Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a circulating ceiling fan that is easy to assemble and disassemble and can rotate 360°. Background Technology

[0002] A ceiling fan is an electric fan fixed to the ceiling. It is driven by an electric motor to rotate multiple blades, thus stirring the air and creating airflow to achieve cooling and ventilation. Ceiling fans are typically installed on the ceilings of various indoor spaces such as homes, offices, shops, and restaurants. Due to their height, they can cover a large area and provide comprehensive air circulation. The design and function of ceiling fans vary depending on the manufacturer and intended use, but most ceiling fans share some common features. They usually have a decorative casing or cover to protect the motor and blades, while also enhancing the aesthetics of the interior design. The number and shape of the blades also vary, affecting the airflow and volume produced. Some ceiling fans are also equipped with lighting units, providing illumination and further enhancing the interior décor.

[0003] However, current ceiling fans can only direct airflow directly downwards from multiple blades. Because the blades are oriented in a fixed direction, the area covered by the airflow is relatively small, making it impossible to reach every corner of the room and hindering rapid air circulation. Furthermore, current ceiling fans are inconvenient to assemble and disassemble, causing inconvenience for daily cleaning and maintenance. Therefore, it is necessary to research a solution to these problems. Utility Model Content

Furthermore, a positioning post 103 extends from the lower half-groove 102.

[0042] The multiple fan heads 20 are arranged at intervals around the circumference of the hanger 10. Specifically, each fan head 20 includes a connecting arm 21, a housing 22, a drive mechanism 23, a main motor 24, and an impeller 25. The inner end of the connecting arm 21 is detachably fixed to the hanger 10, and the outer end of the connecting arm 21 has a first inclined surface 211. The first inclined surface 211 faces outward and extends vertically at an incline. The top side of the housing 22 is rotatably mounted on the first inclined surface 211. The housing 22 has a receiving cavity 221. The top of the cover 22 has an air inlet slot 222, which communicates with the accommodating cavity 221. The bottom of the cover 22 has an air outlet slot 223, which communicates with the accommodating cavity 221. The drive mechanism 23 is mounted on the connecting arm 21 and drives the cover 22 to rotate. The main motor 24 is fixed inside the accommodating cavity 221. The impeller 25 is fixed on the output shaft of the main motor 24 and located in the accommodating cavity 221. The impeller 25 is driven to rotate by the main motor 24 and is located between the air inlet slot 222 and the air outlet slot 223. Specifically:

[0043] The inner end of the connecting arm 21 is sandwiched between the main body 11 and the lower cover 12, and is housed in the upper half-groove 101 and the lower half-groove 102. A positioning hole 212 is provided on the inner end of the connecting arm 21, into which the positioning pin 103 is inserted for positioning. The outer end of the connecting arm 21 has a mounting cavity 213, and a mounting hole 214 is provided on the first inclined surface 211, communicating with the mounting cavity 213. Furthermore, the connecting arm 21 is formed by splicing an upper half-shell 215 and a lower half-shell 216 together.

[0044] The top side of the cover 22 has a second inclined surface 224, which is directly opposite to the first inclined surface 211, and a connecting ring 225 extends from the second inclined surface 224.

[0045] The drive mechanism 23 is disposed in the mounting cavity 213, and the connecting ring 225 extends into the mounting hole 214 and is connected to the drive mechanism 23. Specifically, the drive mechanism 23 includes a driven gear 231, a driving gear 232, and an auxiliary motor 233. The driven gear 231 is rotatably mounted in the mounting cavity 213 and is fixedly connected to the connecting ring 225. The driving gear 232 is rotatably disposed in the mounting cavity 213 and meshes with the driven gear 231. The auxiliary motor 233 is fixed in the mounting cavity 213, and its output shaft is fixedly connected to the driving gear 232. Furthermore, the connecting ring 225 is fitted onto one end of the driven gear 231 and fixedly connected by a screw (not shown in the figure), resulting in a simple structure and convenient assembly and disassembly. In addition, the driven gear 231 is provided with a blocking part 201, and a blocking member 234 is pivotally connected in the mounting cavity 213. The blocking end of the blocking member 234 is located on the movement trajectory of the blocking part 201. Furthermore, the auxiliary motor 233 is a stepper motor, which is not limited to this type.

[0046] The working principle of this embodiment is described in detail below:

[0047] When the main motor 24 of each fan head 20 is powered on, the main motor 24 drives the impeller 25 to rotate at high speed. Air enters the accommodating cavity 221 from the air inlet slot 222, is accelerated by the impeller to form wind, and the wind is output from the air outlet slot 223 to blow outward. When the drive mechanism 23 is powered on, the auxiliary motor 233 drives the drive gear 232 to rotate, and then the drive gear 232 drives the driven gear 231 to rotate, so that the cover 22 rotates 360° on the first inclined surface 211. The main motor 24 and the impeller 25 rotate 360° with the cover 22 to make the wind blowing range wider, and at the same time accelerate the indoor air circulation and better obtain fresh air.

[0048] When cleaning is required, first, separate the connection between the lower cover 12 and the main body 11. Then, each fan head 20 can be removed individually. After cleaning, position each fan head 20 on the lower cover 12, and then install and fix the lower cover 12 to the main body 11.

[0049] The key design feature of this invention is that by arranging multiple fan heads at intervals around the circumference of the bracket, and using a drive mechanism on each fan head to rotate the casing 360° on the first inclined surface, the orientation of the impeller is changed, allowing the airflow to cover every corner of the room, effectively expanding the airflow range, thereby achieving rapid circulation of indoor air. At the same time, each fan head can be disassembled and assembled as needed, bringing convenience to daily cleaning and maintenance.

[0050] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
