The diameter of the first through hole is reduced by placing top ring covers with different diameters on the first through hole, so that an evaporating dish, a flask or a beaker which is matched with the diameter of the top ring cover can be placed on the top ring cover to heat the top ring cover.

Further, as shown in the drawing, the upper case 2 according to the present embodiment is made of a transparent PC engineering plastic. The PC engineering plastic is high temperature resistant and low in manufacturing cost.

Furthermore, as shown in the figure, the drainage device of the present embodiment includes a drainage pipe 33 and a valve 34 installed at an outer end of the drainage pipe 33, the drainage pipe 33 is installed on the lower casing 1, one end of the drainage pipe 33 is communicated with the inside of the lower casing 1, the other end of the drainage pipe 33 is communicated with the outside, and the valve 34 is installed at an outer end of the drainage pipe 33 in a matching manner. The water in the shell can be discharged out of the shell by opening the valve.
