Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an atomizer core and an atomizer. Background Art

[0002] Atomization technology refers to heating a substance with an atomizer to release an aerosol so that the human body can inhale it to obtain a certain degree of inhalation satisfaction. The atomization quality of the aerosol at the inhalation port is limited by the heating area of ​​the heater and the convergence of the airway. The larger the heating area, the more thorough the heating, the better the convergence of the airflow, and the better the aerosol agglomeration at the inlet. The same volume of aerosol has a large density and mass, and the inhalation satisfaction is strong. The atomizers in the prior art are mostly rod-shaped, and the heating body is arranged around or inside it. In this way, the atomizer inside the rod blocks the airflow, and the heating surface is limited. For example, the heating body is arranged around the rod-shaped atomizer, and only a thin layer around the rod-shaped atomizer is heated. The heated atomizer is inhaled into the inlet through inhalation, and there is very little atomized aerosol; another heating body is arranged in the center of the rod-shaped atomizer. In this way, only the atomizer contacting the surface of the heating body is atomized, and there is also little aerosol. In these two ways, the airflow does not have the traction of spiral rise, and the effect of a large aerosol cannot be quickly obtained. Utility Model Content
