Description
Technical field
Technical field more particularly to a kind of household faucet leakage protective system the utility model is related to tap leakproof.
Background technology
With the rapid development of economy, the people’s lives rhythm for staying in a tier 2 cities is constantly accelerated, cause people every
, all in busy state, this causes people that can inevitably forget some trifle things when doing work, and such as finishes watching TV and forgets for it
Note is closed, when washing hand or because other accidents are forgotten to turn off the tap.Television set forgets to close some electricity of waste at the worst
Take, but if tap is forgotten to close, may result in water always toward leakage, cause ponding, damage furniture and household electrical appliances.
In order to avoid the above situation, mostly currently on the market is using infrared tube induction technology, when hand is extended through water by someone
At faucet water outlet opening, tap can be just discharged.But the technology is used, water flow cannot control, accordingly even when only needing a small amount of water just
It can complete to clean, tap can also flow out a large amount of tap water, cause the waste of tap water.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and make user's tap safe to use clear
Wash, in the case where forgetting to turn off tap will not leak, the household faucet leakage protective system of water resource can be saved.
To achieve the above object, technical solution provided by the utility model is：Including tap, running water pipe, leakproof
Device；Tap is installed in running water pipe one end, and leak-proof device is mounted on running water pipe, and close to tap；Wherein, it is described
Leak-proof device includes power supply unit, microcontroller, switch control unit and sensing unit；Power supply unit respectively with microcontroller, open
Control unit and sensing unit connection are closed, is microcontroller, switch control unit and sensing unit power supply；Microcontroller is connected to
Between sensing unit and switch control unit, by sensing unit send transducing signal processing analysis after send control instruction to
Switch control unit controls the closure of switch control unit.
Further, said supply unit include be sequentially connected in series power supply rectification filter circuit, switch oscillating circuit,
Impulse commutation filter circuit and the sampling voltage stabilizing being connect respectively with impulse commutation filter circuit and switch oscillating circuit control electricity
Road.
Further, the switch control unit is solenoid valve.
Further, the sensing unit is pyroelectric infrared sensor.
Compared with prior art, the operation principle of this programme is as follows：
When pyroelectric infrared sensor detects that someone is at faucet outlet, pyroelectric infrared sensor output
One signal is to microcontroller, and after microcontroller detects this signal, microcontroller is to signal processing analysis and exports a control
Signal goes control solenoid valve to open, and user not only can just commonly use water, but also can be by twisting tap after opening tap at this time
Twist switch control tap water flow velocity；When pyroelectric infrared sensor detects that people is left at tap outlet, heat is released
Electric another signal of infrared sensor output is to microcontroller, and microcontroller will be after delay a period of time, one control signal control of output
Solenoid closure processed, tap water stop outflow, realize the function of preventing water leakage.
Compared with prior art, it has the following advantages：
1st, when people is left at faucet outlet, solenoid valve may turn off, and automatically cuts off the tap water of tap, avoids
There is people not in tap water also always to the situation of leakage.
2nd, when people is at faucet outlet, solenoid valve will be opened, and need the tap water of much flow velocitys, pass through twisting
The twist switch of tap realizes, suitable people's needs whiles will not waste tap water.
Description of the drawings
Fig. 1 is a kind of entire block diagram of household faucet leakage protective system of the utility model；
Fig. 2 is the module map of power supply unit in a kind of household faucet leakage protective system of the utility model.
Specific embodiment
With reference to specific embodiment, the utility model is described in further detail：
Referring to shown in attached drawing 1-2, a kind of household faucet leakage protective system described in the present embodiment, including include tap 1,
Running water pipe, leak-proof device 2；Tap 1 is installed in running water pipe one end, and leak-proof device 2 is mounted on running water pipe, and close
Tap 1；Wherein, the leak-proof device 2 includes power supply unit 3, microcontroller 4, switch control unit 5 and sensing unit 6；For
Electric unit 3 is connect respectively with microcontroller 4, switch control unit 5 and sensing unit 6, be microcontroller 4, switch control unit 5 with
And sensing unit 6 is powered；Microcontroller 4 is connected between sensing unit 6 and switch control unit 5, and sensing unit 6 is sent
Control instruction is sent after transducing signal processing analysis to switch control unit 5, controls the closure of switch control unit 5.
Sensing unit 6 uses pyroelectric infrared sensor, and switch control unit 5 uses solenoid valve.
Power supply unit 3 is whole including the power supply rectification filter circuit 3-1, switch oscillating circuit 3-2, pulse being sequentially connected in series
Stream filter circuit 3-3 and the sampling voltage stabilizing control being connect respectively with impulse commutation filter circuit 3-3 and switch oscillating circuit 3-2
Circuit 3-4.220V AC voltage is by exporting the DC voltage for 300V, the DC voltage after power supply rectification filter circuit 3-1
Using switch oscillating circuit 3-2 voltage pulse outputs, finally by impulse commutation filter circuit 3-3 output stable DC 5V electricity
Pressure and stable DC 12V voltages.The pulse signal of output is adjusted by sampling controlling circuit of voltage regulation 3-4 during this.
The operation principle of the present embodiment is as follows：
When pyroelectric infrared sensor detects someone close to 1 water outlet of tap, pyroelectric infrared sensor is defeated
Go out a signal to microcontroller 4, after microcontroller 4 detects this signal, microcontroller 4 is to signal processing analysis and output one
Control signal goes control solenoid valve to open, and user not only can just commonly use water, but also can be by twisting water after opening tap 1 at this time
The flow velocity of the twist switch control tap water of tap 1；When pyroelectric infrared sensor detects that human hand has left tap 1 and exported
During place, another signal of pyroelectric infrared sensor output to microcontroller 4, microcontroller 4 will be delayed after a period of time, export one
Signal control solenoid closure is controlled, tap water stops outflow, realizes the function of preventing water leakage.
In the present embodiment when people leaves 1 water outlet of tap, solenoid valve may turn off, automatically by tap 1 from
Water is cut off, and avoids the occurrence of people not in tap water also always to the situation of leakage.When human hand stretches into 1 water outlet of tap,
Solenoid valve will be opened, and need the tap water of much flow velocitys, be realized by twisting the twist switch of tap 1, be suitble to people
Tap water will not be wasted while needs.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore the variation that all shape, principles according to the utility model are made, should all cover in the scope of protection of the utility model
It is interior.
