[0002] The principle of the homogenizer is to mix the experimental sample and solution or solvent evenly to achieve the standard solution required by the experiment.

[0003] Publication No. CN214598657U discloses a homogenizer, which solves the problem that the original operating device is exposed to the outside for a long time, which easily causes damage to the operating device and increases the cost through the coordinated arrangement of a sliding cover, a mounting slot and a magnetic column. However, when using this homogenizer, the container and the mechanism after homogenization need to be manually cleaned. After use, the container and the homogenizing mechanism need to be manually removed for cleaning before the next homogenization operation can be performed, which is quite time-consuming. Therefore, we propose a homogenizer with an internal cleaning and scraping structure. Utility Model Content
