The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, by improvement to existing odour-proof floor drain structure, provided a kind of novel family expenses odour-proof floor drain, this family expenses odour-proof floor drain makes full use of existing cast iron floor drain, and increased the capping of a float-ball type, have simple in structurely, easy to operate and odor-resistant result reliable characteristics has solved the problem that indoor sewer pipe stopped up and prevented to return flavor.

The technical scheme that the utility model provides is: this family expenses odour-proof floor drain includes the floor drain and the capping of band trap, wherein said capping is buckled on the floor drain, be characterized in that described capping is the ball float of a hollow, the top of this float-ball type capping is that hemisphere, the middle part of umbrella is that inverted Rotary-table, bottom are the cone of section, the inverted round table body at described float-ball type capping middle part is provided with the sealed circular ring to lower convexity, and the cone section place of described float-ball type capping bottom is connected with a backstay.

In the utility model, the float-ball type capping should be able to freely be risen and fallen with the height of the water accumulation level in the indoor kitchen sink sewer and be positioned at exactly on the mouth of pipe of sewer.Therefore under the prerequisite that float can be floating during ponding in guaranteeing sink, allow the shaped design of float-ball type capping is become multiple style, as spherical, truncated cone-shaped or taper shape etc.The effect of sealed circular ring is to be used for inserting in the water seal of the floor drain water crook of indoor kitchen sink sewer, also can not return flavor from here even guarantee that the ponding of water seal place dries up after doing.The effect of backstay is the dislocation that prevents that the floating back of float-ball type capping from producing, so its length should be decided according to the floating maximum height of the institute of float-ball type capping behind indoor kitchen sink sewer ponding energy.

Compared with prior art, the beneficial effects of the utility model are to make full use of existing cast iron floor drain, and have increased the capping of a float-ball type, have simple in structure, easy to operate and odor-resistant result reliable characteristics has solved the problem that indoor sewer pipe stopped up and prevented to return flavor.

Description of drawings

Accompanying drawing is the structural representation that the utility model provides embodiment.

The specific embodiment

As shown in the figure, this family expenses odour-proof floor drain includes the floor drain 1 and the capping 3 of band trap 2, wherein said capping 3 is buckled on the floor drain 2, described capping 3 is the ball float of a hollow, the top of this float-ball type capping 3 is that hemisphere, the middle part of umbrella is that inverted Rotary-table, bottom are the cone of section, the inverted round table body at described float-ball type capping 3 middle parts is provided with the sealed circular ring 4 to lower convexity, and the cone section place of described float-ball type capping 3 bottoms is connected with a backstay 5.

Operating principle of the present utility model is as follows:

When not toward kitchen sink sewer pouring, the cone of float-ball type capping 3 partly is positioned on the sewer mouth of pipe, in the water seal of the trap 2 of the sealed circular ring 4 insertion floor drains 1 on the inverted round table body at float-ball type capping 3 middle parts, therefore the stink in the sewer is tightly sealed.When pouring, the wash water that includes foreign material can cause the obstruction of moment of kitchen sink sewer, and this moment, water level rose, and float-ball type capping 3 is subjected to buoyancy and upwards floating, exposes the mouth of pipe of sewer, and sewage and field trash thereof just can flow into sewer.When stopping pouring, drawdown, buoyancy reduces, and float-ball type capping 3 is fallen immediately, relies on the effect of the backstay 5 of its bottom, causes float-ball type capping 3 accurately to be located, and guarantees to seal tight.
