Description

  The present invention relates to a manual pump device capable of supplying water stored in a water receiving tank or a water supply tank in a disaster or emergency.

  Conventionally, a diaphragm pump is used as a manual pump in a simple water purifier used in a disaster or the like in which a power failure or water outage occurs. A simple water purifier is comprised from the pump part 1, the operation part 2, and the filter part 3, as shown to Fig.12 (a), (b). FIG. 12A is a cross-sectional view of the right half of the pump section, and FIG. 12B is a cross-sectional view taken along line XX of FIG. A diaphragm pump is used for the pump unit 1. The pump body 10, the reciprocating pump shaft 11, the diaphragm clamping unit 12, the diaphragm 13, the pump shaft 11, and the inner wall 14 that partitions the pump body 10, the pump shaft 11 includes two engaging pieces 15, a stand 16 for supporting the pump, and the like. The operation unit 2 includes a handle 17 for operating the pump, a handle shaft 18, a link rod 19 attached to the handle shaft 18, a drive pin 20 attached to the link rod 19 and engaged between the engagement pieces 15, It consists of a grip 21 and the like. Further, the suction port 22, the suction passage 23, the suction valve portion 24, the valve ball 25, the variable volume pump chamber 26 formed between the diaphragm 13 and the pump body 10, the discharge valve portion 27, the valve ball 28, A discharge port 29 is provided, a pleated filter paper filter 30 is connected to the discharge port 29, and a high performance filter housing 31 provided with an antibacterial activated carbon 32 and a hollow fiber membrane filter 33 housed therein is connected. Yes.

  In the conventional manual simple water purifier, by rotating the handle 17 with the grip portion 21, the link rod 19 is rotated together with the handle shaft 18, and the drive pin 20 attached to the link rod 19 is also rotated. Then, as shown in FIG. 12 (b), the drive pin 20 is engaged between the two engagement pieces 15 attached to the pump shaft 11, so that the engagement piece 15 according to the rotation of the drive pin 20. , The pump shaft 11 also reciprocates left and right. In the figure, the pump shaft 11 is at the left end, and when the handle 17 is further rotated, the pump shaft 11 moves to the right end. As the pump shaft 11 reciprocates, the diaphragm 13 responds and the left and right inner chambers of the pump chamber 26 separated by the diaphragm 13 are alternately expanded and contracted. In response to the expansion and contraction of the left and right inner chambers due to the reaction of the diaphragm 13, the left and right pump chambers 26 suck water from the suction port 22 and are sucked into the right pump chamber 26 through the suction passage 23, and the right by the reaction of the diaphragm 13. As the pump chamber 26 is reduced, the water in the right pump chamber 26 is fed from the discharge port 29 to the filter unit 3. The suction and discharge of water are alternately repeated in the left and right pump chambers 26 and water is sent to the filter unit 3 (see, for example, Patent Document 1).
