Air delivery pipe of a humidifying apparatus

Abstract

An air delivery pipe of a humidifying apparatus comprises a hollow tube used for delivering warm and humid air and is wrapped by a heating device on its outer peripheries. The heating device includes a first connecting member and a second connecting member, where the first connecting member is disposed at one lateral side of the heating device while the second connecting member is disposed at another lateral side of the heating device for attaching the heating device to the outer peripheries of the tube. Air in the tube is heated by means of a heating element within the heating device.

1 . An air delivery pipe of a humidifying apparatus, comprising:
 a tube, for delivering warm and humid air; and   a heating device, including a first connecting member and a second connecting member, where the first connecting member is disposed at one lateral side of the heating device while the second connecting member is disposed at another lateral side of the heating device for attaching the heating device to the outer peripheries of the tube, and the heating device has a heating element therein for heating air inside the tube.   
   
   
       2 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1 , wherein the first connecting member and the second connecting member are combined to form a zipper. 
   
   
       3 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1 , wherein the first connecting member and the second connecting member are combined to form a fastening belt. 
   
   
       4 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1 , wherein the heating device is further provided with a transparent cover thereon for examining the delivered air in the tube. 
   
   
       5 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1 , wherein the heating element is disposed between a covering layer and a bottom layer. 
   
   
       6 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1 , wherein the heating element is an electro-thermal wire. 
   
   
       7 . The air delivery pipe of a humidifying apparatus as claimed in  claim 1  further includes a temperature controller, which is connected with the heating element.
