[0002] The existing humidifier based on ultrasonic principle can generate "white fog", i.e. small droplets, which can be mistaken by PM2.5 sensor as fine particulate matter or dust, resulting in changes of display values of PM2.5 sensor and formaldehyde sensor of the purifier, and causing inaccurate display values of air parameters of the purifier, which can cause users to lose confidence in the sensor / purifier. SUMMARY

[0003] The present application aims to at least solve one of the problems in the prior art or related art.

[0007] The fourth aspect of the present application provides a readable storage medium.

[0008] The fifth aspect of the present application provides an air treatment device.

[0009] Therefore, according to the first aspect of the present application, the present application provides a control method of an air treatment device, the air treatment device comprising a first sensor for detecting a first air parameter and a second sensor for detecting a second air parameter, the first air parameter being different in type from the second air parameter, the control method comprising: obtaining a plurality of first detection values detected by the first sensor in a first detection period; obtaining a plurality of second detection values detected by the second sensor in the first detection period; obtaining a plurality of third detection values detected by the first sensor in a second detection period; obtaining a plurality of fourth detection values detected by the second sensor in the second detection period; and displaying a first display value of the first air parameter and a first display value of the second air parameter according to a first average value of the plurality of first detection values, a second average value of the plurality of second detection values, a third average value of the plurality of third detection values, and a fourth average value of the plurality of fourth detection values.

[0010] The control method of the air treatment equipment provided by the application, the air treatment equipment comprises a first sensor and a second sensor, wherein the first sensor is used for detecting a first air parameter, and the second sensor is used for detecting a second air parameter, and it should be noted that the types of the first air parameter and the second air parameter are different.

[0011] Specifically, when the air treatment equipment is in an environment where an ultrasonic humidifier is used, the small droplets generated by the humidifier will affect the accuracy of the display values of the first sensor and the second sensor, causing the air treatment equipment to work abnormally and affecting the user experience. In order to solve the above problems, the control method provided by the application detects the first air parameter through the first sensor in the first detection period to obtain a first detection value, and detects the second air parameter through the second sensor to obtain a second detection value; in the second detection period, the first air parameter is detected through the first sensor to obtain a third detection value, and the second air parameter is detected through the second sensor to obtain a fourth detection value.

[0012] Further, the first average value of the plurality of first detection values, the second average value of the plurality of second detection values, the third average value of the plurality of third detection values, and the fourth average value of the plurality of fourth detection values are calculated, and according to the calculation result, the first display value of the first air parameter and the first display value of the second air parameter displayed by the air treatment equipment are accurately determined.

[0013] The control method of the air treatment equipment provided by the application, according to the change rule of the data detected by the first sensor and the second sensor when the ultrasonic humidifier is working, analyzes a plurality of groups of data detected by the first sensor and the second sensor, changes the control logic principle, effectively solves the problem that the data displayed by the first sensor and the second sensor is inaccurate when the humidifier is working, causes the air treatment equipment to work abnormally, improves the experience effect of the user using the air treatment equipment, and at the same time, without adding a humidity sensor on the air treatment equipment, reduces the manufacturing cost of the air treatment equipment.

[0014] In addition, the control method of the air treatment equipment provided by the above technical solution of the application also has the following additional technical features:

[0015] In the technical solution, the first display value of the first air parameter and the first display value of the second air parameter are displayed according to the first average value of the plurality of first detection values, the second average value of the plurality of second detection values, the third average value of the plurality of third detection values, and the fourth average value of the plurality of fourth detection values, and specifically, in a case where a difference between the third average value and the first average value is greater than a first value, the third average value is greater than a second value, and a difference between the second average value and the fourth average value is greater than a third value, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value.

[0016] In the technical solution, when the difference between the third average value and the first average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, it indicates that the changes in the data detected by the first sensor and the second sensor are both caused by the operation of the humidifier, and at this time, the first average value is taken as the first display value of the first air parameter, and the second average value is taken as the first display value of the second air parameter, thereby ensuring the accuracy of the display of the first air parameter and the second air parameter by the air treatment equipment and further ensuring that the air treatment equipment can be in a normal working state.

[0017] In the technical solution, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value, and specifically, a correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a preset time period is determined, and in a case where the correlation coefficient is less than or equal to a preset correlation coefficient, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value.

[0018] In the technical solution, before the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter, the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a preset time period is determined, and then compared with the preset correlation coefficient, and based on the determined correlation coefficient being less than or equal to the preset correlation coefficient, the first average value is taken as the first display value of the first air parameter, and the second average value is taken as the first display value of the second air parameter.

[0019] Specifically, the correlation coefficient is used to determine whether the changes of the third detection value and the fourth detection value (i.e. the changes of the data values detected by the first sensor and the second sensor) are affected by the same factor, and specifically, when the correlation coefficient is less than or equal to the preset correlation coefficient, it indicates that the changes of the data values detected by the first sensor and the second sensor are both affected by the same factor (the operation of the humidifier) and are correlated, and at this time, the first average value can be taken as the first display value of the first air parameter, and the second average value can be taken as the first display value of the second air parameter.

[0020] It should be noted that the preset time length is a period of time in the time length corresponding to the second detection period, or the entire time length corresponding to the second detection period can be taken as the preset time length to ensure the accuracy of the determined correlation coefficient. Further, the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a preset time length is calculated as follows:

[0021]

[0022] wherein Correl (X, Y) represents the required correlation coefficient, x represents the third detection value, represents the average value of the third detection value in the preset time length, y represents the fourth detection value, represents the average value of the fourth detection value in the preset time length.

[0023] In the above technical solution, the preset time length is less than or equal to the time length corresponding to the second detection period.

[0024] In this technical solution, the preset time length should be less than or equal to the time length corresponding to the second detection period, i.e. the preset time length should be within the time length corresponding to the second detection period, and less than or equal to the time length corresponding to the second detection period. It can be understood that the longer the preset time length, the higher the accuracy of the determined correlation coefficient of the third detection value and the fourth detection value. Generally, half of the time length corresponding to the second detection period is selected as the preset time length, and preferably the latter half of the time length corresponding to the second detection period is selected as the preset time length to improve the accuracy of the correlation coefficient.

[0025] In the above technical solution, the preset correlation coefficient is greater than -1 and less than or equal to -0.6.

[0026] In this technical solution, the preset correlation coefficient has a value range of less than or equal to -0.6 and greater than -1, which is preset, wherein the negative sign "-" is used to indicate that the changes of the third detection value and the fourth detection value are opposite, and specifically, when the correlation coefficient is equal to -1, it indicates that the third detection value and the fourth detection value are completely negatively correlated.

[0027] In the technical solution, the control method of the air treatment device further comprises: obtaining a plurality of fifth detection values detected by the first sensor in a third detection period; and in a case where a fifth average value of the plurality of fifth detection values is less than the first average value, canceling locking the first display value of the first air parameter as the first average value and canceling locking the first display value of the second air parameter as the second average value.

[0028] In the technical solution, in the third detection period, the first air parameter is detected by the first sensor to obtain a plurality of fifth detection values, and an average value of the plurality of fifth detection values is calculated, and when the average value is less than the first average value, it is indicated that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, and therefore, the second average value is no longer used as the second display value of the second air parameter, and the first detection value is directly used as the first display value of the first air parameter, and the second detection value is directly used as the second display value of the second air parameter.

[0029] In the technical solution, the first value is greater than or equal to 10; and / or the second value is greater than or equal to 35; and / or the third value is greater than or equal to 10.

[0030] In the technical solution, the first value is greater than or equal to 10, the second value is greater than or equal to 35, and the third value is greater than or equal to 10.

[0031] In the technical solution, before obtaining a plurality of third detection values detected by the first sensor in a second detection period, the control method further comprises: displaying the first detection value and the second detection value.

[0032] In the technical solution, before the third detection value is detected by the first sensor in the second detection period, it is unable to determine whether the humidity in the air has an impact on the display values of the first sensor and the second sensor, and therefore, before the third detection value is obtained, the detected first detection value is used as the first display value of the first air parameter, and the detected second detection value is used as the first display value of the second air parameter, so as to ensure that the display values of the air parameters are always provided as a reference for the user.

[0033] In the technical solution, the first sensor comprises one of a PM2.5 sensor and a VOC sensor, and the second sensor comprises a formaldehyde sensor.

[0034] In the technical solution, the first sensor is a PM2.5 sensor or a VOC sensor, and the second sensor is a formaldehyde sensor, which are arranged in the air treatment device to detect various air parameters in the environment where the air treatment device is located.

[0035] According to a second aspect of the present application, a control device of an air treatment device is provided, the air treatment device comprising a first sensor for detecting a first air parameter and a second sensor for detecting a second air parameter, the control device comprising: an acquisition unit configured to acquire a plurality of first detection values detected by the first sensor in a first detection period; acquire a plurality of second detection values detected by the second sensor in the first detection period; acquire a plurality of third detection values detected by the first sensor in a second detection period; acquire a plurality of fourth detection values detected by the second sensor in the second detection period; and a control unit configured to display a first display value of the first air parameter and a first display value of the second air parameter according to a first average value of the plurality of first detection values, a second average value of the plurality of second detection values, a third average value of the plurality of third detection values, and a fourth average value of the plurality of fourth detection values.

[0036] The control device of the air treatment device provided by the present application, the air treatment device comprises a first sensor and a second sensor, wherein the first sensor is configured to detect a first air parameter, and the second sensor is configured to detect a second air parameter, and it should be noted that the first air parameter and the second air parameter are of different types.

[0037] Specifically, when there is an ultrasonic humidifier in the environment where the air treatment device is located, the small droplets generated by the humidifier will affect the accuracy of the display values of the first sensor and the second sensor, causing the air treatment device to work abnormally and affecting the user experience. In order to solve the above problems, the control device of the air treatment device provided by the present application, in the first detection period, the acquisition unit detects the first air parameter through the first sensor to obtain the first detection value, and detects the second air parameter through the second sensor to obtain the second detection value; in the second detection period, the first air parameter is detected through the first sensor to obtain the third detection value, and the second air parameter is detected through the second sensor to obtain the fourth detection value.

[0038] Further, the control unit calculates a first average value of the plurality of first detection values, a second average value of the plurality of second detection values, a third average value of the plurality of third detection values, and a fourth average value of the plurality of fourth detection values, and accurately determines the first display value of the first air parameter and the first display value of the second air parameter displayed by the air treatment device according to the calculation result.

[0039] The control device of the air treatment equipment provided by the application effectively solves the problem of inaccurate display of the first sensor and the second sensor and abnormal operation of the air treatment equipment caused by the operation of the humidifier, improves the experience of the user using the air treatment equipment, and reduces the manufacturing cost of the air treatment equipment without adding a humidity sensor to the air treatment equipment.

[0040] In addition, the control device of the air treatment equipment provided by the above technical solution of the application has the following additional technical features.

[0041] In the above technical solution, the control unit displays the first display value of the first air parameter and the first display value of the second air parameter according to the first average value of the plurality of first detection values, the second average value of the plurality of second detection values, the third average value of the plurality of third detection values, and the fourth average value of the plurality of fourth detection values, and specifically includes: in the case where the difference between the third average value and the first average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value.

[0042] In the technical solution, when the control unit determines that the difference between the third average value and the first average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, it indicates that the changes of the data detected by the first sensor and the second sensor are both caused by the operation of the humidifier, and at this time, the first average value is taken as the first display value of the first air parameter, and the second average value is taken as the first display value of the second air parameter, thereby ensuring the accuracy of the display of the first air parameter and the second air parameter of the air treatment equipment and further ensuring that the air treatment equipment can be in a normal working state.

[0043] Specifically, the first value is greater than or equal to 10, the second value is greater than or equal to 35, and the third value is greater than or equal to 10.

[0044] In the above technical solution, the control unit is further configured to determine the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values within a preset time period; and in the case where the correlation coefficient is less than or equal to a preset correlation coefficient, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value.

[0045] In the technical solution, before the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter, the control unit needs to determine the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a preset time period, and then compare it with the preset correlation coefficient. Based on the determined correlation coefficient being less than or equal to the preset correlation coefficient, the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter.

[0046] Specifically, the preset time period should be less than or equal to the time period corresponding to the second detection period, and the preset time period should be ensured to be within the time period corresponding to the second detection period. It can be understood that the longer the preset time period is, the higher the accuracy of the determined correlation coefficient of the third detection value and the fourth detection value is. Generally, half of the time period corresponding to the second detection period is selected as the preset time period, and preferably the latter half of the time period corresponding to the second detection period, so as to improve the accuracy of the correlation coefficient.

[0047] Further, the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a preset time period is calculated as follows:

[0048]

[0049] wherein Correl(X, Y) represents the required correlation coefficient, x represents the third detection value, represents the average value of the third detection value in the preset time period, y represents the fourth detection value, represents the average value of the fourth detection value in the preset time period.

[0050] Further, the preset correlation coefficient has a value range of less than or equal to -0.6 and greater than -1, which is preset. The negative sign "-" is used to indicate that the changes of the third detection value and the fourth detection value are opposite. Specifically, when the correlation coefficient is equal to -1, it indicates that the third detection value and the fourth detection value are completely negatively correlated.

[0051] In the above technical solution, the acquisition unit is further configured to acquire a plurality of fifth detection values detected by the first sensor in a third detection period; and the control unit is further configured to calculate a fifth average value of the plurality of fifth detection values, and compare the fifth average value with the first average value of the first detection period. When the fifth average value is less than the first average value, the first display value of the first air parameter is unlocked as the first average value, and the first display value of the second air parameter is unlocked as the second average value.

[0052] In the technical solution, in the third detection period, the acquisition unit detects the first air parameter through the first sensor to obtain a plurality of fifth detection values, and the control unit calculates the average value of the plurality of fifth detection values, and when the average value is less than the first average value, it indicates that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, and thus, the second average value is not needed as the second display value of the second air parameter, and the first detection value is directly used as the first display value of the first air parameter, and the second detection value is used as the second display value of the second air parameter.

[0053] In the technical solution, before the acquisition unit acquires the plurality of third detection values detected by the first sensor in the second detection period, the control unit is further configured to control the air treatment device to display the first detection value and the second detection value.

[0054] In the technical solution, before the acquisition unit detects the third detection value through the first sensor in the second detection period, it is unable to determine whether the humidity in the air has an impact on the display values of the first sensor and the second sensor, and thus, before the acquisition unit acquires the third detection value, the control unit controls the air treatment device to display the first detection value as the first display value of the first air parameter and the second detection value as the first display value of the second air parameter, ensuring that the display value of the air parameter is always provided as a reference for the user.

[0055] According to a third aspect of the present application, a control device of an air treatment device is provided, comprising a memory and a processor, the memory stores a program, and the processor implements the steps of the control method of the air treatment device according to the first aspect when executing the program, thus having all the beneficial effects of the control method of the air treatment device, which will not be repeated here.

[0073] In order to enable a more complete understanding of the above-mentioned aspects, features and advantages of the present application, the present application will be further described below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0074] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0075] The following description will be made with reference to Figures 1 to 9 The air treatment device and the control method, device and readable storage medium thereof according to some embodiments of the present application are described clearly and completely.

[0076] Embodiment one

[0077] As Figure 1 shown, according to a first embodiment of the present application, a control method of an air treatment device is provided. The control method comprises:

[0078] Step S102: acquiring a plurality of first detection values detected by the first sensor in a first detection period;

[0079] Step S104: acquiring a plurality of second detection values detected by the second sensor in the first detection period;

[0080] Step S106: acquiring a plurality of third detection values detected by the first sensor in a second detection period;

[0081] Step S108: acquiring a plurality of fourth detection values detected by the second sensor in the second detection period;

[0082] Step S110: display the first display value of the first air parameter and the first display value of the second air parameter according to the first average value of the plurality of first detection values, the second average value of the plurality of second detection values, the third average value of the plurality of third detection values, and the fourth average value of the plurality of fourth detection values.

[0083] The control method of the air treatment equipment provided in the embodiment includes at least a first sensor and a second sensor, wherein the first sensor is configured to detect a first air parameter, and the second sensor is configured to detect a second air parameter. It should be noted that the first air parameter and the second air parameter are different in type. Specifically, the first air parameter is the concentration of PM2.5, and the second air parameter is the concentration of formaldehyde, but the present application is not limited thereto.

[0084] Specifically, when the air treatment equipment is used in an environment where an ultrasonic humidifier is used, the small droplets generated by the humidifier will affect the accuracy of the display values of the first sensor and the second sensor, causing the air treatment equipment to work abnormally and affecting the user experience. In order to solve the above problem, the first sensor is configured to detect the first air parameter to obtain a first detection value, and the second sensor is configured to detect the second air parameter to obtain a second detection value in a first detection period. The first sensor is configured to detect the first air parameter to obtain a third detection value, and the second sensor is configured to detect the second air parameter to obtain a fourth detection value in a second detection period.

[0085] It should be noted that the first detection period and the second detection period are in two different time stages. In general, the lengths of the first detection period and the second detection period are equal. The lengths of the first detection period and the second detection period can also be unequal, which is determined according to the actual application environment.

[0086] Further, the average values of the plurality of first detection values, the plurality of second detection values, the plurality of third detection values, and the plurality of fourth detection values are calculated as a first average value, a second average value, a third average value, and a fourth average value, respectively. The above plurality of average values are used to accurately determine the display values of the first air parameter and the second air parameter displayed by the air treatment equipment.

[0087] Specifically, in this embodiment, the first sensor is a PM2.5 sensor or a VOC sensor, and the second sensor is a formaldehyde sensor, but the present application is not limited thereto. Both are arranged in the air treatment equipment to detect various air parameters in the environment where the air treatment equipment is located.

[0088] It should be noted that the data values detected by the first sensor and the second sensor are both affected by the air humidity.

[0089] The control method of the air treatment equipment provided in the embodiment effectively solves the problem of inaccurate display data of the first sensor and the second sensor and abnormal operation of the air treatment equipment caused by the operation of the humidifier, improves the experience effect of the user using the air treatment equipment, and reduces the manufacturing cost of the air treatment equipment without adding a humidity sensor on the air treatment equipment.

[0090] Figure 2 The flowchart of the control method of the air treatment equipment provided in another embodiment of the application is shown, and the control method is combined with Figure 1 As shown in Figure 2 The step S110 specifically includes the following steps.

[0091] In the case that the difference between the third average value and the first average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, the first display value of the first air parameter is locked as the first average value, and the first display value of the second air parameter is locked as the second average value.

[0092] In the embodiment, in the case that the difference between the first average value and the third average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, it is indicated that the changes of the data detected by the first sensor and the second sensor are caused by the operation of the humidifier, and the first average value is used as the display value of the first air parameter, and the second average value is used as the display value of the second air parameter, so as to ensure the accuracy of the air treatment equipment in displaying the first air parameter and the second air parameter, and further ensure that the air treatment equipment can be in a normal working state.

[0093] Specifically, in the case that the difference between the first average value and the third average value is greater than the first value, and the third average value is greater than the second value, it is indicated that the data value detected by the first sensor is higher than that in the normal state, and it can be determined that the operation of the humidifier affects the data value detected by the first sensor, and the first average value is used as the display value of the first air parameter, so as to reduce the error of the data detected by the first sensor caused by the operation of the humidifier.

[0094] Further, when the difference between the second average value and the fourth average value is greater than the third numerical value, it indicates that the data value detected by the second sensor is lower than that in the normal state, at this time, it can be determined that the operation of the humidifier affects the data value detected by the second sensor, at this time, the second average value is taken as the display value of the second air parameter, so as to reduce the error of the data value detected by the second sensor caused by the operation of the humidifier. It should be noted that the first numerical value, the second numerical value and the third numerical value are obtained by pre-testing the first sensor and the second sensor in the normal working state, specifically, the first numerical value is greater than or equal to 10; the second numerical value is greater than or equal to 35; and the third numerical value is greater than or equal to 10.

[0095] The control method of the air treatment equipment provided in the embodiment compares the average values of the detection values of the first sensor and the second sensor in different detection periods with the standard numerical values obtained by pre-testing, judges whether the data values detected by the first sensor and the second sensor are affected by the operation of the humidifier, that is, whether they are affected by humidity, so that the application does not need to add a humidity sensor on the air treatment equipment, thereby saving the cost.

[0096] Figure 3 The flowchart of the control method of the air treatment equipment provided in another embodiment of the application is shown, and the control method is described in combination with Figure 2 As shown in Figure 3 The step S202 specifically includes the following steps.

[0097] Step S302: determining the correlation coefficient between the plurality of third detection values and the plurality of fourth detection values in a preset time period.

[0098] Step S304: in the case that the correlation coefficient is less than or equal to a preset correlation coefficient, locking the first display value of the first air parameter as the first average value and locking the first display value of the second air parameter as the second average value.

[0099] In this embodiment, before the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter, it is also necessary to determine the correlation coefficient between the plurality of third detection values and the plurality of fourth detection values in a preset time period, and then compare it with the preset correlation coefficient, and based on the determined correlation coefficient being less than or equal to the preset correlation coefficient, the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter.

[0100] Specifically, the correlation coefficient is used to determine whether the changes of the third detection value and the fourth detection value (i.e. the changes of the data values detected by the first sensor and the second sensor) are affected by the same factor, and specifically, when the correlation coefficient is less than or equal to the preset correlation coefficient, it indicates that the changes of the data values detected by the first sensor and the second sensor are both affected by the same factor (the operation of the humidifier) and have correlation, and at this time, the first average value can be taken as the first display value of the first air parameter, and the second average value can be taken as the first display value of the second air parameter.

[0101] It should be noted that in this embodiment, the preset correlation coefficient has a value range of less than or equal to -0.6 and greater than -1, which is preset, and the negative sign "-" is used to indicate that the changes of the third detection value and the fourth detection value are opposite, and specifically, when the correlation coefficient is equal to -1, it indicates that the third detection value and the fourth detection value are completely negatively correlated.

[0102] Further, the calculation formula of the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a period of time (i.e. in a preset time length) is as follows:

[0103]

[0104] Wherein, Correl (X, Y) represents the required correlation coefficient, x represents the third detection value, represents the average value of the third detection value in the preset time length, y represents the fourth detection value, represents the average value of the fourth detection value in the preset time length.

[0105] Specifically, the preset time length is a period of time in the time length of the second detection period, and the entire time length corresponding to the second detection period can be taken as the preset time length to ensure the accuracy of the determined correlation coefficient.

[0106] It should be noted that the preset time length should be less than or equal to the time length of the second detection period, i.e. the preset time length should be within the time length of the second detection period, and it can be understood that the longer the preset time length, the higher the accuracy of the determined correlation coefficient between the third detection value and the fourth detection value, and generally, half of the time length of the second detection period is selected as the preset time length, and preferably, the latter half of the time length of the second detection period is selected as the preset time length to improve the accuracy of the correlation coefficient.

[0107] Figure 4 The flowchart of the control method of the air treatment device according to another embodiment of the present application is shown, and the control method of the air treatment device further comprises:

[0108] Step S402: obtaining a plurality of fifth detection values detected by the first sensor in a third detection period;

[0109] Step S404: In the case that the fifth average value of the plurality of fifth detection values is less than the first average value, canceling the locking of the first display value of the first air parameter as the first average value, and canceling the locking of the first display value of the second air parameter as the second average value.

[0110] In this embodiment, in the third detection period, the first air parameter is detected by the first sensor to obtain a plurality of fifth detection values, and the average value of the plurality of fifth detection values is calculated and compared with the first average value, when it is less than the first average value, it indicates that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, so it is not necessary to take the second average value as the second display value of the second air parameter, and directly take the first detection value as the first display value of the first air parameter, and take the second detection value as the second display value of the second air parameter.

[0111] Specifically, the third detection period is the same as the first detection period and the second detection period, and is a different time period, and in general, the length of the third detection period is equal to that of the first detection period and the second detection period.

[0112] Further, the plurality of fifth detection values detected by the first sensor in the third detection period are used to determine that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, and when it is determined that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, the first detection value and the second detection value can be directly taken as the display value of the air parameter, which improves the accuracy of the determined first air parameter and the second air parameter display value.

[0113] Figure 5 The flowchart of the control method of the air treatment device according to another embodiment of the present application is shown, which is combined with Figure 1 As shown in Figure 5 Before the above step S106 is executed, the following step is further executed:

[0114] Step S502: Display the first detection value and the second detection value.

[0115] In this embodiment, before the third detection value is determined by the first sensor in the second detection period, it cannot be determined whether the humidity in the air has an influence on the display value of the first sensor and the second sensor, so before the above third detection value is obtained, the detected first detection value is taken as the display value of the first air parameter, and the detected second detection value is taken as the display value of the second air parameter, which ensures that there is always an air parameter display value to provide a reference for the user.

[0116] Embodiment two

[0117] As shown in Figure 6As shown, the second embodiment of the present application provides a control device 600 of an air treatment device, comprising: an acquisition unit 602, configured to acquire a plurality of first detection values detected by a first sensor in a first detection period; acquire a plurality of second detection values detected by a second sensor in the first detection period; acquire a plurality of third detection values detected by the first sensor in a second detection period; acquire a plurality of fourth detection values detected by the second sensor in the second detection period; and a control unit 604, configured to display a first display value of a first air parameter and a first display value of a second air parameter according to a first average value of the plurality of first detection values, a second average value of the plurality of second detection values, a third average value of the plurality of third detection values, and a fourth average value of the plurality of fourth detection values.

[0118] In the control device 600 of the air treatment device provided in the embodiment, the air treatment device comprises: a first sensor and a second sensor, wherein the first sensor is configured to detect a first air parameter, and the second sensor is configured to detect a second air parameter. It should be noted that the first air parameter and the second air parameter are of different types. Specifically, the first air parameter is the concentration of PM2.5, and the second air parameter is the concentration of formaldehyde, but is not limited thereto.

[0119] Specifically, when the air treatment device is in an environment where an ultrasonic humidifier is used, the small droplets generated by the humidifier will affect the accuracy of the display values of the first sensor and the second sensor, causing the air treatment device to work abnormally and affecting the user experience. In order to solve the above problem, the control device of the air treatment device provided in the embodiment acquires, by the acquisition unit 602, the first detection values by detecting the first air parameter by the first sensor and the second detection values by detecting the second air parameter by the second sensor in the first detection period; and acquires the third detection values by detecting the first air parameter by the first sensor and the fourth detection values by detecting the second air parameter by the second sensor in the second detection period.

[0120] It should be noted that the first detection period and the second detection period are in two different time stages. In general, the lengths of the first detection period and the second detection period are equal.

[0121] Further, the control unit 604 calculates the average values of the plurality of first detection values, the plurality of second detection values, the plurality of third detection values, and the plurality of fourth detection values, which are respectively the first average value, the second average value, the third average value, and the fourth average value. The above average values are used to accurately determine the display values of the first air parameter and the second air parameter displayed by the air treatment device.

[0122] Specifically, in this embodiment, the first sensor is a PM2.5 sensor or a VOC sensor, and the second sensor is a formaldehyde sensor, but is not limited thereto, and both are arranged in the air treatment device to detect various air parameters in the environment where the air treatment device is located.

[0123] It should be noted that the data values detected by the first sensor and the second sensor are both affected by air humidity.

[0124] The control device 600 of the air treatment device provided in this embodiment analyzes a plurality of groups of data detected by the first sensor and the second sensor according to the change rule of the data detected by the first sensor and the second sensor when the humidifier works based on the ultrasonic principle, changes the control logic principle, effectively solves the problem that the first sensor and the second sensor display inaccurate data when the humidifier works, causes the air treatment device to work abnormally, improves the experience effect of the user using the air treatment device, and at the same time, does not need to add a humidity sensor on the air treatment device, thereby reducing the manufacturing cost of the air treatment device.

[0125] In addition, the control device 600 of the air treatment device provided in the above technical solution of the present application also has the following additional technical features:

[0126] In the above embodiment, the control unit 604 is further configured to determine whether the difference between the first average value and the third average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, and if so, lock the first display value of the first air parameter as the first average value and lock the first display value of the second air parameter as the second average value.

[0127] In this embodiment, when the control unit 604 determines that the difference between the first average value and the third average value is greater than the first value, the third average value is greater than the second value, and the difference between the second average value and the fourth average value is greater than the third value, it indicates that the changes of the data detected by the first sensor and the second sensor are both caused by the working of the humidifier, and at this time, the first average value is taken as the first display value of the first air parameter, and the second average value is taken as the first display value of the second air parameter, thereby ensuring the accuracy of the air treatment device in displaying the first air parameter and the second air parameter, and further ensuring that the air treatment device can be in a normal working state.

[0128] Specifically, when the difference between the first average value and the third average value is greater than the first value, and the third average value is greater than the second value, it indicates that the data value detected by the first sensor is relatively high under the normal state, at this time, it can be determined that the working of the humidifier affects the data value detected by the first sensor, and at this time, the first average value is taken as the display value of the first air parameter, so as to reduce the error of the data detected by the first sensor caused by the working of the humidifier.

[0129] Further, when the difference between the second average value and the fourth average value is greater than the third numerical value, it indicates that the data value detected by the second sensor is lower than that in the normal state, at this time, it can be determined that the operation of the humidifier affects the data value detected by the second sensor, at this time, the second average value is taken as the display value of the second air parameter, so as to reduce the error of the data value detected by the second sensor caused by the operation of the humidifier. It should be noted that the first numerical value, the second numerical value and the third numerical value are obtained by pretesting the first sensor and the second sensor in the normal working state, specifically, the value range of the first numerical value is greater than or equal to 10; the value range of the second numerical value is greater than or equal to 35; and the value range of the third numerical value is greater than or equal to 10.

[0130] In the above embodiment, the control unit 604 is further configured to determine a correlation coefficient between the plurality of third detection values and the plurality of fourth detection values within the preset time period; and in a case where the correlation coefficient is less than or equal to a preset correlation coefficient, lock the first display value of the first air parameter as the first average value and lock the first display value of the second air parameter as the second average value.

[0131] In this embodiment, before the first average value is taken as the first display value of the first air parameter and the second average value is taken as the first display value of the second air parameter, the control unit 604 is further configured to determine a correlation coefficient between the plurality of third detection values and the plurality of fourth detection values within a time period, and then compare the correlation coefficient with a preset correlation coefficient, and determine to take the first average value as the first display value of the first air parameter and take the second average value as the first display value of the second air parameter based on the determined correlation coefficient being less than or equal to the preset correlation coefficient.

[0132] Specifically, the correlation coefficient is used to judge whether the changes of the third detection values and the fourth detection values (i.e. the changes of the data values detected by the first sensor and the second sensor) are affected by the same factor, specifically, when the correlation coefficient is less than or equal to the preset correlation coefficient, it indicates that the changes of the data values detected by the first sensor and the second sensor are both affected by the same factor (the operation of the humidifier), and have correlation, at this time, the first average value can be taken as the first display value of the first air parameter and the second average value can be taken as the first display value of the second air parameter.

[0133] It should be noted that in this embodiment, the value range of the preset correlation coefficient is less than or equal to -0.6 and greater than -1, which is pre-set, wherein the negative sign "-" is used to indicate that the changes of the third detection values and the fourth detection values are opposite, specifically, when the correlation coefficient is equal to -1, it indicates that the third detection values and the fourth detection values are completely negatively correlated.

[0134] Further, the calculation formula of the correlation coefficient of the plurality of third detection values and the plurality of fourth detection values in a period of time (i.e. in the preset time length) is as follows:

[0135]

[0136] wherein, Correl(X, Y) represents the required correlation coefficient, x represents the third detection value, represents the average value of the third detection value in the preset time length, and y represents the fourth detection value, represents the average value of the fourth detection value in the preset time length.

[0137] Specifically, the preset time length is a period of time in the time length of the second detection period, and the entire time length corresponding to the second detection period can be taken as the preset time length to ensure the accuracy of the determined correlation coefficient.

[0138] It should be noted that the preset time length should be less than or equal to the time length of the second detection period, i.e. the preset time length should be within the time length of the second detection period. It can be understood that the longer the preset time length is, the higher the accuracy of the determined correlation coefficient between the third detection value and the fourth detection value is. Generally, half of the time length of the second detection period is selected as the preset time length, and preferably the latter half of the time length of the second detection period is selected as the preset time length to improve the accuracy of the correlation coefficient.

[0139] In the above embodiment, the acquisition unit 602 is further configured to acquire a plurality of fifth detection values detected by the first sensor in a third detection period; and the control unit 604 is further configured to calculate a fifth average value of the plurality of fifth detection values, and compare the fifth average value with the first average value. When the fifth average value is less than the first average value, the first display value of the first air parameter is unlocked from the first average value, and the first display value of the second air parameter is unlocked from the second average value.

[0140] In this embodiment, in the third detection period, the acquisition unit 602 detects the first air parameter by the first sensor to acquire a plurality of fifth detection values, and the control unit 604 calculates the average value of the plurality of fifth detection values. When the average value is less than the first average value, it indicates that the data detected by the first sensor and the second sensor is no longer affected by the operation of the humidifier, and thus the second display value of the second air parameter is not required to be the second average value, and the first display value of the first air parameter is directly taken as the first detection value, and the second display value of the second air parameter is directly taken as the second detection value.

[0141] Specifically, the third detection period is the same as the first detection period and the second detection period, and is a different time phase. In general, the time length of the third detection period is equal to that of the first detection period and the second detection period.

[0142] Furthermore, the multiple fifth detection values ​​detected by the first sensor in the third detection cycle are used to determine whether the data values ​​detected by the first sensor and the second sensor are no longer affected by the operation of the humidifier. When it is determined that the data values ​​detected by the first sensor and the second sensor are no longer affected by the operation of the humidifier, the first detection value and the second detection value can be directly used as the display value of the air parameter, thereby improving the accuracy of the determined first air parameter and second air parameter display values.

[0143] In the above embodiment, before the acquisition unit 602 acquires the plurality of third detection values ​​detected by the first sensor in the second detection period, the control unit 604 is further configured to control the air handling device to display the first detection value and the second detection value.

[0144] In this embodiment, before the acquisition unit 602 determines the third detection value in the second detection cycle through the first sensor, it is impossible to determine whether the humidity in the air has an impact on the display values ​​of the first sensor and the second sensor. Therefore, before the acquisition unit 602 acquires the above-mentioned third detection value, the control unit 604 controls the air treatment equipment to detect the first detection value as the first display value of the first air parameter, and to detect the second detection value as the first display value of the second air parameter, ensuring that there is always a display value of the air parameter to provide a reference for the user.

[0147] The control device 600 of the air treatment equipment proposed in this embodiment analyzes multiple groups of data detected by the first sensor and the second sensor according to the change pattern of the data detected by the first sensor and the second sensor when the humidifier based on the ultrasonic principle is working, changes the control logic principle, and effectively solves the problem of inaccurate display data of the first sensor and the second sensor when the humidifier is working, which causes abnormal operation of the air treatment equipment. It improves the user experience of using the air treatment equipment. At the same time, there is no need to add a humidity sensor to the air treatment equipment, which reduces the production cost of the air treatment equipment.

[0152] The air treatment device 700 according to the present embodiment further comprises a purification assembly 704 for purifying air. Specifically, the control device 600 of the air treatment device controls the purification assembly 704 to operate according to the display values of the first sensor and the second sensor, so that the air parameters of the environment where the air treatment device 700 is located can meet the needs of the user.

[0154] The air treatment device according to the present embodiment can effectively solve the problem that the first sensor and the second sensor display inaccurate data when the humidifier is working, and the air treatment device works abnormally, without adding a humidity sensor to the air treatment device, improves the user experience of using the air treatment device, and reduces the manufacturing cost of the air treatment device.

[0155] Embodiment six

[0156] The sixth embodiment of the present application provides a specific application case of the control method of the air treatment device.

[0157] It should be noted that in this embodiment, the PM2.5 sensor of the purifier as the air treatment device is equivalent to the first sensor, and the formaldehyde sensor is equivalent to the second sensor. Specifically, when there is an ultrasonic humidifier in the environment where the purifier is located, the small droplets generated by the humidifier will affect the accuracy of the display values of the PM2.5 sensor and the formaldehyde sensor, causing the purifier to work abnormally and affecting the user's experience. In order to solve the above problems, the control method of the air treatment device proposed in this embodiment has the following specific steps:

[0158] First, after the purifier is started, record the readings x n0 and y n0 of the PM2.5 and formaldehyde sensors within 1 minute, and calculate the average values x0' and y0' of the sensor readings;

[0159] Second, record the readings x n1 and y n1 of the PM2.5 and formaldehyde sensors within 1 minute, and calculate the average values x1' and y1';

[0160] Third, if x1' - x0'> 10ug / m 3 and x1'> 35ug / m 3 are established (at this time, the PM2.5 sensor reading increases, and it may be caused by the operation of the humidifier); execute the fourth step; otherwise, execute the first step;

[0161] Fourth, if y1' - y0'< 10ug / m 3 , the formaldehyde sensor reading decreases, which may be caused by the effect of increased humidity caused by the operation of the humidifier; execute the fifth step, otherwise execute the first step;

[0162] Fifth, calculate the correlation coefficient of the PM2.5 sensor value x n1 and the formaldehyde sensor value y n1 within 30 seconds;

[0163] The calculation is performed by the following expression:

[0164]

[0165] Where Correl(X, Y) represents the correlation coefficient of the PM2.5 sensor value x n1 and the formaldehyde sensor value y n1 , x represents x n1 , represents the average value of x n1 within 30 seconds, y represents y n1 , represents yn1 the average value.

[0166] If the correlation coefficient Correl (xn1, yn1) <-0.6, it indicates that the changes of PM2.5 sensor value and formaldehyde sensor value are simultaneously affected by the same factor, and have correlation, wherein the negative sign "-" indicates that the changes of PM2.5 sensor value and formaldehyde sensor value are opposite, and Correl (xn1, yn1) =-1 indicates that the PM2.5 sensor value and the formaldehyde sensor value are completely negatively correlated.

[0167] If the correlation coefficient Correl (xn1, yn1) <-0.6, execute the sixth step, otherwise execute the first step;

[0168] The sixth step: the display values of the PM2.5 and formaldehyde sensors are locked as the initial average values x0' and y0';

[0169] The seventh step: record the PM2.5 readings x n2 in 1 minute, and calculate the average value x2';

[0170] The eighth step: if the PM2.5 sensor reading is less than the initial average value x0', that is, x2'-x0'<0, it indicates that the humidifier has no effect on the purifier, and x n0 and y n0 are taken as the display values of the PM2.5 and formaldehyde sensors, otherwise execute the seventh step.

[0171] In the embodiment, according to the fact that the humidifier working according to the ultrasonic principle causes the PM2.5 sensor value to rise and the formaldehyde sensor value to decrease, through sensor data analysis and control logic processing, the influence of the humidifier on the PM2.5 sensor and the formaldehyde sensor is reduced, the user experience of using the purifier is improved, and at the same time, the humidity sensor does not need to be installed in the purifier, and the cost is saved.
