Electronic Cigarette Assembly for Leak-Controlled Liquid Refill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable electronic cigarettes have a small liquid capacity and short usage time, failing to meet user needs for extended usage.
Innovation Solution
An electronic cigarette assembly comprising an electronic cigarette body with a storage chamber and an expandable tobacco liquid bottle, where a movable part opens liquid passing holes upon assembly, allowing tobacco liquid to be absorbed by liquid absorbing cotton, and includes sealing rings and guiding cotton to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an expanded tobacco liquid bottle is added to increase liquid capacity, then the service life is prolonged, but the device complexity increases
Solution Approach 1:
The expanded tobacco liquid bottle is sleeved on the outer side of the storage chamber, with the storage chamber placed inside the perforating hole of the bottle. This nested structure allows the bottle to expand liquid capacity while maintaining a compact form factor and avoiding excessive complexity.
Solution Approach 2:
The liquid storage system is divided into two independent parts: the original storage chamber with first liquid absorbing cotton, and the expandable bottle with second liquid absorbing cotton. This segmentation allows flexible capacity expansion while keeping each component relatively simple in structure.
2Quantity of substance
If liquid passing holes are opened for refilling, then the liquid capacity is increased, but liquid leakage may occur
Solution Approach 1:
The movable part preliminarily covers the second liquid passing holes to prevent leakage during transport and storage. When the bottle is assembled with the electronic cigarette body, the movable part automatically moves to open the holes, allowing liquid to flow only when intended.
Solution Approach 2:
The first liquid absorbing cotton acts as an intermediary between the first liquid passing hole and the storage chamber interior, controlling liquid flow. Similarly, the second liquid absorbing cotton controls flow from the bottle, preventing uncontrolled leakage while enabling refilling.
3Quantity of substance
If the storage chamber is opened for refilling, then the liquid capacity can be increased, but the ease of operation deteriorates
Solution Approach 1:
The expanded tobacco liquid bottle is designed as a self-contained refillable unit that can be attached to the electronic cigarette body without opening the storage chamber. The bottle automatically connects to the liquid passage system through the movable part mechanism, allowing users to refill liquid simply by attaching the bottle rather than disassembling the device.
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 increases the tobacco liquid capacity and prolongs the service life of the electronic cigarette by allowing for refilling without opening the storage chamber, while preventing liquid leakage.

AI summary
An electronic cigarette assembly includes an electronic cigarette body (200) and an expanded tobacco liquid bottle (100). The electronic cigarette body includes a storage chamber (222). The storage chamber is provided with first liquid absorbing cotton (223) and a first liquid passing hole (226). The expanded tobacco liquid bottle stores tobacco liquid and is provided with second liquid passing holes (125) and a movable part (150). When the expanded tobacco liquid bottle is not assembled with the electronic cigarette body, the movable part covers the second liquid passing holes to prevent the tobacco liquid from flowing out of the second liquid passing holes. When the expanded tobacco liquid bottle is assembled with the electronic cigarette body, the movable part moves to open the second liquid passing holes, allowing the tobacco liquid to pass through the second liquid passing holes and the first liquid passing hole to be adsorbed by the first liquid absorbing cotton.
