Atomization Assembly Venting to Prevent Bubble-Fed Dry Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid feeding difficulty in the atomizing medium of a liquid storage cavity is caused by bubbles forming in the atomization assembly due to air entering through a vent channel, which can block the liquid feeding opening and lead to dry heating.
Innovation Solution
An atomization assembly with a blocking member positioned to prevent bubbles from flowing from a vent channel port to the liquid feeding opening, ensuring smooth liquid feeding by blocking the bubbles and allowing them to float up instead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vent channel is arranged to enable the liquid storage cavity to be in communication with the outside atmosphere, then pressure imbalance and liquid leakage are prevented, but air entering through the vent channel forms bubbles that block the liquid feeding opening causing liquid feeding difficulty
Solution Approach 1:
The vent channel is segmented into two separate ports: a first port for air entry and a second port for air exit. This segmentation prevents bubbles formed at the first port from traveling to and blocking the liquid feeding opening, as the exit port is positioned away from the liquid feeding path.
Solution Approach 2:
A blocking member is introduced as an intermediary element between the vent channel and the liquid feeding opening. This blocking member selectively prevents bubbles from reaching the liquid feeding opening while allowing the vent channel to maintain pressure balance functionality.
2Reliability
If the vent channel allows air to enter the liquid storage cavity, then pressure imbalance is avoided, but the liquid feeding opening becomes blocked by bubbles
Solution Approach 1:
The vent channel is divided into separate entry and exit ports positioned at different locations. The first port allows air entry for pressure communication, while the second port is positioned such that bubbles exiting do not block the liquid feeding opening, thereby maintaining both pressure communication and liquid feeding productivity.
Solution Approach 2:
The blocking member serves as a mediator that selectively intercepts bubbles between the vent channel and the liquid feeding opening, allowing pressure communication to occur while preventing bubble-induced blockage of the liquid feeding path.
3Reliability
If bubbles flow from the vent channel to the liquid feeding opening, then pressure equalization occurs, but liquid feeding is blocked and dry heating occurs
Solution Approach 1:
By segmenting the vent channel into separate first and second ports, the system maintains pressure equalization functionality while directing bubbles away from the liquid feeding opening, thereby preventing the harmful effect of dry heating.
Solution Approach 2:
The blocking member acts as an intermediary that prevents bubbles from reaching the liquid feeding opening, thereby eliminating the harmful effect of dry heating while preserving pressure equalization through the vent channel.
