Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes suffer from corrosion and malfunction due to moisture from vaporized e-liquid contacting electronic components in the rod-shaped battery assembly, leading to short circuits or open circuits.
Innovation Solution
A rod-shaped battery assembly with a moisture isolation means, comprising a hollow battery tube, a light cap, and a negative pole connecting piece, which includes an electrical insulation ring and a positive pole connecting piece, and further features a moisture isolation mechanism to confine vapor moisture, using water-absorbable breathable materials or one-way valves to prevent contact with air sensors and circuit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vapor flows back to the battery assembly after pausing smoking, then the vapor can be contained and potentially reused, but moisture in the vapor contacts and corrodes the air sensor and circuit board
Solution Approach 1:
The battery assembly is divided into distinct functional zones: a first cavity containing the air sensor and circuit board, and a second cavity containing the battery. The partition wall separates these cavities, preventing moisture from the vapor flow path from reaching the electronic components in the first cavity.
Solution Approach 2:
A hydrophobic coating is applied to the partition wall and/or vapor flow path surfaces. This coating acts as an intermediary layer that repels moisture while allowing vapor to pass through, preventing direct contact between moisture and the air sensor/circuit board.
2Reliability
If a moisture isolation means is added to prevent moisture contact, then component reliability improves, but device complexity increases
Solution Approach 1:
The battery assembly is divided into distinct functional zones: a first cavity containing the air sensor and circuit board, and a second cavity containing the battery. The partition wall separates these cavities, preventing moisture from the vapor flow path from reaching the electronic components in the first cavity.
Solution Approach 2:
A hydrophobic coating is applied to the partition wall and/or vapor flow path surfaces. This thin film provides moisture isolation while maintaining structural integrity and allowing vapor permeation, adding minimal complexity to the overall assembly.

AI summary
The present invention discloses a rod-shaped battery assembly (001) and an electronic cigarette having the rod-shaped battery assembly (001). The rod-shaped battery assembly (001) is configured for connecting a rod-shaped vaporizer assembly (002) of an electronic cigarette and providing the rod-shaped vaporizer assembly (002) with power. The rod-shaped battery assembly (001) comprises a hollow battery tube (1), a light cap (2) sheathed in one end of the battery tube (1), and a negative pole connecting piece (3) sheathed in the other end of the battery tube (1). The battery tube (1) sheathes an air sensor (4), a circuit board (6), and a battery (7); the negative pole connecting piece (3) sheathes an electrical insulation ring (8) and a positive pole connecting piece (9). The battery tube (1) further sheathes a moisture isolation means (10). The advantageous effects of the present invention are that when the vapor produced in the rod-shaped vaporizer assembly (001) flows back through the moisture isolation means (10) during smoking, the moisture contained in the vapor will be confined to one side of the moisture isolation means (10) to prevent the contact between the moisture and the air sensor (4) and the circuit board (6). This further prevents the moisture causing corrosion of the air sensor (4) and the circuit board (6) or causing short circuit or open circuit, which therefore gives rise to malfunction of the electronic cigarette.
