Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning return air vents, and more specifically, to an air-conditioning return air vent with a filtering device. Background Art

[0002] The air return vent of an air conditioner is a ventilation duct used to inhale indoor air for circulation and treatment by the air conditioning system. The return vent of a central air conditioner is usually installed on the indoor ceiling or wall and connected to the air duct of the air conditioning system. However, it still has some disadvantages in actual use, such as: most of the existing central air conditioner return vents are equipped with corresponding filtering devices to filter out dust, bacteria, pollen and other particles mixed in the inhaled air to prevent dust from entering the air conditioning equipment. After the filtering device has been used for a long time, it is often necessary to clean it. However, since the connection between the partial structure of the filtering device and the return air vent is fixed by bolts, etc., and the return air vent is set high in the room, it is inconvenient to disassemble the filtering device, which will delay the cleaning process and ultimately affect the normal use of the return air vent and the central air conditioner.
