Referring to fig. 3 to 7, in the present embodiment, a fan blade driving assembly is further disposed in the housing assembly 2, the fan blade driving assembly includes a fan motor 42 and a fan blade 41 connected to an output shaft of the fan motor 42, and a synchronous motor bracket is disposed on a side of the fan motor 42. The oscillating structure 4 comprises an oscillating bracket 43, an angle handle 44, a connecting rod 47 and a synchronous motor 45. Synchronous machine 45 is fixed mounting on the synchronous machine support to realize synchronous machine 45 fixed mounting in fan blade drive assembly's side. The fan blade driving assembly is hinged with the oscillating bracket 43 through the rotating shaft 40, and in the working process, the fan blade driving assembly mainly performs oscillating motion around the rotating shaft 40, and the driving source of the oscillating motion is a synchronous motor 45.

Referring to fig. 4, an output shaft of the synchronous motor 45 is fixedly connected with an eccentric lobe 46, a bottom surface of the eccentric lobe 46 extends downward to form an eccentric shaft, and an end of the eccentric shaft is hinged with one end of a connecting rod 47 to form a crank-connecting rod mechanism. For example, a hinge hole may be formed at an end of the connecting rod 47, and the eccentric shaft may be inserted into the hinge hole, so that the hinge between the connecting rod 47 and the eccentric shaft is realized by the cooperation of the shaft and the hole. The other end of the link 47 is hinged to one end of the angle handle 44 by a first hinge 51. Similarly, a hinge hole may be formed again at the end of the link 47, and the top surface of the angle handle 44 extends upward to form a hinge post through which the hinge post is inserted into the hinge hole to form a hinge. In order to prevent the angle handle 44 from being released, the angle handle 44 and the link 47 may be prevented from being released by a screw or a bolt. In this embodiment, the other end of the angle handle 44 extends outward to the outside of the oscillating bracket 43 and is exposed outside the casing assembly 2, so that the casing assembly 2 does not need to be disassembled, and the oscillating angle of the fan can be adjusted by directly adjusting the angle handle exposed outside the casing assembly.

The angle handle 44 is hinged to the swing bracket 43 through the second hinge 52, and the second hinge 52 may be a rotating shaft or the like, as long as the angle handle 44 can swing relative to the swing bracket 43. An adjusting mechanism for adjusting the swing range of the connecting rod 47 is arranged between the angle handle 44 and the swing bracket 43. With reference to fig. 5 to 7, the adjusting mechanism includes three first positioning holes 71 provided on the swing support 43, the three first positioning holes 71 are arranged at intervals and corresponding swing angles are 40 °, 60 ° and 80 °, and distances between each first positioning hole 71 and the second hinge 52 are equal, that is, each first positioning hole 71 is on the same arc. The adjustment mechanism further comprises a first projection 61 formed on the bottom surface of the angle handle 44, the first projection 61 snapping into one of the first positioning holes 71 in the assembled state.

In order to improve the fixation of the angle handle 44, a limiting mechanism is arranged between the angle fixing piece 48 and the angle handle 44. The limiting mechanism is similar to the adjusting mechanism and includes a second positioning hole 72 formed in the angle fixing plate 48 and a second protrusion 62 formed on the top surface of the angle handle 44. The second positioning holes 72 are provided in plural, the plural second positioning holes 72 are arranged at intervals, and the distances between each second positioning hole 72 and the second hinge 52 are equal; in the assembled state, the second boss 62 is inserted into one of the second positioning holes 72.

During the operation of the fan, the fan motor 42 drives the fan blades 41 to rotate. The oscillating mechanism is activated, the synchronous motor 45 starts to rotate, the synchronous motor 45 guides the eccentric lobe 46 to rotate, the eccentric shaft of the eccentric lobe 46 makes a circular motion and pushes the connecting rod 47 to oscillate relative to the first hinge 51. Since the swing bracket 43 and the angle knob 44 are fixed and do not move, the swinging of the connecting rod 47 is converted into the rotation of the fan driving assembly relative to the rotating shaft 40, thereby realizing the swing motion of the fan driving assembly. Referring to fig. 5 to 7, if the swing angle needs to be adjusted, the manual toggle angle handle 44 swings around the second hinge 52, and the first protrusion 61 is inserted into the other first positioning hole 71. Similarly, the second protrusion 62 is inserted into another second positioning hole 72 to change the position of the first hinge 51 as the swing center, so as to change the swing center of the connecting rod 47, and indirectly change the swing range of the fan driving assembly.
