[0030] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0031] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0032] Taking an air conditioner filter as an example, in the related art, the dust accumulation amount of the filter is usually calculated according to the particulate matter concentration of the current environment and the operating time of the air conditioner. However, such a calculation method has low accuracy, resulting in reminding the user to replace the filter when it is not necessary, thereby causing certain waste to the user; or, when the filter needs to be replaced, the user is not reminded to replace the filter, thereby affecting the user's physical health.

[0033] In view of the technical problems existing in the related art, the embodiments of the present application provide a method for monitoring the service life of a filter, which can accurately calculate the dust accumulation amount of the filter, and thus accurately estimate the remaining service life of the filter.

[0034] The following will, with reference to the accompanying drawings, describe in detail the method for monitoring the service life of a filter provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0035] As Figure 1 shown, a method for monitoring the service life of a filter provided by an embodiment of the present application may include the following steps 101 to 103:

[0036] Step 101: During the operation of the target device, determine the dust accumulation amount of the filter in each period of at least one period according to the operation parameters and environmental parameters of the target device.

[0037] Exemplarily, the above target device may be a device provided with a filter, such as an air conditioner or an air purifier, etc.

[0038] Exemplarily, the operating parameters of the above-mentioned target device may include: the operating time of the device, the wind force of the device fan, etc. The above environmental parameters are used to indicate the particulate matter concentration in the operating environment where the target device is located, and the environmental parameters may include: dust concentration, aerosol concentration, etc. The above fine particulate matter concentration can be determined by the following indicators: fine particulate matter (PM) PM2.5, PM10, etc.

[0039] Exemplarily, the dust accumulation amount of the filter screen in each period of the above at least one period is determined according to the operating parameters and environmental parameters corresponding to each period. The operating parameters and environmental parameters corresponding to different periods are not completely the same.

[0040] Specifically, the calculation steps for determining the dust accumulation amount of the filter screen in each period in step 101 above may include the following steps 101a:

[0041] Step 101a: Determine the dust accumulation amount of the filter screen in each period according to the dust concentration value collected by the dust sensor arranged at the air inlet of the target device, the filtration efficiency of the filter screen, the air output of the target device, and the operating time of the target device.

[0042] Exemplarily, in order to improve the calculation accuracy of the dust accumulation amount of the filter screen, each period can be divided more finely in time, and by calculating the dust accumulation amount of the filter screen per unit time, the dust accumulation amount of the filter screen in each period can be determined.

[0043] Further, the above step 101a may include the following steps 101a1 to 101a3:

[0044] Step 101a1: Collect the dust concentration value at the air inlet of the target device according to a preset period.

[0045] Step 101a2: Determine the dust accumulation amount of the filter screen per unit time according to the collected dust concentration value, the filtration efficiency of the filter screen, and the air output of the target device.

[0046] Step 101a3: Determine the dust accumulation amount of the filter screen in each period according to the operating time of the target device and the dust accumulation amount of the filter screen per unit time.

[0047] Exemplarily, the above unit time may correspond to the above preset period. For example, when the above unit time is one minute, the above preset period may also be one minute. That is, the target device collects the dust concentration value at the air inlet every minute, and calculates the dust accumulation amount of the filter screen in one minute according to the collected dust concentration value.

[0048] Exemplarily, the dust accumulation amount of the filter screen is positively correlated with the filtration efficiency of the filter screen and the air output. That is, under the same conditions, the higher the filtration efficiency of the filter screen, the greater the dust accumulation amount of the filter screen; the greater the air output of the target device, the greater the dust accumulation amount of the filter screen. Therefore, when calculating the dust accumulation amount of the filter screen, the filtration efficiency of the filter screen and the air output of the target device need to be considered.

[0049] For example, Figure 2 as shown, taking the above-mentioned target device as an air conditioner as an example, when the air conditioner is running, the dust concentration value (for example, the value of PM2.5 and / or PM10) at the air inlet can be collected once per minute. After that, according to the filtration efficiency of the filter screen, the air output at the air outlet of the air conditioner, and the running time of the air conditioner, the dust accumulation amount of the filter screen in each time period is calculated.

[0050] For example, taking the above-mentioned unit time as one minute and the above-mentioned one time period as one hour as an example, calculate the total dust amount of the filter screen of the target device in one hour: The target device collects the dust concentration value at the air inlet once per minute, and the obtained set of dust concentration values is [X1, X2, X3, X4…X60], with the unit being (grams per cubic meter g / m 3 ). Given that the filtration efficiency of the filter screen is Y%, and the air output of the target device is Z (unit: cubic meters per minute m 3 / min) during this one hour, then the total dust accumulation amount of the filter screen in this time period is: (X1 + X2 + X3 + X4…+ X60) × Y% × Z = K1.

[0051] Step 102: Calculate the current dust accumulation amount of the filter screen according to the dust accumulation amount of the filter screen in each time period and the weight corresponding to each time period.

[0052] Among them, the weight corresponding to the time period that is farther away from the current time in at least one time period is lower.

[0053] Exemplarily, after obtaining the dust accumulation amount of the filter screen in each time period, the current total dust accumulation amount of the filter screen can be calculated. Considering that the dust accumulated on the filter screen at an earlier time will be peeled off from the filter screen along with the vibration generated during the operation of the target device, the residual amount of the dust accumulated on the filter screen in an earlier time period is less. Based on this, when calculating the current total dust accumulation amount of the filter screen, weights need to be set for each time period, and the weight corresponding to the time period that is farther away from the current time is lower.

[0054] For example, according to the calculation method described in the example in the above step 101, after obtaining the dust accumulation amount of the filter screen in each time period [K1, K2, K3, K4…Kn], combined with the weight [P1, P2, P3, P4…Pn] corresponding to each time period, it is determined that the current dust accumulation amount of the filter screen is K1×P1 + K2×P2 + K3×P3 + K4×P4…+ Kn×Pn = K.

[0055] It should be noted that the vibration generated during the above-mentioned target operation process can be the vibration generated by the fan of the target device, or the vibration generated by a vibrator specifically provided on the target device for controlling the vibration of the filter screen.

[0056] In a possible implementation manner, a vibrator is further provided on the target device, and the vibrator is used to control the filter screen to vibrate so as to strip the dust on the filter screen.

[0057] Step 103: Determine the remaining service life of the filter screen according to the current dust accumulation amount of the filter screen.

[0058] Exemplarily, after obtaining the current dust accumulation amount of the filter screen, the remaining service life of the filter screen is determined according to the maximum load-bearing capacity of the filter screen.

[0059] For example, if the maximum dust accumulation amount that the filter screen can bear is 5 g and the calculated current dust accumulation amount of the filter screen is 3 g, then the remaining service life of the filter screen is 40%.

[0060] Optionally, in the embodiments of the present application, different prompting methods can be used to prompt the user according to the different remaining service lives of the filter screen.

[0061] Exemplarily, the above step 103 may include the following steps 103a1 and 103a2:

[0062] Step 103a1: When the current dust accumulation amount of the filter screen is less than a first preset threshold, determine that the remaining service life of the filter screen is a first service life.

[0063] Step 103a2: When the current dust accumulation amount of the filter screen is greater than or equal to the first preset threshold, determine that the remaining service life of the filter screen is a second service life.

[0064] Exemplarily, when the remaining service life of the filter screen is the first service life, it means that the dust accumulation amount on the filter screen is less and it can continue to be used; when the remaining service life of the filter screen is the second service life, it means that the dust accumulation amount on the filter screen is more and it needs to be replaced.

[0065] Furthermore, in the embodiments of the present application, for different remaining service lives of the filter screen, when the user replaces the filter screen, the target device can perform different operations.

[0066] Exemplarily, after the above step 103, the method for monitoring the service life of the filter screen provided by the embodiments of the present application may further include the following step 104 or step 105:

[0067] Step 104, when the remaining service life of the filter screen is the first service life, prompt the user to replace the filter screen, and when the user replaces the filter screen, control the fan of the target device to maintain the current operating state.

[0068] Step 105, when the remaining service life of the filter screen is the second service life, prompt the user to replace the filter screen, and when the user replaces the filter screen, turn off the fan of the target device.

[0069] It can be understood that when the dust accumulation amount on the filter screen is relatively large, if the user replaces the filter screen during operation, the dust accumulated on the filter screen may be blown away. At this time, it is necessary to turn off the fan of the target device; when the dust accumulation amount on the filter screen is relatively small, if the user replaces the filter screen during operation, the dust accumulated on the filter screen will hardly be blown away. At this time, there is no need to turn off the fan of the target device.

[0070] For example, as Figure 2 shown, if the current dust accumulation amount K of the filter screen > 5g (i.e., the above preset threshold), it is prompted that the dust accumulation amount of the current filter screen is relatively large and needs to be replaced, and when the user replaces the filter screen during the operation of the air conditioner (i.e., the above target device), the fan needs to be turned off; if the current dust accumulation amount K of the filter screen ≤ 5g, it is prompted that the dust accumulation amount of the current filter screen is relatively small and does not need to be replaced. If the user insists on replacing it, then when the user replaces the filter screen during the operation of the air conditioner (i.e., the above target device), the fan needs to be turned off to avoid the dust accumulated on the filter screen being blown away.

[0071] It should be noted that the monitoring method for the service life of the filter screen provided in the embodiments of the present application can be applied not only to the monitoring of the service life of the air conditioner filter screen, but also to the monitoring of the service life of the purifier filter screen.

[0072] In the monitoring method for the service life of the filter screen provided in the embodiments of the present application, during the operation of the target device, the dust accumulation amount of the filter screen in each period of at least one period is determined according to the operation parameters and environmental parameters of the target device. Then, according to the dust accumulation amount of the filter screen in each period and the weight corresponding to each period, the current dust accumulation amount of the filter screen is calculated. Finally, according to the current dust accumulation amount of the filter screen, the remaining service life of the filter screen is determined. This makes the calculation of the remaining service life of the filter screen of the target device more accurate, thereby reducing waste and the impact on the user's physical health.

[0073] It should be noted that for the monitoring method for the service life of the filter screen provided in the embodiments of the present application, the execution subject can be a monitoring device for the service life of the filter screen, or a control module in the monitoring device for the service life of the filter screen that executes the monitoring method for the service life of the filter screen. In the embodiments of the present application, the monitoring device for the service life of the filter screen executes the monitoring method for the service life of the filter screen as an example to illustrate the monitoring device for the service life of the filter screen provided in the embodiments of the present application.

[0074] It should be noted that in the embodiments of the present application, the monitoring methods of the service life of the filter screen shown in the above-mentioned various method drawings are all exemplified by taking one drawing in the embodiments of the present application as an example. In specific implementation, the monitoring methods of the service life of the filter screen shown in the above-mentioned various method drawings can also be implemented in combination with any other drawings that can be combined as shown in the above-mentioned embodiments, which will not be elaborated here.
