Distribution box with dustproof and heat dissipation functions

The utility model belongs to the technical field of distribution boxes, and particularly discloses a distribution box with dustproof and heat dissipation functions, which comprises a placement plate, pulleys are fixedly connected to the bottom surface of the placement plate, and a cylinder is fixedly inserted into the top surface of the placement plate. Compared with a common distribution box in the prior art, the distribution box with the dustproof and heat dissipation functions sucks external air into the box body through the lower side fan, and discharges heat in the box body through the through holes through the upper side fan, so that the heat dissipation speed of the device is accelerated, and meanwhile, the fans drive the cams to rotate to promote the T-shaped scrapers to move, so that the heat dissipation efficiency of the device is improved. The filter screen on the lower side is cleaned through the T-shaped scraping plate, more sundries are prevented from being accumulated on the filter screen, the
