Scrubbing brush and scrubber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scrubbers experience insufficient suction in the front and rear flow-guiding channels, leading to sewage water flowing back to the ground, which necessitates secondary cleaning and reduces user experience.
Innovation Solution
The implementation of a scrubber design with a front suction port and a rear suction port, along with intersecting central axes in the flow-guiding channels, and a water storage groove in the rear flow-guiding channel, to enhance suction efficiency and prevent sewage water from flowing back to the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single main suction port is used to adsorb sewage water from both front and rear flow-guiding channels, then the structure is simple, but suction loss occurs and sewage water flows back to the ground
Solution Approach 1:
The single main suction port is segmented into two separate suction ports: a front suction port for the front flow-guiding channel and a rear suction port for the rear flow-guiding channel. This segmentation allows each channel to have dedicated suction capability, preventing suction loss and backflow while maintaining reasonable structural complexity.
2Device complexity
If the central axes of front and rear flow-guiding channels are parallel, then the structure is simple, but suction efficiency is insufficient
Solution Approach 1:
The central axes of the front and rear flow-guiding channels are configured to be asymmetric and intersecting rather than parallel. The front flow-guiding channel's central axis and rear flow-guiding channel's central axis intersect within the front flow-guiding channel, creating asymmetric flow paths that improve suction efficiency and prevent backflow.
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
This design effectively reduces suction loss and prevents sewage water from returning to the ground, improving the efficiency of sewage water collection and enhancing user experience by ensuring that sewage water is directed into the main suction port.
Implementation Method 1
The main suction port is to adsorb sewage water from the front flow-guiding channel and the rear flow-guiding channel through a vacuum adsorption machine

AI summary
A scrubber includes: a main scrubber body; a scrubbing brush including a front cleaning brush and a rear cleaning brush; a front suction port facing toward the front cleaning brush and a rear suction port facing toward the rear cleaning brush; a front flow-guiding channel in communication with the main suction port and the front suction port; and a rear flow-guiding channel in communication with the main suction port and the rear suction port. A central axis of the front flow-guiding channel and a central axis of the rear flow-guiding channel intersect in the front flow-guiding channel.
