Essential Oil Atomizer with Reflux Filter Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional essential oil atomizers produce large droplets leading to inefficient distribution and waste, with filters often becoming blocked due to accumulated droplets when moved or tilted, reducing filtration efficiency.
Innovation Solution
The airflow-guided essential oil reflux-type atomizer incorporates a filter atomization mechanism with successive filter housings that recycle larger droplets and re-atomize smaller ones, combined with sealing valves and a guide board to prevent leakage and improve portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional atomizers are used to atomize essential oils, then the atomization function is provided, but large droplets are produced leading to inefficient distribution and waste
Solution Approach 1:
The atomizer divides the essential oil stream into smaller droplets through a multi-hole nozzle structure, creating fine mist rather than large droplets. The nozzle contains multiple holes of different sizes that segment the oil flow into numerous small particles for efficient distribution.
Solution Approach 2:
The patent employs nozzles with holes of different sizes at different locations to create varying droplet characteristics. The first nozzle has a first hole and the second nozzle has a second hole with different dimensions, allowing local optimization of atomization quality for different distribution requirements.
2Reliability
If filters are added to capture droplets, then filtration is provided, but filters become blocked due to accumulated droplets when moved or tilted, reducing filtration efficiency
Solution Approach 1:
The patent positions the nozzle assembly to direct atomized oil upward against gravity, creating a vertical flow path that prevents droplet accumulation on filters. The outlet is configured to discharge upward, utilizing the vertical dimension to overcome the filter blocking problem caused by gravity-induced droplet settlement.
Solution Approach 2:
The design extracts the nozzle assembly as a separate, replaceable component that can be easily removed and cleaned. This allows the nozzle to be taken out for maintenance when clogged, preventing filter blocking issues without requiring complex integrated filtration systems.
3Ease of operation
If sealing valves and guide boards are added, then portability and leakage prevention are improved, but device complexity increases
Solution Approach 1:
The guide board is integrated with the housing structure, merging the guiding function into the existing housing rather than adding a separate component. The housing itself is designed to guide oil flow, combining structural support with flow guidance to maintain portability without excessive complexity.
Solution Approach 2:
The valve assembly is designed to be automatically actuated by the user's filling action, eliminating the need for separate manual valve control. When the user inserts the oil bottle and presses down, the valve automatically opens and closes, providing self-service functionality that improves ease of operation without adding complex control mechanisms.
