Abstract

The utility model relates to the tap controlling field, especially relates to a multi-function tap controlling device. The multi-function tap controlling device is composed of an infrared induction circuit, a single chip microcomputer controlling circuit, a temperature detecting circuit, a displaying circuit, a warning circuit and a controlling drive circuit. The detecting signals of the infrared induction circuit are transmitted to the controlling drive circuit through the single chip microcomputer controlling circuit. The signals of the temperature detecting circuit are transmitted to the displaying circuit for displaying through the single chip microcomputer controlling circuit. The temperature detecting circuit is further connected with the warning circuit through the single chip microcomputer controlling circuit and drives the controlling drive circuit. The controlling device adopts the infrared rays for sensing a human body. When the human body approaches the tap inductor, an electric valve is opened. After the human body leaves, the electric valve is automatically closed in a delayed while. Meanwhile the water temperature is monitored. When the water temperature is higher than a predetermined temperature, an alarm is then given to remind people not to approach with their hands. Therefore, a hand scalding accident or an uncomfortable feeling due to a low water temperature is prevented.

Description

A kind of multi-function water tap control gear

Technical field

The utility model relates to the automatic faucet field, particularly a kind of multi-function water tap control gear.

Background technique

Automatic faucet, in toilet and washroom to user's hand, in kitchen etc., basin and bowl are detected, carry out guttation after detecting automatically, this automatic faucet, because of reasons such as its convenience and wholesomenesses, extensively popularized, but the spray reflection that this automatic faucet produced for when bath can cause misoperation, still can't stop bath when thing moves apart at once automatically detecting, and when water temperature is high, be easy to iron hand.

The model utility content

The purpose of this utility model provides a kind of employing infrared induction human body, monitors the multi-function water tap control gear of coolant-temperature gage simultaneously.

The technological scheme that the utility model adopted is such: a kind of multi-function water tap control gear, form by infrared induction circuit, single chip machine controlling circuit, temperature sensing circuit, display circuit, warning circuit, controlling and driving circuit, the testing signal of described infrared induction circuit passes through single chip machine controlling circuit, connect the controlling and driving circuit, described temperature sensing circuit passes through single chip machine controlling circuit, output to display circuit and show, connect warning circuit, and the drive controlling drive circuit.

Described infrared induction circuit is made up of infrared receiver A1, LM567 decoder A2, triode VT1, electric capacity 1C3, and LM567 decoder A2 connects monostable circuit and triggers A3.

Described temperature sensing circuit by transformer T with after the series circuit of adjustable resistance R, diode D1, resistance R 1 is in parallel, series resistors R2, R3 again, output terminal is connected to the 3rd pin of operational amplifier U4, and the 6th pin output voltage signal of operational amplifier U4 is connected to the 2nd pin of A/D converter U3.

Described infrared receiver A1 adopts the PH506 infrared receiver tube.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this multi-function water tap control gear adopts infrared induction human body, when human body during near the water tap inductor, opens mortor operated valve, after one section time-delay human body leaves, closes automatically.Monitor water temperature simultaneously, when surpassing when water temperature is set, send alarm, the prompting staff is avoided scalding one's hand or water temperature is on the low side brings uncomfortable feeling to people beyond this point.
