Title:
POSITIVE AND NEGATIVE INSERTION SWITCHING CIRCUIT AND SYSTEM, AND SMART WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/196782
Kind Code:
A1
Abstract:
A positive and negative insertion switching circuit and system, and a smart wearable device. The circuit comprises an input port (10), an on-off state switching module (20), and an output port (30); the on-off state switching module (20) is connected between the input port (10) and the output port (30); the input port (10) is used for connecting a charging power supply; the on-off state switching module (20) is used for switching the flow direction of the current of the connected power supply to satisfy the positive and negative electrode directions of the output port (30), so as to supply power for the smart wearable device. The present invention can reduce the size of the smart wearable device, and achieve positive and negative insertion charging while reducing the risk of a short circuit occurring to a suction head and the risk of electro corrosion.
