Abstract

The utility model relates to a piston type closet water tank, which comprises a shell body, a water inlet pipe, a water outlet pipe which are arranged at the bottom of the shell body, a water inlet valve and a water outlet valve. A piston body is arranged in the shell body along a cross section. The piston body and the inner wall of the shell body are sealed and matched. A spring is connected between the piston body and the shell body. The structure is adopted, flushing water pressure is high, and a small amount of water can have favorable flushing effect. The piston type closet water tank can save water, and the piston type closet water tank has simple structure. The piston type closet water tank is flexible and convenient to assemble and use. The utility model is an economical and environment protection flushing water tank.

Description

The piston type toilet seat water tank

The utility model relates to the structure of water closet with flushing tank.

Traditional water closet flushing tank, people are for improving flush efficiency, and outlet pipeline, the delivery port shape of the water tank that liquidates are emphatically improved, to improve the impulse force of water; Or the height of increase water tank, make the corresponding increase of liquid level in the water tank, by increasing the impulse force that liquid level difference improves water, but be limited by the shape size restriction of water closet, the design of water tank can not be too high excessive, therefore the water tank impulse force of conventional art is difficult to improve significantly, and the water tank internal construction is but done more complicated and more complicated on the contrary, gives maintenance, uses and bring great trouble.

The purpose of this utility model is the weak point that overcomes conventional art, and a kind of certain hydraulic pressure, assembling is flexible and convenient to use, developing result is good piston type toilet seat water tank of keeping all the time is provided.

The purpose of this utility model is achieved by the following technical solution: the piston type toilet seat water tank, include housing, be loaded on the water inlet pipe of housing bottom and outlet pipe, water intaking valve, outlet valve, along cross section piston body is housed in the housing, piston body and inner walls are sealed and matched, and are connected with spring between piston body and the housing.Further, housing is cylindrical, and the work plane of piston body is over against the water inlet and the delivery port of housing bottom, and spring is equipped with at the back side of piston body, and spring is connected between the case top and the piston body back side.And between water intaking valve and the housing water inlet flap valve is housed.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of water state into;

Fig. 3 is the structural representation of the state of discharging water.

Referring to Fig. 1-Fig. 3, present embodiment mainly is made of housing 1, water intaking valve 2, outlet valve 3, water inlet pipe 5, outlet pipe 4, flap valve 6, piston body 7, spring 8.Housing 1 is airtight cylinder, piston body 7 is housed in its cross section, piston body 7 is slidingly matched with housing 1 inner wall sealing, and the work plane of piston body 7 is connected with spring 8 over against the water inlet 11 and the delivery port 12 of housing 1 bottom between the back side of piston body 7 and housing 1 top.The course of work is such: close outlet valve 3, open water intaking valve 2, tap water enters in the housing 1 by water inlet pipe 5, flap valve 6, directly act on the work plane of piston body 1, hydraulic pressure makes on spring 8 compressions, the piston body 7 and moves, compression elasticity balance until hydraulic pressure and spring 8, flap valve 6 cuts out, and stops into water, the water of about 0.2MPa that keep-ups pressure in the housing 1 this moment.When needs wash, open outlet valve 3, the water in the housing 1 is discharged from delivery port 12 rapidly under the pressure of spring 8, piston body 7, the pressure when hydraulic pressure remains water into, about 0.2MPa, the water in housing 1 clears fully.

Such structure has obvious advantage:

1, utilize spring, piston body to keep the interior hydraulic pressure of housing, the impulse force of water is big, flushing Effective;

2, simple in structure, do not consume the energy;

3, housing can place vertically, traverse, inversion, all do not influence result of use, install and use flexible;

4, a spot of water just can produce good developing result, can save a large amount of waters, economic environmental protection.

Claims

1, piston type toilet seat water tank, include housing, be loaded on the water inlet pipe of housing bottom and outlet pipe, water intaking valve, outlet valve, it is characterized in that: along cross section piston body is housed in the housing, piston body and inner walls are sealed and matched, and are connected with spring between piston body and the housing.

2, water tank according to claim 1 is characterized in that housing is cylindrical, and the work plane of piston body is over against the water inlet and the delivery port of housing bottom, and spring is equipped with at the back side of piston body, and spring is connected between the case top and the piston body back side.

3, water tank according to claim 1 is characterized in that between water intaking valve and the housing water inlet flap valve being housed.
