[0028] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Referring to Figures 1 to 3, the present application discloses a fan lamp 100, including a shell assembly 1, a fan assembly 2 and a suspension assembly 5. The shell assembly 1 includes an upper shell 14 and a lower shell 21. The upper shell 14 is provided with an air inlet 11. A wind cavity is formed between the upper shell 14 and the lower shell 21. An air outlet 12 is formed on the periphery of the lower shell 21. The air inlet 11, the wind cavity and the air outlet 12 are connected to each other.

[0030] The fan assembly 2 is housed inside the air cavity and cooperates with the upper shell 14 to form an air flow channel inside the shell assembly 1. The air flow channel is interconnected with the air inlet 11 and the air outlet 12 to ensure that the air flows in the air cavity.

[0031] Specifically, the fan assembly 2 includes a motor assembly 22 and an impeller 23 fixed to the lower housing 21. The motor assembly 22 is fixedly connected to the impeller 23 to drive the impeller 23 to rotate. When the impeller 23 is driven by the motor assembly 22 to rotate, it drives external air from the air inlet 11 into the air cavity, flows along the air flow channel to the air outlet 12, and then is discharged from the air outlet 12. In this way, air circulation is achieved, and the arrows in the figure indicate the direction of air flow.

[0032] Please refer to Figures 4 and 5, the impeller 23 includes a positioning portion 231 fixedly connected to the motor assembly 22, an air outlet portion 232 that rotates to discharge air, and a connecting portion 233 connecting the positioning portion 231 and the air outlet portion 232. A first assembly groove 210 is provided on the lower shell 21, and the motor assembly 22 and the positioning portion 231 are both fixed in the first assembly groove 210 and can rotate relative to the first assembly groove 210.

[0033] The lower housing 21 also includes a reinforcing plate 24 secured within the first mounting groove 210. The positioning portion 231 is secured between the reinforcing plate 24 and the motor assembly 22. The reinforcing plate 24 provides a more robust structure for the fan light 100. In this embodiment, both the first mounting groove 210 and the reinforcing plate 24 are provided with a through-hole 2110. The motor assembly 22 includes a motor housing 220 fixedly connected to the positioning portion 231 and a rotating shaft assembly 221 extending through the through-hole 2110. One end of the rotating shaft assembly 221 is connected to the lower housing 21, and the other end is connected to the suspension assembly 5.

[0034] The lower shell 21 also includes a second assembly groove 211 arranged in an annular manner on the outside of the first assembly groove 210. The air outlet portion 232 is accommodated in the second assembly groove 211 and can rotate relative to the second assembly groove 211. The lower surface of the air outlet portion 232 is lower than the lower surface of the positioning portion 231. The connecting portion 233 is connected to the positioning portion 231 and the air outlet portion 232 in an arc shape. By opening two assembly grooves on the lower shell 21, space is provided for the impeller 23 to rotate, and at the same time, the impeller 23 can discharge air in all directions. In this embodiment, the air outlet portion 232 of the impeller 23 is provided with a plurality of vanes 2321, and the vanes 2321 are forward-bent structures extending toward the positioning portion 231. The forward-bent structural design makes the air outlet efficiency higher and more stable.

[0035] The fan light 100 also includes a plurality of baffles 25, each spaced apart on the side of the lower housing 21 facing the impeller 23. An air outlet channel 250 is formed between two adjacent baffles 25, connecting the air cavity and the air outlet 12. In other words, the baffles 25 are spaced apart around the periphery of the lower housing 21 and surround the impeller 23. Airflow driven by the impeller 23 flows out between the vanes 2321 and toward the air outlet 12 through the air outlet channels 250. In other words, the baffles 25 artificially create multiple air outlet channels 250, resulting in a more uniform airflow from the fan light 100.

[0036] The baffle 25 is detachably connected to the lower shell 21, and one end of the baffle 25 away from the lower shell 21 contacts the upper shell 14. This ensures that there is no gap between the baffle 25 and the upper shell 14, thereby preventing air from flowing into the air outlet 12 without passing through the air outlet channel 250.

[0037] The lower housing 21 is provided with a protruding positioning post 212, and the spoiler 25 is provided with a corresponding positioning hole 2511. The positioning post 212 is received in the positioning hole 2511 to secure the spoiler 25 to the lower housing 21. To facilitate installation, the positioning post 212 can be pre-set on the lower housing 21 to pre-determine the installation area for the spoiler 25. The position of the positioning post 212 is determined through calculation and experimentation to ensure that the air outlet channel 250 formed between two adjacent spoilers 25 achieves optimal air outlet efficiency.

[0038] Preferably, a groove is formed on the positioning post 212, and the positioning hole 2511 passes through the flow-blocking member 25, so that the positioning member, after passing through the positioning hole 2511, cooperates with the groove to achieve a fixed connection between the flow-blocking member 25 and the lower shell 21. Of course, there are many ways to fix the flow-blocking member 25 to the lower shell 21, and there is no limitation on this as long as the flow-blocking member 25 is fixed to the lower shell 21.

[0039] The fan light 100 also includes a deflector 4, which is disposed around the periphery of the lower housing 21 and, together with the lower housing 21, forms the air outlet 12. When the impeller 23 rotates, it drives external air from the air inlet 11 into the air cavity, passes through the air flow channel and the air outlet channel 250, and is discharged from the air outlet 12. Preferably, the deflector 4 has an inclined surface on the side facing the lower housing 21 to guide the direction of airflow discharged from the air outlet 12. The direction of the inclined surface of the deflector 4 can be pre-configured according to actual needs to control the airflow direction of the fan light 100.

[0040] As shown in FIG6 , the baffle 25 can be roughly viewed as a hollow triangle. A second cavity is formed within the baffle 25, and a first baffle wall 251 and a second baffle wall 252 are disposed opposite each other. The first baffle wall 251 and the second baffle wall 252 are inclined in the same direction at different angles. An air outlet channel 250 is formed between the first baffle wall 251 of each baffle 25 and the second baffle wall 252 of the adjacent baffle 25, and between the second baffle wall 252 of each baffle 25 and the first baffle wall 251 of the adjacent baffle 25. By adjusting the cross-sectional size of the air outlet channel 250, i.e., the distance between adjacent first baffle walls 251 and second baffle walls 252, the overall air outlet efficiency of the fan light 100 can be adjusted.

[0041] The spoiler 25 also includes a leading edge wall 253 and a trailing edge wall 254 connecting the first spoiler 251 and the second spoiler 252. The leading edge wall 253 is arranged in an arc shape and is located on the windward side, while the trailing edge wall 254 is located on the leeward side. The spoiler 25 also includes an upper surface 255 and a lower surface 256 connecting the first spoiler 251, the second spoiler 252, the leading edge wall 253, and the trailing edge wall 254. The upper surface 255 is a convex surface that protrudes from the trailing edge wall 254 toward the leading edge wall 253, while the lower surface 256 is a concave surface that is recessed from the trailing edge wall 254 toward the leading edge wall 253, thereby giving the spoiler 25 an overall arc shape. This configuration allows the spoiler 25 to adapt to the lower shell 21, further enhancing the fluidity of the lines.

[0042] The plane of the diameter of the lower shell 21 is defined as a reference plane, and the projected area of ​​the upper surface 255 on the reference plane is smaller than the projected area of ​​the lower surface 256 on the reference plane, so that the first baffle 251 and the second baffle 252 are both inclined in a direction perpendicular to the reference plane. This further enhances the guiding effect on the airflow.

[0043] In this embodiment, the trailing edge wall 254 and a portion of the upper surface 255 of the spoiler 25 are exposed outside the lower shell 21 and abut against the inner shell 133 so that the airflow must pass through the air outlet channel 250 to flow into the air outlet 12.

[0044] The baffle 25 is disposed around the outer side of the impeller 23. The inclination direction of the first baffle wall 251 and the second baffle wall 252 is the same as the rotation direction of the impeller 23. If the inclination direction is opposite, the baffle 25 cannot play the role of guiding the airflow.

[0045] Referring to FIG3 , in this embodiment, the housing assembly 1 further includes a frame 13 disposed around the outside of the lower housing 21. A snap-fit ​​groove 131 is provided at the bottom of the frame 13. One end of the deflector 4 is received in the snap-fit ​​groove 131, while the other end is squeezed and fixed by the baffle 25 between the baffle 25 and the upper housing 14. This ensures a secure connection between the deflector 4 and the housing assembly 1, and allows replacement of the deflector 4 as needed.

[0046] Of course, in other embodiments, the guide plate 4 can be integrally formed with the shell assembly 1. In this way, the same guiding effect can be achieved while reducing production costs. However, in this way, the possibility of replacing the guide plate 4 is lost, and when different air outlet directions are required, the user's needs cannot be met.

[0047] In other embodiments, the guide plate 4 may also be fixedly connected to the frame 13 by other fixing methods, so that the guide plate 4 can guide the airflow and change the air outlet direction of the fan light 100. There is no limitation on this.

[0048] Please refer to Figure 7. The fan light 100 also includes a lighting assembly 3 fixed below the lower shell 21. The lighting assembly 3 includes a direct-down light source 30 and a mask 31 that covers the exterior of the direct-down light source 30. The bottom of the lower shell 21 is recessed with a mounting cavity (not shown), and the lighting assembly 3 is fixed within the mounting cavity. It should be noted that the lighting assembly 3 cannot block the air outlet 12 or the direction of the airflow after passing through the deflector 4, so as not to affect the air output efficiency of the fan light 100.

[0049] To sum up, the fan lamp 100 of the present application can form an air outlet channel 250 between two adjacent air outlet channels 25 by arranging a plurality of spaced-apart baffles 25 around the outer periphery of the lower shell 21, so that the airflow driven by the rotation of the impeller 23 flows from the air outlet channel 250 to the air outlet 12, making the air outlet intensity of the fan lamp 100 higher; at the same time, by arranging a guide plate 4 on the outer periphery of the lower shell 21, the air outlet 12 is formed between the guide plate 4 and the lower shell 21, thereby changing the air outlet direction of the fan lamp 100.

[0050] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
