Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air purifier and a control method thereof. Background Art

[0002] As essential devices for improving indoor air quality, air purifiers have become essential household appliances and have garnered widespread attention. However, they are often difficult to move and typically must be placed in fixed locations indoors. Consequently, they can only purify a specific area of ​​the room, failing to purify multiple areas, which negatively impacts the user experience. Furthermore, air purifiers offer limited functionality and fail to meet user needs for multi-functionality. Summary of the Invention

[0003] In view of this, the present invention provides an air purifier and a control method thereof to solve the problem that the air purifier can only purify air in a local area of ​​the room and has a relatively single function.

[0004] In a first aspect, the present invention provides an air purifier, comprising:

[0005] The air purification body has the air purification function;

[0006] The robot base has at least a floor cleaning function; the robot base includes driving wheels, which are suitable for carrying the air purification body or moving alone;

[0007] The connecting mechanism is changeable in form, having a locked state for reliably connecting the air purifying body to the robot base, and an unlocked state for enabling the robot base to be separated from the air purifying body; the connecting mechanism includes:

[0008] A robotic arm, the top end of which is fixed to the air purification body and the bottom end of which is detachably clamped to the robot base; the robotic arm comprises:

[0009] A fixed arm, located at the top of the mechanical arm and connected to the air purification body;

[0010] The execution arm is located at the bottom end of the robot arm, and the end of the execution arm away from the fixed arm is provided with a support portion suitable for supporting on a work surface; and when the robot arm is supported on the work surface, the robot arm can form an extended state to lift the air purification body to a height away from the robot base.

[0011] Beneficial effects: The connecting mechanism can reliably fix the air purifier body to the robot base, allowing the air purifier body to move with the robot base, thereby realizing mobile air purification of the air purifier body, facilitating air purification in multiple areas of the room, and increasing the air purification area and purification range; and the robot base has at least a floor cleaning function, which increases the function of the air purifier and meets the multifunctional needs of users. The top of the robotic arm is fixed to the air purifier body, and the bottom of the robotic arm is detachably clamped to the robot base. By adjusting the shape of the robotic arm, the robotic arm can be connected or separated from the robot base, facilitating the combination or separation of the robot base and the air purifier body. The robotic arm includes multiple sections. The first section connected to the air purifier body is a fixed arm, and the last section is an actuator arm. A support portion is provided on the actuator arm. The robotic arm can be supported on the work surface by the support portion. The robotic arm changes shape to form an extended state, so as to lift the air purifier body, facilitate the air purifier body to be separated from the robot base, and facilitate the robot base to move independently for floor cleaning. Compared with the combined state, the floor cleaning efficiency is higher and energy consumption is more saved.

[0012] In the combined state, the robot base serves as the support and mobile base of the air purifier body, supporting the air purifier body. The air purifier body does not need to be equipped with a separate drive wheel. When the robot base moves, it can directly carry the air purifier body with it. In the separated state, the robotic arm serves as the support arm of the air purifier body, supporting the air purifier body at a certain height above the ground, so that the robot base can directly drive under the air purifier body when returning. The deformation of the robotic arm can be controlled to achieve the combination, simplifying the control steps and improving reliability. Moreover, the air purification effect is better after the air purifier body is lifted to a certain height. In addition, after being supported by the robotic arm, the air purifier body is more stable when separated from the robot base, avoiding damage to the components inside the air purifier body due to collision.

[0013] In an optional embodiment, a first connecting structure is provided at the bottom end of the robotic arm, and a second connecting structure is provided on the side wall of the robot base, and the first connecting structure is suitable for being snapped or magnetically attracted to the second connecting structure.

[0014] Beneficial effects: The robotic arm is matched and connected with the second connecting structure on the side wall of the robot base through the first connecting structure at its bottom end, which is convenient for hugging the robot base from all sides, and is not easy to interfere with the air purification body or the robot base, and will not affect the movement of the robot base. Moreover, the connection method is simple, the operation is convenient, and it is convenient to achieve reliable hugging or loosening.

[0015] In an optional embodiment, the first connecting structure includes a clamping block, and the second connecting structure includes a clamping slot, and the robotic arm can be clamped into the clamping slot of the robot base through the clamping block;

[0016] Alternatively, the first connection structure includes a first magnet, the second connection structure includes a second magnet, and the first magnet can be magnetically connected to the second magnet so that the robotic arm holds the robot base tightly.

[0017] Beneficial effect: The mechanical arm on the air purification body is connected to the robot base by a snap-on connection, which is more reliable and not easy to loosen; if the mechanical arm and the robot base are connected by magnetic attraction, the connection or separation is faster and more convenient.

[0018] In an optional embodiment, the robotic arm further includes:

[0019] Connecting arms, at least one of the connecting arms is arranged between the fixed arm and the execution arm, and each of the connecting arms is hinged to the adjacent connecting arm, the adjacent fixed arm and the adjacent execution arm respectively.

[0020] Beneficial effects: At least one connecting arm is set between the fixed arm and the execution arm, and each two adjacent sections of the robotic arm are hinged, which makes it convenient for the robotic arm to bend to separate or connect with the robot base, and convenient to adjust the bending angle of the robotic arm, and convenient to adjust the connection force between the robotic arm and the robot base, and the robotic arm shape adjustment flexibility is higher.

[0021] In an optional embodiment, the air purifier further includes a filter cleaning device, and the filter cleaning device includes:

[0022] The first docking tube is liftably mounted on the robot base; the air purification body includes a filter and a second docking tube arranged in the inner cavity of the air purification body and close to the filter; the first docking tube can be lifted to the second docking tube to dock and connect with it.

[0023] Beneficial effect: The first pair of pipes installed in a liftable manner on the base of the robot can rise to the bottom end of the second pair of pipes in the inner cavity of the air purification body. The first pair of pipes continues to rise to complete the docking connection with the second pair of pipes, making it convenient to provide suction negative pressure to the second pair of pipes through the first pair of pipes.

[0024] In an optional embodiment, the filter cleaning device further includes:

[0025] A bristle assembly is installed at the filter screen and is suitable for performing contact physical cleaning on the filter screen;

[0026] The dust collector head is connected and installed on the second butt joint and is suitable for sucking dust on the filter screen.

[0027] Beneficial effect: The filter cleaning device wipes and cleans the filter through the brush assembly, and the dust collector head is used to suck the dust on the filter. The cleaning effect of the brush and the dust collector head working together is better than the combined effect of the brush cleaning alone and the dust collector head cleaning alone. The reason is that if only the bristles are used, more dust will be generated during the cleaning process. After the bristles stop cleaning, most of the dust will stick to the filter again under the adsorption of gravity and the friction static electricity generated during the cleaning process of the bristles. If only the dust collector head is used to suck dust, the adhesion force between some dust and the filter is greater than the suction force, especially if the dust is not cleaned for a long time, it is not easy to suck out of the filter. If the bristles and the dust collector head work together, the wiping force of the bristles is enough to make the dust on the filter separate from the filter, and then be sucked away by the dust collector head in time, the cleaning efficiency and cleaning effect can be effectively improved, and no dust will be generated, and the user experience is better.

[0028] In an optional embodiment, the robot base includes:

[0029] Cleaning structures;

[0030] The dust collection assembly is connected to the first butt joint and is adapted to be connected to the second butt joint through the first butt joint.

[0031] Beneficial effects: The cleaning structure is used to collect and clean dirt on the ground. The dust collection component can be used as a dust collection component for floor cleaning and a dust collection component for filter cleaning device at the same time, which reduces the number of dust collection components and does not increase the volume of the air purification device; one machine has multiple uses and effectively utilizes the dust collection component.

[0032] In a second aspect, the present invention further provides a control method for an air purifier, applicable to any of the above air purifiers; the control method comprises:

[0033] The control connection mechanism is connected to the robot base, so that the air purification body and the robot base are combined;

[0034] Control the movement of the robot base, turn on the air purifier body, and perform mobile purification;

[0035] Control the connecting mechanism to separate from the robot base, and control the connecting mechanism to support and lift the purification body so that the robot base is separated from the purification body;

[0036] Control the movement of the robot base to clean the floor.

[0037] Beneficial effects: By controlling the connection mechanism, the air purifier body and the robot base can be combined and separated, realizing mobile air purification. The air purifier can be purified in multiple areas indoors without manual transportation. At the same time, the robot base is suitable for cleaning the floor, realizing the multifunctionality of the air purifier, which is convenient for meeting the multifunctional needs of users.

[0038] In a third aspect, the present invention further provides a control method for an air purifier, applicable to any of the above air purifiers; the air purifier further includes an air quality sensor, an obstacle sensor, and a floor cleanliness sensor; the air purifier has a mobile purification mode and a stationary purification mode; the control method comprises:

[0039] Obtaining air quality measurement data and / or obstacle sensor information and / or ground cleanliness status;

[0040] If the air quality exceeds the standard, the air purifier body will be turned on for static purification or the robot base will be controlled to move for mobile purification;

[0041] If the floor cleanliness sensor feedback indicates that the floor needs to be cleaned, the floor cleaning function of the robot base is activated while purifying the air; or, the shape of the connection mechanism is adjusted to separate the air purification body from the robot base, and the robot base is controlled to move to clean the floor;

[0042] In mobile purification mode, if the obstacle sensor reports that an obstacle has been encountered, the moving path will be replanned.

[0043] Beneficial effects: The switch of the air purifier body is controlled according to the air quality, and the static purification mode or the mobile purification mode can be selected according to the air quality conditions; and when the ground needs to be cleaned, the ground cleaning can be carried out in time. When air purification and ground cleaning are required at the same time, the ground cleaning function of the robot base is directly turned on in the mobile purification mode. When cleaning the ground, the air purifier body and the robot base need to be separated, and the robot base moves alone to clean the ground. Since there is no need to carry the air purifier body, the ground cleaning efficiency is higher and energy consumption is saved.

[0044] In a fourth aspect, the present invention further provides a control method for an air purifier, applicable to any of the above air purifiers; the control method comprises:

[0045] Obtain the continuous working time of the air purifier body and compare it with the preset time; if the continuous working time is greater than or equal to the preset time:

[0046] When the air purifier body and the robot base are in the combined state, the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base is started;

[0047] When the air purifier body and the robot base are in a separated state, the robot base is first controlled to return to the bottom of the air purifier body, the shape of the connecting mechanism is adjusted to make the air purifier body and the robot base combined, and then the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base is started.

[0048] Beneficial effect: The continuous working time of the air purifier body is greater than or equal to the preset time, indicating that the filter of the air purifier body needs to be cleaned. When the air purifier body and the robot base are in a combined state, the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base is started to perform immediate cleaning of the filter; when the air purifier body and the robot base are in a separated state, it is necessary to first control the robot base to return to the bottom of the air purifier body, adjust the shape of the connecting mechanism so that the air purifier body and the robot base are combined before cleaning the filter, thereby ensuring that the air purifier can operate stably and reliably.

[0067] The following combination Figures 1 to 7 , describing embodiments of the present invention.

[0068] According to an embodiment of the present invention, on the one hand, Figures 1-6 , provides an air purifier, comprising:

[0069] The air purification body 1 has an air purification function;

[0070] The robot base 2 has at least a floor cleaning function; the robot base 2 includes a driving wheel 21, which is suitable for carrying the air purifier body 1 or moving alone;

[0071] The connecting mechanism 3 is provided on the air purifier body 1 and / or the robot base 2; the shape of the connecting mechanism 3 is changeable, so that the connecting mechanism 3 has a locked state in which the air purifier body 1 and the robot base 2 are reliably connected, and an unlocked separation state in which the robot base 2 can be separated from the air purifier body 1.

[0072] The connecting mechanism 3 can reliably fix the air purifier body 1 to the robot base 2, so that the air purifier body 1 can move with the robot base 2, thereby realizing mobile air purification of the air purifier body 1, facilitating air purification in multiple areas indoors, and increasing the air purification area; and the robot base 2 has at least a floor cleaning function, which increases the function of the air purifier and meets the user's multi-functional needs.

[0073] In this embodiment, the connecting mechanism 3 is provided on the air purifier body 1, and the connecting mechanism 3 can be fastened to or separated from the robot base 2 by changing its form. In some other embodiments, the connecting mechanism 3 can also be provided on the robot base 2, and can be fastened to or separated from the air purifier body 1 by hugging; of course, the connecting mechanism 3 can also include two parts and be provided on the air purifier body 1 and the robot base 2 respectively, and the connection between the two parts can be achieved to realize the connection between the air purifier body 1 and the robot base 2, or a part of the air purifier body 1 is fastened to the robot base 2, and another part of the robot base 2 is fastened to the air purifier body 1.

[0074] It should be noted that, in the combined state, the air purifier body 1 can be placed on the upper surface of the robot base 2 , with the robot base 2 serving as a support seat; or the air purifier body 1 can also be supported on the top or around the robot base 2 by the connecting mechanism 3 .

[0075] In this embodiment, the air purifier body 1 features a compact design, housing a high-efficiency filtration system and fan. A removable filter 11 is attached to the periphery of the air purifier body 1 for easy maintenance. An air outlet is located at the top of the air purifier body 1, and the bottom connects to the robot base 2 via a magnetic or snap-on connection, ensuring a secure connection and easy separation.

[0076] Specifically, the connecting mechanism 3 includes:

[0077] The top end of the robot arm is fixed to the air purification body 1, and the bottom end is detachably clamped to the robot base 2.

[0078] The top end of the robotic arm is fixed to the air purifier body 1, and the bottom end of the robotic arm can be detachably connected to the robot base 2. By adjusting the shape of the robotic arm, the robotic arm and the robot base 2 can be connected or separated, which facilitates the combination or separation of the robot base 2 and the air purifier body 1.

[0079] In some embodiments, as Figure 4 and Figure 5 As shown, the robotic arm includes:

[0080] The fixed arm 32 is located at the top of the mechanical arm and is connected to the air purification body 1;

[0081] The execution arm 31 is located at the bottom end of the robot arm. The end of the execution arm 31 away from the fixed arm 32 is provided with a support portion suitable for supporting on the working surface; and when the robot arm is supported on the working surface, the robot arm can form an extended state to lift the air purification body 1 to a height away from the robot base 2.

[0082] The robotic arm includes multiple sections. The first section connected to the air purification body 1 is a fixed arm 32, and the last section is an execution arm 31. A support portion is provided on the execution arm 31. The robotic arm can be supported on the working surface by the support portion. The shape of the robotic arm changes to form an extended state, so as to lift the air purification body 1 and separate the air purification body 1 from the robot base 2, making it easier for the robot base 2 to move alone for floor cleaning. Compared with the combined state, the floor cleaning efficiency is higher and more energy-saving. In the combined state, the robot base 2 serves as the support and mobile base of the air purification body 1, supporting the air purification body 1. The air purification body 1 does not need to be provided with a separate drive wheel. When the robot base 2 moves, it can directly carry the air purification body 1 to move, simplifying the structure. In the split state, the robotic arm serves as the support arm of the air purifier body 1, supporting the air purifier body 1 at a certain height away from the ground, so that the robot base 2 can directly drive to the bottom of the air purifier body 1 when returning. At this time, the robotic arm can be controlled to deform and achieve fusion, which simplifies the control steps and improves reliability. Moreover, the air purification effect will be better when the air purifier body 1 is lifted to a certain height and then purifies statically. In addition, after being supported by the robotic arm, the air purifier body 1 is more stable when separated from the robot base 2, avoiding damage to the devices in the air purifier body 1 due to collision.

[0083] In some other embodiments, one end of the robotic arm can also be fixed on the robot base 2, and then the air purifier body 1 can be tightly embraced by the bending arm of the robotic arm, so that the robot base 2 can carry the air purifier body 1 to move.

[0084] In some embodiments, a first connection structure is provided at the bottom end of the robotic arm, and a second connection structure is provided on the side wall of the robot base 2 . The first connection structure is suitable for being snapped or magnetically attracted to the second connection structure.

[0085] The robotic arm is matched and connected with the second connecting structure on the side wall of the robot base 2 through the first connecting structure at its bottom end, which is convenient for hugging the robot base 2 from all sides, and is not easy to interfere with the air purification body 1 or the robot base 2, and will not affect the movement of the robot base 2. Moreover, the connection method is simple, the operation is convenient, and it is convenient to achieve reliable hugging or loosening.

[0086] Specifically, in some embodiments, the first connection structure includes a card block, and the second connection structure includes a card slot. The robotic arm can be connected to the card slot of the robot base 2 through the card block to achieve a reliable connection.

[0087] The mechanical arm on the air purification body 1 is connected to the robot base 2 by a snap-fit ​​method, which is more reliable and not easy to loosen.

[0088] In some embodiments, the first connection structure includes a first magnet, and the second connection structure includes a second magnet. The first magnet can be magnetically connected to the second magnet to enable the robotic arm to hold the robot base 2. If the robotic arm and the robot base 2 are connected by magnetic attraction, connection and separation are faster and more convenient.

[0089] Specifically, the support portion includes a chuck, which is used to clamp the robot base 2 in the assembled state, and is supported on the working surface (ground) in the separated state to improve support stability.

[0090] In some embodiments, the robotic arm further comprises:

[0091] At least one connecting arm 33 is disposed between the fixed arm 32 and the actuator arm 31, and each connecting arm 33 is articulated with an adjacent connecting arm 33, an adjacent fixed arm 32, and an adjacent actuator arm 31. Motors 34 are provided at the nodes to drive the connecting arm 33 or the actuator arm 31 to rotate, enabling adjustment and transformation of the robot arm's configuration.

[0092] At least one connecting arm 33 is set between the fixed arm 32 and the execution arm 31, and each two adjacent sections of the robotic arm are hinged, which makes it convenient for the robotic arm to adjust its shape and bending angle to achieve separation or connection with the robot base 2. In addition, adjusting the bending angle of the robotic arm can also adjust the connection force between the robotic arm and the robot base 2. The hinged connection between the sections makes the robotic arm shape adjustment more flexible.

[0093] like Figure 1As shown in the figure, the shape of the robot arm when the air purifier body 1 and the robot base 2 are combined is given. The robot arm adjusts the angle of the robot arm by rotating each joint, and finally becomes vertical, lifting the air purifier body 1 to a certain height, so that the air purifier body 1 and the robot base 2 are completely separated, forming Figure 2 The robot base 2 can then be moved to another location to perform floor cleaning. Once the work is complete, the robot base 2 returns to the bottom of the air purifier body 1. The robotic arm begins adjusting its angle, lowering the air purifier body 1 until it rests completely on the robot base 2. The robotic arm further contracts and deforms, eventually embracing the robot base 2, tightening the two together.

[0094] In some embodiments, the air purifier further includes a filter cleaning device (not shown in the figure), which includes:

[0095] The first docking tube is liftably mounted on the robot base 2; the air purifier body 1 includes a filter 11 and a second docking tube arranged in the inner cavity of the air purifier body 1 and close to the filter 11; the first docking tube can be lifted to the second docking tube and docked with it.

[0096] The first docking tube installed in a liftable manner on the robot base 2 can rise to the bottom end of the second docking tube in the inner cavity of the air purification body 1. When the first docking tube continues to rise, it completes the docking connection with the second docking tube, making it convenient to provide suction negative pressure to the second docking tube through the first docking tube.

[0097] It should be noted that the first docking tube is a retractable tube, the bottom end of which is mounted and docked to the docking port 22 of the robot base 2. The lifting mechanism is in transmission connection with the first docking tube to drive the first docking tube to extend and elevate. The lifting mechanism can be a telescopic rod, a gear lifting mechanism, a screw lifting mechanism, or other lifting mechanisms known in the relevant art. Furthermore, the first docking tube and the lifting mechanism can also be disposed within the inner cavity of the robot base 2, with a through hole defined in the robot base 2, through which the first docking tube can pass to connect with the second docking tube.

[0098] In some embodiments, the filter cleaning device further comprises:

[0099] The bristle assembly is installed at the filter 11 and is suitable for performing contact physical cleaning on the filter 11;

[0100] The dust collector head is connected and installed on the second butt joint and is suitable for sucking dust on the filter screen 11 .

[0101] The filter cleaning device wipes and cleans the filter 11 through a brush assembly, and the dust collector head is used to suck the dust on the filter 11. The cleaning effect of the bristles of the brush assembly and the dust collector head working together is better than the combined effect of the bristles cleaning alone and the dust collector head cleaning alone; the reason is that when only the bristles are used, more dust will be generated during the cleaning process. After the bristles stop cleaning, most of the dust will stick to the filter 11 again under the adsorption effect of gravity and the friction static generated during the cleaning process of the bristles. When the dust is only sucked by the dust collector head, the adhesion force between some dust and the filter 11 is greater than the suction force, especially when the dust is not cleaned for a long time, it is not easy to suck out of the filter 11. When the bristles and the dust collector head work together, the wiping force of the bristles is enough to make the dust on the filter 11 separate from the filter 11, and then be sucked away by the dust collector head in time, the cleaning efficiency and cleaning effect are effectively improved, and no dust will be generated, and the user experience is better.

[0102] Among them, in some embodiments, the bristle assembly includes bristles, the bristles and the dust collector head can be designed as an integral whole, the bristles can be set on the dust collector head, multiple bristles can be set, and multiple bristles and multiple dust collection holes can be alternately distributed on the dust collector head at intervals, and the dust collector head is installed on the second docking tube. While simplifying the structure, the bristles and dust collection holes are both set on the dust collector head, which can improve the cleaning effect, and can be driven by the same driving mechanism.

[0103] In other embodiments, the bristle assembly includes bristles and a driving member, and the driving member drives the bristles to move back and forth along a set direction to clean the filter 11.

[0104] In some embodiments, the robot base 2 includes:

[0105] Cleaning structures;

[0106] The dust collection assembly is connected to the first butt joint and is adapted to be connected to the second butt joint through the first butt joint.

[0107] The cleaning structure is used to collect and clean dirt on the ground. The dust collection component can be used as a dust collection component for floor cleaning and a dust collection component for filter cleaning device at the same time, which reduces the number of dust collection components and does not increase the volume of the air purification device. One machine has multiple uses and effectively utilizes the dust collection component.

[0108] In this embodiment, the robot base 2 includes:

[0109] The driving module, consisting of a driving motor and driving wheels 21, enables the robot to move freely indoors;

[0110] The lifting mechanism, when the robot base 2 is stationary, can lift the robot base 2, so that the filter cleaning device enters the inner cavity of the air purification body 1 to clean the filter 11;

[0111] The filter cleaning device, including a brush and a vacuum cleaner, can effectively clean the dust and impurities on the surface of the filter 11;

[0112] The floor cleaning module includes a vacuum cleaner and a mop, and can perform vacuuming and mopping operations on the floor;

[0113] Sensor components, including air quality sensors, obstacle sensors, and ground sensors, are used to perceive environmental information in real time and feed it back to the control module.

[0114] like Figure 6 As shown, the robot base 2 includes a body, a dust collection box 23 installed on the body and a docking port 22 on the top surface of the body. A radar 24 is also provided on the upper part of the side wall of the body.

[0115] According to an embodiment of the present invention, on the other hand, Figure 7 As shown, a control method for an air purifier is also provided, which is applicable to the above-mentioned air purifier; the control method includes:

[0116] The control connection mechanism 3 is connected to the robot base 2, so that the air purification body 1 and the robot base 2 are combined;

[0117] Control the robot base 2 to move, turn on the air purification body 1, and perform mobile purification;

[0118] Control the connecting mechanism 3 to separate from the robot base 2, and control the connecting mechanism 3 to support and lift the purification body so that the robot base 2 is separated from the purification body;

[0119] Control the robot base 2 to move and clean the floor.

[0120] By controlling the connecting mechanism 3, the air purifier body 1 and the robot base 2 can be combined and separated, thereby realizing mobile air purification. The air purifier can be purified in multiple areas of the room without manual transportation. At the same time, the robot base 2 is suitable for cleaning the floor, realizing the multifunctionality of the air purifier, which is convenient for meeting the multifunctional needs of users.

[0121] It should be noted that when the air purifier body 1 separates from the robot base 2 and then returns, the position of the robot base 2 can be determined by visual sensors and / or infrared sensors. After it is determined that the combination conditions are met (reaching directly below), the robotic arm can be controlled to deform, the air purifier body 1 slowly descends, and the robot base again supports the weight of the air purifier body 1, and then the robotic arm is used to tighten the robot base 2 to achieve reliable connection and fixation between the two.

[0122] According to an embodiment of the present invention, on the other hand, a control method for an air purifier is provided, which is applicable to any of the above air purifiers; the air purifier further includes an air quality sensor, an obstacle sensor, and a floor cleanliness sensor; the air purifier has a mobile purification mode and a stationary purification mode; the control method includes:

[0123] Obtain air quality measurement data, obstacle sensor information, and ground cleanliness status;

[0124] If the air quality exceeds the standard, the air purification body 1 is turned on for static purification or the robot base 2 is controlled to move for mobile purification;

[0125] If the floor cleanliness sensor feedback indicates that the floor needs to be cleaned, the floor cleaning function of the robot base 2 is activated while purifying the air; or, the shape of the connecting mechanism 3 is adjusted to separate the air purification body 1 from the robot base 2, and the robot base 2 is controlled to move to clean the floor;

[0126] In mobile purification mode, if the obstacle sensor reports that an obstacle has been encountered, the moving path will be replanned.

[0127] The switch of the air purifier body 1 is controlled according to the air quality, and the static purification mode or the mobile purification mode can be selected according to the air quality conditions; and when the ground needs to be cleaned, the ground cleaning can be carried out in time. When air purification and ground cleaning are required at the same time, the ground cleaning function of the robot base 2 is directly turned on in the mobile purification mode. When cleaning the ground, the air purifier body 1 and the robot base 2 need to be separated, and the robot base 2 moves alone to clean the ground. Since there is no need to carry the air purifier body 1, the ground cleaning efficiency is higher and energy consumption is saved.

[0128] In some embodiments, it is also possible to obtain only air quality measurement data or obstacle sensor information or ground cleanliness status as needed; and then adjust the shape of the connecting mechanism 3 as needed to realize the combination or separation of the air purification body 1 and the robot base 2 to perform mobile air purification, static air purification or ground cleaning.

[0129] It should be noted that air quality sensors primarily detect particulate matter, gases, and comprehensive parameters in the air. Particle sensors can be optical sensors, which detect concentrations of particles like PM2.5 and PM10 using the principle of light scattering, offering high precision and rapid response. Particle sensors can also be infrared or laser sensors. Laser sensors utilize laser scattering technology to monitor PM2.5 and PM10 in real time.

[0130] The gas sensor can be an optical gas sensor, which can detect the concentration of gases such as oxygen, carbon dioxide, and formaldehyde based on the principle of spectral absorption.

[0131] Sensor selection needs to be combined with actual needs, and the home environment focuses on PM2.5 and formaldehyde detection.

[0132] Obstacle sensors can include infrared sensors, which transmit and receive infrared light to detect obstacles or material differences on the floor. For example, they can identify the transition between carpet and hard flooring and adjust the cleaning mode accordingly. They can also include visual sensors, equipped with cameras and image processing algorithms, to identify stains, residue, or debris distribution on the floor, and determine cleaning needs through real-time image analysis. Floor material identification (e.g., tile, wood flooring, carpet) can be achieved through capacitance, resistance, or optics, automatically adjusting suction power or brush head speed to optimize cleaning results. Obstacle sensors can also include ultrasonic sensors, which use ultrasonic reflections to determine the distance between the floor and obstacles, assisting in building a cleaning path and avoiding repeated cleaning of already cleaned areas. Obstacle sensors can also include physical contact sensors, located on the edge of the robot base 2. These sensors trigger collision signals to force a change in direction to prevent the robot from getting stuck. Furthermore, they can include anti-fall sensors, which detect floor height differences (e.g., the edge of a staircase) and use infrared or ultrasonic signals to prevent the robot from falling.

[0133] Floor cleaning sensors include gyroscopes and accelerometers, which monitor the robot's motion trajectory and posture to ensure complete cleaning coverage and indirectly reflect the floor cleaning status. They can also include acoustic wave sensors, which detect floor dust concentration through acoustic waves and dynamically adjust the cleaning intensity.

[0134] The Robot Base 2 can also adopt a multi-sensor fusion solution, such as combining lidar to build maps, infrared sensors to avoid obstacles, and visual sensors to identify stains, to achieve more accurate cleaning status judgment.

[0135] According to an embodiment of the present invention, in another aspect, a control method for an air purifier is provided, which is applicable to any of the above air purifiers; the control method comprises:

[0136] Obtain the continuous working time of the air purifier body 1 and compare it with the preset time; if the continuous working time is greater than or equal to the preset time:

[0137] When the air purifier body 1 and the robot base 2 are in the combined state, the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base 2 is started;

[0138] When the air purifier body 1 and the robot base 2 are in a separated state, the robot base 2 is first controlled to return to the bottom of the air purifier body 1, and the shape of the connecting mechanism 3 is adjusted to make the air purifier body 1 and the robot base 2 combined. Then, the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base 2 is started.

[0139] The continuous working time of the air purifier body 1 is greater than or equal to the preset time, indicating that the filter 11 of the air purifier body 1 needs to be cleaned. When the air purifier body 1 and the robot base 2 are in a combined state, the first docking pipe of the filter cleaning device is controlled to rise to the second docking pipe to complete the docking, and the dust collection component and / or brush component of the robot base 2 are started to perform immediate cleaning of the filter 11; when the air purifier body 1 and the robot base 2 are in a separated state, it is necessary to first control the robot base 2 to return to the bottom of the air purifier body 1, adjust the shape of the connecting mechanism 3 so that the air purifier body 1 and the robot base 2 are combined before cleaning the filter 11, thereby ensuring that the air purifier can operate stably and reliably.

[0140] A control method for an air purifier according to an embodiment of the present invention includes the following process.

[0141] Sensor data collection: Air quality sensors monitor indoor air quality in real time, obstacle sensors detect obstacles in the moving path, and floor cleanliness sensors detect floor conditions. When an area with poor air quality is detected, the vehicle will stay in that area for a long time to continuously purify the air. When encountering obstacles during movement, the vehicle will detour and then return to the planned path to continue moving. The vehicle will pass through clean areas and clean dirty areas back and forth multiple times. The above can rely on the visual system to incorporate home floor conditions into the training plan.

[0142] Path Planning: Based on sensor data, the control module plans the robot's movement path, ensuring it covers the maximum area and avoids obstacles. After a period of use, the device memorizes all indoor paths and plans the optimal path. Subsequently, the robot base 2 can operate according to its memorized path.

[0143] Filter cleaning trigger: When the robot base 2 is stationary (during air purification, polluted air outside the filter is drawn into the filter for filtration. Filter self-cleaning removes pollutants from the filter surface, causing air to flow outward; the two are exactly opposite. If the air purifier is operating while the filter cleaning is activated, it will cause mutual interference and make it difficult to achieve the desired cleaning effect), the control module activates the lifting mechanism, lifting the first connecting pipe of the filter cleaning device into the inner cavity of the air purifier body 1 to clean the filter 11. Users can set the cleaning cycle of the filter 11 according to seasonal and environmental factors.

[0144] Floor Cleaning Mode Switching: When the robot base 2 is separated from the air purifier body 1, the control module switches to floor cleaning mode. The drive module and floor cleaning module work together to vacuum and mop the floor. During this process, the robot base 2 activates navigation mode and moves to other locations on its own.

[0145] Linkage with smart home: Through Wi-Fi or Bluetooth modules, the air purifier can be linked with other smart home devices (such as air conditioners, smart door locks, etc.) to further enhance the user experience.

[0146] Through the above design, the intelligent mobile air purifier of the present invention not only achieves efficient and intelligent air purification, but also can clean the floor through the detachable base, meeting users' demand for multifunctional smart home devices. At the same time, the addition of automatic filter cleaning function significantly reduces users' maintenance costs and improves the overall competitiveness of the product.

[0147] The present invention successfully solves the problems of single function, low purification efficiency, and difficulty in cleaning the filter of existing air purifiers through the design of the robot base 2 and the intelligent control method, and has broad market prospects and practical application value.

[0148] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
