Atomizer Vent Tube for Liquid Feeding Pressure Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices experience obstructed liquid feeding due to negative pressure formation in the liquid storage cavity, which prevents smooth flow of the aerosol-generation substrate to the atomization core.
Innovation Solution
Incorporating a vent tube between the sleeve and the atomization core to create a vent channel that communicates with the liquid inlet hole and the outside, maintaining air pressure balance and ensuring smooth liquid feeding by allowing external air to flow into the liquid storage cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cotton core atomization core is plugged in a sleeve with continuous liquid flow through a liquid inlet hole, then liquid can be supplied to the atomization core, but negative pressure forms in the liquid storage cavity causing obstructed liquid feeding
Solution Approach 1:
The patent introduces a vent tube as an intermediary component between the liquid storage cavity and the external environment. This vent tube provides a dedicated air intake path that mediates the pressure balance, allowing external air to enter the liquid storage cavity and prevent negative pressure buildup, thereby ensuring continuous and smooth liquid feeding to the atomization core
2Ease of operation
If the atomization core is assembled in the sleeve with a liquid inlet hole, then liquid can flow from the liquid storage cavity to the atomization core, but air cannot enter the liquid storage cavity to maintain pressure balance
Solution Approach 1:
The patent segments the functional pathways by separating the liquid flow path (through the liquid inlet hole and atomization core) from the air intake path (through the vent tube). This segmentation allows liquid to be supplied to the atomization core while simultaneously enabling external air to enter the liquid storage cavity through the dedicated vent tube channel, maintaining pressure balance without interfering with liquid flow
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The vent channel prevents negative pressure buildup, allowing for uninterrupted and balanced air pressure, thereby ensuring continuous and unobstructed liquid feeding to the atomization core.
Implementation Method 1
the vent channel is configured to be in communication with the liquid inlet hole and an outside... external air can flow to the liquid inlet hole and the liquid storage cavity through the vent channel, so as to prevent formation of a negative pressure in the liquid storage cavity, and maintain the air pressure balance between the liquid storage cavity 20 and the outside atmospheric pressure
