Abstract

The utility model relates to a water quantity controllable water flushing water tank of a closet, which provides a water flushing water tank of a closet which discharge different water quantity according to different requirements. The water quantity controllable water flushing water tank of a closet is characterized in that Two water discharge switches (1) and (9), and two water discharge openings (4) and (6) of which water level difference is 3-25 cm are arranged on a water storage tank. The purposes that pee or sputum is flushed by small water quantity, and stool is flushed by large water quantity are achieved through controlling different water discharge switches. When the water quantity controllable water flushing water tank of a closet is used, as long as the positions of the water discharge switches for controlling large and small water quantity are marked outside a water flushing water tank of a closet, and the functions can be realized.

Description

Water yield controllable type closet flushing water tank

The utility model is two different drainage switches of a kind of use, selects to discharge the closet flushing water tank of water yield size.

The drainage switch and the outfall of existing closet flushing water tank only have one, and outfall is in the bottom of water tank.So no matter wash urine when still defecating each displacement all identical.And in fact can be with less water when flushing urine or sputum, just need be with more water when flushing is defecated.So, use existing closet flushing water tank then to waste great amount of water resources.

The purpose of this utility model provides a kind of flushing urine, uses the little water yield during sputum, uses big yield during the flushing stool, with water-saving water yield controllable type closet flushing water tank.

The purpose of this utility model is achieved in that and is provided with two drainage switches (seeing Figure of description) [1], [9] and two outfall [4], [6] that water-head is 3～25cm on cistern, as Fig. 1 (is the water tank sectional drawing, [5] be tank shell, [10] are the water inlet control water level).Outfall [6] is at water tank bottom, and outfall [4] is the high position of 3～25cm in distance outfall [6].Two outfall link to each other with L type pipe and lead directly to toilet.Flushing urine, sputum or when needing the little water yield is opened seal cover [3] (being drawn back by drawing chain [2]) by switch [1], discharges H through delivery port [4] ₁The little water yield of section, as Fig. 2, this moment is because H ₁The hydraulic pressure of section is less than (H ₂-H ₁) section hydraulic pressure, so can not being turned one's coat to press, do not open seal cover [7].When washing stool or needing big yield, open seal cover [7] (drawing back), discharge H2 section big yield through delivery port [6], as Fig. 3 by drawing chain [8] by switch [9].As long as outside flushing tank, identify the position of the switch of the big or small water yield of control,, use the little water yield during sputum in use, use the purpose of big yield during the flushing stool with regard to realizing flushing urine.The water inlet portion structure of this closet flushing water tank is identical with the conventional toilet cistern, so this improvement has only increased a little cost, but can save great amount of water resources.
