Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to an automatic rotation mechanism for a circulating fan. Background Technology

[0002] A circulating fan is an electrical device that promotes efficient circulation of indoor air. Unlike traditional fans that only provide localized cooling by blowing air, it uses unique designs such as large-angle spiral blades and directional airflow shrouds to create a strong and concentrated spiral airflow that quickly stirs the indoor air, breaking the static and stratified state of the air in the space and allowing hot and cold air to mix rapidly and evenly.

[0003] Currently, existing circulating fans usually require manual adjustment to change the airflow angle. Although this can change the basic airflow direction, it cannot automatically adjust to the appropriate angle in real time and accurately according to the actual usage scenario. The operation process is time-consuming and laborious and it is difficult to achieve the desired effect, making it difficult for users to quickly obtain a suitable airflow experience in different environments. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot automatically and accurately adjust to the appropriate angle in real time according to actual usage scenarios, making it difficult for users to quickly obtain a suitable blowing experience in different environments. Therefore, this invention proposes an automatic rotation mechanism for circulating fans.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic rotation mechanism for a circulating fan includes:

[0007] The fan body and the ring frame, wherein a U-shaped frame is fixedly installed at the top of the fan body;

[0008] One end of the U-shaped frame is equipped with a drive mechanism, which is used to drive the ring frame to rotate and change its angle. The other end of the U-shaped frame is equipped with a self-rotating component, which is used to cooperate with the drive mechanism to make the ring frame rotate and change its angle.

[0009] In one possible design, the drive mechanism includes a second shaft bracket fixed to one end of a U-shaped frame by screws. A second bearing seat is provided on the front side of the second shaft bracket. A second bearing is embedded in the inner ring of the front side of the second bearing seat. The inner ring of the second bearing is fixed to the outside of the shaft of the second shaft bracket. The inner ring of the second bearing seat is fixed with evenly distributed internal teeth. A stepper motor is embedded in the rear side of the second shaft bracket. An external gear is fixed at one end of the output shaft of the stepper motor. The external gear passes through the second shaft bracket and meshes with the internal teeth for transmission. A second pressure cap is fixed on the front side of the second bearing seat.

[0010] In one possible design, the self-rotating assembly includes a shaft frame 1 fixedly mounted inside the other end of the U-shaped frame by screws, a bearing seat 1 provided on the front side of the shaft frame 1, a bearing 1 embedded in the inner ring of the bearing seat 1, the inner ring of the bearing 1 fixedly mounted outside the shaft of the shaft frame 1, and a pressure cap 1 fixedly mounted on the front side of the bearing seat 1.

[0011] In one possible design, the two sides of the ring frame are respectively fixedly connected to bearing housing one and bearing housing two by bolts, and a connecting frame is fixedly installed on the outside of the ring frame.

[0012] In one possible design, a mesh cover is fixedly installed on the rear side of the ring frame and the front side of the connecting frame.

[0013] In one possible design, a motor is fixedly mounted on the front side of the mesh cover located behind the ring frame, and fan blades are fixedly mounted on the outside of the output shaft of the motor.

[0014] In this application, upon initial use, installation is performed first. Bearing 1 and Bearing 2 are then embedded into Bearing Housing 1 and Bearing Housing 2, respectively. Next, the shafts on Shaft Support 1 and Shaft Support 2 are inserted into the inner rings of Bearing 1 and Bearing 2, respectively, and secured to Bearing Housing 1 and Bearing Housing 2 with retaining rings to ensure stable rotation of the bearing housings around the shafts of the shaft supports. Then, Pressure Cap 1 and Pressure Cap 2 are installed on the front sides of Bearing Housing 1 and Bearing Housing 2, respectively, for fixation and protection. Finally, the two installed Shaft Supports 1 and Shaft Support 2 are installed inside the two ends of the U-shaped frame, thus securing the entire drive mechanism and self-rotating assembly. Mount the fan on the U-shaped frame, then install the motor and fan blades inside one of the guards, and install the guard on the back of the ring frame. Next, install the connecting frame on the outside of the ring frame, and install the other guard on the front of the connecting frame to complete the assembly of the main fan body. Then, place the assembled ring frame between the two ends of the U-shaped frame in the middle position. Then, use bolts to fix bearing housing one and bearing housing two to the two sides of the ring frame respectively. Then, install shaft bracket one and shaft bracket two to the two ends of the U-shaped frame to ensure that the entire rotating mechanism is firmly connected. After installation, install the cover on both sides of the U-shaped frame for protection and aesthetic purposes.

[0015] After installation, power on the fan body and press the button (or remote control) to power the motor on the fan body. When the motor is working, it drives the fan blades to rotate and blow air. When you need to adjust the blowing angle, press the button (or remote control) to start the stepper motor. The output shaft of the stepper motor drives the external gear to rotate. Since the bearing housing two is driven by the meshing transmission between the internal gear and the external gear, the rotation of the external gear drives the bearing housing two to rotate. Because the bearing housing two is fixedly connected to the ring frame, the rotation of the bearing housing two will drive the ring frame to rotate on the U-shaped frame to adjust the angle. At the same time, since the other side of the ring frame is fixedly connected to the bearing housing one, the rotation of the ring frame will drive the bearing housing one to rotate synchronously around the axis of the ring frame one, thereby ensuring the smoothness of the ring frame rotation and realizing the automatic adjustment of the blowing angle.

[0016] This utility model has the following beneficial effects:

[0017] The present invention, through the setting of the drive mechanism, can precisely drive the ring frame to rotate to change the fan blowing angle, realize the automatic adjustment of the blowing direction, improve the flexibility and convenience of fan use, and meet the blowing needs of users in different scenarios.

[0018] In this invention, the self-rotating component can move synchronously with the drive mechanism. When the ring frame is driven to rotate by the drive mechanism, it rotates smoothly, effectively sharing the force on the ring frame during rotation, enhancing the stability and smoothness of the ring frame rotation, reducing shaking and jamming during rotation, and improving the overall reliability and service life of the fan rotation mechanism.

[0019] This invention combines a drive mechanism with a self-rotating component, which not only enables flexible adjustment of the fan's blowing angle to meet the blowing needs of different scenarios, but also effectively distributes the radial and axial loads of the ring frame, enhancing the stability and smoothness of the rotation process, and significantly improving the fan's operational stability and service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

The second bearing housing 8 is located on the front side of the second shaft bracket 7, and the second bearing 9 is embedded in its front inner ring. The inner ring of the second bearing 9 is fixedly mounted outside the shaft of the second shaft bracket 7, allowing the second bearing housing 8 to rotate flexibly relative to the second shaft bracket 7. The rear inner ring of the second bearing housing 8 is fixedly provided with evenly distributed... The inner gear 801 of the cloth is embedded in the rear side of the shaft frame 7. A stepper motor 11 is embedded in the rear side of the shaft frame 7. An external gear 10 is fixedly installed at one end of the output shaft of the stepper motor 11. The external gear 10 passes through the shaft frame 7 and meshes with the inner gear 801 for transmission. When the stepper motor 11 starts, its output shaft drives the external gear 10 to rotate. Since the external gear 10 meshes with the inner gear 801, it drives the bearing seat 8 to rotate around the shaft of the shaft frame 7. The pressure cover 12 is fixedly installed on the front side of the bearing seat 8, which plays the role of protecting and fixing the internal parts.

[0031] The self-rotating assembly includes a shaft frame 3, a bearing housing 4, a bearing 5, and a pressure cap 6.

The bearing housing 4 is located on the front side of the shaft frame 3, and the bearing 5 is embedded in its inner ring. The inner ring of the bearing 5 is fixed outside the shaft of the shaft frame 3, allowing the bearing housing 4 to rotate freely relative to the shaft frame 3. The pressure cap 6 is fixed on the front side of the bearing housing 4 to protect and fix the internal parts. The function of the self-rotating assembly is to cooperate with the drive mechanism when the drive mechanism drives the ring frame 13 to rotate, sharing the radial and axial loads generated during the rotation of the ring frame 13, and enhancing the smoothness and stability of the rotation.

[0032] This application can be used in the field of automatic rotation technology of circulating fans, or in other fields applicable to this application.

A connecting frame 14 is fixedly provided on the outside of the ring frame 13, and the connecting frame 14 is used to connect other components of the fan.

[0035] A mesh cover 15 is fixedly installed on the rear side of the ring frame 13 and the front side of the connecting frame 14. The mesh cover 15 serves to protect the fan blade 17 and prevent personnel from touching the fan blade 17, thus ensuring safe use.

[0036] A motor 16 is fixedly installed on the front side of the mesh cover 15 located behind the ring frame 13. A fan blade 17 is fixedly installed on the outside of the output shaft of the motor 16. When the motor 16 starts, it drives the fan blade 17 to rotate at high speed, thereby generating airflow and realizing the blowing function of the fan.
