Description

Technical Field

[0001] This utility model is a vehicle filter cartridge with a dust removal detection device, belonging to the technical field of environmentally friendly vehicle accessories. Background Technology

[0002] In urban road cleaning operations, especially in dry or dusty environments, integrated sweeping and vacuuming vehicles have increasingly become core equipment for urban environmental sanitation maintenance as modern sanitation equipment. These vehicles collect road dust and garbage using negative pressure suction, playing an irreplaceable role in urban dust control and refined cleaning. With rising environmental standards and increasing demands for refined urban management, higher requirements are being placed on the performance of the filtration system in vacuuming equipment. As a key filtration component, the filter cartridge's working condition directly determines the overall vacuuming efficiency and operational quality of the vehicle.

[0003] In traditional integrated sweeping and vacuuming vehicles, the filter cartridge cleaning system makes it impossible for operators to monitor the dust accumulation inside the filter cartridge in real time and accurately. Due to the lack of effective monitoring methods, operators often fail to notice when dust accumulation on the filter cartridge surface reaches a critical point. Relying solely on timing or experience to determine the timing of cleaning is insufficient and cannot be dynamically adjusted according to actual working conditions, resulting in two extreme situations: "not cleaning when it should be cleaned" or "over-cleaning".

[0004] When the filter cartridge becomes clogged, the airflow at the garbage bin's air inlet is obstructed, causing the vehicle's negative pressure system to malfunction and significantly reducing dust collection efficiency. In cases of severe clogging, forced cleaning can easily result in uneven dust shedding from the filter cartridge surface, leading to secondary dust pollution. Operators are unaware of the dust conditions inside the filter cartridge and cannot promptly detect problems with the garbage bin's air chamber sealing or abnormal operation of the auxiliary engine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car filter cartridge with a dust removal detection device to solve the problems of the existing technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A vehicle filter cartridge with a dust removal detection device includes: a vehicle compartment, a filter chamber disposed in the vehicle compartment and a garbage bin air chamber, and a first air pressure monitoring component disposed in the garbage bin air chamber;

[0008] The second air pressure monitoring component is installed in the filter chamber. The filter chamber is equipped with a partition, and a through hole is opened on the partition. An auxiliary frame is installed on the through hole. The filter cartridge is inserted and fixed in the auxiliary frame, with the protruding side of the filter cartridge facing the air chamber of the garbage bin.

[0009] The vibration assembly installed on the auxiliary frame flips the air blowing mechanism set on the partition. Before the filter cartridge is installed, the air blowing mechanism is flipped to make room. After the filter cartridge is installed, the air blowing mechanism is flipped, and part of the air blowing mechanism is inserted into the middle of the filter cartridge.

[0010] It also includes a control module, which is electrically connected to the vibration component, the air blowing mechanism, the first air pressure monitoring component, and the second air pressure monitoring component;

[0011] The first air pressure monitoring component monitors the air pressure inside the garbage bin, and the second air pressure monitoring component monitors the air pressure inside the garbage filter.

[0012] When the air pressure in the garbage bin chamber drops below a preset value, and the air pressure in the filter chamber rises above a preset value, the control module controls the vibration component to transmit high-frequency oscillations toward the filter cartridge, and simultaneously controls the air blowing mechanism to blow high-pressure gas into the filter cartridge to clear blockages on the outer layer of the filter cartridge and unclog the filter holes.

[0013] As a further improvement, the air blowing mechanism includes a support frame rotatably mounted on the side of the partition, an air blowing pipe disposed in the middle of the support frame, an exhaust port disposed on the side of the air blowing pipe, and the air blowing pipe being connected to an external fan through an air supply pipe.

[0014] As a further improvement, the air blowing mechanism also includes a first driving component for driving the support frame to rotate. The first driving component is fixedly mounted on the partition and electrically connected to the control module. The control module controls the first driving component to drive the support frame to rotate, so that the end of the air blowing pipe with the exhaust port is inserted into the filter cartridge. The first driving component is a motor.

[0015] As a further improvement, the air blowing mechanism also includes a second drive assembly fixed on the support frame, which controls the lifting and lowering of the air blowing pipe. The second drive assembly is an electric guide rod, and the air blowing pipe is fixedly installed at the end of the electric guide rod.

[0016] As a further improvement, the auxiliary frame is provided with a mounting groove, the vibration component includes a support base, a positioning protrusion is provided on one side of the support base corresponding to the mounting groove, a slot is provided in the middle of the support base, a vibration motor is fixedly installed in the through hole, the vibration motor is electrically connected to the control module, the control module controls the vibration of the vibration motor to vibrate, and the vibration is transmitted to the filter cartridge through the auxiliary frame, which works in conjunction with the air blowing pipe to synchronously remove dust and clean the filter cartridge.

[0017] As a further improvement, an air pump is also included, which is electrically connected to the control module and is located in the chassis.

[0018] As a further improvement, it further includes a buzzer arranged in the cab, the buzzer is electrically connected with the control module, and when the air pressure in the dustbin air chamber decreases beyond a preset value and the air pressure in the filter chamber rises beyond a preset value, the buzzer is controlled to start by the control module.

[0019] As a further improvement, it further includes a display screen arranged in the cab, the display screen is electrically connected with the control module, and the display screen displays the monitored air pressure data of the dustbin air chamber and the filter chamber.

[0020] Beneficial effects:

[0021] In this utility model, the first and second air pressure monitoring assemblies are respectively arranged in the dustbin air chamber and the filter chamber to form a "negative pressure - positive pressure" dual-parameter comparative monitoring mechanism. The detected air pressure value of the dustbin air chamber is P1, the detected air pressure value of the filter chamber is Q1, and the set air pressure value of the dustbin air chamber is obtained through a large number of tests under normal working conditions, and the absolute value of the set comparison value of the air pressure in the dustbin air chamber is set as P0;

[0022] The set air pressure value of the filter chamber is obtained through a large number of tests under normal working conditions, and the absolute value of the set comparison value of the air pressure in the filter chamber is set as Q0;

[0023] When the air pressure in the dustbin air chamber decreases beyond the preset value (P1<P0) and the air pressure in the filter chamber rises beyond the preset value (Q1>Q0), the control module accurately identifies the blocked state of the filter cartridge, and synchronously activates the vibration assembly and the air blowing mechanism to realize the cooperative dust cleaning operation of high-frequency oscillation and high-pressure air flow.

[0024] After the vehicle enters the working state, the air pressure monitoring assembly continuously collects data and transmits it to the control module. The control module compares the air pressure parameters in real time through a preset algorithm, and conducts accurate analysis and judgment in the form of absolute values by combining the non-negative pressure characteristic of the filter cartridge chamber and the negative pressure characteristic of the dustbin air chamber. When the system detects a filter cartridge clogging trend, the operation display screen immediately displays the corresponding alarm level to guide the operator to take targeted measures.

[0025] The core advantage of this design lies in the realization of closed-loop control of "monitoring-judgment-response": the high-frequency oscillation generated by the vibration assembly loosens the dust on the surface of the filter cartridge, and the air blowing mechanism is accurately inserted into the middle part of the filter cartridge for directional purging, and the synergistic effect of the two significantly improves the dust cleaning efficiency. The innovative design of the auxiliary frame and the flip-type air blowing mechanism ensures the convenience of filter cartridge installation and the accuracy of dust cleaning operations, and avoids the problem of incomplete dust cleaning caused by inaccurate positioning in the traditional dust cleaning process.

[0026] Furthermore, a three-tiered intelligent alarm mechanism can be implemented: a level 1 alarm prompts a check for the airtightness of the waste bin; a level 2 alarm indicates that filter cartridge cleaning can be performed; and a level 3 alarm mandates immediate cleaning and a check of system integrity. This tiered response strategy transforms the cleaning operation from experience-based to data-driven, effectively avoiding the industry pain points of "not cleaning when it should" and "over-cleaning".

[0027] Compared to traditional dust removal systems, this solution represents a technological leap from passive response to proactive prevention. Existing technologies rely solely on timed dust removal or operator experience, failing to accurately assess the actual degree of filter cartridge blockage. This system, however, establishes a scientific dust removal triggering mechanism through dynamic comparison of air pressure parameters in two zones. Correlation analysis of air pressure between the garbage bin's air chamber and the filter cartridge chamber not only accurately determines the filter cartridge's blockage status but also simultaneously monitors system sealing and auxiliary engine operating status, achieving a comprehensive diagnosis of the equipment's health.

[0028] Regarding dust removal efficiency, traditional systems using only air blowing for dust removal often result in uneven dust shedding. This solution, however, combines vibration and air blowing to ensure uniform dust removal from the filter cartridge surface, significantly reducing the risk of secondary dust generation. The intelligent tiered alarm mechanism allows operators to take precise interventions based on system status, preventing both delayed dust removal leading to decreased system efficiency and excessive dust removal causing energy waste and filter cartridge wear, thus significantly improving equipment operating efficiency and lifespan.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0039] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] Reference Figure 1-7As shown, a vehicle filter cartridge 9 with a dust cleaning detection device comprises: a carriage 1, a filter chamber 2 and a dustbin air chamber 3 arranged in the carriage 1, and a first air pressure monitoring assembly 4 arranged in the dustbin air chamber 3;

[0041] A second air pressure monitoring assembly 5 arranged in the filter chamber 2, a partition plate 21 is arranged in the filter chamber 2, a through hole 22 is formed in the partition plate 21, an auxiliary frame 23 is mounted on the through hole 22, the filter cartridge 9 is inserted and fixed in the auxiliary frame 23, and the protruding side of the filter cartridge 9 faces the dustbin air chamber 3 side;

[0042] A vibration assembly 24 mounted on the auxiliary frame 23, and an air blowing mechanism 25 arranged on the partition plate 21 in a turnover manner, wherein the air blowing mechanism 25 is turned over to give way before the filter cartridge 9 is mounted, and after the filter cartridge 9 is mounted, the air blowing mechanism is turned over, and part of the air blowing mechanism is inserted into the middle part of the filter cartridge 9;

[0043] The device further comprises a control module 6, wherein the control module 6 is electrically connected with the vibration assembly 24, the air blowing mechanism 25, the first air pressure monitoring assembly 4 and the second air pressure monitoring assembly 5;

[0044] The air pressure in the dustbin air chamber 3 is monitored by the first air pressure monitoring assembly 4, and the air pressure in the filter chamber 2 is monitored by the second air pressure monitoring assembly 5;

[0045] When the air pressure in the dustbin air chamber 3 decreases beyond a preset value and the air pressure in the filter chamber 2 rises beyond a preset value, the control module 6 controls the vibration assembly 24 to transmit high-frequency oscillation to the filter cartridge 9, and synchronously controls the air blowing mechanism 25 to blow high-pressure gas into the filter cartridge 9, so as to clean the blockages on the outer layer of the filter cartridge 9 and dredge the filter holes.

[0046] By arranging the first and second air pressure monitoring assemblies 5 in the dustbin air chamber 3 and the filter chamber 2 respectively, a "negative pressure - positive pressure" dual-parameter comparative monitoring mechanism is formed. For the detected air pressure value P1 of the dustbin air chamber 3 and the detected air pressure value Q1 of the filter chamber 2, the set air pressure value of the dustbin air chamber 3 is obtained through a large number of tests under normal working conditions, and the absolute value of the set comparison value of the air pressure of the dustbin air chamber 3 is set as P0;

[0047] The set air pressure value of the filter chamber 2 is obtained through a large number of tests under normal working conditions, and the absolute value of the set comparison value of the air pressure of the filter chamber 2 is set as Q0;

[0048] When the air pressure in the dustbin air chamber 3 decreases beyond the preset value (P1<P0) and the air pressure in the filter chamber 2 rises beyond the preset value (Q1>Q0), the control module 6 accurately identifies the blocking state of the filter cartridge 9, synchronously activates the vibration assembly 24 and the air blowing mechanism 25, and realizes the cooperative dust cleaning operation of high-frequency oscillation and high-pressure air flow.

[0049] Once the vehicle is in operation, the air pressure monitoring component continuously collects data and transmits it to the control module 6. The control module 6 compares the air pressure parameters in real time using a preset algorithm, combining the non-negative pressure characteristics of the filter cartridge 9 chamber with the negative pressure characteristics of the garbage bin's air chamber 3, and performs precise analysis and judgment in absolute value form. When the system detects a clogging trend in the filter cartridge 9, the operation display screen 8 immediately displays the corresponding alarm level, guiding the operator to take targeted measures.

[0050] The core advantage of this design lies in achieving closed-loop control of "monitoring-judgment-response": the high-frequency vibration generated by the vibration component 24 loosens the dust on the surface of the filter cartridge 9, and the air blowing mechanism 25 is precisely inserted into the middle of the filter cartridge 9 for directional blowing. The synergistic effect of the two significantly improves the dust removal efficiency. The innovative design of the auxiliary frame 23 and the flip-type air blowing mechanism 25 ensures the ease of installation of the filter cartridge 9 and the accuracy of the dust removal operation, avoiding the problem of incomplete dust removal caused by inaccurate positioning in traditional dust removal processes.

[0051] Furthermore, a three-tiered intelligent alarm mechanism can be implemented: a level 1 alarm prompts a check of the trash can's airtightness; a level 2 alarm indicates that filter cartridge 9 cleaning can be performed; and a level 3 alarm mandates immediate cleaning and a check of system integrity. This tiered response strategy transforms the cleaning operation from experience-dependent to data-driven, effectively avoiding the industry pain points of "not cleaning when it should" and "over-cleaning".

[0052] Compared to traditional dust removal systems, this solution represents a technological leap from passive response to proactive prevention. Existing technologies rely solely on timed dust removal or operator experience, failing to accurately assess the actual degree of blockage in filter cartridge 9. This system, however, establishes a scientific dust removal triggering mechanism through dynamic comparison of air pressure parameters across two zones. Correlation analysis of the air pressure between the garbage bin's air chamber 3 and the filter cartridge 9 chamber not only accurately determines the blockage status of filter cartridge 9 but also simultaneously monitors system sealing and the auxiliary engine's operating status, achieving a comprehensive diagnosis of the equipment's health.

[0053] Regarding dust removal efficiency, traditional systems using only air blowing for dust removal are prone to uneven dust shedding. This solution, however, combines vibration and air blowing to ensure uniform dust shedding from the filter cartridge 9 surface, significantly reducing the risk of secondary dust generation. The intelligent tiered alarm mechanism allows operators to take precise interventions based on system status, preventing both delayed dust removal leading to decreased system efficiency and excessive dust removal causing energy waste and filter cartridge 9 wear, thus significantly improving equipment operating efficiency and lifespan.

[0054] The first air pressure monitoring assembly 4 is essentially an air pressure transmitter installed in the air chamber 3 of the garbage bin, configured to monitor the air pressure state in the air inlet area of the garbage bin in real time. This assembly adopts high-precision negative pressure sensing technology, which can accurately capture tiny air pressure changes in the air chamber 3 of the garbage bin. Under the normal working state of the vehicle, due to the suction effect of the fan 254, the air chamber 3 of the garbage bin presents a stable negative pressure state, and this assembly continuously monitors and transmits air pressure data to the control module 6.

[0055] The special value of this monitoring assembly lies in its ability to accurately reflect the sealing performance of the garbage bin system and the working efficiency of the fan 254. When the air pressure in the air chamber 3 of the garbage bin decreases beyond the preset value (P1<P0), it indicates that there may be poor sealing of the system or abnormal operation of the fan 254, which directly affects the dust collection efficiency of the entire vehicle. The monitoring data is transmitted in the form of absolute values, which facilitates precise analysis and judgment by the control module 6.

[0056] The second air pressure monitoring assembly 5 is an air pressure transmitter installed in the filter chamber 2, specially configured to monitor the air pressure state of the surrounding environment of the filter cartridge 9. Different from the air chamber 3 of the garbage bin, the filter chamber 2 is in a non-negative pressure working state, and the air pressure value is approximately equal to the atmospheric pressure value under normal conditions. This assembly adopts high-sensitivity atmospheric pressure monitoring technology, which can timely capture subtle air pressure changes caused by dust accumulation on the surface of the filter cartridge 9.

[0057] As a further improvement, the air blowing mechanism 25 includes a support frame 251 rotatably mounted on the side surface of the partition plate 21, and an air blowing pipe 252 arranged in the middle of the support frame 251. An air outlet 253 is arranged on the side surface of the air blowing pipe 252, and the air blowing pipe 252 communicates with the external fan 254 through an air delivery pipe 2541.

[0058] The air blowing mechanism 25 further includes a first driving assembly 255 that drives the support frame 251 to rotate. The first driving assembly 255 is fixedly mounted on the partition plate 21 and is electrically connected to the control module 6. The control module 6 controls the first driving assembly 255 to drive the support frame 251 to rotate, so as to insert the end of the air blowing pipe 252 with the air outlet 253 into the filter cartridge 9. The first driving assembly 255 is a motor 2551.

[0059] The air blowing mechanism further includes a second driving assembly 256 fixed on the support frame 251. The second driving assembly 256 controls the air blowing pipe 252 to move up and down. The second driving assembly 256 is an electric guide rod 2561, and the air blowing pipe 252 is fixedly mounted at the end of the electric guide rod 2561.

[0060] The air blowing mechanism 25 adopts a multi-degree-of-freedom precision control structure, which consists of a rotating support frame 251, a height-adjustable air blowing pipe 252 and a dual-drive system. The support frame 251 is rotatably mounted on the side of the partition plate 21, and the air blowing pipe 252 with a lateral exhaust port 253 is arranged in the middle part, which communicates with the external fan 254 through the air delivery pipe 2541. The first drive assembly 255 adopts a high-precision motor 2551, which is fixed on the partition plate 21 and communicates with the control module 6 in real time to realize precise angle control of the support frame 251. The second drive assembly 256 adopts an electric guide rod 2561, which is fixed on the support frame 251, and the air blowing pipe 252 is mounted at the end to realize precise positioning in the vertical direction.

[0061] The problem of space conflict between the air blowing mechanism 25 and the filter cartridge 9 during installation in the traditional dust cleaning system is solved. The rotating design of the support frame 251 allows the air blowing pipe 252 to completely give way when the filter cartridge 9 is installed, and automatically reset after the installation is completed, avoiding positioning errors caused by manual adjustment. The introduction of the dual-drive system realizes three-dimensional precise control of the dust cleaning position, breaking through the limitation of the traditional fixed air blowing mechanism 25 that can only perform dust cleaning at a single position.

[0062] During operation, when the air pressure monitoring assembly detects that the pressure in the garbage bin air chamber 3 decreases (P1<P0) and the pressure in the filter chamber 2 increases (Q1>Q0), the control module 6 automatically starts the dust cleaning procedure. The first drive assembly 255 first drives the support frame 251 to rotate, so as to precisely position the air blowing pipe 252 at the central axis position of the filter cartridge 9, ensuring that the air blowing direction is consistent with the axial direction of the filter cartridge 9. Subsequently, the second drive assembly 256 controls the electric guide rod 2561 to drive the air blowing pipe 252 to descend, and automatically adjusts to the optimal dust cleaning height according to the clogging degree of the filter cartridge 9.

[0063] Through the design of the lateral exhaust port 253, the high-pressure air flow impacts the inner wall of the filter cartridge 9 in a tangential direction, forming a spirally rising air flow and a lateral impact air flow, which effectively impacts the filter holes frequently, and effectively avoids the dust "accumulation effect" caused by traditional axial purging. Combined with the high-frequency oscillation of the vibration assembly 24, the dust on the surface of the filter cartridge 9 falls off uniformly, which greatly improves the dust cleaning efficiency. After the dust cleaning is completed, the system resets automatically, the air blowing pipe 252 rotates to give way and rises to the standby position, reserving sufficient operating space for possible subsequent replacement of the filter cartridge 9.

[0064] The precision and adaptability of dust cleaning operations are significantly improved. The rotating mechanism solves the space conflict between the installation of the filter cartridge 9 and the dust cleaning equipment, making equipment maintenance more convenient; the height-adjustable air blowing pipe 252 can adjust the dust cleaning strategy according to different clogging degrees, adopting local dust cleaning for mild clogging and full-process dust cleaning for severe clogging, avoiding energy waste. The cooperative operation of the dual-drive system ensures the optimal action angle between the dust cleaning air flow and the surface of the filter cartridge 9, which increases the dust cleaning efficiency by more than 40%, and minimizes the risk of secondary dust emission at the same time.

[0065] In actual operation, the operator only needs to confirm the system alarm level through the display screen 8, and the system will automatically complete the positioning and dust cleaning work of the air blowing mechanism 25, which greatly reduces the operation difficulty and the risk of human error. This structure transforms the dust cleaning of the filter cartridge 9 from extensive operation to precise and intelligent operation, effectively prolongs the service life of the filter cartridge 9, and ensures the continuous and efficient operation capability of the integrated washing, sweeping and dust collection vehicle.

[0066] The auxiliary frame 23 is provided with a mounting groove 241, the vibration assembly 24 includes a support base 242, a positioning protrusion 243 is provided on one side of the support base 242 corresponding to the mounting groove 241, a slot hole 244 is provided in the middle of the support base 242, a vibration motor 246 is fixedly installed in the through hole 22, the vibration motor 246 is electrically connected to the control module 6, the vibration of the vibration motor 246 is controlled by the control module 6, and the vibration sensation is transmitted to the filter cartridge 9 through the auxiliary frame 23, so as to perform dust removal and cleaning on the filter cartridge 9 synchronously in cooperation with the air blowing pipe 252.

[0067] The vibration assembly 24 adopts a precise positioning transmission mechanism, the auxiliary frame 23 is provided with a special mounting groove 241, and the support base 242 is provided with a positioning protrusion 243 at the corresponding position to ensure the close fit between the two. A slot hole 244 is opened in the middle of the support base 242, and the vibration motor 246 is directly installed in the through hole 22, forming an efficient energy transmission path of "motor 2551 - support base 242 - auxiliary frame 23 - filter cartridge 9". This structure solves the technical problem that the dust on the surface of the filter cartridge 9 is tightly attached and difficult to remove. The mechanical vibration loosens the dust layer on the surface of the filter cartridge 9, creating favorable conditions for the subsequent air blowing dust cleaning.

[0068] The precise fit design of the positioning protrusion 243 and the mounting groove 241 ensures the efficient transmission of vibration force, and avoids the energy loss caused by the loose connection of the traditional external vibration device. The vibration motor 246 is directly installed in the through hole 22, which shortens the energy transmission distance, makes the vibration frequency and amplitude more stable and controllable, and effectively prevents the problem of incomplete local dust cleaning of the filter cartridge 9 caused by uneven vibration.

[0069] During the operation of the system, when the air pressure monitoring component detects that the pressure of the garbage bin air chamber 3 decreases (P1<P0) and the pressure of the filtering chamber 2 increases (Q1>Q0), the control module 6 starts the vibration motor 246 and the air blowing mechanism 25 synchronously. The vibration motor 246 generates high-frequency vibration, which is accurately transmitted to the auxiliary frame 23 through the positioning protrusion 243 of the support base 242, and then transmitted to the body of the filter cartridge 9. The filter cartridge 9 generates micro-deformation under the action of vibration, so that the dust layer attached to the surface cracks and loosens.

[0070] Simultaneously, the air blowing mechanism 25 delivers high-pressure gas into the filter cartridge 9, causing loose dust to quickly detach from its surface under the influence of the airflow. The synergistic effect of vibration and air blowing improves the dust removal efficiency by over 60% compared to traditional single-air blowing methods, especially for dust with high humidity and strong adhesion. This mechanism effectively avoids the problem of decreased filter cartridge 9 efficiency due to incomplete dust removal, while also reducing the risk of damage to the filter cartridge 9 structure caused by high-pressure air blowing.

[0071] In daily operation, operators do not need to manually intervene in the dust removal process. When the system detects a clogging trend in the filter cartridge 9, the display screen 8 automatically displays the corresponding alarm level. After a level two or three alarm is triggered, the control module 6 automatically starts the vibration motor 246 to generate vibration at a set frequency, with the duration automatically adjusted according to the degree of clogging. During the vibration, the dust on the surface of the filter cartridge 9 is evenly loosened, and in conjunction with the directional airflow of the blowing mechanism 25, efficient dust removal is achieved.

[0072] After dust removal is completed, the vibration motor 246 automatically stops working, and the system resets to monitoring mode. This structure transforms the maintenance of the filter cartridge 9 from a rough operation to a precise task, significantly reducing the labor intensity of operators, while extending the service life of the filter cartridge 9 and ensuring the continuous and efficient operation of the sweeper and vacuum cleaner.

[0073] It also includes an air pump 245 installed in the frame, which is electrically connected to the control module 6.

[0074] As a further improvement, a buzzer 7 is also included in the cab. The buzzer 7 is electrically connected to the control module 6. When the air pressure in the garbage bin air chamber 3 drops below a preset value, and when the air pressure in the filter chamber 2 rises above a preset value, the buzzer 7 is activated by the control module 6. A display screen 8 is also included in the cab. The display screen 8 is electrically connected to the control module 6 and displays the monitored air pressure data in the garbage bin air chamber 3 and filter chamber 2.

[0075] The air pump 245, serving as the power source for the dust removal system, is directly installed in the vehicle frame structure and electrically connected to the control module 6. This configuration solves the technical problem of unstable air supply in traditional dust removal systems, ensuring a continuous and stable supply of high-pressure gas. The power and flow rate of the air pump 245 are precisely calculated to meet the air pressure requirements for cleaning the filter cartridge 9 under different operating conditions, avoiding incomplete cleaning due to insufficient air supply.

[0076] The buzzer 7 and display screen 8 integrated in the cab form a complete operation feedback system. The buzzer 7 automatically activates in the three-level alarm state, providing immediate audible warnings; the display screen 8 displays the precise air pressure data of the garbage bin air chamber 3 and filter chamber 2 in real time, allowing operators to intuitively grasp the system's operating status. This combined sound and light warning mechanism effectively solves the industry pain point of operators' inaccurate judgment of the filter cartridge 9's blockage status.

[0077] The display screen 8 accurately displays the air pressure monitoring value in digital form, and simultaneously indicates the alarm levels with different colors: a level one alarm displays a yellow warning, prompting the operator to check the airtightness of the garbage bin; a level two alarm displays an orange warning, indicating that the filter cartridge 9 can be cleaned; a level three alarm displays a red warning and activates the buzzer 7, forcing immediate cleaning. The air pump 245 automatically starts after the level three alarm is triggered, providing a high-pressure air source to the air blowing mechanism 25 to ensure timely and effective cleaning operations.

[0078] During daily operations, operators can immediately understand the working status of the filter cartridge 9 by observing the air pressure data and alarm indicators on the display screen 8. When a level one alarm appears on the display screen 8, the sealing of the garbage bin and the working status of the auxiliary engine should be checked; when a level two alarm appears, the dust removal program can be started through the control panel; when a level three alarm appears, the system automatically starts the air pump 245 and the dust removal device, while the buzzer 7 continuously sounds to remind the operator to handle the situation immediately.

[0079] The automatic start-stop mechanism of air pump 245 ensures efficient energy use, providing power only when dust removal is needed, thus avoiding energy waste caused by the continuous operation of air pump 245 in traditional systems. The precise air pressure data on display screen 8 also provides important reference for equipment maintenance, enabling operators to predict the lifespan of filter cartridge 9 based on historical data trends and achieve preventative maintenance.
