Description

The toilet deodoriser

The utility model belongs to feedwater, water discharge technology field, relates to the sanitary installation that a kind of lavatory is used, particularly a kind of toilet deodoriser (E03D9/00, E03D11/13).

Chinese patent CN2064382U discloses a kind of " the movable toilet of band deodorizing ", the back bevel in its chamber is equipped with the air draft short tube by top, the inner headed face of air draft short tube is interference fit with the rubber ring that is enclosed within on the union of plastic flexible pipe one end, the other end then is connected with the air intake of centrifugal electric hair-dryer, has formed odor removal.Although should " the movable toilet of band deodorizing " adopt stepless adjustable wind speed, can arbitrarily adjust the deodorizing blast, but weak point is because this binding site position of only present chamber of its air outlet and air draft short tube, so in case the deodorizing blast is excessive, the phenomenon that ight soil inspiration air outlet might occur, if and the deodorizing blast is too small, then can make the deodorizing effect variation again.

The purpose of this utility model is to provide a kind of toilet deodoriser, to overcome the existing in prior technology defective.

Task of the present utility model is finished in the following manner, a kind of toilet deodoriser, form by air inlet pipe, exhaust plant and stack, described exhaust plant is made of motor, motor shield, fan and blower-casting, electric machine main shaft and fan shaft are fixed, on blower-casting, offer simultaneously air inlet port and exhaust opening respectively, its key is to be fixed with admission pipe on the air inlet port of air inlet pipe, the shape of this admission pipe and toilet inner wall shape suitable for reading matches, and offers some suction holes simultaneously on the tube wall of admission pipe.

For convenience air inlet pipe and admission pipe is connected, be preferably in its connecting portion and set up a tee piece, one end of tee piece is connected with air inlet pipe, two ends are connected with two ports of admission pipe more in addition, so just can conveniently adjust the length of admission pipe, be beneficial to be used with the toilet of different model.

The power switch of control exhaust plant duty preferably adopts key switch, this key switch can be fixed on the suitable position of seat cushion circle below, during use, in case the seat cushion circle is lain on the toilet, the effect of present packing ring self gravitation down or user when being sitting in above the seat cushion circle, the button of above-mentioned key switch will inwardly be pressed into, sheet metal in the key switch will be in contact with one another, make power connection, exhaust plant gets electric work, and the gas in the toilet cavity is sucked out.After finishing using, only the seat cushion circle need be lifted and place former inactive state, the button of above-mentioned key switch will outwards eject, and power supply is cut off, exhaust plant is quit work, so the user need not to remove to open or close power switch in addition and just can conveniently use this toilet deodoriser.

In order to adapt to different users's use habit, can in the operating circuit of motor, install governor additional, in order to the intensity of control suction and discharge.Described governor can be selected adjustable resistance for use, also can select other speed governing device of selling on the market for use.

Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail.

Fig. 1 is toilet deodoriser general structure schematic diagram;

Fig. 2 is the exhaust plant structural representation in the toilet usefulness deodoriser;

Fig. 3 for toilet with deodoriser and the toilet schematic diagram that cooperatively interacts;

Fig. 4 is the toilet structure schematic diagram that has deodoriser.

With reference to Fig. 1, the toilet deodoriser is made up of air inlet pipe 1, exhaust plant 2 and stack 3, is fixed with admission pipe 4 on the air inlet port of air inlet pipe 1, the shape of this admission pipe 4 and toilet inner wall shape suitable for reading matches, and offers some suction holes 5 simultaneously on the tube wall of admission pipe 4.In conjunction with Fig. 2, above-mentioned exhaust plant 2 is made of motor 21, motor shield 26, fan 22 and blower-casting 25, and the rotating shaft of the main shaft of motor 21 and fan 22 is fixed, and offers air inlet port 23 and exhaust opening 24 simultaneously on blower-casting 25 respectively.

With reference to Fig. 3, the power switch of exhaust plant 2 adopts key switch 7, this key switch 7 directly is fixed on the below of seat cushion circle 91, during use, in case seat cushion circle 91 is lain on the toilet 9, because when the gravity of seat cushion circle 91 self or user are sitting in above the seat cushion circle 91, the button of above-mentioned key switch 91 will inwardly be pressed into, sheet metal in the key switch 91 will be in contact with one another, make power connection, exhaust plant 2 gets electric work, and the suction hole 5 of gas on admission pipe 4 tube walls in toilet 9 cavitys is by air inlet pipe 1 sucking-off, and send into sewer 92 by stack 3 and extract duct 93 by exhaust plant 2, after finishing using, only seat cushion circle 91 need be lifted and place former inactive state, the button of above-mentioned key switch 7 will outwards eject, power supply is cut off, and exhaust plant 2 is quit work.It can also be seen that from Fig. 3 the admission pipe 4 that is connected on the air inlet pipe 1 is fixed on the bottom of seat cushion circle 91 inner rings, and also is provided with indicator lamp 8 on the present packing ring 91, in order to show the duty of exhaust plant 2.

With reference to Fig. 4, this figure provides a kind of degree closet that has deodoriser, exhaust plant 2 is set directly at the back of toilet 9, key switch 7 also is fixed on the below of seat cushion circle 91,4 of admission pipes are fixed on toilet 9 inwall position suitable for reading, and air inlet pipe 1 directly is opened on the body of toilet 9, the air inlet pipe 1 of admission pipe 4 through being opened on toilet 9 bodies inserts exhaust plant 2, and the exhaust opening 24 direct extract ducts 93 through being opened on toilet 9 bodies of exhaust plant 2 lead to sewer 92, in the present embodiment, also being provided with indicator lamp 8 on the seat cushion circle 91, equally also is the duty that shows exhaust plant 2 with adopting.

Because sewer pipe is communications and liaison everywhere, and the gas and the pressure that suck in the unit interval are limited, and the device that prevents that foul smell from overflowing is arranged again in the toilet still more, overflow so the gas of discharging is unlikely in toilet.If consider that the wall or the window that also stack can be passed the washroom directly discharge by the convenience of dress.

Consider that there was dampness in the air in the washroom,, can certainly fix electric wire with traditional method in order to prevent that electric leakage also for attractive in appearance, preferably can be adsorbed on electric wire on ceramic tile or the wall with sucker.

Because the utility model set up admission pipe on the air inlet port of air inlet pipe, so no matter the deodorizing blast has muchly, the phenomenon of ight soil inspiration air outlet also can not appear, therefore can obtain good deodorizing effect.Owing to the connecting portion at air inlet pipe and admission pipe has additional a tee piece, so just can arbitrarily adjust the length of admission pipe, simultaneously so help being used with the toilet of different model.

Because the key switch of control exhaust plant duty is fixed on the below of seat cushion circle, so the user need not to remove to open or close power switch in addition and just can conveniently use this toilet deodoriser.

Owing in the operating circuit of motor, add governor, so can arbitrarily adjust the intensity of suction and discharge according to different users's use habit.

The utility model is simple in structure, and is with low cost, and the enterprise that is suitable for different scales such as toilet manufacturing enterprise or plastics plant, switchgear factory produces, because this product is applicable between domestic hygiene therefore have good market prospects and economic benefit.
