Problems solved by technology

The above-mentioned swing structure is not flexible enough in use, sometimes only one or two people blow the fan, but the swing angle of the fan is too large, most of the time it is blowing in a place where there is no one, wasting the wind power

Embodiment 1

[0016] Such as figure 1 , 2 As shown, the fan head rotation angle adjustment mechanism in this embodiment includes a fan bracket 1 and a fan head 3 mounted on the fan bracket 1 through a rotating shaft 2 (the rotating shaft 2 can rotate on the fan bracket 1), the key point is that the fan bracket 1 A motor 13 is fixed on the top of the motor, and the motor shaft of the motor 13 drives the rotating shaft 2 and the fan head 3 on the rotating shaft 2 to rotate through a gear pair; a horizontal disc 4 is installed on the rotating shaft 2, and the bottom surface of the disc 4 There is an arc-shaped resistance sheet 5, a circular first metal sheet 6 and a circular second metal sheet 7. The resistance sheet 5 and the metal sheet are all centered on the rotating shaft 2, and the resistance sheet 5 is located on the first metal sheet. between the sheet 6 and the second metal sheet 7; one end of the resistor sheet 5 is electrically connected to the first metal sheet 6, and the other en...

Abstract

The invention provides a fan head rotation angle adjusting mechanism capable of adjusting the rotation angle of a fan head. The top end of a fan support is provided with a motor driving the fan head to rotate. A horizontal disk is installed on the rotating shaft of the fan head. The bottom face of the disk is provided with an arc resistor sheet, a round first metal sheet and a round second metal sheet. The rotating shaft is used as the circle centers of the resistance sheet and the metal sheet. The two ends of the resistor sheet are electrically connected with the first metal sheet and the second metal sheet correspondingly. The fan support is provided with a first terminal, a second terminal and a third terminal. The top end of the first terminal is in contact with the first metal sheet.The top end of the second terminal is in contact with the second metal sheet. The top end of the third terminal is in contact with the resistor sheet. The first terminal is connected with a power source. The second terminal is grounded. The adjusting mechanism further comprises a controller provided with an angle input unit. The controller is connected with the third terminal. The controller is connected with the motor through a forward-opposite switch.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a fan head rotation angle adjustment mechanism. Background technique [0002] The fan head of a traditional floor fan can swing left and right. The swing structure is a set of worm gear system and connecting piece. The worm gear system drives the swinging rotation. The angle range is determined by the length of the connecting piece and the eccentric radius. The eccentric radius cannot be changed at will, so the angle cannot be adjusted. Above-mentioned oscillating structure is not flexible enough in use, and sometimes only one or two people blow the fan, but the oscillating angle of fan is too large, and most of the time it is blowing where no one is there, wasting the wind power. Contents of the invention [0003] The object of the present invention is to provide a fan head rotation angle adjustment mechanism, which can easily adjust the fan head rotation angle to me...
