The flushing force is large. The noise is low. The flushing effect is obtained by the water of 6 kg. The utility model is also provided with a pressure limiting device. The maintenance and the easy are convenient. The utility model provides a replaceable product for saving the water resource.

Description

Water saving cistern

The utility model relates to a kind of water tank that sanitaryware use, cistern for toilet water-saving cistern of being used for.

Along with the use of increasing sanitaryware, water supply volume increases considerably and China's distribution of water resources is extremely uneven, and day is becoming tight, so the reasonable utilization of water resource has placed on the agenda.The research and development cistern for toilet water-saving cistern just has bigger economic benefit and social benefit.

The patent No. 92226304.3 " elastic force cistern for toilet water-saving cistern " is though can economize on water, and noise is low, can't solve the problem of leaking fully, and structure is reasonable not enough, also needs skeleton.

The purpose of this utility model is to provide a kind of cistern for toilet water-saving cistern of the property improved, and outside decapacitation water saving, noise were low, it was simple in structure, keeps in repair easy to usely, can increase the service life.

The utility model is achieved in that cistern for toilet water-saving cistern is by the elastic internal bladder that is fixed in housing, the bonnet, water intaking valve, water-in and water-out valve gear and handle are formed, on the wall by housing, cavity that bonnet forms the ripple muscle is arranged, be fixed with the outlet valve device in the cavity, and water intaking valve, inlet valve mechanism are fixed on outside the cavity.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Elastic internal bladder (5) is the top, and through hole is arranged at the bottom, and the closed cuboid cavity of two projectioies is arranged at the top.Make by corrosion-resistant, age inhibiting TR thin rubber material.

Housing (4) becomes the pentahedron cavity by ABS plastic or ceramic material, on the inside and outside surface of left and right, antetheca or the ripple muscle arranged on the external surface, left and right wall is located the male end of through hole near bonnet (22), interior fitting face is 45 ° of inclined-planes, for housing (4) and bonnet (22) more seals, the inner, inclined-plane have with left and right wall on the sealed muscle that mates of ripple muscle.Two elliptical apertures and a through hole are arranged at housing (4) top, and having on the edge has the extension of through hole to climb on one, and three through holes are arranged at the bottom.

Bonnet (22) is identical with housing (4) material, the top has has the extension of through hole to climb on three, on the inside and outside surface of bonnet (22) or have on the inner surface with housing (4) wall on identical ripple muscle, cooperating on the inner, inclined-plane also has the sealed muscle that matches with housing (4) the inner, inclined-plane.

Base plate (21), pressure limiting plate (3) are respectively the strip of through hole.

Valve gap (6), valve body (10) are two ends threaded T shape pipes, and pull bar (8) upper end is fixed with handle (1), and the lower end is fixed on the valve plug (12) of spring (11), and the end in addition of spring (11) is fixed in the valve gap (6).

The radiation fins that sealing shroud (9) is and elastic internal bladder (5) same material is made, valve plug (12) is close in the bottom, and openend is clamped between valve gap (6) and valve body (10), and screws to connect with cap (7) also and be integral the formation outlet valve.Base plate (21) is passed in the outlet valve lower end, housing (4) is fixed on the housing (4) with nut collar, and the upper end is passed elastic internal bladder (5) and is tightened on elastic internal bladder (5) with nut, and valve gap (6), housing (4) are passed in the upper end of pull bar (8), pressure limiting plate (3), screw (2) are connected with handle (1), and pressure limiting plate (3) has the screw (2) of through hole and handle (1) to fuse with middle, and screw (2) is spun on the pressure limiting plate (3), is the outlet valve device.

Lining (13) is the threaded T shape in lower end, tightly is embedded in housing (4) through hole, lower end, and valve pocket (15) is by making with elastic internal bladder (5) same material, and T-valve plug (14) is close to the bottom of valve pocket (15).

Valve casing (17) on the ball chamber of three vertical through hole is arranged, lower through-hole taps into water pipe (18), and last through hole embeds valve pocket (15), valve casing (17), valve pocket (15) be clamped in and cap (16), lining (13) between, and with and cap (16) screw connection formation water intaking valve in aggregates.

Water pipe (19) one termination valve casings (17), an end is connected with sparge pipe (20) by elbow, and the through hole that sparge pipe (20) passes on housing (4) and the base plate (21) is fixed on upward formation inlet valve mechanism of housing (4) with nut, packing ring.

Housing (4) is climbed with screw by the extension on it with bonnet (22) and is linked to be an integral body, hangs to climb to fix with two on the bonnet (22) and just can use on the wall.

During use, flushing water enters valve casing (17) from water inlet pipe (18), enter elastic internal bladder (5) by water pipe (19), sparge pipe (20), after water is many to around heave and be close to housing (4) ripple muscle all around, at this moment the valve pocket in the water intaking valve (15) is promoted valve plug (14) and makes it sagging by elastic internal bladder (5), withstand water inlet pipe (18), no longer water inlet.During bath with portable handle (1), connected valve plug (12), sealing shroud (9) move up, and just open the delivery port of valve body (10), and water is gone out the purpose that reaches flushing from delivery port, after openhanded, sealing shroud (9) returns to original position and closes delivery port under spring (11) effect.

If housing (4) internal pressure is too high, elastic internal bladder (5) is gone up the projection top pressure limiting plate (3) that will make progress, and at this moment pressure limiting plate (3) moves up will drive handle (1) thereby move up and opens outlet valve and water is run out play a protective role.

The utility model is compared with prior art: because adopting elastic internal bladder good as its seal degree of Water-storage bag, form waveform with the housing wall close contact, omitted skeleton, structure is simpler. Outside the gravity that dewaters during bath, the additional elastic force that produces when also having the elastic internal bladder compression, therefore scouring force is bigger, so water-saving, only need 6 kg of water, just can reach the same developing result of old-fashioned water tank, because being equipped with outlet valve, the water outlet of elastic internal bladder make the sealing property of delivery port better, thoroughly solve the drawback of leaking, then keep in repair the outside that now water intaking valve is installed in housing, renewal part is more convenient, can reduce the volume of original elastic internal bladder simultaneously, increase the elastic force of elastic internal bladder, and limited pressing plate, guarantee safety, and prolonged service life.
