Description

Technical Field

[0001] The utility model relates to the field of air supply equipment, in particular to a bladeless fan and a fan lamp. Background Art

[0002] A bladeless fan is installed on the ceiling to deliver air and drive the air flow below it. The blades of the bladeless fan are designed to be built-in. Compared with traditional multi-blade fans, it occupies less space and has a simple and compact appearance. Therefore, it is increasingly favored by consumers.

[0003] According to the built-in design of the fan blade, some bladeless fans include a fan body and a fan blade. The fan body is provided with an air duct and a downwardly arranged annular air outlet connected to the air duct. The fan blade is arranged in the air duct. Figure 5 When the above-mentioned bladeless fan blows air downward, the high-speed airflow blown out from the air outlet will quickly take away the air in the inner area A below the air outlet, causing low pressure in the area A. Therefore, the air in the outer area B below the air outlet will move toward the area A, causing the overall air outlet of the bladeless fan to move toward its central axis, thereby shortening the air supply distance of the bladeless fan and reducing the air supply area, affecting the user's blowing experience.

[0004] In this regard, in the existing technology, some technicians will add a shielding block in the air duct to make the bladeless fan discharge air in a non-full ring, that is, the air in the area below the outer side of the air outlet corresponding to the shielding block will be replenished into area A, avoiding low pressure in area A, thus solving the above problem. However, the inventor found through many experiments that although the addition of a shielding block can solve the above problem, the bladeless fan still has the problems of high working noise and poor user experience.

[0039] Reference Figures 1 to 5 The utility model embodiment provides a bladeless fan, which includes a fan body 100 and a sound absorbing block 200.

[0040] The fan body 100 is provided with an air duct 300, and an air inlet 112 and an air outlet 400 connected with the air duct 300. The air outlet 400 is annular and arranged downward. The air outlet 400 is provided with an air outlet area and a shielding area. A shielding block 122 is provided in the air duct 300. The shielding block 122 can prevent the air in the air duct 300 from being sent out from the shielding area of ​​the air outlet 400. The sound absorbing block 200 is provided in the air duct 300. The sound absorbing block is a porous structure, and specifically, the sound absorbing block is a sound absorbing cotton block; the gap size of the air outlet 400 is S, 1mm≤S≤6mm.

[0041] It can be understood that the shielding block 122 can block the air in the air duct 300 from being discharged from the shielding area of ​​the air outlet 400, that is, the air in the air duct 300 can only be discharged from the air outlet area of ​​the air outlet 400, and the bladeless fan does not discharge air in a full ring.

[0042] Through the above structure, the sound absorbing block 200 is arranged in the air duct 300, and the noise sound waves generated in the air duct 300 will enter the sound absorbing block 200, and the sound waves will vibrate in the pores in the sound absorbing block 200. Due to the viscous resistance of the air and the friction of the sound waves in the pores of the sound absorbing block 200, most of the sound energy of the sound waves is converted into heat and consumed. Therefore, the sound absorbing block 200 can absorb most of the noise generated in the air duct 300, thereby reducing the noise generated by the bladeless fan when working and optimizing the user experience.

[0043] The fan body 100 includes a ceiling cup 110 , an outer shell 120 and an inner shell 130 .

[0044] 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 outer shell 120 is provided with a shielding block 122 located in the fourth cavity 121B. The side wall of the opening and the inner shell 130 are spaced apart to form an air outlet 400 connected to the fourth cavity 121B. The fourth cavity 121B is connected to the first cavity 111 to form an air duct 300.

[0045] The sound absorbing block 200 is disposed in the air duct 300. For details, refer to Figures 2 to 4 The shielding block 122 is provided with a receiving cavity 122A and a first through hole 122B communicating with the receiving cavity 122A and the air duct 300 , and the sound absorbing block 200 is provided in the receiving cavity 122A.

[0046] Through the above structure, on the one hand, the noise sound waves in the air duct 300 will enter the sound absorbing block 200 through the first through hole 122B, and the sound absorbing block 200 in the accommodating cavity 122A can absorb most of the noise generated in the air duct 300; on the other hand, the sound absorbing block 200 is arranged in the accommodating cavity 122A, which will not occupy additional space in the air duct 300, and will not affect the arrangement of other components in the air duct 300, and can make the overall bladeless fan design more simple and compact.

[0047] In some embodiments, the shielding block 122 is disposed on the inner shell 130 .

[0048] In some embodiments, both the outer shell 120 and the inner shell 130 are provided with the above-mentioned shielding block 122 .

[0049] In some embodiments, the sound absorbing block 200 is disposed in the air duct 300 . Specifically, the sound absorbing block 200 is disposed in the first cavity 111 , that is, the sound absorbing block 200 is disposed in the ceiling cup 110 .

[0050] In order to reduce the probability of the sound absorbing block 200 moving in the accommodating cavity 122A and generating noise, refer to Figure 2 and Figure 4 A cavity wall of the accommodating cavity 122A is provided with a positioning block 122A1 , and the sound absorbing block 200 is provided with a positioning hole 210 , and the positioning block 122A1 is inserted into the positioning hole 210 .

[0051] In some embodiments, the positioning hole 210 is disposed on the cavity wall of the accommodating cavity 122A, and the positioning block 122A1 is disposed on the sound absorbing block 200 .

[0052] In this embodiment, refer to Figure 2 and Figure 3 The outer shell 120 is provided with a second through hole 123 , and the first cavity 111 is connected with the fourth cavity 121B through the second through hole 123 , wherein, in addition to the sound absorbing block 200 provided in the accommodating cavity 122A, there is a sound absorbing block 200 provided at the second through hole 123 .

[0053] Through the above structure, the sound absorbing block 200 disposed at the second through hole 123 and the sound absorbing block 200 disposed in the accommodating cavity 122A work together to further reduce the noise generated by the bladeless fan during operation, thereby further optimizing the user experience.

[0054] In some embodiments, the bladeless fan may be provided with only one sound absorbing block 200 , and the sound absorbing block 200 is provided at the second through hole 123 .

[0055] The sound absorbing block 200 is disposed at the second through hole 123. For details, refer to Figure 2 and Figure 3 The outer shell 120 is provided with a sound insulation ring cover 500 located in the fourth cavity 121B. The sound insulation ring cover 500 is penetrated through the second through hole 123 , and the sound absorbing block 200 is sleeved on the sound insulation ring cover 500 .

[0056] It is understandable that after the air enters the air duct 300 from the air inlet 112 , it flows through the first cavity 111 , the inner hole of the sound insulation ring cover 500 and the fourth cavity 121B in sequence, and finally blows out from the air outlet area of ​​the air outlet 400 .

[0057] In this embodiment, refer to Figure 2 and Figure 3The fourth cavity 121B is provided with a fan blade 600, which is arranged opposite to the second through hole 123, and the sound insulation ring cover 500 is sleeved on the top of the fan blade 600. The fan blade 600 can rotate to drive the air in the air duct 300 to flow.

[0058] Through the above structure, the sound insulation ring cover 500 is sleeved on the top of the fan blade member 600, so as to compress the thickness of the designed bladeless fan, so that the overall bladeless fan can be designed to be more simple and compact.

[0059] The utility model also provides a fan lamp, which includes the above-mentioned bladeless fan. The fan lamp is a ceiling fan lamp, or a ceiling fan lamp.

[0060] Through the above structure, the noise generated during operation can be reduced, so as to optimize the user experience.
