Rotating the limit screw 17 can adjust the pressure value of the strong and weak box assembly 132 on the sensor 134 .

That is to say, the initial pressure value of the sensor can be adjusted by adjusting the limit screw, that is, the calibration of the initial value of the sensor can be completed by mechanical adjustment. The problem of inconsistency in the adjustment of each massage movement caused by the difference ensures the stability of the massage movement and can also realize the standardization of the massage movement.

Rotate the limit screw 17 to adjust the pressure value of the strong and weak box assembly 132 on the sensor. Specifically, the following operations can be performed.

Step S1: Detect the initial pressure value of the sensor.

Step S2: determine whether the initial pressure value belongs to the preset initial pressure value range, if not, rotate the limit screw to adjust the pressure value of the sensor to the preset initial pressure value range, so as to realize the initial pressure value of the sensor Calibration.

Wherein, the preset initial pressure value range may be determined according to the sensor model and an empirical value, which will not be repeated in this embodiment of the present invention.

Now that the sensor is set, of course, the massage intensity can be adjusted by detecting the sensor value. Specifically, the following operations can be performed.

According to the detected pressure value of the sensor, the strong and weak motors are adjusted to drive the strong and weak gears to rotate clockwise or counterclockwise, so that the meshing sector teeth drive the massage components to move closer to the user's back or away from the user's back.

Through this step, the pressure value of the sensor can be detected in real time, and then the fixed intensity of the massage component can be adjusted in real time, so that the real-time adjustment of the user's back massage intensity can be realized, and the user experience can be improved.
