Rotatable Mouthpiece Airflow Layout for Sensor-Protected Atomizers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices for electronic cigarettes face issues with e-liquid reflux contaminating sensors and interference between air passages, affecting user experience and sensitivity.
Innovation Solution
The atomizing device features independent main and branch air passages and sensors, with a rotatable mouthpiece allowing selective communication between them, and includes multiple cartridge chambers and air inlet channels to prevent contamination and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sensor is placed on the main air passage through the cartridge chamber, then the device structure is simplified, but the e-liquid reflux contaminates the sensor
Solution Approach 1:
The air passage is divided into two independent segments: the main air passage for vapor transport and the branch air passage for sensor communication. This segmentation isolates the sensor from the e-liquid reflux path while maintaining structural efficiency.
Solution Approach 2:
The branch air passage acts as an intermediary channel, allowing the sensor to communicate with the inhalation port without being directly exposed to the e-liquid in the cartridge chamber, thus preventing contamination.
2Reliability
If the sensor is placed away from the inhalation port, then the sensor is protected from e-liquid reflux, but the path length from mouthpiece to sensor increases
Solution Approach 1:
The branch air passage extends in a direction perpendicular to the main air passage, allowing the sensor to be positioned closer to the inhalation port in a different spatial dimension while maintaining protection from e-liquid reflux.
3Device complexity
If only one air passage is provided, then the device structure is simplified, but air passage blockage affects all cartridges
Solution Approach 1:
The air passage system is segmented into multiple independent main air passages, each serving a specific cartridge chamber. This allows one cartridge to be blocked or replaced without affecting other cartridges, enhancing system versatility and reliability.
Solution Approach 2:
The system allows dynamic configuration of which air passage is active by controlling the mouthpiece rotation, enabling adaptation between different cartridge configurations without structural changes.
4Device complexity
If the mouthpiece is fixed, then the structure is simplified, but the user cannot selectively communicate with different air passages
Solution Approach 1:
The mouthpiece is designed with rotational capability, transforming it from a fixed structure to a dynamic one that can selectively align with different air passages, providing user control over which cartridge is active.
Solution Approach 2:
The mouthpiece can be rotated in advance to position the inhalation port aligned with the desired air passage before use, allowing users to pre-select which cartridge will be activated.

AI summary
An atomizing device (100) has a length direction (X) and includes an atomizing body (10) and a mouthpiece (30). The atomizing body (10) includes a first end (10a) and a second end (10b) spaced apart in the length direction (X), and further includes cartridge chambers (21), main air passages (23), branch air passages (25), and sensors (27). Each main air passage (23) and each branch air passage (25) are independent of each other. Each main air passage (23) and each branch air passage (25) extend through the first end (10a) respectively. Each cartridge chamber (21) communicates with one main air passage (23), and each sensor (27) communicates with one branch air passage (25). The mouthpiece (30) is rotatably connected to the first end (10a) and includes an inhalation port (31) selectively and simultaneously communicating with one main air passage (23) and one branch air passage (25).
