Infrared opposite type faucet switch

[0011] Such as figure 1 As shown, the infrared directing faucet switch includes an infrared signal transmitter 1, an infrared signal receiver 2, the infrared signal receiver is connected to the controller 3, and a solenoid valve 4 is connected to the controller 3, which is responsible for the opening and closing of the faucet. The infrared signal transmitter 1 continuously transmits infrared signals to the infrared signal receiver 2. When the faucet is unused, the infrared signal receiver 2 can sense the infrared signal emitted by the infrared signal transmitter 1. When the user's hand is placed under the faucet, the infrared signal emitted by the infrared signal transmitter 1 is blocked by the hand, and the infrared signal receiver 2 senses a signal interruption, and the controller 3 connected to the infrared signal receiver 2 detects this. After the signal is interrupted, it is judged that someone is using the faucet, and the solenoid valve 4 is instructed to open, so that the

[0014] Such as figure 2 As shown, the infrared direct-firing faucet switch can also be designed so that a plurality of serially arranged infrared signal transmitting and receiving devices detects the user's actions and completes the corresponding switching action. The infrared signal transmitting terminal 5 and the infrared signal transmitting terminal 7 are arranged vertically and serially, and the infrared signal receiving terminal 6 and the infrared signal receiving terminal 8 are also arranged vertically and serially and are connected to the controller 3 . The infrared signal transmitter 5 continuously sends infrared signals to the infrared signal receiver 6 , and the infrared signal transmitter 7 continuously sends infrared signals to the infrared signal receiver 8 . The space between the above four infrared signal devices forms a signal sensing area. When the user's hand or other objects pass through the sensing area from top to bottom, the infrared signal receiving end 6

[0017] Such as figure 2 As shown, the infrared directing type faucet switch can also be designed so that when the user opens the faucet with a gesture, the faucet will be automatically closed after a period of time. When the user's hand or other objects block the infrared signal emitted by the infrared signal transmitter 5 or the infrared signal transmitter 7, the infrared signal receiver 6 or the infrared signal receiver 8 senses an interruption of the infrared signal. The controller 3 detects the interruption of the infrared signal, judges that a user is using the faucet, instructs the solenoid valve 4 to open, and counts for a period of time. After the timing ends, the instructs the solenoid valve 4 to close, and the faucet stops water discharge.
