Description

Atomization device

Technical Field

The invention relates to the technical field of atomization, in particular to an atomization device.

Background

As the aerosol is a colloidal dispersion system formed by dispersing small solid or liquid particles in a gas medium, and the aerosol can be absorbed by a human body through a respiratory system, the atomization device which can generate the aerosol by heating substances such as medical drugs or tobacco shreds and the like is applied to different fields such as medical treatment, tobacco substitute products and the like, so that the aerosol which can be inhaled is delivered to users.

Taking a baking type atomizing device as an example of a cigarette substitute product, the existing atomizing device has two heating modes, namely a conduction heating mode and a hot air heating mode, so as to bake and heat materials (such as tobacco shreds).

The conduction heating mode heats the material in the heating container by the heat radiation principle, the optimal heat radiation radius is within 3-5mm, and the heat radiation efficiency is greatly reduced beyond the range, so that the material positioned in the center of the heating container can not be completely heated. If the temperature of the heating container is simply increased in order to increase the heat radiation radius, the material near the inner wall of the heating container is burnt by the excessive temperature in the case where the material located at the center has not reached the desired temperature. Therefore, the heating mode of conduction heating has a certain limitation, limiting the capacity of the heating vessel.

The hot air heating mode mainly utilizes air preheating heating to form hot air to heat materials in the heating container in an impact mode, and therefore the materials in the center of the heating container cannot be heated thoroughly. However, the air is preheated for a sufficient preheating time, and the conventional preheating time generally exceeds 60 seconds, so that the heating time is prolonged. Moreover, because the air heating is to heat the material by hot air impact along one direction, and no radiation heating is carried out, the material can be effectively heated only at the place where the hot air passes through, but the radiation cannot reach other places where no air passes through, so that the material at the edge cannot be effectively heated.

Therefore, the heating mode of the existing atomization device cannot simultaneously have the advantages of high heating speed and large heating range, so that the atomization effect of the atomization device is influenced, and the use experience of a user is reduced.
