Medical sterilizer by vaporization of lactic acid

The utility model relates to a medical sterilizer by the vaporized lactic acid, comprising a base seat 1, a supporting frame 2, and an electro-heat disk 3. The supporting frame 2 is fixedly connected between the base seat 1 and the electro-heat disk 3. A counterweight type magnetic control switch 8 is arranged on the electro-heat disk 3 by a fixed fulcrum 5. A dry reed pipe 10 is arranged on the base seat 1 by a fixed rod 11. When a metallic cylinder 4 contained with lactic acid solution is positioned on the electro-heat disk 3, a lever 6 is pressed to lift, a magnet 9 approaches to the dry reed pipe 10, and the contact point of the dry reed pipe 10 is closed, so that the electro-heat disk 3 obtains the electricity for work. The lactic acid solution is vaporized by heating, the weight is gradually lightened, when the definite quantity is reached, the lever 6 is downwards pressed by counterweight iron 7, the magnet 9 leaves the dry reed pipe 10, the contact point of the dry reed pipe is disconnected, so that the electro-heat disk 3 is stopped to heat. The utility model can not have the problems of raw material waste, etc.
