[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] One of the core concepts of the embodiment of the present invention is to detect the wind speed of the fan in real time through an anemometer, determine the dirtiness and blockage condition of the filter according to the wind speed, and control the cleaning component to clean the filter according to the dirtiness and blockage condition of the filter to maintain the cleaning effect of the filter, reduce the frequency of user cleaning and replacement of the filter, and improve the convenience of use and user experience.

[0047] Reference Figure 1 , shows a structural block diagram of a fan provided by an embodiment of the present invention.

[0048] The fan 11 includes: a filter 101, which is arranged at the air inlet of the fan 11 and is used to filter impurities in the air; an anemometer 102, which is arranged at the air outlet of the fan 11 and is used to detect wind speed; a cleaning component 103, including a cleaning brush 1031; the cleaning brush is arranged relative to the filter 101 and is used to clean the filter 101; a main control board 104, which is used to obtain the wind speed detected by the anemometer 102; determine the dirtiness or blockage of the filter 101 according to the wind speed; and control the operation of the cleaning component 103 according to the dirtiness or blockage of the filter 101 to clean the filter 101.

[0049] In order to ensure that the air inhaled by the fan is clean and pollution-free, thereby improving the service life and performance of the fan 11. The filter 101 is set at the air inlet of the fan 11 to filter impurities in the air and improve the service life and performance of the fan. Impurities in the air, such as dust, pollen, bacteria, etc., if they enter the fan 11 directly without being filtered, may cause wear and blockage of fan blades, motors and other components, affecting the normal operation and heat dissipation effect of the fan 11. Specifically, the filter 101 intercepts large particles of impurities in the air on the surface of the filter by physical filtration to prevent them from entering the fan. The material and structural design of the filter can be selected according to different use environments and needs. For example, the HEPA filter can effectively filter tiny particles, and the activated carbon filter can absorb odors and harmful gases. In addition, the filter can also reduce the maintenance and cleaning frequency of the fan 11, reducing the cost of use and the difficulty of maintenance.

[0050] The material of the filter 101 can be made of activated carbon particles or activated carbon fibers, which can absorb odors and harmful gases, such as formaldehyde, benzene, etc., to improve the freshness of the air; it can be made of electrostatic fiber materials, which can effectively capture tiny particles in the air through the principle of electrostatic adsorption; it can be composed of a variety of filter materials, integrating multiple filtering functions, which can not only filter tiny particles, but also absorb odors and harmful gases, thereby improving the air purification effect; it can also be made of nano materials, such as nano silver, nano titanium dioxide, etc., which have antibacterial, antiviral, and harmful gas decomposition functions, thereby improving the cleanliness and safety of the air.

[0051] The anemometer 102 can provide real-time wind speed data by measuring the wind speed at the fan outlet of the fan 11, helping the user understand the working status of the fan 11. These data can be used to adjust the operating mode of the fan, such as automatically adjusting the wind speed, switching the wind speed gear, etc., to meet different usage requirements. In addition, the anemometer can also be used for performance testing and fault diagnosis of the fan, timely discovering and solving problems in the operation of the fan, and improving the reliability and service life of the fan. Common anemometers include: hot wire anemometers, impeller anemometers, ultrasonic anemometers, pitot tube anemometers and laser Doppler anemometers. The hot wire anemometer determines the wind speed by measuring the temperature change of the hot wire, which is suitable for low wind speed measurement. The impeller anemometer measures the wind speed by the rotation speed of the impeller, which is suitable for medium and high wind speed measurement. The ultrasonic anemometer uses the change in the propagation speed of ultrasonic waves in the air to measure the wind speed, which is suitable for high-precision measurement. The pitot tube anemometer determines the wind speed by measuring the air pressure difference, which is suitable for high wind speed measurement. Laser Doppler anemometer uses the laser Doppler effect to measure wind speed and is suitable for high-precision, non-contact measurement.

[0052] The main control board 104 can monitor the operating status of the fan 11 in real time by acquiring the wind speed data detected by the anemometer 102. When the wind speed is lower than the preset value, the main control board 104 will determine that the filter may be dirty and blocked, and trigger the cleaning component to perform a cleaning operation. The cleaning component includes a cleaning brush, which removes impurities on the surface of the filter by physical brushing to restore the filtering capacity of the filter. The design of the cleaning brush can be optimized according to the material and structure of the filter, such as using soft bristles to avoid damage to the filter.

[0053] The main control board can also automatically adjust the operating frequency and cleaning intensity of the cleaning component according to the dirtiness and blockage of the filter, ensuring that the filter always maintains a good filtering effect. In addition, the main control board can also record the cleaning history and operating data of the filter, provide users with detailed maintenance suggestions and fault diagnosis, and improve the reliability and service life of the fan 11. Through the intelligent control of the main control board, the cleanliness and filtering effect of the filter can be effectively maintained, the service life of the filter can be extended, and the operating efficiency and air purification effect of the fan 11 can be improved. This design not only improves the practicality and reliability of the fan 11, but also optimizes the filter cleaning effect and maximizes cost-effectiveness.

[0054] Reference Figure 2 , shows a structural block diagram of another fan provided by an embodiment of the present invention.

[0055] Reference Figure 3 , shows a structural block diagram of another fan provided by an embodiment of the present invention.

[0056] The blade 105 is one of the core components of the fan 11 and is responsible for generating airflow. The fan 1 also includes another motor that controls the rotation of the fan to drive the blades to rotate. When rotating, the blades cut the air and exert force to make the air flow from one side to the other, thereby forming a continuous airflow. The design of the blades (such as shape, angle, number) directly affects the air volume and air pressure of the fan 11. The optimized blade structure can improve the air flow efficiency, reduce noise, and ensure that the fan 11 can operate stably under various working conditions.

[0057] The front net 106 and the rear net 107 are respectively located at the air inlet and the air outlet of the fan 11, and play a role of protection and filtering. The front net 106 mainly prevents larger foreign objects from entering the fan to avoid damaging the blades and other internal components. The rear net 107 is mainly used to protect the user from being hurt by the high-speed rotating blades, and also plays a certain role in guiding the air to ensure smooth discharge of the airflow. In addition, the design of the front and rear nets also takes into account aesthetics and aerodynamic performance to reduce airflow resistance and improve overall efficiency.

[0058] The interactive component 108 is an interface between the user and the fan 11, and usually includes physical buttons, a touch screen or a remote control module. It allows the user to easily set and adjust various parameters of the fan 1, such as wind speed, mode (natural wind, sleep wind, etc.), timer switch, etc. Modern interactive components may also integrate intelligent control systems, support voice control, mobile phone App remote operation and other functions, and further enhance the user experience. Through the interactive component, the user can easily manage the operating status of the fan 11 to meet the needs of different scenarios. In addition, in addition to the interactive component, the user can also control the fan 11 through a remote control.

[0059] The cleaning assembly 103 includes a cleaning brush 1031 for cleaning the filter 101. The cleaning brush 1031 is arranged relative to the filter to ensure that it can directly contact and effectively clean the surface of the filter. The operation of the cleaning brush is controlled by the motor 1032, which drives the cleaning brush to rotate to remove dust and dirt on the filter. Through the intelligent automatic cleaning mechanism, the system can monitor the dirtiness and blockage of the filter in real time, and once blockage is detected, the cleaning brush is immediately triggered to clean. This design not only extends the service life of the filter and reduces the frequency of manual cleaning and replacement of the filter by users, but also improves the overall reliability and performance of the equipment, ensuring that the fan 11 is always in the best working condition.

[0060] In one embodiment, the fan 11 further includes blades 105 and a rear net 107 ; the filter 101 is annular and is disposed between the blades 105 and the rear net 107 .

[0061] The blade 105 is the core component of the fan 11. It generates airflow by rotating, sucking air from the air inlet and exhausting it from the air outlet. The rear net 107 protects the blades and prevents foreign matter from entering the fan. The filter 101 is annular and is arranged between the blade 105 and the rear net 107. It can effectively intercept impurities in the air, such as dust, pollen, bacteria, etc., to prevent them from entering the fan 11 and affecting the normal operation and heat dissipation effect of the fan 11. The design of the annular filter can maximize the filtering area, improve the filtering efficiency, and ensure the smoothness of air circulation.

[0062] In one embodiment, the cleaning component 103 includes a motor 1032 connected to the cleaning brush 1031 , and is used to drive the cleaning brush 1031 to rotate around the center point of the filter 101 .

[0063] By driving the cleaning brush 1031 to rotate around the center point of the filter through the motor 1032, the system can automatically detect and respond to the dirty and blocked condition of the filter. When the anemometer detects a drop in wind speed, indicating that the filter may be blocked, the motor 1032 starts immediately, driving the cleaning brush 1031 to perform all-round cleaning. This intelligent automatic cleaning mechanism reduces the frequency of manual cleaning and replacement of the filter by users, improving the convenience of use and user experience. At the same time, the design of the cleaning brush 1031 rotating around the center point of the filter ensures that it can cover the entire surface of the filter without leaving any dead corners. Compared with the fixed position cleaning method, the rotating cleaning brush can remove dust and dirt on the filter more evenly, maintain the permeability of the filter, and thus maintain the efficient airflow output of the fan 11. In addition, the material and structure of the cleaning brush have been optimized to effectively remove dirt without damaging the filter.

[0064] Finally, the design of the cleaning brush 1031 rotating around the center point of the filter ensures that it can cover the entire surface of the filter without leaving any dead corners. Compared with the fixed position cleaning method, the rotating cleaning brush can more evenly remove dust and dirt on the filter, maintain the permeability of the filter, and thus maintain the efficient airflow output of the fan 11. In addition, the material and structure of the cleaning brush have been optimized to effectively remove dirt without damaging the filter. At the same time, the low noise and high efficiency characteristics of the motor 1032 also ensure that the cleaning operation will not interfere with the user's daily life or work environment.

[0065] In one embodiment, the main control board 104 is used to determine that the filter 101 is in good condition when the wind speed is greater than or equal to a first wind speed threshold; to determine that the filter 101 is in normal condition when the wind speed is less than the first wind speed threshold and greater than or equal to a second wind speed threshold; the first wind speed threshold is greater than the second wind speed threshold; when the wind speed is less than the second wind speed threshold, the filter 101 is in severe condition; and when the filter 101 is in severe condition, control the cleaning component to operate to clean the filter.

[0066] The first wind speed threshold can be 80% of the wind speed when the filter 101 is cleaned and there is no dirt or blockage, and the second wind speed threshold can be 50% of the wind speed when the filter 101 is cleaned and there is no dirt or blockage. These two thresholds provide clear standards for distinguishing different dirt and blockage conditions of the filter, thereby achieving precise control and response. When the wind speed is greater than or equal to the first wind speed threshold (80%), it indicates that the filter is in good condition, that is, the filter is basically kept clean and no immediate cleaning operation is required. When the wind speed is less than the first wind speed threshold (80%), but greater than or equal to the second wind speed threshold (50%), it indicates that the filter is generally dirty and blocked, that is, the filter begins to be dirty and blocked to a certain extent, but has not yet reached the level that requires emergency cleaning. When the wind speed is less than the second wind speed threshold (50%), it indicates that the filter is seriously dirty and blocked, that is, the filter has been significantly blocked, seriously affecting the normal circulation of the airflow, and must be cleaned immediately.

[0067] Once the main control board 104 determines that the filter is "serious", it will immediately trigger the cleaning component 103 to perform automatic cleaning. The cleaning component includes a cleaning brush 1031 driven by a motor 1032, which rotates around the center point of the filter to fully cover and remove dust and dirt on the filter. This intelligent automatic cleaning mechanism not only improves the cleaning efficiency, but also extends the service life of the filter, and reduces the frequency of manual cleaning and replacement of the filter by users. Through precise wind speed monitoring and intelligent dirty blockage assessment, the main control board 104 can promptly detect and deal with the problem of dirty filter blockage, ensuring that the fan 11 is always in an efficient operating state. This not only improves the user experience, but also reduces maintenance costs and improves the overall reliability and performance of the equipment. Users do not need to pay attention to the status of the filter frequently. The system can automatically complete the necessary cleaning operations to maintain the best state of smooth air circulation.

[0068] In one embodiment, the main control board 104 is further used to output reminder information according to the dirtiness or blockage of the filter 101 .

[0069] When the main control board 104 determines that the filter is dirty and blocked as "normal", it can output a mild reminder message to prompt the user to pay attention to the status of the filter. This reminder makes the user aware that the filter has begun to become dirty and blocked to a certain extent. Although it has not reached the level that requires emergency cleaning, it is still recommended to pay attention regularly to prevent the problem from worsening. This helps users to perform simple maintenance at an early stage and extend the service life of the filter. When the filter is dirty and blocked as "serious", the main control board will issue a more obvious reminder message to inform the user that the cleaning operation must be performed immediately. This instant feedback not only improves the user's experience, but also avoids performance degradation and increased energy consumption caused by filter blockage. In addition, after the automatic cleaning is completed, the system can also output a confirmation message to inform the user that the cleaning is completed, which enhances the user's trust and satisfaction with the device. By outputting reminder information, the main control board 104 can help users prevent potential problems. For example, if the filter is not cleaned for a long time, it may cause reduced fan efficiency, increased noise, and even damage to internal components. Timely reminders can prompt users to take action to keep the device in optimal operating condition and reduce maintenance costs and downtime.

[0070] In one embodiment, the fan 11 has a display light;

[0071] The main control board 104 is used to control the display light to display a first color when the filter 101 is in a good condition of being blocked; to control the display light to display a second color when the filter 101 is in a moderate condition of being blocked; and to control the display light to display a third color when the filter 101 is in a serious condition of being blocked.

[0072] The display light of the fan 11 can be set in multiple positions according to design requirements and user experience optimization, and each position has its specific advantages and functions. The display light can be located on the front panel or front net of the fan, which is one of the most common locations. This design allows the user to directly view the status of the fan, such as wind speed, mode, filter dirtiness, etc. when in use. The display light on the front panel is usually integrated with interactive components (such as buttons or touch screens) to provide intuitive and easy-to-understand visual feedback. In addition, this position makes it easy for users to obtain information when operating at close range, which is particularly suitable for smart fans.

[0073] The indicator light can also be set on the top edge or side of the fan. This layout is not only beautiful, but also ensures that users can easily observe the fan status from different angles, especially suitable for standing fans placed at a higher position. The indicator light on the top or side does not interfere with the airflow, while providing good visibility, especially at a long distance or indirect viewing angle. It is also a common choice to set the indicator light near the control panel or integrate it directly on the control panel. This design allows the indicator light to be closely integrated with the control button or touch screen, and the user can see the current settings and operating status at a glance during operation. For example, when the user adjusts the fan speed or switches the mode, the indicator light can reflect these changes in real time and provide instant feedback. The indicator light can also surround the fan's air outlet to form a ring of lights. This design is not only beautiful, but also can indicate the different working states of the fan through different colors or flashing modes. For example, green indicates normal operation, and red indicates that the filter needs to be cleaned or there is a fault. The ring indicator light not only enhances the visual effect, but also attracts the user's attention, ensuring that important information is not overlooked.

[0074] The first color may be green, the second color may be yellow, and the third color may be red. When the main control board 104 determines that the filter 101 is "good", it controls the display light to display green. Green usually symbolizes safety and normal status, indicating that the filter is basically kept clean and the airflow is unobstructed. In this case, the user does not need to take any additional maintenance measures and can use the fan with confidence. The continuous display of the green light makes the user feel at ease and enhances their trust in the device. In addition, the green light can also be used as the default state for daily use to remind the user that the device is in the best working condition.

[0075] When the filter is judged to be "normal", the main control board 104 controls the display light to display yellow. Yellow is a warning color, which reminds the user that the filter has begun to become dirty and clogged to a certain extent. Although it has not yet reached the level that requires emergency cleaning, it is still recommended to pay attention to it regularly. This color coding serves as an early warning, reminding the user to perform simple maintenance at a convenient time, such as manual cleaning or checking the filter status. The yellow light not only increases the user's alertness, but also helps the user take preventive measures before the problem worsens, extending the service life of the filter and avoiding unnecessary performance degradation.

[0076] When the filter is judged to be "serious", the main control board 104 controls the display light to display red. Red is a typical warning color, indicating that the filter is significantly blocked, seriously affecting the normal flow of air, and must be cleaned immediately. This strong visual warning can quickly attract the attention of users, prompting them to take action to start the automatic cleaning component or manually clean the filter. The red light not only improves the user's response speed, but also prevents performance degradation, noise increase, and even equipment damage caused by long-term blockage.

[0077] By combining the filter dirtiness and blockage conditions with display lights of different colors, the main control board 104 realizes real-time monitoring and intelligent feedback of the filter status. This design allows users to quickly understand the filter status by observing the color of the display light without having to view complex instruments or data. The color change of the display light provides instant visual feedback, helping users to find problems and take corresponding measures at the first time, significantly enhancing the convenience and efficiency of equipment management. The three colors of green, yellow and red correspond to different levels of dirtiness and blockage of the filter. Green means that the filter is in good condition and the user can use it with confidence; yellow means that the filter begins to become dirty and blocked to a certain extent, and it is recommended that the user pay attention and transmit a cleaning signal to the fan; red warns that the filter is seriously dirty and blocked and must be cleaned immediately. This color coding mechanism is very intuitive. Users do not need to understand complex technical indicators and can know the status of the filter at a glance, which greatly simplifies the operation process.

[0078] In one embodiment, the fan 11 includes an interactive component 108;

[0079] The main control panel 104 is used to control the operation of the cleaning component 103 to clean the filter 101 when the user triggers the cleaning function of the filter 101 through the interactive component 108 .

[0080] The interactive component 108 provides a user-friendly interface, which can be a physical button, a touch screen, or a remote control device (such as a mobile phone application). The user can easily trigger the filter cleaning function by simply pressing a button or clicking the screen, without complicated settings or manually removing the filter for cleaning. This method greatly simplifies the operation process, especially for users who are not familiar with technology, providing great convenience.

[0081] When the user triggers the cleaning function through the interactive component 108, the main control board 104 immediately receives the instruction and starts the cleaning component 103. This real-time response mechanism ensures that the user's needs are met in a timely manner, avoiding the reduction of air volume and increase of energy consumption due to dirty filter blockage. The main control board 104 accurately controls the working time and intensity of the cleaning component to ensure that each cleaning can be completed efficiently without causing unnecessary interference to the user.

[0082] In one embodiment, the main control panel 104 is also used to control the blades 105 to stop rotating when the filter 101 is being cleaned.

[0083] The rotation of blades 105 will generate a strong airflow, which may not only blow away the dust just brushed up by the cleaning brush 1031, resulting in incomplete cleaning, but may also cause the dust to re-attach to the filter. By controlling the blades 105 to stop rotating, this airflow interference can be eliminated, ensuring that the cleaning brush can more effectively contact and remove dirt on the filter, thereby improving cleaning efficiency and quality. During the cleaning process, if the blades 105 continue to rotate, it may cause physical damage to the cleaning components or the filter itself, and even pose a safety hazard. For example, a blade rotating at high speed may collide or rub against the cleaning brush, causing equipment damage or failure. Stopping the blades from rotating can avoid these potential risks and ensure the safety and reliability of the cleaning process.

[0084] When the blade 105 stops rotating, the overall load of the fan system is reduced, reducing the working pressure of each component in the fan 11. This not only helps to extend the service life of the motor and other key components, but also ensures that the cleaning component 103 operates in a stable working environment, further improving the cleaning effect and the reliability of the system. In addition, by controlling the blade 105 to stop rotating, the user can obtain a quieter and smoother operating environment during the cleaning process. After the cleaning is completed, the system can restore the normal operation of the blades to provide continuous and stable air circulation and cooling effects. This design not only improves user satisfaction, but also enhances the trust and dependence on the equipment.

[0085] An embodiment of the present invention provides a fan, which includes: a filter, which is arranged at the air inlet of the fan and is used to filter impurities in the air; an anemometer, which is arranged at the air outlet of the fan and is used to detect wind speed; a cleaning component, which includes a cleaning brush; the cleaning brush is arranged relative to the filter and is used to clean the filter; a main control board, which is used to obtain the wind speed detected by the anemometer; determine the filter dirtiness and blockage according to the wind speed; and control the operation of the cleaning component according to the filter dirtiness and blockage to clean the filter. The embodiment of the present invention detects the wind speed of the fan in real time through the anemometer, determines the filter dirtiness and blockage according to the wind speed, and controls the cleaning component to clean the filter according to the filter dirtiness and blockage, so as to maintain the cleaning effect of the filter, reduce the frequency of users cleaning and replacing the filter, and improve the convenience of use and user experience.

[0086] Reference Figure 3 , shows the step flow of a fan filter cleaning method provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0087] Step 301, obtaining the wind speed detected by the anemometer;

[0088] By obtaining the wind speed data detected by the anemometer, the operating status of the fan can be monitored in real time. When the wind speed is lower than the preset value, the main control board will determine that the filter may be dirty and clogged, and trigger the cleaning component to perform a cleaning operation.

[0089] Step 302, determining the filter screen dirtiness and blockage condition according to the wind speed;

[0090] It can record the filter's cleaning history and operating data, provide users with detailed maintenance suggestions and fault diagnosis, and improve the reliability and service life of the fan. Through the intelligent control of the main control board, the cleanliness and filtering effect of the filter can be effectively maintained, the service life of the filter can be extended, and the operating efficiency and air purification effect of the fan can be improved. This design not only improves the practicality and reliability of the fan, but also optimizes the filter cleaning effect and maximizes cost-effectiveness.

[0091] Step 303: Control the operation of the cleaning component according to the dirtiness or blockage of the filter to clean the filter.

[0092] The cleaning component is controlled according to the filter blockage to ensure efficient operation of the fan system and optimize the user experience. By intelligently evaluating the degree of filter blockage and starting the cleaning function at the right time, the filter life can be extended and the performance degradation and energy consumption increase caused by filter blockage can be avoided.

[0093] In one embodiment, determining the filter screen dirtiness and blockage condition according to the wind speed includes:

[0094] When the wind speed is greater than or equal to the first wind speed threshold, it is determined that the filter screen is in good condition;

[0095] When the wind speed is less than the first wind speed threshold and greater than or equal to the second wind speed threshold, it is determined that the filter is generally dirty and blocked; the first wind speed threshold is greater than the second wind speed threshold;

[0096] When the wind speed is less than the second wind speed threshold, it is determined that the filter is seriously blocked;

[0097] The controlling the operation of the cleaning component according to the dirty or blocked condition of the filter screen to clean the filter screen comprises:

[0098] When the filter is seriously clogged, the cleaning component is controlled to run to clean the filter.

[0099] The first wind speed threshold can be 80% of the wind speed when the filter is cleaned and there is no dirt or blockage, and the second wind speed threshold can be 50% of the wind speed when the filter is cleaned and there is no dirt or blockage. These two thresholds provide clear standards for distinguishing different dirt and blockage conditions of the filter, thereby achieving precise control and response. When the wind speed is greater than or equal to the first wind speed threshold (80%), it indicates that the filter is in good condition, that is, the filter is basically kept clean and no immediate cleaning operation is required. When the wind speed is less than the first wind speed threshold (80%), but greater than or equal to the second wind speed threshold (50%), it indicates that the filter is generally dirty and blocked, that is, the filter begins to be dirty and blocked to a certain extent, but has not yet reached the level that requires emergency cleaning. When the wind speed is less than the second wind speed threshold (50%), it indicates that the filter is seriously dirty and blocked, that is, the filter has been significantly blocked, seriously affecting the normal circulation of the airflow, and must be cleaned immediately.

[0100] Once the main control board determines that the filter is "severely" dirty, it will immediately trigger the cleaning component to automatically clean it. The cleaning component includes a cleaning brush driven by a motor, which rotates around the center point of the filter to fully cover and remove dust and dirt on the filter. This intelligent automatic cleaning mechanism not only improves cleaning efficiency, but also extends the service life of the filter, reducing the frequency of manual cleaning and replacement of the filter by users. Through precise wind speed monitoring and intelligent dirty blockage assessment, the main control board can promptly detect and deal with filter dirty blockage problems to ensure that the fan is always in an efficient operating state. This not only improves the user experience, but also reduces maintenance costs and improves the overall reliability and performance of the equipment. Users do not need to pay attention to the filter status frequently. The system can automatically complete the necessary cleaning operations to maintain the best state of unobstructed air circulation.

[0101] In one embodiment, the method further comprises:

[0102] Output a reminder message according to the filter screen dirtiness and blockage condition.

[0103] When the main control board determines that the filter is dirty and clogged as "normal", it can output a mild reminder message to prompt the user to pay attention to the status of the filter. This reminder makes the user aware that the filter has begun to become dirty and clogged to a certain extent. Although it has not yet reached the level that requires urgent cleaning, it is still recommended to pay attention regularly to prevent the problem from worsening. This helps users perform simple maintenance at an early stage and extend the service life of the filter. When the filter is dirty and clogged as "serious", the main control board will issue a more obvious reminder message to inform the user that the cleaning operation must be performed immediately. This immediate feedback not only improves the user's experience, but also avoids the performance degradation and increased energy consumption caused by filter clogging. In addition, after the automatic cleaning is completed, the system can also output a confirmation message to inform the user that the cleaning is completed, which enhances the user's trust and satisfaction with the device. By outputting reminder messages, the main control board can help users prevent potential problems. For example, if the filter is not cleaned for a long time, it may cause reduced fan efficiency, increased noise, and even damage to internal components. Timely reminders can prompt users to take action to keep the device in optimal operating condition and reduce maintenance costs and downtime.

[0104] In one embodiment, outputting reminder information according to the filter screen being dirty or blocked includes:

[0105] When the filter is in good condition, the display light is controlled to display a first color; when the filter is in moderate condition, the display light is controlled to display a second color; when the filter is in severe condition, the display light is controlled to display a third color.

[0106] The fan can remind the user of the dirty or blocked condition through the display light. The display light can be set in multiple positions according to design requirements and user experience optimization, and each position has its specific advantages and functions. The display light can be located on the front panel or front net of the fan, which is one of the most common locations. This design allows the user to directly view the status of the fan, such as wind speed, mode, filter dirty or blocked condition, etc. when using it. The display light on the front panel is usually integrated with interactive components (such as buttons or touch screens) to provide intuitive and easy-to-understand visual feedback. In addition, this position makes it easy for users to obtain information when operating at close range, which is especially suitable for smart fans.

[0107] The indicator light can also be set on the top edge or side of the fan. This layout is not only beautiful, but also ensures that users can easily observe the fan status from different angles, especially suitable for standing fans placed at a higher position. The indicator light on the top or side does not interfere with the airflow, while providing good visibility, especially at a long distance or indirect viewing angle. It is also a common choice to set the indicator light near the control panel or integrate it directly on the control panel. This design allows the indicator light to be closely integrated with the control button or touch screen, and the user can see the current settings and operating status at a glance during operation. For example, when the user adjusts the fan speed or switches the mode, the indicator light can reflect these changes in real time and provide instant feedback. The indicator light can also surround the fan's air outlet to form a ring of lights. This design is not only beautiful, but also can indicate the different working states of the fan through different colors or flashing modes. For example, green indicates normal operation, and red indicates that the filter needs to be cleaned or there is a fault. The ring indicator light not only enhances the visual effect, but also attracts the user's attention, ensuring that important information is not overlooked.

[0108] The first color can be green; the second color can be yellow; and the third color can be red. When the main control board determines that the filter is "good", it controls the display light to show green. Green usually symbolizes safety and normal status, indicating that the filter is basically clean and the airflow is unobstructed. In this case, the user does not need to take any additional maintenance measures and can use the fan with confidence. The continuous display of green light makes users feel at ease and enhances their trust in the device. In addition, the green light can also be used as the default state for daily use to remind users that the device is in optimal working condition.

[0109] When the filter is judged to be "normal", the main control panel control display light shows yellow. Yellow is a warning color, reminding users that the filter has begun to become dirty and clogged to a certain extent. Although it has not yet reached the level that requires emergency cleaning, it is still recommended to pay attention to it regularly. This color coding serves as an early warning, reminding users to perform simple maintenance at their convenience, such as manual cleaning or checking the filter status. The yellow light not only increases user alertness, but also helps users take preventive measures before the problem worsens, extending the service life of the filter and avoiding unnecessary performance degradation.

[0110] When the filter is judged to be "serious", the main control panel control display light turns red. Red is a typical warning color, indicating that the filter is significantly blocked, seriously affecting the normal flow of air, and must be cleaned immediately. This strong visual warning can quickly attract the user's attention, prompting them to take action to start the automatic cleaning component or manually clean the filter. The red light not only improves the user's response speed, but also prevents performance degradation, increased noise and even equipment damage caused by long-term blockage.

[0111] In one embodiment, the method further comprises:

[0112] When the user triggers the filter cleaning function through the interactive component, the cleaning component is controlled to run to clean the filter.

[0113] The interactive component provides a user-friendly interface, which can be a physical button, a touch screen, or a remote control device (such as a mobile phone application). Users can easily trigger the filter cleaning function by simply pressing a button or clicking the screen, without complicated settings or manually removing the filter for cleaning. This method greatly simplifies the operation process, especially for users who are not familiar with technology, providing great convenience. When the user triggers the cleaning function through the interactive component, the main control board immediately receives the instruction and starts the cleaning component. This real-time response mechanism ensures that the user's needs are met in a timely manner and avoids the decrease in air volume and increase in energy consumption caused by dirty filters. The main control board ensures that each cleaning is completed efficiently without causing unnecessary interference to the user by precisely controlling the working time and intensity of the cleaning component.

[0114] In one embodiment, the method further comprises:

[0115] When the filter screen is cleaned, the blades are controlled to stop rotating.

[0116] The rotation of the blades will generate a strong airflow, which may not only blow away the dust that has just been brushed up by the cleaning brush 1031, resulting in incomplete cleaning, but may also cause the dust to re-attach to the filter. By controlling the blades to stop rotating, this airflow interference can be eliminated, ensuring that the cleaning brush can more effectively contact and remove dirt on the filter, improving cleaning efficiency and quality. During the cleaning process, if the blades continue to rotate, it may cause physical damage to the cleaning components or the filter itself, and even pose a safety hazard. For example, high-speed rotating blades may collide or rub against the cleaning brush, causing equipment damage or failure. Stopping the blades from rotating can avoid these potential risks and ensure the safety and reliability of the cleaning process.

[0117] When the blades stop rotating, the overall load of the fan system is reduced, reducing the working pressure of the motor and other components. This not only helps to extend the service life of the motor and other key components, but also ensures that the cleaning components operate in a stable working environment, further improving the cleaning effect and system reliability. In addition, by controlling the blades to stop rotating, users can get a quieter and smoother operating environment during the cleaning process. After cleaning is completed, the system can restore the normal operation of the blades to provide continuous and stable air circulation and cooling effects. This design not only improves user satisfaction, but also enhances trust and dependence on the equipment.
