Roller brush assembly and cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face inefficiencies in continuously removing garbage that is not initially sucked into the suction port, leading to reduced cleaning effectiveness and potential ground pollution.
Innovation Solution
A roller brush assembly comprising a main roller brush driven by an electric motor and an auxiliary roller brush, arranged to rotate in a direction opposite to the main brush, ensures that garbage not initially sucked is swept back into the suction area for re-collection, enhancing cleaning quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single main roller brush is used for sweeping, then the structure is simple, but garbage that is not initially sucked remains on the ground affecting cleaning effectiveness
Solution Approach 1:
The roller brush assembly is segmented into a main roller brush and an auxiliary roller brush, each performing distinct functions. The main roller brush handles primary sweeping while the auxiliary roller brush handles re-sweeping of missed garbage, thereby improving cleaning efficiency without requiring a completely new system
Solution Approach 2:
The auxiliary roller brush serves multiple purposes: it sweeps garbage that was missed by the main roller brush, pushes garbage toward the suction port, and can adapt to different cleaning scenarios. This multi-functionality improves productivity while keeping the overall device complexity manageable
2Reliability
If the sealing member pushes garbage along the ground, then the sealing member maintains contact with the ground, but garbage accumulates in front of the sealing member and is not continuously removed
Solution Approach 1:
The auxiliary roller brush is positioned at the rear of the main roller brush to perform preliminary action on garbage that escapes the main brush. It sweeps and pushes this garbage forward before the main roller brush reaches it, ensuring continuous garbage removal and preventing accumulation in front of the sealing member
Solution Approach 2:
The auxiliary roller brush operates continuously alongside the main roller brush, creating an overlapping cleaning zone. This continuous action ensures that garbage is constantly swept toward the suction port without interruption, maintaining both sealing effectiveness and continuous removal capability
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
The auxiliary roller brush effectively re-sweeps and re-sucks garbage that was initially missed, improving the overall cleaning quality and efficiency by ensuring continuous removal and minimizing ground pollution.
Implementation Method 1
an electric motor configured to drive the main roller brush to rotate to sweep a surface to be cleaned
Implementation Method 2
the sweeping member contacts and pushes the protrusion to drive the auxiliary roller brush body to rotate in a direction opposite to rotation of the main roller brush body
