Air Purifier Coupling Mechanism for Easy Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifier devices face difficulties in filter replacement, making the process cumbersome and risking improper filter positioning, which can impair the device's function.
Innovation Solution
The air purifier device is structurally divided into a fan unit and a filter unit, with a coupling mechanism featuring release means on opposite outer sides of the fan unit, allowing for easy removal and replacement of the filter unit by lifting the fan unit off, facilitating correct positioning and reducing the risk of impaired function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is secured to the housing with a grille that needs to be tilted and lifted out, then the filter is securely held in place, but the filter replacement becomes cumbersome and difficult for the user
Solution Approach 1:
The device is divided into two separable units: a filter unit and a fan unit. The coupling mechanism includes release means on opposite outer sides of the fan unit that, when actuated, allow the fan unit to be lifted off the filter unit. This segmentation enables easy filter replacement while maintaining secure operation during use.
2Reliability
If the filter replacement process is complex requiring tilting and lifting, then the filter is securely attached, but the risk of incorrect positioning increases impairing device function
Solution Approach 1:
By separating the device into filter unit and fan unit with a simple coupling mechanism, the invention reduces replacement complexity to a single lifting action while maintaining secure attachment during operation, thereby reducing the risk of incorrect positioning.
Solution Approach 2:
The coupling mechanism is designed to be self-aligning and self-securing. When the fan unit is placed on the filter unit, the coupling mechanism automatically engages without requiring precise manual positioning, reducing the risk of incorrect installation.

AI summary
An air purifier device is provided including a fan unit including a fan arranged to produce an air flow through the air purifier device, and a filter unit including a filter arranged to filter the air flow produced by the fan. The filter unit is adapted to stand on a support surface when the air purifier device is positioned for use. The air purifier device further includes a coupling mechanism arranged to secure the fan unit on top of the filter unit. The coupling mechanism includes two release means arranged on opposite outer sides of the fan unit, and the fan unit is releasable from the filter unit by actuating the two release means. The filter unit may be removed from the fan unit by a single action (or movement) by the user, whereby filter replacement of the air purifier device is facilitated.
