Abstract

The utility model relates to a toilet cistern matched with a sitting type toilet and a squatting type toilet, which comprises a drainage and water supply mechanism, a regulation device for water quantity and water level and a toilet cistern housing. The toilet cistern is characterized in that an inverted U-shaped pipe and a steel body transmission mechanism are adopted to drain and supply water, and the water displacement and the height of the water level are regulated by a regulation pipe for the water displacement and a water limiting block, wherein, an inverted U-shaped siphon replaces a drain valve which is arranged on the bottom of the cistern, and the defects of the trickling water and the water seepage which are caused by that the drain valve of the conventional toilet cistern is arranged in the cistern and is difficult to close tightly are solved; the steel body transmission mechanism comprises a flushing button, a keg float, a water supply valve rod and a sealing ring. The utility model has the advantages of simple structure and convenient operation and maintenance, is difficult to damage, and replaces the conventional rope type transmission mechanism of which the operation is usually out of order and the parts are easy to damage. The utility model can save water and strength.

Description

Toilet cistern

The utility model relates to toilet and the supporting water tank of using of pan, particularly novel draining water intake mechanism and water yield water level control apparatus.

At present domestic and international popular tank for excrement pan, major part all is made up of several parts such as water intaking valve, draining valve, button or handle, rope drive mechanism and tank shells.Draining valve generally is installed in water tank bottom, each flushing the toilet after use all need press the button or draw handle, by lifting on the rope drive mechanism drive valve ball, to wash by water to urinal thereby open draining valve, the movement of falling object of bath Bi Liyong valve ball self gravitation makes drain shut valve; Meanwhile transmission mechanism is opened water intake valve, is water level when rising to setting height when water tank inner storing water amount reaches setting value, and water intaking valve is closed automatically.There are critical defect in the traditional water tank and the mode of operation thereof of this structure: 1. draining valve can only be installed in water tank bottom, and the drip infiltration seriously causes water resource waste because draining valve often fits badly; 2. the often malfunctioning and very easily damage of rope drive mechanism, frequent so maintenance capacity is big.More than two big shortcomings, no matter in dwelling house still is the lavatory of hotel or office building, can both see whenever and wherever possible, to the stage of facing the fearful with no fears.

In recent years, more domestic producers and unit are devoted to improve this cisten mechanism and component, and attempt overcomes above two big shortcomings, but it is little to take effect.For example, application number is 882136305 utility model, in its cisten mechanism and parts, though water intaking valve has been made significant improvement for water-leakaging not, complex structure and cost are higher; And still do not overcome draining valve and place often fitting badly and drip infiltration important disadvantages that water storage causes, and flush button need be exerted oneself big and the duration is longer.

The purpose of this utility model is: a kind of the have novel draining water intake mechanism and the tank for excrement pan of water yield water level control apparatus are provided, and it has not the drip infiltration, operation is not malfunctioning, not fragile, easy to use, cheap and economize on water advantage such as laborsaving.

Tank for excrement pan of the present utility model comprises draining water intake mechanism, water yield water level control apparatus and tank shell, it is characterized in that: adopt the draining of inverted U syphon, syphon upper elbow part is in when not draining on the water storage surface; Syphon one end communicates with urinal, and the other end links to each other with the displacement adjustable pipe.

The utility model adopts water inlet of steel body transmission mechanism control and draining, and this mechanism comprises flush button, keg float, water inlet valve rod and sealing ring.

The purpose of this utility model reaches like this: adopt syphon to replace traditional draining valve, make the on-off action that is installed in water tank bottom and is immersed in the traditional draining valve among the water storage change over the siphonal bent tube section that is placed on the water storage surface and play on-off action.When the siphonal bent tube section of inverted U stretches out in the water storage surface, be equivalent to draining valve and close tight; When pressing with flush button that keg float links to each other, keg float descends, and utilizes the piece control water storage surface lifting position of restricting water supply, and water storage is risen flooded the bend pipe top, is equivalent to draining valve and is opened fully, and urinal is promptly very promptly poured in draining.

The utility model adopts the draining of inverted U syphon to replace traditional draining valve draining, and the switch of draining is shifted out on the water storage among water storage, often fits badly the drip infiltration phenomenon that causes thereby thoroughly overcome traditional draining valve; The bath knob gentle slow-motion water of draining rapidly just of forming a steel body structure with keg float and water inlet valve rod is pressed in employing, replaces often traditional rope transmission mechanism of very easily damaging of malfunctioning and part of action.

The utility model adopts novel toilet closet water tank simple in structure to have fairly obvious advantage, not only overcome the infiltration of the frequent drip of traditional water tank and mechanism is malfunctioning and major defect such as part rapid wear, but also have with low cost, easy to use and economize on water advantage such as laborsaving.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is a tank for excrement pan structural representation of the present utility model, comprise water intaking valve 3,4 and 5, syphon 9, displacement adjustable pipe 6, the piece 10 of restricting water supply, bath knob 1, several parts such as keg float 2 and tank shell 11,12 are formed, adopt the draining of inverted U syphon, its upper elbow part is exposed when not draining on the water storage surface; Syphon one end links to each other with urinal; The other end links to each other with the displacement adjustable pipe; Syphon adopts pipe or rectangular tube, and interior cross-sectional area is 3-30cm ², with 10-30cm ²For good; The distance of displacement adjustable pipe lower end is dried up case bottom interior surface is 0.5-10cm, and the displacement adjustable range can reach the 8-15 liter; Adopt steel body transmission mechanism, form by several parts such as bath knob (or handle) 1, keg float 2, water inlet valve rod 3 and sealing rings 5; The restrict water supply lifting height of piece control water storage water level of employing, water storage water level rising when keg float descends, thus flooded inverted U syphon upper elbow top.Action principle is as follows: press bath knob (high level cistern to pan then pulls handle) with hand, also descend simultaneously with the bath keg float that fuses of knob and valve rod, the height that inlet valve is opened with the water storage water level rises.When water level rises to when flooding the siphonal bend pipe of inverted U top, syphon begins draining, and the water storage in the water tank is poured urinal rapidly at the utmost point in the short time, and bath is finished in the water tank only remaining bottom interior surface to the water storage between the displacement adjustable pipe lower end; Water intake velocity was slower after meanwhile inlet valve was opened, need could rise to setting height draining before to water level 15-30 time second approximately, utilize buoyancy of water to make the keg float come-up, make water valve rod into rise to the position of closing inlet valve tight and make height before the bath knob returns to draining, for draining next time performs all preparations.
