Description

Technical Field

[0001] The invention relates to the field of filter screen cleaning, and in particular to an automatic filter screen cleaning system and method. Background Art

[0002] As an important component for filtering particulate matter and impurities in the air, the filter needs to be cleaned and maintained regularly to ensure the normal operation of the equipment and extend the service life of the filter. Traditional filter cleaning methods mainly rely on manual operations, which have problems such as low efficiency, incomplete cleaning, and easy secondary contamination of dust and hair during the cleaning process. Manual cleaning is not only time-consuming and labor-intensive, but also causes direct contact between the cleaning staff and the deposits, increasing health risks. In addition, since the filter is usually located inside the equipment or in hard-to-reach places, the cleaning work is more cumbersome and difficult.

[0003] Currently, the automatic cleaning of existing purifiers usually relies on simple brushing or blowing mechanisms. These systems are not effective when facing hair, dust and other easily entangled and easily attached accumulations. At the same time, these systems lack effective debris collection and processing mechanisms, which often results in the debris being cleaned up not being processed and collected in time, affecting the subsequent normal operation of the purifier.

[0004] Therefore, a filter screen automatic cleaning system and method are proposed. Summary of the invention

[0005] The present invention provides a filter screen automatic cleaning system and method to solve the above problems existing in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0039] Check the sealing status of the bag opening. If the sealing is incomplete, reseal the bag opening through a secondary pressing operation;

[0040] After confirming that the bag mouth is completely sealed, the packaging unit is controlled to cut off the excess closing rope and the end of the rope is fixed by the sealing device to ensure the stability of the seal;

[0041] After the sealing operation is completed, the automatic packaging unit activates the sealing detection device of the bag opening and checks whether the seal is completely sealed by applying a certain pressure. If the test fails, the sealing operation is performed again until the sealing requirement is met;

[0070] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0071] An embodiment of the present invention provides an automatic filter cleaning system, comprising:

[0072] An acquisition unit is used to acquire a start signal to start the drive unit when the amount of debris on the monitoring filter reaches a preset value;

[0073] A driving unit, used to drive the hair collecting box to reciprocate along a set track according to the current driving mode information;

[0074] A cleaning unit is used to clean the hair scraps on the filter screen into a collection bag provided in the hair collection box through a collection roller installed on the hair collection box during the reciprocating motion of the hair collection box;

[0075] A full load detection unit is used to detect the full load state of the hair debris in the collection bag through the full load detection module and trigger a reminder signal when the hair debris automatically collected and cleaned in the hair collection box reaches a predetermined amount;

[0076] The automatic packaging unit is used to automatically pack and seal the collection bag when a full-load reminder signal is received.

[0077] The working principle of the above technical solution is as follows: air purifiers are widely used to remove hair and dust from the air. Over time, hair will gradually accumulate on the filter, affecting the filtering effect. At this time, the automatic cleaning system will start to work.

[0078] like Figure 5As shown, when the amount of hair debris on the filter reaches a preset value, the acquisition unit receives a signal from the sensor and starts the drive unit of the entire system; the drive unit starts the motor by reading the current drive mode information, and drives the hair collection box to reciprocate along the set track; during the reciprocating motion of the hair collection box, the collection roller installed on the hair collection box contacts the surface of the filter, cleans the hair debris on the filter, and introduces it into the collection bag set in the hair collection box. The design of the collection roller enables it to effectively capture and transfer hair debris to ensure that the filter is thoroughly cleaned. As the cleaning proceeds, the hair debris in the collection bag gradually increases. When the amount of hair debris reaches the preset full load standard, the full load detection unit detects this state through the full load detection module and triggers a reminder signal. Once the full load reminder signal is issued, the automatic packaging unit in the system starts to automatically package and seal the full-load collection bag for subsequent processing or replacement of new bags.

[0079] The beneficial effects of the above technical solution are: the automation of filter cleaning is realized without manual intervention, and the cleaning program is automatically started when the hair debris reaches a certain level to ensure that the filter always maintains the best working condition; through the automatic detection, cleaning, and packaging process, the need for manual regular inspection and cleaning is reduced, thereby reducing labor costs and maintenance workload; because the filter is cleaned in a timely and thorough manner, the blockage and damage caused by long-term accumulation of hair debris to the filter is avoided, thereby extending the service life of the filter; the infrared detection and automatic packaging functions equipped in the system ensure that the hair debris collection bag can be sealed in time when it is full, preventing hair debris from overflowing and polluting the environment. At the same time, it also facilitates the disposal of waste; the system can intelligently start the cleaning process according to the accumulation of hair debris on the filter, and automatically package and manage the cleaned hair debris, simplifying the management process and improving the overall intelligence level of the equipment.

[0080] In another embodiment, the acquiring unit includes:

[0081] The first acquisition module is used to acquire the current lint amount information of the filter during the operation of the filter, wherein the current lint amount information includes the current lint accumulation amount of the filter and the cleaning state information of the filter;

[0082] The second acquisition module is used to acquire a start signal to start the drive unit when it is determined according to the current lint amount information that the lint amount of the filter reaches a preset value, wherein the preset value is used to determine whether the filter needs to perform a drive operation.

[0083] The working principle of the above technical solution is as follows: during the operation of the filter, the first acquisition module continuously monitors the accumulation of hair debris on the filter. This module obtains the current hair debris amount information of the filter through sensors or photoelectric detection technology. This information includes the amount of hair debris accumulated on the surface of the filter and whether the filter needs to be cleaned. When the first acquisition module collects enough data, this information will be transmitted to the second acquisition module. The second acquisition module will analyze this data to determine whether the current hair debris accumulation has reached the preset threshold. If the hair debris amount of the filter reaches or exceeds the preset value, this means that the filtering effect of the filter may have been affected and a cleaning operation is required. Once the second acquisition module determines that the hair debris amount has reached the preset threshold, it will generate a start signal and transmit it to the drive unit. After receiving the signal, the drive unit will start the reciprocating motion of the hair collection box along the set track, and then start to automatically clean the filter.

[0084] The beneficial effects of the above technical solution are as follows: through the coordinated work of the first acquisition module and the second acquisition module, the system can accurately judge the accumulated amount of hair debris on the filter, ensure that the cleaning operation is performed at the appropriate time, and avoid the waste and potential problems of cleaning too early or too late; the system can automatically start the cleaning program before the accumulation of hair debris affects the performance of the filter, ensuring that the filter is always in the best working condition and ensuring the efficient operation of the air filtration system; the system reduces the workload of manual inspection and judgment of whether the filter needs to be cleaned, reduces the labor maintenance cost, and reduces the risk of equipment failure caused by untimely cleaning of the filter; by timely cleaning of the filter, the system avoids excessive accumulation of hair debris, thereby reducing the wear on the filter and related equipment and extending the overall life of the equipment; the system has the function of automatic monitoring and judgment, reduces the necessity of human intervention, improves the intelligence level of the equipment, and makes the entire system more autonomous and efficient.

[0085] In another embodiment, the drive unit comprises:

[0086] The first driving module is used to obtain the current driving mode information of the driving unit, wherein the current driving mode information includes synchronous wheel and synchronous belt driving information, screw drive driving information, and gear rack drive information;

[0087] The second driving module is used to select and execute the corresponding driving mode when it is determined that the driving unit meets the driving conditions according to the current driving mode information, and drive the hair collecting box to reciprocate along the set track by controlling the moving speed and reciprocating frequency of the hair collecting box;

[0088] The third driving module is used to monitor the operating parameters of the driving mode when the hair collecting box reciprocates along the set track, and dynamically adjust the driving mode according to the operating parameters.

[0089] Among them, selecting and executing the corresponding driving mode includes:

[0090] Analyze the current driving mode information to determine whether the driving unit meets the set driving conditions, which include: feasibility of the driving mode, required power requirements, workload range, and driving stability;

[0091] When it is determined according to the current driving mode information that the driving unit meets the driving conditions, the corresponding driving mode is selected and executed, and the driving mode selection includes: selecting one of synchronous wheel and synchronous belt drive, screw drive drive or gear rack drive according to the driving conditions to ensure that the selected driving mode meets the required performance requirements;

[0092] By controlling the moving speed and reciprocating frequency of the hair collecting box, the hair collecting box is driven to reciprocate along the set track. The moving speed of the hair collecting box is controlled according to the selected driving mode to ensure that the hair collecting box moves at a predetermined speed. The reciprocating frequency of the hair collecting box is controlled according to the selected driving mode to ensure that the hair collecting box reciprocates at the set frequency. By real-time monitoring and adjustment of the moving speed and reciprocating frequency, the hair collecting box is ensured to run stably on the set track.

[0093] After executing the driving mode, the operating status of the driving unit is monitored in real time to determine whether the driving unit has any abnormal conditions. If an abnormality occurs, the execution of the current driving mode is stopped, an alternative driving mode is selected according to the abnormality type, and the execution is reselected.

[0094] The working principle of the above technical solution is as follows: Figure 4As shown, the synchronous wheel (4) is one of the core driving devices of the system, and it drives the entire hair collection box moving system to reciprocate along the reciprocating motion track (3) by cooperating with the synchronous belt; the synchronous wheel (4) is connected to the driving module, and is responsible for converting the driving signal into physical motion, and executing the drive by driving the synchronous belt; when the synchronous wheel (4) rotates, the synchronous belt also moves accordingly, thereby driving the hair collection box to achieve linear motion on the track, and the rotation speed of the synchronous wheel (4) determines the movement speed of the hair collection box, and it also has an important control effect on the accuracy and frequency of the reciprocating motion; the track provides a fixed movement path for the hair collection box to ensure that it can reciprocate along the specified direction. The track is fixed on the frame structure of the system, and cooperates with the synchronous wheel (4) and the hair collection box moving seat to form a complete motion system. The track determines the movement range of the hair collection box, so that it can move back and forth within the specified space. The linearity and smoothness of the track have a direct impact on the smoothness of the movement of the hair collection box, and are an important guarantee for the reliability and efficiency of the entire system; The box moving seat (1) is used to support and fix the hair collection box, and realizes its reciprocating motion along the track through the driving system. The hair collection box moving seat is connected with the synchronous belt and the track, and the power is transmitted by the driving of the synchronous wheel (4) so ​​that the hair collection box moves smoothly on the track; the hair collection box moving seat is the direct bearing structure of the hair collection box, which ensures that the hair collection box does not shift or tilt during the movement, and can effectively transmit the force generated by the driving device. The friction between the moving seat and the track must be minimized to ensure the efficiency and accuracy of the movement; the filter screen (2) is fixed at the bottom or relevant position of the hair collection box, and the entire working area can be covered by the movement of the hair collection box, so as to effectively collect impurities in the air. During the movement of the hair collection box, the filter screen (2) is used to capture particulate matter in the environment to prevent it from entering the system or being discharged to the external environment; the synchronous belt is connected between the synchronous wheel and the hair collection box moving seat, and directly converts the rotational motion of the synchronous wheel into the linear motion of the hair collection box. The synchronous belt and the synchronous wheel are closely matched and are responsible for transmitting the rotational driving force of the synchronous wheel to the hair collection box moving seat.

[0095] When the system starts, the first drive module will obtain the current drive mode information of the drive unit. This information includes three drive modes: synchronous wheel and synchronous belt drive, screw drive and gear rack drive. This information can be determined by detecting the signal of the sensor or obtained by the preset value in the system configuration. When the first drive module obtains the current drive mode information, the information will be transmitted to the second drive module. This module will determine which drive mode is most suitable according to the current production environment and task requirements, and select this mode to drive the movement of the hair collection box. For example, if higher accuracy and stability are required in the current environment, the system may choose the screw drive drive mode. When the hair collection box starts to reciprocate along the set track, the third drive module will monitor the operating parameters of the drive mode in real time. These parameters may include speed, acceleration, load conditions, etc. According to these parameters, the system will dynamically adjust the operation of the drive mode. For example, if it is found that the efficiency of the current drive mode decreases when the load increases, the system may automatically adjust the transmission ratio or switch to another more suitable drive mode to ensure the smooth progress of the cleaning process.

[0096] The beneficial effects of the above technical solution are as follows: through the coordinated work of the three drive modules, the system can select the most suitable drive mode according to the real-time working conditions, and dynamically adjust the parameters to adapt to environmental changes. This improves the adaptability and flexibility of the system, and can maintain efficient operation in complex and changing industrial environments. Through precise speed and frequency control, the system can optimize the movement path and efficiency of the hair collection box, thereby reducing energy consumption and improving the cleaning efficiency of the production line. At the same time, the dynamic monitoring and adjustment functions ensure that the system can maintain optimal performance under various load conditions; because the system can dynamically adjust the drive mode and parameters according to the actual working conditions, this reduces the mechanical wear and failure caused by improper drive mode selection, thereby reducing the maintenance cost and downtime of the equipment. Through precise control and dynamic adjustment, the system can reduce the wear of transmission components, extend the service life of the drive unit and the hair collection box, and further reduce the frequency and cost of equipment replacement.

[0097] The system can autonomously determine and select the best driving mode and make dynamic adjustments during operation, reducing the need for manual intervention, improving the automation level of the production line, and enhancing the intelligence of the entire system.

[0098] In another embodiment, the hair scraps on the filter screen are cleaned into a collection bag provided in the hair collection box by a collection roller installed on the hair collection box, including:

[0099] Acquire the reciprocating motion data of the hair collection box, and identify the motion parameters of the current collection drum and the filter position parameters from the reciprocating motion data, wherein the motion parameters include the drum speed and the reciprocating frequency, and the filter position parameters include the relative position of the filter with respect to the hair collection box and the inclination angle of the filter;

[0100] According to the drum speed, reciprocating frequency and relative position of the filter screen, the motion data of the current collection drum is processed in layers to obtain the motion data to be obtained, specifically including: obtaining the filter screen position type from the filter screen position parameters, and obtaining the drum motion type from the drum motion parameters;

[0101] The motion data to be acquired is input into a preset cleaning analysis model to obtain the cleaning result data.

[0102] The working principle of the above technical solution is as follows: In the air purifier, the collection drum is used to capture and filter the particles in the air, while the filter screen further separates the tiny particles. In order to ensure the efficient operation of the system, the system needs to monitor and analyze the status of the collection drum and the filter screen in real time. This task is accomplished by acquiring and processing the reciprocating motion data of the collection drum.

[0103] The system first obtains motion data from the reciprocating motion of the collection drum. This data includes the drum's rotation speed, reciprocating frequency, and the relative position and tilt angle of the filter. These parameters can be collected in real time by sensors installed inside the device.

[0104] The drum speed (ω) and reciprocating frequency (f) can be obtained by measuring the motor speed and the number of reciprocating motions of the drum through sensors. The filter position parameters include the relative position of the filter relative to the hair collection box (x, y, z coordinates) and the inclination angle of the filter (θ).

[0105] With this data, the system can identify the current movement status of the collection drum, such as the rotation speed of the drum and the angle of the filter.

[0106] After obtaining these motion parameters, the system will process the data in layers to simplify the subsequent analysis process: By analyzing the relative position and tilt angle of the filter relative to the hair collection box, the system can classify the filter position. For example, the filter is in a horizontal, inclined or vertical position, and the system will classify the filter position type according to the set threshold. The drum movement type can be classified according to the rotation speed and reciprocating frequency. For example, the system recognizes that the drum is rotating at a low speed, medium speed or high speed, or the reciprocating frequency is at a high frequency, low frequency, etc.

[0107] These classified data will be used as "motion data to be acquired" for subsequent analysis.

[0108] The motion data to be acquired is input into a preset cleaning analysis model, which can be a machine learning model or a physical model based on historical data and expert knowledge. The model will calculate the cleaning effect of the equipment based on the input drum speed, reciprocating frequency and filter position type.

[0109] The cleaning effect (E) is represented by the following function:

[0110] E=f(ω,f,θ)

[0111] Among them, ω is the drum speed, f is the reciprocating frequency, and θ is the inclination angle of the filter. This function can be used to estimate the particle removal efficiency, filter clogging risk, etc.

[0112] Finally, the model outputs cleaning result data, including the cleaning efficiency of the current equipment, the degree of filter blockage, and possible maintenance recommendations.

[0113] Among them, Figure 2 As shown, the hair collecting box realizes the function of collecting and storing hair scraps through the cooperation of the upper and lower parts. The upper body mainly plays the role of fixing and guiding, while the lower body contains the core device for collecting hair scraps, such as the collecting roller and the collecting bag; the upper body of the hair collecting box is relatively simple, usually a rectangular frame structure, and its main function is to serve as the upper cover of the entire hair collecting box, and at the same time provide protection for the collecting roller of the hair collecting box. The upper body contains magnets, which are used to quickly connect or open the cover with the lower body through attraction and positioning. The lower body of the hair collecting box is the main functional area of ​​the system, which includes the collecting roller and the collecting bag; the collecting roller is installed inside the lower body, and it rolls up the hair scraps and dust on the filter screen by contacting with the filter screen. The rotation of the collecting roller can be mechanically driven or driven by the friction force when the hair collecting box moves. The collecting bag is fixed to a specific position in the lower body through the bag opening, and is usually fixed with a tightening rope or buckle at the bag opening to ensure that the hair scraps can be safely stored in the collecting bag.

[0114] like Figure 3As shown, the hair collecting box is the core component of the cleaning unit. A collecting roller is arranged inside the hair collecting box, which is specially used to clean the hair debris on the filter screen. The collecting roller is installed in the frame of the hair collecting box and can move with the hair collecting box. The collecting roller is fixed at a specific position inside the hair collecting box, and is usually connected to the hair collecting box through a bracket or a bearing. The surface of the roller is provided with bristles or other cleaning elements to enhance its cleaning effect; the collecting roller contacts the surface of the filter screen when the hair collecting box reciprocates, and the hair debris, dust and other debris adhering to the filter screen are rolled into the hair collecting box. The roller can be rotated by mechanical drive or friction drive, so as to effectively collect the debris. The collecting bag is located inside the hair collecting box and is the final collection container for hair debris and debris. It is usually made of soft materials, such as fabric or plastic, to facilitate installation and replacement. The opening of the collection bag is designed with a tightening rope or a fixing device to ensure that the bag opening will not spread out during use. The collection bag is fixed to the corresponding position inside the hair collection box through the tightening device of the bag opening, and can be installed and removed by snaps or other fixing methods. The position of the bag opening is aligned with the entrance of the hair collection box, so that the collection roller can clean the hair scraps into the bag; during the cleaning process, the collection bag is used to save all the hair scraps and debris rolled into the hair collection box by the collection roller. The hair collection box moving seat is used to support the hair collection box and is connected to the synchronous belt to realize its reciprocating motion along the track. The moving seat usually has a guide wheel or a slider to ensure that it moves smoothly along the track.

[0115] The beneficial effects of the above technical solution are: by real-time monitoring and analysis of the movement data of the drum and filter, the system can dynamically adjust the operating parameters to ensure that the equipment operates in the best condition. This refined control significantly improves the cleaning efficiency of the air purification equipment. By analyzing the cleaning result data, the system can identify problems such as filter blockage or abnormal drum speed in advance and generate maintenance suggestions. This reduces the unplanned downtime of the equipment and extends the service life of the equipment. Adjusting the drum speed and filter position according to real-time data helps to optimize the energy consumption of the equipment. For example, when the cleaning demand is low, the system can reduce the drum speed to reduce energy consumption. The implementation of this system improves the automation and intelligence level of air purification equipment. Through real-time data processing and intelligent analysis, the equipment can make adjustments autonomously, reducing dependence on manual operation. By continuously collecting and analyzing equipment operation data, the system can continuously optimize the cleaning effect and equipment performance. This data-driven optimization method can continuously improve the overall performance and user experience of the equipment over time.

[0116] In another embodiment, the full load detection module includes an infrared sensor submodule and a microwave radar sensor submodule;

[0117] The full load detection module detects the full load status of the collection bag, including:

[0118] Obtain the current status information of the collection bag to determine whether it is necessary to detect the full-load status of the hair scraps;

[0119] Control the infrared emitting tube to emit infrared light beams into the collection bag;

[0120] Monitor the intensity of the infrared beam signal received by the infrared receiving tube to determine whether the signal is blocked, wherein the infrared transmitting tube and the receiving tube are controlled to scan the hair debris accumulation area in the collection bag at different angles;

[0121] If the infrared receiving tube does not receive the light beam or the signal strength is lower than a preset threshold, it is determined that the hair debris has reached or exceeded a predetermined amount;

[0122] Based on the signal intensity change of the infrared receiving tube, the accumulation trend of the hair scraps in the collection bag is recorded, and the time point when the hair scraps are fully loaded is predicted;

[0123] and / or,

[0124] The microwave radar transmits and receives signals to detect the density and position changes of the material in the collection bag;

[0125] Using the penetration of microwave radar, the detection results of the infrared sensor module are verified to confirm the accumulation status of dander;

[0126] If the microwave radar sensor module detects a significant change in the signal reflection intensity, it further confirms that the hair debris is fully loaded;

[0127] Based on the signal strength changes of the infrared sensor submodule and / or the microwave radar sensor submodule, the accumulation trend of the hair scraps in the collection bag is recorded, and the time point when the hair scraps are fully loaded is predicted;

[0128] When multiple consecutive signal blocking and / or reflection intensity changes are detected, the full load detection unit is controlled to output a reminder signal to prompt the user to clean the collection bag;

[0129] The signal strength benchmarks of the infrared sensor submodule and microwave radar sensor submodule are recalibrated before each detection to ensure the accuracy and sensitivity of the detection.

[0130] The working principle of the above technical solution is as follows: an infrared transmitting tube, installed on one side of the hair collection box, is used to transmit an infrared light beam to the opposite side of the collection bag; an infrared receiving tube, installed on the other side of the hair collection box opposite to the infrared transmitting tube, is used to receive the infrared light beam from the infrared transmitting tube; a hair debris detection module is used to detect whether the transmission of the infrared light beam is blocked when the hair debris in the collection bag accumulates to a predetermined level; and a reminder module is used to trigger a reminder signal when it is detected that the infrared light beam is blocked by hair debris.

[0131] The infrared transmitting tube and the infrared receiving tube are arranged in such a way that when the hair debris in the collection bag reaches a predetermined amount, the hair debris accumulation area is located exactly between the infrared transmitting tube and the infrared receiving tube, thereby blocking the normal transmission of the infrared light beam. The reminder unit includes an audible and visual alarm, which is used to emit sound and light signals after detecting the blocking of the infrared light beam, reminding the user to clean the hair debris in the collection bag. The hair debris detection unit further includes a processor, which is connected to the infrared receiving tube, processes the received signal to determine whether the infrared light beam is blocked, and controls the reminder unit to trigger the reminder signal when it is determined to be blocked. The processor determines whether the infrared light beam is blocked by comparing the difference between the intensity of the light signal received by the infrared receiving tube and the preset threshold. The infrared transmitting tube and the infrared receiving tube are installed at both ends of the collection bag so that the path of the infrared light beam passes through the hair debris accumulation area of ​​the collection bag.

[0132] The beneficial effects of the above technical solution are as follows: by real-time monitoring of the intensity changes of the infrared signal and multi-angle scanning, the system can more accurately determine the accumulation of dander in the collection bag. This method can effectively avoid misjudgment and improve the working efficiency of the equipment. The system can not only determine the current accumulation status of dander, but also predict the future full load time point. This predictive ability helps users to clean in advance, avoid excessive accumulation of dander, and ensure the normal operation of the air purification equipment. The system realizes full automation of dander accumulation monitoring. Users no longer need to manually check the status of the collection bag. The system will automatically remind when cleaning is needed, which greatly simplifies the operation process. By promptly reminding users to clean the collection bag, the system can prevent equipment damage or blockage caused by excessive dander, thereby extending the service life of the equipment.

[0133] In another embodiment, when a full-load reminder signal is received, an automatic packing and sealing operation is performed on the collection bag, including: obtaining and confirming the full-load reminder signal, and controlling the start of the automatic packing unit;

[0134] The starting mechanism of the closing rope snap-in is triggered, so that the rope of the bag opening is automatically tightened at the snap-in to fix the bag opening;

[0135] At the same time, the soft rubber pressing mechanism on the edge of the bag is activated, so that the soft rubber part is pressed around the mouth of the collection bag to form a preliminary seal;

[0136] Check the sealing status of the bag opening. If the sealing is incomplete, reseal the bag opening through a secondary pressing operation;

[0137] After confirming that the bag mouth is completely sealed, the packaging unit is controlled to cut off the excess closing rope and the end of the rope is fixed by the sealing device to ensure the stability of the seal;

[0138] After the sealing operation is completed, the automatic packaging unit activates the sealing detection device of the bag opening and checks whether the seal is completely sealed by applying a certain pressure. If the test fails, the sealing operation is performed again until the sealing requirement is met;

[0139] The automatic packaging unit includes a cleaning mechanism and an operation indicator for collecting and processing residual materials after the sealing operation is completed. The cleaning mechanism is used to ensure that the working area is clean and free of residue after each packaging operation. The operation indicator is used to display the current operation status and corresponding fault prompts to the user in real time at each step of the packaging process.

[0140] The working principle of the above technical solution is: when the hair and dust in the collection bag reaches a predetermined full load state, the system will send a reminder signal. At this time, the automatic packaging unit starts to work, first confirms the reminder signal, and prepares to start the packaging program. The system triggers the starting mechanism of the closing rope snap-in, so that the rope at the opening of the collection bag is automatically tightened at the snap-in. The purpose of this step is to fix the bag opening to prevent the hair and dust in the bag from leaking.

[0141] As the rope is tightened, the system activates the soft rubber pressing mechanism on the edge of the bag. The soft rubber part is pressed around the mouth of the collection bag to form a preliminary seal. This operation is designed to further ensure that the contents of the bag will not leak out.

[0142] The system detects the sealing status of the bag opening. If it detects that the sealing is incomplete, the system will perform a secondary pressing operation to ensure that the bag opening is completely sealed. The sealing status detection can be completed by a sensor, which will detect the sealing degree of the bag opening and control the pressing force through feedback.

[0143] By detecting the pressure change at the seal, the system can determine whether the seal is complete. If the seal is not tight enough, the pressure will be too low:

[0144]

[0145] Where P is the pressure, F is the applied force, and A is the area of ​​the seal.

[0146] After confirming that the bag mouth is completely sealed, the system controls the packaging unit to cut off the excess closing rope and fix the end of the rope through the sealing device. This operation ensures the stability and durability of the seal.

[0147] After the sealing operation is completed, the automatic packaging unit activates the sealing detection device of the bag opening. The device detects whether the seal is completely sealed by applying a certain pressure. If the test fails, the system will re-execute the sealing operation until the sealing requirement is met. The system determines the degree of sealing by detecting the airtightness of the seal. After packaging is completed, the cleaning mechanism will automatically start to clean up the residual materials to ensure the cleanliness of the work area. The operation indicator shows the user the current operation status and corresponding fault prompts in real time at each step of the packaging process to ensure that the user is aware of the operation of the equipment at any time. The automatic packaging module is designed with a quick-detachable mechanical buckle or magnetic suction device, which makes it easy for users to remove the collection bag full of hair and dust, reducing the complexity of manual operation.

[0148] The beneficial effects of the above technical solution are as follows: the automatic packaging unit realizes the automatic sealing and packaging operation after the collection bag is fully loaded, which greatly improves the working efficiency of the air purification equipment and reduces the frequency of manual intervention; the multiple sealing and sealing detection mechanisms ensure the sealing stability of the collection bag, avoid the leakage of dust and hair in the bag, and maintain the cleanliness of the equipment and the environment; the operation indicator can provide the user with real-time feedback on the operating status of the equipment and possible problems, improve the intelligence of the system, and provide users with a friendly operating experience; the quick disassembly mechanism makes it more convenient to replace a fully loaded collection bag, reduces the maintenance difficulty and time cost of the equipment, and improves the user's experience; the cleaning mechanism ensures that the working area remains clean and residue-free after each packaging operation, avoids secondary pollution, and further improves the cleaning efficiency of the equipment.

[0149] In another embodiment, predicting the time point when the dander is fully loaded includes:

[0150] Acquire the dander signal data in the current collection bag, detect the intensity change of the dander signal through the infrared receiving tube, and output the currently detected signal intensity value;

[0151] Compare the currently detected signal strength value with a preset signal strength threshold value to determine the current accumulation state of hair debris in the collection bag;

[0152] Based on the accumulation state, the accumulation speed of the hair debris in the collection bag is calculated, and the trend of hair debris accumulation is determined;

[0153] According to the accumulation trend of hair dust, the time point when hair dust is fully loaded is predicted and the prediction result is output;

[0154] The steps of predicting the time node of full load of hair scraps are executed cyclically, and the hair scraps accumulation trend and the prediction of the full load time node are updated, until the prediction result reaches the preset accuracy requirement or the collection bag is full.

[0155] The working principle of the above technical solution is: the air purification device detects the dander signal in the collection bag through the internal infrared receiving tube. The presence of dander will affect the intensity of the infrared signal, so the infrared receiving tube can detect the change in signal intensity.

[0156] The signal strength value detected by the infrared receiving tube represents the density of the dandruff. The signal strength value can be expressed as S(t), where t is time.

[0157] The system compares the currently detected signal strength value with the preset signal strength threshold S thresh This threshold represents the lint density standard when the collection bag is close to full.

[0158] Comparison process:

[0159] If S(t)≥S thresh , it means that the lint accumulation in the collection bag is close to or has reached full load.

[0160] Based on the signal strength values ​​at different time points, the system can calculate the accumulation speed v(t) of the hair debris in the collection bag. The accumulation speed can be expressed by the rate of change of the signal strength:

[0161]

[0162] in, is the rate of change of signal strength over time t.

[0163] The system analyzes the accumulated velocity v(t) and accumulated trend of the hair debris. The accumulated trend can be further determined based on the acceleration of the accumulated velocity (i.e. the rate of change of the accumulated velocity):

[0164]

[0165] If the acceleration is positive, it means that the accumulation rate of hair dust is increasing; if it is negative, it means that the accumulation rate is slowing down.

[0166] According to the current accumulation trend and speed of hair dust, the system can predict the time point T when the hair dust is fully loaded. full The prediction formula can be simplified to:

[0167]

[0168] Based on this prediction result, the system outputs the time when the collection bag will be full.

[0169] The system will periodically re-check the signal strength and update the hair debris accumulation speed and trend. By continuously looping the above steps, the system gradually improves the prediction accuracy until the prediction result reaches the preset accuracy requirement or the collection bag is actually full.

[0170] The beneficial effects of the above technical solution are as follows: through real-time monitoring and prediction, the system can accurately determine the accumulation state of the lint in the collection bag. This accuracy not only helps to improve the operating efficiency of the equipment, but also ensures that the collection bag is replaced in time to avoid equipment failure or reduced efficiency due to overfilling of the collection bag; the system can predict the time node when the lint is fully loaded, so that users can arrange maintenance plans in advance, thereby reducing unnecessary inspection and maintenance frequency, improving user experience and equipment utilization; by predicting the accumulation trend and full load time, the system can dynamically adjust the operating parameters of the equipment to further optimize the operation of the equipment. For example, the equipment can adjust the air volume or operating mode when the lint accumulates too quickly to extend the service life of the collection bag. Accurate prediction can avoid replacing the collection bag too early or too late, thereby making full use of the capacity of each collection bag, reducing unnecessary waste and saving costs. The system provides strong data support for the intelligent management of the equipment, enabling the equipment to automatically adjust the operating strategy according to actual usage, enhancing the autonomy and intelligence level of the equipment.

[0171] In another embodiment, a filter screen automatic cleaning method includes:

[0172] Step 1: When the amount of debris on the monitoring filter reaches a preset value, a start signal is obtained to start the drive unit;

[0173] Step 2: Drive the hair collecting box to reciprocate along the set track according to the current driving mode information;

[0174] Step 3: During the reciprocating motion of the hair collecting box, the hair scraps on the filter screen are cleaned into a collection bag provided in the hair collecting box by a collection roller installed on the hair collecting box;

[0175] Step 4: When the hair scraps automatically collected and cleaned in the collection bag reaches a predetermined amount, the full-load detection module detects the full-load state of the hair scraps in the collection bag and triggers a reminder signal;

[0176] Step 5: When a full-load reminder signal is received, the collection bag is automatically packaged and sealed.

[0177] The working principle of the above technical solution is: when the system detects that the accumulation of hair debris on the filter reaches a preset threshold, the system will send a start signal to activate the drive unit, which means that the start of the cleaning process is closely related to the accumulation of hair debris on the filter, ensuring that the cleaning operation is only performed when necessary. According to the current drive mode information, the system controls the hair collection box to reciprocate along the preset track. The setting of the track is usually designed according to the shape and size of the filter to ensure that the hair collection box can effectively cover the entire filter surface. During the reciprocating movement of the hair collection box, the collection roller installed on the hair collection box starts to work. The collection roller contacts the surface of the filter to peel off the accumulated hair debris from the filter and clean it into the collection bag inside the hair collection box. This process ensures that the filter remains clean without affecting the air flow. As the cleaning operation proceeds, the amount of hair debris in the collection bag gradually increases. When the amount of hair debris reaches a predetermined full load state, the system detects this state through a full load detection module and triggers a full load reminder signal, prompting that subsequent processing is required. When the system receives the full load reminder signal, the automation system will pack and seal the collection bag. This step ensures that the hair scraps will not overflow or cause secondary contamination, making it easier to handle or replace them later.

[0178] like Figure 6 As shown, the scraper is located at the lower end of the collection drum and is installed near the starting end. When the hair collection box moves from the starting end to the terminal end of the reciprocating track, the scraper slides along the surface of the filter screen through the precise control of the transmission unit. In this process, the scraper of the scraper will be in close contact with the filter screen to scrape off the hair scraps, dust and other impurities attached to the filter screen; after the scraper passes, the scraped hair scraps and dust are collected into the collection bag below by the collection drum; after the cleaning unit completes the cleaning work, the hair collection box reaches the terminal end of the reciprocating track, at which time, the scraping and hair collection devices will be temporarily disabled, and the entire system enters the return stage; the drive unit reversely drives the hair collection box back to the starting end to prepare for the next round of cleaning operations. In this process, the cleaning unit will transfer the collected hair scraps to the collection box for subsequent processing.

[0179] The beneficial effects of the above technical solution are: by automatically detecting the accumulation of hair debris on the filter and cleaning it in time, the system can maintain the high-efficiency filtering performance of the filter, avoid air flow obstruction caused by hair debris accumulation, and thus improve the efficiency of air purification. The automated design of the system reduces the reliance on manual cleaning and reduces maintenance costs. Operators only need to replace or dispose of the collection bag when prompted by the system, which greatly simplifies daily maintenance work. The automatic packaging and sealing function ensures that hair debris will not be scattered after cleaning, avoiding secondary contamination during the cleaning process. This is especially important in environments with high air quality requirements.

[0180] In another embodiment, obtaining a start signal includes:

[0181] During the operation of the filter, the current lint amount information of the filter is obtained, wherein the current lint amount information includes the current lint accumulation amount of the filter and the cleaning state information of the filter;

[0182] When it is determined based on the current lint amount information that the lint amount of the filter reaches a preset value, a start signal is obtained to start the drive unit, wherein the preset value is used to determine whether the filter needs to perform a drive operation.

[0183] The working principle of the above technical solution is as follows: the system is equipped with sensors for real-time monitoring of the accumulation of lint on the filter. These sensors can detect dust and lint particles on the filter and generate corresponding data signals. The current lint amount information includes two key parts: the current lint accumulation of the filter and the cleaning status information of the filter. The lint accumulation of the filter reflects the actual load of lint on the filter surface, while the cleaning status information provides a status judgment of whether the filter needs to be cleaned. The system compares the real-time monitored lint accumulation with the preset threshold. The preset value is determined by analyzing factors such as the working environment of the equipment, the filter material, and the impact of lint on the filter performance. When the lint amount reaches or exceeds this preset value, the system will consider that the cleaning state of the filter has reached the condition that needs to be cleaned. Once the system confirms that the lint amount on the filter reaches the preset value, it will send a start signal to activate the drive unit. The drive unit will start the filter cleaning system, so that the cleaning device performs a cleaning operation along the filter surface to remove the accumulated lint and restore the filtration efficiency of the filter.

[0184] The beneficial effect of the above technical solution is that by real-time monitoring of the amount of hair debris on the filter and comparing it with the preset value, the system can accurately determine when a cleaning operation is required. This precise judgment of the timing of cleaning avoids unnecessary frequent cleaning operations, prolongs the normal operation time of the equipment, and ensures that the filtering efficiency of the filter will not be reduced due to hair debris accumulation. When the accumulation of hair debris on the filter reaches the preset value, the cleaning operation is started in time to prevent the hair debris from obstructing the air flow and maintain the efficient operation of the air purification system. This helps to continuously provide clean air, especially in places with high environmental requirements, such as hospitals and laboratories. Through intelligent monitoring and control, the system reduces the need for manual intervention, and operators only need to perform maintenance and replacement when necessary. This not only reduces the frequency and cost of manual maintenance, but also reduces the problem of equipment damage or untimely cleaning due to human factors.

[0185] In another embodiment, driving the hair collecting box to reciprocate along a set track includes:

[0186] Acquire the current driving mode information of the driving unit, wherein the current driving mode information includes synchronous wheel and synchronous belt driving information, screw drive driving information, and gear rack drive information;

[0187] When it is determined according to the current driving mode information that the driving unit meets the driving conditions, the corresponding driving mode is selected and executed, and the hair collecting box is driven to reciprocate along the set track by controlling the moving speed and reciprocating frequency of the hair collecting box;

[0188] When the hair collecting box reciprocates along the set track, the operating parameters of the driving mode are monitored and the driving mode is dynamically adjusted according to the operating parameters.

[0189] The working principle of the above technical solution is as follows: the system first obtains the current driving mode information of the drive unit through the sensor and the control unit. This information includes three different driving modes: synchronous wheel and synchronous belt driving information, screw drive driving information, and gear rack drive information. These driving modes are suitable for different operating conditions and requirements. The system will analyze the currently obtained driving mode information and determine whether the driving unit meets the current driving conditions based on factors such as the task requirements, track characteristics, and environmental conditions of the hair collection box. When the driving conditions are met, the system will select the most suitable driving mode. According to the judgment result, the system selects an appropriate driving mode and controls the moving speed and reciprocating frequency of the hair collection box so that it reciprocates along the set track. This movement ensures the effective collection and treatment of hair scraps or dust. During the reciprocating motion of the hair collection box, the system will monitor the operating parameters of the driving mode in real time, such as speed, torque, load conditions, etc. If it is found that the operating parameters deviate from the preset range or the environmental conditions change, the system will dynamically adjust the driving mode to ensure that the hair collection box operates in the best state.

[0190] The beneficial effect of the above technical solution is that by acquiring and analyzing the driving mode information in real time, the system can select the most appropriate driving mode according to the specific operating requirements. This precise driving selection not only improves the operating efficiency of the equipment, but also provides the best performance in different operating scenarios. The moving speed and reciprocating frequency of the hair collection box are controlled and adjusted by the system based on real-time monitoring data to ensure that hair or dust can be effectively collected under various environmental conditions, thereby improving the collection efficiency of the entire air purification system. Since the system can dynamically adjust the driving mode according to the actual operating parameters, it has higher adaptability and can automatically adjust in the face of different environmental conditions or changes in task requirements, thereby improving the stability and reliability of the system.
