Abstract:
A smoke generator, comprising a housing accommodating therein a container containing a chemical solution and a heating vaporizing device, said heating vaporizing device being connected to a first end of a heat-resisting tube, a second end of said heat-resisting tube being connected to a transfer tube via an engaging hole so as to form a transfer path for the chemical solution;a drawing device provided between said container and said transfer tube for pumping the chemical solution from the container to the heat vaporizing device through the heat-resisting tube, the drawing device including: a hollow tube fitted with a fastening ring member, and a core rod with an elastic ring connected thereto, said core rod being provided with a through rod hole; a sealing cap abutting against said fastening ring member; a hollow pump being coupled with said fastening ring member such that said sealing cap is sandwiched therebetween, said elastic ring abutting against the inner wall of said pump, wherein said pump has a spring disposed therein between said core rod and a bottom portion of said pump, and a plug ball removably closing a pump hole in the bottom portion of said pump, the bottom portion of said pump being further provided with an extension tube for extension into the bottom portion of said container; said hollow tube having a top portion fitted with a press member which is formed with a liquid outlet in a lateral side thereof for connection with said transfer tube; said sealing cap connected with a coupling portion at a top portion of said container, whereby, by pressing and releasing said press member the solution within said container is pumped into said transfer tube by said pump and flows through said heat-resisting rube into said heating vaporizing device, the solution being vaporized to form smoke that is ejected via a nozzle.
