[0011] Beneficial Effects

[0012] Compared with the prior art, the utility model has at least the following advantages:

[0013] When the exhaust fan in the utility model works, the air is filtered out of large dust particles through the primary filter of the air inlet cylinder and the secondary filter of the air inlet pipe, enters the connecting pipe, is sterilized by ultraviolet irradiation, enters the disinfection box, and is mixed with the ozone input by the ozone generator in the disinfection chamber, and then flows through the mixing chamber. The multiple retaining rings of the mixing chamber are set to extend the flow path of the gas, so that the gas and ozone are fully mixed and fully disinfected. The sterilized gas enters the filter chamber through the return air pipe, is heated by the heater, and the decomposition of ozone is accelerated. The air is filtered out of smaller and tiny particles through the secondary filter and the final filter, and the secondary filter is an activated carbon filter to further ensure the decomposition of ozone. The gas after disinfection and sterilization is discharged from the exhaust port at the bottom of the filter chamber. The utility model is filtered through 4 layers to fully filter out impurities in the air. After dual sterilization and disinfection by ultraviolet disinfection and ozone disinfection, the disinfection is more thorough. The ozone is heated by the heater and the activated carbon filter to ensure the full decomposition of ozone. The utility model extracts, disinfects and purifies the air in the workshop from four directions, and then discharges the treated air downward. Compared with directly discharging ozone into the air for disinfection, the utility model has better disinfection effect and less harm. BRIEF DESCRIPTION OF THE DRAWINGS
