Description

Pipe seal type water-saving closet

Technical field

The utility model design is a kind of to be controlled bedpan bottom flexible pipe and forms the pipe seal type water-saving closet that trap reaches sealing effectiveness.

Background technology

The shortage of water resources of China is long-standing.On history, China is that frequent country takes place arid, have saying of " hitting by drought 9 years out of 10 ".In the historical document record in more than 2200 years, big drought takes place just reach 1300 times more than.China water resource occupancy volume per person has only about 2300 cubic metres, be about the world per capita the water yield 1/4th.China's water resource not only occupancy volume per person is few, and distribution of water resources is extremely inhomogeneous, and the water system drainage area accounts for 63.5% of area to the north of the Changjiang river, and water resource but accounts for 19% of the whole nation.Along with Chinese society and expanding economy, the breach of water is also increasing.

Now, all started a water-saving climax throughout the country.With regard to the problem of toilet water saving, 3 liters, 6 liters water-saving toilet is peddled very fashionablely on the market.Can really go deep into market and conscientiously investigate, these water-saving toilets are not that to fall short of the reality be exactly that technology does not pass a test, and price is also very expensive.In order to solve the problem of water saving of toilet conscientiously, we might as well analyze from the operating principle of " U " type trap.Each closet is not under bedpan or at following water interface " U " type trap to be installed all.Its effect is the foul smell of isolating sewer, but the seed of trouble that it is wasted water when but to be us use closet, the problem of this " U " type trap is: the water of tap water or toilet is flushed to after the bedpan, must flow into sewer through " U " type trap, and " U " type trap several times changes the direction of current, and the impulse force of current does not almost have.More rigid foul (as doing stool) reentered sewer after can only leaning on a large amount of water that flow and forming siphonage after " U " type trap floats " U " type bossing.Both made be very easily with the molten urine of water because " U " type trap has remained water, it is also impossible to want to use a spot of water just the addle in " U " type trap to be replaced, non-with behind big flood, the long water formation siphonage.If do an experiment, a cigarette end is lost in bedpan, does not have one case water (more than at least 6 liters) not want it is washed away.So the shortcoming of " U " type of summary trap is: it is not all right that hydraulic pressure is little, and it is not all right that water pipe is thin, and the water yield has been lacked not all right.Moreover most closets all are the seat formula closets of the band water tank of installation in the city, and are convenient for ease of the flushing of going to toilet before we go to toilet at every turn, and once water is warm the bedpan pouring to need subpunch.And this dashes one case water of non-using up, and the water yield is uncontrollable.As for water tank often leak and the trouble of keeping in repair just let alone.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of control bedpan lower tube and form the pipe seal type water-saving closet that trap reaches sealing effectiveness that adopts is provided.Be to cause wasting water in a large number because fixing " U " type trap is arranged existing toilet, pipe seal type water-saving closet does not have fixing trap, thereby makes the problem of wasting water obtain basic solution.

Above-mentioned technical problem of the present utility model is by providing a kind of closet with following structure to solve, and this closet comprises: toilet body, bedpan, inner bag, flexible pipe, chain, spring, driven gear, driving gear, foot rest, water control line, snap switch, water tank.The driving gear that foot rest links to each other is owing to be subjected to the effect of spring tension, through initiatively, the transmission of driven gear, make flexible pipe place up state (see figure 2) for a long time, reach the effect of sealing bedpan outlet.After people used the lavatory, the foot rest that presses down with the foot down changed through gear drive and to be subjected to force direction, made the flexible pipe afterbody be in down situation (see figure 1), had realized the unimpeded of bedpan and sewer pipe interface this moment, used the smelly water ten minutes of foul to flow into sewer pipe smoothly.Also opened by water control line (or water valve) switch of foot rest control thereupon.Finish when seeing the bedpan flushing, unclamp foot rest, the strength of spring makes flexible pipe place afterbody situation up again through the gear drive meeting, and the water that is deposited in the flexible rubber hose plays sealing function again, and simultaneously, water valve also returns to the situation of cutting out.

Pipe seal type water-saving closet of the present utility model is compared with the closet of prior art has following advantage: the toilet stool washing of original " U " type trap must mix foul and smelly water with a large amount of water could form siphonage after reaching high water level, must use a large amount of water so clean bedpan.If employing the utility model---pipe seal type water-saving closet, " U " type trap of closet bottom is the way by flexible pipe that can state of a control, people depress foot rest when using the lavatory, just make formed between the bedpan and the following mouth of a river direct unimpeded, foul, when sewage is gone out bedpan without any resistance.After the foul in the bedpan was almost completely gone out bedpan, at this moment the water of water tank just began to wash this empty fully bedpan.The sequencing process of this flushing just and have the process of " U " type trap different fully.And pipe seal type water-saving closet is with the approaching clean empty basin of a spot of water flushing, and the process of this priority and the mode of drainage are exactly key point of the present utility model.Through test, once as long as urine is 1 liter water in flushing, and as long as the flushing stool is also water more than 2 liters, and the standard of China's standing order is 3 liters in urine, defecates 6 liters, does not just have a water tank still more on the market less than 8 liters of waters at all.Before if people go to toilet, for the convenience of cleaning, before using the lavatory, bedpan must be drenched, this also needs one case water.And pipe seal type water-saving closet is equipped with the button that moment discharges water in tank top, only just can drench toilet with half premium on currency.Calculate that thus pipe seal type water-saving closet is saved more than 70% at least than existing closet water, has realized water-saving purpose greatly.
