at this time, the insulating rod 20 is not subjected to centrifugal force any more, under the action of the elasticity of the compression spring 27, the insulating rod 20 slides into the limit groove 25 and is contacted with the metal sheet 28, the metal sheet 28 transfers charges to the ground or other low-potential objects through the lead 23 and the conductive block 22, static electricity at the insulating rod 20 is eliminated, dust is not adsorbed any more, meanwhile, the compression spring 27 and the elastic sheet 26 continuously vibrate, so that the insulating rod 20 collides with the metal sheet 28 for many times, and dust on the insulating rod 20 is promoted to shake off into the dust collecting groove 21;
when the temperature in the housing 1 rises again (the sensor 11 detects that the ambient humidity is smaller), the axial fan 30 is turned on again, the resistance fan blade 18 drives the insulating disc 17 and the insulating rod 20 to rotate, and the insulating rod 20 collects the entered dust again in the same process as the above, so that each position in the housing 1 is in a clean state, and the probability of occurrence of short circuit, breakdown and other problems caused by accumulation of dust is reduced.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
