Claims

[Claims for Utility Model Registration] (1) An electric fan characterized by having at least four rotating fans placed back to back so that each fan generates wind in directions opposite to each other. (2) The electric fan according to claim 1, wherein the blades of the rotating fan are formed so that the tendency of axial flow is weak at the center of the shaft and the tendency of centrifugal flow is strong at the outer circumference. (3) The electric fan according to claim 1 or 2 of the utility model registration claim in which the distance between the back to back is variable. (4) Wind is taken into the ball-shaped blade, and small blades are installed inside the blade, and the blade on the outer periphery rotates in the right direction, and the wind is absorbed by the force of the small blade provided on the outer periphery, which has irregularities on the outer wall surface. Therefore, the small blades installed in the ball-shaped blades receive the wind taken in from the ventilation hole, rotate counterclockwise, and send out gentle wind to the front. The electric fan described in item 3. (5) When the blade is attracted by the force of an electromagnet and rotates, and one of the left and right blades is stopped, the force of electricity flowing in the opposite direction causes the rotating shaft to slide left and right by the repulsive force of the electromagnet, stopping the two blades. Paragraph 1, Paragraph 2, or Paragraph 3 of Claims for Utility Model Registration
The electric fan described in paragraph 4 or paragraph 4. (6) The electric fan according to claim 1, 2, 3, 4, or 5, which is a blade stopper that is formed by the force of a magnet and a spring protrusion and can fix the blades.
