Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a fan drive head with a control module radially integrated. Background Technology

[0002] Electric fans are widely used in homes, offices, shopping malls and other places. They are usually equipped with a basic structure including a motor, fan blades, protective cover, and control module.

[0003] Floor fans, as one of the most common types of household fans, typically feature large fan blades, a support rod, and a wide base to prevent the fan from tipping over. They also usually have an oscillation function for multi-angle airflow. Traditional floor fans typically place the control components on the base or the support rod. However, placing the control components on the base requires the user to bend over to operate the fan, which is inconvenient; while placing them on the support rod exposes the control module, disrupting the streamlined structure of the support rod and affecting the overall aesthetics of the fan. Furthermore, the control components occupy the cross-sectional area of ​​the support rod's interior, limiting the miniaturization of the rod's diameter. Additionally, when the fan oscillates horizontally, the cable at the base of the support rod is subjected to cyclic torsional stress, leading to wire bending fatigue and wear, thus affecting the fan's lifespan. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a fan drive head with a radially integrated control module, which facilitates user control of the fan and improves its lifespan.

[0005] The solution adopted by this utility model to solve its technical problem is: a fan drive head with a control module radially integrated, including a fan head housing, wherein a drive component and a PCB control component are disposed inside the fan head housing; The fan head housing includes a cylindrical motor housing, with a front cover and a protective cover fixedly connected to both ends of the cylindrical motor housing, respectively; the drive assembly is fixed inside the cylindrical motor housing, with its output end facing the front cover, and its power output shaft passing through the center of the front cover to drive the fan impeller to rotate; the PCB control assembly includes a PCB bracket and a PCB board, with the PCB bracket fixedly connected to the cylindrical motor housing and located on top of the drive assembly, and the PCB board fixed to the bottom surface of the PCB bracket; The drive assembly includes a support frame and a motor. The support frame is fixed inside a cylindrical motor housing, and the motor is fixed inside the support frame.

[0006] Furthermore, a lampshade is fixedly connected inside the cylindrical motor housing, and the lampshade is located on the top of the PCB board and electrically connected to the PCB board.

[0007] Furthermore, a radial through hole is formed at the bottom of the cylindrical motor housing; a control key is provided at the top of the cylindrical motor housing, the control key is electrically connected to the PCB board, and the control key includes a head swing button, a mode button and a timer button.

[0008] Furthermore, the support frame includes a central round head and symmetrically distributed fixing parts on the central round head. The fixing parts are connected to the inner wall of the housing. The output shaft of the motor passes through the central round head, and the central round head is fixedly connected to the front cover.

[0009] In summary, the beneficial effects of this utility model are as follows: 1. This application integrates the oscillation head, mode, and timer buttons on the top of the fan drive head, making it convenient for users to use and control the fan; 2. The control module PCB board and drive components are radially layered inside the cylindrical motor housing, which can make the most of the space in the fan head housing, so as to achieve the purpose of the head operating the fan while reducing the volume space occupied by the fan head housing. 3. The control module PCB board and control buttons of this application are all located inside the fan head housing, and all control cables are fixed inside the fan head housing, eliminating the relative movement of the cables when the support rod swings, and improving the service life of the fan.

[0016] like Figures 1 to 2 As shown, a fan drive head with a radially integrated control module includes a fan head housing 1, and a drive component and a PCB control component are disposed inside the fan head housing 1.

[0017] like Figure 1 As shown, the fan head housing 1 in this embodiment is a cylindrical motor housing 11. A front cover 12 and a protective cover 13 are fixedly connected to both ends of the cylindrical motor housing 11. This design provides mechanical support for the components within the housing. The drive assembly is fixed inside the cylindrical motor housing 11, with its output end facing the front cover 12. Its power output shaft passes through the center of the front cover 12 and is used to drive the fan impeller to rotate. The PCB control assembly includes a PCB bracket 31 and a PCB board 32. The PCB bracket 31 is fixedly connected to the cylindrical motor housing 11 and located on top of the drive assembly, while the PCB board 32 is fixed to the bottom surface of the PCB bracket 31.

[0018] A radial through hole 5 is provided at the bottom of the cylindrical motor housing 11 for connecting the support rod. A control key is provided at the top of the cylindrical motor housing 11. The control key is electrically connected to the PCB board 32. The control key includes a light-off button, an oscillation button, a mode button, and a timer button. Users can adjust the fan's working mode by pressing the various buttons on the fan drive head.

[0019] This embodiment integrates the control component—PCB board 32—and operation buttons onto the fan drive head, allowing users to conveniently adjust the operating mode from the height of the fan head without bending over or moving to the fan base. This ergonomic design, with an operating height closer to the range of motion of an adult's upper limbs when standing naturally, enhances human-computer interaction convenience and is particularly suitable for vertical fans or high-positioned applications.

[0020] In addition, the PCB control and drive components adopt a radial layered design, which makes the structure of the fan head more compact, reduces the overall size and weight of the fan, and optimizes the utilization of internal space, allowing the fan head to achieve a slimmer shape while maintaining high performance.

[0021] like Figure 2 As shown, a lampshade 4 is fixedly connected inside the cylindrical motor housing 11. The lampshade 4 is located on the top of the PCB board 32 and is electrically connected to the PCB board 32. In this embodiment, an LED light is provided inside the lampshade 4. The LED light can perform multiple lighting modes to facilitate the user to confirm the working status of the fan.

[0022] The drive assembly in this embodiment includes a support frame 21 and a motor 22. The support frame 21 is fixed inside the cylindrical motor housing 11, and the motor 22 is fixed inside the support frame 21 to reduce vibration.

[0023] like Figure 1 As shown, the support frame 21 includes a central round head and symmetrically distributed fixing parts on the central round head. The fixing parts are connected to the inner wall of the housing. The symmetrically distributed fixing parts are rigidly connected to the inner wall of the housing to ensure that the motor 22 has no deviation or vibration when running at high speed. The output shaft of the motor 22 passes through the central round head, and the central round head is fixedly connected to the front cover 12.

[0024] The installation method of the fan drive head in this embodiment is as follows: 1. Fix the motor 22 to the support frame 21 by screws to form a drive assembly; 2. Fix the PCB board 32 to the PCB bracket 31 by screws to form a PCB control assembly; 3. Secure the lamp cover 4 to the cylindrical motor housing 11; 4. Assemble the installed drive assembly and PCB control assembly into the cylindrical motor housing 11; 5. Lock the motor front cover 12 to the front end of the cylindrical motor housing 11 by screws; 6. Fix the cover 13 to the rear end of the cylindrical motor housing 11 by hooks.

[0025] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
