Abstract: A smoke diffusing device for distributing aromatic smoke from burning material, such as tobacco, incense, or the like, throughout a room comprises a housing having a receptacle thereon for holding burning material, a fan chamber within the housing into which the smoke is drawn from the receptacle through an inlet passage and from which it is forcibly expelled to atmosphere through an outlet passage by a small switch-operated battery-powered motor-driven fan located in the fan chamber. The fan motor, battery, switch, and necessary electric wiring are removably mounted and detachably interconnected in a main chamber in the housing. The main chamber, fan chamber, inlet passage and receptacle are defined by a cylindrical bore extending inwardly of the housing, and one end of the bore is closed by a removable end cap on which the switch is mounted.
