Description

Technical Field

[0001] This invention relates to the field of intelligent control technology, specifically to control methods, devices, air purification equipment, and media for air purification equipment. Background Technology

[0002] As people's living standards improve, the usage rate of air purification devices is also increasing. With the further expansion of the air purification market, more and more types and functions of air purification products have emerged. Homes, as densely populated and enclosed spaces, have increasingly diverse functions. Current air purification equipment's automatic purification control is based on adjusting the purification level according to the concentration of pollutants in the air. While this can ensure purification effectiveness and avoid energy waste, it is not a sustainable solution.

[0003] However, since air purifiers have a timed purification function, in actual use, users will set the air purifier to run during a fixed purification period in order to avoid the noise and other impacts on their lives. In this scenario, if the control method of adjusting the air purifier speed solely based on the concentration of pollutants in the air, there is a risk that the concentration of air pollutants will still exceed the standard after the air purification time has arrived, which does not meet the user's actual air purification needs. Summary of the Invention

[0004] This invention provides a control method, device, air purification equipment, and medium for air purification equipment, in order to solve the problem that the concentration of air pollutants still exceeds the standard after the air purification time has been reached when the existing control method for air purification equipment operates during a fixed purification period.

[0005] In a first aspect, the present invention provides a method for controlling an air purification device, the method comprising:

[0006] When the air purifier enters the set purification operation period at the current time, the air purifier is controlled to start the purification mode and the total amount of pollutants in the current closed area where the air purifier is located is obtained. Calculate the first time required for the air purification device to purify the current total amount of pollutants at its highest operating setting; Based on the first duration, the target operating level of the air purifier is determined, and the air purifier is controlled to operate at the target operating level for a first preset operating duration, and the current total amount of pollutants is updated. The first preset operating duration is less than the total duration corresponding to the purification operation time period. Calculate the second time required for the air purifier to purify the current total amount of pollutants after the update at the target operating level; The target operating level is updated based on the second duration, and the process of controlling the air purifier to run at the target operating level for the first preset operating duration and updating the current total amount of pollutants continues until the end time of the purification operation period is reached, at which point the air purifier is controlled to turn off the purification mode.

[0007] This invention, upon entering a set purification operation period, obtains the total amount of pollutants in the current enclosed area and determines the target purification level by combining this with the first time required for the highest purification level. After the first preset operation period, the total pollutant amount is updated, and a second time is calculated, with the purification level being updated cyclically until the end time. This dynamic, phased adjustment of the purification level avoids the resource waste or insufficient purification caused by traditional fixed-level operation. By matching the total pollutant amount and purification level in real time, it ensures rapid purification at the appropriate level during periods of high pollution and allows for timely adjustments as pollutants decrease. This achieves optimal purification efficiency within the purification operation period, preventing the problem of excessive air pollutant concentrations after purification ends, meeting the actual air purification needs of users, and balancing purification effect with energy consumption optimization to avoid resource waste.

[0008] In one optional embodiment, the air purification device includes: a plurality of operating levels, wherein a higher operating level corresponds to a stronger purification capacity; and determining the target operating level of the air purification device based on the first duration includes: Determine whether the first duration is less than the first preset runtime; When the first duration is not less than the first preset running duration, the highest running gear is determined as the target running gear; When the first duration is less than the first preset running duration, the next lower running gear of the highest running gear is determined as the target running gear.

[0009] This invention determines the target setting based on the relationship between a first duration and a first preset running duration, clarifying the selection method between the highest setting and the next lower setting. When the first duration is not less than the first preset running duration, it indicates a large total amount of pollutants, and using the highest setting can quickly and efficiently treat high pollution levels. When the first duration is less than the first preset running duration, the total amount of pollutants is relatively small, and selecting the next lower setting can meet the purification requirements. It eliminates the need to operate at the highest setting throughout the entire process, reducing unnecessary energy consumption while ensuring purification efficiency. This allows the setting selection to better match the actual total amount of pollutants, improving the rationality of control.

[0010] In one optional implementation, updating the target operating gear based on the second duration includes: Determine whether the second duration is less than the second preset running duration. The second preset running duration is the preset duration corresponding to the current operating level of the air purifier. The higher the current operating level, the longer the corresponding preset duration. And the second preset running duration is less than the first preset running duration. When the first duration is not less than the second preset running duration, the current operating level of the air purifier is determined as the target operating level; When the first duration is less than the second preset duration, the next lower operating level of the air purifier is determined as the target operating level.

[0011] This invention updates the gear selection based on a second time interval and a second preset running time corresponding to the current gear level (the preset running time for higher gears is longer but shorter than the first preset running time), further refining the gear selection adjustment method. A longer second preset running time for higher gears ensures sufficient time for efficient purification in high-pollution scenarios; a shorter preset running time for lower gears facilitates timely detection of pollutant reduction and downshifting. This makes gear selection updates more targeted, avoiding over-running at high gears or insufficient purification at low gears. Therefore, based on the first stage of purification, the gear level is precisely adjusted according to the updated total amount of pollutants, further optimizing energy consumption and improving the accuracy and economy of the purification process.

[0012] In an optional implementation, before determining the next lower operating level of the air purifier as the target operating level, the method further includes: Determine whether the currently operating gear is the lowest operating gear; If the current operating gear is the lowest operating gear, the lowest operating gear is determined as the target operating gear; If the current operating level is not the lowest operating level, the step of determining the next lower operating level of the air purifier as the target operating level is executed.

[0013] Before adjusting to the next lower setting, this invention first determines whether the current setting is the lowest setting to avoid adjusting the setting beyond the equipment's operating range. If it is the lowest setting, it remains at that setting, ensuring basic purification is maintained even with extremely low pollutant levels, preventing purification interruptions. If it is not the lowest setting, it then downgrades, ensuring the continuity of setting adjustments. This feature prevents operational failures due to a lack of available settings and maintains purification with minimal energy consumption in low-pollution scenarios, ensuring the continuity and stability of the purification process while minimizing unnecessary energy consumption and improving the integrity of the control logic.

[0014] In an optional implementation, after updating the target operating gear based on the second duration, the method further includes: Determine whether the updated target operating gear is the lowest operating gear; When the updated target operating gear is the lowest operating gear, control the air purification device to operate at the lowest operating gear until the cut-off moment of the purification operation time period is reached, and control the air purification device to turn off the purification mode; When the updated target operating gear is not the lowest operating gear, return to the step of controlling the air purification device to operate at the target operating gear for the first preset operating duration and updating the current total amount of pollutants.

[0015] The present invention determines whether the target gear is the lowest gear after gear update. If so, it directly runs until the cut-off moment, without repeated calculation and adjustment, simplifies the control process in low-pollution scenarios, and reduces resource consumption in control links; if it does not reach the lowest gear, it continues to cycle and adjust to ensure precise regulation when the total amount of pollutants has not dropped to the ideal state. Thus, it takes into account both control efficiency and purification effect, avoids unnecessary calculations and adjustments at low gears to improve operating efficiency, and continuously dynamically regulates at non-low gears to ensure sufficient purification, achieving precise matching of the control process and purification requirements.

[0016] In an optional implementation manner, the method further includes: When the cut-off moment of the purification operation time period is reached, detect the pollutant concentration in the current enclosed area; When the pollutant concentration is higher than a preset pollutant concentration threshold, give a warning prompt.

[0017] The present invention detects the pollutant concentration at the cut-off moment of the purification operation time period and gives a warning when it is higher than the preset threshold. It can timely feedback the purification effect and prevent users from being in a polluted environment that does not meet the standards due to not understanding the purification result. The warning prompt allows users to quickly know the current air state, facilitating subsequent measures such as extending the purification time and checking the pollution source, ensuring user safety in use, making up for the defect that traditional purification equipment only completes operation without feedback on the effect, and improving the safety and user experience of equipment use.

[0018] In an optional implementation manner, the method further includes: Determine the release time period of the air purification device, and the release time period is before the purification operation time period; In response to the current moment entering the release time period, control the air purification device to turn on the release mode so as to accelerate the release of pollutants in the current enclosed area.

[0019] This invention accelerates pollutant release by setting a release period before the purification operation period begins and then activating the release mode. This solves the problem of pollutants being hidden or insufficiently released within enclosed areas, leading to only surface pollutant removal during the purification phase and subsequent secondary release. By accelerating release, hidden pollutants are fully exposed, allowing for more comprehensive and thorough removal in subsequent purification phases. This avoids the risk of incomplete purification, improves the overall purification effect, and ensures long-term stable compliance of air quality standards in enclosed areas.

[0020] In one alternative implementation, before determining the release time period of the air purifier, the method further includes: Obtain historical pollution data for the currently closed area; The historical pollution level of the currently closed area is determined based on the historical pollution data. When the historical pollution level is lower than the preset pollution level, the release mode of the air purifier is turned off; When the historical pollution level is not lower than the preset pollution level, the step of determining the release time period of the air purification device is performed.

[0021] This invention determines the pollution level based on historical pollution data. If the pollution level is below a preset threshold, the release mode is turned off; otherwise, a release time period is set. This avoids the indiscriminate activation of the release mode. Low historical pollution levels indicate a low pollutant release rate, eliminating the need for accelerated release and saving energy. When the pollution level is high, the release mode is activated to specifically address high-risk release scenarios. This makes the activation of the release mode more intelligent and targeted, ensuring that energy is not wasted in low-pollution scenarios while fully utilizing the release mode in high-pollution-risk scenarios, balancing energy consumption optimization and purification effect, and improving the rationality of system operation.

[0022] In a second aspect, the present invention provides an air purification equipment control device, the device comprising: The first processing module is used to control the air purifier to start the purification mode when the air purifier enters the purification operation period set by the air purifier at the current time, and to obtain the current total amount of pollutants in the current closed area where the air purifier is located. The second processing module is used to calculate the first time required for the air purification device to purify the current total amount of pollutants at its highest operating level. The third processing module is used to determine the target operating level of the air purifier based on the first duration, and control the air purifier to run at the target operating level for a first preset running time, and update the current total amount of pollutants, wherein the first preset running time is less than the total duration corresponding to the purification operation time period. The fourth processing module is used to calculate the second time required for the air purification device to purify the current total amount of pollutants after the update at the target operating level; The fifth processing module is used to update the target operating level based on the second duration, and return to the step of controlling the air purifier to run at the target operating level for the first preset running time, updating the current total amount of pollutants, until the end time of the purification operation period is reached, and then controlling the air purifier to turn off the purification mode.

[0023] Thirdly, the present invention provides an air purification device, comprising: A controller includes a memory and a processor, which are communicatively connected to each other. The memory stores computer instructions, and the processor executes the computer instructions to perform the method provided in the first aspect or any corresponding embodiment described above.

[0024] The air purification device provided by this invention has diverse functions such as dynamic gear adjustment, release mode control, and end-of-life warning. Compared with traditional single-function purification devices, it can flexibly adjust its operating status based on the total amount of pollutants and historical data, effectively removing pollutants while optimizing energy consumption. This enhances the device's intelligence and practical value, meeting users' needs for precise and efficient air purification.

[0025] In one alternative implementation, the air purification device is an air purifier.

[0026] The air purifier provided by this invention solves the problems of traditional air purifiers, such as single-level control, resource waste, and incomplete purification. It allows the air purifier to dynamically adjust its operating level and mode based on the total amount of pollutants in an enclosed area and historical pollution levels, effectively removing pollutants such as formaldehyde. This ensures purification effectiveness while avoiding unnecessary energy consumption, providing users with a more comfortable and safer indoor air environment, and significantly improving the user experience and market competitiveness of air purifiers.

[0027] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to perform the method provided in the first aspect or any corresponding embodiment thereof. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Because air purifiers have a timed purification function, in actual use, users will set the air purifier to run during a fixed purification period in order to avoid the noise and other impacts on their lives. In this scenario, if the control method of adjusting the air purifier speed is based solely on the concentration of pollutants in the air, there is a risk that the concentration of air pollutants will still exceed the standard after the air purification time has been reached, which does not meet the user's actual air purification needs.

[0034] Based on the above problems, this embodiment monitors environmental conditions and adjusts the air purifier's settings to create optimal purification conditions, reduce resource waste, and achieve the best purification effect.

[0035] Figure 1 This is a structural diagram of an air purification device, such as... Figure 1 As shown, the air purification device includes a controller 101 for executing an air purification device control method to control the operation of the air purification device. Details of the process by which the controller 101 executes the air purification device control method are described in the relevant description of the method embodiments below, and will not be repeated here.

[0036] The air purification device provided in this embodiment has diverse functions such as dynamic speed adjustment, release mode control, and end-of-life warning. Compared with traditional single-function purification devices, it can flexibly adjust its operating status based on the total amount of pollutants and historical data, effectively removing pollutants while optimizing energy consumption. This enhances the device's intelligence and practical value, meeting users' needs for precise and efficient air purification.

[0037] For example, the air purifier device described above is an air purifier. In addition, it can also be other devices with air purification functions, such as air conditioners, etc. The present invention is not limited thereto.

[0038] The air purifier provided in this embodiment solves the problems of traditional air purifiers, such as single-level control, resource waste, and incomplete purification. It allows the air purifier to dynamically adjust its operating level and mode based on the total amount of pollutants in an enclosed area and historical pollution levels, effectively removing pollutants such as formaldehyde. This ensures purification effectiveness while avoiding unnecessary energy consumption, providing users with a more comfortable and safer indoor air environment, and significantly improving the user experience and market competitiveness of air purifiers.

[0039] According to an embodiment of the present invention, an embodiment of an air purification device control method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0040] This embodiment provides a control method for an air purification device, which can be used in the controller of the aforementioned air purification device, such as a microcontroller or MCU. Figure 2 This is a flowchart of an air purification device control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: In response to the current time entering the purification operation period set by the air purification device, control the air purification device to start the purification mode and obtain the current total amount of pollutants in the current closed area where the air purification device is located.

[0041] The purification mode, also known as the removal mode, is the working mode of the air purification device to achieve the air purification function. In application scenarios such as homes or companies, the currently enclosed area is the room where the air purification device is located. In practical applications, the currently enclosed area can also be the sealed space where the air purifier is located. The pollutants can be set according to the actual purification function selected by the air purifier, such as formaldehyde, PM2.5, etc. In this embodiment of the invention, formaldehyde is used as an example. This is just an example, and the invention is not limited thereto.

[0042] For example, assuming the purification operation period is from 17:00 to 18:00 daily, corresponding to a total duration of one hour, when the air purifier's time detection module detects that the current time has reached 17:00 (i.e., entering the set purification operation period), the device automatically responds and starts the purification mode. Simultaneously, the formaldehyde concentration sensor is activated to detect the current formaldehyde concentration c0 in the living room in real time. The formaldehyde concentration sensor transmits the detected concentration data to the controller. The controller calculates the current total pollutant M based on the preset room volume V using the formula M=c0×V (where M is the total mass of formaldehyde, in mg; c0 is the current formaldehyde concentration, in mg / m³; and V is the room volume, in m³).

[0043] Step S202: Calculate the first time required for the air purification equipment to purify the current total amount of pollutants at its highest operating level.

[0044] Specifically, the air purification device includes several operating levels. The higher the operating level, the stronger the purification capacity. In this embodiment of the invention, the operating levels are described as including the highest operating level, the middle operating level, and the lowest operating level. In practical applications, two or more operating levels can be set according to the actual design requirements of the air purification device. This invention is not limited to this.

[0045] For example, the air purifier has three fan speed settings corresponding to three formaldehyde purification rates, v1, v2, and v3. The controller calls the pre-stored highest operating speed, v3, which corresponds to a formaldehyde purification rate of 0.42 mg / min. The first time required for the air purifier to purify the current total amount of pollutants M at the highest speed v3 is calculated using the formula: First Time = M / v3 (in minutes, where v3 is the highest purification rate in mg / min). The core of this calculation process is to determine the theoretical time required for initial purification by matching the total amount of pollutants with the purification capacity of the highest speed, thus providing a basis for selecting subsequent speed settings.

[0046] Step S203: Determine the target operating level of the air purifier based on the first duration, and control the air purifier to run at the target operating level for the first preset duration, and update the current total amount of pollutants.

[0047] The first preset running time is less than the total duration corresponding to the purification operation period. For example, the first preset running time is 20 minutes.

[0048] Specifically, based on the first duration calculated in step S202, the controller determines the target operating level: if the first duration is long, it indicates that the total amount of pollutants is large, requiring rapid purification at the highest level v3; if the first duration is short, it indicates that the total amount of pollutants is relatively small, and the next lower level, i.e., the intermediate level v2, can be selected to balance purification efficiency and energy consumption. After determining the target level, the controller controls the air purifier to run continuously at that level for a first preset running time (20 minutes). After the operation ends, the formaldehyde concentration sensor detects the current formaldehyde concentration c0' again and updates the current total pollutant M' using the formula M'=c0'×V.

[0049] Step S204: Calculate the second time required for the air purification equipment to purify the current total amount of pollutants after the update at the target operating level.

[0050] Specifically, the controller calls the purification rate corresponding to the current operating level (taking V3 as an example) and calculates the second time required for the total amount of pollutants M' after purification update using the formula t2=M' / v (where v is the purification rate of the current target level). The purpose of this step is to reassess the purification requirements of the current level by updating the total amount of pollutants in real time, providing data support for subsequent level adjustments.

[0051] Step S205: Update the target operating level based on the second duration, and return to the step of controlling the air purifier to run at the target operating level for the first preset running time, updating the current total amount of pollutants, until the end time of the purification operation period is reached, and control the air purifier to turn off the purification mode.

[0052] Specifically, based on the second duration calculated in step S204, and combined with the preset gear adjustment rules (i.e., a longer second duration maintains the current gear, a shorter second duration lowers the gear), the controller updates the target operating gear. After the update, it returns to step S203 and repeats the above steps until the formaldehyde concentration sensor detects that the current time has reached the end time of the purification operation period (18:00), at which point the controller controls the air purifier to turn off the purification mode.

[0053] This embodiment, after entering the set purification operation period, obtains the total amount of pollutants in the current enclosed area and determines the target purification level by combining it with the first time required for the highest purification level. After the first preset operation time, the total amount of pollutants is updated and a second time is calculated, and the purification level is updated cyclically until the end time. This dynamic, phased adjustment of the purification level avoids the resource waste or insufficient purification caused by traditional fixed-level operation. By matching the total amount of pollutants and the purification level in real time, it ensures rapid purification at an appropriate level during periods of high pollution and timely adjustments after pollutant levels decrease. This achieves optimal purification efficiency within the purification operation period, preventing the problem of excessive air pollutant concentrations after purification ends, meeting the user's actual air purification needs, and balancing purification effect with energy consumption optimization to avoid resource waste.

[0054] This embodiment provides a control method for an air purification device, which can be used in the controller of the aforementioned air purification device, such as a microcontroller or MCU. Figure 3 This is a flowchart of an air purification device control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: Determine the release time period of the air purification equipment.

[0055] The release time period is set before the purification operation period. The core principle of setting the release time period is "not affecting the user's life and ensuring the accelerated release of pollutants is completed before the purification operation period." Considering the work schedules of working professionals and the logic of the instruction manual, the release time period is prioritized based on weekdays and non-working days: If the current date is a weekday (determined by the device's built-in calendar module and weekday setting function, with Monday to Friday as the default), the release time period is set from when the user leaves home until they return, i.e., 9:00-17:00. This time period is before the purification operation period (17:00-18:00), ensuring that the accelerated formaldehyde release is concentratedly removed during the purification period. If the current date is a non-working day, the release time period can be set by the user through a mobile app or the device's control panel (e.g., if the user is out all day, it can be set to 8:00-16:00), flexibly adapting to non-working day usage scenarios.

[0056] Furthermore, before performing step S301 above, the air purification device control method provided in this embodiment of the invention further includes the following steps: Step s1: Obtain historical pollution data for the currently closed area.

[0057] For example, the air purifier's historical data monitoring module automatically stores historical formaldehyde pollution data for the currently enclosed area (master bedroom), with a default data storage period of 30 days (which can be customized by the user). This module uses the device's built-in formaldehyde concentration sensor to collect formaldehyde concentration data once per hour, generating a "time-concentration" historical curve and recording the date, detection time, and concentration value for each curve. The controller retrieves all valid detection data and corresponding historical curves from the past 30 days by accessing the stored data in the historical data monitoring module, thus obtaining historical pollution data and providing a basis for subsequent pollution level assessment.

[0058] Step s2: Determine the historical pollution level of the currently closed area based on historical pollution data.

[0059] Specifically, the controller performs statistical analysis on the acquired historical pollution data. For example, it divides the formaldehyde concentration curve display range vertically into three equal parts, corresponding to three pollution levels: "Excellent (green, ≤0.08mg / m³), Good (yellow, 0.08-0.10mg / m³)," and "Poor (red, >0.10mg / m³)." The controller first calculates the percentage of time in the green area in the daily historical curve, then calculates the number of days with a 100% percentage of green area time within 30 days. Finally, it determines the proportion of this number to the total number of statistical days (30 days) to determine the historical pollution level. If this proportion is ≥95%, the historical pollution level is determined to be "lower than the preset pollution level"; if this proportion is <95%, the historical pollution level is determined to be "not lower than the preset pollution level."

[0060] Step s3: When the historical pollution level is lower than the preset pollution level, turn off the release mode of the air purifier.

[0061] Specifically, if the determination result of step s2 is that the historical pollution level is lower than the preset pollution level, it means that the formaldehyde release rate of the current closed area has been at a low level for a long time. There is no need to accelerate the release of pollutants through the release mode. The controller will directly turn off the release mode of the air purifier. The purification mode can be turned on only during the purification operation period to avoid energy waste caused by the ineffective operation of the release mode.

[0062] Step s4: If the historical pollution level is not lower than the preset pollution level, execute step S301.

[0063] Specifically, if the determination result of step s2 is that the historical pollution level is not lower than the preset pollution level, it means that there is still a situation of slow or intermittent release of formaldehyde in the current closed area. It is necessary to accelerate the release of hidden pollutants through the release mode to ensure that the subsequent purification mode can completely remove the pollutants. At this time, the controller triggers step S301 and enters the release time period determination process.

[0064] This embodiment determines the pollution level based on historical pollution data. If the pollution level is below a preset threshold, the release mode is turned off; otherwise, a release time period is set. This avoids the indiscriminate activation of the release mode. Low historical pollution levels indicate a low pollutant release rate, eliminating the need for accelerated release and saving energy. When the pollution level is high, the release mode is activated to specifically address high-risk release scenarios. This makes the activation of the release mode more intelligent and targeted, ensuring that energy is not wasted in low-pollution scenarios while fully utilizing the release mode in high-pollution-risk scenarios, balancing energy consumption optimization and purification effect, and improving the rationality of system operation.

[0065] Step S302: In response to the current time entering the release period, control the air purification equipment to turn on the release mode so that the pollutants in the current closed area are released more quickly.

[0066] Specifically, when the air purifier's time detection module detects that the current time has entered the set release period (e.g., 9:00 AM on a weekday), the controller immediately responds and controls the device to activate the release mode, starting the built-in heating and humidification modules: the heating module maintains the room temperature at 26-28℃ (this temperature range can significantly accelerate the release of formaldehyde from furniture, wood panels, and other carriers), and the humidification module maintains the room relative humidity at 55-60% (moderate humidification can further increase the formaldehyde release rate). Simultaneously, purification-related components are shut down, ensuring that the energy of the release mode is concentrated on accelerating the release of pollutants. During the release period, the formaldehyde concentration sensor continues to collect data every 30 minutes, but this is only for recording and does not trigger purification actions until the release period ends (e.g., 5:00 PM), at which point the release mode automatically shuts off, and the device enters a standby purification state.

[0067] This embodiment accelerates pollutant release by setting a release period before the purification operation period and then activating the release mode. This solves the problem of pollutants being hidden or insufficiently released within enclosed areas, leading to only surface pollutant removal during the purification phase and subsequent secondary release. By accelerating release, hidden pollutants are fully exposed, allowing for more comprehensive and thorough removal in subsequent purification phases. This avoids the risk of incomplete purification, improves the overall purification effect, and ensures long-term stable compliance of air quality standards in enclosed areas.

[0068] Step S303: In response to entering the set purification operation period of the air purifier at the current time, control the air purifier to start the purification mode and obtain the current total amount of pollutants in the currently enclosed area where the air purifier is located. See details below. Figure 2 The relevant descriptions of step S201 shown will not be repeated here.

[0069] Step S304: Calculate the first time required for the air purifier to purify the current total amount of pollutants at its highest operating level. See details below. Figure 2 The relevant descriptions of step S202 shown will not be repeated here.

[0070] Step S305: Determine the target operating level of the air purifier based on the first duration, and control the air purifier to run at the target operating level for the first preset duration, and update the current total amount of pollutants.

[0071] The first preset running time is less than the total duration corresponding to the purification running time period.

[0072] Specifically, the air purification device includes several operating levels, with higher operating levels corresponding to stronger purification capabilities. The step S305 above, which determines the target operating level of the air purification device based on the first duration, includes: Step a1: Determine whether the first duration is less than the first preset running duration.

[0073] Step a2: When the first duration is not less than the first preset running duration, the highest running gear is determined as the target running gear.

[0074] Step a3: When the first duration is less than the first preset running duration, the next lower running gear after the highest running gear is determined as the target running gear.

[0075] For example, the system determines whether the first duration is less than the first preset running time (20 minutes). If the determination result is that the first duration is greater than or equal to the first preset running time (20 minutes), it indicates that the total amount of formaldehyde in the current enclosed area is large, and it is difficult to achieve efficient purification within a limited time by relying solely on the low or medium speed settings. Therefore, the system needs to activate the maximum speed setting (v3) with the strongest purification capacity to treat high-concentration pollutants at the fastest purification rate, avoiding pollutant residue due to untimely purification. Based on this determination result, the controller automatically determines the maximum speed setting (v3) as the target operating speed and generates corresponding operating instructions to ensure that the equipment is put into the initial purification stage with the strongest purification intensity, laying an efficient foundation for subsequent segmented control.

[0076] Conversely, if the judgment result is that the first duration is less than the first preset running duration (20 minutes), it indicates that the total amount of formaldehyde in the current enclosed area is relatively moderate, and purification can be completed within the preset time without relying on the super-strong purification capacity of the highest setting. If the controller is still running at the highest setting at this time, it will waste energy and may generate excessive operating noise that will affect the environment. Therefore, the controller follows the principle of "matching on demand" and determines the next lower setting (i.e., medium setting v2) as the target operating setting, so as to achieve an optimal balance between energy consumption and noise while ensuring that the purification efficiency meets the requirements.

[0077] This embodiment determines the target setting based on the relationship between a first duration and a first preset running duration, clarifying the selection method between the highest setting and the next lower setting. When the first duration is not less than the first preset running duration, it indicates a large total amount of pollutants, and using the highest setting can quickly and efficiently treat high pollution levels. When the first duration is less than the first preset running duration, the total amount of pollutants is relatively small, and selecting the next lower setting can meet the purification requirements. It is not necessary to operate at the highest setting throughout the entire process, ensuring purification efficiency while reducing unnecessary energy consumption. This allows the setting selection to better match the actual total amount of pollutants, improving the rationality of control.

[0078] Step S306: Calculate the second time required for the air purification equipment to purify the current total amount of pollutants after the update at the target operating level. See details below. Figure 2 The relevant description of step S204 shown will not be repeated here.

[0079] Step S307: Update the target operating level based on the second duration, and return to the step of controlling the air purifier to run at the target operating level for the first preset running time, updating the current total amount of pollutants, until the end time of the purification operation period is reached, and control the air purifier to turn off the purification mode.

[0080] Specifically, the step S307 above, which updates the target operating gear based on the second duration, includes: Step b1: Determine whether the second duration is less than the second preset running duration.

[0081] The second preset running time is the preset duration corresponding to the current operating level of the air purifier. The higher the current operating level, the longer the preset duration, and the second preset running time is less than the first preset running time. For example, the preset duration corresponding to the maximum level v3 is 15 minutes, the preset duration corresponding to the intermediate level v2 is 10 minutes, and the preset duration corresponding to the minimum level v1 is 5 minutes.

[0082] Step b2: When the first duration is not less than the second preset running duration, the current operating level of the air purifier is determined as the target operating level.

[0083] Step b3: When the first duration is less than the second preset duration, the next lower operating level of the air purifier is determined as the target operating level.

[0084] For example, if the judgment result is that the second duration is greater than or equal to the second preset running duration corresponding to the current operating level, it indicates that the total amount of pollutants after the update is still at a high level, and the purification rate of the current level can still match the purification needs of the remaining pollutants. If the level is downgraded abruptly, it may lead to untimely subsequent purification and pollutant residue. Therefore, based on this judgment result, the controller maintains the current operating level unchanged, directly determines it as the updated target operating level, and generates a continuous operation command to control the air purifier to continue running at this level for the first preset running duration (20 minutes), ensuring the continuity of high purification intensity and rapidly reducing the total amount of pollutants. At this time, if the current level is v3, then v3 will continue to be determined as the target operating level; if the current level is v2, then v2 will continue to be determined as the target operating level.

[0085] Conversely, if the judgment result is that the second duration is less than the second preset duration corresponding to the current operating level, it indicates that the total amount of pollutants after the update has been significantly reduced, and the purification capacity of the current level has exceeded the actual needs. If the current level is maintained, it will not only waste electricity but may also generate unnecessary noise due to high fan speed, affecting the user experience of subsequent users entering the room. Therefore, the controller follows the core idea of ​​"feedback adjustment and downshifting as needed," determining the next lower level of the current operating level as the target operating level after the update. This achieves dual optimization of energy consumption and noise while ensuring that the remaining pollutants are fully purified. At this time, if the current level is v3, then v2 is determined as the target operating level; if the current level is v2, then v1 is determined as the target operating level.

[0086] This embodiment updates the gear selection based on the second duration and the second preset running duration corresponding to the current gear level (the preset running duration for higher gears is longer but shorter than the first preset running duration), further refining the gear adjustment method. The longer second preset running duration for higher gears ensures sufficient time for efficient purification in high-pollution scenarios; the shorter preset running duration for lower gears facilitates timely detection of pollutant reduction and downshifting. This makes gear updates more targeted, avoiding over-operation at high gears or insufficient purification at low gears. Therefore, based on the first stage of purification, the gear level is precisely adjusted according to the updated total pollutant amount, further optimizing energy consumption and improving the accuracy and economy of the purification process.

[0087] Furthermore, before performing step b3 above, the air purification device control method provided in this embodiment of the invention further includes: Step c1: Determine whether the current operating gear is the lowest operating gear.

[0088] Step c2: If the current operating gear is the lowest operating gear, determine the lowest operating gear as the target operating gear.

[0089] Specifically, if the current operating setting is the lowest setting, the system will not downgrade but will maintain the lowest setting to ensure the basic purification function of the air purifier.

[0090] Step c3: If the current operating gear is not the lowest operating gear, proceed to step b3.

[0091] Before adjusting to the next lower setting, this embodiment first determines whether the current setting is the lowest setting to avoid adjusting the setting beyond the equipment's operating range. If it is the lowest setting, it remains at that setting, ensuring basic purification is maintained even with extremely low pollutant levels, preventing purification interruptions. If it is not the lowest setting, it then downgrades to ensure the continuity of setting adjustments. This feature prevents operational failures due to the lack of available settings and maintains purification with minimal energy consumption in low-pollution scenarios, ensuring the continuity and stability of the purification process while minimizing unnecessary energy consumption and improving the integrity of the control logic.

[0092] In some optional implementations, after updating the target operating gear based on the second duration, step S207 above further includes the following steps: Step d1: Determine whether the updated target gear is the lowest gear.

[0093] Step d2: When the updated target operating level is the lowest operating level, control the air purifier to operate at the lowest operating level until the end of the purification operation period, then control the air purifier to turn off the purification mode.

[0094] Step d3: If the updated target operating level is not the lowest operating level, return to step S305 to control the air purification equipment to run at the target operating level for the first preset running time and update the current total amount of pollutants.

[0095] For example, if the judgment result is "the updated target operating level is the lowest operating level (minimum level v1)", it means that the total formaldehyde content in the current enclosed area has been reduced to a low level, the purification rate of the lowest level is sufficient to meet the remaining purification needs, and the v1 level has the advantages of low energy consumption and low noise, which is suitable for scenarios where working families may enter the room to rest after get off work (such as a children's room for children). At this time, the controller generates a continuous operation command to control the air purifier to maintain operation at v1 level, without performing subsequent level adjustments or loop calculations, until the device's time detection module detects that the current time has reached the end time of the purification operation period (18:00). The controller immediately sends a shutdown command to stop the air purifier's purification mode and complete the entire purification process.

[0096] Conversely, if the judgment result is that "the updated target operating gear is not the lowest operating gear", it means that although the current total amount of pollutants has decreased, it still has not reached the level where only the lowest gear purification is required, and there is still room for gear optimization (for example, after updating from gear v3 to gear v2, the remaining pollutants may still be able to further save energy consumption by downshifting to gear v1). At this time, the controller does not terminate the loop process, but returns to the above step of "controlling the air purification device to operate at the target operating gear for the first preset operating duration (20 min) and updating the current total amount of pollutants", and continues to execute the closed-loop operation of "operation - detection - calculation of duration - judgment of downshifting" until the subsequent gear is updated to the lowest gear or the cut-off moment of the purification operation time period is reached.

[0097] In this embodiment, it is judged whether the target gear is the lowest gear after the gear is updated. If so, it directly runs until the cut-off moment without repeated calculation and adjustment, simplifying the control process in the low-pollution scenario and reducing the resource consumption of the control link; if it does not reach the lowest gear, it continues to loop and adjust to ensure accurate regulation when the total amount of pollutants has not dropped to the ideal state. Thus, it takes into account both control efficiency and purification effect, avoiding unnecessary calculations and adjustments at low gears to improve the operation efficiency, and continuously dynamically regulating at non-low gears to ensure sufficient purification, achieving an accurate match between the control process and the purification requirements.

[0098] Step S308, when the cut-off moment of the purification operation time period is reached, detect the pollutant concentration in the current enclosed area.

[0099] Specifically, the time detection module of the air purifier monitors the current time in real time. When it detects that the time precisely reaches 18:00, it immediately sends a "cut-off moment trigger signal" to the controller. After the controller responds to this signal, it starts the formaldehyde concentration sensor to perform a high-precision concentration detection (detection accuracy ≤ 0.01 mg / m³ to ensure data accuracy), and focuses on collecting the real-time formaldehyde concentration data in the current enclosed area (living room), rather than the total amount of pollutants. Its core purpose is to directly judge whether the final air quality meets the standard, providing an intuitive and accurate judgment basis for the subsequent warning logic. After the detection is completed, the sensor transmits the real-time concentration data to the controller. The controller stores and records the data (for the user to view through the historical curve later), and at the same time triggers the next threshold comparison process.

[0100] Step S309, when the pollutant concentration is higher than the preset pollutant concentration threshold, give a warning prompt.

[0101] Specifically, after receiving the real-time pollutant concentration data in step S308, the controller immediately calls the pre-stored preset pollutant concentration threshold (e.g., 0.08 mg / m³) and directly compares the real-time concentration with the threshold. If the comparison result is "real-time pollutant concentration is higher than the preset threshold," it means that after a complete purification operation period, the air quality in the current enclosed area still has not reached the safety standard, and the user needs to be promptly reminded to take subsequent measures. If the comparison result is "real-time pollutant concentration is lower than or equal to the preset threshold," it means that the purification effect meets the standard, and there is no need to trigger an alarm. The controller only records the "purification meets the standard" status and then controls the air purifier to turn off the purification mode, and the purification process ends normally.

[0102] This embodiment detects pollutant concentration at the end of the purification operation period and issues an alert when the concentration exceeds a preset threshold. It provides timely feedback on the purification effect, preventing users from being in a substandard polluted environment due to a lack of awareness of the results. The alert allows users to quickly understand the current air quality, facilitating subsequent measures such as extending the purification time or checking for pollution sources, ensuring user safety. This overcomes the shortcomings of traditional purification equipment that only completes operation without providing feedback, thus improving equipment safety and user experience.

[0103] The following will provide a detailed explanation of the specific working process of the air purification equipment control scheme provided in the embodiments of the present invention, using specific application examples.

[0104] When air purifiers are used in home environments, the optimal purification effect is achieved by adjusting the air purification level. The specific process includes: The controller's personnel monitoring module detects whether anyone is home in real time. When someone is home, the homeowner can choose to disable functions that promote formaldehyde release, such as heating and humidification. The system monitors formaldehyde levels in the room; if the concentration is below the safe threshold, it operates in sleep mode; if the concentration is above the safe threshold, it operates in high-power removal mode, checking the formaldehyde concentration every 5 minutes. If the concentration exceeds the safe threshold, the cycle repeats; otherwise, it operates in sleep mode. When no one is home, the function that promotes formaldehyde release is activated, i.e., the release mode.

[0105] The controller's weekday monitoring module detects the current date in real time and determines whether it is a weekday. The purifier's operation differs between weekdays and non-weekdays. When the current date is a weekday, the environmental release time is set (e.g., 9:00-17:00), the release mode is turned off, and the removal mode is turned on (e.g., 17:00-18:00). With removal mode on, the room volume is set to V, the safety threshold to c, and the air purifier's three fan speed settings correspond to three formaldehyde purification rates v1, v2, and v3, respectively. Based on the room's formaldehyde concentration c0, the total formaldehyde concentration M is calculated as M = c0. V. Calculate the time t1 required for the maximum setting (v3). When t1 ≥ 20 min, activate the maximum setting (v3) and run continuously for 20 min to detect the formaldehyde concentration in the room. Calculate the time t2 required for the maximum setting. If t2 ≤ 15 min, switch to setting v2 and run for 20 min. Detect the formaldehyde concentration in the room again. Calculate the time t3 required for the second setting. If t3 ≤ 10 min, switch to setting v1 and run for 20 min. Detect the formaldehyde concentration in the room again. When the concentration reaches the safe threshold, continue running at the lowest setting and remotely alert the user that the safe threshold has been reached. When the remaining time is 0 and the formaldehyde concentration in the room has not yet reached the safe threshold, a remote alert is issued. If the current date is a non-working day, the homeowner can determine the operating mode themselves. For example, if they are going out all day, they can activate the release + removal mode.

[0106] In addition, historical data monitoring modules of the air purifier can be used to view historical curves. The interface displays the maximum and minimum values ​​of the time-concentration curve. The display range is vertically divided into three equal parts, corresponding to excellent, good, and poor formaldehyde quality, respectively. The curve color corresponds to the formaldehyde quality level when it falls within different ranges: green, yellow, and red, respectively. When the formaldehyde concentration of the curve is in the green area for 95% of the continuous operation, it indicates a low formaldehyde release rate in the room, and the release mode can be directly turned off. For example, the specific working process of the air purification equipment is as follows... Figure 4 As shown.
