Please refer to Figure 1. The first aspect of the embodiment of the present application provides a planar heating structure, including: a heating plate assembly. The heating plate assembly includes: a heating plate 1 and an electrical connection portion 2. The electrical connection portion 2 is connected to the heating plate 1; the electrical connection portion 2 and the heating plate 1 are located on the same plane. Among them, the electrical connection portion 2 serves as the electrical input end of the heating plate 1, corresponding to the two poles of the power supply that the heating plate 1 needs to be connected to. In the heating plate assembly, the electrical connection portion 2 can include two, and they are respectively arranged at the two ends of the heating plate 1.

In this embodiment, the heating sheet 1 is in the shape of a flat sheet, and the heating sheet 1 can be made of iron-chromium alloy or other resistance alloy materials.

In this solution, the heating sheet 1 and the two electrical connection parts 2 are all located on the same plane, and the three together constitute a planar heating structure, which can be used to heat the atomized liquid without going through a winding process. The planar heating structure has the advantages of simple assembly and high efficiency, which is more conducive to the consistency of product production and helps to improve production efficiency.

It should be noted that in existing atomizers, the heating sheet wound into a cylindrical shape is structurally unstable and easily deformed. In this embodiment, the planar heating sheet 1 and the electrical connection portion 2 can effectively improve the stability of the heating structure and help extend the service life of the atomizer.

As an embodiment, the electrical connection portion 4 may be in a sheet shape.

Specifically, in existing heating sheets that require winding, the heating sheet generally uses strip-shaped pins as the electrical input terminal. In this embodiment, the electrical connection portion 4 and the heating sheet 1 are both sheet-shaped, which facilitates the planarization of the overall structure of the heating sheet assembly and facilitates the connection of connectors in actual applications; for example, the frame 2 in the following embodiment can be fixedly connected to the sheet-shaped electrical connection portion 4.

Furthermore, in existing heating sheets that require winding, the strip-shaped pins need to be welded to achieve pin fixation. In this embodiment, the sheet-shaped electrical connection portion 4 has a wider contact surface and can be fixed in the shell of the atomizer without welding, thereby further simplifying the assembly process.

In a more specific embodiment, please refer to Figure 1 or Figure 2; the heating sheet 1 can be in the shape of a mesh sheet and is provided with heating strips 12 extending outwardly along a first direction. The outwardly extending heating strips 12 are used to increase the heating area of the heating sheet 1.

Taking the two electrical connection parts 4 as an example, which are arranged vertically, in the embodiment shown in Figure 1, the first direction can be the y direction, that is, the heating strip 12 on the heating plate 1 extends in the horizontal direction; in the embodiment shown in Figure 2, the first direction can be the x direction, that is, the heating strip 12 on the heating plate 1 extends in the vertical direction.

When the first direction is horizontal, as shown in Figure 1, the electrical connection portion 4 includes a first connection portion 41 and a second connection portion 42; the first connection portion 41 and the second connection portion 42 are vertically connected to each other; the first connection portion 41 is located at the side end of the heating plate 1 along the first direction; and the second connection portion 42 is connected to the end of the heating plate 1 along the second direction. In other words, in this embodiment, the electrical connection portion 4, through the first connection portion 41 and the second connection portion, forms a vertical structure for connecting the heating plate 1 in the vertical direction.

When the first direction is the vertical direction, as shown in FIG2 , both ends of the heating plate 1 along the horizontal direction can be directly connected to the electrical connection part 4 , which can simplify the structure of the electrical connection part 4 compared with the method shown in FIG1 .

It should be noted that the heating strips 12 on the heating sheet 1 extend in different directions, so that the heating sheet assembly can have different atomization effects.

In a further improved embodiment, referring to Figures 1 to 4, the heating plate assembly further includes: a frame 2; the heating plate 1 is sheet-shaped and is directly fixed on the frame 2 or fixed on the frame 2 through the electrical connection part 4; the frame 2 is hollow and has hollow holes on it.

The frame 2 can shape the heating sheet 1 to increase the structural strength of the sheet-like heating sheet 1 and prevent the heating sheet 1 from deforming.

The frame 2 can be used to install the liquid guide 3, so that the liquid guide 3 can pass through the hollow hole and abut against the heating plate 1. The liquid guide 3 is used to guide the atomized liquid in the atomizer to the heating plate 1.

The liquid guiding member 3 may be, for example, liquid guiding cotton, liquid guiding ceramic or a porous matrix, and specifically, the liquid guiding member can absorb the atomized liquid and guide it to the heating plate 1 .

By fixing the heating sheet 1 on the frame 2, the heating sheet 1 can maintain a flat surface. During use, the heating sheet 1 directly heats the atomized liquid in the liquid guide 3 without the need to wind the heating sheet 1, which can reduce the difficulty of operation and improve the efficiency of operation.

In a further improved embodiment, referring to Figures 3 to 5 , the heating element assembly further includes a connecting frame 5; the frame 2 is disposed on one side of the heating element 1, such as the front side of the heating element 1; and the connecting frame 5 is disposed on another side of the heating element 1, such as the rear side of the heating element 1. Similarly, the connecting frame 5 can be disposed directly on the heating element 1 or on the electrical connection portion 4.

The heating sheet 1, the electrical connection portion 4, and the connecting frame 5 can be integrally formed using an injection molding process, so that the heating sheet 1 is embedded in the connecting frame 5. By providing the frame 2 and the connecting frame 5 on both sides of the heating sheet 1, the rigidity of the heating sheet assembly can be further increased, thereby maintaining the heating sheet 1 in a flat, planar sheet shape, thereby ensuring that the heating sheet 1 can fully contact the liquid guide 3.

In one embodiment, two heating element assemblies can be connected and used together via a connecting frame 5. Specifically, the heating element assemblies include at least two connecting frames 5 disposed at both ends of the other end surface of the heating element 1, such that the middle portion of the other end surface of the heating element 1 is hollowed out. The two heating element assemblies are detachably connected via the connecting frame 5, meaning that the connecting frame 5 is configured to detachably connect to the connecting frame 5 of another heating element assembly.

Specifically, referring to Figures 5 and 6, the two heating sheet assemblies can be combined into one by a connecting frame 5. In the two heating sheet assemblies, a channel 6 is formed in the middle between the two heating sheets 1; in operation, when air flows through the channel 6, it mixes with the heated atomized liquid to form an aerosol.

In another embodiment, the connecting frame 5 can be detachably connected to another connecting frame 5 by providing a buckle 52 and/or a slot 51 on the connecting frame 5 for connecting to another connecting frame 5 .

Among them, the connecting frame 5 at both ends of the end surface of the other side of the heating plate 1 can be respectively provided with a buckle 52 and a slot 51, so that the two heating plate components can be assembled through the connecting frame 5.

Furthermore, thickened portions 11 are provided at both ends of the heating plate 1 ; the thickened portions 11 are used for fixedly connecting to the connecting frame 5 .

The thickened portion 11 can be formed by bending the heating strip 12 on the heating plate 1 , so that the heating plate 1 can be partially embedded in the connecting frame 5 , thereby better fixing the heating plate 1 and the connecting frame 5 .

A second aspect of the present application provides an atomizer core, comprising the planar heating structure in any of the above embodiments.

A third aspect of the present application provides an atomizer, comprising the planar heating structure in any one of the above embodiments.

Specifically, the atomizer may further include an outer shell and a battery core. The outer shell is provided with a liquid storage chamber for storing atomized liquid; a liquid storage sponge is disposed within the liquid storage chamber. The planar heating structure in the above embodiment is disposed within the outer shell and connected to the liquid storage sponge via a liquid guide 3, thereby directing the atomized liquid in the liquid storage chamber to the heating element 1. The battery core is electrically connected to the aforementioned electrical connection portion to power the heating element assembly.
