Modular Liquid-Tank Electronic Cigarette for Extended Puffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable electronic cigarettes have a fixed capacity and battery life, leading to insufficient puffs due to the inability to expand the tobacco liquid, which affects their service life and fails to meet user needs.
Innovation Solution
The electronic cigarette design includes a main body with an installation chamber for multiple non-detachable or detachable liquid storage tanks, each with a liquid outlet hole, and a sealing mechanism to increase tobacco liquid capacity and ensure stability during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the tobacco liquid capacity is increased by adding multiple liquid storage tanks, then the total number of puffs and service life are improved, but the device complexity and structural complexity increase
Solution Approach 1:
The liquid storage system is divided into multiple independent liquid storage tanks (first liquid storage tank, second liquid storage tank, etc.) that can be separately installed in the installation chamber. Each tank has its own liquid outlet hole that communicates with the liquid storage chamber, allowing the total liquid capacity to be expanded through modular addition rather than requiring a single large complex reservoir.
Solution Approach 2:
The installation chamber is designed as a universal mounting space that can accommodate one or multiple liquid storage tanks. The chamber includes an insertion hole with sealing structure that can receive different numbers and types of liquid storage tanks, providing flexibility in configuration while maintaining a unified structural framework that reduces overall device complexity.
2Quantity of substance
If multiple liquid storage tanks are installed in the installation chamber, then the tobacco liquid storage capacity is enhanced, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The liquid storage function is segmented into multiple independent tanks that can be manufactured separately using standardized processes. Each tank is a discrete component with a consistent structure (body, outlet hole, insertion end), allowing for simplified manufacturing and quality control compared to a single complex multi-chamber reservoir.
Solution Approach 2:
Multiple liquid storage tanks are nested within the installation chamber of the main body, with each tank's insertion end fitting into the insertion hole. This nested arrangement allows compact integration of multiple storage units without requiring proportionally increased overall device volume, and the standardized insertion interface simplifies assembly procedures.
3Adaptability or versatility
If the liquid storage tanks are made detachable for user customization, then the adaptability and user flexibility are improved, but the reliability and sealing performance may deteriorate
Solution Approach 1:
The liquid storage tanks are designed with detachable insertion ends that can be dynamically installed or removed from the installation chamber's insertion hole. This dynamic configuration allows users to customize the number of tanks according to their needs while maintaining a standardized mechanical interface that ensures reliable reconnection and sealing each time a tank is attached.
Solution Approach 2:
A sealing ring is introduced as an intermediary component between the liquid storage tank's insertion end and the insertion hole. This sealing element mediates the connection, ensuring liquid-tight sealing while allowing for easy attachment and detachment. The sealing ring compensates for minor dimensional variations and maintains reliable sealing performance across multiple assembly cycles.

AI summary
An electronic cigarette includes a main body of electronic cigarette (10), and a plurality of liquid storage tanks (2) for storing tobacco liquid. The main body of electronic cigarette is provided with a liquid storage chamber (133) for storing tobacco liquid and at least one installation chamber (123) for installing the liquid storage tanks. One side of the installation chamber is a first opening (124). Each liquid storage tank is installed corresponding to one installation chamber, or the installation chamber is used for accommodating at least two liquid storage tanks. Each liquid storage tank is equipped with a liquid outlet hole (22) for liquid discharge. The liquid storage tanks are at least partially installed in the installation chamber, and the liquid outlet hole is in communication with the liquid storage chamber, thereby increasing a capacity of the electronic cigarette to store tobacco, increasing puffs for users, and improving a service life of the electronic cigarette.
