## Abstract

An intelligent water outlet device includes a water-temperature regulating valve, a water-output control valve, a power source unit, an input unit, a motor drive unit, a first step motor, a second step motor and a control unit. The power source unit energizes the water outlet device. The input unit selects a temperature value for the water output. The motor drive unit drives the first step motor and second step motor, to rotate an adjusting bar of the water-temperature regulating valve and to push a valve bar of the water-output control valve, respectively. The control unit receives a temperature option and an expected water volume from the input unit, and then controls the first step motor and the second step motor to output warm water with the inputted temperature value and the expected water volume.

## Claims

### Claim 1

An intelligent water outlet device, furnished with a water-temperature regulating valve having an adjusting bar and at least one water outlet, a mixing ratio of cold and hot water being adjusted by rotating the adjusting bar, comprising:
a power source unit, receiving a DC power to energizing the intelligent water outlet device;
an input unit, having at least two temperature buttons for inputting different temperature values;
a first step motor, having a rotational power output shaft coaxial and integrally connected with the adjusting bar of the water-temperature regulating valve, the power output shaft being used for rotating the adjusting bar;
a motor drive unit, used for driving the first step motor and providing the first step motor to perform a positive rotation, a negative rotation and a 0-degree calibration;
a control unit, used for receiving the temperature value inputted at the input unit, and transmitting a message to the motor drive unit for driving the power output shaft of the first step motor to rotate the adjusting bar of the water-temperature regulating valve to a corresponding angle so as to have the water-temperature regulating valve to output warm water having the inputted temperature value; and
a water outlet pipe, a water-output control valve disposed at the water outlet pipe, and a second step motor; wherein one end of the water outlet pipe is connected with the water outlet of the water-temperature regulating valve; wherein the water-output control valve is furnished with an oblique-push valve bar for providing an angle of inclination to determine the water output of a water-supply adjusting valve; wherein the second step motor has a telescoping power output shaft driven by the motor drive unit, and the power output shaft is pivotally connected with the valve bar.

### Claim 2 (depends on 1)

The intelligent water outlet device of claim 1, wherein the input unit is furnished with at least two water-feeding buttons for different water volumes, and the control unit drives the second step motor of the motor drive unit to protrude a power output shaft thereof by a predetermined length according to the inputted water volume at the input unit.

### Claim 3

An intelligent water outlet device, furnished with a water-temperature regulating valve having an adjusting bar and at least one water outlet, a mixing ratio of cold and hot water being adjusted by rotating the adjusting bar, comprising:
a power source unit, receiving a DC power to energizing the intelligent water outlet device;
a first step motor, having a rotational power output shaft coaxial and integrally connected with the adjusting bar of the water-temperature regulating valve, the power output shaft being used for rotating the adjusting bar;
a motor drive unit, used for driving the first step motor and providing the first step motor to perform a positive rotation, a negative rotation and a 0-degree calibration;
an input unit, having at least two temperature buttons for inputting different temperature values;
a water-temperature detecting unit, used for detecting a real-time water temperature inside the water-temperature regulating valve and then transmitting the real-time water temperature to the control unit; and
a control unit, used for receiving the temperature value inputted at the input unit and the real-time water temperature detected by the water-temperature detecting unit, transmitting a corresponding message to the motor drive unit for driving the power output shaft of the first step motor to rotate the adjusting bar till when the inputted temperature value is equal to the detected real-time water temperature, and then having the motor drive unit to stop the first step motor;
wherein, when a temperature difference between the inputted temperature value and the detected real-time water temperature exceeds a preset allowable temperature difference, the control unit has the motor drive unit to reactivate the first step motor till when the detected real-time water temperature is equal to the inputted water temperature, and then has the motor drive unit to stop the first step motor.

### Claim 4 (depends on 3)

The intelligent water outlet device of claim 3, wherein the allowable temperature difference is ±0.5° C.

### Claim 5 (depends on 3)

The intelligent water outlet device of claim 3, further including a water outlet pipe, a water-output control valve disposed at the water outlet pipe, and a second step motor; wherein one end of the water outlet pipe is connected with the water outlet of the water-temperature regulating valve; wherein the water-output control valve is furnished with an oblique-push valve bar for providing an angle of inclination to determine the water output of a water-supply adjusting valve; wherein the second step motor has a telescoping power output shaft driven by the motor drive unit, and the power output shaft is pivotally connected with the valve bar.

### Claim 6 (depends on 5)

The intelligent water outlet device of claim 5, wherein the input unit is furnished with at least two water-feeding buttons for different water volumes, and the control unit drives the second step motor of the motor drive unit to protrude a power output shaft thereof by a predetermined length according to the inputted water volume at the input unit.
