Vaporization Device Integrated Liquid Injection and Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vaporization apparatuses is complicated due to separate components for the mouthpiece and e-liquid storage tank, requiring inconvenient and time-consuming liquid injection processes, with a risk of leakage if not sealed properly.
Innovation Solution
A vaporization device design featuring an upper housing with a liquid injection channel and a main body with a locking and seal mechanism, allowing for two connection states: one for liquid injection and another for secure sealing, facilitating efficient assembly and reducing leakage risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mouthpiece and e-liquid storage tank are assembled as separate components requiring liquid injection, then the device allows for flexible assembly and maintenance, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent combines the mouthpiece assembly and e-liquid storage tank into a single integrated unit with a unified shell. The liquid storage cavity, vaporization cavity, and airflow channels are formed as one piece, eliminating the need for separate assembly steps and liquid injection operations, thereby significantly reducing assembly time and complexity
Solution Approach 2:
The integrated shell structure serves multiple functions simultaneously: it contains the e-liquid, forms the vaporization chamber, provides airflow passages, and acts as the outer protective housing. This multi-functionality eliminates the need for separate components and simplifies the overall assembly process
2Reliability
If liquid injection is performed before mounting the mouthpiece, then the liquid can be properly injected into the storage tank, but the process becomes complicated and the risk of leakage increases
Solution Approach 1:
By merging the mouthpiece and storage tank into a single integrated component, the patent eliminates the liquid injection step entirely. The e-liquid is contained within the integrated shell from manufacturing, and no additional injection or sealing operations are required during assembly, thereby reducing both complexity and leakage risk
3Strength
If the mouthpiece is fixed to the main body with snaps or rivets through press-fit, then the components are securely attached, but the assembly process becomes inconvenient and time-consuming
Solution Approach 1:
The patent integrates the mouthpiece structure directly into the storage tank shell, creating a unified component that requires no separate attachment operations. The integrated design maintains structural strength while eliminating the need for snaps, rivets, or press-fit operations, thereby greatly improving assembly convenience

AI summary
A vaporization device includes: an upper housing having a liquid injection channel and a connection portion; and a main body including a liquid storage tank configured to store liquid, a locking portion, and a seal member. The upper housing is sleeved on the main body and fixedly connects the locking portion to the connection portion. When the locking portion is fixedly connected to the connection portion and is in a first state, the liquid injection channel is in communication with the liquid storage tank. When the locking portion is fixedly connected to the connection portion and is in a second state, the seal member blocks the liquid injection channel.
