Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a laboratory fume hood with disinfection and filtering functions for easy disassembly and cleaning, which solves the problem that the fume hoods currently on the market are usually used in the process of discharging laboratory waste gas in the above-mentioned background technology. The exhaust gas is not disinfected and filtered, which will cause the exhaust gas to pollute the environment, and the test exhaust gas will more or less leak through the gap of the glass door during the experiment, which will easily bring safety hazards to the experimenters

The invention discloses a laboratory fume hood with disinfection and filtration functions and convenient to disassemble and clean, and relates to the technical field of laboratory fume hoods. The laboratory fume hood comprises a body and a stepping motor; a control panel is arranged on the outer wall of the body, and a flow guide plate is arranged on the inner wall of the body; an air suction portis arranged on the outer surface of the flow guide plate; an ultraviolet lamp is arranged at the upper end of the outer wall of the flow guide plate; and a flow guide cavity is arranged at the gap between the flow guide plate and the body. According to the laboratory fume hood with the disinfection and filtration functions and convenience to disassemble and clean provided by the invention, a filter device is arranged, and a PP cotton filter element in the filter device can filter dust particles, colloidal impurities, organic pollution mineral impurities and the like with the diameter larger than five microns in gas, and an HEPA filter screen can be matched with an activated carbon screen to thoroughly and efficiently filter and deodorize pollutants such as smoke, dust and bacteria in thewaste gas, so that the filtered waste gas reaches the emission standard, and the environment is prevented from being polluted after emission.
Description
technical field [0001] The invention relates to the technical field of laboratory fume hoods, in particular to a laboratory fume hood with disinfection and filtering functions for easy disassembly and cleaning. Background technique [0002] The fume hood is an indispensable kind of laboratory furniture. It plays the role of exhaust and ventilation in the laboratory. When using it, people stand or sit in front of the cabinet, lower the glass door as much as possible, and stretch their hands through the door. Enter the cabinet for experiments, because the exhaust fan draws air inward through the open door, under normal circumstances, harmful gases will not overflow in large quantities, but the fume cabinet usually discharges the gas without treatment, which is easy to pollute the environment, so a laboratory Use a fume hood with a disinfection filter function for easy disassembly and cleaning. [0003] At present, the fume hoods on the market usually do not sterilize and filt...
