Atomizing Device Bending Section Prevents Liquid Leakage

Solution Overview

Problem

Conventional atomizing devices face issues with liquid leakage into the puff sensor, leading to device failure and reduced service life due to fluid communication between the air inlet and the puff sensor.

Innovation Solution

The atomizing device incorporates an airflow passage with a bending section that prevents liquid from reaching the puff sensor, featuring sequentially connected segments at angles to redirect airflow and include a suction nozzle and a puff sensor arrangement that minimizes liquid flow to the sensor.

1Reliability

If the puff sensor is fluidly communicated with the air inlet to sense user's drawing operation, then the sensing function is improved, but liquid leakage causes the puff sensor to fail and the device is scrapped

Engineering Contradiction:

Improvepuff sensor reliabilityVSAvoidliquid leakage to puff sensor

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The airflow passage is divided into multiple segments (first airflow passage, second airflow passage, third airflow passage) that are sequentially connected at angles. This segmentation creates a multi-bend path that physically blocks liquid from reaching the puff sensor while maintaining airflow communication, thus preventing liquid leakage damage to the sensor.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The airflow passage extends in multiple spatial dimensions with sequential segments arranged at angles to each other. This multi-dimensional routing creates a complex path that allows air to reach the sensor while preventing liquid, which would follow a more direct gravitational path, from reaching the sensor.

AI summary

The invention relates to an atomizing device, including an atomizer, a puff sensor and an airflow passage. A transfer passage is defined in the atomizer, and two end portions of the airflow passage are respectively fluidly communicated with the transfer passage and the puff sensor. The airflow passage comprises a bending section, which is configured to prevent liquid in the atomizer from flowing to the puff sensor. With the bending section, liquid is difficult to reach the puff sensor even if it flows into the main body, therefore the safety and the service life of the atomizing device are improved.
