Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

Referring to fig. 1, a computer keyboard cleaning device includes a motor 1, a first gear 2, a second gear 3, a conveyor belt 4, a centrifugal fan 5, a circular brush 6, a first dust-collecting pipe 7, a second dust-collecting pipe 8, a centrifugal duct 9, and a housing 10.

The shell 10 is square, the upper part and the lower part of the shell are respectively provided with a gap, the gap at the lower part is an air inlet of a centrifugal channel 9, dust is sucked into the centrifugal channel 9 through a first dust suction pipe 7 and a second dust suction pipe 8, and the shell is arranged behind a circular brush 6; the upper gap is an air outlet 901 of the centrifugal channel 9, and the air outlet 901 is connected to a dust collector, which is not shown in the figure.

Two gears, namely a first gear 2 and a second gear 3, are arranged on the housing 10, the first gear 2 is located below the air outlet 901, and the second gear 3 is located in front of the air inlet.

The first gear 2 is provided with a motor 1, and the motor 1 drives the first gear 2 and the centrifugal fan 5 to operate.
