  • Patent number: 10293194
    Abstract: A mask includes a cover body, a first fan, a second fan and an air filter. The cover body has an air inlet and an air outlet penetrating through the cover body. The first fan is disposed on the cover body and matches the air inlet. The second fan is disposed on the cover body and matches the air outlet. The air filter is disposed on the cover body and partially overlaps the air inlet. The first fan drives an air-flow to rapidly flow from the atmosphere into the mask through the air inlet and the air filter. The air filter removes the particulates and the harmful substances in the air-flow. The second fan drives the respiratory gas to rapidly flow from the mask to the atmosphere through the air outlet. Therefore, the user is able to breathe comfortably with non-particulate and clean air.
