Abstract

The invention provides an automatic dust removing fan device and a dust removing method for the same. The automatic dust removing fan device comprises a motor, an impeller and a control chip; under normal conditions, the motor drives the impeller to rotate along a cooling direction; when the control chip detects that a special condition exists, the control chip controls the motor to reverse the operation, so that the motor drives the impeller to rotate along a dust removing direction, thereby automatically removing the dust in the fan device.

Description

technical field [0001] The invention relates to a fan device, in particular to an automatic dust exhaust fan device. Background technique [0002] Generally, cooling fans are installed inside most existing notebook computers to reduce the temperature inside the computer. However, after a general cooling fan is used for a period of time, dust will accumulate at the cooling outlet, which will affect the fan speed and cooling efficiency. Therefore, the user needs to remove the cooling fan from the interior of the notebook computer by himself, so as to clean or replace the cooling fan. However, since the interior of the notebook computer is provided with numerous computer parts in a limited space, the cooling fan cannot be easily disassembled, which causes difficulties for users to clean. [0003] In order to solve the above problems, the prior art provides a dust exhaust fan device, which utilizes the forward rotation and reverse rotation of the fan to blow away the dust gath...
