Detailed description of the present invention

By the reference the description of the drawings, will be readily appreciated that the present invention, the parts of being represented by reference number in the accompanying drawing are consistent with following explanation.In each view, same parts are represented with same reference number.

Fig. 1 shows the siphonic flush toilet 11 of common used type and the device of the present invention 20 that is mounted thereon.Such flush toilet is commonly referred to water closet.The mechanism of operating such flush toilet makes the bottom in toilet pond 12 and the upwards crooked discharge portion 27 of flush toilet keep certain water level backwards, the toilet pond directly is communicated with this discharge portion, thereby, formed to sewer line that sewer or septic tank link to each other in the obstruction of gas, otherwise gas will enter the living area at flush toilet place.Under normal or idle situation, have two surfaces: a upwards crooked backwards discharge portion 27 that is arranged in flush toilet, another is arranged in the toilet pond 12 of flush toilet.When toilet pond 12 is full of rapidly by the water from flushing tank or flushing valve, water level in the upwards crooked backwards discharge portion 27 of toilet pond 12 and flush toilet rises, reach up to the water level of discharge portion and to make water be spilled over to discharge pipe 16, this will cause siphonic effect and water in the toilet pond 12 of more promptly finding time and contained refuse thereof.When the water that is fed to toilet pond 12 slows down, water level in the toilet pond is reduced to enough low level, so that air can be inhaled into crooked discharge portion 27 backwards, thereby ended siphonic effect, make water level be filled to roughly original level again, thereby formed effective sealing once more the gas in the sewer.

As everyone knows, the smell of disliking in the bathroom is from flush toilet, especially in use.Many inventors in the past early have recognized that the urgency of eliminating these smells, and these smells major part before diffusion concentrates in the room air.The air that some inventor has selected to have stench is discharged in the blowoff line in the building at toilet place.Yet previous searcher is with respect to traveller's objective demand, and the traveller need carry the device that can detachable mounted be used for flush toilet.Modern motor and compact power, for example battery or be used for the safe utilization of the tame electricity consumption in bathroom can provide safety to use easily, and this does not accomplish in the past.And everyone clearly realizes that and does not make disagreeable smell at objective demand indoor even diffusion around toilet now.

Device of the present invention is used for the smell of flush toilet is removed, and, make its formations portable, be easy to installation or plug-in mounting more correctly.

Found out clearly that by Fig. 1 air space 25 is connected with air in the sewer pipeline 15 by discharge pipe line 16, pipeline 15 feeds atmosphere, and the gas in the blowoff line of installing in the building 13 is discharged.The inventive system comprises fan, it pumps to air space 25 with the air in the flush toilet 12, enters sewer pipeline 15 again, thereby, prevent that the smell of disliking is diffused into it from flush toilet around.

Fig. 2 shows the detailed view of the device of one embodiment of the present of invention, and this device comprises: fan 30, and it has blower-casting 32, and housing 32 has inlet port 34 and outlet opening 36; Flexible pipe 40, it is connected with floss hole 36, takes away waste gas from fan 30; With support 44, it is installed on blower-casting 32, and matches with the apical margin of toilet removably, thereby, be suspended under the apical margin of toilet removably, be arranged in described toilet pond.During use, two waters surface that pipe 40 passes in the described toilet extend, and fan inlet port 34 then is arranged in the toilet pond, thereby force to take away the air in the toilet pond, and air is drained in the drainage pipeline 13.Obviously, pipe 40 must be enough soft, so as crooked in the curved surface of trap, but can be too not soft so that can not be pushed into suitable position.A lot of plastic materials are suitable for this pipe.Any those of ordinary skills all can select suitable material.Fan power supply shown in Fig. 2 mainly is a household outlet, and for safety, it has adopted the insulating transformer (not shown) to reduce voltage.

In the end of the pipe shown in Fig. 2 40, be provided with simple one way valve 48, its permission is flowed out from pipe.When pipe was inserted in the water in the flush toilet 12, the anti-sealing of this valve entered pipe 40.Shown valve 48 is general type, and it is suitable for making condensation product from entering gutter being lower than the airline of moving under the atmospheric pressure, as air conditioning equipment of car.This valve is made by flexible plastic or rubber-like material, and is configured as its upper end and 50 can be assemblied on the pipe, and its lower end 52 is flat only to stay a narrow slit as opening.By the sealing of the formed narrow slit of back-pressure, can prevent any backflow.Fig. 3 shows the lateral view of this valve 48.

Fig. 4 shows another embodiment of the present invention, and it comprises: blower-casting 32, and fan motor 33, support 44, and the housing 56 that is used for battery, this support 44 is suitable for being seated on the apical margin of flush toilet, and battery container 56 is suspended at the outside of toilet.Exist but not shown by the electric wire of the battery supplied electric energy that is arranged in battery container 56 and fan motor 33.

Fig. 5 shows another embodiment again of the present invention, and it comprises: blower-casting 32, fan motor 33, support 44, and the housing 56 that is used for battery, this support 44 is suitable for being seated on the apical margin of flush toilet, and battery container 56 is with the inside of battery support in toilet pond 12.Exist but not shown by the electric wire of the battery supplied electric energy that is arranged in battery container 56 and fan motor 33.

The present invention described above comprise functional object lesson that has that it quotes, but the applicant wishes to comprise within the scope of the invention some improvement of particularly not mentioning here to the conspicuous various improvement of those of ordinary skills.The applicant wishes that the present invention is only limited by the scope of claims.
