Title:
FLOW SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/058649
Kind Code:
A1
Abstract:
A flow switch device comprises a valve body (10) provided with a normally opened water flow channel and a normally closed water flow channel in the axial direction. A switching device (50) is arranged in the downstream direction perpendicular to the water flow and comprises a valve seat (52) provided perpendicular to the flow direction and a switching shaft (54) capable of sliding in the valve seat back and forth. The switching shaft has a large end and a small end. The small end is connected to a button (56) and extends out of the valve body, and the large end is abutted against an elastic member (58) mounted in the valve seat. In normal state, the elastic force of the elastic member acting on the switching shaft maintains the switching shaft in a first position, and the large end of the switching shaft blocks off the water flow in the normally closed water flow channel. When the button is pressed, the switching shaft is moved to a second position, thus the normally closed water flow channel is opened, the flow from the normally closed water flow channel passes through the large end and the small end of the switching shaft, and the pressure difference of the water flow between the large end and the small end overcomes the elastic force of the elastic member to maintain the switching shaft in the second position for the convenience of use.
