Description

Atomizer and electronic atomization device

Technical Field

The utility model relates to the technical field of electronic cigarettes, in particular to an atomizer and an electronic atomization device.

Background

At present, the air passage design of the electronic cigarette atomizer is basically that air flow directly blows or closely blows through the atomizing surface of the atomizing core. Because the airflow velocity in the atomizer is higher during suction, the flow velocity can reach 10-20 m/s, so that forced flow heat exchange of air to the atomizing core is very strong, a large amount of heat is lost to the atomizing core and the heating body, and the heat utilization efficiency of the atomizer is greatly reduced.

In an atomizer disclosed in patent publication No. CN215075497U, the tangential angle between the tangential line of the air inlet channel at the joint of the communicating atomizing chambers and the atomizing surface is an acute angle, so that the air flow entering the atomizing chambers from the air inlet channel is prevented from deflecting in a larger direction, and the air flow is reduced to form vortex in the atomizing chambers. According to the technical proposal, although the loss of air flow and retention and residence time in aerosol are reduced, the condensate generated in an atomization cavity is reduced; but this technical scheme also forms the vortex and has reduced the cooling heat dissipation of air current to atomizing core to a certain extent through reducing the air current in atomizing intracavity simultaneously, and then has alleviateed the heat loss that the atomizing core caused because the air current directly blows the atomizing face.

Therefore, in order to further alleviate the cooling heat loss caused when the air flow blows across the atomizing surface of the atomizing core, the heat utilization efficiency of the atomizing core is improved, and a technical scheme with high heat utilization rate of the atomizing core is necessarily designed.
