Description

A kind of free quantitative flushing water-saving device

The utility model relates to the flushing water-saving device between town dweller's domestic sanitary, is mounted in a kind of on water closet or the pan more specifically and stores up the flush the toilet water saving fixtures of the water yield of daily life sewage and free difference.

At present, water closet and pan are by the predetermined water yield of flushing the toilet of storage tank, defecate, little, just all can't control the different middle lavatory water yields as required.The closet that also has adopts hand switches such as Wrench-type, and not only operation is wasted time and energy, and often owing to lose control of the water yield or switch is not closed completely, causes the bigger waste of water.Manufacturing and the installation requirement strictness of existing storage tank delivery port capping, the long-term use easily damaged, and causes the running water phenomenon.In addition, existing daily life sewage reclaims water saving fixtures, because one-time investment is more, engineered difficulty is bigger, thereby often is difficult for being accepted by the masses, and particularly to the transformation of existing dwelling house water closet and pan, it is very big to promote difficulty.

The purpose of this utility model is, solve weak point of the prior art, a kind of flushing water-saving device of storing up daily life sewage and can selecting different water supply volumes as required is provided, flush the toilet in particular for water closet and the pan of transforming existing dwelling house, a kind of water saving fixtures simple, with low cost, easy to operate, that water-saving performance is strong of installing are provided.

The utility model is realized by following measure: the storage tank height that suitably reduces existing water closet, or add a storage tank in the pan back, then, utilization water is by the characteristic of height to low gravity flow, with flexible pipe or hard tube washbowl bottom discharge mouth is connected with storage tank, water inlet pipe mouth in the storage tank is lower than the outfall of wash basin bottom, forms inverted-siphon.For lavatory water in guaranteeing is in time sufficient, the storage tank volume is enlarged 2 to 3 times, wherein, water storage tank for water closet is mainly expanded as suitable to both sides, and the pan storage tank can enlarge flexibly according to the interior space.The time switch of flushing the toilet is set on storage tank, and it mainly contains knob, brake bar, drive link, spring leaf, lifting rope, delivery port capping composition, and the weight of delivery port capping will be able to fall after rise naturally in water.The difference that needs according to stool, the urinal during use water yield of flushing the toilet, knob is threaded to the precalculated position, by drive link, the capping of lifting rope pull-up delivery port, then, by the frictional resistance of brake bar and some submissile reeds, the falling speed of control storage tank delivery port capping.

Below in conjunction with drawings and Examples the utility model is elaborated.

Accompanying drawing 1 is the sectional view of bowing of the present utility model;

Accompanying drawing 2 is sectional views of the present utility model;

Accompanying drawing 3 is flush the toilet internal construction schematic diagrames of time switch of the utility model;

Accompanying drawing 4 is flush the toilet schematic appearance of time switch of the utility model;

Accompanying drawing 5 is that the utility model is installed in the schematic diagram on the water closet;

Accompanying drawing 6 is that the utility model is installed in the schematic diagram on the pan.

The utility model mainly is made up of the time switch 1 of flushing the toilet, storage tank 2, delivery port capping 3, overflow pipe 4, tube connector 16.The time switch 1 of flushing the toilet is installed in the top of storage tank 2, and a little higher than overflow pipe 4 is to prevent by leaking outside case here.Time switch 1 inside of flushing the toilet is equipped with a brake bar 5, some submissile reeds 7 are housed on the heavy wall of circular housing 6, in the circle that through brake bar 5 tops of its length constitute when rotating, form contact friction with brake bar 5, spring leaf 7 is stressed when crooked, its stressed end can contact a little with another upright spring leaf, to constitute continual frictional resistance.Storage tank 2 inside are provided with a drive link 8, be connected and fixed by eyelet on the storage tank 2 and brake bar 5, be that a lifting rope 9 is arranged on the drive link 8, the lifting rope circle 10 that passes on the overflow pipe 4 is connected with delivery port capping 3, delivery port capping 3 is down truncated cone and is buckled on the delivery port, its weight will be able to fall after rise naturally in water, to strengthen sealing and lifting rope 9 is formed pulling force.During use, the difference that needs according to stool, the urinal water yield of flushing the toilet is threaded to the precalculated position with knob 11, and by drive link 8, lifting rope 9, the delivery port capping 3 of slinging, then, by the frictional resistance of spring leaf 7 with brake bar 5, the falling speed of control delivery port capping 3.When the utility model was installed on the water closet 12, the height of storage tank 2 will suitably be reduced to the wash basin outfall below 13, or a little more than wash basin outfall 13, but the water inlet pipe mouth 14 of storage tank 2 must be lower than wash basin outfall 13, so that form inverted-siphon.When the utility model was installed on the pan 15, the height choice of storage tank 2 was bigger, can determine as required.For guaranteeing that flushing supply is in time sufficient, the volume of storage tank 2 will enlarge 2 to 3 times, and wherein, water storage tank for water closet is mainly expanded as suitable to both sides, and the pan storage tank can enlarge flexibly according to the interior space.The tube connector 16 of wash basin outfall 13 and storage tank water inlet pipe mouth 14 all can with flexible pipe or hard tube.

The utility model compared with prior art, its major advantage is: (1) water-saving performance is strong. Not only can store up in a large number sanitary wastewater, but also Can control as required different water consumptions. (2) be easy to transform, install Simply. (3) reduced the link of leaking. Owing to omitted drain member of face washing basin Bend pipe and sewer have omitted a whole set of inlet channel of storage tank and parts, add The big weight of storage tank delivery port capping, thereby, integral sealing strengthened The property, can effectively prevent the generation of storage tank running water phenomenon. (4) joint About material reduces cost. Particularly omitted the ball valve of swimming in the storage tank Reach many water inlets, drainage pipeline, production cost and mounting cost are fallen greatly Low. (5) durable in use, reduced the maintenance trouble. Therefore, this practicality Novelly be widely used in changing of urban household and opened type manure pit, rural area Make, be specially adapted to the transformation of existing dwelling house toilet seat and squatting pan.
