Wave-fold split type floor drain core

Abstract

The invention discloses a wave-fold split type floor drain core which is mainly composed of a wave-fold outer shell and a flow guiding filtering pipe. A narrow slit annular flow channel of a traditional floor drain can be changed into a triangular water flowing channel. After water flow enters a wave-fold water storage bottle through a water inlet (an A area), the water flow is overflowed from an upper opening (a B area) of the water storage bottle and then enters a water drain pipe (a C area) of a building. The B area and the C area are triangular water drain cross sections, the flow velocity gradient can be effectively improved, water in a water collection area rapidly passes through the wave-fold split type floor drain core to flow into the water drain pipe, and meanwhile the wave-fold split type floor drain core is detachable and convenient to install, replace and clear. When an existing floor drain is transformed under the premise that existing floor decoration is not damaged, the water storage bottle of the wave-fold outer shell is made of elastic plastic or rubber materials, and the water storage bottle can be shrunk along the axis under the effect of gripping force and can be conveniently placed into the water drain pipe of the building from an opening of the existing floor drain. When the floor drain is newly installed or overall replaced, the wave-fold outer shell, the opening of the floor drain and a panel of the floor drain can be designed to be a whole. The wave-fold split type floor drain core belongs to the technical field of sanitary ware.

Description

Technical field: [0001] The "wave-folding split-type floor drain core" proposed by the present invention is a device for connecting a floor water collection port to a drainage pipe network, and belongs to the technical field of sanitary ware. technical background: [0002] At present, the floor drains widely used in daily life are "bell jar (button bowl) floor drains". This type of floor drain has a long history of use. One is that the water flow channel is a narrow slit annular flow channel, the water flow is slow, and it is easy to silt up; the second disadvantage is that the water seal is relatively shallow, and the water seal is easily damaged due to the unbalanced pressure of the pipeline. If the floor drain is not replenished with water every few days, the water The seal will also be damaged due to water evaporation, and harmful gases in the pipeline can easily enter the room, causing environmental pollution. The national standard "Code for Design of Building Water Su...

AI Technical Summary

Problems solved by technology

Most of the installed floor drain cores are to separate the diameter of the original floor drain into a drainage pipe and a water storage area, which reduces the actual drainage pipe diameter and increases the drainage resistance, so the practicality is not high; the mechanical plugging type , There are V-shaped self-closing type, gravity mechanical type, artificial spring type, magnet type, etc. This type of floor drain is easily affected by debris in the water and deformation of the sealing ring, resulting in poor airtightness.
