Rotating Nozzle Feeder for Internal Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines are unable to insert a nozzle into the interior spaces of cleaning objects, such as objects with holes, due to the nozzle's design and movement limitations.
Innovation Solution
A cleaning machine design that includes a rotatable table, a movable feeder system, and a nozzle head with a nozzle that can rotate about a vertical axis, allowing the nozzle to be positioned and inserted into internal spaces of cleaning objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nozzle is fixed in a conventional position, then the structure is simple, but the nozzle cannot be inserted into interior spaces of cleaning objects
Solution Approach 1:
The nozzle is made rotatable about a vertical axis and the feeder is made movable in vertical and front-rear directions, transforming the nozzle positioning system from static to dynamic. This enables the nozzle to reach interior spaces of cleaning objects while maintaining structural simplicity through controlled motion rather than complex mechanical linkages
Solution Approach 2:
The nozzle positioning is extended from a single plane to three-dimensional space by adding vertical movement capability to the feeder and rotational capability about a vertical axis. This multi-dimensional positioning allows the nozzle to access interior spaces that would be unreachable with conventional fixed or single-axis positioning
2Adaptability or versatility
If the nozzle is designed for external cleaning only, then the structure is simple, but the cleaning capability for interior spaces is limited
Solution Approach 1:
The feeder system is designed to move the nozzle in vertical and front-rear directions, enabling the nozzle to reach into interior spaces of cleaning objects. This dynamic positioning capability expands cleaning coverage from external surfaces to include internal cavities and holes without requiring multiple nozzles or complex positioning mechanisms

AI summary
Provided is a cleaning machine that allows a nozzle to be inserted into the internal space of the cleaning machine in a simple structure. The cleaning machine includes: a table rotatable about a table axis extending in a vertical direction; a feeder extending in a front-rear direction, the feeder movable only in the vertical direction and the front-rear direction; a nozzle head disposed on the feeder, and a nozzle including an ejection opening facing in a direction different from the table axis, the nozzle disposed on the nozzle head, the nozzle rotatable about a nozzle axis extending in the vertical direction.
