Vacuum Cleaner Linkage Release Assembly for Easy Dust Barrel Opening
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 easily release the dust barrel or electric fan assembly by pressing the button, enabling 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 manual operation becomes complex and inconvenient
Solution Approach 1:
The dust barrel is designed to automatically flip open when the vacuum cleaner body is tilted forward. The gravity-based self-service mechanism eliminates the need for manual buckling operations, allowing users to simply tilt the device to access the dust barrel for emptying
Solution Approach 2:
The dust barrel assembly is segmented into a dust barrel body and a separate dust cover that can move independently. This segmentation allows the dust cover to flip open automatically while the dust barrel remains attached to the vacuum cleaner body, enabling easy access without complete disassembly
2Stability of the object's composition
If the dust barrel is firmly limited to prevent accidental opening, then structural stability is improved, but ease of operation deteriorates
Solution Approach 1:
The limiting mechanism transitions from a static locked state to a dynamic release state when the vacuum cleaner body is tilted forward. The limiting member rotates about its axis under the combined action of spring force and gravity, dynamically switching between constraining and releasing the dust barrel based on the device's orientation
Solution Approach 2:
The spring is pre-compressed to store elastic potential energy that automatically acts on the limiting member when the vacuum cleaner is tilted. This preliminary action ensures that the dust barrel is ready to flip open immediately when the tilting condition is met, without requiring additional user effort

Function Achieved in This Case
Facilitates convenient operation by allowing users to instantly release and move the dust barrel or electric fan assembly upwards with thumb pressure, enhancing usability and efficiency in dust removal.
Implementation Method 1
a first spring is embedded within the frame, and two ends of the first spring respectively abut against the inner wall of the frame and one side of the limiting member away from the buckling structure
Implementation Method 2
the pushing sleeve has an opening at a lower end thereof and a second spring is embedded within the opening
Implementation Method 3
a third spring abuts against the inner side of the linking member, and the other end of the third spring abuts against a bracket structure within the frame

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