Description

Technical Field

[0001] The utility model relates to a bladeless fan lamp. Background Art

[0002] Currently, fan lamps on the market feature retractable blades. These blades extend due to centrifugal force during rotation and retract into the lamp housing after the lamp stops, effectively concealing the blades. These fan lamps have complex blade expansion and contraction mechanisms, a large number of parts, and complex assembly processes, resulting in high production costs. Utility Model Content

[0003] The purpose of the utility model is to provide an improved bladeless fan lamp which reduces the number of parts and lowers the production cost.

[0004] The purpose of this utility model is achieved like this.

[0005] An improved bladeless fan lamp includes a fan body and a lamp. The fan body includes an outer rotor motor, a shell and a wind wheel. The outer rotor motor drives the wind wheel to rotate in the shell. The shell includes an upper shell and a lower shell. A fixing hole is provided at the center of the bottom of the lower shell. The fixed shaft of the outer rotor motor passes downward through the fixing hole and is connected and fixed with a nut. The bearing fixing part of the outer rotor motor and the nut clamp the lower shell around the fixing hole. The lower shell supports the upper shell. An air duct for accommodating the wind wheel is formed between the lower shell and the upper shell. An air outlet of the air duct is provided around the lower shell. The upper shell is provided with an air inlet of the air duct. The lamp is fixed to the bottom surface of the lower shell.

[0006] Compared with the prior art, the utility model has a lower shell, a fixed shaft and a nut connected and fixed, a simpler structure, fewer assembly parts required, a simpler assembly process, lower overall production costs, and is more competitive in the market.

[0007] Furthermore, the lower shell has an abutting surrounding wall extending upward around the fixing hole, and the top of the abutting surrounding wall abuts against the bearing fixing part of the outer rotor motor.

[0008] The abutting wall has a certain height, which can easily abut against the fixed part of the bearing, while preventing the lower shell from being lifted up, resulting in insufficient clearance between the wind wheel and the lower shell, and affecting the rotation of the wind wheel.

[0009] Furthermore, a plurality of first reinforcing ribs are provided on the top surface of the lower shell and around the abutting surrounding wall.

[0010] The first reinforcing rib increases the structural strength of the lower shell and the abutting surrounding wall.

[0011] Furthermore, an annular protrusion extends upward from the top surface of the lower shell around the periphery of the abutting surrounding wall, and the inner periphery of the annular protrusion, the top surface of the lower shell and the outer periphery of the abutting surrounding wall are connected by the first reinforcing ribs.

[0012] The structural strength of the lower shell is further strengthened to support the weight of the lamp and the upper shell.

[0013] Furthermore, the air inlet is provided at the center of the upper shell, and a protective frame is provided on the fan body corresponding to the air inlet, and the protective frame is provided with a plurality of hollow parts for air to pass through.

[0014] The protective frame prevents larger foreign objects from entering the air duct.

[0015] Furthermore, the center of the protection frame is connected and fixed to the top of the fixed shaft, and the periphery of the protection frame is connected and fixed to the upper shell through a connecting piece.

[0016] The center and edges of the protection frame are fixed, so the protection frame is not easy to shake.

[0017] Furthermore, a protective cover is provided on the top of the fixed shaft corresponding to the fan body. The cross section of the protective cover is in the shape of an inverted trumpet, and the connection part of the outer rotor motor is placed within the vertical projection range of the outer contour of the protective cover.

[0018] The outer periphery of the protective cover can guide the air flow into the air inlet, and the outer periphery of the protective cover prevents foreign matter from contacting the motor, especially prevents liquid from flowing downward into the motor.

[0019] Furthermore, the annular protrusion is hollow with an open bottom surface, and a second reinforcing rib extends radially along the lower shell inside the annular protrusion.

[0020] The second reinforcement rib increases the structural strength of the lower shell.

[0021] Compared with existing technologies, this utility model features a simpler structure, fewer parts, a simpler assembly process, and lower overall production costs, making it more competitive in the market. The lower housing is also structurally stronger and less susceptible to damage. The protective frame is secured at both the center and edges, making it less susceptible to shaking. The protective cover protects the motor from damage, malfunction, or even failure. BRIEF DESCRIPTION OF THE DRAWINGS

The housing 11 includes an upper housing 4 and a lower housing 3. A fixing hole 30 is provided at the bottom center of the lower housing 3. An abutting wall 31 extends upward from the lower housing 3 around the fixing hole 30. An annular protrusion 32 extends upward from the top surface of the lower housing 3 around the abutting wall 31. The inner periphery of the annular protrusion 32, the top surface of the lower housing 3 and the outer periphery of the abutting wall 31 are connected by a plurality of first reinforcing ribs 33. The first reinforcing ribs 33 are arranged at equal intervals in a circular pattern. An air outlet 52 is provided around the periphery of the lower housing 3. The annular protrusion 32 is hollow with an open bottom surface. A second reinforcing rib 34 extends radially from the inside of the annular protrusion 32 along the lower housing 3.

[0030] An air inlet 51 is centrally located in the upper housing 4. The protective frame 15 and protective cover 16 are both secured to the top of the outer rotor motor 12's fixed shaft 10. The outer rotor motor 12's fixed shaft 10 extends downward through the fixing hole 30 and is secured to the nut 7. The outer rotor motor 12's bearing 6 securing portion and the nut 7 clamp the lower housing 3 around the fixing hole 30, abutting the top of the surrounding wall 31 against the outer rotor motor 12's bearing 6 securing portion.

[0031] The lower shell 3 supports the upper shell 4 , and an air duct 5 for accommodating the wind wheel 13 is formed between the lower shell 3 and the upper shell 4 . The air inlet 51 and the air outlet 52 are connected to the air duct 5 .

[0032] The center of the protective frame 15 is fixedly connected to the top of the fixed shaft 10. The perimeter of the protective frame 15 is connected to the upper shell 4 via connectors (such as screws, not shown). The protective frame 15 is positioned at the air inlet 51 and has several hollowed-out areas for airflow. Airflow enters the air inlet 51 through these hollowed-out areas.

[0033] A protective cover 16 is fixed to the top of the fixed shaft 10 above the protective frame 15. The cross-section of the protective cover 16 is inverted trumpet-shaped, and the connection point of the outer rotor motor 12 is located within the vertical projection of the outer contour of the protective cover 16. In this embodiment, the top of the protective cover 16 is open and the bottom is closed. The outer curved surface of the protective cover 16 guides airflow into the air inlet 51. The top of the protective cover 16 is detachably connected (e.g., with a screw-on connection and / or screws) to a ceiling cup 14. The fan body 1 is secured to the ceiling or suspended ceiling via the ceiling cup 14 and the protective cover 16.

[0034] The lamp 2 is fixed to the bottom of the lower shell 3. The lamp 2 includes an LED light strip 21 and a lampshade 22. The LED light strip 21 is fixed to the bottom of the lower shell 3, and the lampshade 22 is fixed to the bottom of the lower shell 3 by a buckle. The air outlet 52 is located on the bottom of the lower shell 3 and outside the lampshade 22.

[0035] The outer rotor motor 12 drives the wind wheel 13 to rotate in the housing 11 , blowing the air in the air duct 5 out from the air outlet 52 and sucking the air in from the air inlet 51 at the same time.
