[0011] By adopting the above technical solution, the cover can be quickly locked and unlocked through the combination of the spring and the snap-in ball; when the cover is aligned with the constant pressure controller body, the snap-in ball automatically snaps into the snap-in hole under the elastic force of the spring to achieve quick locking; when it needs to be opened, just gently press the snap-in ball to make it withdraw from the snap-in hole, and it can be easily unlocked, which improves the convenience and efficiency of operation.
