Abstract

The utility model relates to an automatic flushing water tank for public places, such as a school, a showplace, a collective dormitory, a station, etc. The utility model is composed of a main water tank 1, an assistant water tank 4, a water absorbing pipe 2, a water overflowing pipe 3, a nut 3, a copper gasket 6, a rubber gasket 7, a screw rod 8 and a float ball 9. The water tank can optionally adjust the flushing time and can prevent the phenomena that the siphon does not stop, the water tank can not be stored with the water all the time and does not gnerate the siphon, the overflow does not stop; so that the utility model can reach the water saving purpose. The utility model has the characteristics of simple structure, convenient installation, reliable work, etc.

Description

Controllable automatic flushing water tank

The utility model relates to a kind of controllable type automatic flushing cistern that is used for public places such as school, cinema, dormitory, station.

At present, generally adopt siphon water tank to wash the just usefulness of groove in the lavatory of public place.Since design and structural problem, existing siphon water tank exist siphon incessantly, the case internal memory do not live water and not siphon, the more than phenomenon of overflow, causes the waste of water resource.

Task of the present utility model is to provide a kind of controllable type automatic flushing cistern, and this kind water tank can arbitrarily be adjusted washing time, overcomes above-mentioned defective, effectively using water wisely.

The utility model is achieved in that it is made up of main water box 1, suction water pipe 2, overflow pipe 3, auxiliary water tank 4, nut 5, copper pad 6, rubber sheet gasket 7, screw rod 8 and ball float 9.Its architectural feature is: the main water box 1 top auxiliary water tank 4 that has been welded; The overflow pipe 3 that two water tanks were connected about auxiliary water tank bottom surface one face down bonding was equipped with and makes is equipped with screw rod 8 and ball float 9 in the circular hole of opposite side (water supplement port), the top is equipped with nut 5, copper pad 6 and rubber sheet gasket 7 successively; A face down bonding is equipped with the suction water pipe 2 of an end outside case is stretched out in the bottom in the main water box 1.During installation, the suction water pipe lower end is connected with cleaning hose.In this water tank use, when drawdown in the main water box during to the siphon port of suction water pipe, the osculum that air promptly has from siphon port (air inlet break suction inlet) pours, and plays and destroys siphon (the disconnected suction) effect, thereby prevent that water tank siphon is more than, deposit the incessantly phenomenon of water.When water level in the main water box rises to the cleaning hose overflow, ball float rises water supplement port is opened, and auxiliary water tank is supplementing water in main water box immediately, and the interior water level of case is risen rapidly, thereby the generation siphon, thereby prevent, the cleaning hose overflow too small phenomenon of not siphon incessantly because of the water tank water intake amount.

The utility model is simple in structure, and is easy for installation, reliable operation, and this kind water tank can arbitrarily be adjusted washing time, prevents that siphon is more than, the case internal memory does not live water and not siphon, the more than phenomenon of overflow, reaches the water saving purpose, is suitable for wide popularization and application.

Fig. 1 is a configuration diagram of the present utility model.

Fig. 2 be among Fig. 1 auxiliary water tank 4 bottom surface water supplement port C to partial enlarged view.

Fig. 3 is the B-B sectional drawing of Fig. 1.

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

Main water box 1, auxiliary water tank 4 are all cuboid in the utility model, adopt 3mm steel plate weldering system to form, and auxiliary water tank 4 bottom surfaces one side has the circular hole for the overflow pipe 3 that is welded, and opposite side is made the water supplement port (seeing accompanying drawing 2) of band " ten " font rib.Suction water pipe 2 calibers are 40mm, are formed by 2 straight lengths and 6 90 ° of punched bends weldering systems, and the front, water sucking mouth has the disconnected osculum of inhaling of air inlet of a high 10mm, wide 15mm in the case.Overflow pipe 3 is the coating steel pipe of 20mm for diameter.Ball float 9 diameter 100mm, material is copper or plastics.

Claims

1, a kind of controllable type automatic flushing cistern of public lavatory use, form by main water box 1, auxiliary water tank 4, suction water pipe 2, overflow pipe 3, nut 5, screw rod 8, copper pad 6, rubber sheet gasket 7 and ball float 9, it is characterized in that: the main water box 1 top auxiliary water tank 4 that has been welded; Auxiliary water tank 4 bottom surfaces one face down bonding is equipped with overflow pipe 3, and screw rod 8 and ball float 9 are housed in the opposite side circular hole (water supplement port), and the top is equipped with nut 5, copper pad 6 and rubber sheet gasket 7 successively; A face down bonding is equipped with the suction water pipe 2 of an end outside case is stretched out in the bottom in the main water box 1.

2, controllable type automatic flushing cistern according to claim 1 is characterized in that, suction water pipe 2 is formed by 2 straight lengths and 6 90 ° of punched bends weldering systems, and the front, water sucking mouth has the disconnected osculum of inhaling of air inlet of a high 10mm, wide 15mm.
