Description

Technical Field

[0001] The utility model relates to the technical field of magnetic suspension fans, in particular to a magnetic suspension fan control component. Background Art

[0002] Currently, fans on the market use traditional bearing support structures, which have problems such as large mass, high noise, and high maintenance costs. In order to overcome these problems, magnetic levitation technology has been widely used in the fan field.

[0003] Publication number CN217275620U retrieved discloses a magnetic levitation fan for stabilizing a kiln system, including a bellows shell, the bellows shell being a box structure with an internal cavity; a support mechanism, the support mechanism being two groups, symmetrically arranged on the bottom surface of the bellows shell; a wind force mechanism, the wind force mechanism being arranged in the middle position of the front face of the bellows shell, for sucking air into the internal cavity of the bellows shell; an air outlet, the air outlet being arranged in the middle position of the top face of the bellows shell, for discharging the air in the internal cavity of the bellows shell to form wind force; and a maintenance mechanism. The utility model is applicable to a kiln system, and air can be sucked into the internal cavity of the bellows shell by the wind force mechanism, and the air in the internal cavity of the bellows shell is discharged from the air outlet, so that the magnetic levitation fan can provide air for the kiln system, and ensure the stability of the kiln system; the maintenance mechanism can expand the internal cavity of the bellows shell, so that the bellows shell is convenient for cleaning dust, and the maintenance cost is reduced.

[0004] There is still insufficient support when CN217275620 is used. While the interception net is filtering dust from the airflow sucked by the magnetic levitation fan, the dust on the interception net gradually accumulates, thereby reducing the airflow rate. The air intake cannot be stably regulated, affecting the use of the equipment. For this reason, we propose a magnetic levitation fan control component to solve the existing problem. Utility Model Content

[0005] The purpose of the utility model is to propose a magnetic suspension fan control component in view of the problems existing in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic levitation fan control component, comprising a shell, a rotating shaft, a magnetic levitation fan body, a transmission shaft and a mounting ring, the magnetic levitation fan body is arranged inside the shell, an output shaft is arranged at one end of the magnetic levitation fan body, a mounting ring is arranged inside the shell, a transmission shaft is arranged inside the mounting ring, driven gears are arranged at both ends of the transmission shaft, an output gear is arranged on the outer wall of the output shaft, a gear ring is arranged on the inner wall of the mounting ring, a rotating shaft is arranged on one side of the mounting ring, a grid plate is arranged at the inner opening of the shell, an interception net is arranged on one side of the grid plate, a rotating plate is arranged at one end of the rotating shaft, and brushes distributed in a rectangular array are arranged at one end of the rotating plate.

[0007] When using a magnetic levitation fan control component in the present solution, the magnetic levitation fan body drives the output shaft to rotate, and the internal impeller sucks the air to achieve the air supply effect. When the airflow passes through the interception net, the dust inside the airflow is intercepted, and the rotating shaft drives the output gear to push the driven gear. Because the transmission shaft is supported by the bracket for rotation, the two driven gears achieve stable rotation, and the other driven gear pushes the ring gear. The rotational force of the ring gear acts on the ball, and the ball supports the mounting ring for rotation. The connecting rod is connected to drive the rotating shaft to rotate, drive the rotating plate and the brush to rotate, and the brush contacts the outer wall of the interception net to brush away the adhered dust.

[0009] Preferably, the output gear meshes with the corresponding driven gear. The output gear meshes with the driven gear and pushes the driven gear when rotating.

[0010] Preferably, the gear ring is meshed with the corresponding impulse gear, and the driven gear drives the gear ring.

[0011] Preferably, the shell has balls distributed in an annular array rotatably mounted inside, the outer wall of the mounting ring is provided with an annular rolling groove, and the balls are rollingly mounted inside the rolling groove. The balls rotate inside the rolling groove, providing a rotatable rolling support for the mounting ring inside the shell.

[0012] Preferably, the outer wall of the rotating shaft is provided with connecting rods distributed in a ring array, one end of the connecting rod is connected to the outer wall of one side of the mounting ring. The connecting rod connects the mounting ring and the mounting shaft together.
