Ultrasonic Atomizer Ceramic Wick for Stable E-Liquid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizers face issues with e-liquid guide cotton being affected by temperature changes, leading to unstable e-liquid flow rates and immersion of the atomization piece, causing inefficiencies and user inhalation of e-liquid droplets.
Innovation Solution
The ultrasonic atomizer employs a combination of e-liquid guide ceramic and cotton, where the ceramic has stable micropores and is directly connected to the e-liquid bin, ensuring consistent e-liquid flow despite temperature variations, while the cotton provides flexible support to the atomization piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If e-liquid guide cotton is used to guide e-liquid, then e-liquid can be delivered to the atomization piece, but the e-liquid guide rate increases excessively when temperature increases, causing the atomization piece to be immersed in e-liquid
Solution Approach 1:
The e-liquid guide assembly is divided into two distinct components: an upper e-liquid guide ceramic and a lower e-liquid guide cotton. The ceramic component with stable micropores controls the e-liquid guide rate, while the cotton component provides supplementary guidance. This segmentation allows the stable ceramic structure to prevent excessive e-liquid flow when temperature increases, thereby preventing atomization piece immersion.
Solution Approach 2:
The invention combines two different materials (ceramic and cotton) with different properties to create a composite e-liquid guide assembly. The ceramic material provides thermal stability and consistent porosity, while the cotton material provides flexibility and additional e-liquid guidance capability. This composite structure leverages the advantages of both materials to maintain stable e-liquid flow rates under temperature variations.
2Quantity of substance
If e-liquid guide cotton absorbs e-liquid, then e-liquid is delivered to the atomization piece, but the pore size increase with temperature leads to increased e-liquid guide rate and atomization piece immersion
Solution Approach 1:
Different regions of the e-liquid guide assembly have different properties: the upper ceramic region has stable, temperature-resistant micropores with consistent size, while the lower cotton region has flexible pores that can expand or contract. By placing the stable ceramic component in the upper position where it directly contacts the e-liquid bin, the system ensures that the primary e-liquid flow path maintains stable pore dimensions regardless of temperature changes.
3Speed
If e-liquid viscosity decreases with temperature increase, then e-liquid flows more easily, but the e-liquid guide rate on e-liquid guide cotton increases excessively
Solution Approach 1:
The e-liquid guide ceramic acts as an intermediary component between the e-liquid bin and the e-liquid guide cotton. It regulates the e-liquid flow by providing a stable micropore structure that controls the guide rate, preventing the excessive flow that would otherwise occur when e-liquid viscosity decreases with temperature increase.

AI summary
The present invention relates to an electronic cigarette set, in particular to an ultrasonic atomizer, comprising an e-liquid guide assembly (2); the e-liquid guide assembly comprises an e-liquid guide ceramic (21) which makes direct contact with an e-liquid, e-liquid guide cotton (22) which is located below the e-liquid guide ceramic and is contactingly connected to a surface of the e-liquid guide ceramic, and springs (23) which are located between the e-liquid guide ceramic and the e-liquid guide cotton and abut the e-liquid guide cotton against an atomization piece (322). The e-liquid guide ceramic is a solid ceramic body, and micropores which are used for conducting the e-liquid and vapor are integrally formed on the e-liquid guide ceramic. The present invention uses a combination of an e-liquid guide ceramic and e-liquid guide cotton to guide an e-liquid. In an ultrasonic atomization process, the e-liquid guide amount of the e-liquid guide assembly is fixed, such that the atomization efficiency of ultrasonic atomization is high, the amount of vapor is stable, and atomization not being enough to absorb e-liquid drops due to an ultrasonic atomization piece being soaked in e-liquid or the ultrasonic atomization piece being dry-burnt due to a small amount of e-liquid is avoided.
