The drive unit 140 can be a solenoid valve. A power source, such as a dry battery (not shown), is disposed under the housing 110 for providing power to the electronic control unit 130 and the driving unit 140.

Referring to FIG. 3, there is shown a remote mode of a two-stage distance sensing type water supply method according to an embodiment of the present invention: when the sensor 132 senses the presence of the foreign object at a first distance D1, the sensing The signal is an open signal, and the water outlet 116 is supplied with water; and when the sensor 132 senses the disappearance of the foreign object at the first distance D1, the sensing signal is a shutdown signal, thereby causing the signal to be turned off. The nozzle 116 does not feed water. The first distance D1 can be set to 10 to 15 cm. Preferably, the first distance D1 can be set to 12-15 cm. This remote mode provides the right amount of water for hand washing, but must always be placed near the water outlet 116.

For example, when the user's hand appears at a distance from the water outlet 116 (ie, the position of the first distance D1 of the sensor 132), the sensor 132 senses the presence of the hand, and the sensing signal is A signal is turned on. The control circuit 134 receives the sensing signal to generate a control signal. Then, the driving unit 140 opens the fluid from the water outlet 116 according to the control signal.

The second distance D2 can be set to 2 to 8 cm. Preferably, the second distance D2 can be set to 2 to 3 cm. The close-range mode can continue to supply water to provide a large amount of water, but does not have to always have a hand near the water outlet 116.

For example, when the user's hand first appears and disappears near the water outlet 116 (ie, the position of the second distance D2 of the sensor 132, the second distance D2 is smaller than the first distance D1), The sensor 132 senses the presence and disappearance of the hand for the first time, and the sensing signal is an open signal. The control circuit 134 receives the sensing signal to generate a control signal. Then, the driving unit 140 opens the fluid continuously from the water outlet 116 according to the control signal. When the user's hand appears and disappears a second time near the water outlet 116 (ie, the position of the second distance D2 of the sensor 132), the sensor 132 senses for the second time. When the hand appears and disappears, the sensing signal is a turn-off signal. The control circuit 134 receives the sensing signal to generate a control signal. Then, the driving unit 140 closes the fluid from the water outlet 116 according to the control signal.

The operation steps corresponding to the remote mode and the close mode are not limited to the above. In the two-stage distance sensing type water supply method of another embodiment, the operation steps corresponding to the remote mode and the close mode can be mutually adjusted. For example, the proximity mode: when the sensor 132 senses the appearance of the foreign object at a second distance D2, the sensing signal is an opening signal, thereby causing the water outlet 116 to supply water; and when the sensing The sensor 132 senses the disappearance of the foreign object at the second distance D2, and the sensing signal is a closing signal, so that the water outlet 116 does not supply water. The second distance D2 can be set to 2 to 8 cm. The remote mode: when the sensor 132 first senses the appearance and disappearance of the foreign object at a first distance D1 (the first distance D1 is greater than the second distance D2), the sensing signal is one Turning on the signal, so that the water outlet 116 is supplied with water; and when the sensor 132 senses the appearance and disappearance of the foreign object at the first distance D1 for a second time, the sensing signal is a closing signal, thereby enabling The water outlet 116 does not feed water. The first distance D1 can be set to 10 to 15 cm.

According to the two-stage distance sensing type water supply device of the present invention, the electronic control unit includes only one sensor, which can be used simultaneously for the remote mode (first distance) and the close mode (the second distance, which is not equal to the first a sensor of the distance, so the electronic control unit does not need to include more than two sensors, as a sensor for the remote mode and the close mode, thus reducing the number of components of the electronic control unit, Simplify the design of the electronic control unit, thereby reducing the cost of the two-stage distance sensing water supply device.
