Full-face mask

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.

1 . A full-face mask being wearable on a user's face, comprising:
 a mask body, comprising a lens portion and a soft portion connected to each other, the soft portion fitting the face of the user, and the mask body forming an interior space;   a breathing tube, being arranged on the mask body and connected with the interior space;   an unfolded isolation support portion, being arranged in the interior space so that the interior space defines an upper space and a lower space, the lower space being connected with the breathing tube; and   at least one intake valve, being arranged on the unfolded isolation support portion;   wherein a channel is defined at the junction of the lens portion and the soft portion, and the channel comprises a guide plate to prevent the circulation of gas flowing from a lower end of the channel to the breathing tube.   
     
     
         2 . The full-face mask of  claim 1 , wherein a channel is defined at the junction of the lens portion and the soft portion, and the channel comprises a guide plate to prevent the circulation of gas flowing from a lower end of the channel to the breathing tube. 
     
     
         3 . The full-face mask of  claim 1 , further comprising a first isolation plate disposed in the lower space so that the lower space defines a proximal space and a distal space, wherein the proximal space is close to a nose of the user. 
     
     
         4 . The full-face mask of  claim 3 , wherein the first isolation plate further comprises a one-way valve for discharging exhaust gas exhaled by the user. 
     
     
         5 . The full-face mask of  claim 1 , wherein the lens portion further comprises a diversion port connected with the distal space. 
     
     
         6 . The full-face mask of  claim 1 , wherein the soft portion further comprises a stopper piece which covers the diversion port.
