Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid atomization devices are prone to clogging due to the small size of the water stop mechanism in the drain pipe, which allows foreign matter to accumulate, leading to operational issues.
Innovation Solution
The device incorporates a pumping pipe that generates a whirlpool in the reservoir, creating a void between the pumping and drain ports, preventing water drainage during operation and allowing for efficient drainage after operation stops, eliminating the need for a drain valve and reducing clogging risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drain valve is used in the drain pipe to control water drainage, then water can be stopped during operation, but the small size of the water stop mechanism causes the drain mechanism to be easily clogged with foreign matter
Solution Approach 1:
The invention extracts the drain valve mechanism from the drain pipe system and replaces it with a valveless design. The pumping pipe's rotation creates a whirlpool that naturally controls water flow, eliminating the small drain valve that was prone to clogging while maintaining the ability to stop water drainage during operation.
Solution Approach 2:
The invention uses hydraulic principles by utilizing the whirlpool effect created by the rotating pumping pipe to control water flow. The centrifugal force and pressure differential generated by the whirlpool naturally prevent water from entering the drain pipe during operation, replacing the mechanical drain valve with a fluid dynamics-based control mechanism.
2Reliability
If a drain valve is installed to prevent water drainage during operation, then water control is achieved, but the complex mechanism increases device complexity and maintenance requirements
Solution Approach 1:
The invention removes the drain valve component entirely from the system. Instead of having a separate water control mechanism, the pumping pipe's rotation itself controls water flow through the whirlpool effect, simplifying the overall device structure and reducing maintenance requirements.
Solution Approach 2:
The pumping pipe serves multiple functions: it pumps water upward for atomization and simultaneously controls water drainage through the whirlpool effect created during rotation. This multi-functionality eliminates the need for a separate drain valve mechanism, reducing device complexity.
3Object-affected harmful factors
If the drain port is made larger to prevent clogging, then foreign matter can pass through more easily, but water cannot be effectively stopped during operation
Solution Approach 1:
The invention uses hydraulic control through the whirlpool effect to stop water drainage. The centrifugal force and pressure differential generated by the rotating pumping pipe prevent water from entering the drain port, allowing the drain port to be larger without compromising water stop capability.
Solution Approach 2:
The invention implements dynamic water control through the rotation of the pumping pipe. The whirlpool effect is created only during rotation, allowing the system to dynamically stop water drainage during operation while maintaining an open drain port that resists clogging.

Implementation Method 1
The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation of the pumping pipe
Implementation Method 2

AI summary
A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.
