[0002] The experimental drying oven can be used to heat objects. It can heat the sample to the required temperature through the internal heating elements. There are many samples in the laboratory that need to be heated to ensure that the samples are in a dry state.

[0003] In the existing published technical literature, the utility model patent of Chinese patent publication number CN214620352U discloses an experimental drying box with an internal space adjustment mechanism. The patent mainly opens assembly grooves on both sides of the inner wall of the drying box, and a placement shelf is inserted in the middle position of the inner part of the drying box. Multiple groups of partition plates are adjusted to a suitable distance between each group of partition plates by adjusting blocks sliding horizontally in the adjustment grooves on the surface of the placement shelf, so as to divide the inner part of the drying box into multiple independent spaces, and effectively separate experimental instruments from each other; however, the drying box still has the following defects;
