Rotatable Vacuum Cleaner Nozzle for Stable Suction Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner nozzles face challenges in effectively cleaning areas where the agitator corresponds to the auxiliary suction port, limiting the cleaning area and suction force distribution.
Innovation Solution
A suction nozzle design featuring a main nozzle with rotatably connected movable nozzles and a rotary cleaning unit, allowing for adjustable suction port positions and maintaining effective cleaning across the entire floor surface through the use of seals and a drive mechanism to ensure consistent suction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the auxiliary nozzle is drawn out of the main nozzle to increase the suction area, then the cleaning area increases, but the floor cleaning performance deteriorates at portions where the agitator corresponds to the auxiliary nozzle
Solution Approach 1:
The auxiliary nozzle is designed to be rotatable relative to the main nozzle, allowing dynamic adjustment of its position. This enables the auxiliary nozzle to be rotated away from the agitator path when the agitator is in use, preventing interference with floor cleaning while maintaining the expanded suction area configuration for other cleaning scenarios
2Adaptability or versatility
If the movable nozzle is rotated to adjust suction port position, then the adaptability improves, but the suction force distribution deteriorates
Solution Approach 1:
The system incorporates seals that maintain a consistent sealing relationship between the movable nozzle and main nozzle regardless of the rotation angle. This ensures that the suction force distribution remains stable and reliable even as the suction port position is adjusted through rotation, allowing parameter change without compromising performance

AI summary
A nozzle for a vacuum cleaner and a vacuum cleaner are provided. The nozzle may include a main nozzle; at least one movable nozzle rotatably coupled to the main nozzle; and a rotary cleaner provided inside of the main nozzle and the movable nozzle that cleans a floor surface using a rotary motion. The rotary cleaner may include a main shaft rotatably provided inside of the main nozzle, and at least one auxiliary shaft provided inside of the movable nozzle and connected to the main shaft. The at least one auxiliary shaft may rotate using a rotational force transmitted from the main shaft.
