Abstract

An improved structure of a smoke generator including a housing and a pump accommodated in the housing. The pump pumps a chemical solution in a container via a solution duct to a heating vaporization device. The heating vaporization device includes two opposed disposed heat insulation rings, a heating tube, and a power source. The heat insulation rings are metal rings of good electrical conductivity and have a periphery provided with a plurality of ring holes. A plurality of metal conductive wires each have two ends respectively connected to the opposedly arranged ring holes, with a coil formed in a center of each heat insulation ring. The heating tube is a metal tube of a high resistance coefficient and is mounted intermediate of the heat insulation rings. A solution inlet and a smoke ejecting end at both ends of the heating tube pass through and are secured in the coils on the same side. A vaporization section of the heating tube is disposed intermediate of the solution inlet and smoke ejecting end and configured to be winding. The solution inlet receives the solution transported via the solution duct to allow the solution to undergo vaporization in the vaporization section. Smoke formed within the vaporization section is ejected via the smoke ejecting end. The power source is pivotally connected to a circuit board and is further connected to the pump and the heating vaporization device to achieve connection of a control circuit. Two connecting wires of the circuit board are respectively connected to the heat insulation rings so that electric currents pass through the lead wires, coils, and the heating tube therebetween to achieve connection of the circuit. The heating tube forms resistance to generate high temperature that vaporizes the solution flowing therethrough. The smoke thus generated is ejected from the smoke ejecting end.
