DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] A bladeless fan lamp, comprising a shell 1, a lighting lamp module and a top mounting assembly 2, the lighting lamp module comprises a lamp shell 3, lamp beads and a lampshade 4, the lamp beads are arranged in the lamp shell 3, the lamp shell 3 is arc-shaped with the opening downward, the lampshade 4 is installed at the lower end of the lamp shell 3 for covering the lamp beads, the shell 1 covers the outer side of the lamp shell 3 from the top and is fixedly connected with the lamp shell 3, the top mounting assembly 2 is arranged at the upper end of the shell 1, the bladeless fan lamp is installed on the roof through the top mounting assembly 2, and the top mounting assembly 2 comprises a mounting rack fixedly connected on the upper end of the shell, and the upper end of the mounting rack is connected with the roof through bolts.

[0026] The upper end of the shell 1 and the upper end of the lamp shell 3 are provided with a wind cavity 7, the upper end of the shell 1 is provided with an air inlet 8 in communication with the wind cavity 7, the lower end of the shell 1 is provided with a blowing port 5 in communication with the wind cavity 7, the blowing port 5 is formed in the gap between the lower end of the shell 1 and the lower end of the lamp shell 3, and the blowing port 5 is arranged around the lighting lamp module, the blowing port 5 extends upwards and converges inwards to form a ventilation channel in communication with the wind cavity 7, and the ventilation channel is arranged around the lighting lamp module and is in communication with the periphery of the wind cavity 7;

[0027] The wind cavity 7 is provided with a bladeless fan assembly, which comprises an upper cover 11, a lower cover 12, a motor 9, a wind wheel 10 and a plurality of curved blades 13. The wind wheel 10 is installed on the motor 9, the motor 9 is installed on the upper end of the lamp shell 3, the lower cover 12 is installed on the wind wheel 10, and the upper cover 11 is located above the lower cover 12. The upper cover 11 and the lower cover 12 are annular and coaxially arranged. A through hole corresponding to the air inlet 8 is formed in the center of the upper cover 11. The through hole is located in the center of the upper cover 11. The lower cover 12 is arranged around the wind wheel 10. The inner diameter of the upper cover 11 is greater than the outer diameter of the lower cover 12. The surface of the lower cover 12 is inclined downward from the inside to the outside. The lower end of the upper cover 11 is inclined corresponding to the lower cover 12. The upper cover 11 and the lower cover 12 are connected by a plurality of curved blades 13. The upper end of the curved blade is connected with the upper cover 11, and the lower end of the curved blade 13 is connected with the lower cover. The plurality of curved blades 13 are uniformly distributed around the center of the upper cover 11 and the lower cover 12. The curved blade 13 is arranged in a backward inclination. The curved blade 13 is curved and extends from the inside to the outside towards the opposite direction of the rotation of the wind wheel 10. Adjacent two curved blades 13 and the upper cover 11 and the lower cover 12 form a downward inclined wind wheel duct.

[0028] The motor 9 drives the wind wheel 10 and the curved fan wheel to rotate, thereby attracting air from the air inlet 8 into the through hole of the upper cover 11, and then rotating and accelerating at high speed through the downward inclined wind wheel 10 duct, and then rotating and throwing out at high speed from the air outlet. Generally, the wind wheel 10 rotates counterclockwise. The angle between the overall direction of the curved blade 13 and the tangent direction of the wind wheel 10 rotation is less than 90 degrees, and the curved blade 13 is arranged in a backward inclination. The overall blade area is larger. The fluid passes through the curved surface of the curved blade 13 more smoothly, so that the turbulent flow and the backflow shock are less, the air volume is larger, the silent effect is better, and the energy saving is better. More work is done under the same power.

[0029] At the same time, the wind wheel duct is inclined downward, so that the airflow rotates and accelerates at high speed through the curved blade 13, and then is thrown downward. When the airflow passes through the wind wheel duct, due to the downward inclined lower end of the upper cover 11, the airflow hits the downward inclined lower end of the upper cover 11, is compressed in the downward space, part of the kinetic energy is converted into potential energy to generate greater airflow pressure and faster airflow speed. According to the principle of jet flow, the airflow passing through the lower cover 12 is driven by the high-speed high-pressure airflow passing through the upper cover 11 to increase the flow rate and flow.

[0030] At the same time, since the outer diameter of the lower cover 12 is smaller than the inner diameter of the upper cover 11, the production process of the entire bladeless fan assembly is simpler and more energy-saving. The normal injection mold opening can be used without increasing the complex process, saving the production cost and reducing the production difficulty and the defective rate.

[0031] The upper end surface of the lamp shell 3 and the inner wall of the outer shell 1 are both gradually curved and inclined downward from the middle to the periphery, forming an inclined downward ventilation channel connected to the air outlet 5. A plurality of flow guide volutes 14 are connected between the lamp shell 3 and the outer shell 1, and the flow guide volutes 14 are arranged along the ventilation channel and inclined downward, and are arranged to be deflected toward the direction of rotation of the wind wheel 10. The plurality of flow guide volutes 14 are uniformly distributed around the wind wheel 10, and the adjacent two flow guide volutes 14 and the upper end of the lamp shell 3 and the inner wall of the outer shell 1 form an air blowing channel connected to the air blowing channel 5.

[0032] The high-speed airflow ejected from the bladeless fan assembly is guided and pressurized by the flow guide volute 14, and is quickly blown out of the air outlet 5. The wind wheel 10 rotates counterclockwise, and the airflow also rotates counterclockwise and moves downward, so the shape of the flow guide volute 14 is set to be deflected in the counterclockwise direction, and the angle of the upper end is large.

[0033] The lower end of the flow guide volute 14 is bent to form a tail 16, so that the lower end of the flow guide volute 14 is gradually curved to be concave in the opposite direction, and the wind wheel channel formed by the upper cover 11 and the lower cover 12 gradually guides the rotating airflow to be blown vertically downward.

[0034] The upper end of the flow guide volute 14 is large in size and is hollow, and a large area of the front end can effectively reduce noise. The principle is similar to the structure of an airplane wing, and the front stroke of the airflow is greater than the back stroke, which can effectively accelerate the speed of the fluid.

[0035] The upper end of the outer shell 1 and the upper end of the upper cover 11 form a bent backflow channel 15, and the outlet direction of the backflow channel 15 is inwardly arranged. The inner side of the upper end of the outer shell 1 extends to above the through hole of the upper cover 11 and bends downward, so that the end of the backflow channel 15 has a downward inclined angle. The projection of the air inlet is located in the through hole of the upper cover 11, that is, the size of the air inlet is smaller than the size of the through hole of the upper cover.

[0036] Because the airflow in the air chamber 7 is high-speed and high-pressure gas, part of the airflow will be squeezed out of the gap between the upper cover 11 and the outer shell 1, and will collide with the airflow entering the through hole at high speed from the air inlet 8, generating noise and turbulent flow, which will affect the work of the whole fan lamp. By arranging the bent backflow channel 15, the overflowing airflow is diverted along the backflow channel 15 and reflows back to the bladeless fan assembly through the through hole.
