[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the implementation method of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] Example 1

[0049] With the rapid development of information technology in recent years, smart homes have gradually become an indispensable part of people's lives. To solve the problems of poor indoor air quality and high levels of harmful gases such as formaldehyde, people usually place one or more air purifiers indoors to purify the indoor air. Current air purifiers are more effective in purifying the air in small, enclosed rooms. However, in open environments, air purifiers can only purify the air in the area around them. The air quality away from the air purifier does not change much, and the air purification range is small. In addition, the air quality at each location in the space is inconsistent, and the degree of purification required varies. For example, corners away from windows and doors and near some new furniture have less air circulation and poorer air quality, requiring purification in key areas, but existing technologies do not have such a function.

[0050] The present invention utilizes a combined air purifier to purify indoor air, ensuring maximum purification at every location. An auxiliary purifier monitors the air quality throughout the room, and the main purifier, based on the test results, moves to areas with poor air quality for focused purification. The auxiliary purifier is equipped with independent purification units, allowing for individual purification in areas with limited air circulation, such as corners and under coffee tables. To ensure maximum air purification throughout the room, an air circulation blade is installed on the auxiliary purifier to accelerate air circulation, thereby effectively addressing the problem of limited indoor air purification range.

[0051] Based on the above ideas, an embodiment of the present invention provides an air purifier control method, which is applied to a first purifier, such as Figure 1 As shown, the air purifier control method of this embodiment includes step S101, and the specific content of this step is described in detail below:

[0052] Step S101 , when a preset instruction is received, the first purifier is controlled to move in the area to be purified according to a pre-planned path, and the first purifier is controlled to purify the air in the area to be purified during the movement.

[0053] In this embodiment, the preset command can be a "whole house purification" command or a "window purification" command sent by the user, i.e., a command to purify the room while maintaining indoor air circulation. The air purifier's control panel or remote control can be provided with a corresponding function button, through which the user sends the preset command to the first purifier. After receiving the command, the first purifier begins to move indoors along a pre-planned path, and comprehensively purifies the indoor air during the movement.

[0054] The pre-planned path is automatically planned by the first purifier based on the indoor layout. This is achieved through a grid-based path planning algorithm. This algorithm uses a grid-based scanning method to complete the task of covering the entire area to be purified. The area to be purified is divided into many small grid areas, and the system automatically saves the coordinate data of each grid area.

[0055] In this embodiment, a "regional purification" function button can also be set on the control panel or remote control of the air purifier. When the user selects this function, the first purifier no longer performs whole-house purification. In actual application, the user can select the corresponding function according to actual needs.

[0056] In this embodiment, the first purifier is also called an auxiliary purifier, and its structural diagram is as follows: Figure 3 、 Figure 4 and Figure 5 shown.

[0057] As described above, the pre-planned path divides the area to be purified into a plurality of grid areas. Under this premise, in order to classify the air quality levels of the area to be purified so as to more effectively purify the area to be purified, the method of this embodiment further includes: controlling the first purifier to detect the air quality of each grid area while controlling the first purifier to move along the pre-planned path within the area to be purified; and dividing the area to be purified into a plurality of units to be purified with different air quality levels based on the air quality of each grid area, so that the second purifier purifies the air in the units to be purified in order of the air quality levels from low to high.

[0058] Specifically, as the first purifier moves around the room and comprehensively purifies the air in various areas, it also detects the air quality of each grid area. This air quality information includes data such as formaldehyde concentration and PM2.5 concentration. Based on this detected data, the first purifier divides the indoor area into units with different air quality levels to be purified, for example, high air quality units, medium air quality units, and low air quality units, and sends this information and the corresponding location coordinates to the second purifier. Based on the received information, the second purifier first moves to the low air quality unit for air purification, then moves to the medium air quality unit for air purification, and finally purifies the high air quality unit, thereby more comprehensively and effectively purifying the air in the entire house.

[0059] In this embodiment, the second purifier is also called the main purifier, and its structural diagram is as follows: Figure 3 shown.

[0060] In order to accelerate the degradation of formaldehyde in the air and to perform more effective air purification, Figure 3 As shown, an ultraviolet lamp module is provided at the air outlet position inside the second purifier of this embodiment, and the ultraviolet lamp module is used to accelerate the degradation of formaldehyde. Under this structure, for each unit to be purified, the second purifier uses the following method to purify the air of the unit to be purified: Figure 2 As shown, during the process of the second purifier purifying the air of the unit to be purified, the current formaldehyde concentration in the air is detected in real time as the first formaldehyde concentration; it is determined whether the first formaldehyde concentration is greater than or equal to a preset concentration threshold; when the first formaldehyde concentration is greater than or equal to the preset concentration threshold, the ultraviolet lamp module is turned on; when the first formaldehyde concentration is less than the preset concentration threshold, the second purifier moves to the next unit to be purified for air purification.

[0061] In order to further accelerate the degradation of formaldehyde in the air and to perform more effective air purification on each unit to be purified, the second purifier further purifies the air of each unit to be purified in the following manner: Figure 2 As shown, the current formaldehyde concentration at the air outlet position inside the second purifier is detected in real time as the second formaldehyde concentration; it is determined whether the second formaldehyde concentration is greater than or equal to the preset concentration threshold; when the second formaldehyde concentration is greater than or equal to the preset concentration threshold, the power of the ultraviolet lamp module is increased.

[0062] Specifically, if Figure 3 As shown, a photocatalyst filter is also installed at the air outlet position inside the second purifier. The above-mentioned accelerated degradation of formaldehyde by the ultraviolet lamp module is actually achieved by irradiating the photocatalyst filter with ultraviolet light, generating ozone through the photocatalyst, and then oxidizing and degrading harmful substances such as formaldehyde and benzene through ozone. Its specific working principle is that when the photocatalyst (TiO2) is irradiated by ultraviolet light, the electrons in the valence band will be excited to the conduction band, forming a negatively charged highly active electron ecb - , and at the same time generate positively charged holes hvb in the valence band + Under the action of the electric field in the system, electrons and holes are separated. According to the thermodynamic theory, the hvb distributed on the surface + Water can be oxidized into hydroxyl radicals and reactive oxygen species. Reactive oxygen species combine with oxygen in the air to form ozone. Ozone has extremely strong oxidizing properties and can oxidize and degrade harmful substances such as formaldehyde and benzene. Increasing the power of the UV lamp module can further increase the degradation rate of harmful substances such as formaldehyde and benzene.

[0063] In order to enable the second purifier to accurately move to the target unit to be purified, in this embodiment, before the second purifier purifies the air in the unit to be purified, the second purifier is also used to: receive the location information of the unit to be purified sent by the first purifier; and move to the unit to be purified based on the location information.

[0064] Specifically, when the first purifier divides the entire house into multiple units to be purified during the mobile air purification process, it sends the location information of each unit to be purified and the air quality level information corresponding to the purification unit to the second purifier. The second purifier first moves to the unit to be purified with the worst air quality to purify the air based on the received information. When the second purifier purifies the air of a unit to be purified, the formaldehyde detection device set on the shell of the second purifier detects the current formaldehyde concentration in the air in real time. When the formaldehyde concentration is greater than or equal to the preset concentration threshold, for example, greater than or equal to 1.2 mg / m 3 When the formaldehyde concentration is less than 1.2 mg / m 3 When the UV lamp module is turned off, the second purifier moves to the next unit to be purified to purify the air. In addition, during the above process, the formaldehyde detection device set at the air outlet inside the second purifier detects the current formaldehyde concentration at the air outlet inside the second purifier in real time, that is, the formaldehyde concentration in the purified air. When the formaldehyde concentration is greater than or equal to 1.2 mg / m 3 When the air is heated, the power of the UV lamp module is increased to further accelerate the degradation of formaldehyde, so that the air quality is further effectively improved.

[0065] To accelerate air circulation and further effectively purify the air, the top of the first purifier described in this embodiment is equipped with fan blades for accelerating air circulation. In this structure, for each unit to be purified, while the second purifier is purifying the air in that unit, the method described in this embodiment further includes: obtaining the area of ​​the unit to be purified; determining whether the area of ​​the unit to be purified is greater than or equal to a first preset area threshold; when the area of ​​the unit to be purified is greater than or equal to the first preset area threshold, controlling the first purifier to move to the unit to be purified; and controlling the operation of the fan blades.

[0066] Specifically, when the second purifier purifies the air of a unit to be purified, the first purifier obtains the area of ​​the unit to be purified through the grid area described above. When the area of ​​the unit to be purified is greater than or equal to the first preset area threshold, for example, greater than or equal to 10m 2At this time, the first purifier will move to the unit to be purified to assist the second purifier in purification. At the same time, the fan blades of the first purifier will start to run to accelerate the air circulation of the unit to be purified, thereby more effectively purifying the air in the area.

[0067] In order to carry out more effective air evolution for units to be purified with a large area, for each unit to be purified, during the process of the second purifier performing air purification on the unit to be purified, the method described in this embodiment also includes: determining whether the area of ​​the unit to be purified is greater than or equal to a second preset area threshold; when the area of ​​the unit to be purified is greater than or equal to the second preset area threshold, increasing the operating power of the fan blade; wherein, the second preset area threshold is greater than the first preset area threshold.

[0068] Specifically, when the area of ​​a unit to be purified is greater than or equal to the second preset area threshold, for example, greater than or equal to 15m 2 When the air is flowing, the first purifier will automatically increase the operating power of the fan blades to provide a larger air volume to effectively accelerate the air circulation in the large area.

[0069] In order to change the circulation direction of the air and purify the air more effectively, the method described in this embodiment also includes: after controlling the operation of the fan blade for a preset time period, adjusting the operating angle of the fan blade to change the circulation direction of the air; wherein the operating angle of the fan blade is the angle between the fan blade and the horizontal direction.

[0070] Specifically, the initial operating angle of the fan blade is 0°, that is, the fan blade runs in the horizontal direction. Figure 4 As shown. After the fan blades have been running for a period of time, the first purifier automatically adjusts the operating angle of the fan blades to change the air circulation direction around the first purifier. In this embodiment, the operating angle of the fan blades can be 0 to 90 degrees. In a preferred embodiment, the operating angle of the fan blades can be changed in order of 30 degrees, 60 degrees, and 90 degrees to achieve a better purification effect. The schematic diagram when the fan blades are running at an angle of 90 degrees is shown as follows. Figure 5 Of course, in actual applications, in addition to the above-mentioned 30°, 60°, and 90° angle changes, other angle values ​​can also be used to change the operating angle of the fan blades, and this embodiment does not make specific restrictions on this.

[0071] See also Figure 3 The specific structures of the first purifier (i.e., auxiliary purifier) ​​and the second purifier (i.e., main purifier) ​​in this embodiment are described in detail below:

[0072] In this embodiment, the first purifier and the second purifier are wirelessly connected, enabling wireless communication between them. A chamber 8 for accommodating the first purifier is provided at the bottom of the second purifier. A folding plate 24 is provided at the bottom edge of the chamber 8. When unfolded, the folding plate 24 allows the first purifier to be moved into or out of the chamber 8.

[0073] In this embodiment, the accommodating cavity 8 is provided with charging contacts 10, and the first purifier is provided with contact-type charging connectors 9 that match the charging contacts 10. To ensure timely charging of the first purifier, the first purifier in this embodiment is further configured to: upon detecting that the charge level of the first purifier is less than a preset charge threshold, control the first purifier to move to the accommodating cavity 8 and electrically connect the charging connector 9 to the charging contacts 10.

[0074] In this embodiment, the first purifier and the second purifier are both provided with formaldehyde detection devices 11, 13, PM2.5 detection devices 12, 14, and an infrared detection device 20. The infrared detection device 20 is used to detect obstacles to prevent the first purifier or the second purifier from colliding with the obstacles during movement.

[0075] In addition to the above-mentioned infrared detection device, this embodiment can also use visual recognition technology or structured light to detect obstacles. Among them, visual recognition technology uses computer vision technology to identify and understand image data. This technology enables the machine to automatically identify the content in the image by capturing, extracting and analyzing image information, thereby automatically identifying or detecting target objects or features, and thus effectively detecting obstacles. Structured light is a system structure composed of a projector and a camera. After the projector projects specific light information onto the surface of an object and the background, the camera collects it and calculates the object's position, depth and other information based on the changes in the light signal caused by the object, thereby effectively detecting obstacles.

[0076] In order to efficiently purify the air, in this embodiment, a primary filter 18 and a HEPA high-efficiency filter 19 are sequentially arranged inside the first purifier from top to bottom; a primary filter 1, an electrostatic dust removal module 2, a HEPA high-efficiency filter 3, a first ultraviolet lamp module 4, a photocatalyst filter 5, a second ultraviolet lamp module 6 and a formaldehyde detection device 23 are sequentially arranged inside the second purifier from left to right.

[0077] When the air purifier starts working, the auxiliary purifier first detects the air quality of the whole house, and the detected data results are synchronously transmitted to the main purifier. According to the detected air quality, the whole house is divided into three air quality areas (high-quality area, medium-quality area, and low-quality area). The main purifier first purifies the areas in the house where the air pollution is more serious (i.e., low-quality areas). At the same time, the auxiliary purifier will synchronously turn on the fan blades 16 around the main purifier according to the size of the low-quality air area, and will automatically adjust the air volume when the fan blades 16 are running, so as to accelerate the air circulation around the main purifier. After a period of purification, if the detection device on the main purifier detects that the air quality around it has been significantly improved (formaldehyde concentration ≤1.2mg / m 3 ), the main purifier will move to the next area to purify the air, and so on, purifying the air of the whole house in order from low to high according to the air quality level, and finally improving the air in the whole house.

[0078] The air purifier control method provided in an embodiment of the present invention controls the first purifier to move in the area to be purified according to a pre-planned path upon receiving a preset instruction, and controls the first purifier to purify the air in the area to be purified during the movement, so that the first purifier can comprehensively purify the air in each position in the area to be purified, thereby avoiding the technical problem of poor air purification effect caused by air purification in a small area at a fixed position. Since mobile purification can effectively solve air quality problems in open environments, the technical solution provided in an embodiment of the present invention can effectively purify indoor air in an open environment, thereby greatly meeting user needs and improving user experience.

[0110] To more effectively purify air in an open environment, the air purification system of this embodiment further includes a second purifier wirelessly connected to the first purifier. The first purifier and the second purifier can communicate wirelessly, allowing the first purifier to transmit air quality detection data to the second purifier, which then purifies the air in each unit to be purified in ascending order of air quality.

[0111] In order to facilitate storage and simplify the system structure, such as Figure 3 As shown, the lower part of the second purifier described in this embodiment is provided with a accommodating chamber 8 for accommodating the first purifier; a folding plate 24 is provided at the edge of the bottom plate of the accommodating chamber 8; the folding plate 24 is used for allowing the first purifier to move out of or into the accommodating chamber 8 when unfolded.

[0112] To facilitate charging of the first purifier, the accommodating chamber 8 of this embodiment is provided with charging contacts 10; the first purifier is provided with contact-type charging connectors 9 that match the charging contacts 10. To ensure timely charging of the first purifier, the first purifier of this embodiment is further configured to: upon detecting that the charge level of the first purifier is less than a preset charge threshold, control the first purifier to move to the accommodating chamber 8 and electrically connect the charging connector 9 to the charging contacts 10.

[0113] To accurately detect common pollutants in the air and effectively purify the air, the first and second purifiers of this embodiment are each equipped with formaldehyde detection devices 11, 13, PM2.5 detection devices 12, 14, and an infrared detection device 20. The infrared detection device 20 is used to detect obstacles to prevent collisions between the first and second purifiers during movement.

[0114] In order to efficiently purify the air, in this embodiment, a primary filter 18 and a HEPA high-efficiency filter 19 are sequentially arranged inside the first purifier from top to bottom; a primary filter 1, an electrostatic dust removal module 2, a HEPA high-efficiency filter 3, a first ultraviolet lamp module 4, a photocatalyst filter 5, a second ultraviolet lamp module 6 and a formaldehyde detection device 23 are sequentially arranged inside the second purifier from left to right.

[0115] Wherein, the primary filter 1 is used for preliminary filtering of hair, large particle pollutants, etc. in the air. When the air passes through the electrostatic dust removal module 2, the gas containing dust particles is ionized. At this time, the negatively charged gas ions collide with the dust particles in motion under the action of the electric field force, so that the dust particles are negatively charged and deposited on the anode plate under the action of the electric field force, and the purified gas continues to flow to the next filter unit. The photocatalyst undergoes a photocatalytic reaction under the irradiation of light, producing free hydroxyl radicals and active oxygen with extremely strong oxidizing ability. It has a strong photooxidation-reduction function, can oxidize and decompose various organic compounds and some inorganic substances, and decompose organic pollutants (such as formaldehyde and benzene) into pollution-free water and carbon dioxide. The photocatalyst filter 5 is placed in the middle of the two ultraviolet lamp modules to improve its degradation efficiency under the action of the ultraviolet lamp, ensuring that harmful substances such as formaldehyde and benzene can be completely decomposed. The UV lamp module has a wavelength of 253.7nm. Ultraviolet light in this wavelength band is easily absorbed by the DNA of organisms, changing the DNA structure in the organisms. This allows the UV lamp to effectively disinfect bacteria in the air and perform secondary purification on the air that passes through the photocatalyst filter to ensure that the exhausted air meets the requirements. A moving device 22 is installed at the bottom of the main purifier. When the auxiliary purifier detects that the air quality in a certain area is low, the main purifier can move to the corresponding area to purify the air. Formaldehyde detection devices and PM2.5 detection devices are arranged around the main purifier to detect the air quality around the main purifier.

[0116] The auxiliary purifier 15 measures 30cm x 30cm x 30cm. It features an adjustable top fan 16 for accelerating indoor air circulation. The fan 16 can be adjusted from 0 to 90 degrees to change the direction of air circulation, depending on indoor air quality. The angle of the fan 16 is controlled by a servo 17. The fan 16 can deliver air up to 8 meters, significantly extending the air purifier's purification range. The front housing of the auxiliary purifier incorporates a PM2.5 detector 14 and a formaldehyde detector 13 for monitoring air quality throughout the home. The detected air quality data is then transmitted to the main purifier. A mobile device 21 is mounted on the bottom of the auxiliary purifier, enabling unobstructed air quality monitoring throughout the home. An infrared detector 20 is attached to the auxiliary purifier housing to prevent collisions during monitoring. The auxiliary purifier itself features a small air purification unit for purifying areas with limited air circulation, such as corners and under coffee tables. The auxiliary purifier is composed of a primary filter 18 and a HEPA high efficiency filter 19, and can remove particles with a diameter of 0.3 μm or more in the air at a removal efficiency of over 99.7%.

[0117] The overall structure of the air purification system in this embodiment is shown in FIG. Figure 3As shown. This system is primarily divided into two parts: the main purifier and the auxiliary purifier. The main purifier is divided into upper and lower areas: the lower area is the auxiliary purifier storage area 8, and the upper area is the main purifier purification area 7. From left to right, the main purifier purification area 7 is divided into a primary filter 1, an electrostatic dust removal module 2, a HEPA filter 3, a first UV lamp module 4, a photocatalyst filter 5, a second UV lamp module 6, and a formaldehyde detector 23. 9 and 10 are the charging devices for the auxiliary purifier, with 9 being the charging connector and 10 being the charging contact. 11 and 13 are the first and second formaldehyde detectors, respectively; 12 and 14 are the first and second PM2.5 detectors, respectively; 16 is the auxiliary purifier's circulation blade; 17 is a servo that controls the direction of the circulation blade. 18 and 19 are the primary filter and HEPA filter on the auxiliary purifier, respectively; 21 is the auxiliary purifier's mobile device, and 22 is the main purifier's mobile device; 23 is the third formaldehyde detector.

[0118] The air purifier control method, device, and air purification system provided in the embodiments of the present invention, upon receiving a preset instruction, control the first purifier to move in the area to be purified according to a pre-planned path, and control the first purifier to purify the air in the area to be purified during the movement, so that the first purifier can comprehensively purify the air in each position in the area to be purified, avoiding the technical problem of poor air purification effect caused by air purification of only a small area at a fixed position. Since mobile purification can effectively solve air quality problems in open environments, the technical solution provided in the embodiments of the present invention can effectively purify indoor air in an open environment, thereby greatly meeting user needs and improving user experience.

[0119] The present invention solves the following technical problems:

[0120] 1. Currently, air purifiers can only purify the air in closed small rooms. In an open environment, the air purifier can purify a smaller range of air and the air purification efficiency is low.

[0121] 2. The indoor air circulation is small, and the air quality in different locations in the space is inconsistent. It is necessary to purify key areas where the air quality is poor.

[0122] The present invention has the following beneficial effects:

[0123] The present invention uses a combined air purifier to fully purify the indoor air. The circulation blades on the auxiliary purifier can accelerate the circulation of indoor air, increase the indoor air flow, and thus maximize the purification of the air in various locations in the room. In addition, for some corners in the room, the auxiliary purifier's own purification unit can be used to purify the air within its range. According to the PM2.5 detection device and formaldehyde detection device carried by the auxiliary purifier itself, the main purifier moves to the key areas that need air purification based on the data fed back by the auxiliary purifier.
