Abstract

The invention relates to a float type floor drain comprising a pipe head of a sewer, a draining grid and a floater on the internal seam of the pipe head. The floor drain is characterized in that the lower end of a floater extends into a cover; the cover of the floater and the internal seam form a water sealing; and the upper part of the floater is column-shaped and matched with the guide rail of the lower end of the draining grid; therefore, the floater can float up and down in a certain range for improving the drainage capacity. Compared with the prior art, the floor drain has the characteristic of being difficult to block, and especially has the advantages of good deodorization effect, convenience for use and large drainage discharge.

Description

A kind of floor drain

Affiliated technical field

The present invention relates to a kind of plumbing installation of waste water, specifically, be a kind of mainly be the floater type floor drain that prevents foul smell diffusion.。

Background technology

Industry at present, the sewer floor drain of civilian construction has multiple structure, as hydrolock, turnover plate type, floater type floor drain, wherein, the parts of hydrolock floor drain all are to adopt cast iron materials to make, often cause dirt to stop up the water seal hole, cause floor drain not leak, and turning plate type floor drain often results in blockage owing to dirt winding rotating plate shaft or is inoperative, the characteristics of floater type floor drain are to be difficult for stopping up, but its weak point is arranged also, a kind of " float-ball type sewer floor drain " disclosed as Chinese patent (application number 90202559.2), it mainly is made up of leak grate and seal member, its seal member specifically is made of ball float dish and ball float, ball float dish cylinder inserts in the sewer vertical tube, ball float is pressed and is crouched on the ball float center hole, its purpose is to provide a kind of difficult obstruction, and can prevent the novel floor drain of string contaminated environment on the dirty gas of sewer, its weak point is in fact only to be the simple seal of the female end of ball float and sewer tube head, residue in the gap that the dirt of female end causes ball float and female end, odor-resistant result is poor; In addition, need raise grate earlier during the cleaning sewer pipe, take out ball float again, use also not very convenient.

Summary of the invention

The objective of the invention is to provides a kind of difficult obstruction at above-mentioned deficiency of the prior art, and it is good to have odor-resistant result especially, in addition, also has the novel floor drain of characteristics easy to use, that displacement is big.

The objective of the invention is to realize with following technical scheme: it includes the sewer tube head, the float on the female end of leak grate and tube head, its key is that the button cover is extended in the bottom of float, the button cover of float and female end form water seal, and the top of float is column, guide rail with the grate bottom that leaks, make float according to coming the water yield to fluctuate within the specific limits, strengthened drainability.Specifically, the top of float is circular-arc, the hollow cylinder that one top seal is arranged at the top, the grate bottom that leaks have a guide rail that can entangle hollow cylinder, extend the button cover in the bottom of float, float be the thin-walled body that constitutes by light material, in addition, extended button shroud rim is a dentation in the bottom of float, and this tooth-like part of anything is immersed in all the time in the water of female end and forms water seal, this dentalation is in order to reduce the resistance that water flows, to have strengthened displacement comparatively speaking.

Fig. 1 is a cross-sectional schematic of the present invention.

Fig. 2 is the schematic diagram of float among the present invention.

The invention will be further described below in conjunction with drawings and Examples.

It includes sewer tube head 5, the float 4 on the female end 6 of leak grate 1 and tube head, said float 4 can be multiple shape, its key is that the button cover is extended in its underpart, thereby make the button cover of float 4 and female end 6 form water seal, and the top of float 4 is 3 of column, with guide rail 2 couplings of grate 1 bottom that leaks.Thereby can overcome the shortcoming of the odor-resistant result difference that causes owing to simple seal in the prior art substantially.What further optimize is that the button shroud rim that float 4 extends is a dentation, and this dentalation is in order to reduce the resistance that water flows, to have strengthened displacement comparatively speaking, can prevent the indoor ponding incident that reason such as antipriming pipe explosion causes to a certain extent.

Certainly, the present invention is not limited to the embodiment that the front is introduced, and we can replace whole device with another kind of equivalent arrangements, and do not exceed scope of the present invention.

Claims

1. floor drain includes sewer tube head 5, the float 4 on the female end 6 of leak grate 1 and tube head, it is characterized in that, the button cover is extended in the bottom of float 4, the button cover of float 4 and female end 6 forms water seals, and the top of float 4 is 3 of column, with guide rail 2 couplings of grate 1 bottom that leaks.

2. a kind of floor drain according to claim 1 is characterized in that, it is dentalation that the button shroud rim is extended in the bottom of float 4.
