Description

[Technical Field]

[0001] The present application relates to the technical field of oscillating fans, and more particularly to fans that can oscillate in all directions 360 degrees. [Background technology]

[0002] Conventional oscillating fans typically employ a dual gear structure to achieve three-dimensional oscillation, which requires a large number of components and is prone to gear wear and noise.

[0003] For example, utility model patent CN215486746U discloses an air circulation fan including a blower structure, a rear shell, a blower rotation structure, a fan box structure, a rear shell rotation structure, a conductive slip ring, and an electric control board, wherein the electric control board is attached to the rear shell or the air mesh structure and electrically connected to the blower rotation structure, the fan rotation structure, and the rear shell rotation structure via electric wires, and the conductive slip ring is attached to the electric wire and is located on the rear shell or the blower rotation structure and on the axis of the rotation shaft of the blower structure. The rear shell rotation structure includes a rear shell rotation motor, a rear shell rotation mounting bracket, a rear shell small gear, and a rear shell large gear, wherein the rear shell rotation mounting bracket is attached to the rear shell, the rear shell rotation motor is attached to the rear shell rotation mounting bracket, the rear shell small gear is fitted to the output shaft of the rear shell rotation motor, and the rear shell large gear is attached to the upper end of the fan box structure and meshes with the rear shell small gear, so that the rear shell rotation motor drives and rotates the rear shell.

[0004] First, the patent uses a dual-gear transmission structure, which is not only complex but also prone to gear wear and noise. Second, the patent requires the use of a separate component called a conductive slip ring, which is usually purchased separately and is therefore costly. Furthermore, the electrical control board in the patent is attached to the rear shell or air mesh structure, and the power line is usually connected from the bottom of the fan, so the power line must pass through the entire fan body to reach the electrical control board, making the wiring structure more complicated.

[0005] In view of the above-described prior art, there is therefore a need for a fan that is simple in structure, suffers little wear, is low in cost, and has simple wiring. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of this application is to provide a fan that can oscillate in all directions (360 degrees), which not only achieves the effect of omnidirectional oscillation but also avoids defects such as wear and noise caused by the use of gear structures. This application has a simple structure, low cost, simple wiring, and a small body size. [Means for solving the problem]

[0007] The present application relates to a fan that can oscillate 360 ​​degrees in all directions, comprising a head and a head bracket, the head bracket having a bearing with a rotatable rotary shaft installed inside, the head attached to the rotary shaft, a oscillating motor bracket having a oscillating motor installed inside the head bracket, and the output shaft of the oscillating motor connected to the rotary shaft, the oscillating motor bracket further having a conductive bracket, the conductive bracket having a first conductive member installed, the first conductive member electrically connected to a second conductive member, the second conductive member connected to the rotary shaft and installed rotatably relative to the first conductive member.

[0008] A head bracket cover plate may be provided between the head and the head bracket, the bearing may be installed on the head bracket cover plate, the first conductive member may be fixed to the conductive bracket by fixing claws, and the second conductive member may be installed on a third bracket, a conductive wire may be connected to the second conductive member to form a rotating assembly fixedly connected to the rotating shaft, the conductive wire may pass through the rotating shaft, the oscillating motor bracket may be provided with an insulating plate installed between the oscillating motor and the rotating assembly, and a conductive medium may further be provided between the second conductive member and the first conductive member.

[0009] The fan may include a base and a body assembly that can rotate relative to the base, and a third motor that can be connected to a turntable and driven to rotate the turntable may be provided within the base, a second bearing may be connected to the turntable, a second rotating shaft may be provided within the second bearing, and the second rotating shaft may be fixedly connected to the body assembly.

[0010] The first conductive member may be a conductive ring, the second conductive member may be arranged along the radial direction of the conductive ring, and the fan may further be provided with an electrical connector and an electrical control board arranged in a base. [Effects of the Invention]

[0011] The 360-degree oscillating fan according to the present invention has the following technical advantages. (1) The present application avoids defects such as wear and abnormal noise caused by the use of a gear structure by directly fixing and connecting the output shaft of the oscillating motor to the rotating shaft. (2) In this application, the first conductive member is installed on a conductive bracket, the second conductive member is fixedly connected to the rotating shaft, and the first conductive member is rotatably connected to the second conductive member. This avoids the high cost and drawbacks of using a conductive slip ring, and the conductive wires extending downward do not interfere with the conductive wires extending upward, preventing the conductive wires from becoming entangled. (3) In the present application, the electrical control board is installed within the base, and the power cord does not need to pass through the entire fan body to reach the electrical control board, as compared to when the power cord is installed in the rear shell of the head or in the air mesh structure, which simplifies the wiring and reduces the size of the body.

[0013] In order to clarify the objectives, technical solutions, and advantages of the present application, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that, unless a contradiction arises, the embodiments and features of the embodiments in the present application can be arbitrarily combined. The terms "fixed assembly" and "rotating assembly" in the present application are relative terms, meaning that the rotating assembly is rotatable relative to the fixed assembly, but do not necessarily mean that the components of the two assemblies are fixedly and rotatably installed, respectively.

[0014] As shown in Figures 1 to 6, the 360-degree oscillating fan according to the present application includes a head 10 and a head bracket 20. The head 10 is connected to the head bracket 20, and a mesh cover assembly is provided on the head 10. A head bracket cover plate 14 is provided between the head 10 and the head bracket 20. A drive motor 12 and a drive motor bracket 13 for driving the fan blades are provided within the head 10 or the mesh cover assembly. The drive motor 12 is fixed to the drive motor bracket 13, and a motor protection cover 11 is provided on the outside of the drive motor 12 to prevent conductive wires from coming into contact with the motor.

[0015] The head bracket cover plate 14 is provided with a bearing 29 having a rotatable rotation shaft 28 mounted therein, and the head 10 can be rotatably mounted on the rotation shaft 28 in all directions, which can rotate continuously in all directions, thereby achieving an omnidirectional oscillation effect. A oscillating motor bracket 23 to which an oscillating motor 21 is fixed is further provided within the head bracket 20. The output shaft of the oscillating motor 21 is connected to the rotation shaft 28 and is used to drive the rotation shaft 28 to rotate.

[0016] As shown in FIGS. 6 and 7, the oscillating motor bracket 23 further includes a fixing assembly, which includes a conductive bracket 24 attached to the oscillating motor bracket 23. The conductive bracket 24 includes a first conductive member 25 fixed to the conductive bracket 24 by a fixing claw on the first conductive member, and a conductive wire is connected to the first conductive member 25. A third bracket 27 includes a second conductive member 26 electrically connected to the first conductive member 25. The second conductive member 26 can rotate 360 ​​degrees relative to the first conductive member 25, and a conductive medium is provided at the contact surface between the first conductive member 25 and the second conductive member 26. The conductive wire is connected to the second conductive member 26 to form a rotating assembly fixedly connected to a rotating shaft 28 with a screw, and the conductive wire extending upward to the head passes through the rotating shaft. Preferably, an insulating plate 15 may be fixedly connected to the oscillating motor bracket to insulate the oscillating motor from the rotating assembly.

[0017] The first conductive member 25 preferably takes the form of a conductive ring, and multiple conductive rings can be arranged from the inside to the outside as needed. The second conductive member 26 is arranged along the radial direction of the conductive ring, and multiple second conductive members 26 can be arranged along the circumferential direction of the conductive ring. The second conductive member 26 can take the form of a conductive spring, conductive column, spring pin, or the like. In this application, the second conductive member 26 and the third bracket 27 rotate together with the rotation shaft, the conductive ring is fixed to the conductive bracket 24, and the conductive bracket 24 is fixedly attached to the oscillating motor bracket 23. That is, in this application, the second conductive member 26 can rotate relative to the first conductive member 25, thereby achieving dynamic electrical conduction.

[0018] During assembly, the bearing is fixed to the head bracket cover plate, and the rotating shaft is fitted into the bearing. The second conductive member 26 is riveted to the third bracket, and the connecting wire is connected to the second conductive member 26, forming a rotating assembly secured to the rotating shaft with screws. The connecting wire passes through the rotating shaft. The first conductive member 25 and the conductive bracket 24 form a fixed assembly. The first conductive member 25 is fixed to the conductive bracket 24 by the fixing hooks on the first conductive member 25, and the connecting wire is connected to the first conductive member. A conductive medium is placed at the contact surface between the first and second conductive members, and then the fixed assembly is fixed to the oscillating motor bracket with screws, and the insulating plate and oscillating motor are fixed to the oscillating motor bracket. The head bracket cover plate is fixed to the head bracket, and the head is attached to the rotating shaft. Next, the connecting wire of the second conductive member 26 and the motor connecting wire are secured via wire caps, and the motor is installed. At this point, the installation of the oscillating system is complete.

[0019] As shown in FIG. 1 , the main body of the present invention can be configured to rotate relative to the base 30. A third motor 39, which can be attached to the fixed plate 31, is provided within the base 30. The third motor 39 is connected to the turntable 38 via a connector and can drive the turntable 38 to rotate. The turntable 38 is connected to a second bearing 37, and a second rotating shaft 36 is provided within the second bearing 37, and the second rotating shaft 36 is fixedly connected to the main body assembly. In the present invention, the turntable 38 is driven to rotate via the third motor 39, and the turntable 38 rotates the second rotating shaft 36 and the main body assembly together. The fan of the present invention continuously oscillates in all directions, creating a three-dimensional airflow effect and improving the user experience. The three-dimensional oscillation process can be linked to the left and right oscillation to change various angles, thereby more efficiently improving the air circulation effect and significantly reducing material costs compared to using a conductive slip ring alone.

[0020] The base 30 is provided with an electrical connector 40 for connecting to an external power source. An electrical control board 33 connected to the electrical connector 40 is also provided within the base 30. Preferably, an indicator lamp with a lampshade 34 may also be provided within the base 30, and a display window 41 for displaying the status of various control buttons is provided on the top plate 35 of the base 30 at a position corresponding to the lampshade 34. In this application, by locating the electrical control board 33 within the base 30, the connection length of the conductive wires can be shortened, avoiding the drawbacks of wires passing continuously through the main body, such as difficulty in wiring and tangling. This not only reduces the amount of wire used compared to when the conductive wires are installed within the head assembly, but also, more importantly, avoids problems such as tangling and difficulty in passing wires through the main body, particularly the upper swing assembly, as well as the need for oversized bearings and other wire-passing components.

[0021] Although the embodiments disclosed in the present application are as described above, the above contents are merely embodiments adopted to facilitate understanding of the present application and are not intended to limit the present application. Those skilled in the art may make modifications and changes to the form and details of the embodiments without departing from the spirit and scope of the present application, but the scope of protection of the invention of the present application shall be based on the scope defined by the scope of the attached utility model registration claims.
