Detailed Implementation

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] With the booming development of the pet economy, more and more families are keeping cats, dogs, and other pets. However, the cohabitation of humans and pets faces unique air quality challenges, and air pollution in pet-filled homes greatly disturbs the sensory experience of residents. Most current air purification systems adopt a "physical interception + adsorption decomposition" technical approach, using HEPA (High Efficiency Particulate Air) filters to intercept hair and dander, and modified activated carbon to adsorb odors and decompose pollutants. Although some mid-to-high-end products have added ultraviolet (UV) lamps inside the filters, their application has significant shortcomings: Firstly, while ultraviolet lamps in related technology products can inactivate bacteria and viruses, they cannot clean organic matter attached to the filter; the attached organic matter will still rapidly breed bacteria.

[0021] Secondly, activated carbon removes odors primarily through physical adsorption, a passive and limited process. The micropores of activated carbon are easily clogged by moisture and pet dander and oil. Once saturated, it not only loses its deodorizing ability but may even release the adsorbed odors back into the air when temperatures rise, causing secondary pollution.

[0022] To compensate for the shortcomings of activated carbon and to prevent the continued growth of bacteria on the attached organic matter, this application can coat the filter screen with a photocatalytic layer. Under the illumination of light of a specific wavelength (usually in the ultraviolet region), the valence band electrons of the nanoscale semiconductor material in the photocatalytic layer are excited and jump to the conduction band, forming electron-hole pairs: the holes react with water molecules to generate hydroxyl radicals, and the electrons react with oxygen molecules to generate superoxide radicals. These two radicals have strong oxidizing properties and can oxidize and decompose organic matter such as formaldehyde and benzene into carbon dioxide and water, and destroy the cell walls of bacteria attached to the filter screen.

[0023] In addition, to ensure effective decomposition, sterilization, and deodorization, this application allows the purification system's fan unit and sterilization lighting device to operate in different modes with different parameters, thereby achieving comprehensive purification of the pet environment. For example, the purification system may include a filter device, a fan device, and a sterilization lighting device; the filter device may be coated with a photocatalytic layer. The photocatalytic layer may contain at least one of titanium dioxide (N-TiO2), silver-supported titanium dioxide (Ag-TiO2), zinc oxide (ZnO), tungsten trioxide (WO3), and tin dioxide (SnO2), or other substances that can be phototriggered to form free radicals capable of decomposing organic matter; this application does not limit this.

[0024] The fan unit can be used to circulate air between the purification system and the environment, thereby drawing ambient air into the purification system for treatment. The germicidal lighting device, in addition to sterilization and deodorization, can also trigger the photocatalyst layer on the filter to generate free radicals, thus decomposing organic matter on the filter. The control method of the purification system will be explained below: Reference Figure 1 The diagram illustrates a flowchart of a control method for a purification system according to an embodiment of this application, which may include the following steps: Step 101: Determine the current operating mode of the purification system.

[0025] In some embodiments, the current operating mode of the purification system can be determined based on the current environmental conditions; for example, the current operating mode may include a first operating mode, a second operating mode, and a third operating mode.

[0026] When the purification system is in its first operating mode, it can sterilize the environment it is designed for; specifically, it can sterilize the air drawn into the purification system from the environment.

[0027] When the purification system is in the second operating mode, it can deodorize the environment it is targeting; specifically, it can deodorize the air drawn into the purification system from the environment.

[0028] When the purification system is in the third operating mode, it can decompose the organic matter in the purification system; specifically, it can decompose the pollutants on the filter device.

[0029] In some embodiments, the current operating mode can be determined as the first operating mode under normal conditions (e.g., when there is no odor); when an odor is detected in the environment, the current operating mode can be determined as the second operating mode; when no sterilization or deodorization is required, the current operating mode can be determined as the third operating mode.

[0030] After determining the current operating mode, the fan unit and the sterilization lighting unit can be operated with the operating parameters corresponding to the current operating mode. Through coating process improvement and special control logic, without changing the main structure, the function of the sterilization lighting unit has been successfully upgraded from a single sterilization dimension to three dimensions: sterilization, deodorization and self-cleaning.

[0031] Step 102: When the current operating mode is the first operating mode, the fan device is operated with the first fan operating parameters and the sterilization lighting device is operated with the first lighting operating parameters to sterilize the environment targeted by the purification system.

[0032] In some embodiments, after determining that the current operating mode is the first operating mode, the first fan operating parameters and the first lighting operating parameters corresponding to the first operating mode can be determined; the first fan operating parameters and the first lighting operating parameters can be parameters that are preset for the first operating mode.

[0033] After determining the operating parameters of the first fan and the first lighting, the fan device can be operated with the first fan operating parameters and the sterilization lighting device can be operated with the first lighting operating parameters, thereby calling the purification system to sterilize and filter the air in the target environment.

[0034] For example, in the first operating mode, the fan can be controlled to operate at a high speed so that more air can quickly pass through the filter to complete the filtration; in addition, the sterilization lighting device can be controlled to operate with first lighting parameters that can output light that destroys the DNA (Deoxyribonucleic Acid) / RNA (Ribonucleic Acid) of microorganisms in the airflow; thereby, sterilization and filtration of the air are achieved.

[0035] Step 103: When the current operating mode is the second operating mode, the fan device is operated with the second fan operating parameters and the sterilization lighting device is operated with the second lighting operating parameters to stimulate the photocatalytic layer to deodorize the environment targeted by the purification system.

[0036] In some embodiments, after determining that the current operating mode is the second operating mode, a second fan operating parameter and a second lighting operating parameter corresponding to the second operating mode can be determined; the second fan operating parameter and the second lighting operating parameter can be parameters that are preset for the second operating mode.

[0037] After determining the operating parameters of the second fan and the second lighting, the fan device can be operated with the second fan operating parameters and the sterilization lighting device can be operated with the second lighting operating parameters, thereby calling the purification system to deodorize and filter the air in the target environment.

[0038] For example, in the second operating mode, the germicidal lighting device can operate with the second lighting operating parameters, thereby outputting light that can trigger the photocatalyst layer to generate free radicals and shining it onto the photocatalyst layer; under the action of the light, the photocatalyst layer can generate free radicals at the filter device; at this time, in order to allow the odorous air to flow slowly through the activated filter device, the fan device can be controlled to operate at a low speed based on the second fan operating parameters.

[0039] Step 104: When the current operating mode is the third operating mode, the fan device is operated with the third fan operating parameters and the sterilization lighting device is operated with the third lighting operating parameters to stimulate the photocatalytic layer to decompose the pollutants on the filter device.

[0040] In some embodiments, after determining that the current operating mode is the third operating mode, the third fan operating parameters and the third lighting operating parameters corresponding to the third operating mode can be determined; the third fan operating parameters and the third lighting operating parameters can be parameters that are preset for the third operating mode.

[0041] After determining the operating parameters of the third fan and the third lighting, the fan unit can be operated with the third fan operating parameters and the sterilization lighting unit can be operated with the third lighting operating parameters, thereby calling the purification system to decompose the pollutants on the filter device.

[0042] For example, in the third operating mode, the sterilization lighting device can operate with the third lighting operating parameters, thereby outputting light that can trigger the photocatalyst layer to generate free radicals. Under the action of this light, the photocatalyst layer can generate free radicals at the filter device. At this time, the fan device can be controlled to operate at an extremely low speed based on the third fan operating parameters, thereby generating a negative pressure suction effect. During this process, based on the negative pressure suction effect and the organic matter concentration gradient formed from the inside to the outside of the filter device, the organic residual pollutants desorbed from the filter device can be continuously and slowly migrated to the side of the filter device closer to the fan device. The photocatalyst coating can continuously and centrally degrade the migrating pollutants, thereby effectively cleaning the filter device and completely avoiding the problem of activated carbon saturation and acidification.

[0043] In this embodiment, the current operating mode of the purification system can be determined first. When the current operating mode is the first operating mode, the fan device is operated with the first fan operating parameters and the sterilization lighting device is operated with the first lighting operating parameters to sterilize the environment targeted by the purification system. When the current operating mode is the second operating mode, the fan device is operated with the second fan operating parameters and the sterilization lighting device is operated with the second lighting operating parameters to stimulate the photocatalytic layer to deodorize the environment targeted by the purification system. When the current operating mode is the third operating mode, the fan device is operated with the third fan operating parameters and the sterilization lighting device is operated with the third lighting operating parameters to stimulate the photocatalytic layer to decompose pollutants on the filter device. Through this embodiment, the fan device and sterilization lighting device of the purification system can be operated with different parameters in different modes, thereby achieving comprehensive purification of the environment and cleaning of the system itself.

[0044] Reference Figure 2 The diagram illustrates a flowchart of another control method for a purification system according to an embodiment of this application, which may include the following steps: Step 201: Detect the particulate matter concentration and odor concentration of the environment targeted by the purification system.

[0045] In some embodiments, the current operating mode can be determined by the concentration of particulate matter and odor in the environment.

[0046] For example, the purification system may also include a first sensor and a second sensor; wherein the first sensor can be used to detect the concentration of particulate matter in the environment. For example, the first sensor can be a laser dust sensor for detecting PM2.5 (Particulate Matter 2.5), dander concentration, etc.

[0047] The second sensor can be used to detect odor conditions in the environment and output the odor concentration; for example, the second sensor can be a semiconductor gas sensor, and the odor concentration can be VOCs (Volatile Organic Compounds).

[0048] Step 202: When the particulate matter concentration is greater than the first threshold and the odor concentration is less than the second threshold, the current operating mode is determined to be the first operating mode.

[0049] After obtaining the particulate matter concentration and odor concentration, the current operating mode can be determined based on these concentrations.

[0050] In some embodiments, when air pollution in the environment is mainly dominated by particulate matter, it can be determined that the current main need is to sterilize and filter the air in the environment; at this time, the current operating mode can be determined as the first operating mode.

[0051] For example, after determining the particulate matter concentration and odor concentration, it can be determined whether the particulate matter concentration is greater than a first threshold and whether the odor concentration is less than a second threshold.

[0052] When the particulate matter concentration is determined to be greater than the first threshold and the odor concentration is less than the second threshold, it can be determined that the air pollution in the environment is mainly dominated by particulate matter; at this time, the current operating mode can be determined to be the first operating mode.

[0053] Conversely, if it is determined that either the "particulate matter concentration is greater than the first threshold" or the "odor concentration is less than the second threshold" condition is not met, other steps can be performed.

[0054] Step 203: When the particulate matter concentration is less than the third threshold and the odor concentration is greater than the fourth threshold, determine the current operating mode as the second operating mode.

[0055] In some embodiments, when the air pollution in the environment is mainly dominated by odors, it can be determined that the air in the environment needs to be deodorized and filtered. At this time, the current operating mode can be determined as the second operating mode.

[0056] For example, after determining the particulate matter concentration and odor concentration, it can be determined whether the particulate matter concentration is less than the third threshold and whether the odor concentration is greater than the fourth threshold.

[0057] When the particulate matter concentration is determined to be less than the third threshold and the odor concentration is greater than the fourth threshold, it can be determined that the air pollution in the environment is mainly dominated by odor; at this time, the current operating mode can be determined to be the second operating mode.

[0058] Conversely, if it is determined that either the "particulate matter concentration is less than the third threshold" or the "odor concentration is greater than the fourth threshold" condition is not met, other steps can be performed.

[0059] Step 204: When the odor concentration is less than the fifth threshold and the particulate matter concentration is less than the sixth threshold, determine the current operating mode as the third operating mode.

[0060] In some embodiments, when the air quality in the environment is good, it can be determined that there is no need to deodorize or sterilize the environment at present; at this time, the third operating mode can be determined as the current operating mode so as to clean the filter device during the standby and idle time of the purification system.

[0061] For example, after determining the particulate matter concentration and odor concentration, it can be determined whether the particulate matter concentration is less than the sixth threshold and whether the odor concentration is less than the fifth threshold.

[0062] When the particulate matter concentration is determined to be less than the fifth threshold and the odor concentration is less than the sixth threshold, the current operating mode can be determined to be the third operating mode.

[0063] Conversely, if it is determined that either the "particulate matter concentration is less than the fifth threshold" or the "odor concentration is less than the sixth threshold" condition is not met, other steps can be performed.

[0064] In this embodiment, the first threshold, second threshold, third threshold, fourth threshold, fifth threshold, and sixth threshold can be set according to actual conditions. For example, the first threshold, third threshold, and sixth threshold are set for particulate matter concentration; their numerical order can be: first threshold > third threshold > sixth threshold.

[0065] The second, fourth, and fifth thresholds are set for odor concentration; their numerical values ​​can be in the following order: second threshold > fourth threshold > fifth threshold.

[0066] In some embodiments of this application, step 204 can be implemented by the following sub-steps: Sub-step 11: Detect whether there are users in the environment.

[0067] In some embodiments, before determining the current operating mode as the third operating mode, it is also possible to detect whether there are users in the environment targeted by the purification system. For example, the presence of users in the environment can be detected by sensors, or by the current time; for example, it can be determined that there are no users between 9:00 and 18:00 on weekdays.

[0068] Sub-step 12: When the odor concentration is less than the fifth threshold, the particulate matter concentration is less than the sixth threshold, and there are no users in the environment, determine the current operating mode as the third operating mode.

[0069] In some embodiments, when the odor concentration is determined to be less than a fifth threshold and the particulate matter concentration is less than a sixth threshold, it can be temporarily determined that the air quality in the environment is good, and there is no need to deodorize or sterilize the environment at this time. At this point, it can be further determined whether there are users in the environment to avoid performing cleaning work in the presence of users and thus affecting them.

[0070] For example, if the odor concentration is less than the fifth threshold, the particulate matter concentration is less than the sixth threshold, and there are no users in the environment, the current operating mode can be determined to be the third operating mode.

[0071] Conversely, if the odor concentration is less than the fifth threshold and the particulate matter concentration is less than the sixth threshold, but there are users in the environment, the current operating mode can be determined to be standby mode, or it can continue to operate according to the previously set default mode. The operating parameters of the default mode can refer to the parameter settings of the first and second operating modes mentioned above, or they can be set separately. This application embodiment does not limit this.

[0072] Step 205: When the current operating mode is the first operating mode, the fan device is operated with the first fan operating parameters and the sterilization lighting device is operated with the first lighting operating parameters to sterilize the environment targeted by the purification system.

[0073] In some embodiments, after determining that the current operating mode is the first operating mode, the first fan operating parameters and the first lighting operating parameters corresponding to the first operating mode can be determined; the first fan operating parameters and the first lighting operating parameters can be parameters that are preset for the first operating mode.

[0074] After determining the operating parameters of the first fan and the first lighting, the fan device can be operated with the first fan operating parameters and the sterilization lighting device can be operated with the first lighting operating parameters, thereby calling the purification system to sterilize and filter the air in the target environment.

[0075] In some embodiments of this application, the above method may further include the following steps: Detect the current temperature of the germicidal lighting device; when the current temperature exceeds the seventh threshold, reduce the output power of the germicidal lighting device.

[0076] In some embodiments, during the operation of the germicidal lighting device, the current temperature of the germicidal lighting device can be detected; if the current temperature of the germicidal lighting device is detected to be greater than a seventh threshold, the output power of the germicidal lighting device can be reduced to protect the germicidal lighting device and extend its service life.

[0077] For example, the germicidal lighting device will operate at high power in the second operating mode; at this time, the current temperature of the germicidal lighting device can be detected, and when the current temperature is greater than the seventh threshold, the output power of the germicidal lighting device can be reduced.

[0078] Step 206: When the current operating mode is the second operating mode, the fan device is operated with the second fan operating parameters and the sterilization lighting device is operated with the second lighting operating parameters to stimulate the photocatalytic layer to deodorize the environment targeted by the purification system.

[0079] In some embodiments, after determining that the current operating mode is the second operating mode, a second fan operating parameter and a second lighting operating parameter corresponding to the second operating mode can be determined; the second fan operating parameter and the second lighting operating parameter can be parameters that are preset for the second operating mode.

[0080] After determining the operating parameters of the second fan and the second lighting, the fan device can be operated with the second fan operating parameters and the sterilization lighting device can be operated with the second lighting operating parameters, thereby calling the purification system to deodorize and filter the air in the target environment.

[0081] Step 207: When the current operating mode is the third operating mode, the fan device is operated with the third fan operating parameters and the sterilization lighting device is operated with the third lighting operating parameters to stimulate the photocatalytic layer to decompose the pollutants on the filter device.

[0082] In some embodiments, after determining that the current operating mode is the third operating mode, the third fan operating parameters and the third lighting operating parameters corresponding to the third operating mode can be determined; the third fan operating parameters and the third lighting operating parameters can be parameters that are preset for the third operating mode.

[0083] After determining the operating parameters of the third fan and the third lighting, the fan unit can be operated with the third fan operating parameters and the sterilization lighting unit can be operated with the third lighting operating parameters, thereby calling the purification system to decompose the pollutants on the filter device.

[0084] For example, in the third operating mode, the sterilization lighting device can operate with the second lighting parameters, thereby outputting light that can trigger the photocatalyst layer to generate free radicals. Under the action of this light, the photocatalyst layer can generate free radicals at the filter device. At this time, the fan device can be controlled to operate at an extremely low speed based on the third fan operating parameters, thereby generating a negative pressure suction effect. During this process, the slight breeze from the fan device can generate a negative pressure suction effect. Based on the negative pressure suction effect and the organic matter concentration gradient formed from the inside to the outside, the organic residual pollutants desorbed from the filter device will continuously and slowly migrate towards the side of the filter device closer to the fan device. The photocatalyst coating can continuously and centrally degrade the migrating pollutants, thereby effectively cleaning the filter device and completely avoiding the problem of activated carbon saturation and acidification.

[0085] In some embodiments of this application, the germicidal lighting device includes a first band component and a second band component; based on this, in the first operating mode, the germicidal lighting device can be controlled in the following manner: Control the first-band component to output the first-band illumination; In some embodiments, the germicidal lighting device may include a first band component and a second band component; wherein the first band component can output a first band of light; for example, the first band of light may be UVC (Ultraviolet C, short-wave ultraviolet), and the second band of light may be UVA (Ultraviolet A, long-wave ultraviolet).

[0086] In the first operating mode, the first band component of the sterilization lighting device can be controlled to output the first band of light according to the first lighting operating parameters in order to sterilize the air inhaled into the purification system.

[0087] In the second operating mode, the sterilization lighting device can be controlled in the following way: Control the second-band component to output the second-band illumination.

[0088] In the second operating mode, the second band component of the sterilization lighting device can be controlled to output second band light according to the second lighting operating parameters, so as to stimulate the photocatalyst layer to generate free radicals to deodorize the air inhaled by the purification system.

[0089] In some embodiments, under the third operating mode, the second band component of the germicidal lighting device can also be controlled to output second band light according to the third lighting operating parameters, so as to stimulate the photocatalyst layer to generate free radicals to decompose and clean the pollutants on the filter device.

[0090] In some embodiments of this application, any of the above methods may further include the following steps: Check for any risk of light leakage from the germicidal lighting device; if there is a risk of light leakage from the germicidal lighting device, stop operating the device.

[0091] In some embodiments, in order to determine the safety of the germicidal lighting application, security terminal logic may be embedded to prevent the light output from the germicidal lighting device from directly shining on the user.

[0092] For example, during the operation of the germicidal lighting device, it is possible to detect whether there is a risk of leakage in the light output of the germicidal lighting device; for example, whether the equipment is tipped over, or whether the filter compartment door is opened.

[0093] If no risk of light leakage is detected in the output light of the germicidal lighting device, the device can continue to operate normally. Conversely, if a risk of light leakage is detected in the output light of the germicidal lighting device, the device can be stopped immediately to prevent the light from directly shining on the user.

[0097] Reference Figure 3 A simplified structural diagram of a purification system according to an embodiment of this application is shown; as follows: Figure 3 As shown, the purification system 300 may include: The filter device 310 is used to filter air; the filter device 310 is coated with a photocatalytic layer 311.

The control device 340 is connected to the fan device 320 and the sterilization lighting device 330. The control device 340 is used to determine the current operating mode of the purification system 300. When the current operating mode is the first operating mode, the fan device 320 is operated with the first fan operating parameters and the sterilization lighting device 330 is operated with the first lighting operating parameters. When the current operating mode is the second operating mode, the fan device 320 is operated with the second fan operating parameters and the sterilization lighting device 330 is operated with the second lighting operating parameters. When the current operating mode is the third operating mode, the fan device 320 is operated with the third fan operating parameters and the sterilization lighting device 330 is operated with the third lighting operating parameters.

[0098] In this embodiment of the application, the purification system 300 may include a filter device 310, a fan device 320, a germicidal lighting device 330, and a control device 340; wherein, the control device 340 may be connected to the fan device 320 and the germicidal lighting device 330 respectively, so as to control the operation of the fan device 320 and the germicidal lighting device 330.

[0099] In some embodiments, the filter device 310 may be used to filter air; for example, the filter device 310 may include modified activated carbon to adsorb pollutants in the air.

[0100] The filter device 310 may be coated with a photocatalyst layer 311, which can generate free radicals under specific light to decompose and sterilize pollutants.

[0101] The fan device 320 may include a fan, which can be used to circulate the air in the purification system 300; specifically, the fan can create negative pressure in the purification system 300 to draw air from the environment into the purification system 300 and discharge it into the environment after being processed by the filter device 310 and the sterilization lighting device 330.

[0102] The germicidal lighting device 330 can be used to output light that can kill germs, or it can output light that can excite the photocatalyst layer 311 to generate free radicals.

[0103] In this embodiment, the control device 340 can first determine the current operating mode of the purification system 300 based on the current environmental conditions. For example, the control device 340 can determine the current operating mode in response to user operation, and can determine the current operating mode after determining the particulate matter concentration and odor concentration of the environment targeted by the purification system 300 through data obtained from sensors.

[0104] In some embodiments, after determining that the current operating mode is the first operating mode, the control device 340 can determine the first fan operating parameters and the first lighting operating parameters corresponding to the first operating mode.

[0105] After determining the operating parameters of the first fan and the first lighting, the control device 340 can control the fan device 320 with the first fan operating parameters and control the sterilization lighting device 330 with the first lighting operating parameters, thereby calling the purification system 300 to sterilize and filter the air in the target environment.

[0106] For example, in the first operating mode, the control device 340 can control the fan device 320 to operate at a high speed so that more air can quickly pass through the filter device 310 to complete the filtration; in addition, the control device 340 can control the germicidal lighting device 330 to operate with first lighting operating parameters that can destroy the DNA and RNA of microorganisms in the airflow; thereby, the sterilization and filtration of the air are achieved.

[0107] In some embodiments, after determining that the current operating mode is the second operating mode, the control device 340 can determine the second fan operating parameters and the second lighting operating parameters corresponding to the second operating mode.

[0108] After determining the operating parameters of the second fan and the second lighting, the control device 340 can control the operation of the fan device 320 with the second fan operating parameters and control the operation of the sterilization lighting device 330 with the second lighting operating parameters, thereby calling the purification system 300 to deodorize and filter the air in the target environment.

[0109] For example, in the second operating mode, the control device 340 can control the operation of the sterilization lighting device 330 according to the second lighting operating parameters, so that the sterilization lighting device 330 outputs light that can trigger the photocatalyst layer 311 to generate free radicals and shines on the photocatalyst layer 311; under the action of the light, the photocatalyst layer 311 can generate free radicals at the filter device; at this time, in order to allow the air with odor to flow slowly through the activated filter device 310, the control device 340 can control the fan device 320 to operate at a low speed based on the second fan operating parameters.

[0110] In some embodiments, after determining that the current operating mode is the third operating mode, the control device 340 can determine the third fan operating parameters and the third lighting operating parameters corresponding to the third operating mode.

[0111] After determining the operating parameters of the third fan and the third lighting, the control device 340 can control the operation of the fan device 320 with the operating parameters of the third fan and control the operation of the sterilization lighting device 330 with the operating parameters of the third lighting, thereby calling the purification system 300 to decompose the pollutants on the filter device.

[0112] For example, in the third operating mode, the control device 340 can control the operation of the sterilization lighting device 330 according to the third lighting operating parameters, so that the sterilization lighting device 330 outputs light that can trigger the photocatalyst layer 311 to generate free radicals and shines on the photocatalyst layer 311; under the action of the light, the photocatalyst layer 311 can generate free radicals at the filter device; at this time, the control device 340 can control the fan device 320 to operate at an extremely low speed based on the third fan operating parameters, thereby generating a negative pressure suction effect.

[0113] During this process, based on the negative pressure suction and the organic matter concentration gradient formed from the inside to the outside of the filter device 310, the organic residual pollutants desorbed from the filter device 310 can be continuously and slowly migrated towards the side of the filter device 310 closer to the fan device 320. The photocatalytic layer 311 coating can continuously and centrally degrade the migrating pollutants, thereby effectively cleaning the filter device 310 and completely avoiding the problem of activated carbon becoming saturated and acidic.

[0114] In some embodiments of this application, the germicidal lighting device 330 includes a first band component and a second band component; The first-band component is used to output the first-band illumination. The second-band component is used to output the second-band illumination.

[0115] In some embodiments, the germicidal lighting device 330 may include a first band component and a second band component; wherein the first band component can output a first band of light; for example, the first band of light may be UVC (Ultraviolet C, short-wave ultraviolet), and the second band of light may be UVA (Ultraviolet A, long-wave ultraviolet).

[0116] In the first operating mode, the first band component of the sterilization lighting device 330 can be controlled to output the first band of light according to the first lighting operating parameters, so as to sterilize the air of the intake purification system 300.

[0117] In the second operating mode, the second band component of the sterilization lighting device 330 can be controlled to output second band light according to the second lighting operating parameters, so as to stimulate the photocatalyst layer 311 to generate free radicals to deodorize the air of the inhalation purification system 300.

[0118] In the third operating mode, the second band component of the sterilization lighting device 330 can also be controlled to output second band light according to the third lighting operating parameters, so as to stimulate the photocatalyst layer 311 to generate free radicals to decompose and clean the pollutants on the filter device 310.

[0119] In some embodiments of this application, the filtration device 310 includes a filter layer and an activated carbon layer arranged sequentially; the side of the activated carbon layer near the fan device 320 is coated with a photocatalyst layer 311.

[0120] In some embodiments, the filtration device 310 may include a filter layer and an activated carbon layer arranged sequentially; wherein, the filter layer may include a pre-filter layer and a HEPA (High Efficiency Particulate Air) layer for filtering large particulate matter; the activated carbon layer may be used to adsorb pollutants such as small particulate matter and harmful gases.

[0121] The fan device 320 and the sterilization lighting device 330 can be installed inside the filter device 310. The filter device 310 can be provided with a filter layer and an activated carbon layer from the outside to the inside. The side of the activated carbon layer near the fan device 320 can be coated with a photocatalyst layer 311. The light output by the sterilization lighting device 330 can shine on the photocatalyst layer 311 to stimulate the photocatalyst layer 311 to generate free radicals, or to sterilize the air filtered by the filter device 310.

[0122] In some embodiments, in addition to performing the above steps, the control device 340 may also perform any step in the control method embodiment of the purification system 300, which will not be repeated here.

[0123] Reference Figure 4 The diagram shows a structural schematic of an air purifier according to an embodiment of this application; the body 360 and part of the purification system 300 of the air purifier 30 are shown in perspective in the schematic diagram; as shown Figure 4 As shown: The air purifier 30 may include a body 360, a pet seat 370, a connection unit 380, a sensor 390, an air inlet 400, an air outlet 410, a purification system 300, and a base 420.

[0124] The main body 360 can be mounted on the base 420; the main body 360 can be connected to the pet seat 370 via the connecting unit 380; the pet seat 370 can be mounted on the top of the main body 360 for pet resting. The air inlet 400 and air outlet 410 can be mounted on the main body 360 according to actual needs; for example, the air inlet 400 can be located at the bottom of the main body 360, and the air outlet 410 can be located at the top of the main body 360; the sensor 390 can be mounted on the main body 360, and the sensor 390 can include a laser dust sensor and a semiconductor gas sensor.

[0125] The body 360 can be an internal cavity, and the purification system 300 can be installed in the cavity; the filtration device 310 of the purification system 300 can include a pre-filter layer 312, a HEPA layer 313, an activated carbon layer 314 and a filter frame layer 315 arranged sequentially from the outside to the inside; the filtration device 310 can be a hollow cylindrical composite filter, and a photocatalyst layer 311 can be attached to the inner surface of the activated carbon layer 314 by a spraying process.

[0126] A support frame 350 can be vertically erected in the center of the main body 360 (inside the hollow cylindrical filter device 310). A sterilization lighting device 330, composed of several UV lamps, can be installed on the support frame 350. Its position ensures that the emitted light can be perpendicularly incident on the surrounding photocatalyst layer 311. A fan device 320 can be installed at the bottom of the support frame 350, inside the hollow cylindrical filter device 310, to create a negative pressure inside the filter device 310, thereby allowing air to enter the purification system 300 from the outside through the air inlet 400 and be purified.

[0127] The control device 340 of the purification system 300 can be installed on the connection unit 380; it can be used to control the entire purifier 30 or only to control the purification system 300, and this application embodiment does not limit it in this way.

[0128] Reference Figure 5 The following is a control logic flowchart of a purification system according to an embodiment of this application: The control device can identify environmental conditions by reading sensor data (volatile organic compounds, PM2.5, operating time), and then control the germicidal lighting device to switch between three functional roles: biological blocker (first operating mode: sterilization mode), chemical reaction activator (second operating mode: photolysis deodorization mode), and self-maintenance device (third operating mode: regeneration mode). Specifically: Sterilization Mode: For example, when a pet becomes active, its running causes hair and dander to be stirred up, and the sensor detects a rapid increase in PM2.5 levels, but the VOCs (Volatile Organic Compounds) odor level remains low. At this moment, the system can determine the primary pollution characteristic and, if it identifies physical pollution as dominant (i.e., particulate matter), activates the sterilization mode. In this mode, the sterilization lighting device outputs a specific spectrum primarily using the UVC sterilization band, set to medium power, directly destroying the DNA and RNA of microorganisms in the airflow of the purification system. The main task of the sterilization lighting device is to inactivate bacteria drawn into the machine along with dander. Simultaneously, the fan operates at high speed to allow more air to quickly pass through the radiation zone, physically intercepting particulate matter through the HEPA layer, using the number of cycles to compensate for the single-cycle sterilization rate.

[0129] Photocatalytic Odor Decomposition Mode: For example, a cat uses a litter box. The sensor detects a sharp spike in VOC levels within a short period. At this moment, the system identifies it as a sudden, dominant chemical odor; in this case, the photocatalytic odor decomposition mode can be activated. In this mode, the sterilization light device switches to its highest power output, focusing on enhancing the UVA wavelength that can stimulate photocatalytic activity, injecting high-energy photons into the inner wall of the filter, causing a high concentration of free radicals to be generated on the photocatalyst surface. At the same time, the system actively limits the fan speed, avoiding the use of the highest setting, because the photocatalytic reaction is a surface chemical reaction that requires time. If the airflow is too high, the odor molecules will not have enough time to reside on the filter surface and will be blown out before they can be oxidized and decomposed. By appropriately reducing the airflow speed and extending the reaction time, the odorous air slowly flows over the activated filter surface, and the odor molecules are fully oxidized and decomposed, thereby significantly improving the chemical decomposition efficiency of a single filtration.

[0130] Regeneration Mode: For example, when the owner is not home during the day and the pet is napping, all air quality indicators are at excellent levels. At this time, the system recognizes a low load / standby state and activates regeneration mode. High fan speed is not required; the fan can operate at a low speed. The intermittent sterilization light device illuminates the photocatalyst, automatically lighting up for 15 minutes every 2 hours. The purpose is not to purify flowing air, but to utilize the oxidation power of the photocatalyst to decompose organic residues (previously adsorbed but not decomposed) adsorbed in situ within the filter's micropores. This process achieves in-situ regeneration of the filter, preventing it from becoming a breeding ground for bacteria due to long-term adsorption of organic matter and avoiding the problem of activated carbon becoming saturated and acidic. Conversely, if all air quality indicators are at excellent levels, but the user is at home, the purification system can be placed in standby mode or set to low speed for continuous environmental purification.

[0131] To ensure the safety of the multi-functional application of the sterilization light irradiation device, the system incorporates the highest priority safety interrupt logic: Regardless of the mode, if a risk of light leakage from the sterilization light device is detected, such as the machine tipping over or the filter compartment door being opened, the logic circuit will cut off the power supply to the sterilization light device within milliseconds to prevent the light from directly hitting the eyes or skin. Conversely, if no risk of light leakage is detected, the sensor data can be read again.

[0132] In addition, considering that the sterilization light irradiation device operates at high power in photolysis deodorization mode, the system will monitor the temperature of the sterilization light irradiation device in real time. If the temperature is too high, the logic will automatically reduce the power of the sterilization light irradiation device to prioritize the protection of hardware lifespan.

[0133] For example, the operating parameters of the fan unit and the sterilization lighting unit in each mode can be referenced as follows: 1. Sterilization Mode: ① First fan operating parameters: Set to high speed operation, for example, adjust the fan speed setting to 80%-100% of the maximum power, and the air volume reaches 400-500m³ / h. 3 / h.

[0134] ② First lighting operating parameters: mainly UVC band (such as 254nm or 275nm), with power set to medium (e.g., 50%-70% of total power).

[0135] 2. Photolysis deodorization mode: ① Second fan operating parameters: Actively limit fan speed, for example, adjust the fan speed to a low to medium setting of 30%-50%, and control the air volume at 150-200 m³ / h. 3 / h, to prolong the residence time of odor molecules on the filter surface.

[0136] ② Second lighting operating parameters: Switch to the highest power output (100% load), focusing on enhancing the UVA band (such as 365nm or 395nm) to maximize the activation of photocatalytic activity.

[0137] 3. Regeneration Mode: ① Third fan operating parameters: Operate at "low speed", for example, adjust the fan speed to 10%-20%, the air volume is very low (about 50m³ / h). 3 / h).

[0138] ②Third lighting operation parameters: Enable intermittent illumination, for example, automatically turn on for 15 minutes every 2 hours.

[0139] Figure 6 The graph shows the trend of odor concentration reduction under the coordinated control of "wind speed-light intensity" during photolysis deodorization mode. In photolysis deodorization mode, the sterilization lighting device operates at high intensity and outputs UVA band light. As the purification system runs for an extended period, the odor concentration in the environment gradually decreases. When the concentration decreases, the fan speed can be reduced, and the sterilization lighting device can be turned off when the odor concentration drops to a threshold value.

The third operating module 704 is used to operate the fan device with the third fan operating parameters and the sterilization lighting device with the third lighting operating parameters when the current operating mode is the third operating mode, so as to stimulate the photocatalyst layer to decompose the pollutants on the filter device.

[0141] In some embodiments, the determining module 701 is used to detect the particulate matter concentration and odor concentration of the environment targeted by the purification system; when the particulate matter concentration is greater than a first threshold and the odor concentration is less than a second threshold, the current operating mode is determined to be a first operating mode; when the particulate matter concentration is less than a third threshold and the odor concentration is greater than a fourth threshold, the current operating mode is determined to be a second operating mode; when the odor concentration is less than a fifth threshold and the particulate matter concentration is less than a sixth threshold, the current operating mode is determined to be a third operating mode.
