[0002] Axial flow fans are widely used. They are fans in which the airflow direction is in the same direction as the axis of the fan blades. For example, electric fans and air conditioner outdoor fans are axial flow fans.

[0003] At present, a Chinese utility model with a publication number of CN220979885U discloses a dust-proof axial flow fan, including a wind tube, a first driving member, a first fan blade, a filter assembly, a driving assembly and a cleaning assembly, wherein the first driving member is installed in the wind tube, and the first driving member drives the first fan blade to rotate to suck airflow from one end of the wind tube and blow it out from the other end of the wind tube; the filtering assembly includes a partition plate, and a plurality of ventilation holes are distributed circumferentially along the rotation axis of the first fan blade on the partition plate, and the filter plate is installed in the ventilation hole; the cleaning assembly includes a cleaning cover, a cleaning fan and a toggle rod, the cleaning fan is installed in the cleaning cover, and the cleaning fan is used to convey airflow to one side of the opening of the cleaning cover, the cleaning cover is fixedly connected to the toggle rod, and the toggle rod is elastically rotatably connected to the partition plate; the driving assembly is used to toggle the toggle rod to rotate; a dust-proof axial flow fan is designed, the airflow is filtered by the filtering assembly, and the driving assembly and the filtering assembly cooperate to clean the filter plate, thereby improving the dust-proof effect of the axial flow fan.

[0004] However, the existing axial flow fans cannot effectively filter dust and fluff, and are not convenient for disassembling and cleaning the dust screen. At the same time, they cannot effectively limit the installation according to the wall thickness. To solve the above problems, we provide a dustproof axial flow fan. Utility Model Content

[0005] The purpose of the utility model is to provide a dustproof axial flow fan to solve the problems raised by the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a dustproof axial flow fan, comprising a shell, a motor is arranged inside the shell, a fan blade is bolted to the output end of the motor, a ring is arranged on one side of the shell, a dustproof net is bolted inside the ring, a metal rod is bolted to one side of the ring, a socket matched with the metal rod is opened on one side of the shell, a magnetic block is bolted inside the socket, a mounting plate is bolted to the surface of the shell, and a movable plate is sleeved on the surface of the shell and the screw.

[0007] Using the above technical solution: the user can start the motor to drive the fan blades to rotate, and then the external air filters the dust and fluff through the dustproof net. The user can pull the ring so that the ring drives the metal rod out of the inside of the socket, so that the socket is separated from the magnetic block. This can effectively facilitate the filtration of dust and fluff, and also facilitate the disassembly and cleaning of the dustproof net. The user inserts the shell and the screw into the wall, and then sockets the movable plate with the shell and the screw outside the wall. Then, turn the nut to move on the surface of the screw, and at the same time push the movable plate to move on the surface of the shell and the screw, so that it can effectively facilitate the limited installation according to the thickness of the wall.

[0008] The utility model is further configured that a nut is threadedly connected to the surface of the screw.

[0009] By adopting the above technical solution, the movable plate can be effectively limited by setting the nut.

[0010] The utility model is further configured that a round hole matching the screw rod is opened inside the shell.

[0011] The above technical solution is adopted: by setting the round hole, it can be effectively used in conjunction with the screw.

[0012] The utility model is further configured that a protective net is bolted to one side of the shell.

[0013] By adopting the above technical solution: the fan blades can be effectively protected by setting a protective net.

[0014] The utility model is further configured that a bracket is bolted inside the shell, and a limiting frame is bolted on the top of the bracket.

[0015] By adopting the above technical solution, the limit frame can be effectively supported by arranging a bracket.

[0016] The utility model is further configured that one side of the limit frame is bolted to the motor.

[0017] By adopting the above technical solution, the motor can be effectively installed by setting a limit frame.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The user can start the motor to drive the fan blades to rotate, and then the external air will filter the dust and fluff through the dust net. The user can pull the ring to drive the metal rod out of the socket, so that the socket and the magnetic block are separated. This can effectively filter the dust and fluff, and also facilitate the removal and cleaning of the dust net;

[0020] 2. The user inserts the housing and the screw into the wall, and then sleeves the movable plate with the housing and the screw outside the wall. Then, the nut is screwed to move on the surface of the screw, and the movable plate is pushed to move on the surface of the housing and the screw, so that the installation can be effectively limited according to the thickness of the wall.
