Claims

[Scope of utility model registration request]

(1) The reciprocating movement of the diaphragm opens and closes the flow path to suck the object to be sucked into the valve chamber of the pump body, and forcefully transports the object sucked into the valve chamber to a desired position outside the pump body. A diaphragm pump device configured to do this, wherein a flat plate-shaped valve body is interposed in the flow path of the pump body, and the valve body is configured to close the flow path when pressure is applied. , wherein at least the flow path upstream of the valve-interposed part of the flow path is formed so as to forcefully feed the object to be sucked upstream when the valve body is blocking the flow path. □ Earphragm pump device.

(2) The upstream flow path is composed of two or more flow holes opened in parallel, and at least one of these flow holes is located at a position wider than the projected area of the valve body. The diaphragm pump device according to claim 1, characterized in that the diaphragm pump device is arranged so that it is always present in the diaphragm pump device.
