Vacuum Station Lever Locking for Dust Bag Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaner stations face issues with damage from scattered dust and dust leakage due to improper dust bag placement and full dust bag unlocking, leading to unintentional holder unlocking and dust leakage.
Innovation Solution
A station design with a dockable dust canister, a housing for a dust bag, a cover that opens and closes, and a lever system that ensures the dust bag is securely mounted and prevents unintentional unlocking, using support members and a torsion spring for stability and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holder is made easily detachable for dust bag replacement, then the ease of operation is improved, but the reliability of preventing unintentional unlocking deteriorates
Solution Approach 1:
The holder employs a dynamic locking mechanism with a movable locking bar that can transition between locked and unlocked states. The locking bar is biased by a spring to engage with the locking protrusion, but can be disengaged by applying force in a specific direction, allowing easy dust bag replacement while maintaining secure locking during normal operation.
Solution Approach 2:
The locking mechanism uses an intermediary locking bar that mediates between the holder body and the dust bag. This locking bar with its protrusion and groove interface provides a reliable mechanical connection that prevents unintentional unlocking while allowing controlled detachment when needed.
2Ease of operation
If the cover is made easily openable for dust bag access, then the ease of operation is improved, but the protection from scattered dust deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically closing the cover when the holder is properly installed with a dust bag. The cover closing mechanism is triggered in advance by the holder installation, ensuring the housing is sealed before dust collection begins, thus preventing dust scattering while maintaining easy access when needed.
Solution Approach 2:
The cover mechanism incorporates feedback from the holder installation state. When the holder is properly installed, it triggers the cover to close automatically. This feedback mechanism ensures the housing remains sealed during operation to prevent dust scattering, while allowing easy opening when the holder needs to be accessed.
3Device complexity
If the station uses a simple holder structure, then the device complexity is reduced, but the reliability of dust bag retention deteriorates
Solution Approach 1:
The holder uses an intermediary locking bar as a mediating component between the simple holder body and the dust bag. This locking bar provides the necessary reliability for dust bag retention through its engagement mechanism with the locking protrusion, while the overall holder structure remains relatively simple and easy to manufacture.
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
Prevents damage from scattered dust, ensures secure dust bag mounting, and reduces dust leakage by maintaining the holder's locked position even when the dust bag is full, enhancing the station's durability and reducing manufacturing costs.
Implementation Method 1
The lever is rotatably coupled in the housing and includes a torsion spring that provides an elastic force in the first direction.

AI summary
A station for a cleaning device is provided. The station includes an accommodation chamber configured to be docked with the dust canister, a housing configured to have a dust bag disposed therein, a cover configured to open and close one region of the housing, a holder configured to be detachable to the dust bag and selectively communicate the dust bag with the accommodation chamber, and a lever configured to have one end disposed in one region of the housing and rotate in a first direction to selectively interfere with the cover. The lever rotates in a second direction opposite to the first direction to close the cover based on the dust bag being mounted on the holder and in communication with the accommodation chamber.
