Abstract
The utility model discloses a floor drain pit, comprising a grate cover, a U-shaped bowl and a sealing bowl. The utility model is characterized in that a contact part of the sealing bowl and the U-shaped bowl is a planar structure; the U-shaped bowl is sealed by means of deadweight of the sealing bowl without water; an enclosed space is arranged at the rim of the sealing bowl; the buoyancy generated by the enclosed space enables the sealing bowl to float. The utility model has the advantages that sewage is discharged to fill up the U-shaped bowl and float the sealing bowl, enabling sewage to flow into sewer, while the remaining sewage seals the niff of the sewer; when the sewage is exhausted, the sealing bowl loses floating effect and automatically presses on the U-shaped bowl to seal the niff of the sewer; therefore, the floor drain has the sealing effect regardless of the water.
Description
Technical field
The utility model belongs to building product, relates in particular to floor drain.
Background technology
All design and installation has floor drain on the floor of the kitchen in building room, washroom, and what be used for sewage lets out and prevent the foul smell upper punch down.Traditional floor drain structure is, inverted bowl that seals of button on the U-shaped bowl of an annular seals bowl and goes up rib with the design of U-shaped bowl contact site, the slit that the contact site is maintained leak.Cover a double-edged fine-toothed comb lid again and stop dirt.Its operating principle is, at first fills up the U-shaped bowl when letting out under the sewage, seals the foul smell of sewer with sewage.
The deficiency of this structure is, loses sealing function after sewage is withered, and the sewer foul smell is flushed in the room on still, does not have sealing function.
Summary of the invention
The utility model is to overcome the deficiency of drain structure traditionally, and a kind of floor drain that also can seal foul smell under anhydrous situation is provided.
For achieving the above object, the application's structure is: comprise double-edged fine-toothed comb lid, U-shaped bowl and seal bowl, it is characterized in that:
1, sealing bowl is plane structure with the contact site of U-shaped bowl, seals U-shaped the rim of a bowl by the deadweight of sealing bowl under anhydrous situation.
2, the rim of a bowl that seals bowl has enclosure space, and the buoyancy that enclosure space produces is enough to make and seals a bowl levitating.
Its good effect is: when letting out, fill up behind the U-shaped bowl again that levitating seals bowl under sewage, make sewage flow into sewer, residue sewage is sealed the foul smell of sewer; After sewage is withered, seal bowl and lose floating effect, by being pressed in automatically on U-shaped the rim of a bowl, seal the foul smell of sewer.Can both play sealing function so no matter whether there is water or not.
Description of drawings
Fig. 1 is the sectional view of embodiment of the present utility model.
Among the figure: 1-double-edged fine-toothed comb lid, 2-seals bowl, 3-enclosure space, 4-U shape bowl, 5-gag lever post, 6-limited post, the 7-conical surface.
Arrow is represented water (flow) direction among the figure.
The specific embodiment
The application's embodiment now is described in conjunction with Fig. 1.
As shown in Figure 1, the application comprises double-edged fine-toothed comb lid 1, U-shaped bowl 4 and seals bowl 2, it is characterized in that: the contact site that seals bowl 2 and U-shaped bowl 4 is a plane structure, seals U-shaped the rim of a bowl 4 by the deadweight of sealing bowl 2 under anhydrous situation; Sealing bowl the rim of a bowl of 2 has enclosure space 3, and the buoyancy that enclosure space 3 produces is enough to make and seals bowl 2 levitatings.
For making seal under the low water situation tighter, be processed with limited post 6 in sealing bowl 2, be processed with gag lever post 5 in U-shaped bowl 4, the contact site that seals bowl 2 and U-shaped bowl 4 is processed into the conical surface 7 each other, limited post 6 inserts in the hole of gag lever post 5, guarantees the accurate contact of the conical surface 7.
