Abstract
A fan assembly includes a fan and a number of airflow guiding members. The fan includes an end board on which a number of airflow guides may be pivoted out to a horizontal position by airflow pressure but which fall back to a vertical position when the fan is not working, to effectively seal the vent when an airflow is not present.
Description
- 1. Technical Field
- The present disclosure relates to a fan assembly.
- 2. Description of Related Art
- Airflow guiding pieces mounted to fans often need to be mounted to frames first, and then the frames are mounted to the fans, thereby mounting the guiding pieces to the fans. However, the frames are costly and occupy space.
- Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an exploded, isometric view of an embodiment of a fan assembly. -
FIGS. 2 and 3 are assembled, isometric views of the fan assembly ofFIG. 1 , but showing different using states. - The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
- Referring to
FIG. 1 , an embodiment of a fan assembly includes afan 10 and a plurality of guidingmembers 20 for guiding airflow of thefan 10. - The
fan 10 includes anend board 12 including twoparallel end walls 14. Theend walls 14 face away from each other. Eachend wall 14 defines a plurality of installingholes 16. Theend board 12 defines avent 18 in a center portion. - Each guiding
member 20 includes aplate 22, twoarms 24 slantingly extending up and rearward from opposite ends of a side of theplate 22, and twopins 26 extending toward each other from inner surfaces of thearms 24. - Referring to
FIGS. 2 and 3 , in assembly, thepins 26 of each guidingmember 20 are pivotably inserted into two aligned installingholes 16 respectively in the twoend walls 14, to pivotably mount the guidingmember 20 to thefan 10. - When the
fan 10 is operating, airflow of thefan 10 will force the rotation of theplates 22 away from theend board 12, until the top sides of theplates 22 abut theend board 12. At this time, theplates 22 are perpendicular to theend board 12, to wholly expose thevent 18. - When the
fan 10 stops operating, theplates 22 will fall under gravity, to be parallel to theend board 12 and cover thevent 18, for preventing any airflow in a reverse direction. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
Claims (1)
1. A fan assembly, comprising:
a fan comprising an end board; the end board comprising two parallel end walls facing away from each other, the end walls defining a plurality of installing holes; and
a plurality of guiding members, each guiding member comprising a plate, two arms slantingly extending up and rearward from opposite ends of a top side of the plate, and two pins extending from inner surfaces of the arms, wherein the two pins of each guiding member are pivotably inserted into two of the installing holes respectively in the two end walls and aligning with each other.
