Description
Technical field
The utility model relates to a kind of water tap, especially a kind ofly can control the break-make of tap water and the water tap of flow automatically.
Background technique
Water is the requisite in daily life materials of people, thereby we will come into contacts with water tap every day.During water, must be by twisting the size that water tap is regulated water flow with hand; Finish using and close with the handgrip water tap again.Ordinary faucet has following shortcoming: 1. and unhygienic, many bacteriums are arranged on the remote holder of washing one's hands, when twisting water tap bacterium is taken on the water tap, wash hand when closing water tap, bacterium is transferred on hand from water tap again.2. lack working life, after use a period of time, the rubber pad of water tap the inside is aging easily, and the consequence that causes water tap to be not closed completely is wasted water.3. if firmly excessive when closing water tap, stripped thread flows away tap water in vain easily, causes great waste.
Summary of the invention
At above-mentioned prior art, the utility model provides a kind of water tap, and it can control break-make and flow, health and the long service life of tap water automatically.
The utility model is achieved through the following technical solutions:
A kind of water tap, comprise intake pipe, outlet pipe and electro-hydraulic proportional throttle valve, wherein, intake pipe is connected on the water intake of electro-hydraulic proportional throttle valve, and outlet pipe is connected on the water outlet of electro-hydraulic proportional throttle valve, on outlet pipe, establish mounting plate, mounting plate is provided with laser range sensor, and laser range sensor is positioned at the below of electro-hydraulic proportional throttle valve, and its range finding face straight down, the mounting plate back side is provided with control circuit, and laser range sensor is connected with electro-hydraulic proportional throttle valve by control circuit.
Described electro-hydraulic proportional throttle valve by electromagnetic steering valve, normally closed selector valve, often drive selector valve, spring, handle and form, laser range sensor is connected with the electromagnetic steering valve of electro-hydraulic proportional throttle valve by control circuit.(electro-hydraulic proportional throttle valve comprises electromagnetic steering valve, normally closed selector valve, often drives selector valve, spring, handle is technique known, does not repeat them here).
Described mounting plate is fixed on the outlet pipe vertically by two fixed card.
The utility model adopts electro-hydraulic proportional throttle valve to control the break-make and the flow of tap water, its working principle is: current signal is inputed to electromechanical conversion equipment (electromagnetic steering valve), latter's output and the proportional power of input current, the axial displacement of make normally closed selector valve, often opening change-over valve core is that axial aperture and the input current in the valve port area of passage is proportional, therefore can be according to the flow of the current signal step-less adjustment tap water of input.
The utility model adopts laser range sensor as monitoring and signal sending element, and its working principle is: linear measure is based on principle of triangulation.Laser beam is beaten and form a point on object, and the receiver of range sensor (photodiode array) is surveyed the position of this point.Reference angle changes with distance, thereby also respective change of the position of laser point on receiver.Photodiode array is read by integrated microcontroller.Controller distributes according to the light on the photodiode array and accurately calculates angle, calculate in view of the above then and object between distance.This distance value is converted to the output current that is directly proportional with distance.This current signal is sent to control circuit, and control circuit has the function of time-delay and signal amplification; Again the amplified current signal is passed to electro-hydraulic proportional throttle valve, and then the control electromagnetic steering valve, thereby the break-make and the flow of control tap water.Therefore, can control the break-make and the flow of tap water by the different distance that laser range sensor monitors.
The utility model can be controlled the break-make and the flow of tap water, hygienic and convenient, long service life automatically.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of water tap, comprise intake pipe 9, outlet pipe 10 and electro-hydraulic proportional throttle valve 6, as shown in Figure 1, wherein, intake pipe 9 is connected on the water intake of electro-hydraulic proportional throttle valve 6, outlet pipe 10 is connected on the water outlet of electro-hydraulic proportional throttle valve 6, establish mounting plate 11 on outlet pipe 10, mounting plate 11 is provided with laser range sensor 1, and laser range sensor 1 is positioned at the below of electro-hydraulic proportional throttle valve 6, its range finding face straight down, mounting plate 11 back sides are provided with control circuit 2.
Described electro-hydraulic proportional throttle valve 6 by electromagnetic steering valve 4, normally closed selector valve 5, often drive selector valve 7, spring 8, handle 3 and form, as shown in Figure 2, wherein, laser range sensor 1 is connected with the electromagnetic steering valve 4 of electro-hydraulic proportional throttle valve 6 by control circuit 2.Electro-hydraulic proportional throttle valve 6 is provided with coil power socket 13.
Described mounting plate 11 is fixed on the outlet pipe 10 vertically by two fixed card 12.
Use: laser range sensor 1 is installed in the below of electro-hydraulic proportional throttle valve 6, the monitoring mouth that makes laser range sensor 1 vertically down, its measuring distance scope is: 50mm-250mm.In the time of in object appears at this scope, laser range sensor 1 converts the distance that measures to current signal at once and passes to control circuit 2, passes to the electromagnetically-operated device 4 on the electro-hydraulic proportional throttle valve 6 after control circuit 2 amplifies this current signal, delay time again.The purpose of amplifying signal is in order to drive the electromagnetically-operated device 4 of electro-hydraulic proportional throttle valve 1; The purpose of time delayed signal is for using water wisely, even if object is appeared in the monitoring range of laser range sensor 1 for a long time, control circuit 2 also can only make the time restriction of output current signal in the time range of design, in case surpass the delay time of control circuit 2, control circuit 2 will cut out output, can only shift out object the monitoring range of laser range sensor 1, and then its monitoring range of shift-in, it is monitored again.
