DETAILED DESCRIPTION

[0029] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0030] As a specific embodiment, the ceiling fan device with built-in fan blades of the embodiment of the utility model includes a motor 1, a blade member 2 and an air guide cover 3; the motor 1 includes a rotating end 11 and a fixed end 12, the fixed end 12 is connected to a suspension rod 19, and the air guide cover 3 is directly or indirectly fixedly connected to the fixed end 12. Usually, the suspension rod 19 suspends the motor 1 on the top wall of the room or the like through a hanger 191 at the top thereof, so the suspension rod 19 is vertically arranged and perpendicular to the horizontal plane. The hanger cover 192 surrounds the hanger 191 to achieve dustproof, beautification and other effects.

[0031] The blade member 2 includes a blade body 22 and a blade carrier 21 fixedly connected to the rotating end 11, and the blade carrier 21 includes an inclined portion 211; the cross-section of the outer surface of the inclined portion 211 (i.e., the cross-section intercepted by the horizontal plane) is circular and the diameter gradually increases from top to bottom. For example, the outer surface of the inclined portion 211 is a truncated cone as a whole, a truncated cone with a convex or concave side, etc.

[0032] The blade body 22 includes a blade main body 221 fixedly connected to the inclined portion 211. The blade main body 221 is inclined. Figure 5 As shown, there is an angle between the blade body 221 and the horizontal plane; and the bottom end of the blade body 221 exceeds the inclined portion 211 when viewed from above, as shown in FIG. Figure 4 , 5 As shown, the bottom end of the blade body 221 is located outside the circle where the bottom end of the inclined portion 211 is located.

[0033] The air guide hood 3 includes an air inlet 31 and an annular air outlet 32 ​​whose ventilation area is smaller than that of the air inlet 31, and the air inlet 31 is completely located in the smaller circle of the annular air outlet 32 ​​when viewed from above. For example, the cross-sectional area of ​​the air inlet 31 is larger than the cross-sectional area of ​​the annular air outlet 32; it is easy to understand that when there are multiple air inlets 31, the ventilation area of ​​the annular air outlet 32 ​​is smaller than the sum of the ventilation areas of the multiple air inlets 31. It is easy to understand that the annular air outlet 32 ​​is in the shape of an annular ring. It is easy to understand that the ceiling fan blows air downward, so the air inlet 31 is located above the annular air outlet 32.

[0034] The blade member 2 is disposed in the air guide cover 3 and the bottom end of the blade body 221 faces the annular air outlet 32 ​​.

[0035] The working principle is as follows: Figure 6 As shown, the motor 1 is energized so that the rotating end 11 drives the blade body 22 of the blade member 2 to rotate, so that air enters the inner cavity of the air guide cover 3 from the air inlet 31 and then flows out from the annular air outlet 32 ​​to form blowing.

[0036] Since the blade body 221 is inclined and the bottom end of the blade body 221 exceeds the inclined portion 211 when viewed from above, the air guide cover 3 includes an air inlet 31 and an annular air outlet 32 ​​whose ventilation area is smaller than that of the air inlet 31, and the air inlet 31 is completely located within the smaller circle of the annular air outlet 32 ​​when viewed from above; when the air is pushed by the blade body 221, it has a downward flow vector and a horizontal outward (away from the fixed end 12) vector, which cooperates with the air inlet 31 and the annular air outlet 32 ​​to form a turbocharger-like effect, so that the wind pressure output from the annular air outlet 32 ​​is larger to improve comfort, and the blade member 2 is completely located in the air guide cover 3 to improve safety.

[0037] As one of the specific implementations, the air guide cover 3 includes an inner lining 33 and a chassis 34. The annular air outlet 32 ​​is arranged on the chassis 34 to form an outer wall 341 and an inner wall 342 of the air outlet. It is easy to understand that the outer wall 341 of the air outlet is located outside the annular air outlet 32, and the inner wall 342 of the air outlet is located inside the annular air outlet 32. The air inlet 31 is directly or indirectly arranged at the top of the inner lining 33, for example, the top of the inner lining 33 is directly opened to form the air inlet 31, or the inner lining 33 is fixedly connected to the outer cover 35 described later and provided with the air inlet 31, so that the top of the inner lining 33 is indirectly provided with the air inlet 31. The cross-section of the inner cavity of the liner 33 is circular and the diameter gradually increases from top to bottom. The gap (usually the gap is small) from the outer edge of the blade body 221 to the inner cavity of the liner 33 is the same. In other words, even if the selected horizontal planes are at different heights, the distance from the outer edge of the blade body 221 intercepted by the horizontal plane to the inner cavity of the liner 33 intercepted by the same horizontal plane is a gap of a fixed value. The inner cavity of the liner 33 and the inclined portion 211 enclose a space that is closed inside and outside. The blade body 221 rotates in the closed space, which can ensure that the wind pressure output from the annular air outlet 32 ​​is relatively large.

[0038] As one of the specific implementations, the air guide cover 3 also includes an outer cover 35 fixedly connected to the fixed end 12, such as by a hanging head 193, the liner 33 is fixed in the outer cover 35, such as by screws, the outer cover 35 includes a sealing portion 351, the sealing portion 351 is a portion of the outer cover 35 lower than the bottom end of the liner 33, and the sealing portion 351 is fixedly connected to the outer wall 341 of the air outlet, such as the sealing portion 351 is snugly sleeved on the outer wall 341 of the air outlet and the sealing portion 351 is fixedly connected to the outer wall 341 of the air outlet by a buckle 39. While facilitating the assembly of the air guide cover 3, it can ensure that the wind pressure output from the annular air outlet 32 ​​is relatively large.

[0039] As one of the specific implementations, the top of the outer cover 35 is a flat plate, and the air inlet 31 is arranged on the top of the outer cover 35; the top of the blade carrier 21 is a horizontal portion 212, and the top of the blade body 221 extends upward and exceeds the horizontal portion 212 to form an upper extension portion 222, such as Figure 6 As shown, the upper extension part 222 is roughly triangular, trapezoidal, etc. when viewed from the side, and its width when viewed from the side gradually increases from top to bottom. The top of the outer cover 35 and the horizontal part 212 enclose a roughly cylindrical space, and the upper extension part 222 rotates in the space. The upper extension part 222 at a higher position has a smaller pushing area for air and allows more air to flow downward from the inner side of the upper extension part 222. The upper extension part 222 at a lower position (such as a position close to the horizontal part 212) has a larger pushing area for air and pushes the air to make the air move away from the rotating end 11 more quickly, thereby increasing the air intake from the air inlet 31, and further increasing the wind pressure output by the annular air outlet 32.

[0040] As one of the specific implementations, there are multiple air inlets 31 evenly distributed around the rotating end 11 .

[0041] As one of the specific implementations, a mounting portion 213 is provided in the middle of the horizontal portion 212 ; the mounting portion 213 is fixedly connected to the rotating end 11 .

[0042] As one of the specific implementations, the bottom end of the blade carrier 21 is provided with a bottom opening 214, and the bottom plate 34 at least partially passes through the bottom opening 214 so that there is an overlap between the bottom plate 34 and the blade carrier 21 in the height direction. The overall thickness of the ceiling fan device can be reduced to save space, and this embodiment is particularly suitable for the case where the height of the room ceiling is low.

[0043] As one of the specific implementations, a bottom connecting piece 129 is fixedly provided at the lower end of the fixed end 12; the bottom connecting piece 129 is fixedly connected to the bottom chassis 34; and the bottom connecting piece 129 and the bottom chassis 34 together form a cavity with an opening facing downward.

[0044] As one of the specific implementations, it also includes an illumination device 9 with a light-emitting function, such as an LED lamp panel, etc. The illumination device 9 is fixed to the bottom end of the bottom connecting member 129, and a light-transmitting lampshade 91 surrounding the illumination device 9 is provided on the chassis 34, so as to realize lighting by utilizing the lower end surface of the air guide cover 3. It is easy to understand that the illumination device 9 is located in the cavity formed by the bottom connecting member 129 and the chassis 34.
