Patent Images
1. A smoke generator, which comprises:
- (a) a compartment having a gas ingress and a gas egress,(b) smoke generating means comprising an electrical resistance means and smoke generating material means in close contact with said electrical resistance means disposed in said compartment, and an electrical energy source means(c) control means controlling operation of blowing air into said ingress to cause smoke existing in said compartment to exit said compartment through said egress, said control means then actuating said smoke generating means, wherein said control means comprises a normally open switch electrically connected to said electrical energy source and said electrical resistance means, a movable member for closing said switch in response to predetermined movement of said movable member to cause said smoke generating means to generate smoke, said movable member being in the shape of a piston, said smoke generator further including a piston housing containing said movable member and a passage communicating between said piston housing and said compartment ingress to drive air from said piston housing, when said movable member is moved to close said switch, through said passage, to said ingress, to force smoke existing in said compartment out of said egress.

Abstract
The disclosure relates to a smoke generator for a toy, primarily passive toys, which the blower for blowing smoke out of the smoke generating chamber operates intermittently and mechanically, simultaneously with the generation of the smoke, so that the operation of the battery used for smoke generation is also intermittent, thereby prolonging battery life. Also disclosed is a smoke generator wherein a metal film or carbon resistor is utilized to heat an oil containing wick to produce the smoke.
