Abstract

The utility model discloses a pressure cistern for a closet bowl, which comprises a sealing cistern body, and an air/water inlet device. The pressure cistern is characterized in that the air is stored when the water is stored, and a water drainage device of the utility model not only has the water drainage function but also is served as a gas chamber for gas. Due to the special performance of the system, the flushing strength of the water is enlarged under the double action of the compressed air pressure and the natural pressure of the water; the water consumption is decreased so that the water saving purpose is reached. Moreover, the structure is simple. The utility model is suitable for various types of closet bowls.

Description

The vapour-pressure type water tank

The utility model relates to a kind of vapour-pressure type water tank by air and water mutual effect, especially relates to the water tank that is used for the washroom closet.

At present, the water tank of existing washroom closet is to utilize the pressure reduction of water to finish flushing process, this just needs to store a certain amount of water and realizes washing purpose, tradition water tank once flushing water supply volume reaches 6 liters, and use sometimes and once can not thoroughly remove dirt, the long-term water supply volume of using is considerable, does not meet current water-saving requirement.

The purpose of this utility model is under the prerequisite that guarantees developing result, to reduce the water tank water supply volume, to greatest extent the conserve water resource.

The purpose of this utility model is to realize that by the vapour-pressure type water tank that a kind of following structure is provided this water tank comprises: seal case, air inlet water feed apparatus, vacuum valve, dewatering installation and water storage tank, and described air inlet water feed apparatus and intake tunnel fuse; Described air inlet water feed apparatus by the air-breathing valve seat of the hold-down nut of band pore, band pore and the center gas port is arranged and around the air-breathing spool of gas port constitute; Described vacuum valve is furnished with the nut of spring sealed bar and center band pore; Described dewatering installation is furnished with joint ring, spring and valve rod formation air chamber and is communicated with exhalant canal, and there is sealing ring the contact position of described exhalant canal and described joint ring.

Adopt the vapour-pressure type water tank of said structure to compare with the traditional water tank that adopts the drainage mode, the once flushing process can be saved 1/3rd water, the flushing great efforts, and developing result is good, and volume is little, can be installed in the water tank of all kinds closet.

Below in conjunction with accompanying drawing utility model is described in further detail.

Accompanying drawing shows the embodiment of vapour-pressure type water tank

Because the effect of water, when water flows through air inlet water feed apparatus [2] and enters water storage tank [16] through intake tunnel [3], air inlet water feed apparatus [2] is produced negative pressure, make air-breathing spool [6] shift out certain distance, thereby make the air centre bore and the pore all around of the pore by hold-down nut [4], the pore of air-breathing valve seat [5], air-breathing spool [6] successively, enter water storage tank [16] simultaneously with water.When the water yield reached predetermined value, water and air formed certain proportion in water storage tank [16], by the natural pressure of water, form compressed air in case, and when air pressure in the case was identical with hydraulic pressure, water inlet stopped automatically.Dewatering installation [10] is promptly controlled the break-make in water route, the air chamber [14] that serves as gas again, when dewatering installation is in closed condition, air pressure enters air chamber [14], overcome spring pressure and air chamber [14] inner seal ring [11] is depressed the exhalant canal mouth [15] that is blocked in water storage tank [16], when dewatering installation [10] when being in opening state, water enters closet flowing out rapidly exhalant canal mouth [15] through air chamber [14] in by joint ring [11] under the effect of Compressed Gas, dirt is discharged, the negative pressure that this process produces makes the spring sealed bar [8] on the vacuum valve [7] overcome spring pressure and removes nut [9] hole vacuum valve [7] is opened, flushing process finishes, spring sealed bar [8] nut [9] hole of rebounding, vacuum valve [7] is closed condition.

Claims

1, a kind of vapour-pressure type water tank, comprise: seal case [1], air inlet water feed apparatus [2], vacuum valve [7], dewatering installation [10] and water storage tank [16], it is characterized in that: described air inlet water feed apparatus [2] fuses with intake tunnel [3], have in the described air inlet water feed apparatus [2] in fixed valve base [5] can be with the pressure effect mobile air-breathing spool [6], described vacuum valve [7] opens or cuts out pore on the nut [9] by spring sealed bar [8] under suction function, the break-make that described dewatering installation [10] is promptly controlled the water route is served as the air chamber [14] of gas again.

2, water tank according to claim 1, it is characterized in that: there is gas port at air-breathing spool [6] center in the described air inlet water feed apparatus [2], gas port is arranged all around, hold-down nut [4] in the described air inlet water feed apparatus [2] has pore, and described air-breathing valve seat [5] has pore.

3, water tank as claimed in claim 1 or 2, its feature also is: air inlet water feed apparatus [2] is store air into water storage tank [16] simultaneously in water inlet.

4, water tank according to claim 1 is characterized in that: spring sealed bar [8] shutoff in the described vacuum valve [7] overcomes spring pressure during work and pore is opened on the pore of nut [9].

5, water tank according to claim 1 is characterized in that: constitute air chamber [14] by joint ring [11], spring [12] and valve rod [13] in the described dewatering installation [10], described joint ring [11] interconnects with spring [12] and valve rod [13].
