Motor and air valve control circuit

Abstract

The invention provides a motor and air valve control circuit, which is used for a massage chair, and comprises a power supply module, a micro-control module, a motor control module, an air valve control module and an air pump control module, the power supply module is electrically connected with the micro-control module, the motor control module, the air valve control module and the air pump control module, and the air pump control module is electrically connected with the micro-control module. The micro-control module is electrically connected with the motor control module and used for controlling the motor control module to start, the air valve control circuit is used for controlling an air valve, and the air pump control module is used for controlling the air output of an air pump; when the micro-control module inputs a PWM signal, the positive and negative rotation control of the motor can be realized, the control of a backrest motor, a walking motor and a kneading motor of the massage chair is realized, and a series of massage manipulation control is realized through different program control. The system is good in automatic control effect, good in experience effect and wide in application range.

Description

technical field [0001] The invention relates to the technical field of massage chair control, in particular to a motor and an air valve control circuit. Background technique [0002] A massage chair is a device that uses mechanical rolling force and mechanical force extrusion to perform massage. For people who sit for a long time to work and study, massage can improve blood circulation, help improve back pain and prevent diseases, improve sleep quality, and relieve general fatigue. [0003] In the prior art, the actions performed by the massage chair are all controlled by internal data. The mechanical calf massage part has sliding guide rails and tension springs. After the user sits on it, the stretching length of the calf massage part depends on the force exerted by the user's feet on the calf massage part, resulting in poor comfort of the calf massage part. . There is also a part of the stretching movement of the calf massage part that is electrically controlled, but wh...
