The content of the invention

The purpose of the present invention is there are the problems referred to above for existing technology, it is proposed that a kind of water outlet is smooth, sealing is stable Odour-proof floor drain.

The purpose of the present invention can be realized by following technical proposal：A kind of odour-proof floor drain, including outer cylinder body, with water inlet The inner barrel and the panel above inner barrel of mouth and outlet, is provided with sealing plate in the inner core body, it is characterised in that The sealing plate is in dish and is located at water outlet, and sealing plate edge portion is coated with sealing member, and the sealing member includes cutting The sealing that the circular body and autonomous agent that face takes the shape of the letter U stretches out, the sealing of the sealing member are resisted against going out for inner barrel At the mouth of a river.

The odour-proof floor drain of this structure, by being coated with sealing member in sealing plate, using in sealing member and inner barrel Side wall leans to realize sealing outlet.And inner barrel medial wall itself is not connected with any sealing member, in the inner core body Outlet size on wall can't reduce, and the relative aperture of whole outlet is larger, and corresponding displacement also than larger, can guarantee that Water outlet is smooth.In addition the sealing member is coated on outside sealing plate, whole elastically-deformable loaded area than larger, even if sealing Plate produces fraction of skew in the presence of hydraulic pressure, sealing member and inner barrel medial wall effective contact can be also effectively ensured, enters one Step ensures sealing.Here sealing plate plays the effect of integrated support, and sealing member then gives certain elastic deformation space, i.e., Make on sealing plate outer surface, have a little hollow or out-of-flatness, can effectively be offset after sealing member is squeezed, prevent smelly Gas or sewage are passed through from gap, can make sealing plate sealing it is safe and reliable, effectively prevent foul smell excessive.

In above-mentioned odour-proof floor drain, the sealing is annular in shape and sealing is resisted against at the lower port of inner barrel.

The sealing of ring-type ensure that the inner barrel with annular is more effectively coordinated, and in this programme, inner core The lower port of body directly serves as outlet, is leant the sealing that can just be directly realized by by sealing and inner barrel lower port.Certainly The external diameter of sealing now is greater than inner barrel internal diameter and could realize sealing.When in the state of stress is little sealing with it is interior Cylinder lower port fits and realizes sealing, and when under the larger state of stress, sealing can produce deformation in the presence of inner barrel, It is brought into close contact with inner barrel after shallow decline.
