Abstract
A pneumatic flushing device for water closet is composed of the ring of seat-type water closet and cover body, which are linked to the seat-type water closet in movable mode. After they are closed, an air tight space is formed inside the water closet. An air compressing unit is installed to said cover body. Pressing the air compressing unit by hand can generate a pressure in said space to force the water and excrement to be drained out. Its advantages are saving water and high effect.
Description
The present invention relates to a kind of flushing device for water-closet, especially a kind of air pressure flushing device for water-closet that is used for the double as closestool cover of toilet seat closet.
The toilet seat closet extensively adopts waterpower to dash just mode at present.There is a certain amount of water in the toilet as water seal water (about the 20cm height), is used to seal sewer odours.Waterpower is dashed just, and process is: after excrements was sneaked into water seal water, water tank discharged water, and water tank water mixes with water seal water, U type water seal toilet side liquid level is higher than sewer side liquid level, water is discharged to the sewer side from the toilet side, and is high equal until U type water seal both sides liquid level, promptly remaining water seal water.So it is to realize the mobile discharge of water seal water by U type water seal both sides liquid level difference that waterpower is dashed.Its shortcoming is: reach higher water seal water flow velocity and carry just thing discharge, need to consume the bigger water yield; Still residual just thing on a small quantity in the water seal water that stays.
China utility model CN2172783Y discloses a kind of gas-water mixed type flushing cistern.After having adopted this water tank, dash just water speed height, and be dissolved with a large amount of air in the water, reduced flow resistance, have good scouring effect.But it is very suitable for crouching type closet bowl.For the toilet seat closet, excrements is directly sneaked into water seal water, does not exist just thing to the adhesive power of wall, and is less demanding to water velocity.Have only by improving the static pressure on the U type water seal toilet side liquid level, just can reach developing result preferably.
The purpose of this invention is to provide and a kind ofly come flushing device for water-closet, can not only economize on water, and dash just effective towards defecation by improving the air pressure on the water seal water liquid level in the toilet.
For achieving the above object, a kind of air pressure flushing device for water-closet that is used for the toilet seat closet of the present invention is made of toilet seat and toilet lid; On the toilet lid blowing plant is housed; Be flexible connection between toilet seat, toilet lid and the toilet, after toilet seat, toilet lid and toilet three cover, hermetic seal between toilet seat, toilet lid and the toilet three, the air outlet slit of the blowing plant on the toilet lid only communicate with air in the toilet.
The principle of air pressure flushing device for water-closet is to flow by the air pressure official post water seal water on increase toilet U type water seal two liquid levels to carry the excrements discharge.Strength is dashed just, and process is: excrements is with after water seal water mixes, and by upgrade block closet internal gas pressure p, toilet U type water seal water is rapidly by toilet side direction sewer side flow, when the air pressure recruitment
P is when the water seal water column is high in the toilet, and water seal water carries excrements and discharges, and boiled water tank injects new water seal water then.
Toilet seat and closestool cover are also arranged on the common toilet, but do not have hermetic seal and boost function.Closed back hermetic seal between toilet seat, toilet lid and the toilet three in air pressure flushing device for water-closet of the present invention can be by inlaying soft rubber with the closed contact site of toilet on the toilet seat, inlaying soft rubber with the closed contact site of toilet seat realize on the closestool cover body; On the closestool cover body, blowing plant is housed, can be by adopting an elastic bag body with certain air volume, hand changes its air volume size to be realized.After toilet seat, toilet lid and toilet three closure, because the air outlet slit of elastic bag body only communicates with air in the toilet, so just constituted an air sealing body of being made up of air in air in the toilet and the elastic bag body in the toilet, the total measurement (volume) of supposing seal is V
1, its air pressure p
1Be atmospheric pressure, be approximately 10000mm water column height.After the elastic bag body was following by hand, the aeroseal body bulk was reduced to V
2, air pressure rises to p
2This process conservatively is calculated as constant temperature process, then has
p
1／p
2=V
2／V

Know by this formula, if water seal water height h in the toilet
1Be 200mm, so water seal water discharged required pressure p
2Be 10200mm water column height, i.e. 10000/10200=V
2/ V
1, V then
2/ V
1=0.98, the air volume that the back can be reduced so the elastic bag body is depressed is not less than its 2% of preceding air volume and interior air volume summation of toilet that be depressed.Practical application can suitably strengthen the elastic bag body bulk.
As seen from the above analysis, the elastic bag body only changes 2% of total air volume in the toilet, can make to produce the 200mm water column pressure in the toilet on the liquid level, has been equivalent to inject in toilet the pressure of the high water generates of 200mm.Because toilet is infundibulate, the high water of injection 200mm is equivalent to two or three times of former water water shutoff (establish and also to be the 200mm height).So, adopting air pressure flushing device for water-closet of the present invention, the toilet water seal water that is mixed with excrements is discharged in pressurization earlier, the new water seal water that reinjects, it is economized on water at least more than two or three times.In addition, because the water seal water of retaining is a clear water, so it is effective towards defecation.
Below in conjunction with accompanying drawing the present invention is done concrete description.
Fig. 1 is the air pressure flushing device for water-closet structural representation that the present invention is used for the toilet seat closet.
Fig. 2 is that air pressure flushing device for water-closet that the present invention is used for the toilet seat closet is loaded on the schematic diagram on the toilet.
The air pressure flushing device for water-closet that is used for the toilet seat closet shown in Figure 1 is flexible connection by being made of toilet seat 3 and toilet lid 2 between toilet seat 3 and the toilet lid 2.On the closet lid 2 blowing plant is housed, blowing plant has adopted hand to change the elastic bag body 1 of air space size in this programme, constitute by hand pressure board 4, airtight elastic bag 5, during hand pressing plate 4, pneumatophore 1 shrinks, and air volume reduces in the air bag, and air is only from opening air outlet slit discharge on closestool cover, after unclamping hand, pneumatophore recovers.On toilet seat 3, be inlaid with soft rubber 7 with the closed contact site of toilet, on closestool cover body 2, be inlaid with soft rubber 6 with toilet seat 3 closed contacts site, make the air volume of closed back formation sealing in toilet between toilet seat, toilet lid and the toilet three, the size of this air volume changes with the change of air volume in the elastic bag body 1, thereby changes the pressure in the toilet.
The air pressure flushing device for water-closet that the present invention of being shown in Figure 2 is used for the toilet seat closet is loaded on the schematic diagram on the toilet, this device double as closestool cover.For flexibly connecting, cover hermetic seal between back toilet seat 3 and the toilet 8, hermetic seal between toilet lid 2 and the toilet seat 3 between air pressure flushing device for water-closet and the toilet 8.
