Floor Sweeper Inlet Sealing Plate for Garbage Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor sweepers face issues with garbage leakage from the garbage collection cavity due to unsealed inlets during bumps when transitioning between cleaning regions, leading to user inconvenience.
Innovation Solution
A floor sweeper design featuring a sealing plate controlled by an ejector rod, which opens the inlet during cleaning and seals it when lifted, utilizing a connecting-rod structure and elastic piece to ensure reliable sealing, along with a detachable sweeping roller for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inlet of the garbage cavity is kept open for easy garbage entry during cleaning, then the ease of operation is improved, but garbage leakage occurs during bumps in non-working state
Solution Approach 1:
The sealing plate is designed to dynamically switch between open and closed states based on the working condition. During cleaning operation, the ejector rod pushes the sealing plate open to allow garbage entry. During transport or idle state, the spring returns the sealing plate to closed position to prevent leakage. This dynamic state change resolves the contradiction between ease of garbage entry and sealing reliability.
Solution Approach 2:
The spring is pre-loaded to maintain the sealing plate in the closed position before cleaning operation begins. This preliminary action ensures that the sealing plate is ready to seal immediately when the ejector rod retracts, preventing any potential leakage during transitions between working and non-working states.
2Stability of the object's composition
If the sweeping roller is made fixed for structural stability, then the stability of the object's composition is improved, but maintenance and replacement become difficult
Solution Approach 1:
The sweeping roller is designed as a separate, detachable component from the housing. It can be easily removed and replaced by detaching it from the mounting groove, while the housing and other components remain stable. This segmentation allows the sweeping roller to be maintained or replaced independently without affecting the overall structural stability of the floor sweeper.
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 garbage leakage by maintaining a sealed inlet during non-working states and allows for rapid assembly and maintenance of the sweeping roller, enhancing operational stability and convenience.
Implementation Method 1
the floor sweeper further comprises an elastic piece connected to the link shaft or the sealing plate, and the elastic piece applies a force to the link shaft or the sealing plate to enable the sealing plate to seal the inlet

AI summary
A floor sweeper includes a housing which has a garbage cavity for containing garbage. The garbage cavity has an inlet allowing the garbage to enter the garbage cavity. A sweeping roller is disposed at the inlet of the garbage cavity, is rotatably connected to the housing and is able to sweep outside garbage into the garbage cavity. A sealing plate for opening/closing the inlet is disposed at the inlet of the garbage cavity. An ejector rod is vertically and movably connected to the housing, has an upper end connected to the sealing plate and is able to move vertically to drive the sealing plate to move. When floor sweeper cleans a floor, the ejector rod abuts against the floor and moves upwards to drive the sealing plate to move to open the inlet of the garbage cavity.
