The mounting portion and the limiting protrusion cooperate to realize detachable installation of the positioning member and the water inlet portion. The flexible material can be rubber, silicone, plastic or the like, as long as it can deform and fix the cover.

[0016] In the drain shell, the water inlet portion and the cover are square, the positioning member is installed at four corner positions of the water inlet portion, and four corners of the cover are correspondingly installed on the positioning steps of the positioning member.

[0017] The square is a conventional shape of the drain shell. The water inlet portion and the cover of the drain shell can also be rectangular, track-shaped, circular, elliptical or other irregular shapes such as star-shaped, leaf-shaped and cloud-shaped.

[0018] In the drain shell, the middle part of the bottom surface of the water inlet portion is concave to form a circular connecting portion, the lower end of the connecting portion is communicated with the drainage portion, and the diameter of the connecting portion is greater than that of the drainage portion.

[0019] In order to facilitate connection with the drain pipe, the drainage portion is generally in the form of a circular pipe, and the water inlet portion can be in various shapes such as square, rectangular and circular according to actual needs. The connecting portion can play a connecting and transitional role, and the design of the connecting portion also facilitates installation of drain accessories such as drain cores and filter screens.

[0020] In the drain shell, the face cover is provided with a plurality of water passing holes.

[0021] The water passing holes and the water passing gaps can make the drain shell drain faster.

[0022] Compared with the prior art, the technical effects of the utility model are:

[0023] The utility model discloses a positioning member is set up to the face cover and is fixedly clamped to make the face cover can be more firmly installed on the shell, and the water passing gap is set up between the face cover and the inner side wall of the water inlet portion, can also increase the water inlet area, and the overall drainage speed is faster.
