Abstract

The present disclosure belongs to the technical field of household appliances and provides a ceiling fan and a fan lamp. The ceiling fan comprises a shell, a fan assembly and a plurality of shielding tongues. The shell has an air inlet and is provided with an annular opening at the bottom. The fan assembly is located in the shell. The plurality of shielding tongues surround the fan assembly and divide the annular opening into a plurality of air outlets. Each shielding tongue has an air guide surface, the air guide surface facing the fan assembly. In the rotating direction of the fan assembly, each air guide surface successively comprises a first air guide part and a second air guide part, the second air guide part being in an arc shape, and a convex surface of the second air guide part facing the fan assembly. Thus, on one hand, the shielding tongues partially shield the annular opening, so as to increase the air volume of each air outlet. On the other hand, the air guide surfaces of the shielding tongues can guide air towards the air outlets, and the second air guide parts can more deflect the air-out direction of the air outlets towards the radial direction of the ceiling fan, allowing the ceiling fan to have a long air blowing distance.

DETAILED DESCRIPTION

[0102] An embodiment of the present disclosure provides a ceiling fan. As shown in FIG1 , the ceiling fan includes a housing 1, a fan assembly 2, and a plurality of shielding tongues 3. As shown in FIG2 , the housing 1 has an air inlet 11. As shown in FIG3 , the bottom of the housing 1 has an annular opening 12. As shown in FIG4-6 , the fan assembly 2 is located within the housing 1. The plurality of shielding tongues 3 surround the fan assembly 2 and divide the annular opening 12 into a plurality of air outlets 120.

[0103] The central axis of the annular opening 12, the central axis of the fan assembly 2, and the central axis of the entire ceiling fan are collinear. The annular opening 12 can also be understood as a plurality of air outlets 120 arranged in a circular pattern. As shown in Figures 5-8, the shielding tongues 3 partially shield the annular opening 12, and the shielding tongues 3 are spaced apart from the air outlets 120. The number of shielding tongues 3 can be equal to the number of air outlets 120.

[0104] According to the technical solution provided by the embodiment of the present disclosure, the shielding tongue 3 partially shields the annular opening 12 , while the air output of the fan assembly 2 remains unchanged, thereby increasing the air output of each air outlet 120 and further increasing the wind force of each air outlet 120 .

[0105] In some examples, as shown in Figures 5 and 6, the shielding tongue 3 has a first wind guide surface 31, which faces the fan assembly 2, and along the rotation direction of the fan assembly 2, the distance between the first wind guide surface 31 and the central axis of the annular opening 12 gradually increases.

[0106] The technical solution provided by the disclosed embodiment gradually increases the distance between the first air-guiding surface 31 of the shielding tongue 3 and the central axis of the annular opening 12, thereby enabling the first air-guiding surface 31 to concentrate the wind blown out by the fan assembly 2 to the air outlet 120. This results in a stronger wind force at each air outlet 120, thereby enabling the air outlet 120 to deliver air over a longer distance and a wider air supply range.

[0107] In some examples, as shown in Figures 1 and 4, the housing 1 includes an outer shell 101 and an inner shell 102, with the outer shell 101 surrounding the inner shell 102. The outer shell 101 has an air inlet 11, and an annular opening 12 is formed between the bottom of the outer shell 101 and the bottom of the inner shell 102. The ceiling fan can be circular.

[0108] In some examples, as shown in FIG1 , the top of the outer shell 101 has an air inlet 11. In other examples, the sidewall of the outer shell 101 has an air inlet 11. In other examples, the bottom of the inner shell 102 has an air inlet 11, and the fan assembly 2 draws air from the bottom of the inner shell 102. In this case, the fan can be directly connected to the ceiling as a ceiling fan.

[0109] In some examples, as shown in Figures 5 and 6 , along the rotation direction of the fan assembly 2, the first air guide surface 31 includes a first air guide portion 311 and a second air guide portion 312. The first air guide portion 311 and the second air guide portion 312 may also be referred to as a first air guide sub-surface and a second air guide sub-surface. The second air guide portion 312 and the first air guide portion 311 are described below in exemplary embodiments.

[0110] (1) Second air guide 312

[0111] In some examples, as shown in FIG. 5 to FIG. 8 , the second air guide portion 312 is arc-shaped, and the convex surface of the second air guide portion 312 faces the fan assembly 2 .

[0112] Through the above arrangement, on the one hand, the second air guide portion 312 can deflect the flow direction of the wind toward the radial direction of the fan assembly 2. In this way, the wind has a larger radial component after being blown out from the air outlet 120, which is conducive to the outward expansion of the wind direction, thereby increasing the air supply distance of the ceiling fan. On the other hand, the retraction of the end of the second air guide portion 312 can reduce the central angle occupied by the shielding tongue 3 without reducing the air guide length of the first air guide surface 31. That is, the central angle occupied by the air outlet 120 is larger. In this way, the wind blown out of the annular opening 12 can be continuous, that is, the air outlet of the annular opening 12 is more uniform.

[0113] In other examples, the second air guide portion 312 may not have a convex surface (for example, the second air guide portion 312 is a plane). In this case, as long as the second air guide portion 312 retracts relative to the extension surface of the first air guide portion 311 (as shown in FIG. 6 ), the above-mentioned effect can still be achieved.

[0114] In some examples, as shown in FIG6 , in a reference plane perpendicular to the central axis of the annular opening 12 , an angle between a tangent line at the end of the second air guide portion 312 and a line connecting the end of the second air guide portion 312 and the central axis of the annular opening 12 is ω, and 0°<ω<20°.

[0115] In this way, the angle between the airflow at the end of the second air guide 312 and the radial direction of the annular opening 12 can be made smaller, which is beneficial for increasing the air supply distance of the ceiling fan.

[0116] Figure 9 is a schematic diagram showing the angle ω and the shielding area of ​​the annular opening 12 by the shielding tongue 3. The horizontal axis represents the angle ω between the end of the second air guide portion 312 and the central axis of the annular opening 12, in degrees. The vertical axis represents the shielding area of ​​the annular opening 12 by the shielding tongue 3, in m. 2 As can be seen from FIG9 , as ω increases, the shielding area of ​​the annular opening 12 by the shielding tongue 3 gradually increases.

[0117] Figure 10 is a schematic diagram showing the relationship between the angle ω and the wind pressure at the air outlet 120. The horizontal axis represents the angle ω between the end of the second air guide 312 and the central axis of the annular opening 12, in degrees. The vertical axis represents the wind pressure at the air outlet 120, in Pa. As can be seen from Figure 10, as ω increases, the wind pressure at the air outlet 120 gradually increases, and the blowing distance of the air outlet 120 also gradually increases.

[0118] From Figures 9 and 10, it can be seen that if ω>20°, on the one hand, the area of ​​the annular opening 12 blocked by the second air guide 312 is further increased, thereby reducing the area of ​​the air outlet 120 and increasing the wind pressure at each air outlet 120. However, since the portion of the annular opening 12 corresponding to the shielding tongue 3 does not emit air, the pressure difference of the airflow at different parts of the annular opening 12 is large, which in turn makes the air outlet of the annular opening 12 obviously uneven, resulting in significantly different wind forces felt by users at different positions. On the other hand, this will cause the angle between the wind direction at the end of the second air guide 312 and the radial direction of the housing 101 to be larger. When the airflow passes through the housing 101 and flows to the air outlet 120, the rotation direction of the airflow is larger, causing the airflow to rotate below the air outlet 120, making it difficult to blow from the air outlet 120 to a farther distance.

[0119] Furthermore, in some examples, 5°<ω<20°. This can prevent the curvature of the convex second air guide portion 312 from being too large, thereby preventing the airflow from flowing too fast in the second air guide portion 312. If the airflow flows too fast, it will easily converge toward the central axis of the annular opening 12, making it difficult to increase the air supply distance.

[0120] (2) First air guide portion 311

[0121] The first air guide portion 311 is used to guide the wind toward the second air guide portion 312. In some examples, as shown in Figures 6 to 8, the first air guide portion 311 is arc-shaped, and the concave surface of the first air guide portion 311 faces the fan assembly 2. The first air guide portion 311 is used to gather airflow. Along the rotation direction of the fan assembly 2, the angle between the tangent of the first air guide portion 311 and the radial direction of the annular opening 12 gradually decreases. In this way, when the airflow passes through the shielding tongue 3, it will first be concentrated at the first air guide portion 311, and then enter the air outlet 120 along the second air guide portion 312.

[0122] It should be noted that if the first air guide portion 311 is set to have a convex surface facing the fan assembly 2, the airflow will flow too fast in the first air guide portion 311 and the second air guide portion 312, and the airflow will easily gather in the direction of the central axis of the annular opening 12, making it difficult to increase the air supply distance.

[0123] In other examples, as shown in FIG11 , the distance between the first air guide portion 311 and the central axis of the annular opening 12 increases linearly along the rotation direction of the fan assembly 2. That is, the air guide surface of the first air guide portion 311 is flat. This prevents excessive airflow velocity in the first air guide portion 311, facilitating airflow concentration.

[0124] In some examples, as shown in FIG7 , when the first air guide portion 311 is curved, within a reference plane, let r1 be the distance between the head end of the first air guide portion 311 and the central axis of the annular opening 12, let r be the distance between the target point on the first air guide portion 311 and the central axis of the annular opening 12, and let r be the angle θ between the line connecting the head end of the first air guide portion 311 and the central axis of the annular opening 12 and the line connecting the target point and the central axis of the annular opening 12, r = (m1 + sinθ)r1 + m2. Here, m1 and m2 are constant coefficients, and the target point is any point on the first air guide portion 311.

[0125] In this way, the first air guide portion 311 can be made relatively flat, which is conducive to the first air guide portion 311 gathering airflow. The reference plane is perpendicular to the central axis of the annular opening 12, and the reference plane is located between the top and bottom surfaces of the fan assembly 2 and intersects with the fan assembly 2.

[0126] In some examples, as shown in FIG6 , assuming that the angle between the tangent line of the head end of the first air guide portion 311 and the line connecting the head end of the first air guide portion 311 and the central axis of the annular opening 12 is σ, then 10°<σ-ω<45°.

[0127] In this way, the deflection angle of the airflow on the entire first air guide surface 31 can be reduced, and the flow direction of the airflow can be prevented from changing significantly when the airflow flows along the first air guide surface 31, which is beneficial for reducing airflow loss. At the same time, it is also beneficial for the first air guide portion 311 to gather airflow.

[0128] In some examples, as shown in Figure 7, the distance between the end of the first air guide portion 311 and the central axis of the annular opening 12 is r2, and 1.015<r2 / r1<1.2, which is beneficial for the first air guide portion 311 to gather airflow, and also beneficial for the first air guide portion 311 to guide the airflow to the second air guide portion 312.

[0129] If r2 / r1 is too small, the radial component of the airflow will be small when the airflow passes through the first air guide 311, which may easily cause the airflow to rotate circumferentially around the fan assembly 2, making it difficult for the airflow to be blown out from the air outlet 120.

[0130] If r2 / r1 is too large, the airflow will flow too fast in the first air guide portion 311, causing the airflow to easily gather toward the center axis of the annular opening 12, making it difficult to increase the air supply distance.

[0131] In some examples, as shown in FIG. 7 , the radius of the fan assembly 2 is R, and r / R≥1.05, so that the head end of the first air guide portion 311 has sufficient air guide space, which is conducive to guiding the airflow to the second air guide portion 312 .

[0132] If r / R is too small, the gap between the head end of the first air guide part 311 and the edge of the impeller 22 will be smaller, and the air guide space at the head end of the first air guide part 311 will be smaller, making it difficult for the wind blown out by the fan assembly 2 to pass through the shielding tongue 3, making it easy for the air flow to backflow.

[0133] In some examples, as shown in Figures 6-8, at the connection between the first air guide portion 311 and the second air guide portion 312, the first air guide portion 311 and the second air guide portion 312 are tangent, so that the transition between the first air guide portion 311 and the second air guide portion 312 is smoother, thereby allowing the airflow to flow smoothly at the connection between the first air guide portion 311 and the second air guide portion 312.

[0134] In some examples, as shown in Figure 12, the shielding tongue 3 also has a second wind guide surface 32, the head end of the first wind guide surface 31 is connected to the head end of the second wind guide surface 32, and an air outlet 120 is provided between the second wind guide surface 32 of one shielding tongue 3 and the first wind guide surface 31 of the adjacent shielding tongue 3.

[0135] Among them, in the reference plane perpendicular to the central axis of the annular opening 12, the line between the head end of the first wind guide surface 31 (or the head end of the second wind guide surface 32) and the central axis of the annular opening 12 is set as the first reference line a, the line between the end of the first wind guide surface 31 and the central axis of the annular opening 12 is set as the second reference line b, and the line between the end of the second wind guide surface 32 and the central axis of the annular opening 12 is set as the third reference line c, then the third reference line c is located between the first reference line a and the second reference line b.

[0136] According to the technical solution provided by the embodiment of the present disclosure, the angle occupied by the first wind-guiding surface 31 of the shielding tongue 3 is the angle between the first reference line a and the second reference line b, and the angle occupied by the portion shielded by the shielding tongue 3 is the angle between the third reference line c and the second reference line b. Since the third reference line c is located between the first reference line a and the second reference line b, the angle occupied by the first wind-guiding surface 31 is greater than the angle occupied by the portion shielded by the shielding tongue 3.

[0137] This ensures that the shielding tongue 3 has a sufficiently long first air-guiding surface 31, while also shortening the portion shielded by the shielding tongue 3. This allows the ceiling fan to deliver air over a long distance, while also ensuring that the air blown out from each air outlet 120 is continuous in the circumferential direction, resulting in a more uniform annular air flow. Furthermore, this design also allows the second air-guiding surface 32 to be longer, providing a good air-guiding effect.

[0138] In some examples, assuming that the angle between the second reference line b and the third reference line c is α, then 20°<α<30°.

[0139] As shown in FIG13 , the horizontal axis represents α, in degrees, and the vertical axis represents the wind sensation radius, that is, the blowing radius that a user can feel when using the ceiling fan provided by the embodiment of the present disclosure, in meters.

[0140] As can be seen from Figure 13, as α increases, the wind-sensing radius also gradually increases. Since the wind-sensing radius is smaller when 0° < α < 20°, α > 20° can be set. When α > 30°, although the wind-sensing radius continues to increase, it will cause the shielding tongue 3 to block too much of the annular opening 12, making the air outlet 120 too small, resulting in uneven airflow from the ceiling fan. Therefore, in some examples, 20° < α < 30°.

[0141] In some examples, as shown in FIG12 , assuming the number of shielding tongues 3 is z, 130° / α<z<150° / α. That is, the angle covered by the shielding tongues 3 is at least 130° and at most 150°.

[0142] Experimental measurements show that if z < 130° / α, i.e., zα < 130°, the angle covered by the shielding tongues 3 is too small, resulting in a larger outlet area for each air outlet 120, making it difficult for the air outlet 120 to effectively increase wind pressure and force. This also shortens the length of the first and second air guide surfaces 31, 32, shortening the pressure-raising path of the airflow on these surfaces, hindering the increase in air pressure at the air outlet 120.

[0143] If z>150° / α, that is, zα>150°, the angle occupied by the total shielding portion of the multiple shielding tongues 3 is too large, which will cause the air outlet 120 to be too small. Although the air pressure at the air outlet 120 will be higher, since no air comes out from the shielding tongues 3, the wind blown out of the multiple air outlets 120 will be difficult to be continuous in the circumferential direction, making the annular air supply of the ceiling fan uneven.

[0144] In some examples, as shown in FIG12 , 4≤z≤6. For example, z=6.

[0145] In some examples, as shown in FIG12 , the central angle of each air outlet 20 is 40°-65°, and the sum of the central angles corresponding to the plurality of air outlets 120 is 220°-250°. This allows the ceiling fan to discharge air more evenly and with greater pressure.

[0146] In some examples, the sum of the central angles corresponding to the plurality of air outlets 120 is 210°-230°.

[0147] In some examples, as shown in FIG12 , within the reference plane, the angle between the first reference line a and the third reference line c is γ, and 0°<γ<15°. If γ is too large, the angle between the first air guide surface 31 and the second air guide surface 32 will be too small, making it difficult to process the shielding tongue 3. If γ is too small, the above-mentioned effect of more uniform annular air outlet cannot be achieved. In addition, the air outlet 120 will be too large, resulting in a smaller shielding portion of the shielding tongue 3, making it difficult to increase the air pressure at the air outlet 120, and further making it difficult to increase the air supply distance of the ceiling fan.

[0148] The above technical solution allows the air blown out of each air outlet 120 to be continuous in the circumferential direction, achieving a relatively uniform annular air output from the ceiling fan. Furthermore, the uniformity of the air blown out of each air outlet 120 also affects the uniformity of the annular air output. The following describes an exemplary method for improving the uniformity of the air blown out of each air outlet 120.

[0149] In some examples, as shown in FIG14 , within a reference plane, an angle δ is defined at the junction of the first air guide surface 31 and the second air guide surface 32, and δ is an acute angle. Setting δ to an acute angle allows the wind from the fan assembly 2 toward the shielding tongue 3 to partially flow along the first air guide surface 31 toward the portion of the air outlet 120 near the first air guide surface 31, and to partially flow along the second air guide surface 32 toward the portion of the other air outlet 120 near the second air guide surface 32.

[0150] Thus, for each air outlet 120, both the portion near the first air guide surface 31 and the portion near the second air guide surface 32 have a larger air volume, making the air outflow from the air outlet 120 more uniform. Alternatively, it can be described as follows: because the air outlet 120 is located between the second air guide surface 32 of one shielding tongue 3 and the first air guide surface 31 of the adjacent shielding tongue 3, the airflow within each air outlet 120 is partially derived from the first air guide surface 31 of one shielding tongue 3, and the other portion is derived from the second air guide surface 32 of the other shielding tongue 3. As a result, the air blown out of the air outlet 120 is more uniform.

[0151] As shown in Figure 15, when δ is an obtuse angle, on the one hand, under the premise of not changing the air guiding length of the first air guiding surface 31 and the second air guiding surface 32, δ being an obtuse angle will make the angle occupied by the part shielded by the shielding tongue 3 greater than the angle occupied by the first air guiding surface 31, resulting in a longer length of the part shielded by the shielding tongue 3, making the annular air outlet of the ceiling fan uneven.

[0152] On the other hand, this will also cause a greater impact between the air outlet of the fan assembly 2 and the second air guide surface 32, resulting in greater airflow impact loss. Because the first air guide surface 31 of the shielding tongue 3 is separated from the second air guide surface 32 of the adjacent shielding tongue by the air outlet 120, if δ is too large, the airflow near the first air guide surface 31 will be greater and the wind force will be stronger, while the airflow near the second air guide surface 32 will be less and the wind force will be weaker, resulting in uneven airflow at the air outlet 120.

[0153] In some examples, 9°<δ<38°. If δ is too small, the connection between the first air guide surface 31 and the second air guide surface 32 will not have an effective fillet radius, making the shielding tongue 3 difficult to manufacture, increasing the complexity and cost of manufacturing the ceiling fan.

[0154] In some examples, as shown in FIG16 , the angle between the tangent line at the head end of the first wind guide surface 31 and the first reference line a is φ, and φ>145°. This allows the angle between the wind blown by the fan assembly 2 and the first wind guide surface 31 to be smaller, thereby reducing the impact of the airflow on the first wind guide surface 31 and further reducing airflow losses. This makes the wind force at the air outlet 120 near the first wind guide surface 31 close to the wind force near the second wind guide surface 32, making the air outlet 120 more uniform.

[0155] In some examples, as shown in Figures 14 and 16, the second air-guiding surface 32 is arc-shaped, and the concave surface of the second air-guiding surface 32 faces the first air-guiding surface 31 of the shielding tongue 3, which is closest to the second air-guiding surface 32. Within the reference plane, along the rotation direction of the fan assembly 2, the angle between the tangent of the second air-guiding surface 32 and the radial direction of the annular opening 12 gradually decreases.

[0156] On the one hand, compared with the second wind guide surface 32 being straight (or a straight line), setting the second wind guide surface 32 to be arc-shaped can increase the length of the second wind guide surface 32, thereby increasing the pressurization path of the airflow, which is conducive to increasing the wind pressure. Since the length of the first wind guide surface 31 is longer, increasing the length of the second wind guide surface 32 can reduce the pressure difference between the end of the first wind guide surface 31 and the end of the second wind guide surface 32, thereby making the air outlet 120 more uniform. At the same time, it is also possible to reduce the central angle occupied by the shielding tongue 3 without reducing the air guide length of the first wind guide surface 31, even if the central angle occupied by the air outlet 120 is larger. In this way, the wind blown out of the annular opening 12 can be continuous, that is, the wind outlet of the annular opening 12 is relatively uniform. On the other hand, the second wind guide surface 32 can deflect the flow direction of the wind toward the radial direction of the fan assembly 2, so that the airflow has a larger radial component after flowing to the air outlet 120, which is conducive to the airflow blowing to a longer distance.

[0157] In some examples, as shown in FIG16 , within a reference plane, the angle between the tangent line at the end of the second air-guiding surface 32 and the line connecting the second air-guiding surface 32 and the central axis of the annular opening 12 is ε, and then 0°<ε<20°. This allows the angle between the wind direction at the end of the second air-guiding surface 32 and the radial direction of the annular opening 12 to be smaller, allowing the second air-guiding surface 32 to polarize the air outlet in the radial direction of the ceiling fan, thereby increasing the radial air delivery distance of the ceiling fan.

[0158] In some examples, as shown in FIG16 , in the reference plane, the line between the end of the first air guide portion 311 and the central axis of the annular opening 12 is the fourth reference line d, and the angle between the first reference line a and the fourth reference line d is β, and β<α.

[0159] If β > α, the length of the first air guiding part 311 will increase, resulting in a greater impact between the air flow and the first air guiding part 311, so that the resistance of the air blown by the fan assembly 2 is greater, and thus the load of the fan assembly 2 is increased.

[0160] In some examples, as shown in FIG. 17, the top of the shielding tongue 3 abuts against the outer shell 101, and / or the bottom of the shielding tongue 3 abuts against the inner shell 102, and along the air outlet direction, the dimension of the shielding tongue 3 in the vertical direction gradually decreases.

[0161] In the technical solution provided by the embodiment of the present disclosure, by setting the top of the shielding tongue 3 to abut against the outer shell 101, the bottom to abut against the inner shell 102, and along the air outlet direction, the dimension of the shielding tongue 3 in the vertical direction gradually decreases, so that the distance between the parts of the outer shell 101, the inner shell 102 and the shielding tongue 3 in contact also decreases. This makes the air duct through which the air flows gradually narrow during the air outlet process of the ceiling fan, and the air pressure gradually increases, which is beneficial to increasing the air supply distance of the ceiling fan.

[0162] In some examples, as shown in FIG. 17, the outer shell 101 includes a first arc portion 1011, and the inner shell 102 includes a second arc portion 1021. The concave surface of the first arc portion 1011 faces the convex surface of the second arc portion 1021, and a plurality of shielding tongues 3 are located between the first arc portion 1011 and the second arc portion 1021. In this way, the air flow blown by the fan assembly 2 can flow along the arc, making the air flow smoother and avoiding air flow loss caused by sudden change of the air flow direction.

[0163] In some examples, as shown in FIG. 5, both the top and the bottom of the shielding tongue 3 are arc-shaped and respectively fit with the first arc portion 1011 and the second arc portion 1021. Among them, the angle between the top of the shielding tongue 3, and / or the bottom of the shielding tongue 3 and the horizontal plane gradually increases along the air outlet direction. Since the air flow direction of the air blown by the fan assembly 2 is along the horizontal direction or close to the horizontal direction, and the ceiling fan needs to blow air downward, the angle between the bottom of the shielding tongue 3 and the horizontal plane gradually increases along the air outlet direction, which can gradually guide the air flow towards the vertical direction.

[0164] In some examples, as shown in FIG. 17, the maximum dimension of the shielding tongue 3 in the vertical direction is d1, and the minimum dimension in the horizontal direction is d2, 2.5 < d1 / d2 < 7. Further, 4 < d1 / d2 < 6. Here, d1 can also be understood as the dimension of the air duct 300 at the air inlet end, and d2 can also be understood as the dimension of the air duct 300 at the air outlet end (or the dimension of the air outlet 120). The air duct 300 is located between two adjacent shielding tongues 3.

[0165] Since the diameters of the outer shell 101 and the inner shell 102 are larger than the diameter of the fan assembly 2, if d1 / d2 is too small, the ventilation area of ​​the annular opening 12 (the ventilation area between the end of the first arc-shaped portion 1011 and the end of the second arc-shaped portion 1021) may still be larger than the ventilation area of ​​the edge of the fan assembly 2. This will result in the gap between the outer shell 101 and the inner shell 102 gradually decreasing, but the flow area between the outer shell 101 and the inner shell 102 gradually increasing, so that the wind pressure will gradually decrease, causing the flow velocity of the airflow in the air duct 300 to gradually decrease, making it easy for the airflow to generate vortices in the air duct 300, resulting in a shorter air supply distance of the annular opening 12.

[0166] If d1 / d2 is too large, although the ventilation area of ​​the annular opening 12 will be smaller than the ventilation area of ​​the edge of the fan assembly 2, the excessively small annular opening 12 will hinder the airflow, causing the air output at the annular opening 12 to be too small, which is not conducive to increasing the air supply distance.

[0167] In some examples, as shown in FIG17 , at the annular opening 12 , the angle between the end of the first arc portion 1011 and the vertical direction is β1, the angle between the end of the second arc portion 1021 and the vertical direction is β2, and β1<β2.

[0168] As shown in Figure 18 , the angle between the wind direction at the end of the first curved portion 1011 and the vertical direction is smaller than the angle between the wind direction at the end of the second curved portion 1021 and the vertical direction. The wind at the end of the first curved portion 1011 blocks the wind at the end of the second curved portion 1021 horizontally to a certain extent, thereby preventing the wind at the end of the second curved portion 1021 from spreading too quickly horizontally, resulting in a shorter air delivery distance. Furthermore, the overlap of the wind at the end of the first curved portion 1011 and the wind at the end of the second curved portion 1021 increases the wind pressure, thereby increasing the air delivery distance of the fan.

[0169] As shown in Figure 19, if β1>β2, the angle between the wind direction at the end of the first curved portion 1011 and the horizontal direction is smaller, causing the wind to spread outward in the horizontal direction. The angle between the wind direction at the end of the second curved portion 1021 and the vertical direction is smaller. The wind at the end of the first curved portion 1011 cannot block the wind at the end of the second curved portion 1021 in the horizontal direction. As a result, the wind along the ends of the first curved portion 1011 and the second curved portion 1021 spreads faster, resulting in a shorter blowing distance. In addition, the wind from the two directions does not overlap, resulting in a weaker wind force.

[0170] In some examples, 16°<β1<β2<35°, so that the ceiling fan can supply air over a longer distance in both the vertical and horizontal directions.

[0171] FIG20 is a graph showing the relationship between β1 and wind-sensing area. The horizontal axis represents β1, in degrees. The vertical axis represents the wind-sensing area, i.e., the area of ​​air that a user can feel when using the ceiling fan provided by the embodiment of the present disclosure, in m. 2 .

[0172] As can be seen from Figure 20, as β1 increases, the wind-sensing area first increases and then decreases. When 16° < β1 < 35°, the wind-sensing area is larger. Therefore, the setting is 16° < β1 < β2 < 35°.

[0173] If β1 and β2 are too large, the angles between the first and second curved portions 1011, 1021, and the horizontal direction are small. Since the airflow direction of the fan assembly 2 is close to the horizontal direction, the angles between the first and second curved portions 1011, 1021, and the airflow direction of the fan assembly 2 are small. This results in a small deflection angle of the airflow from the fan assembly 2 into the annular opening 12, resulting in excessive wind speed and difficulty in blowing the airflow far. Furthermore, this also causes the vertical component of the airflow at the annular opening 12 to be too small, resulting in weak vertical wind force and a short air delivery distance.

[0174] If β1 and β2 are too small, on the one hand, the horizontal component of the airflow at the annular opening 12 will be small, thereby reducing the horizontal air supply range of the ceiling fan. On the other hand, the deflection angle of the airflow from the fan assembly 2 to the first curved portion 1011 and the second curved portion 1021 will be too large, resulting in large airflow losses. The wind force of the airflow when it reaches the annular opening 12 is relatively small, which is not conducive to increasing the air supply distance of the airflow.

[0175] In some examples, as shown in FIG17 , the distance between the first arc-shaped portion 1011 and the second arc-shaped portion 1021 gradually decreases along the air outlet direction. This allows the airflow area to gradually decrease as it flows from the edge of the fan assembly 2 toward the annular opening 12, thereby increasing the air pressure and force of the airflow. This results in a stronger force when the airflow reaches the annular opening 12, thereby increasing the air supply distance and range of the ceiling fan.

[0176] The embodiment of the present disclosure does not limit the connection position between the shielding tongue 3 and the shell 1 . The shielding tongue 3 can be connected to the outer shell 101 or the inner shell 102 .

[0177] In some examples, as shown in FIG21 , the shielding tongue 3 is integrally injection-molded with the housing 101. The housing 101 wall is recessed to form the shielding tongue 3, and the outer wall of the housing 101 has a recessed portion 1012 corresponding to the portion of the shielding tongue 3. This strengthens the connection between the shielding tongue 3 and the housing 101, making it less likely to fall off. Furthermore, since the shielding tongue 3 and the housing 101 are integrally structured, no additional connecting components are required to connect the shielding tongue and the housing 101, thereby reducing the number of components and assembly steps required for the ceiling fan.

[0178] In some examples, as shown in FIG5 , the bottom of the shielding tongue 3 has a first accommodating cavity 30. A first mounting structure 301 is provided at the bottom of the first accommodating cavity 30. The first mounting structure 301 is configured to be fixedly connected to the inner housing 102. Because the airflow generated by the fan assembly 2 does not flow out of the annular opening 12 opposite the shielding tongue 3, placing the first mounting structure 301 within the first accommodating cavity 30 does not obstruct the flow of air, thereby reducing airflow losses and facilitating an increase in the air delivery distance and range of the ceiling fan.

[0179] The first mounting structure 301 can be a threaded hole. Accordingly, as shown in FIG22 , the inner housing 102 is provided with a second mounting structure 1022 , such as a through hole or a threaded hole. The first mounting structure 301 and the second mounting structure 1022 can be connected using bolts or screws, thereby securely connecting the inner housing 102 to the shielding tongue 3 and, in turn, to the outer housing 101.

[0180] In some examples, as shown in FIG21 , the bottom of the recessed portion 1012 has a wiring hole 10121 for passing the power cord through. In this way, the power cord does not pass through the air duct 300 and the air outlet 120, thereby not obstructing the air flow at the air outlet 120.

[0181] In some examples, to reduce noise, the shielding tongue 3 is provided with sound-absorbing holes, wherein the sound-absorbing holes are located on the first air-guiding surface 31 and / or the second air-guiding surface 32. For example, the sidewalls of the recessed portion 1012 may be provided with sound-absorbing holes.

[0182] In some examples, the outer wall of the housing 101 is covered with sound-absorbing cotton to reduce the noise generated by the air flow.

[0183] It should be noted that, in some examples, the concave and convex surfaces referred to in the article refer to the general direction of the surface. In other embodiments, local convex surfaces may be set in the concave surface for other effects.

[0184] The following is an exemplary description of the implementation of the fan assembly 2.

[0185] In some examples, as shown in FIG4 , the fan assembly 2 includes a motor 21 and an impeller 22. The impeller 22 is connected to the motor 21 in a transmission manner, and the impeller 22 is opposite the air inlet 11. The fan assembly 2 can be a centrifugal fan or a diagonal flow fan. The motor 21 can be installed inside the housing 1, such as on the inner housing 102, or can be installed in the hanging cup 51 of the suspension assembly 5.

[0186] In some examples, as shown in Figures 23 and 24, the fan assembly 2 includes a first support plate 221, a second support plate 222, and blades 223. The blades 223 are fixed between the first support plate 221 and the second support plate 222, with the first support plate 221 being close to the housing 101. Assume that the angle between the edge of the first support plate 221 and the horizontal direction is α1, and the angle between the edge of the second support plate 222 and the horizontal direction is α2, and α1>α2. The first support plate 221 and the second support plate 222 can also be referred to as the first cover plate and the second cover plate.

[0187] As shown in FIG17 , since β1<β2, the angle between the airflow blowing toward the annular opening 120 along the first arc portion 1011 and the vertical direction is smaller than the angle between the airflow blowing toward the annular opening 120 along the second arc portion 1021 and the vertical direction.

[0188] If α1 = α2, the airflow near the first support plate 221 and the airflow near the second support plate 222 flow toward the first curved portion 1011 and the second curved portion 1021 at the same angle, resulting in a larger deflection angle of the airflow flowing from the first support plate 221 to the first curved portion 1011, which in turn causes greater airflow loss, resulting in weaker wind force near the first curved portion 1011, and thus a shorter air supply distance for the airflow near the first curved portion 1011. Furthermore, because the deflection angle of the airflow flowing from the edge of the second support plate 222 to the second curved portion 1021 is smaller and the airflow loss is less, the airflow near the second curved portion 1021 has a stronger wind force. This results in different strengths of the airflow near the first curved portion 1011 and the second curved portion 1021, which in turn causes uneven wind force along the radial direction of the annular opening 12.

[0189] The technical solution provided by the embodiments of the present disclosure, by setting α1>α2, can, on the one hand, reduce the deflection angle of the airflow from the edge of the first support plate 221 to the first curved portion 1011, thereby reducing airflow loss and ensuring that the airflow near the first curved portion 1011 has greater wind force and a longer air delivery distance. Furthermore, it can also ensure that the wind force and wind pressure of the airflow near the first curved portion 1011 and the airflow near the second curved portion 1021 of the annular opening 12 are closer, thereby making the radial airflow of the annular opening 12 more uniform.

[0190] In some examples, 16° < α2 < α1 < 35°. If α1 and α2 are too large, the airflow deflection angle at the edge of the fan assembly 2 after flowing toward the first curved portion 1011 and the second curved portion 1021 will be too small, causing the airflow to diffuse too quickly. After flowing out of the annular opening 12, the airflow will concentrate toward the central axis of the annular opening 12, which is not conducive to increasing the air supply range of the ceiling fan. It will also reduce the vertical component of the airflow at the annular opening 12, thereby reducing the vertical air supply distance of the ceiling fan.

[0191] If α1 and α2 are too small, the deflection angle of the airflow at the edge of the fan assembly 2 when flowing toward the annular opening 12 will be too large, causing the airflow to encounter greater resistance, resulting in greater airflow loss, and further leading to weaker wind force at the annular opening 12, thereby reducing the air supply distance of the fan assembly 2.

[0192] In some examples, as shown in FIG24 , the first support plate 221 is provided with an impeller inlet 2211. A plurality of blades 223 are spaced around the impeller inlet 2211 and connected to the first support plate 221. A second support plate 222 is connected to the side of the blades 223 facing away from the first support plate 221. A flow dispersion structure 2221 is provided on the second support plate 222. The flow dispersion structure 2221 is used to disperse the airflow between the blades 223 to reduce airflow pressure. The trailing edge 2231 is the edge of the blade 223 facing away from the impeller inlet 2211.

[0193] When the impeller 22 rotates at high speed, air can flow through the impeller air inlet 2211 provided on the first support plate 221 and into the space between the multiple blades 223. Under the action of centrifugal force, the airflow flows through the flow dispersion structure 2221 on the second support plate 222. The flow dispersion structure 2221 disperses the airflow to reduce the airflow pressure at that location, thereby reducing the frequency of the sound produced by the impeller 22 during operation. The airflow noise heard by the user is no longer sharp and piercing, but is relatively low, making it more comfortable to listen to and improving the user experience.

[0194] In some examples, as shown in Figure 24, the impeller air inlet 2211 is opened in the middle of the first support plate 221, and multiple blades 223 sandwiched between the first support plate 221 and the second support plate 222 are arranged around the center line of the impeller air inlet 2211. Since there are gaps between each blade 223, when the impeller 22 rotates at high speed, it will attract air from the impeller air inlet 2211 into the interior of the impeller 22, and the air flow will be diverted between each blade 223. The multiple air flows after diversion will flow to the trailing edge 2231 of the blade 223 under the action of centrifugal force and be pushed out by the blade 223, thereby achieving the effect of circumferential air outlet along the impeller 22.

[0195] The first support plate 221, the second support plate 222, and the blades 223 are fixedly connected. In some examples, the first support plate 221 and the blades 223 are detachably connected, and the second support plate 222 and the blades 223 are also detachably connected, and the connection method can be, for example, bolt connection, clamping, etc.

[0196] Of course, in other examples, the first support plate 221 and the blades 223, as well as the second support plate 222 and the blades 223, may be non-detachably connected, such as by welding, bonding, or an integral connection. Alternatively, in other examples of the present disclosure, a combination of detachable and non-detachable connection methods may be used between the first support plate 221 and the blades 223, as well as between the second support plate 222 and the blades 223. For example, the first support plate 221 and the plurality of blades 223 are snap-fitted, while the second support plate 222 and the plurality of blades 223 are integrally connected.

[0197] The diffuser structure 2221 is used to disperse the airflow, reducing the velocity or pressure of the airflow passing through the diffuser structure 2221, thereby improving the sound quality of the airflow noise at that location. Generally speaking, the airflow velocity and pressure at the trailing edge 2231 of the blade 223 are high, and therefore the airflow noise emitted has a high frequency and is relatively sharp and harsh in hearing. The technical solution provided by the embodiment of the present disclosure, by providing the diffuser structure 2221 on the second support plate 222, disperses the airflow between the multiple blades 223, and disperses and reduces the airflow pressure. As a result, the airflow noise emitted at the location of the diffuser structure 2221 has a relatively low frequency and a relatively low sound quality. This neutralizes the sound quality of the airflow noise emitted when the airflow passes through the trailing edge 2231 of the blade 223, making the sound heard by the user no longer sharp and harsh, and greatly improving the hearing experience.

[0198] It should be noted that in some examples, the diffuser structure 2221 is only provided on the second support plate 222, but not on the first support plate 221 and the blades 223. This is because the first support plate 221 has an impeller inlet 2211, which has high turbulence intensity. Providing the diffuser structure 2221 on the first support plate 221 may affect the main airflow and air intake. However, the blades 223 need to promote airflow, so providing the diffuser structure 2221 on the blades 223 would affect the main airflow and air outlet.

[0199] In some examples, the flow dispersion structure 2221 is a hole structure. As shown in FIG26 , the second support plate 222 is provided with a plurality of through holes that penetrate the second support plate 222 . When the airflow passes through these locations, a small amount of the airflow is discharged and dispersed through the through holes, thereby achieving the effect of reducing the airflow pressure.

[0200] As shown in FIG25 , in the embodiment of the present disclosure, the second support plate 222 includes a hub portion 2222 and a blade connection portion 2223, wherein the blade connection portion 2223 surrounds the hub portion 2222. The hole structure includes at least one of a first through hole 22211 and a second through hole 22212, wherein the first through hole 22211 is provided on the hub portion 2222, and the second through hole 22212 is provided on at least a portion of the blade connection portion 2223.

[0201] The hub portion 2222 is used to mount the drive shaft of the motor 21. The impeller 22 is configured to rotate at high speeds driven by the motor 21. The blade connecting portion 2223 is the portion of the second support plate 222 that is used to connect to the blades 223. This portion is typically connected to the outer periphery of the hub portion 2222 and is arranged in an annular shape.

[0202] The hole structure may be provided in the entire area of ​​the second support plate 222, or only in a portion of the second support plate 222. In some examples, the hole structure is provided in the hub portion 2222 and in at least a portion of the blade connection portion 2223. The hole structure provided in the hub portion 2222 is defined as a first through hole 22211, and the hole structure provided in the blade connection portion 2223 is defined as a second through hole 22212.

[0203] In some examples, as shown in FIG26 , the blade connection portion 2223 includes a first sub-portion 22231 and a second sub-portion 22232. The first sub-portion 22231 is connected to the outer periphery of the hub portion 2222 and has a second through-hole 22212 defined therein. The second sub-portion 22232 is connected to the edge of the first sub-portion 22231 away from the hub portion 2222. Along the radius of the impeller 22, the ratio of the width of the first sub-portion 22231 to the width of the second sub-portion 22232 ranges from 0.6 to 1.

[0204] Continuing with FIG26 , the first subsection 22231 and the second subsection 22232 are sequentially connected along the radius of the impeller 22. The first subsection 22231 is connected to the hub 2222, and the leading edge 2232 of the blade 223 is located on the portion of the blade connected to the first subsection 22231. The second subsection 22232 is connected to the side of the first subsection 22231 away from the hub 2222, and the trailing edge 2231 of the blade 223 is located on the portion of the blade connected to the second subsection 22232. The leading edge 2232 and the trailing edge 2231 of the blade 223 are opposite edges. Generally speaking, both the first subsection 22231 and the second subsection 22232 have an annular structure.

[0205] In the embodiment of the present disclosure, the arrangement of the diffuser structure 2221 needs to ensure that it does not affect the inlet and outlet of air, as well as the flow of the main airflow. Since the hub portion 2222 does not do work during the high-speed rotation of the impeller 22, the opening of the hole in the hub portion 2222 has little effect on the airflow. The first sub-portion 22231 of the blade connection portion 2223 is the starting section for work, where the airflow pressure has not yet reached the maximum value. When the pressure is discreted, its performance attenuation is relatively controllable, so the first sub-portion 22231 can also be opened. However, the airflow pressure at the second sub-portion 22232 of the blade connection portion 2223 is relatively high, and the blade 223 has a strong work capacity and does a lot of work, so the second sub-portion 22232 cannot be opened to ensure a stable outflow of the airflow.

[0206] In the disclosed embodiment, the width of the first sub-section 22231 should not be greater than the width of the second sub-section 22232 to prioritize stable outflow of the airflow. In some examples, the ratio of the width of the first sub-section 22231 to the width of the second sub-section 22232 is 0.6, 0.8, or 1. For example, as shown in FIG26 , the ratio of the width H1 of the first sub-section 22231 to the width H2 of the second sub-section 22232 is 1, that is, the width H1 of the first sub-section 22231 and the width H2 of the second sub-section 22232 are equal, wherein the width direction is parallel to the radius direction of the impeller 22.

[0207] In some examples, as shown in FIG27 , the orthographic projection of the hub portion 2222 on the projection plane is located within the orthographic projection of the impeller air inlet 2211 on the projection plane, and the orthographic projection of at least a portion of the first sub-portion 22231 on the projection plane is located within the orthographic projection of the impeller air inlet 2211 on the projection plane. The projection plane is perpendicular to the opening direction of the impeller air inlet 2211.

[0208] Figure 27 shows the orthographic projection of an impeller 22 provided by an embodiment of the present disclosure on a projection plane. As shown in Figure 27, on the projection plane, the orthographic projection of the first support plate 221 completely overlaps with the orthographic projection of the second subsection 22232 of the second support plate 222, and partially overlaps with the orthographic projection of the first subsection 22231. The orthographic projection of the impeller air inlet 2211 completely overlaps with the orthographic projection of the hub portion 2222, and partially overlaps with the orthographic projection of the first subsection 22231. Therefore, the first support plate 221 covers the portion of the first subsection 22231 away from the hub portion 2222, preventing sound waves from rebounding.

[0209] In some examples, as shown in FIG25 , the hole area of ​​the first through hole 22211 is greater than or equal to the hole area of ​​the second through hole 22212. As described above, since the opening of the hub portion 2222 has little effect on the airflow, the hole area of ​​the first through hole 22211 can be as large as possible while ensuring the mechanical properties of the hub portion 2222, such as the connection strength and rigidity. As shown in FIG25 , the hub portion 2222 is provided with eight first through holes 22211 in an annular direction, and the first sub-portion 22231 is provided with a plurality of second through holes 22212 (generally more than the number of first through holes 22211), and the hole area of ​​each first through hole 22211 is much larger than the hole area of ​​any second through hole 22212.

[0210] In the embodiment of the present disclosure, there are multiple second through holes 22212, and the hole area of ​​each second through hole 22212 can be set according to actual needs. In some examples, the hole areas of the multiple second through holes 22212 are equal.

[0211] In other examples, along the extension direction of the blade 223, the further away from the hub portion 2222 are the second through holes 22212, the smaller the hole area. The second through holes 22212 that are farther from the hub portion 2222 are located at a location where the blade 223 performs a relatively greater amount of work, and thus, to avoid affecting the airflow, the hole area is relatively smaller.

[0212] In the embodiment of the present disclosure, the shape of each second through hole 22212 can be set according to actual needs. The shape of the second through hole 22212 can include at least one of the following: a bar hole, a round hole, a square hole, a rectangular hole, a hexagonal hole, a special-shaped hole, and a special pattern hole. In addition, the shape of the first through hole 22211 can be the same as the shape of the second through hole 22212, or it can be different from the shape of the second through hole 22212. As shown in Figure 25, the first through hole 22211 is a bar hole, and the second through hole 22212 is a round hole. In some examples, when the second through hole 22212 is a round hole, the diameter of the round hole is not greater than 2 mm.

[0213] In the disclosed embodiment, the arrangement of the second through-holes 22212 can be customized based on actual needs. For example, as shown in Figures 26 and 28 , the first subsection 22231 includes multiple airflow zones 222311 distributed along the circumferential direction of the impeller 22, with two adjacent airflow zones 222311 separated by a blade 223. The second through-holes 22212 are evenly distributed throughout the multiple airflow zones 222311. Furthermore, referring to Figure 26 , the multiple second through-holes 22212 in each airflow zone 222311 are arranged in multiple rows, with the row direction parallel to a set line L1, which passes through the same position on the leading edge 2232 of each of the two blades 223 adjacent to the airflow zone 222311. In Figure 26 , the set line L1 is parallel to a line L2 passing through the center of a row of second through-holes 22212.

[0214] Furthermore, when the impeller 22 is in operation, air flows out from different heights of the blades 223, where the height direction refers to the direction from the second support plate 222 to the first support plate 221. However, since the air flows out from different heights take different paths, the air flow near the first support plate 221 generally has a shorter flow path within the impeller 22 than the air flow near the second support plate 222. This results in inconsistent airflow velocities at different parts of the trailing edge 2231 of the blade 223, which can easily generate vortices at the trailing edge 2231.

[0215] In some examples, as shown in Figures 24 and 28, at least a portion of the trailing edge 2231 of the blade 223 is a vortex-breaking trailing edge 2231. The vortex-breaking trailing edge 2231 is used to suppress the formation of a shedding vortex at the trailing edge 2231 and to weaken a shedding vortex that has already formed at the trailing edge 2231. By using the vortex-breaking trailing edge 2231, the formation of a vortex at the trailing edge 2231 of the blade 223 can be avoided, thereby improving the outflow stability of the impeller 22 and reducing airflow noise.

[0216] In some examples, the vortex breaker trailing edge 2231 has at least one of the following shapes: sawtooth, corrugated, pyramidal, conical, hooked, tree-branched, stalactite-shaped, and ice-shaped. FIG29 shows a sawtooth-shaped vortex breaker trailing edge 2231 .

[0217] As shown in FIG. 29 , in some examples, the vortex breaking trailing edge 2231 is serrated and points from the first support plate 221 to the second support plate 222 , and the tooth widths of the plurality of serrations 22311 on the vortex breaking trailing edge 2231 gradually increase.

[0218] Because the flow path of the airflow outflowing near the first support plate 221 within the impeller 22 is relatively short, while the flow path of the airflow outflowing near the second support plate 222 within the impeller 22 is relatively long, if a shedding vortex is generated by the trailing edge 2231 of the blade 223 near the first support plate 221, the scale of this shedding vortex must be smaller than the vortex generated by the trailing edge 2231 of the blade 223 near the second support plate 222. To weaken this shedding vortex, when using the serrated vortex-breaking trailing edge 2231 to disperse the vortex, the larger the vortex scale, the larger the tooth width of the serration 2231 corresponding to the vortex should be.

[0219] 29 , the tooth width s1 of the sawtooth 22311 close to the first support plate 221 is smaller than the tooth width s2 of the sawtooth 22311 close to the second support plate 222 , and the tooth width of each sawtooth 22311 increases sequentially from the first support plate 221 to the second support plate 222 .

[0220] In some examples, the ratio of the tooth width of the saw tooth 22311 closest to the second support plate 222 to the tooth width of the saw tooth 22311 closest to the first support plate 221 ranges from 1.5 to 1.8, that is, s2:s1=1.5 to 1.8.

[0221] In some examples, as shown in FIG30 , the height of the blade 223 gradually decreases from the leading edge 2232 to the trailing edge 2231 of the blade 223. Also, as shown in FIG26 , the distance between the leading edges 2232 of two adjacent blades 223 is smaller than the distance between the trailing edges 2231 of two adjacent blades 223.

[0222] Multiple blades 223 are evenly distributed between the first support plate 221 and the second support plate 222, and for any two adjacent blades 223 among the multiple blades 223, as shown in Figure 26, the distance d3 between the leading edges 2232 of the two blades 223 is smaller than the distance d4 between the trailing edges 2231 of the two blades 223.

[0223] Each blade 223 has a lower height as it approaches the trailing edge 2231 of the blade 223, thereby compressing and concentrating the airflow and increasing the outflow velocity and outflow distance of the airflow. In some examples, the blade 223 is a spiral blade having a curved surface to guide the airflow.

[0224] To ensure clean air, as shown in FIG31 , in some examples, the ceiling fan further includes an annular filter element 4, which is located at the air inlet 11 of the housing 1 and is used to filter the airflow entering the housing 1. The annular filter element 1 has a grid structure.

[0225] In some examples, as shown in FIG31 , the area enclosed by the cross section of the annular filter element 4 gradually decreases in a direction away from the interior of the housing 1 .

[0226] In some examples, as shown in FIG. 31 to FIG. 33 , the annular filter element 4 includes a first filter element 41 and a second filter element 42 , and the first filter element 41 and the second filter element 42 are detachably connected.

[0227] The technical solution provided by the embodiment of the present disclosure is to set the annular filter element 4 as a first filter element 41 and a second filter element 42 that can be detachably connected. When the annular filter element 4 is disassembled or installed, it is only necessary to separate or combine the first filter element 41 and the second filter element 42 accordingly. The operation is simple and convenient, and the work efficiency is improved.

[0228] In some examples, as shown in FIG31 , the annular filter 4 is recessed into the interior of the housing 1, and / or the spacing between the annular filter 4 and the housing 1 along the central axis of the housing 1 increases as the distance between the annular filter 4 and the bottom of the housing 1 (e.g., the light module 6) increases. This arrangement allows for a smooth transition between the annular filter 4 and the housing 1, making the fan light more aesthetically pleasing.

[0229] In some examples, as shown in Figure 32, the first filter element 41 is a curved plate having a plurality of first openings 411, and the second filter element 42 is a curved plate having a plurality of second openings 421. This facilitates the annular filter element 4 to achieve a filtering function.

[0230] In some examples, each first opening 411 has the same structure, and the spacing between two adjacent first openings 411 is the same. Each second opening 421 has the same structure, and the spacing between two adjacent second openings 421 is the same. This arrangement facilitates processing and manufacturing.

[0231] In some examples, as shown in FIG. 32 and FIG. 33 , the size of the first filter element 41 is the same as the size of the second filter element 42 to facilitate manufacturing.

[0232] In some examples, the size of the first filter element 41 is different from the size of the second filter element 42. For example, the size of the first filter element 41 is larger than the size of the second filter element 42, or the size of the first filter element 41 is smaller than the size of the second filter element 42. As long as it can be ensured that the first filter element 41 and the second filter element 42 can form a complete annular structure when they are relatively fitted together, it will be sufficient.

[0233] In some examples, as shown in Figures 32 and 33, the first opening 411 and the second opening 421 are both strip-shaped holes, and the opening size of the strip-shaped holes gradually increases from the end away from the housing 1 to the end close to the housing 1. This arrangement reduces wind resistance when air enters the fan light through the first opening 411 and the second opening 421.

[0234] In some examples, as shown in FIG33 , one end of the first filter element 41 has a first connecting plate 412, and one end of the second filter element 42 has a third connecting plate 422, and the first connecting plate 412 and the third connecting plate 422 are detachably connected. The other end of the first filter element 41 has a second connecting plate 413, and the other end of the second filter element 42 has a fourth connecting plate 423, and the second connecting plate 413 and the fourth connecting plate 423 are detachably connected.

[0235] By extending the first connecting plate 412 and the second connecting plate 413 at both ends of the first filter element 41, and extending the third connecting plate 422 and the fourth connecting plate 423 at both ends of the second filter element 42, the first connecting plate 412 and the third connecting plate 422 are detachably connected, and the second connecting plate 413 and the fourth connecting plate 423 are detachably connected to achieve a detachable connection between the first filter element 41 and the second filter element 42.

[0236] As shown in FIG33 , the first connecting plate 412 and the third connecting plate 422 are arranged opposite to and in parallel with each other, and the second connecting plate 413 and the fourth connecting plate 423 are arranged opposite to and in parallel with each other.

[0237] In some examples, the connection between the first filter sub-element 41 and the second filter sub-element 42 is a snap connection and / or a magnetic connection, or can be plug-in connection or riveted connection.

[0238] In some examples, as shown in FIG33 , the first connecting plate 412 has at least one first through-slot 4121, and the third connecting plate 422 has at least one second protrusion 4221, with the second protrusion 4221 being adapted to be positioned one-to-one within the first through-slot 4121. The second connecting plate 413 has at least one first protrusion 4131, and the fourth connecting plate 423 has at least one second through-slot 4231, with the first protrusion 4131 being adapted to be positioned one-to-one within the second through-slot 4231. The protrusions and through-slots cooperate to achieve a snap-fit ​​connection between the first connecting plate 412 and the third connecting plate 422, and between the second connecting plate 413 and the fourth connecting plate 423.

[0239] In some examples, as shown in FIG33 , there are two first through-slots 4121, and the two first through-slots 4121 are spaced apart. Correspondingly, there are two second protrusions 4221, and the two second protrusions 4221 are spaced apart. There are two second through-slots 4231, and the two second through-slots 4231 are spaced apart. Correspondingly, there are two first protrusions 4131, and the two first protrusions 4131 are spaced apart. When the number of first through-slots 4121, second through-slots 4231, first protrusions 4131, and second protrusions 4221 is set to two, a secure connection can be ensured.

[0240] In some examples, as shown in Figures 32 and 33, the first connecting plate 412 has at least one first magnetic member 4122, and the third connecting plate 422 has at least one first groove 4222, wherein the first groove 4222 has a first metal member 4223 embedded therein. The first magnetic member 4122 is adapted to be positioned one-to-one within the first groove 4222 and to contact the first metal member 4223. The second connecting plate 413 has at least one second groove 4132, and the fourth connecting plate 423 has at least one second magnetic member 4232, wherein the second groove 4132 has a second metal member 4133 embedded therein. The second magnetic member 4232 is adapted to be positioned one-to-one within the second groove 4132 and to contact the second metal member 4133.

[0241] The magnetic connection between the first connecting plate 412 and the third connecting plate 422, as well as the magnetic connection between the second connecting plate 413 and the fourth connecting plate 423, is achieved by the use of magnetic components in conjunction with metal components. It should be noted that the connection here is a combination of magnetic components and metal components, not a combination of magnetic components. This is because when magnetic components are connected, the attraction between the two components is too strong, which can make separation difficult or damage the components.

[0242] In some examples, as shown in FIG32 , there are two first magnetic members 4122, one disposed at each end of the first connecting plate 412. Correspondingly, as shown in FIG33 , there are two first grooves 4222, one disposed at each end of the third connecting plate 422. As shown in FIG33 , there are two second magnetic members 4232, one disposed at each end of the fourth connecting plate 423. Correspondingly, as shown in FIG32 , there are two second grooves 4132, one disposed at each end of the second connecting plate 413.

[0243] It should be noted that in order to facilitate the display of the feature that the metal part is located in the groove, the metal part is removed from the groove for display in Figures 32 and 33, while in actual use, the metal part is fixed in the groove.

[0244] In some examples, as shown in Figures 32 and 33, the first magnetic member 4122 and the second magnetic member 4232 are both cylindrical structures. Of course, the first magnetic member 4122 and the second magnetic member 4232 can also be other types of structures, such as a rectangular parallelepiped, which is not specifically limited in the present embodiment.

[0245] In some examples, as shown in Figures 32 and 33, both the first metal member 4223 and the second metal member 4133 are cube-shaped. Of course, the first metal member 4223 and the second metal member 4133 can also be other types of structures, such as cylindrical, and are not specifically limited in the embodiments of the present disclosure. In some examples, the first metal member 4223 and the second metal member 4133 can both be copper sheets.

[0246] In some examples, as shown in FIG34 , the first filter element 41 has at least one first flange 414 extending away from the air inlet 11 , and / or, as shown in FIG35 , the second filter element 42 has at least one second flange 424 extending away from the air inlet 11 .

[0247] For example, referring to Figure 32 , first filter element 41 is provided with a first flange 414, and second filter element 42 is provided with a second flange 424. This arrangement allows an operator to easily separate or connect the first filter element 41 and the second filter element 42 by grasping the first flange 414 or the second flange 424. As shown in Figure 32 , both first flange 414 and second flange 424 are curved flanges, with low ends and a high center.

[0248] In some examples, as shown in Figures 34 and 35, there are two first flanges 414 and / or two second flanges 424. This arrangement further facilitates gripping by the operator.

[0249] Furthermore, as shown in FIG. 34 and FIG. 35 , two first flanges 414 are relatively arranged on both sides of a first opening 411 , and two second flanges 424 are relatively arranged on both sides of a second opening 421 .

[0250] In some examples, as shown in FIG36 , the lower side of the annular filter element 4 abuts against the housing 1 , so that the housing 1 is used to fix the lower portion of the annular filter element 4 and prevent the annular filter element 4 from loosening.

[0251] In some examples, the ceiling fan is a fan lamp. As shown in FIG36 , the housing 1 further includes a lamp assembly 1061. The first filter element 41 has an inwardly bent first bend 415, and the second filter element 42 has an inwardly bent second bend 425. Referring to FIG38 and FIG40 , the first bend 415 and the second bend 425 both abut against the step structure 10611 of the lamp assembly 1061. This arrangement allows the first and second filter elements 41 and 42 to achieve encircling abutment with the lamp assembly 1061, thereby preventing the annular filter element 4 from becoming loose on the lamp assembly 1061.

[0252] It should be noted that, in the embodiment of the present disclosure, the lamp assembly part 1061 not only realizes the assembly of the lamp module 6 , but also plays a role in fixing the annular filter 4 by abutting against the annular filter 4 .

[0253] In some examples, as shown in FIG. 31 , the housing 1 further includes a suspension assembly 5 , wherein the suspension assembly 5 abuts against the upper side of the annular filter element 4 to fix the upper portion of the annular filter element 4 .

[0254] In some examples, as shown in FIG36 , the suspension assembly 5 includes a decorative ring 55. As shown in FIG37 , the first filter element 41 has an inwardly bent first overlap portion 416, and as shown in FIG39 , the second filter element 42 has an inwardly bent second overlap portion 426. The first overlap portion 416 and the second overlap portion 426 both abut against the bottom of the decorative ring 55. This arrangement allows for a surrounding abutment between the first and second filter elements 41, 42 and the decorative ring 55.

[0255] Further, referring to Figures 37 and 39, the first overlap portion 416 has a first ridge 4161, and the second overlap portion 426 has a second ridge 4261. The first ridge 4161 and the second ridge 4261 both abut against the bottom of the decorative ring 55. That is, the first overlap portion 416 and the second overlap portion 426 utilize the first ridge 4161 and the second ridge 4261 to abut against the decorative ring 55.

[0256] In some examples, the size of the first ridge 4161 is the same as the size of the second ridge 4261 .

[0257] In some examples, the first ridge 4161 and the second ridge 4261 together form an annular ridge structure to ensure sufficient contact with the decorative ring 55 .

[0258] The ceiling fan provided in the embodiment of the present disclosure can be suspended on the installation carrier through the suspension component 5. The suspension component 5 provided in the embodiment of the present disclosure is exemplarily described below.

[0259] In some examples, as shown in Figures 41-43, the suspension assembly 5 includes a hanging cup 51, a housing 1 connected to the hanging cup 51, and an airflow chamber 10 formed within the interior of the housing 1. The motor 21 is mounted within the hanging cup 51, with the motor shaft 211 extending outside the hanging cup 51. The impeller 22 is connected to the motor shaft 211 and positioned within the airflow chamber 10. The hanging cup 51 is generally a cup-shaped structure with an open top and a closed bottom. When suspended, the top opening of the hanging cup 51 is buckled onto the ceiling. The hanging cup 51 can also be referred to as a mounting base.

[0260] In the technical solution provided in the embodiment of the present disclosure, the housing 1 is directly connected to the hanging cup 51 of the suspension assembly 5, and the hanging cup 51 can position the housing 1. The motor 21 of the fan assembly 2 is accommodated and fixed inside the hanging cup 51, and a portion of the motor shaft 211 extends from the hanging cup 51 and is directly connected to the impeller 22. Therefore, the hanging cup 51 can position the impeller 22 through the motor shaft 211, so that the relative position between the housing 1 and the impeller 22 can be determined only through the hanging cup 51 and the motor 21, making positioning easier. In addition, since the assembly dimension chain between the housing 1 and the impeller 22 is shortened, the assembly difficulty of the ceiling fan is reduced, and the assembly deviation is reduced.

[0261] In some examples, as shown in Figures 44, 45, and 46, the hanging cup 51 includes a connecting portion 512 and a receiving portion 513. The receiving portion 513 has a second receiving cavity 5133, which has an open end 5134. The motor 21 is located in the second receiving cavity 5133. The connecting portion 512 is connected to the open end 5134 of the second receiving cavity 5133 and is also connected to the housing 1.

[0262] When the ceiling fan provided by the embodiment of the present disclosure is in use, the connecting portion 512 is used to connect to the housing 1, and the accommodating portion 513 is usually located below the connecting portion 512 to accommodate the motor 21 and facilitate the connection between the motor 21 and the impeller 22.

[0263] In some examples, as shown in Figures 45 and 46, the hanging cup 51 further includes a mounting portion 511, which is located on a side of the connecting portion 512 away from the accommodating portion 513 and is used to connect the suspension assembly 5 to the mounting carrier. The mounting portion 511 is an annular structure with two open ends, having a bottom opening 5111 and a top opening 5112 that are oppositely disposed. The area of ​​the bottom opening 5111 is larger than the area of ​​the open end 5134 of the accommodating portion 513. The connecting portion 512 is used to connect the open end 5134 of the accommodating portion 513 to the bottom opening 5111 of the mounting portion 511.

[0264] As shown in Figure 45, the mounting portion 511 is an annular structure having a certain length in the axial direction of the motor shaft 211, and has a top opening 5112 and a bottom opening 5111. The top opening 5112 of the mounting portion 511 is the top opening of the hanging cup 51. The accommodating portion 513 is a cup-shaped structure, and the bottom 5131 of the accommodating portion 513 is the bottom of the hanging cup 51. The accommodating portion 513 also has an open end 5134 opposite the bottom. The connecting portion 512 is an annular structure, which is arranged between the mounting portion 511 and the accommodating portion 513. The small annular edge of the connecting portion 512 is connected to the bottom opening 5111 of the mounting portion 511, and the large annular edge is connected to the open end 5134 of the accommodating portion 513.

[0265] Generally speaking, in this embodiment, the cross-sectional area of ​​the hanging cup 51 gradually increases from the bottom 5131 toward the top opening. As shown in FIG46 , the area of ​​the opening end 5134 of the accommodating portion 513 is smaller than the area of ​​the bottom opening 5111 of the mounting portion 511. The opening end 5134 of the accommodating portion 513 is the portion with the largest cross-sectional area, while the bottom opening 5111 of the mounting portion 511 is the portion with the smallest cross-sectional area. The cross-sectional area is perpendicular to the axial direction of the motor shaft 211.

[0266] In some examples, the bottom opening 5111 of the mounting portion 511 and the open end 5134 of the accommodating portion 513 are both located on a set plane, which is perpendicular to the axial direction of the motor shaft 211. In this case, the connecting portion 512 is an annular plate, with its inner edge connected to the open end 5134 of the accommodating portion 513 and its outer edge connected to the bottom opening 5111 of the mounting portion 511. As shown in FIG44 , the gland 23 and the housing 1 are located on opposite sides of the connecting portion 512 and are both fixedly connected to the connecting portion 512.

[0267] In some examples, the housing 1 and the connecting portion 512 are connected by a first screw, and the pressure cover 23 and the connecting portion 512 are connected by a second screw.

[0268] In some examples, the third screw passes through the housing 1 , the connecting portion 512 , and the pressure cover 23 in sequence, thereby connecting the housing 1 , the hanging cup 51 , and the pressure cover 23 together.

[0269] In some examples, as shown in FIG47 , the ceiling fan further includes a control assembly 27 , which is located within the annular space enclosed by the mounting portion 511 and is connected to the mounting portion 511 . The control assembly 27 can be used to control the motor 21 . The control assembly 27 can include a control circuit board, etc., which is housed within the annular space enclosed by the mounting portion 511 and connected to the mounting portion 511 via a mounting bracket 52 .

[0270] In some examples, the mounting bracket 52 is located on a side of the control assembly 27 away from the connecting portion 512 and covers at least a portion of the top opening 5112 of the mounting portion 511 .

[0271] In some examples, the control assembly 27 is connected to the mounting bracket 52 by screws, or the control assembly 27 is clamped between the mounting bracket 52 and the pressure cover 23 .

[0272] In some examples, the mounting bracket 52 is snap-fitted to the mounting portion 511 or connected to the mounting portion 511 via screws.

[0273] It should be noted that the functions of the control component 27 are configured by technical personnel according to actual needs. For example, when the ceiling fan is a fan light, the control component 27 can also be used to control the light module 6 of the fan light.

[0274] In some examples, as shown in Figures 48 and 49 , a mounting opening 1016 is defined in the housing 1. The receiving portion 513 extends from the mounting opening 1016 into the airflow cavity 10, and the mounting portion 511 and the connecting portion 512 are both located outside the airflow cavity 10. The connecting portion 512 overlaps and is fixed to the edge of the housing 1 that encloses the mounting opening 1016.

[0275] Mounting opening 1016 is generally provided at the top of housing 1, allowing receptacle 513 of hanging cup 51 to extend through mounting opening 1016 into the inner cavity of housing 1. This reduces the distance between hanging cup 51 and impeller 22. This, on the one hand, facilitates assembly of motor shaft 211 and impeller 22, making the ceiling fan structure more compact. On the other hand, the shortened assembly distance between hanging cup 51 and impeller 22 allows hanging cup 51 to effectively position impeller 22, effectively reducing assembly errors.

[0276] The opening area of ​​the mounting opening 1016 is generally equal to or slightly larger than the area of ​​the opening end 5134 of the accommodating portion 513, but smaller than the area of ​​the bottom opening 5111 of the mounting portion 511, so that the connecting portion 512 can be overlapped on the shell 1, and there is surface contact between the connecting portion 512 and the shell 1, which fully reserves the assembly space for the screws, and when connected by screws, the connection between the connecting portion 512 and the shell 1 is more secure.

[0277] In some examples, as shown in FIG50 , the airflow chamber 10 has an air inlet 11, and an orthographic projection of the air inlet 11 along the axial direction of the motor shaft 211 at least partially overlaps with an orthographic projection of the mounting portion 511 along the axial direction of the motor shaft 211. At least a portion of the outer wall of the mounting portion 511 is configured to extend obliquely from the bottom opening 5111 toward the top opening 5112, with the outer diameter of the portion closer to the top opening 5112 increasing.

[0278] 50 , the air inlet 11 is spaced apart from the mounting opening 1016 and surrounds the mounting opening 1016. The impeller 22 is located directly below the mounting opening 1016, and the air inlet position of the impeller 22 corresponds to the position of the air inlet 11, thereby increasing the air flow rate of the ceiling fan.

[0279] However, due to the large size of the mounting portion 511 located above the air inlet 11, it blocks the air inlet opening to a certain extent, thus affecting the amount of air entering. Reducing the cross-sectional dimensions of the mounting portion 511 would affect the mounting strength between the mounting portion 511 and the mounting carrier. Therefore, in this embodiment, as shown in Figures 45 and 46, at least a portion of the outer wall of the mounting portion 511 is inclined relative to the connecting portion 512, with the inclination direction being such that the closer it is to the top opening 5112 of the mounting portion 511, the further away from the connecting portion 512 in the radial direction of the motor shaft 211. In other words, starting from the bottom opening 5111 of the mounting portion 511, at least a portion of the outer wall of the mounting portion 511 is trumpet-shaped, with the outer wall cross-sectional area at the bottom opening 5111 being the smallest. Compared to an arrangement in which the outer wall of the mounting portion 511 is perpendicular to the connecting portion 512, this embodiment significantly reduces the obstruction of the air inlet 11 by the mounting portion 511, while ensuring the mounting strength between the mounting portion 511 and the mounting carrier, thereby increasing the amount of air entering.

[0280] In some examples, as shown in FIG44 , the fan assembly 2 further includes a pressure cover 23 , which is located inside the hanging cup 51 and connected to the connecting portion 512 . The motor 21 is sandwiched between the pressure cover 23 and the bottom 5131 of the accommodating portion 513 .

[0281] In some examples, as shown in FIG. 44 , a first through hole 5132 is defined at the bottom 5131 of the accommodating portion 513 , through which the motor shaft 211 passes, and a gap is provided between the motor shaft 211 and the wall of the first through hole 5132 .

[0282] The motor 21 provided in the embodiment of the present disclosure may be an inner rotor motor, wherein the motor shaft 211 of the inner rotor motor is connected to the rotor. When the motor 21 is powered on, the motor shaft 211 can rotate around the central axis of the motor shaft 211 driven by the rotor.

[0283] The impeller 22 needs to be driven to rotate by the motor shaft 211. As shown in Figure 44, in this embodiment, the impeller 22 is located outside the hanging cup 51. In order to achieve the connection between the motor shaft 211 and the impeller 22, a first through hole 5132 can be opened at the bottom 5131 of the accommodating portion 513, so that the motor shaft 211 can extend to the outside of the hanging cup 51 through the first through hole 5132 and connect with the impeller 22, so as to facilitate the driving of the impeller 22. In particular, since the suspension component 5 and the housing 1 are both stationary during the operation of the fan assembly 2, the aperture of the first through hole 5132 needs to be larger than the diameter of the motor shaft 211, so that the motor shaft 211 passing through the first through hole 5132 does not contact the hole wall of the first through hole 5132, and the hanging cup 51 and the rotating motor shaft 211 will not interfere with each other.

[0284] In this embodiment, the motor 21 can be fixed in the hanging cup 51 by being compressed. As shown in Figure 44, the pressure cover 23 can be placed on the end of the motor 21 away from the bottom 5131 of the hanging cup 51 and is tightly connected to the hanging cup 51. The pressure cover 23 and the bottom 5131 of the hanging cup 51 cooperate to clamp the motor 21, preventing it from moving relative to the hanging cup 51, thereby achieving assembly and positioning of the motor 21 on the hanging cup 51.

[0285] In some examples, the connection between the pressure cover 23 and the hanging cup 51 can be snap-fitted, riveted, or connected via screws.

[0286] In some examples, referring to FIG. 44 , the fan assembly 2 further includes a shock absorber 24 , which is sandwiched between the motor 21 and the pressure cover 23 , and / or the shock absorber 24 is sandwiched between the motor 21 and the bottom 5131 of the accommodating portion 513 .

[0287] The shock absorbing member 24 is generally made of a soft material to prevent the motor 21 from generating noise and vibration due to rigid collision with the pressure cover 23 and the hanging cup 51 during operation.

[0288] In some examples, as shown in Figures 51 and 52 , housing 1 includes an outer shell 101 and an inner shell 102. Outer shell 101 is connected to hanging cup 51, and air inlet 11 of airflow cavity 10 is located on outer shell 101. Inner shell 102 is connected to outer shell 101 via first fasteners 103, which extend into or through shielding tongue 3.

[0289] In some examples, the first fastener 103 can be a screw, a connecting screw, etc. Taking the first fastener 103 as a screw as an example, as shown in FIG52 , the outer shell 101 and the inner shell 102 are respectively provided with screw mounting structures (e.g., screw holes), and the screws can be screwed into the screw mounting structures, thereby fixing the outer shell 101 and the inner shell 102 together.

[0290] In some examples, as shown in FIG53 , the housing 101 includes a fixing portion 1013, a housing portion 1014, and connecting ribs 1015. The housing portion 1014 is annular. The fixing portion 1013 is located inside the housing portion 1014, and the fixing portion 1013 and the housing portion 1014 are spaced apart to form an air inlet 11. At least a portion of the connecting rib 1015 is located within the air inlet 11 and connects the adjacent and opposing housing walls of the fixing portion 1013 and the housing portion 1014.

[0291] Along the radial direction of the motor shaft 211, the fixing portion 1013, the connecting rib 1015, and the cover portion 1014 are sequentially connected. The fixing portion 1013 is annular, with a mounting opening 1016 formed on its inner side. The outer side is used to cooperate with the cover portion 1014 to enclose a side edge of the air inlet 11. The fixing portion 1013 is used to be fixedly connected to the hanging cup 51. The cover portion 1014 is used to cooperate with the inner shell 102, and the shielding tongue 3 and the screw mounting structure are both connected to the cover portion 1014. The connecting rib 1015 is located between the fixing portion 1013 and the cover portion 1014, with one end connected to the fixing portion 1013 and the other end connected to the end wall 10141 of the cover portion 1014 used to enclose the air inlet 11, so that at least a portion of the connecting rib 1015 is located within the air inlet 11 and blocks a portion of the air inlet 11.

[0292] In some examples, there are multiple connecting ribs 1015, which are arranged at intervals along the circumference of the fixing portion 1013 to improve the connection strength between the fixing portion 1013 and the spacing portion. The airflow can enter the airflow cavity 10 through the gaps between adjacent connecting ribs 1015.

[0293] In some examples, each connecting rib 1015 is plate-shaped and arranged longitudinally within the air inlet 11 to increase the connection area with the fixing portion 1013 and the housing portion 1014, thereby improving the connection strength. The term "longitudinal" means that the plate surface of the plate-shaped connecting rib 1015 is perpendicular to the circumferential direction of the fixing portion 1013 and parallel to the opening direction of the air inlet 11. Therefore, airflow into the air inlet 11 is not blocked by the plate surface of the connecting rib 1015, thereby reducing the impact of the connecting rib 1015 on the air intake volume.

[0294] In some examples, as shown in FIG. 54 , the connecting rib 1015 further includes an auxiliary connecting portion 10151 connected to the outer wall 10142 of the cover portion 1014 and extending in a direction away from the fixing portion 1013 .

[0295] For the connecting rib 1015, in addition to the part located inside the air inlet 11, the connecting rib 1015 may also have an auxiliary connecting part 10151. The auxiliary connecting part 10151 is connected to a part of the connecting rib 1015 located inside the air inlet 11, so that the height of the connecting rib 1015 is higher than the outer shell 101 as a whole. That is to say, the connecting rib 1015 has a part located above the outer shell 101, wherein the height direction is along the axial direction of the motor shaft 211.

[0296] In some examples, the auxiliary connection portion 10151 of the connection rib 1015 extends radially along the motor shaft 211 and is connected to the outer wall 10142 of the housing portion 1014. The auxiliary connection portion 10151 improves the connection strength between the fixing portion 1013 and the housing portion 1014.

[0297] In some examples, the position of the extended end of the auxiliary connection part 10151 corresponds to the edge position of the impeller 22. As shown in Figures 54 and 55, the positive projection of the extended end of the auxiliary connection part 10151 along the axial direction of the motor shaft 211 is connected to the edge of the positive projection of the impeller 22 along the axial direction of the motor shaft 211.

[0298] In some examples, referring to FIG. 55 , one end of the cover portion 1014 close to the fixing portion 1013 is folded toward the inside of the airflow cavity 10 to form a first flange 10143 , and the folding portion has a smooth transition.

[0299] As shown in FIG55 , the cross-section of the first flange 10143 is generally arc-shaped, which can guide and collect the airflow from the air inlet 11 to a certain extent, making the air intake smoother. It is easy to understand that, as shown in FIG54 and FIG55 , the end wall 10141 is located on the first flange 10143.

[0300] In some examples, as shown in FIG56 , the fan assembly 2 further includes a middle piece 25 , through which the motor shaft 211 is connected to the impeller 22 . The hardness of the middle piece 25 is greater than that of the impeller 22 .

[0301] Generally speaking, the impeller 22 is made of plastic. When the impeller 22 is directly connected to the motor shaft 211, the connection between the impeller 22 and the motor shaft 211 is prone to wear during long-term operation, causing slippage between the impeller 22 and the motor shaft 211, affecting operation. By providing an intermediate piece 25 between the impeller 22 and the motor shaft 211, the wear on the impeller 22 can be reduced. Moreover, because the intermediate piece 25 is harder and more wear-resistant, it is not easily worn, thereby increasing the service life of the impeller 22. For example, the intermediate piece 25 is made of metal.

[0302] In some examples, the impeller 22 is made of plastic and is obtained by injection molding in a mold in which the intermediate piece 25 is placed. Therefore, the impeller 22 and the intermediate piece 25 are tightly connected and are not easily worn or cracked.

[0303] In some examples, as shown in FIG57 , the intermediate member 25 has a second through hole 251. The portion of the motor shaft 211 extending from the hanging cup 51 has a stopper 212. The stopper 212 has a radial dimension greater than the diameter of the second through hole 251. The motor shaft 211 passes through the second through hole 251 and is secured to the intermediate member 25 by a second fastener 26. The stopper 212 and the second fastener 26 are located on opposite sides of the intermediate member 25.

[0304] Referring to Figure 57 , the intermediate member 25 is sleeved onto the motor shaft 211, and its position is limited by the stopper 212 on the motor shaft 211. The second fastener 26 can be, for example, a nut. By providing an external thread on the motor shaft 211, the nut can be screwed onto the motor shaft 211 and positioned on the side of the intermediate member 25 away from the stopper 212. The nut then engages with the stopper 212 to clamp the intermediate member 25.

[0305] In some examples, the middle piece 25 is cylindrical, and the diameter of the middle piece 25 is larger than the radial size of the limiting portion 212 and the second fastener 26 on the motor shaft 211, so that there is surface contact between the limiting portion 212 and the middle piece 25, and between the middle piece 25 and the second fastener 26, which has better reliability and stability.

[0306] It should be noted that, in other examples, as shown in FIG. 4 , the motor 21 is disposed inside the housing 1 and connected to the inner housing 102 .

[0307] The hanging cup 51 needs to be suspended on the installation carrier through the installation bracket 52. The following is an exemplary description of the connection method between the hanging cup 51 and the installation bracket 52.

[0308] In some examples, as shown in Figures 58 and 59, the hanging cup 51 is provided with at least one first connection hole 514, which includes a circular hole 5141 and a first stopper hole 5142 that communicate with each other. A first connector 53 is connected to the mounting bracket 52 and horizontally passes through the first stopper hole 5142, abutting against the wall of the first stopper hole 5142 to restrict the vertical downward movement of the hanging cup 51. The circular hole 5141 is configured to allow the end of the first connector 53 away from the mounting bracket 52 to pass through. The mounting bracket 52 can also be referred to as a top cover.

[0309] The technical solution provided by the embodiment of the present disclosure is that the first connecting member 53 is connected to the mounting bracket 52 and passes through the first limiting hole 5142 in the first connecting hole 514 on the hanging cup 51 in the horizontal direction, and abuts against the first limiting hole 5142 to limit the vertical downward movement of the hanging cup 51, thereby realizing the suspension installation between the mounting bracket 52 and the hanging cup 51, and the circular hole 5141 allows the end of the first connecting member 53 away from the mounting bracket 52 to pass through, so that when the hanging cup 51 is assembled on the mounting bracket 52, the end of the first connecting member 53 away from the mounting bracket 52 can pass through the circular hole 5141 and move into the first limiting hole 5142 to fix the hanging cup 51, so that the hanging cup 51 can be fixedly connected to the mounting bracket 52 from the side (horizontal direction) of the hanging cup 51, thereby improving the efficiency of the suspension installation.

[0310] In some examples, as shown in Figures 58 and 59, the mounting bracket 52 has a hook 523, and the hanging cup 51 has a slot 515, and at least a portion of the hook 523 can be located within the slot 515. Furthermore, as shown in Figures 60 and 61, the first connecting hole 514 and the slot 515 are positioned so that when the first connecting member 53 abuts against the wall of the first limiting hole 5142, the hook 523 is separated from the upper sidewall of the slot 515 in the vertical direction.

[0311] In some examples, as shown in Figures 58 and 59, the free end of the hook 523 is bent upward, so that after the free end of the hook 523 passes through the slot 515 on the hanging cup 51, it can hook the slot 515 to limit the vertical downward movement of the hanging cup 51. The mating structure of the hook 523 and the slot 515 can provide additional fixing protection when the mating fixation between the first connecting member 53 and the first connecting hole 514 fails, thereby preventing the hanging cup 51 from completely separating from the mounting bracket 52 and falling. In some examples, when the first connecting member 53 abuts against the hole wall of the first limiting hole 5142, the two side walls opposite to each other in the vertical direction of the hook 523 and the slot 515 are separated, so that when the hanging cup 51 is limited in the vertical direction through the first connecting hole 514, the two side walls opposite to each other in the vertical direction of the hook 523 and the slot 515 are separated, which can avoid the suspension component 5 from making abnormal noise due to the collision between the hook 523 and the side wall of the slot 515 when in use, thereby improving the user experience.

[0312] In other embodiments, the mounting bracket 52 may have a slot, and the hanging cup 51 may have a hook. In other words, the mounting bracket 52 and the hanging cup 51 may have one and the other of the hook 523 and the slot 515, respectively.

[0313] When installing the suspension assembly 5 to the ceiling, the user can pre-fix the mounting bracket 52 to the ceiling and assemble the slot 515 on the hanging cup 51 with the hook 523 on the mounting bracket 52 to achieve pre-assembly between the mounting bracket 52 and the hanging cup 51. At this time, the hook 523 and the upper side wall of the slot 515 along the vertical direction are abutted, and the hanging cup 51 is tilted and opened relative to the mounting bracket 52, thereby facilitating wiring operations within the hanging cup 51. Subsequently, the hanging cup 51 can be raised to a horizontal position and rotated so that the first connecting member 53 moves from the circular hole 5141 to the first limiting hole 5142, thereby achieving suspension installation between the mounting bracket 52 and the hanging cup 51.

[0314] In some examples, when the hanging cup 51 is in a pre-installed state, the first connecting member 53 can be located in the circular hole 5141, so that the first connecting member 53 can be conveniently assembled into the first limiting hole 5142 after wiring is completed, and the end of the first connecting member 53 away from the mounting bracket 52 can be avoided from interfering with the inner wall of the hanging cup 51 during the installation process.

[0315] Furthermore, considering that during the process of switching the hanging cup 51 from the pre-installed state to the installed state, the hook 523 switches from abutting against the upper side wall of the slot 515 in the vertical direction to separating the hook 523 from the upper side wall of the slot 515 in the vertical direction, and when the mounting bracket 52 is already fixed to the ceiling, this means that the hanging cup 51 moves upward a certain distance in the vertical direction, thereby disengaging the hook 523 from the upper side wall of the slot 515. Furthermore, after the hanging cup 51 moves upward a certain distance, the first connecting member 53 can be aligned with the first limiting hole 5142, so that the first connecting member 53 can move from the circular hole 5141 to the first limiting hole 5142.

[0316] That is to say, in the embodiment of the present disclosure, as shown in Figure 62, the setting positions of the first connecting hole 514 and the card slot 515 also meet the following requirements: when the hook 523 abuts against the upper side wall of the card slot 515 in the vertical direction, the first connecting member 53 is located in the circular hole 5141, and in the vertical direction, the first connecting member 53 is higher than the connecting end of the first limiting hole 5142, which is the end portion where the first limiting hole 5142 is connected to the circular hole 5141.

[0317] In the disclosed embodiment, when the hanging cup 51 is installed, the hook 523 is at least vertically separated from the upper sidewall of the slot 515, while the first connector 53 abuts against the wall of the first limiting hole 5142 to secure the hanging cup 51 in its vertical position. Therefore, to ensure that the end of the first connector 53 away from the mounting bracket 52 does not interfere with the inner wall of the hanging cup 51 during installation, as shown in FIG63 , the design shape of the first connecting hole 514 must satisfy the following requirements: the distance d5 between the circular hole 5141 and the first limiting hole 5142 is no less than the distance d6 between the slot 515 and the hook 523. Distance d5 is the vertical distance between the highest point of the circular hole 5141 and the highest point of the connecting end of the first limiting hole 5142. Distance d6 is the vertical distance between the lowest point of the inner surface of the hook 523 and the upper surface of the slot 515 when the first connector 53 abuts against the wall of the first limiting hole 5142. In some examples, the locking groove 515 is a strip-shaped groove extending along the circumference of the hanging cup 51 , so that the hook 523 can slide in the locking groove 515 when the hanging cup 51 is rotated.

[0318] In some examples, the distance d5 between the circular hole 5141 and the first limiting hole 5142 is greater than the distance d6 between the slot 515 and the hook 523, so that when the hanging cup 51 is in a pre-assembled state, the hanging cup 51 and the mounting bracket 52 can be fixed only by the engagement of the slot 515 and the hook 523. In some examples, the distance d5 between the circular hole 5141 and the first limiting hole 5142 can be substantially equal to the distance d6 between the slot 515 and the hook 523, so that when the hanging cup 51 is in a pre-assembled state, the first connecting member 53 can abut against the upper side wall of the circular hole 5141 in the vertical direction, thereby achieving multi-point fixation between the hanging cup 51 and the mounting bracket 52 when the hanging cup 51 is in a pre-assembled state.

[0319] In some examples, the first connection hole 514 is a closed hole, so that the highest point of the circular hole 5141 is the highest point of the inner surface of the circular hole 5141 in the vertical direction. In some examples, the first connection hole 514 is an open hole. In this case, the highest point of the circular hole 5141 can be the highest point of the circle in which the circular hole 5141 is located in the vertical direction, and there may be no inner wall at this highest point.

[0320] In the embodiment of the present disclosure, as shown in FIG64 , the first connection hole 514 also includes a first assembly hole 5143 extending in the vertical direction. One end of the first assembly hole 5143 is connected to the circular hole 5141, and the other end of the first assembly hole 5143 passes through the end edge of the hanging cup 51 on the side close to the mounting bracket 52. By providing the first assembly hole 5143, the first connection hole 514 can be designed as an open hole. The first assembly hole 5143 provides a moving path in the vertical direction for the first connecting member 53, so that when the hanging cup 51 is lifted from the tilted state of the pre-installed state to the horizontal state, the first connecting member 53 can move into the circular hole 5141 through the open first assembly hole 5143, and then move into the first limiting hole 5142 connected to the circular hole 5141, further improving the efficiency of the suspension installation.

[0321] In some examples, as shown in Figures 58 and 64, the hanging cup 51 includes a slot 515 and two first connection holes 514. The slot 515 is located between the two first connection holes 514. By arranging the slot 515 and the first connection holes 514 at intervals, the installation stability of the hanging cup 51 is improved.

[0322] In some examples, the hanging cup 51 is a cylindrical structure having a space for accommodating electrical components, such that the horizontal cross-section of the hanging cup 51 is a circular ring, and the width of the circular ring is equal to the thickness of the sidewall of the hanging cup 51. The hanging cup 51 may include two or more first connection holes 514, and the plurality of first connection holes 514 are spaced apart along the circumference of the hanging cup 51.

[0323] In some examples, the extending length of the slot 515 along the circumferential direction of the annular ring is not less than the sum of the radius of the circular hole 5141 and the extending length of the first limiting hole 5142 along the circumferential direction of the annular ring.

[0324] In some examples, as shown in FIG65 , the suspension assembly 5 may further include at least one second connecting member 54 connected to the mounting bracket 52. The hanging cup 51 may further include at least one second connecting hole 516. One end of the second connecting hole 516 extends through the edge of the end of the hanging cup 51 near the mounting bracket 52, and the other end abuts against the second connecting member 54 to limit the vertical downward movement of the hanging cup 51. The coordination between the second connecting member 54 and the second connecting hole 516 further improves the installation stability of the hanging cup 51.

[0325] In some examples, when the hanging cup 51 is lifted from the tilted state of the pre-installed state to the horizontal state, the second connecting member 54 can be moved through the open end of the second connecting hole 516 to the other end that can limit the vertical downward movement of the hanging cup 51, so as to further improve the efficiency of the suspension installation.

[0326] In some examples, the second connection hole 516 can be separated from the first connection hole 514 to improve the installation stability of the hanging cup 51. As shown in Figure 66, the second connection hole 516 is located on the opposite side of the slot 515. Alternatively, the hanging cup 51 has a horizontal cross-section that is circular, and the second connection hole 516 and the first connection hole 514 have the same diameter.

[0327] In some examples, the hanging cup 51 includes two second connection holes 516 , wherein each second connection hole 516 may be located at the same diameter of the cross-sectional ring of the hanging cup 51 relative to one first connection hole 514 .

[0328] In the disclosed embodiment, as shown in Figures 65 and 66 , the second connection hole 516 includes a second assembly hole 5161 and a second limiting hole 5162. The second assembly hole 5161 extends vertically, with one end communicating with the second limiting hole 5162 and the other end extending through the edge of the hanging cup 51 near the mounting bracket 52. The second limiting hole 5162 extends horizontally.

[0329] In some examples, the second limiting hole 5162 extends along the circumference of the hanging cup 51 , and the extension length of the second limiting hole 5162 may be substantially equal to the extension length of the first limiting hole 5142 .

[0330] In the disclosed embodiment, as shown in Figures 58 and 64 , the first limiting hole 5142 has a horizontal extension. In some examples, the first limiting hole 5142 extends along the circumference of the hanging cup 51. The vertical width of the first limiting hole 5142 is less than the maximum dimension of the end of the first connector 53 away from the mounting bracket 52. Thus, the first limiting hole 5142 can be configured to restrict the end of the first connector 53 away from the mounting bracket 52 from passing through, thereby preventing the first connector 53 from escaping from the first limiting hole 5142.

[0331] In some examples, the first limiting hole 5142 is symmetrical about a set horizontal plane, and the set horizontal plane passes through the center of the circular hole 5141 , so that when the first connecting member 53 is concentric with the circular hole 5141 , the first connecting member 53 is aligned with the first limiting hole 5142 .

[0332] In some examples, as shown in FIG67 , the mounting bracket 52 includes a main body 521 and a second flange 522 connected to each other, with the second flange 522 extending vertically at one end away from the main body 521. One end of the first connector 53 is connected to the second flange 522, so that the first connector 53 can be integrally formed with the mounting bracket 52. Alternatively, the second flange 522 has a third connecting hole 524, and the first connector 53 extends through the third connecting hole 524.

[0333] The first connecting member 53 is any one of a screw, a bolt, and a polished rod (pin) with a head. The first connecting member 53 and the third connecting hole 524 through which it passes are both interference fit to limit the relative movement between the mounting bracket 52 and the hanging cup 51. In some examples, the second connecting member 54 is configured similarly to the first connecting member 53, that is, one end of the second connecting member 54 is connected to the second flange 522, so that the second connecting member 54 can be integrally formed with the mounting bracket 52. Alternatively, the second flange 522 has a fourth connecting hole, and the second connecting member 54 passes through the fourth connecting hole.

[0334] The embodiment of the present disclosure further provides a fan lamp, as shown in FIG3 and FIG4 , the fan lamp includes a ceiling fan and a lamp module 6 , and the lamp module 6 is connected to the housing 1 of the ceiling fan.

[0335] In some examples, as shown in FIG4 , the bottom of the inner housing 102 has a receiving groove, the lamp module 6 is circular, the lamp module 6 is disposed in the receiving groove, and the annular opening 12 surrounds the lamp module 6. In this way, when the air outlet 120 delivers air, the airflow can also dissipate heat from the lamp module 6.

[0336] The lamp module 6 can be directly placed in the receiving groove, and the inner shell 102 can be regarded as a mounting base for the lamp source. Alternatively, the lamp module 6 is an integral component and is detachably connected to the bottom of the inner shell 102.

[0337] In addition to placing the light module 6 on the bottom of the housing 1, in other examples, the light module 6 can also be placed on the side of the housing 1. Of course, the light module 6 can be placed on both the bottom and the side of the housing 1, and this is not limited in the present embodiment. The following is an exemplary description of the implementation method of placing the light module 6 on the side of the housing 1.

[0338] As shown in Figures 68, 69, and 70, the fan light also includes a lampshade 7. Lampshade 7 is connected to the housing 101 and forms a storage space. Lampshade 7 includes a top light-transmitting portion 71 and a side light-transmitting portion 72. A lamp module 6 is located within the storage space. Light emitted by lamp module 6 is emitted vertically upward through top light-transmitting portion 71 and horizontally through side light-transmitting portion 72, achieving both top and side illumination of the fan light, resulting in a good overall lighting effect.

[0339] In some examples, the horizontal cross-sectional edge of the fan light can be roughly circular, with the central axis of the fan light passing through the center of the circle. The housing 101 (including the mounting bracket 104, the air duct housing 105, and the air duct cover 106 described below), the lampshade 7, and the light shield 8 described below can be symmetrical about a plane passing through the central axis. The storage space formed between the lampshade 7 and the housing 1 can be substantially annular. The annular storage space can be connected end to end, thereby being closed in the circumferential direction of the fan light. In the vertical direction, the storage space can be closed or open.

[0340] In some examples, as shown in FIG68 , housing 101 includes a mounting frame 104 and a duct housing 105. Duct housing 105 and lampshade 7 can be connected to opposite sides of mounting frame 104, with duct housing 105 located on a side of mounting frame 104 closer to the central axis of the fan lamp. A receiving space can be formed between lampshade 7 and mounting frame 104.

[0341] In some examples, as shown in Figures 69 and 70, the lamp module 6 includes a loading plate 61 and a plurality of light-emitting elements 62. The mounting surface 611 of the loading plate 61 is connected to the housing 101, and the plurality of light-emitting elements 62 are arranged on the loading surface 612 of the loading plate 61, with the mounting surface 611 and the loading surface 612 facing each other. The top light-transmitting portion 71 and the side light-transmitting portion 72 are each at least partially located on the light-emitting side of the lamp module 6, which is the side of the loading surface 612 away from the mounting surface 611.

[0342] By arranging the top light-transmitting portion 71 and the side light-transmitting portion 72 on the light-emitting side of the lamp module 6, the light emitted by the lamp module 6 basically fills the accommodating space formed between the lampshade 7 and the outer shell 101, thereby providing sufficient light brightness for the top light-transmitting portion 71 and the side light-transmitting portion 72 in the lampshade 7.

[0343] In some examples, the lamp module 6 is an annular light strip, thereby providing uniform lighting brightness along the circumference of the lampshade 7. The mounting surface 611 and the loading surface 612 are two opposite sides along the thickness direction of the loading plate 61, and multiple light-emitting elements 62 can be arranged in an array on the loading plate 61.

[0344] In some examples, as shown in Figures 69 and 70, the loading surface 612 and the mounting surface 611 are each perpendicular to the vertical direction, and the loading surface 612 is located above the mounting surface 611. In other words, the lamp module 6 can be arranged horizontally with the light-emitting surface of the lamp module 6 facing upward. Furthermore, in the vertical direction, the loading surface 612 can be lower than the lower edge of the side light-transmitting portion 72, so that both the side light-transmitting portion 72 and the top light-transmitting portion 71 are located within the illuminated area of ​​the lamp module 6.

[0345] In some examples, as shown in FIG. 70 , the housing 101 (mounting frame 104 ) includes a flange extending in a horizontal direction, and the lamp module 6 can be fixed to the flange of the housing 101 via a loading plate 61 .

[0346] In some examples, the top light-transmitting portion 71 and the side light-transmitting portion 72 of the lampshade 7 can be separated to prevent the brightness of the light transmitted through the lampshade 7 from being too high and affecting the user experience. In some examples, as shown in Figures 69 and 70, the lampshade 7 includes a light-shielding portion 73, which is located between the top light-transmitting portion 71 and the side light-transmitting portion 72 and is configured to block the light emitted by the lamp module 6 from passing through.

[0347] In some examples, the top light-transmitting portion 71 and the side light-transmitting portion 72 may be made of a light-transmitting material to allow light to pass through, and the light-shielding portion 73 may be made of a light-shielding material to block light from passing through.

[0348] In other embodiments, as shown in Figures 69 and 70, the fan lamp also includes a light shield 8, which is connected to the lampshade 7 and is located on the side of the lampshade 7 away from the housing 101, and the light shield 8 shields the portion between the top light-transmitting portion 71 and the side light-transmitting portion 72 of the lampshade 7. The light shield 8 is configured to block the light emitted by the lamp module 6 from passing through.

[0349] In some examples, the light shield 8 can be made of a light-shielding material to prevent light from penetrating. The entire lampshade 7 can be made of a light-transmitting material. The light shield 8 shields the portion between the top light-transmitting portion 71 and the side light-transmitting portion 72 of the lampshade 7, thereby separating the top light-transmitting portion 71 and the side light-transmitting portion 72 exposed outside the fan light from each other.

[0350] In some examples, as shown in Figures 70 to 72, at least a portion of the light shield 8 abuts against the upper end of the side light-transmitting portion 72, and the side light-transmitting portion 72 is configured to limit the light shield 8 from moving downward in the vertical direction.

[0351] In some examples, as shown in Figures 71-72, the light shield 8 and the lampshade 7 respectively include one and the other of a first limiting groove 81 and a first limiting block 74, and at least a portion of the first limiting block 74 is located in the first limiting groove 81 to limit the light shield 8 from moving upward in the vertical direction.

[0352] In some examples, the side light-transmitting portion 72 may protrude outward relative to the area between it and the top light-transmitting portion 71, so that the lower end of the light shield 8 can abut against the upper end of the side light-transmitting portion 72 to limit the downward vertical movement of the light shield 8. In addition, the light shield 8 and the lampshade 7 also cooperate with the first limiting block 74 and the first limiting groove 81 to limit the upward vertical movement of the light shield 8. Therefore, the vertical movement of the light shield 8 is restricted, and the light shield 8 can be fixed relative to the lampshade 7.

[0353] In some examples, the matching structure of the first limiting groove 81 and the first limiting block 74 can also limit the downward movement of the light shield 8 in the vertical direction.

[0354] In some examples, as shown in Figures 71 and 72 , the light shield 8 includes a first retaining groove 81, and the lampshade 7 includes a first retaining block 74. The opening of the first retaining groove 81 faces the lampshade 7, and the vertical opening of the first retaining groove 81 increases as it approaches the central axis of the fan light. Therefore, by configuring the first retaining groove 81 to have a larger opening as it approaches the lampshade 7, the first retaining block 74 can be easily assembled into the first retaining groove 81 through the larger opening when assembling the light shield 8.

[0355] In some examples, as shown in Figures 71 and 72, the bottom wall of the first limiting groove 81 in the vertical direction extends in the horizontal direction, and the top wall of the first limiting groove 81 in the vertical direction is inclined to be farther away from the bottom wall as it is closer to the central axis of the fan light.

[0356] In other embodiments, the first limiting groove 81 is configured to be triangular, and correspondingly, the end of the first limiting block 74 facing the light shield 8 may also be triangular in shape. After the first limiting block 74 is inserted into the first limiting groove 81, the lower end of the first limiting block 74 can overlap the horizontally extending bottom wall. Therefore, by configuring the lower bottom wall of the first limiting groove 81 to extend horizontally, it is difficult for the light shield 8 to move vertically along the overlapping portion thereof with the lampshade 7, thereby effectively limiting the upward movement of the light shield 8.

[0357] In some examples, the first limiting groove 81 can be set on the inner wall of the light shield 8 and does not pass through the light shield 8 to ensure the integrity of the appearance of the light shield 8.

[0358] In some examples, as shown in Figures 75 and 76, the first limiting groove 81 is closed at both ends along the circumference of the light shield 8, so that the matching structure of the first limiting groove 81 and the first limiting block 74 can also be used to limit the rotation of the light shield 8 relative to the lampshade 7.

[0359] In other embodiments, the light shield 8 includes a first limiting block and the lampshade 7 includes a first limiting groove. In this case, the vertical top wall of the first limiting groove 81 on the lampshade 7 may extend horizontally to limit the upward vertical movement of the light shield 8 after the first limiting block is inserted into the first limiting groove.

[0360] When installing the light shield 8 onto the lampshade 7, to facilitate locating the mating position of the first limiting groove 81 and the first limiting block 74, in some examples, as shown in Figures 73-76 , the light shield 8 and the lampshade 7 further include one or the other of a second limiting groove 82 and a second limiting block 75, respectively. At least a portion of the second limiting block 75 is located within the first limiting groove 81 to limit rotation of the light shield 8 relative to the lampshade 7 about the central axis of the fan lamp. Furthermore, the second limiting groove 82 or the second limiting block 75 on the light shield 8 is exposed outside the light shield 8. Therefore, by providing a positioning structure (the second limiting groove 82 or the second limiting block 75) exposed on the light shield 8, it is easier to locate the assembly position of the light shield 8 when the first limiting groove or the first limiting block on the light shield 8 is not visible.

[0361] In the disclosed embodiment, as shown in Figures 73-76, the light shield 8 includes a second limiting groove 82, and the lampshade 7 includes a second limiting block 75. The second limiting groove 82 is located at the top of the light shield 8 in the vertical direction, and the second limiting groove 82 has an opening facing upward in the vertical direction. By arranging the opening of the second limiting groove 82 at the top of the light shield 8, the light shield 8 is better concealed. When the light shield 8 is installed on the lampshade 7, the second limiting groove 82 is invisible to the user, which helps to ensure the integrity of the appearance of the light shield 8. In other embodiments, the light shield 8 may include a second limiting block, and the lampshade 7 may include a second limiting groove.

[0362] In some examples, as shown in Figures 75 and 76, the second limiting grooves 82 are arranged in pairs along the circumference of the light shield 8, and the light shield 8 also includes a pair of limiting blocks 83, which are respectively located on opposite sides of the second limiting grooves 82 arranged in pairs, and one end of the limiting block 83 is connected to the side wall of the second limiting groove 82, and the other end extends downward in the vertical direction.

[0363] As shown in FIG76 , a pair of stoppers 83 spaced apart along the circumference of the light shield 8 can restrict clockwise or counterclockwise rotation of the light shield 8. Furthermore, the stoppers 83 extending vertically downward expand the vertical limiting range of the second limiting groove 82. Even if the second limit block 75 escapes from the second limiting groove 82, the stoppers 83 can still prevent the light shield 8 from rotating.

[0364] In some examples, as shown in FIG76 , the first limiting groove 81 and the second limiting groove 82 on the light shield 8 can be arranged in close proximity. For example, in the circumferential direction of the light shield 8, the first limiting groove 81 can be arranged between the two second limiting grooves 82 arranged in a pair, and in the vertical direction, the first limiting groove 81 can be located below the second limiting groove 82. Correspondingly, the first limiting block 74 and the second limiting block 75 on the lampshade 7 can be arranged in close proximity. In some examples, as shown in FIG77 and FIG78 , in the circumferential direction of the lampshade 7, the first limiting block 74 can be arranged between the two second limiting blocks 75 arranged in a pair, and in the vertical direction, the first limiting block 74 can be located below the second limiting block 75.

[0365] In some examples, as shown in Figures 84 and 85 , the air duct housing 105 further includes a support portion 1053, which abuts against at least a portion of the lampshade 7 and is configured to limit the vertical downward movement of the lampshade 7. In some examples, the support portion 1053 is disposed on the air duct housing 105. In some examples, as shown in Figure 85 , the support portion 1053 is located below the lampshade 7 and abuts against the lower end of the lampshade 7, thereby limiting the vertical downward movement of the lampshade 7. The lower end of the lampshade 7 may be located below the side light-transmitting portion 72.

[0366] In some examples, as shown in Figures 77 and 79-81, the housing 101 and the lampshade 7 respectively include one and the other of a third limiting groove 1041 and a third limiting block 76, and at least a portion of the third limiting block 76 is located in the third limiting groove 1041 to limit the lampshade 7 from moving upward in the vertical direction.

[0367] In some examples, the third limiting groove 1041 or the third limiting block 76 is provided on the mounting frame 104 in the housing 1. In some examples, as shown in Figures 79, 81, and 83, the housing 101 (mounting frame 104) includes the third limiting groove 1041, and the lampshade 7 includes the third limiting block 76. The third limiting groove 1041 penetrates the housing 101 (mounting frame 104) along the thickness direction of the housing 1 (mounting frame 104), and the top end of the third limiting groove 1041 is closed in the vertical direction, so that after the third limiting block 76 extends into the third limiting groove 1041, it can limit the upward movement of the lampshade 7 in the vertical direction by abutting against the top end of the third limiting groove 1041.

[0368] In some examples, as shown in Figures 79 and 81, the third limit block 76 on the lampshade 7 protrudes toward the housing 101 (mounting frame 104), and the third limit block 76 is set to a cantilever structure, so that when the lampshade 7 is installed on the housing 101 (mounting frame 104), the third limit block 76 can be pressed and deformed against the outer wall of the housing 101 (mounting frame 104) and then snapped into the third limit groove 1041 to improve the stability of the snap connection between the housing 101 (mounting frame 104) and the lampshade 7.

[0369] In the disclosed embodiment, as shown in Figures 80-83, the housing 101 further comprises a guide slot 1042, which is located above the third limiting slot 1041. The guide slot 1042 has an opening toward the lampshade 7 and extends vertically through the top wall of the housing 101. The guide slot 1042 is inclined toward the bottom wall of the lampshade 7, with the closer it approaches the third limiting slot 1041, the further it tilts away from the central axis of the fan lamp.

[0370] In some examples, the third limiting groove 1041 and the guide groove 1042 may both be provided on the mounting bracket 104 in the housing 101 .

[0371] In some examples, the guide groove 1042 is formed by a recessed outer surface of the housing 101 (mounting frame 104). When the lampshade 7 is mounted on the housing 101 (mounting frame 104), the third stopper 76 on the lampshade 7 enters the guide groove 1042 through the vertical opening of the guide groove 1042 and slides downward along the bottom wall of the guide groove 1042. Because the bottom wall is inclined so that the closer it approaches the third stopper 1041, the further away from the central axis of the fan light, the third stopper 76 is continuously pressed and deformed as it slides downward along the bottom wall. After the third stopper 76 slides into the third stopper 1041, the deformation is released, and the third stopper 76 can be firmly engaged in the third stopper 1041.

[0372] In other embodiments, the housing 101 includes a third limiting block, and correspondingly, the lampshade 7 includes a third limiting groove.

[0373] In some examples, as shown in FIG. 84 and FIG. 85 , the air duct housing 105 includes a first side wall 1051 located on a side of the mounting bracket 104 away from the lampshade 7 , and the mounting bracket 104 is connected to the first side wall 1051 .

[0374] In some examples, the air duct housing 105 may be an upper housing constituting the air duct, which is disposed above the fan assembly 2. An air inlet 11 may be disposed on the top of the air duct housing 105 so that the fan assembly 2 can obtain airflow from the surrounding environment through the air inlet 11. Opposite sides of a first sidewall 1051 in the air duct housing 105 may be connected to the mounting bracket 104 and the fan assembly 2, respectively.

[0375] In some examples, as shown in Figures 84, 85, 87, and 88, the air duct housing 105 further includes a second sidewall 1052, a position-limiting sub-portion 10531, and an abutting sub-portion 10532. The second sidewall 1052 is located on the side of the mounting frame 104 away from the first sidewall 1051. One end of the position-limiting sub-portion 10531 is connected to the first sidewall 1051, and the other end is connected to the abutting sub-portion 10532. The abutting sub-portion 10532 is connected between the position-limiting sub-portion 10531 and the second sidewall 1052. The position-limiting sub-portion 10531, the abutting sub-portion 10532, and the second sidewall 1052 form a position-limiting groove. The lower end of the lampshade 7 is accommodated in the position-limiting groove, and the lower end of the lampshade 7 abuts against the abutting sub-portion 10532. In some examples, the support portion 1053 includes the limiting sub-portion 10531 and the abutting sub-portion 10532 as described above.

[0376] In other words, as shown in Figures 86 and 87, the first sidewall 1051 and the second sidewall 1052 of the air duct housing 105 can be arranged sequentially in a direction away from the central axis of the fan lamp, and the support portion 1053 can be connected between the first sidewall 1051 and the second sidewall 1052. The abutting sub-portion 10532 of the support portion 1053 on the side closer to the second sidewall 1052 can be lower than the limiting sub-portion 10531 on the side closer to the first sidewall 1051 and lower than the second sidewall 1052. Thus, the abutting sub-portion 10532 is recessed downward relative to the second sidewall 1052 and the limiting sub-portion 10531 to form a limiting groove. The lower end of the lampshade 7 can be received in the limiting groove, thereby being limited between the limiting sub-portion 10531 and the second sidewall 1052.

[0377] In some examples, the lower ends of the first side wall 1051 and the second side wall 1052 can be connected together, so that after the fan lamp is assembled, the user can avoid seeing the protruding edge of the protruding air duct housing 105. In addition, by accommodating the lower end of the lampshade 7 in the limiting groove and connecting the lower ends of the first side wall 1051 and the second side wall 1052 together, the lower end of the lampshade 7 can be shielded, preventing the light of the lamp module 6 from penetrating downward in the vertical direction.

[0378] In some examples, in order to facilitate the assembly of the lower end portion of the lampshade 7 into the limiting groove, as shown in Figure 87, the limiting sub-portion 10531 includes a guide surface 105311, which is located on the side of the limiting sub-portion 10531 close to the abutting sub-portion 10532 and is located above the abutting sub-portion 10532, and the guide surface 105311 is inclined so that the closer it is to the abutting sub-portion 10532, the more it is inclined toward the direction away from the central axis of the fan lamp.

[0379] By configuring the guide surface 105311 to be inclined so as to be further away from the central axis of the fan light as it approaches the abutment sub-portion 10532, the vertical opening of the retaining groove can be formed into a bell-mouth shape, so that the size of the opening in the radial direction of the air duct housing 105 gradually increases upward in the vertical direction. Therefore, when the lampshade 7 is assembled into the retaining groove of the air duct housing 105, the lower end of the lampshade 7 can be easily aligned with the opening of the retaining groove and can slide along the guide surface 105311 into the retaining groove, thereby abutting the abutment sub-portion 10532.

[0380] In some examples, as shown in Figures 83 and 88, the mounting frame 104 further includes a wire threading opening 1043, which is configured to allow the wiring of the lamp module 6 to pass through and extend into the side of the mounting frame 104 away from the lampshade 7. In some examples, the lamp module 6 can be fixed to the flange of the mounting frame 104 that is bent away from the central axis of the fan light. The wire threading opening 1043 can penetrate the mounting frame 104 along the thickness direction of the mounting frame 104, so that the wiring of the lamp module 6 can pass through the wire threading opening 1043 and enter between the mounting frame 104 and the air duct housing 105, thereby hiding the wiring of the lamp module 6 inside the mounting frame 104 and not being visible to the user.

[0381] In some examples, the wiring of the light module 6 can pass through between the mounting frame 104 and the air duct housing 105. As shown in Figures 88-90, at least one of the mounting frame 104 and the air duct housing 105 has a wire outlet 1054, which is configured to allow the wiring of the light module 6 to pass through and pass through between the mounting frame 104 and the air duct housing 105.

[0382] In some examples, a wire outlet 1054 may be provided on the duct housing 105. A pair of spaced-apart blocks are provided on the outer wall of the duct housing 105. The gap between the blockers serves as the wire outlet 1054 to prevent the wiring from moving horizontally. In some examples, as shown in Figures 82 and 90, the mounting frame 104 may have a mating groove 1044. The pair of blocks forming the wire outlet 1054 may be at least partially located within the mating groove 1044, and a portion of the mounting frame 104 housing may cover the pair of blocks to prevent the wiring from moving vertically.

[0383] In some examples, as shown in Figures 88, 90, and 91, the air duct housing 105 further includes a wiring groove 1055. The wiring groove 1055 is located on the side of the outlet 1054 close to the central axis of the fan lamp, and the wiring groove 1055 is configured to reduce the height of the outer wall of the air duct housing 105. In some examples, the wiring groove 1055 can be formed by a depression in the outer wall of the air duct housing 105, so that when the wiring of the light module 6 passes through the wiring groove 1055, the wiring can be substantially flush with the surrounding outer wall of the air duct housing 105.

[0384] In some examples, as shown in FIG. 88 and FIG. 91 , the air duct housing 105 further includes a line-clamping portion 1056 , which is configured to route the light module 6 .

[0385] In some examples, the wire outlet 1054, the wiring groove 1055 and the wire clamping portion 1056 on the air duct housing 105 are arranged in sequence along the direction close to the central axis of the fan light, so that the wiring of the lamp module 6 enters between the mounting frame 104 and the air duct housing 105 through the wire threading opening 1043 on the mounting frame 104, and then can pass through the wire outlet 1054, and then pass through the wiring groove 1055, enter the wire clamping portion 1056 and be gathered, and then connected to the controller installed near the center of the fan light.

[0386] In some examples, as shown in FIG. 68 , FIG. 92 , and FIG. 93 , the fan light further includes an air duct cover 106 , and the wiring groove 1055 is located at a position where the distance between the air duct cover 106 and the air duct housing 105 is the smallest.

[0387] In some examples, the duct cover 106 covers the duct housing 105, and the duct cover 106 can be provided with multiple grilles around the central axis of the fan light to provide air intake and filtration. By arranging the wiring groove 1055 formed by the recessed outer wall of the housing at the position where the distance between the duct cover 106 and the duct housing 105 is the smallest, the distance between the wiring area on the duct housing 105 and the duct cover 106 can be effectively increased, thereby preventing the wiring from protruding too much from the duct housing 105 and affecting the installation of the duct cover 106.

[0388] In some examples, the location where the distance between the duct cover 106 and the duct housing 105 is smallest can be a corner of the duct housing 105. The sidewall at this corner, which is away from the central axis of the fan light, can extend substantially vertically, while the sidewall at this corner, which is closer to the central axis of the fan light, can extend substantially horizontally. Thus, by placing the wiring groove 1055 at this corner, the slope variation of the area through which the wiring passes can be reduced, preventing the wiring from bending excessively.

[0389] The above descriptions are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
