Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The filter screen life monitoring method of the air purification equipment provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The air cleaning device 100 includes a controller 102, a first detecting device 106 installed at the air inlet 104, a second detecting device 110 installed at the air outlet 108, and a filter screen 112 installed between the air inlet 104 and the air outlet 108.
Specifically, the first detection device can obtain a first real-time PH value, the second detection device can obtain a second real-time PH value, and the controller can determine that the filter screen of the air purification device reaches the service life if the difference between the first real-time PH value and the second real-time PH value is smaller than a first preset value after obtaining the first real-time PH value from the first detection device and obtaining the second real-time PH value from the second detection device, and can remind a user to replace the filter screen of the air purification device by outputting prompt information when determining that the filter screen reaches the service life, so that the air purification quality of the air purification device is improved, and the health of the user when using the air purification device is ensured.
In one embodiment, the first detection device may include a first sensor and a first sprayer, the second detection device may include a second sensor and a second sprayer, and the first sensor may be a PH sensor. The first sensor can acquire a first real-time PH value after the gas entering from the air inlet and the liquid sprayed by the first sprayer act, and the second sensor can acquire a second real-time PH value after the gas purified by the filter screen and the liquid sprayed by the second sprayer act. The liquid sprayed by the first sprayer and the second sprayer may be purified water.
In one embodiment, as shown in fig. 2, a method for monitoring the life of a filter screen of an air cleaning apparatus is provided, and the method is applied to the controller 102 in fig. 1, and includes the following steps:
s202, acquiring a first real-time PH value detected by first detection equipment at the air inlet and a second real-time PH value detected by second detection equipment at the air outlet.
After the air inlet of the air purifying device absorbs the air from the environment, the filter screen in the air purifying device purifies the air, so that the purified air can be returned to the environment through the air outlet, and the effect of purifying the air in the environment is achieved. It will be appreciated that the gas in the environment is typically an acid gas or an alkaline gas, and that after the screen cleans the acid gas or alkaline gas, the PH of the gas before and after cleaning is different from the PH of the liquid after the gas and liquid are reacted. Therefore, the service life of the filter screen can be monitored through the PH value change of the filter screen at the gold air inlet and the gold air outlet before and after the filter screen absorbs acid gas or alkaline gas.
Specifically, a first real-time PH value after the gas entering from the air inlet reacts with the liquid sprayed by the first sprayer can be obtained through the first sensor, and a second real-time PH value after the gas purified by the filter screen reacts with the liquid sprayed by the second sprayer can be obtained through the second sensor, so that the service life of the filter screen can be monitored.
S206, when the difference value between the first real-time PH value and the second real-time PH value is smaller than a first preset value, determining that the filter screen of the air purifying device reaches the service life.
In this embodiment, referring to fig. 1, the first real-time PH is the real-time PH detected by the first detecting device at the air inlet, and the second real-time PH is the real-time PH detected by the second detecting device at the air outlet. Specifically, if the difference between the first real-time PH value and the second real-time PH value is smaller than the first preset value, it is indicated that the adsorption capacity of the filter screen to the gas is weak, and therefore it can be determined that the filter screen has reached the service life. The first preset value may be 0.5 or other values, and may specifically be set according to an actual application scenario, which is not limited in this embodiment.
S208, outputting prompt information when the filter screen is determined to reach the service life; wherein, the prompt message is used for reminding the user to replace the filter screen of the air purifying device.
In this embodiment, the controller may alert the user to change the filter screen in three ways. The first way is: the reminding information is output through the display screen of the air purifying device so as to prompt a user to replace the filter screen. The second mode is as follows: the air purification device can be reminded by a reminding lamp, for example, the reminding lamp can be always on or flash on. The third way may be: the controller can transmit the prompt information to the application corresponding to the air purifying device, so that a user can see the prompt information for replacing the filter screen when opening the application. It can be understood that the intelligent control of the air purifying device by the user can be realized on the application corresponding to the air purifying device.
In summary, in the embodiment shown in fig. 2, by acquiring the first real-time PH value detected by the first detecting device at the air inlet and the second real-time PH value detected by the second detecting device at the air outlet, when the difference between the first real-time PH value and the second real-time PH value is smaller than the first preset value, it is determined that the filter screen of the air purifying device reaches the service life, and then when it is determined that the filter screen reaches the service life, the user is reminded to replace the filter screen of the air purifying device by outputting prompt information, so as to improve the air purifying quality of the air purifying device, and thereby ensure the health of the user when using the air purifying device.
Based on the embodiment shown in fig. 2, in one embodiment, as shown in fig. 3, a flow chart for acquiring a first real-time PH value detected by a first detecting device at an air inlet and a second real-time PH value detected by a second detecting device at an air outlet is provided, which includes the following steps:
S302, a plurality of groups of first target PH values detected by first detection equipment at the air inlet in a target detection time period according to a first detection period and a plurality of groups of second target PH values detected by second detection equipment at the air outlet in the target detection time period according to the first detection period are obtained.
In this embodiment, the target detection duration is a detection duration set for detecting a lifetime of a filter screen of the air cleaning apparatus, and the target detection duration may be one week, 48 hours, or one day, or the like. The first detection period is a detection interval in the target detection period, and the first detection period may be 2 hours, 3 hours, 4 hours, or the like. Specifically, in the target detection duration, multiple groups of first target PH values detected by the first detection device at the air inlet may be obtained according to every first detection period, and in the target detection duration, multiple groups of second target PH values detected by the second detection device at the air outlet may be obtained according to every first detection period.
S304, a plurality of groups of PH value differences are obtained according to a plurality of groups of first target PH values and a plurality of groups of second target PH values.
In this embodiment, after multiple groups of first target PH values detected by the first detecting device at the air inlet and multiple groups of second target PH values detected by the second detecting device at the air outlet are obtained at intervals of a first detecting period within a target detecting period, multiple groups of PH value differences may be obtained by subtracting the corresponding multiple groups of first target PH values and multiple groups of second target PH values.
S306, adjusting the first detection period to a second detection period according to the difference value between the maximum value and the minimum value in the plurality of groups of PH value difference values.
In this embodiment, after the corresponding multiple sets of first target PH values and multiple sets of second target PH values are subtracted to obtain multiple sets of PH value differences, a maximum value and a minimum value may be determined from the multiple sets of PH value differences, so as to update the first detection period according to the difference between the maximum value and the minimum value in the multiple sets of PH value differences, and update the first detection period to the second detection period. Wherein, the larger the difference between the maximum value and the minimum value in the plurality of groups of PH value differences is, the larger the second detection period is.
S308, the first real-time PH value and the second real-time PH value are obtained according to the second detection period.
In summary, in the embodiment shown in fig. 3, by obtaining multiple groups of first target PH values detected by the first detecting device at the air inlet according to the first detecting period in the target detecting period and multiple groups of second target PH values detected by the second detecting device at the air outlet according to the first detecting period in the target detecting period, multiple groups of PH value differences are obtained according to the multiple groups of first target PH values and the multiple groups of second target PH values, and the first detecting period is adjusted to the second detecting period according to the difference between the maximum value and the minimum value in the multiple groups of PH value differences, so that the first real-time PH value and the second real-time PH value can be obtained according to the second detecting period. The larger the difference value between the maximum value and the minimum value in the PH value difference values is, the larger the second detection period is, so that the detection period of the service life of the filter screen is adjusted in real time according to the difference value between the maximum value and the minimum value in the PH value difference values, and the filter screen can be timely monitored to judge whether the service life of the filter screen is reached or not when air is purified, so that a user can be timely reminded of replacing the filter screen when the service life of the filter screen is confirmed, the resource waste caused by too early replacement of the filter screen is avoided, and certain harm to the health of the user caused by too late replacement of the filter screen is avoided.
In the embodiment shown in fig. 3, the adjusting the first detection period to the second detection period according to the difference between the maximum value and the minimum value of the multiple sets of PH value differences includes: if the difference value between the maximum value and the minimum value in the plurality of groups of PH value difference values is larger than a second preset value, determining a second detection period according to the first detection period and the first value; wherein the second detection period is greater than the first detection period. For example, the second preset value may be 2, the first value may be 2 hours, the first detection period may be 2 hours, and the second detection period may be 4 hours.
It can be understood that when the difference between the maximum value and the minimum value in the plurality of groups of PH value differences is greater than the second preset value, the service life of the filter screen is longer or the air quality is worse, and by increasing the detection period, the service life of the filter screen can be monitored, and meanwhile, the service lives of the first detection device and the second detection device can be prolonged while the service life of the filter screen is monitored too much.
In one embodiment, if the difference between the maximum value and the minimum value in the plurality of sets of PH values is less than or equal to a second preset value, and the difference between the maximum value and the minimum value in the plurality of sets of PH values is greater than a third preset value, determining a second detection period according to the first detection period and the second value; wherein the second detection period is smaller than the first detection period. For example, the second preset value may be 2, the third preset value may be 1, the first detection period may be 2 hours, the second value may be-1, and the second detection period may be 1 hour.
It can be understood that when the difference between the maximum value and the minimum value in the plurality of groups of PH values is smaller than or equal to the second preset value, and the difference between the maximum value and the minimum value in the plurality of groups of PH values is larger than the third preset value, the service life of the filter screen is smaller or the air quality is better, by reducing the detection period, the service life of the filter screen can be monitored in time through frequent monitoring, so that the user can be reminded of replacing the filter screen in time.
In one embodiment, if the difference between the maximum value and the minimum value in the plurality of sets of PH difference values is less than or equal to a third preset value, and the difference between the maximum value and the minimum value in the plurality of sets of PH difference values is greater than a first preset value, determining a second detection period according to the first detection period and the third value; wherein the second detection period is smaller than the first detection period, and the third value is smaller than the second value. For example, the third preset value may be 1, the first preset value may be 0.5, the first detection period may be 2 hours, the third value may be-1.5, and the second detection period may be 0.5 hours.
It can be understood that when the difference between the maximum value and the minimum value in the plurality of groups of PH values is smaller than or equal to the third preset value, and the difference between the maximum value and the minimum value in the plurality of groups of PH values is larger than the first preset value, the service life of the filter screen is less, and the service life of the filter screen is frequently monitored by reducing the detection period, so that the service life of the filter screen can be timely monitored, and a user can be timely reminded of replacing the filter screen.
In one embodiment, after updating the first detection period to the second detection period, the controller may further control the air purifying device to operate according to the air intake corresponding to the second detection period. The larger the second detection period is, the larger the air inlet corresponding to the second detection period is. For example, the first detection period is 2 hours, and the second detection period is 4 hours, and then the controller controls the air purifying device to increase the air inlet amount by two times to purify the air. The first detection period is 2 hours, and the second detection period is 1 hour, and then the controller controls the air purifying equipment to increase the air inlet quantity by one time to purify the air. The first detection period is 2 hours, and the second detection period is 0.5 hour, and then the controller controls the air purifying device to purify air according to the current air inlet quantity.
In one embodiment, when the controller determines that the filter screen has reached the service life and outputs the prompt message, the controller may control the air purifying device to stop working until the user changes the filter screen in order to avoid the risk to the health of the user caused by continuously using the air purifying device.
In combination with the foregoing, in one embodiment, as shown in fig. 4, there is provided a screen life monitoring method of an air cleaning apparatus, comprising the steps of:
S402, multiple groups of first target PH values detected by first detection equipment at the air inlet in a target detection time period according to a first detection period and multiple groups of second target PH values detected by second detection equipment at the air outlet in the target detection time period according to the first detection period are obtained.
S404, a plurality of groups of PH value differences are obtained according to a plurality of groups of first target PH values and a plurality of groups of second target PH values.
When the first detection period is updated according to the difference value between the maximum value and the minimum value in the plurality of groups of PH value difference values, and the magnitude relation between the difference value between the maximum value and the minimum value in the plurality of groups of PH value difference values and the preset value is different, the updated second detection period is also different, specifically:
S4061, if the difference between the maximum value and the minimum value in the plurality of groups of PH value differences is larger than a second preset value, determining a second detection period according to the first detection period and the first value; wherein the second detection period is greater than the first detection period.
