[0062] Such as figure 2 As shown, the first control module 4 includes:
[0063] The first pressure relay YJ1 installed inside the car tire;
[0064] When the pressure value of the automobile tire is less than the first preset value, the first pressure relay YJ1 is closed, the first coil DV1 is charged, so that the reversing valve is in the first state, and the inflation device inflates the automobile tire ; When the pressure value of the automobile tire is greater than the second preset value, the first pressure relay YJ1 is disconnected, the first coil DV1 is de-energized, and under the action of the first return spring, the reversing valve returns to When it is in the second state, the inflation device stops inflating the automobile tires; wherein, the first preset value is less than or equal to the second preset value.
[0065] Specifically, a first pressure relay YJ1 is installed inside the tire of the car. When the tire pressure of the car is lower than the set pressur...
