Electronic Cigarette Liquid Bottle With Controlled Refill Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable electronic cigarettes have a small tobacco liquid capacity and cannot be refilled, leading to a short usage time and excessive liquid inhalation due to continuous communication between the liquid bottle and atomizing core.
Innovation Solution
An electronic cigarette assembly with a liquid bottle featuring a controllable liquid injection control component that blocks and communicates the liquid outlet channel under external force, allowing controlled addition of tobacco liquid to the cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an independent liquid bottle is installed on the electronic cigarette to increase tobacco liquid capacity, then the usage time is extended, but the liquid outlet channel remains continuously communicated with the atomizing core causing excessive tobacco liquid to enter the cartridge
Solution Approach 1:
The liquid outlet channel is designed with a movable cover member that can switch between blocked and open states. The cover member is driven by an operating member that responds to user operations, allowing the system to dynamically control liquid flow. This resolves the contradiction by enabling the liquid bottle to be installed for extended usage while preventing excessive liquid from entering the cartridge through controlled communication of the liquid outlet channel.
2Productivity
If the liquid outlet channel is continuously communicated with the atomizing core to allow free liquid flow, then the atomizing core can be continuously supplied with tobacco liquid, but users may inhale excessive tobacco liquid along the aerosol outlet channel
Solution Approach 1:
The cover member acts as an intermediary between the liquid outlet channel and the atomizing core. It controls the communication between these two components, allowing liquid supply when needed while preventing excessive liquid from reaching the aerosol outlet channel. This mediator mechanism resolves the contradiction by enabling controlled liquid flow that maintains supply efficiency while preventing harmful excessive inhalation.
3Object-affected harmful factors
If a liquid injection control component is added to block and control the liquid outlet channel, then excessive tobacco liquid inhalation is prevented, but the device structure becomes more complex
Solution Approach 1:
The cover member is designed as a flexible component that can be moved to block or open the liquid outlet channel. This flexible membrane-like structure provides effective liquid flow control without requiring complex mechanical assemblies. The operating member simply needs to push or pull the cover member, creating a simple control mechanism that prevents excessive liquid inhalation while minimizing structural complexity.
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 usage time and reduces excessive liquid consumption by enabling controlled tobacco liquid injection, improving user experience and reducing costs through replaceable cartridges.
Implementation Method 1
The covering member is restored to an initial state by the first elastic member when the operating member is released
Implementation Method 2
the second elastic member pushes the operating member back to an initial position when the operating member is released
Implementation Method 3
liquid absorbing cotton for adsorbing tobacco liquid is provided in the first liquid cavity

AI summary
An electronic cigarette assembly with controllable tobacco liquid injection includes a main body of electronic cigarette and a liquid bottle externally installed on the main body of electronic cigarette. The main body of electronic cigarette includes a cartridge. The cartridge is equipped with a first liquid cavity and a liquid inlet hole communicated with the first liquid cavity. The liquid bottle is provided with a second liquid cavity and a liquid outlet channel communicated with the second liquid cavity. A liquid injection control component is provided on the liquid bottle. When the liquid bottle is installed on the main body of electronic cigarette, the liquid outlet channel is in communication with the liquid inlet hole. The liquid injection control component blocks the liquid outlet channel in an initial state, and communicates the liquid outlet channel under external force to add tobacco liquid to the cartridge, thereby increasing the usage time.
