The brushing assembly 200 has a brush 240 that is used to contact the workpiece to be dust-cleaned; the driving assembly 300 is connected to the brushing assembly 200 and is used to drive the brushing assembly 200 to rotate so that the brush 240 brushes the workpiece to be dust-cleaned.

[0053] In this embodiment, by providing the blowing and cleaning assembly 100 with the blowing port 122 facing the workpiece to be dust-cleaned, blowing and dust-cleaning of the workpiece to be dust-cleaned can be achieved, and the dust that is not adhered to the surface of the workpiece to be dust-cleaned can be blown away. By providing the brushing assembly 200 and the driving assembly 300; the driving assembly 300 is connected to the brushing assembly 200, the driving assembly 300 can be started, and then the brushing assembly 200 can be driven to rotate, so that the brush 240 can remove the dust adhered to the workpiece to be dust-cleaned. Coupled with the blowing of the blowing and cleaning assembly 100, the dust brushed off by the brush 240 can be removed in time, solving the problem that the suction method in the prior art cannot clean the dust and impurities firmly adhered inside the electrical control cabinet.

[0054] It can be understood that in this embodiment, there is no limitation on the workpiece to be dust-cleaned, and the workpiece to be dust-cleaned includes but is not limited to an electrical control cabinet.

[0055] It should be noted that since this embodiment uses a combination of blowing and brushing to clean the workpiece to be dust-cleaned, the flatness of the surface of the workpiece to be dust-cleaned is not limited. In other words, even if the surface of the workpiece to be dust-cleaned has structures such as grooves and gullies, the dust cleaning device of this embodiment can also clean the dust in the grooves.

[0056] In some embodiments, the purging assembly 100 includes a handle tube 110, a purging tube 120, and an air pump 130. The handle tube 110 has a first installation cavity 111 inside. The purging tube 120 has a blowing channel 121 inside; one end of the purging tube 120 is disposed in the first installation cavity 111 and is connected to the driving assembly 300; the other end of the purging tube 120 is located outside the first installation cavity 111 and is provided with a blowing port 122 communicating with the blowing channel 121; an air vent 123 is provided on the side surface of the purging tube 120, and a first gap is formed between the side surface of the purging tube 120 and the inner wall of the first installation cavity 111, and the air vent 123 is used to communicate the first gap and the blowing channel 121; the cleaning brush assembly 200 is located outside the first installation cavity 111 and is connected to the side surface of the purging tube 120; the driving assembly 300 drives the cleaning brush assembly 200 to rotate through the purging tube 120. The air pump 130 is installed on the handle tube 110, and the air outlet of the air pump 130 is communicated with the first gap for blowing air into the first gap so that the air blows out from the blowing port 122.

[0057] In this embodiment, by connecting both the driving assembly 300 and the cleaning brush assembly 200 to the purging tube 120, the driving assembly 300 can drive the cleaning brush assembly 200 to rotate through the purging tube 120, so as to realize cleaning the workpiece to be dusted while blowing the dust generated by the cleaning in time and blowing the dust out of the workpiece to be dusted. By disposing a part of the purging tube 120 in the first installation cavity 111 and forming a first gap with the inner wall of the first installation cavity 111; by connecting the air outlet of the air pump 130 to the first gap, when the purging tube 120 rotates, the rotation of the air pump 130 is avoided, simplifying the connection structure between the purging tube 120 and the air pump 130, and at the same time ensuring that the air pump 130 can blow air into the purging tube 120 to realize the purging of the workpiece to be dusted.

[0058] Specifically, when the air pump 130 is started, the air pump 130 blows air into the first gap; because the air vent 123 is used to communicate the first gap and the blowing channel 121, the air can enter the blowing channel 121 from the air vent 123 and finally blows out from the blowing port 122 to realize the purging of the workpiece to be dusted.

[0059] As Figure 4 shown, further, the handle tube 110 further has a second installation cavity 112 inside; the second installation cavity 112 is located on the side of the first installation cavity 111 away from the purging tube 120; there is a partition between the first installation cavity 111 and the second installation cavity 112.

The control switch 700 includes a first switch 710 and a second switch 720; the first switch 710 is electrically connected to the driving component 300 for controlling the start and stop of the driving component 300. The second switch 720 is electrically connected to the air pump 130 for controlling the start and stop of the air pump 130.

[0064] Further, a T-shaped rubber plug 113 is detachably provided at the right end opening of the second installation cavity 112. By providing the T-shaped rubber plug 113, the second installation cavity 112 can be opened or closed as needed, which is convenient for replacing the storage battery 600.

By providing the sealing bearing 140, the rotational stability of the blowing and cleaning pipe 120 can be improved, and at the same time, the effective space volume of the first gap can be reduced, so that the air entering the first gap can enter the blowing and cleaning pipe 120 more quickly.

[0066] Specifically, along the axial direction of the blowing and cleaning pipe 120, two sealing bearings 140 are arranged at intervals in the first gap.

[0067] Further, a plurality of ventilation holes 123 are provided on the side surface of the blowing and cleaning pipe 120; the plurality of ventilation holes 123 are arranged along the circumferential direction of the blowing and cleaning pipe 120.

[0068] Specifically, four ventilation holes 123 are provided on the side surface of the blowing and cleaning pipe 120; the four ventilation holes 123 are evenly distributed along the middle circumferential direction of the blowing and cleaning pipe 120.

[0069] In some embodiments, the cleaning assembly 200 includes an annular connector 210, a first connector 230, and a plurality of brushes 240.
