[0002] Microbiological testing is the process of identifying, counting and detecting microorganisms. It can detect and analyze the types and quantities of microorganisms in samples to determine whether pathogens, harmful bacteria or other target microorganisms are present. When conducting quantitative bacterial testing, the solid preparation sample must first be made into a homogenate and then tested to obtain accurate results. The process of making the homogenate is mostly a manual operation. In order to improve the efficiency of homogenate preparation, corresponding homogenization devices will also be used.

[0003] According to the utility model with authorization announcement number CN215975762U, a homogenizing device for microbial testing in a disease control center is disclosed. Although the homogenizing device is arranged in combination with a storage cylinder, a sealing cover, a stirring blade and a connecting groove, it can not only prevent the sample from being contaminated by contact with air during stirring, thereby affecting the accuracy of the test result, but also facilitate the user to clean the stirring blade and the storage cylinder after testing the sample, thereby improving the working efficiency of the homogenizing device and avoiding the need for the user to clean the stirring blade every time after using the homogenizing device, thereby effectively improving the practicality of the device. However, its structure is complex and huge, and it is also more troublesome to use. There is a lack of a simple and portable homogenizing structure, resulting in a high time cost for medical staff to learn how to use it and poor portability. To this end, we provide a homogenizing device for microbial testing to solve the above problems. Utility Model Content
