Description

Technical Field

[0001] The utility model relates to an ultra-thin indoor silent fresh air fan which is easy to disassemble and assemble, and belongs to the technical field of fresh air systems. Background Art

[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and the indoor air is exhausted through the duct. The ductless fresh air system consists of a fresh air fan, which also purifies the outdoor air and introduces it into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of work, while the ductless fresh air system is more suitable for home use because of its easy installation.

[0003] Authorization announcement number (CN212039498U) discloses a silent fresh air blower, which relates to the technical field of fresh air blowers, including an air outlet duct, the inner wall of which is connected to a filter screen, the filter screen is connected to a dust removal mechanism for removing dust from the filter screen, and the dust removal mechanism includes a dust collection component for collecting dust. The technical problem to be solved is that when the filter screen is cleaned, the dust on the filter screen will fly into the duct, causing dust to be retained inside the duct. When the fresh air blower is started, the dust in the duct may be blown into the room. The utility model has the effect of cleaning and collecting the dust on the filter screen;

[0004] However, when the existing fresh air fans are in use, a large amount of dust and impurities will accumulate inside, so they need to be disassembled frequently for cleaning. However, the existing fresh air fans are not easy to disassemble quickly, and most of them still use the traditional fixing method of bolts and screw holes. This method requires people to hold a screwdriver. If the model of the screwdriver is different from the model of the bolt, it cannot be used at all, which easily brings trouble to people's disassembly work. In addition, the existing fresh air fans are usually equipped with filtering devices, such as activated carbon filter plates, but lack devices that can replace or clean the filtering devices, which brings inconvenience to users.

[0005] Therefore, an ultra-thin indoor silent fresh air blower which is easy to disassemble and assemble is proposed. Utility Model Content
