Magnetic Sealing Plug for Electronic Cigarette Atomizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly mode of atomizing devices in electronic cigarettes, which relies on a latching fit for connecting the atomizer to the power supply, often results in poor contact due to wear over time, shortening the device's service life.
Innovation Solution
The atomizing device incorporates a magnetic attraction mechanism using a sealing plug with a magnetic attraction surface, which securely connects the atomizing device to the power supply device, eliminating the need for a conventional latching structure and reducing wear-related failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a latching fit assembly mode is used to connect the atomizing device to the power supply device, then the structure is simple and easy to manufacture, but the contact between components deteriorates over time due to wear, shortening service life
Solution Approach 1:
The patent replaces the mechanical latching fit connection with a magnetic field-based connection. The magnetic connection member in the power supply device interacts with the magnetic attraction surface on the sealing plug through magnetic force, eliminating mechanical contact and wear between the atomizing device and power supply device, thereby maintaining stable connection over time while preserving assembly simplicity
2Device complexity
If a latching fit structure is used for connecting components, then the device complexity is low, but the service life is shortened due to wear of engaged snaps
Solution Approach 1:
The patent substitutes the mechanical latching structure with a magnetic field-based connection system. The magnetic connection member and magnetic attraction surface create a non-contact magnetic field interaction that maintains connection stability without wear, extending service life while keeping the connection structure simple and easy to implement
3Ease of operation
If the sealing plug is made detachable for liquid injection, then the ease of operation is improved, but the connection reliability between atomizing device and power supply may be compromised
Solution Approach 1:
The sealing plug is designed to perform multiple functions: it seals the liquid injection channel to prevent leakage, provides a magnetic attraction surface for magnetic connection to the power supply device, and allows detachable removal for liquid injection. This multi-functionality ensures both operational convenience for liquid refilling and reliable magnetic connection stability
Solution Approach 2:
The detachable sealing plug incorporates a magnetic connection mechanism that replaces traditional mechanical locking structures. The magnetic field-based connection maintains reliable attachment between the detachable sealing plug and power supply device, ensuring connection stability is not compromised by the detachable design needed for liquid injection
