[0002] With the improvement of people's living standards, pets have gradually become an indispensable member of many families. However, pets, such as cats, produce a large amount of cat hair in the process of daily life. These cat hairs float in the air, affecting the purification degree of indoor air, and may also pose a potential threat to the health of family members, especially for people with allergic constitution, cat hair may trigger allergic reactions, such as sneezing, runny nose, and skin itching.

[0003] Current air purifiers mainly adopt the method of placing the purifier in a certain place in the room, and then turning it on to adsorb cat hair and other suspended matter in the air through the built-in adsorption device.

[0081] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of protection of the present application.

[0082] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0083] To solve the technical problems of the air purifier in the prior art, such as limited purification range, low purification efficiency and purification effect, and other obvious limitations, the application provides an air purifier control method, device, air purifier and storage medium, which can achieve efficient purification processing, improve purification efficiency, and enhance purification effect.

[0084] Figure 1 An embodiment flowchart of an air purifier control method provided by the application is shown in FIG. 1. As shown in the figure, the method comprises the following steps: Figure 1

[0085] Step 101: Control the air purifier to move along a set inspection path, and control the air purifier to perform an air purification operation at a first preset gear during the movement.

[0086] Firstly, in the technical solution provided by the embodiments of the application, the air purifier has a self-moving function. Therefore, in a complete air purification work, the air purifier can move along a set inspection path and perform an air purification operation during the movement. In this way, air purification coverage of the whole target space can be achieved, and the overall improvement of indoor air quality can be ensured.

[0087] In an embodiment, the set inspection path refers to a mapped path of a room where the air purifier is located. For example, referring to FIG. 2, which is a schematic diagram of setting an inspection path. Figure 2 The generation process of the set inspection path comprises: taking a certain point (such as a position starting from a charging base) of the air purifier in the room as a starting point of a trip, and setting its coordinates as an origin (0, 0) of a plane rectangular coordinate system. During the movement of the air purifier, the positioning and mapping module built-in the air purifier marks the area passed through, and finally generates a map reflecting the spatial layout of the inspection area. Further, the map will be uploaded to a server and displayed on the interactive interface of a mobile terminal (such as a special application APP) in a proportional form, so as to facilitate the user to intuitively understand the inspection range and real-time position of the air purifier.

[0088] In addition, in order to ensure the normal operation of the intelligent function of the air purifier, it is necessary to ensure that the air purifier is connected to the network. The specific network connection steps are as follows:

[0089] ​Bluetooth pairing stage: after the air purifier is powered on, the built-in Bluetooth module is activated and sends out a Bluetooth signal. The user uses a mobile terminal (such as a smart phone) to turn on the Bluetooth function and search for the Bluetooth signal sent out by the air purifier. Then, the user inputs the SSID (Service Set Identifier) and password of the router required to be connected by the air purifier in the Bluetooth pairing interface of the mobile terminal. After the Bluetooth module of the air purifier receives the information, it is transmitted to the network connection module, and a stable wireless connection with the target router is established, thereby obtaining the network access permission of the server.

[0090] Device setting stage: on the mobile terminal, the user opens the application program matched with the air purifier, and selects the corresponding air purifier device from the device list. Then, the user sets the room information to which the air purifier belongs in the application program according to the actual living environment.

[0091] In step 101, the air purifier moves along the set inspection path, and controls the air purifier to perform the air purification operation at a first preset gear. Optionally, the first preset gear is a relatively low purification intensity gear preset according to the performance of the air purifier and the actual use scene, which is used to perform basic level purification on the air in the routine inspection process, so as to maintain the basic stability of the air quality.

[0092] Step 102, detecting whether there is a specific suspended matter in the air of the region where the air purifier is currently located.

[0093] In the technical scheme provided by the embodiment of the application, the air purifier detects in real time whether there is a specific suspended matter in the air of the region where the air purifier is currently located during the movement of the air purifier. The specific suspended matter can be pet hair, dander, pollen, dust and other small particulate matter that affects air quality.

[0094] In an embodiment, a suspended matter sensor carried on the air purifier is used to detect whether there is a specific suspended matter in the air of the region where the air purifier is currently located. The suspended matter sensor can be a microwave radar, an infrared sensor or the like. Taking the microwave radar as an example, microwave signals are emitted, and the microwave signals are reflected when encountering suspended matter in the air, and the radar receives the reflected echo signals. By analyzing and processing the echo signals, the characteristic information such as signal strength and frequency change is extracted, and is compared with the signal characteristics of the specific suspended matter preset in advance. If the characteristic of the echo signal matches the signal characteristics of the specific suspended matter to a certain threshold, it is determined that there is a specific suspended matter in the air; otherwise, it is determined that there is not.

[0095] If the specific suspended matter is detected in the air, the air purifier is controlled to remain at the current position and adjusted to a second preset gear to perform air purification operation, wherein the air purification strength corresponding to the second preset gear is greater than that corresponding to the first preset gear.

[0096] By performing the step 102, once the specific suspended matter is detected in the air, in order to more effectively purify the air in the current area, the step 103 is performed: the air purifier is controlled to stop moving and remain at the position where the suspended matter is currently detected. At the same time, the running gear of the air purifier is adjusted from the first preset gear to the second preset gear. Here, the second preset gear is a higher purification strength gear set for the area where the specific suspended matter exists, and the corresponding air purification strength is greater than that of the first preset gear. Under the second preset gear, the air purifier can increase the speed of the fan, increase the air circulation speed, make more air pass through the filter screen for filtering, or enhance the activity of the filter screen, improve the adsorption and filtering efficiency of the suspended matter, or increase the amount of negative ions, etc., so as to more thoroughly remove the specific suspended matter in the air and improve the air quality.

[0097] When it is determined that the air purifier has completed the air purification in the current area, the air purifier is controlled to continue moving along the set patrol path and repeat the steps 101 to 103.

[0098] In the step 104, a certain determination mechanism is used to determine whether the air purifier has completed the air purification in the current area. For example, a detection time interval can be set, and after the air purifier runs at the second preset gear for a period of time, the content of the specific suspended matter in the air of the area is detected again by using the suspended matter sensor. If the content of the specific suspended matter is reduced to below the preset safety threshold, or the specific suspended matter is not detected for a plurality of consecutive times, it is determined that the air purifier has completed the air purification in the area.

[0099] Based on this, in an embodiment, determining that the air purifier has completed the air purification in the current area includes: the specific suspended matter is not detected in consecutive N detection periods, wherein N is a natural number greater than 1; or the concentration data of the specific suspended matter in the air of the current area of the air purifier is detected to be lower than a set threshold.

[0100] Once it is determined that the air purifier has completed the air purification in the current area, it is controlled to continue moving along the previously set patrol path, enter the next area, and repeat the operations of the steps 101 to 103, i.e., air purification at the first preset gear, detection of the specific suspended matter, adjustment of the purification gear according to the detection result, etc., to continuously purify the air in the areas on the entire patrol path, so as to ensure that the indoor air quality is always maintained at a good level.

[0101] The technical scheme provided by the embodiments of the present application breaks the limitation of the traditional fixed air purifier, realizes full-area coverage of the target space, and greatly improves the comprehensiveness of air purification. Meanwhile, by detecting whether there is specific suspended matter in the air in the current area of the air purifier in real time during the movement, if the specific suspended matter is detected in the air, the air purifier is controlled to remain at the current position and is adjusted to the second preset gear to perform the air purification operation, wherein the air purification intensity corresponding to the second preset gear is greater than the air purification intensity corresponding to the first preset gear, thereby realizing a dynamic purification adjustment mechanism. The dynamic purification adjustment mechanism enables the air purifier to automatically identify the local pollution area and perform key and efficient purification treatment on the local pollution area, thereby improving the purification efficiency and enhancing the purification effect, effectively removing the suspended matter such as pet hair in the air, and greatly improving the indoor air quality. When it is determined that the air purifier has completed the air purification of the current area, the air purifier is controlled to continue moving along the set inspection path and repeatedly perform the step of controlling the air purifier to perform the air purification operation at the first preset gear during the movement and the subsequent steps. The cyclic working mode enables the air purifier to continuously and automatically identify and purify the pollutants in the air, thereby realizing comprehensive maintenance of the indoor air quality.

[0102] Figure 3 An embodiment flowchart of another air purifier control method provided by the embodiments of the present application is shown. Figure 3 The flowchart shown in Figure 1 On the basis of the flowchart shown in

[0103] Step 301: Control the air purifier to move along a set inspection path, and control the air purifier to perform an air purification operation at a first preset gear during the movement.

[0104] Step 302: Detect whether there is specific suspended matter in the air in the current area of the air purifier.

[0105] The detailed description of steps 301 and 302 can be referred to the related description in the above embodiments, which will not be repeated here.

[0106] Step 303: If the specific suspended matter is detected in the air, the air purifier is controlled to remain at the current position and is adjusted to a second preset gear to perform the air purification operation, and the current position of the air purifier is recorded as an adsorption event position.

[0107] In the operation of the air purifier, when it is detected that there is a specific suspended matter in the air, in addition to controlling the air purifier to stay at the current position and adjusting to the second preset gear to perform air purification operation, the current position of the air purifier is also recorded as an adsorption event position. For example, the position coordinates of the adsorption event position (or other parameters that can uniquely identify the position) are recorded. These position coordinates constitute a key data set reflecting the distribution characteristics of specific suspended matter in the room, providing a data basis for subsequent analysis and decision-making.

[0108] Step 304: When it is determined that the air purifier has completed air purification in the current area, the air purifier is controlled to continue moving along the set inspection path and repeat steps 301-303.

[0109] For a detailed description of step 304, please refer to the relevant description in the above embodiments, which will not be repeated here.

[0110] Step 305: After the current air purification work is completed, the set inspection path is adjusted according to the recorded adsorption event position, so that the air purifier moves along the adjusted set inspection path in the next air purification work.

[0111] In an embodiment, after the current air purification work is completed, the set inspection path will be adjusted according to the recorded adsorption event position (referring to the adsorption event position recorded in the current air purification work), so that the air purifier can move along the adjusted set inspection path in the next air purification work. This step improves the intelligence and adaptability of the air purifier, and can further improve the air purification efficiency and effect.

[0112] Specifically, the adsorption event position recorded in step 303 is often an area where the distribution of specific suspended matter in the indoor environment is relatively dense, which can also be said to be an area where air pollution is relatively serious, so it needs more attention and purification treatment from the air purifier. Then, according to these positions, the set inspection path is adjusted, so that the air purifier can cover these key areas more quickly and comprehensively in the next air purification work, thereby ensuring that the air quality in these areas is effectively improved.

[0113] Among them, as an optional implementation, the specific implementation of adjusting the set inspection path according to the recorded adsorption event position includes: for each recorded adsorption event position, the following operations are performed: determining the distance between the adsorption event position and the starting position of the air purifier; sorting the recorded multiple adsorption event positions in order of distance from small to large; using a path planning algorithm to sequentially connect the sorted multiple adsorption event positions to generate an adjusted set inspection path.

[0114] Specifically, first, the distance between the adsorption event position and the starting position of the air purifier is determined. In a plane rectangular coordinate system, both the adsorption event position and the starting position of the air purifier can be represented by coordinates (x, y). By calculating the Euclidean distance between the two points, the spatial distance between the adsorption event position and the starting position can be accurately obtained.

[0115] Then, the recorded multiple adsorption event positions are sorted in order of distance from small to large, obtaining an ordered adsorption event position sequence. Here, the sorting operation makes the adsorption event positions present an ordered distribution in space, facilitating the processing of subsequent path planning algorithms.

[0116] After sorting according to the distance from small to large, the sorted multiple adsorption event positions are sequentially connected using a path planning algorithm to generate an adjusted set patrol path. This means that the air purifier can visit the adsorption event positions closer to the starting point first during the patrol process. This sequential arrangement helps improve the overall purification efficiency of the air purifier.

[0117] Figure 3 The flowchart shows that in the case of detecting the presence of a specific suspended matter in the air, the air purifier is controlled to adjust to the second preset gear to perform air purification operation, the current position of the air purifier is recorded as the adsorption event position, and after the current air purification work is completed, the set patrol path is adjusted according to the recorded adsorption event position, so that the air purifier moves along the adjusted set patrol path in the next air purification work, realizing the optimization adjustment of the set patrol path of the air purifier, and significantly improving the air purification efficiency and purification effect of the air purifier in the indoor environment.

[0118] Figure 4 Another embodiment flowchart of the control method of the air purifier provided by the embodiments of the present application. Figure 4 The flowchart shown in Figure 1 Based on the flowchart shown in

[0119] Step 401, control the air purifier to move along the set patrol path, and control the air purifier to perform air purification operation at the first preset gear during the movement.

[0120] Step 402, detect whether there is a specific suspended matter in the air in the area where the air purifier is currently located.

[0121] Step 403, if the specific suspended matter is detected in the air, the air purifier is controlled to remain at the current position, and is adjusted to the second preset gear to perform air purification operation, and the current position of the air purifier is recorded as the adsorption event position.

[0122] Step 404: When it is determined that the air purifier has completed air purification in the current area, the air purifier continues to move along the set inspection path and repeats steps 401-403.

[0123] The detailed description of steps 401-404 can be found in the relevant description in the above embodiments, which will not be repeated here.

[0124] Step 405: After the current air purification work is completed, the number of repeated records of the same adsorption event position is counted as the adsorption number corresponding to the adsorption event position; and the set inspection path is adjusted according to the recorded adsorption event positions and the corresponding adsorption numbers.

[0125] In an embodiment, after completing an air purification work, all recorded adsorption event positions are analyzed. Here, all recorded adsorption event positions refer to the adsorption event positions recorded in multiple air purification works (for example, multiple air purification works completed in a recent period of time). For each adsorption event position, the number of times the position is repeatedly recorded in multiple air purification works is counted by data retrieval and counting. For example, if a position is recorded 5 times in multiple inspections, it means that the adsorption number of the position is 5. The adsorption number reflects the frequency of pollution of the adsorption event position in the air purification process. The more the adsorption number, the worse the air quality of the position, or the greater the impact of the pollution source, which requires more attention and purification treatment by the air purifier. Therefore, counting the adsorption number provides an important basis for subsequent adjustment of the inspection path, so that the air purifier can plan the path according to the pollution severity of different positions.

[0126] As an optional implementation, the specific implementation of adjusting the set inspection path according to the recorded adsorption event positions and the corresponding adsorption numbers includes: for each recorded adsorption event position, the following operations are performed: determining the distance between the adsorption event position and the starting position of the air purifier; determining the path priority index corresponding to the adsorption event position according to the distance and the adsorption number corresponding to the adsorption event position; sorting the multiple recorded adsorption event positions in descending order of path priority index; and generating a shortest inspection path containing each recorded adsorption event position as the adjusted set inspection path by using a path rule algorithm based on the sorting result.

[0127] The core of this implementation method is to determine the path priority index of each adsorption event location by comprehensively considering the distance between the adsorption event location and the starting location and the number of adsorptions, and then generate an adjusted inspection path. The purpose of adjusting the inspection path is to enable the air purifier to complete the air purification task more efficiently. By optimizing the inspection path according to the number of adsorptions and distance, the air purifier can prioritize reaching areas that are heavily polluted and close in distance, increase the purification frequency and effect of these areas, thereby improving the overall air purification quality and efficiency, and providing users with a better indoor air environment.

[0128] Specifically, the path priority index is a comprehensive index that takes into account the distance and the number of adsorptions. It can be calculated by weighted summation. For example, if the weight of the distance is w1 and the weight of the number of adsorptions is w2, then the path priority index P = w1× +w2×n (where d is the distance and n is the number of adsorptions). Here, the closer the distance, the greater its impact on the path priority index; the greater the number of adsorptions, the greater the impact on the path priority. In other words, locations with a high number of adsorptions and a close distance receive a higher path priority index, indicating that these locations should be prioritized in inspection route planning. By adjusting the weights w1 and w2, the relative importance of distance and number of adsorptions in the path priority index can be flexibly adjusted.

[0129] The multiple recorded adsorption event locations are then sorted from highest to lowest according to their path priority index. Based on the sorting results, a path rule algorithm is used to generate the shortest inspection path encompassing each recorded adsorption event location, which serves as the adjusted set inspection path. This approach allows the air purifier to prioritize heavily polluted and nearby areas, improving the rationality and effectiveness of the inspection path. It also allows the air purifier to complete the purification of all key polluted areas with the shortest possible travel distance. This reduces the air purifier's travel time and energy consumption, improving its efficiency.

[0130] The above-mentioned path planning algorithm is, for example, a traveling salesman problem algorithm, an ant colony algorithm, a genetic algorithm, etc., which are used to find the optimal path in a given space. The embodiments of the present application do not limit this.

[0131] Figure 4 The process shown fully considers factors such as the spatial distribution of adsorption event locations, distance, and number of adsorption times to adjust the inspection path, which can significantly improve the air purification efficiency and air purification effect of the air purifier in the indoor environment.

[0132] In any of the above embodiments, the specific implementation of adjusting the air purifier to the second preset gear to perform the air purification operation includes: determining concentration data of a specific suspended matter in the air in the region where the air purifier is currently located; determining the second preset gear according to the concentration data, and controlling the air purifier to adjust to the second preset gear to perform the air purification operation, wherein the purification intensity of the second preset gear is in a positive correlation with the concentration data.

[0133] The concentration data of the specific suspended matter in the air can directly reflect the air pollution degree of the current region. The greater the concentration of the specific suspended matter, the higher the air pollution degree of the current region. In this case, a larger purification intensity can be used to avoid insufficient purification. The smaller the concentration of the specific suspended matter, the lower the air pollution degree of the current region. In this case, a smaller purification intensity can be used to avoid excessive purification. Accordingly, the above embodiments propose to perform accurate purification control according to the concentration data of the specific suspended matter in the air, i.e., the air pollution degree of the current region, to avoid insufficient purification or excessive purification, and to improve the operation efficiency and energy saving of the air purifier.

[0134] As an optional implementation, a series of concentration threshold values and corresponding relationships with different purification gears are preset. After obtaining the concentration data of the specific suspended matter in the current region, the concentration data is compared with the preset concentration threshold values. For example, a low concentration threshold C1, a medium concentration threshold C2, and a high concentration threshold C3 are set, and the corresponding purification gears are low, medium, and high gears in the second preset gears, respectively. If the concentration data C≤C1, the second preset gear is determined to be the low gear; if C1

[0135] The above embodiments achieve dynamic determination of the second preset gear according to the concentration data of the specific suspended matter in the air and adjustment of the operation state of the air purifier, and achieve adaptive adjustment of the purification intensity of the air purifier. Since the purification intensity of the second preset gear is in a positive correlation with the concentration data, i.e., the higher the concentration, the greater the purification intensity, this adjustment method can ensure that the air purifier can achieve the best purification effect in regions with different pollution degrees. In a region with lighter pollution, a lower purification gear can be used to reduce energy consumption and noise; and in a region with heavier pollution, the purification intensity can be quickly increased to quickly remove suspended matters in the air and effectively improve air quality. This intelligent adjustment mechanism improves the adaptability and practicality of the air purifier, and provides a more comfortable and healthy indoor environment for users.

[0136] In summary, the embodiment realizes accurate control of the air purifier purification strength by accurately detecting concentration data of specific suspended matters in the air and dynamically adjusting the purification gear of the air purifier according to the concentration data, and improves the purification efficiency and purification effect of the air purifier.
