The valve box 602 is provided with one-way check valves through which water advances, that is, passes at appropriate points on the bottom surface and side surfaces thereof. In the present embodiment, the one-way check valve is provided at each of a plurality of positions on the bottom surface and the side surface of the valve box 602. Specifically, the first one-way check valve that can only flow into the bottom surface of the valve box 602 is provided. A directional check valve I, a second one-way check valve II that can only flow out, and a through hole V are provided, and a third one-way check valve that can only flow in is provided on the side surface of the valve box 602. III and a fourth one-way check valve IV capable of only outflow are provided.

It is worth mentioning here that the present invention separately manufactures the cylindrical body 601 and the valve box 602 in order to improve the watertight effect and the convenience of production, and then the high frequency or adhesive is used. The two are bonded by the agent as shown in FIG. Of course, if the molding technology is further advanced, it may be manufactured by the integral molding method. As shown in FIG. 4, the upper end of the valve box 602 is externally fitted to the lower end of the cylindrical body 601 to join the two. At this time, the lower end of the cylindrical body 601 is the third and fourth parts of the valve box 602. The one-way check valves III and IV are joined so as to be located above them.

The adjusting cylinder 50 has a cylindrical cup shape and has an inner diameter slightly larger than the outer diameter of the valve box 602 so that the valve box 602 can be fitted therein. 02 One bottom hole 51 is formed at a position corresponding to the one-way check valves I and II on the bottom surface, and the one-way check valve III on the side surface of the valve box 602 is provided on the cylindrical wall near the bottom plate. , IV, one wall hole 52 is provided at the level position, that is, the height, and a male screw 53 is threaded on the surface of the protruding ring portion provided on the upper end side of the cylinder wall.

The bottom hole 51 and the wall hole 52 of the valve 50 are made to correspond exactly to the first one-way check valve I and the fourth one-way check valve IV of the valve box 602, and the funnel 80 is fitted and fitted to the funnel. When the relatively small second opening 82 of 80 is inserted into the water and the handle 611 is raised by hand by hand, the piston plate 62 also moves upward at the same time to form an upward water absorption force, and the water becomes the second It is sucked into the valve box 602 from the opening 82 through the bottom hole 51 through the corresponding first one-way check valve I. Then, when the handle 611 is pushed downward by hand, the piston plate 62 is also moved downward at the same time to form downward pressure, so that the water sucked into the valve box 602 corresponds to the corresponding wall hole 52. 4 will be discharged via the one-way check valve IV, forming one pump device.

Next, as shown in FIG. 3, when the present invention is used for general drainage, the pump 60 and the adjusting cylinder 50 are appropriately rotated relative to each other so that the bottom hole 51 and the wall hole of the adjusting cylinder 50 can be changed. When 52 is made to correspond to the second one-way check valve II and the third one-way check valve III of the valve box 602, respectively, and the handle 611 is raised by hand, the water flows in the third one-way check valve. If the handle 611 is pushed down by hand after flowing into the pump 60 through the check valve III, the water in the pump 60 is discharged through the second one-way check valve II.

When the through hole V and the bottom hole 51 of the adjusting cylinder 50 are simply made to correspond to each other, the wall hole 52 is closed, so that the through hole V facilitates simple water absorption or drainage operation. Can be made.
