[0002] Formaldehyde (HCHO) is a common volatile organic compound in indoor air, which seriously endangers human health. In order to reduce formaldehyde and ensure air quality, people usually use air purifiers to remove formaldehyde and other pollutants. Among them, most of the air purifier filters on the market are carbon cloth structures, but carbon cloth is easy to breed bacteria during use in a humid environment, which in turn pollutes the purified air and reduces the purification efficiency. Moreover, with the use of the filter, the activated carbon in the carbon cloth will also reduce its service life as the use time increases, further leading to a decrease in purification efficiency.

[0003] At present, the common practice is to remove the filter in time for replacement, and use a new activated carbon filter for subsequent air purification. However, due to the different filter settings of different air purifiers, the method of removing and replacing the filter is more troublesome, and it will also interrupt the working process of the air purifier and reduce the working efficiency.

At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0062] The air purifier control method provided in the embodiment of the present application can be applied to the air purifier as shown in Figure 1. In one embodiment, the air purifier includes a humidity detection device 102, a purification body 104, a filter 106, a cleaning device 108 and a controller 110, the filter 106 is arranged on the purification body 104, the humidity detection device 102 and the cleaning device 108 are both arranged on the filter 106, and the humidity detection device 102, the purification body 104 and the cleaning device 108 are all connected to the controller 110.

[0063] Among them, the purification body 104 is a device that can work with the filter 106 to purify the air, and its shape and material are not limited. The purification body 104 can be provided with an air inlet and an air outlet on the surface, and the air can enter the purification body 104 from the air inlet and release the purified air through the air outlet. The filter 106 can be arranged at a position corresponding to the air inlet in the purification body 104, and can filter the air entering the purification body 104, and filter out dust, pollutants, germs and harmful gases such as formaldehyde. The filter 106 can be arranged on the periphery of one side of the purification body 104, or on the periphery of multiple sides of the purification body 104, and can also be arranged in the cavity of air circulation inside the purification body 104. Further, the filter 106 can not only be arranged at a position corresponding to the air inlet in the purification body 104, but also can be arranged at a position corresponding to the air outlet in the purification body 104, and the purified air can be filtered again to ensure the air purification effect.

[0064] The filter 106 may include a carbon cloth, in which activated carbon is provided, which can absorb harmful components such as formaldehyde in the air and can be used to treat formaldehyde pollution. However, the carbon cloth is prone to breed bacteria in an environment with changing humidity, causing the filter 106 to produce odor, weakening the air purification effect and reducing the user experience. For example, harmful bacteria such as Gram-negative Escherichia coli, Gram-positive Bacillus subtilis and Mycobacterium smegmatis have different survival abilities under different relative humidity conditions, which increase with the increase of relative humidity, and the more drastic the change in humidity, the stronger the activity.

[0065] The humidity detection device 102 can detect the humidity data of the environment in which the air purifier is located, and transmit it to the controller 110. When the humidity detection device 102 is set on the filter 106, it can detect the humidity data on the filter 106, and transmit the detected humidity data to the connected controller 110, so that the controller 110 can monitor the humidity of the environment in which the air purifier is located, and control the cleaning device 108 to sterilize the filter 106 according to the air purifier control method provided in this application, so as to ensure the purification efficiency of the filter 106, and then ensure the purification efficiency of the air purifier.

[0066] The cleaning device 108 can sterilize the filter 106 and kill bacteria on the filter 106. Optionally, the cleaning device 108 can be an ultraviolet lamp that sterilizes by emitting ultraviolet rays. There can be multiple ultraviolet lamps, and it is necessary to ensure that the emitted ultraviolet rays can cover the entire filter 106.

[0067] The cleaning device 108 can also be other devices. In an exemplary embodiment, the cleaning device 108 is a microwave generator. Since the adsorption effect of activated carbon on formaldehyde is limited, that is, the activated carbon has a service life limit, as the usage time accumulates, the adsorption effect of activated carbon on formaldehyde becomes worse and worse until it fails. The microwave generator can generate microwaves, and heat and dry the activated carbon, remove adsorbents and activate it through microwave radiation regeneration. It has the advantages of reaction time period, small loss of activated carbon, high regeneration efficiency and developed regeneration micropores. Therefore, the controller 110 controls the microwave generator to generate microwaves, which can not only sterilize the bacteria on the filter 106, but also regenerate the activated carbon, extend the service life of the activated carbon, reduce the frequency of replacing the filter 106, and ensure the purification efficiency of the air purifier.

[0068] In an exemplary embodiment, as shown in FIG. 2 , an air purifier control method is provided, which is described by taking the method applied to the controller 110 in FIG. 1 as an example, and includes the following steps 202 to 206 .

[0069] Step 202, obtaining humidity data of the environment in which the air purifier is located.

[0070] The humidity data of the environment in which the air purifier is located is detected by the humidity detection device and transmitted to the controller. The humidity detection device can be arranged inside the air purifier to detect the humidity data inside the air purifier, or it can be arranged outside the air purifier to detect the humidity data outside the air purifier. Since the humidity detection device is arranged on the filter, whether it is the humidity data inside the air purifier or the humidity data outside the air purifier, it belongs to the humidity data of the environment in which the air purifier is located.

[0071] The controller can obtain humidity data detected by the humidity detection device. Specifically, the controller can control the working state of the humidity detection device. When the controller controls the humidity detection device to start, the humidity data of the environment where the air purifier is located is obtained. Alternatively, the humidity detection device and the air purifier can be started synchronously, and the controller only obtains humidity data from the humidity detection device when humidity data is required.

[0072] Optionally, there may be multiple humidity detection devices, which are respectively arranged at different positions of the filter. Then the controller can obtain multiple relative humidities and obtain humidity data of the environment where the air purifier is located by taking the median, calculating the variance, taking the average, and fitting the data.

[0073] Step 204: determining a humidity change index within a preset period according to the humidity data.

[0074] Specifically, the controller continuously acquires humidity data, and when the time span of the continuously acquired humidity data reaches a set time, the humidity change index is determined according to the humidity data within the set time. The set time is a preset period, that is, when the acquisition time of the humidity data reaches the preset period, the humidity change index can be determined. Optionally, the controller can divide the humidity data into preset periods from the time dimension according to the different acquisition times, and analyze the humidity data divided into the same preset period from the perspective of numerical value to obtain the humidity change index.

[0075] The controller analyzes the humidity data within a preset period, analyzes the humidity data from the numerical value, and obtains the humidity change index according to the numerical change of the humidity data within the preset period. Furthermore, the preset period can be set according to actual needs, which can be specified by the user or obtained by analyzing the historical operation data of the air purifier. For example, a preset period of one day, one week or one month. When the preset period is one week, the controller controls the humidity sensor to work for at least one week before executing step 204. That is, the time span of the humidity data obtained by the controller cannot be less than the time span of the preset period, and the humidity data that does not meet the preset period is regarded as invalid data. At the same time, if the duration of the controller obtaining the humidity data is greater than the preset period, the humidity data of a preset period is filtered from the current time forward, and the humidity change index is determined by the filtered humidity data.

[0076] In an exemplary embodiment, as shown in FIG. 3 , step 204 includes steps 302 to 306 .

[0077] Step 302, obtaining humidity data within a preset period.

[0078] Specifically, the controller selects humidity data within a preset period from multiple humidity data, and marks it as available data independently of other humidity data. The humidity data involved in the subsequent steps will be processed as the humidity data marked as available data. Among them, the humidity data within the preset period closest to the current time is preferentially selected and marked as available data. For example, when the preset period is one week, and the humidity data includes two weeks of humidity data, the humidity data of the week close to the current time is used as the humidity data within the preset period. If the preset period is one week, but the humidity data is less than one week, there is no humidity data within the preset period, and it is necessary to wait until the humidity data is sufficient for one week before the controller obtains the humidity data within the preset period.

[0079] Step 304: determine the humidity upper limit value and the humidity lower limit value within the cycle from the humidity data within the preset cycle.

[0080] Specifically, after determining the humidity data within the preset period, the controller compares the humidity data within the preset period in order to determine the humidity upper limit value and the humidity lower limit value within the period. Among the humidity data within the preset period, the humidity data with the largest humidity value is the humidity upper limit value within the period, and the humidity data with the smallest humidity value is the humidity lower limit value within the period.

[0081] Step 306, determining a humidity change index within a preset period according to the humidity upper limit value within the period and the humidity lower limit value within the period.

[0082] The controller stores an index classification basis, and the index classification basis can determine the humidity change index according to the difference between the humidity upper limit value within the cycle and the humidity lower limit value within the cycle. Specifically, the controller first compares the humidity upper limit value within the cycle with the humidity lower limit value within the cycle to obtain the difference between the two, and then determines the humidity change index corresponding to the difference from multiple humidity change indicators according to the index classification basis, so as to determine the humidity change index within the preset cycle.

[0083] Exemplarily, the humidity change index includes a first index, a second index, and a third index, and the index division basis includes: if the difference between the humidity upper limit value and the humidity lower limit value within the period meets the first setting condition, the humidity change index within the preset period can be determined as the first index; if the difference between the humidity upper limit value and the humidity lower limit value within the period meets the second setting condition, the humidity change index within the preset period can be determined as the second index; if the difference between the humidity upper limit value and the humidity lower limit value within the period meets the third setting condition, the humidity change index within the preset period can be determined as the third index. Among them, the first setting condition can be that the difference is less than or equal to 10%, the second setting condition can be that the difference is greater than 10% and less than or equal to 40%, and the third setting condition can be that the difference is greater than 40% and less than or equal to 80%. Similarly, the humidity change value represented by the first index is less than the humidity change value represented by the second index, and the humidity change value represented by the second index is less than the humidity change value represented by the third index. That is, as the difference between the humidity upper limit value and the humidity lower limit value within the period increases, the greater the humidity change, the greater the humidity change value represented by the corresponding index.

[0084] In this embodiment, different indicators are determined by dividing the difference between the upper limit value of humidity within the cycle and the lower limit value of humidity within the cycle to facilitate the completion of subsequent steps and accurately control the cleaning device to sterilize the filter of the air purifier.

[0085] Step 206, based on the filter usage time and humidity change index of the air purifier, control the cleaning device of the air purifier to operate.

[0086] Among them, the cleaning device is used to sterilize the filter of the air purifier. The filter is a structure in the air purifier that purifies dust, formaldehyde and other substances. It is easy to produce bacteria during use, and the cleaning device can kill the bacteria that breed in the filter of the air purifier to achieve sterilization, and further reduce the odor generation of the filter. The filter usage time characterizes the length of time from the start of the filter to the current time. Usually, the filter includes activated carbon, and the adsorption capacity and activity retention effect of the activated carbon are time-sensitive, which decreases with the increase in usage time, resulting in a decrease in the filtering and purification effect. Therefore, the activated carbon in the filter is usually set with a service life to limit its usage time.

[0087] Specifically, after obtaining the humidity change index, the controller combines the use time of the air purifier filter and preliminarily determines the working mode of the cleaning device according to the humidity change index, and then further adjusts the working mode of the cleaning device in combination with the use time of the filter. After determining the further adjusted working mode of the cleaning device, the controller can control the cleaning device of the air purifier to work according to the working mode to achieve sterilization and cleaning of the filter.

[0088] The above-mentioned air purifier control method includes obtaining humidity data of the environment in which the air purifier is located, determining the humidity change index within a preset period based on the humidity data, and controlling the operation of the cleaning device of the air purifier based on the usage time and humidity change index of the filter of the air purifier. Among them, the cleaning device is used to sterilize the filter of the air purifier. By combining the usage time and humidity change of the filter of the air purifier, the cleaning device is controlled to sterilize and clean the filter, which is conducive to ensuring the purification effect of the filter of the air purifier, and then ensuring the purification efficiency of the air purifier.

[0089] In an exemplary embodiment, as shown in FIG. 4 , step 206 includes steps 402 to 406 .

[0090] Step 402: Determine the activation frequency of the cleaning device of the air purifier based on the humidity change index.

[0091] Specifically, the controller stores a plurality of start-up frequencies of the cleaning device, and different start-up frequencies correspond to different humidity change indicators. The controller determines the start-up frequency corresponding to the currently determined humidity change indicator from the plurality of start-up frequencies according to the determined humidity change indicator, and uses the start-up frequency as the start-up frequency of the cleaning device of the air purifier.

[0092] Step 404, based on the usage time of the filter of the air purifier, determine the target startup time from the startup time corresponding to the startup frequency.

[0093] Each startup frequency corresponds to more than two startup durations, and different startup frequencies may correspond to different startup durations. After determining the startup frequency of the cleaning device, the controller selects the startup duration corresponding to the startup frequency as the target startup duration based on the filter usage time of the air purifier, thereby determining the startup frequency of the cleaning device during work and the working duration of each startup.

[0094] Specifically, when the filter usage time is different, the startup time corresponding to the startup frequency in the cleaning device also changes accordingly to ensure that the startup time of the cleaning device matches the usage time of the filter, that is, the activity of the activated carbon in the filter. Furthermore, the controller stores multiple startup times. On the basis of the same startup frequency, different startup times corresponding to the startup frequency correspond to different filter usage times. As the filter usage time increases, the startup time also increases. Optionally, at different startup frequencies, the same filter usage time may correspond to different startup times.

[0095] Step 406 , controlling the operation of the cleaning device according to the start-up frequency and the target start-up duration.

[0096] Specifically, the controller determines the sterilization logic required for the filter of the air purifier under the current situation, that is, the operation control requirements of the cleaning device, including the start-up frequency and the target start-up time, based on the humidity change index and the filter start-up time, through the execution of the above steps. Based on the determined start-up frequency and start-up time, the controller controls the operation of the cleaning device, and the cleaning device sterilizes the filter of the air purifier.

[0097] In this embodiment, by determining the start-up frequency according to the humidity change index, and then determining the target start-up duration based on the filter usage time, the start-up frequency and target start-up duration of the cleaning device can be determined in turn according to the humidity and the filter usage. This is conducive to accurate sterilization for different environments and usage conditions. Furthermore, when the cleaning device is a microwave generator, the activated carbon in the filter can also be regenerated, which is conducive to ensuring the convenience and purification stability of the air purifier.

[0098] In an exemplary embodiment, as shown in FIG. 5 , step 404 includes steps 502 to 506 .

[0099] Step 502, determining the filter availability based on the preset service life of the filter and the usage time of the filter of the air purifier.

[0100] Among them, during the design and manufacturing process of the filter, a preset service life of the filter is usually set. The preset service life of the filter is related to the structure of the filter and the amount of activated carbon contained in the filter. It is a set value and can be reflected in the model parameters of the air purifier.

[0101] Specifically, when the controller is connected to the purification body, it can determine the preset service life of the filter corresponding to the filter of the air purifier according to the model parameters of the purification body. The preset service life of the filter of the air purifier can also be pre-stored in the controller. With the activation of the air purifier, the usage time of the filter of the air purifier is calculated according to the corresponding matching of the startup time of the air purifier. The controller compares and calculates the preset service life of the filter and the usage time of the filter to obtain the filter availability.

[0102] Furthermore, the filter availability can be calculated by subtracting the filter usage time from the preset service life of the filter to obtain the difference between the two, and then dividing the difference by the preset service life of the filter to obtain the filter availability.

[0103] Optionally, the filter may be replaced during the use of the air purifier. In this case, the startup time of the air purifier cannot be equal to the filter usage time of the air purifier. The controller is required to detect whether the filter is installed in place and reset the filter usage time when the filter is removed several times, and restart the timing according to the startup time of the air purifier.

[0104] Step 504: when the filter availability is less than the regeneration trigger value, determine a first preselected duration as a target startup duration from the startup durations corresponding to the startup frequency.

[0105] Step 506 : when the filter availability is greater than or equal to the regeneration trigger value, determine a second preselected duration as the target startup duration from the startup durations corresponding to the startup frequency.

[0106] The first preselected time is greater than the second preselected time. The regeneration trigger value is a value stored in the controller based on the preset service life of the filter, which represents a certain value of the filter availability. Exemplarily, the regeneration trigger value can be 80%. When the filter availability is lower than the regeneration trigger value, it indicates that the activity of the activated carbon in the filter is insufficient, the adsorption is reduced, and the purification efficiency is reduced.

[0107] After the controller determines the start-up frequency and calculates the filter availability, the start-up duration corresponding to the start-up frequency is first called, so as to determine the target start-up duration from the called start-up duration according to the filter availability. Among them, multiple start-up durations are stored in the controller, each of which corresponds to a start-up frequency, and different start-up durations can correspond to the same start-up frequency. In the case that the number of start-up durations corresponding to the start-up frequency is two, the two start-up durations are marked as the first pre-selected duration and the second pre-selected duration. The first pre-selected duration is greater than the second pre-selected duration.

[0108] The controller compares the obtained filter availability with the regeneration trigger value, and selects the first preselected duration or the second preselected duration as the target startup duration according to the size of the comparison. Specifically, if the filter availability is less than the regeneration trigger value, it means that the current filter has been used for a long time, the activated carbon is less active, and there is a risk of reduced purification efficiency. Therefore, it is necessary to use the first preselected duration corresponding to the determined startup frequency as the target startup duration of the cleaning device. By starting the cleaning device for a longer time, the activated carbon in the filter can be regenerated while the filter is sterilized to ensure purification efficiency.

[0109] If the filter availability is greater than or equal to the regeneration trigger value, it indicates that the current filter usage time is short, the activated carbon activity is high, and the purification efficiency can be maintained at a high level. Therefore, the second preselected time corresponding to the determined start-up frequency can be used as the target start-up time of the cleaning device. By starting the cleaning device for a shorter time, the filter can be sterilized, bacterial contamination can be reduced, and purification efficiency can be guaranteed.

[0110] In this embodiment, the filter availability is determined based on the preset service life of the filter and the usage time of the filter, and based on different filter availability, in the pre-selected time corresponding to the same startup frequency, the pre-selected time that matches the filter availability is determined as the target startup time of the cleaning device. This ensures the simultaneous realization of the filter sterilization function and the activated carbon regeneration function of the filter of the cleaning device, fully considers the optimization of the filter, reduces the need to disassemble the filter, and improves the convenience and purification efficiency of the air purifier.

[0111] In an exemplary embodiment, the humidity change index includes a first index, a second index, and a third index. The humidity change value represented by the first index is less than the humidity change value represented by the second index, and the humidity change value represented by the second index is less than the humidity change value represented by the third index. As shown in FIG. 6 , step 402 includes steps 602 to 606.

[0112] Step 602: When the humidity change indicator is the first indicator, determine that the start-up frequency of the cleaning device is the first frequency.

[0113] Step 604: when the humidity change index is the second index, determine the start-up frequency of the cleaning device to be the second frequency.

[0114] Step 606: When the humidity change index is the third index, determine that the start-up frequency of the cleaning device is the third frequency.

[0115] The first frequency is lower than the second frequency, the second frequency is lower than the third frequency, the humidity change value represented by the first indicator is smaller than the humidity change value represented by the second indicator, and the humidity change value represented by the second indicator is smaller than the humidity change value represented by the third indicator.

[0116] Specifically, the first frequency, the second frequency and the third frequency are different start-up frequencies of the cleaning device, respectively, and have a corresponding relationship with the first indicator, the second indicator and the third indicator. The first frequency, the second frequency and the third frequency can be set according to actual needs, such as by the user, or by setting a default value at the factory, or by analyzing big data or related data. For example, the first frequency is started once every 8 hours; the second frequency is started once every 4 hours; and the third frequency is started once every 2 hours.

[0117] Exemplarily, when the humidity change index is the first index, that is, the humidity change value is less than or equal to 10%, the controller determines that the start-up frequency of the cleaning device is the first frequency, which may be started once every 8 hours. When the humidity change index is the second index, that is, the humidity change value is greater than 10% and less than or equal to 40%, the controller determines that the start-up frequency of the cleaning device is the second frequency, which may be started once every 4 hours. When the humidity change index is the third index, that is, the humidity change value is greater than 40% and less than 80%, the controller determines that the start-up frequency of the cleaning device is the third frequency, which may be started once every 2 hours.

[0118] Further, when the humidity change index is the first index, and the controller determines that the start-up frequency of the cleaning device is the first frequency, the first preselected time length corresponding to the first frequency is 0.5 hours, and the second preselected time length corresponding to the first frequency is 0.2 hours. When the humidity change index is the second index, and the controller determines that the start-up frequency of the cleaning device is the second frequency, the first preselected time length corresponding to the second frequency is 1 hour, and the second preselected time length corresponding to the second frequency is 0.5 hours. When the humidity change index is the third index, and the controller determines that the start-up frequency of the cleaning device is the third frequency, the first preselected time length corresponding to the third frequency is 1.5 hours, and the second preselected time length corresponding to the third frequency is 1 hour.

[0119] In this embodiment, by determining different starting frequencies of the cleaning device based on different humidity change indicators, a strong correlation between the purification function of the cleaning device and the humidity change index is ensured, and the influence of humidity data on the growth of bacteria on the filter is fully considered, so that the cleaning device of the air purifier can accurately sterilize the filter.

[0120] In an exemplary embodiment, the humidity change index further includes a fourth index, and the humidity change value of the fourth index is greater than the humidity change value of the third index. As shown in FIG7 , after step 204 , the air purifier control method further includes step 702 : when the humidity change index is the fourth index, controlling the cleaning device to continuously start.

[0121] Specifically, the humidity change index may also include a fourth indicator, and the humidity change value of the fourth indicator is greater than the humidity change value of the third indicator, for example, the humidity change value corresponding to the fourth indicator is greater than 80%. Then, when the humidity change index is the fourth indicator, it indicates that the humidity of the environment in which the air purifier is located is too high, and in an environment with too high humidity, the growth rate of bacteria is at a high level, and it is easy to breed a large number of bacteria in a short time, affecting the purification efficiency. In this case, there is no need to consider the impact of the filter usage time on the regeneration of the filter activated carbon. It is only necessary to continuously sterilize the filter while ensuring the activity of the activated carbon. Therefore, the controller can control the cleaning device to start continuously, continuously sterilize the filter, and at the same time ensure the activity of the activated carbon in the filter.

[0122] Furthermore, when the cleaning device is continuously started, there is no need to determine the start-up time of the cleaning device of the air purifier, nor is it necessary to adjust it according to the use time of the filter of the air purifier. The cleaning device can be directly controlled to run continuously.

[0123] In this embodiment, by setting different humidity change indicators, the conditions of the environment in which the air purifier is located are fully and comprehensively considered, and the filter is accurately sterilized to ensure the purification efficiency and reliable operation of the air purifier.

[0124] Based on the same technical concept, the present application also provides an air purifier, as shown in Figure 1, the air purifier includes a humidity detection device 102, a purification body 104, a filter 106, a cleaning device 108 and a controller 110, the filter 106 is arranged on the purification body 104, the humidity detection device 102 and the cleaning device 108 are both arranged on the filter 106, and the humidity detection device 102, the purification body 104 and the cleaning device 108 are all connected to the controller 110.

[0125] Among them, the purification body 104 is a device that can work with the filter 106 to purify the air, and its shape and material are not limited. The purification body 104 can be provided with an air inlet and an air outlet on the surface, and the air can enter the purification body 104 from the air inlet and release the purified air through the air outlet. The filter 106 can be arranged at a position corresponding to the air inlet in the purification body 104, and can filter the air entering the purification body 104, and filter out dust, pollutants, germs and harmful gases such as formaldehyde. The filter 106 can be arranged on the periphery of one side of the purification body 104, or on the periphery of multiple sides of the purification body 104, and can also be arranged in the cavity of air circulation inside the purification body 104. Further, the filter 106 can not only be arranged at a position corresponding to the air inlet in the purification body 104, but also can be arranged at a position corresponding to the air outlet in the purification body 104, and the purified air can be filtered again to ensure the air purification effect.

[0126] The filter 106 may include a carbon cloth, in which activated carbon is provided, which can absorb harmful components such as formaldehyde in the air and can be used to treat formaldehyde pollution. However, the carbon cloth is prone to breed bacteria in an environment with changing humidity, causing the filter 106 to produce odor, weakening the air purification effect and reducing the user experience. For example, harmful bacteria such as Gram-negative Escherichia coli, Gram-positive Bacillus subtilis and Mycobacterium smegmatis have different survival abilities under different relative humidity conditions, which increase with the increase of relative humidity, and the more drastic the change in humidity, the stronger the activity.

[0127] The humidity detection device 102 can detect the humidity data of the environment in which the air purifier is located, and transmit it to the controller 110. When the humidity detection device 102 is set on the filter 106, it can detect the humidity data on the filter 106, and transmit the detected humidity data to the connected controller 110, so that the controller 110 can monitor the humidity of the environment in which the air purifier is located, and control the cleaning device 108 to sterilize the filter 106 according to the air purifier control method provided in this application, so as to ensure the purification efficiency of the filter 106, and then ensure the purification efficiency of the air purifier.

[0128] The cleaning device 108 can sterilize the filter 106 and kill bacteria on the filter 106. Optionally, the cleaning device 108 can be an ultraviolet lamp that sterilizes by emitting ultraviolet rays. There can be multiple ultraviolet lamps, and it is necessary to ensure that the emitted ultraviolet rays can cover the entire filter 106.

[0129] The cleaning device 108 can also be other devices. In an exemplary embodiment, the cleaning device 108 is a microwave generator. Since the adsorption effect of activated carbon on formaldehyde is limited, that is, the activated carbon has a service life limit, as the usage time accumulates, the adsorption effect of activated carbon on formaldehyde becomes worse and worse until it fails. The microwave generator can generate microwaves, and heat and dry the activated carbon, remove adsorbents and activate it through microwave radiation regeneration. It has the advantages of reaction time period, small loss of activated carbon, high regeneration efficiency and developed regeneration micropores. Therefore, the controller 110 controls the microwave generator to generate microwaves, which can not only sterilize the bacteria on the filter 106, but also regenerate the activated carbon, extend the service life of the activated carbon, reduce the frequency of replacing the filter 106, and ensure the purification efficiency of the air purifier.

[0130] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0131] In one embodiment, the air purifier includes a humidity detection device, a purification body, a filter, a cleaning device and a controller, wherein the filter is arranged on the purification body, the humidity detection device and the cleaning device are both arranged on the filter, and the humidity detection device, the purification body and the cleaning device are all connected to the controller. The filter includes activated carbon, and the cleaning device is a microwave generator capable of regenerating the activated carbon.

[0132] The humidity detection device detects the air humidity (humidity data) of the filter in the air purifier in real time and sends it to the controller. The controller connects to the purification body to obtain the filter usage time and calculates the remaining life of the filter (filter availability). The preset cycle set in the controller is one week. The controller analyzes the air humidity and filter usage time:

[0133] If the air humidity changes by ≤10% within a week, the microwave generator will be started every 8 hours. When the remaining life of the filter is less than 80%, the microwave generator will work for 0.5 hours each time. When the remaining life of the filter is ≥80%, the microwave generator will work for 0.2 hours each time. This logic is used to kill bacteria in the filter.

[0134] When the air humidity changes between 10%-40% within a week, the ozone generator is started every 4 hours instead of every 8 hours. When the remaining life of the filter is less than 80%, the microwave generator works for 1 hour each time. When the remaining life of the filter is ≥80%, the microwave generator works for 0.5 hours each time. This logic is used to kill bacteria in the filter.

[0135] When the air humidity changes between 40%-80% within a week, the ozone generator is started every 2 hours instead of every 4 hours. When the remaining life of the filter is less than 80%, the microwave generator works for 1.5 hours each time. When the remaining life of the filter is ≥80%, the microwave generator works for 1 hour each time. This logic is used to kill bacteria in the filter.

[0136] When the air humidity changes by more than 80% within a week, the ozone generator is started up once every 1 hour instead of every 2 hours. At this time, the air humidity changes greatly and bacteria growth will be obvious. The microwave generator works for 1 hour each time and the continuous working time is 1 hour, that is, the microwave generator runs continuously. This logic is used to kill the bacteria in the filter.

[0137] In this embodiment, the influence of environmental humidity on the bacterial generation rate in the filter is fully considered, and the purification efficiency of the filter is guaranteed by combining the filter life, and the operation of the microwave generator is controlled by combining the humidity change index and the filter usage time, and the filter is accurately sterilized according to different working conditions, and the adsorption capacity of the activated carbon of the filter to formaldehyde is maintained. It can effectively ensure the sterilization effect and the purification efficiency of the air purifier.
