[0029] Please refer to the accompanying Figures 1-5 The purpose of the present embodiment is to provide an electric swing fan with a balancing mechanism, comprising: a rack 6, a driving device 11 is fixedly installed on the mounting plate 61 of the rack 6, the driving device 11 is preferably a motor, the driving device 11 is connected to an oscillating member 3 through an adaptor 8, the oscillating member 3 is installed with a fan blade 4 and a balance bar 5; an arc-shaped stop block 15 is fixedly arranged on the mounting plate 61, the two ends of the arc-shaped stop block 15 are respectively a first limiting end 151 and a second limiting end 152; an arc-shaped swing block is arranged on the adaptor 8, the two ends of the arc-shaped swing block are respectively a first reset end 81 and a second reset end 82.
[0030] In the normal operation of the electric 11 swing fan, the driving device 11 drives the arc-shaped swing block of the adapter 8 to reciprocate between the first limiting end 151 and the second limiting end 152, and the first reset end 81 is not in contact with the first limiting end 151, and the second reset end 82 is not in contact with the second limiting end 152, the fan blade 4 is cooperatively installed with the balance bar 5, so that the driving device 11 is balanced; through the above structure, the efficient swing of the fan is realized. It should be pointed out that when the electric swing fan fails, the adapter 8 is driven by the driving device 11, the first reset end 81 is in contact with the first limiting end 151, or the second reset end 82 is in contact with the second limiting end 152, the reset of the fan blade is realized, that is, the initial reset of the driving device 11, so that the driving device 11 can swing within a certain range.
[0031] Specifically, the output shaft of the driving device 11 is fixedly connected with the adapter 8; the adapter 8 is provided with a mounting hole 83, and the mounting hole 83 is fixedly connected with the swing piece 3 through a screw 10. The rack 6 is installed on the base 1, and the base 1 is provided with a shell 2, and the shell 2 covers the rack 6. The swing piece 3 is fixedly connected with the inner ring of the bearing 9, and the bearing 9 is fixedly installed on the shell 2, which reduces the resistance of the fan blade 4 during swing.
[0032] Further, the bottom of the base 1 is provided with a plurality of suction cups 7 arranged uniformly, and the suction cups 7 can adsorb the swing fan on the desktop, which is convenient to use.
[0033] In the embodiment, the swing piece 3 is provided with a first connecting end 31 and a second connecting end 32, and the outer parts of the first connecting end 31 and the second connecting end 32 are respectively provided with threads. The swing piece 3 is internally provided with a silica gel sleeve 12, the silica gel sleeve 12 extends from the first connecting end 31 to the second connecting end 32 of the swing piece 3, and the end cap of the silica gel sleeve 12 is overlapped on the outside of the first connecting end 31; the end cover 13 is threadedly connected with the first connecting end 31, and the end cover 13 fixes the silica gel sleeve 12 on the first connecting end 31. The inner cavity of the silica gel sleeve 12 is matched with the outer shape of the mounting rod of the fan blade 4, and the matching installation shapes of the two can limit the relative rotation of the silica gel sleeve 12 and the fan blade 4.
[0034] 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.
[0035] 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.
