[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] The following combination Figures 1 to 5 A dust removal system according to an embodiment of the present invention is described.

[0045] like Figure 1As shown, the dust removal system provided by the embodiment of the present invention includes: a detection device 3, which is used to detect the real-time temperature on the opposite sides of the dustproof net 6; a dust removal device 2, which includes a dust removal component 21 and a driving component, the dust removal component 21 is used to be arranged on one side of the dustproof net 6, and the driving component is used to drive the dust removal component 21 to move relative to the dustproof net 6, so that the dust removal component 21 cleans the dust attached to the dustproof net 6; a controller 4, which is connected to the detection device 3 and the dust removal device 2, and the controller 4 is used to connect to the cooling fan 5, determine the preset dust removal threshold, and control the working state of the dust removal device 2 and the working state of the cooling fan 5 based on the relationship between the difference in real-time temperature and the preset dust removal threshold.

[0046] Specifically, the device comprises a housing 1, with a detection device 3, a dust removal device 2, a cooling fan 5, and a controller 4 mounted in corresponding locations within the housing 1. The detection device 3, dust removal device 2, and cooling fan 5 are connected to the controller 4. The housing 1 is provided with an opening for air circulation, and a dust screen 6 is mounted within the opening. The dust screen 6 can be secured to the opening via a support frame 7. Multiple components are mounted within the housing 1. These components generate heat when in operation, and these multiple components are defined as heat sources.

[0047] The cooling fan 5 is spaced apart from the dust screen 6, and the cooling fan 5 has a first working state, a second working state, and a shutdown state. In the first working state, the cooling fan 5 is in an exhaust mode, and the cooling fan 5 can draw the cold air outside the device into the housing 1 through the dust screen 6 to dissipate heat from the heat source and ensure reliable operation of the device. In the second working state, the cooling fan 5 is in a blowing mode, and the cooling fan 5 blows air out of the housing 1, and the airflow passes through the dust screen 6. When the device is not running, the cooling fan 5 is in a shutdown state. The cooling fan 5 includes multiple fans, and the number of fans is not specifically limited. Multiple fans are arranged side by side.

[0048] The detection device 3 is disposed near the dust screen 6. The dust screen 6 has a first side and a second side that are opposite to each other. The first side is opposite to the interior of the housing 1, and the second side is opposite to the exterior of the housing 1. The detection device 3 includes a first temperature detection unit and a second temperature detection unit. The first temperature detection unit is used to detect the temperature of the first side of the dust screen 6 to obtain a first temperature of the first side; the second temperature detection unit is used to detect the temperature of the second side of the dust screen 6 to obtain a second temperature of the second side. The real-time temperature includes the first temperature and the second temperature. After the device has been running for a period of time, a certain amount of dust will accumulate on the dust screen 6. The dust will affect the heat dissipation effect of the device. As the amount of dust accumulates, the first temperature tends to gradually rise. The second temperature is the same as the ambient temperature outside the device and is relatively stable. It is understood that the first temperature is greater than or equal to the second temperature.

[0049] The dust removal device 2 is positioned adjacent to the dust screen 6 and includes a dust removal member 21 and a drive member. The dust removal member 21 may be a scraper, a brush, or a roller brush, or any combination thereof. The length, width, and height of the dust screen 6 are configured based on the actual needs of the device. The length of the dust removal member 21 matches the length of the dust screen 6. The dust removal member 21 contacts the dust screen 6 and is capable of reciprocating in the height direction between one end and the other end of the dust screen 6 to clean dust adhering to the dust screen 6. The drive member is used to drive the dust removal member 21 to move.

[0050] During the operation of the device, when the device just starts to run, the cooling fan 5 is in the first working state, and the cooling fan 5 draws air to dissipate heat for the device. During the operation of the device, the current speed of the cooling fan 5 is defined as the real-time speed of the cooling fan 5, and the real-time speed matches the operating conditions of the device. The dust removal system has multiple dust removal thresholds, and the dust removal thresholds correspond to the speed of the cooling fan 5. The speed of the cooling fan 5 can be divided into percentages, for example, a section is divided at intervals of 5% or 10%, thereby dividing it into multiple speed sections from small to large according to the speed value. Each speed section corresponds to a dust removal threshold, and multiple speed sections have multiple dust removal thresholds. It can be understood that the greater the speed of the cooling fan 5, the smaller the dust removal threshold. The controller 4 is connected to the cooling fan 5, and the controller 4 can obtain the real-time speed of the cooling fan 5. According to the speed section to which the real-time speed belongs, the dust removal threshold corresponding to the speed section is obtained, and the dust removal threshold corresponding to the real-time speed is defined as the preset dust removal threshold.

[0051] The following describes the dust removal system's operating process in detail. During the initial operation of the device, cooling fan 5 draws air into housing 1 to dissipate heat. The real-time speed of cooling fan 5 is obtained, and the corresponding preset dust removal threshold is derived from this real-time speed. This, in turn, determines the preset dust removal threshold for the dust removal system.

[0052] The device runs for a period of time. During the device operation period, the detection device 3 detects the first temperature on the first side of the dustproof net 6 and the second temperature on the second side, and the difference between the first temperature and the second temperature is used to obtain the difference in real-time temperature. The first temperature can be the average of multiple temperatures detected during the operation period, or one of the multiple temperatures detected can be used as the first temperature; the second temperature can be the average of multiple temperatures detected during the operation period, or one of the multiple temperatures detected can be used as the second temperature. The difference between the first temperature and the second temperature is used to obtain the difference in real-time temperature. When the difference in real-time temperature is greater than the preset dust removal threshold, it indicates that the amount of dust accumulated on the dustproof net 6 is large, the dustproof net 6 is seriously clogged, and the amount of dust accumulated has affected the heat dissipation effect of the device. The controller 4 triggers the dust removal function and controls the dust removal device 2 to remove dust.

[0053] Specifically, after the dust removal function is triggered, the controller 4 controls the cooling fan 5 to stop rotating, and at the same time controls the driving member to drive the dust removal member 21 to move relative to the dust screen 6, so that the dust accumulated on the dust screen 6 can fall off; or the controller 4 controls the cooling fan 5 to blow air out of the housing 1, and at the same time controls the driving member to drive the dust removal member 21 to move relative to the dust screen 6. In the process of falling downward, the dust is blown out of the housing 1 through the mesh holes on the dust screen 6 under the action of the airflow, thereby achieving the purpose of dust removal. After the dust removal work is completed, if the real-time temperature difference is less than or equal to the preset dust removal threshold, the controller 4 controls the dust removal device 2 to stop running, and at the same time controls the cooling fan 5 to exhaust air to dissipate heat from the device.

[0054] Furthermore, when the device is operating and the dust removal function is not triggered, the cooling fan 5 is in the first operating state, drawing air from outside the housing 1 into the housing 1 to dissipate heat from the device. The speed of the cooling fan 5 matches the operating conditions of the device. For example, if some components within the device are operating and generating little heat, the cooling fan 5 can be operated at a lower speed to dissipate heat from the device. If multiple components within the device are operating simultaneously and generating a lot of heat, the cooling fan 5 can be operated at a higher speed to dissipate heat from the device. This saves energy while ensuring reliable operation of the device.

[0055] After the dust removal function is triggered, the cooling fan 5 enters the second working state. The cooling fan 5 can blow air out of the housing 1 at the maximum speed to blow the dust out of the housing 1 as it falls downward. The cooling fan 5 can also blow air out of the housing 1 at a certain speed to blow the dust out of the housing 1 as it falls downward. It can be understood that blowing air out of the housing 1 at the maximum speed helps to blow the dust out of the housing 1 to the greatest extent possible as it falls downward.

[0056] In an embodiment of the present invention, the detection device 3 detects the real-time temperatures on the opposite sides of the dustproof net 6 and obtains the difference in real-time temperatures. If the difference in real-time temperatures is greater than a preset dust removal threshold, the controller 4 controls the cooling fan 5 to be in a shutdown or blowing state, and at the same time controls the dust removal device 2 to perform dust removal to remove the dust attached to the dustproof net 6. The controller 4 determines whether the dust removal system has reached the dust removal state based on the relationship between the real-time temperature difference and the preset dust removal threshold, thereby controlling the working state of the dust removal device 2 and the cooling fan 5, and can remove the dust on the dustproof net 6 in a timely and efficient manner.

[0057] like Figure 1 As shown, in an optional embodiment, the detection device 3 includes a first temperature sensor 31 and a second temperature sensor 32 ; the first temperature sensor 31 is arranged on one side of the dustproof net 6 , and the second temperature sensor 32 is arranged on the other side of the dustproof net 6 .

[0058] Specifically, the first temperature sensor 31 is located on the first side of the dustproof screen 6, close to the heat source inside the device, and is used to detect the temperature on the first side of the dustproof screen 6. The first temperature sensor 31 performs temperature detection at regular intervals, thereby obtaining multiple temperature values ​​during the operation of the device. The average of the multiple temperature values ​​can be used as the first temperature, the maximum value of the multiple temperature values ​​can be used as the first temperature, the last detected temperature value can be used as the first temperature, or the first temperature can be obtained by fitting multiple temperature values.

[0059] The second temperature sensor 32 is located on the second side of the dustproof net 6, and is arranged close to the dustproof net 6. The second temperature sensor 32 is used to detect the temperature of the second side of the dustproof net 6. The second temperature sensor 32 performs temperature detection at intervals, thereby obtaining multiple temperature values ​​during the operation period. The average of the multiple temperature values ​​can be used as the second temperature, the maximum value of the multiple temperature values ​​can be used as the second temperature, the last detected temperature value can be used as the second temperature, and the second temperature can be obtained by fitting multiple temperature values.

[0060] The first temperature sensor 31 and the second temperature sensor 32 are both connected to the controller 4, and the controller 4 can obtain the temperature detected by the first temperature sensor 31 and the temperature detected by the second temperature sensor 32. The first temperature is obtained by the temperature detected by the first temperature sensor 31, the second temperature is obtained by the temperature detected by the second temperature sensor 32, and the difference between the first temperature and the second temperature is used to obtain the real-time temperature difference.

[0061] In an embodiment of the present invention, the temperatures on opposite sides of the dustproof net 6 are detected by a first temperature sensor 31 and a second temperature sensor 32. Both the first temperature sensor 31 and the second temperature sensor 32 are connected to a controller 4, and the controller 4 can accurately and conveniently obtain the real-time temperature difference.

[0062] like Figure 1 and Figure 2 As shown, in an optional embodiment, the driving member includes a motor 22 and a linear motion mechanism; the motor 22 is connected to the linear motion mechanism, and the linear motion mechanism is connected to the dust removal member 21. The motor 22 drives the linear motion mechanism to move by forward and reverse rotation, driving the dust removal member 21 to move back and forth relative to the dustproof net 6.

[0063] Specifically, the driving member includes a motor 22 and a linear motion mechanism, which includes a screw 23 and a slider 24. The motor 22 can be a stepper motor and can rotate forward and reverse. The number of motors 22, screws 23, and sliders 24 is set according to actual needs. For example, the number of motors 22, screws 23, and sliders 24 is two, and the two screws 23 are spaced apart along the length of the dustproof net 6. The spacing between the two screws 23 is slightly greater than the length of the dustproof net 6, and the length of the screw 23 is slightly greater than the height of the dustproof net 6. One end of the screw 23 is rotatably connected to the motor 22, and the motor 22 can drive the screw 23 to rotate clockwise or counterclockwise. The slider 24 is slidably connected to the screw 23 and can reciprocate along the length of the screw 23. The dust removal member 21 can be a scraper, a brush, or a roller brush. The dust removal member 21 is rod-shaped, and one end of the dust removal member 21 is connected to one slider 24, and the other end of the dust removal member 21 is connected to the other slider 24.

[0064] like Figure 3 、 Figure 4 and Figure 5 As shown, after the controller 4 triggers the dust removal function, it controls the two motors 22 to rotate forward, and the two sliders 24 drive the dust removal member 21 to move along the height direction of the dust screen 6 from one end of the dust screen 6 to the other end of the dust screen 6. The controller 4 controls the two motors 22 to rotate reversely, and the two sliders 24 drive the dust removal member 21 to move along the height direction of the dust screen 6 from the other end of the dust screen 6 to one end of the dust screen 6. Thus, through the forward and reverse rotation of the motor 22, the two sliders 24 drive the dust removal member 21 to move back and forth relative to the dust screen 6, so that dust on the dust screen 6 falls off.

[0065] In the embodiment of the present invention, through the forward and reverse rotation of the motor 22, the two sliders 24 drive the dust removal member 21 to move back and forth relative to the dustproof net 6, so that the dust accumulated on the dustproof net 6 can be removed conveniently.

[0066] In an optional embodiment, the driving member includes a motor and a crank slider mechanism; the motor is connected to the crank slider mechanism, and the crank slider mechanism is connected to the dust removal member 21. The motor drives the crank slider mechanism to move through unidirectional rotation, driving the dust removal member 21 to move back and forth relative to the dustproof net 6.

[0067] Specifically, the driving member includes a motor and a crank slider mechanism, which includes a crank assembly and a linearly movable slider. The motor and the crank assembly are in driving connection, the crank assembly is connected to the linearly movable slider, and the linearly movable slider is connected to the dust removal member 21. The controller 4 controls the motor to rotate unidirectionally, so that the crank assembly drives the linearly movable slider to reciprocate between one end and the other end of the dustproof net 6. The linearly movable slider drives the dust removal member 21 to reciprocate relative to the dustproof net 6, so that dust on the dustproof net 6 falls off.

[0068] like Figure 6 As shown, an embodiment of the present invention further provides a dust removal method. Based on the above-mentioned dust removal system, the dust removal method includes:

[0069] Step 101: Determine a preset dust removal threshold of a dust removal system;

[0070] Step 102: Obtain the real-time temperature difference between two opposite sides of the dustproof screen 6;

[0071] Step 103: Based on the relationship between the real-time temperature difference and the preset dust removal threshold, the working state of the dust removal device 2 and the working state of the cooling fan 5 are controlled.

[0072] Specifically, the dust removal system, as described above, includes a detection device 3, a dust removal device 2, and a controller 4. The detection device 3, dust removal device 2, and cooling fan 5 are all connected to the controller 4. The dust removal system is part of the overall structure of the device. The device has a housing 1, and the detection device 3, dust removal device 2, cooling fan 5, and controller 4 are all installed in corresponding positions of the housing 1.

[0073] The cooling fan 5 has a first working state and a second working state. In the first working state, the cooling fan 5 can draw cold air outside the equipment into the shell 1 through the dustproof net 6 to dissipate heat from the heat source inside the shell 1; in the second working state, the cooling fan 5 blows air out of the shell 1, and the airflow passes through the dustproof net 6.

[0074] The dust removal device 2 is arranged close to the dustproof net 6. The dust removal device 2 includes a dust removal component 21 and a driving component. The dust removal component 21 is in contact with the dustproof net 6. The dust removal component 21 can move back and forth between one end and the other end of the dustproof net 6 along the height direction to remove dust on the dustproof net 6. The driving component is used to drive the dust removal component 21 to move.

[0075] The detection device 3 includes a first temperature sensor 31 and a second temperature sensor 32 . The first temperature sensor 31 is used to detect the temperature of a first side of the dustproof net 6 , and the second temperature sensor 32 is used to detect the temperature of a second side of the dustproof net 6 .

[0076] During device operation, cooling fan 5 draws air at a certain speed based on the device's operating conditions to dissipate heat. The speed of cooling fan 5 in its current operating state is used as the real-time speed. Cooling fan 5 is connected to controller 4, which can obtain the real-time speed of cooling fan 5 and determine the preset dust removal threshold corresponding to the real-time speed.

[0077] The preset operating time of the device is set, and the device is tested for dust removal status after running for a period of time. When the preset operating time is reached, the temperature detected by the first temperature sensor 31 is used to obtain the first temperature of the first side of the dustproof net 6, and the temperature detected by the second temperature sensor 32 is used to obtain the second temperature of the second side of the dustproof net 6.

[0078] During the preset operating time, the first temperature sensor 31 performs temperature detection at intervals, thereby obtaining multiple temperature values ​​during the preset operating time. The average of the multiple temperature values ​​can be used as the first temperature, the maximum value of the multiple temperature values ​​can be used as the first temperature, or the multiple temperature values ​​can be fitted to obtain the first temperature. Obtaining the first temperature by detecting multiple temperature values ​​can reduce errors in the detection process and ensure the accuracy of the first temperature data.

[0079] During the preset operating time, the second temperature sensor 32 performs temperature detection at intervals, thereby obtaining multiple temperature values ​​during the preset operating time. The average of the multiple temperature values ​​can be used as the second temperature, the maximum value of the multiple temperature values ​​can be used as the second temperature, or the multiple temperature values ​​can be fitted to obtain the second temperature. Obtaining the second temperature by detecting multiple temperature values ​​can reduce errors in the detection process and ensure the accuracy of the second temperature data.

[0080] Determining the real-time temperature difference from the difference between the first and second temperatures facilitates accurate and rapid acquisition of the real-time temperature difference on opposite sides of the dust screen 6. The controller 4 determines whether to trigger the dust removal function based on a comparison between the real-time temperature difference and a preset dust removal threshold. If the real-time temperature difference is less than or equal to the preset dust removal threshold, the dust removal function is not triggered; if the real-time temperature difference is greater than the preset dust removal threshold, the dust removal function is triggered.

[0081] After the dust removal function is triggered, the controller 4 first controls the cooling fan 5 to blow air out of the shell 1 or controls the cooling fan 5 to stop running, and then the controller 4 controls the driving part to drive the dust removal part 21 to move back and forth relative to the dustproof net 6. The dust on the dustproof net 6 is blown to the outside of the shell 1 from the mesh holes on the dustproof net 6 under the action of the airflow during the falling process, thereby achieving the purpose of dust removal.

[0082] After the dust removal work is completed, it is determined that the real-time temperature difference is less than or equal to the preset dust removal threshold, and the controller 4 controls the dust removal device 2 to stop running. At the same time, the controller 4 controls the cooling fan 5 to exhaust air at a preset speed to dissipate heat for the equipment.

[0083] In an embodiment of the present invention, during the operation of the equipment, the temperatures on both sides of the dustproof net 6 are detected by the detection device 3 to obtain the real-time temperature difference, and whether to trigger the dust removal function is determined based on the comparison result of the real-time temperature difference and the preset dust removal threshold. After the dust removal function is triggered, the controller 4 controls the cooling fan 5 to be in a shutdown or blowing state, and at the same time controls the dust removal device 2 to perform dust removal to clean the dust attached to the dustproof net 6. The dust on the dustproof net 6 can be removed in a timely and efficient manner to ensure the reliable operation of the equipment.

[0084] In an optional embodiment, the step of determining a preset dust removal threshold of the dust removal system includes:

[0085] The real-time speed of the cooling fan 5 is obtained; based on the real-time speed, and the relationship between the cooling fan speed and the dust-free temperature difference of the dustproof net, a preset dust removal threshold is determined.

[0086] In an optional embodiment, before determining the preset dust removal threshold of the dust removal system, the method further includes:

[0087] When the dustproof net 6 is free of dust, the cooling fan 5 is controlled to run at multiple speeds in sequence, and multiple dust-free temperature differences on opposite sides of the dustproof net 6 are obtained, where the multiple dust-free temperature differences correspond to the multiple speeds.

[0088] Based on multiple dust-free temperature differences and multiple rotation speeds, a relationship between the cooling fan rotation speed and the dust-free temperature difference of the dust filter is fitted.

[0089] Specifically, the rotation speed of the cooling fan 5 can be divided into percentages, with an interval of 5% to divide a section, or an interval of 10% to divide a section, thereby dividing it into multiple speed sections, each speed section selects a speed, and thus ten speed sections correspond to ten different speeds. The ten different speeds are defined as the first speed, the second speed, the third speed... and the tenth speed, respectively. Taking the first speed as an example, the first dust-free temperature difference corresponding to the first speed is tested. Before the test, ensure that the dustproof net 6 is in a clean state, that is, there is no dust adhered to the dustproof net 6, start the test, the equipment is in working state, the cooling fan 5 draws air at the first speed, and the temperature of the first side of the dustproof net 6 and the temperature of the second side of the dustproof net 6 are detected by the first temperature sensor 31 and the second temperature sensor 32.

[0090] During a preset operating time, the first temperature sensor 31 performs temperature detection at regular intervals to obtain multiple temperature values, from which a first temperature is obtained. The second temperature sensor 32 performs temperature detection at regular intervals to obtain multiple temperature values, from which a second temperature is obtained. The difference between the first and second temperatures is used to obtain a first dust-free temperature difference corresponding to the first rotational speed.

[0091] By analogy, a test is performed for each rotational speed, thereby obtaining a first dust-free temperature difference corresponding to the first rotational speed, a second dust-free temperature difference corresponding to the second rotational speed, a third dust-free temperature difference corresponding to the third rotational speed... and a tenth dust-free temperature difference corresponding to the tenth rotational speed.

[0092] By fitting the data for ten speeds and the corresponding ten dust-free temperature differences, we obtain a relationship between the speed of the cooling fan 5 and the dust-free temperature difference on opposite sides of the dust screen 6. By adding a weight to the dust-free temperature difference, we can determine the dust removal threshold. The dust removal threshold ranges from 4 to 6. It is understood that the higher the speed of the cooling fan 5, the lower the dust removal threshold. It is also understood that multiple different speeds can be tested, with multiple speeds corresponding to multiple dust-free temperature differences.

[0093] The controller 4 stores a relationship between the rotation speed of the cooling fan 5 and the dust-free temperature difference on the opposite sides of the dustproof net 6. During the operation of the equipment, the controller 4 obtains the real-time rotation speed of the cooling fan 5, substitutes the real-time rotation speed into the relationship formula, obtains the dust-free temperature difference, and further obtains the dust removal threshold through the weighted number. The dust removal threshold corresponding to the real-time rotation speed is obtained from the real-time rotation speed. This dust removal threshold is the preset dust removal threshold of the dust removal system.

[0094] In an optional embodiment, based on the relationship between the real-time temperature difference and the preset dust removal threshold, controlling the working state of the dust removal device 2 and the working state of the cooling fan 5 specifically includes:

[0095] When the real-time temperature difference is greater than the preset dust removal threshold, the cooling fan 5 is controlled to blow air toward the outside of the dustproof net 6 , and the dust removal device 2 is controlled to clean the dust on the dustproof net 6 .

[0096] Specifically, when the preset operating time is reached and the real-time temperature difference is determined to be greater than the preset dust removal threshold, controller 4 first controls cooling fan 5 to blow air toward the outside of dust screen 6 at a target speed, the target speed being not specifically limited. Simultaneously, controller 4 controls motor 22 to start, and two sliders 24 drive dust removal element 21 to reciprocate relative to dust screen 6. Dust on dust screen 6 is blown out of housing 1 by the airflow as it falls.

[0097] When the preset operating time is reached, it is determined that the difference in real-time temperature is less than or equal to the preset dust removal threshold, and the controller 4 controls the cooling fan 5 to continue to draw air at a preset speed to dissipate heat for the device.

[0098] In an optional embodiment, controlling the cooling fan 5 to blow air toward the outside of the dustproof net 6 and controlling the dust removal device 2 to clean dust on the dustproof net 6 specifically includes:

[0099] The cooling fan 5 is controlled to blow air at the maximum speed, and the dust removal device 2 is controlled to remove dust for a preset time.

[0100] Specifically, after the dust removal function is triggered, the controller 4 controls the cooling fan 5 to blow air out of the housing 1 at a target speed. The cooling fan 5 has multiple speeds. The cooling fan 5 can blow air out of the housing 1 at the maximum speed to blow dust out of the housing 1 as it falls. The cooling fan 5 can also blow air out of the housing 1 at a certain speed to blow dust out of the housing 1 as it falls downward. It is understood that blowing air out of the housing 1 at the maximum speed helps to maximize the amount of dust that falls out of the housing 1.

[0101] After the dust removal function is triggered, the controller 4 controls the dust removal device 2 to perform dust removal according to preset parameters. The preset parameters include preset duration and preset speed, etc. The preset duration is the duration of the dust removal device 2 performing a dust removal operation, and the preset speed is the operating speed of the motor 22, that is, the moving speed of the dust removal component 21. For example, within the preset duration of the dust removal device 2 working, the detection device 3 detects the first temperature on the first side of the dustproof net 6 and the second temperature on the second side of the dustproof net 6 within the preset duration. When the preset duration is reached, the controller 4 obtains the real-time temperature difference based on the difference between the first temperature and the second temperature. The controller 4 further determines whether to continue dust removal based on the comparison result of the real-time temperature difference and the preset dust removal threshold. If it is determined that the real-time temperature difference is greater than the preset dust removal threshold, the control value controls the dust removal device 2 to continue operating until the real-time temperature difference is less than or equal to the preset dust removal threshold. The controller 4 controls the dust removal device 2 to stop running, and at the same time, the controller 4 controls the cooling fan 5 to exhaust air at a preset speed to dissipate heat from the equipment.

[0102] Furthermore, after the controller 4 controls the dust removal device 2 to run for a preset time, the dust on the dustproof net 6 is partially or completely removed, and the difference in real-time temperature on both sides of the dustproof net 6 will change.

[0103] During the preset operation time of the dust removal device 2, the first temperature sensor 31 and the second temperature sensor 32 continue to detect the temperatures on opposite sides of the dustproof net 6. The first temperature sensor 31 performs temperature detection at intervals, thereby obtaining multiple temperature values ​​within the preset time. The average value of the multiple temperature values ​​can be used as the updated first temperature, the maximum value of the multiple temperature values ​​can be used as the updated first temperature, or the multiple temperature values ​​can be fitted to obtain the updated first temperature.

[0104] The second temperature sensor 32 performs temperature detection at regular intervals, thereby obtaining multiple temperature values ​​within a preset time period. The average value of the multiple temperature values ​​can be used as the updated second temperature, the maximum value of the multiple temperature values ​​can be used as the updated second temperature, or the multiple temperature values ​​can be fitted to obtain the updated second temperature.

[0105] After dust removal device 2 has operated for a preset period of time, the difference between the updated first temperature and the updated second temperature is used to obtain an updated real-time temperature difference. Controller 4 then compares this updated real-time temperature difference with a preset dust removal threshold. If the updated real-time temperature difference is greater than the preset dust removal threshold, controller 4 controls dust removal device 2 to continue operating for a preset period of time. Until the next updated real-time temperature difference is less than or equal to the preset dust removal threshold, controller 4 controls dust removal device 2 to cease operation. Simultaneously, controller 4 controls cooling fan 5 to exhaust air at a preset speed to dissipate heat from the device.
