[0032] 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.

[0033] See also Figure 1 and Figure 7 As shown, the utility model discloses a fan light 100, including a housing 2, an air outlet structure 1 and a light source assembly, wherein the housing 2 is disposed on the outside of the air outlet structure 1 and is fixedly connected to the air outlet structure 1, and an optical cavity is recessed at the bottom of the fan light 100, and the light source assembly is assembled in the optical cavity. The optical cavity can be disposed at the bottom of one of the air outlet structure 1 and the housing 2, and can be adjusted according to actual conditions, and there is no limitation on this.

[0034] Please combine Figure 6 As shown, the shell 2 is provided with an air inlet 21, and the air outlet structure 1 is provided with an air outlet 10. The air inlet 21 and the air outlet 10 are connected to each other. When the air outlet structure 1 is in operation, it drives the external airflow into the fan lamp 100 from the air inlet 21 and is discharged through the air outlet 10.

[0035] Of course, the air outlet structure 1 is not limited to being installed in the fan lamp 100, and can also be applied to other fans without limitation.

[0036] The air outlet structure 1 includes a shell 11 and a fan assembly 12. The shell 11 is recessed with an assembly groove 110. The fan assembly 12 is assembled in the assembly groove 110 and is hidden by the shell 11 to ensure safety in use.

[0037] The fan assembly 12 includes an impeller assembly 121 and a motor assembly 122. The motor assembly 122 drives the impeller assembly 121 to rotate, so as to drive the external airflow to flow into the air outlet structure 1 and be discharged from the air outlet 10. In the direction facing the assembly slot 110, the impeller assembly 121 is accommodated in the assembly slot 110 and is shielded by the housing 11, and the motor assembly 122 can be observed.

[0038] For details, please combine Figure 2 and Figure 3As shown, an assembly opening 114 is provided on the top of the shell 11, and the assembly groove 110 includes a first assembly groove 1101 blocked by the shell 11 and a second assembly groove 1102 exposed to the assembly opening 114, the first assembly groove 1101, the second assembly groove 1102 and the air outlet 10 are connected to each other, the impeller assembly 121 is assembled in the first assembly groove 1101, and the motor assembly 122 is assembled in the second assembly groove 1102.

[0039] The shell 11 includes a base 111 and an extension portion 112 extending outward from the base 111, the extension portion 112 is provided with multiple portions and is arranged in a ring around the outer periphery of the base 111, the assembly groove 110 is recessed in the base 111, and an air cavity 1120 is provided in the extension portion 112. The air outlet 10 is arranged on the extension portion 112, and the air cavity 1120, the air outlet 10 and the assembly groove 110 are interconnected, so that when the impeller assembly 121 is in operation, it can drive external airflow to enter from the assembly groove 110, and flow out from the circumference of the impeller assembly 121, and be discharged from the air outlet 10 after passing through the air cavity 1120.

[0040] Preferably, the air outlet 10 is arranged around the periphery of the optical cavity so that the air outlet direction is the same as the light outlet direction. In this embodiment, the light source assembly emits light downward, and the air outlet 10 opens downward along the central axis 113 of the housing 11, so that the air outlet structure 1 emits air downward. Of course, in other embodiments, the air outlet direction and the light outlet direction of the light source assembly can be adjusted according to actual conditions, and there is no limitation on this.

[0041] Preferably, a hollow area 13 is provided between two adjacent extensions 112, and a plurality of hollow areas 13 and a plurality of extensions 112 are assembled into a complete ring, and the area of ​​a single hollow area 13 is 1 / 3 to 1 / 2 of the area of ​​a single extension 112. In other words, the extensions 112 are a plurality of independent components, which are arranged on the base 111 in a ring, and can be integrally formed or detachably arranged, without limitation.

[0042] The shell 11 is further provided with a guide portion 131 corresponding to the hollow area 13 . The guide portion 131 separates two adjacent air cavities 1120 and guides the airflow flowing out of the fan assembly 12 in a circumferential direction into the air cavities 1120 .

[0043] In the direction of the central axis 113 of the housing 11, the plurality of air outlets 10 are arranged in a circular ring around the central axis 113, and in the arrangement direction of the air outlets 10, the width of one end of the air outlet 10 is smaller than the width of the other end. In this way, the wind speed at the end with the smaller width is greater than the wind speed at the end with the larger width, so that the user can clearly feel the wind.

[0044] Specifically, the air outlet 10 includes an inner edge 101 and an outer edge 102 that are concentrically arranged. The distance from the central axis 113 to the inner edge 101 is defined as the inner diameter a of the air outlet 10, and the distance from the central axis 113 to the outer edge 102 is defined as the outer diameter b of the air outlet 10. The ratio of the inner diameter a to the outer diameter b is the inner-outer diameter ratio of the air outlet 10. The inner-outer diameter ratio of one end of the air outlet 10 is greater than that of the other end.

[0045] Please combine Figure 4 and Figure 5 As shown, the outer edge 102 includes a first arc segment 1021, a second arc segment 1022, and a transition segment 1023 connecting the first arc segment 1021 and the second arc segment 1022. The inner-outer diameter ratio corresponding to the position of the first arc segment 1021 is greater than the inner-outer diameter ratio corresponding to the position of the second arc segment 1022, and the inner-outer diameter ratio corresponding to the position of the transition segment 1023 gradually decreases from the first arc segment 1021 toward the second arc segment 1022. In other words, the width of the air outlet 10 is still regularly set as a whole, that is, the inner-outer diameter ratio within an arc segment is the same, rather than a randomly changing curve.

[0046] Preferably, the inner-outer diameter ratio corresponding to the position of the second arc segment 1022 accounts for 60%-80% of the inner-outer diameter ratio corresponding to the position of the first arc segment 1021. Such a setting can ensure the air outlet efficiency to the greatest extent. In this embodiment, the size of the inner diameter a remains unchanged, and the size of the outer diameter b changes with the different arc segments of the outer edge 102; of course, in other embodiments, the size of the outer diameter b may remain unchanged, and the size of the inner diameter a is changed by adjusting the arc segment of the inner edge 101, thereby changing the inner-outer diameter ratio.

[0047] Preferably, the length of the first arc segment 1021 accounts for 2 / 3 to 3 / 4 of the length of the outer edge 102. In this embodiment, the distance from the first arc segment 1021 to the central axis 113 is smaller than the distance from the second arc segment 1022 to the central axis 113, that is, the width of the air outlet 10 corresponding to the first arc segment 1021 is narrower, and the length it occupies is also longer than that of the second arc segment 1022.

[0048] In the direction of the central axis 113 of the shell 11, the extension 112 is arranged in an arc shape as a whole, so that the air outlet 10 is located below the base 111. The extension 112 includes an upper arc surface 1121 connecting the base 111 and the outer edge 102, and a lower arc surface 1122 connecting the base 111 and the inner edge 101. It is defined that the upper arc surface 1121 has a first tangent line, and the lower arc surface 1122 has a second tangent line, and the first tangent line and the second tangent line are parallel to each other. In this way, the overall size of the extension 112 is uniform, ensuring the uniformity of air outlet.

[0049] Preferably, the angles between the first tangent line and the second tangent line and the central axis 113 are both between 20° and 40°. Experiments have shown that the extension 112 under this structure has the best air outlet effect.

[0050] Preferably, one end of the upper arc surface 1121 connected to the outer edge 102 has a first connecting surface 11211 and a second connecting surface 11212, the first connecting surface 11211 extends in a direction close to the central axis 113 and is connected to the first arc segment 1021, and the second connecting surface 11212 is connected to the second arc segment 1022. In other words, by controlling the orientation of the first connecting surface 11211 and the second connecting surface 11212 in a direction perpendicular to the central axis 113, the opening direction of the air outlet 10 is controlled, and thus, the air outlet direction of the air outlet structure 1 is controlled.

[0051] Preferably, the extension direction of the second connection surface 11212 is parallel to the direction of the central axis 113; or, the second connection surface 11212 extends in a direction away from the central axis 113. In this way, the air outlet direction of the air outlet 10 corresponding to the first connection surface 11211 is different from the air outlet direction of the air outlet 10 corresponding to the second connection surface 11212, thereby expanding the air outlet range.

[0052] When the second connecting surface 11212 extends in a direction away from the central axis 113, the air outlet direction of the air outlet structure 1 can be further expanded. Of course, the actual angle can be adjusted according to actual conditions and there is no limitation to this.

[0053] In summary, the air outlet structure 1 and the fan lamp 100 of the utility model are provided with an extension portion 112 on the periphery of the base 111 of the shell 11, so that the assembly groove 110 of the base 111, the wind cavity 1120 of the extension portion 112 and the air outlet 10 are interconnected, and by setting the two ends of the air outlet 10 to different widths, the air outlet structure 1 can control the air outlet direction while ensuring the central wind speed and the maximum air output.

[0054] 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.
