Vacuum cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners require simultaneous two-handed operation for dust cup installation/removal, leading to secondary contamination due to dust falling from the filter.
Innovation Solution
A vacuum cleaning device with an unlocking mechanism that allows the dust cup and filter to be locked or unlocked, enabling automatic disengagement from the vacuum channel to an easy-to-take state, preventing secondary pollution and simplifying single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust cup is removed from the body of the horizontal-type vacuum cleaner, then the dust cup can be taken out for cleaning, but dust and the like on the filter easily fall off and cause secondary contamination
Solution Approach 1:
The patent combines the filter and dust cup into a single integrated assembly that is removed together as one unit. The filter is positioned inside the dust cup and both components are locked and unlocked simultaneously through the same locking mechanism, preventing dust from falling off during removal operations.
Solution Approach 2:
The locking mechanism is designed to automatically lock the filter and dust cup together before removal occurs. This preliminary locking action ensures that the filter remains securely in place within the dust cup throughout the removal process, preventing dust from falling off beforehand.
2Reliability
If simultaneous two-handed operation is required for dust cup installation or removal, then the locking mechanism can secure the dust cup, but it is difficult for a user to operate
Solution Approach 1:
The locking mechanism is designed to automatically lock and unlock the dust cup without requiring manual intervention for each action. The user simply needs to press the release button, and the mechanism automatically coordinates the unlocking of both the dust cup and filter together, making the operation simple and intuitive.
Solution Approach 2:
The patent combines the locking actions for the dust cup and filter into a single integrated mechanism. One release button controls both unlocking actions simultaneously, eliminating the need for separate two-handed operations and simplifying the user interface.
3Ease of operation
If the dust cup and filter are removed separately, then the dust cup can be taken out, but the filter remains in the body causing potential dust fallout
Solution Approach 1:
The patent merges the filter and dust cup into a single removable assembly. The filter is positioned inside the dust cup and both components share the same locking mechanism, ensuring they are removed together as one unit rather than separately, preventing dust fallout from the filter.

AI summary
The invention relates to a vacuum cleaning device, including a body (1), a dust cup (2), and an unlocking mechanism (3) for unlocking and locking the dust cup (2). The body (1) is provided with a vacuum cleaning channel, a filter (4) is provided in the dust cup (2), the unlocking mechanism (3) is configured to have a locking state and an unlocking state, and when the unlocking mechanism (3) is in the locking state, the dust cup (2) and the body (1) are locked together in a sealing manner, and the vacuum cleaning channel is in communication with the filter (4) and the dust cup (2) such that the filter (4) and the dust cup (2) are in a working state; and when the unlocking mechanism (3) is in the unlocking state, the dust cup (2) and the filter (4) are automatically disengaged from the vacuum cleaning channel to an easy-to-take state.
