Description

The present invention relates to the field of atomization technology, and more particularly to atomizers.

Aerosols are colloidal dispersions formed when small particles of solid or liquid are dispersed and suspended in a gaseous medium.Aerosols are absorbed into the human body through the respiratory system, thus providing users with a new alternative means of absorption. . Atomizer means a device that forms an aerosol from a stored atomizable medium by methods such as heating or ultrasound.

Non-combustion heated aerosol-generating substrates use a special heat source to heat the substrate (heating temperature is below 500℃ or lower), and various substances in the atomized substrate are vaporized when heated. This is a new substrate that generates aerosol to meet the needs of smokers. Non-combustion heated aerosol-generating substrates do not produce open flames or soot during the inhalation process, making them more environmentally friendly and providing a better user experience, while also eliminating harmful substances due to high-temperature decomposition during combustion of traditional substrates. occurrence, thereby reducing damage to the user's body.

Conventional non-combustion heated atomization devices for atomizing aerosol-generating substrates have a heating cavity, and after inserting the atomizing medium into the heating cavity, an external airflow flows from the bottom of the atomizing substrate into the aerosol-generating substrate. The airflow mixes with the active substance, such as scent, generated by heating the interior of the aerosol-generating substrate, which is then inhaled by the user. However, due to the airflow introduced into the bottom of the aerosol-generating substrate, the temperature of the aerosol-generating substrate decreases, and the substance in the aerosol-generating substrate is not baked sufficiently and the active substances in it are not completely released, resulting in atomization. The amount of active substance contained in the aerosol output from the device is smaller, reducing the usability of the atomizing device.

In view of this, for the problem that the aerosol-generating substrate is not baked enough, we recommend an atomizer that bakes the aerosol-generating substrate and the content of active substances in the aerosol formed can achieve a higher technical effect. need to be provided.
