Abstract

The invention relates to a biological safety cabinet with a leakage alarm function, and relates to the field of cleaning equipment.The biological safety cabinet comprises a safety cabinet body, the safety cabinet body comprises a cabinet body, a shielding door and a power mechanism driving the shielding door to ascend and descend, and the power mechanism comprises a driving roller set and a power part; the driving roller set is rotationally connected to the cabinet body and provided with a gap allowing the shielding door to abut against and penetrate through, and the power part is used for driving the driving roller set to rotate. An airflow alarm is arranged on the inner side of the bottom of the shielding door, an ultraviolet irradiation assembly is arranged at the position, located on one side of the shielding door, of the safety cabinet body, the airflow alarm is electrically connected with the ultraviolet irradiation assembly, and the ultraviolet irradiation assembly can emit light to cover an opening where the shielding door is opened. The device has the advantages of giving an alarm and carrying out protection treatment when the air quality exceeds the standard due to leakage.

Description

technical field [0001] This application relates to the field of clean equipment, in particular to a biological safety cabinet with a leakage alarm function. Background technique [0002] The biological safety cabinet is a kind of air purification negative pressure equipment that prevents the aerosol dissipation of dangerous particles involved in the experimental operation process. The principle is to form a negative pressure through suction and protect the staff through the vertical airflow. The outside air enters the safety cabinet after being filtered to prevent the samples from being polluted by the air. [0003] For related technologies, see the patent of CN113368908A, which discloses a high-safety biological safety cabinet, including a biological safety cabinet body, a control panel with a face recognition device and a screen door with a servo motor. Alarm, the servo motor on the screen door is connected with the airflow alarm. The technician sits on the pulley to ope...
