Air Purifier Filter Frame Layout for Wall-Facing Booster Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers require users to change filters by altering the overall layout, making it inconvenient, and have electrical wires exposed in inconvenient directions, complicating maintenance.
Innovation Solution
An air purifier design with a booster that allows filter replacement in the direction faced by the booster outlet, separate inlet covers for easy access, and electrical wires positioned opposite the booster outlet for convenient placement near the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the booster is disposed to face a wall surface or corner, then the air purifier can be installed in compact spaces, but the filter replacement becomes inconvenient requiring layout changes
Solution Approach 1:
The inlet cover is divided into a first inlet cover and a second inlet cover that can be separately removed. The first inlet cover is disposed at the front side of the filter and can be individually removed to provide access to the filter, while the second inlet cover remains attached. This segmentation allows filter replacement without requiring removal of the entire inlet cover assembly, thus maintaining installation flexibility while improving maintenance convenience.
2Adaptability or versatility
If the electrical wire area is disposed away from the wall, then the air purifier has more design freedom, but the wire management becomes complicated and inconvenient
Solution Approach 1:
Instead of disposing the electrical wire area in a conventional location, the patent positions the electrical wire area at the rear side of the air purifier body, opposite to the booster outlet direction. This inverted positioning allows the electrical wire to be conveniently connected to wall outlets when the purifier is placed against a wall, simplifying wire management while maintaining design freedom for the main body configuration.
3Device complexity
If the inlet cover is made as a single integrated piece, then the structure is simpler, but the filter access requires complete disassembly
Solution Approach 1:
The inlet cover is segmented into a first inlet cover and a second inlet cover. The first inlet cover is disposed at the front side of the filter and can be individually removed to provide direct access to the filter for replacement or cleaning. The second inlet cover remains attached to the body. This segmentation balances structural simplicity with ease of filter access, as the division is straightforward and the separate removal of the first inlet cover enables maintenance without complete disassembly.

AI summary
The air purifier of the present disclosure includes: a body having an inlet formed on an circumference surface thereof and an outlet formed on an upper surface thereof; and a booster disposed at an upper side of the body, and discharging air in one direction on the circumference surface through a booster outlet. The body includes a fan disposed inside the body and making air flow from the inlet to the outlet, a fan housing having a space in which the fan is disposed, a filter disposed at a lower side of the fan housing, and filtering air introduced through the inlet, and a filter frame extended to a lower side from the fan housing, and supporting a space in which the filter is disposed. The filter frame is disposed to withdraw the filter in a direction faced by the booster outlet.
