- Recently, a common water supply device, e.g., faucet or various water supply pipes, etc. is provided with a rotational switch located thereon for controlling the water supply device to supply water and suitably adjust the water volume, whereby humans can wash their hand so as to prevent from the propagatation and spread of bacteria and virus. During the actual use, in order to prevent a surface of the rational switch from dirt and bacteria on the hand, a user first applies soap to his hand, and then turns on the rational switch, whereby the water supply device can supply clean water to wash the hand so as to finish the washing step.
- However, after the hand is coated with soap and the rational switch is turn on, the surface of the rational switch is still infected with soap together with dist and bacteria. Thus, after the washing step, it is necessary that two hands take water to wash the surface of the rational switch, whereby soap cannot be attached on the rational switch so as to cause the user to have great inconvenience. Furthermore, in the long-term use the water which is used to wash the soap located on the surface of the rational switch is wasted in the water resource so as not to meet the requirement of environmental protection.
- Accordingly, a need remains for a touch free automatic type water supply device to solve the foregoing problems.
- The objective of the present invention is to provide a touch free automatic type water supply device, which can control water flow rate or automatically switch on/off water supply.

For example, when a hand of a user obstructs and then leaves thesecond sensor 122, thesecond sensor 122 senses the first appearance and the first disappearance of the hand and then generates a sustained open signal. The sustained open signal is transmitted to themotor 131, and themotor 131 rotationally drives thecontrol rod 141 and thethrottling plate 142 of thevalve core 140, whereby thethrough aperture 142 a of thethrottling plate 142 and theoutlet 113 are aligned, and the water flows through theoutlet 113. When the hand of the user obstructs and then leaves thesecond sensor 122 again, thesecond sensor 122 senses the second appearance and the second disappearance of the hand and then generates a closed signal. The closed signal is transmitted to themotor 131, whereby the water cannot flow through theoutlet 113. - In another embodiment, the
first control circuit 120 further includes athird sensor 123. Thethird sensor 123 is also adapted to sense the external object located beside theshell 110, and the sensing direction of thethird sensor 123 is the same as that of thesecond sensor 122. For example, when a hand of a user obstructs and then leaves the second andthird sensors third sensors motor 131, whereby the water flows through theoutlet 113. Then, when the hand of the user only obstructs thesecond sensor 122, the water flow rate of theoutlet 113 is continuously increased; and when the hand of the user only obstructs thethird sensor 123, the water flow rate of theoutlet 113 is continuously decreased. Thus, the water flow rate of theoutlet 113 can be controlled by only obstructing thesecond sensor 122 or thethird sensor 123. When the hand of the user obstructs and then leaves the second andthird sensors third sensors motor 131, whereby the water cannot flow through theoutlet 113. - The
first control circuit 120 further includes alight display unit 124 for displaying different light according to the condition of the water flow rate of theoutlet 113. In this embodiment, thelight display unit 124 can include ared light 124 a and ayellow light 124 b. For example, when thered light 124 a is bright, it indicates that the water flow rate of theoutlet 113 is in the maximal condition. When theyellow light 124 b is bright, it indicates that the water flow rate of theoutlet 113 is continuously increased. In another embodiment, thelight display unit 124 can be a plurality of light emitting diodes (LEDs) for brightening different number of LEDs according to the condition of the water flow rate of theoutlet 113. - The first touch free automatic type
water supply device 100 further includes anenvelope lid 150 and abattery container 160. Theother end 130 b of thedriving unit 130 and thefirst control circuit 120 are disposed in theenvelope lid 150. Thebattery container 160 is electrically connected to thefirst control circuit 120 and thedriving unit 130, and is also disposed in theenvelope lid 150. Thebattery container 160 is provided with a battery for supplying electrical power to thefirst control circuit 120 and thedriving unit 130. When thebattery container 160 is disposed in theenvelope lid 150, abattery lid 170 can be further used for mounting thebattery container 160 in theenvelope lid 150. The design of thebattery container 160 can prevent thefirst control circuit 120 and thedriving unit 130 from using the voltage of 110 volts so as to avoid the danger of electric leakage. Theenvelope lid 150 is adapted to protect thefirst control circuit 120, the drivingunit 130 and thebattery container 160 from damage caused by the splashing water. -
FIG. 4 is an exploded perspective view of a second touch free automatic type water supply device according to an embodiment of the present invention. The second touch free automatic typewater supply device 200 is similar to the first touch free automatic typewater supply device 100, and the similar elements have been designated by similar reference numbers. The differences between the second touch free automatic typewater supply device 200 and the first touch free automatic typewater supply device 100 is that: the second touch free automatic typewater supply device 200 uses thesecond driving unit 230, which is different from the drivingunit 130 of the first touch free automatic typewater supply device 100. - An
end 230 a of thesecond driving unit 230 is disposed in theshell 210, and is physically connected to anend 212 a of theflow channel 212. Theother end 230 b of thesecond driving unit 230 and the second control circuit 220 (having no the third sensor 123) are disposed in theenvelope lid 250, and thebattery lid 270 is used for mounting thebattery container 260 in theenvelope lid 250, whereby the second touch free automatic typewater supply device 200 is completed. Thesecond driving unit 230 of the second touch free automatic typewater supply device 200 is asolenoid valve 232. An end (i.e., theend 230 a of the second driving unit 230) of thesolenoid valve 232 is disposed in theshell 210, and is physically connected to theend 212 a of theflow channel 212. Thesolenoid valve 232 is electrically connected to thesecond control circuit 220. Thesecond control circuit 220 is adapted to sense an external object and then to generate a control signal. The control signal is transmitted to thesolenoid valve 232. Thesolenoid valve 232 switches on/off water supply of theoutlet 213 according to the control signal. - The
second control circuit 220 can include afirst sensor 221 and asecond sensor 222. Thefirst sensor 221 and thesecond sensor 222 can be an infrared sensor or a microwave sensor. Thefirst sensor 221 is adapted to sense an external object located below theoutlet 213 of theshell 210. For example, when a hand of a user is put at a position below theoutlet 213, thefirst sensor 221 senses the appearance of the hand and then generates an open signal. The open signal is transmitted to thesolenoid valve 232, and then thesolenoid valve 232 is opened, whereby the water flows through theoutlet 213. When the hand of the user leaves the position below theoutlet 213, thefirst sensor 221 senses the disappearance of the hand and then generates a closed signal. The closed signal is transmitted to thesolenoid valve 232, and then thesolenoid valve 232 is closed, whereby the water cannot flow through theoutlet 213. - The
second sensor 222 is adapted to sense an external object located beside theshell 110. For example, when a hand of a user obstructs and then leaves thesecond sensor 222, thesecond sensor 222 senses the first appearance and the first disappearance of the hand and then generates a sustained open signal. Then, the sustained open signal is transmitted to thesolenoid valve 232, and then thesolenoid valve 232 is opened, whereby the water flows through theoutlet 213. When the hand of the user obstructs and then leaves thesecond sensor 222 again, thesecond sensor 222 senses the second appearance and the second disappearance of the hand and then generates a closed signal. The closed signal is transmitted to thesolenoid valve 232, and then thesolenoid valve 232 is closed, whereby the water cannot flow through theoutlet 213. - In addition, according to a spare part system of the touch free automatic type water supply device of the present invention, the
shell 110, theenvelope lid 150 and thebattery container 160 of the first touch free automatic typewater supply device 100 can be the same as those of the second touch free automatic typewater supply device 200, and theshells envelope lids battery containers shells envelope lids battery containers -
FIG. 5 is a schematic view showing that the touch free automatic type water supply device according to an embodiment of the present invention is used. The touch free automatic type water supply device can be the first touch free automatic typewater supply device 100 or second touch free automatic typewater supply device 200. For example, the first touch free automatic typewater supply device 100 is installed at anoutlet 320 of afaucet 300. When a user washes his hands, at least one of his hands is put at a position below theoutlet 113 of the first touch free automatic typewater supply device 100, whereby the water can flow through theoutlet 113 of the first touch free automatic typewater supply device 100. There is a predetermined angle (e.g., 90 degrees) between the centre line of theinlet 111 and the centre line of theflow channel 112, and thus there is still a predetermined distance between theoutlet 113 and a bottom of a washing basin 310 (i.e., the entire height of the first touch free automatic typewater supply device 100 having 90 degrees between theinlet 111 and theflow channel 112 is smaller than the entire height of the conventional water supply device having 0 degree between the inlet and the flow channel), when the first touch free automatic typewater supply device 100 is installed at theoutlet 320 of thefaucet 300. Accordingly, theoutlet 113 cannot be greatly adjacent to the bottom of thewashing basin 310, and it is not difficult to use the first touch free automatic typewater supply device 100 for user. -
