Dust Collector Barrel Lid Linkage for Fast Airtight Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting devices face difficulties in quickly and conveniently loading and unloading the dust collecting barrel due to the time-consuming detachment and installation of fastening members, especially when the device is positioned against a wall or in a corner.
Innovation Solution
A dust collector design featuring a telescopic tube, pivot ears, and linking members connected to an operation unit that allows the dust collecting barrel lid to be easily lifted or swung for detachment and reattachment, facilitated by gravity and spring force for airtight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastening members are disposed on the periphery of the dust collecting barrel lid to ensure airtight fastening, then the sealing reliability is improved, but the time required for detachment and installation increases significantly
Solution Approach 1:
The fastening mechanism is segmented into multiple independent fastening members distributed around the periphery of the dust collecting barrel lid. Each fastening member can be operated independently, allowing the system to maintain airtight sealing through multiple points while enabling quick detachment by simply lifting the operation unit, which simultaneously releases all fastening members without requiring sequential manual operation.
Solution Approach 2:
The fastening members are designed to automatically engage and disengage through the operation unit's movement. When the operation unit is lifted, the fastening members automatically detach from their corresponding positions on the dust collecting barrel, and when lowered, they automatically re-engage. This self-service mechanism eliminates the need for manual fastening or unfastening operations, significantly reducing loading and unloading time while maintaining reliable airtight sealing.
2Area of stationary object
If the dust collecting device is positioned against a wall or in a corner to save space, then the space utilization is improved, but the accessibility for operating fastening members deteriorates
Solution Approach 1:
The operation unit serves as an intermediary mechanism that translates a single user action (lifting or lowering) into the coordinated movement of multiple fastening members. By positioning the operation unit at a conveniently accessible location on the dust collecting barrel lid, users can operate the fastening members from a distance, eliminating the need to physically reach around corners or behind walls. This intermediary mechanism maintains ease of operation even when the device is positioned in space-constrained locations.
Solution Approach 2:
The fastening mechanism is designed to operate primarily in the vertical dimension through the operation unit's up-and-down movement, rather than requiring horizontal or lateral access to multiple fastening points. This dimensional change allows users to access and operate the mechanism from the front or top of the device, making it accessible even when the dust collector is positioned against a wall or in a corner, thereby maintaining ease of operation in space-constrained environments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and convenient loading and unloading of the dust collecting barrel, significantly increasing working efficiency by simplifying the detachment and attachment process.
Implementation Method 1
One end of each linking member is pivotally connected to the operation unit, and the other end of each linking member is pivotally connected to the dust collecting barrel lid. The linking members are driven by the operation unit to move the dust collecting barrel lid upwards and downwards.
Implementation Method 2
the dust collecting barrel lid can be forcedly attached to the dust collecting barrel by the gravity of the operation unit

AI summary
A dust collector with convenient loading and unloading dust collecting barrel includes a base plate fixed on an outer periphery of a bottom of an air guide cylinder, an operation unit whose end is pivotally arranged on the base plate, linking members disposed on said operation unit and connected to a dust collecting barrel lid located under the air guide tube. Accordingly, when a user lifts up the operation unit, the linking members move the dust collecting barrel lid upwards. The upward movement separates the dust collecting barrel lid from the dust collecting barrel, so the dust collecting barrel is easily detached. The action of swinging the operation unit swings down allows the linking members to move the dust collecting barrel lid downwards, so the dust collecting barrel lid closes the dust collecting barrel. Therefore, the user loads and unloads the dust collecting barrel quickly and conveniently.
