[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 arrange air purifiers to remove pollutants such as formaldehyde. Among them, most of the filter screens of air purifiers on the market are carbon cloth structures, but the carbon cloth is prone to bacterial growth in a humid environment during use, thereby polluting the purified air and reducing the purification efficiency. Moreover, as the filter screen is used, the active carbon in the carbon cloth will also reduce the service life with the increase of the use time, further leading to the decrease of the purification efficiency.

[0003] At present, the common practice is to disassemble and replace the filter screen in time to use new active carbon filter screen to achieve subsequent air purification. However, since the filter screen setting structures of different air purifiers are different, the way of disassembling and replacing the filter screen is more troublesome, and it will also interrupt the working process of the air purifier, reducing the working efficiency.

[0057] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0058] It can be understood that the terms "first", "second" and the like used in the present application can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. For example, without departing from the scope of the present application, the first resistor can be referred to as the second resistor, and similarly, the second resistor can be referred to as the first resistor. The first resistor and the second resistor are both resistors, but they are not the same resistor.

[0059] It can be understood that "connection" in the following embodiments, if the circuits, modules, units and the like connected to each other have the transmission of electrical signals or data, should be understood as "electrically connected", "communicatively connected" and the like.

[0060] As used herein, the singular forms "a", "an" and "the" can include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "comprise / comprising" or "have / having" specifies the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but does not exclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in the specification includes any and all combinations of the related listed items.

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

[0062] The air purifier control method provided by the embodiments 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 screen 106, a cleaning device 108, and a controller 110. The filter screen 106 is arranged in the purification body 104, the humidity detection device 102 and the cleaning device 108 are arranged in the filter screen 106, and the humidity detection device 102, the purification body 104 and the cleaning device 108 are connected to the controller 110.

[0063] The purification body 104 is a device capable of working with the filter screen 106 to purify air, and the shape and material of the purification body 104 are not limited. The purification body 104 can be provided with an air inlet and an air outlet on the surface. Air can enter the purification body 104 from the air inlet and release purified air through the air outlet. The filter screen 106 can be arranged in the purification body 104 corresponding to the air inlet, capable of filtering the air entering the purification body 104, filtering out dust, pollutants, bacteria and harmful gases such as formaldehyde. The filter screen 106 can be arranged on one side of the periphery of the purification body 104, or on multiple sides of the periphery of the purification body 104, or in the air flow cavity inside the purification body 104. Further, the filter screen 106 can be arranged not only in the purification body 104 corresponding to the air inlet, but also in the purification body 104 corresponding to the air outlet, to filter the purified air again and ensure the air purification effect.

[0064] The filter screen 106 can include carbon cloth, which is provided with activated carbon capable of adsorbing harmful components such as formaldehyde in the air and can be used to control formaldehyde pollution. However, carbon cloth is prone to bacterial growth in an environment with changing humidity, resulting in odor of the filter screen 106, weakening the air purification effect and reducing 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 where the air purifier is located and transmit it to the controller 110. When the humidity detection device 102 is arranged on the filter screen 106, it can detect the humidity data on the filter screen 106 and transmit the detected humidity data to the connected controller 110, so that the controller 110 can monitor the humidity of the environment where the air purifier is located, and control the sterilization of the filter screen 106 by the cleaning device 108 according to the air purifier control method provided by the present application, to ensure the purification efficiency of the filter screen 106 and further ensure the purification efficiency of the air purifier.

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

[0067] The cleaning device 108 can also be other devices. In one exemplary embodiment, the cleaning device 108 is a microwave generator. Since the adsorption effect of activated carbon on formaldehyde is limited, meaning activated carbon has a limited lifespan, its adsorption effect on formaldehyde decreases with accumulated use until it becomes ineffective. A microwave generator can generate microwaves, using microwave radiation to regenerate the activated carbon, heating and drying it, removing adsorbates, and activating it. This method has advantages such as short reaction time, minimal activated carbon loss, high regeneration efficiency, and well-developed micropores. Therefore, the controller 110 controls the microwave generator to generate microwaves, which not only sterilizes bacteria on the filter 106 but also regenerates the activated carbon, extending its lifespan and reducing the frequency of filter 106 replacement while ensuring the air purifier's purification efficiency.

[0068] In one exemplary embodiment, such as Figure 2 As shown, an air purifier control method is provided, which is applied to... Figure 1 The following steps are used as an example to illustrate the process of controller 110, including steps 202 to 206.

[0069] Step 202: Obtain humidity data of the environment where the air purifier is located.

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

[0071] The controller can acquire humidity data detected by the humidity detection device. Specifically, the controller can control the working status of the humidity detection device. When the controller controls the humidity detection device to start, it acquires the humidity data of the environment where the air purifier is located. Alternatively, the humidity detection device and the air purifier can start working synchronously, and the controller only acquires humidity data from the humidity detection device when required.

[0072] Optionally, multiple humidity detection devices can be installed at different locations on the filter. The controller can then acquire multiple relative humidity values ​​and obtain humidity data for the environment where the air purifier is located by taking the median, calculating the variance, taking the average, and data fitting.

[0073] Step 204: Determine the humidity change index within the preset period based on the humidity data.

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

[0075] The controller analyzes the humidity data in a preset period from the value of the humidity data, and obtains the humidity change index according to the value change of the humidity data in the preset period. Further, the preset period can be set according to actual needs, which can be specified by a user or obtained according to historical running data of the air purifier. For example, the preset period is one day, one week or one month. When the preset period is one week, the controller can execute step 204 only after the humidity sensor works for at least one week. That is, the time span of the humidity data acquired 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 acquisition time length of the humidity data by the controller is greater than the preset period, the humidity data of a preset period is filtered from the current time, and the humidity change index is determined according to the filtered humidity data.

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

[0077] Step 302, acquiring humidity data in a preset period.

[0078] Specifically, the controller filters the humidity data in the preset period from the plurality of humidity data, and marks the humidity data as available data independently of other humidity data. In the subsequent steps, the humidity data involved will be processed by taking the humidity data marked as available data as an example. Preferably, the humidity data closest to the current time in the preset period is selected as the 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 one week close to the current time is selected as the humidity data in the preset period. If the preset period is one week, but the humidity data is less than one week, there is no humidity data in the preset period, and the controller needs to acquire the humidity data in the preset period after the humidity data is sufficient for one week.

[0079] Step 304, determining an upper limit value of humidity in a period and a lower limit value of humidity in a period from the humidity data in the preset period.

[0080] Specifically, after determining the humidity data in the preset period, the controller sequentially compares the humidity data in the preset period in numerical size, and determines the upper limit value of humidity in the period and the lower limit value of humidity in the period. Among them, the humidity data with the largest humidity value in the humidity data in the preset period is the upper limit value of humidity in the period, and the humidity data with the smallest humidity value is the lower limit value of humidity in the period.

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

[0082] The controller stores an index division basis, which can determine the humidity change index according to the difference between the upper limit value of humidity in the period and the lower limit value of humidity in the period. Specifically, the controller first compares the upper limit value of humidity in the period and the lower limit value of humidity in the period to obtain the difference between them, and then determines the humidity change index corresponding to the difference from a plurality of humidity change indexes according to the index division basis, to determine the humidity change index in the preset period.

[0083] For example, 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 upper limit value of humidity in the period and the lower limit value of humidity in the period meets the first set condition, the humidity change index in the preset period can be determined as the first index; if the difference between the upper limit value of humidity in the period and the lower limit value of humidity in the period meets the second set condition, the humidity change index in the preset period can be determined as the second index; if the difference between the upper limit value of humidity in the period and the lower limit value of humidity in the period meets the third set condition, the humidity change index in the preset period can be determined as the third index. Wherein, the first set condition can be that the difference is less than or equal to 10%, the second set condition can be that the difference is greater than 10% and less than or equal to 40%, and the third set 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 upper limit value of humidity in the period and the lower limit value of humidity in the period increases, the humidity change represented by the corresponding index is greater, and the humidity change value represented by the corresponding index is greater.

[0084] In this embodiment, different indexes are determined by dividing the difference between the upper limit value of humidity in the period and the lower limit value of humidity in the period, so as to accurately control the cleaning device of the air purifier to sterilize the filter screen.

[0085] Step 206, controlling the cleaning device of the air purifier to work based on the filter screen use time length of the air purifier and the humidity change index.

[0086] The cleaning device is used to sterilize the air purifier's filter. The filter is the structure in an air purifier that purifies substances such as dust and formaldehyde. During use, bacteria can easily grow on the filter, and the cleaning device can eliminate these bacteria, achieving sterilization and further reducing odor generation. Filter usage time refers to the duration of time the filter has been in use. Filters typically contain activated carbon, but the adsorption capacity and activity retention of activated carbon are time-sensitive, decreasing with usage time and thus reducing filtration efficiency. Therefore, the activated carbon in the filter usually has a lifespan limit to restrict its use.

[0087] Specifically, after receiving the humidity change index, the controller, combined with the air purifier's filter usage time, initially determines the operating mode of the cleaning device based on the different humidity change indices. Then, considering the filter usage time, it further adjusts the operating mode of the cleaning device. Once the controller has determined the adjusted operating mode of the cleaning device, it can control the air purifier's cleaning device to operate according to that mode, achieving sterilization and cleaning of the filter.

[0088] The aforementioned air purifier control method includes acquiring humidity data of the environment in which the air purifier is located, determining humidity change indicators within a preset period based on the humidity data, and controlling the operation of the air purifier's cleaning device based on the filter usage time and humidity change indicators. The cleaning device is used to sterilize the air purifier's filter. By combining the filter usage time and humidity changes to control the cleaning device to sterilize and clean the filter, the purification effect of the air purifier's filter is ensured, thereby guaranteeing the air purifier's purification efficiency.

[0089] In one exemplary embodiment, such as Figure 4 As shown, step 206 includes steps 402 to 406.

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

[0091] Specifically, the controller stores multiple activation frequencies for the cleaning devices, with different activation frequencies corresponding to different humidity change indicators. Based on the determined humidity change indicator, the controller selects the activation frequency corresponding to the currently determined humidity change indicator from among the multiple activation frequencies and uses this activation frequency as the activation frequency of the air purifier's cleaning devices.

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

[0093] Each start-up frequency corresponds to two or more start-up durations, and different start-up frequencies can correspond to different start-up durations. After the controller determines the start-up frequency of the cleaning device, the controller selects a start-up duration corresponding to the start-up frequency as a target start-up duration according to the filter screen use duration of the air purifier, so as to determine the start-up frequency of the cleaning device in operation and the working duration of each start-up.

[0094] Specifically, when the filter screen use duration is different, the start-up duration corresponding to the start-up frequency in the cleaning device also changes, so as to match the start-up duration of the cleaning device with the use duration of the filter screen, that is, the activity of the activated carbon in the filter screen. Further, the controller stores a plurality of start-up durations. On the basis of the same start-up frequency, different start-up durations corresponding to the start-up frequency correspond to different filter screen use durations. As the filter screen use duration increases, the start-up duration also increases. Alternatively, under different start-up frequencies, the same filter screen use duration can correspond to different start-up durations.

[0095] Step 406: controlling the cleaning device to operate according to the start-up frequency and the target start-up duration.

[0096] Specifically, the controller determines the sterilization logic required by the filter screen of the air purifier under the current situation of the air purifier, that is, the operation control requirement of the cleaning device, including the start-up frequency and the target start-up duration, according to the humidity change index and the filter screen start-up duration through the execution of the above steps. The controller controls the cleaning device to operate based on the determined start-up frequency and start-up duration, and the sterilization of the filter screen of the air purifier is performed by the operation of the cleaning device.

[0097] In this embodiment, the start-up frequency is determined according to the humidity change index, and the target start-up duration is determined based on the filter screen use duration, so that the start-up frequency and the target start-up duration of the cleaning device are determined according to the humidity and the use of the filter screen in sequence. This is conducive to accurate sterilization for different environments and use conditions. Further, when the cleaning device is a microwave generating device, the activated carbon in the filter screen can be regenerated, which is conducive to ensuring the convenience and purification stability of the air purifier.

[0098] In one exemplary embodiment, as shown in Figure 5 Step 404 includes steps 502 to 506.

[0099] Step 502: determining the filter screen availability based on the filter screen preset service life and the filter screen use duration of the air purifier.

[0100] In the process of design and manufacture of the factory, the filter screen preset service life is usually set, which is related to the structure and the amount of activated carbon of the filter screen. The filter screen preset service life is a set value, which can be reflected in the model parameters of the air purifier.

[0101] Specifically, when the controller is connected to the purification body, the filter screen preset service life corresponding to the filter screen of the air purifier can be determined according to the model parameters of the purification body. Alternatively, the filter screen preset service life of the air purifier can be pre-stored in the controller. When the air purifier is started, the filter screen service time of the air purifier is calculated according to the starting time length of the air purifier. The controller compares and calculates the filter screen preset service life and the filter screen service time to obtain the filter screen availability.

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

[0103] Alternatively, during the use of the air purifier, the filter screen can be replaced. In this case, the starting time length of the air purifier cannot be equal to the filter screen service time of the air purifier, and the controller needs to detect whether the filter screen is installed in place and clear the filter screen service time when the filter screen is disassembled a certain number of times, and then start timing according to the starting time length of the air purifier.

[0104] Step 504, in the case where the filter screen availability is less than the regeneration trigger value, determining the first preselected time length as the target starting time length from the starting time length corresponding to the starting frequency.

[0105] Step 506, in the case where the filter screen availability is greater than or equal to the regeneration trigger value, determining the second preselected time length as the target starting time length from the starting time length corresponding to the starting frequency.

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

[0107] After the controller determines the starting frequency and calculates the filter screen availability, the starting time length corresponding to the starting frequency is called first, so as to determine the target starting time length from the called starting time length according to the filter screen availability. Among them, the controller stores a plurality of starting time lengths, each of which corresponds to a starting frequency. Different starting time lengths can correspond to the same starting frequency. In the case where the number of starting time lengths corresponding to the starting frequency is two, the two starting time lengths are marked as the first preselected time length and the second preselected time length. Among them, the first preselected time length is greater than the second preselected time length.

[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 start-up duration according to the comparison. Specifically, if the filter availability is less than the regeneration trigger value, it indicates that the current filter has been used for a long time and the activated carbon has low activity, and there is a risk of a decrease in purification efficiency. Therefore, the first preselected duration corresponding to the determined start-up frequency is selected as the target start-up duration of the cleaning device, and the cleaning device is started up for a long time to sterilize the filter and regenerate the activated carbon of the filter, thereby ensuring the purification efficiency.

[0109] If the filter availability is greater than or equal to the regeneration trigger value, it indicates that the current filter has been used for a short time and the activated carbon has high activity, and can maintain high purification efficiency. Therefore, the second preselected duration corresponding to the determined start-up frequency can be selected as the target start-up duration of the cleaning device, and the cleaning device is started up for a short time to sterilize the filter and reduce bacterial contamination, thereby ensuring the purification efficiency.

[0110] In this embodiment, the filter availability is determined based on the preset service life of the filter and the use duration of the filter, and based on different filter availabilities, the preselected duration corresponding to the filter availability is determined as the target start-up duration of the cleaning device in the preselected duration corresponding to the same start-up frequency, thereby ensuring the simultaneous implementation of the filter sterilization function and the activated carbon regeneration function of the cleaning device, fully considering the optimization of the filter, reducing the need to disassemble the filter, and improving the convenience and purification efficiency of the air purifier.

[0111] In one exemplary embodiment, the humidity change indicator includes a first indicator, a second indicator, and a third indicator. The first indicator represents a smaller humidity change value than the second indicator, and the second indicator represents a smaller humidity change value than the third indicator. Figure 6 As shown in FIG. 6, step 402 includes steps 602-606.

[0112] In step 602, when the humidity change indicator is the first indicator, the start-up frequency of the cleaning device is determined to be the first frequency.

[0113] In step 604, when the humidity change indicator is the second indicator, the start-up frequency of the cleaning device is determined to be the second frequency.

[0114] In step 606, when the humidity change indicator is the third indicator, the start-up frequency of the cleaning device is determined to be the third frequency.

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

[0116] Specifically, the first frequency, the second frequency and the third frequency are different starting frequencies of the cleaning device, and have a corresponding relationship with the first index, the second index and the third index. The first frequency, the second frequency and the third frequency can be set according to actual needs, for example, set by the user, or set with a default value when the product is shipped, or obtained according to big data or related data analysis. For example, the first frequency is to start once every 8 hours; the second frequency is to start once every 4 hours; and the third frequency is to start once every 2 hours.

[0117] For example, when the humidity change index is the first index, i.e., the humidity change value is less than or equal to 10%, the controller determines that the starting frequency of the cleaning device is the first frequency, which can be started once every 8 hours. When the humidity change index is the second index, i.e., the humidity change value is greater than 10% and less than or equal to 40%, the controller determines that the starting frequency of the cleaning device is the second frequency, which can be started once every 4 hours. When the humidity change index is the third index, i.e., the humidity change value is greater than 40% and less than 80%, the controller determines that the starting frequency of the cleaning device is the third frequency, which can be started once every 2 hours.

[0118] Further, when the humidity change index is the first index, the controller determines that the starting frequency of the cleaning device is the first frequency, the first preselected time corresponding to the first frequency is 0.5 hours, and the second preselected time corresponding to the first frequency is 0.2 hours. When the humidity change index is the second index, the controller determines that the starting frequency of the cleaning device is the second frequency, the first preselected time corresponding to the second frequency is 1 hour, and the second preselected time corresponding to the second frequency is 0.5 hours. When the humidity change index is the third index, the controller determines that the starting frequency of the cleaning device is the third frequency, the first preselected time corresponding to the third frequency is 1.5 hours, and the second preselected time 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 indexes, the strong correlation between the purification function of the cleaning device and the humidity change index is ensured, the influence of humidity data on the breeding of bacteria on the filter screen is fully considered, and the cleaning device of the air purifier can accurately sterilize the filter screen when sterilizing the filter screen.

[0120] In one 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 Figure 7 After step 204, the air purifier control method further includes step 702: controlling the cleaning device to start continuously when the humidity change index is the fourth index.

[0121] Specifically, the humidity change index can further include a fourth index, and the humidity change value of the fourth index is greater than the humidity change value of the third index, for example, the humidity change value corresponding to the fourth index is greater than 80%. When the humidity change index is the fourth index, it indicates that the humidity of the environment where the air purifier is located is too high, and in the environment with too high humidity, the growth rate of bacteria is at a high level, which is easy to breed a large amount of bacteria in a short time and affect the purification efficiency. In this case, the influence of the filter screen use time on the regeneration of the activated carbon of the filter screen does not need to be considered, and only the continuous sterilization of the filter screen and the activity of the activated carbon need to be ensured. Therefore, the controller can control the cleaning device to be continuously started, and the filter screen is continuously sterilized while ensuring the activity of the activated carbon of the filter screen.

[0122] Further, when the cleaning device is continuously started, it is not necessary to determine the starting time of the cleaning device of the air purifier, and it is not necessary to adjust according to the use time of the filter screen of the air purifier, and the cleaning device can be directly controlled to continuously operate.

[0123] In the embodiment, by setting different humidity change indexes, the conditions of the environment where the air purifier is located are fully considered, the filter screen is accurately sterilized, and the purification efficiency and the working reliability of the air purifier are ensured.

[0124] Based on the same technical concept, the 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 screen 106, a cleaning device 108, and a controller 110. The filter screen 106 is arranged in the purification body 104, the humidity detection device 102 and the cleaning device 108 are arranged in the filter screen 106, and the humidity detection device 102, the purification body 104 and the cleaning device 108 are connected to the controller 110.

[0125] The purification body 104 is a device capable of cooperating with the filter screen 106 to purify air, and the shape and material thereof are not limited. The purification body 104 can be provided with an air inlet and an air outlet on the surface, air can enter the purification body 104 from the air inlet, and purified air can be released through the air outlet. The filter screen 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 to remove dust, pollutants, bacteria and harmful gases such as formaldehyde. The filter screen 106 can be arranged on one side of the periphery of the purification body 104, or can be arranged on multiple sides of the periphery of the purification body 104, or can be arranged in the air flow cavity inside the purification body 104. Further, the filter screen 106 can be arranged not only at a position corresponding to the air inlet in the purification body 104, but also at a position corresponding to the air outlet in the purification body 104, to further filter the purified air and ensure the air purification effect.

[0126] The filter screen 106 can include a carbon cloth with activated carbon arranged therein, which can adsorb harmful components such as formaldehyde in the air and can be used to treat formaldehyde pollution. However, the carbon cloth is prone to bacterial growth in an environment with changing humidity, causing the filter screen 106 to produce an 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 increasing 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 arranged on the filter screen 106, it can detect the humidity data on the filter screen 106 and transmit the detected humidity data to the connected controller 110, so that the controller 110 monitors the humidity of the environment in which the air purifier is located, and controls the sterilization of the filter screen 106 by the cleaning device 108 according to the air purifier control method provided in the present application, to ensure the purification efficiency of the filter screen 106, and further ensure the purification efficiency of the air purifier.

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

[0129] The cleaning device 108 can also be other devices. In one exemplary embodiment, the cleaning device 108 is a microwave generating device. Since the adsorption effect of activated carbon on formaldehyde is limited, that is, there is a limit to the service life of activated carbon, as the use time accumulates, the adsorption effect of activated carbon on formaldehyde becomes worse and worse until it fails. The microwave generating device can generate microwaves, which can regenerate by microwave radiation, heat and dry the activated carbon, remove the adsorbate, and activate, with the advantages of reaction time, small loss of activated carbon, high regeneration efficiency, and developed micropores. Therefore, the controller 110 controls the microwave generating device to generate microwaves not only to sterilize the bacteria on the filter screen 106, but also to regenerate the activated carbon, prolong the service life of the activated carbon, and reduce the frequency of replacing the filter screen 106, thereby ensuring the purification efficiency of the air purifier.

[0130] In order to better understand the above scheme, the following will be explained in detail in conjunction with a specific embodiment.

[0131] In one embodiment, the air purifier comprises a humidity detection device, a purification body, a filter screen, a cleaning device and a controller, the filter screen is arranged in the purification body, the humidity detection device and the cleaning device are arranged in the filter screen, and the humidity detection device, the purification body and the cleaning device are connected to the controller. The filter screen comprises activated carbon, and the cleaning device is a microwave generating device, which can regenerate the activated carbon.

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

[0133] When the air humidity changes by less than or equal to 10% in one week, the microwave generating device is started once every 8 hours. When the remaining service life of the filter screen is less than 80%, the microwave generating device works for 0.5 hours each time. When the remaining service life of the filter screen is greater than or equal to 80%, the microwave generating device works for 0.2 hours each time. This logic is used to kill bacteria in the filter screen.

[0134] When the air humidity changes between 10% and 40% in one week, the ozone generating device is changed from being started once every 8 hours to being started once every 4 hours. When the remaining service life of the filter screen is less than 80%, the microwave generating device works for 1 hour each time. When the remaining service life of the filter screen is greater than or equal to 80%, the microwave generating device works for 0.5 hours each time. This logic is used to kill bacteria in the filter screen.

[0135] When the air humidity changes between 40% and 80% in one week, the ozone generating device is changed from being started once every 4 hours to being started once every 2 hours. When the remaining service life of the filter screen is less than 80%, the microwave generating device works for 1.5 hours each time. When the remaining service life of the filter screen is greater than or equal to 80%, the microwave generating device works for 1 hour each time. This logic is used to kill bacteria in the filter screen.

[0136] When the air humidity changes by more than 80% in one week, the ozone generating device is changed from being started once every 2 hours to being started once every 1 hour. At this time, the air humidity changes very much, and the bacteria will grow obviously. The microwave generating device works for 1 hour each time, and the continuous working time is 1 hour, that is, the microwave generating device runs continuously. This logic is used to kill bacteria in the filter screen.

[0137] In this embodiment, the influence of environmental humidity on the generation rate of bacteria in the filter screen is fully considered, and the purification efficiency of the filter screen is guaranteed in combination with the filter screen life. The humidity change index and the service life of the filter screen are used to control the working of the microwave generating device. The bacteria are accurately sterilized according to different working conditions of the filter screen, and the adsorption capacity of the activated carbon in the filter screen for formaldehyde is maintained. The sterilization effect can be effectively guaranteed, and the purification efficiency of the air purifier is guaranteed.
