Description

Technical Field

[0001] This invention relates to the field of air conditioning unit technology, specifically to a fresh air clean and energy-saving integrated air conditioning unit. Background Technology

[0002] In the prior art, patent document CN220507066U discloses a fresh air clean energy-saving integrated air conditioning unit, including an air conditioning unit and an electrical control cabinet. The electrical control cabinet is located on one side of the air conditioning unit. The air conditioning unit has a partition that divides it into a preliminary filtration zone and a heat exchange filtration zone. The top of the air conditioning unit has a fresh air inlet and an air outlet, located on opposite sides of the partition. The position of the fresh air inlet corresponds to the position of the preliminary filtration zone, and the position of the air outlet corresponds to the position of the heat exchange filtration zone. This unit has high cleanliness performance. The unit uses a specially designed "U"-shaped airflow structure with two stages of filtration in between, resulting in a significant improvement in cleanliness after the airflow passes through the unit. However, the above device has the following technical problems in use:

[0003] Existing air conditioning units have a single filtration mode and cannot dynamically adapt to pollution scenarios. The functional areas of the filter membranes in existing units are mostly fixed, lacking a real-time detection and feedback mechanism for the types of pollutants in the incoming air. It is difficult to dynamically adjust the spatial correspondence of the filter membranes according to actual pollution needs, resulting in a mismatch between filtration effect and energy consumption. The filter membrane usage area is fixed, making it difficult to balance treatment efficiency and lifespan. In units with multiple air outlet ducts, the air flow rate of each air outlet duct is prone to deviation due to differences in duct length and number of bends, and there is a lack of pressure equalization mechanism.

[0004] Based on this, the present invention provides a fresh air clean energy-saving integrated air conditioning unit to solve the problems mentioned in the background art. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a fresh air purification and energy-saving integrated air conditioning unit. This solves the problems of existing air conditioning units having a single filtration mode, being unable to dynamically adapt to pollution scenarios, having fixed filter membrane functional areas, lacking a real-time detection and feedback mechanism for the type of pollutants in the incoming air, making it difficult to dynamically adjust the spatial correspondence of the filter membrane according to actual pollution needs, resulting in a mismatch between filtration effect and energy consumption, and having a fixed filter membrane usage area, making it difficult to balance treatment efficiency and lifespan.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: A fresh air clean energy-saving integrated air conditioning unit includes a casing, an air inlet box installed in the casing, a set of air outlet pipes connected to the top of the air inlet box, and an exhaust box slidably connected to the air inlet box and the casing. The air inlet box is provided with a winding drive module, and the winding drive module is provided with three filter membranes distributed vertically and spaced apart. The surface of each filter membrane is sequentially divided into a dust filtration area, a sterilization area, a purification area and an open area.

[0007] The mode switching system is used to detect the type of pollutants in the airflow of the air inlet box and output control signals to link the winding drive module to adjust the spatial correspondence of each filter membrane, thereby realizing multiple ventilation modes.

[0008] The trajectory control system includes multiple fixed guide roller groups rotatably connected to the air inlet box and multiple moving guide roller groups set on the air outlet box. The trajectory control system drives the air outlet box to move up and down reciprocally and makes the reciprocating stroke and reciprocating frequency of the air outlet box change cyclically in three modes. The trajectory control system adjusts the exposure and usage area of ​​the filter membrane in the air inlet box.

[0009] Two return air systems regulate the number of times the airflow passes through the filter membrane;

[0010] The pressure equalization system balances the airflow from the outlet duct;

[0011] Servo motor, mounted on the housing;

[0012] The synchronous dust filtration system is driven by a servo motor, and after the ventilation mode is locked, it drives the three filter membranes to move synchronously back and forth.

[0013] The beneficial effects of this invention are:

[0014] 1. This invention overcomes the technical bottleneck of fixed and undynamically adjustable filter membrane functional areas in traditional air conditioning units by deeply linking the mode conversion system with the winding drive module. Specifically, the air pollutant acquisition sensor in the mode conversion system detects the pollutant type and filtration effect at the air inlet and outlet in real time. After analysis by the PLC controller, it can precisely control the six conversion motors of the winding drive module to independently adjust the winding state of the main and auxiliary winding rollers of the three filter membranes, so that the dust filtration area, sterilization area, purification area or open area of ​​each filter membrane overlaps or is arranged collaboratively as needed. This closed-loop mechanism of "real-time detection, feedback control, and dynamic membrane adjustment" can intelligently switch the ventilation mode according to the actual pollution scenario, solving the problem of "insufficient filtration in high pollution scenarios and energy waste in low pollution scenarios" caused by the single ventilation mode of traditional units. It achieves a precise match between filtration effect and energy consumption, and has significant intelligence and adaptability compared with the existing technology.

[0015] 2. This invention innovatively integrates a trajectory control system and a synchronous dust filtration system. Through the synergy of the two systems, it achieves dynamic optimization of the filter membrane's usable area and movement state. The trajectory control system drives the lifting frame to rise and fall via an electric actuator. This, combined with the alternating engagement of the three progressively increasing transmission gear segments on the drive wheel and the exhaust box gear plate, ensures that the filter membrane is arranged in a continuous V-shape between the fixed guide roller group and the moving guide roller group. It also cyclically switches the angle through which the fresh air flows, thus expanding the contact area between the filter membrane and the fresh air per unit time and reducing pollutant residue through dynamic movement. The synchronous dust filtration system, after the mode is locked, drives the reciprocating shaft, elastic tension belt, and clutch wheel via a servo motor, causing the three filter membranes to move synchronously back and forth. This ensures that the relative positions of the functional areas are consistent and avoids filtration misalignment caused by single membrane displacement. Compared to the fixed use of filter membranes in traditional units, this invention, through the combined design of adjustable area, dynamic movement, and synchronous coordination, extends the effective filtration cycle of the filter membrane while improving processing efficiency, achieving a highly efficient balance between processing efficiency and lifespan.

[0016] 3. This invention constructs a circular path of "fresh air, primary filtration, return air, and secondary filtration" through the linkage design of the return air system and motorized louvers. Specifically, two return air fans draw in partially processed air between the exhaust box and the second motorized louver through the suction pipe, and then send it back to the bottom of the intake box through the return air pipe. After mixing with fresh air, it flows through the filter membrane again. For high-pollution scenarios, this design can increase the number of times the airflow passes through the filter membrane from 1 time to 2-4 times, significantly improving the filtration effect without increasing the filter membrane area. At the same time, the first motorized louver at the bottom of the casing, the second motorized louver above the exhaust box, and the air cooling module form a short-path integrated airflow, shortening the airflow transmission distance. This not only improves the temperature regulation efficiency of the cooling module, but also reduces energy loss through the coordinated control of the louver opening and closing status and the return air system.

[0017] 4. This invention achieves dynamic equalization of airflow pressure through a pressure equalization system. Specifically, a pressurizing pump pumps the treated air inside the casing into the top air storage chamber. In conjunction with the solenoid valve of the one-way outlet pipe and the airflow sensors of each outlet pipe, the airflow is monitored in real time. When the flow rate in a certain pipe is too low, the PLC controller increases the opening of the corresponding solenoid valve to replenish it with high-pressure air from the air storage chamber; conversely, it decreases the opening. Simultaneously, the pressure probe and temperature probe provide real-time feedback on the air storage chamber status, ensuring that the output airflow pressure remains stable within the set range. This design completely solves the problem of uneven airflow caused by differences in pipe length and the number of bends in traditional units, avoiding increased noise or equipment damage caused by pressure fluctuations. It demonstrates the high stability advantage of an integrated system and provides a reliable guarantee for the simultaneous use of fresh air by multiple devices.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0042] The present invention provides the following preferred embodiments.

[0043] like Figure 1-11As shown, a fresh air clean energy-saving integrated air conditioning unit includes a casing 1 and an air inlet box 2 installed in the casing 1. The top of the air inlet box 2 is connected to a set of air outlet pipes 3.

[0044] The air outlet duct 3 is connected to external fresh air usage equipment or pipelines to achieve fresh air supply;

[0045] Two first motorized louvers 9 are installed on the housing 1 and at the position corresponding to the lower part of the air inlet box 2;

[0046] The first electric louver 9 is used to control whether the housing 1 is exposed to air.

[0047] Two first motorized louvers 9 can precisely control the fresh air intake according to environmental requirements. At the same time, a second motorized louver 10 and an air cooling module 11 are set above the exhaust box 4 from bottom to top, forming an integrated airflow path of "fresh air, first motorized louvers 9, air intake box 2, filter membrane 5 filtration, exhaust box 4, second motorized louvers 10, air cooling module 11, and air outlet duct 3".

[0048] This design solves the problem of long airflow paths and high energy loss caused by the dispersed layout of the air intake, filtration and air cooling modules 11 in traditional air conditioning units. By shortening the airflow transmission distance, it not only improves the temperature regulation efficiency of the air cooling module 11 on the filtered air, but also realizes airflow circulation regulation by linking the opening and closing state of the louvers with the subsequent return air system, effectively reducing the overall energy consumption of the system.

[0049] It also includes an exhaust box 4 that is slidably connected to the air inlet box 2 and the housing 1. The air inlet box 2 is provided with a winding drive module. The winding drive module is provided with three filter membranes 5 that are distributed vertically and spaced apart. The surface of each filter membrane 5 is divided into a dust filtration area 51, a sterilization area 52, a purification area 53 and an open area 54 in sequence.

[0050] An elastic sealing strip is provided at the edge of the filter membrane 5 to ensure the sealing performance when the filter membrane 5 moves;

[0051] The dust filtration zone 51, sterilization zone 52, purification zone 53 and open zone 54 are of the same length;

[0052] The lengths of the dust filtration zone 51, the sterilization zone 52, the purification zone 53, and the open zone 54 are all four times the length of the exhaust cross-section of the exhaust box 4.

[0053] The dust filtration zone 51 is used to filter particulate matter in the air. It is made of glass fiber, polypropylene meltblown cloth or polyester fiber through a hot pressing process. It efficiently captures micron-sized and smaller particles through the interception and inertial collision mechanism formed by the dense fiber pores.

[0054] The sterilization zone 52 is used to remove bacteria and viruses from the air. The sterilization zone 52 is a composite filter containing antibacterial components. Specifically, the sterilization zone 52 is made of polyester fiber with silver ion antibacterial agent loaded on the surface.

[0055] Purification zone 53 is designed to remove odors and harmful gases. Its core material is activated carbon fiber, which decomposes harmful substances through chemical reactions while adsorbing them.

[0056] The function of open area 54 is to allow air to pass through directly;

[0057] The second electric louver 10 and the air cooling module 11 are installed from bottom to top on the inner wall of the housing 1 and above the exhaust box 4.

[0058] Two air pollutant collection sensors 15 are respectively installed between the first electric louver 9 and the air inlet box 2 and between the air cooling module 11 and the air outlet duct 3.

[0059] The air pollutant collection sensor 15 includes a PM2.5 sensor, a VOC sensor, and a microbial sensor;

[0060] The PLC controller 16, PM2.5 sensor, VOC sensor and microbial sensor can all be customized or selected according to actual needs;

[0061] The mode switching system is used to detect the type of pollutants in the airflow of the air inlet box 2 and output control signals to link the winding drive module to adjust the spatial correspondence of each filter membrane 5, so as to realize multiple ventilation modes.

[0062] The winding drive module drives the main winding roller 13 and auxiliary winding roller 14 of the three filter membranes 5 respectively through six conversion motors 12, thereby realizing independent control of the winding state of each filter membrane 5. In conjunction with the two air pollutant acquisition sensors 15 in the mode conversion system to collect data in real time, after analysis by the PLC controller 16, the conversion motors 12 can be linked to adjust the winding state of the filter membrane 5.

[0063] The air pollutant collection sensor 15 at the air inlet detects pollutants in the fresh air, and the air pollutant collection sensor 15 at the air outlet detects the filtration effect.

[0064] The PLC controller 16 uses a PID control algorithm to output pulse signals to control the speed and working status of each conversion motor 12 based on the difference in pollutant concentration between the air pollutant collection sensors 15 at the air inlet and outlet, thereby adjusting the winding state of the filter membrane 5.

[0065] Each conversion motor 12 has a built-in encoder that is connected to the PLC controller 16 for data transmission.

[0066] When the PLC controller 16 determines that the intake airflow needs to undergo a three-stage strong dust filtration mode based on the data feedback from the two air pollutant acquisition sensors 15, the dust filtration areas 51 on the three filter membranes 5 overlap and are all aligned with the exhaust cross section of the exhaust box 4 to achieve three-stage strong dust filtration in the strong dust filtration mode.

[0067] When a three-level strong sterilization mode is required, the sterilization zones 52 on the three filter membranes 5 overlap and are all aligned with the air outlet cross section of the exhaust box 4 to achieve strong sterilization.

[0068] When high-intensity odor removal at three levels is required, the purification zones 53 on the three filter membranes 5 overlap and are all aligned with the exhaust cross-section of the exhaust box 4 to achieve odor removal.

[0069] When only the secondary strong dust filtration mode needs to be achieved, the dust filtration areas 51 on the two bottom filter membranes 5 overlap, and the open area 54 on the top filter membrane 5 corresponds to the dust filtration area 51 on the bottom filter membrane 5.

[0070] When it is necessary to sequentially filter dust, sterilize and deodorize the incoming airflow, the three filter membranes 5 from bottom to top have the following usage areas: dust filtration area 51, sterilization area 52 and purification area 53, respectively.

[0071] Specifically, based on the data feedback from the two air pollutant collection sensors 15, the PLC controller 16 can customize the usage mode of each filter membrane 5 under different parameters to achieve the processing of air intake airflow under different ventilation modes of the air conditioner.

[0072] The PLC controller 16 stores the adjustment parameters of the conversion motor 12 corresponding to various air pollution parameters, thereby realizing the rapid adjustment and mode switching of ventilation mode;

[0073] The dust filtration zone 51, purification zone 53 and sterilization zone 52 on each filter membrane 5 can also be used in turn, thereby achieving uniform wear of multiple filter membranes 5.

[0074] The air cooling module 11 is used to achieve heat exchange and cooling of the air intake airflow in order to regulate the final air outlet temperature of the air outlet duct 3.

[0075] Air cooling module 11 is a commonly used component in existing air conditioning technology, and will not be described in detail here;

[0076] The winding drive module includes six conversion motors 12 installed on the side of the air inlet box 2. Each filter membrane 5 has a main winding roller 13 and a secondary winding roller 14 connected to both ends. The main winding roller 13 and the secondary winding roller 14 are rotatably mounted on the air inlet box 2. Each main winding roller 13 and the secondary winding roller 14 are driven by a corresponding conversion motor 12.

[0077] The mode conversion system includes two air pollutant collection sensors 15 and a PLC controller 16 installed on the end face of the housing 1. The data terminals of the air pollutant collection sensors 15 and the electrical control terminals of the conversion motor 12 are both connected to the PLC controller 16.

[0078] The trajectory control system includes multiple fixed guide roller groups 6 rotatably connected to the air inlet box 2 and multiple moving guide roller groups 7 disposed on the air outlet box 4;

[0079] The fixed guide roller group 6 and the moving guide roller group 7 are arranged alternately in the transverse direction;

[0080] The trajectory control system drives the exhaust box 4 to move up and down reciprocally, and makes the reciprocating stroke and reciprocating frequency of the exhaust box 4 change cyclically in three modes. The trajectory control system adjusts the exposure and usage area of ​​the filter membrane 5 in the air inlet box 2.

[0081] The trajectory control system includes a lifting frame 17. A set of electric push rods 18 is installed between the lifting frame 17 and the air inlet box 2. Multiple limit guide rods 19 are installed on the bottom surface of the exhaust box 4. Each limit guide rod 19 is slidably connected to the lifting frame 17. Each limit guide rod 19 is fitted with a reset spring 20 that is limited by the lifting frame 17.

[0082] A drive wheel 21 is rotatably mounted on the lifting frame 17. The drive wheel 21 is alternately provided with three transmission tooth segments 22 and a toothless reset segment 23. A toothed plate 24 is mounted on the exhaust box 4. The three transmission tooth segments 22 alternately mesh with the toothed plate 24 in a clockwise direction, and the driving stroke of the three transmission tooth segments 22 on the toothed plate 24 increases progressively. Two symmetrically arranged tensioning frames 25 are slidably connected to the air inlet box 2. The sides of the two tensioning frames 25 are each provided with a first tensioning spring 47 that is limited by the housing 1. Tensioning wheels 26 are rotatably mounted on the two tensioning frames 25. The output shaft end of the conversion motor 12 is connected to a first toothed belt. The drive wheel 21 and the two tensioning wheels 26 are both connected to the first toothed belt.

[0083] The driving strokes of the three transmission tooth segments 22 to the tooth plate 24 are 3cm, 6cm and 9cm respectively;

[0084] The center angle and number of teeth corresponding to the effective meshing sections of the three transmission tooth segments 22 increase in a clockwise direction, and the tooth pitch on the effective meshing sections of the three transmission tooth segments 22 is the same.

[0085] The trajectory control system also includes two follower frames 27 that are slidably connected to the air inlet box 2. Each follower frame 27 is rotatably mounted with a follower roller group 28. Both follower roller groups 28 are in contact with the filter membrane 5. Each follower frame 27 has a set of second tension springs 29 that are limited by the air inlet box 2 installed on its top surface.

[0086] The trajectory control system drives the lifting frame 17 to rise and fall via the electric push rod 18. In conjunction with the alternating meshing of the three transmission gear segments 22 on the drive wheel 21 with the toothed plate 24 of the exhaust box 4, the exhaust box 4 produces an increasing reciprocating movement in the vertical direction.

[0087] Simultaneously, the elastic compensation between the tensioning frame 25, the first tensioning spring 47, and the second tensioning spring 29 ensures that the filter membrane 5 remains under tension between the fixed guide roller group 6, the moving guide roller group 7, and the follower roller group 28. This design allows for dynamic adjustment of the unfolded area of ​​the filter membrane 5 according to the filtration mode.

[0088] When performing strong dust filtration, strong sterilization, or strong odor removal, the opening area of ​​the filter membrane 5 on the roller can be adjusted by adjusting the distance between the lifting frame 17 and the air inlet box 2. After the filter membrane 5 is unfolded, the filter membrane 5 can be arranged in a continuous V shape by setting the arrangement of the fixed guide roller group 6 and the moving guide roller group 7, thereby adjusting the filtration effect of the filter membrane 5 on the air and the contact area between the air and the filter membrane 5, and thus adjusting the air treatment efficiency and treatment intensity of the filter membrane 5.

[0089] When the filter membrane 5 is in operation, the filter membrane 5 changes through three reciprocating strokes and corresponding reciprocating frequencies. Through the generation of the above changes, on the one hand, the angle of the core air flowing through the filter membrane 5 is changed in a cycle, thereby improving the efficiency of the fresh air flowing through the filter membrane 5 and increasing the contact area between the fresh air and the filter membrane 5 per unit time. On the other hand, the dynamic movement of the filter membrane 5 can reduce the residual rate of pollutants in the fresh air on the filter membrane 5, thereby maintaining the filtration performance of the filter membrane 5.

[0090] Servo motor 8 is mounted on housing 1;

[0091] Two return air systems regulate the number of times the airflow passes through filter membrane 5;

[0092] The synchronous dust filtration system is driven by a servo motor 8, which drives the three filter membranes 5 to move synchronously back and forth after the ventilation mode is locked.

[0093] Each return air system includes a return air fan 30 installed inside the housing 1. The air inlet of the return air fan 30 is connected to an air suction pipe 31. The air suction pipe 31 is connected to the inner cavity of the housing 1 at the position between the corresponding second electric louver 10 and the exhaust box 4. The air outlet of the return air fan 30 is connected to a return air pipe 32. The return air pipe 32 is connected to the inner cavity of the housing 1 at the position below the corresponding air inlet box 2.

[0094] Each return air system draws in partially processed air between the exhaust box 4 and the second motorized louver 10 through the return air fan 30, then through the suction pipe 31, and then through the return air pipe 32 back to the bottom of the air inlet box 2. After mixing with the fresh air, the air flows through the filter membrane 5 again, forming a circulation path of fresh air, primary filtration, return air, and secondary filtration. For high-pollution scenarios, this design can increase the number of times the airflow passes through the filter membrane 5 from 1 time to 2-4 times, thereby achieving the circulation treatment of fresh air.

[0095] The pressure equalization system balances the airflow from the outlet duct 3;

[0096] The pressure equalization system includes an air storage chamber 41 located at the top of the housing 1. A pressurizing pump 42 is installed at the top of the housing 1. The air inlet of the pressurizing pump 42 is connected to the inner cavity of the housing 1, and the air outlet of the pressurizing pump 42 is connected to the air storage chamber 41. Each air outlet pipe 3 is connected to the air storage chamber 41 by a one-way air outlet pipe 43. A solenoid valve is installed in the one-way air outlet pipe 43. A one-way exhaust valve and an airflow sensor 44 are installed on each air outlet pipe 3. A pressure probe 45 for monitoring the internal pressure of the air storage chamber 41 and a temperature probe 46 for monitoring the internal temperature of the air storage chamber 41 are installed on the housing 1. The electronic control terminal of the solenoid valve, the data terminals of the airflow sensor 44, the pressure probe 45 and the temperature probe 46 are all connected to the PLC controller 16.

[0097] The pressure equalization system pumps the processed air inside the casing 1 into the air storage chamber 41 at the top through the pressurization pump 42. It works with the solenoid valve of the one-way air outlet pipe 43 and the airflow sensor 44 of the air outlet pipe 3 to monitor the air flow rate of each air outlet pipe 3 in real time.

[0098] When the flow rate of any air outlet duct 3 is low, the PLC controller 16 controls the corresponding solenoid valve to increase the opening degree, and the high-pressure air in the air storage chamber 41 is replenished to the duct. Conversely, the opening degree is reduced. At the same time, the air pressure probe 45 and the temperature probe 46 provide real-time feedback on the status of the air storage chamber 41 to ensure that the output airflow pressure is stable within the set range.

[0099] This design solves the problem of uneven air output caused by differences in duct length and number of bends in multi-duct 3 systems, ensuring the stable operation of fresh air equipment and avoiding increased noise or equipment damage caused by pressure fluctuations, demonstrating the stability advantages of an integrated system.

[0100] The synchronous dust filtration system includes a second toothed belt, a third toothed belt, and a dual-head motor 33 mounted on the air inlet box 2. Tensioning screws 34 are driven to the two output shaft ends of the dual-head motor 33. Each tensioning screw 34 has a threaded section with opposite helical directions and the same pitch. A clutch frame 35 is driven to the two tensioning screws 34, and a clutch wheel 36 is rotatably mounted on each of the two clutch frames 35. One clutch wheel 36 and three main rollers 13 are connected to the second toothed belt, and the other clutch wheel 36 and three auxiliary rollers 14 are connected to the third toothed belt. A reciprocating shaft 37, driven by a servo motor 8 and rotating within a set cycle, is rotatably mounted on the air inlet box 2. An elastic tension belt 38 is driven to the reciprocating shaft 37, and both clutch wheels 36 are driven to the elastic tension belt 38.

[0101] A pinion 39 is mounted on the reciprocating shaft 37. A torsion spring 48 is provided at the rotational connection between the reciprocating shaft 37 and the air inlet box 2. A half-tooth ring 40 is mounted on the output shaft end of the servo motor 8. The half-tooth ring 40 is connected to the pinion 39 for transmission. The elastic tension belt 38 is made of rubber and elastically compensates for the displacement of the clutch wheel 36 through pre-tensioning force.

[0102] After the ventilation mode of the filter membrane 5 is defined, the spacing between the two clutches 35 is set so that the second and third toothed belts are kept in a fully tensioned state, thereby ensuring that the three main rollers 13 and the three auxiliary rollers 14 can move synchronously.

[0103] After the ventilation mode of filter membrane 5 is limited, the conversion motor 12 is in an idle state. The conversion motor 12 does not have a power-off self-locking function and can run idle in the power-off state.

[0104] When the filter membrane 5 is in ventilation mode adjustment state, the two clutches 35 move further apart, and the second and third toothed belts remain in a relaxed state. The three main rollers 13 and the three auxiliary rollers 14 lose their linkage state, and each conversion motor 12 can drive the main rollers 13 and auxiliary rollers 14 at the corresponding positions to operate with the set parameters.

[0105] After the ventilation mode is locked, the functional areas of the three filter membranes 5 have been adjusted to an overlapping or collaborative working state by the winding drive module. The synchronous reciprocating movement can ensure that the functional areas of each filter membrane 5 always maintain the same relative position, avoid misalignment of the filtration area due to the displacement of a single filter membrane 5, thereby stably maintaining the set filtration mode and ensuring the continuity and reliability of the filtration effect.

[0106] When the filter membrane 5 moves back and forth synchronously, it dynamically changes the angle and contact position of the fresh air flowing through the filter membrane 5. Compared with the fixed filter membrane 5, this dynamic movement can make the contact area between the fresh air and the filter membrane 5 larger and more uniform per unit time, avoiding local areas from becoming saturated quickly due to continuous contact, thereby improving the treatment efficiency of fresh air.

[0107] Synchronous reciprocating movement can reduce the residual rate of particulate matter and microbial pollutants in fresh air on the surface of filter membrane 5 through mechanical vibration effect;

[0108] Dynamic movement can reduce the adhesion and accumulation of pollutants, delay the clogging of filter membrane 5, extend its effective filtration cycle, and reduce the cost of frequent replacement of filter membrane 5.

[0109] By combining the reciprocating stroke and frequency changes of the trajectory control system, synchronous movement can evenly utilize the functional area of ​​filter membrane 5 within the set stroke.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
