Humidifier UV Sterilizer With Reflector for Uniform Light Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional humidifiers face issues with poor cleanliness due to stagnant water and inadequate uniformity in ultraviolet sterilization, leading to contaminated air and incomplete sterilization of the humidification device.
Innovation Solution
A humidifier design that incorporates a sterilizer with a reflector to ensure uniform diffusion of ultraviolet light within the humidification chamber, improving hygiene and sterilization efficiency by irradiating the internal space with UV light and using a chrome-plated reflector for enhanced light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an ultraviolet sterilizer is installed inside the humidification device, then sterilization function is improved, but uniform diffusion of ultraviolet light throughout the device is insufficient
Solution Approach 1:
A reflector is introduced as an intermediary component between the ultraviolet sterilizer and the humidification chamber walls. The reflector receives ultraviolet light from the sterilizer and redirects it to areas that would otherwise receive insufficient illumination, ensuring uniform distribution of UV light throughout the entire humidification device including corners and distant surfaces.
Solution Approach 2:
The reflector is positioned at specific angles and orientations to redirect ultraviolet light in multiple directions. By changing the spatial dimension of light propagation through strategic placement of reflective surfaces, the system achieves comprehensive coverage of all internal surfaces of the humidification chamber.
2Device complexity
If stagnant water remains in the humidification device, then device structure is simple, but cleanliness and air quality deteriorate
Solution Approach 1:
The ultraviolet sterilizer is activated to perform preliminary sterilization of the water reservoir and humidification chamber before water stagnation can lead to contamination. This preventive action eliminates bacteria and pathogens in advance, ensuring that even if water remains stagnant, it does not become a source of air contamination.
Solution Approach 2:
The system uses its own ultraviolet sterilizer component to automatically sterilize its internal water storage and humidification areas. The sterilizer operates periodically or continuously to maintain cleanliness without requiring external intervention or complex additional cleaning mechanisms.
