This fan light has a reasonable structural design, is provided with a second light source, and cooperates with the annular transmissive cover and the translucent plastic blades. When the fan blades rotate, light from the second light source is transmitted outward through the fan blades, thereby enhancing the decorative effect and having strong applicability and good practicality." Technical issues

[0003] The fan lamp of the above structure has the following shortcomings: (1) The fan part adopts traditional fan blades, and its air outlet is large and set in the center of the lamp. Due to the position limitation of the central air outlet, the selected lamp cannot emit light in the center of the bottom of the fan lamp, affecting the lighting effect; (2) Since the air outlet is in the center of the bottom of the fan lamp, the blowing effect is concentrated below the bottom of the fan lamp, and the blowing effect around the fan lamp is poor; In addition, the large air outlet at the bottom of the fan lamp is easy to be dusty, and when the fan blades are dusty, the dust is easily blown out directly from the air outlet, affecting user use. Technical Solutions

[0004] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and to provide a fan lamp which has good lighting effect, is not easy to get dusty, has a large blowing angle and good blowing effect.

[0005] The object of the present invention is achieved like this:

[0009] Specifically, partitions are respectively provided on the inner annular air duct and the outer annular air duct, which separate the inner annular air duct and the outer annular air duct into multiple independent air outlets. The multiple independent air outlets can cooperate with the air outlet of each fan blade on the wind wheel to improve the blowing effect.

[0010] Specifically, the air outlet is arc-shaped, and the air outlet on the inner annular air duct is located between two corresponding air outlets on the outer annular air duct. This herringbone layout between the three adjacent air outlets makes the air supply more uniform.

[0011] Specifically, the shell includes a chassis and an upper shell, the top of the upper shell is provided with an air inlet, the upper shell is fixed to the upper part of the chassis, and the wind wheel and the motor are placed between the chassis and the upper shell.

[0012] Specifically, the wind wheel includes a top plate, a motor base and fan blades. The top plate is provided with an air inlet. The fan blades are connected between the motor base and the top plate, and the motor base is located below the air inlet. The motor base is provided with a motor cavity with an open bottom and a top connected to the air inlet. The motor is fixed in the motor cavity. A main shaft is provided on the motor, and the main shaft extends upward out of the air inlet. One end of the fan blade is connected to the outer side wall of the motor base, and the other end extends to the outer edge of the bottom wall of the top plate. This wind wheel structure is simple and is conducive to coordination and fixation with the motor.

[0013] Specifically, the fan blades are thin sheets and extend in an arc shape, the top plate is in a circular ring shape, and multiple fan blades are evenly connected to the outer wall of the motor base, and the upper edges of the outer ends of the fan blades are connected to the bottom wall of the top plate; this type of thin sheet fan blades surrounds the motor base and is combined with multiple air outlets to provide a better blowing effect.

[0014] Specifically, a plurality of limiting protrusions are evenly arranged on the inner side wall of the motor cavity, and the motor abuts against the limiting protrusions, which is conducive to better fixing of the motor.

[0015] Specifically, an annular extension surface is provided around the bottom open opening of the motor cavity, and the vertical projection of the annular extension surface is located within the vertical projection of the air inlet. The lower edge of one end of the fan blade connected to the outer wall of the motor base is connected to the top wall of the annular extension surface. This design in which the air inlet is larger than the annular extension surface is conducive to increasing the axial air intake and enhancing the blowing effect.

[0016] Specifically, it also includes a hanging pipe, the lower end of the main shaft of the motor passes through the chassis, and the upper end thereof is connected to the lower part of the hanging pipe, and the lower part of the hanging pipe is also fixed with an air inlet mesh cover, which is located above the air inlet of the upper shell; the air inlet mesh cover is fixed on the hanging pipe, which is conducive to the installation and disassembly of the air inlet mesh cover, and because the height of the air inlet mesh cover can be adjusted, the air intake volume can be adjusted to meet the user's blowing effect requirements. Beneficial effects

[0017] (1) The fan lamp uses a wind wheel instead of traditional fan blades, and is equipped with at least two air outlets with different inclination angles, and the air outlets are arranged at the lower part of the shell of the lamp periphery. Since the number of air outlets is increased and the inclination angles of the air outlets are different, the air outlet angle is significantly increased, and the blowing effect is improved; in addition, since the air outlets are on the periphery of the lamp, the lamp is not restricted by the air outlets, and the area of ​​the lamp can be increased, the lighting area can be increased, and the lighting effect can be improved; what is more, the lamp covers the wind wheel, avoiding the disadvantage that the wind wheel is exposed over a large area and easily stained with dust.

[0018] (2) This annular air outlet design is conducive to coordinating the axial air inlet and radial air supply modes of the wind wheel, thereby improving the air supply effect. Moreover, the design of the inner and outer annular air outlets has different inclination angles. The inclination angle of the outer air outlet is greater than that of the inner air outlet. This can take into account the air supply to the downward and surrounding areas at the same time, significantly increasing the air supply area.

[0019] (3) The air inlet grille is fixed on the hanging pipe, which is convenient for installation and disassembly of the air inlet grille. In addition, the height of the air inlet grille can be adjusted, thereby adjusting the air intake volume to meet the user's requirements for blowing effect. BRIEF DESCRIPTION OF THE DRAWINGS
