Description
Technical field
The utility model is specifically related to a kind of water flow switch.
Background technology
At present, water flow switch be control for the water circulation of electric heater, solar water heater, air conditioner and other water systems, Inlet and outlet water control, water computer heating control, pump switch control, electromagnetically operated valve break-make controls or the process such as water outlet power-off, water outlet energising control, current are converted to the senser element of the switching regulator signal of telecommunication after reaching certain flow.The structural design of existing water flow switch is unreasonable, thus this water flow switch exists the defect of unstable properties, complex structure, poor sealing performance.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provide that a kind of structure is simple, stable performance, good seal performance water flow switch.
For achieving the above object, the utility model adopts a kind of water flow switch, comprise box body, magnetic control means, described box body comprises base, be arranged on the upper cover on base, a containing cavity is configured with between described upper cover and base, described magnetic control means comprises control module, swing arm, be arranged on the magnet in swing arm, described control module is arranged in containing cavity, described control module comprises and is fixed on base interior circuit board, relay, fuse, capacitor, be arranged on the tongue tube on the lower surface of circuit board, described relay, fuse, capacitor is separately positioned on circuit board upper surface, the lower end of described tongue tube is arranged in the deep-slotted chip breaker in base, polyurethane rubber is filled with in described base, this polyurethane rubber is by circuit board, tongue tube is sealed in base, on the lower surface of described base, corresponding tongue tube place is provided with a cell body, one end of described swing arm is hinged in cell body.
The beneficial effects of the utility model are: this water flow switch adopts polyurethane rubber to be sealed in box body by circuit board, tongue tube, thus improve the water resistance of this water flow switch, thus this water flow switch has that structure is simple, stable performance, good seal performance advantage.This water flow switch operationally, water impact swing arm, swing arm inside is provided with magnet, current drive swinging arm, and when the tongue tube of swing arm on circuit board, tongue tube is by magnetic field induction conducting, board vias, the relay work on circuit board, thus control pump working.
