Abstract

The utility model discloses a deodorizing device for toilet bowls, comprising a tubular body which can be connected between the pipeline of an air pump and the overflow pipe of a water tank. The side wall of the utility model is provided with an overflow opening to ensure the overflow function of the original overflow pipe, and the overflow opening is covered by a floating body valve hinged on the outer side wall of the utility model. The utility model which has the advantage of simple structure can be arranged in the water tanks of the existing toilet bowls, and the air pump pumps smell in the toilet bowls by the overflow pipe directly. Therefore, no smell exists in toilets, and the purpose of deodorization is achieved. The tubular body can also be combined with the overflow pipe into a whole. The switch of the air pump can be in linkage with a turn knob controlling the water drain of the water tank or can be arranged on a toilet seat to stop automatically during flushing.

Description

Deodorizing device for closet

The utility model relates to a kind of odor removal, relates more specifically to a kind of flush toilet deodoriser.

At present, the deodorizing method of flush toilet adopts the mechanical means of induced draft fan in addition except the chemical method that adopts perfume or deodorant.When using the lavatory, start induced draft fan to be evacuated to the foul smell in the washroom outdoor by pipeline.

Yet, be air whole washroom in because induced draft fan takes out, so efficient is not high, and when finishing washroom door unlatching with the lavatory, certainly will mixes mutually with mistress's air, make the mistress also have foul smell.

For this reason, the purpose of this utility model promptly provides a kind of flush toilet deodoriser, and it can be installed in the toilet flush, directly aspirates the foul smell in the toilet, and simple in structure, easy for installation.

For reaching this purpose, flush toilet deodoriser of the present utility model, comprise a tubular body, its upper end open can link to each other with pump-line, its lower ending opening can be connected on the water-closet tank bleed off pipe, near a spout hole being arranged on the tube wall of lower end, be hinged with a buoyancy aid valve that can cover described spout hole on the pipe outer wall on the spout hole.

Tubular body also can be made one with water tank overflow pipe.

Air exhauster is connected to the tubular body upper end open by pipeline, thereby can directly the foul smell in the toilet is evacuated to the open air or reaches the deodorizing purpose through charcoal treatment.Because foul smell does not diffuse in the washroom as yet and promptly is sucked, so there is no foul smell in the washroom.And this apparatus structure is simple, can be installed on the bleed off pipe in the existing water-closet tank, perhaps makes one with bleed off pipe, therefore need not existing toilet is changed or only need be changed bleed off pipe, obviously installs very convenient.

For characteristics of the present utility model and advantage are had further understanding, embodiment is described in detail below in conjunction with accompanying drawing.

Figure 1 shows that the flush toilet schematic diagram when the utility model deodoriser is installed.

Figure 2 shows that the stereogram of the deodoriser of an embodiment of the utility model.

Figure 3 shows that the sectional view of Fig. 2 deodoriser.

Figure 4 shows that the schematic perspective view when Fig. 2 deodoriser buoyancy aid valve is opened.

Figure 5 shows that the stereogram of the deodoriser of another embodiment of the utility model.

Please referring to Fig. 1, be depicted as the schematic diagram of the flush toilet that the utility model deodoriser is installed earlier.Mainly comprise (not shown) such as water inlet pipe, water level float in its water tank 10, the toilet water level water inlet pipe 13 that also comprises bleed off pipe 12 and be used for guaranteeing water level in the toilet.Wherein bleed off pipe 12 leads in the toilet.

Principle of the present utility model promptly is to connect a toilet deodoriser 20 of the present utility model on bleed off pipe 12, thereby utilizes air exhauster 30 foul smell in the toilet to be extracted out by bleed off pipe 12 and be evacuated to the open air or handled through an activated carbon 31 by pipeline.

Please in conjunction with consulting Fig. 2,3 and Fig. 4.Flush toilet deodoriser 20 of the present utility model comprises a tubular body 1, and tubular body 1 upper end open can link to each other with the intake duct of air exhauster 30, and lower ending opening can be socketed on the upper end open of bleed off pipe 12.

In order to keep the relief function of bleed off pipe 12, on the wall of tubular body 1, have spout hole 2, after tubular body 1 was socketed on the bleed off pipe 12, the position of spout hole 2 just in time was in the upper end of bleed off pipe 12 and highly locates.On tubular body 1 inwall, a pair of limited block 3 can be installed, to guarantee the height of spout hole 2.Therefore, limited block 3 should be positioned at the lower edge of spout hole 2.

One buoyancy aid valve 4 is arranged outside spout hole 2, and its upper end is hinged on tubular body 1 outer wall of spout hole 2 tops.Buoyancy aid valve 4 can comprise a hollow body 4a.When ordinary water level, valve 4 is linked in tubular body 1 outer wall and covers spout hole 2 by gravity like this, and when air exhauster 30 is bled this capping better effects if, therefore can prevent that water or the steam in the water tank is inhaled into air exhauster 30 and influences air exhauster 30 performances.When water tank breaks down and (see figure 4) when water level excessively goes up in the water tank, valve 4 turns under buoyancy and opens spout hole 2, makes bleed off pipe 12 play the overflow effect.

But also perforate on tubular body 1 wall is to allow toilet water level water inlet pipe 13 from wherein passing through.Joint 5 can be installed to admit water level water inlet pipe 13 outside this perforate.

Fig. 5 has shown the toilet deodoriser of another kind of form, and different with the foregoing description is that it and bleed off pipe 12 are made one.

Toilet water level water inlet pipe 13 wherein also can insert from the perforate on the gutter 15 of bleed off pipe 12 bottoms 16.

The switch of air exhauster 30 can link with the control turning handle 14 of water tank 10, with autostop when discharging water flushing.Also can be installed on the toilet seat 20, when toilet user was sat down, air exhauster 30 was opened, and when toilet user stood, air exhauster 30 was shut down.Shutting down when discharging water bath is in order to prevent that air exhauster 30 from making moist.
