Electronic Cigarette E-Liquid Extruder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from e-liquid quality degradation when not used for a long time due to prolonged exposure of e-liquid to heating elements, affecting taste and performance.
Innovation Solution
An electronic cigarette design featuring an e-liquid extruder with a motor-driven piston that controls e-liquid flow into the heating element, along with a sensor to adjust e-liquid supply based on air flow, ensuring consistent e-liquid quality and taste by regularly replenishing the e-liquid and regulating its flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the heating element remains immersed in e-liquid for long periods, then the heating element is ready for immediate use, but the e-liquid quality degrades and taste deteriorates
Solution Approach 1:
The heating element is extracted from the e-liquid reservoir when not in use. The atomizing assembly can be detached from the battery assembly, removing the heating element from contact with the e-liquid, thereby preventing quality degradation while maintaining readiness for use.
Solution Approach 2:
The system transitions from a static immersion state to a dynamic on-demand state. The heating element is only introduced into the e-liquid immediately before use through assembly detachment, creating a dynamic system that adapts between storage and operation modes to preserve e-liquid quality.
2Productivity
If the e-liquid is continuously supplied to the heating element, then the atomization performance is maintained, but the e-liquid quality degrades over time
Solution Approach 1:
Instead of continuous supply, the e-liquid is supplied periodically only when needed. The system uses on-demand atomization where the heating element is assembled with the reservoir only when the user intends to use the device, creating periodic contact rather than continuous immersion.
Solution Approach 2:
The system provides self-service through immediate assembly before use. The user assembles the atomizing assembly with the battery assembly containing fresh e-liquid right before use, ensuring the heating element receives e-liquid only when needed, eliminating prolonged exposure issues.
3Reliability
If the heating element is kept separate from e-liquid, then e-liquid quality is preserved, but the device requires assembly before use
Solution Approach 1:
The e-liquid is prepared in advance in the battery assembly reservoir, and the atomizing assembly is pre-loaded with the heating element. Both components are ready separately, and assembly before use is a simple preliminary action that ensures quality preservation while maintaining operational readiness.
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
The solution maintains e-liquid quality and taste by regularly replenishing and controlling the e-liquid supply, enhancing user experience and extending the lifespan of the e-liquid, while also providing adjustable power modes and e-liquid flow control.
Implementation Method 1
the heating element comprises a first through hole disposed on the bottom portion and communicating with the e-liquid conduction channel; the heating element further a bottom surface, a peripheral wall, and a plurality of heating wires disposed on the bottom surface and/or the peripheral wall
Implementation Method 2
the heating element is disposed in the first silicone ring to atomize the e-liquid
Implementation Method 3
the piston is movable in the e-liquid tank to extrude the e-liquid out of the e-liquid outlet
Implementation Method 4
the first silicone ring is disposed between the heating element and the base to prevent leakage of the e-liquid
Implementation Method 5
when external air is sucked into the electronic cigarette, the sensor detects air flow to control the amount of the e-liquid supplied
Implementation Method 6
a plurality of heating wires disposed on the bottom surface and/or the peripheral wall

AI summary
An electronic cigarette includes an e-liquid extruder. The e-liquid extruder includes an e-liquid tank, a piston, a push rod, and a motor. The piston is disposed in a bottom opening of the e-liquid tank. The push rod includes an inner wall with a female thread and the rotor includes an outer wall with a male thread. The male thread corresponds to the female thread. The piston is disposed on the push rod; when the motor is energized and rotates, the push rod moves upward to extrude e-liquid out of the e-liquid tank.
