Power Supply Vent Groove for Flat Electronic Atomizer Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic atomization devices face challenges in miniaturization and flat design due to the large space occupied by the start airway on the power supply assembly, which is necessary for the airflow sensor.
Innovation Solution
The power supply assembly incorporates a magnetic member and an airflow sensor in air communication with a vent groove, eliminating the need for an additional start airway by using a mounting hole with a vent groove and a communication member with a vent hole to detect airflow, allowing for a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate start airway is provided for the airflow sensor on the power supply assembly, then the airflow detection function is reliable, but the device occupies large space and is not conducive to miniaturization
Solution Approach 1:
The patent combines the start airway function with the magnetic member mounting hole. The vent groove is formed on the inner wall of the first mounting hole, allowing the airflow sensor to detect airflow through the same structural component that mounts the magnetic member. This merging of functions eliminates the need for a separate start airway structure, reducing device volume while maintaining reliable airflow detection.
Solution Approach 2:
The first mounting hole serves multiple functions: it mounts the magnetic member for magnetic interaction with the atomization assembly, and simultaneously provides the vent groove for airflow detection. This multi-functional design allows a single structural element to perform both magnetic coupling and airflow sensing tasks, thereby reducing the overall device volume and supporting miniaturization goals.
2Volume of moving object
If the power supply assembly structure is simplified to reduce space, then miniaturization is achieved, but the airflow communication path may be compromised
Solution Approach 1:
The vent groove is integrated into the inner wall of the first mounting hole, creating a compact airflow passage that maintains reliable communication between the airflow sensor and the atomization assembly. This integrated design ensures that even in a miniaturized configuration, the airflow path remains functional and reliable for detecting user inhalation.

AI summary
The present invention relates to an electronic atomization device and a power supply assembly thereof. The power supply assembly is provided with a first mounting hole (12) configured to mount a magnetic member (20), where an inner wall of the first mounting hole (12) is provided with a vent groove (121); and the power supply assembly includes an airflow sensor, and the airflow sensor is in air communication with the vent groove. The inner wall of the first mounting hole configured to mount the magnetic member is configured to provide the vent groove, so that the airflow sensor is in air communication with an atomization assembly. In this way, a start airway does not need to be additionally provided for the airflow sensor on the power supply assembly, which saves space on the power supply assembly and is conducive to the miniaturization and flat design of a product.
