[0048] 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.

[0049] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations; and the acquisition, storage, processing, transmission, etc. of data must comply with relevant laws and regulations. In the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned, which should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0050] As mentioned in the background technology, in the existing field of air purification technology, photocatalytic technology has been widely used in various air purification systems due to its characteristics of efficiently decomposing harmful substances in the air. However, the current air purification system based on photocatalytic technology has a significant disadvantage: during long-term operation, dust, particulate matter and other impurities in the air will gradually accumulate on the surface of the photocatalytic device. These impurities will not only cover the active sites of the photocatalytic device, reduce its catalytic decomposition efficiency, and affect the air purification effect, but also shorten the service life of the photocatalytic device. In traditional technology, when impurities on the surface of the photocatalytic device accumulate to a certain extent and need to be cleaned, the entire air purification system can only be shut down, and then the photocatalytic device is disassembled for separate cleaning, and then reinstalled back into the system after cleaning. This process is cumbersome to operate, consumes a lot of manpower and time costs, and has the problem of high cleaning costs.

[0051] Based on this, Figure 1As shown, an air purification system is provided, including a shell 1, and a fan 2, a photocatalytic device 3, a cleaning device 4, a motor (not shown in the figure) and a control device (not shown in the figure) arranged in the shell 1; the control device is connected to the fan 2, the photocatalytic device 3, and the motor; an air inlet 5 and an air outlet 6 are provided on the shell 1; the control device is used to control the start of the fan 2 so that the shell 1 inhales air through the air inlet 5; the photocatalytic device 3 is arranged between the fan 2 and the air outlet 6; the control device is also used to control the photocatalytic device 3 to catalytically decompose the air; the motor is connected to the photocatalytic device 3 and the cleaning device 4; the control device is also used to control the motor to drive the photocatalytic device 3 to move in a first direction, and control the motor to drive the cleaning device 4 to move in a second direction; the first direction and the second direction have reverse components; the cleaning device 4 is arranged on the surface of the photocatalytic device 3, and is used to clean impurities on the surface of the photocatalytic device 3 during movement.

[0052] Among them, the shell 1 is the external protection and containment structure of the air purification system, which is used to integrate components such as the fan 2, photocatalytic device 3, cleaning device 4, motor and control equipment to form a complete purification unit, and at the same time provide a channel for the entry and exit of air. The fan 2 is the power device in the air purification system. It generates airflow by rotation, allowing air to enter the shell 1 from the air inlet 5, and then be discharged from the air outlet 6 after internal treatment. The photocatalytic device 3 is a device that uses the principle of photocatalysis to decompose and purify pollutants in the air. Under light conditions, the photocatalyst in the photocatalytic device 3 can stimulate the production of highly oxidizing substances, decomposing VOCs (Volatile Organic Compounds) and bacteria in the air into harmless substances.

[0053] The cleaning device 4 is a device for removing impurities from the surface of the photocatalytic device 3, ensuring that the photocatalytic device 3 can maintain a good working condition and improve the purification efficiency. The motor is a device that provides power for the movement of the photocatalytic device 3 and the cleaning device 4, and can drive the corresponding device to move in a specific direction according to the instructions of the control device. The control device is responsible for coordinating and controlling the operation of various components such as the fan 2, the photocatalytic device 3, and the motor to realize the automation and intelligence of the air purification process. The air inlet 5 is the channel for air to enter the shell 1, and is usually set at a suitable position of the shell 1 to ensure that the air can smoothly enter the system for purification. The air outlet 6 is the channel for the purified air to be discharged from the shell 1, and the clean air is delivered to the surrounding environment.

[0054] Specifically, the air purification system in this embodiment consists of multiple key components that work together to achieve efficient air purification. Housing 1 forms the foundational structure of the entire system, systematically housing components such as the fan 2, photocatalytic device 3, cleaning device 4, motor, and control device. This provides a stable and enclosed space for air circulation and purification. Housing 1 is provided with an air inlet 5 and an air outlet 6. The air inlet 5 serves as the entrance for outside air to enter the system. Its strategic location and design ensure smooth air flow into housing 1. The air outlet 6 serves as the outlet for purified air, delivering clean air to the surrounding environment and improving air quality. The control device plays a crucial role in coordination and control. It is closely connected to the fan 2, photocatalytic device 3, and motor, enabling real-time monitoring and control of the operating status of each component. When the air purification system needs to be activated, the control device issues a command to start fan 2. The fan 2 generates a powerful airflow through its own rotation, acting as an invisible driving force, rapidly forcing air from the air inlet 5 into housing 1, providing a sufficient air source for subsequent purification.

[0055] The photocatalytic device 3, located between the fan 2 and the air outlet 6, is the core purification unit in the air purification process. As air flows through the photocatalytic device 3 under the propulsion of the fan 2, the control device promptly activates the photocatalytic device 3. Under specific lighting conditions, the photocatalyst within the photocatalytic device 3 is activated, producing active substances with strong oxidizing properties. These active substances react chemically with harmful substances such as organic pollutants and bacteria in the air, breaking them down into carbon dioxide, water, and harmless organic matter, thereby purifying the air.

[0056] The motor provides power support for the movement of the photocatalytic device 3 and the cleaning device 4 in the system. It is connected to the photocatalytic device 3 and the cleaning device 4 respectively, and can accurately drive the photocatalytic device 3 to move in a first direction and simultaneously drive the cleaning device 4 to move in a second direction according to the instructions issued by the control device. The first direction and the second direction here have opposite components. This design allows the cleaning device 4 to fully contact the surface of the photocatalytic device 3 during movement. The cleaning device 4 is arranged on the surface of the photocatalytic device 3. Driven by the motor, it continuously removes dust, decomposition products and other impurities accumulated on the surface of the photocatalytic device 3 during operation. Through regular cleaning, it can ensure that the surface of the photocatalytic device 3 is always clean, maintain its good working performance and purification efficiency, and extend the service life of the device. For example, in this embodiment, the fan 2, the photocatalytic device 3, and the cleaning device 4 are all coaxially arranged to ensure the air purification effect. In addition, the cleaning device 4 can be linked to the motor through a gear set.

[0057] In the above-mentioned air purification system, the control device is connected to the fan, photocatalytic device and motor, which can realize the coordinated control of various components. At startup, the control device controls the operation of the fan so that the shell inhales air through the air inlet, and then controls the photocatalytic device to catalytically decompose the inhaled air, thereby realizing the basic process of air purification. In addition, by setting a motor to connect the photocatalytic device and the cleaning device, and the control device controls the motor to drive the photocatalytic device to move in a first direction and the cleaning device to move in a second direction with an opposite component to the first direction, the cleaning device can directly perform cleaning operations on the surface of the photocatalytic device during its operation, effectively solving the problem of disassembly of the photocatalytic device for cleaning, avoiding the tedious operations, waste of manpower and time costs and equipment damage risks caused by disassembly and cleaning, and significantly reducing the cleaning cost.

[0058] In one embodiment, the control device is specifically configured to control the motor to drive the photocatalytic device to rotate in a first direction, and control the motor to drive the cleaning device to rotate in a second direction.

[0059] The first direction is the direction set by the control device controlling the motor to drive the photocatalytic device. The second direction is the direction set by the control device controlling the motor to drive the cleaning device, and is opposite to the first direction. For example, if the first direction is clockwise, the second direction is counterclockwise. Conversely, if the first direction is counterclockwise, the second direction is clockwise.

[0060] Specifically, the air purification system begins operation, and the control device immediately activates its control functions. It first issues a command to the motor, which begins operating upon receiving the command, providing power for the rotation of the photocatalytic device and the cleaning device. For the photocatalytic device, the control device explicitly controls the motor to rotate it in a first direction. During rotation, the photocatalyst within the photocatalytic device is more fully exposed to air and light, allowing it to more effectively perform its purification function, decomposing and transforming airborne pollutants. Simultaneously, the control device also issues a command to the motor driving the cleaning device, controlling it to rotate in a second direction, which is opposite to the first direction. This counter-rotating arrangement creates relative, more comprehensive friction and contact between the cleaning device and the surface of the photocatalytic device during movement. As the cleaning device rotates, it effectively removes impurities, such as dust and decomposition residues, that accumulate on the surface of the photocatalytic device during air purification, ensuring that the surface remains clean and maintaining its excellent purification performance.

[0061] In this embodiment, the control device causes the photocatalytic device and the cleaning device to rotate in opposite directions, which can efficiently remove impurities on the surface of the photocatalytic device, ensure that it can continuously and stably perform its purification function, and effectively improve the overall purification effect and service life of the air purification system.

[0062] In one embodiment, Figure 2 As shown, the photocatalytic device includes a catalytic component 31 and an illumination component 32; the illumination component 32 is connected to a control device; the control device is also used to control the light emitted by the illumination component 32; the catalytic component 31 is located in the illumination area of ​​the illumination component 32, and a catalytic reaction occurs under the illumination of light.

[0063] Among them, the catalytic component 31 is the part of the photocatalytic device where the catalytic reaction actually occurs. Its surface is usually loaded with photocatalysts, which can trigger chemical reactions under light conditions and convert pollutants in the air into harmless substances. The light component 32 is a component in the photocatalytic device that provides light to the catalytic component 31. It can generate light of a specific wavelength and intensity to activate the photocatalyst on the surface of the catalytic component 31. Exemplarily, the catalytic component 31 can include 3 layers of concentric disks, each layer is 10 cm apart, and the surface of the photocatalytic component 31 is designed with wavy protrusions to increase the specific surface area and improve the effective contact area; the surface is coated with a TiO2 / graphene composite photocatalytic layer (thickness 50-100nm), and the catalytic plate is driven by a motor to rotate intermittently (speed 5-10r / min) to increase the contact area and residence time between the air and the catalytic surface, thereby improving the degradation efficiency.

[0064] Specifically, the photocatalytic device, as a crucial component of the air purification system, undertakes the critical task of purifying the air. It primarily consists of a catalytic component 31 and an illumination component 32. The illumination component 32 is connected to a control device, enabling precise control of its operation. When the air purification system is activated, the control device issues control commands to the illumination component 32 based on actual needs. Upon receiving these commands, the illumination component 32 begins operating, emitting light of a specific wavelength and intensity. The catalytic component 31 is positioned within the illumination area of ​​the illumination component 32, allowing the light emitted from the illumination component 32 to directly impinge on the catalytic component 31. Under the illumination of this light, the photocatalyst on the surface of the catalytic component 31 is activated, triggering a series of complex chemical reactions. These reactions decompose harmful substances such as organic pollutants and bacteria in the air into harmless substances such as carbon dioxide and water, thereby purifying the air. By controlling the light emitted by the illumination component 32, the control device can flexibly adjust the intensity and efficiency of the catalytic reactions based on varying air quality conditions and usage scenarios, ensuring that the photocatalytic device always operates at optimal levels. Exemplarily, the catalytic component 31 can adopt a concentric disc-shaped photocatalytic plate with a TiO2 / graphene composite photocatalytic layer (thickness 50-100nm) sprayed on the surface, and the lighting component 32 can adopt an ultraviolet lamp, which is arranged around the photocatalytic plate and enhances the light intensity utilization rate through the reflective coating.

[0065] In this embodiment, the control device controls the light assembly, so that the catalytic assembly efficiently catalyzes under suitable light, and the purification efficiency can be flexibly adjusted according to actual conditions, thereby effectively improving the air purification effect and the adaptability of the system.

[0066] In one embodiment, the number of catalytic assemblies is multiple; the cleaning device includes multiple sub-cleaning assemblies; the system further includes an image detection device; the image detection device is configured to collect surface images of the catalytic assemblies; and the control device is specifically configured to, in a case where a target image meeting the dirt condition exists in the surface images, control the motor to drive a target sub-cleaning assembly corresponding to a position to which the target image belongs to move in the second direction.

[0067] In one embodiment, the number of catalytic assemblies is multiple; the cleaning device includes multiple sub-cleaning assemblies; the system further includes an image detection device; the image detection device is configured to collect surface images of the catalytic assemblies; and the control device is specifically configured to, in a case where a target image meeting the dirt condition exists in the surface images, control the motor to drive a target sub-cleaning assembly corresponding to a position to which the target image belongs to move in the second direction.

[0068] Specifically, in order to improve the purification effect and stability of the photocatalytic device in the air purification system, multiple catalytic assemblies are arranged in the air purification system. Since the surfaces of the multiple catalytic assemblies will be dirty to different degrees due to adsorption of dust and decomposition residues of pollutants in the air during long-term operation, the cleaning device is equipped with multiple sub-cleaning assemblies, each or multiple sub-cleaning assemblies being responsible for surface cleaning of a catalytic assembly. Meanwhile, an image detection device is introduced, which collects images of the surfaces of the catalytic assemblies at certain time intervals or according to instructions of the control device. The collected surface images of the catalytic assemblies are transmitted to the control device. The control device analyzes and processes the images, and determines whether each surface image is dirty according to a pre-set dirt condition. Once a target image meeting the dirt condition is found in the surface images, the control device quickly determines the position to which the target image belongs, and then finds a target sub-cleaning assembly corresponding to the position. Subsequently, the control device sends a control instruction to the motor, and the motor starts to operate after receiving the instruction, thereby providing power for the target sub-cleaning assembly and driving the target sub-cleaning assembly to move in the second direction, so as to clean the surface of the catalytic assembly that is dirty and restore the purification performance of the catalytic assembly.

[0069] In this embodiment, the purification capacity is improved by multiple catalytic assemblies, the soiled catalytic assembly is accurately positioned by the image detection device, and the corresponding target sub-cleaning assembly is controlled to be cleaned in a targeted manner, so that the cleanliness of the catalytic assembly is effectively ensured, and the efficient and stable operation of the air purification system is maintained.

[0070] In one embodiment, as shown in Figure 3 The system further includes a filter screen 7; the filter screen 7 is arranged between the air inlet 5 and the fan 2, and is used to filter air.

[0071] The filter screen 7 is a key component for filtering in the air purification system, and is usually composed of multiple layers of filtering materials made of different materials, which can intercept particulate matter, dust, hair and other impurities in the air.

[0072] Specifically, the filter screen 7 is arranged between the air inlet 5 and the fan 2. When external air enters the air purification system from the air inlet 5, it will first pass through the filter screen 7. The filter screen 7 can fully play the filtering function by virtue of its own multi-layer filtering material characteristics, and can intercept larger particulate matter, dust, hair and other impurities carried in the air, so as to avoid these impurities entering the subsequent purification link of the system and reduce the burden of the subsequent purification components. After the air is preliminarily filtered by the filter screen, it continues to flow under the action of the fan 2 and enters the photocatalytic equipment and other purification components for deeper purification treatment.

[0073] In this embodiment, the filter screen is arranged between the air inlet and the fan, which can preliminarily filter the air entering the system, effectively intercept large-particle impurities, reduce the burden of subsequent purification components, prolong the service life of the components, and improve the overall purification effect and stability of the air purification system.

[0074] In one embodiment, as shown in Figure 4 The system further includes a dust collection box 8; the dust collection box 8 is used to collect dust scattered after cleaning by the cleaning device.

[0075] The dust collection box 8 is a container component in the air purification system, and mainly functions to collect dust and other impurities to prevent dust from being scattered everywhere in the system or re-entering the air. It can be understood that the dust collection box needs to be replaced when it is full.

[0076] Specifically, during the operation of the system, the cleaning equipment will clean the surfaces of components such as catalytic components and filters in accordance with the instructions of the control device. During cleaning, the dust originally attached to the surfaces of these components will be cleaned off, forming scattered dust. The dust box is reasonably set in a suitable position within the system. When the cleaning equipment completes the cleaning work, the scattered dust will fall into the dust box under the action of air flow or its own gravity within the system, and the dust will be collected together to prevent the dust from re-entering other components of the air purification system or returning to the indoor air, thereby ensuring the cleanliness of the system and the stability of the air purification effect.

[0077] In this embodiment, a dust collection box is provided to collect dust scattered after cleaning by the cleaning equipment, which can effectively prevent the dust from secondary contamination in the system and re-entering the indoor air, maintain the cleanliness of the system, and ensure that the air purification effect is long-lasting and stable.

[0078] In one embodiment, Figure 5 As shown, an air purification method is also provided, the method comprising:

[0079] Step S501: Control the fan to start so that the air inlet draws air.

[0080] Wherein, the fan is arranged in the shell.

[0081] Specifically, the control device sends a command to start the fan installed in the shell. After the fan starts running, suction is generated at the air inlet on the shell, so that the outside air is sucked into the air purification system.

[0082] Step S502: Control the photocatalytic device to catalytically decompose the air.

[0083] The photocatalytic device is arranged between the fan and the air outlet. The air inlet and the air outlet are both arranged on the housing.

[0084] Specifically, the control device controls the photocatalytic device located between the fan and the air outlet to start working. After receiving the start signal, the photocatalyst inside the photocatalytic device is activated under light conditions, catalytically decomposing the inhaled air and converting harmful substances such as organic pollutants and bacteria in the air into harmless substances.

[0085] Step S503 , controlling the motor to drive the photocatalytic device to move in a first direction, and controlling the motor to drive the cleaning device to move in a second direction, so that the cleaning device cleans impurities on the surface of the photocatalytic device during movement, and the cleaned air flows out from the air outlet.

[0086] The first direction and the second direction have opposite components.

[0087] Specifically, the control device simultaneously issues commands to the motors driving the photocatalytic device and the cleaning device. Following the commands, the motors drive the photocatalytic device in a first direction and the cleaning device in a second direction. Because the first and second directions have opposing components, the cleaning device maintains full contact with the surface of the photocatalytic device during movement, effectively removing impurities from its surface. Air purified by the photocatalytic device and the cleaning device ultimately flows out of the air outlet on the housing and returns to the indoor environment.

[0088] In this embodiment, the fan in the shell is first started to inhale air from the air inlet to provide a basic airflow for purification, and then the photocatalytic device arranged between the fan and the air outlet is used to catalytically decompose the air to remove harmful substances; finally, the motor is controlled to make the photocatalytic device and the cleaning device move in directions with opposite components respectively, so that the cleaning device can effectively clean impurities on the surface of the photocatalytic device, ensuring its continuous and efficient purification, and finally making the cleaned air flow out steadily from the air outlet, while comprehensively improving the indoor air purification quality and the stability of the system operation, significantly reducing the cleaning cost.

[0089] In one embodiment, the photocatalytic device includes a plurality of catalytic components; the cleaning device includes a plurality of sub-cleaning components. In the case of this embodiment, Figure 6 As shown, controlling the motor to drive the photocatalytic device to move in a first direction, and controlling the motor to drive the cleaning device to move in a second direction, so that the cleaning device cleans impurities on the surface of the photocatalytic device during movement, includes:

[0090] Step S601: Acquire the surface image of each catalytic component.

[0091] Specifically, the control device can perform image acquisition operations on the surface of each catalytic component to obtain surface images of each catalytic component. These images can clearly reflect the actual conditions of the catalytic component surface and provide a basis for subsequent judgment on whether cleaning is needed.

[0092] Step S602: When there is a target image that meets the dirtiness condition in each surface image, the motor is controlled to drive the target sub-cleaning component corresponding to the position of the target image to move in the second direction, and the motor is controlled to drive the photocatalytic device to move in the first direction, so that the cleaning device cleans impurities on the surface of the photocatalytic device.

[0093] Specifically, the control device analyzes and processes each acquired surface image. When a target image meeting the contamination criteria is found in any of the surface images, the control device responds promptly. First, the control device issues a command to the motor driving the target sub-cleaning component. Upon receiving the command, the motor begins operating, driving the target sub-cleaning component corresponding to the location of the target image in the second direction. Second, the control device simultaneously issues a command to the motor driving the photocatalytic device, causing it to move in the first direction. Through this relative motion, the cleaning device can more effectively remove impurities from the surface of the photocatalytic device, improving the cleaning effect.

[0094] In this embodiment, the surface image of the catalytic component is first obtained to accurately locate the location of the dirt, and then the target sub-cleaning component and the photocatalytic device are controlled to clean in different directions. This collaborative cleaning method can effectively improve the cleaning efficiency and quality of impurities on the surface of the photocatalytic device, ensure the continuous and efficient operation of the photocatalytic device, and thus improve the purification effect of the entire air purification system.
