Abstract
Abstract A smoke drawing device comprises a base of floor lamp type configuration having a drawing fan therein. A tabular member of floor lamp type configuration is supported substantially vertically by the base over the fan. The tubular member is bent at substantially right angles to itself at its free end away from the base. A lampshade type unit is mounted on the tubular member at the free end thereof and opens into the tubular member in a manner whereby smoke in the area of the lampshade type unit is drawn by the fan through the tubular member and out through the base.
