Description

Electric cell type fully-automatic water tap

The utility model relates to battery type full-automatic water tap.

Existing automatic faucet mostly is to human body by the body sense element testing on the domestic and international market at present, by signal processing circuit, motor-drive circuit and motor the human body signal that receives is transformed into the rotational position signal of a motor shaft, plays the on-off action in water route by the cooperation of mechanical structure.But existing automatic faucet mostly adopts 220 volts of powers for illumination as power supply, motor is bigger, the water tap volume is big, complex structure need installed electric wire during installation within the walls, and it is loaded down with trivial details to construct, in case down circuitry, maintenance inconvenience, in use circuit and element Chang Yin make moist etc. former thereby cause user's risk of electric shock in addition, also can cause malfunction and waste water resource.

The objective of the invention is to for satisfying market index requests such as water tap economize on electricity, water saving and safety, some shortcomings such as dangerous, the power consumption of eliminating simultaneously that the Ac automatic faucet produces, installation and inconvenient maintenance, and it is compact to design to make every effort to product appearance, small and exquisite exquisiteness, attractive and durable, be applicable to public place and families such as domestic and international hotel, restaurant, station, airport.

Principle of the present invention mainly is a work characteristics of having used for reference domestic and international automatic faucet, adopt body sense element testing human body signal, by with the dryelement cell being the machinery action that the motor-drive circuit of power supply is converted into signal motor shaft, under the effect of the minimum driving force of motor, utilize the differential water pressures of two hydroeciums to finish the make and break process of current.

Accompanying drawing is that figure is cutd open in structural representation of the present utility model.

Water tap of the present invention is motor-drive circuit, motor-driven mechanism and the fire hose main component composition of power supply mainly by the body sense element with the dryelement cell.In embodiment as shown in drawings, used body sense element can be the passive type infrared sensor component, also can adopt sensing elements such as inductance capacitance, microwave ultrasonic wave, is used for finishing human-induced signal's reception.Used driving element-the motor of the present invention can be a DC pulse motor, also can adopt DC micromotor, cooperate optocoupler to realize driving and the location.

When water tap of the present invention was in closed condition, water pipe import 4 ' (with aqueduct link to each other) of water on water tap overcoat 16 entered tap main body member 17, and flowed into hydroecium 12 by water intake 4 wherein, so hydroecium 12 is full of water.Hydroecium 12 is separated by seal ring 6 and hydroecium 11, and hydroecium 11 and inner chamber 14 are by location pin hole 7 and open-work 15 fills with water.At this moment, the seal ring 6 that hydroecium 12 and hydroecium are 11 is in state of equilibrium, and switch letter 5 compresses with waterproof with inner chamber cover outlet member inwall under spring pressure, does not have water in hydroecium 13 that is surrounded by pressure piece 9 and the faucet outlet 10.

In case sense cell 1 is by receiving human body signal (generally being staff) afterwards, make motor 2 through its signal processing system and with the motor-drive circuit 2 of dryelement cell 2 ' be power supply " live axle 3 turn an angle; for example 90 °; and push away fine needle on the partial switch letter 5; simultaneously;; and make switch letter 5 and inner chamber overlap that releasing compresses the formation passage between the 18 outlet member inwalls because the small deflection of switch letter 5, thereby make the water in inner chamber 14 and the hydroecium 11 enter hydroecium 13 through this passage, hydroecium 13 is communicated with faucet outlet 10.Synchronization, because hydroecium 11 pressure reduce, and hydroecium 11 water-fillings are slow (only depending on register pin 7 hole water-fillings), therefore, the balance that hydroecium 11 and hydroecium are 12 is destroyed, seal ring 6 moves to hydroecium 11 directions under hydraulic action, the result makes whole inner chamber cover 18 break away from tight seal together with switch letter 5 with packing ring 8 and contacts and move to hydroecium 11 directions, thereby overlap between 18 outlet member outer walls and the packing ring at inner chamber and to form passage, be communicated with between hydroecium 12 and hydroecium 13 and the water discharge of water faucet 10 like this, water flows out thus for using.

Finish using remove hand after, sense cell 1 signal interruption, motor-drive circuit 2 resets live axle 3, switch letter 5 resets simultaneously, 13 flow channels of hydroecium 11 and hydroecium have just been closed.

Then hydroecium 11 and hydroecium 12 and the very fast water that is full of again of inner chamber 14, spring promote and hydraulic action under, seal ring 6 recovers initial positions, the pathway closure that hydroecium 12 and hydroecium are 13, faucet outlet 10 stops flowing water.

Sense cell 1 waits received signal, enters next circulation.

Can find out that by top detailed description automatic faucet of the present invention has following advantages:

1. adopt dry cell to do power supply, avoided used alternating current automatic faucet causes in the prior art construction, maintenance difficult, safe and reliable.

2. adopt dryelement cell to do power supply, per diem open 200 calculating, the battery mean lifetime surpasses 4 years, and can change battery at any time.

3. because structural design is ingenious, only need the small driving of motor just can finish water flowing, the process of cutting off the water supply, power consumption is extremely low, saves the energy greatly.

4. because the novel structural design of the present invention makes the constant flow of water, the body sense component installation location is reasonable, simultaneously when no human body signal, water tap is closed automatically, therefore, the relative ordinary faucet of the automatic faucet of the present invention 40-60% that can economize on water can be alleviated the water scarcity situation greatly, and economic benefit and social benefit are very remarkable.

5. water tap of the present invention removes switch letter 5, live axle 3 needs to adopt wear-resisting, and for example outside steel, alloy and glass ceramic or the organic material, remaining part such as overcoat, inner chamber etc. all can adopt the ordinary rigid material to corrosion resistant metal, make as plastics, metal and inorganic material, with low cost.

6. easy to use, health is avoided user's cross infection, stops transmission of disease.

Should be understood that and anyly do not breaking away from that being equal to of being done on the essence spirit basis of product of the present invention replaces and small structure changes and all belongs to scope of the present invention.
