[0002] With the acceleration of urbanization and the improvement of people's living standards and happiness, more and more families are choosing to keep pets such as cats and dogs.

[0059] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0060] The embodiment of the present application provides a pet purifier. Figure 1 As shown, the pet purifier includes a purifier body 110, a purification component 120, a cleaning component 130 and a controller 140. Specifically, the purifier body 110 is sequentially provided with an air inlet, a fan component, and an air outlet. When the fan component is started and operated, it can drive air into the air inlet and out of the air outlet.

[0061] The purification assembly 120 is disposed between the air inlet and the air outlet. Air entering the air inlet is purified by the purification assembly 120 before flowing out of the air outlet. As an example, the purification assembly 120 includes a filter that filters and purifies dirt (such as pet hair, dander, dust, etc.) in the passing air.

[0062] The cleaning assembly 130 is disposed on the purifier body 110 . When the cleaning assembly 130 is in operation, it can clean dirt on the filter.

[0063] The fan component and the cleaning component 130 are both electrically connected to the controller 140. The controller 140 is used to respond to the start-up instruction and send a start-up operation signal to the fan component of the pet purifier; the start-up operation signal is used to control the operation of the fan component. During the operation of the fan component, the air is driven to flow out after being purified through the purification component 120 of the pet purifier; the current operating parameters of the fan component are obtained, and the blockage state of the purification component is determined according to the current operating parameters; the blockage state includes unblocked and blocked; when the blockage state of the purification component is blocked, a cleaning signal is sent to the cleaning component 130 of the pet purifier; the cleaning signal is used to control the cleaning component 130 to clean the purification component.

[0064] The structure of the purifier body 110 is not limited to any specific structure. Those skilled in the art can design it by referring to commonly used techniques in the art. For example, an air duct may be provided between the air inlet and the air outlet, and a filter may be disposed within the air duct. Alternatively, wheels may be provided to move the purifier body 110 within the space to be purified.

[0065] In this pet purifier, the controller 140 determines the blockage status of the purification component 120 by obtaining the current operating parameters of the fan component, enabling accurate and timely monitoring of the working status of the purification component 120. When the purification component 120 is clogged, the cleaning component 130 can clean it immediately, avoiding the impact of the blockage on the purification effect. Frequent manual inspection and cleaning are also eliminated, effectively improving the convenience of using the pet purifier.

[0066] In some embodiments, as Figure 2 As shown, the cleaning assembly 130 includes a drive module 131 and a scraper 132. The drive module 131 is mechanically connected to the purification assembly 120 and electrically connected to the controller 140. When the drive module 131 receives a cleaning signal from the controller 140, it drives the purification assembly 120 to move along a first preset direction.

[0067] For details, please refer to Figure 3 The scraper 132 is provided on the purifier body 110 , and the purification component 120 is located within the operating range of the scraper 132 . During the movement of the purification component 120 , the scraper 132 performs a cleaning operation on the purification component 120 .

[0068] It can be understood that the purification component 120 is located within the operating range of the scraper 132, which means that the scraper 132 can contact the filter screen, thereby performing a scraping operation on the filter screen.

[0069] like Figure 3 In the purifier body 110 shown, the filter in the purification assembly 120 is arranged in a ring perpendicular to the mounting plane of the base. The scraper 132 is disposed on the outside of the filter. When the filter rotates clockwise or counterclockwise, the scraper 132 can clean the filter. The first preset direction can be set to a clockwise or counterclockwise rotation direction according to the specific situation.

[0070] The drive module 131 is disposed at the base of the purifier body 110 and may include a drive assembly (e.g., a drive motor) and a wheel 1311. The drive assembly is electrically connected to the controller 140 and mechanically connected to the wheel 1311. Upon receiving a cleaning signal from the controller 140, the drive assembly drives the wheel 1311 to rotate, which in turn drives the filter to move in a clockwise or counterclockwise direction.

[0071] The scraper 132 can extend along the direction in which the filter screen extends. For example, if the filter screen extends perpendicular to the mounting plane of the base, the scraper 132 can extend along this perpendicular direction. As the filter screen moves, the scraper 132 can clean the filter screen's 360° surface and its full axial height.

[0072] In this embodiment, while the filter is being driven to rotate, the scraper 132 is used to scrape off dirt such as pet hair attached to the surface of the filter, thereby completely cleaning the filter. During the cleaning process, no manual intervention is required, and the filter is highly convenient to use.

[0073] In some embodiments, the pet purifier further includes a storage assembly 150 disposed within the purifier body 110. The storage assembly 150 is electrically connected to the controller 140. The controller 140 is also configured to issue a storage signal. Upon receiving the storage signal from the controller 140, the storage assembly 150 receives dirt collected by the purifier assembly 120 by the hair scraper 132.

[0074] The collection signal can be issued later than the cleaning signal. For example, after controller 140 issues the cleaning signal, the drive assembly drives wheel 1311 in response to the cleaning signal, causing the filter to rotate a certain number of times before the drive assembly stops the filter. At this point, controller 140 issues a collection signal, causing collection assembly 150 to collect dirt such as pet hair, thereby preventing the dirt from being re-adsorbed onto the filter, increasing the filter load, or even causing secondary contamination.

[0075] In some embodiments, the storage assembly 150 includes a stopper 151, a storage plate 152, and a storage tray 153. The stopper 151 is disposed on the purifier body 110 and is located in a second preset direction of the scraper 132, which is opposite to the first preset direction.

[0076] The receiving plate 152 is located between the scraper 132 and the limiter 151 , and is connected to the controller 140 . The receiving tray 153 is disposed on the purifier body 110 and is arranged corresponding to the moving path of the receiving plate 152 .

[0077] The receiving plate 152 moves in response to a receiving signal from the controller 140 to collect dirt collected by the scraper 132 from cleaning the filter into the receiving tray 153. The method for moving the receiving plate 152 in response to the receiving signal from the controller 140 is not limited. For example, the receiving plate 152 may be connected to the controller 140 via a translation drive assembly (e.g., a motor assembly), wherein the receiving plate 152 is mechanically connected to the motor assembly, and the motor assembly is electrically connected to the controller 140. Upon receiving the receiving signal, the controller 140 controls the movement of the receiving plate 152 via the motor assembly.

[0078] Specifically, the function of the stopper 151 is to confine dirt and other debris removed by the hair scraper 132 to a specific area (between the stopper 151 and the hair scraper 132) for subsequent collection. The return position of the collection plate 152 is located opposite the collection tray 153 on either side of the travel path. For example, the collection tray 153 is located on one side of the base. As the collection plate 152 descends, it presses the collected pet hair onto the bottom of the collection tray 153. This prevents dirt from being re-adsorbed onto the filter, increasing the filter load and even causing secondary contamination.

[0079] In actual implementation, the storage tray 153 can be a detachable structure to facilitate users to dump the collected dirt in time to avoid the accumulation of hair and the breeding of bacteria and viruses.

[0080] Exemplarily, the pet purifier also includes an interactive module connected to the controller 140, configured to receive user commands and issue corresponding prompts. In some embodiments, the interactive module is a central control screen, through which the user can issue commands to the controller 140, and the controller 140 can also issue information, including prompts to dump waste, for display on the central control screen. In other embodiments, the interactive module can also be a wireless communication module, through which the controller 140 establishes a connection with the user's terminal device (such as a mobile phone, tablet computer, wearable device, etc.).

[0081] In some embodiments, the pet purifier further includes a disinfection assembly 160 disposed on the storage tray 153. The disinfection assembly 160 is electrically connected to the controller 140 and operates upon receiving a disinfection signal from the controller to disinfect the dirt stored in the storage assembly. The structure of the disinfection assembly 160 is configured according to specific circumstances, such as a UV germicidal lamp.

[0082] In this embodiment, by providing the disinfection component 160, dirt can be disinfected in a timely manner, effectively blocking the spread of germs and the like, and improving the health protection level of the pet purifier.

[0083] In some embodiments, the pet purifier also includes a wind pressure sensor arranged on the air inlet side of the filter and a wind pressure sensor on the air outlet side of the filter. Both sensors are electrically connected to the controller 140 and transmit the monitored air inlet side wind pressure parameters and air outlet side wind pressure parameters to the controller 140 respectively.

[0084] When the pet purifier is operating, the controller 140 obtains the inlet and outlet pressure parameters in real time and calculates the pressure difference. Simultaneously, the controller continuously monitors the current operating power of the fan assembly. The purifier assembly is considered blocked only when both the pressure difference is greater than a preset pressure threshold and the current power reaches a preset power threshold.

[0085] In some embodiments, the pet purifier further includes a temperature sensor 161 and a humidity sensor 162 connected to the controller 140 for collecting and transmitting the ambient temperature and humidity to the controller 140. The controller 140 then determines a preset wind pressure threshold and a preset power threshold based on the ambient temperature and / or humidity. By dynamically setting the wind pressure threshold and the power threshold, cleaning control can be more accurately tailored to current conditions, improving the reliability of cleaning control.

[0086] The aforementioned pet purifier activates a self-cleaning process when the filter is determined to be clogged based on the fan assembly's current operating parameters. The filter begins to rotate, with the bottom disc 1311 rotating. During this rotation, the scraper 132 scrapes off pet hair adhering to the filter surface. Simultaneously, a stopper 151 in front of the scraper 132 confines the pet hair removed by the scraper 132 to a specific area. After the filter rotates a certain number of times (the number of revolutions is determined based on test results for different filter sizes), the collection plate 152 descends, pressing the collected pet hair into the bottom storage tray 153, completing the cleaning process. This process eliminates the need for the user to monitor filter clogs, making it highly convenient to use.

[0087] When there is shaved pet hair in the storage tray 153 at the bottom, the controller 140 can also remind the user to pour out the hair in the storage tray 153 by lighting up the applet or corresponding software of the user terminal device and the display interface (such as the central control screen), so as to avoid the accumulation of hair and the breeding of bacteria and viruses, thereby further improving the safety of the pet purifier.

[0088] This application also provides a control method for a pet purifier. In this embodiment, the method is applied to Figure 3 The pet purifier in the example is used for illustration. It is understandable that the method can also be applied to a server, and can also be applied to a system including a pet purifier and a server, and is implemented through the interaction between the pet purifier and the server. The control method of the pet purifier can be implemented by the controller in the pet purifier, or by other external control devices.

[0089] In an exemplary embodiment, the method is applied to Figure 1 or Figure 2 The controller 140 in FIG. 1 is used as an example to illustrate. Figure 4 As shown, the control method of the pet purifier includes the following steps:

[0090] Step 402: In response to the start instruction, a start-up signal is sent to the fan assembly of the pet purifier.

[0091] The start-up signal is used to control the operation of the fan component. During the operation of the fan component, it is used to drive the air to flow out after being purified through the purification component of the pet purifier.

[0092] The start command can be a command issued by the user through an interactive module (such as a central control screen or mobile terminal) to instruct the pet purifier to start running. The start command can also be a command generated internally by the controller. For example, the controller has a built-in timing module that records the last time purification ended. When the cumulative running time reaches a preset threshold (such as 72 hours), a start command is automatically generated. Alternatively, the pet purifier also includes an air quality sensor connected to the controller (such as a PM2.5 sensor, an odor sensor, etc.). The controller generates a start command when it detects that the concentration of pet hair, dander, or odor exceeds a preset threshold based on the detection data fed back by the sensor.

[0093] In response to the start command, the controller sends a start signal to control the fan assembly, driving air from the air inlet into the purifier body, passing through the purification components (such as the filter) and the fan assembly, and finally out of the air outlet. During this process, the purification component filters and purifies the air of dirt such as pet hair and dander.

[0094] Step 404 : obtaining the current operating parameters of the fan assembly, and determining the blockage state of the purification assembly according to the current operating parameters.

[0095] The blocking state includes unblocked and blocked.

[0096] After the fan assembly starts running, the controller continuously obtains the current operating parameters of the fan in the fan assembly. The current operating parameters can be set according to specific circumstances, such as current power, speed, current or wind pressure.

[0097] The filter is the core filtration component of a pet purifier. Its porous structure captures airborne particles such as pet hair, dander, and dust through physical interception and adsorption. Over time, the filter pores gradually become clogged, increasing flow resistance. When the filter's flow resistance increases, the fan must increase air pressure to maintain the target air volume. This process changes the fan's operating parameters. The controller determines the current level of clogs based on the fan's current operating parameters.

[0098] Step 406 : When the blockage state of the purification component is blockage, a cleaning signal is sent to the cleaning component of the pet purifier.

[0099] The cleaning signal is used to control the cleaning component to clean the purification component.

[0100] When the controller determines that the purification component is clogged, it indicates that the filter pores are deeply filled with particulate matter (such as pet hair, dander, and dust). To avoid motor overload and reduced purification performance, cleaning must be initiated immediately. The controller immediately sends a cleaning signal to the cleaning component. The cleaning component's drive module (such as the drive motor and wheel) receives the signal and rotates the filter. Simultaneously, a scraper attached to the outside of the filter scrapes the surface, removing any adhered dirt such as pet hair.

[0101] In actual implementation, the number of rotations of the filter can be set based on specific circumstances, for example, based on test results for filters of different sizes. In some specific embodiments, the filter blockage status can be classified into light, moderate, and severe blockage levels based on the degree of blockage. The controller dynamically adjusts the number of rotations of the rotating cleaning component based on the different blockage levels. For example, the filter can be controlled to rotate 5 times for light blockage, 8 times for moderate blockage, and 10 times for severe blockage, thereby implementing a graded cleaning strategy.

[0102] It can be understood that when the blockage state is not blocked, it means that the filter pores have good permeability and the cleaning effect is stable. At this time, cleaning is not required, which also saves energy.

[0103] The control method of the above-mentioned pet purifier, when receiving the start-up instruction, sends a start-up operation signal to the fan component of the pet purifier; the start-up operation signal is used to control the operation of the fan component to drive the air to flow out after being purified by the purification component of the pet purifier; the current operating parameters of the fan component are obtained, and the blockage state of the purification component is determined according to the current operating parameters; the blockage state includes unblocked and blocked; when the blockage state of the purification component is blocked, a cleaning signal is sent to the cleaning component of the pet purifier; the cleaning signal is used to control the cleaning component to clean the purification component. Therefore, by obtaining the current operating parameters of the fan component to determine the blockage state of the purification component, the working condition of the purification component can be accurately and timely monitored. When the purification component is blocked, the cleaning component can be cleaned in time to avoid affecting the purification effect due to blockage, and there is no need for frequent manual inspection and manual cleaning, which effectively improves the convenience of using the pet purifier.

[0104] In an exemplary embodiment, the current operating parameters of the fan assembly include the current power of the fan assembly, and the step of determining the blockage state of the purification assembly according to the current operating parameters includes the following steps:

[0105] When the current power of the fan component reaches a preset power threshold, it is determined that the blockage state of the purification component is blocked.

[0106] The preset power threshold does not need to be limited and can be a preset fixed value or flexibly adjusted by the controller according to specific circumstances. For example, the power threshold is obtained through experimental testing. During the test, the filter surface can be covered with pet hair to reach a clogged state. The motor power of the fan assembly is tested when it is stable, and this power is used as the preset power threshold.

[0107] Since the more severe the filter clogs, the greater the fan power. Therefore, during the operation of the pet purifier, the controller continuously monitors the current power of the fan component. When the power exceeds a preset threshold, it determines that the filter is clogged and immediately triggers the self-cleaning process, sending a cleaning signal to the cleaning component to clean the filter. This judgment based on fan power data eliminates the need for additional sensors and significantly reduces hardware costs.

[0108] In some embodiments, the step of determining the blockage state of the purification component based on the current operating parameters may further include the following steps:

[0109] When the current power of the fan component reaches a preset power threshold value for a preset time period, it is determined that the blockage state of the purification component is blocked.

[0110] In this embodiment, the preset duration does not need to be limited and can be set according to actual conditions. By setting the duration determination condition, misjudgment caused by instantaneous power fluctuations can be avoided, thereby improving the reliability of cleaning control.

[0111] In an exemplary embodiment, the control method of the pet purifier further includes the following steps:

[0112] Obtain the air pressure parameters on the air inlet and outlet sides of the purification component.

[0113] Furthermore, the step of determining the blockage state of the purification component according to the current operating parameters includes the following steps:

[0114] Determine the wind pressure difference on both sides of the purification component based on the wind pressure parameters on the air inlet side and the wind pressure parameters on the air outlet side;

[0115] When the wind pressure difference is greater than the preset wind pressure threshold and the current power reaches the preset power threshold, it is determined that the blockage state of the purification component is blocked.

[0116] The preset wind pressure threshold does not need to be limited and can be a preset fixed value or can be flexibly adjusted by the controller according to specific circumstances.

[0117] Specifically, the pet purifier also includes a wind pressure sensor arranged on the air inlet side of the filter and a wind pressure sensor on the air outlet side of the filter. Both sensors are electrically connected to the controller and transmit the monitored air inlet side wind pressure parameters and air outlet side wind pressure parameters to the controller respectively.

[0118] While the pet purifier is operating, the controller also obtains the inlet and outlet pressure parameters P1 and P2 in real time and calculates the pressure difference ΔP = P1 - P2. Simultaneously, the controller continuously monitors the current operating power of the fan assembly. The purification assembly is considered blocked only when both the pressure difference ΔP is greater than a preset pressure threshold and the current power reaches a preset power threshold.

[0119] This embodiment uses dual verification of wind pressure difference and power to mitigate potential misjudgments caused by single-parameter detection. For example, an increase in power could be due to voltage fluctuations, or an increase in wind pressure difference could be due to sensor anomalies. This improves the reliability of blockage status detection, ensuring timely detection while significantly reducing false alarm rates. This increases the reliability of cleaning control and, in turn, enhances the reliability of the pet purifier.

[0120] In some embodiments, the control method of the pet purifier further includes the following steps:

[0121] Get the environmental parameters of the pet purifier;

[0122] The preset wind pressure threshold and the preset power threshold are determined according to the environmental parameters.

[0123] The environmental parameters may include at least one of ambient temperature and ambient humidity.

[0124] It is understandable that the degree of clogging caused by dirt on the filter will vary under different environmental conditions. For example, in a high-humidity environment, a small amount of hair adsorbed on the filter will cause clogging; in a low-humidity environment, more hair adsorbed on the filter will cause clogging. Therefore, the preset wind pressure threshold and preset power threshold can be dynamically adjusted in combination with the current environmental parameters. For example, in a high-temperature, low-humidity environment, the air density decreases and the hair dries out, in which case the preset wind pressure threshold and power threshold can be increased; while in a low-temperature, high-humidity environment, the air density increases and the hair becomes wet and easily sticks together, in which case the preset wind pressure threshold and power threshold should be lowered. This makes the cleaning control more in line with the current actual situation and improves the reliability of the cleaning control.

[0125] In actual implementation, the pet purifier also includes a temperature sensor and a humidity sensor connected to the controller to collect and transmit the ambient temperature and humidity to the controller. The controller determines the preset wind pressure threshold and the preset power threshold based on the ambient temperature and / or ambient humidity.

[0126] The controller can incorporate machine learning algorithms to dynamically adjust preset wind pressure and power thresholds based on environmental parameters such as temperature and humidity. Once the current environmental parameters are known, the controller uses the algorithm to make timely adjustments.

[0127] In some embodiments, as Figure 5 As shown, after step 406 , the control method of the pet purifier further includes step 502 .

[0128] Step 502: Send a storage signal to the storage component of the pet purifier.

[0129] In this embodiment, the storage signal is used to control the start-up operation of the storage component. During the operation of the storage component, the storage component is used to store dirt obtained by the cleaning component in the cleaning operation of the purification component.

[0130] Specifically, as the filter rotates, the scraper removes hair and other dirt from the filter, and the limiter confines the removed dirt to a specific area to prevent it from scattering into other areas within the purifier. When the filter stops rotating, the controller sends a collection signal, causing the collection plate to move and collect the dirt removed by the scraper into the collection tray. This prevents dirt from being re-adsorbed on the filter, increasing the filter load or even causing secondary contamination, thereby improving the safety of pet purifier use.

[0131] In some embodiments, as Figure 6 As shown, after step 502 , the control method of the pet purifier further includes step 602 .

[0132] Step 602: Send a disinfection signal to the disinfection component of the pet purifier.

[0133] The disinfection signal controls the activation of the disinfection component, which disinfects the dirt collected by the storage component after the purification component has been cleaned. This timely disinfection of dirt by the disinfection component effectively blocks the spread of germs and other pathogens, enhancing the pet purifier's health protection level.

[0134] In order to better understand the above embodiment, the following is a detailed explanation in conjunction with an optional embodiment. In one embodiment, Figure 7 As shown, the control method of the pet purifier includes the following steps:

[0135] The pet purifier starts running. Specifically, the controller responds to the start instruction and sends a start-up signal to control the operation of the fan component. During the operation of the fan component, the air is driven to flow out after being purified by the purification component, thereby starting the purification work of the room.

[0136] During the purification process, the controller's internal fan power detection module monitors fan power in real time, determining the fan's current power. Simultaneously, the air pressure sensors on the filter's inlet and outlet sides transmit their monitored air pressure parameters to the controller, which then calculates the pressure differential across the filter (i.e., the filter pressure differential).

[0137] When the fan power reaches the preset power threshold W1 and the filter pressure differential reaches the preset pressure differential threshold P, the filter is determined to be clogged with pet hair and the self-cleaning process begins. The controller sends a cleaning signal to the cleaning component. Upon receiving the signal, the cleaning component's drive module (such as the drive motor and wheel) rotates the filter. Simultaneously, a scraper fixed to the outside of the filter scrapes the filter surface, removing attached pet hair and other dirt. A limiter confines the pet hair removed by the scraper to a specific area, facilitating collection by a collection plate. After the filter rotates a certain number of times (e.g., N, where N is a positive integer), the collection plate begins to descend, pressing the collected pet hair into the bottom storage tray, completing the cleaning process.

[0138] When there is shaved pet hair in the bottom storage tray, the controller will also issue a prompt message to remind the user to empty the hair in the bottom storage tray. For example, the corresponding indicator light will light up on the user terminal app (Application) or the display interface of the pet purifier to remind the user to clean the storage tray.

[0139] When it is detected that the fan power is less than the preset power threshold W1, or the filter pressure difference is less than the preset pressure difference threshold P, it is determined that the filter is not clogged by pet hair and does not need to be self-cleaned.

[0140] Furthermore, different purification modes and different cleaning modes can be set for different pets, such as cats, dogs, birds and other pets to meet the diverse needs of users.

[0141] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
