首先，本领域技术人员应当理解的是，这些实施方式仅仅用于解释本申请的技术原理，并非旨在限制本申请的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，虽然本申请的滤网可用时长确定方法是结合智能空调来描述的，但是这并不是限定的，其他具有确定滤网可用时长需求的设备均可配置本申请的滤网可用时长确定，如空气净化器设备。

下面对本申请实施例的应用场景进行解释：
图1为本申请实施例提供的滤网可用时长确定方法的一种应用场景图，本实施例提供的方法可以应用在智能家居的应用场景下，具体地，本方法的执行主体可以为智能空调，如图1所示，智能空调接收来自终端设备或者云服务器的运行指令后，按照运行指令启动运行，其中，运行指令中包括温度参数和风量参数，分别用于控制智能空调的制冷/制热温度和出风量，其中，智能空调包括多个出风单元，各出风单元能够以不同的风量参数出风。示例性地，各出风单元内对应设置有用于过滤空气的空调滤网，智能空调对各出风单元的空滤滤网进行监测，根据监测结果，确定并输出一个对智能空调的空气滤网进行整体更换的剩余时长。
更具体地，该智能空调可以为中央智能空调、商用智能空调等，此类智能空调由于需要专业的维护人员对其进行清理和空调滤网更换等维护工作，因此，用户可以根据本申请实施例提供的滤网可用时长确定方法所输出的剩余时长，进行智能空调整体滤网更换的保修，或者，智能空调通过将根据本申请实施例提供的滤网可用时长确定方法所输出的剩余时长发送至售后维护方的服务器，实现智能空调的智能售后维护。
现有技术中，为了保证空调的换热效果和空气过滤效果，空调滤网在每过一段时间后，需要进行更换或清洗，智能空调通常是检测到其中一个出风单元的空气滤网达到堵塞阈值后，就会向用户发出提示信息。然而，在实际使用过程中，对于多出风单元的空调设备，由于多出风单元内的空气滤网的灰尘积累速度不同，基于其中一个或几个滤网的堵塞程度发出滤网更换提示，会导致部分滤网的提前更换，浪费滤网使用寿命。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图2为本申请一个实施例提供的滤网可用时长确定方法的流程图，应用于电子设备，电子设备包括多个出风单元，每一出风单元对应一个空气滤网，具体地，电子设备例如为智能空调，本实施例以智能空调为例对本实施例提供的滤网可用时长确定方法进行说明，其中，本实施例提供的滤网可用时长确定方法的执行主体可以为智能空调或者智能空调的控制器，空气滤网在本实施例中为空调滤网，更具体地，空调滤网可以包括滤尘网，和/或，用于过滤PM2.5颗粒、PM10颗粒的空气颗粒物过滤网等。出风单元包括风机、对应出风通道和出风口，空调滤网设置在出风口位置或者出风通道内，空调滤网的设置遵循本领域常规的空调滤网的设置方式的，此处不做特别限定。如图2所示，本实施例提供的滤网可用时长确定方法包括以下几个步骤：
步骤S101，获取每一空调滤网的堵塞信息，堵塞信息用于表征空调滤网的堵塞程度。
示例性地，堵塞信息可以是通过传感器对空调滤网进行检测后，获得的表征空调滤网堵塞程度的信息。更具体地，空调滤网的堵塞程度，是指其阻碍空气穿过、降低空气穿过量的数值。其中，通过传感器对空调滤网进行检测的方式有多种，例如，智能空调内设置有用于发射光信号的光发射单元，以及用于接收光信号的光接收单元，光发射单元和光接收单元相对设置于空调滤网两侧，获取堵塞信息的过程包括：控制光发射单元向光接收单元发送光线；根据光接收单元接收到的光量，确定堵塞信息。其中，具体地，光发射单元可以包括红外线发射器、激光发射器等，通过光发射单元作为光源向空调滤网发射光线，在空调滤网的另一侧设置光接收单元，接收穿过滤网的光线。当空调滤网被堵塞后，会影响空调滤网的透光率，进而使光接收单元接收到的光量发生变化，从而确定空调滤网的堵塞程度。其中，光接收单元接收到的光量与空调滤网的堵塞程度直接，具有固定的映射关系，该具体的映射关系可以通过测试和实验获得，此处不进行赘述。
在另一种可能的实现方式中，每一空调滤网的堵塞信息，可以通过响应用户输入的检测指令，进入测试状态，并在测试状态下进行空调滤网堵塞测试而获得，其中，示例性地，通过在测试状态下进行空调滤网堵塞测试，而获取每一空调滤网的堵塞信息的步骤，如图3所示，包括：
步骤S1011，获取预设的阶梯风量序列，阶梯风量序列中包括至少两个不同的风量值。
步骤S1012，根据阶梯风量序列，以不同的风量值控制每一出风单元出风，并通过设置在出风口的风量检测单元检测每一出风单元的出风量。
步骤S1013，基于每一出风单元以不同的风量值出风时检测到的出风量，确定每一空调滤网的堵塞信息。
示例性地，阶梯风量序列是由至少两个风量值组成的序列，其中，风量值可以是具体的表征风量大小的数值，例如300立方米/小时；也可以是基于最大风量的百分比值，例如90％、50％。进一步地，由于智能空调内设置的空调滤网对实际出风量的衰减，受多个因素的影响，例如空调滤网的结构、尺寸等，其对出风单元出风的阻挡能力，并不是线性的，在出风单元的风量值不同时，其对应的出风量衰减率也是不同的，例如，在风量值为10时，由于风速大，对于某些滤网材料的空调滤网，可以增加空气的穿透性，使出风量的衰减较小，例如出风量衰减率为10％，此时，相当于空调滤网的堵塞程度较小；而在出风量参数对应的出风档位为“低风量”时，由于风速小，会降低空气在该种滤网材料中的穿透性，使出风量的衰减较大，例如出风量衰减率为30％。此时，相当于空调滤网的堵塞程度较大。因此，出风单元以不同的风量值出风时，根据风量检测单元检测到的实际出风量，所评估出来的空调滤网的堵塞信息也不同。示例性，图4为本申请实施例提供的一种空调滤网的堵塞信息的示意图，如图4所示，空调滤网的堵塞信息可以表征为一组二维序列，不同风量值，对应一个堵塞程度值，具体地，例如图4中所示，当风量值为1时，对应堵塞程度值为50；当风量值为2时，对应堵塞程度值为30；当风量值为3时，对应堵塞程度值为20，其中，风量值和堵塞程度值的单位，可以根据具体算法确定，例如，风量值1为出风单元的1档风速；堵塞程度值50表征滤网对穿过其的空气阻挡50％。其中，该空调滤网的堵塞信息，可以通过阶梯风量序列中的风量值，依次进行测试而确定。
其中，进一步地，阶梯风量序列中的各出风量，是根据智能空调的具体出风档位所对应的出风量所确定的，对于不同型号、参数的智能空调，阶梯风量序列可以不同，该阶梯风量序列可以是在智能空调出厂时预设在智能空调内部的数据。
本实施例中，通过根据阶梯风量序列中的各出风量，确定能够表征在不同风量值时空调滤网的堵塞程度的堵塞信息，从而使堵塞信息与出风量相匹配，提高堵塞信息的精确度，进而提高后续出风总量的预测精度以及可用时长的预测精度。
步骤S102，根据各空调滤网的堵塞信息，确定当前出风总量，其中，当前出风总量用于表征各出风单元当前的实际出风量之和，当前出风总量随着空调滤网的堵塞程度增加而降低。
示例性地，当堵塞信息不相同时，空调滤网对应的对出风量的阻挡能力也不同，即，出风单元由于各自的空滤滤网的堵塞，出风量不相同。在确定各出风单元的空调滤网的堵塞信息后，根据堵塞信息所表征的空调滤网的堵塞程度，进而确定各出风单元的出风量。示例性地，各出风单元的出风量，可以是指各出风单元以最大风量值出风时的出风量。当各出风单元的空调滤网中的部分空调滤网发生堵塞后，通过适应性的调节未发生堵塞，或者堵塞程度较小的空调滤网对应的出风单元的风量值，实现对由于滤网堵塞造成的出风量的补偿。例如，空调滤网A和空调滤网B发生堵塞，使出风单元A和出风单元B的实际出风量降低，此时，通过提高出风单元C的风量值，使出风单元C的实际出风量提高，补偿由于空调滤网A和空调滤网B发生堵塞而造成的风量降低，从而使各出风单元的总的实 际出风量不变。
进一步地，将根据堵塞信息预设的各出风单元的最大出风量之和，确定为当前出风总量。其中，当前出风总量相当于是基于当前各空调滤网的堵塞程度，各出风单元所能达到的最大出风量之和。该当前出风总量，也表征智能空调当前所能提供的最大空气交换能力。
步骤S103，根据当前出风总量，确定可用时长，其中，可用时长表征当前出风总量由于空调滤网的堵塞程度增加而降低至预设的第一出风阈值所需的时长。
具体地，随着空调滤网堵塞程度的增加，该当前出风总量会逐渐降低，当该当前出风总量降低至一定水平后，会使智能空调的出风量难以达到用户设置的出风要求，进而使智能空调的制冷/制热效果，或者空气过滤效果受到影响，无法达到智能空调的正常功效。而由当前出风总量降低至该智能空调的出风量恰达到用户设置的出风要求的临界出风量，即为第一出风阈值。示例性地，该第一出风阈值为预设的能够保证空调正常功效的最低出风量，例如，正常工作的智能空调的最小风量值对应的出风量。也即，当智能空调将所有出风单元调节至最大风量值时，其出风总量仍无法达到未发生滤网堵塞的智能空调的最小风量值对应的出风总量，则认为智能空调无法达到正常功效，应进行空调滤网的整体更换。而由当前出风总量降低至第一出风阈值所需的时长，即为可用时长。
进一步地，确定可用时长的方法，例如为，根据预设的灰尘积累系数，确定空调滤网由于灰尘积累，各出风单元的出风总量由当前出风总量降低至第一出风阈值所需的时长。其中，灰尘积累系数是表征单位时间内由于灰尘积累造成出风量的降低量的数值。该灰尘积累系数可以通过测试或模拟的方式确定并预存在智能空调内，此处不再赘述。
本实施例中，通过获取每一空调滤网的堵塞信息，堵塞信息用于表征空调滤网的堵塞程度；根据各空调滤网的堵塞信息，确定当前出风总量，其中，当前出风总量用于表征各出风单元当前的实际出风量之和，当前出风总量随着空调滤网的堵塞程度增加而降低；根据当前出风总量，确定可用时长，其中，可用时长表征当前出风总量由于空调滤网的堵塞程度增加而降低至预设的第一出风阈值所需的时长。由于多出风单元的设备，当出现个别出风单元的空调滤网堵塞后，其所导致的出风量衰减可以由其他出风单元通过增大出风量而补充，从而使总的出风量不变，因此根据每一空调滤网的堵塞信息确定当前出风总量，进而根据当前出风总量确定可用时长，可以更准确的判断电子设备中空调滤网的真实可用时长，从而提高空调滤网的更换周期，避免空调滤网的过早更换，降低用户的使用成本。
图5为本申请另一个实施例提供的滤网可用时长确定方法的流程图，如图5所示，本实施例提供的滤网可用时长确定方法在图2所示实施例提供的滤网可用时长确定方法的基础上，对步骤S102-S103进一步细化，并增加了输出可用时长的步骤，则本实施例提供的滤网可用时长确定方法包括以下几个步骤：
步骤S201，获取每一空调滤网的堵塞信息，堵塞信息用于表征空调滤网的堵塞程度。
步骤S202，根据每一空调滤网的堵塞信息，确定每一对应的出风单元的最大出风量。
步骤S203，根据各出风单元的最大出风量之和，确定当前出风总量。
具体地，在一种可能的实现方式中，堵塞信息能够表征在不同风量值时空调滤网的堵塞程度。例如，出风单元在以第一档风量值出风时，空调滤网由于堵塞阻挡30％的风量，空调滤网处于第一堵塞程度；出风单元在以第二档风量值出风时，空调滤网由于堵塞阻挡50％的风量，空调滤网处于第二堵塞程度。因此，根据每一空调滤网的堵塞信息，可以确 定出风单元在以最大风量值出风时，其实际从出风口输出的最大出风量。进而，根据各出风单元最大出风量之和，确定各出风单元当前能够达到的最大出风总量，即当前出风总量。
本实施例中，通过每一空调滤网的堵塞信息，确定出每一对应的出风单元的最大出风量，由于考虑了不同的风量值对空调滤网的堵塞程度(即空调滤网的透风能力)的影响，因此，能够快速、准确的判断出智能空调当前的最大出风能力(即当前出风总量)，提高后续确定可用时长的精确性，避免空调滤网可用时长的浪费，或者影响智能空调作业功效的问题。
步骤S204，根据当前出风总量与预设的第一出风阈值的差值，确定出风冗余量。
步骤S205，获取灰尘积累系数，并根据灰尘积累系数，确定出风冗余量对应的可用时长。
其中，灰尘积累系数用于表征单位时间内出风冗余量的减少量，灰尘积累系数是通过滤网信息确定的，滤网信息用于表征空调滤网的孔径尺寸。示例性地，灰尘积累系数是表征出风冗余量减少速度的信息，例如，灰尘积累系数越大，则出风冗余量减少速度越快。更具体地，例如，灰尘积累系数为2立方米/日，即出风冗余量每天减少2立方米，当出风冗余量为0时，当前出风总量到达智能空调能够正常工作的临界点。之后，智能空调由于出风量必然小于第一出风阈值，则智能空调的作业功效无法达到正常水平，需要进行空调滤网更换。
可选地，如图6所示，步骤S205中获取灰尘积累系数的实现方法包括S2051和S2052两个步骤：
步骤S2051，获取滤网更换历史数据，滤网更换历史数据表征各空调滤网的历史更换周期。
步骤S2052，根据预设第二出风阈值与预设第一出风阈值的差值，以及滤网更换历史数据，确定灰尘积累系数，其中，预设第二出风阈值为智能空调的各空调滤网不堵塞时，各出风单元的出风量之和。
具体地，滤网更换历史数据是指对空调中的全部滤网进行整体更换的历史记录数据，根据滤网更换历史记录，可以确定滤网整体更换的周期，例如100天。该周期可以是通过多个滤网整体更换周期的平均值确定的，也可以是根据最近的一个滤网整体更换周期确定的，此处不进行具体限定。进一步地，在确定滤网更换历史数据后，根据第二出风阈值与预设第一出风阈值的差值，确定出风量变化范围，其中，第一出风阈值是智能空调能够保证正常工作的最小出风量；第二出风阈值是智能空调的各空调滤网均不堵塞时，智能空调能达到的最大出风量；其中，示例性地，第一出风阈值和第二出风阈值是指在相同风量值下的最小出风量和最大出风量，根据第一出风阈值和第二出风阈值，以及滤网更换历史数据所表征的各空调滤网的历史更换周期，确定在不风量值下的灰尘积累系数。例如，在第一档风量值下，灰尘积累系数为a；在第二档风量值下，灰尘积累系数为b。进而，在后续的处理步骤中，根据灰尘积累系数，确定出风冗余量对应的可用时长。
步骤S206，输出可用时长。
示例性地，智能空调设置有显示单元，例如显示屏，通过显示屏显示该堵塞信息，以告知用户各出风单元的空调滤网的可用时长，例如，通过显示屏显示“可用时长为300小时”。从而使用户了解智能空调的滤网整体堵塞情况以及剩余使用寿命。或者将可用时长 发送至用户绑定的终端设备，以提醒用户进行滤网更换。
可选地，本实施例步骤还包括：输出每一空调滤网的堵塞信息。具体地，通过显示屏显示该堵塞信息，以告知用户各出风单元的空调滤网的堵塞程度，其中，输出堵塞信息的具体实现过程与输出可用时长的实现方式类似，此处不再赘述。
本实施例中，步骤S201的实现方式与本申请图2所示实施例中的步骤S101的实现方式相同，在此不再一一赘述。
