Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for a biological safety cabinet. Background Art

[0002] The biological safety cabinet is a box-type air purification negative pressure safety device that can prevent the aerosol dispersion of certain dangerous or unknown biological particles during experimental operations. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, and biological products. It is the most basic safety protection equipment in the first-level protection barrier of laboratory biosafety.

[0003] After use, the biosafety cabinet needs to be disinfected and cleaned. Most of the existing methods are to manually spray disinfectant on the inner wall of the biosafety cabinet through a spray bottle, and then clean it with a cleaning cloth or oval forceps holding gauze. On the one hand, it increases the labor intensity of the staff and is time-consuming and laborious. On the other hand, it is troublesome and laborious to clean the deeper part of the safety cabinet. Some areas cannot be cleaned due to the limited length of human hands, which easily forms a cleaning blind spot. Therefore, it is necessary to use tools to clean the inside of the biosafety cabinet.

[0004] For example, "A biosafety cabinet cleaning device with good effect" disclosed in Chinese patent literature, with announcement number CN213495475U, includes a base plate, a cleaning mechanism, a support assembly and a column. The column is vertically arranged on the upper surface of the base plate, and the interior of the column is hollow. A slide groove is vertically opened on one side wall of the column, and a support assembly is slidably installed on the column with the slide groove surface, and the end of the support assembly facing away from the column is connected to the cleaning mechanism.

[0005] This cleaning device drives the cleaning cylinder to move in multiple directions through the cooperation of the cleaning mechanism and the supporting assembly, so that the interior of the safety cabinet does not need to be cleaned manually. However, there are still some shortcomings. On the one hand, only the operating table and the left and right side walls inside the safety cabinet can be cleaned, and the top and the rear wall cannot be cleaned, and the cleaning is not thorough. On the other hand, the cleaning effect is not good when a brush is used for cleaning, and there is residual cleaning liquid in the safety cabinet after cleaning. Utility Model Content
