If measures are not taken to properly handle these gaseous pollutants, they will pose a hazard to the experimental operators and cause pollution to the indoor air environment and atmosphere. Therefore, fume hoods have become an ideal solution for laboratories.

[0003] The most widely used desktop exhaust gas treatment equipment at present has a basic working principle of pumping the exhaust gas generated on the central test bench through the ventilation ducts inside the building to the exhaust vents on the roof, and then discharging it into the atmosphere after centralized filtering and treatment. It has a good comprehensive effect on related experimental applications that produce a large amount of polluted gases that are not very harmful, and can use existing ventilation ducts and ventilation control systems to partially reduce the purchase and installation costs. However, the existing ventilation equipment has high construction and installation costs, requires a large number of ventilation ducts and engineering operations, and its reliability is difficult to guarantee. The sealing performance of each device and its connecting parts on the entire ventilation path must be very reliable to ensure the reliability of the system, and the energy consumption is large and the energy utilization rate is low. In particular, when the indoor constant temperature airflow is replaced by outdoor air, a large amount of air conditioning energy consumption is brought about. Therefore, the inventor proposes a desktop double-sided operation filtering ductless ventilation device to solve the above problems. Utility Model Content
