Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high-temperature resistant internal and external circulation fan. Background Technique

[0002] A fan is a device that converts mechanical energy into gas power, mainly used to transport gas from one place to another, and can also be used to compress gas to increase its pressure. The application fields of fans are very extensive, including air conditioning, refrigeration, ventilation, transportation, cleaning, etc. Among them, the internal and external circulation fan is a fan that can carry out air flow in a closed space, mainly used in the ventilation and air change of factory workshops, indoor air purification, ships and other fields. It realizes the continuous update of indoor air by introducing fresh air into the room and discharging dirty air at the same time, thereby improving the indoor air quality.

[0003] When the traditional internal and external circulation fan is in use, it usually replaces the outside air with the turbid air in the room to maintain the indoor air quality. However, there is some dust attached to the outside air. During the process of the fan bringing the outside air into the room, it is necessary to filter and adsorb the dust in the air through a filtering device. When filtering the dust in the air for a long time, a large amount of dust will accumulate on the surface of the filtering device. The accumulated dust easily causes the filtering device to become blocked, affecting the filtering effect, and thus reducing the indoor air quality. Content of the Utility Model
