Module structure capable of automatically replacing filter screen and fresh air ventilator

Abstract

The invention discloses a module structure capable of automatically replacing a filter screen and a fresh air ventilator. The module structure comprises an upper mounting plate, a lower mounting plate, a partition plate, a filter screen guide part and a filter screen replacement mechanism; the partition plate divides a filter mounting gap between the upper mounting plate and the lower mounting plate into a filter side and a mounting side; the filter screen replacement mechanism comprises a filter screen recovery winding drum and a filter screen release winding drum which are arranged on the mounting side, a filter screen replacement driving component used for driving the filter screen recovery winding drum to rotate, and a roll-type filter screen wound on the filter screen release winding drum, the roll-type filter screen is provided with an opening end, the opening end enters the filter side from the mounting side to wind around the filter screen guide part and then enters the mounting side from the filter side to wind on the filter screen recovery winding drum, a filter cavity is defined by the roll-type filter screen on the filter side, the upper mounting plate, the lower mounting plate and the partition plate, and the upper mounting plate and/or the lower mounting plate are/is provided with air openings/an air opening communicating with the filter cavity. The fresh air ventilator comprises the module structure capable of automatically replacing the filter screen.

Description

technical field [0001] The invention relates to the field of fresh air system filtration, in particular to an automatic replacement filter screen module structure and a fresh air fan. Background technique [0002] The filter module in the fresh air product is the core module of the product. After the product is used for a period of time, the filter screen will be polluted and blocked, requiring maintenance and replacement. In a normal use environment, the filter replacement frequency is generally 3-4 times a year, and in some harsh use environments, the replacement frequency is as high as 6-8 times a year, and the cost of filter consumables and maintenance labor costs are relatively high. Although there are also some devices that can automatically replace the filter screen on the market, when the existing automatic filter screen replacement device is installed on the fresh air product equipment, the installation is more complicated, the maintenance is inconvenient, the modul...
