Abstract

The invention discloses a cylindrical filter screen for a fresh air fan, comprising a stepper motor, a driving gear, a filter screen support and a primary filter screen, the driving gear is mounted on the stepper motor, and the filter screen support It is in the shape of a hollowed-out cylinder, the filter holder is rotatably installed in the fresh air fan, the primary filter is bent into a cylindrical shape with a tooth shape, and the primary filter is detachably installed on the On the filter screen bracket, the primary filter mesh is meshed with the driving gear, and the cylindrical filter for the new fan can make full use of the entire effective area of ​​the primary filter, enhance the filtering effect, and improve the utilization rate of the primary filter.

Description

technical field [0001] The invention relates to the field of fresh air blowers, in particular to a cylindrical filter screen for fresh air blowers. Background technique [0002] The fresh air fan introduces the outdoor air with high oxygen content into the room through the fan to reduce the rising CO2 in the indoor closed environment. 2 value. Considering the different levels of dust and other impurities in the actual outdoor air, it is necessary to add a dust filter to achieve air filtration. Fresh air fans generally have primary effect, medium effect, high efficiency or other filters to achieve this purpose. [0003] Generally, there are two types of filter screens: flat type and discounted type. Since the discounted filter can better realize more filter screen area per unit volume, the discounted filter screen is adopted by many models. However, in order to pursue a larger expansion area, it is also necessary to enlarge the dimensions of the length, width, and thicknes...
