Description

Technical Field

[0001] The utility model relates to the field of instruments, in particular to an antipruritic instrument. Background Art

[0002] An antipruritic device is an electronic device used to relieve itchy skin. It usually uses a technology called electrical itch stimulation to stimulate the skin by providing weak current or vibration to reduce or prevent itching. When using an antipruritic device, it is placed on the itchy area, and then it stimulates the nerve endings through low-intensity current or vibration and affects nerve transmission, thereby reducing or eliminating the itching sensation. This stimulation is believed to interfere with the transmission of skin nerve signals and reduce the brain's perception of itching.

[0003] The anti-itching instrument is powered by a battery, and a battery positive electrode sheet and a battery negative electrode sheet are provided in the anti-itching instrument. The positive electrode of the battery abuts against the positive electrode sheet of the battery, and the negative electrode of the battery abuts against the negative electrode sheet of the battery to power the anti-itching instrument. The positive electrode sheet and the negative electrode sheet of the battery in the existing anti-itching instrument are welded to the control circuit board through a power line, resulting in inconvenient connection operation between the existing battery positive electrode sheet, the battery negative electrode sheet and the control circuit board, low production efficiency, and waste of labor and material costs. Utility Model Content

[0004] The utility model solves the problems of low connection efficiency between the battery negative electrode sheet and the control circuit board of the existing antipruritic instrument, and waste of labor and material costs.

[0005] The technical solution adopted by the utility model is an anti-itching instrument, comprising a shell, the shell comprising an upper shell and a lower shell, an installation cavity is formed between the upper shell and the lower shell, a control circuit board and a battery are arranged in the installation cavity, a battery negative electrode sheet is arranged in the control circuit board, the other end of the battery negative electrode sheet is inserted into the lower shell, a battery positive electrode sheet is arranged at one end of the lower shell away from the battery negative electrode sheet, the battery positive electrode sheet is electrically connected to the control circuit board through a power line, the negative electrode of the battery abuts against the negative electrode sheet of the battery, and the positive electrode of the battery abuts against the positive electrode sheet of the battery.

[0006] The beneficial effects of the utility model compared with the prior art are as follows: the control circuit board is plug-connected with the negative electrode sheet of the battery, making the connection between them more convenient and quick, saving labor and material costs, and improving the production efficiency.
