[0002] An electronic balance is a precision weighing product with the highest accuracy, the smallest measuring range, and the lowest scale value for weighing slight weights. Electronic balances have been widely used in various fields of research and production.

The sealing cover structure includes a sealing cover, and a conveying shell is obliquely arranged at the top of the sealing cover. The lower end of the conveying shell penetrates through the sealing cover to the inside of the sealing cover. By the obliquely arranged conveying shell, the utility model enables the sample to generate friction force when moving in the conveying shell, reduces the moving speed of the sample, thereby reducing the kinetic energy of the sample, and thus reducing the acting force generated when the sample falls onto the weighing structure, ensuring the accuracy of the sample mass during measurement.
