Description

Technical Field

[0001] The utility model belongs to the technical field of test tube cleaning, in particular to a test tube cleaning and drying device for a laboratory. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories, used as reaction containers for small amounts of reagents. In experiments, test tubes are often used in large quantities to perform the required experimental operations. Test tubes need to be cleaned in time after use to ensure that no experimental reagents or water remain inside the test tubes, to avoid affecting the reaction of subsequent experimental uses, and to avoid the growth of bacteria and other substances due to long storage time, which may affect the experimental results.

[0003] At present, most of the cleaning methods are manual. Due to the small diameter and long length of the test tube, manual cleaning is troublesome, takes a long time to clean, and is difficult to clean. It is easy to cause the test tube to fall off and break. After cleaning, the water vapor is removed by inverted control drying, or the test tube is dried by a device that can generate hot air, such as a hair dryer. The current test tube drying device is not convenient for fixing the test tube, so that the hot air blows the test tube, which will cause the test tube to shake and collide and be damaged. In addition, the test tube dryer is not convenient for wiping the water droplets in the test tube, so the water droplets in the test tube evaporate slowly, affecting the test tube drying speed, and residual marks are left in the test tube. The entire cleaning and drying process has the disadvantages of being time-consuming, labor-intensive, and low work efficiency. However, professional test tube cleaning equipment cannot be widely used in small and medium-sized laboratories due to its high purchase price and high energy consumption. Summary of the invention
