Abstract
The utility model relates to a sensing faucet which comprises a pyroelectric infrared detection circuit, a single chip microcomputer control circuit and a drive circuit. Output signals of pyroelectric infrared detection circuit are transmitted to the single chip microcomputer control circuit, and output signals of the single chip microcomputer control circuit are transmitted to the drive circuit. According to the sensing faucet, the pyroelectric infrared detection circuit is used for collecting infrared signals, when people are close to a pyroelectric infrared detection sensor, after a single chip microcomputer delays inside, drive signals are sent out, an electromagnetic valve is opened for releasing water, and automatic controlling is achieved. The sensing faucet is convenient to use and saves water.
Description
Technical field
The utility model relates to a kind of water tap, particularly be a kind of inductive faucet.
Background technique
Water tap has been widely used in fields such as commercial building, family, and the water recloser application circuit of existing water tap is many, and most induction or touchly be controlled to be the master causes the waste of water resources through regular meeting.
The model utility content
The purpose of this utility model is to provide a kind of water saving inductive faucet.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of inductive faucet, comprise rpyroelectric infrared detection circuit, single chip machine controlling circuit and drive circuit, the output signal of described rpyroelectric infrared detection circuit is transferred to single chip machine controlling circuit, and the output signal of described single chip machine controlling circuit sends to drive circuit.
Described rpyroelectric infrared detection circuit adopts HN911T rpyroelectric infrared detecting module A1 to gather human body signal.
Described single chip machine controlling circuit adopts 89S52 single-chip microcomputer IC1.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: this device adopts the rpyroelectric infrared detection circuit to gather infrared signal, when human body when the rpyroelectric infrared acquisition sensor, behind the single-chip microcomputer internal delay time, send the driving signal, open solenoid valve and discharge water, realize control automatically, be i.e. convenient water saving again.
Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of inductive faucet of the present utility model, comprise rpyroelectric infrared detection circuit 1, single chip machine controlling circuit 2 and drive circuit 3, the output signal of described rpyroelectric infrared detection circuit 1 is transferred to single chip machine controlling circuit 2, and the output signal of described single chip machine controlling circuit 2 sends to drive circuit 3.
Described rpyroelectric infrared detection circuit 1 adopts HN911T rpyroelectric infrared detecting module A1 to gather human body signal, connects power supply, and behind 2min, HN911T rpyroelectric infrared detecting module A1 enters acquisition mode automatically approximately.When human body when the rpyroelectric infrared acquisition sensor, the faint infrared energy that human body radiation goes out is picked up by HN911T rpyroelectric infrared detecting module A1, after its internal circuit is amplified processing, its the 1st pin output high level, this signal is input to the 32nd pin I/O end of 89S52 single-chip microcomputer IC1, behind 89S52 single-chip microcomputer IC1 internal delay time, the 26th pin output trigger signal by 89S52 single-chip microcomputer IC1, make the controllable silicon SCR conducting, promote solenoid valve K adhesive, discharge water, after human body leaves, HN911T rpyroelectric infrared detecting module A1 output low level, after 89S52 single-chip microcomputer IC1 internal processes is judged, send control signal, controllable silicon SCR is ended, turn-off solenoid valve K, water tap stops to discharge water.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
