In one embodiment of the present utility model, as shown in fig. 1, the first valve body 32 is a pressure release valve, the pressure release valve includes a valve body 323, a blocking portion 328 and an elastic member 329, a first air passage 324a and a second air passage 324b are formed in the valve body 323, the first air passage 324a is communicated with the air bag 2, two ends of the second air passage 324b are respectively provided with a first air passage 325 and a second air passage 326, the first air passage 325 is communicated with the air source 31, the second air passage 326 is communicated with the air, a gate 327 is disposed between the first air passage 325 and the second air passage 326 in the second air passage 324b, the blocking portion 328 is movably disposed at the gate 327 and is opposite to the second air passage 326, the blocking portion 328 has an initial position for sealing and blocking the gate 327 and an open position for opening the gate 327, one end of the elastic member 329 is connected with the blocking portion 328, and the other end of the elastic member 329 is abutted against or connected with one end of the valve body provided with the second air passage 326.

In this technical solution, as shown in fig. 3, the valve body 323 includes a first interface 320 and a third interface 322 that are horizontally extending and a second interface 321 that is vertically extending, the first gas passing channel 324a is located in the second interface 321, the second gas passing channel 324b penetrates through the first interface 320 and the second interface 321, two ends of the second gas passing channel 324b are a first gas passing port 325 and a second gas passing port 326, the first gas passing port 325 is communicated with the air source 31, the second gas passing port 326 is communicated with the air, a gate 327 is disposed between the first gas passing port 325 and the second gas passing port 326 in the second gas passing channel 324b, and the blocking portion 328 is movably disposed at the gate 327, so that the third interface 322 is an openable interface and serves as a pressure releasing end of the pressure releasing valve.

When the pressure release valve is in an initial state, the blocking portion 328 is in an initial position for blocking the gate 327, at this time, the blocking portion 328 closes the gate 327, and the gas outputted from the gas source 31 is inputted into the gas bag 2 through the first gas passing port 325 and the first gas passing passage 324 a. If the pressure of the gas output by the gas source 31 is too high, when the gas pressure of the second gas passing channel 324b is greater than the pressure release value of the pressure release valve, the gas entering from the first gas passing port 325 pushes the blocking portion 328 to move towards the direction close to the second gas passing port 326, so that the blocking portion 328 opens the gate 327, and the blocking portion 328 is switched to the pressure release position, and at the moment, the gate 327 is communicated with the second gas passing port 326, so that pressure release is realized, and the gas pressure output by the gas source 31 to the gas bag 2 is avoided. Along with the discharge of the gas in the second gas passing channel 324b, the pressure of the gas in the second gas passing channel 324b gradually decreases until the gas pressure in the second gas passing channel 324b is lower than the pressure release value of the pressure release valve, and then the blocking part 328 moves towards the gate 327, so that the blocking part returns to the initial position for closing the gate 327, and the third interface part 322 is in a closed state. It should be noted that the pressure relief value of the pressure relief valve should refer to the resistance value that the air flow in the second air passing channel 324b needs to overcome to push the blocking portion 328 rightward, that is, the resistance value corresponds to the preset pressure value.

Wherein the elastic member 329 is adapted to drive the blocking portion 328 to return from the pressure release position to the initial position.

Specifically, when the air pressure in the second air passage 324b is too high, the air flow in the second air passage 324b pushes the blocking portion 328 to the right by overcoming the resistance of the elastic member 329, so that the distance between the blocking portion 328 and the second air passage 326 is reduced, and the elastic member 329 is compressed to accumulate elasticity; until the blocking portion 328 opens the gate 327, the gate 327 communicates with the second gas passing port 326, and the leakage is achieved by communicating with the outside atmosphere. As the second air passage 324b leaks to the outside atmosphere, the air pressure in the second air passage 324b gradually decreases, and when the air pressure in the second air passage 324b is smaller than the elastic force accumulated in the elastic member 329, the elastic member 329 releases the elastic force accumulated therein and pushes the blocking portion 328 to the left, thereby blocking the gate 327 and restoring the blocking portion 328 to the initial position. The elastic force value of the elastic member 329 may be equal to the pressure release value of the pressure release valve. The greater the spring force of the spring 329, the greater the resistance that the air flow in the second air passage 324b needs to overcome to push the blocking portion 328 to the right, and the higher the air flow pressure in the second air passage 324b is required; conversely, the smaller. The pressure of the air bag 2 can be regulated and controlled by the corresponding design according to the highest value of the air pressure in the air bag 2, so that the air bag 2 has enough pressure and can avoid cracking caused by over high air pressure.
