DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0026] It should be noted that when a component is referred to as "fixed to" or "provided on" another component, it can be directly or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component. The terms "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position shown in the drawings, and are only for convenience of description, and cannot be understood as a limitation on the technical solutions. The terms "first", "second" are only for the purpose of convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "multiple" is two or more, and the meaning of "several" is any number including one, unless otherwise explicitly specified.

[0027] Please refer to the accompanying Figures 1-5 The utility model discloses a kind of electric swing fans, including: rack 6, the mounting plate 61 of rack 6 is fixedly installed with drive device 11, drive device 11 is preferably motor, drive device 11 is connected swing piece 3 by adapter 8, swing piece 3 is installed with fan blade 4, in optional embodiment, swing piece 3 is also installed with balance bar 5;Mounting plate 61 is fixedly provided with arc-shaped stop block 15, and the two ends of arc-shaped stop block 15 are first limit end 151, second limit end 152 respectively;Adapter 8 is provided with arc-shaped swing block, and the two ends of arc-shaped swing block are first reset end 81, second reset end 82 respectively.

[0028] When the electric oscillating fan 11 is operating normally, the drive unit 11 drives the arc-shaped oscillating block of the adapter 8 to oscillate back and forth between the first limiting end 151 and the second limiting end 152. The first reset end 81 does not contact the first limiting end 151, and the second reset end 82 does not contact the second limiting end 152. The fan blades 4 are fitted with a balance bar 5 to balance the force on the drive unit 11. Through this structure, efficient oscillation of the fan is achieved. It should be noted that when the electric oscillating fan malfunctions, under the drive of the drive unit 11, the first reset end 81 contacts the first limiting end 151, or the second reset end 82 contacts the second limiting end 152, thus resetting the fan blades. This is the initial reset of the drive unit 11, allowing the drive unit 11 to oscillate within a defined range.

[0029] Specifically, the output shaft of the drive unit 11 is fixedly connected to the adapter 8; the adapter 8 is provided with a mounting hole 83, which is fixedly connected to the swinging member 3 by screws 10. The frame 6 is mounted on the base 1, and a housing 2 is provided on the base 1, covering the frame 6. The swinging member 3 is fixedly connected to the inner ring of the bearing 9, and the bearing 9 is fixedly mounted on the housing 2, reducing the resistance encountered by the fan blade 4 during swinging.

[0030] Furthermore, the bottom of the base 1 is provided with a plurality of suction cups 7 evenly arranged, which can attach the oscillating fan to the tabletop for easy use.

[0031] In this embodiment, the oscillating component 3 is provided with a first connecting end 31 and a second connecting end 32, and the outer surfaces of the first connecting end 31 and the second connecting end 32 are respectively provided with threads. A silicone sleeve 12 is installed inside the oscillating component 3, extending from the first connecting end 31 to the second connecting end 32. The end cap of the silicone sleeve 12 overlaps the outer surface of the first connecting end 31; the end cap 13 is threadedly connected to the first connecting end 31, and the end cap 13 fixes the silicone sleeve 12 onto the first connecting end 31. The inner cavity of the silicone sleeve 12 matches the shape of the mounting rod of the fan blade 4, and the matching installation shape of the two can restrict the relative rotation of the silicone sleeve 12 and the fan blade 4.

[0032] In an optional embodiment, the second connecting end 32 and the silica gel sleeve 12 are provided with a shaft sleeve 14, the shaft sleeve body 141 of the shaft sleeve 14 is provided with a plurality of notches 143 and an engaging surface 142. The balance bar 5 is screwed on the second connecting end 32, the inside of the balance bar 5 is provided with a pressing surface, and the pressing surface is in contact with the engaging surface 142. The fan blade 4 is installed in the inside of the silica gel sleeve 12, one end of the fan blade 4 extends out of the silica gel sleeve 12, and the other end of the fan blade 4 extends into the inside of the balance bar 5. It should be noted that in the process of swinging of the fan blade 4, especially when the fan blade 4 swings in one direction, the balance bar 5 has a tendency to rotate in one direction. Since the pressing surface is in contact with the engaging surface 142, once the balance bar 5 is slightly rotated, the shaft sleeve body 141 is compressed and shrunk along the plurality of notches 143, so that the connection strength of the silica gel sleeve 12 and the fan blade 4 can be improved, and the same is true when the fan blade 4 swings in the other direction, but the fan blade 4 is still limited by the silica gel sleeve 12.

[0033] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
