Flow Guide Assembly for Water Seal Floor Drain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water seal floor drains experience reduced drainage efficiency due to upward air flows in the drainpipe causing the sealing cover to be frequently lifted or only partially opened, leading to reduced water drainage.
Innovation Solution
A flow guide assembly and water seal floor drain design that includes a guide component with a convex structure to split upward air flows, allowing the sealing cover to open easily and ensuring smooth drainage by reducing pressure from counter-current air flows, featuring a lifting rod and guide component configuration that adjusts to different states for optimal drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat sealing cover is used in a water seal floor drain, then the drainage channel size is increased and drainage efficiency is improved, but upward air flow in the drainpipe frequently lifts the sealing cover or prevents it from opening fully, reducing actual drainage performance
Solution Approach 1:
A guide component is introduced as an intermediary element between the upward air flow and the sealing cover. This guide component redirects the upward air flow away from the sealing cover, preventing it from being lifted or blocked, thereby ensuring reliable opening while maintaining improved drainage efficiency
Solution Approach 2:
The upward air flow, which originally caused harmful effects by lifting the sealing cover or blocking opening, is redirected through the guide component to flow along the inner wall of the drainage channel. This converts the harmful upward flow into a beneficial directional flow that does not interfere with sealing cover operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The guide component effectively splits upward air flows, reducing pressure on the sealing cover and ensuring it can open fully, resulting in improved drainage efficiency and preventing interference with fluid flow.
Implementation Method 1
the guide component effectively splits upward air flows, reducing pressure on the sealing cover and ensuring it can open fully
Implementation Method 2
The lifting rod is configured to slide up and down in the sliding component

AI summary
The present application relates to the technical field of a bathroom equipment, and particularly to a flow guide assembly and water seal floor drain. The water seal floor drain includes a floor drain seat, a floor drain cover, a fixing body, a water seal body assembly, a lifting rod and a sealing cover, in which an upper end of the lifting rod is slidably connected to the water seal body assembly, and an upper end of the sealing cover is rotationally connected at a center to the lifting rod. The flow guide assembly further includes a guide component provided at a side of the sealing cover departing from the lifting rod. A lower surface of the guide component acts as a second guide surface, and is configured to bulge downward. In addition, the present application relates to a flow guide assembly for guiding the flow of a fluid.
