Atomizer Liquid Blocking Cover for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refillable electronic cigarettes experience tobacco liquid leakage during filling due to the lack of a fixed coupling between the injector and the device, leading to unsatisfactory user experience.
Innovation Solution
An atomizer design featuring a housing assembly with a liquid chamber, a detachable lid, a movably arranged liquid blocking cover, and an elastic element that isolates the atomizing core from the liquid chamber during filling, preventing leakage by driving the liquid blocking cover to a position that separates the atomizing core from the liquid chamber when the lid is detached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the injector is not fixedly coupled with the electronic cigarette, then the filling operation is simple and flexible, but the tobacco liquid leaks when the electronic cigarette is turned over
Solution Approach 1:
The liquid blocking cover acts as an intermediary component between the injector and the atomizing core. It is driven by the lid to move to a first position that blocks the liquid passage, preventing tobacco liquid leakage during filling operations while maintaining operational flexibility
Solution Approach 2:
The liquid blocking cover is designed to be movable rather than fixed, transitioning between a first position (blocking liquid passage during filling) and a second position (allowing liquid flow during normal operation). This dynamic adjustment resolves the contradiction between filling flexibility and liquid containment reliability
2Ease of operation
If the lid is detachable from the housing assembly, then the liquid chamber can be filled with tobacco liquid, but the atomizing core may be exposed to liquid leakage
Solution Approach 1:
The liquid blocking cover is pre-positioned to block the liquid passage when the lid is detached, preventing tobacco liquid from leaking to the atomizing core before the filling operation is complete. This preliminary blocking action ensures the atomizing core remains protected during the entire filling process
3Reliability
If a liquid blocking mechanism is added to prevent leakage, then the tobacco liquid containment is improved, but the device structure becomes more complex
Solution Approach 1:
The lid serves multiple functions: sealing the liquid chamber, driving the liquid blocking cover to the blocking position, and enabling filling operations. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while improving liquid containment reliability
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
Prevents tobacco liquid leakage during filling by ensuring the atomizing core is isolated from the liquid chamber until the lid is securely connected, enhancing user experience by maintaining the integrity of the tobacco liquid within the device.
Implementation Method 1
The elastic element elastically abuts against the liquid blocking cover

AI summary
An atomizer includes (100) a housing assembly (101), an atomizing core (103), a lid (104), a liquid blocking cover (106), and an elastic element (107). The housing assembly defines a liquid chamber (102). The atomizing core is configured for atomizing the tobacco liquid. The lid is configured for sealing the liquid chamber, and is detachable from the housing assembly. The liquid blocking cover is movably arranged in the housing assembly. The elastic element elastically abuts against the liquid blocking cover. When the lid is connected with the liquid blocking cover, the lid is capable of driving the liquid blocking cover to move to a first position where the tobacco liquid in the liquid chamber can flow to the atomizing core. When the lid is detached from the housing assembly, the liquid blocking cover is driven by the elastic element to a second position where the atomizing core is isolated from the liquid chamber.
