As an important tool for men's daily care, the functions and performance of razors are also constantly upgraded. In addition to the basic shaving function, people also hope that razors can provide a more comfortable and personalized experience.

[0003] A human body conductive switch-activated shaver (announcement number CN217454007U) applied for by the applicant on 2022-06-08 includes a shell, a support, a circuit board, a blade holder, a blade net and a blade assembly; the support is accommodated in the shell; the support is provided with a through hole; the circuit board is arranged in the shell; the circuit board is connected to an elastic pin, which is retractably inserted in the through hole and protrudes outward; the blade holder is installed on the support and presses against the elastic pin; the blade net is installed on the blade holder and connected to the elastic pin via the blade holder. At this time, the blade net, the blade holder, the elastic pin and the circuit board are in an electrically connected state. After the blade holder is connected to the shell through a threaded structure, the pin of the elastic pin can be retracted in the through hole of the support and press against the blade holder, thereby electrically connecting the blade holder to the circuit board.

[0033] See also Figure 1-15 As shown, the utility model relates to a shaver with a micro-current function and an anti-mis-touch start function, comprising a head cover assembly 1 and a body assembly 2, wherein the head cover assembly 1 can be disassembled and assembled with the body assembly 2 through a buckle. Since this disassembly and assembly structure has been adopted in existing shavers, it will not be described in detail here.

[0034] The head cover assembly 1 is provided with a first electrode 12 and a second electrode 13 for fitting the face. The two electrodes have opposite polarities and are made of conductive material. When the head cover assembly 1 is attached to the face, the face contacts both electrodes at the same time to trigger the shaver normally. The existing shaver is started by touching the knife net, and the knife holder connected to the knife net needs to be made of conductive material. The overall manufacturing cost is high, and the knife net and the knife holder are in contact connection, which makes it difficult to ensure stable and reliable electrical contact, and the practicality is not strong. Compared with the prior art, the utility model improves the technical solution by setting two contacts on the head cover assembly 1, that is, forming two contacts on the head cover assembly 1 through the first electrode 12 and the second electrode 13. The components of the first electrode 12 and the second electrode 13 adopt a reliable welding structure to ensure good electrical connection. Only by touching the two contacts at the same time can the shaver be started normally to avoid accidental triggering.

[0035] The top of the body assembly 2 is provided with a first conductive needle 28 and a second conductive needle 29, and the first conductive needle 28 and the second conductive needle 29 are connected to the positive and negative poles of the circuit board 25 in the body assembly 2. After the head cover assembly 1 is assembled with the body assembly 2 by snapping, the first electrode 12 and the second electrode 13 are respectively in contact with the first conductive needle 28 and the second conductive needle 29 for conduction.

[0036] When in use, the shaver is started by fitting the head cover assembly 1 to the face, and no additional pressing or toggling of the switch is required, which improves the service life and simplicity of the shaver to a certain extent. The new structure is simple and easy to install. In addition, when shaving, the first electrode 12 and the second electrode 13 simultaneously contact the skin to form a closed circuit, releasing microcurrent, which can stimulate the skin muscles, accelerate skin renewal and metabolism, increase skin elasticity, improve the symptoms of sagging or sagging, and achieve the purpose of beauty and skin care.

The second electrode 13 includes a negative electrode 131, a negative circuit board 132, and a second spring pin 133. The negative electrode 131 is welded on the negative circuit board 132, and a pair of second spring pins 133 are welded below the negative circuit board 132. The positive circuit board 122 and the negative circuit board 132 are supported by the head cover bracket 15, the positive electrode 121 and the negative electrode 131 are exposed from the avoidance hole 111 to the top surface of the head cover shell 11, and are higher than the top surface of the head cover shell 11, and the contact points of the first spring pin 123 and the second spring pin 133 are respectively exposed from the bottom of the slot 152, so that after the head cover assembly 1 and the body assembly 2 are assembled, the first spring pin 123 and the second spring pin 133 can be elastically contacted with the first conductive pin 28 and the second conductive pin 29. It should be noted that in the present invention, the first spring pin 123 and the second spring pin 133 are made of conductive material. When the first electrode 12 including the positive electrode 121 and the second electrode 13 including the negative electrode 131 touch the human skin at the same time, a closed circuit is formed, the shaver is started, and the skin is acted on by microcurrent; when any of the first electrode 12 including the positive electrode 121 and the second electrode 13 including the negative electrode 131 is separated from the human skin, the circuit will be disconnected and the shaver will stop working; in order to ensure that the first electrode 12 including the positive electrode 121 and the second electrode 13 including the negative electrode 131 can be continuously contacted by the human skin at the same time during use, the electrode contact area can be connected and extended by using a conductive material, such as Fig.12 As shown, a first extension block 124 and a second extension block 134 of conductive material are attached to the surface of the head cover shell 11, the first extension block 124 is connected to the first electrode 12, and the second extension block 134 is connected to the second electrode 13. In order to facilitate the shaver to touch the first electrode 12 and the second electrode 13 when shaving the face back and forth, the first extension block 124 and the second extension block 134 are symmetrically arranged on the surface of the head cover shell 11.
