[0009] A guide plate is annularly arranged on the outer periphery of the lower shell and forms the air outlet together with the lower shell. When the impeller rotates, it drives the external air flow to enter the air cavity from the air inlet, and is discharged from the air outlet after passing through the air outlet channel.

[0010] As a further improvement of the present invention, the flow blocking member is detachably connected to the lower shell, and the end of the flow blocking member away from the lower shell contacts the upper shell.

A clamping groove is provided at the bottom of the frame. One end of the guide plate is housed in the clamping groove, and the other end is squeezed and fixed between the flow blocking member and the upper shell.

[0012] As a further improvement of the present invention, a slope is provided on the side of the guide plate facing the lower shell to guide the direction of the air flow discharged from the air outlet.

[0013] As a further improvement of the present invention, the flow blocker is provided with a first flow blocking wall and a second flow blocking wall which are oppositely arranged. Both the first flow blocking wall and the second flow blocking wall are inclined in the same direction, and the inclination angles are different.

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 3 As shown, the present invention discloses a fan light 100, which includes a housing assembly 1, a fan assembly 2 and a suspension assembly 5. The housing assembly 1 includes an upper housing 14 and a lower housing 21. The upper housing 14 is provided with an air inlet 11. An air cavity is formed between the upper housing 14 and the lower housing 21. An air outlet 12 is formed on the outer periphery of the lower housing 21. The air inlet 11, the air cavity and the air outlet 12 are in communication with each other.

[0029] The fan assembly 2 is received inside the air cavity and cooperates with the upper housing 14 to form an air flow channel inside the housing assembly 1. The air flow channel is in communication with the air inlet 11 and the air outlet 12 to ensure the flow of air in the air cavity.

[0030] Specifically, the fan assembly 2 includes a motor assembly 22 and an impeller 23 fixed on 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 the external air flow to enter the air cavity from the air inlet 11 and flow along the air flow channel to the air outlet 12, and then be discharged from the air outlet 12. In this way, the circulation of the air flow is realized, and the arrow shown in the figure indicates the air flow direction.

[0031] Please refer to Figure 4 and Figure 5 As shown, the impeller 23 includes a positioning portion 231 fixedly connected to the motor assembly 22, an air outlet portion 232 for rotating and discharging air, and a connecting portion 233 connecting the positioning portion 231 and the air outlet portion 232. The lower housing 21 is provided with a first assembly groove 210. 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 housing 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 lamp 100 is made more firm. In this embodiment, through holes 2110 are formed in both the first assembly groove 210 and the reinforcing plate 24. The motor assembly 22 includes a motor housing 220 fixedly connected to the positioning portion 231 and a rotating shaft assembly 221 passing through the through holes 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.

[0033] The lower housing 21 further includes a second assembly groove 211 provided around the outside of the first assembly groove 210. The air outlet portion 232 is received 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, and the connecting portion 233 is connected to the positioning portion 231 and the air outlet portion 232 in an arc shape. By providing two assembly grooves on the lower housing 21, space for the impeller 23 to rotate is given. At the same time, it also enables the impeller 23 to blow air in all directions. In this embodiment, a plurality of vanes 2321 are provided on the air outlet portion 232 of the impeller 23, and the vanes 2321 are of a forward-curved structure extending towards the positioning portion 231. Through the forward-curved structure design, the air outlet efficiency is higher and more stable.

[0034] The fan lamp 100 further includes a plurality of flow restrictors 25 spaced apart and provided in a ring shape on one side of the lower housing 21 facing the impeller 23. An air outlet channel 250 is formed between two adjacent flow restrictors 25, and the air outlet channel 250 communicates with the air cavity and the air outlet 12. In other words, the flow restrictors 25 are provided in a ring shape at intervals around the outer periphery of the lower housing 21 and surround the impeller 23. The air flow driven by the impeller 23 flows out between the vanes 2321 and flows through the air outlet channel 250 to the air outlet 12. That is to say, by providing the flow restrictors 25, a plurality of air outlet channels 250 are artificially delimited, making the air outlet of the fan lamp 100 more uniform.

[0035] The flow restrictor 25 is detachably connected to the lower housing 21, and one end of the flow restrictor 25 away from the lower housing 21 contacts the upper housing 14. In this way, there is no gap between the flow restrictor 25 and the upper housing 14 to prevent the air flow from flowing into the air outlet 12 without passing through the air outlet channel 250.

[0036] The lower shell 21 is convexly provided with positioning posts 212, and the flow blocking member 25 is correspondingly provided with positioning holes 2511. The positioning posts 212 are received in the positioning holes 2511 to fix the flow blocking member 25 on the lower shell 21. For the convenience of installation, the positioning posts 212 can be prefabricated on the lower shell 21 in advance, and the installation area of the flow blocking member 25 can be set in advance. The positions of the positioning posts 212 are calculated and experimented to enable the air outlet channels 250 formed between two adjacent flow blocking members 25 to achieve the best air outlet efficiency.

[0037] Preferably, the positioning posts 212 are provided with grooves, and the positioning holes 2511 penetrate through the flow blocking member 25, so that after a positioning member passes through the positioning holes 2511 and cooperates with the grooves, the fixed connection between the flow blocking member 25 and the lower shell 21 can be realized. Of course, there are various fixing methods for the flow blocking member 25 and the lower shell 21, and it only needs to ensure that the flow blocking member 25 is fixed on the lower shell 21, and no restrictions are imposed on this.

[0038] The fan lamp 100 further includes a guide plate 4. The guide plate 4 is arranged around the outer periphery of the lower shell 21 and jointly forms the air outlet 12 with the lower shell 21. When the impeller 23 rotates, it drives the external air flow 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 side of the guide plate 4 facing the lower shell 21 is provided with an inclined surface to guide the direction of the air flow 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 lamp 100.

[0039] Please refer to Figure 6 As shown, the flow blocking member 25 can be approximately regarded as a hollow triangular shape. A second cavity 17 is formed inside the flow blocking member 25, and a first flow blocking wall 251 and a second flow blocking wall 252 are provided opposite to each other. Both the first flow blocking wall 251 and the second flow blocking wall 252 are inclined in the same direction, and the inclination angles are different. The air outlet channels 250 are formed between the first flow blocking wall 251 of each flow blocking member 25 and the second flow blocking wall 252 of the adjacent flow blocking member 25, and between the second flow blocking wall 252 of each flow blocking member 25 and the first flow blocking wall 251 of the adjacent flow blocking member 25. By setting the cross-sectional size of the air outlet channels 250, that is, the distance between the adjacent first flow blocking wall 251 and the second flow blocking wall 252, the overall air outlet efficiency of the fan lamp 100 can be adjusted.

[0040] The flow blocker 25 further includes a leading edge wall 253 and a trailing edge wall 254 connecting the first flow blocking wall 251 and the second flow blocking wall 252. The leading edge wall 253 is arc-shaped and located on the windward side, and the trailing edge wall 254 is located on the leeward side. The flow blocker 25 further includes an upper surface 255 and a lower surface 256 connecting the first flow blocking wall 251, the second flow blocking wall 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 flow blocker 25 is integrally arc-shaped. With such a setting, the flow blocker 25 is adapted to the lower housing 21, further increasing the fluidity of the line.

[0041] Define the plane where the diameter of the lower housing 21 is located as the reference plane. 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 flow blocking wall 251 and the second flow blocking 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 part of the upper surface 255 of the flow blocker 25 are exposed outside the lower housing 21 and are in contact with the inner housing 133, so that the airflow must flow through the air outlet channel 250 into the air outlet 12.

[0043] The flow blocker 25 is disposed around the outside of the impeller 23. The inclination directions of the first flow blocking wall 251 and the second flow blocking wall 252 are the same as the rotation direction of the impeller 23. If it is in the opposite direction, the flow blocker 25 cannot play the role of guiding the airflow.

[0044] Please refer to Figure 3 As shown, in this embodiment, the housing assembly 1 further includes a frame 13 disposed around the outside of the lower housing 21. A clamping groove 131 is provided at the bottom of the frame 13. One end of the flow guiding plate 4 is received in the clamping groove 131, and the other end is pressed and fixed between the flow blocker 25 and the upper housing 14 by the flow blocker 25. In this way, the fixed connection between the flow guiding plate 4 and the housing assembly 1 is realized, and the flow guiding plate 4 can be replaced according to requirements.

[0045] Of course, in other embodiments, the flow guiding plate 4 can be integrally formed with the housing assembly 1. In this way, the same guiding effect can be achieved while reducing the production cost. However, in this case, there is no possibility of replacing the flow guiding plate 4. When the air outlet directions with different requirements are encountered, the usage requirements of the user cannot be met.

[0046] In other embodiments, the deflector 4 can also be fixedly connected to the frame 13 by other fixing means, so that the deflector 4 can guide the airflow and change the air outlet direction of the fan lamp 100, and there is no limitation thereto.

[0047] Please refer to Figure 7 as shown. The fan lamp 100 further includes a lighting assembly 3 fixed below the lower housing 21. The lighting assembly 3 includes a direct-downlight source 30 and a face mask 31 covering the outside of the direct-downlight source 30. A mounting cavity (not shown) is recessed at the bottom of the lower housing 21, 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 the air outlet direction after the airflow passes through the deflector 4, so as to avoid affecting the air outlet efficiency of the fan lamp 100.

[0048] In summary, for the fan lamp 100 of the present invention, a plurality of spaced baffle members 25 are annularly arranged on the outer periphery of the lower housing 21, so that an air outlet channel 250 can be formed between two adjacent baffle members 25, and 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 providing a deflector 4 on the outer periphery of the lower housing 21, the air outlet 12 is formed between the deflector 4 and the lower housing 21, thereby changing the air outlet direction of the fan lamp 100.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
