The first inductive water outlet device 100 can be used for a faucet. The first inductive water outlet device 100 includes a housing 110, a first control circuit 120, and a driving unit 130. The housing 110 includes a water inlet 111, a first channel 112 and a water outlet 113. The water outlet 113 communicates with the water inlet 111 via the flow channel 112, and a center line of the water inlet 111 and a center line of the flow channel 112 are at a predetermined angle. The water inlet 111 of the housing 110 is used to communicate with the water inlet 111. One of the faucets is out of the water. In this embodiment, the predetermined angle is 90 degrees. The first control circuit 120 is configured to sense a foreign object to generate a control signal. One end 130a of the driving unit 130 is disposed in the housing 110 and is connected to one end 112a of the flow path 112. The driving unit 130 is electrically connected to the first control circuit 120 for controlling the flow or effluent of the fluid of the water outlet 113 according to the control signal. The path of the fluid is sequentially the water inlet 111, the flow path 112, the drive unit 130, and the water outlet 113 (as shown by the direction of the straight arrow 112b in Fig. 3).

The driving unit 130 includes a motor 131 and a valve core 140. The motor 131 is electrically connected to the first control circuit 120. The spool 140 includes a lever 141 and a throttle plate 142. The lever 141 is mechanically coupled to the motor 131. The spool 140 has a plurality of side holes 140a for receiving fluid flowing from the flow passages 112 into the spool 140. The throttle plate 142 is coupled to the control rod 141 and includes a through hole 142a. The through hole 142a corresponds to the water outlet 113. Thereby, when the control rod 141 rotates the throttle plate 142, the overlapping area of the through hole 142a and the water outlet 113 can be adjusted. At this time, the fluid in the spool 140 is further separated from the water outlet 113 by the through hole 142a, thereby controlling the flow rate of the fluid from the water outlet 113. The perforations 142a can be serpentine perforations. The valve body 140 can be a valve core made of metal or ceramic material.

The first control circuit 120 can include a first sensing unit 121 and a second sensing unit 122. The first sensing unit 121 and the second sensing unit 122 are disposed on a circuit board, but the implementation of the present invention is not limited thereto. For example, the first sensing unit 121 can also be configured. The first sensing unit 121 and the second sensing unit 122 can be an infrared sensor or a microwave sensor. The first sensing unit 121 and the second sensing unit 122 can be electrically connected to the circuit board. The first sensing unit 121 is configured to sense a foreign object below the water outlet 113 of the housing 110. For example, when the user's hand position is below the water outlet 113, the first sensing unit 121 senses the appearance of the hand to generate an opening signal, and then transmits the opening signal to the motor 131, and then The rotation of the motor 131 drives the control rod 141 of the valve body 140 and the throttle plate 142, so that the perforation 142a on the throttle plate 142 is aligned with the water outlet 113 to allow fluid to flow out of the water outlet 113. When the user's hand leaves the water outlet 113, the first sensing unit 121 senses the disappearance of the hand to generate a closing signal, and then transmits the closing signal to the motor 131, and then rotates by the motor 131. The control rod 141 and the throttle plate 142 of the valve body 140 are driven to displace the through hole 142a of the throttle plate 142 from the water outlet 113 so that fluid cannot flow out from the water outlet 113.

The second sensing unit 122 is configured to sense an object that is laterally outward of the housing 110. For example, when the user shields the second sensing unit 122 and then leaves the second sensing unit 122, the second sensing unit 122 senses the first occurrence and disappearance of the hand to generate a continuous opening signal. . The continuous opening signal is transmitted to the motor 131, and the rotation of the motor 131 drives the control rod 141 of the valve body 140 and the throttle plate 142 to align the through hole 142a of the throttle plate 142 with the water outlet 113, and the fluid is discharged. It will flow out from the water outlet 113. When the user shields the second sensing unit 122 and then leaves the second sensing unit 122, At this time, the second sensing unit 122 senses the second occurrence and disappearance of the hand to generate a closing signal and transmits it to the motor 131, so that the fluid cannot flow out of the water outlet 113.

In another embodiment, the first control circuit 120 further includes a third sensing unit 123. The third sensing unit 123 can also be used to sense the object that is laterally outward of the housing 110 and the same sensing direction as the sensing direction of the second sensing unit 122. For example, when the user simultaneously shields the second and third sensing units 122, 123 and then leaves the second and third sensing units 122, 123, the second and third sensing units 122, 123 At the same time, the first occurrence and disappearance of the hand is sensed to generate the continuous opening signal and transmitted to the motor 131, so that the fluid flows out of the water outlet 113. Thereafter, when the user only shields the second sensing unit 122, the flow rate of the fluid flowing out of the water outlet 113 continues to increase. When the user only shields the third sensing unit 123, the flow rate of the fluid flowing out of the water outlet 113 continues to decrease. By the action of shielding only the second sensing unit 122 or the third sensing unit 123, the flow rate of the fluid flowing out of the water outlet 113 can be controlled. When the user simultaneously shields the second and third sensing units 122, 123 and then leaves the second and third sensing units 122, 123, the second and third sensing units 122, 123 simultaneously sense The second appearance and disappearance of the hand produces a close signal and is transmitted to the motor 131, so that the fluid cannot flow out of the water outlet 113.

The first control circuit 120 further includes a display light group 124 for displaying different light numbers according to the flow state of the fluid of the water outlet 113. In this embodiment, the display light group 124 can include a red light 124a and a yellow light 124b. For example, when the red light 124a is lit, it may indicate that the flow rate of the fluid flowing out of the water outlet 113 is the maximum state. When the yellow light 124b is illuminated, it can indicate that the flow rate of the fluid flowing out of the water outlet is continuously increasing. In another embodiment, the display light group 124 can be a plurality of light-emitting diodes (LEDs) for illuminating different numbers of light-emitting diodes according to the flow state of the fluid of the water outlet 124.

The first inductive water outlet device 100 can further include: a cover 150 and a battery case 160. The other end 130b of the driving unit 130 and the first control circuit 120 are disposed in the outer cover 150. The battery case 160 is electrically connected to the first control circuit 120 and the driving unit 130, and is also disposed in the outer cover 150. The battery case 160 is provided with a battery for supplying power to the first control circuit 120 and the driving unit 130. When the battery case 160 is disposed in the outer cover 150, the battery case 160 can be fixed in the outer cover 150 by using a battery cover 170. The battery case 160 is designed to prevent the first control circuit 120 and the driving unit 130 from using 110 volts of commercial power, thereby reducing the risk of leakage. The outer cover 150 is used to protect the first control circuit 120, the driving unit 130 and the battery case 160 to prevent the aforementioned components from being damaged by water splashing.

4 is an exploded perspective view of a second inductive water outlet device according to an embodiment of the present invention. The second inductive effluent device 200 is generally similar to the first inductive effluent device 100, like elements being numbered similarly. The second inductive water outlet 200 differs from the first inductive water outlet 100 in that different drive units are used.

One end 230a of the second driving unit 230 is disposed in the housing 210 and is connected to one end 212a of the flow channel 212. The other end 230b of the second driving unit 230 and the second control circuit 220 (without the third sensing unit 123) are disposed in the outer cover 250, and the battery case 260 and the battery cover 270 are disposed on the outer cover 250. The second inductive water outlet device 200 is completed. The second driving unit 230 of the second inductive water outlet device 200 is a solenoid valve 232. One end 230a of the solenoid valve 232 is disposed in the housing 210 and is connected to one end 212a of the flow channel 212. The electromagnetic valve 232 is electrically connected to the second control circuit 220. The second control circuit 220 is configured to sense a foreign object to generate a control signal and transmit the control signal to the electromagnetic valve 232. The solenoid valve 232 controls the water discharge of the fluid of the water outlet 213 according to the control signal.

The second control circuit 220 can include: a first sensing unit 221 and a second sensing unit 222. The first sensing unit 221 and the second sensing unit 222 can be an infrared sensor or a microwave sensor. The first sensing unit 221 is configured to sense an object below the water outlet 213 of the housing 210 . For example, when When the user's hand is below the water outlet 213, the first sensing unit 221 senses the appearance of the hand to generate an opening signal, and then transmits the opening signal to the electromagnetic valve 232, and then the electromagnetic The opening action of the valve 232 causes the fluid to flow out of the water outlet 213. When the user's hand leaves the water outlet 213, the first sensing unit 221 senses the disappearance of the hand to generate a closing signal, and then transmits the closing signal to the solenoid valve 232, and then through the solenoid valve 232. The closing action prevents fluid from flowing out of the water outlet 213.

The second sensing unit 222 is configured to sense an object lateral to the housing 110. For example, when the user shields the second sensing unit 222 and then leaves the second sensing unit 222, the second sensing unit 222 senses the first occurrence and disappearance of the hand to generate a continuous opening signal. . The continuous opening signal is transmitted to the solenoid valve 232, and the fluid is discharged from the water outlet 213 by the opening action of the solenoid valve 232. When the user then shields the second sensing unit 222 and then leaves the second sensing unit 222, the second sensing unit 222 senses the second appearance and disappearance of the hand to generate a shutdown signal. It is sent to the solenoid valve 232 so that the fluid cannot flow out of the water outlet 213.

In addition, according to the equipment system of the inductive water outlet device of the present invention, the housing 110, the outer cover 150 and the battery case 160 of the first inductive water outlet device 100 can be identical to the housing 210 of the second inductive water outlet device 200, The cover 250 and the battery case 260, so that the housing 110, 210, the outer cover 150, 250 and the battery case 160, 260 can reduce the cost during mold opening, and increase the housing 110, 210, the cover 150, 250 And the versatility of the battery cases 160, 260.

Figure 5 is a schematic view showing the usage of the inductive water outlet device. The inductive water outlet device can use the first or second inductive water outlet device described above. Taking the first inductive water outlet device 100 as an example, the water inlet 111 of the first inductive water outlet device 100 is installed at a water outlet 320 of a faucet 300. When the user wants to wash the hand, the hand is placed under the water outlet 113 of the first inductive water outlet device 100, and the water outlet 113 of the first inductive water outlet device 100 flows out of the water. The first inductive water discharge device 100 of the present invention has a predetermined angle (for example, 90 degrees) because the center line of the water inlet 111 and the center line of the flow path 112 are When the first inductive water outlet device 100 is installed at the water outlet 320 of the faucet 300, the water outlet 113 is still at a distance from the bottom of the water washing station 310, and does not cause the first inductive water outlet device to be installed because the faucet 300 is installed. 100 causes the water outlet to be too close to the bottom of the water washing station 310, causing difficulty for the user to use.

FIG. 6 is a schematic diagram of a usage mode of a third inductive water outlet device according to an embodiment of the present invention. Figure 7 is a partial cross-sectional view showing a third inductive water discharge device according to an embodiment of the present invention. The third inductive effluent device 400 is generally similar to the first inductive effluent device 100, like elements being numbered similarly. The third inductive water outlet device 400 is different from the first inductive water outlet device 100 in that the water inlet, the flow channel and the water outlet of the third inductive water outlet device 400 are on the same center line. The structure of the third inductive water discharge device 400 is described in detail below.

One end of the driving unit 430 is disposed in the housing 410, and is connected to the flow channel 412 for controlling the flow or effluent of the fluid of the water outlet 413 according to the control signal.

When the faucet 300 flows out of the water, since the water inlet 411, the flow path 412, and the water outlet 413 are on the same center line, the resistance of the water in the flow path 412 is reduced, so the amount of water is large.

In summary, the first, second and third inductive water outlet devices (hereinafter referred to as water outlet devices) of the present invention can be directly installed in the water outlet of the faucet for convenient installation by a general user.
