[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-4A bladeless fan lamp with smooth air supply comprises a fan body 1 and a lighting fixture 2 installed below the fan body 1, a duct housing 3 is installed in the fan body 1, an air inlet 4 is arranged on the top of the duct housing 3, an annular opening 5 is formed between the duct housing 3 and the lower end edge of the lighting fixture 2, a fan assembly is installed inside the duct housing 3, and a plurality of dividing parts 7 arranged in a ring shape around the fan assembly are arranged on the inner edge of the duct housing 3, the dividing part 7 divides the annular opening 5 into a plurality of air outlets 8, on the one hand, the dividing part partially blocks the annular opening Partial shielding is achieved, while the air output of the fan assembly remains unchanged, thereby increasing the wind speed of each air outlet. On the other hand, the dividing portion 7 is provided with a front boost surface 9 and a rear boost surface 10, and the front boost surface 9 is in an inwardly concave arc shape, and the concave surface faces the fan assembly, and an air outlet duct 11 is formed between the front boost surface 9 and the rear boost surface 10 of the two adjacent dividing portions 7, and the air outlet duct 11 is directly opposite to the air outlet 8, so that the wind can flow more smoothly, reducing wind resistance, improving the smoothness of the air outlet, so that the wind blown out from the air outlet can reach the target area in a more concentrated and powerful manner, thereby improving the air supply efficiency.

[0020] The fan assembly includes an impeller 6, such as Figure 4 As shown (part A is a partial cross-sectional view), A is the blade of the impeller 6. When the impeller 6 rotates, the air is shot toward the direction of the air outlet 11 to form wind. The air outlet direction of the fan assembly is an oblique direction, forming an angle less than 90° with the diameter of the fan assembly, which is generally 30°-60°. The air outlet 11 is adapted to the air outlet direction of the fan assembly to avoid the influence of the front boost surface 9 or the rear boost surface 10 on the wind as much as possible. If the direction of the wind is slightly changed, when the wind passes through the air outlet 11 and is changed in direction, it means that a collision occurs between the wind and the front boost surface 9 or the rear boost surface 10, and the kinetic energy of the wind will decrease, thereby reducing the distance and smoothness of the air supply.

[0021] The junction of the front supercharged surface 9 and the rear supercharged surface 10 on the dividing portion 7 is an arc surface, the function of which is to reduce wind noise. If it is a right angle, there will be a lot of wind noise.

[0022] Embodiment 1: The rear supercharging surface 10 is arc-shaped and symmetrical with the curvature of the front supercharging surface 9 .

[0023] Embodiment 2: The rear supercharging surface 10 is arc-shaped and has a similar curvature to that of the front supercharging surface 9 .

[0024] Embodiment 3: The rear boost surface 10 is flat.

[0025] The dividing portion 7 and the air duct housing 3 are an integral structure, or the dividing portion 7 is a separate part fixedly connected to the air duct housing 3 via a connecting piece.
