The invention belongs to the technical field of information processing equipment, and discloses an information processing device of electronic equipment, and the information processing device comprises an information processor body, the information processor body comprises a case and a touch screen, and an electric appliance element is arranged in the case. According to the scheme, during use, a driving motor is powered on to operate to drive a rotating shaft to rotate, then a first cooling fan is driven to rotate, the electric appliance element in the case is cooled, meanwhile, along with rotation of the rotating shaft, three first belt wheels are driven to rotate, and through mutual cooperation of three belts, auxiliary heat dissipation pieces on the left side, the right side and the rear side of the electric appliance element are driven to work at the same time, so that the heat dissipation effect is improved, dust on a first heat dissipation net and a second heat dissipation net can be effectively removed through a dust removal assembly in the using process, the first heat dissipation net and the second heat dissipation net are prevented from being blocked, the heat dissipation effect is improved, and the dust is collected in a dust collection box, therefore, centralized processing is facilitated.
