Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and in particular to a heating structure and an electronic atomization device. Background Technology
[0002] Electronic atomizing devices include a power supply unit and an atomizer. The power supply unit is electrically connected to the atomizer and supplies power to it. The atomizer has a reservoir for storing e-liquid and an atomizing coil that communicates with the liquid in the reservoir. The atomizing coil is used to heat and atomize the e-liquid to form an aerosol that the user can inhale. When used in low-temperature environments (such as outdoors in winter or at high altitudes), the e-liquid may become viscous, separate into layers, become cloudy, or even solidify due to the temperature drop. This reduces the fluidity of the e-liquid, leading to insufficient liquid supply to the atomizing coil, resulting in less aerosol generation, and even the problem of the atomizing coil burning out.
[0003] In related technologies, to address the aforementioned problems, a heating structure is incorporated within the atomizer to preheat the atomized liquid, thereby increasing its temperature, reducing its viscosity, and ultimately improving its flowability. However, the heating structure has a low degree of modularity and needs to be integrated within the atomizer, resulting in a complex structure. Furthermore, when the atomizer is a disposable consumable, the heating structure is difficult to recycle, thus increasing the atomizer's operating costs. Utility Model Content

[0045] Reference Figures 1 to 10 According to an embodiment of the present application, the heating structure is disposed outside the atomizer a and independent of the atomizer a, wherein the heating structure includes a heat insulation member 100 and a heating element 200.
[0046] Specifically, the heating element 200 is fixedly disposed on one side of the heat insulation component 100, and the side of the heating element 200 facing away from the heat insulation component 100 is provided with a heating part 210 for direct or indirect contact with the atomizer a.
[0047] In use, the heating structure is disposed outside the atomizer a and independent of the atomizer a. Specifically, the heating element 210 is in direct or indirect contact with the atomizer a, so that the heating element 210 can heat the liquid storage chamber b of the atomizer a during operation to preheat the atomized liquid. This increases the temperature of the atomized liquid, reduces its viscosity, and improves its fluidity. This helps reduce the amount of aerosol generated due to insufficient liquid supply to the atomizer core c of the atomizer a, and also reduces the problem of dry burning of the atomizer core c. The heat insulation element 100 is used to reduce heat loss and protect non-heated targets. Compared to the case where the heating structure is integrated into the atomizer a, the heating structure of this embodiment has a higher degree of modularity, which simplifies the structure of the atomizer a. When the atomizer a is a disposable consumable, it helps reduce the usage cost of the atomizer a.
[0048] Specifically, the heat insulation component 100 helps to prevent the heat generated by the heating element 210 during operation from being transferred to the side of the heating element 210 facing away from the atomizer a. This allows the heat generated by the heating element 210 to be primarily conducted to the atomizer a, thereby reducing heat loss and improving heat utilization, which in turn helps to reduce the power consumption of the heating element 200. In addition, the heat insulation component 100 also helps to prevent damage to areas of non-heated targets near the heating element 210 due to overheating.
[0049] Reference Figure 1 , Figure 2 as well as Figures 4 to 8 In some embodiments, the heating element 200 is a flexible structural component, comprising a flexible substrate 220 and a heating coating disposed on the flexible substrate 220. The portion of the flexible substrate 220 with the heating coating that is in direct or indirect contact with the atomizer a constitutes the heating element 210. The flexible structure of the heating element 200 allows it to be bent, enabling it to adapt to the shape of the atomizer a and allowing the heating element 210 to better contact the atomizer a directly or indirectly.
[0050] Specifically, the heating coating can be made by applying an electrothermal coating.
[0051] Specifically, the heating element 200 can be an FPC heating element, that is, a flexible circuit board with heating circuitry.
[0052] Reference Figures 3 to 8 In some embodiments, the heating structure further includes a heat spreader 300, which is fixedly disposed on the heat insulation member 100. The heat spreader 300 has a heat-conducting portion 310, and the heating portion 210 is sandwiched between the heat insulation member 100 and the heat-conducting portion 310. The heat-conducting portion 310 helps to improve the heat transfer efficiency between the heating structure and the atomizer a, and also helps to ensure uniform heat transfer.
[0053] Specifically, the heat spreader 300 is a metal structural component.
[0054] In some embodiments, the heat insulation component 100 is an elastic silicone or rubber structural component. After the heating structure is assembled, the heat insulation component 100 can provide an elastic force that causes the heat-conducting part 310 to adhere to the atomizer a through an interference fit assembly method. Based on this, the heat insulation component 100 can also provide an elastic force that causes the heat-conducting part 310 to adhere to the heating part 210, thereby improving the heat transfer efficiency.
[0055] Reference Figures 4 to 8In some embodiments, the heating element 200 and the heat spreader 300 are both sheet-like, and the heating element 200, the heat spreader 300 and the heat insulation element 100 are detachably connected so that any one of the heating element 200, the heat spreader 300 and the heat insulation element 100 can be replaced as needed.
[0056] Reference Figures 4 to 8 In some embodiments, the heat insulation component 100 includes a heat insulation body 110 and ears 120. Ears 120 are provided on opposite sides of the heat insulation body 110, and a perforation 130 is formed between each ear 120 and the heat insulation body 110. The heat spreader 300 also includes fixing portions 320. Fixing portions 320 are provided on opposite sides of the heat conduction portion 310. Each fixing portion 320 is correspondingly inserted into each perforation 130, and each fixing portion 320 is arranged correspondingly to each ear 120. The heating element 210 is sandwiched between the heat insulation body 110 and the heat conduction portion 310, thereby enabling a detachable connection between the heating element 200, the heat spreader 300, and the heat insulation component 100. This structure is simple and easy to implement. Furthermore, this connection method allows for better contact between the heating element 210 and the heat conduction portion 310, resulting in better heat transfer.
[0057] It should be noted that in some other embodiments, the heating element 200, the heat spreader 300, and the heat insulation element 100 can also be detachably connected by a snap-fit structure or screws, which is not limited here.
[0058] Reference Figure 5 , Figure 9 and Figure 10 In some embodiments, at least a portion of the heat insulation body 110 protrudes from the side of the ear portion 120 away from the fixing portion 320 on the side facing the heating portion 210, so that the heat insulation body 110 can better press the heating portion 210 against the heat-conducting portion 310, thereby improving the fit between the heating portion 210 and the heat-conducting portion 310, and thus improving the heat transfer efficiency and heat transfer uniformity between the two.
[0059] Reference Figures 6 to 8 as well as Figure 10 In some embodiments, the ear portion 120 is located on opposite sides of the heat insulation body 110 along a first direction. The heat insulation body 110 is provided with a cutting groove 140 extending along the first direction, so that the heat insulation body 110 forms a first portion 111 and a second portion 112 that can be folded relative to the ear portion 120 in a direction intersecting the first direction. When it is necessary to assemble the heating element 200 and the heat spreader 300 on the heat insulation member 100, force can be applied to drive the first portion 111 and the second portion 112 to fold open relative to the ear portion 120, so as to facilitate the assembly of the heating element 200 and the heat spreader 300, thereby reducing the assembly difficulty and improving the assembly efficiency.
[0060] It should be noted that the first direction mentioned above is the X direction in the attached diagram.
[0061] When the heat insulation component 100 is an elastic silicone or rubber structure, the deformation generated during the folding and opening of the first part 111 and the second part 112 relative to the ear 120 is elastic deformation. During the assembly of the heating element 200 and the heat spreader 300, after the force is applied to drive the first part 111 and the second part 112 to fold and open relative to the ear 120 and place the heating element 200 and the heat spreader 300, the external force applied to the first part 111 and the second part 112 is removed, and the first part 111 and the second part 112 can automatically return to the state before folding and opening relative to the ear 120 to fix the heating element 200 and the heat spreader 300.
[0062] In some embodiments, the heat insulation body 110 is provided with a heat insulation structure on the side facing the heating element 210. The heat insulation structure is used to prevent the heat generated by the heating element 210 when it is working from being conducted to the heat insulation body 110. This helps to prevent the heat generated by the heating element 210 when it is working from being transferred to the side of the heating element 210 away from the heat conduction part 310, so that the heat generated by the heating element 210 when it is working can be mainly conducted to the heat conduction part 310. This helps to reduce heat loss and improve heat utilization, thereby helping to reduce the power consumption of the heating element 200.
[0063] Reference Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 10 In some embodiments, the heat insulation structure includes a groove 150 disposed on the side of the heat insulation body 110 facing the heating element 210, the groove 150 and the heating element 210 enclosing a cavity d for heat insulation. On the one hand, by providing the groove 150, the contact area between the heating element 210 and the heat insulation body 110 can be reduced, which is beneficial to reducing the heat transfer efficiency between the heating element 210 and the heat insulation body 110, thereby reducing heat loss; on the other hand, the air filled in the cavity d formed by the groove 150 and the heating element 210 has a heat insulation effect, which is beneficial to further reduce heat loss.
[0064] Reference Figure 5 and Figure 9In some embodiments, there are multiple grooves 150, which are spaced apart. Compared to the case of only one large groove 150, setting multiple smaller grooves 150 helps to enhance the structural strength of the heat insulation body 110, making the cavity d formed by the grooves 150 and the heating part 210 less likely to collapse due to compression after assembly, thereby helping to ensure the heat insulation effect of the heat insulation structure.
[0065] Reference Figure 7 and Figure 10 In some other embodiments, the number of grooves 150 is one.
[0066] Reference Figure 7 and Figure 10 In some embodiments, at least one protrusion 160 is provided in the groove 150 to abut against the heating part 210. The protrusion 160 is beneficial to enhance the structural strength of the heat insulation body 110, so that the cavity d formed by the groove 150 and the heating part 210 is not easy to collapse due to compression after assembly, thereby helping to ensure the heat insulation effect of the heat insulation structure.
[0067] Reference Figure 4 , Figure 5 and Figure 8 In some embodiments, the fixing part 320 is provided with a protruding positioning part 321 on the side opposite to the ear part 120, and the heating element 200 is provided with a limiting hole 230 for positioning in conjunction with the positioning part 321. When assembling the heating structure, the positional relationship between the heating element 200 and the heat spreader 300 can be limited by the cooperation between the positioning part 321 and the limiting hole 230, which helps to reduce the assembly difficulty and thus improve the assembly efficiency.

The atomizer a is provided with a liquid storage chamber b and an atomizing core c that is in liquid communication with the liquid storage chamber b. The heating element 210 is used to heat the liquid storage chamber b, and at least a portion of the liquid storage chamber b is correspondingly provided with the heating element 210.
[0069] It should be noted that since the electronic atomizing device of the embodiments of this application includes the heating structure described above, the electronic atomizing device of the embodiments of this application includes all the technical effects of the heating structure described above.
