## Abstract

A vaporizer heating assembly includes an airflow chamber having a proximal end, a distal end opposite the proximal end, and a glass body connecting the proximal end to the distal end. A heating chamber is located within the airflow chamber and includes an elongated glass body and a heating element located within the elongated glass body of the heating chamber. A fan is in fluid communication with the proximal end of the airflow chamber and an attachment adapter is mechanically coupled to the distal end of the airflow chamber in a sealing arrangement, where the attachment adapter forms an attachment port for a vapor receiving element.
