Description

Technical Field

[0001] This invention relates to the field of atomization device technology, and in particular to a multi-layer heating element structure and its atomization device. Background Technology

[0002] Aerosol generators typically heat the atomizing liquid using a heating mechanism to atomize it and produce aerosols. The characteristics of the heating mechanism and the atomizing liquid supply rate significantly affect the atomization effect. Existing atomization equipment utilizes various heating mechanisms with different structural designs, such as heating wires and heating films. However, existing heating mechanisms generally only provide heating and atomization functions, requiring additional design of a guiding medium and ventilation structure to ensure a uniform and constant supply of the atomizing liquid to the heating mechanism and to deliver the atomized aerosol to the user. Therefore, there is an urgent need to design a multi-functional heating mechanism that can provide ventilation, guide oil, and generate heat. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-layer heating element structure and its atomizing device to solve the technical problem that the heating mechanism of the existing atomizing device only has a single function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, embodiments of the present invention provide a multilayer heating element structure, comprising: a heating layer and a first coating layer; the heating layer has a plurality of microporous structures, the heating layer has a first atomizing surface, and the first coating layer is applied to the first atomizing surface such that the first atomizing surface is microporously sealed by the first coating layer.

[0006] The first coating also has several through holes, which expose part of the microporous structure.

[0007] The through holes are uniformly distributed on the first coating.

[0008] The first coating is an inorganic coating, an organic coating, or a metallic coating.

[0009] The micropore diameter of the microporous structure in the heating layer is 1µm-1mm.

[0010] The heating layer is a metal felt.

[0011] The heating layer further has a second atomizing surface disposed opposite to the first atomizing surface, and the second atomizing surface is provided with a second coating.

[0012] The first coating and / or the second coating are further provided with several through holes, so as to expose part of the microporous structure on the heating layer.

[0013] Secondly, this embodiment also provides another multilayer heating element structure, which includes: a heating layer and a coating layer, wherein the heating layer has a plurality of microporous structures, the heating layer has an atomizing surface, the coating layer is embedded in the heating layer, and the coating layer is disposed opposite to the atomizing surface; wherein the coating layer partially or completely covers the atomizing surface.

[0014] Thirdly, this embodiment also provides an atomizing device, which includes: a multi-layer heating element structure as described in any of the above.

[0015] The multi-layer heating element structure and its atomizing device of the present invention achieve ventilation, oil guiding and heating functions by setting a number of micropores in the heating layer, and set a sealing coating on one side, both sides or inside to appropriately reduce the number of micropores, avoid the generation of a large number of bubbles during the atomization process due to too many micropores, thereby reducing noise and improving the atomization effect and user experience.

[0029] Please see Figure 1 In this first embodiment, a multilayer heating element structure 100 is provided, comprising: a heating layer 11 and a first coating layer 12; the heating layer 11 has a plurality of microporous structures 111, and the heating layer 11 has a first atomizing surface, the first coating layer 12 being coated on the first atomizing surface, so that the first coating layer 12 microporously seals the first atomizing surface. In this embodiment, the first atomizing surface is disposed on the top surface of the heating layer 11, therefore the first coating layer 12 is coated on the top surface of the heating layer 11. If the multilayer heating element structure 100 is configured according to... Figure 1 The direction is assembled in the atomizing device. At this time, the heating layer 11 is located below the first coating layer 12. The atomizing liquid can be supplied from the side wall of the heating layer 11. The aerosol generated after atomization is released from the bottom surface of the heating layer 11 and output from the side perimeter.

[0030] Please see Figure 3 The first coating 12 is further provided with a plurality of through holes 121, thereby exposing a portion of the microporous structure 111. The through holes 121 allow partial exposure of the microporous structure 111, enabling the input of atomizing liquid and the output of aerosol through these holes. It is understood that the number and size of the through holes 121 can be determined according to the number of microporous structures 111 within the heating layer 11 and the thickness of the heating layer 11. The shape and size of the through holes 121 can be arbitrary, and their distribution can also be arbitrary.

[0031] To simplify the processing and atomization effect, in this first embodiment, the through holes 121 are evenly distributed on the first coating 12, and the through holes 121 are round holes.

[0032] The first coating 12 is an inorganic coating, an organic coating, or a metallic coating. The first coating 12 itself does not generate heat during atomization and has good sealing performance. It can block and seal some of the microporous structures 111 on the heating layer 11, thereby reducing the number of micropores. Microporous structures will generate bubbles during atomization, and the bursting of bubbles will generate noise. Therefore, reducing the microporous structure can reduce the number of bubbles and ultimately reduce atomization noise.

[0033] The micropore diameter of the microporous structure 111 within the heating layer 11 is 1µm-1mm. It is understood that in other embodiments, the micropore diameter of the microporous structure 111 may be larger or smaller, depending on the fabrication process of the heating layer 11 and the required atomization parameters.

[0034] In this embodiment, the heating layer 11 is a metal felt. Metal felt is a material with relatively mature existing technology, and there is no need to perform secondary processing on the material itself. The metal felt has many fine pores, which can penetrate the atomized liquid and allow air to pass through. In addition, the metal material has the characteristics of electric heating, microwave heating or electromagnetic induction heating.

[0035] Please see Figure 2 In this second embodiment, the multilayer heating element structure 200 includes: a heating layer 21 and a first coating layer 22; the heating layer 21 has a plurality of microporous structures 211, and the heating layer 21 has a first atomizing surface, and the first coating layer 22 is coated on the first atomizing surface, so that the first coating layer 22 microporously seals the first atomizing surface. In this embodiment, the first atomizing surface is disposed on the bottom surface of the heating layer 21, therefore the first coating layer 22 is coated on the bottom surface of the heating layer 21. If the multilayer heating element structure 200 is configured according to... Figure 2 The direction is assembled in the atomizing device. At this time, the heating layer 21 is located above the first coating layer 22. The atomizing liquid can be supplied from the top of the heating layer 21, and the aerosol generated after atomization is released from the top surface of the heating layer 21.

[0036] In this second embodiment, the multilayer heating element structure 200 differs from the multilayer heating element structure 100 in the relative positional relationship between the first coating layer and the heating layer. Similarly, the first coating layer 22 is also provided with several through holes, thereby exposing part of the microporous structure 211. In the second embodiment, the number, size, and shape of the through holes can be arbitrary. Preferably, the heating layer 21 is also a metal felt. Other structures are the same as in the first embodiment and will not be described in detail here.

[0037] Please see Figure 4 The multi-layer heating element structure 300 includes a heating layer 31, which further has a first atomizing surface and a second atomizing surface disposed opposite to each other. A second coating 33 is provided on the second atomizing surface, and a first coating 32 is provided on the first atomizing surface. The heating layer 31 contains a plurality of microporous structures 311 for ventilation or oil conduction. The first coating 32 and the second coating 33 can completely or partially cover their respective atomizing surfaces. When the atomizing surfaces are completely covered, ventilation and oil conduction can both occur through the sidewalls of the heating layer 31. If only partially covered, ventilation can occur through the uncovered portion.

[0038] Furthermore, the first coating 32 and / or the second coating 33 are provided with a plurality of through holes, thereby exposing a portion of the microporous structure 311 on the heating layer 31. Similar to the first embodiment and the second real-time method described above, the number, shape, and size of the through holes can be arbitrary, and can be appropriately selected according to the thickness or size of the heating layer 31. The other structures of the heating layer 31, the first coating 32, and the second coating 33 are the same as those in Embodiments 1 and 2 described above, and will not be repeated here.

[0039] Please refer to it again. Figure 5 This embodiment also provides a fourth implementation of a multilayer heating element structure, which includes: a heating layer and a coating 41. The heating layer has a plurality of microporous structures and an atomizing surface. The coating 41 is embedded in the heating layer and is disposed opposite to the atomizing surface; wherein the coating 41 partially or completely covers the atomizing surface. It should be noted that when the coating 41 completely covers the atomizing surface, arbitrary through holes can also be provided on the coating 41. The coating 41 is disposed approximately opposite to the atomizing surface, and the coating 41 can be a plane, a curved surface, or any other irregular surface.

[0040] This embodiment also provides an atomizing device, which includes a multi-layer heating element structure 100, a multi-layer heating element structure 200, a multi-layer heating element structure 300 or a multi-layer heating element structure 400 as described in any of the above.

[0041] The multi-layer heating element structure and its atomizing device of the present invention achieve ventilation, oil guiding and heating functions by setting a number of micropores in the heating layer, and set a sealing coating on one side, both sides or inside to appropriately reduce the number of micropores, avoid the generation of a large number of bubbles during the atomization process due to too many micropores, thereby reducing noise and improving the atomization effect and user experience.

[0042] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
