[0029] In the related art, the fan can generally make the fan assembly rotatably connected with the support, so that the fan assembly can swing by a certain angle along the up-down direction, so that the blowing angle of the fan can be adjusted by swinging the fan assembly. However, the transmission wire in the fan is mostly routed by directly passing through the support and the fan assembly, which causes the transmission wire to be easily pulled when the fan swings to adjust the blowing angle of the fan assembly, and the transmission wire is easily disconnected from the connection with the fan assembly, affecting the stable and reliable operation of the fan and reducing the structural stability and reliability of the fan. It can be understood that, in order to avoid the transmission wire from interfering with the rotating parts of the fan assembly between the fan assembly and the support, the transmission wire is usually provided with a relatively short reserved line segment between the fan assembly and the support, which causes the transmission wire to be easily subjected to force during the up-down swinging of the fan assembly, and long-term use can cause the transmission wire to be easily disconnected from the fan body and the circuit board in the fan assembly, affecting the electrical connection stability of the fan. In view of the above problems, the utility model provides a fan 100.

[0030] Please refer to Figures 1 to 6 In an embodiment of the utility model, the fan 100 includes a fan assembly 10, a support 20, a rotating shaft 30, and a transmission wire 40.

The end of the support 20 can be provided with a second connecting piece 251, which can be a seat structure or a plate structure extending upward, and can be made of a material with high structural strength, such as sheet metal, structural steel, etc. The material and structure of the second connecting piece 251 can be various, and the present application does not limit it as long as it can achieve stable support.

Of course, the first limiting structure and the second limiting structure can also adopt other structures matched with each other, and the application does not limit the structure form of the first limiting structure and the second limiting structure, as long as the first connecting piece 11 can be limited to rotate a certain angle relative to the second connecting piece 251 when the first limiting structure and the second limiting structure are matched and abutted. Further, when the first connecting piece 11 rotates a certain angle around the rotating shaft 30 relative to the second connecting piece 251, the first limiting structure and the second limiting structure can abut each other, thereby limiting the rotation angle of the first connecting piece 11, effectively preventing the first connecting piece 11 from rotating too large relative to the second connecting piece 251, which may cause the components in the fan 100 to collide with each other. For example, the transmission gear 53 of the driving motor can be prevented from colliding with the end of the transmission rack 117, or the first connecting piece 11 and the second connecting piece 251 can be prevented from colliding with each other, so that the fan 100 can operate more stably and reliably.

[0057] In order to achieve a better swing angle of the fan 100, the first limiting structure and the second limiting structure can abut each other when the first connecting piece 11 rotates to drive the fan assembly 10 to blow horizontally, and can abut each other when the first connecting piece 11 rotates to drive the fan assembly 10 to blow vertically upward, so that the fan 100 can cover a larger blowing range. Of course, under the condition of meeting the mutual avoidance of various components of the fan 100, the first limiting structure and the second limiting structure can abut each other when the first connecting piece 11 rotates a larger angle, so that the fan 100 can better meet the use requirements, and the application does not limit the rotation range of the first connecting piece 11 limited by the first limiting structure and the second limiting structure.

[0065] When the fan 100 swings up and down by driving the first connecting piece 11 by the driving device 50, the bearing structure 31 is adopted to reduce the friction between the rotating shaft 30 and the first connecting piece 11 and the second connecting piece 251, which is also beneficial to reduce the load of the driving device 50, thereby reducing the power demand of the driving device 50 to drive the fan assembly 10 to swing, and further reducing the production cost of the fan 100. In addition, when the first connecting piece 11 and the second connecting piece 251 are provided in a sheet metal plate structure, the bearing structure 31 can further comprise a bearing sleeve and a bearing body, the bearing sleeve is installed and connected on the first connecting piece 11 and / or the second connecting piece 251, and the bearing body is installed and fixed in the bearing sleeve, the shaft body 33 passes through the through holes at both ends of the bearing sleeve and is matched with the bearing body, which can better improve the connection stability of the bearing structure 31 and the first connecting piece 11 or the second connecting piece 251, without needing to process a limiting structure for installing the bearing body on the first connecting piece 11 and the second connecting piece 251 made of sheet metal material, thereby reducing the processing difficulty and cost of the first connecting piece 11 and the second connecting piece 251, and further improving the practicability and structural reliability of the fan 100.

[0066] In addition, the shaft body 33 can be clamped and installed with a retaining ring at both ends, the retaining ring can abut against the first connecting piece 11 or the second connecting piece 251 to limit the installation of the shaft body 33, effectively preventing the shaft body 33 from moving along the central axis direction, i.e. limiting the shaft body 33 from moving in the left-right direction, which is beneficial to further reduce the friction between the bearing and the first connecting piece 11 and the second connecting piece 251, and simultaneously reduce the abrasion and noise generated by the movement of the shaft body 33, thereby further improving the structural stability and reliability of the fan 100.
