Description

Technical fields:

[0001] This utility model relates to a bladeless fan light. Background technology:

[0002] Existing bladeless fan lights generally include a lamp body, a fan wheel, and an air guide cover located outside the fan wheel. A groove is cut into the center of the light-emitting surface of the lamp body, and the fan wheel and air guide cover are embedded in the groove and protrude from it. Left and right airflow is achieved through the reciprocating rotation of the air guide cover. This design has the following drawbacks: 1. The fan wheel is exposed, and a rotatable air guide cover is required for airflow, resulting in a complex structure. 2. The light-emitting surface of the lamp body needs to have space in the groove for installing the fan wheel, which disrupts the continuity of the light-emitting surface of the lamp body. Summary of the Invention:

[0003] To overcome the problems of existing bladeless fan lights having exposed impellers and requiring rotatable air guide covers for air delivery, resulting in complex structures, this utility model provides a bladeless fan light.

[0004] A bladeless fan light includes a housing, an air duct assembly that cooperates with the housing, and a fan wheel disposed at the air inlet of the air duct assembly. The air duct assembly includes at least a first air duct, a second air duct, a third air duct, and a fourth air duct. The ends of the third air duct and the fourth air duct form a first air outlet and a second air outlet, respectively. Air enters from the air inlet under the drive of the fan wheel, flows through the first air duct, is then diverted through the second air duct, and enters the third air duct and the fourth air duct, and is finally discharged from the first air outlet and the second air outlet.

[0005] In this embodiment of the utility model, the impeller is located at the air inlet of the air duct component. Through the cooperation between the air duct component and the outer shell, the impeller is hidden inside the outer shell. At the same time, there is no need to use a rotatable air guide cover. The structure is simple. With the unique air duct design of the air duct component, multiple air ducts and multiple air outlets can be used to deliver natural air, which can bring users a good experience of enjoying natural wind from a wide angle and multiple directions.

The air duct assembly 2 includes at least a first air duct 21, a second air duct 22, a third air duct 23, and a fourth air duct 24. The ends of the third air duct 23 and the fourth air duct 24 respectively form a first air outlet 41 and a second air outlet 42. Driven by the fan wheel, air enters from the air inlet 20, flows through the first air duct 21, is then diverted through the second air duct 22, and enters the third air duct 23 and the fourth air duct 24, and is finally sent out from the first air outlet 41 and the second air outlet 42.

[0015] In this embodiment of the utility model, the impeller is located at the air inlet of the air duct component. Through the cooperation between the air duct component and the outer shell, the impeller is hidden inside the outer shell. At the same time, there is no need to use a rotatable air guide cover. The structure is simple. With the unique air duct design of the air duct component, multiple air ducts and multiple air outlets can be used to deliver natural air, which can bring users a good experience of enjoying natural wind from a wide angle and multiple directions.

[0016] Furthermore, as a preferred embodiment rather than a limitation, the widths of the first air duct 21 to the second air duct 22 gradually decrease. This simple structure facilitates the intake of as much natural air as possible.

[0017] Furthermore, as a preferred embodiment rather than a limitation, a diversion section 253 and a diversion section 263 are respectively provided between the second air duct 22 and the third air duct 23, and between the second air duct 22 and the fourth air duct 24. The second air duct 22, through the diversion section 253, transitions its width from large to small and then from small to large, thus diffusing the air once. This helps to increase the air volume and deliver as much air as possible to the third and fourth air ducts.

[0018] Furthermore, as a preferred embodiment and not a limitation of this practice, the width of the third air duct 23, from the diversion section 253 to the first air outlet 41, first gradually decreases and then increases again, thus performing secondary diffusion of the diverted air.

The left air duct shell 25 has an upper sidewall 251 extending from left to right, and the right air duct shell 26 has an upper sidewall 261 extending from right to left. The upper sidewall 251 of the left air duct shell 25 is higher than that of the right air duct shell 26, causing the upper sidewalls 251 and 261 of the left and right air duct shells to be vertically misaligned, forming an air inlet 20. The structure is simple, the air inlet design is reasonable, which is conducive to drawing in more air and enabling the air duct assembly to achieve a balanced state with the impeller.

[0025] Furthermore, as a preferred embodiment and not a limitation thereof, such as Figure 2 , Figure 3 As shown, the upper sidewall 251 of the left air duct shell, the upper sidewall 261 of the right air duct shell, and the portion on the left sidewall 252 of the left air duct shell extending from the upper sidewall 251 to the level with the upper sidewall 261 of the right air duct shell together form the first air duct 21. This simple structure facilitates the intake of more natural air.

[0026] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, such as Figure 2 , Figure 3 As shown, the portion of the left side wall 252 of the left air duct shell that is flush with the upper side wall 261 of the right air duct shell, extending to its branching section 253, and the portion of the right side wall 262 of the right air duct shell extending to its branching section 263, together form the second air duct 22. The structure is simple, and the second air duct is rationally designed. The branching sections 253 and 263 allow for primary air diffusion, which helps to increase the air volume and deliver as much air as possible to the third and fourth air ducts.

[0027] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, such as Figure 2 , Figure 3 As shown, the air duct assembly also includes a lower air duct shell 27 located below the left air duct shell 25 and the right air duct shell 26.

The structure is simple, and the third air duct, through further diffusion design, is conducive to further improving the air volume of the third air duct.

[0028] Furthermore, as a preferred embodiment and not a limitation thereof, such as Figure 2 , Figure 3As shown, the right extension 264 of the right air duct shell 26 and the upper right surface of the lower air duct shell 27 together form the fourth air duct 24.

[0032] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, such as Figure 2 , Figure 3 As shown, the upper surface of the lower air duct shell 27 is roughly arc-shaped. The structure is simple and facilitates the design of the third and fourth air ducts to transition from large to small and then from small to large simultaneously, which is beneficial for the secondary diffusion of the split airflow.

[0033] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, such as Figure 3 As shown, the left extension 254 and the right extension 264 are roughly on the same arc. The structure is simple and ensures the design of the second air duct guide structure and the primary diffusion of the air in the second air duct. At the same time, it is conducive to the design of the third and fourth air ducts to achieve the transition from large to small and then from small to large, which is conducive to the secondary diffusion of the split air.

[0035] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, such as Figure 1 As shown, the bladeless fan light is elongated in shape, and the air duct assembly is also elongated. The impeller 3 includes two impellers arranged coaxially side by side along the long side of the air duct assembly, and the two impellers are synchronously driven by the same motor.
