Consult Figure 13 (a), Figure 31 (a), Figure 31 (b), under actual conditions, often someone will the urine back and forget bath, or sewage poured in the bedpan and do not wash by water, because anti-sealing projection 42 is arranged in exhaust valve pocket 40 bottoms, one end of exhaust plug 16 can be withstood by anti-sealing projection 42, so steam vent 41 can complete closed when exhaust plug 16 is not out of shape downwards at ordinary times, air can flow in the gas cylinder 39 from exhaust elbow 32, shown in arrow among the figure, the air of also namely depositing in the gas blowdown channel 52 passes through air entry 53, admission pipe 55, wireway 47, gas cylinder 39, steam vent 41, exhaust elbow 32, stack 48, exhaust hose 56, exhaust opening 54, blowdown outlet etc. is connected with the external world, so when there being water to pour Shi Buhui in the bedpan water in trap 50 and the inner water tank 43 is siphoned off;

If not anti-sealing projection 42, steam vent 41 can be covered fully at exhaust plug 16 at ordinary times and its complete closed may be made, thereby make and deposit gas blowdown channel 52 and be not communicated with the external world, the air of depositing in the gas blowdown channel 52 is squeezed out by following trap 51, thereby make the pressure of depositing in the gas blowdown channel 52 be lower than atmospheric pressure, water in the trap 50 is siphoned off, when the water in pouring bedpan into is abundant, will make the water in the inner water tank 43 pass through gas cylinder 39, wireway 47, admission pipe 55, air entry 53 flows to deposits gas blowdown channel 52, following trap 51, the blowdown outlet, will continue to intake slightly in the inner water tank 43 like this, and finally continue to flow out from the blowdown outlet, because flow is less relatively, so layman's domestic consumer is difficult to find, thereby wastes a large amount of water.

The specific embodiment two

In the specific embodiment one, stack 48 is arranged in inner water tank 43, between trap 51 and the blowdown outlet exhaust opening 54 is being arranged down, in inner water tank 43 water inlet processes, the air in the aspiration column 35 flows to the blowdown outlet by exhaust elbow 32, stack 48, exhaust hose 56, exhaust opening 54 after by steam vent 41 again; In this specific embodiment two, in inner water tank 43, there is not stack 48, there be not exhaust opening 54 between trap 51 and the blowdown outlet down yet, in inner water tank 43 water inlet processes, air in the aspiration column 35 directly flows to extraneous by steam vent 41 backs, remaining part in this specific embodiment two all with the specific embodiment one in striking resemblances, so operating principle and process are also the same, no longer repeat the way here and state.

In the utility model, at aspiration column 35 T connected in star 36 is set, at inner water tank 43 the protruding hook 44 of T shape is set, and the protruding hook 44 of T shape is inserted in the T connected in star 36, be because when in inner water tank 43, advancing full water because the pressure of water can expand outwardly distortion, such design can make inner water tank 43 be hooked by aspiration column 35, thereby also can not expand outwardly distortion owing to the pressure of water when making inner water tank 43 usefulness plastic or other material do very thinly;

The structure of aspiration column 35 and inner water tank 43 also can be carried out various deformation, as long as the principle of utility model does not change, all various distortion all belong to protection domain of the present utility model.

The utility model cardinal principle is, in the inner water tank drainage procedure, utilize the decline of water level in the aspiration column 35 the air sucking-off of depositing in the gas blowdown channel 52, make the water that gets off from last trap 50 and the water the following trap 51 back of joining fill fast and expire whole piece blow-off line 49, thereby go into siphon fast, and finally the whole siphons of dirt are gone out closet, rather than the rising that resembles in 200620147411.4 and 200880020357.9 patents water level in " the container upper chamber " of utilizing " compression system " or " pressurized air source (42) " in inner water tank water inlet process makes generation in " pressurized air pipeline " or " blowdown path " be higher than the positive air pressure of atmospheric pressure;

In the utility model, deposit the positive air pressure that is not higher than atmospheric pressure in gas blowdown channel 52 and the aspiration column 35 all the time, the every flushing of air of depositing in gas blowdown channel 52 and the aspiration column 35 is once all replaced once with outside air, and in 200620147411.4 and 200880020357.9 patents, " pressurized air pipeline " or " blowdown path " reaches " container upper chamber " the interior air of " compression system " or " pressurized air source (42) " and do not replace with outside air, shifts between " pressurized air pipeline " and " compression system " or " blowdown path " and " pressurized air source (42) " " container upper chamber ";

In 200620147411.4 and 200880020357.9 patents, because " compression system ", " the container upper chamber " of " pressurized air pipeline " or " pressurized air source (42) ", " blowdown path " and outside air sealing, and the positive air pressure that is higher than atmospheric pressure is arranged, so when the water of volume is slightly directly poured in the bedpan and don't is made the inner water tank draining by the draining button, because air is squeezed out " pressurized air pipeline " or " blowdown path ", pressure in " the container upper chamber " of " compression system " or " pressurized air source (42) " can reduce, water level is raise, when water level surpasses " conduit " upper end, water in the inner water tank is siphoned off by " conduit " gradually, water intaking valve is opened, inner water tank is water inlet always unawares on the one hand, water in the inner water tank is another is on the other hand directly siphoned off, and this state is difficult to find as layman's domestic consumer, thereby wastes a large amount of water;

In a plurality of specific embodiment of the present utility model, be provided with the steam vent 41 that not exclusively seals at ordinary times, thereby when a large amount of water is directly poured in the bedpan and don't is made the inner water tank draining by the draining button, though also can being squeezed out, air deposits gas blowdown channel 50, but outside air can add to by steam vent 41 and deposit in the gas blowdown channel 52, the pressure reduction of depositing in the gas blowdown channel 52 is temporary transient, though water level can have rising but recovery at once slightly in the aspiration column 35, water level in the aspiration column 35 can not surpass the upper end c of wireway 47, just can not cause the water in the inner water tank to be siphoned off yet.

In 200880020357.9 claims 1, proposed, " wherein said container chamber has the upper end (100) that is in the same with the full up water level of described inner water tank (52) at least high second water level place " arranged, and in a plurality of specific embodiment of the present utility model, the peak level b in the inner water tank 43 is higher than the upper surface a of aspiration column 35;

Above-mentioned these all are the differences of the utility model and 200620147411.4 and 200880020357.9 patents.
