Abstract
The utility model relates to a flushing device designed for toilets. The drain valve unit of the utility model comprises two groups of drain valves with different water displacements, and each drain valve is controlled by a trip-switch respectively. Different drain valves with different displacements can be selected to meet the water demands of stool and urine flushing, so that water can be saved efficiently. The utility model is particularly applicable to the regions suffering water shortage.
Description
Technical field
The utility model relates to the flushing device that uses in a kind of washroom.
Background technology
At present, be used for wc flushing cistern in the washroom, all only establish one group of drain valve assembly sitting posture or squatting pan, regardless of different kinds of after an action of the bowels, all to wash with whole box water.This class flushing device relatively is suitable for big flushing after an action of the bowels, and washes with whole box water after urine, is undoubtedly a kind of waste to water resource.For using water wisely, also have and adopt valve of double gear switch control, control what of water yield with the length of valve opening time.This structure more complicated, maintenance cost is also high, and is difficult to be used for the gear switch in original water tank, a kind of valve of displacement are transformed.
Summary of the invention
The purpose of this utility model provides a kind of effectively drain valve assembly of water-saving water-saving wc flushing cistern.
The drain valve assembly of the water-saving water tank that the utility model provides is made up of the drain valve assembly of two groups of different displacement, and is controlled by operating switch separately respectively.
The drain valve assembly of the water-saving water tank that the utility model provides, the drain valve assembly of two groups of different displacement is divided into drain valve assembly and last drain valve assembly down, last drain valve assembly is located at down on the bleed off pipe of drain valve assembly, and the delivery port of last drain valve assembly is communicated with bleed off pipe.
The drain valve assembly of the water-saving water tank that the utility model provides, the drain valve assembly of two groups of different displacement is divided into drain valve assembly and last drain valve assembly down, bleed off pipe directly is communicated with the outfall of water tank, following drain valve assembly and last drain valve assembly are located at respectively on the bleed off pipe, and their delivery port is communicated with bleed off pipe respectively.
The utility model has been owing to adopted said structure, therefore, after excrements, can select the drain valve assembly of different displacement for use, thereby reach water-saving effectively purpose according to what of required water amount.In addition, because the shared cleaning hose of its double valve, can transform the water tank of a gear switch of the prior art, a kind of displacement easily, make its become double valve, have two gear switch to control the water-saving water tank of big or small water yield flushing closet
Description of drawings
Fig. 1, Fig. 2 are respectively the schematic diagram of the embodiment of the different drain valve assembly of two structures of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Embodiment one: referring to Fig. 1, the drain valve assembly of the water-saving water tank that present embodiment is described is made up of the drain valve assembly of two groups of different displacement.Following drain valve assembly 4 is identical with drain valve assembly of the prior art, and last drain valve assembly is located at down on the bleed off pipe 2 of drain valve assembly, and its delivery port is communicated with bleed off pipe 2.Like this, bleed off pipe had both played the effect of overflow, became the gutter of the higher last drain valve assembly of relative position again.Upper and lower drain valve assembly is controlled by operating switch 6,7 separately respectively.When the needs big yield, operating switch 7 is then opened down the valve of drain valve assembly; When the little water yield of needs, operating switch 6 is then opened the valve of drain valve assembly, and the water of the little water yield is by bleed off pipe 2, flows out the flushing closets through the delivery port 5 of water tank 1.
Embodiment two: referring to Fig. 2, the drain valve assembly of the water-saving water tank that the utility model provides, bleed off pipe 2 directly is communicated with the outfall 5 of water tank 1, and following drain valve assembly 4 and last drain valve assembly 3 are located at respectively on the bleed off pipe 2, and their delivery port is communicated with bleed off pipe 2 respectively.Bleed off pipe not only plays the effect of overflow, and becomes the common gutter of upper and lower drain valve assembly.Compare with embodiment one, more compact on the structure.Its operating principle is identical with embodiment one, repeats no more.
Claims (3)
