Atomizer Capillary Gap for Liquid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic atomizing devices, when the e-liquid level is lower than the oil inlet, it cannot enter the atomizing core, leading to potential burning of the core and e-liquid wastage.
Innovation Solution
A liquid storage assembly with a capillary gap between the inner and outer walls of the atomizing core assembly ensures that e-liquid can enter the atomizing core even when the level is below the inlet, improving utilization and preventing dry burning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the oil inlet is arranged in the middle or upper end of the atomizing core, then the structure is simple and easy to manufacture, but when the e-liquid level is lower than the inlet position, the e-liquid cannot enter the atomizing core, causing dry burning and waste
Solution Approach 1:
The patent introduces a capillary gap between the inner wall and outer wall of the atomizing core assembly, creating a new dimensional pathway for liquid flow. This capillary channel allows e-liquid to reach the heating element from lower levels, resolving the contradiction by adding a vertical dimension solution to a horizontal positioning problem.
Solution Approach 2:
The patent replaces the gravity-dependent liquid delivery system with a capillary action-based system. Instead of relying on liquid level height and gravity to deliver e-liquid to the inlet, the capillary gap provides a passive, automatic liquid transport mechanism that works regardless of liquid level position, eliminating dry burning risk.
2Device complexity
If the oil inlet is positioned at the middle or upper end of the atomizing core, then the device structure is simplified, but e-liquid below the inlet level cannot be utilized, leading to substance loss
Solution Approach 1:
By creating a capillary gap between the inner and outer walls of the atomizing core assembly, the patent adds a vertical liquid transport pathway that enables e-liquid from lower levels to reach the heating element, thereby utilizing previously wasted liquid and reducing substance loss.
Solution Approach 2:
The capillary gap structure enables self-service liquid delivery, where the e-liquid automatically flows through the capillary channel to the heating element without requiring external pumping or complex control mechanisms, ensuring complete utilization of available e-liquid.
3Reliability
If a capillary gap is added between the inner wall and outer wall of the atomizing core assembly, then e-liquid can enter the core even when level is low, but the device structure becomes more complex
Solution Approach 1:
The inner wall is designed as a thin-walled structure that forms a capillary gap with the outer wall. This thin-film approach creates the necessary capillary channels without adding significant structural complexity, as the gap itself becomes the functional element rather than requiring separate components.
Solution Approach 2:
The inner wall is nested within the liquid storage cavity, and the capillary gap is formed between this inner wall and the outer wall of the atomizing core assembly. This nested arrangement integrates multiple functions (liquid storage, capillary action, structural support) into a compact configuration, minimizing overall complexity.
