Aroma Diffuser Dual Backflow Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump type aroma diffusers face issues with smooth aroma diffusion and efficient backflow of essential oil, as the single channel used for both processes leads to air bubbles blocking airflow and liquid accumulation, resulting in ineffective aromatherapy, waste of essential oil, and environmental pollution.
Innovation Solution
A pump type aroma diffuser design featuring a gasification assembly with an air nozzle and essential oil nozzle, interconnected with a guide assembly that includes two asymmetric intake backflow channels to prevent blockages and facilitate easy return of essential oil to the bottle, along with a gasification cavity cover for smooth aroma diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single channel is used for both diffusion of aerial fog and backflow of liquid, then the device structure is simple, but air bubbles block the air inlet and liquid accumulates near the fog outlet
Solution Approach 1:
The single channel is segmented into two separate channels: a first channel for diffusion of aerial fog and a second channel for backflow of liquid essential oil. This segmentation resolves the contradiction by allowing each channel to perform its specific function independently, preventing air bubbles from blocking the air inlet and preventing liquid accumulation near the fog outlet.
2Device complexity
If a single channel is used for both diffusion and backflow, then the device structure is simple, but liquid accumulates and overflows from the aroma diffuser
Solution Approach 1:
The channel is divided into separate pathways: the first channel handles aerial fog diffusion while the second channel handles liquid backflow. This prevents liquid accumulation and overflow by providing a dedicated return path for condensed essential oil, eliminating the harmful effect of liquid overflow while maintaining structural simplicity.
3Device complexity
If air bubbles block the air inlet, then the device structure remains simple, but aerial fog fails to be exhausted
Solution Approach 1:
By segmenting the channel into a first channel for aerial fog diffusion and a second channel for liquid backflow, the system prevents air bubbles from blocking the air inlet. The separate liquid backflow channel allows condensed essential oil to return without interfering with the air inlet, maintaining continuous and efficient aroma diffusion.
4Device complexity
If liquid flows back due to airflow action, then the device structure is simple, but liquid accumulates near the fog outlet
Solution Approach 1:
The segmentation of channels creates a dedicated second channel for liquid backflow that directs condensed essential oil away from the fog outlet area. This prevents liquid accumulation near the fog outlet by providing a separate return pathway, while the first channel maintains proper liquid distribution for continuous diffusion.

AI summary
The present invention provides a pump type aroma diffuser including an essential oil bottle for containing essential oil and a gasification assembly connected with an open end of the essential oil bottle. The gasification assembly includes a gasification cavity, as well as an air nozzle and an essential oil nozzle which are installed on the cavity wall of the gasification cavity. The air nozzle and the essential oil nozzle are interconnected with the gasification cavity. The pump type aroma diffuser also includes a guide assembly which covers the gasification cavity and is configured to guide aroma. The guide assembly has a concentrated fog outlet for exhausting aroma, a first intake backflow channel and a second intake backflow channel which extend from the concentrated fog outlet to two different directions. The tail ends of the first intake backflow channel and the second intake backflow channel extend into the gasification cavity.
