Referring to Fig. 1, use commonplace drain structure at present as shown in Figure 1.Top at the floor drain cavity 2 of cylindrical shape is coated with "T"-shaped drain cover 1, and the downside of this drain cover 1 is provided with dash annulus 11, and this dash annulus 11 is separated into inside and outside two ring-shaped cavities with floor drain cavity 2.When the circular grid hole 12 of sewage by the outside, drain cover 1 end flows in the floor drain cavity 2, flowed into before this in the outer shroud cavity wherein, the dash annulus 11 that must walk around drain cover 1 downside just can enter ring cavity body in it, and then interfluent gutter 21, flows into sewer again.This floor drain apparatus forms " U " shape drainage channel with dash annulus 11 in floor drain cavity 2, and utilizes remaining water formation water seal in the floor drain cavity 2, stops the peculiar smell in the sewer to overflow by floor drain.But, in floor drain cavity 2 remaining water dry after, water seal can't form, the peculiar smell in the sewer is with regard to overflowing by floor drain very naturally in the inlet chamber, contaminated air.In summer, because frequent bathing, always there are a large amount of ponding " U " type pipe bottom of floor drain, and this phenomenon also can usually not take place.But in other three seasons, if " U " of floor drain still can not form water seal though type pipe bottom does not have ponding or ponding is arranged, the excessive phenomenon of the peculiar smell of sewer just is difficult to avoid.

For this defective of drain structure, not only ubiquity in various existing houses also causes many owners and real estate developer's contradiction and quarrel in some newly-built dwelling houses.Especially after the epidemic disease wildness of SARS (Severe Acute Respiratory Syndrome) SARS, people are more urgent for the demand of fresh air, require the hope of transformation drain structure defective more sincere and strong.

Summary of the invention

The purpose of this utility model provides the floor drain of a kind of novel structure, practicality, and this floor drain can avoid the peculiar smell in the sewer excessive when guaranteeing draining-off sewage effectively, keeps room air not contaminated, improves the life grade.

The purpose of this utility model is achieved in that a kind of floor drain, is made up of the floor drain cavity of cylindrical shape and the "T"-shaped drain cover that covers on its top, is provided with gutter in the middle of the described floor drain cavity, and this gutter stretches into sewer and is communicated with it; The outside, described drain cover end is provided with circular grid hole, as the drainage inlet through hole; Downside is provided with the dash annulus, and this dash annulus is separated into inside and outside two ring-shaped cavities with the floor drain cavity; It is characterized in that: also include the movable floating head that is used to hide gutter top through hole.

Described movable floating head is that the top is a dome, middle for connecting rod, bottom are the float member of torus shape, is placed in the cavity between the gutter of the dash annulus of drain cover downside and floor drain cavity.

The buoyancy aid of the torus shape of described movable floating head bottom is a hollow.

Connecting rod quantity in the middle of the described movable floating head is 2～4.

Described movable floating head is the integral member of injection mo(u)lding, and its material is ABS engineering plastics or PVC plastics.

The utility model is a kind of floor drain, in the cavity between the gutter of the dash annulus of drain cover downside and floor drain cavity, have additional a top and be dome, middle for connecting rod, bottom be the float member-movable floating head of torus shape.When the locality was omitted water in printing, this activity floating head made the water of floor drain cavity normally to excrete out from gutter owing to the buoyancy of water in the floor drain cavity floats.When the more formation water seal of remaining water in " U " shape drainage channel in the floor drain cavity, this device can stop the peculiar smell in the sewer to overflow by floor drain in the same old way.But, remaining water is less or dry and can't form water seal the time in floor drain cavity 2, this activity floating head also can drop on the sewer top by its deadweight in default of its come-up of buoyancy of water holder, the dome at its top covers sewer top through hole just, has stoped the peculiar smell of sewer outwards to overflow.This apparatus structure novelty, simple, practical, easy to manufacture, with low cost has extraordinary application prospect.
