Full-face mask

Abstract

A full-face mask including a mask body, a breathing tube, an isolation support portion, and a first partition is provided. The mask body includes a lens portion and a soft portion, the soft portion fits a user's face to form an inner space. The breathing tube is disposed above the mask body and is connecting with the inner space. The isolation support portion is disposed in the inner space to define an upper space and a lower space which are connected with each other. A first partition is disposed in the lower space and includes an intake valve. The lower space is defined with a proximal space and a distal space. When the user inhales, the clean air passes through the intake valve into the proximal space. Thus, the user could effectively breathe, exhale and/or isolated from leakage water to avoid danger.

What is claimed is: 
     
         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 is configured to fit the user's face to form an inner space thereof;   a breathing tube, being disposed above the mask body and connected with the inner space for the user to inhale clean air;   an isolation support portion, being disposed in the inner space to define an upper space and a lower space thereof, wherein the upper space is connected with the lower space; and   a first partition, being disposed in the lower space to define a proximal space and a distal space thereof, further comprising an intake valve, whereby the clean air enters the proximal space through the intake valve when the user inhales the clean air;   wherein the breathing tube is configured to connect with the proximal space of the lower space, whereby the dirty air exhaled from the user leave the proximal space through the breathing tube.   
     
     
         2 . The full-face mask of  claim 1 , wherein the first partition is shaped to allow the intake valve to be close to and aimed at the user's nostril. 
     
     
         3 . The full-face mask of  claim 1 , wherein the intake valve is a constantly open intake valve. 
     
     
         4 . The full-face mask of  claim 1 , wherein the first partition further comprises an exhaust valve which is disposed below the intake valve to further discharge the dirty air exhaled from the user. 
     
     
         5 . The full-face mask of  claim 1 , further comprising a second partition which is disposed in the distal space to define a guide space and a temporary storage space of the distal space. 
     
     
         6 . The full-face mask of  claim 5 , wherein the lens portion further comprises a guide opening which is connected with the temporary storage space. 
     
     
         7 . The full-face mask of  claim 5 , further comprising at least one one-way valve which is disposed in the temporary storage space to discharge water or the dirty air exhaled from the user. 
     
     
         8 . The full-face mask of  claim 1 , further comprising a channel and a splitter, wherein the channel is formed where the lens portion connects to the soft portion, and the splitter is disposed in the channel to prevent the circulation of air flowing from a lower end of the channel to the breathing tube.
