Description

A fume hood with gas purification function

Technical Field

The utility model relates to the technical field of fume hoods, in particular to a fume hood with a gas purification function.

Background Art

Cabinet exhaust hoods are commonly known as fume hoods, which are similar to closed hoods. Small parts spray paint cabinets and chemical laboratory fume hoods are typical structures of cabinet exhaust hoods. Large room fume hoods have one side completely open, and operators work inside the cabinet. They are mainly used for large-scale painting and powder bagging. However, after long-term use, the filter surface of the device that filters the gas is dirty, resulting in poor subsequent gas purification effect.

For example, publication number CN219464306U discloses a laboratory fume hood with a gas purification function. The device drives the screw to rotate by turning a knob, so that the slider slides and drives the filter plate to move out of the fume hood body. The filter plate can be easily removed from the slider through a sliding block, which is convenient for installation and disassembly and has strong practicality.

However, the above-mentioned filtering device cannot clean the filter plate while working, but needs to be stopped and then the filter plate can be removed from the slider by sliding the block for cleaning, which is less practical. In view of this, we propose a fume hood with gas purification function.
