Multi-oil Diffuser Reflux Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional essential oil atomizers inefficiently distribute and atomize essential oils due to the formation of large droplets, leading to waste and reduced filtration efficiency, especially with high viscosity oils, as they are difficult to draw through tubes and are less effectively atomized by airflow.
Innovation Solution
The airflow-guided essential oil reflux-type atomizer incorporates a filter atomization mechanism with a guide board and filter housings to recycle larger droplets, re-atomize smaller droplets, and uses a heater to raise the oil temperature for improved atomization, reducing waste and enhancing filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional atomizers are used to atomize essential oils, then the atomization process is simple, but large droplets are formed leading to waste and reduced filtration efficiency
Solution Approach 1:
The patent implements a reflux mechanism that recycles larger droplets back into the atomization chamber for re-atomization. The filter housing collects oversized droplets that would otherwise be wasted, and the reflux port returns them to the atomizer nozzle assembly for further processing into finer, usable particles.
Solution Approach 2:
The patent introduces a heater element that raises the temperature of the essential oil before atomization. This parameter change reduces the oil's viscosity and promotes the formation of smaller, more uniform droplets, thereby improving atomization efficiency and reducing waste.
2Adaptability or versatility
If high viscosity essential oils are used, then a wider variety of oil types can be diffused, but they are difficult to draw through tubes and are less effectively atomized
Solution Approach 1:
The heater element raises the temperature of high viscosity oils, reducing their viscosity and making them easier to pump through the system and atomize effectively. This allows the device to handle diverse oil types including thick, viscous essential oils.
Solution Approach 2:
The system pre-heats the essential oil before it enters the atomization chamber, preparing it in advance for easier flow through the pump and nozzle assembly. This preliminary heating action eliminates flow resistance issues associated with viscous oils.
3Loss of substance
If a filter mechanism is added to recycle droplets, then waste is reduced, but the device complexity increases
Solution Approach 1:
The patent combines the filtration and atomization functions into a single integrated assembly. The filter housing, reflux port, and atomizer nozzle assembly work together as one unit, reducing the need for separate components and simplifying the overall device structure despite the added functionality.
Solution Approach 2:
The atomizer nozzle assembly serves multiple functions: it atomizes the essential oil, directs the atomized stream, and facilitates the reflux of larger droplets. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity.

AI summary
An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow. A heater is used to raise the temperature of the oil where it is atomized, either by heating the oil itself or by heating the gas flowing into the oil. Thus, the atomizer can have improved performance, especially with essential oils having high viscosity and molecular weight.
