Description

TECHNICAL FIELD

The present disclosure relates to a neckband fan. More particularly, the present disclosure relates to a neckband fan for easily adjusting a direction of wind and minimizing discomfort due to heat generation.

BACKGROUND

A portable fan is easy to carry since it is manufactured in a small size, but it may cause inconvenience that must be held in the hand. For example, when a user is jogging or riding a bicycle, it may be difficult for the user to use the portable fan.

In order to solve such inconvenience, a portable fan (neckband fan) that can be worn on the user's neck has been developed. In an existing neckband fan, a battery is mounted on the part worn on his/her neck and provides heat to his/her neck, and thus he/her may rather feel uncomfortable. In addition, since the part of the neckband fan worn on his/her neck has a fixed shape, inconvenience of use and storage may occur when the neckband fan is not worn on his/her neck.

The electric power provided through the port 1730 may be delivered to the battery 1600 accommodated in the second head 102 through the controller 1710.

The battery 1600 accommodated in the first head 101 may be charged by receiving electric power through the electric wire. The electric wire connected to the battery 1600 accommodated in the first head 101 may pass through the bracket wiring tube 1224 of the first head 101 and may lead to the core coupling portion 1382 of the first head 101. The electric wire leading to the core coupling portion 1382 of the first head 101 may pass through the inside of the core 220 and lead to the second head 102. The electric wire leading to the second head 102 may pass through the core coupling portion 1382 and the bracket wiring tube 1224 of the second head 102 and may be connected to the controller 1710.

The push input provided through the input lever 1458 may be transmitted to the input unit 1720. The input unit 1720 may transmit the push input to the controller 1710. The controller 1710 may generate a signal in response to the obtained input. For example, the signal generated by the controller 1710 may include information on an output of the motor 1510. The output of the motor 1510 may be divided into “stop” and “operation”. The operation of the motor 1510 may include, for example, “fast” and “slow”. That is, in response to the signal generated by the controller 1710, the motor 1510 may operate or stop, and the motor 1510 may rotate relatively quickly or slowly.

A path through which the signals (and electric power) are transmitted from the controller 1710 accommodated in the second head 102 to the motor 1510 accommodated in the first head 101 may be formed. For example, the electric wire connected to the controller 1710 accommodated in the second head 102 may sequentially pass through the bracket wiring tube 1224 and the core coupling portion 1382 of the second head 102 and may enter the inside of the core 220. The electric wire entering the inside of the core 220 may pass through the inside of the core 220 and may enter the core coupling portion 1382 of the first head 101. The electric wire entering the core coupling portion 1382 of the first head 101 may pass through the first bracket inner plate opening 1115 of the first head 101 and may be connected to the motor of the first head 101.

With reference to FIGS. 1 to 25, a structure, in which the controller 1710 accommodated in the second head 102 controls not only the motor 1510 accommodated in the second head 102 but also the motor 1510 accommodated in the first head 101, has been introduced. However, the present disclosure is not limited thereto. For example, a controller 1710 that is substantially the same as the controller 1710 accommodated in the second head 102 may also be accommodated in the first head 101. In this case, the controller 1710 accommodated in the first head 101 may control the motor 1510 accommodated in the first head 101, and the controller 1710 accommodated in the second head 102 may control the motor 1510 accommodated in the second head 102.

A process in which wind is generated by rotating the motor 1510 inside the head 100 is described. When the motor 1510 rotates, the fan frame 1521 may rotate. When the fan frame 1521 rotates, the blade 1525 may rotate. When the blade 1525 rotates, air may be accelerated by the blade 1525 in the radial direction.
