Cleaner Nozzle Water Control for Stable Rotary Mop Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face challenges in effectively drawing in foreign substances on a floor surface, providing stable water supply to rotating cleaning parts, minimizing water leakage, and allowing easy adjustment of water amount during cleaning, while also preventing water from entering the nozzle body and ensuring efficient cleaning performance.
Innovation Solution
A cleaner nozzle design featuring a nozzle body with a suction passage, a rotatable cleaning part with attached rags, a driving device, a separable water tank, and a water supply passage that includes injection nozzles to supply water to the cleaning part, with a water adjuster allowing easy manipulation of water flow using hands or feet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotary motor is used to drive both rotation bodies, then the device complexity is reduced, but the reliability decreases because both rotation bodies may not rotate if the motor fails
Solution Approach 1:
The single rotary motor is divided into two separate rotary motors, with each motor independently driving one rotation body. This segmentation ensures that if one motor fails, the other can still operate, thereby improving reliability while maintaining reasonable device complexity.
2Device complexity
If the suction port body is disposed at a central portion to accommodate one rotary motor, then the device complexity is reduced, but the suction path becomes elongated and more complicated
Solution Approach 1:
The suction port body is divided into a first suction port body and a second suction port body, with each accommodating one rotary motor respectively. This segmentation allows for shorter and simpler suction paths in each unit, avoiding the need for long suction paths that would result from centralizing the motor.
3Ease of operation
If the water injection nozzle sprays water from the front surface of the cleaner body, then the ease of operation is improved, but water may wet other peripheral structures instead of the rag
Solution Approach 1:
The water injection nozzle is specifically positioned to spray water onto the rotation bodies and rags, with the spray direction and location optimized to ensure water is applied only where needed. This local quality approach prevents water from wetting peripheral structures while maintaining ease of operation.
4Device complexity
If the water injection nozzle is disposed at a center of the cleaner body, then the device complexity is reduced, but the water sprayed is not sufficiently absorbed by the rag
Solution Approach 1:
The water injection nozzle is positioned to spray water directly onto the rotation bodies and rags, ensuring localized water application where it is most needed. This positioning maximizes water absorption by the rags while maintaining simple device structure.

AI summary
A nozzle of a cleaner includes a nozzle body, a rotation cleaning part having a rotation plate to which a rag is attached, a driving device provided in the nozzle body, a water tank, a water supply passage, and a water adjuster of which at least a portion is mounted on the nozzle body at a rear side thereof so as to be exposed to a rear surface or a top surface of the nozzle body. A user standing on the same floor surface as the nozzle body may manipulate the water adjuster by using his or her foot. The water adjuster may be configured to adjust an on/off operation and a rotation speed (e.g., rpm) of the pump motor.
