Abstract

A floor drain against counter-flow and stinking comprises a drain casing having an inner pipe, an ating grid covering on upper portion of the drain casing and a phosphorizer type floating drum suspending covered on the inner pipe of the casing. The phosphorizer type floating drum is supported on the inner pipe of the casing by an inner reinforced plate of the inner top thereof. A long protrusion passing through a central hole of the ating grid is provided on upper portion of the floating drum to locate the floating drum. A water seal having anti-stinking function is formed between the drain casing and the inner pipe. When downcast pipe is blocked, the floating drum floats upwards to seal a water outlet formed by a seal ring on upper end of the drain, thus sewage overflowing outside is prevented and counter-flow function is achieved.

Description

The anti-spill-out odour-proof floor drain

Affiliated technical field

The utility model relates to the draining floor drain, particularly a kind of floor drain with deodorization and anti-spill-out function.

Background technology

At present, the floor drain that effluent discharge is used in civilian construction, be to be buckled with a movable bell jar at the top of floor drain housing, the top of movable bell jar is a plane operator, its bell jar that connects below is suspended in above the interior pipe of floor drain housing, forms water seal like this between the interior pipe of floor drain housing and housing, and sewage enters the back from grate and enters water seal from the bell jar periphery, enter sewer pipe again, the deodorization effect is played in water seal like this.In addition, be useful on the floor drain of trough urinal, the grate on its movable bell jar top is done camber.

But these floor drains all do not possess the anti-spill-out function at present, in case following drainage pipe somewhere is stopped up, sewage will bring a lot of inconvenience to live and work by the grate overflow to ground.

Summary of the invention

The purpose of this utility model is at above-mentioned deficiency, provides a kind of deodorant function that both had, the novel floor drain that has the anti-spill-out function again.

The technical scheme that its technical problem that solves the utility model adopts is: this novel floor drain is made up of the floor drain housing of pipe in the band and the grate that is buckled in the floor drain case top, floor drain housing and the interior pipe in it are connected as a single entity, and the floor drain lower housing portion is buckled on the sewer pipe.Bell shape floating drum of outstanding button above the pipe in the housing.Between the pipe support mechanism supports is arranged in bell shape floating drum and the housing, concave station is arranged at inner walls top, between concave station and the top grate sealing ring is housed, and forms a following mouth of a river, and spar diameter is greater than following mouth of a river diameter.For ease of the location of bell shape floating drum, bell shape floating drum top is provided with a long projection, and passes the grate centre bore.

The beneficial effects of the utility model are: this novel floor drain is buckled on the interior pipe of floor drain housing by the bell shape floating drum is outstanding, thereby has formed water seal between pipe and the housing in housing, thereby has played the function of deodorization.Simultaneously, the bell shape floating drum is owing to be outstanding being buckled in above the interior pipe of housing, and because the positioning action of the long projection in its top, when sewer pipe a part was stopped up, the sewage overflow just can be moved on the jacking bell shape floating drum, on when moving to down the mouth of a river, just can will descend the mouth of a river to shut, thereby prevented sewage outflow, and then taken measures to clear up line clogging, provide convenience to daily life.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

As shown in drawings, grate 3 is fixed on the floor drain housing 6 by screw 4, between the concave station 12 on grate 3 and the inner walls sealing ring 5 is housed, thereby forms the following mouth of a river 11 below the grate 3.Floor drain housing 6 has interior pipe 9 and is connected as a single entity, and just can form water seal between pipe and the housing in it.

In the outstanding bell shape floating drums 7 that are buckled with above the pipe 9, it is arranged at a plurality of inner reinforced plates 10 bell shape floating drum 7 inner tops and that be connected as a single entity with it with support mechanism between the interior pipe, manages 9 top in being supported in.(the also available herein cross bracket that is connected with the floating drum inwall places the top of interior pipe 9 to play a supportive role.) recessed 13 of the length at its top that bell shape floating drum 7 is played the role of positioning, pass the centre bore of grate 3, its top is fixed with screw 1, is pressed with packing ring 2 below the screw 1, and it passes the grate center and a little more than grate 3.Its effect is to catch herein to mention floating drum, clears up the dirt at long projection of floating drum and grate hole place, and dirt is stuck herein for quilt when preventing the floating drum come-up.

The floor drain bottom communicates with sewer pipe 8, and during normal draining, sewage is flowed down by grate 3 mider holes, between bell shape floating drum 7 outer walls and housing 6 inwalls, enters via floating drum inwall and outer wall of inner tube that intracardiac pipe enters following sewer pipe in the floor drain again.

Water is arranged in the floor drain all the time, and the depth of water is managed upper end in floor drain, forms water seal, and deodorant function is arranged.When sewer pipe stopped up, sewage overflow jacking floating drum, sealing ring blocked the floating drum come-up and also seal the excessive of sewage.
