Abstract: A deflection device and an electronic device are disclosed. The deflection device is located in the electronic device for guiding airflow generated by a fan device to at least one electronic component. The deflection device includes a first fixed part and a plurality of strip structures. The first fixed part is used for fixing the deflection device in a suitable position. One end of each of the strip structures is connected to the first fixed part and able to undergo compression deformation independently such that forms a first shape when not compressed or a second shape when compressed. When the deflection device is fixed in a suitable position of the electronic device and close to the electronic component, the shape of the at least one strip structure is changed from a first shape to a second shape for guiding the airflow to the electronic component.

Abstract: A dustproof device includes a first component, a second component and an engaging mechanism. The first component includes a first plug body which is pluggable into the first standard connection port. The second component includes a second plug body which is pluggable into the second standard connection port. The engaging mechanism includes a first engaging part which is disposed on the first component, and a second engaging part which is disposed on the second component and which is removably engageable with the first engaging part. The first component is removably connected to the second component by virtue of removable engagement between the first engaging part and the second engaging part.

Abstract: A rotor of a motor includes a shaft, a magnetically conductive shell and a connecting element. The shaft has a groove formed at one end of the shaft. The central portion of a top wall of the magnetically conductive shell has at least one extending portion disposed adjacent to the groove, and at least one part of the extending portion is radially projected onto the groove. The connecting element connects the end of the shaft and the extending portion of the magnetically conductive shell. A fan including above-mentioned rotor is also disclosed.
