Air filtering system
First Claim
1. An air filtering system for filtering air passing through a ventilating opening of an electronic device casing, the air filtering system comprising:
- an air filtering unit comprising a flexible air filtering mesh, a driving shaft, and a following shaft, the driving shaft and the following shaft configured for being rotatable positioned at opposite sides of the ventilating opening, the air filtering mesh being wrapped around the driving shaft and the following shaft with opposite ends thereof positioned to the driving shaft and the following shaft respectively, a portion of the air filtering mesh between the driving shaft and the following shaft configured for covering the ventilating opening;
an actuating unit connected to the driving shaft of the filtering unit; and
a monitoring and controlling unit comprising;
a temperature monitor configured to monitor a temperature in the electronic device casing;
a micro-processing unit; and
a timer configured to control the micro-processing unit to read a current temperature from the temperature monitor at intervals, the micro-processing unit being configured to control the actuating unit according to the read current temperature, wherein the timer is configured for controlling the micro-processing unit to read a current temperature from the temperature monitor at intervals in a manner that the newer the air filtering mesh, the longer the interval, and the older the air filtering mesh, the shorter the interval.

Abstract
An exemplary air filtering system is for filtering air passing through a ventilating opening of an electronic device casing. The air filtering system includes an air filtering unit, an actuating unit, and a monitoring and controlling unit. The air filtering unit includes a flexible air filtering mesh, a driving shaft and a following shaft. The driving and following shaft are rotatably positioned at opposite sides of the ventilating opening. The air filtering mesh is wrapped around the driving and following shafts with opposite ends thereof positioned to the driving and following shaft respectively. A portion of the air filtering mesh between the driving and following shafts covers the ventilating opening. The actuating unit is connected to the driving shaft of the filtering unit. The monitoring and controlling unit is configured to monitor a temperature in the electronic device casing and control the actuating unit according to the temperature.
