Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and in particular to a ceiling rotating fan with lights. Background Technology

[0002] Ceiling-mounted oscillating fans, as embedded ventilation devices, have been increasingly used in commercial and public buildings in recent years. They employ an integrated design of axial-flow fans and ceiling panels, achieving concealed installation through pre-drilled holes in the modular ceiling panels. Installation only requires replacing the existing ceiling module and fixing it to the frame with screws, offering advantages such as space saving and maintaining the overall architectural aesthetic. However, this technology has significant drawbacks in practical applications: First, the air inlet is located in the enclosed space above the ceiling, where the internal structure of the ceiling restricts airflow circulation, resulting in low fresh air supply efficiency, reduced air volume, and disordered airflow. Second, the embedded structure leads to a lack of heat dissipation channels for the motor and fan body, causing heat accumulation during continuous operation and potentially exceeding motor temperature limits, directly affecting the stability and lifespan of the equipment. Third, in existing improvements attempting to integrate LED lighting functions, the combined heat from the lighting module and driver circuit further exacerbates localized temperature rise, and traditional heat dissipation designs cannot meet the thermal management requirements of this combined function, leading to accelerated light decay, electronic component failure, and other cascading malfunctions. Therefore, further improvements are needed. Utility Model Content

[0026] Example

[0027] Reference Figures 1 to 3 The present invention proposes a ceiling oscillating fan with lights, comprising: an upper cover 10, a lower cover 20, an air guide plate 30, an impeller 40, a main motor 50, and a lighting assembly 60;

[0028] The upper cover 10 has an upward convex structure and can be installed on the ceiling frame; the lower cover 20 has a downward convex structure and can be detachably installed on the upper cover 10 to form a receiving cavity; the impeller 40 and the main motor 50 are installed in the receiving cavity; an air guide plate 30 is provided in the lower middle part of the lower cover 20; several transversely penetrating side air inlets 21 are opened on the outer periphery of the lower cover 20; the lighting assembly 60 is located between the air guide plate 30 and the side air inlets 21.

[0029] In this invention, the illuminated ceiling oscillating fan achieves functional integration and performance optimization of ventilation and lighting through innovative structural design. The side air inlet slot 21 and the air guide plate 30 work together to overcome the limitations of traditional top air inlets. The side air inlet slot 21 forms a multi-directional air intake channel, and combined with the centrifugal guiding characteristics of the air guide plate 30, significantly enhances air circulation efficiency and effectively increases the amount of fresh air supplied. An active cooling system is established; the axial airflow generated by the main motor 50 during operation forms a ring-shaped cooling air curtain through the air guide plate 30, simultaneously washing the heat dissipation surface of the lighting component 60 and the motor housing surface, achieving dynamic forced convection cooling of heat from both systems and effectively improving heat dissipation performance.

[0030] In this embodiment, the air guide plate 30 has a disc-shaped structure; the lower cover 20 is provided with an annular light groove 22, which is arranged around the outside of the air guide plate 30; the lighting assembly 60 is detachably embedded in the annular light groove 22. The radial limiting design of the annular light groove 22 ensures that the LED module and the air guide plate 30 maintain a precise distance, which avoids turbulence disturbance and achieves wide-angle diffuse reflection lighting.

[0031] Specifically, the lower cover 20 is equipped with an annular lamp cover 70, which is detachably embedded below the annular lamp slot 22. The snap-fit ​​design of the annular lamp cover 70 forms a sealed dustproof interface, effectively preventing dust from entering the motor compartment through the lamp slot. Its semi-transparent PP material combines light transmission and temperature resistance, achieving a soft surface light source effect while forming a physical isolation layer for heat dissipation airflow.

[0032] Furthermore, the annular light groove 22 has several latching slots 23, and the annular light cover 70 has several latching hooks 71, which can be latched into the latching slots 23. The elastic interlocking mechanism between the latching slots 23 and the latching hooks 71 enables tool-free disassembly and assembly of the light cover through multiple evenly distributed locking points, making disassembly and assembly convenient.

[0033] In this embodiment, multiple side air intake slots 21 are provided and arranged circumferentially outside the annular light trough 22. The layout strategy of placing the side air intake slots 21 outside the annular light trough 22 forms a three-level functional zone of "air intake-lighting-air diversion".

[0034] In this embodiment, a central mounting base 24 is provided in the middle of the lower cover 20, and the central mounting base 24 is connected to the outer periphery of the lower cover 20 through a connecting beam 25; the main motor 50 is mounted above the central mounting base 24, and the air guide plate 30 is mounted below the central mounting base 24. The central mounting base 24 and the connecting beam 25 form a "spoke-type" load-bearing frame, and this topology simultaneously forms an annular airflow guiding cavity, so that the motor cooling airflow is accelerated and discharged along the gap of the connecting beam 25.

[0035] Furthermore, a synchronous motor 80 is provided on the lower side of the central mounting base 24. The synchronous motor 80 is used to rotate the air guide plate 30. The rotation mechanism of the air guide plate 30 driven by the synchronous motor 80 achieves periodic deflection of the air delivery angle by dynamically changing the angle of attack of the guide vanes.

[0036] In this embodiment, an air guide connector 81 is provided on the lower side of the central mounting base 24; the air guide connector 81 is mounted on the output shaft of the synchronous motor 80; and the air guide plate 30 is detachably mounted on the lower side of the air guide connector 81.

[0037] In this embodiment, the impeller 40 is provided with at least three blades. For example, three, four, five, six or more blades may be arranged.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
