Abstract: The present disclosure discloses a multi-electrode miniature electrical stimulation system, including a BOOST circuit and a voltage doubling circuit; the core of the BOOST circuit is a switching power chip; a stimulation waveform control circuit includes several half-bridge drive circuits; each half-bridge drive circuit is correspondingly connected with one electrode, and any half-bridge drive circuit can output a bidirectional stimulation current; a voltage-controlled constant current source circuit includes an operational amplifier, a multi-channel analog switch and several diffusing power tubes; the operational amplifier works in a negative feedback working state.

Abstract: The present disclosure discloses a wristband nerve stimulator applicable to both the left and right hands and a use method thereof. The wristband nerve stimulator includes a fixed main unit and an electrode piece band; a groove and an adapter port are respectively arranged on two sides of a bottom of the fixed main unit; a controller is arranged in the fixed main unit; the controller includes a main control unit (MCU), an intelligent identification unit, a storage unit and a stimulation unit; the electrode piece band comprises a base and an electrode assembly; adapter seats are arranged on two sides of a top surface of the base; a memory IC is arranged in the base; the memory IC is provided with an independent identification ID and can record the number of use or the service life of the electrode piece band.

Abstract: The present disclosure discloses a fixing structure of two watchbands, including a main unit, an inner band and an outer band, wherein the inner band is connected with a bottom of the main unit; the outer band is rotatably connected with one side of the main unit; a groove is arranged on an outer side of the inner band; a hook surface is arranged in the groove; a loop surface matched with the hook surface is arranged on an inner side of the outer band; and the hook surface is adhered to the loop surface. In the present disclosure, by the arrangement of the hook surface and the loop surface, the hook surface and the loop surface are adhered, so that the inner band and the outer band can overlap each other to be fixed, which avoids the inner band from shifting to affect the use effect.

Abstract: The present disclosure discloses a waterproof button structure, including a button main body, a shell and a shaft sleeve, wherein a button mounting slot is reserved on the shell; a vertical column is arranged in the button mounting slot; the vertical column is provided with a through hole longitudinally penetrating through the vertical column; the button main body includes a pressing portion and a shaft portion; a bottom surface of the pressing portion is provided with a first annular groove; a second annular groove is formed between the vertical column and an inner wall of the button mounting slot.

Abstract: The present disclosure discloses a manufacturing method of a wristband embedded with multiple groups of electrode pieces. The present disclosure provides a band manufacturing method that can take metal electrodes and silica gel electrodes into account, which ensures that the electrodes are firm and will not fall off when the wristband is worn. All the electrodes are clung to the skin through electrode bands, so that the wires are effectively prevented from being intertwined and broken, and the service life of the wires can be prolonged. Meanwhile, fast mounting and connection between the electrodes and the main unit are realized, and it can also be ensured that joints of the band and the main unit after assembling are waterproof.
