[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] The fan device provided in the embodiment of the present application is as follows: Figure 1As shown, the fan device includes a control component 110, a filter 120, a cleaning component 130, a driving motor 140, a camera component 150, a prompt 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 driving motor 140, the camera component 150, the prompt component 160 and the fan blade motor 180 respectively.

[0049] In this embodiment, the body of the fan device should at least include a base, a support frame, an operation panel and a fan head, and the fan blades 170 and the filter screen 120 are both arranged inside the fan head. The fan head also includes a front net and a rear net, wherein the front net is the air supply grid of the fan, and the rear net is the air inlet grid of the fan head. When the fan device supplies air, the incoming air passes through the rear net, the filter screen 120 and the front net in sequence, and then is sent out in the air supply direction of the fan head. In this embodiment, when the fan device supplies air according to the preset gear and mode, the fan blade motor 180 is started, and the wind turbine motor is used to drive the fan blades 170 to rotate, so as to achieve the air volume output corresponding to the preset gear and mode.

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

[0051] The cleaning component 130 can be a cleaning brush or other tools capable of cleaning the mesh surface. It should be noted that the constituent materials of the cleaning component 130 will not cause damage to the filter 120. In the present 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 120. In a specific implementation, when the drive motor 140 is not started, the cleaning brush head of the cleaning component 130 may directly contact the filter 120 or may not contact the filter 120. If the cleaning brush head of the cleaning component 130 does not contact the filter 120 when the drive motor 140 is not started, then after the drive motor 140 is started, the drive motor 140 will first drive the cleaning component 130 to move to the target position so that the cleaning brush head of the cleaning component 130 contacts the filter 120. When the driving motor 140 is started, it drives the cleaning brush head of the cleaning component 130 to perform circular motion or cyclic linear motion, and the cleaning brush head and the surface of the filter 120 move relative to each other to remove dust from the surface of the filter 120, thereby achieving dust removal and cleaning of the filter 120. It should be noted that the cleaning movement mode of the cleaning brush head can be determined according to the actual structure and setting mode of the cleaning brush head, and the actual setting position of the cleaning component 130 can be set according to the needs in the actual application scenario.

[0052] In this embodiment, the camera assembly 150 is also disposed between the rear screen of the fan device and the filter 120, and is used to capture an image of the area where the filter 120 is located. The camera assembly 150 may be a camera, and the specific type of the camera may be determined according to the needs of the actual application scenario. After capturing an image of the area where the filter 120 is located, the camera assembly 150 transmits the image to the control assembly 110, so that the control assembly 110 analyzes the cleanliness status of the filter 120 based on the image.

[0053] The prompt component 160 may be one or more of a display unit, a sound unit, or an alarm unit. The specific type of the prompt component 160 may be configured according to the needs of the actual application scenario. In this embodiment, the prompt component 160 may be a light-emitting unit disposed on the front grille or body of the fan head. It should be noted that the prompt component 160 may also be integrated into the display panel of the fan device, 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, which is used to collect the air supply wind speed of the fan device. In this embodiment, the wind speed detection component 190 is arranged between the front net of the fan head and the fan blades 170.

[0055] In one embodiment, Figure 2 As shown, a fan control method is provided, which is applied to Figure 1 The fan device in the example is used as an example to illustrate the process, including the following steps:

[0056] S201, when the fan device is in an air supply state, performing a health check on the air supply condition of the fan device.

[0057] In this embodiment, when the fan device supplies air according to the set gear and set mode, the whole machine will judge the air supply condition of the fan device in real time, so as to identify the health status detection of the fan device through the air supply condition of the air supply device. Among them, each gear and mode of the fan device includes standard reference air supply parameters, and the reference air supply parameters include the driving power (inlet air volume) of the fan motor, the air supply speed, etc. It should be noted that when the fan device is in a normal state, the greater the driving power of the fan motor, the greater the air intake volume, the greater the air supply volume, and the faster the air supply 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 reference air supply parameters. When the real-time air supply parameters do not correspond to the reference air supply parameters, it can be determined that the air supply condition 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, it is determined that the air supply condition of the fan device is normal, and the subsequent steps are not performed.

[0060] S202: When the air supply of the fan device is in an abnormal state, a fan self-cleaning test is performed.

[0061] In this embodiment, after the air supply of the fan device is abnormal, the fan self-cleaning test is further performed to detect whether the filter of the fan device needs to be cleaned. It should be noted that in actual application, if the air supply of the fan device is in an abnormal state, if the result of the fan self-cleaning test is unclean, that is, the filter of the fan device does not need to be cleaned, the fan device needs to prompt the user to check whether other components of the fan device are faulty.

[0062] This embodiment performs health detection and fan self-cleaning detection through the air supply condition of the fan device, and can accurately determine whether the filter of the fan device needs to be cleaned, thereby avoiding the increase of equipment energy consumption caused by frequent operation of the cleaning component.

[0063] S203, when the result of the fan self-cleaning detection is immediate cleaning, controlling the drive motor to start, so as to drive the cleaning component to clean the filter.

[0064] In this embodiment, when the result of the fan self-cleaning detection is immediate cleaning, it means that the impurities on the filter screen of the fan device have affected the normal use of the fan device. The fan device controls the drive motor to start, so that the cleaning component moves to the target position, and the cleaning brush head of the cleaning component contacts the surface of the filter screen. After the cleaning component moves to the target position, the drive motor drives the cleaning brush head to slide and clean, and the cleaning brush head and the surface of the filter screen move relative to each other. The cleaning brush head hangs on the impurities on the filter screen to clean the filter screen. It should be noted that the specific movement mode of sliding cleaning can be selected according to the needs of the actual application scenario, such as parallel sliding, vertical sliding, circular sliding, Z-type sliding and other modes.

[0065] To sum up, the present embodiment provides a fan control method, which can realize real-time monitoring of the fan filter, and when it is detected that the fan device is blowing abnormally and the fan filter needs to be cleaned, the drive motor is started to drive the cleaning component to realize self-cleaning of the filter. During the long-term use of the fan, the air supply quality of the fan device can be guaranteed, and while reducing the fan energy consumption, the frequency of users manually cleaning and replacing the filter is reduced, thereby improving the user experience of the fan device.

[0066] In one embodiment, if Figure 3 As shown, the fan device includes a camera assembly, which is used to capture images of the area where the filter is located; Figure 3 As shown, the steps of fan self-cleaning detection include:

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

[0068] S302, identifying the real-time image based on a preset dirty image database to obtain the degree of dirtiness of the filter.

[0069] S303, outputting a fan self-cleaning detection result according to the degree of dirtiness of the filter, wherein the fan self-cleaning detection result includes immediate cleaning, waiting for cleaning, and not cleaning.

[0070] In this embodiment, the preset dirty image database is a filter image database collected and trained in advance, including multiple images of fan filters in different dirty conditions. In a specific embodiment, the real-time image can be compared with the image in the preset dirty image database, and the degree of dirtiness of the filter can be determined by the comparison result.

[0071] In this embodiment, the degree of dirtiness of the filter includes light dirtiness, moderate dirtiness and heavy dirtiness. It should be noted that the degree of dirtiness of the filter can be divided in a suitable manner according to the needs of the actual application scenario. For example, the degree of dirtiness of the filter can be determined according to the area of ​​dust coverage on the surface of the filter. The degree of dirtiness of the filter can also be determined according to the passing area of ​​the mesh on the surface of the filter.

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

[0073] S401: When the filter is severely dirty, output a self-cleaning detection result of the fan for immediate cleaning.

[0074] S402: When the filter is moderately dirty, output a self-cleaning detection result of the fan waiting to be cleaned.

[0075] S403: When the filter is slightly dirty, output a self-cleaning detection result of an unclean fan.

[0076] In one embodiment, if Figure 5 As shown, the preset dirty image database includes reference images of different dirt levels. Based on the preset dirty image database, the real-time image is recognized to obtain the degree of dirtiness of the filter, including:

[0077] S501, comparing the reference image and the real-time image, and selecting a target reference image having the greatest similarity with the real-time image;

[0078] S502: Determine the dirtiness of the real-time image as the 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 situations: Situation 1, the real-time image has the greatest similarity with the reference image with a heavy degree of dirtiness, and the degree of dirtiness of the real-time image is determined to be heavy. Situation 2, the real-time image has the greatest similarity with the reference image with a moderate degree of dirtiness, and the degree of dirtiness of the real-time image is determined to be moderate. Situation 3, the real-time image has the greatest similarity with the reference image with a light degree of dirtiness, and the degree of dirtiness of the real-time image is determined to be light.

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

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

[0082] S601, when the result of the fan self-cleaning detection is immediate cleaning, the control prompt component performs a fan cleaning prompt according to a first prompt mode and automatically generates a fan cleaning instruction, wherein the fan cleaning instruction is used to control the start-up of the drive motor.

[0083] S602: When the result of the fan self-cleaning detection is waiting for cleaning, the control prompt component performs a fan cleaning prompt according to a second prompt mode, and generates a fan cleaning instruction when receiving a start signal.

[0084] S603: When the result of the fan self-cleaning detection is unclean, the control prompt component performs a fan cleaning prompt according to a third prompt mode, and does not generate a fan cleaning instruction.

[0085] In this embodiment, the corresponding fan cleaning prompt contents in the first prompt mode, the second prompt mode, and the third prompt mode are different. Taking the display component as the prompt component as an example, the prompt component performs fan cleaning prompts according to the first prompt mode, and the display component may display red light. The prompt component performs fan cleaning prompts according to the second prompt mode, and the display component may display yellow light. The prompt component performs fan cleaning prompts according to the third prompt mode, and the display component may display green light.

[0086] Taking the prompt component as a buzzer as an example, the first prompt mode corresponds to a fast alarm frequency, the second prompt mode corresponds to a medium alarm frequency, and the third prompt mode corresponds to no alarm. It should be noted that each prompt mode can be adaptively configured according to the specific type of the prompt component.

[0087] In this embodiment, the result of the fan self-cleaning detection is immediate cleaning. The control method executed by the fan device can refer to the specific implementation method in the above-mentioned embodiment, which will not be described in detail here. When the result of the fan self-cleaning detection is waiting for cleaning, the fan device generates a fan cleaning instruction to control the start of the drive motor only when it receives a start signal sent by the remote control or the user sends a start signal by operating the display panel or function button of the fan device.

[0088] In one embodiment, the fan device includes a wind speed detection component, which is used to collect the air supply wind speed of the fan device; and the air supply condition of the fan device is health-checked, including:

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

[0090] In this embodiment, if the filter of the fan device is highly dirty, the real-time air supply speed will be less than the target speed threshold. This embodiment determines whether the fan device has air supply abnormality by identifying the difference between the air supply speed of the fan device and the target speed threshold, and further determines whether the filter of the fan device needs to be cleaned.

[0091] In one embodiment, the fan device further includes a fan blade and a fan blade motor, and the fan blade motor is used to drive the fan blade to rotate; and the health detection of the air supply condition of the fan device further includes:

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

[0093] In this embodiment, if the filter of the fan device is highly dirty, some intelligent fan devices will increase the input power of the fan motor to maintain the target wind speed corresponding to the current air supply gear, so as to ensure that the air supply parameters are not affected by the filter status. This embodiment identifies the real-time input power of the fan motor and compares it with the reference power corresponding to the current air supply gear, and then determines whether the fan device has air supply abnormality through the power difference of the fan motor, and then determines whether the filter of the fan device needs to be cleaned.

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

[0095] When the fan device is powered on, the fan self-cleaning test is performed according to the preset period.

[0096] In this embodiment, when the fan device is in long-term use, it is necessary to regularly monitor the status of the fan filter to ensure that the fan filter can be cleaned in time to ensure the cleanliness of the fan filter and the air supply quality of the fan device.

[0097] To summarize, the present embodiment provides a fan control method, which realizes real-time monitoring of the dirtiness of the fan filter through a visual solution, and can accurately determine whether the fan filter needs to be automatically dusted. In combination with the prompt component and various fan parameter detection components set on the fan device, it can ensure accurate monitoring and timely feedback of the health status of the fan device, and can promptly remind the user when the fan filter becomes dirty, so that the user can pay attention to abnormal fan problems, check the health of the fan in time, ensure the use effect of the fan device, and improve the user experience of the fan device.

[0098] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0099] Based on the same inventive concept, the embodiment of the present application also provides a fan control device for implementing the above-mentioned fan control method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above-mentioned method, so the specific limitations in one or more fan control device embodiments provided below can refer to the limitations of the fan control method above, and will not be repeated here.
