[0002] With the increasing severity of environmental pollution, air purifiers, as an important air improvement device, have gradually become an indispensable part of modern homes. Air purifiers can effectively filter particulate matter and harmful gases from the air, improving ambient air quality.

[0003] Traditional air purifiers typically use built-in sensors to detect air quality and then adjust their operating mode based on the results, such as automatically adjusting the air purifier's power level to meet the user's air quality needs.

[0004] However, the adjustment of the working levels of the aforementioned traditional air purifiers is based on a relatively simple method, which results in a lack of intelligent functional design and makes it difficult to meet the diverse needs of modern users. Summary of the Invention

The health monitoring data is sent by the wearable device when the user is at the target location.

[0008] Based on the user's health monitoring data, the user's level of fatigue is determined;

[0026] Based on the user's level of fatigue, the air purifier's fan speed is determined, and the fan speed is positively correlated with the level of fatigue.

[0027] If the user's fatigue level is greater than a preset fatigue level threshold and the air particulate matter concentration is less than or equal to a preset concentration threshold, the negative ion working mode of the air purifier is activated.

[0031] If the concentration of air particulate matter exceeds the preset concentration range, or if the user's sensitivity to air particulate matter is at the first sensitivity level, the air intake parameters of the air purifier are determined to be the second air intake parameters, which include the second air intake area and the second air intake angle.

[0032] Wherein, the first air intake area is smaller than the second air intake area, and the first air intake angle is smaller than the second air intake angle.

Finally, the air purifier is controlled to operate in the determined operating mode and parameters. Unlike traditional air purifiers that rely solely on a single environmental sensor to detect air quality and adjust their operating mode, this solution integrates multi-source data such as user status, environment, vision, and sound to achieve comprehensive perception of user needs and environmental conditions. This allows the air purifier's operating parameters to be dynamically adjusted according to complex and changing user needs and environmental conditions, improving the intelligence level of the air purifier's operating mode adjustment and meeting the diverse and personalized air purification needs of modern users.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and embodiments, will further illustrate the content of this application. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0058] The air purifier control method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with controller 104 via a network. A data storage system can store the data that controller 104 needs to process. The data storage system can be integrated onto controller 104 or placed in the cloud or on another network server.

[0059] For example, when a user is at a target location, a wearable device worn by the user sends the user's health monitoring data to the controller 104. This target location can be the user's residence, workplace, etc. When the air purifier is at the target location, various sensors in the air purifier are triggered to collect the concentration of airborne particulate matter at the target location, as well as the user's image and sound data. This data can be sent to the controller 104 by staff via terminal 102, or it can be automatically sent by the various sensors. Based on the user's health monitoring data, the controller 104 determines the user's fatigue level, and based on the user's image and sound data, determines the user's sensitivity to airborne particulate matter. Then, based on the user's fatigue level, airborne particulate matter concentration, and user's sensitivity to airborne particulate matter, the controller 104 determines the air purifier's operating mode and parameters. Finally, the controller 104 controls the air purifier to operate according to the operating mode and parameters.

[0060] The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle systems, and projection devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted displays. Head-mounted displays can be virtual reality (VR) devices, augmented reality (AR) devices, and smart glasses. The controller 104 can be an independent physical controller, a controller cluster or distributed system composed of multiple physical controllers, or a cloud controller providing cloud computing services.

[0061] In one exemplary embodiment, such as Figure 2 As shown, an air purifier control method is provided, which is applied to... Figure 1 Taking controller 104 as an example, the following steps are included:

[0062] S100, in response to the user's health monitoring data sent by the wearable device, collects the air particulate matter concentration at the target location, as well as the user's image and sound data.

[0063] The health monitoring data is transmitted by wearable devices when the user is at the target location. Wearable devices are portable electronic devices that can be worn directly on the user's body or integrated into the user's clothing or accessories, such as smartwatches and smart bracelets. They have data collection and transmission functions, and can collect the user's health monitoring data in real time, such as heart rate, blood pressure, and steps, and send the health monitoring data to the air purifier's receiving end via wireless communication modules (such as Bluetooth, Wi-Fi, etc.). The target location is the location where the air purifier is located, such as the user's home or workplace, which is a place where air purification is required. Air particulate matter concentration is the number or mass of particulate matter contained in a unit volume of air, used to characterize the air quality at the target location, and can be collected by the air particulate matter concentration sensor in the air purifier. Image data is the visual information of the user at the target location obtained by the image acquisition device in the air purifier, which can be used to analyze the user's facial expressions, body movements, and other features. Sound data is the sound information emitted by the user at the target location, such as voice and cough, collected by the sound acquisition device (such as a microphone) in the air purifier.

[0064] Specifically, taking a user's home as the target location (which the user can pre-set) and a smartwatch as the wearable device, the smartwatch can monitor the user's distance from home. For example, when the user is 1 kilometer away, the smartwatch can begin collecting and recording the user's health monitoring data, such as heart rate and steps. Upon arrival home, the smartwatch sends this data to an air purifier. Upon receiving the health monitoring data, the air purifier triggers its particulate matter concentration sensor to collect the concentration of particulate matter in the home. Simultaneously, it activates its image and sound acquisition devices to obtain the user's image and sound data, respectively, as the basis for subsequent analysis of the user's condition and the environmental situation.

[0065] The S200 determines a user's level of fatigue based on their health monitoring data.

[0066] Among them, fatigue level is an indicator that reflects the degree of physical or mental fatigue of the user, and can be assessed based on the user's health monitoring data.

[0067] Specifically, after receiving health monitoring data from wearable devices, such as the user's average heart rate and average number of steps per kilometer within 1 kilometer of home, the air purifier can analyze the user's fatigue level based on the average heart rate and average number of steps. For example, it can classify the user's fatigue level into mild fatigue, moderate fatigue, and severe fatigue through machine learning models or preset rule bases.

[0068] The S300 determines a user's sensitivity to airborne particulate matter based on the user's image and sound data.

[0069] Sensitivity is used to characterize the degree to which a user reacts to airborne particulate matter, reflecting the likelihood and severity of discomfort symptoms that a user may experience when exposed to airborne particulate matter.

[0070] Specifically, the air purifier analyzes image data collected by the image acquisition device and sound data collected by the sound acquisition device. For image data, image recognition technology can be used to analyze the user's facial expressions (such as whether they rub their eyes or frown) and skin condition (such as whether they have allergy symptoms like redness and swelling). For sound data, speech recognition and sound feature analysis technology can be used to determine whether the user is coughing, sneezing, or making other sounds, as well as the frequency and intensity of those sounds. Then, based on the user's facial expressions, skin condition, and sound characteristics, it can determine whether the user is exhibiting allergic behaviors such as coughing or sneezing, and further classify the user's sensitivity to airborne particles into mild, moderate, and high sensitivity based on the frequency of these allergic behaviors.

[0071] The S400 determines the air purifier's operating mode and parameters based on the user's fatigue level, air particulate matter concentration, and the user's sensitivity to air particulate matter.

[0072] The operating mode refers to the different ways the air purifier operates, such as automatic mode, sleep mode, and negative ion mode. Each mode corresponds to different operating strategies and function combinations. Operating parameters are specific indicators of the air purifier's operating status, such as fan speed, air intake area, and air intake angle.

[0073] Following the steps above, the air purifier, based on the fatigue level, particulate matter concentration, and user sensitivity to particulate matter determined in the previous steps, can perform a comprehensive analysis using preset operating modes and parameters. For example, when the user is severely fatigued, the air purifier can be set to negative ion mode with high fan speed. Negative ions promote blood circulation, enhance immunity, regulate the nervous system, and stimulate endorphin release, helping to relieve fatigue and improve mood. High fan speed also improves indoor air circulation and increases oxygen levels, further aiding in fatigue relief. If the particulate matter concentration is high and the user is highly sensitive to particulate matter, full air intake and a wide air intake angle can be used to accelerate the removal of particulate matter from the environment.

[0074] S500 controls the air purifier's operation in its working mode and with its operating parameters.

[0075] Following the steps above, after the controller in the air purifier determines the working mode and working parameters, the controller converts the working mode and working parameters into control commands and sends them to the corresponding working modules of the air purifier to control the corresponding working modules to start running according to the working mode and working parameters.

[0076] The aforementioned air purifier control method, when the user is at the target location, sends the user's health monitoring data to the air purifier via a wearable device. This triggers the air purifier to collect the concentration of airborne particulate matter at the target location, as well as the user's image and sound data. This provides a basis for subsequent assessment of the user's sensitivity to airborne particulate matter. Furthermore, based on the user's health monitoring data, the user's fatigue level is determined; based on the user's image and sound data, the user's sensitivity to airborne particulate matter is determined. The fatigue level, the concentration of particulate matter in the environment, and the user's sensitivity to airborne particulate matter are used as the basis for adjusting the air purifier, determining the air purifier's operating mode and parameters. Finally, the air purifier is controlled to operate within the determined operating mode and parameters. Unlike traditional air purifiers that rely solely on a single environmental sensor to detect air quality and adjust their operating mode, this solution integrates multi-source data such as user status, environment, vision, and sound to achieve comprehensive perception of user needs and environmental conditions. This allows the air purifier's operating parameters to be dynamically adjusted according to complex and changing user needs and environmental conditions, improving the intelligence level of the air purifier's operating mode adjustment and meeting the diverse and personalized air purification needs of modern users.

[0077] In one exemplary embodiment, health monitoring data includes average heart rate and average steps, such as Figure 3 As shown, S200 includes:

[0078] S210: If the average heart rate is greater than the preset heart rate threshold and the average number of steps is greater than the preset step threshold, the user is determined to be in the first level of fatigue.

[0079] S220 determines that the user is in the second level of fatigue if the average heart rate is greater than the preset heart rate threshold or the average number of steps is greater than the preset step threshold.

[0080] S230 determines that the user is in the third level of fatigue when the average heart rate is less than or equal to the preset heart rate threshold and the average number of steps is less than or equal to the preset number of steps threshold.

[0081] The average heart rate is the average value calculated by the wearable device after collecting heart rate data from the user within a specific time period or exercise range. For example, data collection begins when the user is one kilometer away from the target location, and the average heart rate is calculated after the user reaches the target location. The average steps are the cumulative number of steps taken by the user within a certain period of time, such as calculating the average number of steps taken by the user within one kilometer of the target location. Fatigue levels include a first, second, and third level of fatigue, decreasing sequentially. The first level of fatigue indicates that the user is at a high level of fatigue and needs timely rest and adjustment. The second level of fatigue is lower than the first level but still indicates that the user needs appropriate relaxation. The third level of fatigue is the lowest level, indicating that the user's physical condition is relatively good and the feeling of fatigue is weak.

[0082] Specifically, after receiving average heart rate and average step count data from the wearable device, the controller in the air purifier compares the average heart rate with a preset heart rate threshold, and the average step count with a preset step count threshold. Only when both the average heart rate and average step count are greater than the preset heart rate and step count thresholds is the user considered to be in the first level of fatigue. This is because when both the user's heart rate and step count are at high levels, it means the body is under significant stress during exercise, and prolonged or high-intensity activity in this state can easily lead to deep fatigue, hence it is classified as the highest level of fatigue. If either the average heart rate or average step count is greater than the preset heart rate or step count threshold, the user is classified to be in the second level of fatigue. This is because in reality, an abnormally high heart rate or excessive activity level can, even with a single factor, cause fatigue, thus classifying the user as being in the first level of fatigue, which is lower than the first level. When the average heart rate is less than or equal to the preset heart rate threshold, and the average number of steps is also less than or equal to the preset number of steps threshold, the user is judged to be in the third level of fatigue. This indicates that the user's activity intensity and cardiac activity intensity at the target location are within the normal range, the body has not experienced significant fatigue, and the user is in a relatively relaxed state.

[0083] In this embodiment, a simple and effective fatigue level determination mechanism is constructed using two indicators that can intuitively reflect the user's physical activity status: average heart rate and average steps. This mechanism can quickly and accurately classify the user's fatigue level, providing a precise basis for determining the user's status in the subsequent determination of the air purifier's working mode and parameters. This allows the air purifier to make differentiated adjustments based on the user's fatigue level, thereby improving the intelligence of the air purifier.

[0084] In one exemplary embodiment, such as Figure 4 As shown, S300 includes:

[0085] S310 determines whether a user has an allergic reaction based on the user's image and sound data.

[0086] In the event of an allergic reaction, the S320 determines the user's sensitivity to airborne particulate matter to the highest level.

[0087] S330 determines the user's sensitivity to airborne particulate matter to the second level, assuming no allergic reaction occurs.

[0088] Allergic reactions refer to abnormal immune responses that occur after a user comes into contact with allergens such as airborne particulate matter. In this embodiment, allergic reactions include, but are not limited to, skin redness and itching, conjunctival congestion and frequent eye rubbing, and respiratory symptoms such as coughing and sneezing. The first level of sensitivity indicates that the user is highly sensitive to airborne particulate matter and requires more powerful air purification measures to reduce the irritation caused by these particles. The second level of sensitivity represents a relatively low level of sensitivity; in the same airborne particulate matter environment, compared to users with the first level of sensitivity, the probability and severity of allergic reactions are lower, and the need for air purification is relatively weaker. In other words, the first level of sensitivity is greater than the second level of sensitivity.

[0089] Specifically, after receiving image data from the image acquisition device and sound data from the sound acquisition device, the air purifier's controller can process the image and sound data using image recognition algorithms and sound analysis algorithms, respectively. For image data, a trained deep learning model can be used to identify changes in the user's skin color, eye redness, and whether actions such as facial scratching, sneezing, or coughing are occurring. For sound data, sound feature extraction algorithms can be used to identify the frequency, intensity, and waveform characteristics of coughs and sneezes. Based on the analysis results of these image and sound features, it can be determined whether the user is experiencing an allergic reaction.

[0090] If a user experiences an allergic reaction, whether it's skin, eyes, or respiratory symptoms, their sensitivity to airborne particulate matter is classified as Level 1. This is because an allergic reaction indicates a high level of sensitivity to particulate matter in the current environment, requiring the air purifier to operate at its highest power to quickly reduce the concentration of particulate matter. If the user does not experience any allergic reaction, their sensitivity to airborne particulate matter is classified as Level 2, meaning their sensitivity to particulate matter in the current environment is relatively low.

[0091] In this embodiment, based on the user's intuitive external behavior and sound information, the user's sensitivity to airborne particulate matter can be quickly and accurately identified. This allows for a more objective and real-time assessment, enabling timely adjustment of the air purifier's operating mode and parameters according to the user's status. Furthermore, this real-time sensitivity-based judgment mechanism provides users with personalized air purification services, offering differentiated treatment for users with varying levels of sensitivity. This better meets users' air quality needs in different environments and enhances user comfort when using the air purifier.

[0092] In one exemplary embodiment, such as Figure 5 As shown, S400 includes:

[0093] The S410 determines whether to activate the negative ion mode of the air purifier and the air purifier's fan speed based on the user's fatigue level and the concentration of air particulate matter.

[0094] S420 determines the air intake parameters of the air purifier based on the concentration of air particulate matter and the user's sensitivity to air particulate matter.

[0095] The operating parameters of an air purifier include fan speed and air intake parameters. The negative ion mode is a special operating mode of an air purifier. In this mode, the built-in negative ion generator produces negative ions and releases them into the air. Negative ions can adsorb particulate matter in the air, causing it to become charged and aggregate, thus settling and purifying the air, especially effective at removing fine particulate matter (such as PM2.5). Fan speed is the speed at which air flows through the air purifier's outlet when the fan is running. Generally, the higher the fan speed, the greater the amount of air passing through the purifier per unit time, and the faster the purification speed. Air intake parameters are indicators describing the operating status of the air purifier's air intake, including the opening area and angle of the air intake.

[0096] Specifically, after determining the user's fatigue level and the collected air particulate matter concentration, when the user is at a high level of fatigue (such as level one or level two fatigue), negative ions can help relieve fatigue and improve mood by promoting blood circulation and stimulating the release of endorphins. Therefore, the negative ion mode of the air purifier should be activated at this time, and the fan speed should be set to a higher level to ensure air circulation, increase indoor oxygen content, and also help relieve fatigue. If the user is at level three fatigue and the air particulate matter concentration is low, the negative ion mode can be deactivated, and a lower fan speed can be selected to reduce noise and energy consumption while ensuring air quality. In addition, if the air particulate matter concentration is low, such as PM2.5 ≤ 10 (unit is micrograms per cubic meter, the same below, will not be repeated), the negative ion mode of the air purifier can be kept on. If the air particulate matter concentration is high, such as 10 < PM2.5 ≤ 50, the negative ion mode of the air purifier can be turned off to mainly reduce the air particulate matter concentration.

[0097] Furthermore, the air intake parameters of an air purifier can be determined based on the concentration of particulate matter in the environment and the user's sensitivity to it. For situations with high particulate matter concentrations and the user's level of sensitivity (primarily low), the opening area of ​​the air intake can be increased, and the airflow velocity can be appropriately increased to allow more polluted air to enter the air purifier for processing, in order to more efficiently capture pollutants. When the particulate matter concentration is low and the user's sensitivity is at a secondary level, the opening area of ​​the air intake and the airflow velocity can be appropriately reduced to maintain basic air purification needs and reduce equipment energy consumption and noise.

[0098] In this embodiment, by comprehensively considering factors such as user fatigue level, air particulate matter concentration, and user sensitivity to air particulate matter, the working mode and parameters of the air purifier are accurately and personally determined. This breaks the traditional single operating mode of air purifiers and enables personalized purification solutions to be provided for different user states and environmental conditions.

[0099] In one exemplary embodiment, such as Figure 6 As shown, S410 includes:

[0100] S411 determines the air purifier's fan speed based on the user's fatigue level, with fan speed being positively correlated with fatigue level.

[0101] S412, when the user's fatigue level is greater than the preset fatigue level threshold and the air particulate matter concentration is less than or equal to the preset concentration threshold, determine to start the negative ion working mode of the air purifier.

[0102] Specifically, when a user's fatigue level exceeds a fatigue threshold, for example, by determining the user's fatigue level to be a first fatigue level or a second fatigue level through the steps in the above embodiments, it can be determined that the user's fatigue level exceeds the fatigue threshold. In this embodiment, the higher the user's fatigue level, the higher the air purifier's fan speed can be controlled, because a high fan speed can maintain indoor air circulation, increase oxygen content, and help alleviate fatigue.

[0103] Specifically, the user's fatigue level can be classified into three levels—first, second, and third—using the steps described in the above embodiments, and a corresponding fan speed range can be assigned to each level. For example, when a user is at the first level of fatigue, indicating extreme physical exhaustion, the air purifier's fan speed should be set to the highest level to quickly purify the air, creating a more comfortable breathing environment and helping to alleviate fatigue. If the user is at the third level of fatigue, indicating a relatively good physical condition, the fan speed can be set to a lower level to reduce operating noise and energy consumption while ensuring air quality.

[0104] Furthermore, when a user's fatigue level is at the first or second level, it can be assumed that the user's fatigue level is greater than a preset fatigue threshold. Only when the concentration of air particulate matter is less than or equal to a preset concentration threshold (e.g., PM2.5 ≤ 10) should the negative ion mode of the air purifier be activated. This not only further improves air quality and increases air freshness but also utilizes the properties of negative ions (such as soothing nerves and promoting metabolism) to help alleviate user fatigue. In other words, even if the user's fatigue level is at the first or second level, if the concentration of air particulate matter is greater than a preset concentration threshold (e.g., 10 < PM2.5 ≤ 50), the negative ion mode should be deactivated.

[0105] In this embodiment, by combining the air purifier's fan speed and negative ion working mode with the user's fatigue level and air particulate matter concentration, precise adaptation to the user's actual needs is achieved. When the air particulate matter concentration is low, the negative ion working mode is only activated when the user's fatigue level is high, thus achieving targeted improvement of the user's fatigue state and enhancing the personalization and intelligence of the air purifier.

[0106] In one exemplary embodiment, the sensitivity includes a first sensitivity and a second sensitivity, wherein the first sensitivity is greater than the second sensitivity, such as... Figure 6 As shown, S420 includes:

[0107] S421, when the concentration of air particulate matter is within a preset range and the user's sensitivity to air particulate matter is at the second level, the air intake parameter of the air purifier is determined to be the first air intake parameter.

[0108] S422, when the concentration of air particulate matter exceeds the preset concentration range, or when the user's sensitivity to air particulate matter is at the first level of sensitivity, the air intake parameter of the air purifier is determined to be the second air intake parameter.

[0109] The first air intake parameter includes the first air intake area and the first air intake angle, while the second air intake parameter includes the second air intake area and the second air intake angle. The first air intake area is smaller than the second air intake area, and the first air intake angle is smaller than the second air intake angle. The first air intake area refers to the effective area of ​​the air intake opening, and the first air intake angle represents the angle between the air intake and a specific direction (such as the horizontal direction). Compared to the first air intake parameter, the second air intake area is larger and the second air intake angle is larger, enabling the air purifier to draw in more air and complete air purification faster.

[0110] For example, after acquiring the air particulate matter concentration data and the user's sensitivity data to air particulate matter, the air particulate matter concentration can be compared with a preset concentration range, and it can be determined whether the user's sensitivity is at the second level. When the air particulate matter concentration is within the preset concentration range and the user's sensitivity to air particulate matter is at the second level, it indicates that the current air quality is acceptable and the user's sensitivity to air particulate matter is relatively low. At this time, the air intake parameters of the air purifier can be determined as the first air intake parameters, that is, the air intake area of ​​the air purifier's air intake is set as the first air intake area and the air intake angle is set as the first air intake angle. For example, the first air intake area is half air intake (considering that air particulate matter is generally higher than air, so it is the lower half of the air intake), and the first air intake angle is 10-30 degrees.

[0111] If the concentration of airborne particulate matter exceeds the preset range, it indicates poor air quality and the need for enhanced air purification. Alternatively, if the user's sensitivity to airborne particulate matter is at the highest level, it indicates that the user is highly sensitive to airborne particulate matter. In both cases, the air intake parameters of the air purifier can be determined as the second air intake parameters. This means adjusting the air intake area and angle to the second air intake angle. For example, the second air intake area can be full air intake, and the second air intake angle can be 50-70 degrees.

[0112] In this embodiment, by accurately determining the air intake parameters of the air purifier based on the concentration of airborne particulate matter and the user's sensitivity to airborne particulate matter, the air purifier can flexibly adjust its operating parameters according to the actual situation in different scenarios, thereby better meeting the user's air purification needs and improving the overall performance and reliability of the air purifier.

[0113] In an exemplary embodiment, the method further includes: at a preset time point, controlling an air purifier to enter a preset working area, obtaining the electromagnetic field strength within the preset working area, and pushing an alarm message to the user if the electromagnetic field strength is greater than a preset electromagnetic field strength threshold.

[0114] The preset time point is a specific moment pre-set to trigger the air purifier to perform electromagnetic field monitoring tasks, based on user habits, device operating cycles, or environmental monitoring needs. The preset working area refers to the specific spatial range that the air purifier needs to move to or cover. For example, at 22:00 every day, the air purifier can be controlled to enter the user's bedroom and automatically activate the electromagnetic field monitoring module to monitor the electromagnetic field strength in the bedroom. Electromagnetic field strength is used to characterize the strength of the electromagnetic field in a space, reflecting the magnitude of electromagnetic radiation in that area. Alarm information is a warning signal issued to the user in the form of sound, light, vibration, or text. The alarm information may include the electromagnetic field strength value, the degree of exceeding the standard, risk warnings, and suggested measures, and can be pushed through the air purifier's speaker, indicator light, or associated mobile terminal (such as the user's mobile phone).

[0115] For example, a user can set their sleep time via a mobile terminal associated with the air purifier, such as an app on their phone. This could be set to 10:00 PM every night. Upon reaching this time, the air purifier will enter the bedroom (the preset work area) and activate its built-in electromagnetic field monitor. If the detected electromagnetic field strength exceeds 10 microtesla, it indicates that the user may have placed electronic devices close to the bed. In this case, the air purifier will send an alarm message. For instance, it might emit a beeping sound or voice alarm through the air purifier's speaker, while an indicator light flashes red. If the air purifier is linked to the user's mobile terminal (such as a phone), it can also send a text alarm message to the user's mobile terminal via its wireless communication module. This message might include the specific exceeding value and safety recommendations, such as, "The current electromagnetic field strength is 2.5 microtesla, exceeding the safety threshold of 1.0 microtesla. Please place electronic devices away from the bedroom."

[0116] In this embodiment, by actively monitoring the electromagnetic field strength of the working area at regular intervals, real-time early warning of indoor electromagnetic radiation risks is achieved. This breaks through the traditional single protection mode of air purifiers that only targets air quality, and can help users discover potential electromagnetic radiation hazards in advance, thereby improving the functionality of air purifiers and user satisfaction.

[0117] To provide a clearer explanation of the air purifier control method provided in this application, a detailed embodiment and accompanying drawings are provided below. Figure 7The detailed implementation includes the following steps:

[0118] S701, in response to the user's health monitoring data sent by the wearable device, collects the air particulate matter concentration at the target location, as well as the user's image and sound data.

[0119] S702: If the average heart rate is greater than a preset heart rate threshold and the average number of steps is greater than a preset step threshold, the user is determined to be in the first level of fatigue. If the average heart rate is greater than a preset heart rate threshold or the average number of steps is greater than a preset step threshold, the user is determined to be in the second level of fatigue. If the average heart rate is less than or equal to a preset heart rate threshold and the average number of steps is less than or equal to a preset step threshold, the user is determined to be in the third level of fatigue.

[0120] S703 determines whether a user has an allergic reaction based on the user's image and sound data.

[0121] S704: If a user experiences an allergic reaction, the user's sensitivity to airborne particulate matter is determined to be at the first level of sensitivity; if the user does not experience an allergic reaction, the user's sensitivity to airborne particulate matter is determined to be at the second level of sensitivity.

[0122] S705 determines the air purifier's fan speed based on the user's fatigue level. The fan speed is positively correlated with the fatigue level. When the user's fatigue level is greater than a preset fatigue level threshold and the air particulate matter concentration is less than or equal to a preset concentration threshold, the negative ion working mode of the air purifier is activated.

[0123] S706, when the concentration of air particulate matter is within a preset concentration range and the user's sensitivity to air particulate matter is at the second level of sensitivity, the air intake parameter of the air purifier is determined as the first air intake parameter; when the concentration of air particulate matter exceeds the preset concentration range or the user's sensitivity to air particulate matter is at the first level of sensitivity, the air intake parameter of the air purifier is determined as the second air intake parameter.

[0124] S707 controls the air purifier's operation in its working mode and with its operating parameters.
