Technical field

The present invention relates to water purifier, particularly the leak-proof device of family expenses direct drinking type water purifier or pipeline water dispenser.

Background technology

Universal day by day along with household water filter driven the flourish of water purifier industry.But each producer, the particularly level of first accessory manufacturing firm are uneven, make the potential safety hazard of water purifier extensively exist, because of the accident of flooding user's household of leaking happens occasionally, seriously shaken the confidence of market to water purifier, become one of major reason of restriction water purifier industry development.The seepy question that solves water purifier is extremely urgent.

Application number is that 03258390 Chinese invention patent application discloses a kind of leak stop, is Purely mechanical, comprises box body, lid, it is characterized in that also comprising spring, Slide Box and compound paper tape; The box portion left right side central has the passage that can hold water hose, be higher than the passage place symmetric restraining plate is arranged, the bottom surface of box body has two wire casings, there is the spring support of cross section and spring coupling at two interior height places to passage of wire casing, have chute in the outer wall of spring support in the heart, there is the slideway wide with spring support at channel height to place, box top; Slide Box is for lacking bottom surface and a lateral four sides hollow body, and the nose gusset of band holding tank is arranged on the lateral plane of symmetry outer wall of sky, the cross section of Slide Box also with the spring coupling, and can in slideway and spring support, slide; It is ring-type that compound paper tape is engaged by clamp, and its size should satisfy holding tank and passage and tie by described wire casing cover when straight substantially spring is to a certain degree compressed on the Slide Box in the spring support into.The patent No. is that the Korean Patent of N00485001 discloses a kind of water purifier leak-proof device, also be to adopt mechanical structure, utilize paper tape do, different qualities by-pass valve control under the wet situation or the closure of the edge of a knife, cut off water inlet pipe, stop and leak the purpose that further takes place thereby reach when feeling water purifier and leak.The major part paper tape of above technical scheme is disposable products, and accessory can only be had a monopoly in, and use cost is higher, and changes trouble, brings suitable difficulty for its technology popularization.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of easy handling is provided, the water purifier leak-proof device that can use continuously.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

A kind of low-voltage electronic energy-saving anti-leaking device for water purifier, comprise and having into, the magnetic valve of water outlet, power autonomous, leakage sensor and pilot circuit, it is characterized in that: described magnetic valve is installed on the inlet channel of water purifier, leakage sensor is inlayed or is adhered to the position that water purifier body lowest part or water purifier are easy to catchment, described pilot circuit comprises first rly. of topworks, second rly. and time-delay device, the coil of first rly. connects a utmost point of leakage sensor, the coil of second rly. connects another utmost point of leakage sensor by time-delay device, the contact of first rly. connects a utmost point of magnetic valve, the contact of second rly. connects another utmost point of magnetic valve, and is power autonomous, magnetic valve, leakage sensor and topworks form two-cycle scheme.

For optimizing technique scheme, the measure that the present invention taked also comprises:

Described time-delay device is the time relay.

Be connected in series a reset switch between the coil of described second rly. and the time-delay device, pilot lamp of serial connection on the described reset switch.

Because the present invention has taked above-mentioned technical measures, it compared with prior art has following advantage:

1, simple in structure, component are few;

2, easy handling can use continuously, and use cost is very low;

3, reliable operation.

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 magnetic valve 1 that has water-in 3, water outlet 2, power autonomous, leakage sensor 9 and pilot circuit 4, pilot circuit 4 pick out lead 5 and connect leakage sensor 9.Magnetic 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.Pilot circuit 4 comprises first rly., second rly. and the time-delay device 8 of topworks, the coil K1 of first rly. connects a utmost point of leakage sensor 9, the coil K2 of second rly. connects another utmost point of leakage sensor 9 by time-delay device 8, the contact J1 of first rly. connects a utmost point of magnetic valve 1, the contact J2 of second rly. connects another utmost point of magnetic valve 1, and power autonomous, magnetic valve 1, leakage sensor 9 and topworks form two-cycle scheme.Time-delay device 8 can adopt a time relay 10.Between the coil K2 of second rly. and time-delay device 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 pilot circuit no power, magnetic 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 electroconductibility (the faint electroconductibility that comprises pure water) of water, leakage sensor 9 will sense the coil K1 connection of leaking signal and making first rly., the first corresponding simultaneously relay1 contact J1 adhesive, magnetic valve 1 is switched on closed, closes into water.Simultaneously because the coil K3 of the time relay gets electricly, and time corresponding relay1 contact J3 disconnects, and makes the automatic dead electricity of relay1 coil K1 of winning, the first relay1 contact J1 disconnects.Because magnetic valve 1 is a self-locking type, the self-retaining function of itself is kept closed magnetic valve 1 always.When magnetic 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 rly., the coil K2 of second rly. connects simultaneously, the first corresponding relay1 contact J1, the second relay1 contact J2 moves simultaneously, the utmost point effect of leading by the second relay1 contact J2, make the circuit acting in opposition on magnetic valve 1, magnetic valve 1 is opened, and by self-retaining function own, magnetic 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 jar, and battery jar 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.
