The inconvenience that people cause for fear of cutting off the water; usually can build a water vat at home; not enough or when not having when the water in the water vat; people are water filling inside; because other reasons such as be busy with one's work is closed water tap after will forgetting fills with water; water has been expired and will have been overflowed like this; floorboards of wood is steeped the damage of rotting or causing wooden furniture, cause the waste of unnecessary loss and water resource, present water tap comprises valve body; spool and valve rod; spool is installed on the valve rod; during use, rotary valve rod makes valve body unimpeded, and current come out from the valve body delivery port by valve body; and when finishing using, need once more the reverse rotation valve rod that valve body is closed.

The utility model content

Technical problem to be solved in the utility model provides the automatic water filling device of closing automatically after automatic water filling of a kind of energy and the fills with water.

The technical scheme that its technical problem that solves the utility model adopts is: automatic water filling device, comprise water vat and water tap, water tap comprises valve body, spool, it is characterized in that, also comprises level detecting device, the solenoid actuated device, water tap also comprises electromagnet, and valve body, spool and electromagnet are formed normally closed one way valve, and level detecting device is connected with the solenoid actuated device, the solenoid actuated device is connected with electromagnet, and described spool is the irony sphere;

Further, described level detecting device comprises glass tube, ball float and water level switch, described ball float and diameter glass tube adapt, ball float can endwisely slip along the glass tube inwall in glass tube, glass tube is positioned at water vat inside, one end is near water vat upper opening place, and the other end is near the water vat bottom, and water level switch is arranged on the end of glass tube near water vat upper opening place;

Further again, described glass tube is perpendicular to the water vat bottom, near the water vat inwall;

Concrete, described solenoid actuated device comprises relay power, relay and electromagnet power supply, described water level switch one end is connected with relay power one end, the water level switch other end is connected with relay, the relay power other end is connected with relay, described electromagnet one end is connected with electromagnet power supply, and the electromagnet other end is connected with relay, and the electromagnet power supply other end is connected with relay.

The beneficial effects of the utility model are, utilize normally closed one way valve, solenoid actuated device and the level detecting device of water tap, the function that automatic water filling and water are closed after completely automatically in the time of can reaching water vat and run out, the conserve water resource has also been avoided owing to forgetting that closing water tap causes the water spill-over to go out to damage furniture, and can keep the water yield in the water vat.

Description of drawings

Longitudinal section schematic diagram when Fig. 2 closes for the automatic water filling device of embodiment;

Wherein 1 is electromagnet, and 2 is spool, and 3 is valve body, and 4 is ball float, and 5 is water level switch, and 6 is glass tube, and 7 is relay power, and 8 is relay, and 9 is electromagnet power supply, and 10 is water vat.

The specific embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

Water tap of the present utility model is formed normally closed one way valve with valve body 3, spool 2 and electromagnet 1, and utilize the solenoid actuated device to control the open and close of normally closed one way valve, utilize level detecting device to control the work of solenoid actuated device, the automatic water filling device that utilizes hydraulic pressure, spool 2 gravity and electromagnet 1 magnetic force to form automatic water filling and close automatically.

Embodiment

This routine level detecting device comprises glass tube 6, ball float 4 and water level switch 5, described ball float 4 adapts with glass tube 6 diameters, ball float 4 can endwisely slip along the glass tube inwall 6 li of glass tubes, it is inner and perpendicular to water vat 10 bottoms that glass tube 6 is positioned at water vat 10, one end is near water vat 10 upper opening places, the other end is near water vat 10 bottoms, and glass tube 6 is whole near water vat 10 inwalls, water level switch 5 is arranged on the end of glass tube 6 near water vat 10 upper opening places, the solenoid actuated device comprises relay power 7, relay 8 and electromagnet power supply 9, described water level switch 5 one ends are connected with relay power 7 one ends, water level switch 5 other ends are connected with relay 8, relay power 7 other ends are connected with relay 8, described electromagnet 1 one ends are connected with electromagnet power supply 9, electromagnet 1 other end is connected with relay 8, electromagnet power supply 9 other ends are connected with relay 8, spool 2 is the irony sphere, longitudinal section schematic diagram such as Fig. 1 during this automatic water filling device water filling, longitudinal section schematic diagram such as Fig. 2 when closing.

When water vat 10 water fillings, water level switch 5 is in closure state, relay power 7 is connected relay 8 work that make, connect electromagnet power supply 9 and electromagnet 1, electromagnet 1 produces magnetic force irony spool 2 is held, open normally closed one way valve, water is flowed out, finish automatic water-filling function, and ball float 4 rises along with water level and rises along glass tube 6 inwalls, when water is filled with, ball float 4 arrives water level switch 5 positions, utilize buoyancy to back down water level switch 5, water level switch 5 is disconnected, relay power 7 disconnections this moment, relay 8 quits work and disconnects being connected between electromagnet 1 and the electromagnet power supply 9, electromagnet 1 no longer has magnetic force, and then the gravity owing to hydraulic pressure and spool 2 makes spool 2 stop up valve body 3 automatically, finishes and closes water tap automatically, when the water of 10 li of water vats is not enough once more, because drawdown, then ball float 4 no longer backs down water level switch 5 also with drawdown, make water level switch 5 closed again, this moment, relay power 7 was closed again, and relay 8 work make electromagnet power supply 9 be communicated with power supply with electromagnet 1 again, made electromagnet 1 work, produce magnetic force, hold the spool 2 of irony sphere, make normally closed one way valve unimpeded, restart water filling.And because glass tube 6 near water vat 10 inwalls, does not influence the water that uses 10 li of water vats.

Adding relay 8 in the solenoid actuated device of present embodiment and use relay power 7 and electromagnet power supply 9 to be respectively may be bigger because drive the magnitude of current of this electromagnet 1, and water level switch 5 is owing to the relatively more close water surface when water is filled with, might be stained with water because of a variety of causes and cause electric current instability, therefore not have directly to use water level switch 5 to go to control the energising and the outage of electromagnet 1 by water level switch 5.
