The elastic plate avoids the problem of winding and accumulation when the hose moves. At the same time, the telescopic rod and the contraction rod make the machine move more stably when working.

[0016] When the chlorine enters the inside of the chlorine barrel, the high-pressure pump increases the air pressure, so that the blocking plate moves on the surface of the sliding rod, so that the chlorine can enter the inside of the water inlet pipe. The spring makes the position more stable when moving and resets in time. The shock absorber has a damping effect, avoiding damage to the chlorine barrel caused by long-time work. The limiting rod limits the blocking plate. When the high-pressure pump is turned off, the blocking plate contacts the sealing sleeve to play a sealing role, avoiding the problem of backflow.
