DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] refer to Figures 1 to 7 A fan comprises a base 1, a column 2, an angle adjustment mechanism 5, a shaking mechanism 4 and a fan assembly 3 connected in sequence;

[0034] The angle adjustment mechanism 5 can adjust the angle of the fan assembly 3 in the vertical direction;

[0035] The shaking mechanism 4 can drive the fan assembly 3 to rotate back and forth in the horizontal direction;

[0036] The oscillating mechanism 4 includes a support shaft 44, the upper end of the support shaft 44 is rotatably connected to the bracket 31 of the fan assembly 3, and the lower end of the support shaft 44 is swingably connected to the column 2 in the vertical direction;

[0037] The shaking head mechanism 4 can cause the fan assembly 3 to automatically rotate back and forth in the horizontal direction, and the angle adjustment mechanism 5 can cause the fan assembly 3 to manually adjust the angle in the vertical direction. Therefore, the combination of the shaking head mechanism 4 and the angle adjustment mechanism 5 can achieve adjustment and air supply at more angles, with more powerful functions and more convenient use.

[0038] refer to Figure 2 and Figure 3 , the adjustment angle of the angle adjustment mechanism 5 is equal to or greater than 90 degrees. Figure 2 The status shown is adjusted to Figure 3 The state shown can also be adjusted arbitrarily between the two states.

[0039] refer to Figure 5 , the shaking mechanism 4 includes a first motor 41, a first gear 42, a second gear 43 and a support shaft 44;

[0040] The upper shaft section 441 of the support shaft 44 is connected to the first shaft hole 311 of the bracket 31, which not only realizes relative rotation connection, but also supports the fan assembly 3.

[0041] The first motor 41 is fixed to the bracket 31. The first motor 41 can be fixed to the upper part of the bracket 31 by screws or the like. The output end of the first motor 41 passes through the bracket 31 and extends to the lower part of the bracket 31. The first gear 42 is located below the bracket 31. The output end of the first motor 41 is linked to the first gear 42.

[0042] The first gear 42 is meshed with the second gear 43; the second gear 43 is linked with the support shaft 44;

[0043] Thus, the fan assembly 3 is driven to rotate by the cooperation of the first motor 41 , the first gear 42 , the second gear 43 and the like.

[0044] The second gear 43 and the support shaft 44 are integrally formed, for example, by injection molding, which is easy to manufacture and simplifies the assembly process. The second gear 43 is arranged below the upper shaft section 441.

[0045] refer to Figure 5 , the angle adjustment mechanism 5 includes a bolt 51, a nut 52 and a support 53;

[0046] The support 53 is provided at the top of the column 2. The support 53 can be partially inserted into the column 2 and fixed by screws. The top of the support 53 is provided with two oppositely arranged lugs 531. The two lugs 531 form a groove 532 capable of accommodating the lower shaft section 442 of the support shaft 44.

[0047] The lower shaft section 442 is provided with a second shaft hole 443, and the lug 531 is provided with a corresponding third shaft hole 533. The bolt 51 is passed through the third shaft hole 533 and the second shaft hole 443 and connected to the nut 52. The bolt 51 is used as both a rotating shaft and a fastener.

[0048] As a result, the two lugs 531, under the action of the bolts 51, abut against the side surfaces of the lower shaft section 442 of the support shaft 44, causing a certain friction torque to be generated between the lower shaft section 442 and the lugs 531. This torque can stabilize the vertical angle of the fan assembly 3 in the absence of external force. Under the action of external force, the vertical angle of the fan assembly 3 can be adjusted. For example, a user can apply external force to cause the support shaft 44 to rotate in the vertical direction, thereby adjusting the vertical angle of the fan assembly 3. When the desired angle is adjusted, the external force is removed, and the support shaft 44 is stabilized by the friction force, thereby fixing the vertical angle of the fan assembly 3.

[0049] refer to Figure 5 The angle adjustment mechanism 5 further includes a sheath 54, which is sleeved on the lower shaft section 442. The provision of the sheath 54 enables the lower shaft section 442 of the support shaft 44 to better contact the lug 531 to form a corresponding friction force.

[0050] refer to Figure 6, base 1, the bottom of the column 2 can be inserted into the base 1 and fixed by screws;

[0051] The base 1 is provided with a battery 6 and a DC interface 7, the DC interface 7 is electrically connected to the battery 6, and the first motor 41 is electrically connected to the battery 6. The second motor 30 of the fan assembly 3 is electrically connected to the battery 6 and is used to drive the fan blades to rotate.

[0052] Battery 6 provides power for the fan, and DC port 7 can be connected to an external power source, enabling multiple power supply modes and making it more convenient to use. Furthermore, the fan of the present disclosure operates at 5V 15W, allowing it to charge while operating, without affecting normal operation.

[0053] refer to Figure 7 The base 1 further includes a circuit board 8, which includes a processing chip 80 and a Bluetooth chip 81. The Bluetooth chip 81 is signal-connected to the processing chip 80, and both the first motor 41 and the second motor 30 are signal-connected to the processing chip 80. The processing chip 80 and the Bluetooth chip 81 are both conventional technologies. Thus, commands such as starting and stopping the fan or starting and stopping the first motor 41 can be sent to the fan via Bluetooth communication, enabling remote control. Users can install an app on a mobile phone or other terminal to control the fan.

[0054] The above disclosure is only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
