Air Purifier Housing Locking Structure for Easy Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifier housings have complex and inconvenient filter element replacement processes, making it difficult for users to efficiently swap out filter elements.
Innovation Solution
The air purifier housing features a limiting structure with a rotary convex platform, insertion grooves, and inner container protrusions that allow for easy assembly and disassembly, enabling the filter element to be replaced by rotating the convex platform to disengage the protrusions from the grooves, allowing the outer cover to be detached with minimal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional fixed housing structure is used, then the structural stability is improved, but the filter element replacement becomes difficult and complex
Solution Approach 1:
The housing transitions from a static fixed structure to a dynamic structure with movable components. The outer cover can be moved between locked and unlocked positions, allowing the filter element to be easily accessed and replaced while maintaining structural stability during normal operation.
Solution Approach 2:
The housing is divided into separate segments including the outer cover, bottom bracket, and filter element. This segmentation allows the outer cover to be independently moved to access the filter element, simplifying replacement while maintaining overall structural integrity.
2Ease of manufacture
If a simple insertion structure is used, then the assembly ease is improved, but the locking reliability becomes insufficient
Solution Approach 1:
Multiple locking functions are merged into a single integrated limiting structure that includes the driving part, inner container protrusions, and engagement features. This structure simultaneously provides insertion guidance, locking, and positioning functions, achieving both ease of assembly and reliable locking.
Solution Approach 2:
The limiting structure acts as an intermediary mechanism between the outer cover and bottom bracket. It mediates the connection by providing controlled movement and secure engagement, ensuring both easy assembly and reliable locking without requiring complex separate mechanisms.

AI summary
An air purifier housing comprises an outer cover and a bottom bracket with a center cavity which is open downwards and insertion grooves, recessing openings stretching into the center cavity are formed in side walls of the insertion grooves, insertion rods are fixed on the outer cover, which is inserted into the insertion grooves through the insertion rods; installation grooves corresponding to the recessing openings are in the insertion rods; and a limiting structure is in the center cavity and comprises a driving part and inner container protrusions which correspond to the recessing openings, and the driving part connects with the inner container protrusions and drives them to reach a first position where the inner container protrusions stretch out of the insertion grooves to be inserted into the installation grooves of the insertion rods or to reach a second position where the inner container protrusions retreat into the center cavity.
