface of the insulation tube, and then be partially reflected into the heating tube through the inner surface of the insulation tube, thereby increasing the efficiency of heat use to a certain extent, and part of the heat will be transferred to the insulation tube. Since the insulation tube and the outer shell are abutted by the abutting portion, there are a plurality of insulation spaces between the outer shell and the insulation tube, that is, the outer shell and the insulation tube are not fully contacted, and there is an insulation space for insulation, so the speed of heat diffusion is greatly reduced, the outer shell heats up slowly, and the electronic atomizer can be used for a long time, and it is less likely to become hot after long-term use.

[0038] It should be noted that the limitations on the various steps involved in this solution, without affecting the implementation of the specific solution, are not deemed to limit the order of the steps. The steps written in front can be executed first, or later, or even simultaneously. As long as this solution can be implemented, it should be deemed to fall within the scope of protection of this application.

[0039] It should be noted that the inventive concept of the present application can form a large number of embodiments, but the length of the application document is limited and it is impossible to list them one by one. Therefore, under the premise of no conflict, the embodiments or technical features described above can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effects will be enhanced.

[0040] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
