Negative Ion Generator Positioning in Air Purifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stability of negative ion generators at the air outlet of air cleaners is poor, leading to reduced air purification efficiency due to neutralization of negative ions before they can be released.
Innovation Solution
A purifying device with an air guiding part, a negative ion generator, and an air guiding cover, where the negative ion generator includes an emitting head that is positioned and secured using a first position limiting structure and an air guiding cover, allowing for stable installation and increased migration distance of negative ions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the negative ion generator is installed near the air outlet, then the migration distance of negative ions is increased, but the stability of the negative ion generator deteriorates
Solution Approach 1:
The negative ion generator is divided into a fixed portion (mounted on the air outlet) and a detachable emitting head portion. The emitting head can be replaced or adjusted independently, allowing the generator to maintain stable installation while enabling easy maintenance and optimization of ion emission performance.
Solution Approach 2:
The negative ion generator incorporates an adjustable emitting head that can be positioned at different distances from the air outlet. This dynamic adjustment capability allows optimization of the migration distance for different operating conditions while maintaining stable installation through the fixed mounting structure.
2Productivity
If the negative ion generator is installed at the air outlet, then the air purification efficiency is improved, but the generator loosens and falls affecting stability
Solution Approach 1:
The generator is segmented into a fixed mounting base and a removable emitting head. The mounting base remains securely fixed to the air outlet, providing stable installation, while the emitting head can be independently replaced or adjusted to maintain optimal purification performance without compromising stability.
Solution Approach 2:
The emitting head is pre-configured with positioning features that ensure proper alignment and secure attachment to the mounting base. This preliminary design of the connection mechanism prevents loosening and falling during operation, ensuring both high purification efficiency and reliable stability.
