For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figures 1 to 4 This utility model discloses a duct fan, which includes a fan body 100, a drive assembly 200, and a light panel module 300. The fan body 100 has an air cavity 111 and an air outlet 112 and an air inlet 121A, both of which are connected to the air cavity 111 and are arranged vertically. The air inlet 121A is located at the bottom of the fan body 100 and is arranged downwards. The drive assembly 200 is disposed on the fan body 100. The light panel module 300 is vertically and vertically disposed on the fan body 100 and can emit light downwards. The light panel module 300 is connected to the drive assembly 200. The drive assembly 200 can drive the light panel module 300 to move upwards to the air inlet 121A to close the air inlet 121A, and can also drive the light panel module 300 to move downwards below the air inlet 121A to open the air inlet 121A. The light panel module 300 can be configured as an LED light panel.

[0019] Through the aforementioned structure, on the one hand, the liftable lamp panel module 300, when in the closed position, covers the air inlet 121A, forming a physical barrier that greatly reduces or prevents dust and other small foreign objects from entering the air cavity 111. This not only significantly improves the dustproof capability of the duct fan but also effectively reduces the impact of dust accumulation on the operating efficiency and lifespan of internal components, while also reducing the frequency and cost of internal cleaning and maintenance. On the other hand, integrating the lighting and air inlet 121A baffle functions into a single lamp panel module 300, with its lifting movement controlled by a drive component 200, eliminates the additional installation space and structural components required for independent lighting units in traditional designs. This makes the overall structure of the duct fan simpler and more compact, reducing the size of the equipment and the space it occupies.

[0020] The fan body 100 includes a fan shell 110 and a fan cover 120.

[0021] Reference Figures 1 to 4 The fan housing 110 is provided with the aforementioned air cavity 111 and the aforementioned air outlet 112. The air cavity 111 is provided with a downwardly facing opening 111A. The fan cover 120 is detachably provided at the bottom of the fan housing 110 to close the opening 111A. The fan cover 120 is provided with the aforementioned air inlet 121A. The drive assembly 200 and the lamp panel module 300 are both provided on the fan cover 120.

[0022] It is understood that, in this embodiment, reference is made to... Figure 3 and Figure 4 The fan cover 120 includes only the cover body 121, which is detachably disposed at the bottom of the fan housing 110 to close the opening 111A. The cover body 121 is provided with the aforementioned air inlet 121A. The drive assembly 200 and the lamp panel module 300 are both disposed on the cover body 121.

[0023] It is understood that the detachable connection between the cover body 121 and the fan housing 110 is achieved through an elastic element and a hole assembly structure, as shown in the applicant's previous application ZLCN222415395U, and therefore will not be repeated here. Of course, in some embodiments, the detachable connection between the cover body 121 and the fan housing 110 can be achieved by using screws.

[0024] With the above structure, when it is necessary to clean the air cavity 111, maintain the drive assembly 200, or replace the lamp panel module 300, all core components can be directly accessed by simply disassembling the fan cover 120 (i.e., the cover body 121), without the need for complex disassembly of the entire duct fan, which greatly reduces the difficulty, time and cost of daily maintenance and troubleshooting.

[0025] Both the drive assembly 200 and the lamp panel module 300 are located on the cover body 121. For details, please refer to... Figure 3 and Figure 4 The cover body 121 is provided with a mounting bracket 121B located above the air inlet 121A, and the drive assembly 200 and the lamp panel module 300 are respectively located on the upper and lower sides of the mounting bracket 121B.

[0026] The driver component 200 and the lamp board module 300 are connected. For details, please refer to [link / reference]. Figure 3 and Figure 4 The mounting bracket 121B is provided with a connecting cylinder 121B1, and the lamp panel module 300 is provided with a connecting block 310. The connecting block 310 is vertically and flexibly inserted through the connecting cylinder 121B1. The connecting block 310 is provided with a toothed portion 311. The drive assembly 200 includes a motor component 210 and a gear component 220 disposed on the output shaft of the motor component 210. The motor component 210 is disposed on the mounting bracket 121B, and the gear component 220 meshes with the toothed portion 311. The motor component 210 can drive the gear component 220 to rotate, so that the lamp panel module 300 can be raised and lowered through the gear component 220 and the toothed portion 311.

[0027] To improve the stability of the light panel module 300 during the lifting process, refer to Figure 3 and Figure 4 The mounting bracket 121B is equipped with a guide cylinder 121B2, and the lamp panel module 300 is equipped with a guide post 320. A limiting block 321A is provided on the outer wall of the guide post 320. The guide post 320 is vertically and flexibly inserted into the guide cylinder 121B2, and the limiting block 321A can abut against the mounting bracket 121B to restrict the downward movement of the lamp panel module 300. The limiting block 321A prevents the lamp panel module 300 from moving excessively downward.

[0028] The outer wall of the guide post 320 is provided with a limiting block 321A. For details, please refer to... Figure 3 The side wall of the guide post 320 is provided with a spring piece 321 that can be pressed and rebounded. The spring piece 321 is provided with a limiting block 321A. Pressing the spring piece 321 can drive the limiting block 321A to release from contact with the mounting bracket 121B, so that the guide post 320 can move down and disengage from the guide cylinder 121B2.

[0029] Understandably, the pressing spring portion 321 can cause the limiting block 321A to release from contact with the mounting bracket 121B, so that the guide post 320 can move downward and disengage from the guide cylinder 121B2. Similarly, the pressing spring portion 321 can cause the limiting block 321A to not interfere with the guide post 320's insertion into the guide cylinder 121B2, so as to facilitate the installation of the lamp panel module 300.

[0030] In some embodiments, refer to Figures 5 to 8 The fan cover 120 includes a cover body 121 and a rotating ring 122. The rotating ring 122 is rotatably disposed on the upper side of the cover body 121. The rotating ring 122 is detachably disposed on the bottom of the fan shell 110 to close the opening 111A of the cover body 121. The cover body 121 is provided with the aforementioned air inlet 121A and a mounting bracket 121B located above the air inlet 121A. The drive assembly 200 and the lamp panel module 300 are respectively disposed on the upper and lower sides of the mounting bracket 121B.

[0031] It is understood that the detachable connection between the rotating ring 122 and the fan housing 110 is achieved through an elastic element and a hole assembly structure, as shown in the applicant's previous application ZLCN222415395U, and therefore will not be repeated here. Of course, in some embodiments, the detachable connection between the rotating ring 122 and the fan housing 110 can be achieved by screwing; the way the drive assembly 200 and the lamp board module 300 are disposed on the mounting bracket 121B is the same as in the above embodiments, and therefore will not be repeated here either.

[0032] With the above structure, the cover body 121 is polygonal, and the rotating ring 122 is designed to allow the cover body 121 to rotate relative to the fan shell 110 so that it can be rotated and aligned to be inserted into the reserved hole in the ceiling when the duct fan is installed in the ceiling (the shape of the reserved hole matches the shape of the cover body 121).

[0033] 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.
