The fans installed in the computer actually use them to quickly conduct heat from the CPU and blow it into the nearby air.The cooling effect is directly related to the quality of the cooling fans and fins.However, because people do not often open the case to check and clean the fans and fan blades when using the computer, the dust in the case is too much.When the fan is in operation, it can achieve the cooling effect by absorbing the heat from the case and CPU and radiating the heat from the cooling fins, so the efficiency and life of the fan will be greatly affected if there is too much dust.

        The existing computer fan must be renewed after two years of consistent use without regular cleaning.The reason is that too much dust in the chassis has not been cleaned in time, resulting in a greatly reduced heat dissipation effect and shortened service life of the fan.What's more, the entire computer motherboard has been burnt down because dust has accumulated on the circuit board.In this regard, we propose the following anti-dust computer fan.

        In order to solve the technical problem and overcome the existing defects, the fan provides a dustproof computer fan, which drives the fan casing and fan blades to rotate through the rotation of the rotating shaft to generate air flow, the discharge network arranged inside the upper panel communicates current and generates an electrostatic field with the dust collection network arranged inside the lower panel to ionize the gas molecules passing through the discharge network into positive and negative ions and adsorb on the dust, and the charged dust moves toward the dust collection network under the action of the electrostatic field and finally adsorbs on the dust collection network and cannot enter the fan casing and the circuit board, thus effectively solving the problems in the above technology.

        The dustproof computer fan comprises a fan shell, a rotor, a stator, a fan seat, a rotating shaft and a circuit board, wherein fan blades are arranged outside the fan shell; a mirror base is arranged at the top of the fan shell; the stator is fixedly connected inside the fan shell; the fan seat is connected at the bottom of the fan shell; the rotor is arranged inside the fan shell; the rotating shaft is connected at the bottom of the rotor; the rotating shaft is fixedly connected with the circuit board; and levers are arranged at the four ends of the circuit board. The surface of the circuit board is provided with radiating fins. One end of the lever is fixedly connected with the upper panel, and a discharge net is arranged inside the upper panel. A lower panel is arranged below the upper panel, four ends of the lower panel are fixedly connected with levers, and a dust collection net is arranged inside the lower panel. One side of the circuit board is provided with a power cord which is electrically connected with a three-pin socket.

        Through the rotation of the rotating shaft, the fan shell and fan blades are driven to rotate to generate air flow.The discharge net arranged inside the upper panel communicates current and generates electrostatic field with the dust collection net arranged inside the lower panel, so that gas molecules passing through the discharge net ionize into positive and negative ions and are adsorbed on dust.Charged dust moves toward the dust collection net under the action of the electrostatic field and finally adsorbs on the dust collection net and cannot enter the fan shell and circuit board, greatly prolonging the service life of the computer fan.
