摘要
A toy gun (10) produces a series of travelling smoke rings (12). It has a smoke chamber (14) fed with smoke from a battery (24)-powered electrical resistance generator rear of the smoke chamber (14). A reciprocating actuator (68) movable in response to a trigger (22) strikes the diaphragm (74) to eject a smoke ring (12) through an orifice (14d) in the opposite wall (14a) of the smoke chamber (14). The smoke generator (30) includes a supply tank (32) of a suitable liquid (34) an a source (36) of variable pressure to drive the liquid (34) through a narrow annular clearance (43) to the heater (38) where it is rapidly vaporized. The generator (30) includes a pair of concentric tubes (40, 42) that define the annular clearance (43) and an electrical resistance heating element (38) mounted on one of them at a point spaced from the supply tank.
