CN2222189Y - Cistern with improved flushing device - Google Patents

Abstract

The utility model belongs to attachments on household sanitary equipment. In order to overcome the defects of the flushing device of the existing cistern such as easy ageing, corrosion and water leakage, the novel flushing device is proposed. The utility model comprises a cistern, a water level controlling valve and a flushing tube. The utility model is characterized in that an inverted u-shaped siphon tube, an elastic tube and a control arm lever which can depress the top of the siphon tube are additionally arranged in the cistern. The siphon tube, the elastic tube and the flushing tube are connected tightly. The siphon tube erects at original times, and is pressed under the water surface when the water needs flushing, and then water in the cistern can be drained out successfully. The utility model has the characteristics of no water leakage and no water overflow at original times. The utility model has the advantages of simple structure, convenient operation, reliable performance and low cost which are proved by the test operation of samples.

Description

Water tank with novel dewatering installation

The utility model belongs to the annex of domestic sanitary equipment, and it is specifically related to a kind of structure of novel dewatering installation.

The dewatering installation of family or unit lavatory inner water tank mostly is the structure of elastic hollow ball Movable valve at present, and it is aging because of other part, the structure corrosion is loosening is easy to cause the normal phase of valve bad sealing to leak, and forms a large amount of wastes of water.In addition, for other part of part of avoiding corrosion to have often uses copper material, so it also has defect of high cost.

The purpose of this utility model is to provide a kind of new structure, can solve the problem that former valve leaks because of bad sealing at all, and it also has characteristics simple in structure, that cost is low and the life-span is long.

By as above design, the water tank with novel dewatering installation that this programme provided includes water tank (1), have water inlet, the gutter below the water tank (3) of the altitude valve (2) that hollow water floats, it is characterized in that in water tank, also having syphon (4), elastic tube (5) and control arm (6), its syphon is an inverted U-shaped pipe, the sectional area of U-shaped pipe is 1.2～2 times of gutter sectional area, one end and elastic tube (5) and elastic tube all are tight the connections with the draining mouth of pipe in the water tank, another pipe end 90 degree elbow openings near the case bottom; Its control arm (6) be a rotating shaft vertically be articulated in casing, outside have handle, a crooked long-armed lever is arranged in the case, borehole jack on the termination of its lever and the syphon top on the extension board connects, and the plane of syphon U-shaped part is parallel with the direction of control arm rotating shaft part.

Elastic tube in this programme (5) is the light-wall pipe that a limber surface is pressed into helical corrugation.

Adopt this programme can embody following superiority: 1. the part in addition of water tank inside all can adopt nonmetallic moulding, and promptly corrosion fatigue life is long, and cost is also very low; 2. the water height in this water tank is to be controlled by the floating-type control valve, and draining is could realize when forming siphon by syphon, syphon is upright at ordinary times, peak level in the case is lower than the lower limb of siphon bend part, can not cause siphonage, therefore the water in the water tank must not flow out, and also can not leak; When 3. needing draining, siphonal top is depressed and when being lower than the water surface with the lever of control arm, water has been full of syphon, water in the water tank can successfully flow out, when the water surface was lower than siphonal free port, air entered stop draining in the pipe, and syphon is upright, do not set up siphon in the water injection process in the water tank, make that the control of draining is reliable; 4. when altitude valve broke down, when the water surface raise above the bend pipe lower edge gradually in the case, syphon can play overflow pipe, and the unlikely interior water of case that causes overflows ground in a large number; 5. its simple in structure being convenient to is promoted, and also realizes the transformation to old equipment easily.

Fig. 1 is the front section view of the water tank of the novel dewatering installation of this programme band.

Fig. 2 is the lateral view of Fig. 1.

Working state figure when Fig. 3 is draining.

The embodiment of this programme now is described with reference to the accompanying drawings.There is a hollow water to float the altitude valve (2) of formula in this water tank (1), generally water surface control is lower than the lower limb of siphon bend part, the syphon (4) that one inversion U-shaped is arranged in the case, a siphonal end tightly connects with elastic tube (5), effluent pipe mouth in elastic tube and the case tightly connects, syphon is upright at ordinary times, also has a control arm (6) on the water tank, it is a lever, mid portion and casing be hinged and outside to have handle, the termination point casing of its lever to be connected in the hole on the extension board of syphon top.

When needing draining, pull handle with hand, siphonal top is depressed, when the water in the water tank is discharged the air at syphon rear portion, water in the case successfully gutter under water tank (3) flows out, syphon sectional area ratio gutter big is for the ease of allowing water be full of soon in the syphon, making siphonage stable.Owing to be full of water fully in the pipe, siphonal weight strengthens, syphon will be automatically crooked along with the reduction of the water surface this moment, when the water surface is reduced to siphonal free port, one works as air enters pipe, and current are stop at once, is full of air again after the current in the syphon are clean, this moment, its proportion alleviated, and recovered upright under the elastic reaction of elastic tube again.The syphon free port becomes 90 degree elbow shapes, and its opening points to the direction that syphon is pressed, and can reduce the residual quantity of water in the water tank like this.It is not only water-tight at ordinary times, and it has the effect of overflow pipe when the altitude valve fault, also can not leak.

The pilot sample of this programme is through the operation proof, and it has simple in structure, easy behaviour Work, dependable performance, characteristics with low cost, it not only is convenient to promote the use of, and holds The old water tank of easy-to-use its transformation.

Claims (2)

1, a kind of water tank with novel dewatering installation, it comprises water tank (1), have water inlet, the gutter below the water tank (3) of the altitude valve (2) that hollow water floats, it is characterized in that in water tank, also having syphon (4), elastic tube (5) and control arm (6), its syphon is an inverted U-shaped pipe, the sectional area of U-shaped pipe is 1.2～2 times of gutter sectional area, one end and elastic tube (5) and elastic tube all are tight the connections with the draining mouth of pipe in the water tank, and another pipe end is being 90 degree elbow openings near the case bottom; Its control arm (6) be a rotating shaft vertically be articulated in casing, outside have handle, a crooked long-armed lever is arranged in the case, borehole jack on the termination of its lever and the syphon top on the extension board connects, and the plane of syphon U-shaped part is parallel with the direction of control arm rotating shaft part.
