Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizers face issues of slow e-liquid supply leading to dry burning of the atomizing sheet and e-liquid inhalation due to direct communication between the air pipe and atomization cavity.
Innovation Solution
An electronic cigarette atomizing core design featuring an outer and inner sleeve with e-liquid guide cotton sandwiched between them, air inlet grooves aligned with e-liquid flow, and airflow-enhanced e-liquid delivery to prevent dry burning and e-liquid inhalation, utilizing air pressure to increase e-liquid flow speed and ensure continuous supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If e-liquid supply speed is increased to prevent dry burning, then atomizing sheet continuous operation is improved, but e-liquid may be inhaled through air pipe
Solution Approach 1:
The device divides the internal structure into separate functional zones: an atomization cavity for ultrasonic atomization and an e-liquid supply channel isolated from the air flow path. This segmentation allows fast e-liquid supply without direct communication between e-liquid reservoir and air outlet, preventing inhalation while ensuring continuous atomization.
Solution Approach 2:
The patent introduces an e-liquid guide cotton as an intermediary component between the e-liquid tank and atomization sheet. This cotton wick serves as a mediator that transports e-liquid through capillary action, enabling controlled supply speed increase without direct e-liquid exposure to the air flow path, thus preventing inhalation.
2Productivity
If air flow speed is increased to enhance atomization, then atomization efficiency is improved, but e-liquid guide cotton adhesion resistance increases
Solution Approach 1:
The patent utilizes pneumatic pressure differential created by air flow through the atomization cavity. The pressure difference generated by air movement acts on the e-liquid in the guide cotton, helping to overcome adhesion forces and maintain continuous e-liquid supply even at high atomization speeds.
Solution Approach 2:
The device changes the physical parameters of e-liquid delivery by utilizing pressure differential and capillary action dynamics. As air flow speed increases, the pressure differential changes to dynamically balance adhesion forces, allowing the system to maintain efficient atomization without e-liquid supply interruption.
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
Enhances e-liquid delivery speed, prevents dry burning of the atomizing sheet, and minimizes e-liquid inhalation by optimizing airflow and pressure dynamics within the atomizer.
Implementation Method 1
two ends of e-liquid guide cotton are sandwiched between the outer sleeve and the inner sleeve... While the e-liquid passes through the first e-liquid passing port and is absorbed by the e-liquid guide cotton
Implementation Method 2
the air pressure in the air inlet groove changes with the air flow, so that air pressure in the e-liquid tank is not balanced with air pressure in the air inlet groove... increases the air pressure in the e-liquid tank, and then increases the speed of the e-liquid from the e-liquid tank to the e-liquid guide cotton
Implementation Method 3
During ultrasonic atomization of the existing ultrasonic electronic cigarette atomizer... sufficient e-liquid is supplied for the ultrasonic atomization of the ultrasonic atomizing sheet
