Vaporizer ventilation structure

The utility model provides a vaporizer ventilation structure which comprises a vaporizer, a heating cavity, a hot air source storage cavity and a box type frame, the vaporizer is installed in the box type frame, every four adjacent and rectangular fin heat exchange pipes form a heat exchange space, the top of the hot air source storage cavity is communicated with a plurality of hot air pipes, and the hot air pipes are communicated with the box type frame. The hot air pipe extends upwards into the heat exchange space, and air holes are formed in the pipe wall of the hot air pipe. An electric heating element is arranged in the heating cavity, and the heating cavity is communicated with the hot air source storage cavity through an air supply pipeline. By means of the design, the heat exchange space is heated, it is guaranteed that the heat exchange space is smoothly communicated with outside hot air, the temperature of the heat exchange space is increased, the fin heat exchange pipes are prevented from being fro
