However, the current explosion-proof air bag for the air dish is provided with an electromagnetic valve for controlling the opening and closing of the air outlet end, and the electromagnetic valve is influenced by the material of the electromagnetic valve, so that magnetic foreign matters possibly exist in the electromagnetic valve, and if the magnetic foreign matters are possibly mixed into the material after being input into the air dish along with the pressure gas, the magnetic foreign matters of the material are out of standard.
Referring to fig. 1, based on this, the embodiment of the present application further provides an explosion-proof air bag for an air dish, which includes an air storage bag 100, a valve assembly 200, an air control 300, an air supply 400, and an electromagnetic control valve 500.

In some embodiments, referring to fig. 3 and 4, in order to enable the pneumatic control 300 of the present application to control the valve body 220 to rotate relative to the first housing 210, the pneumatic control 300 may include a second housing 310 and a valve stem 320, wherein the second housing 310 further has an air passage therein, and the air passage is further connected to the air supply 400, the valve stem 320 is movably disposed in the air passage of the second housing 310, and the valve stem 320 is further connected to the valve body 220. Therefore, when the electromagnetic control valve 500 controls the pipeline between the air supply member 400 and the air passage to be in the passage, the compressed air in the air supply member 400 can be input into the air passage, so as to push the valve rod 320 to move, and further, the valve body 220 connected with the valve rod 320 can move, so that the purpose of changing the relative position relationship between the valve body 220 and the first housing 210 can be achieved, and further, the valve assembly 200 can be switched between the first state and the second state.
When the valve body 220 is rotatably disposed in the first housing 210, accordingly, the compressed gas in the gas supply member 400 enters the gas passage of the second housing 310 to drive the valve stem 320 to rotate, so that the valve body 220 connected to the valve stem 320 can rotate.
The air control 300 further includes a slider 330 and an elastic member 340, where the slider 330 is movably disposed in the air channel of the second housing 310, and the outer wall of the slider 330 is in sealing fit with the inner wall of the air channel, so that the slider 330 can divide the air channel into an outer cavity 311 and an inner cavity 312, and the outer cavity 311 and the inner cavity 312 are respectively located on opposite sides of the slider 330, so that as the slider 330 moves in the air channel, the space between the outer cavity 311 and the inner cavity 312 can be correspondingly increased or decreased. The air supply member 400 may specifically communicate with the outer cavity 311, so that the air supply member 400 may push the slider 330 to move toward the inner cavity 312 after compressed air is introduced into the outer cavity 311. The valve rod 320 is provided with an external tooth portion 321 which is arranged around the circumference of the valve rod 320, the external tooth portion 321 is provided with a tooth portion, the sliding block 330 is provided with a rack portion 331 which is matched with the external tooth portion 321, therefore, after the external tooth portion 321 is meshed with the rack portion 331, the sliding block 330 can drive the rack portion 331 to move after moving, so that the external tooth portion 321 meshed with the rack portion 331 can rotate, and finally, the valve rod 320 connected with the external tooth portion 321 can rotate, and the valve rod 320 can drive the valve body 220 to rotate.

When the slider 330 is required to move reversely, the air in the outer cavity 311 can be extracted by the air supply member 400, so that the pressure in the outer cavity 311 is reduced, and the slider 330 moves towards the outer cavity 311, so that the valve rod 320 matched with the slider 330 can rotate reversely, and the valve body 220 connected with the valve rod 320 can also rotate reversely. In addition, the air supply member 400 may be provided to communicate with both the outer side chamber 311 and the inner side chamber 312, such that the air supply member 400 may inject compressed air into the outer side chamber 311 and the inner side chamber 312, respectively, so that the slider 330 may move toward the inner side chamber 312 or the outer side chamber 311, and thus the valve stem 320 may be rotated in a forward and reverse direction.
