[0044] The fan body 100 is provided with an air duct 200, and an air inlet 112 and an air outlet 300 connected with the air duct 200, the air outlet 300 is arranged downward, a noise reduction pattern area is arranged in the air duct 200, and the noise reduction pattern area is located in the entire air duct 200, or in a part of the air duct 200, and a driving member 610 is arranged on the fan body 100, and the driving member 610 is connected to a fan blade member 620 located in the air duct 200, and the driving member 610 can drive the fan blade member 620 to rotate to drive the air flow in the air duct 200. Among them, the driving member 610 is set as a motor.

[0045] Through the above structure, a noise reduction pattern area is provided in the air duct 200, and the noise reduction pattern area is located in the entire air duct 200, or in part of the air duct 200. When the bladeless fan device is in working state, the noise sound waves generated in the air duct 200 will be transmitted to the noise reduction pattern area. Under the action of the noise reduction pattern area, the noise sound waves will be reflected and scattered multiple times, wherein the noise sound waves that have been reflected and scattered multiple times interfere with each other, and the energy of the noise sound waves is dispersed and consumed. Therefore, the noise is reduced to optimize the user experience.

[0046] The fan body 100 includes a ceiling cup 110 , an outer shell 120 and an inner shell 130 .

[0047] Reference Figure 2 and Figure 3 The ceiling cup 110 is provided with a first cavity 111 and an air inlet 112 connected to the first cavity 111. The outer shell 120 is provided on the lower side of the ceiling cup 110. The outer shell 120 is provided with a second cavity 121. The second cavity 121 has an opening arranged downward. The inner shell 130 is provided in the second cavity 121 to separate the second cavity 121 into a third cavity 121A and a fourth cavity 121B arranged inside and outside. The side wall of the opening and the inner shell 130 are spaced apart to form an air outlet 300 connected to the fourth cavity 121B. The fourth cavity 121B is connected to the first cavity 111 to form an air duct 200. The cavity wall of the fourth cavity 121B is provided with a noise reduction pattern area. The driving member 610 is provided on the inner shell 130, and the fan blade member 620 is located in the fourth cavity 121B.

[0048] In some embodiments, the cavity wall of the first cavity 111 is also provided with a noise reduction pattern area.

[0049] The wall of the fourth cavity 121B is provided with a noise reduction pattern area. For details, refer to Figures 2 to 4 The shell wall of the outer shell member 120 and the shell wall of the inner shell member 130 are both provided with a noise reduction pattern area located in the fourth cavity 121B.

[0050] In some embodiments, one of the shell wall of the outer shell 120 and the shell wall of the inner shell 130 is provided with a noise reduction pattern area located in the fourth cavity 121B.

[0051] In this embodiment, refer to Figure 2 and Figure 3 The shell 120 is provided with a through hole 122, the first cavity 111 is connected with the fourth cavity 121B through the through hole 122, the shell 120 is provided with a sound insulation ring cover 500 located in the fourth cavity 121B, the sound insulation ring cover 500 is passed through the through hole 122, and the side wall of the sound insulation ring cover 500 is also provided with a noise reduction pattern area.

[0052] Through the above structure, the sound waves of the noise generated in the air duct 200 will also be transmitted to the noise reduction pattern area on the side wall of the sound insulation ring cover 500. Therefore, the noise sound waves will be reflected and scattered more times. Among them, the degree of mutual interference between the noise sound waves that have been reflected and scattered more times increases, and the degree of energy dispersion consumption of the noise sound waves also increases. Therefore, the noise can be further reduced, so as to further optimize the user experience.

[0053] In this embodiment, refer to Figure 5 The noise reduction pattern area includes a plurality of noise reduction bumps 400 , and the thickness of the noise reduction bumps 400 is H, wherein 3um≤H≤1.5mm.

[0054] It should be noted that if the thickness of the noise reduction bump 400 is large, the noise reduction bump 400 becomes a bump that blocks air, which will affect the flow of air in the air duct 200, and further affect the air outlet efficiency of the bladeless fan device; if the thickness of the noise reduction bump 400 is small, the ability of the noise reduction bump 400 to reflect and scatter noise sound waves is weak, that is, the noise reduction effect of the noise reduction pattern area is poor. In summary, after many tests by the inventor, 3um≤H≤1.5mm is the optimal thickness range.

[0055] It can be understood that the plurality of noise reduction bumps 400 are at least three noise reduction bumps 400 .

[0056] In this embodiment, refer to Figure 5 The noise reduction protrusion 400 has an L-shaped structure, and a plurality of noise reduction protrusions 400 are arranged in pairs, and one end of one of the two corresponding noise reduction protrusions 400 is arranged at the corner of the other, and one end of the other is arranged at the corner of one.

[0057] Through the above structure, one end of one of the two corresponding noise reduction protrusions 400 is arranged at the corner of the other one, and one end of the other one is arranged at the corner of one of them. Therefore, the pattern of the overall noise reduction area can be made into a maze pattern structure, so as to increase the number of reflections and scattering of noise waves, thereby further reducing noise and optimizing the user experience.

[0058] In some embodiments, reference Figure 6 , the noise reduction protrusion 400 has a triangular structure.

[0059] In some embodiments, the noise reduction bump 400 is in a bump structure.

[0060] In this embodiment, refer to Figure 7 , and also includes an annular decorative ring 700 and an annular light belt member 800 . The decorative ring 700 is sleeved on the outer shell member 120 , and the light belt member 800 is sleeved on the decorative ring 700 .

[0061] Through the above structure, on the one hand, the decorative ring 700 is mounted on the outer shell 120 to improve the appearance of the overall fan light; on the other hand, the light belt 800 mounted on the decorative ring 700 can emit light to give the fan light an ambient light mode.

[0062] In some embodiments, only an annular decorative ring 700 or an annular light belt 800 is included, and the decorative ring 700 or the light belt 800 is sleeved on the outer shell 120 .

[0063] In this embodiment, a purification module is provided in the air duct 200. The purification module can be configured as a negative ion air purifier or the like.

[0064] Through the above structure and the setting of the purification module, the wind delivered by the bladeless fan device can be purified air, so as to improve the blowing comfort of the user.

[0065] In some embodiments, the purification module is disposed at the air inlet 112 .

[0066] In some embodiments, the purification module is disposed at the air outlet 300 .

[0067] The utility model also provides a fan lamp, which includes the above-mentioned bladeless fan device. The fan lamp is a ceiling fan lamp, or a ceiling fan lamp.

[0068] Through the above structure, the noise generated when the fan lamp is working can be reduced, so as to optimize the user experience.

[0069] In this embodiment, refer to Figure 1 The inner shell 130 is provided with a light-transmitting cover 630 located in the third cavity 121A, and the air outlet 300 is arranged around the light-transmitting cover 630 to form a ring-shaped air outlet gap. The gap size of the air outlet 300 is S, 1mm≤S≤6mm.

[0070] It should be noted that, in the present embodiment, the light-transmitting cover 630 is detachable so that the light-transmitting cover 630 of different shapes can be arbitrarily replaced according to the needs of the user.

[0071] Through the above structure, the size of the air outlet 300 is smaller. On the one hand, the wind speed of the wind sent out from the air outlet 300 can be increased and the air supply distance can be increased; on the other hand, the appearance of the overall fan lamp can be optimized.
