Solution Overview
Problem
Existing toilet odor removal systems are cumbersome, require modifications to the toilet and bathroom, are inefficient with low tap water pressure, and lack adaptability for water-saving toilets and scenarios with insufficient tap water pressure.
Innovation Solution
A flush valve system incorporating a linear control water drainage mechanism and a hydraulic water drainage mechanism, with a central partition plate having through holes to control water flow, a venting pipe with a waterproof spiral staircase, and an odor removal device using a high-pressure ozone ceramic medium and catalyst-coated mesh plate to effectively eliminate odors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a hydraulic switch activates both flush valve and inlet valve using tap water pressure, then odor removal is achieved, but the inlet filter blocks after one to two years decreasing water pressure and flush capability
Solution Approach 1:
The system separates the odor removal function from the flushing function. The odor removal uses a dedicated pump that draws water from the tank bottom, while flushing uses a separate inlet valve controlled by a float mechanism. This segmentation prevents the inlet filter from blocking the odor removal pump, maintaining reliable operation of both functions independently.
Solution Approach 2:
The patent introduces a second pump as an intermediary device specifically for odor removal. This pump draws water from the bottom of the tank through a separate pathway, bypassing the inlet filter that blocks the main flushing system. The intermediary pump ensures odor removal continues to work even when the main inlet filter is blocked.
2Object-generated harmful factors
If the flush valve is activated by tap water pressure, then odor removal is achieved, but the amount of water per flushing is subject to water pressure variation compromising water saving
Solution Approach 1:
The system uses a float mechanism that provides feedback-based control for the inlet valve. When the water level in the tank reaches a predetermined height, the float automatically closes the inlet valve, preventing overfilling. This feedback control ensures precise water usage for flushing, making the system water-saving and independent of tap water pressure variations.
Solution Approach 2:
The flushing system is designed to be self-regulating through the float mechanism. The system automatically controls the inlet valve based on water level, and the pump automatically activates when odor is detected, eliminating the need for external pressure control and achieving water-saving operation.
3Object-generated harmful factors
If the device uses excessive components for odor removal and flushing, then odor removal capability is enhanced, but installation becomes difficult
Solution Approach 1:
The system uses a multi-functional pump that serves both odor removal and flushing functions. The same pump can draw water for odor removal or for refilling the tank after flushing, reducing the total number of components needed. This universality simplifies installation while maintaining effective odor removal capability.
4Loss of substance
If water stored in the toilet tank cannot be used for flushing when tap water supply is cut off, then water saving is achieved, but flushing cannot be implemented when no tap water pressure
Solution Approach 1:
The system automatically manages water from the tank for both odor removal and flushing operations. The pump draws water from the tank bottom for odor removal, and the float-controlled inlet valve refills the tank after flushing. This self-service mechanism ensures flushing can be implemented using stored tank water even when tap water supply is cut off, maintaining ease of operation while achieving water saving.

AI summary
Disclosed is an improved dual control mode-type deodorising and water drainage valve. The water drainage valve comprises a linear control water drainage mechanism (2) and a hydraulic water drainage mechanism (3) controlled by a micro-immersible pump (31). The linear control water drainage mechanism (2) comprises a piston (21) with the piston (21) being partitioned into an upper and lower chamber by a central partition plate (211); the upper chamber is a piston control chamber for controlling the resetting of the piston (21), and the linear control water drainage mechanism (2) controls the upward action of the piston (21); and the lower chamber is a water drainage fluid chamber (24) for creating water pressure on the piston. More than one through hole (2111) is provided in the central partition plate (211) to communicate with the upper and lower chambers partitioned by the central partition plate (211), and the sum total of the size of the cross-sectional area of all the through holes (2111) in the central partition plate (211) is no greater than 15 square millimetres. The improved dual control mode-type deodorising and water drainage valve has a simple structure and can remove toilet odors and peculiar smells.
