What is an integrated oil storage cotton and oil guide cotton?

In the hot atomizer industry, as atomizers, batteries only provide power for endurance, while atomization oil relies on Oil storage cotton for endurance. Atomization requires atomization heating components (heating wire, heating bracket, fiberglass tube, oil guide cotton, etc.) to prevent oil leakage or condensate leakage, so it is necessary to add oil absorption cotton components.
Previously, the solutions used were all two or more sections of Oil storage cotton spliced together. However, it is understood that currently, disposable small Y atomizers are mostly using integrated Oil storage cotton. Therefore, those who have a basic understanding of this industry have a shadow in their minds. Let's take a look at its "facial features".
