Filter Element Mounting Structure With Automatic Ejecting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing filter element mounting process is cumbersome and difficult for non-professionals due to interference fits requiring manual force and laborious disassembly, especially with the slide stopping portion's structural characteristics.
Innovation Solution
A filter element mounting structure with a driving mechanism, limiting member, and intelligent control detection unit that allows for automatic assembly and disassembly by moving the limiting member through multiple locking positions, providing locking and ejecting forces, and using a switch member for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interference fit between sealing ring and base interface is used for mounting, then sealing effect is improved, but mounting operation becomes difficult requiring excessive manual force
Solution Approach 1:
A guide rod is introduced as an intermediary component between the filter element and the base. The guide rod includes a guiding portion that guides the sealing ring during mounting, allowing the sealing ring to be elastically deformed and fitted onto the base interface without requiring excessive manual force, while still achieving reliable sealing
2Reliability
If slide stopping portion structure is used for locking, then locking reliability is improved, but disassembly operation becomes particularly laborious
Solution Approach 1:
The limiting member is designed to be movable along the guide rod, transitioning between different positions (first position for guiding, second position for locking). This dynamic design allows the limiting member to automatically move to the locking position during mounting, providing reliable locking without requiring laborious manual operation for disassembly
3Reliability
If manual screwing force and inserting force are required for mounting, then secure locking is achieved, but operation complexity increases requiring two hands and host machine stabilization
Solution Approach 1:
The filter element structure is designed to be self-guiding during mounting. The guide rod automatically guides the sealing ring and limiting member into their correct positions, and the limiting member automatically moves to the locking position. This self-service mechanism eliminates the need for complex two-handed operations and host machine stabilization, reducing operation complexity while maintaining secure locking

AI summary
A filter element mounting structure comprises a switch member arranged on a shell, a limiting member and a driving mechanism; the driving mechanism is arranged on the shell, the limiting member is connected with the driving mechanism, a locking groove is formed on a filter element, the limiting member comprises a plurality of locking positions comprising a first locking position, a second locking position and a third locking position; when the limiting member is in the first locking position, the filter element is mounted in the shell, when the filter element is mounted in the shell, the switch member is touched, and the driving mechanism controls the limiting member to move to the second locking position and lock the filter element; and when the driving mechanism drives the limiting member to move to the third locking position, the limiting member provides an ejecting force to eject the filter element.
