Hair dryer head for straightening hair

Abstract

A hair dryer head for straightening hair is provided, which includes a blowing shell and a hollow connection tube configured to connect with a blowing host. A hair clip cavity configured to pass through hair bundle is provided between a first blowing part and a second blowing part. A side of the first blowing part is provided with a first external blowing port, a side of the second blowing part is provided with a second external blowing port. Opposite surfaces of the first blowing part and second blowing part are respectively provided with a first internal blowing port and a second internal blowing port. A user only needs to clamp hair in the hair clip cavity and pull it down so as to start operating. Concentrated downward strong airflow provides a downward pulling force required for straightening hair, allowing the hair bundle to pass through the hair clip cavity.

       a hair clip cavity configured to pass through hair bundle is provided between the first blowing part and the second blowing part; one ends of the first blowing part and the second blowing part far away the hollow connection tube are provided with a hair guide opening that is configured to introduce the hair bundle and connect with the hair clip cavity;  
       a side of the first blowing part is provided with a first external blowing port, a side of the second blowing part is provided with a second external blowing port on the same side as the first external blowing port; 
       opposite sides of the first blowing part and the second blowing part are respectively provided with a first internal blowing port and a second internal blowing port;  
       an interior of the first blowing part is provided with a first air duct that is connected to the first external blowing port and the first internal blowing port; an interior of the second blowing part is provided with a second air duct that is connected to the second external blowing port and the second internal blowing port; air inlets of the first air duct and the second air duct are both facing the hollow connection tube. 
     
     
         2 . The hair dryer head according to  claim 1 , wherein blowing directions of the first internal blowing port and the second internal blowing port are respectively inclined to a plane where it is located; airflow directions blown out by the first internal blowing port, the second internal blowing port, the first external blowing port, and the second external blowing port are all in the same direction. 
     
     
         3 . The hair dryer head according to  claim 1 , wherein opposite surfaces of the first blowing part and the second blowing part are mutually parallel planes. 
     
     
         4 . The hair dryer head according to  claim 1 , wherein blowing directions of the first external blowing port and the second external blowing port are inwardly inclined at an angle in directions opposite to each other. 
     
     
         5 . The hair dryer head according to  claim 1 , wherein there are at least two first internal blowing ports and at least two first external blowing ports; the first air duct is provided with a first arc-shaped air guide plate having a number consistent with the number of first external blowing ports; there are at least two second internal blowing ports and at least two second external blowing ports, the second air duct is provided with a second arc-shaped air guide plate having a number consistent with the number of the second external blowing ports. 
     
     
         6 . The hair dryer head according to  claim 5 , wherein an end face of first air duct away from the second air duct is provided with a first arc-shaped boosting slope; a volume of the first air duct decreases from one end of the first arc-shaped boosting slope in a direction of the first external blowing port; 
       an end face of the second air duct away from the first air duct is provided with a second arc-shaped boosting slope; a volume of the second air duct decreases from one end of the second arc-shaped boosting slope in a direction of the second external blowing port. 
     
     
         7 . The hair dryer head according to  claim 1 , wherein an outer periphery of the blowing shell is fixedly installed with an outer shell,  
       an inner wall of one end of the outer shell near the hollow connection tube is provided with at least two positioning blocks; an end of the hollow connection tube near the outer shell is provided with a locking tooth configured to be clamped into the positioning block. 
     
     
         8 . The hair dryer head according to  claim 7 , wherein an inner wall of one end of the outer shell near the hollow connection tube is provided with at least two guide columns; an end of the hollow connection tube near the outer shell is provided with a guide groove configured to penetrate the guide columns, the hollow connection tube and the blowing shell are locked together by a screw. 
     
     
         9 . The hair dryer head according to  claim 1 , wherein the hair guide opening and the hair clip cavity are combined in a Y-shaped structure, a surface of the hair guide opening is a smooth arc-shaped structure.
