[0033] 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.

[0034] Referring to Figures 1 and 7 , this application discloses a fan light 100 comprising a housing 2, an air outlet structure 1, and a light source assembly. The housing 2 is positioned over and fixedly connected to the air outlet structure 1. An optical cavity is recessed in the bottom of the fan light 100, and the light source assembly is assembled within the cavity. The optical cavity can be located at the bottom of either the air outlet structure 1 or the housing 2, and can be adjusted based on actual needs without limitation.

[0035] Please refer to Figure 6. The outer 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 air flow from the air inlet 21 into the interior of the fan lamp 100 and is discharged through the air outlet 10.

[0036] 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.

[0037] 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 safe use.

[0038] 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, thereby driving external airflow into the air outlet structure 1 and 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.

[0039] Specifically, please refer to Figures 2 and 3. An assembly opening 114 is provided on the top of the shell 11. 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.

[0040] 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. An air cavity 1120 is provided in the extension portion 112. The air outlet 10 is provided on the extension portion 112. The air cavity 1120, the air outlet 10 and the assembly groove 110 are connected to each other, 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.

[0041] Preferably, the air outlet 10 is arranged around the periphery of the optical cavity so that the air outlet direction and the light outlet direction are the same. 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 this is not limited to this.

[0042] Preferably, a hollow region 13 is provided between two adjacent extensions 112. Multiple hollow regions 13 and multiple extensions 112 are assembled to form a complete circular ring, and the area of ​​a single hollow region 13 is 1 / 3 to 1 / 2 of the area of ​​a single extension 112. In other words, the extensions 112 are multiple independent components, which are arranged in a ring on the base 111 and can be integrally formed or detachably arranged, without limitation.

[0043] The housing 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 .

[0044] The plurality of air outlets 10 are arranged in a circular pattern around the central axis 113 of the housing 11, and the width of one end of the air outlet 10 is smaller than the width of the other end. This ensures that the wind speed at the end with the smaller width is greater than that at the end with the larger width, allowing the user to clearly feel the wind.

[0045] 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.

[0046] As shown in Figures 4 and 5 , 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 at the first arc segment 1021 is greater than the inner-outer diameter ratio at the second arc segment 1022. The inner-outer diameter ratio at 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 arranged, i.e., the inner-outer diameter ratio within an arc segment is the same, rather than a randomly changing curve.

[0047] Preferably, the inner-outer diameter ratio at the location of the second arc segment 1022 is 60%-80% of the inner-outer diameter ratio at the location of the first arc segment 1021. This configuration maximizes airflow efficiency. In this embodiment, the inner diameter a remains constant, while the outer diameter b varies with the different arc segments of the outer edge 102. Of course, in other embodiments, the outer diameter b may remain constant, and the inner diameter a, and thus the inner-outer diameter ratio, may be changed by adjusting the arc segments of the inner edge 101.

[0048] Preferably, the length of the first arc segment 1021 is 2 / 3 to 3 / 4 of the length of the outer edge 102. In this embodiment, the distance between the first arc segment 1021 and the central axis 113 is smaller than the distance between the second arc segment 1022 and the central axis 113. In other words, 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.

[0049] The outer extension 112 is arranged in an overall arc shape along the central axis 113 of the housing 11, positioning the air outlet 10 below the base 111. The outer 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. The upper arc surface 1121 has a first tangent, while the lower arc surface 1122 has a second tangent, with the first and second tangents being parallel to each other. This ensures uniformity in the overall size of the outer extension 112, ensuring uniform airflow.

[0050] 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 portion 112 of this structure has the best air outlet effect.

[0051] Preferably, the 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 toward the central axis 113 and is connected to the first arc segment 1021, while 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, thereby controlling the air outlet direction of the air outlet structure 1.

[0052] Preferably, the second connecting surface 11212 extends in a direction parallel to the central axis 113; alternatively, the second connecting surface 11212 extends in a direction away from the central axis 113. This allows the air outlet 10 corresponding to the first connecting surface 11211 to have a different air outlet direction than the air outlet 10 corresponding to the second connecting surface 11212, thereby expanding the air outlet range.

[0053] 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 on this.

[0054] To sum up, the air outlet structure 1 and the fan lamp 100 of the present application are connected to each other by setting 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. 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 maximum air output.

[0055] 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.
