Description

A kind of toilet air exhausting device

Technical field

The utility model relates to a kind of accessory of toilet.

Technical background

Toilet is very general a kind of sanitaryware, but the foul smell that toilet is produced when people's defecation, be could be from the indoor washroom that gives off by exhaust fan above the washroom ceiling or the exhaust fan above the window, foul smell in discharge process in the toilet seat basin is diffused into indoor earlier and then is discharged into outdoor, at this moment allow the people feel that foul smell has been full of whole washroom, feels very ill the people.If can above the seat basin of toilet an air exhausting device be installed, it is outdoor that stink that people produce when defecation is discharged in the seat basin immediately, rather than etc. defecation finish when leaving basin, treat that foul smell evaporates and could be emitted by exhaust fan in the seat basin.

Seat ring above the toilet is an accessory that must be equipped with on the toilet, and it is installed in following of toilet and goes up and supported by seat basin upper end, and the loose end of seat ring can be along the axle rotation of fixed end.Seat ring has a circle of smooth surface just for the people that use toilet provide a comfortable seat, and the excreta that the middle part produces can make people's defecation the time bleed in the seat basin of its below one big mouthful we be called inner ring.The one side that seat ring contacts with people's buttocks is made up of smooth curved surface, and we claim this simultaneously to be the front of seat ring usually, and with the contacted one side in toilet seat basin upper end be the back side; Feel comfortably cool when people are used, it is comparatively wide that the periphery of seat ring is all done, and the width of seat basin upper end is just narrow many with respect to the width of seat ring periphery, and seat ring is the top that is suspended in a basin near the part of seat ring inner ring in use.

If we make it be suspended in the top of a basin part that the exhaust tube that is provided with many aspirating holes above is installed in the close inner ring of housing washer back face; Perhaps, make the top of the fixing present basin of this root exhaust tube with the edge of the inboard, upper end in the directly fixing present basin of this root exhaust tube; Again by a centre be provided with exhaust fan, two ends respectively with exhaust tube and washroom in sewage mouth or a pipeline linking to each other of soil pipe.When people's defecation, open exhaust fan, just can the foul smell that people produce when the defecation be discharged in above-mentioned sewage mouth or the soil pipe immediately, solved the problem that could discharge after the washroom stink diffusion, more comfortable when making people use toilet.

Summary of the invention

The purpose of this utility model just is to use an exhaust fan and an one way valve; The edge of the inboard, upper end in the present basin or above the edge of inner ring is installed one, be provided with the exhaust tube of several aspirating holes at the back side of seat ring; Be provided with one and be linked in sequence form one mutually from the aspirating hole to the soil pipe or the path of the gas of sewage mouth by exhaust tube, mozzle, admission pipe, one way valve, exhaust fan, stack and threeway or floor drain ventilation opening; Exhaust fan is discharged into the foul smell in the seat basin in soil pipe or the sewage mouth by above-mentioned this path; One way valve prevents that the foul smell in soil pipe or the sewage mouth from returning indoor.

Toilet air exhausting device of the present utility model has seat ring, exhaust tube, exhaust fan, one way valve, threeway or floor drain ventilation opening, seat ring are the upper ends of laying present basin, and the exhaust tube that is provided with several aspirating holes above is fixed on the edge or the seat basin inner top side edge of housing washer back face inner ring; By mozzle exhaust tube is communicated with admission pipe, threeway or floor drain ventilation opening are communicated with stack, exhaust fan be connected between admission pipe and the stack after one way valve is communicated with, constitute one by extract opening to threeway or to the gas passage the floor drain ventilation opening; It is characterized in that: the be fixed inboard edge in present basin upper end or be fixed on the edge of housing washer back face inner ring of exhaust tube that is provided with several aspirating holes in the above; The outside that present basin is set is discharged into above-mentioned soil pipe or the interior exhaust fan of sewage mouth to the gas in the seat basin; One prevents that the foul smell from above-mentioned soil pipe or sewage mouth from returning indoor one way valve; Can receive threeway above the soil pipe or one to stack for one and can receive floor drain ventilation opening above the sewage mouth to stack.
