Claim Text:
1. A device for monitoring a lifetime of fan bearings, which is applied to a fan, comprising: a base having a bearing sleeve having a bearing hole for receiving at least one bearing having a shaft hole, the bearing sleeve protruding from the center of the base; at least one sensing unit selectively disposed on the bearing sleeve or on the at least one bearing for sensing a temperature of the corresponding bearing to generate a temperature sensed signal; a processing unit electrically connected to the at least one sensing unit and generating an informing signal based on comparison of the received temperature sensed signal and an internal predetermined temperature value; and a control plate disposed on the base and being adjacent to the bearing sleeve, wherein the processing unit is disposed on one side of the control plate and is electrically connected to the control plate; wherein a silicon steel plate set is sleeved to the bearing sleeve and is electrically connected to the control plate, wherein the bearing sleeve is pivoted to a fan wheel having a shaft, wherein one end of the shaft is affixed to the fan wheel and the other end thereof is rotatably disposed in the corresponding shaft hole, wherein the fan wheel covers the silicon steel plate set; and wherein a communication interface is provided on the control plate, wherein the communication interface is connected to an electronic device, wherein the processing unit transmits the informing signal to the electronic device via the communication interface, such that a user can know the information if the bearing is abnormal or about the lifetime prediction of the bearing via the informing signal displayed by the electronic device.
