Novel biosafety cabinet for teaching

Abstract

The invention discloses a novel teaching biological safety cabinet, which comprises a lifting device, a storage cabinet, a control room, a control keyboard, a power switch button and a refrigerator room. The lifting device is equipped with a lifting button on the surface, and a storage cabinet is installed above the lifting button. , an air intake device is installed above the storage cabinet, and an exhaust device is installed on the right side of the air intake device, a storage cabinet plate is installed on the surface of the storage cabinet, and a control room is installed under the storage cabinet plate, and a control room is installed under the control room Lighting equipment is installed, and a control keyboard is installed on the left side of the lighting equipment. In the present invention, by installing the lifting device, the lifting rod can adjust the biological safety cabinet to a suitable position only by adjusting the lifting button, so that students of different heights It is more convenient and faster to carry out biological experiments, and the functionality of the equipment is increased.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a novel teaching biological safety cabinet. Background technique [0002] At present, biological safety cabinets are indispensable in teaching equipment. How to master and understand the use of biological safety cabinets is very important and key to the study of biology. Students can do better when they master the relevant knowledge in this area. However, the current biological safety cabinets used in teaching still have some shortcomings. This kind of biological safety cabinet has a simple shape and structure, which cannot meet the needs of teaching well. It also has some problems in temperature control, which cannot be well To adjust the temperature, the height of ordinary biological safety cabinets cannot be adjusted, which cannot well meet the requirements of various elevated groups, and the functions are relatively single, which does not meet the needs of laborat...
