Abstract
A fan includes an interface connected to a motherboard, a fan motor, a battery, a switch connected to the battery, and a controller connected to the interface, the fan motor, the switch, and the battery. The controller includes a storage unit to store a preset timing value, a timer to count a working time of the fan motor after the motherboard is powered off, and a control unit. When the motherboard is powered on, the control unit receives a voltage from the motherboard and outputs the voltage to the fan motor. When the motherboard is powered off, the control unit controls the switch to be turned on. The battery provides a voltage to the fan motor. The control unit controls the switch to be turned off when a working time of the fan motor reaches the preset timing value.
Description
- 1. Technical Field
- The present disclosure relates to a fan.
- 2. Description of Related Art
- Various electronic devices, such as personal computers and media players, generate heat during operation. Accordingly, the electronic devices must be cooled to prevent overheating. Fans are often incorporated as heat dissipating methods. Many fans are powered by the electronic devices, when the electronic devices are turned off, the fans will stop operating. Thus, remaining heat will not be readily dissipated. Accordingly, components in the electronic devices may become overheated after the electronic devices are powered off, which shortens the life of the components. Therefore, there is room for improvement in the art.
- Many aspects of the embodiments can be better understood with reference to the following drawing. The components in the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments.
- The figure is a block diagram of a fan in accordance with an exemplary embodiment of the present disclosure.
- The disclosure, including the drawing, is illustrated by way of example and not by way of limitation. References to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
- The figure, is a
fan 100 in accordance with an exemplary embodiment including acontroller 10, aswitch 20, arechargeable battery 30, afan motor 40, and aninterface 50 connected to amotherboard 200. Thecontroller 10 includes astorage unit 11, atimer 12, acontrol unit 13, and acharging unit 14. Thestorage unit 11 stores a saturation voltage value of therechargeable battery 30 when therechargeable battery 30 is charged fully and a preset timing value. Thecharging unit 14 charges therechargeable battery 30 when a voltage of therechargeable battery 30 is less than the saturation voltage value of therechargeable battery 30, after themotherboard 200 is powered on. Thetimer 12 is used for counting a working time of thefan motor 40 after themotherboard 200 is powered off. Thecontrol unit 13 controls thefan motor 40 to stop working when the working time of thefan motor 40 reaches the preset timing value stored in thestorage unit 11. - The
controller 10 is connected to theinterface 50, theswitch 20, therechargeable battery 30, and thefan motor 40. Theswitch 20 is connected to therechargeable battery 30. - In use, the
interface 50 is connected to themotherboard 200. When themotherboard 200 is powered on, thecontrol unit 13 receives a voltage from themotherboard 200 through theinterface 50, and outputs the received voltage to thefan motor 40, to control thefan motor 40 to operate and further control thefan 100 to operate. At the same time, thecontroller 10 measures a voltage of therechargeable battery 30 and compares the measured voltage with the saturation voltage value stored in thestorage unit 11. If the measured voltage is less than the saturation voltage value, thecontrol unit 13 controls theswitch 20 to be turned on, to control thecharging unit 14 to charge therechargeable battery 30. If the measured voltage of therechargeable battery 30 is equal to the saturation voltage value, thecontrol unit 13 controls theswitch 20 to be turned off, to prevent thecharging unit 12 from charging therechargeable battery 30. - When the
motherboard 200 is powered off, thecontroller 10 does not receive a voltage from themotherboard 200. Thecontrol unit 13 controls theswitch 20 to turn on. Therechargeable battery 30 provides a voltage to thefan motor 40 through theswitch 20 and thecontroller 10, to control thefan motor 40 to operate and further controls thefan 100 to operate. At the same time, thetimer 12 times a working time of thefan motor 40. Thecontrol unit 13 controls theswitch 20 to turn off when the working time of thefan motor 40 reaches the preset timing value, to prevent therechargeable battery 30 from providing the voltage to thefan motor 40. - The
fan 100 can operate for a preset time after themotherboard 200 is powered off, so thefan 100 can dissipate remaining heat. Therefore, overheating of the components on themotherboard 200 in the electronic device is avoided, and life of the components and the electronic device is prolonged. - Even though numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
