A device that blows air

Abstract

The purpose of this invention is to provide a device that blows air by fanning, without generating motor noise by not using a motor. [Solution] An electromagnet and a permanent magnet are placed in close proximity. When an electric current is applied, the electromagnet generates a magnetic force that repels the permanent magnet, causing it to move away from the permanent magnet. When the electric current is cut off, the electromagnet loses its magnetic force and is drawn towards the permanent magnet by its magnetic force. By repeatedly applying and cutting the electric current, this force is converted into a reciprocating motion, and this reciprocating motion is used to create a fan that blows air.

Summary of the Invention

Problems to be Solved by the Invention

[0008] [Figure 1] This is an overall diagram of the fanning device that blows air according to the present invention. [Figure 2] This is a horizontal cross-sectional view showing the structure of the power unit 1. [Figure 3] This is a vertical cross-sectional view showing the structure of the power unit 1. [Figure 4] This figure shows the movement when power is applied to Figure 2. [Figure 5] Figure 4 shows the behavior when the power is cut off. [Figure 6] This is an overall view showing the weights positioned and the fanning direction directed upwards. [Modes for carrying out the invention]

[0009] The goal of generating airflow without using a motor was achieved by combining a permanent magnet that constantly possesses magnetic force with an electromagnet that generates magnetic force when power is applied. [Examples]

[0010] Figure 1 is an overall diagram of the present invention, in which the power unit 1 moves back and forth in an arc around the power support unit 2 by alternately switching the power on and off. This causes the fan unit 3 to perform a fanning motion.

[0011] Figure 2 is a horizontal cross-sectional view showing the structure of the power unit 1, and Figure 3 is a vertical cross-sectional view showing the structure of the power unit 1. The electromagnet 5 is fixed to the power support unit 2, and the left side 10 and right side 11 of the electromagnet represent the ends of the electromagnet 5. A permanent magnet 8 with the inner pole facing north and a permanent magnet 9 with the inner pole facing south are fixed to the outer frame 6 of the power unit and are arranged to rotate around the bearing 7.

[0012] Figure 4 shows the movement of the outer frame 6 of the power unit when energized. When energized, the permanent magnet 8 with the north pole on the inside tries to move away from the left side 10 of the electromagnet which has the north pole due to the energization. Similarly, the permanent magnet 9 with the south pole on the inside tries to move away from the right side 11 of the electromagnet which has the south pole due to the energization.

[0013] Figure 5 shows the movement of the outer frame 6 of the power unit when power is cut off from the state of Figure 4. When power is cut off from the state of Figure 4, the permanent magnet 8 with the inner side being the N pole tries to approach the left side portion 10 of the electromagnet whose magnetic force has disappeared due to power cut-off by its own magnetic force. Similarly, the permanent magnet 9 with the inner side being the S pole tries to approach the right side portion 11 of the electromagnet whose magnetic force has disappeared due to power cut-off by its own magnetic force. By repeating power-on and power-off in this way, the outer frame 6 of the power unit makes a reciprocating motion around the bearing 7, and the fan part 3 performs a fanning operation.

Embodiment

[0014] Figure 6 shows an embodiment when the fanning direction is upward. In Figure 1, due to the weight of the fan, the fan is held downward and the fanning operation of the fan is also performed downward. However, in Figure 6, by disposing a weight 12 in the power unit 1, the direction of the fan is reversed, and thereby the fan is held upward and the fanning operation of the fan can also be upward.

Claims

1. This device uses an electromagnet and a permanent magnet placed close together. When power is applied, the electromagnet generates a magnetic force that repels the permanent magnet, causing it to move away from the permanent magnet. When the power is cut off, the electromagnet loses its magnetic force and is drawn towards the permanent magnet by its magnetic force. By repeatedly applying and cutting the power, this force is converted into a reciprocating motion, which is then used to create a fan that blows air.

2. A wind-distributing device according to claim 1, characterized in that the direction of fanning is reversed by arranging a weight on the opposite side of the direction of fanning.
