Breathing pipe assembly and snorkel equipment including said assembly

Abstract

A breathing pipe assembly is provided, which includes a mouthpiece and an inflexible breathing pipe. The mouthpiece is fixedly connected to the lower portion of the inflexible breathing pipe. The inflexible breathing pipe is defined with a central axis extending along a longitudinal direction thereof, and the mouthpiece is defined with a transverse line connecting a left side and a right side thereof. The transverse line forms an angle relative to the central axis, and the angle ranges between 3° and 70°.

What is claimed is: 
     
         1 . A breathing pipe assembly, comprising:
 a mouthpiece; and   an inflexible breathing pipe having an upper portion and a lower portion, wherein the upper portion provides air inlet and outlet, and the mouthpiece is fixedly connected to the lower portion;   characterized in that:   the inflexible breathing pipe is defined with a central axis extending along a longitudinal direction thereof, and the mouthpiece is defined with a transverse line connecting a left side and a right side thereof; and   the transverse line forms an angle relative to the central axis, and the angle ranges between 3° and 70°.   
     
     
         2 . The breathing pipe assembly of  claim 1 , wherein the angle ranges between 12° and 20°. 
     
     
         3 . The breathing pipe assembly of  claim 2 , wherein the angle is formed by the transverse line counterclockwise relative to the central axis. 
     
     
         4 . The breathing pipe assembly of  claim 3 , wherein the inflexible breathing pipe is adapted to be mounted in a left-high position, running over a left ear of a user. 
     
     
         5 . The breathing pipe assembly of  claim 3 , wherein the inflexible breathing pipe is adapted to be mounted in a right-low position, running underneath a right ear of a user. 
     
     
         6 . A snorkel equipment, comprising:
 a breathing pipe assembly, comprising:
 a mouthpiece; and 
 an inflexible breathing pipe having an upper portion and a lower portion, wherein the upper portion provides air inlet and outlet, and the mouthpiece is fixedly connected to the lower portion; and 
   a mask, comprising:
 a main body; and 
 a head strap fastened to the main body, thereby the main body being configured to water-tightly cover eyes and nose of a user, wherein the inflexible breathing pipe is adapted to be mounted in a left-high position, running over a left ear of the user, and is firmly fastened to a left end portion of the head strap; 
   characterized in that:
 the inflexible breathing pipe is defined with a central axis extending along a longitudinal direction thereof, and the mouthpiece is defined with a transverse line connecting a left side and a right side thereof; and 
   the transverse line forms an angle relative to the central axis, and the angle ranges between 3° and 70°.   
     
     
         7 . The snorkel equipment of  claim 6 , wherein the angle ranges between 12° and 20°. 
     
     
         8 . The snorkel equipment of  claim 7 , wherein the angle is formed by the transverse line counterclockwise relative to the central axis. 
     
     
         9 . A snorkel equipment, comprising:
 a breathing pipe assembly, comprising:
 a mouthpiece; and 
 an inflexible breathing pipe having an upper portion and a lower portion, wherein the upper portion provides air inlet and outlet, and the mouthpiece is fixedly connected to the lower portion; and 
   a mask, comprising:
 a main body; 
 a head strap fastened to the main body, thereby the body being configured to water-tightly cover eyes and nose of a user, wherein the inflexible breathing pipe is adapted to be mounted in a right-low position, running underneath a right ear of the user, and is firmly fastened to a mid portion of the head strap; 
   characterized in that:
 the inflexible breathing pipe is defined with a central axis extending along a longitudinal direction thereof, and the mouthpiece is defined with a transverse line connecting a left side and a right side thereof; and 
   the transverse line forms an angle relative to the central axis, and the angle ranges between 3° and 70°.   
     
     
         10 . The snorkel equipment of  claim 9 , wherein the angle ranges between 12° and 20°. 
     
     
         11 . The snorkel equipment of  claim 10 , wherein the angle is formed by the transverse line counterclockwise relative to the central axis.
