Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
With reference to accompanying drawing, the present invention includes the solenoid valve 1 that has water inlet 3, water delivering orifice 2, power autonomous, leakage sensor 9 and control circuit 4, control circuit 4 pick out lead 5 and connect leakage sensor 9.Solenoid valve 1 is installed on the inlet channel of water purifier, and leakage sensor 9 is inlayed or is adhered to the position that water purifier body lowest part or water purifier are easy to catchment.Control circuit 4 comprises first relay, second relay and the time-delay mechanism 8 of topworks, the coil K1 of first relay connects a utmost point of leakage sensor 9, the coil K2 of second relay connects another utmost point of leakage sensor 9 by time-delay mechanism 8, the contact J1 of first relay connects a utmost point of solenoid valve 1, the contact J2 of second relay connects another utmost point of solenoid valve 1, and power autonomous, solenoid valve 1, leakage sensor 9 and topworks form two-cycle scheme.Time-delay mechanism 8 can adopt a time relay 10.Between the coil K2 of second relay and time-delay mechanism 8, be connected in series a reset switch 7, pilot lamp 6 of serial connection on the reset switch 7.
Under normal circumstances, anhydrous assembly between two probes of leakage sensor 9, leakage sensor 9 probes are in open-circuit condition, the control circuit no power, solenoid valve 1 often leaves, the water purifier work of normally intaking.
When water purifier leaks, institute leaks and assembles in leakage sensor 9 probe places, utilize the electric conductivity (the faint electric conductivity that comprises pure water) of water, leakage sensor 9 will sense the coil K1 connection of leaking signal and making first relay, the first corresponding simultaneously relay contact J1 adhesive, solenoid valve 1 is switched on closed, closes into water.Simultaneously because the coil K3 of the time relay gets electricly, and time corresponding relay contact J3 disconnects, and makes the automatic dead electricity of relay coil K1 of winning, the first relay contact J1 disconnects.Because solenoid valve 1 is a self-locking type, the self-retaining function of itself is kept closed solenoid valve 1 always.When solenoid valve 1 cut out, circuit disconnected immediately.
After water leakage fault is got rid of, manually press reset key 7, the coil K1 of first relay, the coil K2 of second relay connects simultaneously, the first corresponding relay contact J1, the second relay contact J2 moves simultaneously, the utmost point effect of leading by the second relay contact J2, make the circuit acting in opposition on solenoid valve 1, solenoid valve 1 is opened, and by self-retaining function own, solenoid valve is held open state always, simultaneously the coil K3 of the time relay also electric, the contact J3 of the time relay returns to closure state, returns to original state normally.
Power supply electric energy deixis: when pressing reset switch 7, pilot lamp 6 circuit are connected, and can judge whether to need to change power supply this moment by the brightness of pilot lamp 6.When pressing reset switch 7, pilot lamp 6 is bright, and expression power supply abundance can continue to use; When pressing reset switch 7, pilot lamp 6 brightness are not enough or do not work, and expression needs to change power-supply battery or charge the battery.When not pressing reset switch 7, pilot lamp 6 is in and extinguishes state.
Transistor D1, the main effect of D2 is the protective relay coil, transistor D3 mainly play the guiding role.
Battery is installed in the battery case, and battery case is provided with to be renovated.Open and renovate, can freely change battery.
This leak-proof device circuit part is each only need to provide power supply in short-term, and battery need not continued power, and is very energy-conservation.
