[0058] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0059] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and are not intended to limit the present disclosure.

[0060] In view of the above technical problems, the present disclosure provides a fan light, such as Figure 1-Figure 4 As shown, the fan lamp includes a housing 1, an impeller 2, a guide vane 3 and a lamp body 4. The impeller 2 is located inside the housing 1, and includes a wheel disc 21 and blades 22. The blades 22 are fixed to the wheel disc 21, and an impeller area air duct 101 is formed between the first part 1a of the housing 1 and the wheel disc 21. The lamp body 4 is located below the wheel disc 21, and a guide vane area air duct 102 is formed between the lamp body 4 and the second part 1b of the housing 1. The two ends of the guide vane 3 are connected to the lamp body 4 and the second part 1b respectively. Figure 5-Figure 7 As shown, in the reference plane, assuming that the angle between the inner wall of the first part 1a and the inner wall of the second part 1b is α, then 170°≤α≤180°, wherein the reference plane coincides with the axis of the impeller 2.

[0061] In which, the shell 1 can be an integral structure, and the angle α between the inner wall of the first part 1a and the inner wall of the second part 1b is the angle between the tangent of the end of the inner wall of the first part 1a and the tangent of the top of the inner wall of the second part 1b. The end of the first part 1a and the top of the second part 1b are the connection points of the first part 1a and the second part 1b.

[0062] There is a gap between the wheel disc 21 and the lamp body 4 , or the bottom surface of the wheel disc 21 is rotatably connected to the top surface of the lamp body 4 .

[0063] An air inlet is formed between the top end of the first part 1 a of the housing 1 and the top end of the wheel disc 21 , and an air outlet is formed between the bottom end of the second part 1 b of the housing 1 and the bottom end of the lamp body 4 .

[0064] The impeller 2 further includes a motor 23 , which is fixed inside the wheel disc 21 , and is used to drive the wheel disc 21 to rotate.

[0065] The technical solution provided by the embodiment of the present disclosure is that, in the reference plane, the angle α between the inner wall of the first part 1a of the shell 1 and the inner wall of the second part 1b is 170°-180°. In this way, the inclination of the inner wall of the first part 1a and the inner wall of the second part 1b is basically the same, so that the airflow can flow smoothly from the impeller area air duct 101 to the end of the guide vane area air duct 102, so that the loss of airflow is small, thereby increasing the air supply range of the air outlet. At the same time, setting the shell 1 to the above shape can also make it difficult for dust to accumulate on the inner wall of the shell 1, so that the airflow at the air outlet is cleaner.

[0066] In addition, the guide vane 3 can increase the wind pressure at the air outlet, thereby increasing the air supply distance of the air outlet.

[0067] In some examples, such as Figure 5-Figure 7 As shown, in the reference plane, the line connecting the top and bottom of the outer wall of the housing 1 is assumed to be m, and m has no intersection with the wheel disc 21 or the lamp body 4. The inner wall of the first part 1a and the inner wall of the second part 1b are located on the side of m away from the axis of the impeller 2, or the inner wall of the first part 1a and the inner wall of the second part 1b coincide with m.

[0068] In some examples, such as Figure 5 As shown, in the reference plane, the first part 1a is a straight line, the second part 1b is a straight line, and the first part 1a and the second part 1b are collinear and coincide with the straight line m. That is, the inner wall of the housing 1 is a straight line, and α=180°. In this way, the inclination of the inner wall of the first part 1a is consistent with the inclination of the second part 1b, so that when the airflow flows along the first part 1a of the housing 1 to the second part 1b, the direction of the airflow does not change, thereby reducing the airflow loss, thereby making the fan light have a larger air volume and a longer air supply distance.

[0069] In some examples, such as Figure 6 As shown, the first part 1a is a straight line, the second part 1b is a straight line, and the second part 1b is bent relative to the first part 1a toward the guide vane area air duct 102, and α is less than 180°. In this way, when the airflow flows from the impeller area air duct 101 to the guide vane area air duct 102, it will only be slightly deflected along the inner wall of the shell 1, and the connection between the first part 1a and the second part 1b is not easy to block the airflow, so that the airflow loss is small, and then the air volume of the fan lamp is large and the air supply distance is long.

[0070] In some examples, such as Figure 7As shown, the first part 1a and the second part 1b are arc-shaped, and the inner wall of the housing 1 protrudes toward the outside of the fan lamp. When the airflow flows in the impeller area duct 101 and the guide vane area duct 102, the flow direction of the airflow will change slowly along the housing 1 without sudden changes, so the airflow loss is small.

[0071] Since the impeller area air duct 101 is composed of the inner wall of the first part 1a and the outer wall of the wheel disc 21, and the guide vane area air duct 102 is composed of the inner wall of the second part 1b and the outer wall of the lamp body 4, in addition to the shape of the inner wall of the housing 1 affecting the airflow loss, the shapes of the wheel disc 21 and the lamp body 4 also affect the airflow loss. The following is an exemplary description of the implementation of the wheel disc 21 and the lamp body 4:

[0072] In some examples, such as Figure 8-Figure 10 As shown, in the reference plane, assuming that the angle between the outer wall of the wheel disc 21 and the outer wall of the lamp body 4 is β, then 170°≤β≤180°. Therefore, when the airflow flows from the wheel disc 21 to the lamp body 4, the airflow is not easily blocked by the connection between the wheel disc 21 and the lamp body 4, so that the airflow can flow smoothly from the impeller area air duct 101 to the end of the guide vane area air duct 102, so that the airflow loss is small, thereby increasing the air supply range of the air outlet. Among them, β is the angle between the tangent line at the end of the outer wall of the wheel disc 21 and the tangent line at the top of the outer wall of the lamp body 4.

[0073] In some examples, such as Figure 8-Figure 10 As shown, in the reference plane, let the line connecting the top of the wheel disc 21 and the bottom of the lamp body 4 be n, the wheel disc 21 and the lamp body 4 are located on the side of n close to the axis of the impeller 2, or the outer wall of the wheel disc 21 and the outer wall of the lamp body 4 coincide with n.

[0074] In some examples, such as Figure 8 As shown, in the reference plane, the outer wall of the wheel disc 21 is a straight line, the outer wall of the lamp body 4 is a straight line, and the outer wall of the wheel disc 21 and the outer wall of the lamp body 4 are collinear and coincide with the straight line n, so β ​​= 180°. In this way, the inclination of the outer wall of the wheel disc 21 is consistent with the inclination of the outer wall of the lamp body 4, and the direction of the airflow does not change when the airflow flows along the outer wall of the wheel disc 21 to the outer wall of the lamp body 4, so that the airflow loss is small, and then the air volume of the fan lamp is large and the air supply distance is long.

[0075] In some examples, such as Fig. 9As shown, in the reference plane, the outer wall of the wheel disc 21 is a straight line, the outer wall of the lamp body 4 is a straight line, and the outer wall of the lamp body 4 is bent relative to the outer wall of the wheel disc 21 toward the guide vane area duct 102, so β<180°. In this way, when the airflow flows from the impeller area duct 101 to the guide vane area duct 102, it will only be slightly deflected along the outer wall of the wheel disc 21 and the outer wall of the lamp body 4, and it is not easy to block the airflow, so that the airflow loss is small, and then the air volume of the fan lamp is large and the air supply distance is long.

[0076] In some examples, such as Fig.10 As shown, in the reference plane, the outer wall of the wheel disc 21 is arc-shaped, the outer wall of the lamp body 4 is arc-shaped, and the outer wall of the wheel disc 21 and the outer wall of the lamp body 4 are on the same arc line, and the connection between the wheel disc 21 and the lamp body 4 protrudes in the direction away from the impeller area air duct 101. In this way, the airflow will be slowly deflected along the wheel disc 21 and the lamp body 4, so that the airflow loss is small.

[0077] In some examples, such as Figure 5 As shown, in the reference plane, the angle between the inner wall of the first part 1a and the vertical direction is α1, then 15°≤α1≤50°, and the angle between the inner wall of the second part 1b and the vertical direction is α2, then 15°≤α2≤50°. In this way, the angles between the first part 1a and the second part 1b and the vertical direction are small, which is conducive to the fan lamp blowing air downward.

[0078] In some examples, such as Figure 5 As shown, in the reference plane, the angle between the outer wall of the wheel 21 and the vertical direction is β1, then 0°≤β1-α1≤30°. In the reference plane, the angle between the outer wall of the lamp body 4 and the vertical direction is β2, then 0°≤β2-α2≤30°.

[0079] When β1-α1=0° and β2-α2=0°, the outer wall of the wheel 21 is parallel to the inner wall of the first part 1a, and the outer wall of the lamp body 4 is parallel to the inner wall of the second part 1b.

[0080] When β1-α1>0° and β2-α2>0°, the impeller area air duct 101 and the guide vane area air duct 102 gradually become narrower along the air flow direction, so that the air flow pressure gradually increases, making the wind pressure at the end of the guide vane area air duct 102 larger, which is beneficial to increase the air supply distance of the fan lamp.

[0081] In some examples, the boundary plane between the impeller area air duct 101 and the guide vane area air duct 102 is located between the plane where the bottom end of the wheel disk 21 is located and the plane where the upper edge of the guide vane 3 is located.

[0082] In some examples, such as Figure 5As shown, assuming that the diameter of the opening at the top of the housing 1 is D1 and the diameter of the opening at the bottom is D2, then 0.5≤D1 / D2≤0.85, thereby providing sufficient radial space for the impeller 2 to work.

[0083] If D1 / D2<0.5, D1 will be too small, so that the installation space of the impeller 2 is small, resulting in smaller blades 22 of the impeller 2, and further smaller air intake and air outlet of the fan lamp.

[0084] If D1 / D2>0.85, the wind pressure at the air outlet of the fan lamp will be relatively small, which is not conducive to increasing the air supply distance of the fan lamp.

[0085] In some examples, such as Figure 5 As shown, assuming that the diameter of the bottom of the lamp body 4 is D3 and the diameter of the opening at the bottom of the housing 1 is D2, then D3 / D2≤0.8, and an air outlet is formed between the bottom of the lamp body 4 and the bottom of the housing 1. Thus, the end of the guide vane area air duct 102 has a sufficient air outlet width, so that the air outlet of the fan lamp is large. If D3 / D2 is too large, the airflow in the guide vane area air duct 102 will be blocked, resulting in a large airflow loss.

[0086] In some examples, the lamp body 4 includes a lamp housing and a lamp bead, and the lamp bead is fixed inside the lamp housing.

[0087] In some other examples, the lamp body 4 includes a lamp cover shell and a lamp body, the lamp body includes a lamp housing and lamp beads, and the lamp body is installed inside the lamp cover shell.

[0088] In order to make the wind blown by the fan lamp cleaner, in some examples, such as Figure 1 , Figure 2 and Figure 4 As shown, the fan lamp further includes an air inlet outer cover 5 and a dust screen 6. The air inlet outer cover 5 and the dust screen 6 are fixed to the top of the housing 1, and the air inlet outer cover 5 surrounds the dust screen 6, and an ash falling channel 50 is provided between the air inlet outer cover 5 and the dust screen 6, and the ash falling channel 50 is connected to the impeller area air duct 101.

[0089] like Figure 1 , Figure 2 and Figure 4As shown, the air inlet outer cover shell 5 is coaxial with the shell 1, and the side wall of the air inlet outer cover shell 5 has through holes arranged in an array, so that the airflow enters from the side wall of the air inlet outer cover shell 5, and the air inlet outer cover shell 5 can block foreign matter in the airflow. The air inlet outer cover shell 5 is annular, and its diameter gradually decreases in the direction close to the shell 1, and the side wall of the air inlet outer cover shell 5 protrudes toward the dust screen 6. The inner diameter of the bottom end of the air inlet outer cover shell 5 is equal to the inner diameter of the shell 1, and the inner wall of the bottom end of the air inlet outer cover shell 5 is smoothly connected to the inner wall of the shell 1. In this way, after the air inlet outer cover shell 5 blocks the foreign matter, the foreign matter can directly fall from the outer wall of the air inlet outer cover shell 5, and then enter the inner wall of the shell 1, without being retained on the outer wall of the air inlet outer cover shell 5.

[0090] The dust screen 6 is annular, and the airflow passes through the air inlet outer shell 5 and then passes through the dust screen 6 to enter the impeller area air duct 101. After passing through the air inlet outer shell 5, the dust in the airflow will be blocked by the dust screen 6, so that the dust enters the impeller area air duct 101 through the dust falling channel 50, and will not be retained on the inner wall of the air inlet outer shell 5 or the outer wall of the dust screen 6. If dust accumulates on the air inlet outer shell 5 and the dust screen 6, a large amount of dust may fall at the same time under the action of wind, so that the wind blown out by the fan light contains more dust.

[0091] In some examples, such as Figure 5-Figure 7 As shown, in the reference plane, assuming that the angle between the outer wall of the first part 1a and the outer wall of the second part 1b is ω, then 180°≤ω≤190°. Wherein, ω is the angle between the tangent line at the end of the outer wall of the first part 1a and the tangent line at the top of the outer wall of the second part 1b, and the end of the first part 1a and the top of the second part 1b are the connection points of the first part 1a and the second part 1b.

[0092] In some examples, such as Figure 5-Figure 7 As shown, in the reference plane, let the line connecting the top and bottom ends of the outer wall of the casing 1 be a, the outer wall of the first part 1a and the outer wall of the second part 1b are located on the side of a away from the axis of the impeller 2, or the outer wall of the first part 1a and the outer wall of the second part 1b coincide with a.

[0093] In some examples, such as Figure 5 As shown, the outer wall of the first part 1a is a straight line, the outer wall of the second part 1b is a straight line, and the first part 1a and the second part 1b are collinear, that is, the outer wall of the housing 1 is a straight line, and ω=180°. In this way, when there is dust on the outer wall of the housing 1, the dust can roll down along the outer wall of the housing 1, so that the outer wall of the housing 1 is not easy to accumulate dust.

[0094] In some examples, such as Figure 6As shown, the outer wall of the first part 1a is a straight line, the outer wall of the second part 1b is a straight line, and the second part 1b is bent relative to the first part 1a toward the inner wall of the guide vane area air duct 102. In this way, when the dust on the outer wall of the first part 1a rolls down to the connection between the first part 1a and the second part 1b, it will not fall to the outer wall of the second part 1b, but will fall directly.

[0095] In some examples, such as Figure 7 As shown, the outer wall of the first part 1a is arc-shaped, the outer wall of the second part 1b is arc-shaped, and the outer wall of the first part 1a and the outer wall of the second part 1b are on the same arc line, and the outer wall of the housing 1 protrudes toward the outside of the fan lamp. In this way, when the dust on the outer wall of the first part 1a rolls down to the connection between the first part 1a and the second part 1b, it will not fall to the outer wall of the second part 1b, but will fall directly.

[0096] In some examples, such as Figure 5 As shown, in the reference plane, the angle between the outer wall of the first part 1a and the vertical direction is ω1, then 15°≤ω1≤50°. The angle between the outer wall of the second part 1b and the vertical direction is ω2, then 15°≤ω2≤50°. In this way, the angles between the outer wall of the first part 1a and the outer wall of the second part 1b and the vertical direction are small, which is conducive to the dust on the outer wall of the shell 1 rolling down, so that the outer wall of the shell 1 is not easy to accumulate dust.

[0097] It should be noted that the shape of the outer wall of the housing 1 can be consistent with the shape of the inner wall, that is, the outer wall and the inner wall of the housing 1 are parallel (such as Figure 5-Figure 7 Alternatively, the shapes of the outer wall and the inner wall of the housing 1 may be different, for example, Figure 8 As shown, the outer wall of the housing 1 is arc-shaped, and the inner wall of the housing 1 is straight. This embodiment of the present disclosure does not specifically limit this.

[0098] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
