Vacuum Dust Barrel Front Cover with Automatic Opening Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vacuum cleaners require complex and inconvenient processes to open and empty the dust barrel, particularly the front flip type, which necessitates manual operation of a buckling portion for rotation and opening.
Innovation Solution
A handheld vacuum cleaner design featuring a dust barrel with a rotatable front cover and a locking portion that moves relative to the frame, utilizing a torsional spring mechanism for automatic opening and closing, and an electric fan assembly connected to the frame for easy operation, along with a linkage limiting assembly for controlled dust removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a front flip type dust barrel with manual buckling portion is used, then the dust barrel can be opened, but the operation becomes complicated and inconvenient
Solution Approach 1:
The dust barrel automatically opens itself when the lifting member raises it, without requiring manual operation of a buckling portion. The front cover is equipped with an automatic opening mechanism that detects the lifting action and autonomously executes the opening sequence, making the system serve itself rather than requiring user intervention for complex operations.
Solution Approach 2:
The lifting member is configured to raise the dust barrel before the opening operation is needed. By performing the lifting action in advance, the system triggers the automatic opening mechanism to prepare the dust barrel for emptying, so that when the user needs to empty it, the opening process has already been initiated or is ready to execute automatically.
2Productivity
If overall disassembly type or front flip type dust barrel is used, then dust can be removed, but the process becomes complicated requiring manual buckling operation
Solution Approach 1:
The dust barrel system performs self-opening through the automatic opening mechanism activated by the lifting member, eliminating the time-consuming manual buckling operation. The entire opening sequence executes automatically once the lifting action is initiated, significantly reducing the time required to prepare the dust barrel for emptying and improving overall productivity.
Solution Approach 2:
The lifting member raises the dust barrel in advance to trigger the automatic opening mechanism, so that the opening process begins before the user actually needs to empty the dust. This preliminary action reduces the waiting time and accelerates the overall dust removal process by pre-initiating the opening sequence.
3Ease of operation
If manual buckling portion operation is required, then the front cover can be opened, but the operation becomes inconvenient
Solution Approach 1:
The front cover opening mechanism serves itself by automatically detecting the lifting action of the dust barrel and executing the opening sequence without human intervention. The mechanism includes sensors or mechanical linkages that respond to the lifting motion and autonomously control the buckling portion and front cover, achieving high automation while maintaining ease of operation.
Solution Approach 2:
The lifting member performs the preliminary action of raising the dust barrel, which automatically triggers the front cover opening mechanism. This preliminary lifting action initiates the automated sequence that prepares the front cover for opening, eliminating the need for users to manually operate the buckling portion and improving both automation and convenience.
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
Facilitates convenient and reliable automatic opening of the dust barrel for dust removal without manual disassembly, enhancing operational ease and efficiency.
Implementation Method 1
a torsional spring embedded within the fixed sleeve and mounted around the connecting shaft; one end of the torsional spring abuts against an outer edge of the front cover and provides the front cover with a rotating force relative to the dust barrel
Implementation Method 2
a rear end of the dust barrel is connected with an electric fan assembly

AI summary
Disclosed are a handheld vacuum cleaner and a handheld and upright integrated vacuum cleaner. The handheld vacuum cleaner includes a frame (1), and a dust barrel (2) and a locking portion (3) which are mounted on the frame (1). A front end of the dust barrel (2) and the locking portion (3) are capable of moving with respect to each other and are opposite in position. Moreover, the dust barrel (2) has a rotatable front cover (5) at a front side thereof. When the locking portion (3) and the dust barrel (2) move with respect to each other, the front cover (5) may be automatically rotated and opened or limited by the locking portion (3) to be covered on the front side of the dust barrel (2). The dust barrel (2) and the locking portion (3) are capable of moving with respect to each other, and during the movement, the front cover (5) is automatically opened or limited by the locking portion (3) to be covered on the dust barrel (2), such that the front cover (5) may be conveniently unlocked by means of the movement of the dust barrel (2) and/or the locking portion (3), and further the dust barrel (2) may be automatically opened for removing dust, without specially disassembling the dust barrel (2) and manually opening the front cover (5) for removing dust. Accordingly, the operation of removing dust is greatly facilitated and the convenience and reliability are brought for the operation.
