[0026] Furthermore, one end of the multiple sets of cleaning plates 5 are all arc-shaped, and the outer surfaces of the multiple sets of cleaning plates 5 are wrapped with rubber. The arc-shaped end can pass through the heat sink more smoothly, reducing the friction with the edge of the heat sink, avoiding damage to the heat sink, increasing the friction between the cleaning plate 5 and the inner wall of the heat sink, and more effectively scraping off dust. At the same time, the rubber material is soft and will not scratch the heat sink.

[0027] Furthermore, the outer surface of the movable plate 9 is provided with a plurality of ventilation slots, which can clean the dust without hindering the heat dissipation effect of the heat dissipation plate, thereby ensuring the heat dissipation performance of the electrical instrument.

[0028] Furthermore, the motor 6 is fixedly connected to one side of the fixing base 912 to ensure the stability of the motor 6 when working and prevent the cleaning effect from being affected by vibration or movement.

[0029] Furthermore, the outer surface of the heat sink 2 is provided with a plurality of heat sinks, and the plurality of heat sinks are in the shape of long strips. The long strips of heat sinks provide a larger heat dissipation area, which is conducive to the rapid dissipation of heat. At the same time, this design is also convenient for cleaning with a cleaning plate.

[0030] Furthermore, the outer surface of the electrical instrument body 1 is provided with multiple groups of connection grooves 4, and the inner walls of the multiple groups of connection grooves 4 are installed with connection plates 3, the outer surface of the connection plates 3 is provided with bolts 7, and one side of the connection plates 3 is connected to the heat sink 2, and the heat sink 2 is detachably installed through the combination of the connection grooves 4, the connection plates 3 and the bolts 7. This design facilitates the cleaning or replacement of the heat sink, and improves the convenience of maintenance.

[0031] Furthermore, both sides of the movable plate 9 are provided with slide grooves, and the slide grooves are engaged with the slide rails 811. The slide rails 811 are installed on both sides of the inner walls of the cavity of the electrical instrument body 1. The slide rails 811 ensure the stability and accuracy of the movable plate 9 during movement, and prevent the cleaning effect from being affected by shaking or deviation. At the same time, it also reduces the friction between the movable plate 9 and the electrical instrument body, thereby extending the service life.

[0032] Working principle: When a large amount of dust accumulates in the heat dissipation groove on the outer surface of the heat dissipation plate 2, the driving motor 6 is started. The motor 6 drives the screw rod 8 to rotate. Since the two ends of the screw rod 8 are respectively mounted on the support seat 911 and the fixed seat 912 through bearings, the rotational movement of the screw rod 8 can be carried out stably. As the screw rod 8 rotates, the movable plate 9 moves on the screw rod 8 through the threaded structure inside it that cooperates with the screw rod 8. The moving direction of the movable plate 9 can be controlled according to the forward and reverse rotation of the motor 6, so as to realize the back and forth movement of the movable plate 9 in the cavity. During the movement of the movable plate 9, the multiple groups of cleaning plates 5 fixed on its outer surface also move accordingly. The size and shape of these cleaning plates 5 match the heat dissipation groove on the outer surface of the heat dissipation plate 2, so that the cleaning plates 5 can accurately pass through the heat dissipation groove. When the cleaning plates 5 pass through the heat dissipation groove, their surfaces contact the inner wall of the heat dissipation groove, thereby scraping off the dust accumulated in the heat dissipation groove.
