In this way, the direction of the air inlet and the air outlet of the bladeless fan structure are both directed to the same area, so that the air is interlaced with each other, resulting in backflow and other phenomena, and the air outlet efficiency is very low
Also, recirculation air resonance can create unpleasant audible frequency noise
Low air efficiency and high noise are the main reasons why the bladeless fan ceiling lamp cannot bring customers a better experience

Embodiment Construction
[0046] The invention discloses a ceiling lamp without a blade fan, which can improve the air outlet efficiency and reduce the noise.
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0048] like Figure 2-Figure 7 As shown, the embodiment of the present invention provides a bladeless fan ceiling lamp, comprising: an annular casing 3, an annular passage is provided inside the annular casing 3, an air inlet 31 is provided on the circumferential side wall of the annular casing, and the annular passage and the ...

The invention discloses a ceiling lamp with a blade-free fan. The ceiling lamp comprises an annular shell, an air blower which is arranged at an air inlet and a light source which is arranged on the annular shell, wherein the interior of the annular shell is provided with an annular channel; the air inlet is formed in the circumferential side wall of the annular shell; and the annular channel communicates with the air inlet; an air outlet is formed in the bottom of the shell. According to the ceiling lamp with the blade-free fan provided by the invention, through starting of the air blower, the outside air is driven to be introduced into the annular channel in the annular shell from the air inlet which is formed in the side face of the ceiling lamp with the blade-free fan, and then flows out toward the lower part of the ceiling lamp with the blade-free fan through an air outlet; and because the air outlet and the air inlet are formed in a staggered manner, the gas can get in and get out more smoothly, the backflow phenomenon is avoided, and the air-out efficiency is effectively improved; and moreover, noise caused by resonance of the backflow air is avoided, and therefore, a noisereduction effect is achieved.
Description
technical field [0001] The invention relates to the technical field of bladeless fan ceiling lamp equipment, in particular to a bladeless fan ceiling lamp. Background technique [0002] like figure 1 As shown, in the existing bladeless fan ceiling lamp, the air outlet of the bladeless fan structure is the front (downward bottom surface), and its air inlet is usually in the front or side of the middle of the lamp body. In this way, the direction of the air inlet and the air outlet of the bladeless fan structure are all directed to the same area, so that the air is interlaced with each other, and phenomena such as backflow may occur, and the air outlet efficiency is very low. Also, recirculating air resonates to produce noise at uncomfortable audible frequencies. Low air efficiency and high noise are the main reasons why the bladeless fan ceiling lamp cannot bring customers a better experience. [0003] Therefore, how to improve the air outlet efficiency and reduce the nois...
