Vacuum Cleaner Dust Bag Removal Using Rotating Bracket Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors require users to directly contact the dust collecting bag to remove it, leading to dust adherence and complications with buckle structures, making the process inefficient and user-unfriendly.
Innovation Solution
A dust collector design featuring a rotating bracket and supporting plate system that allows the dust collecting bag to be separated without direct contact, utilizing a rotating member and elastic members to facilitate easy removal by changing the operating member's state, enabling the supporting plate to separate from the connecting member due to gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly contacts the dust collecting bag with hands to take it down, then the operation is simple, but dust will adhere to the user's body, influencing user experience
Solution Approach 1:
The patent introduces an intermediary mechanism (the bracket with rotating member and operating member) that mediates between the user and the dust collecting bag. The user operates the button without directly touching the bag, and the intermediary mechanism transfers this operation to achieve bag removal, thus preventing dust contact while maintaining operational simplicity
Solution Approach 2:
The dust collecting bag system is designed to be self-servicing through the automatic release mechanism. When the operating member is actuated, the bracket automatically rotates and releases the bag without requiring the user to manually grasp or manipulate the bag itself, allowing the system to perform the removal service autonomously
2Reliability
If at least two buckle structures are equipped to achieve stable mounting, then the dust collecting bag is prevented from accidentally falling off, but the overall structure becomes more complicated and the dust collecting bag can't be separated after full of dust
Solution Approach 1:
The patent transforms the static buckle structure into a dynamic system with a rotating bracket. The bracket can rotate between a first position (secured state) and a second position (released state), allowing the same single buckle structure to provide both stable mounting and easy release functionality based on its rotational position
Solution Approach 2:
The single buckle structure is designed to perform multiple functions: it provides secure mounting when the bracket is in the first position, and enables easy release when the bracket rotates to the second position. This multi-functional design eliminates the need for separate buckle structures while maintaining both stability and operability
3Reliability
If at least two buckle structures are equipped to achieve stable mounting, then the dust collecting bag is prevented from accidentally falling off, but the dust collecting bag can't be separated from the buckle structure after full of dust by pressing the button
Solution Approach 1:
The rotating bracket provides a dynamic release mechanism that works regardless of the bag's fill status. The rotation from first to second position mechanically disengages the buckle structure, providing a reliable release path that is not blocked by dust accumulation in the bag
Solution Approach 2:
The mounting system is segmented into independent functional components: the buckle structure provides secure attachment, while the rotating bracket provides release capability. This segmentation allows the release function to operate independently of the bag's content status, ensuring operability even when the bag is full

Function Achieved in This Case
Enables quick and efficient removal of the dust collecting bag without dust adhering to the user, simplifying the process and improving user experience by reducing structural complexity and preventing accidental detachment issues.
Implementation Method 1
the bracket is pushed to move to a first position, and at this moment, the operating member is in a first state, the operating member is connected with the bracket, and the supporting plate is connected with the connecting portion in the housing; the bracket can rotate between the first position and the second position around the rotating member provided in the housing

AI summary
A dust collector with a dust collecting bag includes a housing defining a dust collecting chamber; a bracket in the dust collecting chamber; an operating member connectable with the bracket; the dust collecting bag being mounted to a supporting plate; and the bracket being rotatable around a rotating member from a first position to a second position. The housing further includes a connecting member, and the operating member includes a first state and a second state. When the operating member is in the first state, the bracket is located at the first position, and the supporting plate mounted on the bracket is connected with the connecting member. When the operating member is in the second state, the bracket drives the supporting plate to move towards the second position so that the supporting plate is separated from the connecting member, and the supporting plate is separated from the bracket.
