Atomization Device Suction Pump Reverse Flow Blockage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers are prone to blockages due to impurities in essential oils, which disrupt the atomization process as they rely on a siphon principle that requires a highly closed space, making it difficult to prevent impurities from blocking the atomization port.
Innovation Solution
The atomization device employs a suction pump to directly convey substances from a container to a mixing chamber, where high-pressure gas from a gas pump atomizes the liquid, and the suction pump can reverse to remove impurities, creating a larger, less sealed system that reduces blockage probability and allows for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the siphon principle of a gas pump is used to suck essential oil from a container to an atomization port, then the atomization function can be enabled, but impurities of the essential oil easily block the atomization port and the device cannot operate normally
Solution Approach 1:
The patent extracts the harmful impurities from the essential oil by introducing a separate liquid inlet that allows cleaning liquid to enter the atomization chamber. This cleaning liquid flows through the atomization port and carries impurities out through a liquid outlet, effectively separating the harmful substances from the atomization process
Solution Approach 2:
The patent performs preliminary cleaning action by providing a cleaning liquid inlet that can introduce cleaning liquid before atomization operations. This preliminary cleaning prevents impurities from accumulating and blocking the atomization port, maintaining reliable operation
2Reliability
If a highly closed space is used for siphon action, then the atomization process can function, but the atomization space is very small and sealing requirements are very high
Solution Approach 1:
The patent segments the atomization device into distinct functional chambers: an atomization chamber for the actual atomization process, and a liquid inlet system for introducing cleaning liquid. This segmentation allows the atomization chamber to have a larger volume without requiring the entire device to be highly sealed, reducing sealing complexity while maintaining siphon action effectiveness
Solution Approach 2:
The patent introduces cleaning liquid as an intermediary substance that facilitates the removal of impurities. This intermediary liquid allows the system to operate with a more open structure by providing a flushing mechanism that compensates for the reduced sealing requirements
3Reliability
If the suction pump pumps substance back to the container, then impurities can be removed from the atomization port, but the device complexity increases
Solution Approach 1:
The patent makes the suction pump multi-functional by enabling it to operate in two modes: forward pumping to supply liquid to the atomization chamber, and reverse pumping to return liquid and impurities to the container. This universal pump design removes blockages while avoiding the need for separate cleaning mechanisms, managing complexity through functional integration
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
This design significantly reduces the likelihood of blockages and extends the device's service life by allowing continuous operation with reduced noise, as the suction pump only works intermittently, and the reverse suction mechanism effectively clears impurities, ensuring efficient atomization and aroma diffusion.
Implementation Method 1
the suction pump is used for pumping a substance in the container to the mixing chamber or pumping a substance in the mixing chamber back to the container
Implementation Method 2

Implementation Method 3
the high-pressure gas is used for atomizing liquid in the mixing chamber through the atomization port
