[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] like Figure 1 , Figure 2 As shown, a first embodiment of a switch structure of a razor cleaning base provided by the utility model is shown. In this embodiment, it includes a razor handle 1 and a cleaning base 2. The placement position of the cleaning base 2 matches the shape of the top of the razor handle 1. The razor handle 1 is provided with a first magnetic contact 11, and the cleaning base 2 is provided with a second magnetic contact 21. The second magnetic contact 21 is located at a position opposite to the first magnetic contact 11 when the razor handle 1 is placed on the cleaning base 2. The first magnetic contact 11 and the second magnetic contact 21 are pressing magnetic contacts. The magnetic poles of the first magnetic contact 11 and the second magnetic contact 21 are opposite. The first magnetic contact 11 and the second magnetic contact 21 are electrically connected after being connected, so that the razor handle 1 can supply power to the cleaning base 2.

[0032] like Figure 3 , Figure 4As shown, in the above technical solution, the first magnetic contact 11 includes a pressing contact 111, a connecting spring 112, a connecting contact 113 and an electric control board 114. The pressing contact 111 has two cylindrical ends, one end of which is exposed on the outside of the housing of the razor handle 1, and the other end contacts the connecting spring 112 when the razor handle 1 is placed on the cleaning base 2. The connecting spring 112 has two L-shaped ends, the side walls of which are in contact with the pressing contact 111, and the bottom end is detachably fixed to the outer shell of the razor handle 1. Internally, a second contact extends from the bottom end of the connecting spring 112 for electrically connecting to the electric control board 114. The extended end of the connecting spring 112 is adjacent to the side wall of the connecting spring 112. There are two connecting contacts 113, each of which is cylindrical. The top of the connecting contact 113 contacts the extended section of the connecting spring 112, and the bottom is fixedly connected to the electric control board 114. The electric control board 114 is annular and is fixed inside the razor handle 1 for supplying power to the razor handle 1 and the cleaning base 2.

[0033] Furthermore, in the above technical solution, a recess is provided at the position where the side wall end of the connecting spring 112 contacts the pressing contact 111 .

[0034] Furthermore, in the above technical solution, the cross section of the depression is arc-shaped.

[0035] Furthermore, in the above technical solution, the connecting spring piece 112 is fixed inside the razor handle 1 by being detachably mounted on the cylindrical protrusion of the motor frame cover assembly inside the razor handle 1 .

[0036] Furthermore, in the above technical solution, the line connecting two adjacent pressing contacts 111 is parallel to the electric control board 114 .

[0037] Furthermore, in the above technical solution, the end of the pressing contact 111 that contacts the connecting spring 112 is hemispherical.

[0038] Specifically, the principle of the present utility model is:

[0039] 1. Working Principle of Magnetic Contacts: Magnetic poles attract: The first magnetic contact on the razor handle and the second magnetic contact on the cleaning base have opposite magnetic poles. Therefore, when the razor handle is placed on the cleaning base, the two magnetic contacts automatically fit tightly together due to magnetic attraction.

[0040] Electrical connection: When the magnetic contacts are in close contact, an electrical connection is established between the first and second magnetic contacts. This electrical connection enables the shaver handle to provide power to the cleaning base, thereby activating functions such as cleaning or charging within the cleaning base.

[0041] 2. Working Principle of the Internal Circuit Structure: The internal structure of the first magnetic contact consists of a pressure contact, a connecting spring, a connecting contact, and an electronic control board. The pressure contact is exposed on the outside of the shaver handle housing and is used to contact the second magnetic contact on the cleaning base. The connecting spring is L-shaped, with its sidewall in contact with the pressure contact. When the shaver handle is placed on the cleaning base, it deforms under the pressure of the pressure contact, forming a close contact with the connecting contact.

[0042] Electrical connection path: When the connecting spring is pressed and firmly contacts the connection point, current flows through the second contact of the connecting spring and enters the electronic control board. The electronic control board then distributes it to the corresponding circuits of the shaver handle and the cleaning base. In this way, the shaver handle not only supplies power to the cleaning base, but also manages the entire circuit and power distribution through the electronic control board.

[0043] 3. Principle of the Improved Design: Concave and Arc-Shaped Cross-Section: A concave section is formed where the sidewall of the connecting spring contacts the pressing contact. This concave section is arc-shaped. This design reduces wear on the contact surface, improves durability, and ensures good electrical contact.

[0044] Removable fixing: The connecting spring is removably fixed to the inside of the shaver handle through the cylindrical protrusion of the motor frame cover assembly inside the shaver handle. This design facilitates installation and maintenance, and also improves the flexibility of the structure;

[0045] Parallel layout: The connection line of two adjacent pressing contacts is parallel to the electronic control board. This layout is not only beautiful, but also helps to reduce interference between circuits and improve circuit stability.

[0046] Hemispherical contact end: The end of the pressing contact that contacts the connecting spring is hemispherical. This design increases the contact area and further improves the stability and reliability of the connection.

[0047] In summary, the switch structure of the razor cleaning base of the utility model realizes convenient, stable and reliable power transmission and circuit control between the razor handle and the cleaning base through the mutual attraction and electrical connection of the magnetic contacts and the ingenious design of the internal circuit structure.

[0048] During use, the first magnetic contact 11 on the razor handle 1 is squeezed, the pressing contact 111 moves inward, and contacts the connecting spring 112. The extended end of the connecting spring 112 contacts the connecting contact 113, and the other end of the connecting contact 113 contacts the electric control board 114, so that the pressing contact 111 contacts the electric control board 114, the pressing contact 111 is energized, the first magnetic contact 11 contacts the second magnetic contact 21, and the razor handle 1 supplies power to the cleaning base 2.
