Description

Technical Field

[0001] This invention relates to the field of intelligent control technology, specifically to a pet air purifier, a control method, and a storage medium. Background Technology

[0002] With the continuous rise in pet ownership rates among urban households, indoor air pollution caused by pets is becoming increasingly prominent, making air purifiers a necessity for pet-owning families. However, existing air purifiers, in pursuit of aesthetics and efficiency, are designed with smooth, enclosed, and inaccessible casings, typically placed in room corners. While this design is reasonable for human users, it presents several challenges for pets sharing the same space. For example, pets (such as felines) have a natural need to scratch, sharpen their claws, and climb vertical surfaces, a need that is precisely suppressed by the smooth, enclosed casing of the purifier. Especially when pets scratch the purifier casing, it can easily cause scratches, blockage of the air intake, damage to sensors, or even the device tipping over, leading to safety accidents. Summary of the Invention

[0003] This invention provides a pet air purifier, a control method, and a storage medium to address the shortcomings of existing air purifiers, such as conflicting needs between humans and pets and limited perception of pet behavior, which prevent true integration between pets and devices and seriously affect device control efficiency and safety.

[0004] In a first aspect, the present invention provides a pet air purifier, which includes a purifier body and a control module disposed inside the purifier body; the pet air purifier further includes: Interactive kit, which is set on the outer surface of the air purifier body, is used to provide an interactive area for pets to interact with the air purifier body; The sensing module is located inside the purifier body and its position corresponds to that of the interactive kit. It is used to collect multimodal sensing signals generated by the interactive kit when the pet interacts in the interactive area, and then send the multimodal sensing signals to the control module. The control module is connected to the sensing module and is used to identify the pet's behavior type based on the received multimodal sensing signals, and control the operation of the pet air purifier according to the pet's behavior type. The interactive kit has a layered composite structure, which includes an inner support layer, a middle buffer layer and a surface woven layer in sequence along the direction away from the purifier body. The middle buffer layer is used to buffer the impact of interaction and protect the internal sensors. The inner support layer is used to ensure the overall rigidity of the interactive kit. The interactive kit is detachably connected to the purifier body through the inner support layer.

[0005] This invention relates to a pet air purifier. By incorporating an interactive kit on the outer surface of the purifier body, it provides a dedicated interaction area for pets. This guides natural behaviors such as scratching and clawing that would normally occur on the purifier's outer shell to the interactive kit surface, fundamentally preventing direct damage to the purifier's outer shell. This resolves the conflict between the smooth, enclosed outer shell of existing purifiers and the behavioral needs of pets, achieving a harmony between human and pet needs. Simultaneously, a sensing module is placed on the inner side of the purifier body, corresponding to the interactive kit. By collecting multimodal sensor signals generated when the pet interacts with the kit, it provides reliable support for the control module to accurately identify different behavior types. This enables refined pet behavior recognition and differentiated control of the device, significantly improving the device's intelligence and user experience. Furthermore, the layered composite interactive kit of this invention features three layers that each perform their specific functions and work in concert. The outer woven layer directly supports pets' scratching and clawing behaviors, catering to their natural interactive needs. The middle buffer layer cushions the impact of pet interactions, optimizing the tactile experience of scratching and slapping while reducing the impact on the internal sensing module, protecting sensor components and ensuring sensor accuracy and the lifespan of the purifier. The inner support layer provides structural rigidity for the entire interactive kit, preventing deformation under stress and ensuring installation stability and structural durability. The inner support layer also enables a detachable connection to the purifier body. When the interactive kit becomes worn or aged due to long-term pet scratching, it can be disassembled and replaced separately without replacing the entire purifier or its casing, significantly reducing long-term maintenance costs. The detachable structure also facilitates the removal of residual pet hair, dander, and other dirt from the cleaning kit, improving ease of use.

[0006] In one alternative implementation, the surface woven layer includes: a rough textured region and a plurality of elastic mesh regions; The rough textured area is for pets to sharpen their claws; the flexible mesh area deforms in response to the pet's interactions, providing tactile feedback.

[0007] In this invention, the functional division of the rough texture area and the elastic mesh area is adapted to different interactive behaviors of pets. The rough texture area serves as the main functional area, which meets the pet's high-frequency scratching needs and satisfies the pet's natural scratching instinct. The elastic mesh area can provide tactile feedback through deformation, which can meet the pet's interactive needs of stretching upwards and tentatively scratching. This covers the diverse behavioral scenarios of pets and is more in line with the behavioral characteristics of pets than a single surface structure.

[0008] In one alternative implementation, the sensing module includes multiple vibration sensors, multiple pressure sensors, and multiple capacitive touch sensors. Among them, vibration sensors, pressure sensors and capacitive touch sensors are arranged in a cyclical pattern along the circumference of the purifier body, and the arrangement height of each type of sensor corresponds to the coverage height range of the interactive kit. Each vibration sensor is used to collect vibration signals received by the interactive kit when the pet interacts in the interactive area; Each pressure sensor is used to collect pressure signals from the interactive kit when the pet interacts with the interactive area; Each capacitive touch sensor is used to collect the capacitive signals generated by the interactive kit when the pet interacts with the interactive area.

[0009] This invention uses three types of sensors—vibration, pressure, and capacitance—to collect interaction signals from different physical dimensions. The complementary features of these multiple signal types allow for cross-verification, overcoming the limitations of a single sensor. It can not only determine whether a pet is engaging in interactive behavior, but also accurately distinguish between different behavior types such as scratching, climbing, rubbing, and patting, significantly reducing the false judgment rate and providing a reliable data foundation for the differentiated intelligent control of air purifiers.

[0010] In one optional implementation, the pet air purifier further includes an interactive feedback component; the interactive feedback component is disposed on the purifier body and connected to the control module, and is used to generate corresponding interactive feedback signals based on the control commands output by the control module to guide the pet's behavior.

[0011] This invention also includes an interactive feedback component designed to complement the behavior recognition capabilities of the sensing and control modules. Specifically, it outputs corresponding feedback signals for the pet's interactive behavior in the interactive area, guiding and reinforcing the pet's scratching and activity habits in the designated area, reducing the pet's scratching and damage to other furniture or air purifiers in the room, and consolidating the design effect of human-pet harmony from a behavioral perspective.

[0012] In one optional implementation, the top of the purifier body is also provided with an air outlet, and an air guide plate connected to the control module is provided at the air outlet to adjust the air outlet direction and change the airflow organization direction. The interactive feedback component includes an LED light strip located at the edge of the air vent. The control module generates control commands based on the identified pet behavior type to control the LED light strip to emit colors and / or light effects corresponding to the pet behavior type, providing visual feedback signals to the pet and guiding the pet to focus on the interactive kit surface to perform corresponding behavioral interactions.

[0013] This invention also incorporates an air guide plate at the air outlet and an LED light strip along the edge of the air outlet. The adjustable air guide plate changes the airflow direction, dynamically adjusting the airflow organization to match the pollution characteristics of different pet behaviors. For example, it actively guides fiber debris from scratching and hair shed from grooming to the air inlet, achieving targeted capture of pollution sources. This allows the air purification function to dynamically link with pet behavior, significantly improving purification efficiency and accuracy, overcoming the limitations of traditional fixed-direction air purifiers that passively purify. Furthermore, placing the LED light strip at the edge of the air outlet ensures that, when the pet is active in the interactive area below, its line of sight is clearly upward, allowing it to clearly capture the light signal. This strong visual feedback ensures effective behavioral guidance. Additionally, the light strip is located away from the high-frequency scratching area in the lower part of the device, preventing direct damage to the light strip components from pet scratching or external impacts. It is also less likely to be blocked by the pet's body, ensuring a consistently clear feedback signal.

[0014] In a second aspect, the present invention provides a control method for a pet air purifier, applicable to a pet air purifier according to the first aspect above or any corresponding embodiment thereof, the method comprising: Acquire multimodal sensor signals generated by the interactive kit when the pet interacts with it; Identifying pet behavior types based on multimodal sensor signals; Control the operation of the pet air purifier according to the pet's behavior type.

[0015] The control method of the pet air purifier of the present invention can accurately distinguish different pet behavior types such as scratching, climbing, rubbing, and patting by acquiring multimodal sensor signals generated by the pet on the interactive kit. This overcomes the shortcomings of the prior art, which can only determine whether the pet is present or its general posture, and provides a reliable decision basis for differentiated control. At the same time, the operation of the pet air purifier is controlled according to the identified pet behavior type, so that the purifier can respond to different behaviors. This realizes the leap from "passively avoiding pets" to "actively responding to behaviors", and improves the depth of interaction and intelligence level between the device and the pet.

[0016] In one optional implementation, the multimodal sensing signals include vibration signals, pressure signals, and capacitance signals; identifying pet behavior types based on the multimodal sensing signals includes: Within a preset time period, when the vibration signal exhibits periodic high-frequency impact characteristics, the pet's contact area on the interactive kit is concentrated and its position is stable based on the pressure signal, and the pet's contact range on the interactive kit is less than a preset threshold and its position is fixed based on the capacitance signal, the pet's behavior type is determined to be scratching behavior. Within a preset time period, when the vibration signal has no periodic high-frequency impact characteristics, the pressure center of the pet's contact area on the interactive kit is continuously displaced along a preset direction based on the pressure signal, and the contact range of the pet on the interactive kit is greater than a preset threshold and a unidirectional displacement occurs along a preset direction based on the capacitance signal, the pet's behavior type is determined to be climbing behavior. Within a preset time period, when the vibration signal shows low-frequency continuous small fluctuations, the contact area of ​​the pet on the interactive kit is diffusely distributed based on the pressure signal, and the contact range of the pet on the interactive kit is greater than a preset threshold based on the capacitance signal, the pet behavior type is determined to be rubbing behavior. Within a preset time period, when the vibration signal exhibits the characteristics of a single instantaneous impact and the pressure signal exhibits the characteristics of an instantaneous spike, the pet's behavior type is determined to be slapping behavior.

[0017] This invention overcomes the limitations of single-sensor recognition by using three different physical dimensions of sensing signals—vibration, pressure, and capacitance—to complement and jointly determine the behavior. Specifically, vibration signals capture the temporal dynamic characteristics of the action, while pressure and capacitance signals reconstruct the spatial distribution and positional change characteristics of the contact. The cross-verification of these multi-dimensional features can effectively eliminate external interference such as environmental vibration and accidental contact, significantly reducing the probability of misjudgment and missed judgment, and ensuring the reliability of pet behavior recognition.

[0018] In one alternative implementation, controlling the operation of the pet air purifier based on the pet's behavior type includes: When the pet's behavior is scratching, reduce the speed of the pet air purifier's fan. When the pet's behavior is climbing, control the pet air purifier's fan to maintain the current speed. When the pet is rubbing its fur, the fan of the pet air purifier will be turned up to the highest speed. When the pet's behavior is slapping, the fan of the pet air purifier will be kept running at its current speed.

[0019] This invention matches corresponding wind speeds to the pollution characteristics and interaction states of different behaviors. For example, pet rubbing produces a large amount of loose hair, dander, and odors, which is a high-pollution scenario. Increasing the wind speed to the highest level can quickly capture pollutants and purify the air to ensure purification efficiency. Scratching produces less pollution and the pet is in a state of continuous focused close interaction. Running the wind speed at a lower speed can reduce equipment noise and avoid disturbing the pet. Climbing and patting are momentary exploratory behaviors. Maintaining the current wind speed can ensure a stable purification rhythm. The above-mentioned fan speed adjustment scheme based on pet behavior types achieves dynamic adaptation between purification intensity and scenario requirements, which helps to improve the balance between purification efficiency and pet-friendly experience.

[0020] In one optional embodiment, the pet air purifier further includes an air outlet on the top of the purifier body, an air guide plate at the air outlet, and / or an interactive feedback component, wherein the interactive feedback component is an LED light strip; the method further includes: When the pet's behavior is scratching, control the air deflector to tilt downwards to create a circulating airflow, and / or control the LED light strip to display a blue-green light effect; When the pet's behavior is climbing, control the LED light strip to display a dynamic yellow-green gradient light effect; When the pet's behavior is rubbing against its fur, control the air deflector to direct the airflow to the contact area, and / or control the LED light strip to emit a green light effect; When the pet's behavior is patting, the LED strip will flash blue-purple light, and the pet air purifier will output a prompt sound to guide the interaction.

[0021] This invention also designs a scheme based on pet behavior type linkage to control airflow of the air guide plate and multi-sensory interactive feedback. It synchronously binds air purification optimization (i.e., airflow control of the air guide plate) and pet behavior guidance (i.e., LED light effects and prompt sound feedback) to behavior recognition logic. In the same scenario, it achieves the dual goals of "precise pollution treatment" and "positive guidance of pets", breaking through the limitation of traditional air purifiers that can only achieve a single purification function. This allows the device to take into account the core value of air governance and human-pet harmony.

[0022] In one optional implementation, the control method for the pet air purifier further includes: When the pet behavior types identified by multimodal sensor signals are inconsistent, the judgment is made according to the priority order of scratching behavior, climbing behavior, rubbing behavior, and patting behavior, and the pet behavior type with the highest priority is taken as the final pet behavior type.

[0023] In the event of a conflict in multimodal identification, this invention also designs a corresponding decision scheme based on behavior priority. Specifically, it outputs a unique behavior type result through a decision rule with fixed priority, which solves the problem of decision conflict and logical contradiction that easily occurs in multimodal joint identification from a mechanism perspective. It avoids confusion in control logic such as fan speed regulation, air guide plate adjustment, and interactive feedback due to non-unique results, and ensures the stability and reliability of the entire identification and control system.

[0024] In one optional implementation, the control method for the pet air purifier further includes: The total duration of the claw-grinding behavior is recorded cumulatively. When the total trigger time reaches the preset maintenance time threshold, control the pet air purifier to remind users to replace the interactive kit.

[0025] This invention also takes into account the damage caused by pets' scratching behavior to the interactive kit. By accumulating the total duration of scratching behavior, the wear and tear of the kit can be measured, which can provide early warning of wear and tear, thereby extending the service life of the whole machine and the sensing components and greatly reducing maintenance costs.

[0026] Thirdly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to execute the control method for a pet air purifier according to the second aspect or any corresponding embodiment described above. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the numerous problems with pet air purifiers, current technologies install pet-friendly functions as add-ons on the outside of the purifier. However, in these solutions, the purifier's casing remains a sealed surface that needs protection, and the fundamental conflict between human and pet needs remains unchanged. Furthermore, existing technologies also employ avoidance-based intelligent control, which uses position sensors to detect the distance between the pet and the purifier, automatically reducing the fan speed when the pet approaches to avoid startling it with noise. However, in this type of solution, the purifier and pet maintain a relationship of avoiding contact rather than actively interacting.

[0032] In summary, current air purifiers, when used in pet-owning scenarios, merely add external pet accessories without altering the "untouchable" nature of the outer casing. Pets' scratching and clawing behaviors are consistently viewed as destructive factors requiring prevention, rather than behavioral needs that can be guided and satisfied. This prevents the appliance from coexisting with pet behavior, making it difficult to avoid destructive actions by pets. Furthermore, current technology cannot distinguish specific types of pet behavior on the device's surface, resulting in a limited sensory dimension and hindering precise control of the device.

[0033] Based on this, this embodiment proposes an air purifier solution aimed at solving the following technical problems: 1. Conflict between human and pet needs: Existing purifiers are designed with a smooth, enclosed, protected outer shell, which contradicts the natural need of pets to scratch and sharpen their claws, making destructive behavior by pets difficult to avoid. 2. Lack of behavioral perception: Existing solutions can only determine whether a pet is present, but cannot identify the specific type of behavior acting on the device surface. 3. Lack of interactive feedback: Existing purifiers lack meaningful two-way interaction with pets; the device is more of an indifferent machine to pets, unable to guide pet behavior towards a path that is harmless to the device. 4. Maintenance cost issues: Once the outer shell is scratched, it affects the overall aesthetics and functionality of the machine, resulting in high maintenance costs and a short lifespan. Specifically, the main technologies of the above solution include: 1. Replaceable interactive kit structure: A detachable interactive kit is set on the outer surface of the purifier body, with a rough textured area for pets to sharpen their claws and an elastic mesh area for scratching; this structure transforms the pet's natural behavior from damaging the outer shell to using consumables, fundamentally resolving the conflict between human and pet needs. 2. Multimodal Behavior Perception System: Multiple vibration sensors, pressure sensors, and capacitive touch sensors are arranged inside the air purifier. Through the collaborative analysis of these three types of sensor signals, and using behavior category logic and decision rules based on necessary feature conditions, it can accurately distinguish specific behaviors such as scratching, climbing, rubbing, and patting. 3. Differentiated Control and Positive Feedback: Based on the identified behavior type, the air purifier automatically switches its operating mode and provides positive feedback to the pet's behavior through changes in airflow direction, dynamic light colors, and soothing sounds, guiding the pet to focus its scratching behavior on the interactive surface.

[0034] This embodiment provides a pet air purifier. Figure 1 This is a structural block diagram of a pet air purifier according to an embodiment of the present invention. Figure 1 As shown, the pet air purifier includes a purifier body 1 and a control module 2 disposed inside the purifier body 1; the pet air purifier also includes an interaction kit 3 and a sensing module 4. The interaction kit 3 is disposed on the outer surface of the purifier body 1, providing an interaction area for the pet to interact with the purifier body 1; the sensing module 4 is disposed on the inner side of the purifier body 1, and its position corresponds to that of the interaction kit 3. It is used to collect multimodal sensing signals generated by the interaction kit 3 when the pet interacts in the interaction area, and sends these multimodal sensing signals to the control module 2; the control module 2 is connected to the sensing module 4, and is used to identify the pet's behavior type based on the received multimodal sensing signals, and control the operation of the pet air purifier according to the pet's behavior type.

[0035] In this embodiment, the specific contents of the interaction kit 3 and the sensing module 4 are not limited, and are determined based on actual needs. For example, the sensing module 4 includes pressure sensors, weight sensors, tactile sensors, etc.

[0036] It should be noted that the interactive kit 3 in this embodiment is a replaceable kit. By setting the interactive kit 3 outside the purifier body 1 (i.e., the unit body) as a dedicated pet interaction area, the pet's natural scratching and interaction behaviors are transformed from "damaging the device shell" into "normal interaction behaviors." This satisfies the pet's natural needs for scratching, climbing, and interaction while preventing the pet from directly scratching and damaging the purifier body shell, fundamentally resolving the contradiction between the traditional purifier's "protective shell" and "pet's natural behavior." Furthermore, when the interactive kit 3 wears out, only this component needs to be replaced, without replacing the entire unit or the body shell, significantly reducing long-term maintenance costs and extending the overall lifespan of the unit.

[0037] Furthermore, in this embodiment, the sensing module 4 is arranged on the inner side (i.e., the inner wall) of the purifier body 1, and its height position corresponds exactly to the external interactive kit 3. It can collect multimodal sensing signals during pet interaction, breaking through the limitation of traditional solutions that can only detect "whether the pet is present / how far away". It can distinguish different types of pet behavior, achieve more accurate and richer behavior perception, and provide a reliable basis for the differentiated intelligent control of the purifier.

[0038] This invention relates to a pet air purifier. By incorporating an interactive kit on the outer surface of the purifier body, it provides a dedicated interaction area for pets. This guides natural behaviors such as scratching and clawing that would normally occur on the purifier's outer shell to the interactive kit surface, fundamentally preventing direct damage to the purifier's outer shell. This resolves the conflict between the smooth, enclosed outer shell of existing purifiers and the behavioral needs of pets, achieving a balance between human and pet needs. Simultaneously, a sensing module is placed on the inner side of the purifier body, corresponding to the interactive kit. By collecting multimodal sensing signals generated when the pet interacts with the kit, it provides reliable support for the control module to accurately identify different behavior types. This enables refined pet behavior recognition and differentiated control of the device, significantly improving the device's intelligence and user experience.

[0039] In one specific embodiment, Figure 2This is a structural block diagram of another pet air purifier according to an embodiment of the present invention. It should be noted that the purifier body 1 is injection molded from engineering plastic and is cylindrical in shape, with an annular groove and a slot structure pre-reserved on the lower half of its outer surface. The replaceable interactive kit 3 engages with the main body slot via an inner layer buckle, allowing users to disassemble and replace it by hand without tools; moreover, the interactive kit 3 is made of three layers of materials through hot-pressing composite molding, namely: the outer layer is sisal fiber woven fabric, providing a rough and scratch-resistant texture; the middle layer is foam material, used to buffer scratching impact and protect the internal sensors; the inner layer is a plastic support layer, ensuring the overall rigidity of the kit; its layered structure is as follows: Figure 2 The enlarged section view A in the figure shows the sensor module 4, which includes multiple vibration sensors 41, pressure sensors 42, and capacitive touch sensors 43. These sensors are evenly distributed along the circumference of the inner wall of the purifier body 1 at the height corresponding to the coverage of the interactive kit 3. Their unfolded arrangement is as follows: Figure 2 The diagram is shown in Figure B. The LED strip of the interactive feedback component 5 is an RGB full-color LED strip, which surrounds the edge of the top air outlet 6. The control module 2 (also called the controller) is used to receive multimodal sensor signals and execute recognition and control logic.

[0040] In this embodiment, refer to Figure 2 The interactive kit 3 has a layered composite structure, which includes an inner support layer 33, a middle buffer layer 32 and a surface braided layer 31 in sequence along the direction away from the purifier body 1. The middle buffer layer 32 is used to buffer the interactive impact and protect the internal sensors. The inner support layer 33 is used to ensure the overall rigidity of the interactive kit 3. The interactive kit 3 is detachably connected to the purifier body 1 through the inner support layer 33.

[0041] It should be noted that the buffer layer is sandwiched between the support layer and the braided layer. This not only does not block the signal detection of the internal sensors, but also prevents the hard impact of pet interaction from directly affecting the sensors. While protecting the components, it ensures that multimodal sensing signals such as vibration, pressure, and capacitance can be transmitted normally and accurately to the sensing module, providing structural protection for the accuracy of subsequent pet behavior recognition.

[0042] In this embodiment of the invention, the layered composite interactive kit features three layers that work together seamlessly. The outer woven layer directly supports pets' scratching and clawing behaviors, catering to their natural interactive needs. The middle buffer layer cushions the impact of pet interactions, optimizing the tactile experience of scratching and slapping while reducing the impact on the internal sensing module, protecting sensor components and ensuring sensor accuracy and the purifier's lifespan. The inner support layer provides structural rigidity for the entire interactive kit, preventing deformation under stress and ensuring installation stability and structural durability. Furthermore, the inner support layer allows for a detachable connection to the purifier body. When the interactive kit becomes worn or aged due to long-term pet scratching, it can be disassembled and replaced separately without replacing the entire purifier or its casing, significantly reducing long-term maintenance costs. The detachable structure also facilitates the removal of residual pet hair, dander, and other dirt from the cleaning kit, enhancing ease of use.

[0043] In this embodiment, refer to Figure 2 The surface woven layer 31 includes: a rough texture area 311 and a plurality of elastic mesh areas 312; wherein, the rough texture area 311 is used for the pet to sharpen its claws; the elastic mesh areas 312 deform under the pet's interaction behavior to provide tactile feedback to the pet.

[0044] It should be noted that in this embodiment, the rough textured area 311 occupies most of the surface area of ​​the interactive kit 3. This area is made of sisal fiber woven material and is relatively large to fully cover the area that the pet's forelimbs can reach when standing or sitting, satisfying its frequent scratching instincts. The elastic mesh area 312 is relatively small and is mainly used to provide moderate deformation feedback, satisfying the pet's tactile needs when stretching its body upwards or tentatively scratching. Note that... Figure 2 The flexible grid area 312 has four blocks in the entire replaceable interactive kit 3, and the specific number of blocks can be adjusted according to actual needs.

[0045] Furthermore, the differentiated tactile feedback in the flexible grid area 312 can enhance the attractiveness of the interactive kit 3 to pets, stimulate their desire to explore and play, guide them to actively scratch and interact in this area, further strengthen their habit of fixed-point activity, and reduce their scratching and damage to other indoor areas or non-interactive parts of the air purifier.

[0046] In this embodiment of the invention, the dual-area design of a rough textured area and an elastic mesh area not only satisfies the physiological need of pets to sharpen their claws, but also takes into account their behavioral needs for play and exploration. This is more in line with the natural behavioral habits of pets such as felines, which can reduce pets' aversion to the air purifier, increase pets' acceptance of the device, and further help to achieve a positive coexistence between pets and home appliances.

[0047] In this embodiment, refer to Figure 2 The sensing module 4 includes multiple vibration sensors 41, multiple pressure sensors 42, and multiple capacitive touch sensors 43. The vibration sensors 41, pressure sensors 42, and capacitive touch sensors 43 are arranged sequentially and cyclically along the circumference of the purifier body 1, and the arrangement height of each type of sensor corresponds to the coverage height range of the interactive kit 3. Each vibration sensor 41 is used to collect the vibration signal received by the interactive kit 3 when the pet interacts in the interactive area; each pressure sensor 42 is used to collect the pressure signal received by the interactive kit 3 when the pet interacts in the interactive area; and each capacitive touch sensor 43 is used to collect the capacitive signal generated by the interactive kit 3 when the pet interacts in the interactive area.

[0048] It should be noted that in this embodiment, the three types of sensors are arranged sequentially and cyclically along the circumference of the purifier, forming a continuous annular detection zone that completely covers the circumferential range corresponding to the interactive kit. Regardless of where the pet interacts with the purifier, it can be effectively detected, eliminating blind spots and ensuring consistency and sensitivity in detecting interactions from different locations. Furthermore, the sensor placement height perfectly corresponds to the coverage height of the interactive kit, ensuring precise overlap between the detection area and the core area of ​​pet interaction. This avoids signal attenuation and detection failure caused by misaligned sensor placement, ensuring efficient and accurate acquisition of vibration, pressure, and capacitance signals, thus improving detection reliability and signal quality.

[0049] Furthermore, in this embodiment, multiple pressure sensors 42 can form a pressure sensor array, specifically containing six pressure sensor nodes. This array is configured to construct a spatial topological mapping of the device surface. By acquiring force data (i.e., pressure center of gravity) within a continuous time window through this array, the purifier can accurately depict the area of ​​the contact region and accurately identify displacement phenomena (i.e., climbing behavior) based on the continuous bottom-up coordinate changes of the center of gravity. In addition, the purifier includes six vibration sensors 41 evenly distributed along the circumference. These sensors are configured to continuously acquire mechanical vibration signals after the device casing is subjected to force. The controller performs frequency domain conversion on the acquired time-domain signals, extracting peak values ​​and periodic patterns in specific frequency bands, thereby accurately distinguishing between periodic impacts caused by "grinding" and single instantaneous impacts caused by "slapping." The capacitive touch sensor 43 specifically includes 6 large-area flexible capacitive plates attached to the inner wall. Its design is based on the capacitance change caused by the proximity of a living organism to determine the contact range. Since the area of ​​the plates covered by the large-area contact of the pet's torso (such as rubbing fur) is different from that of the partial contact of the forelimbs (such as scratching), the capacitance change caused by the contact range is orders of magnitude different. The controller can reliably identify the contact range by dividing the capacitance change amplitude into thresholds.

[0050] In this embodiment of the invention, three types of sensors—vibration, pressure, and capacitance—collect interaction signals from different physical dimensions. The complementary features of these multiple signal types allow for cross-verification, overcoming the limitations of a single sensor. This not only determines whether a pet is engaging in interactive behavior but also accurately distinguishes different behavior types such as scratching, climbing, rubbing, and patting, significantly reducing the false judgment rate and providing a reliable data foundation for the differentiated intelligent control of air purifiers.

[0051] In this embodiment, refer to Figure 2 The pet air purifier also includes an interactive feedback component 5. The interactive feedback component 5 is set on the purifier body 1 and connected to the control module 2. It is used to generate corresponding interactive feedback signals based on the control commands output by the control module 2 to guide the pet's behavior.

[0052] It should be noted that in this embodiment, the interactive feedback component 5 can generate matching feedback signals based on the identified different pet behavior types, providing appropriate guidance methods for different behaviors such as scratching, climbing, and patting. This aligns with the pet's visual and auditory perception characteristics and behavioral habits, improving the targeting and effectiveness of behavior guidance. Furthermore, while guiding the pet, the interactive feedback signals can also intuitively present the device's operating status and pet interaction detection results to the user, allowing the user to easily understand the device's working status and the pet's activity status without needing to view the operating interface, thus improving user-friendliness. Specifically, this embodiment, through responsive interactive feedback, changes the traditional air purifier's cold, passive nature as a purely purifying appliance with no interaction with pets. It can stimulate the pet's desire to explore and play, reducing the pet's unfamiliarity and resistance to the device, making the pet more willing to actively approach the purifier and move around in the interactive area, indirectly contributing to improved purification efficiency.

[0053] In this embodiment, refer to Figure 2 The air purifier body 1 is also provided with an air outlet 6 on the top. The air outlet 6 is provided with an air guide plate connected to the control module 2 to adjust the air outlet direction and change the airflow organization direction. The interactive feedback component 5 includes an LED light strip, which is located at the edge of the air outlet 6. The control module 2 generates control commands based on the identified pet behavior type to control the LED light strip to emit colors and / or light effects corresponding to the pet behavior type, providing visual feedback signals to the pet and guiding the pet to focus on the surface of the interactive kit 3 to perform corresponding behavioral interactions.

[0054] It should be noted that in this embodiment, the LED light strip outputs corresponding matching light colors and dynamic lighting effects based on the identified different pet behavior types. This not only matches the pet's visual perception characteristics and helps the pet establish a correspondence between "behavior and feedback", but also more accurately guides the pet to focus on the interactive kit surface to carry out interaction, strengthens the pet's fixed-point activity behavior habits, and further reduces the pet's scratching and damage to other areas.

[0055] Furthermore, in this embodiment, the LED light strip is positioned at the edge of the top air outlet, offering visual guidance advantages. When a pet (such as a cat) is climbing or scratching, its line of sight extends upwards; the top lighting effect is most easily noticed by the pet in an interactive state. It also provides visual airflow cues; as an air purifier, the LED light strip surrounding the air outlet visually links with the device's airflow output, providing clear feedback on the device's operating status to both human users and pets. Additionally, it prevents obstruction and damage; its top placement effectively avoids obstruction by the pet's large body and keeps it away from the high-frequency scratching areas in the lower and middle sections, protecting the light strip components from physical impact. Note that the LED light strip's placement in this embodiment can be adapted to specific needs, such as using a ring-shaped ambient light at the base or vertical slit lights on the body.

[0056] In this embodiment of the invention, an air guide plate at the air outlet and an LED light strip at the edge of the air outlet are also designed in conjunction. By adjusting the air outlet direction through the adjustable air guide plate, the airflow organization can be dynamically adjusted to match the pollution characteristics of different pet behaviors. For example, it can actively guide fiber debris generated by scratching and hair shed from rubbing against the pet into the air inlet, achieving targeted capture of pollution sources. This allows the air purification function to be dynamically linked with pet behavior, greatly improving purification efficiency and accuracy, and breaking through the limitations of passive purification in traditional fixed-direction air purifiers. In addition, placing the LED light strip at the edge of the air outlet ensures that, on the one hand, when the pet is active in the interactive kit area below, its line of sight can clearly capture the light signal, providing strong visual feedback accessibility and ensuring effective behavioral guidance; on the other hand, the light strip is far from the high-frequency scratching area in the lower part of the device, preventing direct damage to the light strip components from pet scratching or external impacts, and it is also less likely to be blocked by the pet's body, ensuring a continuously clear feedback signal.

[0057] In this embodiment, refer to Figure 2 The bottom of the purifier body 1 is also equipped with an air inlet 7, which is the air intake structure at the bottom of the body, used to draw in indoor air and pet hair and debris, and send them into the purification system for processing.

[0058] In one specific embodiment, Figure 3 This is a schematic diagram of the controller according to an embodiment of the present invention.

[0065] It should be noted that the pet air purifier in this embodiment integrates the corresponding control method of this embodiment, which, through the combined action of hardware and software, further ensures the control efficiency and purification effect of the pet air purifier, and achieves true harmony between pets and the device.

[0066] According to embodiments of the present invention, based on the pet air purifier mentioned in the above embodiments, a corresponding embodiment of a control method for a pet air purifier is also provided, applied to the pet air purifier. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0067] This embodiment provides a control method for a pet air purifier, applicable to pet air purifiers. Figure 4 This is a flowchart illustrating the control method of a pet air purifier according to an embodiment of the present invention, as shown below. Figure 4 As shown, the process includes the following steps: Step S401: Obtain the multimodal sensing signals generated by the interactive kit when the pet interacts with the interactive kit.

[0068] It should be noted that when pets scratch, climb, rub their fur, or pat the interactive kit, they will exert physical effects on the kit, such as vibration, pressure, and capacitive contact with their bodies. The foam buffer layer in the kit can conduct the above physical signals to the sensing module inside the body, so as to collect the corresponding signals and send them to the controller to obtain multimodal sensing signals.

[0069] Step S402: Identify pet behavior types based on multimodal sensor signals.

[0070] In this embodiment, this step aims to identify the multimodal sensor signals generated by the pet's interaction with the interactive kit in order to determine what kind of interactive action the pet is performing (such as scratching / climbing / rubbing / patting), thereby providing a basis for subsequent fan speed adjustment, air guidance, and light feedback.

[0071] Step S403: Control the operation of the pet air purifier according to the pet's behavior type.

[0072] In this embodiment, this step aims to dynamically adjust the operation of the purifier based on the identified pet behavior type. It can match the appropriate purification level and airflow mode for different pollution characteristics of different behaviors (such as fiber debris generated by scratching, hair shed from rubbing, loose hair and odors brought up by activities), and treat pollution sources in a targeted manner. Compared with a fixed operation mode, it not only improves the targeting of pollution treatment and purification efficiency, but also avoids the energy waste caused by indiscriminate high-load operation, thus optimizing energy efficiency.

[0073] This invention, by acquiring multimodal sensor signals generated by the pet on the interactive kit, can accurately distinguish different pet behavior types such as scratching, climbing, rubbing, and patting. This overcomes the shortcomings of existing technologies that can only determine whether the pet is present or its general posture, providing a reliable basis for differentiated control. At the same time, it controls the operation of the pet air purifier based on the identified pet behavior type, enabling the purifier to respond specifically to different behaviors. This achieves a leap from "passively avoiding pets" to "actively responding to behavior," improving the depth of interaction and the level of intelligence between the device and the pet.

[0074] This embodiment provides a control method for a pet air purifier, applicable to pet air purifiers. Figure 5 This is a flowchart illustrating another control method for a pet air purifier according to an embodiment of the present invention, such as... Figure 5 As shown, the process includes the following steps: Step S501: Acquire the multimodal sensing signals generated by the interactive kit when the pet interacts with it. For details, please refer to [link to details]. Figure 4 Step S401 of the illustrated embodiment will not be described again here.

[0075] Step S502: Identify pet behavior types based on multimodal sensor signals.

[0076] In this embodiment, the multimodal sensing signals include vibration signals, pressure signals, and capacitance signals.

[0077] Specifically, step S502 above includes: Step S5021: Within a preset time period, when the vibration signal exhibits periodic high-frequency impact characteristics, the pet's contact area on the interactive kit is concentrated and its position is stable based on the pressure signal, and the pet's contact range on the interactive kit is less than a preset threshold and its position is fixed based on the capacitance signal, the pet's behavior type is determined to be scratching behavior.

[0078] It should be explained that the periodic high-frequency impact characteristics of the vibration signal refer to the specific periodic high-frequency impact vibrations produced when felines scratch. This vibration pattern is directly related to the pet's physiological behavior. By using preset characteristic intervals and duration thresholds, scratching can be accurately distinguished from other behaviors. Determining that the pet's contact area on the interactive kit is less than a preset threshold and the position is fixed based on the capacitance signal is determined by the triggering status of each capacitance sensor. That is, when multiple adjacent capacitance sensors are triggered simultaneously, and the contact point distribution exceeds the preset area threshold, it is judged as large-area contact. For example, when a cat rubs its fur, it will have large-area contact with the surface, the pressure distribution is diffuse, and the capacitance contact area is large and continuous, which is clearly different from the concentrated contact during scratching. Note that the specific value of the preset duration in this embodiment can be adaptively adjusted according to actual needs and is not limited in detail here.

[0079] Step S5022: Within a preset time period, when the vibration signal has no periodic high-frequency impact characteristics, the pressure center of the pet's contact area on the interactive kit is continuously displaced along a preset direction based on the pressure signal, and the contact range of the pet on the interactive kit is greater than a preset threshold and a unidirectional displacement along a preset direction is determined based on the capacitance signal, the pet's behavior type is determined to be climbing behavior.

[0080] It needs to be explained that the pressure center of the pet's contact area on the interactive kit is continuously displaced in a preset direction based on pressure signals. This movement is determined by the continuous changes in the pressure sensor array. That is, when the pressure center displaces in a certain direction (such as from bottom to top) within a continuous time window, and the displacement distance and speed meet the preset range, it is considered movement. For example, when a cat is climbing, it will continuously move upwards, the pressure center will continuously displace upwards, and the capacitive contact area will also expand and move upwards synchronously.

[0081] Step S5023: Within a preset time period, when the vibration signal shows low-frequency continuous small fluctuations, the contact area of ​​the pet on the interactive kit is determined to be diffusely distributed based on the pressure signal, and the contact range of the pet on the interactive kit is determined to be greater than a preset threshold based on the capacitance signal, the pet behavior type is determined to be rubbing behavior.

[0082] Step S5024: Within a preset time period, when the vibration signal exhibits the characteristics of a single instantaneous impact and the pressure signal exhibits the characteristics of an instantaneous spike, the pet's behavior type is determined to be slapping behavior.

[0083] In this embodiment, the judgment features of the four types of behaviors strictly correspond to the actual behavior of pets: scratching behavior matches the characteristics of fixed front paw position and high-frequency periodic scratching; climbing behavior matches the characteristics of body movement, large contact area and continuous positional displacement; rubbing behavior matches the characteristics of body friction, diffuse contact area and continuous small-amplitude vibration; and patting behavior matches the characteristics of instantaneous patting and single impact (i.e., the instantaneous spike feature is represented in the time domain waveform of the pressure signal as a sharp pulse shape with a rapid increase in pressure value within a very short time, reaching a peak and then quickly falling back). Specifically, setting the judgment criteria based on the natural behavioral patterns of pets makes the recognition results more consistent with the actual scenario of family pet ownership, thereby improving the practicality of the entire control logic.

[0084] In this embodiment of the invention, vibration, pressure, and capacitance signals, three different physical dimensions, are used to complement each other and make joint judgments, which breaks through the recognition limitations of a single sensor. Specifically, vibration signals are used to capture the temporal dynamic characteristics of the action, and pressure and capacitance signals are used to reconstruct the spatial distribution and positional change characteristics of the contact. The cross-verification of the above-mentioned multi-dimensional features can effectively eliminate external interference such as environmental vibration and accidental touch, significantly reduce the probability of misjudgment and missed judgment, and ensure the reliability of pet behavior recognition.

[0085] It should be noted that when signals from different sensors conflict in their judgment of the same behavior—for example, a vibration sensor might show periodic high-frequency impacts (grinding characteristics), while a capacitive sensor might show large-area contact (rubbing characteristics)—the device must adhere to a "safety-first decision rule." This means that grinding has the highest priority, followed by climbing, rubbing, and patting, to ensure the stability and reliability of the entire identification and control system. For instance, if the current vibration signal indicates grinding characteristics, even if other signals conflict, grinding will be prioritized. Furthermore, grinding behavior requires special handling (such as reducing fan speed) to avoid startling the pet; therefore, safety takes precedence. This design ensures that when signals are inconsistent, the device will adopt the safest response strategy, avoiding discomfort to the pet due to misjudgment. Therefore, the control method for the pet air purifier in this embodiment also includes: Step a1: When the pet behavior types identified by the multimodal sensor signals are inconsistent, the judgment is made according to the priority order of scratching behavior, climbing behavior, rubbing behavior, and patting behavior, and the pet behavior type with the highest priority is taken as the final pet behavior type.

[0086] It should be noted that in this embodiment, by combining the signal characteristics and interference probabilities of various behaviors, priority ranking can filter out low-priority judgment results that are easily interfered with. For example, false recognition of slapping behavior is easily triggered by instantaneous environmental vibrations or slight touches. Lower-priority slapping behaviors will not cover the judgment of continuous behaviors such as scratching or rubbing, which can effectively reduce erroneous feedback caused by occasional interference (such as sudden flashing light effects or prompting sounds), avoid disturbing pets in a stable interactive state, and ensure the smoothness and comfort of the interactive experience. In this embodiment of the invention, when there is a conflict in multimodal recognition, a corresponding decision scheme based on behavior priority is also designed. Specifically, a unique behavior type result is output through a decision rule with fixed priority. This solves the judgment conflict and logical contradiction problems that are prone to occur in multimodal joint recognition from a mechanism perspective, and avoids confusion in control logic such as fan speed adjustment, air guide plate adjustment, and interactive feedback due to non-unique results, thus ensuring the stability and reliability of the entire recognition and control system.

[0087] Step S503: Control the operation of the pet air purifier according to the pet's behavior type.

[0088] Specifically, step S503 includes: Step b1: When the pet's behavior type is scratching, control the fan of the pet air purifier to run at a reduced speed.

[0089] Step b2: When the pet's behavior type is climbing, control the fan of the pet air purifier to maintain the current speed.

[0090] Step b3: When the pet's behavior is rubbing against its fur, control the fan of the pet air purifier to run at its highest speed.

[0091] Step b4: When the pet's behavior type is patting, control the pet air purifier's fan to maintain the current speed.

[0092] In this embodiment, pet rubbing generates a large amount of loose hair, dander, and odor, constituting a high-pollution scenario. Increasing the speed to the maximum can quickly capture pollutants and purify the air, ensuring purification efficiency. Scratching generates less pollution, and since the pet is in a state of sustained, focused close interaction, slowing down the operation reduces equipment noise and avoids disturbing the pet. Climbing and patting are momentary exploratory behaviors; maintaining the current speed ensures a stable purification rhythm. Specifically, by using a fan speed-differentiated scheme based on pet behavior types, dynamic adaptation of purification intensity to scenario requirements is achieved, helping to improve the balance between purification efficiency and pet-friendly experience.

[0093] It should be noted that when the pet air purifier also includes an air outlet on the top of the purifier body, an air guide plate at the air outlet, and / or an interactive feedback component, wherein the interactive feedback component is an LED light strip, the control method of the pet air purifier in this embodiment further includes: Step c1: When the pet's behavior type is scratching, control the air deflector to tilt downwards to form a circulating airflow, and / or control the LED light strip to display a blue-green light effect.

[0094] Step c2: When the pet's behavior type is climbing, control the LED light strip to display a dynamic gradient yellow-green light effect.

[0095] Step c3: When the pet's behavior type is rubbing, control the air deflector to direct the airflow to the contact area, and / or control the LED light strip to emit a green light effect.

[0096] Step c4: When the pet's behavior type is patting, control the LED light strip to display a blue-purple flashing light effect, and at the same time control the pet air purifier to output a prompt sound to guide the interaction.

[0097] In this embodiment, the content of the prompt sound can be adaptively set according to actual needs.

[0098] It should be noted that this embodiment employs customized airflow strategies tailored to the specific pollution-generating characteristics of different behaviors. Specifically, during scratching behavior, the air guide plate is tilted downwards to create a circulating airflow, which circulates and continuously filters the fiber debris and dust generated during scratching, preventing pollutants from spreading indoors. During pet-rubbing behavior, the airflow is directed directly to the area where the pet comes into contact with the pet, allowing for the targeted extraction of shed hair, dander, and odors, enabling rapid and localized treatment of pollution sources in high-pollution scenarios. Compared to passive purification modes with fixed airflow directions, this embodiment significantly improves the targeting and efficiency of the purification process.

[0099] It should be further noted that the light colors set in this embodiment are based on strict animal visual physiology and cannot be arbitrarily replaced with colors commonly seen in human vision. In particular, the cone cells of the retina in felines primarily perceive blue and green wavelengths (dichromatic vision), and they are essentially "red-green colorblind," having difficulty distinguishing red, orange, brown, etc., which typically appear as varying shades of grayish-yellow to them. Specifically, the color settings are based on the following: ① Blue-green (wavelength 490-510nm) / claw sharpening: Blue / blue-green is the color that cats are most sensitive to and has the highest contrast. It is most eye-catching against an indoor background and is most suitable as a clear "visual cue" target.

[0100] ② Yellow-green (wavelength 550-570nm) / Climbing: Combined with dynamic lighting effects, it can reproduce the color tone of sunlight passing through leaves in nature to the greatest extent, and evoke the instinct to climb in the forest.

[0101] ③ Green (wavelength 510-540nm) / Fur rubbing: Green constant can create a visual sense of shelter from grass and bushes, conveying a safe and stable environmental signal to cats, which is suitable for fur rubbing, a relaxing action.

[0102] ④ Blue-violet (wavelength 420-440nm) / slapping: Short wavelengths have a certain "strange" and foreign object sensation to cats. Combined with high-speed flashing, it is very easy to simulate the characteristics of prey such as insects, thereby inducing its slapping action.

[0103] This invention presents a scheme that integrates airflow control of the air guide plate with multi-sensory interactive feedback based on pet behavior types. It synchronously binds air purification optimization (i.e., airflow control of the air guide plate) and pet behavior guidance (i.e., LED light effects and prompt sound feedback) to behavior recognition logic. In the same scenario, it achieves the dual goals of "precise pollution treatment" and "positive guidance of pets". This breaks through the limitation of traditional air purifiers that can only achieve a single purification function, and enables the device to take into account the core values ​​of air treatment and human-pet harmony.

[0104] It should be noted that when the interactive kit is severely worn, pet scratches will directly impact the internal sensing module and scratch the purifier's outer casing. Furthermore, the worn and aged woven layer alters the transmission characteristics of vibration, pressure, and capacitance signals, easily leading to misjudgments in behavior recognition. Therefore, this embodiment measures the wear of the kit by accumulating the total duration of scratching behavior to provide early warning of wear. It can proactively push replacement reminders when the kit reaches a critical wear level, not only avoiding sensor damage and scratches caused by surface breakage, extending the lifespan of the entire unit and sensing components, and reducing maintenance costs, but also ensuring timely kit replacement to maintain the consistency of sensor signal transmission, thereby guaranteeing the accuracy of multimodal behavior recognition and ensuring the continuous and stable effectiveness of supporting control strategies such as fan speed adjustment, airflow regulation, and light feedback. Therefore, the control method of the pet air purifier in this embodiment also includes: Step d1: Accumulate and record the total duration of the claw-grinding behavior.

[0105] Step d2: When the total trigger duration reaches the preset maintenance duration threshold, control the pet air purifier to send an interactive kit replacement reminder.

[0106] In this embodiment, the specific value of the preset maintenance time threshold is determined based on the actual lifespan of the kit. Specifically, this embodiment takes into account the damage caused by pet scratching behavior to the interactive kit, and measures the wear and tear of the kit by accumulating the total scratching time. This can provide early warning of wear and tear, thereby extending the lifespan of the entire device and sensing components, and greatly reducing maintenance costs.

[0107] In one specific embodiment, based on Figure 2The structure of the pet air purifier is described, and corresponding control logic is proposed. The controller collects signals from various vibration sensors in real time, continuously monitoring the peak frequency characteristics, amplitude intensity characteristics, and duration characteristics of the signals. When the vibration signal simultaneously exhibits a periodic high-frequency impact pattern, the signal intensity is within the preset claw-grinding behavior characteristic range, and the above pattern continues for more than a preset judgment duration (the "preset judgment duration" is a time set to prevent system misjudgment caused by accidental pet contact. This preset judgment duration is preferably 1 to 3 seconds. Because feline claw-grinding behavior is continuous and rhythmic, the duration of accidental collisions is usually less than 1 second. When the periodic high-frequency impact signal continues for 1 to 3 seconds, interference can be eliminated, and it can be accurately confirmed as claw-grinding behavior. Furthermore, the "continuous preset duration" for the end of the behavior is preferably 3 to 5 seconds to accommodate brief periods or pauses during the claw-grinding process), the system determines that the pet is engaged in claw-grinding behavior. After determining claw-grinding behavior, the controller synchronously executes the following control strategies: Fan control: Reduce the fan speed to a preset low-noise level. Based on feline auditory physiology, cats have a much higher hearing sensitivity than humans; reducing the speed can prevent noise from startling pets focused on scratching. Airflow organization: The air guide assembly is controlled to tilt the air outlet grille downwards, creating a localized circulating airflow that actively blows sisal fiber debris and shed claw sheaths generated during scratching towards the air inlet, where they are captured by the filter assembly. Light feedback: A blue-green light (wavelength 490–510nm) is displayed. Blue-green or blue is the color cats can best distinguish, and it is sufficiently conspicuous against a dark background, serving as a visual cue in the scratching area. For detailed control procedures, please refer to [link / reference needed]. Figure 6 ,include: 1. Multimodal sensor signal acquisition.

[0108] In this embodiment, the controller simultaneously acquires three types of sensor data: vibration sensor signals, pressure sensor signals, and capacitive touch sensor signals, serving as the raw data foundation for subsequent identification of all behaviors. Specifically, the controller simultaneously acquires vibration / pressure / capacitance sensor signals in fixed time window units.

[0109] 2. Multimodal behavior recognition, device-differentiated control logic, and interactive effects.

[0110] It needs to be explained that: ① For the identification of periodic high-frequency impacts of vibration: The vibration sensor used in this solution continuously collects mechanical vibration signals after the equipment shell is subjected to force; the controller performs frequency domain transformation (such as Fast Fourier Transform) on the collected time-domain signals to extract the peak value and periodicity of specific frequency bands (such as the characteristic frequency generated by the friction between cat claws and sisal fibers), thereby accurately distinguishing the periodic impact of "claw grinding" from the single instantaneous impact of "slapping". ② For the identification of pressure contact area and displacement: This solution does not use a single pressure sensor, but rather a pressure sensor array "uniformly distributed along the circumference of the inner wall of the body"; this array constructs a spatial topological mapping of the equipment surface. By analyzing the force data (i.e., pressure center of gravity) of different nodes in the array within a continuous time window, the controller can accurately depict the size of the contact area. When the pressure center of gravity undergoes a continuous coordinate change from bottom to top over time, it can be accurately identified as displacement (i.e., climbing behavior). ③ Determining the capacitive contact range: Capacitive touch sensors work by detecting the capacitance change caused by a living organism approaching. When a pet's torso is in close contact with a large area (e.g., during grooming) or its forelimbs are in partial contact (e.g., during scratching), the area of ​​the plates covered and the resulting capacitance change differ by orders of magnitude. The controller can reliably identify the contact range by applying thresholds to the capacitance change amplitude.

[0111] In this embodiment, the process aims to achieve behavior classification through multimodal signal collaborative analysis. The characteristics of each behavior are defined as follows: Grinding behavior: Vibration is a periodic high-frequency impact; pressure is concentrated in the contact area and its position is stable; capacitance is a small contact range and its position is fixed. Climbing behavior: Vibration is not a periodic impact; pressure is continuous upward displacement of the center; capacitance is large-area contact and synchronous upward movement. Rubbing behavior: Vibration is a low-frequency, continuous, small-amplitude fluctuation; pressure is large-area contact and its distribution is diffuse; capacitance is large-area continuous contact. Slapping behavior: Vibration is a single, instantaneous impact; pressure is an instantaneous high-pressure spike; capacitance is not a necessary condition.

[0112] Note that in rare cases where multiple signal characteristics indicate inconsistent behavior, a safety-first decision rule is followed: claw sharpening has the highest priority, followed by climbing, rubbing, and patting. If a signal does not meet all the characteristic conditions for any behavior, the current operating mode remains unchanged. When periodic impact vibrations are detected, pressure areas are concentrated and stable, and the capacitive contact range is small and overlapping, it is determined to be claw sharpening behavior, and the corresponding operating mode is executed.

[0113] In this embodiment, climbing behavior is defined as follows: when the pressure center shifts upwards from bottom to top within a continuous time window, the capacitor contacts a large area and moves upwards synchronously, and the vibration is without periodic impact, climbing behavior is identified. At this time, maintaining the current fan speed and using LED lights that display a yellow-green hue (wavelength 550–570nm) with dynamic gradients maximizes the cat's visual attention and stimulates its desire to explore. Since climbing involves spatial movement, dynamic lighting effects simulate the swaying light spots between leaves, evoking its primal instinct to climb in the forest. If the pressure center moves upwards to the top area, the top airflow can be briefly enhanced, providing a playful airflow interaction.

[0114] In this embodiment, rubbing behavior is defined as follows: when there is large-area contact with the capacitor, the pressure distribution is diffuse, and the vibration is mainly low-frequency continuous fluctuation, it is determined to be rubbing behavior. At this time, the fan speed is increased to the highest level to increase the intake suction, and the air guide plate is controlled to direct the airflow to the contact area, and the LED strip outputs a solid green light. Green (wavelength 510–540nm) is located in the cat's visual sensitive area, which is consistent with the color of grass and shade, creating a sense of security for the cat as if it were protected by vegetation. The solid light is used to convey a stable device status signal.

[0115] In this embodiment, the slapping behavior is defined as follows: when a momentary high-pressure spike occurs, lasting for an extremely short time, and the vibration corresponds to a single impact response, it is determined to be a slapping behavior. At this time, the fan mode remains unchanged, the LED light displays a blue-violet color (wavelength 420–440nm) and flashes rapidly, while a short alert sound is played. Since the short-wavelength blue-violet color is unusual for cats and has a predatory feel, it induces slapping. The rapidly flashing light spot can stimulate the cat's slapping. The short alert sound establishes a causal association between the pet and the slapping, indicating that the device has sensed contact.

[0116] In summary, through the differentiated control logic of the pet air purifier described above, the device can not only distinguish different types of pet behavior, but also provide the most suitable response based on behavioral principles for each behavior. This upgrades the purifier from a simple air handling device into a family partner that pets are willing to actively interact with, truly achieving a positive coexistence between pets and home appliances.
