Description

Technical Field

[0001] This utility model relates to the field of ceiling-mounted fans, specifically an adjustable multi-functional ceiling-mounted fan. Background Technology

[0002] Adjustable ceiling fans are an advanced type of ceiling fan, also installed above the building ceiling, serving as a key piece of equipment for ventilation. Their construction expands upon the basic components of traditional ceiling fans. In addition to the essential motor, blades, casing, and bracket, a series of adjustment devices are added. The motor remains the core drive, rotating the blades to create airflow. The blades not only have a finely designed aerodynamic shape but also feature special angle adjustment structures at the connection points, such as rotatable joints and graduated adjustment rods, allowing for precise changes in the blade tilt angle to control the vertical angle of the airflow and adapt to the ventilation needs of spaces at different heights.

[0003] Announcement No. CN220287562U discloses a heat fan with adjustable angle, relating to the field of heater technology. This adjustable heat fan includes a fan base with an arc-shaped fixing frame fixedly connected to the top. A rotating shaft is rotatably connected inside the arc-shaped fixing frame, and a spherical reflector is fixedly connected to the surface of the rotating shaft. Currently, most adjustable ceiling-mounted fans still rely on purely manual operation for these multi-dimensional angle adjustments. Operators must first overcome the challenges of working at height. On narrow and often poorly lit high platforms, relying solely on touch and sight, laboriously turning adjusting nuts and inserting / removing positioning pins to rotate the fan body angle is extremely time-consuming. In multi-story industrial plants, where multiple fans are distributed on each floor, a single comprehensive adjustment can take several hours, severely impacting production rhythm. Furthermore, it is extremely physically demanding for operators, easily leading to fatigue risks. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 The present invention provides a technical solution: an adjustable multi-functional ceiling fan, including a top base 1, a protective shell 2 fixedly connected to the bottom of the top base 1, a first motor 3 disposed inside the protective shell 2, a rotating shaft 4 fixedly connected to the output end of the first motor 3, a fan 5 fixedly connected to the lower end of the rotating shaft 4, a rotating mechanism 6 disposed above the first motor 3, and a pulling mechanism 7 disposed between the rotating mechanism 6 and the first motor 3;

[0023] The rotating mechanism 6 includes a first support plate 601 fixedly connected to the inner wall of the protective shell 2. A second motor 602 is fixedly connected to the upper surface of the first support plate 601. A first gear 603 is fixedly connected to the output end of the second motor 602. A second gear 604 is meshed with the outer side of the first gear 603. A first rotating cylinder 605 is fixedly connected inside the second gear 604. The first rotating cylinder 605 is rotatably connected to the top seat 1, allowing the first rotating cylinder 605 to rotate without moving up and down. A first hole 606 is provided in the middle of the first support plate 601. A first rotating rod 607 is fixedly connected to the lower outer side of the first rotating cylinder 605. A first groove 608 is provided inside the first rotating rod 607. A second rotating rod 609 is provided on the inner side of the first groove 608. The inner side of the first groove 608 fits against the outer side of the second rotating rod 609, and the second rotating rod 609 has a cuboid shape, so that the second rotating rod 609 will not rotate or wobble when it moves inside the first groove 608. A first guide groove 610 is provided inside the lower surface of the first support plate 601. A first guide rod 611 is fixedly connected to the second rotating rod 609 on the inner side of the first guide groove 610. The first guide groove 610 has a vortex shape, and the first guide groove 610 and the first guide rod 611 are fitted with a clearance fit, so that the first guide rod 611 can move inward or outward when it rotates inside the first guide groove 610.

[0024] The pulling mechanism 7 includes a first connecting rod 701 disposed inside the first rotating cylinder 605. A second groove 702 is disposed below the first connecting rod 701. A connecting block 703 is disposed inside the second groove 702. The connecting block 703 has a spherical shape, and its outer surface fits against the inner surface of the second groove 702, preventing it from wobbling when rotating inside the second groove 702. A second connecting rod 704 is fixedly connected to the lower end of the connecting block 703. A sliding groove 705 is disposed inside the second connecting rod 704, and a slider 706 is disposed inside the sliding groove 705. A third connecting rod 707 is fixedly connected to the lower end of the second rotating rod 609. The third connecting rod 707 and the slider 706... The connection method of 06 is a hinge connection. The first paddle 708 is fixedly connected to the lower inner side of the first support plate 601, and the second paddle 709 is fixedly connected to the upper surface of the first rotating rod 607. The width of the slider 706 at the end near the central axis of the second connecting rod 704 is greater than the width of the end of the slider 706 away from the central axis of the second connecting rod 704. The outer side of the slider 706 is in contact with the inner side of the slide groove 705, so that the inner side of the slider 706 will not move out of the inner side of the slide groove 705 when it moves. The first paddle 708 is circularly and equidistantly distributed below the first support plate 601, so that the second paddle 709 can contact the first paddle 708 when it rotates. The connection method between the second connecting rod 704 and the first motor 3 is a fixed connection.

[0025] When angle adjustment is required, the second motor 602 is started to drive the first gear 603 and the second gear 604 to rotate, causing the first rotating cylinder 605, the first rotating rod 607, and the second rotating rod 609 to rotate. This causes the first guide rod 611 to rotate inside the first guide groove 610. Because the first guide groove 610 has a vortex-shaped structure and the first guide groove 610 and the first guide rod 611 are in a clearance fit, the first guide rod 611 moves outward when rotating inside the first guide groove 610, pulling the second connecting rod 704 outward. This causes the slider 706 and the second connecting rod 704 to swing and rotate, causing the first motor 3, the rotating shaft 4, and the fan 5 to swing and rotate, thus changing the angle of the fan 5. No manual adjustment is required, making the adjustment process simple.

[0026] When the first rotating rod 607 rotates, it drives the second paddle 709 to rotate. Because the first paddle 708 is circularly and equidistantly distributed below the first support plate 601, the second paddle 709 continuously contacts the first paddle 708. This causes the first rotating rod 607, the third connecting rod 707, the second rotating rod 609, the slider 706, the second connecting rod 704, and the first motor 3 to vibrate slightly, allowing dust on the fan 5 to fall off.
