Description

Technical Field

[0001] This invention relates to the field of circulating fan technology, specifically to a super 360-degree circulating fan with a lever slider structure. Background Technology

[0002] An air circulator fan is somewhat like a turbine engine on an airplane. Its main structure includes a drive motor, a turbine fan, a baffle grille, and a cylindrical casing. Unlike ordinary fans, air circulator fans can direct airflow in a spiral pattern, creating a columnar, spiral-shaped column of air as the blades churn. The airflow from an air circulator fan travels a relatively long distance and has good directionality.

[0003] Many fans currently aim to achieve three-dimensional oscillation, but existing circulating fans still have the following shortcomings in practical use: 1. Cannot achieve true 360° oscillation: Nowadays, there are many types of fans on the market that can oscillate, but the oscillation angle is limited. The oscillation angle of a fan is achieved through its internal structure.

[0004] 2. The main reason why 360° oscillation structure fans on the market cannot achieve 360° oscillation is that the reciprocating column and the rotating shaft gear are fixed as one piece, and the reset iron plate is also fixed. This causes the reset column and the reset iron plate to block when the large gear rotates to the end. Since the reset column cannot move and has a thickness, the large gear cannot rotate 360° completely when rotating.

[0005] To address the aforementioned issues, we provide a super 360-degree circulating fan with a baffle slider structure to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a super 360-degree circulating fan with a paddle slider structure to solve the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A super 360-degree circulating fan with a paddle slider structure includes a bottom shell, an upper end of which is provided with a mounting basin, a rotating middle plate is rotatably connected inside the mounting basin, arc-shaped limiting holes are provided on both sides of the mounting basin, and a first limiting component for limiting the rotating middle plate by cooperating with the arc-shaped limiting holes is also provided on the rotating middle plate. The rotating plate is also equipped with a swing assembly for driving the rotating plate to swing. A rotating platform is fixedly connected to the rotating plate. An inclined bracket is installed on the inclined surface at the upper end of the rotating platform. A central ring is provided in the middle of the inclined bracket. A bearing is installed in the center of the central ring. A rotating shaft gear is installed inside the bearing. A drive assembly for driving the rotating shaft gear to rotate more than 360 degrees is also provided on the inclined bracket. The rotating shaft gear connecting shaft is fixedly connected to a rear screen at the position where it passes through the rotating platform, and the rear screen is equipped with a blower assembly for generating wind.

[0008] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative: the first limiting component includes limiting pins, which are fixedly connected to the positions on both sides of the rotating plate, and the two limiting pins pass through arc-shaped limiting holes, with limiting pads fixedly connected to the positions where the ends of the limiting pins pass through the arc-shaped limiting holes.

[0009] In one alternative: the oscillating assembly includes a second oscillating motor, which is fixedly connected inside the rotating plate. A central arc hole is also provided on one side of the lower end of the mounting base. A crankshaft is installed at the position where the output end of the second oscillating motor passes through the central arc hole. A connecting rod is rotatably connected to the crankshaft. A connecting seat is also provided at the lower end of the mounting base. The end of the connecting rod away from the crankshaft is connected to the connecting seat.

[0010] In one alternative: the drive assembly includes a first oscillating motor, which is mounted at the lower end of the inclined support. The output end of the first oscillating motor is provided with a drive gear that meshes with a rotating shaft gear. The central ring is also provided with a second limiting assembly for limiting the rotation of the rotating shaft gear.

[0011] In one alternative: the second limiting component includes an arc-shaped slide groove, which is located at the lower end of the central ring. A slidable reciprocating column is provided in the arc-shaped slide groove, and a paddle for pushing the reciprocating column is also provided on the rotating shaft gear.

[0012] In one alternative embodiment: the blower assembly includes a motor bracket, which is installed inside a rear grille. A capacitor motor is installed inside the motor bracket, and a fan blade is provided at the output end of the capacitor motor. A front grille is installed on the rear grille, and an air duct is installed on the front grille. The lower end of the rear grille is also provided with a mounting base for connecting to the gear connection end of the rotating shaft.

[0013] In one alternative: a handle is installed on one side of the rotating platform.

[0014] In one alternative embodiment, a rubber anti-slip pad is also attached to the lower end face of the bottom shell.

[0015] In one alternative: the handle is made of artificial leather.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention can achieve a larger oscillation angle, which is more conducive to air circulation: The most significant feature of the super 360° oscillation structure disclosed in the technical solution of the present invention is that when the fan is blowing air, it oscillates, and the air will flow with the wind force, thereby driving the air in the entire space to flow and forming an air circulation. When the oscillation angle is larger, the affected area will also be larger, which will make the air flow speed faster.

[0017] 2. This invention can effectively improve the service life of plastic parts: In the oscillating structure disclosed in the technical solution of this invention, the reciprocating column and rotating shaft gear that affect the oscillation are movable parts. When the rotating shaft gear rotates to the end, the reciprocating column can move, thereby buffering the collision force between the rotating shaft gear, the reciprocating column, and the paddle. In contrast, in similar oscillating structures on the market, the reciprocating column and rotating shaft gear are fixed. When the reset column collides with the reset iron plate, the weight of the fan head will increase the impact force on the reset column, thereby reducing the service life of the reset column.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4 As shown, the super 360-degree circulating fan with a paddle slider structure includes a base shell 1, a first limiting component, a swing component, a drive component, and a blowing component. The lower end face of the base shell 1 is also affixed with a rubber anti-slip pad, which effectively increases the friction at the bottom of the base shell 1, making it more stable during operation. The upper end of the base shell 1 is provided with a mounting base 28, and a rotating middle plate 21 is rotatably connected inside the mounting base 28. Arc-shaped limiting holes 27 are opened on both sides of the mounting base 28. A rotating platform 2 is fixedly connected to the rotating middle plate 21. A handle 5, made of artificial leather, is installed on the side to facilitate the handling of the fan. An inclined bracket 13 is installed on the upper inclined surface of the rotating platform 2. A central ring 20 is provided in the middle of the inclined bracket 13. A bearing 17 is installed in the center of the central ring 20. A rotating shaft gear 11 is installed in the bearing 17. The rotating shaft gear 11 is fixedly connected to the rear mesh cover 3 at the position where the shaft passes through the rotating platform 2. A circuit board 29 is also provided inside the bottom shell 1. The second oscillating motor 22, the rotating middle plate 21, and the capacitor motor 8 are all electrically connected to the circuit board 29.

[0022] In this embodiment, during operation, the swing component and the first limiting component can drive the rotating table 2 to swing back and forth. At the same time, the driving component can drive the blowing component to swing more than 360 degrees during use. When the fan blows air, it swings its head, and the air will flow with the wind force, thereby driving the air in the entire space to flow and forming an air circulation. When the swing angle is larger, the affected area will also be larger, which will make the air flow speed faster.

[0023] In one embodiment, such as Figure 10 and Figure 11As shown, the first limiting component is provided on the rotating middle plate 21 and is used to limit the rotation of the middle plate 21 in cooperation with the arc-shaped limiting hole 27. The first limiting component includes limiting pins 10, which are fixedly connected to the positions on both sides of the rotating middle plate 21. The two limiting pins 10 pass through the arc-shaped limiting hole 27 respectively, and the ends of the limiting pins 10 are fixedly connected to the positions where they pass through the arc-shaped limiting hole 27. The arc-shaped limiting hole 27 can limit the rotation of the rotating table 2 under the combined action of the limiting pins 10 and the limiting hole 30.

[0024] In one embodiment, such as Figures 9-11 As shown, the swing assembly is located inside the rotating plate 21 and is used to drive the rotating plate 21 to swing. The swing assembly includes a second swing head motor 22, which is fixedly connected inside the rotating plate 21. A central arc hole 24 is also provided on one side of the lower end of the mounting base 28. A crankshaft 25 is installed at the position where the output end of the second swing head motor 22 passes through the central arc hole 24. A connecting rod 26 is rotatably connected to the crankshaft 25. A connecting seat 23 is also provided at the lower end of the mounting base 28. The end of the connecting rod 26 away from the crankshaft 25 is connected to the connecting seat 23.

[0025] During operation, the second swing head motor 22 drives the crankshaft 25 to rotate, and the crankshaft 25 drives the connecting rod 26 to move. Since the connecting rod 26 is connected to the connecting seat 23, the connecting rod 26 is restricted by the connecting seat 23. Thus, when the second swing head motor 22 rotates, it can drive the rotating plate 21 to swing back and forth.

[0026] In one embodiment, such as Figures 5-8 As shown, the drive assembly is mounted on the inclined bracket 13 and is used to drive the rotating shaft gear 11 to rotate more than 360 degrees. The drive assembly includes a first oscillating motor 12, which is mounted at the lower end of the inclined bracket 13. The output end of the first oscillating motor 12 is provided with a drive gear 15, which meshes with the rotating shaft gear 11. The central ring 20 is also provided with a second limiting assembly for limiting the rotation of the rotating shaft gear 11. The second limiting assembly has an arc-shaped slide groove 19, which is located at the lower end of the central ring 20. The arc-shaped slide groove 19 contains a slidable reciprocating column 18. The rotating shaft gear 11 is also provided with a paddle 16 for pushing the reciprocating column 18.

[0027] During operation, the first oscillating motor 12 drives the drive gear 15 to rotate, and the drive gear 15 drives the rotating shaft gear 11 to rotate. When the rotating shaft gear 11 rotates, the paddle 16 on the rotating shaft gear 11 pushes the reciprocating column 18 to move in the arc-shaped slide groove 19. When the reciprocating column 18 is pushed by the paddle 16, the rotating shaft gear 11 can rotate a larger angle, thereby achieving a more than 360° oscillation.

[0028] In one embodiment, such as Figure 3 As shown, the blower assembly is mounted on the rear grille 3 and is used to generate airflow. The blower assembly includes a motor bracket 9, which is installed inside the rear grille 3. A capacitor motor 8 is installed inside the motor bracket 9, and a fan blade 7 is provided at the output end of the capacitor motor 8. A front grille 6 is mounted on the rear grille 3, and an air duct 4 is mounted on the front grille 6. The lower end of the rear grille 3 is also provided with a mounting seat 14 for connecting to the connecting end of the rotating shaft gear 11. During operation, the capacitor motor 8 drives the fan blade 7 to rotate, and the high-speed rotation of the fan blade 7 generates airflow. At the same time, the air duct 4 and the front grille 6 can guide the generated airflow.

[0029] In summary: During operation, the capacitor motor 8 drives the fan blades 7 to rotate, generating wind power. Simultaneously, the first oscillating motor 12 drives the drive gear 15 to rotate, which in turn drives the rotating shaft gear 11 to rotate. When the rotating shaft gear 11 is driven clockwise by the drive gear 15, the paddle 16 follows the clockwise rotation of the rotating shaft gear 11. When the paddle 16 touches the reciprocating column 18, the reciprocating column 18 slides in the limiting arc-shaped slide groove 19 until it reaches the rightmost end of the arc-shaped slide groove 19, where its movement is blocked. At this point, the rotating shaft gear 11 stops rotating, and the drive gear 15 is also forced to stop rotating. At this point, the internal mechanism of the first oscillating motor 12 allows the motor to automatically reverse. After reversing, the drive gear 15 drives the rotating shaft gear 11 to rotate counterclockwise. The rotating shaft gear 11 rotates about 360 degrees. When the paddle 16 touches the reciprocating column 18, the drive gear 15 continues to rotate counterclockwise. At this time, the paddle 16 pushes the reciprocating column 18 to slide in the arc-shaped slide groove 19 until the reciprocating column 18 reaches the leftmost end of the arc-shaped slide groove 19, where the movement is blocked. At this time, both the drive gear 15 and the reciprocating column 18 stop moving, and the rotating shaft gear 11 is also forced to stop rotating. The first oscillating motor 12 reverses again and repeats the above cycle, which can rotate more than 360 degrees.

[0030] At the same time, the length of the arc-shaped slide 19 can be set to determine the number of angles exceeding 360 degrees, such as 380 degrees, 400 degrees, etc., all of which can be achieved.

[0031] Meanwhile, during operation, the second swing head motor 22 drives the crankshaft 25 to rotate, and the crankshaft 25 drives the connecting rod 26 to move. Since the connecting rod 26 is connected to the connecting seat 23, the connecting rod 26 is restricted by the connecting seat 23. Thus, when the second swing head motor 22 rotates, it can drive the rotating plate 21 to swing back and forth.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
