Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
The stereogram after large discharge odour-proof floor drain partly cut-away is shown with reference to figure 1, Fig. 1.As shown in Figure 1, the drain cover 2 that this large discharge odour-proof floor drain comprises floor drain seat 5 and is fastened on floor drain seat 5, drain cover 2 is provided with water hole 1; Floor drain seat 2 is provided with to lower convexity, in hemispheric screen pack 8 at the edge of neighboringly Cancellation Missed installation position; The mesh size of screen pack 8 is less than the size of water hole 1.
When sewage is by drain cover 2, can stop foreign material larger inside sewage and hair; Through screen pack 8 can to sewage in the less further filtering of foreign material; When a large amount of sewage discharged by indoor needs, can removably Cancellation Missed 2, filter to increase discharge area, the stop of foreign material can be realized again simultaneously.
Drain cover 2 is connected with the external surface of floor drain seat 5 by hinge 9; After arranging like this, even if do not use drain cover 2 for a long time, do not worry that drain cover 2 is lost yet.
