The rotating fan shown in Figure 1-7 includes a battery 5, a control component 4, a fan blade component 1, and a support for installing the fan blade component 1. The control component 4 is electrically connected to the battery 5, the fan blade component 1, and the support. include:

A fixed base 2, which is located at the bottom of the fan to form a supporting effect;

The movable seat 3 is movably installed on the fixed seat 2;

The driving assembly is arranged between the fixed seat 2 and the movable seat 3 to control the movement of the movable seat 3 relative to the fixed seat 2 to adjust the state of the first direction of the fan blade assembly 1;

In addition, the fan blade assembly 1 is movably mounted on the movable seat 3 to move to realize the adjustment of the second direction state.

The fixed seat 2 is located at the bottom of the entire fan structure layout. When in use, the fan is placed on the corresponding ground, table, etc. The movement of the movable seat 3 can adjust the orientation of the fan blade assembly 1 in the first direction. The adjustment of the second direction is achieved by the movement of the fan blade assembly 1 compared to the movable seat 3. For example, the movable seat 3 is rotated or moved back and forth linearly compared to the fixed seat 2, and the fan blade assembly 1 is turned upside down and rotated compared to the movable seat 3, and the movement of the two structures realizes multi-directional adjustment of the fan wind direction. More flexible and larger wind direction adjustment range, which can better meet user needs.

In some embodiments, the driving assembly includes a driving motor and a gear ring 20. The driving motor and the gear ring 20 are separated on the movable seat 3 and the fixed seat 2. The output gear 33 on the driving motor meshes with the gear ring 20, and the output The gear 33 is driven by the driving motor to move along the gear ring 20 so that the movable seat is rotated relative to the fixed seat.

The implementation of the foregoing embodiments may include: first, the driving motor is installed on the movable seat 3, the gear ring 20 is correspondingly arranged on the fixed seat 2, the output gear 33 and the gear ring 20 are in an intermeshing state to start driving During the rotation of the output gear 33 after the motor rotates along the inner circumference of the gear ring 20, the movable seat 3 is driven to rotate relative to the fixed seat 2, thereby adjusting the orientation of the fan blade assembly 1. Secondly, the driving motor is arranged on the fixed seat, and the gear ring is arranged on the movable seat. The cooperation relationship still refers to one of the foregoing, and the relative rotation between the movable seat 3 and the fixed seat 2 can also be achieved. Thirdly, the gear ring 20 means that its shape is a hollow ring, and its tooth pattern is provided on its annular edge. Specifically, as described in the first, a tooth pattern can be formed on its inner ring (also as shown in Figures 2, 4, and 7 of the drawings). (Shown), at this time, the output gear 33 and the gear ring 20 are inscribed meshing; of course, it also includes the formation of a tooth pattern on the outer ring. At this time, the output gear 33 and the gear ring 20 are equivalently meshing with each other. Driven by the motor, the lower output gear 33 revolves around the periphery of the gear ring 20 while rotating, and the relative rotation between the movable seat 3 and the fixed seat 2 can also be achieved.

Specifically, an inner cavity 30 is formed in the movable seat 3, and a battery 5, a control module 4 (wherein the control chip model can be MT3608 or FP6293) and a drive motor (such as a stepper motor of model N2003A) are installed in the inner cavity 30. The output gear 33 penetrates downward from the bottom plate 31 of the inner cavity 30 to achieve meshing with the gear ring 20 on the upper surface of the fixing base 2.

In order to realize the rotation of the movable seat 3 compared to the fixed seat 2, a variety of existing structural assembly methods can be referred to, for example, a rotating shaft and a shaft hole, an annular groove and an annular convex strip are used. In this case, the shaft member 6 is preferably used. The assembly of the shaft member 6 satisfies the following two functions. One is that the movable seat 3 can rotate relative to the fixed seat 2 with the cooperation of the shaft member 6. The second is to fix the fixed seat 2 by the shaft member 6. The movable seat 3 is connected as a whole (generally a detachable fixed connection). Specifically, the rotating shaft member 6 is fixed below the bottom plate 31 of the movable seat 3, which is generally disk-shaped as shown in the figure; the fixed seat 2 is provided with a shaft hole 22 that cooperates with the rotating shaft member 6, and the upper end of the shaft hole 22 is contracted to prevent the rotating shaft member 6 from upward Putting on and taking off, that is, the diameter of the lower end of the shaft member 6 is slightly larger, and after the upper end of the shaft hole is contracted, the shaft member 6 can be completely prevented from coming out, and then the shaft member 6 is fixed to the bottom plate 31 of the movable seat 3 by using a connecting member such as a bolt. Of course, it is also possible to change the setting, and fix the bottom end of the rotating shaft member 6 to the fixed seat 2, and the top end of the shaft member 6 and the bottom plate 31 of the movable seat 3 can be rotated and assembled.

In order to enhance the stability and smoothness of the movable seat 3 and the fixed seat 2 during relative rotation, a plurality of movable balls 7 may be installed between the two. Specifically, a ring member 8 is provided at the assembly place of the movable seat 3 and the fixed seat 2. For example, a ring 21 is arranged on the upper surface of the fixed seat 2, and the ring member 8 fits inside the ring 21 and the ring member 8 There are through holes corresponding to the number of the balls 7, each of the balls 7 is movably installed in each of the through holes, and the upper and lower parts of each of the balls 7 are exposed through the corresponding through holes to be located on the movable seat 3 and the fixed seat 2. Annular groove fit. When the movable seat 3 is rotated horizontally compared to the fixed seat 2, the ball 7 and the annular groove cooperate to play a guiding role, and at the same time, the boosting force is increased, so that the rotation is smoother and more stable.

For the specific installation of the fan blade assembly 1, it is preferable to adopt the following manner, a sinking step 32 is formed on one side of the movable seat 3, and the fan blade assembly 1 is rotatably mounted on a side wall surface 320 of the sinking step 32. Specifically, the side wall surface 320 of the sinking step 32 is provided with a groove 321, and the horizontal rotation shaft on the fan cover of the fan blade assembly 1 is installed in the shaft hole of the wall surface of the groove 321 to realize the upper and lower parts of the fan blade assembly 1. Flip and turn. When turning down, you can fold the fan cover to a horizontal position. When turning it up, you can fold the fan cover to be perpendicular to the horizontal plane. The horizontal rotating shaft may have a large length at at least one end. Therefore, when the horizontal rotating shaft is inserted into the inner cavity of the movable seat through the shaft hole of the groove, the horizontal rotating shaft may be limited in the inner cavity by using a pressing plate of a corresponding length. The combination of the horizontal rotating shaft and the pressure plate can more firmly and stably assemble the fan blade assembly on the movable seat.

In some embodiments, a light assembly 9 is installed on the movable seat 3 to increase the accessory function of the fan. The rotation of the movable seat 3 can also adjust the lighting direction of the light assembly 9, which can better meet the random needs in the outdoor environment. .
