Direct-blowing neck-hanging fan

Abstract

A direct-blowing neck-hanging fan comprises a device host, wherein the device host comprises a neck-hanging part, and a neck-hanging cavity is formed in the middle to be hanged on the neck; air outlet heads, which are detachably installed at both ends of the neck-hanging part; air outlet components, which are provided inside the air outlet heads. The invention adopts the direct-blowing method to increase the blowing volume, so that the air output rate is higher, and solves the problem of air volume loss caused by extrusion of the air in the prior art, so that the air can be more concentrated; in addition, the combination of the air outlet head and the neck-hanging part makes the position of the air outlet closer to the human body.

1 . A direct-blowing neck-hanging fan, comprising a device host, wherein the device host comprises:
 a neck-hanging part, and a neck-hanging cavity is formed in the middle to be hanged on the neck;   air outlet heads ( 5 ), which are detachably installed at both ends of the neck-hanging part;   taking the side of the neck-hanging part in contact with the neck of the human body as the reference plane, the air outlet head ( 5 ) protrudes outward from the reference plane ( 10 ), and forms an air outlet surface on the protruding surface close to the reference plane side of the neck-hanging part; the air outlet surface towards the neck of the human body;   air outlet components, which are provided inside the air outlet heads ( 5 ); the air outlet end of the air outlet component corresponds to the air outlet surface, and an air outlet ( 4 ) is formed on the air outlet surface thereof; the airflow discharged by the air outlet component is directly discharged through the air outlet ( 4 ) and blows to the human body at a fixed point.   
     
     
         2 . The direct-blowing neck-hanging fan of  claim 1 , wherein the blowing angle between the air outlet ( 4 ) and the horizontal plane ranges from 15 degrees to 60 degrees. 
     
     
         3 . The direct-blowing neck-hanging fan of  claim 1 , wherein the air outlet component comprises a motor ( 9 ), blades ( 13 ), and an air outlet box ( 12 );
 the air outlet box ( 12 ) is provided with an accommodating cavity inside, and the motor ( 9 ) and blades ( 13 ) are installed in the accommodating cavity; the position of the air outlet box ( 12 ) facing the air outlet forms an air outlet opening ( 11 ), and the airflow generated by the blades is discharged through the air outlet opening ( 11 ); an arc-shaped diversion cavity is formed inside the accommodation cavity;   an air inlet ( 6 ) is formed on the side of the air outlet head ( 5 ) facing the air outlet box, and the air outlet box ( 12 ) is opened at a position corresponding to the air inlet ( 6 ).   
     
     
         4 . The direct-blowing neck-hanging fan of  claim 1 , wherein one side of the air outlet head ( 5 ) extending away from the air outlet head forms a neck-hanging connecting section; a butt joint pipe ( 3 ) is installed between the neck-hanging connecting sections formed at both ends to form the neck-hanging part. 
     
     
         5 . The direct-blowing neck-hanging fan of  claim 4 , wherein the neck-hanging connecting section comprises a first neck-hanging connecting section ( 2 ) and a second neck-hanging connecting section ( 3 ); the first neck-hanging connecting section ( 2 ) is spliced by a first connecting section bottom shell ( 22 ) and a first connecting section surface shell ( 21 ) to form a first arc-shaped tubular member, and the second neck-hanging connecting section ( 3 ) is spliced by a second connecting section bottom shell ( 32 ) and a second connecting section surface shell ( 31 ) to form a second arc-shaped tubular member; the butt joint pipe ( 3 ) has the same radian as the first arc-shaped tubular member and the second arc-shaped tubular member, and the three form a U-shaped neck-hanging part. 
     
     
         6 . The direct-blowing neck-hanging fan of  claim 5 , wherein the first neck-hanging connecting section ( 2 ) and the second neck-hanging connecting section ( 3 ) are both provided with a battery ( 7 ); a main control board ( 15 ) is provided in the first neck-hanging connecting section ( 2 ) or in the second neck-hanging connecting section ( 3 ), and the main control board ( 15 ) is provided with control buttons; the batteries ( 7 ) are all connected to the main control board ( 15 ) and charged through the charging interface provided on the main control board ( 15 ). 
     
     
         7 . The direct-blowing neck-hanging fan of  claim 1 , wherein the air outlet surface of the air outlet head ( 5 ) is an inclined surface, and the air outlet surface is inclined toward the side away from the air outlet head.
