[0004] The device uses a ventilation and drying component to turn on the power of the heating wire and exhaust fan when the humidity in the air is high, and sends the heated and dry air filtered by the filter cotton into the interior of the storage device, effectively reducing the degree of reaction between the sample and the moisture in the air, increasing the accuracy of the subsequent experimental test data, and making the design more user-friendly. In addition, the fixed component can fix the storage rack through the extrusion force of the spring, increasing the friction between the storage rack and the inner wall of the storage device, increasing the stability of the storage rack when the storage device is moved, and preventing the storage rack from shaking and affecting the chemical samples on the storage rack. However, the device needs to pull out the storage rack when removing the sample. During this process, the storage rack is not supported, which can easily make the sample on the top of the storage rack unstable when it is removed, making it inconvenient to sample the chemical sample.
