[0032] like Figures 1 to 5 As shown, an embodiment of the utility model provides a bladeless fan that is easy to store, including a wind housing 100, a head 200 and a first driving device 300.
[0033] The wind housing 100 is bent and forms an installation space. Specifically, the wind housing 100 is U-shaped. More specifically, the wind housing 100 includes two end portions 110 and a first air outlet 120. The two end portions 110 are opposite to each other and hollowed out, that is, the end portions 110 are connected to the wind housing 100, and the first air outlet 120 is opened along the bending path of the wind housing 100.
[0034] The head 200 is arranged in the installation space and is rotatably connected with the end 110. The head 200 includes two second air outlets 2231 corresponding to and connected with the end 110, and the first driving device 300 drives the air housing 100 to rotate about the axis of the end 110. That is, the wind flow formed on the main unit 200 is discharged from the two first air outlets 2231 through the end 110 to the inside of the air housing 100, and further discharged through the first air outlet 120. The first driving device 300 can adjust the up and down shaking of the air housing 100 and change the air outlet direction of the first air outlet 120 to adapt to the use of different scenes. When it is not needed, the first driving device 300 drives the air housing 100 to a certain angle, and it is best to rotate backward 90 degrees to reduce the occupied space for easy storage.
[0035] In one embodiment, a plurality of intercepting walls 121 are provided at intervals on the first air outlet 120, and the intercepting walls 121 extend from the first air outlet 120 to the interior of the wind shell 100, dividing the first air outlet 120 and the interior of the wind shell 100 into multiple sections. It should be understood that the size of the intercepting walls 121 is adapted to the interior of the wind shell 100. When the airflow flows from the first air outlet 120 into the interior of the wind shell 100, each of the intercepting walls 121 intercepts part of the airflow in turn, so that the front, middle and rear air outlets of the first air outlet 120 can be uniform.
[0036] Optionally, in order to ensure that each of the intercepting walls 121 can intercept part of the wind flow, the extension length of the intercepting wall 121 decreases successively along the wind inlet direction. Specifically, the extension length of the intercepting wall 121 does not exceed half of the width of the wind shell 210. Furthermore, the difference in the extension length of the intercepting wall 121 is irregular, and the extension length of the intercepting wall 121 located upstream is greater than that of the intercepting wall 121 located downstream. It should be noted that since the wind flow discharged to the tail end of the wind shell 100 becomes smaller, for this reason, the extension lengths of the intercepting walls 121 at the tail end are preferably the same to ensure the air output.
[0037] In one embodiment, the intercepting wall 121 is tilted toward the air inlet direction to correct the wind direction so that the wind can flow out vertically from the first air outlet 120 and can be discharged more smoothly from the first air outlet 120, thereby reducing noise.
[0038] In one embodiment, the head 200 includes a housing 210 and a fan assembly 220 installed inside the housing 210 , and the end portion 110 is rotatably connected to the housing 210 .
[0039] Optionally, the fan assembly 220 includes a centrifugal wind wheel 221, a vortex shell 222 and a guide pipe 223. The centrifugal wind wheel 221 has the advantages of gathering wind and high wind pressure, and can increase the air output; the vortex shell 222 is fixed inside the casing 210, the centrifugal wind wheel 221 is arranged on the vortex shell 222, and the vortex shell 222 has a third air outlet 2221; the second air outlet 2231 is a port of the guide pipe 223, and the third air outlet 2221 is connected to the guide pipe 223 from the side wall of the guide pipe 223 , that is, the centrifugal wind wheel 221 drives the surrounding air to form a wind flow, and the wind flow is discharged to the guide pipe 223 through the third air outlet 2221, and two wind flows are formed and discharged from the ports of the guide pipe 223 to the air guide cavity 210 respectively; specifically, the guide pipe 223 is transversely arranged at the third air outlet 2221, that is, the air outlet direction of the guide pipe 223 is perpendicular to the air outlet direction of the third air outlet 2221; more specifically, the guide pipe 223 and the volute 222 are integrally formed to ensure the stability of the structure.
[0040] In one embodiment, the inner wall of the guide tube 223 is provided with a diverter wall 2232 corresponding to the third air outlet 2221, and the diverter wall 2232 is conical. The wind flow discharged from the third air outlet 2221 is evenly diverted to the two second air outlets 2231 through the diverter wall 2232, thereby ensuring that the air volume on both sides of the two wind shells 100 is the same, and the diverter wall 2232 makes the wind flow smoother and can reduce noise.
[0041] In one embodiment, in order to realize that the first driving device 300 can adjust the up and down shaking of the wind housing 100, specifically, the first driving device 300 includes a first motor 310, a driving gear 320 and a driven gear 330, wherein the first motor 310 is fixed inside the housing 210, the driving gear 320 is installed on the shaft of the first motor 310, the driven gear 320 is installed on one of the ends 110 and is located inside the housing 210, the driving gear 320 is meshed and connected with the driven gear 330, that is, the wind housing 100 is driven to rotate by the first motor 310.
[0042] In one embodiment, the bladeless fan further includes a second motor 400 and a support base 500, wherein the support base 500 includes a vertically arranged connecting rod 510, wherein the connecting rod 510 is rotatably connected to the housing 210, and the second motor 400 is fixed to the inner bottom wall of the housing 210, and the shaft of the second motor 400 is fixedly connected to the connecting rod 510. That is, the housing 210 can be driven to rotate on the connecting rod 510 by the second motor 400 to achieve left and right shaking of the head to adapt to different usage scenarios.
[0043] The support base 500 further includes a bottom shell 520, and the bottom shell 520 is fixed to the lower end of the connecting rod 510 so that the bladeless fan can stand on the ground.
[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
