[0002] The combined fresh air unit is an integrated air treatment system, mainly used to improve the air quality inside buildings and enhance energy efficiency. Its main function is to introduce external fresh air into the building interior. This fresh air system can remove particulate matter, pollen, dust, etc. in the air through filters, thereby improving the indoor air quality. Through the fresh air system, the old air indoors can be replaced regularly, reducing the concentration of pollutants and keeping the indoor air fresh. The high-efficiency ability of the combined fresh air unit enables the building to operate more effectively, reducing energy waste, lowering operating costs, and enhancing overall energy efficiency and sustainability.
[0003] Currently, the combined fresh air unit usually needs to use a filter screen to filter the air inlet. However, during the filtering process, the filter holes are easily blocked by dust and impurities, resulting in a decrease in the air intake volume and a reduction in the air treatment efficiency. In the long-term use, the fan blades of the fan will also adhere to dust, leading to a decrease in the air outlet quality. Currently, the combined fresh air unit is not convenient for quickly disassembling and maintaining the fan, and its portability is relatively low. Content of the Utility Model

The entered air is discharged through the air outlet 3 and enters the room to improve the indoor air quality. When the dust-proof net 203 needs to be maintained and cleaned, directly pull out the dust-proof net 203 upward and clean the dust and impurities on the surface of the dust-proof net 203. When the fan body 8 needs to be maintained, press the two sliders 906 to make them enter the centers of the sliding grooves 905, and then directly take out the plug rod 903 upward, releasing the fixation of the fixing plate 901 and the installation plate 902, and then take out the fan body 8 for maintenance.
