Liquid Reservoir Bubble Blocking Structure for Nebulizer Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebulizers face issues with medicinal liquid bubbles forming during the nebulization process, which cover or remain on detection units, leading to inaccurate liquid level detection and potential damage from continuous operation when the liquid is depleted.
Innovation Solution
A liquid reservoir with a bubble blocking structure, including a partition wall or straight pipe, is designed to collect and isolate bubbles generated during nebulization, preventing them from interfering with the detection module's accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection unit is disposed inside the liquid reservoir to detect the amount of medicinal liquid, then the nebulizing unit can stop operation in advance to prevent damage, but bubbles generated during nebulization cover or remain on the detection unit, affecting sensing accuracy
Solution Approach 1:
The patent introduces a bubble blocking structure as an intermediary element between the nebulizing unit and the detection unit. This structure selectively blocks bubbles from reaching the detection unit while allowing the detection unit to continue monitoring liquid levels accurately. The bubble blocking structure acts as a mediator that filters out the harmful bubble interference without obstructing the detection function.
Solution Approach 2:
The patent segments the liquid reservoir into distinct functional zones by introducing a bubble blocking structure that divides the space between the nebulizing unit and the detection unit. This segmentation creates a bubble-free zone around the detection unit while maintaining the overall integrity of the liquid reservoir and allowing independent operation of each component.
2Productivity
If the nebulizing unit continues to operate when medicinal liquid is depleted, then productivity is maintained, but the nebulizing unit may be damaged
Solution Approach 1:
The patent implements a feedback mechanism where the detection unit continuously monitors the liquid level and provides real-time information to the control unit. When the liquid level reaches a predetermined threshold indicating depletion, the control unit receives this feedback and automatically stops the nebulizing unit, preventing damage while enabling continuous operation during the available liquid period.
Solution Approach 2:
The detection unit is positioned and configured to detect liquid level depletion in advance before it actually occurs. This preliminary detection allows the control unit to stop the nebulizing unit proactively, preventing damage before it can happen while maximizing the productive use of the medicinal liquid.

AI summary
A liquid reservoir includes a liquid storage chamber, a nebulizing module, a detection module, a lid, and a bubble blocking structure. The liquid storage chamber has an opening, and a bottom of the liquid storage chamber has a through hole. The nebulizing module is disposed in the through hole. The detection module is disposed within the liquid storage chamber and adjacent to the through hole. The lid is disposed on the liquid storage chamber and covers the opening. The bubble blocking structure is disposed in the liquid storage chamber, and an orthogonal projection of the bubble blocking structure that is projected to the bottom of the liquid storage chamber at least partially overlaps with the through hole.
