The air inlet has a perforated base plate, and the air outlet has an openable air guide plate. Inside the housing, between the base plate and the air guide plate, arranged from top to bottom, are a pre-filter, a plasma generator, an adsorption filter, and a fan. Mounting plates are located on both sides of the housing, and a connecting plate is located at the bottom of each mounting plate. A motor is mounted on each mounting plate, and the motor has a rotating shaft with a gear section and a winding mechanism. The device comprises a line segment, a gear segment with a fixed gear, and a connecting wire wound around the line segment. The lower surface of the connecting plate abuts against the upper surface of the primary filter element. The connecting plate is provided with a wire-passing hole and a push rod hole. The end of the connecting wire passes through the wire-passing hole and connects to the primary filter element. A push rod is provided in the push rod hole. The lower end of the push rod contacts the upper end of the primary filter element. A rack that meshes with the gear is provided on the upper part of the push rod. A limit rod is fixed on the push rod. The primary filter element is provided with a first magnet. A second magnet corresponding to the first magnet is provided on the connecting plate. The base plate is detachably connected to the primary filter element.
[0007] With the above structure, when the pre-filter needs to be replaced, the motor is started, and the motor drives the gear to rotate, thereby driving the push rod downward, causing the pre-filter to disengage from the connecting plate. The push rod continues to descend until the rack and gear disengage. The pre-filter and the base plate gradually descend with the cable. After the pre-filter has descended to the appropriate position, it can be cleaned or replaced. After cleaning or replacement, the motor reverses, and the connecting cable pulls the pre-filter upward. The pre-filter contacts the lower end of the push rod and pushes the push rod upward. The rack and gear of the push rod contact and mesh, and the first magnet and the second magnet reconnect magnetically. This utility model makes it convenient and safe to replace the pre-filter at the air inlet.
[0008] Preferably, in order to facilitate the connection and disconnection of the pre-filter and the connecting plate, the pre-filter includes a frame and a filter body disposed within the frame, the first magnet is disposed on the frame, the lower end face of the top rod contacts the frame, and the end of the connecting line is connected to the frame.
[0009] Preferably, the base plate and the frame are detachably connected to facilitate the replacement of the pre-filter.
[0010] Preferably, in order to facilitate the replacement of the pre-filter, the base plate includes connecting parts arranged around the perimeter and a hollow part arranged in the middle, the lower end face of the frame is provided with a third magnet, and the upper end face of the connecting parts is provided with a fourth magnet corresponding to the third magnet.
[0011] Preferably, in order to ensure the transmission effect of the push rod, a baffle is fixed on the connecting plate, and the push rod is located between the gear and the baffle. Attached Figure Description

[0018] like Figures 1 to 5As shown, this utility model of a wall-mounted air purifier with easy filter replacement includes a housing 1. An air inlet 2 is located at the bottom of the housing, and an air outlet 3 is located at the top. A perforated bottom plate 4 is located at the air inlet, and an openable air guide plate 5 is located at the air outlet. Inside the housing, between the bottom plate and the air guide plate, from top to bottom, are arranged a pre-filter 6, a plasma generator 7, an adsorption filter 8, and a fan 9. The adsorption filter contains activated carbon for adsorption. Mounting plates 10 are located on both sides inside the housing. A connecting plate 11 is located at the bottom of the mounting plate. A motor 12 is mounted on the mounting plate. The motor has a rotating shaft 13, a gear section 14, and a winding section 15.
