Solution Overview
Problem
Existing electronic cigarettes have a small capacity of tobacco liquid, non-replaceable atomizing cores, and carbon deposition on heating elements, leading to a burnt smell and reduced user experience.
Innovation Solution
An electronic cigarette assembly with a detachable atomizing core and a liquid bottle, featuring a first and second liquid storage cavity with communication holes, a detachable connection mechanism, and a covering member that opens to allow liquid transfer when installed, along with a conductive member for electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the atomizing core is made non-replaceable to simplify the device structure, then the device complexity is reduced, but the service life and user experience deteriorate due to carbon deposition on the heating element
Solution Approach 1:
The electronic cigarette is divided into separable modules: a reusable main body and replaceable atomizing cores. This segmentation allows the atomizing core to be replaced when carbon deposition occurs, extending service life while keeping the overall device structure relatively simple.
Solution Approach 2:
The atomizing core is designed as a disposable component that can be discarded after use and replaced with a new one. This approach resolves the contradiction by allowing the heating element to be renewed without replacing the entire device, thus extending service life while maintaining simple device structure.
2Manufacturing precision
If the tobacco liquid capacity is increased by making the liquid non-refillable, then the manufacturing precision and sealing requirements are reduced, but the number of puffs and user experience deteriorate
Solution Approach 1:
The liquid bottle is designed as a sealed, non-refillable component that is discarded after use. Multiple liquid bottles can be used sequentially with each atomizing core. This approach increases the effective number of puffs without requiring complex refilling mechanisms or high sealing precision for user access.
3Duration of action of stationary object
If the atomizing core is made replaceable to extend service life, then the service life and user experience are improved, but the device complexity and connection mechanism requirements increase
Solution Approach 1:
The replaceable atomizing core design segments the device into modular components with simple connection interfaces. This allows for easy replacement while maintaining overall device simplicity, as the connection mechanism only needs to handle basic electrical and mechanical connections.
Solution Approach 2:
The main body is designed with universal connection interfaces that can accommodate different atomizing core models. This universality simplifies the connection mechanism by using standardized interfaces rather than complex model-specific connections, reducing device complexity while enabling replaceability.
4Manufacturing precision
If the liquid bottle is made sealed and non-refillable to simplify manufacturing, then the manufacturing precision is reduced, but the tobacco liquid capacity and number of puffs are limited
Solution Approach 1:
The sealed liquid bottle is designed as a disposable component that is discarded after the liquid is depleted. This approach allows for larger liquid capacity in each bottle without requiring complex refilling mechanisms, as the bottle is simply replaced when empty, maintaining simple manufacturing while increasing total liquid capacity.

AI summary
An electronic cigarette assembly with a replaceable atomizing core includes a main body (200), an atomizing core (300), and a liquid bottle (100). The atomizing core is internally equipped with a first liquid storage cavity (362). First liquid inlet holes (321) are defined in the atomizing core. A second liquid storage cavity (190) is provided inside the liquid bottle. First liquid outlet holes (131) are defined in the liquid bottle. The liquid bottle is equipped with a covering member (140). The covering member covers the first liquid outlet holes when the liquid bottle is not installed on the atomizing core. When the liquid bottle is installed on the atomizing core, each of the first liquid outlet holes is at least partially not covered by the covering member, so that the first liquid outlet holes are in communication with the first liquid inlet holes.
