Abstract

The utility model relates to a solenoid valve faucet controller which comprises an infrared pulse transmission module, an infrared reception module, a decoding module and a control module. Infrared pulse modulating waves output by the infrared pulse transmission module are transmitted to the infrared reception module which converts infrared light into electrical signals. The electrical signals are transmitted to the decoding module through an amplification module. Output signals of the decoding module are sent to a drive control module. According to the solenoid valve faucet controller, the infrared interruption principle is adopted for control, automatic and instant water supply and automatic and delayed water break can be achieved. The solenoid valve faucet controller is convenient and water saving and can be used in public places.

Description

A kind of solenoid valve faucet controller

Technical field

The utility model relates to a kind of controller, particularly be a kind of solenoid valve faucet controller.

Background technique

Existing solenoid valve faucet controller is widely used in the source of cutting off the water supply that opens or closes of water tap, but all adopts the mechanical adjustment structure as the one of which, when coming inconvenience to people, also often causes the waste of water resources.

The model utility content

The purpose of the utility model is to provide a kind of solenoid valve faucet controller.

The utility model solves the technological scheme that its technical problem adopted: a kind of solenoid valve faucet controller; Comprise infrared pulse transmitter module, infrared receiving module, decoding module and control module; The infrared pulse modulated wave of said infrared pulse transmitter module output transfers to infrared receiving module; Infrared receiving module converts infrared light into electrical signal, and transfers to decoding module through amplification module, and the output signal of said decoding module is sent to drive control module.

Preferably, the output terminal of the astable multivibrator that is made up of 555 time base circuit IC1 and peripheral resistance R 1, resistance R 2, the capacitor C 1 that connects thereof of said infrared pulse transmitter module connects two VD1, VD2 infrarede emitting diodes and forms.

Preferably, said infrared receiving module constitutes with VD1, the supporting infrared reception triode of VT1, VT2 of VD2 infrarede emitting diode by two.

Preferably, said amplification module adopts CA741 amplifier IC2.

Preferably, said decoding module adopts the tone decoder IC3 of LM567 phaselocked loop.

Preferably, said drive control module connects ac solid relay IC4 control electromagnetic valve through field effect transistor VT3 output.

Through adopting above-mentioned technological scheme, the beneficial effect of the utility model is: the utility model adopts the control of infrared interrupter-type principle, and this controller can be instantaneous automatically comes water, and automatic time delay is cut off the water supply, and promptly conveniently economizes on water again, can be used for the public place.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Like Fig. 1, shown in Figure 2; A kind of solenoid valve faucet controller of the utility model; Comprise infrared pulse transmitter module 1, infrared receiving module 2, decoding module 3 and control module 4, the infrared pulse modulated wave of said infrared pulse transmitter module 1 output transfers to infrared receiving module 2, and infrared receiving module 2 converts infrared light into electrical signal; And transferring to decoding module 3 through amplification module 21, the output signal of said decoding module 3 is sent to drive control module 4.

Said infrared pulse transmitter module 1 is made up of output terminal connection two VD1, VD2 infrarede emitting diodes of the astable multivibrator that 555 time base circuit IC1 and peripheral resistance R 1, resistance R 2, the capacitor C 1 that connects thereof constitute; The oscillation frequency f=1.44/ of astable multivibrator [(R1+2R2) C1]; Be about 40kHz; It drives two VD1, VD2 infrarede emitting diode, produces the infrared pulse modulated wave.

Said infrared receiving module 2 constitutes with VD1, the supporting infrared reception triode of VT1, VT2 of VD2 infrarede emitting diode by two; Be used for converting infrared light into electrical signal; And through being connected to the tone decoder IC3 of LM567 phaselocked loop after the CA741 amplifier IC2 amplification; Regulator potentiometer RP1 makes the infrared modulated frequency 40kHz of CF center frequency fo=1/ (1.1RP1C6) emission of tone decoder IC3 of LM567 phaselocked loop consistent.

When human infrared signal arrives, the 8th pin output low level of the tone decoder IC3 of LM567 phaselocked loop, field effect transistor VT3 ends, and ac solid relay IC4 does not have control signal to be triggered, and it exchanges output and is in off state.

And wash one's hands when infrared beam blocked as the people; The tone decoder IC3 no signal input of LM567 phaselocked loop; The 8th pin of the tone decoder IC3 of LM567 phaselocked loop makes field effect transistor VT3 conducting because of the high level biasing of resistance R 7 is high level state, and ac solid relay IC4 has pulse (greater than the 2-6V) signal of a saltus step because of control end; And its alternating voltage is connected, make that the solenoid valve of water tap is opened automatically, discharge water; After staff leaves; Infrared light shines again and receives on the head; The 8th pin output terminal of the tone decoder IC3 of LM567 phaselocked loop recovers low level again by high level, and field effect transistor VT3 ends, and the interchange output of ac solid relay IC4 is also broken off; Reach the purpose that water tap control opens or closes the source of cutting off the water supply, normal water supply and using water wisely are provided.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
