2 and 3, the water supply apparatus of the present invention is provided with a bar-shaped rocking bar 100 having a predetermined length. A rotating shaft 110 is formed at the center of the rocking bar 100.

The rocking bar 100 has a bar gear 400. The center of the bar gear 400 coincides with the center of the rotation shaft 110.

The bar gear 400 is gear-connected with the motor gear 320.

The motor shaft 310 is provided on the motor gear 320. One end of the motor shaft 310 is connected to the step motor 300. The other end of the motor shaft 310 is provided with a hand lever 500.

Therefore, the step motor 300 and the hand lever 500 are installed at both ends of the motor shaft 310.

The step motor 300 may be electrically connected to the first control unit 640, and may receive a motion signal from the first control unit 640 to rotate the motor shaft 310 within a predetermined rotation angle range. .

Thus, the first control unit 640 may perform a rotational movement of the motor shaft 310 within a predetermined rotation angle range.

The motor shaft 310 may be rotated within the rotation angle range. The rotational force generated by the motor shaft 310 is transmitted to the motor gear 320, the rotational force transmitted to the motor gear 320 is transmitted to the bar gear 400.

Therefore, the rocking bar 100 connected to the bar gear 400 may repeatedly perform the seesaw movement about the rotation shaft 110.

On the other hand, a pair of push rods 200 are installed on both sides of the bottom of the rocking bar 100 at both sides of the rotation shaft 110 of the rocking bar 100.

Although not shown in the drawings, an elastic spring is installed at the lower end of the push rod 200 to guide the home position return of the push rod 200. Therefore, the push rod 200 forms an up and down movable path along the arrow direction.

The bottom of the push rod 200 is provided with a water supply valve as shown in the Republic of Korea Patent Publication No. 10-2004-0084201.

Therefore, the swinging bar 100 repeatedly performing the seesaw motion as described above may repeat the operation of alternately pressing the pair of push rods 200 along the movable path.

At this time, the push rod 200 which is pressed by the bottom surface of one side of the swinging bar 100 rotates downwards is moved down a certain distance along the movable path, and the lower end of the push rod 200 is compressed by an elastic spring , The water supply valve is opened.

Here, the upper end of the push rod 200 has a first curvature R1. Therefore, the upper outer surface of the push rod 200 is curved.

Accordingly, the upper end of the push rod 200 having the curved surface may be in surface contact with the bottom surface of the rocking bar 100 is the seesaw movement.

Referring to the above configuration, in the case where the power applied to the step motor 300 is cut off, the elastic spring is in the valve closing direction (push rod 200 upward direction) in the inclined state of the swing bar 100 Since the push rod 200 is returned to its original position by the restoring force of the elastic spring and the water supply valve is closed and raised, the rocking bar 100 may be horizontal.

Accordingly, the present invention can prevent the water is wasted due to leakage because the water supply valve is always closed at the time of power failure.

 When it is necessary to supply water to a water tank of a toilet (not shown) by manually operating a water supply valve in a state where power is cut off, the motor gear is operated by rotating the hand lever 500 connected to the motor shaft 310. 320 may be rotated.

After sufficient water is supplied to the water tank of the toilet, the elastic spring, which is compressed by releasing the hand lever 500, raises the push rod 200, and the water supply valve is closed and the swing bar 100 is horizontal. By doing this, the hand lever 500 is returned to its original position.

Accordingly, when the hand lever 500 is rotated by hand, the hand lever 500 is connected to the same shaft as the motor shaft 310, and the rotational force to the motor gear 320 is increased by the gear ratio of the bar gear 400. Because of the transmission, the water supply valve can be easily opened and closed with little force.

On the other hand, referring to Figure 5, the bottom of the rocking bar 100 is formed in the fitting body 120 and the fitting body 120, the fitting groove 121 is fitted to the upper end of the push rod 200 is further Can be formed.

In this case, a first curvature r1 may be formed at an upper end of the push rod 200, and a second curvature r2 greater than the first curvature r1 may be formed at an inner surface of the fitting groove 121. .

Therefore, when the rocking bar 100 repeatedly performing the seesaw motion presses the upper end of the push rod 200, the upper end of the push rod 200 in which the first curvature r1 is formed has the second curvature r2. It may be inserted into the fitting groove 121 may be in contact with the surface.

In addition, since the second curvature r2 is larger than the first curvature r1, the inner surface of the fitting groove 121 serves to guide the upper end of the push rod 200 to be fitted into the fitting groove 121. can do.

Accordingly, when the rocking bar 100 is rotated while tilting to push the upper end of the push rod 200, the push rod 200 can be prevented from being bent to one side or the other side, and further, the push rod 200 ) Can shorten the life of the push rod 200 due to breakage of the top.

Therefore, the guide roller 220 installed at the top of the push rod 210 may be rolled on the bottom surface of the rocking bar 100 rotated downward to be inclined.

Accordingly, when the upper end of the push rod 210 is pressed by the rocking bar 100, friction and impact between the rocking bar 100 and the top of the push rod 210 may be easily absorbed.

Referring to FIG. 7, a guide hole 130 may be further formed on a bottom surface of the rocking bar 100 to contact the rolling surface of the guide roller 220 to roll in a predetermined direction.

In this case, since the guide roller 220 slides along the guide hole 130, when the upper end of the push rod 200 is pressed by the swinging bar 100, the push rod 200 moves to one side or the other side. It can be prevented from bending or the upper end of the push rod 200.

Therefore, referring to FIGS. 5 and 7, the present invention may maintain the opening and closing degree of the water supply valve by preventing the push rod 200 from being separated from the movable path.

On the other hand, the water supply device of the present invention further has a rotation angle detection module 600.

The first control unit 640 calculates a rotation angle range between rotation angles at which the recognition member 620 recognized by the photo sensor 630 is located.

Therefore, the recognition member 620 provided on the rotating shaft of the swinging bar 100 repeatedly performing the seesaw motion is rotated together with the rotating shaft 110.

In this case, the photo sensor 630 may detect a rotation angle range between the rotation angles at which the recognition member 620 is located. Here, since the rotation angles displayed on the rotation angle display unit 610 are preset, the first controller 640 may calculate a rotation angle range by detecting the position of the recognition member 620.

In addition, although not shown in the drawing, the first control unit 640 may be electrically connected to the display unit to visually display the calculated rotation angle range on the display unit.

In addition, the water supply device of the present invention may further include a rotation angle control module 700.
