The utility model relates to the maintenance field of generators and in particular relates to a carbon powder collection box and a brush generator using the collector box. The carbon powder collection box comprises a box body and a filter screen which is arranged in the box body; an air inlet and an air outlet are formed in the box body; the filter screen is a basket-shaped filter screen. The filter screen of the carbon powder collection box is the basket-shaped filter screen, so that the filtering area of the filter screen can be greatly increased on the promise that the volume of the box body is not changed, thus the process for blocking the filter screen is slowed down, the normal work cycle of the carbon powder collection box is prolonged, and the maintenance cost of the carbon powder collection box is reduced. Due to the adoption of the carbon powder collection box, the problems of short maintenance cycle and high maintenance cost of the current carbon powder collection box are solved.
