The present invention relates to an automatic supply and shut-off device of water used to be inserted into a faucet, to provide convenience in use and saving of water.

In general, the structure used to be fitted to the faucet has been used in recent years water regulators for controlling the direct water and the injection of water. However, the water control device is a control device for controlling the water directly and spraying when the water valve is open. For example, when washing dishes in the kitchen, the water splashing to the outside has been solved by controlling the spraying, but the water saving effect They also had to open and close the water valves one by one.

The present invention is to provide a device of a completely different configuration than the conventional configuration, first: the water is automatically supplied by touching the outer periphery of the device once by hand, the water is blocked when touched again when the use is complete Secondly, the water supplied by the driving of the motor by touch can be freely adjusted by direct and spray water. Third: When washing the hand, the water is automatically controlled by the hand sensor when the hand approaches a certain distance. It is supplied to automatically shut off the water when evacuation of the hand, intended to achieve the convenience of use and saving water.

Looking at the configuration of the present invention based on the drawings.

The basic configuration includes a water supply unit 1 largely fitted with a water control device 2 so as to be movable, and a controller unit 3 including a motor 4, 4a, and a P.C.B plate 5.

The nachrome filtration network 15 is installed at the lower side of the water passage 14 located at the bottom of the packing 11. The water regulator (2) is installed at the lower side of the water passage (14), but the rounded fitting member (16) is installed at the top of the water regulator (2) to move the lower portion of the water supply (1). The lower end of the third interlocking member (27b) interlocked with the motor (14a) to be described later by installing a free-flowing, injection-exchange blocking plate (18) which slides freely and slides on the upper side of the water supply passage (17). Combined.

On the other hand, the hand sensor (19) is installed in the bottom peripheral portion of the water regulator (2).

The control unit 3 is provided with two motors 4 and 4a on one side of the inner side, and a motor shaft is provided under the shaft of one of the motors 4 and 4a. A plurality of reduction gears 21 interlocked with 20 are installed, and a cam 23 is installed below the shaft 22 of the final gear 21a among the reduction gears 21, and the cam 23 is It is installed inside the cylinder 24 (piston cover).

In addition, the piston 25 which moves in a horizontal direction in accordance with the rotational motion of the cam 23 is connected to the cam 23 and installed in the cylinder 24. The piston 25 and the water supply part 1 The piston rod 26 is horizontally installed between the hollow balls 10 provided with the bowl bearing 13 (see FIG. 3).

On the other hand, the one side motor 4 is rotated forward and backward so that the cam 23 repeatedly performs 180 ° type forward and reverse rotation during power supply.

A reduction gear is provided on the shaft of the other motor 4a in substantially the same manner as the one motor 4 (not shown in the same shape). The first interlocking member 27 is engaged with the worm gear 28 in contact with the shaft of the final gear, and the second interlocking member 27a and the third interlocking member 27b are engaged with the bevel gear 28 in order to be in motion. The lower end of the third interlocking member 27b is inserted at the bottom of the water control opening 2, and one side circumference of the injection exchange blocking plate 18 is fitted to rotate the third interlocking member 27b. The blocking plate 18 is configured to open and close (see FIG. 4).

On the other hand, a P.C.B plate 5 is installed as one side wall portion of the inner side, and the electronic configurations of the respective parts are controlled by the P.C.B plate 5, that is, the circuit board.

The left and right side surface portions are provided with a touch sensor 30 for controlling the driving of one side driving motor 4 and a blocking plate adjustment detecting sensor 31 for controlling the driving of the other side driving motor 4a. An operation start confirmation buzzer 32 is installed. A power supply battery 33 is built in between the motors 4 and 4a and the P.C.B plate 5.

Looking at the effects of the present invention configured as described above are as follows.

Take a look at blocking the water supply.

First, when a hand touches the touch detection sensor 30 which is a supply cutoff sensor of water (of course, the valve of the faucet must be opened in advance), one side motor 4 starts a forward rotation, for example, in one direction, When the reduction gears 21 and 21a connected to the motor shaft 20 are interlocked in a slow rotation and the cam 23 rotates by 180 °, a relay switch (not shown) is operated to operate the motor 4. Is stopped.

Therefore, at this time, as shown in FIG. 3B, the piston 23 moves to the left side as the cam 23 rotates 180 °, and the tip of the piston rod 2 moves the bowl bearing 13 to the left wall at the same time. Let's do it.

Therefore, the tap water is supplied through the hole 12 because the hole 12 is opened in the center of the packing 11.

On the other hand, when a touch is applied to the touch sensor 30 again, the one side motor 4 is rotated in the opposite direction to the water supply, and the cam 23 also rotates at 180 °. Done.

Therefore, as shown in FIG. 3a, the piston 25 is in the original position, and the bowl bearing 13 is also in the original position, thereby blocking the hole 12 of the packing 11, so that the water supply is blocked.

At this time, the reason why the piston 25 returns to its original position is that when the force applied to the piston 25 is removed as the cam 23 rotates 180 °, the bore bearing 13 naturally opens the hole 12 of the packing 11 by hydraulic pressure. And the hole 12 is blocked, and the ball bearing 13 moving by the hydraulic pressure pushes the piston rod 26 to its original position (right side).

Therefore, when the contact is repeatedly made to the touch sensor 30, the supply and interruption of water is continuously and repeatedly performed by the above operation, the electronic control device as shown in FIG.

By this action, the water supply and shut-off is simply performed by contact without the need to open or lock the water valve in order to save water, so that it is convenient to use and prevents the loss of water.

Hereinafter, the action of water control, that is, direct water and injection. The water control is made by contacting the blocking plate control detection sensor 31, the other motor (4a) is driven by the electronic control to open and close the blocking plate 18 above the water supply passage (17) while directing and spraying Is done.

That is, as the motor 4a is driven, the deceleration force reduced by the reduction gears is interlocked with the first, second and third interlocking members 27, 27a and 27b meshed with the bevel gears 28, respectively. The blocking plate 18 is rotated. At this time, as shown in FIG. 4, the blocking plate 18 is pivotally fitted to the lower end of the third interlocking member 27b, and at the same time, the main wall of the water supply path 17 The end of the third interlocking member 27b is pivotably fitted. Therefore, when the third interlocking member 27b is rotated by the driving of the motor 4a, the blocking plate 18 is driven by the power cutoff of the relay switch when the third interlocking member 27b is rotated forward by 180 degrees. This is stopped.

On the other hand, when the touch again the control plate sensor (31) control sensor 31, as described above, the third interlocking member (27b) is rotated forward by 180 ° by the motor (4a) to block the water supply path (17) As a result, the water is sprayed by passing through a myriad of drill holes 34.

As described above, the water control, that is, the control of the direct water and the injection, is repeatedly performed by the direct water and the injection by contacting the blocking plate control sensor 31. In addition, the hand detection sensor 19 installed at the periphery of the lower end of the water supply unit 1, for example, when approaching a certain distance for washing hands, the motor (4) as the drive of the touch detection sensor 30 described above Is rotated and the piston 25 is operated and the bowl bearing 13 is moved to supply water, and the water is automatically cut off when the hand moves away within the set distance range of the hand sensor 19. Helps Convenience and Water Conservation

This is accomplished by the configuration of the circuit as shown in FIG.

As described above, according to the present invention, according to the configuration of the electronic circuit, each driving motor 4 and 4a rotates to supply water while rotating, and regulates direct water and injection. As a configuration for supplying and blocking water when approaching and moving away, it is possible to provide convenience to use and minimize waste of water.
