ABSTRACT:
A pump cleaning unit for a heater fixture of a smoking device includes a base member. The base member includes a cup having an open end and a closed end, and a pedestal including a top part disposed in the cup proximate the open end of the cup and a leg connecting the top part to the closed end of the cup. A peripheral edge of the top part and an interior wall of the cup define a circumferential gap. The unit further includes a cylinder having a lower chamber and an upper chamber separated by a wall, a port extending through the wall. The cylinder has a cylinder wall proximate the lower chamber that fits in the circumferential gap and permits axial movement of the cylinder relative to the cup. A holder is provided for holding the heater fixture in the upper chamber over the port such that a central opening of the heater fixture is in flow communication with the port.
