Description

Atomizer structure and aerosol generating device

Technical Field

The invention belongs to the field of aerosol, and particularly relates to an efficient atomizer structure and an aerosol generating device.

Background

The electronic cigarette is an electronic product simulating a cigarette, and has the same appearance, smoke, taste and sensation as the cigarette. It is a product which is absorbed by users after nicotine and the like are changed into steam by means of atomization and the like; wherein the atomization is the process that the tobacco tar in the electronic cigarette permeates into the oil absorption cotton and the heating component and is heated.

The cotton winding of oil absorption is on the heating tube basically in the portion that generates heat of current atomizer, and the cotton back of acquireing the tobacco tar from the oil storehouse of oil absorption is heated by the heating tube comprehensively again, and the tobacco tar atomizing volatilizees this moment, is taken away by the air current that flows through. The existing atomizer is always communicated with the oil storage cavity, and if the existing atomizer is not used for a long time, the atomizer can overflow the tobacco tar due to absorption of too much tobacco tar, so that oil leakage is caused; if the heating pipe is excessively used, the heating pipe continuously heats the oil absorption cotton to cause core pasting.
