Description
Technical field
The utility model relates to the control device technical field of water purifier, particularly relates to the circuit whether a kind of inside for detecting water purifier leaks.
Background technology
Water purifier is also filtrator, as wastewater treatment.Water purifier said at ordinary times, generally refers to the minifilters used as family.Water purifier, according to different cleaning principles and technique, can divide many types.Generally there are RO counter-infiltration, nanofiltration, ultra filtration membrane, essence filter etc.Water purifier can iron rust, sandstone, colloid and diameter effectively in filtering water all impurity of being greater than 5 microns; Grain active carbon filter core carbon has superpower absorption affinity, can effectively chlorine residue in planar water, smell the chemical agents such as taste, heterochromatic, agricultural chemicals; Accurate activated carbon cartridge, effectively can remove the bacterium, toxin, heavy metal etc. in water.
Major part water purifier adopts the sieved filtration principle progressive structure mode of resistance, formed by multi-stage filter core head and the tail serial connection, filter core precision is arranged in order from low to high, share retain dirt to realize multi-stage filter core, thus reduce filter core blocking and artificial blowdown, the number of times unpicked and washed and extend the cycle of more renew cartridge.A kind of new mentality of designing is also had to be application sub-prime circulation principle self-cleaning frame mode, its design philosophy is no longer to provide space as much as possible and receives dirt for hiding dirt, but take sub-prime principle, isolate sub-fraction clean water, allow again the former water circulation stream that does as usual move up pollution is pulled away in time with current as far as possible simultaneously, reach that Running water never becomes putrid.So both obtained and purified waste water, or can not be not easy again to precipitate dirt in machine, avoid the formation of secondary pollution and greatly alleviate filter core loss, water quality better and safer is energy-conservation low charcoal again.Along with growth in the living standard, the universal of water purifier will be more and more wider, and the product of new technology is meeting the demand of people better.
Existing water purifier, straight drink machine or water dispenser product do not have water leakage inside pick-up unit; leakage inspector is not had to have following deficiency: when machine leaks; the situation of leaking cannot be detected in time automatically and make the protection act of closing water inlet water route, cause machine breakdown.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of leak water detdction circuit of water purifier, whether described circuit leaks for the inside detecting water purifier, if leaked disconnect water route timely, prompting user of service on-call maintenance, prevent mishap from occurring, improve the serviceable life of water purifier.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of leak water detdction circuit of water purifier, it is characterized in that: the first leak water detdction electrode on leak water detdction plate connects the positive pole of the first power supply, the second leak water detdction electrode on leak water detdction plate connects the base stage of triode Q1 through resistance R3, first leak water detdction electrode and the second leak water detdction motor keep interval to arrange, and the positive pole of the first power supply is successively through electric capacity C2 and electric capacity C3 ground connection; The positive pole of second source connects the collector of triode Q1 through resistance R1, the grounded emitter of triode Q1, the collector of a termination triode of electric capacity C1, the emitter of another termination triode of electric capacity C1, the base stage of the one termination triode of resistance R2, the other end ground connection of resistance R2; The node of resistance R1 and electric capacity C1 is feedback signal terminal of leaking, the water leakage input end of this termination water purifier control module.
Described first power supply is+24V, and described second source is+5V.
The beneficial effect adopting technique scheme to produce is: on the line tower foundation of existing controller, increase leak water detdction electrode and feedback circuit, leak water detdction electrode is two panels independently metal electrode, is arranged on water purifier water leakage inside junction.When leaking; two plate electrodes are covered short circuit by water; short-circuit signal feeds back to the control module of water purifier through feedback circuit; enter the pattern of leaking: control module provides instruction and closes entering water electromagnetic valve, supercharge pump, scouring electromagnetic valve etc., in order to protect water purifier, and makes corresponding sound and light alarm; prompting user needs repairing machine; prompting user of service on-call maintenance, prevents mishap from occurring, improves the serviceable life of water purifier.
