In addition, the drive circuit includes a sequence control means for suspending water supply that exceeds a predetermined time that can be adjusted and maintains the floating state, and a second switch means for canceling the suspension of water supply.
．． With the power of fear, you can make clear that water will come out due to a misoperation (including mischief) or one malfunction.

Alternatively, the electric ERtf is equipped with a latching means and 7i
By setting the required power supply voltage for the opening operation of the i1i4i valve to a predetermined value (A) higher than the required power supply voltage for the closing operation, the power supply voltage will drop due to battery consumption and it will be impossible to open the valve. However, the closing operation is possible, and the first problem of water leaking out can be prevented.

[Example 1] Hereinafter, the present invention will be described based on an example with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention.

A drive circuit 2 connected to a power source 1 consisting of a battery and integrated with the power source 1 is built into the main body 4 of the water faucet 3,
Construct integrally.

Furthermore, the main body 4 is provided with an electromagnetic valve 5 connected to the drive circuit 2 through a conductive wire 5a to open and close the water supply faucet 3 to control the flow of water.

A switch means 7 connected to the drive circuit 2 by a conductor 12 and outputting a signal for opening and opening the solenoid valve 5 to the drive circuit 2 is provided near the water outlet 6 of the water faucet 3.

Furthermore, the drive circuit 2 includes a sequencer or control circuit (not shown) that stops the water supply exceeding a predetermined time using a timer and maintains the floating stone state, and a second switch means (not shown) that cancels the water supply stoppage. In order to avoid mischief, it is desirable to place the drive circuit in a place where it is not visible to other people near the drive circuit 2). Note that the predetermined time can be adjusted.

Switch/Sochi means 7 is infrared sensor, manual switch.

It consists of Chi et al.

Although the main body 4 has the Kiba adjustment device 8, it is not necessary to provide it.

In the state shown in FIG. 1, the valve body 10
is in a closed state, and water does not flow through the water pipe 11.

The state shown in FIG. 2 is the switch means 7 consisting of an infrared sensor.
detects the human hand 13, the electric Ell valve 5 operates, and the valve seat 9
The valve body 10 is in an open state.

For this reason, water flows through the water pipe II and flows out from the water outlet 6. For example, even if water is released due to mischief (sticking gum or the like to the front of the switch means 7) or malfunction, the timer After a predetermined period of time has elapsed, the water supply is stopped by the sequence control circuit. On this day, 1j2 treatment is performed using the switch means of the rear cylinder 2, which has eliminated the cause of the failure.

Although not shown in the figure, if a solenoid valve equipped with latching means is used and the required power supply voltage when the solenoid valve closes is set to a predetermined value larger than the required power supply voltage when the solenoid valve closes, the battery Even if the power supply voltage decreases due to wear and tear, and it becomes impossible to open the valve, it will still be possible to close the valve, and accidents such as water leaking out can be prevented on the 1st floor.

FIG. 3(a) shows another embodiment of the present invention, in which the water outlet 6 of the water supply faucet 3 is separated from the body 4 of the water supply faucet 3 together with the switch means 7 via a water pipe 11 or a boss. The switch means 7 and the drive circuit 2 are connected by a conductive wire 12 passing through the inside of the water pipe 11 or the inside of the hose.

Further, the conductive wire 12 is connected to a spiral elastic body I! as shown in FIG. 3(b). i112 El) and two insulated conductive wires 1 covered with an insulating film 12c.
2b.

If the insulating cover 11!2+2c has elasticity, it is not necessary to provide the elastic wire 12a.

[Determined effect 1] As explained above, in the present invention, the power source is composed of a battery, and the battery and drive circuit are integrated with the water supply faucet, so there is no risk of electric leakage or electric shock, and the cost of electrical work is reduced. This has the advantage that the number of parts is reduced, maintenance is simple, and it is not regulated as an electrical work.

Furthermore, in the embodiment, when the water outlet and the switch means of the water supply faucet are both separated from the main body of the water supply faucet via the water pipe or hose, the spiral elastic wire is stretched once and then By inserting it into the water pipe or hose and then loosening it, the conductor can be easily fixed inside the water pipe or hose, reducing electrical work costs and simplifying maintenance.

Also, it should be possible to prevent accidents such as water leaking out due to incorrect operation (including mischief) or malfunction.
