For achieving the above object, the technical scheme that the utility model adopted is: between oil-containing air exhauster for kitchen and exhausting duct, between toilet ventilation fan and exhausting duct, install one " water-cooled water enclosed air draft exhaust duct block device (hereinafter to be referred as block device) " additional, one end of this block device and smoke exhaust (or ventilation fan) join, and the exhausting duct of the other end and residential building joins.When smoke exhaust or ventilation fan work, dirty gas passes through block device earlier, and then enters exhausting duct discharge open air.Water-cooled water enclosed air draft exhaust duct filtration resistance device enters interface 1 by foul smell, foul smell enters passage 2, foul smell water closes water-cooling channel 3, foul smell passing away 4, foul smell is discharged interface 5, foul smell dividing plate 6, water purification air-purifying chamber 7, water purification air-purifying chamber dividing plate 8, anti-sealing escape plate washer flat board 9, anti-sealing escape riser 10, close water tank 11, cyclic water tank 12, recirculated water inlet 13, water circulating pump 14, circulating water outlet 15, water injection pipe 16, Water filling valve 17, drainpipe 18, water discharging valve 19, overflow pipe 20, water pump and control cabinet 21,22 parts such as waterproof pump box cover plate 22 grades constitute.Its design and operation principle are: before the block device work, earlier by water injection pipe 16 water filling in closing water tank 11.Water injection pipe 16 connects with tap water pipe line, and water filling is closed water discharging valve 19 by Water filling valve 17 controls before the water filling.When water level arrives design and specifies height of water level when waterline 23 when not working (arrive the recirculated water pumping hole), water can overflow by overflow pipe 20, at this moment closes Water filling valve 17, stops water filling.At this moment, the water in the block device is in and satisfies the duty requirement.The supply line of water circulating pump 14 is connected, gauge tap preferably and the switch of smoke exhaust or the switch of ventilation fan be linked together, with same switch control,, also can be provided with separately so that realize allowing circulating pump and the effect that smoke exhaust or abstract gas fan work asynchronously simultaneously.When being connected in foul smell when entering the smoke exhaust of interface 1 or ventilation fan and not working, return from exhausting duct 25 and to irritate that to enter into the dirty gases that foul smell enters in the passage 4 disconnected by foul smell dividing plate 6 and the water resistances that close in the water tank 11, can't pour in down a chimney, return to indoor, thereby realize thoroughly eliminating the purpose of returning flavor, taint of odour.When smoke exhaust or ventilation fan are started working, because water circulating pump 14 synchronous initiations simultaneously (are adopted same switch control.Control water circulating pump 14 as other by switch, should first start cycles pump, back starting smoke exhaust or ventilating fan), close water in the water tank 11 and be recycled pump 14 and be sent to cyclic water tank 12, needed position when closing water levels in the water tank 11 this moment and dropping to smoke exhaust or ventilation fan work when circulating pump work (that is waterline 24) through recirculated water inlet 13.Because water circulating pump 14 continuous operations are full of the water that is pumped in the cyclic water tank 12, and form press water, from circulating water outlet 15 ejections, the anti-sealing escape riser 9 of warp flows into and closes water tank 11.Meanwhile, the dirty gas by smoke exhaust or ventilation fan are sent enters interface 1 through foul smell and enters, and enters passage 2 by foul smell, closes water-cooling channel 3 through foul smell water, enters foul smell passing away 4 again and discharges outdoor.This moment, it was open-minded with foul smell passing away 4 to make foul smell enter passage 2 owing to close the decline of water level in the water tank 11.When smoke exhaust or ventilation fan work, be gas with foreign flavor impossible take place pour in down a chimney phenomenon.When smoke exhaust or ventilation fan quit work, water circulating pump 14 also quits work simultaneously, water in the cyclic water tank 12 can automatically return to and close in the water tank 11 via water circulating pump 14 (using not the water pump with non-return valve), makes the water levels that close in the water tank 11 return to original position.Again seal water and close water-cooling channel.Because in the smoke exhaust course of work, have a certain amount of steam etc. and be cooled and condense and stay, the water levels that close in the water tank 11 are increased, at this moment, the water of increase can be discharged automatically by overflow pipe 20.

For the suitable for reading and foul air flue of avoiding overflow pipe 20 communicates, prevent dirty gas via in overflow pipe 20 inlet chambers, adopt water purification pure qi (oxygen) dividing plate 8, form water purification air-purifying chamber 7.The effect of water purification pure qi (oxygen) dividing plate 8, the one, can block dirty gas and enter, prevent to form to pour in down a chimney to return flavor through overflow pipe; The 2nd, can block greasy dirt and enter, prevent that greasy dirt from stopping up the spilling water mouth of pipe, because of the proportion of greasy dirt is lighter than the proportion of water, can float on the surface.

Because employed water all will contact impurity such as greasy dirt, dirty gas every day in the block device, is easy to go bad, addle, the greasy dirt of staying in the water tank also needs to get rid of, so will often or regularly replace.During discharging, finish by drainpipe 18 and water discharging valve 19.In addition, water level can not surpass the design water level height during water filling, more can not allow current advance exhaust duct or enter interface 1 from foul smell and flow out.So, must guarantee the open height of overflow pipe 20 and unimpeded and possess enough discharge abilities.For this reason, make suitable aperture to the water inlet of water injection pipe 16, guarantee to inject flow and be far smaller than flooded traffic.Overflow pipe 20 should be in unimpeded state all the time simultaneously, can not add valve.Be convenient to drain by the unnecessary water yield that steam condenses at any time.

The block device that the utility model is given can use as a product separately; Also can directly constitute one, form a kind of new product and use with smoke exhaust, ventilation fan.

The utility model is rational in infrastructure, design is tight, can block and eliminate the refluence of dirty gas with foreign flavor in residential kitchen and the toilet air draft exhaust duct up hill and dale and return the filling problem, thereby thoroughly solved since the own oil-containing air exhauster for kitchen, had one of puzzlement huge numbers of families since the toilet ventilation fan to generally acknowledge it is a chronic disease difficult problem and the common fault that thoroughly to eliminate greatly.In addition, it can also reduce the atmosphere pollution that brings owing to mist extractor in very big limit ground.Can also effectively block the insect passage of easily stretching between the neighbourhood.
