As shown in fig. 1, fig. 2, and fig. 3, an embodiment of the present application provides a fan control system, which is applied to an electronic device, and in practical applications, the electronic device may be a notebook computer, a desktop computer, an air conditioner, or another electronic device, which is not limited herein. In the following detailed description, the working mode and the technical effect of the fan control system will be further described by taking the electronic device as a notebook computer as an example.
A fan control system for use in an electronic device including a fan 10, the fan control system comprising: the setting module 20 is located at a user end of the electronic device to receive a user instruction, for example, a keyboard of the notebook computer of this embodiment has a fan control function key, and the fan control function key can be used as an implementation manner of a component for receiving the user instruction in the setting module 20; a control circuit 30 electrically connected to the fan 10 and the setting module 20 for analyzing the user command and generating a corresponding control signal; wherein the control signal is used for controlling the fan 10 to perform corresponding rotation operation.
The fan control system further includes a display unit 21 located in the setting module 20 to display the temperature information of the electronic device and the fan status of the fan 10, wherein the display unit 21 at least includes a first display object 211 for triggering the fan 10 to perform a rotation operation.
In a specific implementation process, when the electronic device is a notebook computer, the display unit 21 is a fan rotation control interface that can be displayed on a display of the notebook computer, and a user can know a current state of the notebook computer through the interface, for example, a temperature of a central processing unit is 40 degrees, a fan reverse rotation speed is 2000 revolutions per minute, and the like; the first display object 211 is a rotation control icon in the fan rotation control interface, and of course, the rotation control icon may be a reverse rotation control icon or a forward rotation control icon, and the fan rotation interface may further include other icons, such as a current temperature icon, a dust removal start icon, a heat dissipation start icon or a reverse rotation speed icon, a reverse rotation duration icon, and the like.
The fan control system is also provided with a heat dissipation module 40 for dissipating heat of the electronic equipment; meanwhile, in order to achieve convenient dust removal, the fan control system further comprises a dust collecting device 50, which is located beside the heat dissipation module 40 and is used for collecting all or part of dust which is adsorbed and accumulated on the heat dissipation module 40 and is taken away with air after the fan 10 executes a fan reversal command in the user command. When the electronic device is the notebook computer, the heat dissipation performance of the heat dissipation module 40 of the notebook computer is reduced due to the accumulation of dust, and at this time, after the fan reverse rotation dust removal operation is performed, the dust is concentrated in a certain area inside the notebook computer, and the dust collection device 50 is installed in the certain area, so that the accumulated dust can be quickly removed.
In an embodiment of the present application, the fan control system further includes: the fan driving structure 60 is connected to the control circuit 30, and the fan driving structure 60 includes a power port 61 and a first fan port 62 different from the power port 61. The control circuit 30 includes a second fan port 31, the control circuit 30 is connected to the fan driving structure 60 through the first fan port 62 and the second fan port 31, and the user command is transmitted to the fan driving structure 60 through the first fan port 62 and the second fan port 31.
In a specific implementation process, when a first operation is performed on the first display object 211, the setting module 20 transmits first operation information corresponding to the first operation to the control circuit 30, the control circuit 30 generates a fan rotation instruction based on the first operation information and transmits the fan rotation instruction to the fan driving structure 60, and the fan driving structure 60 receives and executes the fan rotation instruction to implement forward rotation or reverse rotation of the fan 10.
The above process is an example of the notebook computer in combination with the electronic device: when the notebook computer needs to perform the reverse dust removal operation, a reverse control icon on the fan rotation control interface is clicked, the control circuit 30 generates a fan reverse instruction and transmits the fan reverse instruction to the fan driving structure 60, and the fan driving structure 60 controls the fan 10 to perform reverse rotation to perform the dust removal operation on the heat dissipation module 40; when the notebook computer needs to perform a heat dissipation operation, the forward rotation control icon on the fan rotation control interface is clicked, the control circuit 30 generates a fan forward rotation instruction and transmits the fan forward rotation instruction to the fan driving structure 60, and the fan driving structure 60 controls the fan 10 to perform a heat dissipation operation on the heat dissipation module 40.
In the embodiment of the present application, in order to store the user command including the fan rotation parameter, the fan control system further includes a storage unit 70 for storing the user command, where the user command includes a fan rotation control command, a reverse rotation speed control command, a reverse rotation time indication command, and a heat dissipation time indication command, and the fan rotation control command includes a fan forward rotation command for heat dissipation and a fan reverse rotation command for dust removal. In the embodiment of the present application, in order to be able to display the user instruction stored in the storage unit 70 on the display unit 21, the display unit 21 of the fan control system is further configured to display a user instruction setting interface 212, and the user instruction setting interface 212 is able to display the user instruction stored in the storage unit 70. Such as: at present, the notebook computer needs to be subjected to dust removal operation, the user instruction is the reversal rotating speed of 2000 rpm, the reversal duration is 3 minutes, and at this time, the instruction is displayed on the user instruction setting interface 212.
In the embodiment of the present application, the control circuit 30 is further configured to determine whether the electronic device is in a state requiring heat dissipation or dust removal, when the electronic device is in the state requiring heat dissipation, the control circuit 30 generates and transmits a fan forward rotation instruction to the fan driving structure 60, and the fan driving structure 60 executes the fan forward rotation instruction to drive the fan 10 to perform forward rotation, so as to dissipate heat of the electronic device; when the electronic device is in a state requiring dust removal, the control circuit 30 generates and transmits a fan reverse rotation instruction to the fan driving structure 60, and the fan driving structure 60 executes the fan reverse rotation instruction to drive the fan 10 to reverse rotation, so that the electronic device performs dust removal operation.
In a specific implementation process, when the electronic device is the notebook computer and the notebook computer is in a state requiring dust removal, the control circuit 30 determines whether the fan 10 has a reverse rotation condition, and obtains a first determination result; and when the first judgment result is yes, generating a fan reverse rotation instruction, and when the first judgment result is no, generating and sending a first prompt message for prompting that a user of the electronic equipment cannot control the fan 10 to reverse currently to the display unit 21. For example, when the notebook computer is currently executing an important program or running a large program, the reverse rotation dust removal operation may affect the heat dissipation effect of the heat dissipation module 40, at this time, it is not recommended to start the fan reverse rotation dust removal operation, that is, the fan 10 does not have the reverse rotation condition, if the first determination result is no, the display unit 21 may display a prompt message, such as: at this time, the fan is performing a heat dissipation operation, please start the dust removal function later.
In the embodiment of the present application, the amount of dust accumulated on the heat dissipation module 40 is detected by detecting the temperature in the electronic device. Specifically, the fan control system further includes: the temperature detecting device 80 is connected to the display unit 21 and the control circuit 30, and is configured to detect a current temperature value of a predetermined area in the electronic device, and send the current temperature value to the display unit 21 and the control circuit 30, so that the current temperature value can be displayed on the display unit 21.
In a specific implementation process, still taking the notebook computer as an example, the temperature detection device 80 is disposed inside the notebook computer housing, the temperature detection device 80 may be integrated on a motherboard of the notebook computer or may be an independent device, and the predetermined area may be a first area corresponding to a central processing unit of the notebook computer or a second area corresponding to a display card of the notebook computer; and when the preset area is the first area, the current temperature value is the first temperature of the central processing unit, and when the preset area is the second area, the current temperature value is the second temperature value of the display card. If dust accumulation exists on the heat dissipation module 40 of the notebook computer, the heat dissipation effect of the heat dissipation module 40 is reduced, and thus, the first temperature value of the first area corresponding to the central processing unit is increased, or the second temperature value of the second area corresponding to the display card is increased. This indicates that the dust accumulation degree on the heat dissipation module 40 is closely related to the current temperature value of the predetermined area, and the dust accumulation degree on the heat dissipation module 40 can be obtained by detecting the current temperature value.
Based on the relationship between the dust accumulation degree and the current temperature value, in the embodiment of the present application, a temperature threshold indicating that dust removal is required for the heat dissipation module 40 is set, which may specifically be a first preset temperature, and when the temperature detection device 80 detects the first temperature value or the second temperature value, the control circuit 30 determines whether the first temperature value or the second temperature value reaches the first preset temperature, so as to obtain a second determination result; when the second judgment result is yes, generating and sending a second prompt message for prompting whether the user of the electronic device starts the fan reverse rotation dust removal function to the display unit 21; the first preset temperature indicates that all or part of dust adsorbed and accumulated on the heat dissipation module 40 needs to be removed, and when the first previous temperature value or the second temperature value is the first preset temperature, the reverse rotation speed of the fan 10 is the first preset rotation speed, and the reverse rotation time of the fan 10 is the first preset time. Such as: when the first temperature value is 60 degrees, and the first preset temperature is 55 degrees, since 60 degrees is greater than 55 degrees, the second determination result is yes, and at this time, a first prompt message for prompting a user of the notebook computer whether to start the fan reversal dust removal function is generated and sent to the display unit 21, in this embodiment, when the corresponding first preset temperature is 55 degrees, the first preset rotation speed is 2500 rpm; the first preset time period is 2 minutes. For another example, when the first temperature value is 50 degrees and the first preset temperature is 55 degrees, the second determination result is no because 50 degrees is less than 55 degrees, and at this time, it indicates that dust removal is not required, and therefore, the fan 10 is kept rotating forward.
The higher the temperature of the cpu of the notebook computer is, the more dust accumulated in the heat dissipation module 40 is, the worse the heat dissipation performance of the heat dissipation module 40 is, and the normal operation of the notebook computer may be seriously affected by the heat dissipation performance, in order to ensure the normal operation of the notebook computer, when the temperature detection device 80 detects that the first temperature value or the second temperature value is increased, that is: when the first temperature value or the second temperature value is greater than the first preset temperature, the control circuit 30 determines whether the first temperature value or the second temperature value reaches the second preset temperature, and obtains a third determination result; if the third judgment result is yes, a third prompt message for prompting whether the user of the electronic device starts the fan reverse rotation dust removal function is generated and sent to the display unit 21; the second preset temperature indicates that all or part of dust adsorbed and accumulated on the heat dissipation module 40 needs to be removed, and when the first temperature value or the second temperature value is the second preset temperature, the reverse rotation speed of the fan 10 is a second preset rotation speed higher than the first preset rotation speed, and the reverse rotation time of the fan 10 is the first preset time. Such as: when the first temperature value is 68 degrees, the second preset temperature value is 65 degrees, and the 68 degrees are greater than 65 degrees, the third determination result is yes, a second prompt message for prompting whether the user of the notebook computer starts the fan reverse rotation dust removal function or not is generated and sent to the display unit 21, in this embodiment, when the corresponding second preset temperature value is 65 degrees, the second preset rotation speed is 3000 rpm.
When the first temperature value of the first area corresponding to the central processing unit or the second temperature value of the second area corresponding to the display card continuously rises and exceeds the second preset temperature to reach a third preset temperature, the control circuit 30 judges whether the first temperature value or the second temperature value reaches the third preset temperature or not, and obtains a fourth judgment result; if the fourth judgment result is yes, a fourth prompt message for prompting whether the user of the electronic device starts the fan reverse rotation dust removal function is generated and sent to the display unit 21; the third preset temperature indicates that all or part of dust adsorbed and accumulated on the heat dissipation module 40 needs to be removed, and when the first temperature value or the second temperature value is the third preset temperature, the reverse rotation speed of the fan 10 is a third preset rotation speed higher than the first preset rotation speed, and the reverse rotation time of the fan 10 is a second preset time higher than the first preset time. Such as: when the first temperature value is 72 degrees, the third preset temperature value is 70 degrees, and the 72 degrees are greater than 70 degrees, the fourth determination result is yes, a third prompt message for prompting whether the user of the notebook computer starts the fan reverse rotation dust removal function or not is generated and sent to the display unit 21, in this embodiment, when the third preset temperature value is 70 degrees, the third preset rotation speed is 3500 rpm, and the second preset duration is 5 minutes.
To facilitate user control over the rotation of the fan 10, the user command setting interface 212 further includes an input area 2121 for inputting user commands, wherein: when a first input operation to the input region 2121 is detected, by responding to the first input operation, a first operation parameter corresponding to the first input operation can be input and displayed in the input region 2121; or, based on the second prompt information or the third prompt information or the fourth prompt information, displaying a second operation parameter or a third operation parameter or a fourth operation parameter respectively corresponding to the second prompt information or the third prompt information or the fourth prompt information in the input area 2121; the first operation parameter is specifically the reverse rotation speed, the reverse rotation time and the heat dissipation time; the second operating parameter or the third operating parameter or the fourth operating parameter is in particular a reversal speed and/or a reversal time.
In a specific implementation process, still taking the notebook computer as an example, the display unit 21 is a fan rotation control interface, the input region 2121 is an input frame located in the user instruction setting interface 212, and a user can input corresponding fan rotation parameter values, such as a reverse rotation speed, a reverse rotation duration, a heat dissipation duration, and the like, in the input frame according to the first temperature value or the second temperature value displayed on the display unit 21; or the notebook computer may recommend a default fan rotation parameter value to the user according to a first temperature value of a first area corresponding to the central processing unit or a second temperature value of a second area corresponding to the display card, and if the first temperature value is 60 degrees, the default fan rotation parameter value reaches the first preset temperature of 55 degrees and does not reach the second preset temperature of 65 degrees, and the system defaults that the inversion rotation speed at the first preset temperature is 2500 rpm and the inversion time is 2 minutes, at this time, the notebook computer may display the parameter value in the input area 2121 for the user to refer to.
In the embodiment of the present application, the setting module 20 is further configured to receive the first operating parameter, the second operating parameter, the third operating parameter, or the fourth operating parameter and store the received first operating parameter, the second operating parameter, the third operating parameter, or the fourth operating parameter in the storage unit 70. For example, when the first operating parameter is set to the reverse rotation speed of 2500 rpm for 2 minutes, the first operating parameter is stored in the storage unit 70 so that the control circuit 30 can obtain the instruction and send the instruction to the fan driving structure 60 to control the fan 10 to perform reverse rotation dust removal.

Specifically, when the fan rotation control instruction is the fan reverse rotation instruction, the fan driving structure receives and executes the fan reverse rotation instruction, so that the fan can be controlled to be reversed, and the heat dissipation module is dedusted; therefore, according to the scheme in the embodiment of the application, the fan can be controlled to rotate reversely at any time by responding to the operation of the user on the first display object, so that the dust removal is realized, and the technical effect of controlling the fan to rotate reversely at any time is further realized.
Thirdly, in the scheme of the embodiment of the application, the rotation parameters of the fan, such as reverse rotation time, reverse rotation speed and heat dissipation time, can be set by utilizing the input area on the display unit; or the current temperature in the shell is detected through the temperature detection device, the corresponding rotating parameter value for the fan to rotate reversely is provided according to the current temperature, and the rotating parameter value is displayed in the input area.
In the embodiment of the present application, when the fan rotation control instruction received by the control circuit is the fan reverse rotation instruction, it is determined whether the fan has a reverse rotation condition, and when the fan meets the reverse rotation condition, the fan is controlled to reverse rotation, otherwise, the fan is allowed to rotate forward, for example: when the electronic equipment executes an important program or runs a large program, the heat dissipation effect of the electronic equipment is affected by the operation of reversal dust removal, at the moment, the control circuit generates the first prompt message to the display unit to inform the user that the fan reversal instruction cannot be executed currently, and therefore the technical effect of dust removal on the premise of meeting the heat dissipation requirement of the electronic equipment is achieved.
