technical field

The invention relates to the technical field of high school learning appliances, in particular to a cleaning and processing device for chemical experiment test tubes for high school students.

Background technique

For high school students, more test tubes are often used in chemical laboratories. These test tubes need to be cleaned after use. In order to improve the existing cleaning method, machines are used instead of manual cleaning of test tubes to reduce the burden on students. Improve cleaning efficiency.

For example, the patent with the application number of 201920251094.8 discloses a chemical experiment test tube cleaning and processing device for high school students, including a cleaning box. The patent can effectively clean the inside of the test tube through the water distribution pipe head and the spray head, and the operation is simple.

For example, the patent with the application number of 201820098239.0 discloses a cleaning and processing device for chemical experiment test tubes for high school students, including an L-shaped fixed seat and an L-shaped sliding seat.
