Description

Floor drain with double trap

Technical field:

The utility model relates to the technical field of drainage and sewer, in particular to a floor drain with double traps.

Background technique:

In the prior art, the floor drain is a connector that connects the ground and the drainage pipeline system through which domestic sewage flows into the drainage pipeline. Therefore, the requirements for the floor drain are: smooth drainage, and the ability to prevent back odor and insect pests. Existing floor drains are limited by the height of the floor finish and the size of the drainpipe. Smooth drainage and anti-return odor cannot achieve both. Either the drainage is slow and clogged, or the deodorization and anti-odor are not done well. It is a sewer technology. a problem to be solved.

Utility model content:

The purpose of the utility model is to provide a floor drain with double traps that can not only drain water smoothly, but also prevent back odor and insects.

The purpose of this utility model is achieved by the following measures: a floor drain with double traps has a housing and an upper cover. It is characterized in that the housing is concave, and the concave upper opening is provided with a The bearing platform corresponding to the shaft shoulder, the center of the concave shape is the drainage outlet, and there is a partition rib between the concave bearing platform and the drainage outlet, and the partition rib divides the concave shape into an outer groove and an inner groove. The upper edge of the drain outlet is lowered successively in the direction of the shell axis, the outer cylindrical surface of the upper cover is provided with several gaps, the lower end surface of the upper cover is provided with a shaft shoulder and the center line of the outer groove and inner groove corresponding to the shell is provided with Outer ribs, inner ribs, the upper cover rests on the concave bearing platform of the shell through the shoulder of the lower end surface, the gap on the outer edge of the upper cover and the gap with the concave inner wall of the shell form the water inlet, the outer ribs of the upper cover and the shell The external groove forms an external water bend, and the inner rib of the upper cover and the inner groove of the shell form an internal water bend.

Compared with the prior art, the floor drain with double traps proposed by the utility model has the following advantages: 1) The outlet of the floor drain directly enters the drainage pipe, and the diameter is large enough to ensure smooth drainage; 2) The floor drain is equipped with internal and external double traps. The water trap has good effects of preventing back odor and insect pests; 3) The upper cover is only placed on the casing, and it is very convenient to cover and remove for cleaning. The utility model has the advantages of novel, compact and reasonable structure, low production cost, easy and convenient installation, and can be popularized and used.

Description of drawings:

Fig. 1 is a structural schematic diagram of an embodiment of the utility model.

Fig. 2 is a top view of the embodiment in Fig. 1 .

Detailed ways:

The specific implementation will be described in detail below in conjunction with the accompanying drawings:

Fig. 1～Fig. 2 has provided the structural schematic diagram of the embodiment of the utility model. In the figure, a floor drain with double traps has a housing 1 and an upper cover 2. The housing 1 is concave, and the concave upper opening is provided with a platform 11 corresponding to the shoulder of the lower end surface of the upper cover 2. The center of the concave shape is a water outlet 12, and a partition rib 13 is arranged between the concave shape platform 11 and the water outlet 12. The partition rib divides the concave shape into an outer groove 14 and an inner groove 15. The upper edge of the drain port 12 is lowered sequentially in the axial direction of the housing 1. The outer cylindrical surface of the upper cover 2 is provided with a number of gaps 21, and the lower end surface of the upper cover 2 is provided with a shaft shoulder and an outer groove 14 corresponding to the housing 1. 1. The center line of the inner groove 15 is provided with an outer rib 24 and an inner rib 25. The upper cover 2 rests on the concave bearing platform 11 of the housing 1 through the shoulder of the lower end surface. The gap of the concave inner wall of the housing 1 forms a water inlet, the outer rib 24 of the upper cover 2 and the outer groove 14 of the housing form an outer water trap, and the inner rib 25 of the upper cover 2 and the inner groove 15 of the housing 1 form an inner water bend.

The utility model works like this: the floor drain is lower than the floor of the kitchen or bathroom, and when the domestic sewage is discharged, it flows into the floor drain through the gap formed by the gap on the outer edge of the upper cover and the gap between the concave inner wall of the housing. The gap is not large, so the larger-sized dirt is discharged out of the floor drain, and the domestic sewage enters the external water trap and overflows into the internal water trap, and then overflows into the drain pipe through the drain outlet, because the cross-sectional size of the flow channel is guaranteed in the design , so the water flows smoothly; secondly, because the shell cap, the upper edge of the partition rib, and the upper edge of the drain are lowered in the direction of the shell axis in turn, so the inner and outer water traps form water seals, which can effectively prevent back odor and prevent pests . The upper cover of this product covers the shell, and it is very convenient to remove and clean.

The above-mentioned embodiments do not constitute a limitation to the present utility model, and all technical solutions obtained in the form of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
