Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, in particular to a sterilization device. Background Art

[0002] In the biological laboratories of universities, test tubes are often needed for various experiments and tests. Before the experiments and tests, the test tubes need to be sterilized and disinfected. China Patent Network CN202980768U provides a test tube brush with a sterilization device, especially a test tube brush that uses an ultraviolet sterilization device to sterilize the cleaned test tubes. A cleaning brush is installed on the upper part of the test tube brush, and a shell is provided at the lower part. An ultraviolet sterilization device is installed inside the shell. The ultraviolet sterilization device relies on a wire to connect the power supply, and the power supply is connected to a switch outside the shell. After the test tube is cleaned with the cleaning brush, the ultraviolet sterilization device is used to sterilize the cleaned test tube. When the device needs to sterilize the test tube, the test tube must be removed from the surface of the cleaning brush, and then placed in the ultraviolet sterilization device for sterilization and cleaning. In this way, the process of repeatedly moving the test tube is not only time-consuming and laborious, but also the ultraviolet sterilization device has a sterilization dead corner, and it cannot guarantee that the inner wall of the test tube has a good sterilization effect, which needs to be improved.

[0012] 1. In the utility model, by setting the gear, water pipe, offset brush and inner tube structures, in order to improve the sterilization effect on the test tube, the device is designed with a special sterilization treatment structure. The inner tube and the offset brush will rotate under the drive of the gear. The user can first insert the inner tube and the offset brush into the test tube, and then start the motor. The motor will drive the gear to rotate, and then the inner tube and the offset brush will rotate inside the test tube. At the same time, the user can transfer the sterilizing liquid from the water pipe to the inner tube. In this way, when the offset brush cleans the inner wall of the test tube, the sterilizing liquid in the inner tube will be discharged from the water outlet. Such a design can not only sterilize the test tube, but also there is no sterilization dead corner in the sterilization process.

[0013] 2. In the utility model, by providing the workbench, protrusions, grooves, storage slots and other structures, in order to facilitate users to take and place pre-treated test tubes, users can place the pre-treated test tubes in the storage slots on the surface of the workbench, and the workbench can slide freely on the surface of the base. The principle is that the workbench and the base are connected by protrusions and grooves, and the protrusions can not only slide in the grooves, but also the grooves can limit the protrusions. Such a design can ensure that the workbench will not be misplaced or detached during the sliding process. Such a design is to facilitate users to take and place processed and pre-treated test tubes.
