Water draining device with filtering function

Abstract

The invention discloses a water draining device with a filtering function. The water draining device comprises a water drain, a first filtering device and a second filtering device, wherein a first arc-shaped sheet and a second arc-shaped sheet are successively arranged on an inner wall of the water drain; four notches are symmetrically formed in the surface of the first arc-shaped sheet; the first filtering device comprises a first circular fixing block; four first clamping blocks are arranged on the side wall of the first circular fixing block; a filtering screen bag is connected with the bottom of the first circular fixing block; four rotating rods are arranged on the surface of the first circular fixing block; the second filtering device comprises a second circular fixing block; four second clamping blocks are arranged on the side wall of the second circular fixing block; a filtering box is fixedly connected with the bottom of the second circular fixing block. The water draining device is simple and reasonable in structure design, is convenient in operation, is capable of realizing the fixing for the filtering device, is capable of preventing the filtering efficiency from beinginfluenced by the shaking of the filtering screen when the sewage flows by, is capable of preventing the water drain from a non-filtering state and is convenient for taking in and out the first filtering device and the second filtering device.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a drainage device with a filtering function. Background technique [0002] The drainage device is mainly installed in the bathtub or the sink. It is an important interface connecting the drainage pipe and the indoor water. As an important part of the drainage system in the residence, it is very important to the indoor environment. [0003] The drainage device in the prior art mainly includes a water drain and a filter screen arranged in the water drain. The filter screen is simply placed in the water drain. When the sewage flows through, it is easy to cause the filter screen to shake and thus affect the filtration efficiency. When it needs to be cleaned, the water leak is in a non-filtered state, which affects the subsequent continuous use, and it is inconvenient to take the filter device in the prior art.
