Description

Fan fan

The present invention relates to a fan fan, and more particularly, fan fan that can provide a fan wind close to the natural wind to users who do not like the vortex wind generated by the operation of the rotary blades mounted on the motor shaft of the general fan It is about.

In general, a fan is a device that generates wind by rotating the rotor blades mounted on the rotating shaft of the motor, the wind generated from the fan rotor blades are vortex wind, so it feels warm, and if the fan is operated for a long time, the motor located behind the rotor blades Is overheated, the heat is discharged to the front through the rotary wing as it is disadvantageous to the user.

Users who do not like the vortex wind generated by the rotary blades of the fan are not using the fan itself, but use natural fan by using a fan of various shapes separately provided.

However, the fan of various shapes causes the wind by swinging by the force of the user, and when a certain time is used, the fan is moved by the user's hand, wrist, and arm movements rather than feeling cool by the wind generated by the fan. There was a drawback that the energy consumption is more and more warm.

Therefore, the present invention has been created to solve the above problems, the fan that can provide a fan wind, such as natural wind instead of vortex wind generated by the operation of the rotary blades mounted on the motor rotating shaft of the existing fan The purpose is to provide a fan.

Fan fan according to the present invention for achieving the above object, in the fan fan provided with a space between the upper case and the lower case, the motor, the reduction roller is rotated in engagement with the rotating shaft of the motor, the reduction roller is connected Bevel gear portion is rotated integrally with the bevel gear portion, at least one silicon rubber is mounted on the outer circumferential surface of the cylindrical body and rotated in opposite directions, rotated in engagement with the silicon rubber of the upper and lower rotors and the silicon Fan rotating roller with upper and lower outer circumferential surfaces engaging with the rubber, fan rotating shaft inserted into and fixed to the central hole of the upper surface of the fan rotating roller, fan fixing portion connected to the fan rotating shaft, fan top and bottom of the fan fixed to the fan fixing shaft. An angle adjusting unit for adjusting the left and right angles, and is installed on the upper surface of the upper case Characterized in that it comprises a time setting and the speed control operation.

When an external force is applied between the fan rotating shaft and the angle adjusting unit of the present invention, a rotating safety part that generates sound while the engaged upper and lower teeth are separated from each other is further installed, and the rotating safety part has an upper tooth part and a lower part. The teeth are configured to be engaged with each other, and the lower side is provided with an elastic spring for pushing the lower teeth upwards, and the upper cover is provided with a rotary cover for fixing by pushing the upper teeth downward.
