A spindle 15 having a driven gear 14 is coupled to the upper side of the valve body 11, and the driven gear 14 is a prime mover coupled to a motor 16 operated by a power source applied from a battery 16a. The gear 17 is engaged.

In addition, a switch 18 for driving the motor 16 is provided at an outer side of the main body 10, and a handle 19 is coupled to the spindle 15.

Therefore, when the switch 18 is operated, power is applied from the battery 16a to operate the motor 16, and the driven gear 17 rotated by the operation of the motor 16 and the driven gear engaged therewith ( 14 rotates, and when the spindle 15 rotates to open the valve body 11 by the rotational operation of the driven gear 14, water introduced through the water supply pipe 12 is discharged through the water discharge port 13. It is discharged.

However, such a conventional technique can be adjusted to some extent by simply operating the valve body by rotating the spindle, but it is not applicable to the case of discharging cold or hot water. There are several problems, such as the inconvenience of having to replace the battery after a certain amount of time.

In addition, when cold or hot water is used, it is difficult for a user to check the temperature of the mixed water discharged. Accordingly, when hot water is discharged at a high temperature, there is a problem such as burning.

The present invention has been invented to solve the above problems, it is an object of the present invention to provide a faucet automatic opening and closing device that automatically adjusts the water temperature and quantity.

Another object of the present invention is to provide a faucet automatic opening and closing device that is very convenient to use, so that the water temperature and quantity can be adjusted manually or automatically.
