Electronic vaporization device and vaporizer thereof

A vaporizer, comprising:

• a housing;
• and
• a vaporization assembly arranged in the housing, a vaporization cavity configured to accommodate the vaporization assembly being arranged in the housing, and an airflow channel being arranged in the housing at one side of the vaporization cavity and in communication with the vaporization cavity;
• an air inlet in communication with the vaporization cavity;
• and
• an airflow guide structure arranged in the vaporization cavity and configured to guide an airflow at the air inlet,
• wherein the airflow guide structure is arranged close to the airflow channel,
• wherein the airflow guide structure is arranged between the vaporization assembly and the air inlet,
• wherein a spacing is reserved between the airflow guide structure and the vaporization assembly,
• wherein the spacing forms a communication channel that communicates the vaporization cavity with the airflow channel,
• wherein the vaporization cavity further comprises a closed region arranged opposite the airflow channel,
• wherein the airflow guide comprises an airflow guide surface obliquely angled relative to an air inlet end surface of the air inlet, and
• wherein the airflow guide surface is arranged towards the closed region so as to guide a part of the airflow to the closed region of the vaporization cavity, and squeeze, accelerate, and guide the airflow outputted to the airflow channel from the vaporization cavity.
