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 15):
The fluid sensing device according to  claim 8 , wherein specific manner that the base is fixed on the pipe body is as follows:\n the pipe body and the base are both in an internally hollow cylindrical shape and arranged coaxially, a gap is arranged between the outer side wall of the base and the inner side wall of the pipe body, a plurality of supporting blocks is alternately arranged on the inner side wall of the pipe body along the circumferential direction, the bottom surface of the base provided with the second through hole is laid on a plurality of supporting blocks, the plurality of supporting blocks does not seal the third opening, the inner side wall of the pipe body and the outer side wall of the base being alternately provided with a plurality of connecting rods in the circumferential direction of the base, one end of each of the connecting rods is fixedly connected with the inner side of the pipe body, and the other end abutting against the outer side wall of the base.
