Abstract
A fan assembly includes a fan, a guiding board, and a weight. The fan includes an end board defining a vent. The guiding board is pivotably mounted to a top of the end board. The weight is detachably mounted to the guiding board.
Description
- 1. Technical Field
- The present disclosure relates to a fan assembly.
- 2. Description of Related Art
- A weight of guiding boards mounted to fans is fixed. As a result, when the fans operate, the guiding boards extend away from the fan at a fixed angle, which cannot be adjusted to adjust a direction of airflow generated by the fan.
- 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 shows an embodiment of a fan assembly comprising a fan and a guiding board, wherein the fan is not operating, and the guiding board is substantially parallel to the fan. -
FIG. 2 is similar toFIG. 1 , but shows the fan operating, and the guiding board slanted relative to the fan at a first angle. -
FIG. 3 is similar toFIG. 2 , but shows the guiding board slanted relative to the fan at a second angle. -
FIG. 4 is an enlarged view of the circled portion IV ofFIG. 3 . - 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
FIGS. 1-3 , an embodiment of afan assembly 10 comprises afan 20, a guidingboard 30, twoweights 40, and twofasteners 50. In one embodiment, thefasteners 50 are made of rubber. - The
fan 20 comprises anend board 22. A substantially central portion of theend board 22 defines avent 24. Twofixing pieces 26 protrude substantially perpendicularly from opposite sides, respectively, of a top portion of theend board 22. - Two
pins 32 extend from opposite end portions of a top portion of the guidingboard 30, to be pivotably received in thefixing pieces 26. The guidingboard 30 is pivotably mounted to thefan 20 through the twopins 32. Tworods 34 extend from opposite end portions of a bottom portion of the guidingboard 30. - When the
fan 20 is not operating, the guidingboard 30 is substantially parallel to theend board 22 and covers thevent 24. - Referring to
FIG. 2 , when thefan 20 operates without theweights 40, airflow generated by thefan 20 pushes the guidingboard 30 to rotate away from theend board 22, thereby making the guidingboard 30 slant relative to theend board 22 at a first angle. -
FIGS. 3 and 4 show that theweights 40 are fitted about therods 34. Thefasteners 50 are then fitted about therods 34 and abut thecorresponding weights 40 to fix theweights 40 to the guidingboard 30. Theweights 40 add weight to the guidingboard 30. Referring toFIG. 3 , when thefan 20 operates with theweights 40, the guidingboard 30 is slanted relative to theend board 22 at a second angle, which is less than the first angle. Therefore, when thefan 20 operates, theweights 40 can be added or removed from therods 34 to adjust a direction of airflow. - In another embodiment, more guiding
boards 30 andmore weights 40 can be added. For example, two guidingboards 30 can be mounted to thefan 20 side-by-side. One of the guidingboards 30 comprises a number ofweights 40, and the other guidingboard 30 has noweights 40, so that the airflow can be adjusted in different directions. - 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 (5)
1. A fan assembly, comprising:
a fan comprising an end board defining a vent;

2. The fan assembly of claim 1 , wherein the end board comprises two fixing pieces protruding from opposite ends of the top portion of the end board, the guiding board comprises two pins extending out from opposite ends of a top portion of the guiding board, to be pivotably received into the fixing pieces.
3. The fan assembly of claim 1 , wherein the guiding board comprises a rod extends from an end of a bottom portion of the guiding board, and the at least one weight is mounted to the rod.
4. The fan assembly of claim 3 , further comprising a fastener mounted to the rod and abutted the weight.
5. The fan assembly of claim 4 , wherein the fastener is made of rubber.
