Aerosol generating device, charging base, and electric system

An aerosol generating device, which is configured for heating a smokable material so as to volatilize at least one ingredient of the smokable material, comprising:

• a first part having a length in a length direction, and comprising a chamber configured for receiving at least part of a smokable material, and a heating element arranged inside the chamber and extending in the length direction of the first part;
• the first part also comprising a gap extending in the length direction of the first part, through which one can reach the chamber to clean the heating element;
• wherein a cross section of the first part perpendicular to the length direction and passing through the gap has a width in a width direction and a thickness in a thickness direction, wherein the width is longer than the thickness, wherein along the width direction, a first distance between the heating element and the gap is greater than a second distance between the heating element and a chamber wall that is opposite to the gap, wherein the cross section and the first distance provide that the heating element is asymmetrically arranged within the chamber, wherein the heating element has a distance greater than 10 mm to the gap along the width direction, wherein
• in the direction of the cross section of the first part, connecting lines from the center of the heating element to two ends of the gap forming an included angle less than 90 degrees;
• and
• a second part removably connected to the first part through a connection structure, wherein the second part is arranged to close or open the gap.
