Embodiment 1

[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 t...

Embodiment 2

[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...

Embodiment 3

[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.

Abstract

The invention discloses an infrared opposite-beam faucet switch, comprising an infrared signal transmitter and an infrared signal receiver. The infrared signal receiver is connected with a controller through a signal line, and the controller is connected with a solenoid valve. When the faucet is working, the infrared signal transmitter continuously transmits infrared signals to the infrared signal receiver. When the user's hand or other objects cross the position between the signal transmitter and the signal receiver, the infrared signal is blocked, and the signal receiver senses. After the interruption of a signal is detected by the controller, the controller instructs the solenoid valve to open or close to realize the opening and closing of the faucet. The invention utilizes real-time detection of the on-off of the infrared opposite-radiation signal to judge the intention of the user of the faucet, and then controls the action of the solenoid valve, and has the advantages of high sensitivity and no accidental opening due to environmental influences.

Description

technical field [0001] The invention relates to sanitary equipment, in particular to a faucet switch. Background technique [0002] The control part of the existing automatic induction faucet is made by utilizing the principle of infrared signal reflection. When the user's hand enters the infrared signal sensing area, the infrared rays emitted by the infrared signal transmitting tube are reflected to the infrared receiving tube due to the shielding of the human hand, and then the controller directs the opening and closing of the water pipe solenoid valve according to the signal from the infrared receiving tube. Because the intensity of infrared signal reflection is related to the position and angle of the user's hand, sometimes the faucet cannot sense objects in the sensing area and automatically open. In addition, in some cases, the infrared receiving tube may output a signal to the controller under the irradiation of infrared rays in the natural environment, and the fauce...
