Portable Nebulizer Dust Shield Sliding Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nebulizers face issues with dust accumulation in the nozzle hole and atomizer, leading to reduced atomization performance over time due to residual mist and environmental contamination.
Innovation Solution
A portable nebulizer equipped with a dust shield that is movable between a dust protection position to shield the nozzle hole and an open position to allow mist dispersion, using a sliding sleeve or pivotally connected dust protection sheet to prevent dust adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nebulizer is used for atomization, then the atomizer can generate mist effectively, but dust accumulates in the nozzle hole and on the atomizer plate, degrading performance over time
Solution Approach 1:
A dust shield is provided that can be positioned in advance to cover the nozzle hole and protect the atomizer plate from dust accumulation before contamination occurs. The shield is configured to prevent dust from adhering to the atomization components during storage or when not in use, thereby maintaining atomization performance without requiring frequent cleaning or replacement.
2Object-affected harmful factors
If a dust shield is added to protect the nozzle hole, then dust accumulation is prevented, but the device structure becomes more complex
Solution Approach 1:
The dust shield is designed as a thin, flexible component that can elastically deform during insertion and removal operations. This flexibility allows the shield to adapt to the nozzle hole geometry and facilitates easy installation and removal without requiring complex mechanisms, thereby minimizing the increase in device complexity while still providing effective dust protection.

AI summary
A portable nebulizer includes a nebulizer body including a nozzle hole and an atomizer plate positioned in the nozzle hole, and a dust shield coupled to the nebulizer body and movable relative to the nebulizer body between a dust protection position where the dust shield shields the nozzle hole of the nebulizer body and an open position where the dust shield is kept away from the nozzle hole of the nebulizer body, thus, the dust shield is capable of protecting the nozzle hole of the portable nebulizer against environmental contamination.
