Vacuum Cleaner Nozzle Sterilization Chamber for Fast Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners with sterilization functions require slow nozzle movement to ensure sufficient ultraviolet radiation, increasing cleaning time and user inconvenience.
Innovation Solution
A suction nozzle design with a sterilization chamber that uses tangentially directed guide channels to create a whirling air current, allowing prolonged exposure to sterilization units such as UV lamps, heaters, or ozonizers, and a drum brush with antimicrobial coatings for enhanced sterilization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction nozzle is moved quickly relative to the surface to be cleaned, then cleaning efficiency is improved, but the sterilization effect deteriorates because insufficient ultraviolet rays are radiated onto the surface
Solution Approach 1:
The invention transitions from direct surface sterilization to air stream sterilization by introducing a sterilization chamber that processes the air flow containing suspended particles. This dimensional shift allows sterilization to occur in the air path rather than requiring direct contact with the surface, enabling faster nozzle movement while maintaining sterilization effectiveness through prolonged air stream exposure to UV rays within the chamber.
2Reliability
If the suction nozzle is moved slowly to ensure sufficient ultraviolet radiation, then sterilization effect is improved, but cleaning time is increased which reduces productivity
Solution Approach 1:
The sterilization chamber performs preliminary sterilization of the air stream before it contacts the surface. By pre-sterilizing the air containing suspended particles and spores in advance, the system ensures that sufficient UV radiation exposure is achieved during the air flow path, eliminating the need for slow nozzle movement and reducing overall cleaning time while maintaining effective sterilization.
3Device complexity
If the ultraviolet lamp is mounted in the suction nozzle for direct surface sterilization, then the structure is simple, but the sterilization time is insufficient when the nozzle moves quickly
Solution Approach 1:
The invention introduces air as an intermediary medium for sterilization. Instead of directly radiating UV rays onto the surface, the system sterilizes the air stream that carries particles and spores through the sterilization chamber. This intermediary approach extends the sterilization duration by maintaining air flow exposure to UV rays over a longer path, effectively increasing sterilization time without requiring slow nozzle movement.
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
The design enables effective sterilization with reduced cleaning time by maintaining air exposure to sterilization units for a longer duration, improving user convenience and sterilization performance.
Implementation Method 1
Such a vacuum cleaner typically radiates ultraviolet rays onto the surface to be cleaned with an ultraviolet lamp mounted in a suction nozzle (or a suction brush), thereby sterilizing the surface to be cleaned.
Implementation Method 2
The guide channel may be disposed in a tangential direction with respect to the sterilization chamber.
Implementation Method 3
a drum brush with antimicrobial coatings for enhanced sterilization efficiency

AI summary
A suction nozzle for use in a vacuum cleaner includes a suction opening through which air is drawn in from a surface to be cleaned, a sterilization chamber having at least one inlet and at least one outlet, the sterilization chamber being in fluid communication with the suction opening through the at least one inlet, and a sterilization unit disposed in the sterilization chamber to sterilize the air drawn into the sterilization chamber. The air drawn into the sterilization chamber revolves while moving from the at least one inlet to the at least one outlet.
