Abstract

The utility model relates to a lavatory pan used water saving type air flushing device, and is mainly composed of a blower (1), an airtight cover board (2), a lavatory pan (4) and an air supply channel (5). The working principle is as follows: the airtight cover board (2) covers the lavatory pan (4), thereby an airtight space is formed inside the lavatory pan (4), the upward side of the airtight space is provided with air supply channel (5), the other end of the air supply channel is provided with the blower (1), when the lavatory pan (4) needs to be flushed, the blower (1) starts to supply air to the lavatory pan (4), so as to form a certain air pressure in the airtight space, the air pressure forces the air to pass the U trap (6) of the lavatory pan (4) to flow into the sewer from the drain, the dirt in the lavatory pan (4) can also be sent into the sewer with the air together. The utility model is applicable for various sitting and squatting toilet pan, the flush process each time is around 3 seconds, the water consumption is less than 1 liter, when water supply is stopped, and the utility model can also be used.

Description

Water-saving air douche device

The present invention relates to the flusher of a kind of washroom lavatory pan.

Have pass department and introduce, in the daily life, the waste of water mainly contains two aspects: the one, and radiator leak; The 2nd, in the lavatory pan flushing process, most of water (account for daily life water supply volume 1/3rd) is wasted.Therefore, solve the problem that lavatory pan flushing water consumption is big and leak, become a long-term puzzlement people's a difficult problem.In order to prevent radiator leak and using water wisely, the invention of many kinds of water saving fixtures and the anti-accessory that leaks has been arranged at present.But, all there are two common weakness in all inventions: the one, and water flushing, water consumption is big (removes that minority costs an arm and a leg, baroque lavatory pan, outside about 5 liters of the water consumption of each flushing, most lavatory pans, the water consumption of each flushing is still more than 5 liters); The 2nd, the radiator leak problem is not solved yet fully.Find by retrieval, adopt the ventilator air-supply, see the invention of dirt in the lavatory pan off, yet there are no by air.

Along with The development in society and economy and Increase of population, water resource can be more and more valuable, and the water of advocating thriftiness has become our common recognition.Purpose of the present invention just provides a kind of air douche of using, leakproof, remarkable, simple in structure, the enforcement convenience of water-saving result, and various the water-saving air douche devices that formula, crouching type closet bowl can be installed and used.

Solution of the present invention is, remove original wc flushing cistern of lavatory pan or rinse water valve, using a seal cover board instead lives the lavatory pan flap, make and form sealed space in the lavatory pan, the top of sealed space is provided with air-supply passage, the air-supply passage other end is equipped with ventilator, when lavatory pan need wash, in lavatory pan, blow by air-supply passage by ventilator, thereby in sealed space, form certain air pressure, air pressure forces the trap of air through lavatory pan, flows to sewer from sewage draining exit, and the dirt in the lavatory pan is also along with air is together sent into sewer.

Because the present invention adopts air that dirt is sent into sewer, therefore can utilize daily life sewage (as the water of washing one's hands, vegetable washing water) flushing to stick in the dirt on the lavatory pan inwall, need only in lavatory pan, spill the daily life sewage about 0.5 liter during each the flushing, no longer waste precious water resource, even feed pipe is cut off the water, still can wash, be fit to very much the serious place of lack of water and use.

For easy to use, the present invention can also supply a spot of water by the water inlet of lavatory pan in lavatory pan, i.e. the dirt that flushing sticks on the lavatory pan inwall can form water seal again again.

The present invention's process test of many times and actual the use prove the each water consumption of washing of water-saving air douche device less than 1 liter, leakproof, and water-saving result is very obvious.

Accompanying drawing is the generalized section of water-saving air douche device embodiment.

Below in conjunction with accompanying drawing embodiment is further explained:

As shown in drawings, the water-saving air douche device of forming by ventilator (1), seal cover board (2), lavatory pan (4), air-supply passage (5), electromagnetism water valve (7), noise enclosure (3) and power switch (8).Its operating principle is: seal cover board (2) is lived lavatory pan (4) flap, start ventilator (1) and electromagnetism water valve (7) then, water inlet by lavatory pan (4) is blown and water in lavatory pan (4), under the mixing flushing action of empty G﹠W, stick in dirt on the inwall and other dirt, locate to flow into blow-off pipe through trap (6) together in company with air.

Present embodiment is installed in ventilator (1) the water inlet top of lavatory pan (4), utilize the original intake tunnel of lavatory pan (4) as air-supply passage (5), can allow lavatory pan (4) more succinctly attractive in appearance like this, go up installation and use also convenient at various lavatory pans (4).

Power switch (8) is by power line (9) control ventilator (1) and electromagnetism water valve (7); Present embodiment go up to be installed power switch (8) at seal cover board (2), utilizes the pressure of shift knob to prevent that seal cover board (2) from being raised by air.

The effect of noise enclosure (3) is to reduce noise and have safe, attractive in appearance effect; The simpler of seal cover board (2) mainly contains two kinds, and a kind of method is to install the encapsulant that prevents that air-flow from escaping on the original cover plate of lavatory pan (4) (and seat ring) additional; Another kind method is the size according to lavatory pan (4) bore, makes one and can cover lavatory pan (4) (crouching type closet bowl that does not have cover plate and seat ring) mouth, the cover plate that barrier air is escaped from lavatory pan (4) top.

The employed ventilator of present embodiment (1) is a centrifugal blower, as long as flow and blast are suitable, also can adopt the blower fan of other types.Ventilator (1) also can be installed in lavatory pan (4) in addition Anywhere (as on the wall of washroom or outdoor), introduce by airduct then.]

The each flushing process of present embodiment is about 3 seconds, and the time is short, water-tight, water-saving result is remarkable.

Another kind of embodiment of the present invention mainly is made up of ventilator (1), seal cover board (2), lavatory pan (4), air-supply passage (5), noise enclosure (3), cancellation electromagnetism water valve (7) and water pipe.Its operating principle is: when lavatory pan (4) needed flushing, seal cover board (2) was lived lavatory pan (4) flap, starts ventilator (1) then and blows in lavatory pan (4), makes dirt locate to flow into blow-off pipe through trap (6) together in company with air.After closing ventilator (1), utilize the inwall of daily life sewage (as the water of washing one's hands, vegetable washing water) flushing lavatory pan (4), and locate to form again water seal at trap (6).

The advantage of present embodiment is simple in structure, does not waste precious water resource, still can wash when feed pipe is cut off the water, and is fit to very much the serious place of lack of water and uses.

The invention process is convenient, can be applied to various seat formulas and crouching type closet bowl, promotes the use of to have obvious social and economic benefit.
