Description

The straight odour-proof floor drain

Technical field

The utility model relates to a kind of sewer floor drain.

Background technology

Existing sewer has multiple structure with floor drain, comprise straight, inverted bowl type (bell-jar) or the like, the shortcoming of tradition inverted bowl type floor drain is that current must be discharged sewage by the zig zag of two 180 degree about the extremely narrow annulus warp during draining, the hydraulics extreme difference, deposit dirt forms and stops up easily, removes very difficulty of dirt, must take down bell jar, can take out amassing thing.Common people do not understand the bell jar effect, do not know what is water seal yet, unobstructed and the removing dirt convenience for draining, often that bell jar is discarded, this has just destroyed the floor drain water seal, the ducted toxic and harmful of living drainage, just may scurry into washroom, kitchen from floor drain, cause the severe contamination of room air, influence the safety and sanitation of resident family, threat to life safety when serious.Other water seal depth is very shallow in addition, only has more than 20 millimeter, is evaporate to dryness in several days, as untimely moisturizing, will constantly distribute foul smell, deepens 50 millimeters of water seals even transform, only times that delay not emit in several days foul smell more.But water seal is deepened, and can make hydraulics worse, and deposit dirt is even more serious.Other odour-proof floor drain also is equipped with annex because of inside, is carried secretly fiber, hair etc. by draining easily and snarls and influenced sealing effectiveness, causes foul smell to overflow.

The utility model content

The utility model provides a kind of sewer floor drain, need not water seal, not only has good odour seal performance, and following water is unobstructed, and can prevent functions such as sewage returns in the inlet chamber such as excessive, insect, bacteria breed.

A kind of straight odour-proof floor drain comprises porose panel, securing member, shell and rubber open and close device, the soft rubber that the rubber open and close device is one of the forming, by the upper end fixedly outer and lower end tenon shape automatically the outfall of folding form.

The upper end outward flange of the outfall of above-mentioned rubber open and close device is symmetrically arranged with a pair of extruding salient point.

Above-mentioned housing comprises upper shell and lower house, and upper shell is provided with the draw-in groove that matches with the securing member projection, and the anti-hydrofoil ring that has drain hole is arranged at lower house top.In case local area water when the floor drain outer wall seeps water so that sewage is imported drainage pipe, prevents the floor infiltration.

The draw-in groove of above-mentioned upper shell is a step draw-in groove or by wide gradually narrow draw-in groove.

The inwall of the fixedly outer of above-mentioned rubber open and close device also is arranged with a pair of extrusion lug.

The floor drain of said structure straight, when current pass through, when arriving rubber open and close device place, open and close device under hydraulic action at the bottom of the outfall mouth open, current are discharged; During not draining, the rubber open and close device is the auto-closing outfall under the elastic rubber effect, reaches the function of sealing, does not worry that foul smell comes out from the ground leak; Because of this floor drain does not need not done foul smell and escaped so worry the floor drain water seal with the water seal sealing.Owing to be straight structurally, the self-purification ability extra-heavy, any rubbish can both wash away, inner absolutely empty without any the annex that can tangle hair, mouth opens at the bottom of during draining, and current one lead to the end, in the time of accomplishing to get rid of sewage such as having fiber, hair, paper scrap, silt particle, can not produce obstruction, inside does not need to clear up; The outfall closure reaches deodorization, anti-returns water during not draining, bacteriological protection grows and protection against insect climbs into functions such as indoor.The securing member that the utility model adopted and the fit structure of upper shell, adopt step or by wide gradually narrow formula draw-in groove, securing member can not be taken down easily, needs just can take out securing member by the certain orientation rotation, to be convenient for changing internal component and floor drain to be used as inspection hole to use.

The specific embodiment

Shown in Fig. 1-4, the utility model provides a kind of straight odour-proof floor drain, comprise porose panel 1, securing member 2, shell 3 and rubber open and close device 4, housing comprises upper shell 31 and lower house 32, upper shell 31 is funneling, the upper surface is provided with backstop boss 311, the upper surface shape has square and circular two kinds, in order to place porose panel 1, the first stretched sidewall 313 that is connected with the first inclined-plane boss 312 has two draw-in grooves 314, draw-in groove 314 is the step slotted eye, matches with securing member 2 projections 21, and this draw-in groove 314 also can adopt by by wide gradually narrow structure; The first stretched sidewall 313 inwardly shrinks and forms the second inclined-plane boss 315 and the second stretched sidewall 316.As shown in Figure 5, first benchboard 312 of above-mentioned upper shell also can adopt the shape of straight wall, and the current that are beneficial to bigger flow pass through fast.Lower house 32 is provided with an anti-hydrofoil ring 322 that has a drain hole 321, in case local area water when the floor drain outer wall seeps water so that sewage is imported drainage pipe, prevents the floor infiltration.Securing member 2 is the inclined-plane snap ring of hollow, and sidewall is provided with two projections 21, matches with the draw-in groove 314 of upper shell.The soft rubber that rubber open and close device 4 is one of the forming, by the upper end fixedly outer 41 and lower end tenon shape automatically the outfall 42 of folding form, the upper end outward flange of outfall is symmetrically arranged with a pair of extruding salient point 43, just push mutually with the second stretched sidewall 316 of upper shell, make that 42 end of the outfall mouth of open and close device 4 is closed fully, prevent peculiar smell and foreign matter return into.The fixedly outer 41 of rubber open and close device 4 is the inclined-plane, and its lower limb also is provided with the extrusion lug 44 of a symmetry, makes that 42 end of the outfall mouth of open and close device 4 is closed fully.

During installation, rubber open and close device 4 is built in the upper shell 31, its fixedly outer 41 with during second inclined-plane 315 matches, the projection 21 on securing member 2 two opposite side suitable for reading and the draw-in groove 314 of upper shell are matched, rubber open and close device 4 is stuck in the upper shell 31 closely, projection 21 is forwarded in the slotted eye of topping bar of draw-in groove 314, as dismantling, only need it is screwed in the slotted eye of getting out of a predicament or an embarrassing situation, securing member 2 can be taken out, realize freely loading and unloading; Then lower house 32 is nested with on the second stretched sidewall 316 of upper shell 31, porose panel 1 is placed on the upper shell 31 gets final product then.

As shown in Figure 6, this floor drain is rubber open and close device 4 auto-closing outfall under the elastic rubber effect when not draining, reaches the function of sealing; As shown in Figure 7, pass through as the current current, when arriving rubber open and close device place, open and close device is gone to the bottom in hydraulic action and mouthful is opened, and current are discharged.
