[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] The fan device provided in the embodiments of this application, such as Figure 1As shown, the fan device includes a control component 110, a filter 120, a cleaning component 130, a drive motor 140, a camera component 150, a notification component 160, a fan blade 170, a fan blade motor 180, and a wind speed detection component 190. The control component 110 is connected to the drive motor 140, the camera component 150, the notification component 160, and the fan blade motor 180.

[0049] In this embodiment, the fan unit should at least include a base, a support frame, an operation panel, and a fan head. The fan blades 170 and filter 120 are both disposed inside the fan head. The fan head also includes a front mesh and a rear mesh, where the front mesh serves as the fan's air delivery mesh and the rear mesh serves as the fan head's air intake mesh. When the fan unit delivers air, the incoming air passes sequentially through the rear mesh, filter 120, and front mesh, and is then delivered towards the air delivery direction of the fan head. In this embodiment, when the fan unit delivers air according to a preset speed and mode, the fan motor 180 starts, and the fan motor drives the fan blades 170 to rotate, achieving the corresponding preset speed and mode airflow output.

[0050] In this embodiment, filter 120 can be used to filter dust, lint, and other impurities in the air to ensure that the fan equipment can output clean air. The specific structure of filter 120 can be configured according to the needs of the actual application scenario. It should be noted that the mesh size of filter 120 is smaller than the mesh size of the front and rear filters.

[0051] The cleaning component 130 can be a cleaning brush or other tool capable of cleaning the mesh surface. It should be noted that the materials of the cleaning component 130 will not damage the filter screen 120. In this embodiment, the cleaning component 130 is connected to the drive motor 140, and the cleaning component 130 is disposed between the rear mesh of the fan head and the filter screen 120. In specific implementations, when the drive motor 140 is not running, the cleaning brush head of the cleaning component 130 may or may not directly contact the filter screen 120. If the cleaning brush head of the cleaning component 130 does not contact the filter screen 120 when the drive motor 140 is not running, then after the drive motor 140 starts, the drive motor 140 will first move the cleaning component 130 to the target position, causing the cleaning brush head of the cleaning component 130 to contact the filter screen 120. When the drive motor 140 starts, it drives the cleaning brush head of the cleaning component 130 to perform circular or linear motion. The cleaning brush head moves relative to the surface of the filter screen 120, thus removing dust from the surface of the filter screen 120 and cleaning it. It should be noted that the cleaning movement of the cleaning brush head can be determined based on its actual structure and configuration, and the actual position of the cleaning component 130 can be set according to the needs of the specific application scenario.

[0052] In this embodiment, a camera component 150 is also disposed between the rear grille of the fan device and the filter 120, for capturing images of the area where the filter 120 is located. The camera component 150 can be a camera, and the specific type of camera can be determined according to the needs of the actual application scenario. After capturing images of the area where the filter 120 is located, the camera component 150 transmits the images to the control component 110 so that the control component 110 can analyze the cleanliness status of the filter 120 based on the images.

[0053] The prompt component 160 can be one or more of a display unit, a sound unit, or an alarm unit, and the specific type of the prompt component 160 can be configured according to the needs of the actual application scenario. In this embodiment, the prompt component 160 can be a light-emitting unit set on the front grille of the fan head or the body. It should be noted that the prompt component 160 can also be integrated into the display panel of the fan equipment, and the prompt information displayed by the prompt component 160 is directly displayed on the display panel.

[0054] The wind speed detection component 190 can be an anemometer or a flow meter, used to collect the airflow speed of the fan equipment. In this embodiment, the wind speed detection component 190 is disposed between the front grille of the fan head and the fan blades 170.

[0055] In one embodiment, such as Figure 2 As shown, a fan control method is provided, which is applied to... Figure 1 Taking the fan device in the example, the following steps are included:

[0056] S201, When the fan equipment is in the air supply state, perform a health check on the air supply of the fan equipment.

[0057] In this embodiment, when the fan device delivers air according to the set speed and mode, the entire system continuously monitors the airflow status of the fan device to identify its health status. Each speed and mode of the fan device includes standard reference airflow parameters, such as the drive power of the fan motor (air intake volume) and the airflow speed. It should be noted that when the fan device is in normal operation, a higher drive power of the fan motor results in a larger air intake volume, a larger airflow volume, and a faster airflow speed.

[0058] This embodiment collects real-time air supply parameters of the fan device in the air supply state and compares the real-time air supply parameters with the reference air supply parameters. If the real-time air supply parameters do not correspond to the reference air supply parameters, it can be determined that the air supply status of the fan device is abnormal.

[0059] It should be noted that if the real-time air supply parameters correspond to the reference air supply parameters, and the air supply of the fan equipment is determined to be in a normal state, then the subsequent steps will not be executed.

[0060] S202, Perform a fan self-cleaning test when the air supply of the fan equipment is in an abnormal state.

[0061] In this embodiment, after the fan's airflow becomes abnormal, a fan self-cleaning test is further performed to check whether the fan's filter needs cleaning. It should be noted that in practical applications, if the fan's airflow is abnormal and the fan self-cleaning test result indicates that the filter is not clean (i.e., the fan does not need cleaning), the fan unit should prompt the user to check for malfunctions in other components.

[0062] This embodiment performs health checks and fan self-cleaning checks by monitoring the airflow of the fan equipment. This can accurately determine whether the fan equipment's filter needs cleaning, thus avoiding increased energy consumption caused by frequent operation of the cleaning components.

[0063] S203, if the fan self-cleaning detection result indicates immediate cleaning, controls the drive motor to start, thereby driving the cleaning component to clean the filter.

[0064] In this embodiment, if the fan self-cleaning detection result indicates immediate cleaning, it means that impurities on the fan's filter screen are affecting its normal operation. The fan control drive motor starts, moving the cleaning component to the target position. The cleaning brush head of the cleaning component contacts the filter screen surface. After the cleaning component moves to the target position, the drive motor drives the cleaning brush head to perform sliding cleaning. The relative movement between the cleaning brush head and the filter screen surface causes the cleaning brush head to remove impurities from the filter screen, thus achieving filter cleaning. It should be noted that the specific sliding cleaning motion can be selected according to the needs of the actual application scenario, such as parallel sliding, vertical sliding, circular sliding, Z-shaped sliding, etc.

[0065] In summary, this embodiment provides a fan control method that enables real-time monitoring of the fan filter. When abnormal airflow from the fan is detected or the fan filter needs cleaning, the drive motor is activated to drive the cleaning component to achieve self-cleaning of the filter. During long-term use of the fan, the airflow quality of the fan equipment can be guaranteed, and while reducing fan energy consumption, the frequency of manual cleaning and replacement of the filter by the user is reduced, thus improving the user experience of the fan equipment.

[0066] In one embodiment, such as Figure 3 As shown, the fan device includes a camera assembly for capturing images of the area where the filter is located; as Figure 3 As shown, the steps for fan self-cleaning detection include:

[0067] S301, acquire a real-time image of the filter area.

[0068] S302 identifies the degree of dirtiness of the filter by recognizing real-time images based on a preset dirt image database.

[0069] S303 outputs fan self-cleaning test results based on the degree of filter dirtiness. The fan self-cleaning test results include immediate cleaning, waiting for cleaning, and no cleaning.

[0070] In this embodiment, the preset dirt image database is a pre-collected and trained filter image database that includes multiple images of fan filters with different levels of dirt. In a specific embodiment, real-time images can be compared with images in the preset dirt image database, and the degree of dirt on the filter can be determined based on the comparison results.

[0071] In this embodiment, the degree of filter dirtiness includes light dirtiness, moderate dirtiness, and heavy dirtiness. It should be noted that the classification of filter dirtiness can be chosen appropriately based on the needs of the actual application scenario. For example, the degree of filter dirtiness can be determined based on the area of ​​dust coverage on the filter surface. Alternatively, it can be determined based on the passage area of ​​the mesh openings on the filter surface.

[0072] In this embodiment, as Figure 4 As shown, the fan self-cleaning test results are output based on the degree of filter dirtiness, including:

[0073] S401 outputs a self-cleaning test result for the fan, indicating immediate cleaning when the filter is heavily soiled.

[0074] S402 outputs a self-cleaning test result for the fan, indicating that it is awaiting cleaning, when the filter is moderately dirty.

[0075] S403 outputs a self-cleaning test result for an unclean fan when the filter is only slightly dirty.

[0076] In one embodiment, such as Figure 5 As shown, the preset dirt image database includes reference images with different levels of dirt. Based on this database, real-time images are identified to determine the filter's dirt level, including:

[0077] S501, compare the reference image and the real-time image, and select the target reference image that has the greatest similarity to the real-time image;

[0078] S502, determine the degree of dirtiness of the real-time image as the degree of dirtiness of the target reference image.

[0079] In this embodiment, the step of determining the degree of dirtiness of the real-time image as the degree of dirtiness of the target reference image includes the following three scenarios: Scenario 1: The real-time image has the highest similarity to a reference image with a degree of heavy dirtiness, and the real-time image is determined to be heavily dirty. Scenario 2: The real-time image has the highest similarity to a reference image with a degree of moderate dirtiness, and the real-time image is determined to be moderately dirty. Scenario 3: The real-time image has the highest similarity to a reference image with a degree of light dirtiness, and the real-time image is determined to be lightly dirty.

[0080] In this embodiment, the similarity calculation algorithm between the reference image and the real-time image can be selected according to the needs of the actual application scenario.

[0081] In one embodiment, the fan device further includes a prompting component; such as Figure 6 As shown, the fan control method also includes:

[0082] S601, if the result of the fan self-cleaning detection is to clean immediately, the control prompt component will prompt the fan to clean according to the first prompt mode and automatically generate a fan cleaning command, wherein the fan cleaning command is used to control the start of the drive motor.

[0083] S602, when the result of the fan self-cleaning detection is "waiting for cleaning", the control prompt component provides a fan cleaning prompt according to the second prompt mode, and generates a fan cleaning command upon receiving a start signal.

[0084] S603, if the fan self-cleaning detection result is that the fan is not clean, the control prompt component will provide a fan cleaning prompt according to the third prompt mode, without generating a fan cleaning command.

[0085] In this embodiment, the fan cleaning prompts for the first, second, and third prompt modes are different. Taking the display component as the prompting component as an example, the prompting component may display red light when providing fan cleaning prompts in the first prompt mode. In the second prompt mode, it may display yellow light. In the third prompt mode, it may display green light.

[0086] Taking a buzzer as the alerting component as an example, the first alerting mode corresponds to a fast alarm frequency, the second alerting mode corresponds to a medium alarm frequency, and the third alerting mode does not trigger an alarm. It should be noted that each alerting mode can be adaptively configured according to the specific type of alerting component.

[0087] In this embodiment, if the fan self-cleaning detection result indicates immediate cleaning, the control method executed by the fan device can refer to the specific implementation method in the previous embodiments, and will not be repeated here. If the fan self-cleaning detection result indicates waiting for cleaning, the fan device only generates a fan cleaning command to control the drive motor to start when it receives a start signal from the remote control or when the user sends a start signal by operating the fan device's display panel or function keys.

[0088] In one embodiment, the fan device includes a wind speed detection component for collecting the airflow speed of the fan device; and performs a health check on the airflow of the fan device, including:

[0089] Obtain the real-time airflow speed of the fan device; compare the real-time airflow speed with the target airflow speed threshold, where the target airflow speed threshold is the standard airflow speed corresponding to the current airflow setting of the fan device; if the absolute value of the difference between the real-time airflow speed and the target airflow speed threshold is greater than or equal to a preset difference threshold, determine that the airflow of the fan device is in an abnormal state.

[0090] In this embodiment, if the filter of the fan device is highly contaminated, the real-time airflow speed will be lower than the target airflow speed threshold. This embodiment determines whether there is an airflow abnormality in the fan device by identifying the difference between the fan device's airflow speed and the target airflow speed threshold, and thus determines whether the fan device's filter needs cleaning.

[0091] In one embodiment, the fan device further includes fan blades and a fan blade motor, the fan blade motor being used to drive the fan blades to rotate; the health monitoring of the air delivery status of the fan device also includes:

[0092] Obtain the real-time input power of the fan motor; if the absolute value of the difference between the real-time input power of the fan motor and the reference power corresponding to the current air supply level is greater than the preset difference threshold, determine that the air supply of the fan equipment is in an abnormal state.

[0093] In this embodiment, if the filter of the fan device is heavily soiled, some intelligent fan devices will increase the input power of the fan motor to maintain the target wind speed corresponding to the current airflow level, ensuring that the airflow parameters are not affected by the filter's condition. This embodiment identifies the real-time input power of the fan motor and compares it with the reference power corresponding to the current airflow level. The power difference between the fan motor and the reference power determines whether there is an airflow abnormality in the fan device, and thus whether the fan filter needs cleaning.

[0094] In one embodiment, the fan control method further includes:

[0095] When the fan is powered on, perform a self-cleaning test according to a preset cycle.

[0096] In this embodiment, when the fan device is in long-term use, the condition of the fan filter needs to be monitored regularly to ensure that the fan filter can be cleaned in a timely manner, thus ensuring the cleanliness of the fan filter and the air delivery quality of the fan device.

[0097] In summary, this embodiment provides a fan control method that uses a visual solution to monitor the real-time status of the fan filter's dirt condition. This allows for accurate determination of whether the fan filter needs automatic dust removal. Furthermore, by combining the prompting components and various fan parameter detection components on the fan device, it ensures accurate monitoring and timely feedback of the fan device's health status. It can promptly remind users when the fan filter becomes dirty, enabling them to pay attention to fan malfunctions, promptly check the fan's health, ensure the fan device's performance, and improve the user experience.

[0098] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more fan control device embodiments provided below can be found in the limitations of the fan control method described above, and will not be repeated here.

[0109] In one embodiment, the first detection module 710 is specifically used to obtain the real-time input power of the fan motor; if the absolute value of the difference between the real-time input power of the fan motor and the reference power corresponding to the current air supply level is greater than a preset difference threshold, it is determined that the air supply of the fan device is in an abnormal state.

[0110] In one embodiment, the second detection module 720 is specifically used to perform fan self-cleaning detection according to a preset cycle when the fan device is powered on.
