Background technology

For the waste water that will remain in indoor or the container (as bathroom, washroom, kitchen, scrub container etc.) enters sewer, people have installed the floor drain of being convenient to draining in the joint portion of sewer pipe and flooring or container bottom.The use of floor drain can prevent sewer pipe obstruction, make things convenient for draining, can also beautify the environment.Indoor for preventing in the sewer pipe that peculiar smell returns building, the floor drain that uses is to install a convex cover cap at an upper portion thereof additional now, when promptly installing, earlier the convex cover cap is covered on the gutter road junction, again the draining grid lid of floor drain is placed the convex cover cap on and concordant in ground.Waste water flows to downwards on the convex cover cap by the hole of draining grid lid, again by entering sewer pipe around the convex cover cap.When the peculiar smell in the sewer pipe upwards volatilizees, run into the obstruct of convex cover cap, so can not be dispersed into indoor next.But the floor drain of this structure just adopts once simply obstruct for the peculiar smell in the sewer pipe, because of water proof very little, local leak is during near the water yield is big down sewer pipe, and because of the pressure that descends water generates is big, the foul smell in the sewer pipe often is flushed to ground and does not have the deodorization effect.Even some design convex cover cap has with a certain distance from the residual water surface of deodorization, or deodorization residual water volatilization and do not have odor-resistant result in the short time, is difficult to be fit to the needs of people's modernization life.

The utility model content

The purpose of this utility model is the technical problem that will solve existing floor drain odor-resistant result difference, proposes a kind of thorough solution deodorization problem, floor drain simple in structure.

For addressing the above problem, the technical solution of the utility model is a kind of odour-proof floor drain of structure, it comprises the sewer cover that has following boom plate, be connected in the following water conduit below the described sewer cover, described water conduit free end down also is provided with one to recessed deodorisation cover, this deodorisation cover is the open end near an end (upper end) of described sewer cover, the internal face of described deodorisation cover and the described outside wall surface of water conduit down leave drainage gap, described the inner chamber free end (lower end) and described drainage gap conducting of water conduit down.

Described sewer cover can be rectangle or circle.

Described boom plate down can be to flexibly connect with being connected of described sewer cover.

Described water conduit down can be cylindrical, and described deodorisation cover is the flat cylindrical deodorisation cover of internal diameter greater than water conduit external diameter under described, and the described circumference wall of water conduit free end (lower end) down is provided with through hole.

Described deodorisation cover and described down water conduit be free-ended to be connected to and to flexibly connect or fixedly connected.

The utility model is provided with the deodorisation cover of a downward spill in the following water conduit lower end of floor drain, the upper end of this deodorisation cover is the open end, water supply and draining is used, leave circumferential drainage gap between following water conduit and the deodorisation cover, the inner chamber lower end of descending water conduit in addition is by perforate or fluting and described drainage gap conducting; During the floor drain draining, waste water flows into the inner chamber of water conduit down by the following drain hole of boom plate, and the open end of upwards turning back again by deodorisation cover through drainage gap enters sewer.After waste water was discharged by deodorisation cover upper end, the water level of residual certain altitude also in described drainage gap and the following water conduit can play the effect of water seal.So, peculiar smell in the sewer pipe must can realize that if want in the return chamber the utility model adopts labyrinth seal and water-seal principle along the opposite path of draining, can prevent effectively that the peculiar smell in the sewer pipe from distributing to indoor, thus good air ambient in the holding chamber; In addition, drain structure is simple, draining is unobstructed, be convenient to maintenance.
