When the air-pressure-limiting type piston is used specifically, the pressure relief hole is formed in the bottom of the air cavity 21, where the first spring 13 is arranged, so that the space where the counter weight block 19 is located, at the bottom of the piston 12 is always in a normal air pressure state, the position of the piston 12 can be limited through the arrangement of the fixing column and the roller, the piston 12 can slide more smoothly through the roller, in an initial state, the piston 12 and the counter weight block 19 are located at the bottom close to the air cavity 21, and the first spring 13 is in a normal state; when the barrel 2 rotates, the fixing plate 7 revolves around the central axis of the barrel 2, due to the centrifugal force and gravity, the counterweight block 19 moves towards the second connecting pipe 17, the piston 12 moves towards the second connecting pipe 17, the first spring 13 is stretched, when the piston 12 slides towards the second connecting pipe 17, the gas in the gas cavity 21 is compressed and enters the sealed gas bag 14 through the gas outlet valve 16, the conical spring of the gas inlet valve 15 is in an initial state, namely, the semicircular block is pushed to block the gas inlet, the pushing direction of the conical spring is consistent with the direction of air to be discharged, so that the gas inlet is completely blocked, and similarly, because the blocking direction of the gas outlet valve 16 is opposite to the gas discharging direction, the gas can extrude the circular block to move towards the second connecting pipe 17, so that the circular spring is stressed and compressed, the gas can enter the second connecting pipe 17 through the gas outlet valve 16, the gas can enter the sealed gas bag 14 through the sealing mechanism 18 and the communication mechanism, so that the gas can be filled and expanded, and thus, a groove corresponding to the side wall of the barrel 2 is provided, the barrel 2 is attached to the barrel cover 3, and the self-cleaning effect is improved; when the fixing ring 7 stops rotating along with the barrel 2, the reset tension of the first spring 13 can be matched with gravity to pull the counterweight block 19 back to the initial state, so that the piston 12 moves along with the counterweight block 19, and because a negative pressure state can occur in the air cavity 21 at the moment, the air outlet valve 16 can move towards the direction of the piston 12 to connect and block the second connecting pipe 17 and the air cavity 21, so that the air in the sealed air bag 14 cannot flow back, and the air inlet valve 15 in the air inlet can be flushed away by external air, so that the air enters the air cavity 21, when the air pressure in the air cavity 21 is normal, the air inlet valve 15 immediately blocks the air inlet, and further, the next rotation is ensured to inflate the sealed air bag 14;
after cleaning, a worker firstly unscrews the bolt 6, in the process, the second spring 184 in the sealing mechanism 18 resets to restore the upright rod 182 and the sealing sleeve 181 to the initial state, then the sealing sleeve 181 leaves the first connecting pipe 11 and the second connecting pipe 17, and the sealing performance between the first connecting pipe 11 and the second connecting pipe 17 is reduced, so that the gas in the sealing air bag 14 is discharged through the first connecting pipe 11 and the second connecting pipe 17 of the communication mechanism, the sealing performance between the barrel 2 and the barrel cover 3 is reduced, finally the barrel cover 3 can be taken down by sliding the limiting rod 5, and as the sealing air bag 14 is not in a filling state, in the process of detaching the barrel cover 3, the sealing air bag 14 is forced to shrink, so that the friction between the sealing air bag 14 and the barrel 2 is small, the abrasion of the sealing air bag 14 is reduced, and the service life of the sealing air bag is prolonged.
