摘要： The present technology relates to open respirator devices having sensors for measuring breath biometrics. For example, a respirator device (100) can include a mask component (102) that fits at least partially over a user's face and forms a gap (112) between a periphery of the mask component and the user's face, thereby forming a breathing chamber (108) between the mask portion and the user's face. A fan unit can provide air from the external environment to the breathing chamber for the user to inhale. In some embodiments, the air may be filtered before entering the breathing chamber and the fans may provide a positive pressure seal between across the gap. One or more sensors can be coupled to the mask component for measuring one or more metrics associated with the user's breath.

摘要： There is provided a mask clip assembly for use with a face mask. The assembly includes a housing having inner and outer housing shells. The housing has open and closed positions. In the closed position the inner and outer housing shells are engaged with each other and form a cavity between the inner and outer housing shells. In the open position the inner and outer housing shells are separated and disposed away from each other in comparison to the closed position, the housing being sized and configured to engage the face mask with a portion of a mask periphery disposed in the cavity with the housing in the closed position. The assembly includes an air filter and intake and exhaust ports. The assembly includes an intake tube attached to the housing and in fluid communication between the housing and the intake port. The intake tube is positionable adjacent an inner face mask side with the housing in the closed position with a portion of the mask periphery disposed in the cavity. The assembly includes a one-way valve that is configured to prevent fluidic flow from the exhaust port through the housing to the intake tube. The assembly includes a fluidic path extending into the intake port through the intake tube, the air filter, the cavity and the one-way valve and out of the exhaust port with the housing in the closed position.

摘要： A full-face diving mask includes a mask and a breathing tube. The mask includes an outer frame, a lens housing and a fitting mask. The fitting mask includes a partition plate. The partition plate and the inner surface of the lens housing define an observation chamber on the top and a breathing chamber below. The partition plate includes at least one air intake port to allow inhaled air to be guided and circulated through at least one air intake passageway from the observation chamber toward the breathing chamber. The breathing chamber is further provided with an air compartment partition plate connected to the partition plate to define an air discharge compartment. The air compartment partition plate is provided with at least one air discharge port to allow exhaled air to be guided through at least one air discharge passageway from the air discharge compartment and discharged along the breathing tube.
