Abstract

The utility model relates to a two-stage water-saving device for a closet, which comprises a water tank 1, an upper cover 2, a water storage control device 3, a first flushing control device 4 provided with a first trigger mechanism 41 and a first connecting object 42, a flushing path inlet 44, a cover 43 of the flushing path inlet 43 and an overflow pipe 6, a second flushing path inlet 54 and a cover 53 of the second flushing path inlet 54 and a second flushing control device 5. When the water requirement is small, a second flushing trigger mechanism 51 and a wire rope 52 are used for opening the cover 53 of the second flushing path inlet 54. Only half of the water in the water tank is needed to flush the closet, the effects of saving water are obvious. Funds can be saved for families and the society, waste is reduced, and the utility model is favorable for protecting precious water resources.

Description

The two-stage type water saving device of toilet bowl

The utility model relates to the control technology of indoor sanitaryware water, particularly the grading control technology of flush toilet water.

In the society, flush toilet is widely-used now; Do not monopolize in the family of absolute majority, used the flush toilet of sitting posture or crouching formula; Especially in civilization flourishing country and area, flush toilet has almost all been used in the lavatory of public place.The benefit of flush toilet is instant bath, and not only health, few stink the more important thing is that its water tank has automatic control function, and the nonrecoverable water yield is fixed, and can not stop by permanent current the waste precious water resource.But people use the lavatory, and the branch of stool urine is arranged, and are generally more towards stool institute water requirement, less towards the urinal water requirement.The single stage type water box of water closet that face uses now all must design by maximum water supply volume, promptly by the required discharging quantity of water design of stool, could satisfy hygienic requirements.Just there is a problem in this, and also with excessive water flushing, the water yield of being wasted is very surprising when promptly having only urine.Civilized city with 2,000,000 populations is an example, if on average urinate 1 time stool for each person every day for 3 times, by standard water tank 0.02M ³Meter, then the total water amount is 2,000,000 ^*4 ^*0.02=160000M ³Promptly 160,000 tons, wherein necessary water supply volume is 100,000 tons, and the water of waste is 60,000 tons, accounts for necessary water supply volume 60%.

The utility model proposes a kind of water yield that can control once bath automatically at above-mentioned the deficiencies in the prior art part, two-stage type water saving device of toilet bowl that can also grading control, allow the user select, reach water-saving purpose by the difference of institute's water requirement.

The purpose of this utility model can reach by adopting following technical measures:

Manufacture and design a kind of two-stage type water saving device of toilet bowl, comprise water tank, loam cake, water-storage controller and contain first trigger mechanism and first flushing control apparatus of first attachment, bath road import, bath road access cover and overflow pipe, also the second bath road import and the second bath road access cover are set, and second flushing control apparatus that contains second trigger mechanism and second attachment is set at the overflow pipe waist; Like this, trigger second flushing control apparatus in water requirement more after a little while, only need the water of half to dash toilet, water saving significantly; And water requirement triggers first flushing control apparatus more for a long time, also can guarantee sanitation and hygiene.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structure chart of the utility model two-stage type water saving device of toilet bowl;

Fig. 2 is among embodiment of the utility model, and the attachment of second flushing control apparatus places schematic diagram in the first flushing control apparatus through hole.

Describe the embodiment of the utility model two-stage type water saving device of toilet bowl in detail below in conjunction with accompanying drawing.

Manufacture and design a kind of two-stage type water saving device of toilet bowl, comprise water tank 1, loam cake 2, water-storage controller 3 and contain first trigger mechanism 41 and first flushing control apparatus 4 of first attachment 42, bath road import 44, bath road access cover 43 and overflow pipe 6, also the second bath road import 54 and the second bath road access cover 53 are set at the overflow pipe waist, and second flushing control apparatus 5 is set, it contains second trigger mechanism 51 that available clasp makes, and reaches second attachment 52 that available cotton rope makes; Like this, trigger second flushing control apparatus in water requirement more after a little while and promptly spur clasp 51 and cotton rope 52, open the second bath road access cover 53, only need the water of half to dash toilet, water saving significantly; And water requirement triggers first flushing control apparatus 41 more for a long time, drives cotton rope 42 and opens the first bath road access cover 43, also can guarantee sanitation and hygiene.

In the described two-stage type water saving device of toilet bowl, also a through hole 41A can be set,, be located at the top of first flushing control apparatus 4 described second trigger mechanism 51 clasp for example in the inside of first trigger mechanism 41; And with described second attachment 52 for example cotton rope pass the interior bone 41A of first trigger mechanism 41, guide the second bath road access cover 53 again into, make structure compact more.

In the described two-stage type water saving device of toilet bowl, the water surface M of second bath road import 53 control can not be too high or too low to the setting apart from MD of water tank bottom surface D, and general selection is the highest be advisable to 1/2 to 1/3 of water tank bottom surface D distance H D by drain surface H.

The utility model two-stage type water saving device of toilet bowl is with respect to the advantage of prior art: in control In the time of the single flush water yield, have less water volume control device, allow the user in the few feelings of required amount of flush water Choice for use under the condition can significantly reduce water, for family and social saving fund, cuts the waste, and is conducive to Valuable fwaater resources protection.
