Description

Automatic water saving device

Technical field

The present invention relates to a kind of automatic water saving device, be applicable to that family and unit are aspect living water use.

Background technology

China is advocating energy-saving and emission-reduction and strengthen environmental protection always energetically, and this is not only government's duty, also is we each citizen's responsibility.Our reasonable use water resource more in life.Using water wisely has the effect of energy-saving and emission-reduction equally.

Summary of the invention

In life, for reasonable use water resource more, using water wisely is become a very simple thing, the invention provides a kind of automatic water saving device.

The water that automatic water saving device utilizes clean pond to discharge enters storage tank, through twice filtration, decontamination, after removing sediment and floating thing, after the micro pump pressurization, enter accumulator, when the flush toilet water, preferentially supply with the water after handling automatically, when this device lack of water or power failure, can convert the tap water supply pattern automatically to, need not manually-operated.When this device is installed, need not change the structure in flush toilet and clean pond, only need the flush toilet water inlet pipe is connected with normally closed one way valve tap water water inlet and the preferential automatic valve flush toilet of low pressure feed water inlet in the automatic water saving device, clean pond sewer pipe connected with storage tank water inlet pipe and storage tank gutter in the automatic water saving device, connect power supply, the water conservation meeting is finished automatically.This device is rational utilization of water resources more, reduces sewage emissions.

The present invention solves the technical scheme that its problem adopts: automatic water saving device mainly comprises storage tank, micro pump, magnet proximity switch, pressure switch, connection water pipe, unidirectional relief valve, accumulator, the preferential automatic valve of low pressure, normally closed one way valve.

The design feature of storage tank is: at end face water inlet pipe is housed on the storage tank external box of microvave, water inlet pipe is connected with clean pond outlet pipe; In the bottom surface gutter is housed, gutter is connected with sewer; Inspection hatch, draining control handle, fluviograph, fine filtering net maintenance blanking cover are housed in the front; Storage tank delivery port, micro pump, magnet proximity switch, pressure switch, connection water pipe, unidirectional relief valve, accumulator are housed overleaf.Wherein micro pump, magnet proximity switch, accumulator are embedded in the corresponding groove of the storage tank back side.Storage tank inside is equipped with the smelly device of counnter attack, is filtered part flow arrangement, floating thing spilling water window, sediment automatic discharge device, fine filtering device, cursory, the storage tank outlet pipe of magnetic water level, and the storage tank outlet pipe is connected with micro pump.

The work characteristics of storage tank is: the water in clean pond enters the storage tank water inlet pipe and arrives the sieves fie screen through the smelly device of counnter attack, falls into storage tank entry concentrated flow through the fie screen filtration and goes into the storage tank bottom.Impurity and sub-fraction slide into coarse strainer under water, and hair and big impurity rest on above the coarse strainer, fall into gutter water inlet discharge storage tank than small impurities and water.The bottom surface of storage tank is a pan bottom shape, and sediment accumulates in lowest part, and lowest part is provided with outfall and draining is stifled, outfall and draining are stifled is shaped as taper, it is cursory that the stifled top of draining is connected with, and when water storage tank water level was about to reach peak, sediment was removed in the stifled automatic draining of cursory pulling draining.Also can the manually-operated draining.Water intake velocity during greater than drainage speed water level continue to rise, when rising to the 3-5 millimeter, be respectively equipped with the spilling water window in gutter water inlet two sides, floating thing flows into the gutter water inlet by the spilling water window and discharges storage tank.Water in the storage tank arrives micro pump after the fine filtering device filters by the storage tank delivery port, connects water pipe.

Micro pump is electronic micro pump, and electronic micro pump is a known technology, acting as in automatic water saving device: flowing to unidirectional relief valve after the treated water pressurization in the storage tank.Be in series with magnet proximity switch and pressure switch in the micro pump power circuit.Micro pump connects storage tank and unidirectional relief valve by connecting water pipe.

Magnet proximity switch is a known technology, and magnet proximity switch internal circuit and micro pump power circuit are connected in series, acting as in automatic water saving device: by the cursory magnetic intensity of magnetic water level in the induction storage tank, and control micro pump power circuit.Cursory magnetic maximum when nearest of magnetic water level in magnet proximity switch and storage tank, magnet proximity switch control micro pump power circuit disconnects, and micro pump quits work.In the cursory back magnet proximity switch control micro pump power circuit closure of leaving of magnetic water level, micro pump is resumed work.
