[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figures 1 to 3 As shown, the utility model 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, and the air inlet 11, the wind cavity and the air outlet 12 are interconnected.

[0029] The fan assembly 2 is accommodated 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 air flow in the air cavity.

[0030] Specifically, the fan assembly 2 includes a motor assembly 22 and an impeller 23 fixed on the lower shell 21, and the motor assembly 22 is fixedly connected to the impeller 23 to drive the impeller 23 to rotate. When the impeller 23 is driven to rotate by the motor assembly 22, the external airflow is driven to enter the air cavity from the air inlet 11, and flows along the air flow channel to the air outlet 12, and then discharged from the air outlet 12. In this way, the circulation of the airflow is realized, and the arrows in the figure show the direction of the airflow.

[0031] Please combine Figure 4 and Figure 5As shown, 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.

[0032] The lower shell 21 further includes a reinforcing plate 24 fixed in the first assembly groove 210, and the positioning portion 231 is fixed between the reinforcing plate 24 and the motor assembly 22. By providing the reinforcing plate 24, the structure of the fan light 100 is made more solid. In this embodiment, a through hole 2110 is provided on both the first assembly groove 210 and the reinforcing plate 24, and the motor assembly 22 includes a motor housing 220 fixedly connected to the positioning portion 231 and a shaft assembly 221 passing through the through hole 2110, one end of the shaft assembly 221 is connected to the lower shell 21, and the other end is connected to the suspension assembly 5.

[0033] The lower shell 21 also includes a second assembly groove 211 arranged around the outside of the first assembly groove 210, the air outlet 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 232 is lower than the lower surface of the positioning portion 231, and the connecting portion 233 is connected to the positioning portion 231 and the air outlet 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 also discharge air in all directions. In this embodiment, the air outlet 232 of the impeller 23 is provided with a plurality of fins 2321, and the fins 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.

[0034] The fan light 100 further includes a baffle 25, wherein the baffle 25 is provided in a plurality and arranged in a spaced ring on the side of the lower shell 21 facing the impeller 23, and an air outlet channel 250 is formed between two adjacent baffles 25, and the air outlet channel 250 connects the wind cavity and the air outlet 12. In other words, the baffle 25 is arranged in a spaced ring on the outer periphery of the lower shell 21 and surrounds the impeller 23, and the airflow driven by the impeller 23 flows out from between the fins 2321 and flows to the air outlet 12 through the air outlet channel 250. In other words, by providing the baffle 25, a plurality of air outlet channels 250 are artificially demarcated, so that the air outlet of the fan light 100 is more uniform.

[0035] 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. In this way, there is no gap between the baffle 25 and the upper shell 14, so as to prevent the airflow from flowing into the air outlet 12 without passing through the air outlet channel 250.

[0036] The lower shell 21 is provided with a locating column 212, and the baffle 25 is provided with a locating hole 2511 correspondingly. The locating column 212 is received in the locating hole 2511 to fix the baffle 25 on the lower shell 21. For easy installation, the locating column 212 can be pre-positioned on the lower shell 21 in advance, and the installation area of ​​the baffle 25 can be set in advance. The position of the locating column 212 is calculated and tested so that the air outlet channel 250 formed between two adjacent baffles 25 can achieve the best air outlet efficiency.

[0037] Preferably, a groove is formed on the positioning column 212, and the positioning hole 2511 passes through the flow-blocking member 25, so that the positioning member passes through the positioning hole 2511 and 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 and the lower shell 21, and it is only necessary to ensure that the flow-blocking member 25 is fixed to the lower shell 21, and there is no limitation on this.

[0038] The fan light 100 further includes a guide plate 4, which is arranged around the outer periphery of the lower shell 21 and forms the air outlet 12 together with the lower shell 21. When the impeller 23 rotates, it drives the external airflow to enter the air cavity from the air inlet 11, and then is discharged from the air outlet 12 after passing through the air flow channel and the air outlet channel 250. Preferably, the guide plate 4 is provided with an inclined surface on the side facing the lower shell 21 to guide the direction of the airflow discharged from the air outlet 12. The inclined surface direction of the guide plate 4 can be prefabricated according to actual needs to control the air outlet direction of the fan light 100.

[0039] Please combine Figure 6 As shown, the baffle 25 can be approximately regarded as a hollow triangle, a second cavity 17 is formed inside the baffle 25, and a first baffle wall 251 and a second baffle wall 252 are arranged opposite to each other, the first baffle wall 251 and the second baffle wall 252 are inclined in the same direction, and the inclination angles are different. The 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 setting the cross-sectional size of the air outlet channel 250, that is, the distance between the adjacent first baffle walls 251 and the second baffle wall 252, the overall air outlet efficiency of the fan light 100 can be adjusted.

[0040] 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, and 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 protruding from the trailing edge wall 254 toward the leading edge wall 253, and the lower surface 256 is a concave surface recessed from the trailing edge wall 254 toward the leading edge wall 253, so that the spoiler 25 is in an arc shape as a whole. In this way, the spoiler 25 is adapted to the lower shell 21, further increasing the fluidity of the lines.

[0041] The plane where the diameter of the lower shell 21 lies is defined as a reference plane, and the projection area of ​​the upper surface 255 on the reference plane is smaller than the projection area of ​​the lower surface 256 on the reference plane, so that the first baffle wall 251 and the second baffle wall 252 are both inclined in a direction perpendicular to the reference plane. In this way, the guiding effect on the airflow is further increased.

[0042] 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 .

[0043] The baffle 25 is disposed around the outer side of the impeller 23, and 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 it is the opposite direction, the baffle 25 cannot play the role of guiding the airflow.

[0044] Please combine Figure 3 As shown, in this embodiment, the housing assembly 1 further includes a frame 13 arranged around the outer side of the lower housing 21, and a clamping groove 131 is provided at the bottom of the frame 13. One end of the guide plate 4 is received in the clamping groove 131, and the other end is squeezed and fixed by the baffle 25 between the baffle 25 and the upper housing 14. In this way, the guide plate 4 is fixedly connected to the housing assembly 1, and the guide plate 4 can be replaced as needed.

[0045] 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 case, there is no possibility of replacing the guide plate 4, and when different air outlet directions are required, the user's needs cannot be met.

[0046] 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, and there is no limitation to this.

[0047] Please combine Figure 7 As shown. The fan light 100 also includes a lighting assembly 3 fixed below the lower shell 21, and the lighting assembly 3 includes a direct-down light source 30 and a mask 31 covering the outside 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 in the mounting cavity. It should be noted that the lighting assembly 3 cannot block the air outlet 12, or block the air outlet direction after the airflow passes through the guide plate 4, so as to avoid affecting the air outlet efficiency of the fan light 100.

[0048] In summary, the fan light 100 of the present invention is provided with a plurality of spaced-apart baffles 25 around the outer periphery of the lower shell 21, so that an air outlet channel 250 can be formed between two adjacent baffles 25, so that the airflow driven by the rotation of the impeller 23 flows from the air outlet channel 250 to the air outlet 12, so that the air outlet intensity of the fan light 100 is higher; at the same time, a guide plate 4 is provided on the outer periphery of the lower shell 21, so that 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 light 100.

[0049] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
