Massage device control circuit

Abstract

The invention discloses a massage device control circuit. The massage device control circuit comprises a power supply circuit, a microprocessor module connected with the power supply circuit, a driving circuit connected with the power supply circuit and the microprocessor module and a function selection circuit connected with the microprocessor module. The driving circuit comprises a motor forwardcircuit and a motor reverse circuit, wherein the motor forward circuit is formed by the first output pin of the routing microprocessor module sequentially connecting with a first transistor, a firstfield effect tube, a first motor, a second field effect tube and a grounding end, the motor reverse circuit is formed by a second output pin of the microprocessor module sequentially connecting a second transistor, a third field effect tube, a first motor, a fourth field effect tube and a grounding terminal, wherein the gate electrodes of the first, second, third and fourth field effect tubes arerespectively connected with the power supply circuit through a resistor. The massage device control circuit adopts the field effect tube to replace the relay to control the operation of the motor, saves the cost, and makes the circuit wiring simple and the volume is reduced.

Description

technical field [0001] The invention relates to a massager, in particular to a control circuit of the massager. Background technique [0002] Regarding massage, it is aimed at applying external force on the surface of the human body in order to eliminate muscle soreness and fatigue, and achieve the goal of relaxation and comfort. It is one of the ancient human health therapies; massage can be achieved by various methods or tools, such as compression, Stretching, kneading, thumping, hot and cold compresses, etc., to activate muscles and bones, promote blood circulation and metabolism, and achieve the purpose of relieving fatigue and enjoying physical and mental pleasure. [0003] After the history of mankind entered the industrial age, mass-produced machinery and tools replaced traditional manpower, providing humans with a more convenient life. Among them, the massager is a tool that provides individuals with self-massage without the help of others. At present, various massa...
