[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0059] Air conditioning and other fresh air systems are already common equipment in production and daily life. The filters in these systems remove dust and harmful substances from the air, directly affecting air quality. The filtration efficiency of the filters directly affects the performance of the equipment. Some filters with powerful functions (such as air purification) cannot be washed and can only be replaced after a certain period of use. However, users often find it difficult to determine when to replace the filters.

[0060] Existing traditional air conditioning equipment and fresh air conditioners on the market do not have a solution for accurately estimating the lifespan of filters or filter screens, often resulting in filters operating beyond their effective lifespan due to overload.

[0061] In air purifier solutions, RFID (Radio Frequency Identification) is commonly used. This involves reading and writing information from the RFID chip on the filter to verify its lifespan and prevent counterfeiting. However, this process often requires intervention from the manufacturer or service provider, making it difficult for users to verify the information themselves and hindering timely filter replacement.

[0062] This disclosure provides a method for determining the lifespan of a filter. This method is applied to a fresh air system. A battery is installed inside the filter of the fresh air system, along with a discharge circuit. Based on the battery voltage and the discharge state of the discharge circuit, the remaining service life of the filter can be determined. This allows for real-time monitoring of the remaining lifespan of the filter according to the operating status of the fresh air system, enabling timely replacement of the filter and ensuring the operating effect of the fresh air system and the user experience.

[0063] It should be noted that the fresh air equipment involved in this disclosure includes ventilation equipment, that is, equipment that only has the function of gas transportation, such as air supply equipment; it also includes equipment with functions such as gas humidification, dehumidification or purification, such as air conditioners with air purification functions.

[0064] Figure 1 This is a flowchart of a method for determining the lifespan of a filter screen according to an exemplary embodiment of this disclosure, with reference to... Figure 1 As shown, the method includes the following steps:

[0065] Step S100: Obtain the operating status information of the fresh air equipment;

[0066] Step S200: Determine the discharge circuit of the battery installed in the filter screen based on the operating status information;

[0067] Step S300: Connect the discharge circuit to allow the battery to discharge according to a preset discharge state;

[0068] Step S400: Determine the remaining usage time of the filter screen according to the preset discharge state.

[0069] The method for determining the lifespan of a filter provided in this embodiment involves placing a battery inside the filter, adapting the battery's discharge circuit to the operating state of the fresh air system, determining the battery's discharge circuit based on the operating state information of the fresh air system, and then determining the remaining discharge time of the battery based on the battery's discharge state, thereby determining the remaining usage time of the filter. This allows for accurate calculation of the remaining lifespan of the filter, facilitating timely filter replacement and ensuring the effective operation of the fresh air system.

[0070] Figure 2 This is a schematic diagram of the interior of a fresh air system 500 according to an exemplary embodiment, with reference to... Figure 2 As shown, a fresh air system 500 applying the filter life determination method of this disclosure includes: a filter 510, an indoor unit structure 520, multiple discharge circuits 530, and a microcontroller 540. The filter 510 contains a battery 511, which is connected to the indoor unit structure 520 after installation. The battery 511 is connected to the discharge circuits 530. The microcontroller 540 controls the conduction of at least one of the discharge circuits 530 during operation of the fresh air system 500.

[0071] The discharge resistances of the multiple discharge circuits 530 are not exactly the same, and the discharge resistance of each discharge circuit 530 is adapted to a certain operating state of the fresh air equipment.

[0072] The built-in battery 511 can be discharged through the discharge circuit 530 to accurately calculate the remaining usage time of the filter 510, and can also be used for anti-counterfeiting purposes.

[0073] During the operation of the fresh air system 500, the corresponding discharge circuit 530 is determined and connected based on the operating status information of the fresh air system 500, so that the battery 511 discharges according to the preset discharge state, and the discharge time of the battery 511 under the preset discharge state is calculated. Based on this, the remaining service life of the filter 510 can be determined. The remaining lifespan of the filter 510 can be accurately calculated so that the filter 510 can be replaced in a timely manner, ensuring the operating effect of the fresh air system 500 and improving the user experience.

[0074] In step S100, the operating status information of the fresh air device is obtained, including the fan speed level information of the fresh air device, that is, the current operating level of the fresh air device, such as low, medium, high, ultra-high, etc., and the fan speed information of the fresh air device at the current operating level is determined based on the level information. If the fresh air device includes purification functions such as dust removal, for example, it can handle PM2.5 particles in the air, then the operating status information of the fresh air device may also include purification level information, such as low, medium, high, ultra-high, etc.

[0075] In some embodiments, the operating status information of the fresh air device can be reacquired at preset intervals to promptly detect changes in the operating status of the fresh air device. Based on the changed operating status information, the battery discharge circuit can be re-discharged to redetermine the remaining usage time of the filter, thereby ensuring accurate calculation of the filter's lifespan and timely replacement of the filter, thus improving the user experience.

[0076] In step S200, the discharge circuit of the battery installed inside the filter is determined based on the operating status information.

[0077] The principle of this disclosure is to install a battery inside the filter and set up different discharge circuits according to different operating states, so that the discharge time of the battery in each operating state is adapted to the service life of the filter. Thus, the remaining service life of the filter can be determined based on the remaining discharge time of the battery in the current operating state.

[0078] For example, a corresponding discharge circuit is set up for each different fan speed setting of the fresh air device. For instance, a first sub-discharge circuit is set up for the low fan speed setting; a second sub-discharge circuit is set up for the medium fan speed setting; a third sub-discharge circuit is set up for the high fan speed setting; and a fourth sub-discharge circuit is set up for the ultra-high fan speed setting. The discharge resistance value of each discharge circuit is related to the fan speed corresponding to the specified fan speed setting.

[0079] For fresh air systems that include purification functions such as dust removal, discharge circuits corresponding to each purification level are also provided. For example, a fifth sub-discharge circuit is provided for the low purification level; a sixth sub-discharge circuit is provided for the medium purification level; a seventh sub-discharge circuit is provided for the high purification level; and an eighth sub-discharge circuit is provided for the ultra-high purification level. The discharge resistance value of each discharge circuit is related to the purification intensity corresponding to the specified purification level.

[0080] In this disclosure, the discharge resistances of the discharge circuits corresponding to different operating states may be the same or different. For example, the discharge resistance of the first sub-discharge circuit may be the same as or different from the resistance value of the first sub-purification circuit. The discharge resistance value of each discharge circuit is related to the degree of consumption or use of the filter screen under its corresponding operating state.

[0081] Therefore, the battery discharge circuit can be determined based on the operating status information of the fresh air system.

[0082] In step S300, the discharge circuit determined in step S200 is connected so that the battery discharges according to a preset discharge state, thereby matching the preset discharge state with the operating state of the fresh air equipment.

[0083] For example, if the operating status information of the fresh air device is at the high fan speed setting, then in step S200, it can be determined that the battery discharge circuit is the third sub-discharge circuit, and then in step S300, the third sub-discharge circuit can be connected.

[0084] If the fresh air system includes a purification function and the purification function is activated in the current operating state, its operating status information includes fan speed level information and purification level information. For example, if the fresh air system's operating status information includes a high fan speed level and a medium purification level, then in step S200, the battery discharge circuit is determined to be the third sub-discharge circuit and the sixth sub-discharge circuit. Therefore, in step S300, both the third sub-discharge circuit and the sixth sub-discharge circuit need to be connected simultaneously.

[0085] In step S400, the remaining usage time of the filter is determined based on the discharge state of the discharge circuit connected in step S300.

[0086] In this disclosure, the discharge circuit connected in step S300 is the discharge circuit of the battery during the operation of the fresh air equipment. Therefore, based on the discharge state of this discharge circuit, the remaining discharge time of the battery in this discharge state can be determined, and thus the remaining usage time of the filter can be determined.

[0087] The method for determining filter lifespan provided in this disclosure can determine the filter's battery discharge circuit based on the operating status of the fresh air system, then determine the remaining discharge time of the battery based on the battery discharge status, and finally determine the remaining usage time of the filter. This enables real-time monitoring of the filter's lifespan and allows for timely filter replacement. For example, an alarm module can be installed on fresh air systems such as air conditioners to issue a warning when the remaining usage time of the filter is less than a preset value, prompting the user to prepare to replace the filter. Alternatively, a display module can be installed on the fresh air system or a smart terminal such as a mobile phone connected to the system to display the remaining usage time of the filter in real time for easy viewing by the user. For example, the filter's operating status information and remaining usage time can be viewed on a relevant mobile app.

[0088] In some embodiments, the discharge duration of the discharge circuit is positively correlated with the usage time of the filter. That is, as the fresh air system operates, the filter is continuously in use, and the filter's battery discharges in real time according to the discharge circuit corresponding to the operating status information. Therefore, the usage time of the filter is positively correlated with the discharge duration of the connected discharge circuit. In other words, the remaining discharge time of the battery in the discharge state of the connected discharge circuit is positively correlated with the remaining usage time of the filter.

[0089] For example, the remaining usage time of the filter can be equal to or a multiple of the remaining discharge time of the battery.

[0090] Figure 3 A flowchart illustrating one implementation of step S400 is shown, with reference to... Figure 3 As shown, in some embodiments, the remaining usage time of the filter is determined according to a preset discharge state, including:

[0091] Step S410: Obtain the remaining voltage of the battery;

[0092] Step S420: Determine the remaining usage time of the filter screen based on the remaining battery voltage and the discharge parameters of the discharge circuit.

[0093] In this disclosure, as the fresh air system operates, the filter's battery continuously and stably discharges through the discharge circuit, causing the battery voltage to gradually decrease and the remaining usage time of the filter to gradually decrease. The filter's lifespan is adapted to the battery's discharge lifespan; therefore, the filter's remaining usage time can be determined based on the battery's remaining discharge time in its current discharge state.

[0094] By obtaining the battery's remaining voltage and using it along with the discharge parameters of the discharge circuit, the remaining discharge time of the battery under the current discharge circuit can be determined, thereby determining the remaining usage time of the filter. The discharge parameters of the discharge circuit include the discharge resistance of the discharge circuit.

[0095] In some embodiments, when the fresh air equipment does not include dust removal or other purification functions, or when the purification function is not turned on, its operating status information only includes the fan speed setting information.

[0096] Figure 4 This is a flowchart illustrating step S200 in an exemplary embodiment. In this embodiment, determining the discharge circuit of the battery disposed within the filter screen based on the operating status information includes:

[0097] Step S210: Determine the first discharge circuit based on the preset wind speed setting information.

[0098] The first discharge circuit includes a first discharge resistor, which is positively correlated with the wind speed corresponding to the preset wind speed setting.

[0099] In this embodiment, the fresh air device operates at a preset fan speed setting, meaning the airflow speed passing through the filter is at this preset speed setting. Simultaneously, the battery discharges through the first discharge circuit. A higher fan speed at the preset setting results in higher efficiency of air passing through the filter, leading to greater filter consumption. Correspondingly, a higher discharge efficiency of the first discharge circuit results in a larger discharge resistor value, ensuring a positive correlation between the battery's discharge time and the filter's usage time.

[0100] In some embodiments, the fresh air system activates purification functions such as dust removal. In this case, its operating status information also includes purification level information. That is, the fresh air system operates with both fan speed and purification levels activated simultaneously. At this time, the battery discharges based on both fan speed and purification level information.

[0101] Figure 5 This is a flowchart illustrating the implementation of step S200 when activating the purification function according to an exemplary embodiment. (Refer to...) Figure 5 As shown, in this embodiment, the discharge circuit of the battery installed inside the filter is determined based on the operating status information, including:

[0102] Step S210: Determine the first discharge circuit based on the preset wind speed setting information.

[0103] Step S220: Determine the second discharge circuit based on the preset purification level information.

[0104] As described above, the first discharge circuit includes a first discharge resistor, which is positively correlated with the wind speed corresponding to the preset wind speed level; correspondingly, the second discharge circuit includes a second discharge resistor, which is positively correlated with the purification index of the preset purification level.

[0105] In this disclosure, the first discharge circuit and the second discharge circuit do not interfere with each other, and their determination criteria are different, but they can discharge simultaneously. For example, when the low fan speed setting is turned on, the first sub-discharge circuit can be determined as the first discharge circuit; at the same time, when the ultra-high purification setting is turned on, the eighth sub-discharge circuit can be determined as the second discharge circuit. As another example, when the ultra-high fan speed setting is turned on and the fourth sub-discharge circuit is determined as the first discharge circuit, the medium purification setting can be turned on and the sixth sub-discharge circuit can be determined as the second discharge circuit.

[0106] When the fresh air system is turned on and running at the preset fan speed, if the purification function is also activated, it will purify the air at the preset purification level, for example, the high-power purification setting. In this case, the second discharge circuit becomes the seventh sub-discharge circuit. The higher the purification index of the preset purification level, the better the purification effect of the fresh air system, but the greater the wear and tear on the filter. Therefore, the demand for battery discharge is greater. Consequently, the second discharge resistor in the second discharge circuit is positively correlated with the purification index of the preset purification level.

[0107] The selection of the purification level during the operation of a fresh air system can be determined based on the air quality index of the environment in which the system is located. For example, the worse the air quality, the higher the purification index corresponding to the preset purification level needs to be. For instance, taking PM2.5 as an example, a higher PM2.5 air quality index indicates worse air quality and a higher demand for air purification, requiring the activation of a high-power purification level, or even an ultra-high-power purification level. Correspondingly, the required discharge resistance value for the second discharge circuit also needs to be higher.

[0108] Figure 6 A flowchart illustrating the implementation of step S220 in one embodiment is shown, with reference to... Figure 6 As shown, in this embodiment, the second discharge circuit is determined based on the preset purification level information, including:

[0109] Step S221: Obtain the ambient air quality index;

[0110] Step S222: Determine the preset purification level based on the ambient air quality index;

[0111] Step S223: Determine the second discharge circuit according to the preset purification level.

[0112] In one exemplary embodiment, the ambient air index may also include ambient air humidity, and the purification function includes dehumidification. The higher the ambient air humidity, the greater the demand for dehumidification; therefore, the higher the preset purification level is determined, and consequently, the higher the second discharge resistance corresponding to the second discharge circuit is determined.

[0113] In some embodiments, when the fresh air system's purification function is activated, the remaining usage time of the filter is determined based on the remaining battery voltage and the discharge parameters of the discharge circuit, including:

[0114] The remaining usage time of the filter is determined based on the remaining battery voltage, the discharge parameters of the first discharge circuit, and the discharge parameters of the second discharge circuit.

[0115] For example, the remaining discharge time of the battery in the current operating state is determined based on the remaining voltage of the battery, the first discharge resistor, and the second discharge resistor, and then the remaining usage time of the filter is determined.

[0116] The method for determining the lifespan of a filter provided in this embodiment determines the corresponding discharge circuit based on the fan speed and purification settings of the fresh air system, thereby controlling the corresponding discharge of the battery inside the filter. Based on the battery's discharge state, the remaining discharge time of the battery is determined, and thus the remaining usable time of the filter is determined, facilitating timely filter replacement by the user, ensuring the performance of the fresh air system, and improving the user experience.

[0117] This disclosure also provides a device for determining the lifespan of a filter, applied to a fresh air system, so that users can replace the filter of the fresh air system in a timely manner. Figure 7 A schematic diagram of a device 600 for determining the lifespan of the filter screen is shown, with reference to... Figure 7 As shown, the filter lifespan determination device 600 includes: an acquisition module 610, a first determination module 620, a discharge module 630, and a second determination module 640. Among them,

[0118] The acquisition module 610 is configured to acquire the operating status information of the fresh air equipment;

[0119] The first determining module 620 is configured to determine the discharge circuit of the battery set inside the filter screen based on the operating status information.

[0120] The discharge module 630 is configured to connect to the discharge circuit so that the battery discharges according to a preset discharge state.

[0121] The second determining module 640 is configured to determine the remaining usage time of the filter screen based on a preset discharge state.

[0122] The filter life determination device disclosed herein includes a first determining module 620 which determines the discharge circuit of the filter battery based on the operating status information of the fresh air equipment obtained by the acquiring module 610, and a discharge module 630 which connects the corresponding discharge circuit according to the determination result of the first determining module 620, so that the battery discharges according to a preset discharge state; and a second determining module 640 which determines the remaining discharge time of the battery based on the discharge state of the battery, thereby determining the remaining usage time of the filter.

[0123] By installing a battery inside the filter and linking the battery's discharge circuit to the filter's consumption under different operating conditions, the remaining usage time of the filter can be determined using the battery's available time. This allows for effective and accurate monitoring of the filter's lifespan, enabling users to replace the filter in a timely manner and improving the user experience.

[0124] In some embodiments of this disclosure, the discharge duration of the discharge circuit is positively correlated with the usage time of the filter. As the fresh air system operates, the filter is continuously in use, and the filter's battery discharges in real time according to the discharge circuit corresponding to the operating status information. Therefore, the usage time of the filter is positively correlated with the discharge duration of the connected discharge circuit. In other words, the remaining discharge time of the battery in the discharge state of the connected discharge circuit is positively correlated with the remaining usage time of the filter. Exemplarily, the remaining usage time of the filter and the remaining discharge time of the battery can be equal or a multiple thereof.

[0125] In some embodiments, the second determining module 640 includes an acquiring unit 641 and a determining unit 642, wherein,

[0126] The acquisition unit 641 is configured to acquire the remaining voltage of the battery;

[0127] The determining unit 642 is configured to determine the remaining usage time of the filter based on the remaining voltage of the battery and the discharge parameters of the discharge circuit.

[0128] In some embodiments, when the fresh air device does not include dust removal or other purification functions, or when the purification function is not activated, its operating status information only includes fan speed information. In this case, the first determining module 620 is configured to determine a first discharge circuit based on a preset fan speed level in the fan speed information. The first discharge circuit includes a first discharge resistor, which is positively correlated with the fan speed corresponding to the preset fan speed level.

[0129] In some embodiments, the fresh air system activates purification functions such as dust removal. In this case, its operating status information also includes purification level information. That is, the fresh air system operates with both fan speed and purification levels activated simultaneously. At this time, the battery discharges based on both the fan speed and purification level information. The first determining module 620 is also configured to determine a second discharge circuit based on a preset purification level in the purification level information. The second discharge circuit includes a second discharge resistor, which is positively correlated with the purification index of the preset purification level.

[0130] The selection of the purification level during the operation of a fresh air system can be determined based on the air quality index of the environment in which the system is located. For example, the worse the air quality, the higher the purification index corresponding to the preset purification level needs to be. For instance, taking PM2.5 as an example, a higher PM2.5 air quality index indicates worse air quality and a higher demand for air purification, requiring the activation of a high-power purification level, or even an ultra-high-power purification level. Correspondingly, the required discharge resistance value for the second discharge circuit also needs to be higher.

[0131] In some embodiments, the first determining module 620 is configured to,

[0132] Obtain the ambient air quality index;

[0133] Based on the ambient air quality index, determine the preset purification level for the purification level information;

[0134] The second discharge circuit is determined based on the preset purification level.

[0135] In some embodiments, when the fresh air device turns on the purification function, the first discharge circuit and the second discharge circuit discharge simultaneously. At this time, the determining unit 642 is configured to determine the remaining usage time of the filter based on the remaining voltage of the battery and the discharge parameters of the first discharge circuit and the discharge parameters of the second discharge circuit.

[0136] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

For example, device 700 may be a mobile phone, computer, digital broadcasting terminal, messaging device, game console, tablet device, medical device, fitness equipment, personal digital assistant, etc.

[0139] Processing component 702 typically controls the overall operation of device 700, such as operations associated with display, telephone calls, data communication, camera operation, and recording. Processing component 702 may include one or more processors 720 to execute instructions to complete all or part of the steps of the methods described above. Furthermore, processing component 702 may include one or more modules to facilitate interaction between processing component 702 and other components.
