Solution Overview
Problem
Existing cleaning robots mix clean water and sewage during the cleaning process, reducing their effectiveness and making the rollers dirty, which hampers their cleaning ability.
Innovation Solution
A cleaning device with a flexible roller, a roller motor, a pressing member to deform the roller, and separate clean water and sewage sinks, where the clean water flows onto the roller through a clean water hole and the sewage is pressed out through a sewage hole into a sewage sink, ensuring separation and easy cleaning of the roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If clean water and sewage are mixed in the same tank during cleaning, then the device structure is simple, but the roller becomes dirty and cleaning ability is reduced
Solution Approach 1:
The single water tank is divided into two separate tanks: a clean water tank and a sewage tank. This segmentation allows clean water to be supplied to the roller for cleaning while sewage is collected separately, preventing the roller from becoming dirty and maintaining its cleaning ability.
Solution Approach 2:
Sewage is extracted and separated from the cleaning system by providing a dedicated sewage collection tank. The sewage discharge hole in the roller connects directly to the sewage tank, removing contaminated water from the cleaning process and preventing it from recontaminating the roller.
2Reliability
If the roller is continuously cleaned with water, then the roller remains clean and maintains cleaning ability, but clean water is consumed and mixed with sewage
Solution Approach 1:
The water management system is segmented into clean water supply and sewage collection pathways. Clean water flows through the clean water tank and clean water hole to the roller, while sewage is separately collected through the sewage tank and sewage discharge hole, enabling continuous roller cleaning without mixing clean water with sewage.
Solution Approach 2:
The clean water tank acts as an intermediary reservoir that continuously supplies fresh water to the roller through the clean water hole, enabling sustained cleaning operation without directly mixing with the sewage collection system.
3Shape
If the roller structure is rigid, then it maintains shape for effective cleaning, but it is difficult to deform for pressing out sewage
Solution Approach 1:
The roller is designed with a flexible structure that can dynamically change its properties. During normal rotation, the roller maintains sufficient rigidity for cleaning. During sewage discharge, the roller can be pressed by the pressing member to deform temporarily, allowing sewage to be expressed through the discharge hole, then returns to its original shape.
Solution Approach 2:
The roller's physical state is changed by applying pressure through the pressing member. The pressing force temporarily alters the roller's rigidity parameter, enabling it to deform and press out sewage through the discharge hole, after which the roller returns to its normal rigid state for continued cleaning operation.

AI summary
The disclosure relates to a sweeping robot and a cleaning device. The sweeping robot includes: a flexible roller for cleaning the ground, a roller motor for driving the flexible roller to rotate, a pressing member for deforming the flexible roller to press out sewage. Clean water in the clean water sink flows through the clean water hole to the flexible roller. The sweeping robot further includes a sewage sink. The sewage sink is provided with a sewage hole is adjacent to the pressing member. The pressing member deforms the flexible roller, causing sewage to be pressed out of the flexible member and flow through the sewage hole into the sewage sink. The sewage sink is separated from the clean water sink. The cleaning device of the present invention has strong cleaning ability, and the flexible roller is easy to clean.
