Description

Technical Field

[0001] This utility model relates to the field of electric fans, specifically to a synchronous motor oscillation mechanism for a floor-standing commercial fan. Background Technology

[0002] Commercial fans are electric fans primarily used in commercial offices or similar environments. They typically feature streamlined blades and utilize the positive pressure axial flow principle to evenly distribute air, achieving ventilation and cooling. To meet the ventilation and cooling needs of larger spaces, commercial fans usually have a large airflow output. Simultaneously, to create a quiet and comfortable office environment, commercial fans generally use optimized motors and blades, producing less noise during operation. Most commercial fans have multiple speed settings and adjustable airflow angles to meet different needs. Commercial fans play a crucial role in commercial environments, not only improving the comfort of employees and customers but also enhancing indoor air quality and increasing work efficiency. Commercial fans are mostly floor-standing, wall-mounted, or tabletop models, with designs that blend seamlessly into the commercial environment.

[0003] Common floor-standing commercial fans are suitable for various floor environments and can be placed in office corners, meeting rooms, etc., achieving large-area airflow by adjusting the height and angle. However, most floor-standing commercial fans have the motor installed at the rear of the fan head, making the fan head relatively thick and taking up a lot of space. This may appear obtrusive in spaces with limited space, and also affect the overall layout of the space and ease of use. Summary of the Invention

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a synchronous motor oscillation mechanism for a floor-standing commercial fan. Its structure is simple and reasonable, and it is easy and quick to assemble. It is installed at the bottom of the fan head to reduce the space occupied by the fan, and its design is simple and stable.

[0005] To address the problems existing in the background technology, this utility model adopts the following technical solution: a synchronous motor oscillation mechanism for a floor-standing commercial fan, comprising a fan head housing, a mounting panel, a motor, a central rotating shaft, a synchronous motor bracket, a synchronous motor, a first oscillation rotating arm, a second oscillation rotating arm, and a central fixed shaft. The motor is fixed inside the fan head housing via the mounting panel. The central rotating shaft and the synchronous motor bracket are respectively fixed to the plane at the bottom of the motor. The synchronous motor is fixed on the synchronous motor bracket. One end of the first oscillation rotating arm is rotatably connected perpendicularly to the rotor at the bottom of the synchronous motor, and the other end is rotatably connected perpendicularly to one end of the second oscillation rotating arm. The bottom of the central rotating shaft is rotatably connected to the top of the central fixed shaft. A positioning seat is also provided on one side of the central fixed shaft, and the other end of the second oscillation rotating arm is rotatably connected perpendicularly to the positioning seat.

[0006] The working principle of this utility model is as follows: The rotor of the synchronous motor drives the first oscillating rotating arm to rotate, which in turn drives the second oscillating rotating arm to rotate. Since the second oscillating rotating arm is fixed on the positioning seat, and since the synchronous motor is fixed to the bottom of the motor through the synchronous motor bracket, the rotor of the synchronous motor drives the entire fan head to oscillate left and right while rotating. One rotation of the rotor of the synchronous motor causes the fan head to rotate back and forth for one stroke. When the first oscillating rotating arm rotates to overlap with the second oscillating rotating arm to form the shortest straight line from the positioning seat, the fan head is at the leftmost or rightmost position. When the first oscillating rotating arm rotates to form the longest straight line from the positioning seat with the second oscillating rotating arm, the fan head is at the rightmost or leftmost position, thus realizing the automatic left and right oscillation function of the synchronous motor installed at the bottom of the fan head.

[0007] By adopting the above technical solution, the oscillating mechanism of this utility model is installed at the bottom of the fan head, making the fan head thinner, lighter, more refined, and modern in appearance, thus better integrating into various home and office environments and enhancing overall aesthetics. It occupies less space during storage and use, making it easy to store and store, especially suitable for limited space such as office corners and meeting rooms. It is also easy to move and can be quickly transferred to different rooms or locations as needed. The thinner fan head allows for more flexible angle adjustment, easily achieving multi-angle airflow in all directions and precisely controlling the airflow direction to meet the needs of different users in different scenarios. Simultaneously, the thinner fan head has a relatively shorter airflow path, resulting in less airflow obstruction, effectively reducing wind resistance and noise, and improving airflow efficiency, thereby enhancing the fan's airflow capacity. Due to the reduced wind resistance, the energy consumption required by the motor to drive the fan rotation is also reduced, achieving energy-saving effects, especially during long-term use, saving users on electricity bills.

[0008] Furthermore, the bottom of the central fixed shaft is fixedly connected to the pitch angle adjustment seat, and the pitch angle adjustment seat is rotatably connected to the fuselage.

[0009] After adopting the above technical solution, the pitch angle of the fan can be adjusted according to the user's needs, easily achieving multi-angle air delivery in all directions.

[0010] Furthermore, an oscillation switch is provided on one side of the fan head housing, and the oscillation switch is electrically connected to the synchronous motor.

[0011] With the above technical solution, this utility model can control the fan to oscillate or blow directly at a fixed point by the oscillation switch set on one side of the fan head housing, or it can be controlled by a remote control or mobile phone.

[0012] Furthermore, the synchronous motor bracket has a Z-shaped cross-section, its top beam is fixed to the plane at the bottom of the motor, and the synchronous motor is fixed on its bottom beam.

[0013] By adopting the above technical solution, the "Z"-shaped synchronous motor bracket set in this utility model enables the oscillating mechanism to be installed at the bottom of the motor, which can enhance the stability of the synchronous motor installation and facilitate the positioning and installation of the oscillating mechanism. It has the beneficial effects of good structural stability and simple and quick assembly. Attached Figure Description

One end of the first oscillation rotating arm 7 is rotatably connected perpendicularly to the rotor at the bottom of the synchronous motor 6, and the other end is rotatably connected perpendicularly to one end of the second oscillation rotating arm 8. The bottom of the central rotating shaft 4 is rotatably connected to the top of the central fixed shaft 9. A positioning seat 91 is also provided on one side of the central fixed shaft 9. The other end of the second oscillation rotating arm 8 is rotatably connected perpendicularly to the positioning seat 91. The oscillating mechanism in this specific embodiment is installed at the bottom of the fan head, making the fan head thinner, lighter, and more refined, with a modern and simple feel. It blends better into various home and office environments, enhancing overall aesthetics. It occupies less space during storage and use, making it easy to store and store, especially suitable for limited office corners and meeting rooms. It is also easy to move, allowing for quick relocation to different rooms or locations as needed. The thinner fan head offers greater flexibility in angle adjustment, easily achieving multi-angle airflow in all directions and precisely controlling the airflow direction to meet the needs of different users in different scenarios. Simultaneously, the thinner fan head has a relatively shorter airflow path, with less obstruction to the airflow, effectively reducing wind resistance and noise, improving airflow efficiency, and thus enhancing the fan's airflow capacity. Due to the reduced wind resistance, the energy consumption of the motor to drive the fan rotation is also reduced, achieving energy-saving effects, especially during long-term use, saving users on electricity bills.

[0030] In this specific embodiment, the rotor of the synchronous motor 6 drives the first oscillating rotating arm 7 to rotate, and the first oscillating rotating arm 7 then drives the second oscillating rotating arm 8 to rotate. Since the second oscillating rotating arm 8 is fixed on the positioning seat 91, and since the synchronous motor 6 is fixed to the bottom of the motor 3 through the synchronous motor bracket 5, the rotor of the synchronous motor 6 drives the entire fan head to oscillate left and right while rotating. One rotation of the rotor of the synchronous motor causes the fan head to rotate back and forth for one stroke. When the first oscillating rotating arm 7 rotates to overlap with the second oscillating rotating arm 8 to form the shortest straight line from the positioning seat 91, the fan head is at the leftmost or rightmost position. When the first oscillating rotating arm 7 rotates to form the longest straight line from the positioning seat 91 with the second oscillating rotating arm 8, the fan head is at the rightmost or leftmost position, thereby realizing the automatic left and right oscillating function of the synchronous motor 9 installed at the bottom of the fan head.

[0031] In this specific embodiment, the bottom of the central fixed shaft 9 is fixedly connected to the pitch angle adjustment seat 10, and the pitch angle adjustment seat 10 is rotatably connected to the body 11. This specific embodiment allows the user to adjust the fan's pitch angle according to their needs, easily achieving multi-angle airflow in all directions.

[0032] In this specific embodiment, an oscillation switch 12 is provided on one side of the fan head housing 1, and the oscillation switch 12 is electrically connected to the synchronous motor 6. In this specific embodiment, the fan can be controlled to oscillate or blow directly at a fixed point using the oscillation switch 12 provided on one side of the fan head housing 1, or it can be controlled by a remote control or mobile phone.

[0033] In this specific embodiment, the synchronous motor bracket 5 has a Z-shaped cross-section, with its top beam fixed to the plane at the bottom of the motor 3 and the synchronous motor 6 fixed on its bottom beam. The Z-shaped synchronous motor bracket 5 provided in this specific embodiment enables the oscillating mechanism to be installed at the bottom of the motor 3, which can enhance the stability of the synchronous motor 6 installation and facilitate the positioning and installation of the oscillating mechanism. It has the beneficial effects of good structural stability and simple and quick assembly.
