Face Mask, Visor, Or Like Face-covering Means Hinged To Scalp Covering Means Patents (Class 128/201.24)
  • Patent number: 10610708
    Abstract: An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub. If the personal communication hub receives a signal indicating the presence of a hazard, and if the visor is in an open position, an alert is generated.

  • 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.
