[0003] The existing filter box of the electric respirator directly fills activated carbon particles in the box body, one side of the box body is an air inlet face, and the other side is an air outlet face. However, since there are gaps between the activated carbon particles and the particles, with the vibration of the product, the gaps between the activated carbon particles and the particles gradually become smaller. Under the action of the gravity of the activated carbon particles, a vacuum area is easily formed at the top of the box body. Since there is no activated carbon in the vacuum area, the breathing resistance of the vacuum area is the lowest, which causes contaminated gas to enter the breathing mask through the vacuum area, and seriously affects the filtering effect of the filter box. SUMMARY
