Hair dryer

Abstract

Provided are a diffuser and a hair dryer comprising same, wherein the diffuser comprises: a diffusing case which is formed in a cone shape of which the rear side is coupled to the head portion of the hair dryer to be attachable/detachable and which is widened in the forward direction thereof; a discharge cover which is coupled to the front portion of the diffusing case and has a plurality of discharge holes formed therein; and a bridge groove which is formed in the rear surface of the discharge cover and connects at least two discharge holes from among the plurality of discharge holes.

1 . A diffuser comprising:
 a cone-shaped diffusing case having a rear side removably coupled to a head part of a hair dryer, the diffusing case widening while extending in a forward direction;   a discharge cover coupled to a front of the diffusing case and provided with a plurality of discharge holes; and   a bridge groove formed in a rear surface of the discharge cover and connecting at least two of the discharge holes.   
     
     
         2 . The diffuser of  claim 1 , wherein the discharge holes comprise:
 a first discharge hole; and   a second discharge hole disposed further inside than the first discharge hole,   wherein the bridge groove extends from the second discharge hole to the first discharge hole in a radial direction from a center to a periphery.   
     
     
         3 . The diffuser of  claim 2 , wherein the second discharge hole is connected to a plurality of bridge grooves. 
     
     
         4 . The diffuser of  claim 2 , wherein the bridge groove is connected from one of second discharge holes included in the second discharge hole to one or more first discharge holes included in the first discharge hole. 
     
     
         5 . The diffuser of  claim 2 , further comprising:
 a third discharge hole disposed in a center of the second discharge hole and not connected to the bridge groove.   
     
     
         6 . The diffuser of  claim 1 , further comprising:
 a tubular hole protrusion extending forward from the discharge holes,   wherein an end of the hole protrusion comprises a curve.   
     
     
         7 . The diffuser of  claim 6 , wherein an inner diameter of the hole protrusion decreases as the hole protrusion extends forward. 
     
     
         8 . The diffuser of  claim 6 , further comprising:
 a massage protrusion protruding further forward than the hole protrusion.   
     
     
         9 . The diffuser of  claim 1 , wherein the diffusing case comprises:
 a ring-shaped gas inlet disposed in a rear surface of the diffusing case; and   a magnet disposed in a center of the ring-shaped gas inlet.   
     
     
         10 . A hair dryer comprising:
 a head part comprising a gas discharge portion allowing gas introduced from an outside to be discharged therethrough;   a handle extending from the head part; and   a diffuser removably coupled to the head part, wherein the diffuser allows the gas discharged from the gas discharge portion to be introduced thereinto and discharges the introduced gas to the outside,   wherein the diffuser comprises:   a cone-shaped diffusing case having a rear side removably coupled to the head part of the hair dryer, the diffusing case widening while extending in a forward direction;   a discharge cover coupled to a front of the diffusing case and provided with a plurality of discharge holes; and   a bridge groove formed in a rear surface of the discharge cover and connecting at least two of the discharge holes.   
     
     
         11 . The hair dryer of  claim 10 , wherein the diffusing case comprises:
 a ring-shaped gas inlet provided in a rear surface of the diffusing case, the gas inlet corresponding to the gas discharge portion; and   a first magnet disposed at a center of the ring-shaped gas inlet,   wherein the head part comprises a second magnet disposed at a center of the discharge portion.
