It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, the present invention provides a noise-proof fan mesh enclosure 100.
In the embodiment of the present invention, the noise-proof fan mesh enclosure 100 includes a mesh enclosure housing 10, a central cover 20, and a plurality of arc-shaped partition plates 30 connecting the mesh enclosure housing 10 and the central cover 20.
Specifically, please refer to fig. 2 simultaneously, the screen panel shell 10 is ring shape and includes air intake 11 and keeps away from the air outlet 12 of air inlet end, be equipped with a plurality of wind-guiding rib positions 13 on the inner wall of screen panel shell 10, a plurality of wind-guiding rib positions 13 equidistance intervals set up, and every wind-guiding rib position 13 is perpendicular the cross section of screen panel shell 10, center cover 20 is located the center of the air outlet 12 of screen panel shell 10, the one end of every arc baffle 30 with center cover 20 fixed connection, the one end fixed connection that the other end is close to air outlet 12 with a corresponding wind-guiding rib position 13.
It can be understood that, under the effect of the fan, the wind flow enters the mesh enclosure housing 10 from the air inlet 11, the wind flowing along the mesh enclosure housing 10 can flow out from the gap between the arc-shaped partition plates 30, and can blow towards the inner wall of the mesh enclosure housing 10 towards the wind around, and due to the existence of the plurality of wind guide rib positions 13 on the inner wall of the mesh enclosure housing 10, the random wind flow can uniformly flow along the length direction of the plurality of wind guide rib positions 13, so that the flowing directions of all the wind are consistent, and the vibration of the noise-proof fan mesh enclosure 100 is reduced, thereby achieving the effect of reducing the noise.
