Abstract
The utility model discloses a novel floor drain. The novel floor drain comprises a plurality of expanded bodies which are orderly connected end by end to be annular. The expanded body comprises two layers at the inner side and the outer side, including a water absorbing rubber layer arranged at the outer side and a rubber layer which is arranged at the inner side and which has smaller expansion coefficient than the water absorbing rubber layer. The novel floor drain designed according to the structure proposal of the utility model has the advantages of simple structure and convenient usage, can obstruct smell from spreading and also can prevent the pest such as mosquito etc. from entering home.
Description
Technical field
The utility model relates to a kind of novel floor drain, can close automatically and open when dry and moist.
Background technology
Summer, have often one unpleasant peculiar smell from the washroom or the floor drain of balcony come out, sometimes in mosquito that sewer grows and multiplies and other unknown little insect also can be got home by floor drain, with we " intimate contact ".So I have expected designing such floor drain: when we need draining, can open the structure that floor drain then sealed automatically when ground did not have ponding or need not draining automatically.Can stop distributing of stink like this, can prevent that again insect such as mosquito from entering at home, make life at home more comfortable.
The utility model content
Goal of the invention of the present utility model is for a kind of novel floor drain being provided, can closing automatically and open when dry and moist.Distribute bad smell and allow mosquito enter problem in the family to solve existing floor drain.
Goal of the invention of the present utility model can be achieved through the following technical solutions.
A kind of novel floor drain, it includes the expander that some head and the tail are connected to annular successively, and described expander comprises inboard and the outside is two-layer: be arranged at the water sucting rubber layer in the outside and be arranged at the inboard coefficient of expansion rubber layer little than the water sucting rubber layer.
Described expander is that two lobe kidney shapes join end to end.
When water is arranged, the material imbibition, because outside dilation ratio inboard big (water swelling rubber that the material outside available rates is moderate, common rubber can be adopted in the inboard) forms a duct so can arch upward, water just can enter smoothly.And when dry, the material dehydration is restored, and the duct is sealed automatically.
Novel floor drain by the utility model Scheme design forms has advantage simple in structure, easy to use, can stop distributing of stink, can prevent that again insect such as mosquito from entering at home.

Structural representation when Fig. 1 closes for the utility model;
Structural representation when Fig. 2 opens for the utility model.
Among the figure: 1-expander 2-water swelling rubber layer 3-rubber layer
The specific embodiment
Further specify design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, a kind of novel floor drain, it includes the expander 1 that some head and the tail are connected to annular successively, and it is inboard and the outside is two-layer that described expander 1 comprises: be arranged at the water sucting rubber layer 2 in the outside and be arranged at the inboard coefficient of expansion rubber layer 3 little than water sucting rubber layer 2.
As depicted in figs. 1 and 2, when water was arranged, expander 1 imbibition because the dilation of the water sucting rubber layer in the outside is bigger than inboard rubber layer, thereby can be arched upward, and forms a duct, and water just can enter smoothly.And when dry, expander 1 dehydration is restored, and the duct is sealed automatically.
