Computer heat dissipation plate cleaning device and cleaning method

The invention provides a computer heat dissipation plate cleaning device (100) and a cleaning method (200), which are applied to the field of computers. The cleaning device (100) comprises a frame (34), a pair of brushes (12) accommodated in the frame (34), a first motor (36), a cleaning mechanism (3) of a driving unit (10) for converting the torque of the first motor (36) into the torque of the pair of brushes (12) so as to enable the brushes (12) to rotate towards the middle at the same time, a dust collection mechanism (5) provided with a second motor (54), an impeller (53) and a dust collection bin (51) surrounding the outer side of the impeller (53), and a receiving mechanism (4) used for collecting dust. When the second motor (54) is started, airflow from the cleaning mechanism (3) to the receiving mechanism (4) through the dust collection bin (51) is generated in an inner cavity (513) of the dust collection bin (51). According to the technical scheme provided by the invention, dust on the heat dissipat
