[0002] With the improvement of people's living standards, pets have gradually become an indispensable member of many families. However, pets, such as cats, will generate a large amount of cat hair during their daily life. These cat hairs will float in the air, affecting the purification degree of indoor air and potentially threatening the health of family members. Especially for people with allergic constitutions, cat hair may trigger allergic reactions, such as sneezing, runny nose, skin itching and other symptoms.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] To solve the technical problems that the existing air purifiers have obvious limitations such as limited purification range, low purification efficiency, and poor purification effect, the present application provides a control method, a device, an air purifier, and a storage medium for an air purifier, which can achieve efficient purification processing, not only improving the purification efficiency but also enhancing the purification effect.

[0031] Figure 1 Flowchart of an embodiment of a control method for an air purifier provided by an embodiment of the present application. As Figure 1 shown, the method includes the following steps: Step 101, control the air purifier to move along a set inspection path, and control the air purifier to perform air purification operations at a first preset gear during the movement.

[0032] First, it should be noted that in the technical solution provided by the embodiments of the present application, the air purifier has an autonomous movement function. Then, in a complete air purification operation, the air purifier can move along a set inspection path and perform air purification operations during the movement. In this way, it is possible to achieve full-area air purification coverage of the target space and ensure the overall improvement of indoor air quality.

[0033] In one embodiment, the above-mentioned set inspection path refers to a mapped path of the room where the air purifier is located. For example, refer to Figure 2 , which is a schematic diagram of the set inspection path. Among them, the generation process of the set inspection path includes: taking a certain point of the air purifier in the room (such as the position starting from the charging stand) as the starting point of the journey and setting its coordinates as the origin (0, 0) of the plane rectangular coordinate system. During the movement of the air purifier, with the help of the built-in positioning and mapping module, it marks the area it passes through, and finally generates a map reflecting the spatial layout of the inspection area. Further, this map will be uploaded to the server and displayed in an equal-proportion form on the interaction interface of the mobile terminal (such as a dedicated application APP), facilitating the user to intuitively understand the inspection range and real-time position of the air purifier.

[0034] In addition, to ensure the normal operation of the intelligent functions of the air purifier, it is necessary to ensure its connection to the network. The specific network connection steps are as follows: Bluetooth pairing stage: After the air purifier is powered on, its built-in Bluetooth module will be activated and emit 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 emitted by the air purifier. Then, the user enters the SSID (Service Set Identifier) and password of the router that the air purifier needs to connect to in the Bluetooth pairing interface of the mobile terminal. After the Bluetooth module of the air purifier receives this information, it transmits it to the network connection module, and then establishes a stable wireless connection with the target router, thereby obtaining the network permission to access the server.

[0035] Device setting stage: On the mobile terminal, the user opens the application supporting the air purifier and selects the corresponding air purifier device from the device list. Subsequently, the user sets the room information to which the air purifier belongs in the application according to the actual living environment.

[0036] In step 101, during the movement of the air purifier along the set inspection path, control it to perform air purification operations at the 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 scenario, aiming to perform basic-level purification of the air during routine inspections to maintain the basic stability of air quality.

[0037] Step 102: Detect whether there are specific suspended substances in the air in the area where the air purifier is currently located.

[0038] In the technical solution provided by the embodiment of the present application, during the movement of the air purifier, it continuously detects whether there are specific suspended substances in the air in the area where it is currently located. Among them, the specific suspended substances can be minute particulate matters such as pet hairs, dander, pollen, dust, etc. that affect air quality.

[0039] In one embodiment, a suspended substance sensor mounted on the air purifier is used to detect whether there are specific suspended substances in the air in the area where it is currently located. The suspended substance sensor can be components such as a microwave radar, an infrared sensor, etc. Taking the microwave radar as an example, by emitting microwave signals, these microwave signals will be reflected after encountering suspended substances in the air, and the radar receives the echo signals reflected back. By analyzing and processing the echo signals, extracting characteristic information such as signal intensity and frequency change therein, and comparing it with the signal characteristics of the preset specific suspended substances. If the matching degree of the characteristics of the echo signal and the signal characteristics of the specific suspended substances reaches a certain threshold, it is determined that there are specific suspended substances in the air; otherwise, it is determined that there are none.

[0040] Step 103: If it is detected that there are specific suspended substances in the air, control the air purifier to stay at the current position and adjust to the second preset gear to perform the air purification operation, where the air purification intensity corresponding to the second preset gear is greater than the air purification intensity corresponding to the first preset gear.

[0041] By performing the above Step 102, once it is detected that there are specific suspended substances in the air, in order to more effectively purify the air in the area where it is currently located, perform Step 103: Control the air purifier to stop moving and stay at the position where the suspended substances are currently detected. At the same time, adjust the operating gear of the air purifier from the first preset gear to the second preset gear. Here, the second preset gear is a higher purification intensity gear set for the area where there are specific suspended substances, and its corresponding air purification intensity is greater than the first preset gear. At the second preset gear, the air purifier can increase the rotation speed of the fan, increase the air circulation speed, so that more air passes through the filter for filtration; or enhance the activity of the filter, improve the adsorption and filtration efficiency of the suspended substances; it may also increase the amount of negative ions generated, etc., to more thoroughly remove the specific suspended substances in the air and improve air quality.

[0042] Step 104: When it is determined that the air purifier has completed the air purification of the area where it is currently located, control the air purifier to continue moving along the set patrol path and repeat Steps 101 to 103.

[0043] In step 104, a certain determination mechanism is used to determine whether the air purifier has completed the air purification of the current area. For example, a detection time interval can be set. After the air purifier operates at the second preset gear for a period of time, the content of specific suspended matter in the air of this area is detected again by using the suspended matter sensor. If the content of the specific suspended matter is reduced below the preset safety threshold, or the specific suspended matter is not detected in consecutive multiple detections, it is determined that the air purifier has completed the air purification of this area.

[0044] Based on this, in one embodiment, determining that the air purifier has completed the air purification of the current area includes: not detecting the specific suspended matter in consecutive N detection cycles, where N is a natural number greater than 1; or, detecting that the concentration data of the specific suspended matter in the air of the current area where the air purifier is located is lower than the set threshold.

[0045] Once it is determined that the air purifier has completed the air purification of the current area, it will be controlled to continue moving along the previously set inspection path, enter the next area, and repeat the operations of steps 101 to 103, that is, perform air purification at the first preset gear, detect specific suspended matter, adjust the purification gear according to the detection results, etc., and continuously purify the air in the areas along the entire inspection path to ensure that the indoor air quality always remains at a good level.

[0046] The technical solution provided by the embodiments of the present application controls the air purifier to move along a set patrol path during a primary air purification operation, and controls the air purifier to perform air purification operations at a first preset gear during the movement, breaking the limitations of traditional fixed air purifiers, achieving full-area coverage of the target space, and greatly improving the comprehensiveness of air purification. At the same time, by detecting in real time whether there are specific suspended substances in the air in the area where the air purifier is currently located during the movement; if it is detected that there are specific suspended substances in the air, the air purifier is controlled to stay at the current position and adjusted to a second preset gear to perform air purification operations, where the air purification intensity corresponding to the second preset gear is greater than the air purification intensity corresponding to the first preset gear, realizing a dynamic purification adjustment mechanism. This dynamic purification adjustment mechanism enables the air purifier to automatically identify local pollution areas and perform focused and efficient purification treatment on local pollution areas, not only improving the purification efficiency but also enhancing the purification effect, and can effectively remove suspended substances such as pet hair in the air, and well improve the indoor air quality. When it is determined that the air purifier has completed the air purification of the area where it is currently located, the air purifier is controlled to continue to move along the set patrol path, and the steps of controlling the air purifier to perform air purification operations at the first preset gear during the movement and subsequent steps are repeated. This cyclic working mode enables the air purifier to continuously and automatically identify and purify pollutants in the air, realizing the comprehensive maintenance of indoor air quality.

[0047] Figure 3 It is a flowchart of an embodiment of another control method for an air purifier provided by the embodiments of the present application. Figure 3 The shown process is Figure 1 Based on the shown process, it includes the following steps: Step 301: Control the air purifier to move along a set patrol path, and control the air purifier to perform air purification operations at a first preset gear during the movement.

[0048] Step 302: Detect whether there are specific suspended substances in the air in the area where the air purifier is currently located.

[0049] For the detailed descriptions of Step 301 and Step 302, please refer to the relevant descriptions in the above embodiments, and will not be elaborated here.

[0050] Step 303: If it is detected that there are specific suspended substances in the air, control the air purifier to stay at the current position, adjust to a second preset gear to perform air purification operations, and record the current position of the air purifier as the adsorption event position.

[0051] During the operation of the air purifier, when specific suspended matter is detected in the air, in addition to controlling the air purifier to stay at the current position and adjust to the second preset gear to perform air purification operations, the current position of the air purifier will also be recorded as the adsorption event position. For example, record the position coordinates of the adsorption event position (or other parameters that can uniquely identify this position). 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.

[0052] Step 304: When it is determined that the air purifier has completed the air purification of the current area, control the air purifier to continue moving along the set patrol path, and repeat steps 301 to 303.

[0053] For the detailed description of step 304, please refer to the relevant description in the above embodiments, and it will not be elaborated here.

[0054] Step 305: After the current air purification work is completed, adjust the set patrol path 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.

[0055] In one embodiment, after the current air purification work is completed, the set patrol path will be adjusted according to the recorded adsorption event position (referring to the adsorption event position recorded during this air purification work), aiming to enable the air purifier to move along the adjusted set patrol 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.

[0056] Specifically, the adsorption event positions recorded in step 303 are often areas where specific suspended matter is relatively concentrated in the indoor environment, or areas with relatively serious air pollution, so the air purifier needs to pay more attention and purification treatment. Then, adjusting the set patrol path according to these positions aims to enable the air purifier to cover these key areas faster and more comprehensively in the next air purification work, so as to ensure the effective improvement of the air quality in these areas.

[0057] Among them, as an optional implementation method, the specific implementation of adjusting the set patrol path according to the recorded adsorption event position includes: for each recorded adsorption event position, perform the following operations: determine the distance between the adsorption event position and the starting position of the air purifier; sort the multiple recorded adsorption event positions in ascending order of distance; use a path planning algorithm to sequentially connect the sorted multiple adsorption event positions to generate an adjusted set patrol path.

[0058] Specifically, first determine the distance between the adsorption event location and the starting position of the air purifier. In a two-dimensional Cartesian coordinate system, both the adsorption event location 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 location and the starting position can be accurately obtained.

[0059] Then, sort the recorded multiple adsorption event locations in ascending order of distance to obtain an ordered sequence of adsorption event locations. Here, the sorting operation makes the adsorption event locations spatially ordered, facilitating the processing of subsequent path planning algorithms.

[0060] After sorting in ascending order of distance, use the path planning algorithm to sequentially connect the sorted multiple adsorption event locations to generate an adjusted set inspection path. This means that the air purifier can preferentially visit the adsorption event locations closer to the starting point during the inspection process. This sequential arrangement helps improve the overall purification efficiency of the air purifier.

[0061] Figure 3 In the process shown, when it is detected that there are specific suspended substances in the air and the air purifier is controlled to adjust to the second preset gear to perform the air purification operation, the current position of the air purifier is recorded as the adsorption event location. After the current air purification work is completed, according to the recorded adsorption event location, the set inspection path is adjusted so that the air purifier moves along the adjusted set inspection path during the next air purification work, realizing the optimization and adjustment of the set inspection path of the air purifier, and can significantly improve the air purification efficiency and purification effect of the air purifier in the indoor environment.

[0062] Figure 4 This is a flowchart of an embodiment of another control method for an air purifier provided by an embodiment of the present application. Figure 4 The process shown is Figure 1 Based on the process shown, it includes the following steps: Step 401: Control the air purifier to move along the set inspection path and control the air purifier to perform the air purification operation at the first preset gear during the movement.

[0063] Step 402: Detect whether there are specific suspended substances in the air in the area where the air purifier is currently located.

[0064] Step 403: If it is detected that there are specific suspended substances in the air, control the air purifier to stay at the current position, adjust to the second preset gear to perform the air purification operation, and record the current position of the air purifier as the adsorption event location.

[0065] Step 404: When it is determined that the air purifier has completed the air purification of the current area, control the air purifier to continue moving along the set inspection path, and repeat steps 401 to 403.

[0066] For the detailed descriptions of steps 401 to 404, please refer to the relevant descriptions in the above embodiments, and will not be elaborated here.

[0067] Step 405: After the current air purification work is completed, count the number of repeated records at the same adsorption event location as the adsorption times corresponding to the adsorption event location; adjust the set inspection path according to the recorded adsorption event location and the corresponding adsorption times.

[0068] In an embodiment, after a single air purification work is completed, all the recorded adsorption event locations are analyzed. Here, all the recorded adsorption event locations refer to the adsorption event locations recorded in multiple completed air purification works (for example, multiple air purification works completed in a recent period). For each adsorption event location, the number of times it is repeatedly recorded in multiple air purification works is counted through data retrieval and counting. For example, if a certain location is recorded 5 times during multiple inspections, it means the adsorption times at this location is 5. Among them, the adsorption times reflect the frequency of pollution at the adsorption event location during the air purification process. The more the adsorption times, the relatively worse the air quality at this location, or the greater the influence of the pollution source, and more attention and purification treatment are required by the air purifier. Thus, counting the adsorption times provides an important basis for adjusting the inspection path subsequently, enabling the air purifier to perform targeted path planning according to the pollution severity of different locations.

[0069] As an optional implementation manner, the specific implementation of adjusting the set inspection path according to the recorded adsorption event location and the corresponding adsorption times includes: for each recorded adsorption event location, perform the following operations: determine the distance between the adsorption event location and the starting position of the air purifier; according to the distance and the adsorption times corresponding to the adsorption event location, determine the path priority index corresponding to the adsorption event location; sort the multiple recorded adsorption event locations in descending order of the path priority index; based on the sorting result, use the path rule algorithm to generate the shortest inspection path including each recorded adsorption event location as the adjusted set inspection path.

[0070] The core of this implementation method lies in: by comprehensively considering the distance between the adsorption event location and the starting point location as well as the number of adsorption times, to determine the path priority index of each adsorption event location, and then generate an adjusted inspection path. The purpose of this adjusted inspection path setting is to enable the air purifier to complete the air purification task more efficiently. By optimizing the inspection path according to the number of adsorption times and the distance, the air purifier can reach the areas with serious pollution and relatively close distances first, improve the purification frequency and effect on these areas, thereby enhancing the overall air purification quality and efficiency, and providing a better indoor air environment for users.

[0071] Specifically, the path priority index is a comprehensive index that comprehensively considers the distance and the number of adsorption times. It can be calculated by the method of weighted summation. For example, let the weight of the distance be w1 and the weight of the number of adsorption times be w2, then the path priority index P = w1× + w2×n (where d is the distance and n is the number of adsorption times). Here, the closer the distance, the greater its impact on the path priority index; the more the number of adsorption times, the greater the impact on the path priority. That is to say, the positions with more adsorption times and closer distances will obtain a higher path priority index, indicating that these positions should be given priority in the inspection path planning. By adjusting the magnitudes of the weights w1 and w2, the relative importance of the distance and the number of adsorption times in the path priority index can be flexibly adjusted.

[0072] After that, sort the recorded multiple adsorption event locations in descending order of the path priority index. Based on the sorting result, use the path rule algorithm to generate the shortest inspection path that includes each recorded adsorption event location as the adjusted set inspection path. This method can, on the one hand, enable the air purifier to give priority to processing the areas with serious pollution and close distances, improving the rationality and effectiveness of the inspection path, and on the other hand, enable the air purifier to complete the purification of all key polluted areas with the shortest moving distance. This reduces the moving time and energy consumption of the air purifier and improves its working efficiency.

[0073] The above path planning algorithms are, for example: algorithms for finding the optimal path in a given space such as the traveling salesman problem algorithm, ant colony algorithm, genetic algorithm, etc. The embodiments of this application do not limit this.

[0074] Figure 4 The shown process fully considers factors such as the spatial distribution, distance, and number of adsorption times of the adsorption event locations to adjust the set inspection path, and can significantly improve the air purification efficiency and air purification effect of the air purifier in the indoor environment.

[0075] In any of the above embodiments, the specific implementation of adjusting to the second preset gear to perform air purification operations includes: determining the concentration data of specific suspended substances in the air in the area 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 air purification operations, wherein the purification intensity of the second preset gear is positively correlated with the concentration data.

[0076] Among them, the concentration data of specific suspended substances in the air can intuitively reflect the air pollution degree of the current area. The greater the concentration of specific suspended substances, the higher the air pollution degree of the current area. In this case, to avoid insufficient purification, a greater purification intensity can be adopted; while the smaller the concentration of specific suspended substances, the lower the air pollution degree of the current area. In this case, to avoid excessive purification, a smaller purification intensity can be adopted. Accordingly, the above embodiments propose to perform precise purification control according to the concentration data of specific suspended substances in the air, that is, the air pollution degree of the current area, to avoid insufficient purification or excessive purification, and improve the operating efficiency and energy saving of the air purifier.

[0077] As an optional implementation, a corresponding relationship between a series of concentration thresholds and different purification gears is preset in advance. After obtaining the concentration data of specific suspended substances in the current area, the concentration data is compared with the preset concentration thresholds. 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 the low gear, medium gear, and high gear in the second preset gear respectively. If the concentration data C ≤ C1, the second preset gear is determined to be the low gear; if C1 < C ≤ C2, it is determined to be the medium gear; if C > C2, it is determined to be the high gear. After determining the appropriate second preset gear according to the comparison result, a corresponding control instruction is sent to the control module of the air purifier. After receiving the instruction, the control module adjusts the air purifier to the determined second preset gear by adjusting the rotation speed of the fan, changing the adsorption mode of the filter, or adjusting the output intensity of the negative ion generator, etc., and starts to perform air purification operations.

[0078] The above embodiments realize dynamically determining the second preset gear according to the concentration data of specific suspended substances in the air and adjusting the operating state of the air purifier, realizing the adaptive adjustment of the purification intensity of the air purifier. Since the purification intensity of the second preset gear is positively correlated with the concentration data, that is, 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 areas with different pollution degrees. In areas with relatively light pollution, adopting a lower purification gear can reduce energy consumption and noise; while in areas with relatively heavy pollution, quickly increasing the purification intensity can quickly remove suspended substances in the air and effectively improve air quality. This intelligent adjustment mechanism improves the adaptability and practicality of the air purifier, providing a more comfortable and healthy indoor environment for users.

[0079] In summary, in this embodiment, by accurately detecting the concentration data of specific suspended substances in the air and dynamically adjusting the purification level of the air purifier according to the concentration data, precise control of the purification intensity of the air purifier is achieved, and the purification efficiency and effect of the air purifier are improved.
