Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nebulizing devices suffer from rapid consumption of scented liquid, inefficient atomization, and adhesive substance buildup that blocks the outlet, leading to ineffective scent diffusion.
Innovation Solution
A nebulizing device design featuring a nozzle with a minimum effective diameter and a suction mouth with a second shrinkage conduit, coupled with a power unit to produce high-speed airflow, creating negative pressure to draw scented liquid as small droplets, and a cleansing mechanism using alcohol to break down adhesive substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If essential oil is drawn to the outlet of the tube using conventional nebulizing devices, then the scented liquid is delivered to the atomization zone, but the adhesive substance of essential oil droplets blocks the outlet of the tube, affecting atomizing effectiveness
Solution Approach 1:
The patent extracts and removes the adhesive substance (essential oil residue) from the tube outlet through a cleaning mechanism. The cleaning assembly includes a cleaning liquid storage chamber and a cleaning liquid delivery structure that flushes the tube outlet to remove accumulated adhesive substances, preventing blockages and maintaining atomizing effectiveness.
Solution Approach 2:
The patent introduces cleaning liquid as an intermediary substance to mediate between the blocked outlet and the essential oil residue. The cleaning liquid acts as a solvent that dissolves and removes the adhesive substance, enabling the tube outlet to function properly again without direct mechanical intervention.
2Productivity
If conventional nebulizing devices atomize scented liquid, then fragrance is diffused, but the consumption of scented liquid is rapid and considerable, leading to inefficient control
Solution Approach 1:
The patent changes the physical parameters of the scented liquid delivery system by implementing a controlled flow rate mechanism. The pump is configured to deliver scented liquid at a specific, optimized flow rate that balances atomization effectiveness with consumption efficiency, preventing excessive usage while maintaining fragrance diffusion.
Solution Approach 2:
The patent applies partial action by delivering only the necessary amount of scented liquid required for effective atomization. Rather than continuous or excessive delivery, the system provides controlled, intermittent dosing that is sufficient for fragrance diffusion but minimizes overall consumption.
3Productivity
If the tube outlet is blocked by adhesive substance, then atomization is affected, but cleaning the outlet is required to maintain atomizing results
Solution Approach 1:
The patent implements self-service by incorporating an automatic cleaning mechanism that periodically or continuously cleans the tube outlet without user intervention. The cleaning assembly automatically delivers cleaning liquid to flush the outlet, allowing the device to maintain its own performance without requiring manual cleaning operations.
Solution Approach 2:
The patent ensures continuity of useful action by implementing a continuous or periodic cleaning function that prevents blockage accumulation rather than merely responding to blockages. The cleaning mechanism operates continuously or at regular intervals to maintain the tube outlet in a clean, functional state, ensuring uninterrupted atomizing performance.
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
The device efficiently atomizes scented liquid, minimizes consumption, and extends scent diffusion time by controlling droplet size and using alcohol to clear blockages, maintaining outstanding atomization results.
Implementation Method 1
The power supplying the gas providing device producing high-pressure airflow passing through the shrunk cross-sectional portion of the first shrinkage conduit, and forming high-speed airflow from the nozzle of the spray head to pass through the above of the suction mouth of the tube to form an area of negative air pressure (such as Bernoulli's principle), therefore the scented liquid (e.g. fragrance oil, essential oil) inside the bottle are being drawn through the second shrinkage conduit to the suction mouth
Implementation Method 2
The nozzle provides continual high-speed airflow which blows scented liquid into vapor
