Abstract
A full-face mask, including a mask body, a breathing tube, an unfolded isolation support portion, at least one intake valve and at least one isolation plate, is provided. The mask body fits an user's face via a soft portion to form an interior space. The breathing tube is disposed on the mask body and is connecting with the interior space. The unfolded isolation support portion is disposed in the inner space and completely fits and covers the cheeks and the nose of the user to define an upper space and a lower space. At least one intake valve is disposed on the unfolded isolation support portion. A guide plate is disposed in a channel. Thus, the user could effectively breathe and exhale the air, and could isolate the face from the water leaking into the full mask to avoid danger.
