Description
技术领域technical field
本公开涉及终端设备技术领域，尤其涉及一种空气净化设备、滤芯的检测方法及装置。The present disclosure relates to the technical field of terminal equipment, and in particular to an air purification equipment and a detection method and device for a filter element.
背景技术Background technique
随着人们对空气质量的关注，空气净化设备在家庭、工作等场所中逐渐普及。空气净化设备中的滤芯可以对空气中的杂质例如PM2.5、PM3.0进行吸附过滤。随着空气净化设备的使用，滤芯表面吸附的杂质越来越多，从而使滤芯内外空气流通受阻，影响风量。滤芯将直接影响到空气净化效果，所以对滤芯的寿命进行检测对空气净化设备至关重要。With people's attention to air quality, air purification equipment is gradually popularized in homes, workplaces and other places. The filter element in the air purification equipment can adsorb and filter impurities in the air such as PM2.5 and PM3.0. With the use of air purification equipment, more and more impurities are adsorbed on the surface of the filter element, which hinders the air circulation inside and outside the filter element and affects the air volume. The filter element will directly affect the air purification effect, so it is very important to detect the life of the filter element for air purification equipment.
相关技术中，主要通过计算空气净化设备累计运行时间来估算滤芯剩余寿命，这种方法只是简单的将滤芯剩余寿命与运行时间对应起来，并在此基础上简单考虑或者不考虑空气质量的影响。由于空气净化设备所处环境的空气质量动态变化，空气质量对滤芯寿命的影响很大，且净化器风扇转速也会影响净化效果，因此这种方法并不能准确地反映出滤芯剩余寿命。In related technologies, the remaining life of the filter element is mainly estimated by calculating the cumulative running time of the air purification equipment. This method simply corresponds the remaining life of the filter element to the running time, and simply considers or does not consider the impact of air quality on this basis. Due to the dynamic change of the air quality in the environment where the air purification equipment is located, the air quality has a great impact on the life of the filter element, and the fan speed of the purifier will also affect the purification effect, so this method cannot accurately reflect the remaining life of the filter element.

The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
图1是根据一示例性实施例示出的一种空气净化设备的示意图。该空气净化设备可以应用于家庭、工作等场所中的空气净化，本实施例对此不作限制。如图1所示，该空气净化设备可以包括滤芯1、温度传感器2和滤芯的检测装置(图1中未示出)。其中，滤芯1可以为可拆卸滤芯，温度传感器2可以设置在空气净化设备的出风口侧，滤芯的检测装置可以根据空气净化设备中的温度传感器的温度变化率，确定滤芯的使用状态。Fig. 1 is a schematic diagram of an air cleaning device according to an exemplary embodiment. The air purification device may be applied to air purification in places such as homes and workplaces, which is not limited in this embodiment. As shown in FIG. 1 , the air purification device may include a filter element 1 , a temperature sensor 2 and a detection device for the filter element (not shown in FIG. 1 ). Wherein, the filter element 1 can be a detachable filter element, the temperature sensor 2 can be arranged on the air outlet side of the air purification equipment, and the detection device of the filter element can determine the use state of the filter element according to the temperature change rate of the temperature sensor in the air purification equipment.
本实施例的空气净化设备的工作原理为空气净化设备将空气吸入，滤芯1将被吸入的空气中的杂质例如PM2.5、PM3.0进行吸附过滤后再排出，由此实现净化空气的功能。空气净化设备可以具有进风口侧和出风口侧，其中，进风口侧可以为空气进入的一侧，出风口侧可以为空气排出的一侧。如图1所示，S1侧可以为空气净化设备的进风口侧，S2侧可以为空气净化设备的出风口侧。本实施例中的温度传感器2可以设置在空气净化设备的出风口侧。The working principle of the air purification equipment in this embodiment is that the air purification equipment sucks in air, and the filter element 1 absorbs and filters the impurities in the sucked air, such as PM2.5 and PM3.0, and then discharges them, thereby realizing the function of purifying the air . The air purification device may have an air inlet side and an air outlet side, wherein the air inlet side may be the side where air enters, and the air outlet side may be the side where air is discharged. As shown in FIG. 1 , the S1 side may be the air inlet side of the air purification device, and the S2 side may be the air outlet side of the air purification device. The temperature sensor 2 in this embodiment can be arranged on the side of the air outlet of the air purification device.
需要说明的是，本实施例不限制滤芯1的形状，例如可以为筒状滤芯或片状滤芯等。针对任何形状的滤芯1，温度传感器2设置在空气净化设备的出风口侧即可。本实施例不限制温度传感器2设置在空气净化设备的出风口侧的位置区域。作为本实施例的一个示例，如图1所示，温度传感器2可以设置在P1、P2和P3中的任一位置。It should be noted that the present embodiment does not limit the shape of the filter element 1 , for example, it may be a cylindrical filter element or a sheet filter element. For any shape of the filter element 1, the temperature sensor 2 can be arranged on the side of the air outlet of the air purification device. This embodiment does not limit the location where the temperature sensor 2 is disposed on the air outlet side of the air purification device. As an example of this embodiment, as shown in FIG. 1 , the temperature sensor 2 can be arranged at any position among P1 , P2 and P3 .
需要说明的是，本领域技术人员应当能够理解，滤芯的检测装置既可以为能够实现滤芯的检测功能的实体结构，也可以为能够实现滤芯的检测功能的软件程序，本实施例对此不作限制。It should be noted that those skilled in the art should be able to understand that the detection device of the filter element can be a physical structure capable of realizing the detection function of the filter element, or a software program capable of realizing the detection function of the filter element, which is not limited in this embodiment .
在一种可能的实现方式中，温度传感器的阻值随温度线性变化。In a possible implementation, the resistance of the temperature sensor changes linearly with temperature.
图2是根据一示例性实施例示出的一种空气净化设备的温度传感器的一示例性的电路示意图。作为本实施例的一个示例，温度传感器可以为采用铂热电阻(PT100)制作而成的温度传感器。如图2所示，温度传感器可以包括恒流源21和铂热电阻22，恒流源21与铂热电阻22之间可以形成串联连接的电气回路。Fig. 2 is an exemplary schematic circuit diagram of a temperature sensor of an air purification device according to an exemplary embodiment. As an example of this embodiment, the temperature sensor may be a temperature sensor made of a platinum thermal resistance (PT100). As shown in FIG. 2 , the temperature sensor may include a constant current source 21 and a platinum thermal resistance 22 , and an electrical circuit connected in series may be formed between the constant current source 21 and the platinum thermal resistance 22 .
其中，本示例的恒流源21可以为能够输出恒定电流I的电源。恒流源21输出的恒定电流I可以流经铂热电阻22，从而使得铂热电阻22加热升温。需要说明的是，本实施例不限制恒流源21所输出的恒定电流I的大小，在温度传感器的实际应用过程中，可以根据使用需求和使用场景进行选择确定。Wherein, the constant current source 21 in this example may be a power supply capable of outputting a constant current I. The constant current I output by the constant current source 21 can flow through the platinum thermal resistance 22 , so that the platinum thermal resistance 22 is heated up. It should be noted that this embodiment does not limit the magnitude of the constant current I output by the constant current source 21 , which can be selected and determined according to usage requirements and usage scenarios during the actual application of the temperature sensor.
在本示例中，铂热电阻22的阻值可以随着铂热电阻22的温度的变化而改变，且铂热电阻22的阻值与铂热电阻22的温度具有较好的线性关系。图3是根据相关技术示出的铂热电阻的阻值与铂热电阻的温度之间的关系示意图。如图3所示，铂热电阻22的阻值可以随着铂热电阻22的温度的上升而呈现近似均匀的增长，由此可以通过测量铂热电阻22的阻值而确定铂热电阻22的温度，并可以确定铂热电阻22的温度变化率，也即可以确定温度传感器的温度变化率。In this example, the resistance value of the platinum thermal resistor 22 can change with the temperature of the platinum thermal resistor 22 , and the resistance value of the platinum thermal resistor 22 has a good linear relationship with the temperature of the platinum thermal resistor 22 . Fig. 3 is a schematic diagram showing the relationship between the resistance value of the platinum thermal resistance and the temperature of the platinum thermal resistance according to the related art. As shown in Figure 3, the resistance value of the platinum thermal resistance 22 can present approximately uniform growth along with the rise of the temperature of the platinum thermal resistance 22, thus the resistance value of the platinum thermal resistance 22 can be determined by measuring the resistance value of the platinum thermal resistance 22 temperature, and the temperature change rate of the platinum thermal resistance 22 can be determined, that is, the temperature change rate of the temperature sensor can be determined.
在空气净化设备中能够影响铂热电阻22的温度变化率的主要因素可以包括空气净化设备的出风口侧的空气对流大小，即风量大小，由此可以通过检测铂热电阻22的温度变化率实现检测空气净化设备的出风口侧的风量大小。在空气净化设备以相同转速工作的情况下，若滤芯1已经吸附过滤较多杂质，则通过滤芯1的风量可能会相对较小，若滤芯1为全新未使用过的状态，则通过滤芯1的风量则可能会相对较大。因此，将温度传感器应用到空气净化设备中，可以通过空气净化设备的出风口侧的风量大小的变化，实现对滤芯1剩余寿命的检测。The main factors that can affect the temperature change rate of the platinum thermal resistance 22 in the air purification equipment can include the air convection on the air outlet side of the air purification equipment, that is, the air volume, which can be realized by detecting the temperature change rate of the platinum thermal resistance 22 Detect the air volume on the air outlet side of the air purification equipment. When the air purification equipment works at the same speed, if the filter element 1 has adsorbed and filtered more impurities, the air volume passing through the filter element 1 may be relatively small; The air volume may be relatively large. Therefore, applying the temperature sensor to the air purification device can detect the remaining life of the filter element 1 through the change of the air volume at the air outlet side of the air purification device.
图4是根据一示例性实施例示出的一种滤芯的检测方法的流程图。该滤芯的检测方法可以应用于空气净化器等空气净化设备，本实施例对此不作限制。如图4所示，该滤芯的检测方法，可以包括以下步骤。Fig. 4 is a flow chart of a method for detecting a filter element according to an exemplary embodiment. The detection method of the filter element can be applied to air purification equipment such as an air purifier, which is not limited in this embodiment. As shown in Fig. 4, the detection method of the filter element may include the following steps.
在步骤S401中，确定空气净化设备中的温度传感器的温度变化率，温度传感器设置在空气净化设备的出风口侧。In step S401, the temperature change rate of the temperature sensor in the air purification device is determined, and the temperature sensor is arranged at the air outlet side of the air purification device.
本实施例的温度变化率可以为温度传感器的温度变化值与温度变化值对应的时长的比值。需要说明的是，本领域技术人员应当能够理解，相关技术中有多种方式可以实现确定空气净化设备的出风口侧的温度变化率，上述的通过温度传感器确定空气净化设备的出风口侧的温度变化率只是众多方式中的一种，本实施例对此不作限制。The temperature change rate in this embodiment may be a ratio of the temperature change value of the temperature sensor to the time length corresponding to the temperature change value. It should be noted that those skilled in the art should be able to understand that there are many ways in the related art to determine the temperature change rate of the air outlet side of the air purification equipment, and the above-mentioned temperature sensor is used to determine the temperature of the air outlet side of the air purification equipment. The rate of change is only one of many modes, which is not limited in this embodiment.
需要说明的是，本领域技术人员应当能够理解，空气净化设备可以具有一档或多档工作状态。在空气净化设备具有多档工作状态的情况下，空气净化设备处于不同档工作状态，可以指空气净化设备以不同马达转速工作，从而使得空气净化设备的出风口侧的风量大小不同。It should be noted that those skilled in the art should be able to understand that the air purification equipment can have one or more working states. In the case that the air purification device has multiple working states, the air purification device is in different working states, which may mean that the air purification device works at different motor speeds, so that the air volume of the air outlet side of the air purification device is different.
作为本实施例的一个示例，在空气净化设备具有多档工作状态的情况下，确定空气净化设备中的温度传感器的温度变化率，可以包括：在空气净化设备处于固定档工作状态的情况下，确定空气净化设备中的温度传感器的温度变化率。例如，在空气净化设备具有三档(大档、中档和小档)工作状态的情况下，可以在空气净化设备处于中档工作状态的情况下，确定空气净化设备中的温度传感器的温度变化率。As an example of this embodiment, when the air purification device has multiple working states, determining the temperature change rate of the temperature sensor in the air purification device may include: when the air purification device is in a fixed gear working state, Determine the rate of temperature change of a temperature sensor in an air cleaning device. For example, when the air purification device has three working states (high, middle and small), the temperature change rate of the temperature sensor in the air cleaning device can be determined when the air cleaning device is in the middle working state.
在步骤S402中，根据该温度变化率确定滤芯的使用状态。In step S402, the use state of the filter element is determined according to the temperature change rate.
滤芯的使用状态可以指能够代表滤芯使用程度或剩余寿命的信息。其中，滤芯的使用状态既可以是定性信息，例如滤芯的使用状态可以为未使用状态、可使用状态或用尽状态等。滤芯的使用状态也可以是定量信息，例如滤芯的使用状态可以为滤芯的剩余寿命为32％，或滤芯的剩余寿命为30％至40％等。The usage status of the filter element may refer to information that can represent the degree of use or the remaining life of the filter element. Wherein, the use state of the filter element may be qualitative information, for example, the use state of the filter element may be an unused state, a usable state, or an exhausted state. The usage status of the filter element may also be quantitative information, for example, the usage status of the filter element may be 32% of the remaining life of the filter element, or 30% to 40% of the remaining life of the filter element.
在一种可能的实现方式中，根据该温度变化率确定滤芯的使用状态，包括：在该温度变化率大于或等于第一阈值的情况下，确定滤芯的使用状态为第一状态；在该温度变化率大于或等于第二阈值且小于第一阈值的情况下，确定滤芯的使用状态为第二状态；在该温度变化率小于第二阈值的情况下，确定滤芯的使用状态为第三状态。In a possible implementation manner, determining the use state of the filter element according to the temperature change rate includes: determining that the use state of the filter element is the first state when the temperature change rate is greater than or equal to a first threshold; When the rate of change is greater than or equal to the second threshold and less than the first threshold, it is determined that the use state of the filter element is the second state; when the temperature change rate is less than the second threshold, it is determined that the use state of the filter element is the third state.
作为该实现方式的一个示例，在空气净化设备具有多档工作状态的情况下，可以根据空气净化设备的工作状态，确定第一阈值和第二阈值。例如，在空气净化设备处于中档工作状态的情况下，可以确定中档工作状态对应的第一阈值和第二阈值。As an example of this implementation, in the case that the air purification device has multiple operating states, the first threshold and the second threshold may be determined according to the operating states of the air purification device. For example, when the air purification device is in a mid-range working state, the first threshold and the second threshold corresponding to the mid-range working state may be determined.
需要说明的是，本领域技术人员应当能够理解，第一阈值和第二阈值与空气净化设备的工作状态以及滤芯的型号具有对应关系。其中，空气净化设备的工作状态可以包括例如空气净化设备以马达转速η1工作，或以马达转速η2工作等。滤芯的型号可以指能够表示滤芯过滤能力的型号。在实际的应用过程中，本实施的第一阈值和第二阈值可以根据本领域技术人员的经验设置，例如可以通过实验进行标定，本实施例对此不作限制。It should be noted that those skilled in the art should be able to understand that the first threshold and the second threshold have a corresponding relationship with the working state of the air purification device and the model of the filter element. Wherein, the working state of the air cleaning device may include, for example, that the air cleaning device works at a motor speed of η1, or at a motor speed of η2 , and the like. The model of the filter element may refer to a model that can represent the filtration capacity of the filter element. In an actual application process, the first threshold and the second threshold in this implementation may be set according to experience of those skilled in the art, for example, may be calibrated through experiments, which is not limited in this embodiment.
图5是根据一示例性实施例示出的温度变化率和马达转速之间的一示例性的关系示意图。作为本实施例的一个示例，可以针对马达转速η的空气净化设备，第一型号滤芯标定第一阈值为τ1，第二阈值为τ3。如图5所示，在温度变化率大于或等于第一阈值τ1的情况下，可以确定滤芯的使用状态为未使用状态(第一状态)，即为全新滤芯。在温度变化率大于或等于第二阈值τ3且小于第一阈值τ1的情况下，可以确定滤芯的使用状态为可使用状态(第二状态)，即为能够使用的非全新滤芯。在温度变化率小于第二阈值τ3的情况下，可以确定滤芯的使用状态为用尽状态(第三状态)，即为报废滤芯。Fig. 5 is a schematic diagram showing an exemplary relationship between the temperature change rate and the motor speed according to an exemplary embodiment. As an example of this embodiment, for an air purification device with a motor speed of η, the filter element of the first type is calibrated with a first threshold value of τ1 and a second threshold value of τ3. As shown in FIG. 5 , when the rate of temperature change is greater than or equal to the first threshold τ1 , it can be determined that the filter element is in an unused state (first state), that is, it is a brand new filter element. When the temperature change rate is greater than or equal to the second threshold τ3 and less than the first threshold τ1, it can be determined that the use state of the filter element is a usable state (second state), that is, a non-new filter element that can be used. In the case that the temperature change rate is less than the second threshold τ3, it can be determined that the use state of the filter element is an exhausted state (third state), that is, the filter element is discarded.
此外，还可以在第一阈值τ1和第二阈值τ3之间设置第三阈值为τ2，在温度变化率大于第三阈值τ2的情况下，可以确定滤芯的剩余寿命大于50％，而在温度变化率小于第三阈值τ2的情况下，可以确定滤芯的剩余寿命小于50％。In addition, the third threshold value τ2 can also be set between the first threshold value τ1 and the second threshold value τ3. When the temperature change rate is greater than the third threshold value τ2, it can be determined that the remaining life of the filter element is greater than 50%. When the rate is less than the third threshold τ2, it can be determined that the remaining life of the filter element is less than 50%.
在一种可能的实现方式中，根据该温度变化率确定滤芯的使用状态，包括：根据温度变化率与使用状态之间的对应关系，以及温度传感器的温度变化率，确定滤芯的使用状态。In a possible implementation manner, determining the use state of the filter element according to the temperature change rate includes: determining the use state of the filter element according to the correspondence between the temperature change rate and the use state, and the temperature change rate of the temperature sensor.
作为该实现方式的一个示例，在空气净化设备具有多档工作状态的情况下，可以根据空气净化设备的工作状态，确定温度变化率与使用状态之间的对应关系。例如，在空气净化设备处于中档工作状态的情况下，可以确定中档工作状态对应的温度变化率与使用状态之间的对应关系。As an example of this implementation, in the case that the air purification device has multiple working states, the correspondence between the temperature change rate and the usage state may be determined according to the working state of the air cleaning device. For example, when the air purification device is in a mid-range working state, the corresponding relationship between the temperature change rate corresponding to the mid-range working state and the use state may be determined.
通过本示例的方法，可以直接根据温度变化率确定滤芯的剩余寿命的数值或范围，例如确定滤芯的剩余寿命为32％，或确定滤芯的剩余寿命为30％至40％。需要说明的是，本领域技术人员应当能够理解，温度变化率与使用状态之间的对应关系与空气净化设备的工作状态以及滤芯的型号具有对应关系。在实际的应用过程中，本实施的温度变化率与使用状态之间的对应关系可以根据本领域技术人员的经验设置，例如可以通过实验进行标定，本实施例对此不作限制。Through the method of this example, the value or range of the remaining life of the filter element can be directly determined according to the temperature change rate, for example, the remaining life of the filter element is determined to be 32%, or the remaining life of the filter element is determined to be 30% to 40%. It should be noted that those skilled in the art should be able to understand that the corresponding relationship between the temperature change rate and the usage status has a corresponding relationship with the working status of the air purification equipment and the model of the filter element. In the actual application process, the corresponding relationship between the temperature change rate and the use state in this embodiment can be set according to the experience of those skilled in the art, for example, it can be calibrated through experiments, which is not limited in this embodiment.
本实施例的滤芯的检测方法，通过确定空气净化设备中的温度传感器的温度变化率，并根据温度变化率确定滤芯的使用状态，由此能够对滤芯的使用状态进行检测，并能够准确判断滤芯的剩余寿命，且实现难度较小。The detection method of the filter element in this embodiment determines the temperature change rate of the temperature sensor in the air purification equipment, and determines the use state of the filter element according to the temperature change rate, so that the use state of the filter element can be detected, and the filter element can be accurately judged The remaining life of the , and the implementation is less difficult.
图6是根据一示例性实施例示出的一种滤芯的检测方法中步骤S401的一示例性的流程图。如图6所示，确定空气净化设备中的温度传感器的温度变化率(步骤S401)，可以包括以下步骤。Fig. 6 is an exemplary flow chart of step S401 in a method for detecting a filter element according to an exemplary embodiment. As shown in FIG. 6 , determining the temperature change rate of the temperature sensor in the air purification device (step S401 ) may include the following steps.
在步骤S600中，确定第一温度和第二温度，其中，第一温度大于第二温度。In step S600, a first temperature and a second temperature are determined, wherein the first temperature is greater than the second temperature.
在步骤S601中，控制温度传感器达到第一温度。In step S601, the temperature sensor is controlled to reach a first temperature.
本实施例不限制第一温度的数值，例如可以根据空气净化设备所处环境的温度设定第一温度。This embodiment does not limit the value of the first temperature, for example, the first temperature may be set according to the temperature of the environment where the air purification device is located.
需要说明的是，本领域技术人员应当能够理解，相关技术中有多种方式可以实现控制温度传感器达到第一温度，例如对温度传感器进行导电加热，本实施例对此不作限制。It should be noted that those skilled in the art should be able to understand that there are many ways in the related art to control the temperature sensor to reach the first temperature, such as conducting conductive heating on the temperature sensor, which is not limited in this embodiment.
在步骤S602中，启动空气净化设备的空气净化功能，并确定温度传感器从第一温度达到第二温度的第一时长。In step S602, start the air cleaning function of the air cleaning device, and determine the first time period for the temperature sensor to reach the second temperature from the first temperature.
可以理解的是，在温度传感器第一次到达第一温度之后还可能有一小段的温度上升，因此在温度传感器降温且第二次到达第一温度时开始计时，并在温度传感器降温且第一次到达第二温度时停止计时，从而确定第一时长。It can be understood that there may be a short period of temperature rise after the temperature sensor reaches the first temperature for the first time, so start timing when the temperature sensor cools down and reaches the first temperature for the second time, and when the temperature sensor cools down and reaches the first temperature for the first time Stop timing when the second temperature is reached, so as to determine the first duration.
需要说明的是，本实施例不限制启动空气净化设备的空气净化功能的时刻，即在温度传感器降温且第二次到达第一温度之前启动即可。It should be noted that this embodiment does not limit the timing of starting the air cleaning function of the air cleaning device, that is, it only needs to be started before the temperature sensor cools down and reaches the first temperature for the second time.
在步骤S603中，根据第一温度、第二温度和第一时长，确定温度传感器的温度变化率。In step S603, the temperature change rate of the temperature sensor is determined according to the first temperature, the second temperature and the first time period.

Δτ＝(T1-T2)/Δt 式1；Δτ=(T 1 -T 2 )/Δt Formula 1;
其中，T1表示第一温度，T2表示第二温度，Δt表示第一时长。Wherein, T 1 represents the first temperature, T 2 represents the second temperature, and Δt represents the first duration.
图7是根据一示例性实施例示出的温度和时间之间的一示例性的关系示意图。作为本实施例的一个示例，如图7所示，启动恒流源21输出恒定电流I，使得铂热电阻22加热升温至第一温度T1。关闭恒流源21，并启动空气净化设备的空气净化功能，例如以马达转速η工作。由于铂热电阻22在第一次到达第一温度T1之后还有一小段的温度上升，因此在铂热电阻22降温且第二次到达第一温度T1时开始计时，例如为t1时刻，并在铂热电阻22第一次到达第二温度T2时停止计时，例如为t2时刻，可以得到第一时长为Δt＝t2-t1。温度传感器的温度变化率为线性变化，因此根据第一温度T1、第二温度T2和第一时长Δt，可以采用式1确定温度传感器的温度变化率。需要说明的是，本实施例不限制启动空气净化设备的空气净化功能的时刻，在铂热电阻22降温且第二次到达第一温度T1之前启动即可。Fig. 7 is a schematic diagram showing an exemplary relationship between temperature and time according to an exemplary embodiment. As an example of this embodiment, as shown in FIG. 7 , the constant current source 21 is started to output a constant current I, so that the platinum thermal resistor 22 is heated to a first temperature T 1 . Close the constant current source 21, and start the air cleaning function of the air cleaning equipment, for example, work with the motor speed η. Since the platinum thermal resistance 22 also has a short period of temperature rise after reaching the first temperature T1 for the first time, it starts counting when the platinum thermal resistance 22 cools down and reaches the first temperature T1 for the second time, for example, at time t1 , And the timing is stopped when the platinum thermal resistance 22 reaches the second temperature T 2 for the first time, for example at time t 2 , and the first time length can be obtained as Δt=t 2 −t 1 . The temperature change rate of the temperature sensor changes linearly, so according to the first temperature T 1 , the second temperature T 2 and the first time period Δt, formula 1 can be used to determine the temperature change rate of the temperature sensor. It should be noted that this embodiment does not limit the timing of starting the air cleaning function of the air cleaning device, and it only needs to be started before the platinum thermal resistance 22 cools down and reaches the first temperature T1 for the second time.
本实施例的滤芯的检测方法，采用温度变化率为线性变化的温度传感器，能够通过设定第一温度和第二温度，并测量空气净化设备进行空气净化时温度传感器从第一温度达到第二温度的第一时长，实现确定温度传感器的温度变化率，由此能够对滤芯的使用状态进行检测，并能够准确判断滤芯的剩余寿命，且实现难度较小。The detection method of the filter element of this embodiment adopts a temperature sensor whose temperature change rate changes linearly, and can reach the second temperature from the first temperature by setting the first temperature and the second temperature, and measuring the temperature sensor when the air purification equipment performs air purification. The first duration of the temperature is used to determine the temperature change rate of the temperature sensor, so that the use status of the filter element can be detected, and the remaining life of the filter element can be accurately judged, and the implementation is less difficult.

在步骤S801中，确定温度传感器所处环境的第三温度。In step S801, a third temperature of the environment where the temperature sensor is located is determined.
作为本实施例的一个示例，测量铂热电阻22在初始环境下的阻值，通过查温度阻值表或计算得到铂热电阻22的初始温度T3，即温度传感器所处环境的第三温度T3。As an example of this embodiment, measure the resistance value of the platinum thermal resistance 22 in the initial environment, and obtain the initial temperature T 3 of the platinum thermal resistance 22 by checking the temperature resistance table or calculation, that is, the third temperature of the environment where the temperature sensor is located T3 .
在步骤S802中，根据第三温度，确定第一温度和第二温度，其中，第二温度大于第三温度，第一温度大于第二温度。In step S802, a first temperature and a second temperature are determined according to the third temperature, wherein the second temperature is greater than the third temperature, and the first temperature is greater than the second temperature.
需要说明的是，本领域技术人员应当能够理解，相关技术中有多种方式可以实现根据第三温度确定第一温度和第二温度，例如可以通过实验进行标定，本实施例对此不作限制。It should be noted that those skilled in the art should be able to understand that there are many ways in the related art to determine the first temperature and the second temperature according to the third temperature, such as calibration through experiments, which is not limited in this embodiment.
