Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the implementation manners and the drawings. Herein, the illustrative implementation manners of the present utility model and their descriptions are used to explain the present utility model, but are not intended to limit the present utility model.

[0026] In the embodiments of the present disclosure, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] Figure 1 Structural schematic of the electrode head assembly of the beauty instrument provided by the embodiment of the present disclosure Figure 1 ; See Figure 1, an embodiment of the present disclosure provides an electrode head assembly, which includes: a housing 101, a central electrode 102, and N peripheral electrodes 103. The electrode positioning holes on the housing 101 are used to fix the central electrode 102 and the N peripheral electrodes 103, and at least a part of the exposed surface of the housing is flush with the end face of the electrode; the N peripheral electrodes 103 are rotationally symmetrically distributed around the geometric center of the central electrode 102; the polarities of the central electrode 102 and the peripheral electrodes 103 are opposite; the end face of the central electrode 102 is polygonal, and each vertex angle of the polygon corresponds to a peripheral electrode 103; in a state where the end faces of the central electrode 102 and the peripheral electrodes 103 are flush, the gaps between adjacent two peripheral electrodes 103 and the gaps between the peripheral electrodes 103 and the central electrode 102 are narrow strip-shaped.

[0028] In the above solution, the N peripheral electrodes are rotationally symmetrically distributed around the geometric center of the central electrode; the polarities of the central electrode and the peripheral electrodes are opposite; the end face of the central electrode is polygonal, and each vertex angle of the polygon corresponds to a peripheral electrode; by optimizing the electrode space layout through rotational symmetry layout and narrow strip-shaped gap setting, an electric field superposition effect is formed between the central electrode and the peripheral electrodes, and a stronger electric field effect is generated in the central region. The electric field is evenly distributed in the direction of each vertex angle of the central electrode, achieving the uniformity and consistency of the electric field distribution. The narrow strip-shaped gap setting reduces the influence of the edge effect on the electric field in the central region.

[0029] According to the principle of electric field superposition, the charges collected by each electrode will generate their own electric fields, and these electric fields can be vectorially superimposed. In a layout where the central electrode adopts a polygonal design and each vertex angle or each side corresponds to a peripheral electrode, the electric fields formed between the central electrode and the peripheral electrodes will be complexly superimposed. Since the polarities of the central electrode and the peripheral electrodes are opposite, strong electric field lines will converge between the electrodes, especially at the vertices or edges of the central electrode, where the electric field intensity will increase significantly due to charge concentration.

[0030] The edge effect in the electric field will cause the electric field intensity to peak or trough at the edge. In the above solution, the gaps between adjacent two peripheral electrodes and the gaps between the peripheral electrodes and the central electrode are designed to be narrow strip-shaped, and the narrow strip-shaped gap setting can reduce the influence of the edge effect on the electric field in the central region, making the electric field in the central region more uniform and stable.

[0032] In the above solution, the end faces of the peripheral electrodes are L-shaped and have the same shape and size, forming a stable and uniform electric field distribution between the electrodes. The L-shaped end face design may increase the effective area of the electric field action, thereby improving the efficiency and uniformity of treatment. The exposed face of the central electrode is in the shape of a rectangle with rounded chamfers, and each vertex of the rectangle corresponds to a peripheral electrode. This layout helps to precisely control the action area of the electric field.

[0033] In one implementation, referring to Figures 1 to 3 , the electrode head assembly further includes: a light guide bracket 104, a first circuit board 105, and the housing 101, the light guide bracket 104, and the first circuit board 105 are arranged in sequence from the outside to the inside.

One electrode positioning hole is used to accommodate one central electrode 102 or one peripheral electrode 103, and the electrode positioning holes penetrate the housing in a direction perpendicular to the exposed face of the housing.

N electrode positioning holes are provided on the first end face of the light guide bracket, and the electrode positioning holes penetrate the light guide bracket, and each electrode positioning hole corresponds to one electrode.

[0036] In the above solution, the housing, the light guide bracket, and the first circuit board are arranged in sequence from the outside to the inside, realizing the compactness and integration of the structure, and improving the internal connection efficiency and stability of the components. Electrode positioning holes are provided on the housing, and each positioning hole is used to accommodate one central electrode or peripheral electrode, ensuring the accurate positioning and fixation of the electrodes. Through the design of the electrode positioning holes, the manufacturing and assembly processes of the electrode head assembly become simpler and more efficient. Each electrode can be accurately inserted into the corresponding positioning hole without complex adjustment and alignment, reducing the manufacturing cost and assembly difficulty.

[0042] In the above solution, a second light source is provided on the first surface of the first circuit board, and the LED lamp beads face the gap (i.e., the first narrow band region) between two adjacent peripheral electrodes. Since the LED lamp beads face the gap region with weak electric field effect, additional light is provided in the region with weak electric field effect, thereby enhancing the synergistic effect of the electric field and the light.
