Linkage limiting assembly applied in vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vacuum cleaners require complex manual operations to open and empty the dust barrel, particularly the front flip type, which is inconvenient for users.
Innovation Solution
A linkage limiting assembly within the vacuum cleaner frame, comprising a triggering button, a pushing member, a limiting member, and a linking member, allows users to release the dust barrel or electric fan assembly instantly by pressing the button, enabling easy upward movement and automatic dust cover opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a front flip type dust barrel is used, then the dust barrel can be opened by flipping, but the operation becomes complex requiring manual opening of buckling portions
Solution Approach 1:
The dust barrel is designed to automatically open the dust cover and separate from the main body through its own weight and the linkage mechanism, without requiring manual operation of buckling portions. The self-weight of the dust barrel drives the automatic opening process when the limiting member is released.
Solution Approach 2:
A linkage mechanism consisting of a pushing member, linking member, and limiting member is introduced as an intermediary between the user's simple button press and the complex dust barrel opening action. This linkage mechanism translates the simple triggering button press into coordinated movement of multiple components including the dust cover opening and dust barrel separation.
2Productivity
If manual opening of buckling portions is required, then the structure can be simple, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The dust cover is pre-positioned on the dust barrel with a buckling structure that is ready to engage and disengage. The limiting member is pre-configured to control the opening sequence, so that when triggered, the dust cover automatically opens and the dust barrel separates without requiring sequential manual operations.
Solution Approach 2:
The system transitions from a static locked state to a dynamic opening process when the triggering button is pressed. The limiting member rotates from a locked position to an unlocked position, enabling the dust barrel to move dynamically from a closed state to an open state through controlled motion of the linkage mechanism.
3Ease of operation
If a linkage mechanism is added to enable automatic opening, then operation becomes convenient, but the device structure becomes more complex
Solution Approach 1:
The linkage mechanism is designed so that a single triggering button press simultaneously activates multiple functions: releasing the limiting member, pushing the dust cover open, and enabling dust barrel separation. This multi-functionality reduces the need for separate control mechanisms for each action.
Solution Approach 2:
The linkage mechanism components are nested within the existing dust barrel structure. The pushing member is embedded in the dust barrel, the linking member connects existing components, and the limiting member is integrated into the frame, minimizing additional space requirements and structural disruption.

AI summary
Disclosed is a linkage limiting assembly applied in a vacuum cleaner, which is mounted within a frame (7) of the vacuum cleaner. The linkage limiting assembly includes a triggering button (1) arranged at the rear end of the frame (7), a pushing member (4) configured to push an electric fan assembly (9) or a dust barrel (8) of the vacuum cleaner upwards, a limiting member (3) configured to limit the maximum stroke of the electric fan assembly (9) or the dust barrel (8), and a linking member (2) connecting the triggering button (1) with the limiting member (3) in a force transmission manner.
