The present invention provides a smoking machine for an electronic cigarette, relating to the technical field of electronic cigarettes. The smoking machine for an electronic cigarette comprises: a housing; a rotary disc installed on a side surface of the housing, a central axis of the rotary disc is parallel to a horizontal plane, and the rotary disc rotates relative to the housing with the central axis of the rotary disc as a center, a disc-body smoking through hole is provided on an end face of the rotary disc, a housing sealing member is disposed on a side surface of the housing, a sealing ventilation hole penetrating into the housing in a horizontal direction is provided in the housing sealing member, and an end face of the housing sealing member is in contact with the end face of the rotary disc; and a main control circuit board electrically connected to the rotary disc. The rotary disc of the present invention is perpendicular to a horizontal plane, and the electronic cigarette circumferentially rotates along with the rotary disc in a smoking experiment process, so that tobacco tar in a cigarette cartridge flows and fully immerses the oil guiding cotton, thus ensuring sufficient and steady supply of the tobacco tar to an atomizer, and guaranteeing atomization efficiency, atomization amount, and the stability and accuracy of experiment data.
