[0004] The device disclosed in the patent can scrape and clean the dust on the surface of the instrument panel by means of a cleaning block, but the device cannot collect the cleaned dust. For vertically installed instruments and meters, after the staff removes the device, the dust will fall to the ground, and the staff will then need to clean the ground. This increases the staff's workload and is not conducive to efficient operation. In addition, when the device uses a sponge cleaning block to clean the dust on the surface of the instrument panel, some of the agglomerated dust is relatively stubborn and difficult to clean with the sponge, and the cleaning effect of the device is easily affected by this problem.
