Abstract

A deodorant floor drain comprises a base. A floor drain core which is formed by sleeving an inner tube in an outer tube is arranged on the base. The deodorant floor drain is characterized in that a duckbill valve which is opened by the pressure of water drained in the floor drain is arranged at the bottom of the inner tube, a large-aperture end of the duckbill valve is sleeved at the bottom of the inner tube, and a flat-mouth end of the duckbill valve is closed in a clinging manner. The duckbill valve is arranged at the bottom of the inner tube of a spool, so that the floor drain can still effectively stop bad smell and mosquitoes of a sewer from entering an indoor environment when a water seal fails; the floor drain has an effect of preventing sewage from overflowing under the condition of blockage of a drainage pipe; and moreover, the deodorant floor drain is difficult to block, and impurities are convenient to remove.

Description

Odour-proof floor drain

Technical field

The utility model relates to a kind of odour-proof floor drain.

Background technology

As a kind of foundation drainage facility, floor drain is widely used in places such as kitchen, shower house, washroom.At present, floor drain is the pedestal 1 that is embedded in ground and drainage pipe junction, the floor drain core that pedestal 1 is provided with grate 2 and extends below to ground of comprising as shown in Figure 1 usually, and floor drain core comprises the interior pipe 4 and outer tube 5 that is nested with together; Sewage manages 4 in grate 2 flows directly into; Outer tube 5 bottoms sealings, and outer tube 5 sidewalls are provided with an outfall 3 near upper end, and the water that flows out through outfall 3 directly flows in the drainage pipe; Pipe 4 lower ends in the lower edge of outfall 3 is higher than; Make the water that remains in the outer tube 5 can exceed interior pipe 4 bottoms, and then pipe 4 bottom water seals in making, played certain isolated sewer foul smell to the indoor effect of returning flavor.

But in daily use; This floor drain exists problem: because for a long time not to the floor drain internal drainage; Or owing to the natural evaporation meeting causes being used to the water minimizing that intercepts in the floor drain even drying up; Can't internally manage the bottom and seal, pipe is connected with drainage pipe in making, and floor drain can't realize that just it prevents to return the effect of flavor; When drainage pipe stopped up, sewage can advance indoor through the floor drain overflow; Mosquitoes such as cockroach can pass water seal through in the floor drain inlet chamber, have a strong impact on people's life.

The utility model content

To the problem that exists in the prior art; The purpose of the utility model is to provide a kind of odour-proof floor drain; This odour-proof floor drain is provided with a duckbill valve through the interior pipe bottom at spool; Make this floor drain when losing water seal sealing, still can effectively stop in the foul smell, mosquito inlet chamber of sewer; Under the situation that drainage pipe stops up, play the effect that prevents sewage overflow; And this floor drain is difficult for stopping up, removes foreign material conveniently.

For addressing the above problem; A kind of odour-proof floor drain of the utility model; Comprising that pedestal, pedestal are provided with by interior pipe and outer tube is nested with the floor drain core that forms; The pipe bottom is provided with the duckbill valve that a dependence enters the hydraulic pressure unlatching of this floor drain in said, and the closure that reclines is held for its flat mouthful in pipe bottom in the heavy caliber end of duckbill valve is sleeved on.

Further, said duckbill valve is processed by elastomeric material.

Further, said duckbill valve is fixed on said interior pipe bottom through fastening devices.

Further, said fastening devices is included in said interior pipe bottom and circumferentially is provided with cannelure at least together in the suit place mutually with said duckbill valve, on duckbill valve, is provided with annular protrusion with the cannelure corresponding section.

Further, said interior pipe bottom setting is extend out tubaeform.

Further, offer two near upper end on the said outer tube wall and be oppositely arranged outfall.

The utlity model has simple in structurely, on the basis of existing floor drain, installed duckbill valve additional, make floor drain under long-term anhydrous situation, still can have the function that prevents to return flavor.

Description of drawings

Fig. 1 is the structural representation of existing floor drain;

Fig. 2 is the sectional drawing of floor drain in the utility model;

Fig. 3 is an a place partial enlarged drawing among Fig. 2.

Among the figure: pipe, 5 outer tubes, 6 duckbill valves in 1 pedestal, 2 grates, 3 outfall, 4.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.

A kind of odour-proof floor drain as shown in Figures 2 and 3; Comprise the floor drain core that pedestal 1, pedestal 1 are provided with grate 2 and extend below to ground; Wherein, floor drain core comprises the interior pipe 4 and outer tube 5 that mutual sheathing is provided with, and the duckbill valve 6 that a dependence enters the hydraulic pressure unlatching of this floor drain is set in interior pipe 4 bottoms; The closure that reclines is held for its flat mouthful in pipe 4 bottoms in the heavy caliber end of duckbill valve 6 is sleeved on.Duckbill valve is processed by elastomeric material and is fixed on interior pipe 4 bottoms through fastening devices; Wherein elastomeric material is preferably rubber; Fastening devices is preferably pipe 4 bottoms that included and circumferentially is provided with cannelure at least together in the suit place mutually with duckbill valve 6; With on duckbill valve 6, be provided with annular protrusion with the cannelure corresponding section, through the annular protrusion holding with cannelure in make duckbill valve 6 be fastened in the pipe 4 on.Certainly, a kind of concrete form of fastening devices only has been described here, also can have been used other known fixed forms such as clip to fix, glue together fixing etc., just the preferred version of fastening devices is convenient to the dismounting of duckbill valve 6 more in the present embodiment.Interior pipe 4 bottoms are provided with and are extend out tubaeform.Offer two near upper end on outer tube 5 sidewalls and be oppositely arranged outfall 3.Through two outfall that are oppositely arranged 3 are set, can better sewage be discharged.

Water is managed in grate flows under action of gravity, and the closed duckbill valve unlatching of compressing, thereby flows into outer tube, realizes draining thereby arranged like drainage pipe by the outfall of outer tube again.Owing to reason such as do not use to cause in the outer tube drawdown for a long time and be lower than in during the pipe bottom the closure because flat mouthful of end of duckbill valve reclines, foul smell, mosquito etc. leaks in the inlet chamber impenetrably.

The utility model is not limited to above-mentioned embodiment, above said just for the utility model is described, so long as the various variation that meet the utility model thought are all within the protection domain of the utility model.
