Floor drain with automatic blocking/drainage device

Abstract

The invention relates to a floor drain, in particular to a floor drain with an automatic blocking / drainage device, the floor drain can automatically open or block the mouth of a downpipe at any time so as to prevent the occurrence of ground water impoundment and indoor air pollution by using a special mechanism when the floor drain is used or not used. The floor drain comprises a floor drain body, a floor drain cover, an inner core, a floating body cover and a reducing downpipe, wherein the floor drain cover is covered on the floor drain body, and fixed by a fastening pin; the inner core is sleeved on the reducing downpipe, and can move upwards and downwards by a handle; and the floating body cover is arranged on the inner core and the downpipe, once being used, the floating body cover can achieve a water-seal / cover-seal double sealing effect. When the dirt deposited on the bottom of the floor drain is removed, the removing of the dirt can be realized only by lifting the inner core to flush with water, and the process of removing is simple and quick.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain with an automatic blocking and draining device for discharging indoor ground and accumulated water on the floor of a shower room. Background technique [0002] When washing the ground with water or taking a shower in the shower room, a floor drain is required to discharge the accumulated water. But because the terminal of the downpipe under the floor drain is included in the septic tank or the sewer, the outfall of the floor drain has the problem of leaking harmful gases from the downpipe, the septic tank, and the sewer. The prevention method that people adopt at present is generally that a section of U-shaped pipe is set in the downpipe under the floor drain to sit on water, or a buckle bowl water seal is set inside the floor drain to prevent harmful gas from leaking upwards. These methods are not very effective, such as sitting on water in a bend and sealing a bowl with water. Th...
