Leak-Proof E-Liquid Inlet Structure for Vaporizer Cartridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes suffer from E-liquid leakage due to vibrations during transportation or storage, leading to waste and contamination, and negatively impacting user experience.
Innovation Solution
A leak-proof structure is introduced, allowing the E-liquid injection hole to open during use and close during non-use, utilizing a mechanically co-movable design with the cartridge mouthpiece to prevent E-liquid flow when not in use, ensuring the E-liquid remains sealed and protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the E-liquid inlet remains open to allow continuous E-liquid flow to the atomizing core, then the atomization function is maintained, but E-liquid leakage occurs due to vibration during transport or storage
Solution Approach 1:
The patent implements a dynamic leak-proof structure that can switch between open and closed states. The movable blocking member is positioned to block the E-liquid inlet during transport, but can be moved away to allow E-liquid flow during use. This dynamic adjustment resolves the contradiction by adapting the system state to different operational requirements.
Solution Approach 2:
The patent introduces a movable blocking member as an intermediary element between the E-liquid storage tank and the atomizing core. This blocking member acts as a mediator that can selectively open or close the E-liquid flow path, preventing direct leakage while allowing controlled flow when needed.
2Object-generated harmful factors
If a leak-proof structure is added to prevent E-liquid leakage, then E-liquid containment is improved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the leak-proof structure with the existing cartridge and mouthpiece assembly. The movable blocking member is integrated into the cartridge structure, and its movement is coupled with the mouthpiece position. This merging approach prevents E-liquid leakage while avoiding significant increases in overall device complexity.
Solution Approach 2:
The movable blocking member serves multiple functions: it acts as a leak prevention barrier during transport, can be moved to allow E-liquid flow during use, and its movement is mechanically coupled to the mouthpiece position indicator. This multi-functionality reduces the need for separate components, thereby limiting complexity increase.
3Object-generated harmful factors
If the E-liquid inlet is closed to prevent leakage, then E-liquid containment is improved, but the ease of operation is reduced
Solution Approach 1:
The patent implements a self-service mechanism where the act of inserting or removing the cartridge from the main body automatically moves the blocking member to the appropriate position. When the cartridge is inserted, the blocking member is positioned to allow E-liquid flow; when removed, it automatically blocks the inlet. This eliminates the need for separate user actions to open or close the E-liquid inlet.
Solution Approach 2:
The patent performs preliminary action by pre-positioning the movable blocking member based on the cartridge insertion state. The system anticipates the user's need by automatically adjusting the E-liquid flow path closure before the user actually uses the device or stores it, making the operation seamless and convenient.

AI summary
An atomization generating device includes a cartridge (1) including an E-liquid storage tank (19), a bottom base (132), and a vapor channel. The vapor channel (16) is connected with an external environment through a cartridge mouthpiece (17). An atomizing core (15) is disposed at the bottom base and at a lower end of the vapor channel. The atomizing core includes an E-liquid inlet (151). The atomization generating device also includes a main body (3) including a receiving chamber (31). The cartridge (2) includes a leak-proof structure configured to be mechanically co-movable with the cartridge mouthpiece to open and close the E-liquid inlet. The leak-proof structure is configured with a first position and a second position. When the leak-proof structure is at the first position, the E-liquid inlet is closed to block an E-liquid from entering the atomizing core. When the leak-proof structure is at the second position, the E-liquid inlet is open to guide the E-liquid into the atomizing core.
