When the staff observes that the liquid inside the liquid collecting tank 31 is full through the observation window 32, the staff can manually hold the hand wheel of the valve 23 and rotate the hand wheel in the counterclockwise direction, so that the valve core of the valve 23 gradually closes, thereby cutting off the flow of liquid in the liquid outlet pipe 22. Then, the staff pulls the movable block 25 horizontally to both sides, and the displacement of the movable block 25 drives the connecting column 26 to also displace horizontally outward, and the displacement of the connecting column 26 causes the limiting spring 27 on the outer wall of the connecting column 26 to be compressed under force, and the limiting spring 27 gradually changes from the natural extension state to the contraction state, and at the same time, the displacement of the connecting column 26 drives the limiting block 28 to slide horizontally along the inner wall of the limiting groove 29 to the inside, until the limiting block 28 is completely retracted inside the limiting groove 29, at which time the locking restriction on the collecting pipe 30 is released, so that the liquid collecting tank 31 can be smoothly removed under the slight lifting operation of the staff, thereby achieving the effect of quickly disassembling the liquid collecting tank 31.
