Atomization Assembly Venting Structure to Block Bubble-Induced Dry Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid feeding difficulty in the atomizing medium of a liquid storage cavity is caused by air bubbles forming in the atomization assembly, which block the liquid feeding opening and lead to dry heating.
Innovation Solution
An atomization assembly with a blocking member positioned to obstruct air bubbles from flowing from a vent channel to the liquid feeding opening, ensuring smooth liquid feeding by preventing bubbles from reaching the opening.

1Reliability
If a vent channel is arranged to enable the liquid storage cavity to be in communication with the outside atmosphere, then pressure balance is achieved and liquid leakage is prevented, but air bubbles enter the liquid storage cavity through the vent channel and block the liquid feeding opening, causing liquid feeding difficulty
Solution Approach 1:
The vent channel is segmented into two separate channels: a first vent channel for air bubbles and a second vent channel for liquid communication. This segmentation allows air bubbles to be vented separately from the liquid feeding path, preventing bubble blockage while maintaining pressure balance. The liquid storage cavity has dedicated pathways for different functions (air venting and liquid feeding) that do not interfere with each other.
Solution Approach 2:
The harmful function of the vent channel (allowing air bubbles to enter and block the liquid feeding opening) is extracted and separated from the useful function (maintaining pressure balance). By creating a dedicated air bubble venting path that is spatially separated from the liquid feeding opening, the harmful effect is removed while the beneficial pressure balancing function is preserved.
2Productivity
If air bubbles are allowed to escape from the liquid storage cavity, then continuous liquid feeding is maintained, but the bubbles may obstruct the liquid feeding opening during the escape process
Solution Approach 1:
The venting function is segmented into separate channels: the first vent channel is dedicated to air bubble escape, while the liquid feeding opening remains separate. This ensures that bubbles can escape continuously without obstructing the liquid feeding path, maintaining both continuous liquid feeding and preventing bubble obstruction simultaneously.
Solution Approach 2:
The first vent channel acts as an intermediary pathway that facilitates bubble escape without allowing bubbles to directly interact with the liquid feeding opening. This intermediate channel mediates between the need to remove bubbles and the need to maintain clear liquid feeding, allowing bubbles to be transported away from the feeding opening through a separate route.

AI summary
An atomization assembly and an electronic atomization device are provided. The atomization assembly includes a liquid storage cavity is configured to store an atomizing medium. A liquid opening is communicated with a bottom portion of the liquid storage cavity. At least one vent channel includes a first port and a second port. The first port is in communication with the liquid storage cavity, and the second port is in communication with an outside atmosphere. A blocking member is arranged in the liquid storage cavity and located on a side of the second port facing the liquid feeding opening. The blocking member minimizing air bubbles flowing from the second port to the liquid opening.
