Cleaning device for cleaning mopping cloth of self-propelled cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-propelled cleaning robots cannot automatically clean their mopping cloths, leading to a degradation of their cleaning performance over time and requiring manual intervention for maintenance.
Innovation Solution
A cleaning device with a clean water tank, waste-water tank, base, cleaning unit, clean water pipeline, and waste-water pipeline that allows for automatic cleaning of the mopping cloth, using a movable cleaning unit with brushes and a drainage system to collect and recycle cleaning liquid, preventing dust from accumulating on the device's base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning robot performs wet cleaning with a mopping cloth, then the cleaning function is enhanced, but the mopping cloth accumulates stains and dust requiring manual cleaning or replacement
Solution Approach 1:
The cleaning robot autonomously cleans its own mopping cloth by retracting it into the base, spraying cleaning liquid, and using a rotating brush to scrub the cloth. The dirty water is then suctioned back into the base for disposal, completing a self-service cleaning cycle without human intervention.
Solution Approach 2:
The patent combines multiple functions (water spraying, brush rotation, suction) into an integrated cleaning system within the base. The clean water tank, waste water tank, brush assembly, and suction system work together as a unified automatic cleaning mechanism.
2Reliability
If manual cleaning of the mopping cloth is performed, then the cleaning robot's performance is maintained, but the automatic cleaning capability is degraded
Solution Approach 1:
The system achieves full automation by enabling the robot to clean its own mopping cloth through an integrated system that includes automatic retraction, water spraying, brush agitation, and suction of dirty water, eliminating the need for manual intervention entirely.
Solution Approach 2:
The cleaning base is pre-equipped with all necessary components (clean water tank, waste water tank, brush assembly, suction system) before the robot returns, allowing immediate automatic cleaning operation without requiring setup or manual preparation.
3Reliability
If cleaning liquid is sprayed during mopping cloth cleaning, then cleaning effectiveness is improved, but cleaning liquid may leak from the cleaning chamber
Solution Approach 1:
The cleaning chamber is designed with a recessed bottom that forms a collection space before the drainage hole. This pre-cushioning design captures cleaning liquid and prevents it from leaking outward, containing any potential spillage within the chamber structure.
Solution Approach 2:
The recessed bottom structure acts as an intermediary between the water spraying system and the drainage hole, providing a transition zone that collects and redirects cleaning liquid flow to prevent leakage while maintaining effective cleaning action.
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
Enables the automatic cleaning of dirty mopping cloths, reducing the need for manual intervention and enhancing the cleaning robot's performance by maintaining cleanliness without manual intervention.
Implementation Method 1
The water outlet is configured to spray a cleaning liquid toward a direction away from the base
Implementation Method 2
The bottom of the cleaning chamber is provided with a drainage hole, which communicates with the waste-water pipeline and is configured to discharge the cleaning liquid

AI summary
The present invention relates to a cleaning device for cleaning a mopping cloth of a self-propelled cleaning apparatus. The cleaning device includes a clean-water tank, a waste-water tank, a base, a cleaning unit, a clean-water pipeline and a waste-water pipeline. The cleaning unit includes a water outlet, a cleaning brush and a cleaning chamber. The water outlet is configured to spray a cleaning liquid toward a direction away from the base. The cleaning brush cleans a mopping cloth. The clean-water pipeline communicates between the clean-water tank and the water outlet and is for the cleaning liquid in the clean-water tank to pass through the clean-water pipeline and be sprayed from the water outlet. The waste-water pipeline communicates between the waste-water tank and the cleaning chamber of the cleaning unit and is for the cleaning liquid sprayed while the cleaning unit cleans the mopping cloth to pass through the waste-water pipeline and be collected in the waste-water tank.
