Set upper side is equipped with telescopic hole, and telescopic rod is sliding combined in telescopic hole, and telescopic rod upper end is fixedly connected with water inlet pipe upper end inner wall,
Telescopic rod and telescopic outer sheath are equipped with resetting spring.
As further program of the utility model：The limited block is annular shape.
As further program of the utility model：The water inlet inside pipe wall is equipped with wearing layer.
As further program of the utility model：It is to be detachably connected between the outlet pipe and caching cylinder.
As further program of the utility model：The port is located inside caching cylinder.
As further program of the utility model：The floating packing and fixing seal pad are all rubber pad.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple and reasonable for structure, in device
During work, under the action of immersible pump, water is gushed along on water inlet pipe, and then piston plate is jacked up so that piston plate is along flexible
Set and telescopic rod upward sliding, so that piston plate is slided into above port, then current can enter caching cylinder along port
In, then along outlet pipe discharge, when dive under water air pump inoperative when, under the action of resetting spring, piston plate blocks water inlet pipe,
So as to which the water in water conduction hose be prevented to flow back, when next time in use, there is no need to again by water filling again in water conduction hose, from
And play energy saving effect, be also avoided that in water pipe remaining ponding flow back into immersible pump caused by immersible pump stator with turning
Unnecessary friction and the unnecessary abrasion of water wheels thrust collar bearing seat, increase service life between son.
