Abstract:
The invention discloses a fluid sensing device provided in a flow path through which fluid flows, including a base fixed in the flow path; a piston core rod disposed in the base and connected to the base through an elastic member, the piston core rod being provided with a pushing surface pushed by the fluid in the flow path; a magnet provided on the piston core rod; a magnetic sensing device provided on a side surface of the piston core rod to sense change of magnetic line received as change of position of the magnet, thereby determining whether fluid flows in flow path; wherein the elastic member is disposed such that direction of the restoring force thereof is opposite to the direction of fluid flow in flow path. The present invention has fewer parts and easy production, and can reduce judgement difference caused by low flow rate.

Claim (Index 16):
The fluid sensing device according to  claim 7 , wherein the third part is composed of two rod bodies, a middle part of one of the two rod bodies protrudes with a cylinder-shaped connecting part, a middle part of the other of the two rod bodies concaves with a circular hole channel, the connecting part is inserted in the circular hole channel, the connecting part and the inner wall of the circular hole channel formed on the piston core rod are in a threaded connection; and\n the fluid sensing device further comprises: a vertical rod fixed on the side wall of the fourth part and parallel to the axis of the fourth part, the vertical rod capable of passing through the second through hole when the notch is tightened; and a support rod which is arranged in the downstream end of the pipe body along the flow direction of the fluid in the pipe body and fixedly connected with the inner side wall of the pipe body, the support rod being provided with a third through hole, the vertical rod passing through the third through hole, the first opening being entirely located in the base when the fourth part is laid on the support rod.
