Description

Technical Field

[0002] With the acceleration of industrialization and urbanization, cars have become an important means of daily travel for people, and the air quality inside them has also received attention. Traditional filters have limitations in filtering effect and service life, and cannot meet the high requirements of modern cars for air quality. As the use time of traditional filters increases, more impurities are attached to the filter element, affecting normal use, and the filter element needs to be replaced regularly.

[0003] The patent with announcement number CN112727641B discloses a dust-proof automobile filter, which forms a three-layer filtering device by arranging a first filter screen, a second filter screen, and a third filter screen, and the filter screen openings are successively reduced to achieve layer-by-layer filtering of dust and impurities in the air, and a filter protection shell push-pull disassembly device is formed by arranging a filter protection shell, an air inlet, a push-pull plate, a filter element, a track, a pulley, and a cleaning brush. The push-pull plate can resist a certain amount of dust in the air, and the use of the internal filter can also be checked through its transparent material. The cleaning brush can clean the outer surface of the filter element while retracting the push-pull plate, reducing the replacement frequency of the filter element and greatly improving the utilization rate of the filter.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 12As shown: an automobile air filter with dust-proof function, comprising a filter body 1 and an air inlet 2, an air inlet structure 3, a dual-channel dust removal mechanism and a dust collecting structure 8; the air inlet structure 3 comprises a three-way pipe 31 and two opening and closing structures 32, the middle part of the three-way pipe 31 is connected to the air inlet 2, the two opening and closing structures 32 are respectively arranged at the two ends of the three-way pipe 31, the opening and closing structure 32 comprises a three-way joint 321, an opening and closing plate 322 and a linear driver 323, the three connecting ends of the three-way joint 321 are respectively connected to the three-way pipe 31, the dust removal structure 5 and the dust collecting structure 8, the opening and closing plate 322 is arranged in the three-way pipe 31, the linear driver 323 is arranged on one side of the three-way joint 321, and the linear driver 323 is connected to the opening and closing plate 322 The dual-channel dust removal mechanism includes a chassis 4, two dust removal structures 5, a vibration structure 6 and an air outlet control structure 7. A first mounting bin 41 is provided on both sides of the chassis 4, and a second mounting bin 42 is provided in the middle of the chassis 4. The two dust removal structures 5 are respectively arranged in the two first mounting bins 41, and the two dust removal structures 5 are respectively connected to the two opening and closing structures 32. The vibration structure 6 is arranged in the second mounting bin 42, and the vibration structure 6 is connected to the two dust removal structures 5. The air outlet control structure 7 is arranged at one end of the chassis 4, and the air outlet control structure 7 is connected to the ends of the two dust removal structures 5, and the air outlet control structure 7 is also connected to the filter body 1; the dust collecting structure 8 is arranged at the other end of the chassis 4, and the dust collecting structure 8 is connected to the two opening and closing structures 32.

[0035] During the operation of the dust-proof air filter for automobiles, after the filter body 1 is started, the two opening and closing structures 32 act synchronously to open the two ends of the three-way pipe 31, so that after the airflow enters the three-way pipe 31 from the air inlet 2, the airflow is evenly distributed to the two dust removal structures 5. The two dust removal structures 5 independently perform preliminary dust removal on the airflow, and the two airflows that have undergone dust removal converge at the air outlet control structure 7 and are finally introduced into the filter body 1. The air is filtered again in the filter body 1 to complete the normal air filtration process. When the dust accumulated on the surface of any dust removal structure 5 reaches a certain level, an opening and closing structure 32 closes its corresponding three-way pipe 31 port, and at the same time the air outlet control structure 7 temporarily blocks the air to the filter body 1. Flow channel, then, the airflow continues to enter through the unclosed port of the three-way pipe 31, and flows through the dust removal structure 5 that is still involved in the dust removal work, and then the airflow turns to flow through another dust removal structure 5 that is not involved in the dust removal. In this process, the power generated by the airflow prompts the dust on the dust removal structure 5 to move toward the dust collecting structure 8, and is finally collected in the dust collecting structure 8. As the dust is removed, the states of the two opening and closing structures 32 are interchanged to ensure that the two dust removal structures 5 can take turns to self-clean and maintain efficient dust removal performance. Through the synergistic effect of the dual-channel dust removal mechanism and the opening and closing structure 32, the alternating cleaning of the dust removal structure 5 is achieved, which effectively avoids the decrease in dust removal efficiency caused by dust accumulation and ensures that the filter body 1 continues to operate efficiently.

[0036] Reference Figure 3 , Figure 4 and Figure 5 As shown: the dust removal structure 5 includes a dust removal box 51 and two dust removal components 52; the dust removal box 51 includes a rectangular box 511 and a cover plate 512, both ends of the rectangular box 511 are provided with external interfaces, the two external interfaces are respectively connected to the opening and closing structure 32 and the air outlet control structure 7, and the cover plate 512 is covered at the opening of the rectangular box 511; the two dust removal components 52 are arranged on the cover plate 512, and are symmetrically arranged about the middle surface of the cover plate 512, and the dust removal effect of the dust removal component 52 close to the air outlet control structure 7 is stronger than that of the dust removal component 52 close to the opening and closing structure 32.

[0037] The dust removal component 52 with a stronger dust removal effect is set as the first dust removal component 52, and the dust removal component 52 with a weaker dust removal effect is set as the second dust removal component 52. During the operation of the filter body 1, the airflow is first introduced through the three-way pipe 31, and then flows in from an external interface of the rectangular box 511. The airflow passes through the second dust removal component 52 and the first dust removal component 52 in turn to achieve a step-by-step dust removal effect, that is, it is first preliminarily purified by the second dust removal component 52 with a slightly weaker dust removal effect, and then deeply purified by the first dust removal component 52 with a stronger dust removal effect. When the dust removal structure 5 needs to be maintained and cleaned, the airflow path is reversed and passes through the first dust removal component 52 and the second dust removal component 52 in turn. In this process, the dust accumulated on the first dust removal component 52 is carried to the second dust removal component 52 with the airflow. Since the dust was originally carried by the airflow passing through the second dust removal component 52, the dust can pass through the second dust removal component 52 again, thereby effectively improving the dust removal efficiency and self-cleaning ability of the dust removal structure 5.

[0038] Reference Figure 5 and Figure 6 As shown: the dust removal assembly 52 includes a docking shaft 521, a docking sleeve 522 and a filter screen 523; the docking shaft 521 is parallel to the cover plate 512, and one end of the docking shaft 521 is fixedly connected to the cover plate 512; the docking sleeve 522 is sleeved on the docking shaft 521, and one end of the docking sleeve 522 is connected to the vibration structure 6; the filter screen 523 is arranged on the docking sleeve 522.

[0039] During the self-cleaning process of the dust removal structure 5, the vibration structure 6 will participate in it and drive the two dust removal structures 5 to vibrate at the same time. If the dust removal component 52 in the dust removal structure 5 vibrates in a direction perpendicular to the airflow, a gap will be generated between the dust removal component 52 participating in filtering the airflow and the rectangular box 511, resulting in the airflow entering the self-cleaning dust removal structure 5 without being filtered. The dust removal structure 5 cannot achieve self-cleaning. Therefore, the vibration direction of the dust removal component 52 needs to be controlled in a direction parallel to the airflow flow. The vibration generated by the vibration structure 6 is transmitted to the docking sleeve 522. Since a sliding connection is adopted between the docking sleeve 522 and the docking shaft 521, the docking shaft 521 effectively limits the vibration direction of the filter screen 523. Therefore, the docking sleeve 522 drives the filter screen 523 to move back and forth along the docking shaft 521. During this process, the filter screen 523 can always maintain a close fit with the inner wall of the rectangular box 511, thereby effectively preventing unfiltered airflow from entering the self-cleaning dust removal structure 5.

[0040] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown: the vibration structure 6 includes two vibration transmission components 61 and a driving structure 62; the two vibration transmission components 61 correspond to the two dust removal structures 5 respectively, the vibration transmission component 61 includes a telescopic shaft 611, a transmission block 612 and two connecting shafts 613, one end of the telescopic shaft 611 extends from the second mounting bin 42 into the first mounting bin 41, the middle part of the transmission block 612 is connected to the end of the telescopic shaft 611, and two slide grooves 6121 are provided on the transmission block 612, the two slide grooves 6121 are symmetrical about the telescopic shaft 611 and inclined toward the end of the telescopic shaft 611, the two connecting shafts 613 are respectively slidably arranged in the two slide grooves 6121, and the two connecting shafts 613 are respectively connected to the ends of the docking sleeves 522 in the two dust removal components 52; the driving structure 62 is arranged between the two vibration transmission components 61, and the driving structure 62 is connected to the two vibration transmission components 61.

[0041] In the self-cleaning stage of the dust removal structure 5, the driving structure 62 is started to drive the two vibration transmission components 61 to work. As the telescopic shaft 611 telescopes, the transmission block 612 moves under the guidance of the telescopic shaft 611. When the transmission block 612 moves toward the middle position of the two docking sleeves 522, due to the inclined design of the two slide grooves 6121, the two connecting shafts 613 are pushed by the transmission block 612, forcing the two connecting shafts 613 to move closer to each other, thereby driving the two docking sleeves 522 to move closer to each other. On the contrary, when the telescopic shaft When 611 drives the transmission block 612 away from the docking sleeve 522, the inclined design of the slide groove 6121 causes the two connecting shafts 613 to be pulled away from each other, pushing the two docking sleeves 522 to separate from each other, and the telescopic shaft 611 is driven by the driving structure 62 to reciprocate along its axial direction. This alternating approach and distance action causes the two filters 523 to vibrate back and forth along the corresponding docking shafts 521, making it easier for dust attached to the surface of the filter 523 to fall off, thereby enhancing the cleaning effect of the filter 523.

[0042] Reference Figure 7 and Figure 8 As shown in the figure: the driving structure 62 includes a driving block 621, two driving plates 622, a reciprocating driving assembly 623 and a guide assembly 624; the driving block 621 is arranged in parallel between the two telescopic shafts 611; the two driving plates 622 are respectively arranged at both ends of the driving block 621, and the two ends of the driving plate 622 are respectively axially connected to the end of the driving block 621 and the end of the telescopic shaft 611; the reciprocating driving assembly 623 is arranged on one side of the driving block 621 and is connected to the middle part of the driving block 621, and the reciprocating driving assembly 623 includes a first rotating driver 6231, a short swing arm 6232 and a long swing arm 6233, and the first rotating driver The device 6231 is arranged in the second installation bin 42, one end of the short swing arm 6232 is connected to the first rotation driver 6231, and the two ends of the long swing arm 6233 are respectively connected to the end of the short swing arm 6232 and the middle axis of the driving block 621; the guide assembly 624 is arranged on the other side of the driving block 621, and the guide assembly 624 includes a fixed sleeve 6241 and a guide rod 6242, the fixed sleeve 6241 is arranged in the second installation bin 42, the guide rod 6242 is slidably arranged in the fixed sleeve 6241, and the guide rod 6242 is perpendicular to the telescopic shaft 611, and one end of the guide rod 6242 is connected to the driving block 621.

[0043] When the driving structure 62 is started, the reciprocating driving assembly 623 starts to work, and the first rotary driver 6231 drives the short swing arm 6232 to rotate. The rotational motion of the short swing arm 6232 is converted into the reciprocating motion of the driving block 621 through the lever action of the long swing arm 6233. At the same time, the guide rod 6242 in the guide assembly 624 can only slide along its own axis under the constraint of the fixed sleeve 6241, ensuring that the driving block 621 reciprocates along the axial direction of the guide rod 6242. With the movement of the driving block 621, when the driving block 621 approaches the two telescopic shafts 611, the two driving plates 622 push the two telescopic shafts 611 away from each other, and when the driving block 621 moves away from the two telescopic shafts 611, the two driving plates 622 pull the two telescopic shafts 611 closer to each other. The driving plates 622 alternately move away and closer, thereby realizing the reciprocating motion of the telescopic shaft 611, thereby driving the vibration of the dust removal structure 5.

[0044] Reference Figure 6 As shown: the dust removal assembly 52 also includes a first spring 524, which is arranged between the end of the docking shaft 521 and the end of the docking sleeve 522, and the two ends of the first spring 524 are respectively connected to the end of the docking shaft 521 and the end of the docking sleeve 522.

[0045] When the two telescopic shafts 611 approach each other, the angle between the telescopic shaft 611 and the driving plate 622 gradually increases, and the force acting on the telescopic shaft 611 in the direction parallel to its axis gradually decreases, resulting in a decrease in the force acting on the telescopic shaft 611 when the two telescopic shafts 611 are pushed away from each other. By setting a first spring 524 between the end of the docking shaft 521 and the end of the docking sleeve 522, in the process of the two telescopic shafts 611 approaching each other, the first spring 524 is compressed and stores elastic potential energy. When it is necessary to drive the two telescopic shafts 611 away from each other, the first spring 524 releases its stored elastic potential energy and pushes the docking sleeve 522 to move in the direction of the docking shaft 521. In the process of the movement of the docking sleeve 522, the connecting shaft 613 cooperates with the sliding groove 6121 on the transmission block 612 to drive the connecting shaft 613 to move in the direction between the two docking sleeves 522, thereby ensuring that the two telescopic shafts 611 can obtain a larger driving force in the process of moving away from each other.

[0046] Reference Figure 3 and Fig. 9 As shown: the air outlet control structure 7 includes an air outlet pipe 71 and a first solenoid valve 72; the middle part of the air outlet pipe 71 is connected to the filter body 1, and the two ends of the air outlet pipe 71 are respectively connected to the external interfaces of the two rectangular boxes 511; the first solenoid valve 72 is arranged between the air outlet pipe 71 and the filter body 1.

[0047] When the dust removal structure 5 is performing self-cleaning, if the path of the airflow to the filter body 1 is not closed, a large amount of airflow will flow to the filter body 1, resulting in less airflow flowing to the self-cleaning dust removal structure 5, affecting the self-cleaning effect of the dust removal structure 5. Therefore, a first solenoid valve 72 is arranged between the air outlet pipe 71 and the filter body 1. When the filter body 1 is working normally, the first solenoid valve 72 remains open, allowing the airflow filtered by the filter to flow smoothly to the filter body 1. When the dust removal structure 5 starts the self-cleaning function, the first solenoid valve 72 is closed to cut off the path of the airflow to the filter body 1, and the airflow originally flowing to the filter body 1 is completely guided to the dust removal structure 5 that is undergoing self-cleaning, ensuring that the dust removal structure 5 can obtain sufficient airflow support, thereby greatly improving the self-cleaning effect.

[0048] Reference Figure 3 and Fig.10 As shown: the dust collecting structure 8 includes a dust collecting pipe 81, two second solenoid valves 82 and a dust collecting chamber 83; the dust collecting pipe 81 is arranged between the two opening and closing structures 32, and the two ends of the dust collecting pipe 81 are respectively connected to the two opening and closing structures 32; the two second solenoid valves 82 are respectively arranged at the two ends of the dust collecting pipe 81, and the second solenoid valves 82 are located between the dust collecting pipe 81 and the opening and closing structures 32; the open end of the dust collecting chamber 83 is connected to the middle part of the dust collecting pipe 81, the dust collecting chamber 83 is cylindrical, and a plurality of exhaust filters 831 are arranged on the side wall of the dust collecting chamber 83.

[0049] When the dust removal structure 5 is performing self-cleaning, the second solenoid valve 82 close to the dust removal structure 5 will open, while the other second solenoid valve 82 will close. This action ensures that one end of the dust collecting pipe 81 is only connected to the dust removal structure 5 that is performing self-cleaning. Subsequently, the airflow will be filtered or cleaned by the dust removal structure 5 and enter the dust collecting chamber 83. In the dust collecting chamber 83, the airflow will be discharged smoothly through the exhaust filter 831 on the side wall, and the dust will be retained in the dust collecting chamber 83 due to the blocking effect of the exhaust filter 831. The dust in the dust collecting chamber 83 will continue to be squeezed by the subsequent incoming airflow, thereby gathering in the dust collecting chamber 83, which is convenient for subsequent cleaning and processing.

[0050] Reference Fig.10 and Fig.11 As shown: the dust collecting structure 8 also includes a cleaning structure 84, which includes a rotating shaft 841 and a plurality of cleaning arm assemblies 842; one end of the rotating shaft 841 is connected to the middle of the dust collecting tube 81 through a bearing, and the other end of the rotating shaft 841 extends out of the dust collecting tube 81; a plurality of cleaning arm assemblies 842 are arranged at the other end of the rotating shaft 841.

[0051] During operation, the airflow is discharged from the dust collecting bin through the exhaust filter 831. During this process, the dust carried by the airflow is intercepted by the exhaust filter 831 and adheres to the exhaust filter 831. However, the accumulation of dust will hinder the smooth discharge of the airflow and affect the dust collection efficiency. For this purpose, a cleaning structure 84 is provided. When the rotating shaft 841 rotates, its power is transmitted to a plurality of cleaning arm assemblies 842, driving the plurality of cleaning arm assemblies 842 to rotate simultaneously. The cleaning arm assemblies 842 move inside the dust collecting bin to clean the exhaust filter 831 and effectively remove the dust attached thereto, thereby ensuring the continuous permeability of the exhaust filter 831 and maintaining efficient airflow discharge capability.

[0052] Reference Fig.11 and Fig.12 As shown: the cleaning arm assembly 842 includes a fixed arm 8421, a telescopic arm 8422, a second spring 8423 and a cleaning brush 8424; the fixed arm 8421 is connected to the rotating shaft 841, and the fixed arm 8421 is perpendicular to the rotating shaft 841; one end of the telescopic arm 8422 is slidably set inside the fixed arm 8421; the second spring 8423 is sleeved on the telescopic arm 8422, and the two ends of the second spring 8423 are respectively abutted against the ends of the fixed arm 8421 and the telescopic arm 8422; the cleaning brush 8424 is set at the other end of the telescopic arm 8422.

[0053] In the initial non-working state, the telescopic arm 8422 remains in a retracted state due to the elastic force of the second spring 8423 and is stored inside the fixed arm 8421. At this time, the cleaning brush 8424 maintains a certain distance from the exhaust filter 831. When the rotating shaft 841 starts to rotate, driving the multiple cleaning arm assemblies 842 to rotate together, the cleaning brush 8424 will overcome the elastic force of the second spring 8423 due to the action of centrifugal force, driving the telescopic arm 8422 to slide and extend along the inside of the fixed arm 8421 until the cleaning brush 8424 can fit tightly on the exhaust filter 831. During this process, the second spring 8423 is gradually compressed to store elastic potential energy. As the cleaning arm assembly 842 continues to rotate, the cleaning brush 8424 reaches a dynamic balance between the centrifugal force and the elastic force of the second spring 8423, maintaining close contact with the exhaust filter 831 and effective cleaning. When the cleaning arm assembly 842 rotates to an area where the centrifugal action is weakened, the second spring 8423 releases the stored elastic potential energy, pushing the telescopic arm 8422 to drive the cleaning brush 8424 to reset, preparing for the next cleaning action. Through the combined action of centrifugal force and spring force, the cleaning brush 8424 can fit tightly against the exhaust filter 831, thereby effectively removing dust attached to the surface of the exhaust filter 831 and improving the cleaning efficiency and effect.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
