Abstract

Disclosed is an environmental protection water saving secondary closet cistern which is characterized in that a tunicatus box body structure is adopted and the utility model is composed of an external water storage cistern and an internal water cistern; a drainage valve is arranged in the internal water cistern, and the internal water cistern is directly communicated with the external water storage cistern through a water hole on the lower section of the side of the internal water cistern; the external water storage cistern is provided with two water inlets, one water inlet is for city water, and the other water inlet is for secondary water; a water inlet pipe of float valve structure is arranged on the water inlet for city water, an overflowing water pipe is communicated with a water outlet, and the height of the pipe mouth of the overflowing water pipe is higher than the top of the internal water cistern and lower than the top of the external water storage cistern; an air hole is positioned on the top cover of the internal water cistern, and a vent pipe is arranged on the air hole. The utility model adopts the tunicatus box body, which can effectively increase water storage capacity and be useful for storing the secondary water on one hand and can effectively restrict water consumption for primary wash by using the internal water cistern on the other hand.

Description

Environment-friendly water-saving secondary toilet water storage tank

Technical field:

The utility model relates to the toilet water storage tank.

Background technology:

According to measuring and calculating, in an average family, the toilet water supply volume is 1/3rd of family's daily water consumption.In fact, no matter be in some public arenas or average family, for the order that reaches water saving, reduce the consumption to water resource, the toilet water can be the secondary water through using fully.Such as, washing machine drainage, doing the wash pond draining etc. can be as the toilet water.But present employed water-closet tank can not be used for cooperating this water saving mode of realization.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of environment-friendly water-saving secondary toilet water storage tank is provided, make water-closet tank can effectively utilize secondary water, reduce the purpose that the consumption of water resource is reached water saving, reduce effluent discharge to reach the purpose of environmental protection.

The technical scheme that the utility model technical solution problem is adopted is:

Design feature of the present utility model adopts nestable body structure, constitute by outside water storage tank and inner water-tank, draining valve is arranged in inner water-tank, described inner water-tank directly is communicated with outside water storage tank with the little water hole of its side bottom, outside water storage tank has two water inlets of height, first tap water water inlet, it two is secondary water water inlets, water inlet pipe with floating ball valve structure is set on the tap water water inlet, overflow pipe is communicated with outfall, the mouth of pipe height of overflow pipe is higher than the top of inner water-tank, and be lower than the top of outside water storage tank, and on the top cover of described inner water-tank, have pore, ventilating pipe is set on the pore.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model adopts nestable body structure, effectively increases its water storage capacity on the one hand, is beneficial to the seasoning of secondary water; Effectively limit the water supply volume of once flushing on the other hand with inner water-tank.

2, the utility model obtains rationally water resource and utilizes fully, because of reducing the sewage emissions amount, and reaches the purpose of environmental protection in water saving.

The drawing explanation:

Accompanying drawing is the utility model structural representation.

Number in the figure: 1 outside water storage tank, 2 inner water-tanks, 3 draining valves, 4 little water holes, 5 tap water water inlets, 6 secondary water water inlets, 7 water inlet pipes, 8 float valves, 9 overflow pipes, 10 outfall, 11 ventilating pipes.

The specific embodiment:

Referring to accompanying drawing 1, present embodiment is to adopt nestable body structure, constitute by outside water storage tank 1 and inner water-tank 2, draining valve 3 is arranged in inner water-tank 2, inner water-tank 2 directly is communicated with outside water storage tank 1 with the little water hole 4 of its side bottom, outside water storage tank 1 has two water inlets, first tap water water inlet 5, it two is secondary water water inlets 6, water inlet pipe 7 with floating ball valve structure is set on tap water water inlet 5, float valve 8 is arranged on the top of water inlet pipe 7, overflow pipe 9 is communicated with outfall 10, and the mouth of pipe height of overflow pipe 9 is higher than the top of inner water-tank 2, be lower than the top of outside water storage tank 1, on the top cover of inner water-tank 2, have pore, ventilating pipe 11 is set on the pore, and the mouth of pipe height of ventilating pipe 11 is higher than the mouth of pipe height of overflow pipe 9.

In concrete the enforcement, tap water water inlet 5 is positioned at the bottom of outside water storage tank 1, and secondary water inlet 6 can be arranged on the optional position of outside water storage tank 1, comprises being positioned at its both sides, top, and is positioned at the bottom shown in the figure.

Because the bore of outfall 10 is bigger, and little water hole 4 diameters that are communicated with between inner water-tank 2 and outside water storage tank 1 are less, therefore, and when startup draining valve 3 carries out draining, what directly discharge is water storage in the inner water-tank 2, and being provided with of ventilating pipe 11 can make that draining is smooth and easy to be carried out.After draining was finished, draining valve 3 cut out, and by in little water hole 4 water filling inner water-tanks 2, from ventilating pipe 11 discharge again by the air in the inner water-tank 2 for the water storage in the outside water storage tank 1, in order to reusing.

In concrete the enforcement, the capacity of inner water-tank 2 is the water yield of once flushing, and the Lift of float valve 8 should be in the top cover position of inner water-tank 2, to keep the liquid level in the inner water-tank 2.The injection of secondary water is at any time, not controlled by float valve, and liquid level is limited on the mouth of pipe height of overflow pipe 9.Make drop that displacement forms in external water storage tank less than the difference in height between the top cover position of the nozzle position of overflow pipe 9 and inner water-tank 2 in order to use secondary water as far as possible, should to be provided with.Like this, when outside water storage tank 1 when full, after the draining, liquid level still is higher than the Lift of float valve, and float valve remains the pass, preferentially waits for the injection of secondary water, if make liquid level be lower than the cap height of inner water-tank 2 continuously, then float valve is opened, and is replenished by tap water, to guarantee normal use.

Mode of occupation is as follows:

1, when not having the injection of secondary water, when liquid level is lower than the Lift of float valve 8, float valve 8 is opened, pass through float valve 8 water filling in outside water storage tank 1 by tap water water inlet 5, since directly be communicated with, water inlet simultaneously in the inner water-tank 2, and air is discharged from from ventilating pipe 11, reach desired location until liquid level, float valve 8 is closed.

2, when the injection of secondary water is arranged, be lower than the Lift of float valve 8 when liquid level, float valve 8 is opened, tap water and secondary water inject simultaneously, reach desired location until liquid level, float valve 8 is closed, and secondary water continues to inject, make liquid level continue to raise, the height of liquid level can reach the height of the overflow pipe mouth of pipe.

3, the Lift that is higher than float valve when liquid level, float valve 8 keeps closing, and the injection of secondary water raises liquid level, and the height of liquid level can reach the mouth of pipe height of overflow pipe 9.

4, close the tap water water valve that is arranged on the water storage tank outside, cut off the tap water water source, the injection of secondary water raises liquid level, and the height of liquid level can reach the height of the overflow pipe mouth of pipe.
