Neckband fan

Abstract

A neckband fan is provided. The neckband fan includes a band that forms an elongated shape from a first end to a second end and is bent or unfolded, and a head coupled to both ends of the band. The head includes a first housing coupled to the band and forming a space therein, a bracket accommodated in the first housing and coupled to the first housing, a second housing coupled to the first housing and the bracket, and a wind unit accommodated in the bracket and configured to generate a wind. The bracket is disposed between the first housing and the second housing. The wind passes through a blowing discharge opening formed in the bracket, passes through a housing blowing discharge portion formed in the housing, and is discharged to an outside of the head.

 a bracket, accommodated in the first housing and coupled to the first housing; 
 a second housing, coupled to the first housing and the bracket; and 
 a wind unit accommodated in the bracket and configured to generate a wind, 
   wherein the bracket is disposed between the first housing and the second housing,   wherein the wind generated by the wind unit, passes through a blowing discharge opening formed in the bracket, passes through a housing blowing discharge portion formed in the housing, and is discharged to an outside of the head.   
     
     
         2 . The neckband fan of  claim 1 , wherein the bracket includes:
 a first bracket on which the wind unit is mounted; and   a second bracket coupled to the first bracket and facing the second housing;   
     
     
         3 . The neckband fan of  claim 2 , wherein the wind unit includes:
 a motor mounted on the first bracket and configured to generate a rotational force; and   a fan module connected to the motor and configured to receive the rotational force and rotate.   
     
     
         4 . The neckband fan of  claim 3 , wherein the first bracket includes:
 a first bracket inner plate on which the motor is mounted;   a first bracket outer plate positioned outside the first bracket inner plate and having a shape surrounding the first bracket inner plate, the first bracket outer plate being spaced apart from the first bracket inner plate;   a first bracket bridge connecting the first bracket inner plate to the first bracket outer plate and positioned between the first bracket inner plate and the first bracket outer plate; and   a first bracket opening defined by the first bracket inner plate, the first bracket outer plate, and the first bracket bridge,   wherein when the motor rotates, an air positioned outside the bracket reaches the fan module through the first bracket opening.   
     
     
         5 . The neckband fan of  claim 4 , wherein the first bracket further includes:
 a first bracket wall having a shape extending toward the second bracket along the first bracket outer plate; and   a first bracket coupling portion formed on the first bracket wall and coupled to the second bracket.   
     
     
         6 . The neckband fan of  claim 4 , wherein the second bracket includes:
 a second bracket inner plate facing the motor;   a second bracket outer plate positioned outside the second bracket inner plate and having a shape surrounding the second bracket inner plate, the second bracket outer plate being spaced apart from the second bracket inner plate;   a second bracket bridge connecting the second bracket inner plate to the second bracket outer plate and positioned between the second bracket inner plate and the second bracket outer plate; and   a second bracket opening defined by the second bracket inner plate, the second bracket outer plate, and the second bracket bridge,   wherein when the motor rotates, the air positioned outside the bracket reaches the fan module through the first bracket opening and the second bracket opening.   
     
     
         7 . The neckband fan of  claim 2 , wherein the second bracket includes:
 a second bracket outer plate positioned opposite the first bracket with the wind unit interposed therebetween; and   a first rib coupler formed on the second bracket outer plate,   wherein the first housing includes a first housing rib coupled to the first rib coupler.   
     
     
         8 . The neckband fan of  claim 7 , wherein the second bracket includes a second rib coupler formed on the second bracket outer plate,
 wherein the second housing includes a second housing rib coupled to the second rib coupler,   wherein the second housing rib and the first housing rib are screw-coupled to each other.   
     
     
         9 . The neckband fan of  claim 1 , wherein the first housing includes a housing band coupling portion in which an end of the band is accommodated and coupled. 
     
     
         10 . The neckband fan of  claim 9 , wherein the band includes:
 a skin having an elongated shape from the first end to the second end and forming an empty space therein; and   a core having an elongated shape from the first end to the second end and surrounded by the skin, the core being bent or unfolded.   
     
     
         11 . The neckband fan of  claim 10 , wherein the housing band coupling portion includes:
 a skin coupling portion in which an end of the skin is accommodated and coupled; and   a core coupling portion in which an end of the core is accommodated and coupled.   
     
     
         12 . The neckband fan of  claim 11 , wherein the skin coupling portion has an elongated shape along a perimeter of the first housing. 
     
     
         13 . The neckband fan of  claim 11 , wherein the core coupling portion is accommodated in the skin coupling portion. 
     
     
         14 . The neckband fan of  claim 1 , wherein the head includes:
 a battery accommodated in the second housing; and   a controller accommodated in the second housing and connected to the battery and the wind unit,   wherein the controller is configured to receive an electric power from the battery and deliver the electric power to the wind unit.   
     
     
         15 . The neckband fan of  claim 1 , wherein the head includes:
