Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an air purifier, a control method and device for the air purifier, and a computer device. Background Technology

[0002] In recent years, with the booming development of the pet economy, the number of pet households has grown rapidly, and indoor air pollution has become an increasingly prominent problem, which in turn has driven the rapid expansion of the pet furniture market. The pet hair, dander, odors from excrement, and microorganisms generated by pets during their daily activities pose a dual threat to the living environment and human health.

[0003] However, while the pet air purifier market is expanding rapidly, the disconnect between product development and real user needs is becoming increasingly apparent. On the one hand, in order to quickly seize market share, companies often compress development cycles, resulting in a large number of products with highly homogenized functions and a lack of in-depth research on pet behavior patterns (such as activity patterns) and users' implicit needs (such as the comfort and safety of living with pets). On the other hand, existing products mostly focus on single-function development, failing to effectively integrate relevant knowledge such as animal behavior and lacking systematic integration with cutting-edge technologies such as artificial intelligence and environmental sensing.

[0004] Existing technologies have proposed pet air purifiers capable of precisely purifying pet activity spaces. These purifiers use data such as target image information and ammonia concentration to assess and track pet movement. However, the image acquisition devices used in these solutions may pose security risks, such as user privacy breaches, and require further optimization and improvement. Summary of the Invention

[0005] In view of this, the present invention provides an air purifier, an air purifier control method, an apparatus, and a computer device to solve the problem of privacy leakage risks when current air purifiers are used to specifically purify pet activity spaces.

[0006] In a first aspect, the present invention provides a control method for an air purifier, comprising the following steps: obtaining the current operating mode of the air purifier; when the current operating mode of the air purifier is a guardian mode, obtaining the location information of a pet, wherein the location information is obtained using ultra-wideband indoor positioning technology based on a positioning tag carried by the pet; obtaining a map, wherein the map is constructed using ultra-wideband indoor positioning technology and a lidar sensor carried in the air purifier; determining whether a preset guardian purification task trigger condition has been met based on the location information and the map; and executing the guardian purification task when the guardian purification task trigger condition is met.

[0007] This invention integrates ultra-wideband indoor positioning technology with lidar sensors to construct a map, and combines this with a pet's location tag to achieve precise location tracking. While protecting user privacy, it enhances the targeted purification capabilities of air purifiers for pet-friendly spaces. Furthermore, this method intelligently determines whether preset purification conditions are met, automatically executing corresponding purification tasks. This not only improves air purification efficiency but also enhances the intelligent level of air quality management in human-pet cohabitation environments, demonstrating promising application prospects and market potential.

[0008] In one optional implementation, the guardian purification task includes a pet area purification task and a pet follow-purification task. Determining whether the preset guardian purification task triggering conditions are met based on location information and the map includes: determining whether the pet's dwell time in a preset pet activity area reaches a preset first duration threshold; when the pet's dwell time in the pet activity area reaches the first duration threshold, the triggering condition for the pet area purification task is determined to be met; and determining whether the pet has returned from outdoors or whether the duration of the pet's vigorous exercise reaches a preset second duration threshold; when the pet has returned from outdoors or the duration of the pet's vigorous exercise reaches the second duration threshold, the triggering condition for the pet follow-purification task is determined to be met.

[0009] This invention distinguishes between air purifier tasks in pet-controlled areas and those that follow pets. It intelligently determines the triggering conditions for purification tasks based on multi-dimensional behavioral characteristics such as the duration of a pet's stay in the activity area, its return from outside, and its state of vigorous exercise. This not only improves the accuracy of the air purifier's response to pet behavior but also enhances the targeting and energy-saving effect of the purification process, further optimizing the air quality management level in human-pet cohabitation environments.

[0010] In one optional implementation, when the triggering condition for the guardian purification task is met, the guardian purification task includes: when the triggering condition for the pet area purification task is met, controlling the air purifier to enter the pet activity area according to the map and performing a first purification treatment on the pet activity area until a preset purification effect is achieved; when the triggering condition for the pet follow purification task is met, controlling the air purifier to perform a second purification treatment according to the pet's movement path according to the map until a preset purification effect is achieved.

[0011] This invention dynamically executes area purification and follow-up purification tasks based on pet behavior characteristics. This not only enables the air purifier to adaptively track and purify pet activity trajectories, improving purification efficiency and targeting, but also effectively avoids redundant coverage and reduces energy consumption by combining map navigation technology. This further enhances the intelligence and precision of air quality management in human-pet cohabitation scenarios.

[0012] In one optional implementation, performing a first purification treatment on the pet activity area includes: determining a purification type for the first purification treatment based on the pet activity area; acquiring the pet's personalized characteristics and determining first purification parameters for the purification type based on the personalized characteristics, wherein the first purification parameters include at least one of the following: purification wind speed and purification duration; performing the first purification treatment on the pet activity area using the first purification parameters; and / or; controlling an air purifier to perform a second purification treatment according to the pet's movement path includes: acquiring the pet's personalized characteristics and determining second purification parameters for the second purification treatment based on the personalized characteristics; wherein the second purification parameters include at least one of the following: purification wind speed, following distance, following speed, and purification duration.

[0013] This invention combines the individual characteristics of pets to dynamically generate customized purification solutions for different purification tasks, and supports users in editing purification parameters and providing feedback on effects, thus realizing the intelligent and personalized operation of air purifiers. It not only improves the accuracy and adaptability of purification in pet activity spaces, but also continuously optimizes purification strategies through user participation and feedback mechanisms, further enhancing the comfort and efficiency of air purification in human-pet cohabitation environments.

[0014] In one optional implementation, the air purifier control method further includes the following steps: determining whether there are other protective purification tasks in the process of execution; when there are other protective purification tasks in the process of execution, obtaining a preset priority sorting rule; determining whether the priority of the protective purification task is higher than that of other protective purification tasks in the process of execution according to the priority sorting rule; and executing the protective purification task when the priority of the protective purification task is higher than that of other protective purification tasks in the process of execution.

[0015] This invention introduces a priority judgment and scheduling mechanism for air purification tasks, ensuring that the air purifier can dynamically adjust the task execution order according to preset rules when multiple tasks are running in parallel. This effectively avoids task conflicts and improves the coordination and execution efficiency of the system. Simultaneously, this mechanism can flexibly configure task priorities according to different scenarios, enhancing the air purifier's intelligent response capabilities and adaptability in complex environments where humans and pets coexist.

[0016] In one optional implementation, the air purifier control method further includes the following steps: when the current operating mode of the air purifier is normal purification mode, obtaining user instructions; determining the purification range of the air purifier according to the user instructions; and controlling the air purifier to perform normal purification tasks within the purification range according to the map.

[0017] This invention introduces a user-defined purification range function in the normal purification mode and combines map information to achieve precise navigation and area purification of the air purifier, improving the device's flexibility and intelligence in different usage scenarios. Through the linkage control of user commands and map data, it not only enhances the air purifier's adaptability to complex home environments but also provides users with a more convenient and efficient human-computer interaction experience.

[0018] In one optional implementation, after performing the guardian purification task, the process further includes: determining whether the pet has gone out based on the pet's location information and a map; when the pet has gone out, determining whether the pet has permission to go out; when the pet does not have permission to go out, issuing a notification message; and / or, determining whether the pet has entered a preset pet restricted area based on the pet's location information and a map, wherein the pet restricted area is determined based on the pet's activity permissions; when the pet enters the pet restricted area, pausing the guardian purification task or the normal purification task, controlling the air purifier to enter the pet restricted area, and performing a preset guidance task to guide the pet out of the pet restricted area; and continuing to perform the guardian purification task or the normal purification task after the pet leaves the pet restricted area.

[0019] This invention combines pet location information with a map to achieve intelligent monitoring of pets' outdoor status and activity range, expanding pet behavior management functions beyond air purifiers. When a pet goes out without authorization or enters a pet-restricted area, the system can promptly issue a prompt or proactively perform guidance tasks, effectively improving the safety and intelligent management level in human-pet cohabitation environments, while also enhancing the collaborative service capabilities of air purifiers in multiple scenarios.

[0020] In one optional implementation, the air purifier control method further includes the following steps: acquiring the air purifier's power information; determining whether the air purifier needs charging based on the power information; when the air purifier needs charging, pausing the execution of the protective purification task or the normal purification task, and controlling the air purifier to charge; and resuming the execution of the protective purification task or the normal purification task after the air purifier has finished charging.

[0021] This invention monitors the air purifier's battery status in real time and intelligently plans charging behavior, ensuring that the device will not be interrupted due to insufficient power during purification tasks, effectively improving the system's battery life and operational stability. Simultaneously, this function further enhances the air purifier's autonomous operation capability without human intervention, providing reliable support for continuously ensuring air quality in environments where humans and pets coexist.

[0022] Secondly, the present invention also provides a control device for an air purifier, the device comprising an operating mode acquisition module, a pet location acquisition module, a judgment module, and a purification task execution module; wherein the operating mode acquisition module is used to acquire the current operating mode of the air purifier; the pet location acquisition module is used to acquire the pet's location information when the current operating mode of the air purifier is a guardian mode, wherein the location information is obtained using ultra-wideband indoor positioning technology based on a positioning tag carried by the pet; the judgment module is used to determine whether a preset guardian purification task trigger condition has been met based on the location information; and the purification task execution module is used to execute the guardian purification task when the guardian purification task trigger condition is met.

[0023] Thirdly, the present invention also provides a computer device, including 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 control method of the air purifier described in the first aspect or any corresponding embodiment.

[0024] Fourthly, the present invention also provides an air purifier, including the computer device of the third aspect.

[0025] Fifthly, the present invention also provides a computer-readable storage medium storing computer instructions for causing a computer to execute the control method of the air purifier described in the first aspect or any corresponding embodiment thereof.

[0026] In a sixth aspect, the present invention also provides a computer program product, including computer instructions for causing a computer to execute the control method of the air purifier described in the first aspect or any corresponding embodiment thereof. Attached Figure Description

[0034] 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.

[0035] According to an embodiment of the present invention, an embodiment of a control method for an air purifier 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.

[0036] This embodiment provides a control method for an air purifier, which can be used in air purifiers. Figure 1 This is a flowchart of an air purifier control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0037] Step S101: Obtain the current operating mode of the air purifier.

[0038] Specifically, the air purifier's operating modes include a normal mode without pet protection functionality, and a protection mode with pet protection functionality. For example, when the pet air purifier does not recognize a pet (smart pet collar), the air purifier operates in normal mode; when it recognizes a pet, the air purifier can be set to protection mode.

[0039] Step S102: When the air purifier is in guardian mode, obtain the pet's location information, which is obtained using ultra-wideband indoor positioning technology based on the positioning tag carried by the pet.

[0040] Specifically, indoor positioning of air purifiers mainly includes the positioning of the smart pet air purifier itself and different pets, as well as the pet air purifier's recognition of different pets. To obtain higher positioning accuracy, Ultra Wide Band (UWB) indoor positioning technology can be used. Based on the user's house type and size, three suitable UWB positioning base stations are selected and deployed reasonably in appropriate locations within the house. Simultaneously, to obtain the location information of the pet air purifier and different pets, positioning tags need to be embedded inside both the pet air purifier and the pet smart collar. Different pet collars are worn by different pets. The three positioning base stations obtain the relative position information of different positioning tags and transmit the relevant data to the data processing center via wireless transmission methods such as Wi-Fi. This data is then fed back to the relevant positioning system application software, thus enabling real-time acquisition of the specific indoor location information of the pet air purifier and different pets.

[0041] Step S103: Obtain a map, which is constructed using ultra-wideband indoor positioning technology and a lidar sensor carried in an air purifier.

[0042] Specifically, the map, also known as an indoor high-precision map, is mainly constructed using UWB technology and LiDAR sensors on pet air purifiers. It supports automatic updates of indoor maps to adapt to changes in home layout and other factors. It also supports the detection of dynamic obstacles and path optimization, thereby enabling dynamic planning of the air purifier's movement path.

[0043] Step S104: Determine whether the preset conditions for triggering the guardian purification task have been met based on the location information and map.

[0044] Specifically, the purification mission includes pet area purification missions and pet-following purification missions. Under the pet area purification mission, the pet air purifier can move automatically to different pet areas such as pet defecation areas and pet play areas to carry out purification work; the pet-following purification mission can be divided into pet return-following purification missions and pet exercise-following purification missions.

[0045] Step S105: When the conditions for triggering the Guardian Purification Task are met, execute the Guardian Purification Task.

[0046] The air purifier control method provided in this embodiment introduces ultra-wideband indoor positioning technology and fuses it with LiDAR sensors to construct a map. Combined with a positioning tag on the pet, it achieves precise location tracking, enhancing the air purifier's targeted purification capabilities for pet-friendly spaces while protecting user privacy. Simultaneously, this method can intelligently determine whether preset protective purification conditions are met, automatically executing corresponding purification tasks. This not only improves air purification efficiency but also enhances the intelligent level of air quality management in human-pet cohabitation environments, demonstrating promising application prospects and market promotion value.

[0047] This embodiment provides a control method for an air purifier, which can be used in air purifiers. Figure 2 This is a flowchart of another air purifier control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0048] Step S201: Obtain the current operating mode of the air purifier.

[0049] Step S202: When the air purifier is currently in guardian mode, obtain the pet's location information, which is obtained using ultra-wideband indoor positioning technology based on the positioning tag carried by the pet.

[0050] Step S203: Obtain a map, which is constructed using ultra-wideband indoor positioning technology and a lidar sensor carried in an air purifier.

[0051] Step S204: Determine whether the preset conditions for triggering the guardian purification task have been met based on the location information and map.

[0052] In one optional implementation, the guardian purification task includes a pet area purification task and a pet follower purification task; determining whether the preset guardian purification task triggering conditions have been met based on location information and the map includes the following steps:

[0053] Step S2041: Based on the location information and map, determine whether the pet's stay time in the preset pet activity area has reached the preset first time threshold. When the pet's stay time in the pet activity area reaches the first time threshold, it is determined that the trigger condition for the pet area purification task has been met.

[0054] Step S2042: Determine whether the pet has returned from outdoors or whether the duration of the pet's vigorous exercise has reached the preset second duration threshold based on the location information. When the pet returns from outdoors or the duration of the pet's vigorous exercise reaches the second duration threshold, it is determined that the triggering condition for the pet following the purification task has been met.

[0055] Specifically, for pets that frequently need outdoor exercise or certain types of pets, you can also choose a pet collar with built-in GPS positioning function. For pets that exercise outdoors, it can identify their behavior when going out and returning home, and record the pet's outdoor trajectory information.

[0056] Specifically, based on the pet's location information over a period of time, a spatial trajectory of the pet's movement can be generated. The pet's displacement speed can be calculated based on the pet's displacement time and trajectory length. When a preset speed threshold is reached, it can be determined that the pet is in a state of vigorous movement. Additionally, the complexity of the pet's displacement trajectory can be used as an auxiliary factor in the judgment, such as if the pet frequently changes direction or circles within a short period of time.

[0057] Step S205: When the triggering condition of the guardian purification task is met, determine whether there are other guardian purification tasks in the process of execution; if there are other guardian purification tasks in the process of execution, proceed to step S206; otherwise, proceed to step S209.

[0058] Step S206: Obtain the preset priority sorting rules.

[0059] This is because, in guardian mode, since guardian purification tasks can be triggered automatically, there may be multiple tasks running simultaneously. To ensure the orderly execution of these tasks, they need to be sorted according to a priority ranking rule. Specifically, tasks are executed based on their priority; tasks with the same priority are executed in the order they were triggered. For example, if a pet air purifier is performing a regular purification task when a guardian purification task is triggered, the current regular purification task is interrupted, and the guardian purification task is executed first. After the guardian purification task finishes, the interrupted regular purification task resumes execution. Step S207: Determine whether the priority of the guardian purification task is higher than other guardian purification tasks currently in execution according to the priority ranking rule; if the priority of the guardian purification task is higher than other guardian purification tasks currently in execution, proceed to step S209; otherwise, proceed to step S208.

[0060] Step S208: Continue to execute other guardian purification tasks. After the other guardian purification tasks are completed, proceed to step S209.

[0061] Step S209: Perform the guardian purification task.

[0062] In one optional implementation, performing the guardian purification task includes: when the triggering condition for the pet area purification task is met, controlling the air purifier to enter the pet activity area according to the map and performing a first purification treatment on the pet activity area until a preset purification effect is achieved; when the triggering condition for the pet follow purification task is met, controlling the air purifier to perform a second purification treatment according to the pet's movement path according to the map until a preset purification effect is achieved.

[0063] Specifically, the first purification treatment of the pet activity area includes: determining the purification type of the first purification treatment based on the pet activity area; obtaining the pet's personalized characteristics, and determining the first purification parameters of the purification type based on the personalized characteristics, wherein the personalized characteristics include at least one of the following: pet breed, pet age, pet health status, pet gender, and pet personality; the first purification parameters include at least one of the following: purification wind speed and purification duration; and using the first purification parameters to perform the first purification treatment on the pet activity area.

[0064] Specifically, controlling the air purifier to perform the second purification process according to the pet's movement path includes: acquiring the pet's personalized characteristics and determining the second purification parameters for the second purification process based on the personalized characteristics; wherein the personalized characteristics include at least one of the following: pet breed, pet age, pet health status, pet gender, and pet personality; the second purification parameters include at least one of the following: purification wind speed, following distance, following speed, and purification duration.

[0065] For example, the pet area purification task involves the pet air purifier automatically moving to different pet areas such as the pet waste disposal area and the pet play area to perform purification work. The automatic triggering conditions are as follows: When a pet is detected moving to the pet waste disposal area and staying there for a certain period of time, the area purification task for that area will be automatically triggered. The pet air purifier will move to the vicinity of the pet waste disposal area to deodorize and disinfect. After a certain period of purification, odor sensors such as TVOC will be used to detect odor indicators such as ammonia. If the levels drop below a safe threshold, the current purification task will automatically end or a new purification task will begin. If the levels do not drop below the safe threshold, the pet air purifier will continue purifying for the same period of time. The system will detect and remove odors until they drop below a safe threshold. When a certain number of pets move to the pet play area and stay there for a certain period of time, the system will automatically trigger a purification task for the pet play area. The pet air purifier will move to the vicinity of the pet play area to perform purification such as adsorption of loose pet hair. After a certain period of purification, the system will automatically detect whether the number of pets in the pet play area is at a preset value. If it is lower than the preset value, the current purification task will automatically end or the next purification task will begin. If it reaches the preset value, the same purification task will continue to be executed until the task ends. In addition, users can also actively control the pet air purifier to perform purification tasks for pet areas, including other pet areas.

[0066] The pet-following purification task allows the pet air purifier to follow the movement of a specific pet for purification. This includes pet return-following purification and pet movement-following purification tasks. For the pet return-following purification task, the automatic triggering conditions are as follows: Upon detecting a pet returning from outdoors, the task is automatically triggered. It performs purification tasks such as adsorbing loose hair, deodorizing, and disinfecting along the pet's movement path. A pet-following distance is set. When the distance between the pet air purifier and the pet is greater than the pet-following distance, the pet air purifier uses a high fan speed and maintains a relatively high movement speed. When the distance is less than the pet-following distance, it uses a low fan speed and maintains a relatively low movement speed. While ensuring a certain purification effect, it avoids stimulating pets with large airflow and noise, and stays near the pet to perform purification work. After a certain period of purification, it uses odor sensors such as TVOC to detect odor indicators such as ammonia. If the level drops below the safe threshold, it will automatically end the current purification task or start the next purification task. If the level does not drop below the safe threshold, the pet air purifier will continue to perform the same purification task. For the pet movement-following purification task, the automatic trigger condition is when the pet collar detects that the pet is moving quickly in the room for a certain period of time. The execution strategy of the pet regular following purification task is the same as the pet return-following purification task, only the trigger condition is different. Similarly, users can also actively control the pet air purifier to perform the pet regular following purification task for specific pets.

[0067] Furthermore, the air purifier should have personalized purification plans for different pets depending on their breed and type. For example, different pets have different coat types and activity ranges. Their age, health status, personality, and gender also affect their shedding volume, noise tolerance, and respiratory sensitivity. Therefore, purification parameters can be adjusted for different pets, such as purification duration, fan speed, and pet following distance. Different safe distances can also be set for different pets. When the air purifier is within this safe distance, the fan speed will adjust accordingly to avoid discomfort for older or easily stressed pets. Users can further edit and optimize purification parameters and provide feedback on the purification effect after the task is completed. The air purifier will automatically optimize the purification plan based on the feedback to achieve the best purification experience and effect for each pet. In addition, pet air purifiers can generate heat maps of pet gathering locations based on each pet's daily activity patterns, allowing users to more accurately divide different pet areas. They can also remind users to perform corresponding purification tasks and increase the frequency of reminders during allergy seasons such as spring or different pets' shedding periods, improving indoor purification effects while enhancing the comfort of pets' lives.

[0068] Step S210: Determine whether the pet has entered a preset pet restricted area based on the pet's location information and the map. The pet restricted area is determined based on the pet's activity permissions.

[0069] Step S211: When a pet enters the pet restricted area, pause the guardian purification task, control the air purifier to enter the pet restricted area, and execute the preset guidance task to guide the pet out of the pet restricted area; after the pet leaves the pet restricted area, continue to execute the guardian purification task.

[0070] In other words, when an alarm task is in effect, if the air purifier is performing a purification task, the current purification task will be interrupted and the alarm task will be executed first. Once the alarm task is cleared, the interrupted purification task will resume.

[0071] Specifically, after the high-precision indoor map is built, users can create different zoning schemes on the high-precision map of the house built by the pet air purifier. These mainly include user zone zoning and pet zone zoning. The user zone can be divided into living room, dining room, bedroom, balcony, kitchen, and toilet, etc. Areas where pets are prohibited can be set as pet no-go zones. The pet zone can be divided into rest area, defecation area, feeding area, and play area, etc. By using the pet's location information, such as the arrival and departure time of the pet in a certain area, a preliminary judgment of the pet's daily behavior can be made. Usually, long-term optimization and learning can further improve the more accurate identification and judgment of different daily behaviors of each pet, thereby triggering the pet air purifier to perform corresponding purification tasks or alarm tasks.

[0072] In one optional implementation, after performing the guardian purification task, the following steps are also included: determining whether the pet has gone out based on the pet's location information and map; when the pet goes out, determining whether the pet has permission to go out; when the pet does not have permission to go out, issuing a prompt message.

[0073] For example, different pet collars can be assigned to different pets based on their name, breed, breed, age, gender, personality, health status, as well as their access permissions to outside areas and user areas.

[0074] In other words, the Guardian Mode also includes alarm tasks, primarily pet outing alarms and pet restricted area alarms. For the pet outing alarm, the trigger condition is a pet without outing privileges leaving the house. The user will receive an alarm notification and real-time location information of the pet outdoors. Optionally, when the user approaches the pet, the pet collar can emit sound and light to help the user quickly locate its belongings. For the pet restricted area alarm, the trigger condition is a pet without permission entering the user's area, such as the bedroom, an unsealed balcony, or a regular balcony. The user will receive a restricted area alarm notification, and the pet air purifier will move to the vicinity of the corresponding user area, attracting the pet with specific sound and light effects or a specific scent, such as catnip, until the pet is led away from the restricted area.

[0075] In one optional implementation, the air purifier control method further includes the following steps: acquiring the air purifier's power information; determining whether the air purifier needs charging based on the power information; when the air purifier needs charging, pausing the protective purification task and controlling the air purifier to charge; and resuming the protective purification task after the air purifier has finished charging.

[0076] In other words, you can set a power threshold for charging and powering off the air purifier. When the air purifier's power is lower than the charging threshold, the air purifier will automatically interrupt the current purification task and create a charging task. When the power reaches the power-off threshold, the air purifier will automatically end the charging task and continue the previously interrupted purification task. The charging task has a lower priority than the alarm task but a higher priority than the purification task.

[0077] The air purifier control method provided in this embodiment introduces a priority judgment and scheduling mechanism for protective purification tasks. This ensures that the air purifier can dynamically adjust the task execution order according to preset rules when multiple tasks are running in parallel, effectively avoiding task conflicts and improving the coordination and execution efficiency of the system. Simultaneously, this mechanism can flexibly configure task priorities according to different scenarios, enhancing the air purifier's intelligent response capability and adaptability in complex human-pet cohabitation environments.

[0078] This embodiment provides a control method for an air purifier, which can be used in air purifiers. Figure 3 This is a flowchart of another air purifier control method according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the working task according to an embodiment of the present invention.

[0079] like Figure 3 As shown, the control method for an air purifier includes the following steps:

[0080] Step S301: Obtain the current operating mode of the air purifier. If the current operating mode of the air purifier is the protection mode, proceed to step S302; if the current operating mode of the air purifier is the normal purification mode, proceed to step S306.

[0081] Step S302: When the air purifier is in guardian mode, obtain the pet's location information, which is obtained using ultra-wideband indoor positioning technology based on the positioning tag carried by the pet.

[0082] Step S303: Obtain a map, wherein the map is constructed using ultra-wideband indoor positioning technology and a lidar sensor carried in an air purifier.

[0083] Step S304: Determine whether the preset conditions for triggering the guardian purification task have been met based on the location information and map.

[0084] Step S305: When the conditions for triggering the Guardian Purification Task are met, execute the Guardian Purification Task.

[0085] like Figure 4As shown, the air purifier's tasks are divided into purification and alarm tasks. The purification task can be further divided into normal purification and protective purification tasks. Normal purification tasks are initiated by the user, while protective purification tasks are primarily triggered automatically by the air purifier, but can also be initiated manually by the user. Protective purification tasks include pet area purification and pet-following purification. Under the pet area purification task, the air purifier can automatically move to different pet areas such as the pet's litter box and play area to perform purification work. The pet-following purification task can be divided into pet return-following purification and pet movement-following purification. Both follow the same execution strategy, differing only in triggering conditions. The former is triggered when the pet returns from outside, detected by the pet collar, while the latter is triggered when the pet is detected to be engaging in vigorous movement within a certain period. In addition to purification, the pet air purifier also has alarm functions, which can be divided into pet leaving the house alarm and pet restricted area alarm. The pet leaving the house alarm is triggered when a pet without permission leaves the house; the pet restricted area alarm is triggered when a pet without permission enters the user's area, such as the bedroom, an unsealed balcony, or a balcony.

[0086] Step S306: Obtain user instructions.

[0087] Specifically, in normal purification mode, users can manually execute the normal purification task of the air purifier through touch screen operation, mobile APP operation, and voice operation.

[0088] Step S307: Determine the purification range of the air purifier according to the user's instructions.

[0089] like Figure 4 As shown, the standard purification tasks include user area purification tasks and patrol purification tasks. Under user area purification tasks, the pet air purifier can purify the air at its current location or move to different user areas set by the user, such as the living room or bedroom. Under patrol purification tasks, the pet air purifier will move throughout the house while purifying, conducting a comprehensive patrol purification of all areas. Both specific areas of the house (such as the living room and bedroom) and other areas are within the purification scope.

[0090] Step S308: Obtain a map, wherein the map is constructed using ultra-wideband indoor positioning technology and a lidar sensor carried in an air purifier.

[0091] Step S309: Control the air purifier to perform normal purification tasks within the determined purification range according to the map.

[0092] Since the purification tasks of the pet air purifier in normal purification mode are all normal purification tasks that are actively invoked and executed by the user, the priority of different normal purification tasks is the same.

[0093] In summary, the air purifier control method provided by this invention has the following beneficial effects:

[0094] (1) Active air management is achieved through switching between normal mode and guard mode. Normal mode allows users to manually control regular purification tasks, while guard mode relies on UWB indoor positioning system and LiDAR SLAM technology to build a high-precision map and obtain pet location information in real time through smart pet collar. Combined with pet behavior analysis and air quality sensors, it automatically triggers guard purification tasks and alarm tasks. At the same time, it adopts multi-level task priority management, supports task interruption recovery and user-defined sorting, and ensures priority response to emergency events.

[0095] (2) For different pet purification tasks, personalized purification plans can be generated according to the characteristics of each pet. Users can further edit and optimize the relevant purification parameters on this basis, and provide feedback on the purification effect after the purification task is completed. The pet air purifier will automatically optimize the purification plan according to the feedback results to achieve the best purification experience and purification effect for each pet.

[0096] (3) An innovative pet smart safety alarm system was designed using GPS outdoor positioning technology and UWB indoor positioning technology. It includes a dual protection mechanism: first, an outing alarm, which monitors unauthorized pets in real time through a collar, and immediately pushes location information to the user once the pet leaves the house, and can remotely trigger the collar's sound and light prompts to assist in finding the pet; second, a restricted area alarm, which can actively move to the scene when a pet accidentally enters a restricted area such as a bedroom, and guide the pet back to a safe area through a combination of sound and light or by releasing attractive scents (such as catnip).
