Cleaner Nozzle Water Drain Layout for Leak-Safe Mop Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner nozzles face issues with water leakage, inefficient water supply to mops, and complex suction path designs, which hinder effective cleaning and foreign matter suction.
Innovation Solution
A cleaner nozzle design featuring a water tank with a drain hole and blocking rib to prevent water leakage, independent driving motors for rotating mops, and a suction flow path that minimizes flow path length and interference, allowing for efficient water supply and foreign matter suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is supplied to the mop through a forward-spraying nozzle, then water can be supplied to the cleaning area, but water may wet nearby structures and the mop cannot sufficiently absorb the water
Solution Approach 1:
The patent extracts the water supply function from a forward-spraying nozzle configuration and relocates it to a drain hole at the bottom of the nozzle housing. This allows water to be discharged directly downward onto the mop rather than spraying forward, eliminating the harmful effect of water wetting nearby structures while ensuring the mop can sufficiently absorb the water.
Solution Approach 2:
The patent introduces a blocking rib as an intermediary structure between the drain hole and the control board. This blocking rib prevents water that leaks into the nozzle housing from reaching the control board, thereby protecting the electrical components while still allowing water to be discharged through the drain hole onto the mop.
2Device complexity
If a single rotation motor is used to drive both rotating bodies, then device complexity is reduced, but reliability decreases and suction path design becomes complicated
Solution Approach 1:
The patent segments the driving system by providing independent rotation motors for each rotating body (first and second rotating bodies) instead of using a single motor. This segmentation improves reliability because if one motor fails, the other can still operate, while also simplifying the suction path design by eliminating the need for a central motor position that would complicate airflow paths.
3Ease of manufacture
If the suction path is designed to avoid interfering with the central rotation motor, then motor installation is facilitated, but the suction path length increases and structure becomes complicated
Solution Approach 1:
By segmenting the driving system into multiple independent motors positioned at different locations, the patent eliminates the need for a central motor position. This allows the suction path to be designed as a simpler, more direct path from the suction port to the cleaner body without needing to route around a centrally located motor, thereby reducing suction path length and structural complexity.

AI summary
A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit. The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit.
