Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model relates to a multi-angle air supply ceiling fan, such as... Figures 1 to 4 As shown, the device includes a fan motor 3, an impeller 4, and a connecting sleeve 1 for connecting the suspension rod 99. The connecting sleeve 1 is located above the fan motor 3. The fan motor 3 has a fan motor shaft 31, and the impeller 4 is coaxially mounted on the fan motor shaft 31. The fan motor shaft 31 can be a D-shaped shaft. A D-shaped hole is formed at the central axis of the impeller 4. The aforementioned D-shaped hole is adapted to connect the fan motor shaft 31, so that the fan motor 3 can drive the impeller 4 to rotate.

[0022] like Figures 1 to 5 As shown, the multi-angle ceiling fan of this utility model also includes an oscillation mechanism 2. The oscillation mechanism 2 includes a hanging frame 24 and a cradle 28. The upper end of the hanging frame 24 is horizontally rotatably connected to the connecting sleeve 1. In other words, the hanging frame 24 can rotate around an axis perpendicular to the horizontal plane. The lower end of the hanging frame 24 is oscillatingly connected to the upper end of the cradle 28 through a hinge shaft 241. The hinge shaft 241 is horizontally set, that is, the oscillation axis of the cradle 28 relative to the hanging frame 24 is in the horizontal plane. The fan motor 3 includes a fan motor housing 30, which is mounted on the cradle 28 by corresponding screws. The fan motor shaft 31 passes through the cradle 28. Figure 8As shown, a clearance hole is formed at the bottom of the cradle 28, through which the fan motor shaft 31 passes, as... Figure 1 and Figure 3 As shown, impeller 4 is located below cradle 28. Figure 4 and Figure 5 As shown, the oscillating mechanism 2 includes a rotary drive motor 21 and a swing drive motor 25 for driving the cradle 28 to swing. The rotary drive motor 21 and the swing drive motor 25 are mounted on the hanger 24 (that is, the housings of the rotary drive motor 21 and the swing drive motor 25 are respectively connected to the hanger 24 by fasteners). The rotary drive motor 21 drives the hanger 24 to rotate. The oscillating mechanism 2 includes a crank 26 and a connecting rod 27. One end of the crank 26 is connected to the output shaft of the swing drive motor 25. For example, the crank 26 and the output shaft of the swing drive motor 25 are fixed relative to each other by a set screw. The other end of the crank 26 is hinged to one end of the connecting rod 27, and the other end of the connecting rod 27 is hinged to the cradle 28. Moreover, the hinge point between the connecting rod 27 and the cradle 28 is offset to one side of the hinge shaft 241.

[0023] The working principle of this ceiling fan is briefly explained below: Figures 1 to 5As shown, a hanging rod 99 is installed on the indoor ceiling, and a connecting sleeve 1 connects to the hanging rod 99, so that the ceiling fan is located on the lower side of the indoor ceiling. The fan motor 3 drives the impeller 4 to rotate, and the impeller 4 blows air downwards. The output shaft of the oscillating drive motor 25 drives the crank 26 to rotate, and the crank 26 drives the connecting rod 27 to swing back and forth. The connecting rod 27 pushes and pulls the cradle 28, so that the cradle 28 swings back and forth around the hinge shaft 241. When the central axis of the impeller 4 swings to a position perpendicular to the horizontal plane, the impeller 4 blows air directly downwards. When the central axis of the impeller 4 forms an acute angle with the horizontal plane, the impeller... 4. The fan motor 3 and impeller 4 are relatively biased towards the outer side. Simultaneously, the rotary drive motor 21 drives the hanging bracket 24 to rotate. Since the fan motor housing 30 is mounted on the cradle 28 with corresponding screws, the fan motor 3 and impeller 4 rotate horizontally simultaneously. This makes the air delivery range of the impeller 4 approximately an upright cone shape (including the interior of the cone). Compared to existing technologies, this multi-angle air delivery ceiling fan has a larger air delivery range. When applied in a classroom, it can provide effective ventilation for more students. Because the overall rotation and oscillation of the fan motor 3 and impeller 4 are achieved independently by the rotary drive motor 21 and the oscillating drive motor 25, in practical applications, the rotary drive motor 21 can be stopped in certain situations to reduce the air delivery range. This allows for more concentrated air delivery to people in specific locations, facilitating flexible air delivery. Since the oscillating drive motor 25 drives the fan motor 3 and impeller 4 to oscillate back and forth as a whole through the crank 26 and connecting rod 27, that is, to achieve reciprocating oscillation through a mechanical structure, the oscillating drive motor 25 can rotate in one direction. This avoids the need to use a stepper motor or servo motor for the oscillating drive motor 25, which simplifies the control circuit of the oscillating drive motor 25 and helps to reduce costs. Since the rotary drive motor 21 and the oscillating drive motor 25 are mounted on the hanger 24, and the fan motor housing 30 is mounted on the cradle 28 with corresponding screws, the vibration generated by the operation of the fan motor 3 is prevented from directly affecting the rotary drive motor 21 and the oscillating drive motor 25.

[0024] For example, the first synchronous pulley can be fixed relative to the connecting sleeve 1, and the second synchronous pulley can be coaxially mounted on the output shaft of the rotary drive motor 21. The first and second synchronous pulleys are connected by a synchronous belt. For example, the output shaft of the rotary drive motor 21 is coaxially fixed relative to the connecting sleeve 1, that is, the output shaft of the rotary drive motor 21 is vertically set, and the outer casing of the rotary drive motor 21 is fixed relative to the hanger 24.

[0025] In some embodiments, such as Figures 3 to 5As shown, the oscillating mechanism 2 includes a rotating gear 22 and a gear disk 23. The gear disk 23 is coaxially connected to the connecting sleeve 1. The rotating gear 22 and the gear disk 23 are externally meshed. The rotating drive motor 21 drives the rotating gear 22. Specifically, the rotating gear 22 is coaxially mounted on the output shaft of the rotating drive motor 21. Thus, the rotating drive motor 21 drives the rotating gear 22 to rotate, and the rotating gear 22 drives the gear disk 23 to rotate. Since the gear disk 23 is coaxially connected to the connecting sleeve 1, and the rotating drive motor 21 is mounted on the hanger 24, the hanger 24 can rotate. Through the above arrangement, the output shaft of the rotating drive motor 21 is prevented from bearing the weight of the fan motor 3 and the impeller 4.

[0026] Furthermore, such as Figure 8 As shown, the hanger 24 includes a hanger top plate 2401, with both ends of the hanger top plate 2401 bent downwards to form hanger side plates 2402, meaning there are two hanger side plates 2402. Hinges 241 are formed at the lower ends of the hanger side plates 2402, and the hinges 241 can be welded to the hanger side plates 2402. The cradle 28 includes a cradle bottom plate 2801, with both ends of the cradle bottom plate 2801 bent upwards to form cradle side plates 2802. The hanger side plates 2402 are located inside the corresponding cradle side plates 2802. The hinges 241 pass through the corresponding cradle side plates 2802. The rotation drive motor 21 and the swing drive motor 25 are located inside the hanger 24. Figure 5 As shown, the rotary drive motor 21 and the oscillating drive motor 25 are located between the two side plates 2402 of the ceiling fan, which helps to make the ceiling fan compact. Figure 4 and Figure 5 As shown, the fan motor housing 30 is located between the two cradle side plates 2802. Figure 5 and Figure 8 As shown, the hanger 24 is also provided with a crossbeam 8, which is located between two hanger side plates 2402. The two ends of the crossbeam 8 are connected to the hanger side plates 2402 by fasteners. The fan motor housing 30 is located on the lower side of the crossbeam 8, and the rotary drive motor 21 and the oscillating drive motor 25 are located on the upper side of the crossbeam 8. By providing the crossbeam 8, it is beneficial to increase the structural rigidity of the hanger 24.

[0027] Furthermore, such as Figures 1 to 3As shown, the ceiling fan of this utility model also includes a dust cover 51 and a movable spherical shell 52. A rotary drive motor 21, a rotary gear 22, a gear disc 23, a hanging bracket 24, a swing drive motor 25, and a crank 26 are all located inside the dust cover 51. The upper part of the connecting rod 27 is also located inside the dust cover 51. The upper end of the dust cover 51 is installed on the connecting sleeve 1, thus preventing dust from easily accumulating on the oscillation mechanism 2 and preventing dust and debris from affecting the operation of the oscillation mechanism 2. The upper part of the movable spherical shell 52 is located inside the lower end of the dust cover 51. The cradle 28 and the fan motor housing 30 are housed inside the movable spherical shell 52, preventing dust accumulation on them. The cradle 28 and the movable spherical shell 52 are fixedly connected. The fan motor shaft 31 extends downward through the movable spherical shell 52, meaning the movable spherical shell 52 is approximately spherical in shape and has a through-type structure. The hinge shaft 241 is approximately located on the diameter of the movable spherical shell 52, allowing it to swing and rotate with the cradle 28. When the movable spherical shell 52 swings with the cradle 28, its approximately spherical shape prevents interference and collision between it and the dust cover 51.

[0028] Furthermore, such as Figure 3 and Figure 6 As shown, the connecting sleeve 1 is provided with a shock-absorbing inner sleeve 11 for coaxially inserting the lifting rod 99. The shock-absorbing inner sleeve 11 is adapted to be disposed in the connecting sleeve 1. The connecting sleeve 1 has a pin hole 101, which passes through the shock-absorbing inner sleeve 11. Thus, the lower end of the lifting rod 99 can be coaxially inserted into the shock-absorbing inner sleeve 11. Then, a pin is inserted into the pin hole 101 along the radius of the connecting sleeve 1. The pin passes through the shock-absorbing inner sleeve 11 and the lifting rod 99, thereby preventing the lifting rod 99 and the connecting sleeve 1 from moving up and down relative to each other and moving radially relative to each other. The shock-absorbing inner sleeve 11 can be made of rubber. When the connecting sleeve 1 vibrates (or shakes) in the horizontal direction, the shock-absorbing inner sleeve 11 can absorb the vibration and reduce the vibration of the lifting rod 99 because it is disposed between the connecting sleeve 1 and the lifting rod 99.

[0029] like Figure 6 As shown, a flange 102 is formed on the lower outer part of the connecting sleeve 1, as... Figure 5 As shown, a mounting plate 231 is formed at the upper end of the toothed disc 23, as... Figure 3 As shown, mounting plate 231 and flange 102 are coaxially connected by corresponding screws. Connecting sleeve 1 is coaxially rotatably connected to hanger shaft 6 via bearing 7. The upper part of hanger shaft 6 is located inside connecting sleeve 1. A shaft elastic retaining ring is provided at the upper end of hanger shaft 6, located above bearing 7. An inner flange is formed at the lower end of connecting sleeve 1, supporting the outer ring of bearing 7. The upper end of dust cover 51 is connected to flange 102 by corresponding screws. Connecting sleeve 1 passes through the top of dust cover 51. Hanger shaft 6 is adapted to pass through hanger top plate 2401. Figure 6As shown, a hanging plate 61 is formed at the lower end of the hanging shaft 6, as... Figure 3 As shown, the mounting plate 61 rests against the lower side of the top plate 2401 of the hanger, so the hanging shaft 6 can lift the hanger 24, as... Figure 6 As shown, the hanging plate 61 has a positioning notch 601, and the top plate 2401 of the hanger is equipped with positioning screws. These positioning screws are engaged in the positioning notch 601, which prevents the hanger shaft 6 from rotating relative to the hanger 24. In other words, the hanger 24 is rotatably connected to the connecting sleeve 1 through the hanger shaft 6. Figure 3 As shown, a spacer 29 is provided between the top plate 2401 of the hanger and the lower end face of the inner ring of the bearing 7. (As indicated...) Figure 3 and Figure 7 As shown, the cradle base plate 2801 is mounted on the inner bottom of the movable spherical shell 52 by corresponding screws.
