Description

Technical Field

[0001] The invention relates to the technical field of air filtration, and in particular to an air filter assembly of an air compressor. Background Art

[0002] Air compressors are devices that compress and store air. They play an important role in industrial production. Air compressors are mainly composed of electric motors, compressors, and air tanks. When the motor is started, it drives the compressor to start running. During the operation, air in the atmosphere is sucked into the compressor and undergoes multi-stage compression processing to eventually reach the required high-pressure state. Subsequently, the high-pressure gas is sent to the air tank for storage. The air filter assembly in the air compressor is a key part of the air compressor. Its main function is to filter the air entering the air compressor and remove dust and impurities therein, thereby improving the quality of the compressed air of the air compressor and making it more in line with the requirements of industrial production.

[0003] At present, traditional air filter components in air compressors are mostly composed of a shell, a barrel cover and a filter element. However, the filter element is mostly fixed in the shell, that is, the filter element will not rotate or move after being installed in the shell. This fixed state limits the full contact between the filter element and the air, making the impurities on the surface of the filter element unevenly distributed. Specifically, when impurities in the air are sucked into the shell from the air inlet end of the shell and contact the filter element, since the filter element is fixed and the air circulation path in the shell is also fixed, impurities may accumulate in a local area of ​​the filter element, and eventually the filter element will be locally blocked and overloaded, thereby accelerating the loss of the service life of the filter element.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the air filter assembly of the air compressor, by starting the driving motor, the driving motor drives the driving gear to rotate through the connecting column. When the driving gear rotates, it meshes with the outer edge of the gear ring, so that the gear ring drives the connecting seat to rotate synchronously. When the connecting seat rotates, it will synchronously drive the filter element clamped and fixed by the L-shaped clamp to rotate synchronously, so that the filter element can be more fully in contact with the air, and the dust and impurities in the air are more evenly distributed on the filter element, avoiding the situation where the filter element is partially blocked and overloaded due to excessive accumulation of impurities in a certain area of ​​the filter element.

[0027] 2. In the air filter assembly of the air compressor, when the connecting seat rotates, the ends of the two clamping columns will be driven to move along the inner side of the oblique groove. When the clamping column moves to collide with the inclined surface on the inner side of the oblique groove, the mounting shell will be driven to move along the outer side of the connecting pipe toward the fixed plate, so that the inner side of the mounting shell can squeeze the folded airbag, compress the internal space of the folded airbag, and then make the internal airflow of the folded airbag enter the blowing pipe B from the blowing pipe A, and then blow air from the ports of multiple one-way blowing ends through the blowing pipe B toward the inner side of the filter element for cleaning, so as to remove the tiny particles and impurities that clog the filter element, thereby extending the service life of the filter element.

[0028] 3. In the air filter assembly of the air compressor, while the mounting shell is reciprocating, the connecting frame is also pushed to move synchronously along the inner side of the limit groove B. In the process of the connecting frame moving toward the push frame, the beveled surfaces of the two beveled blocks at both ends of the push frame will collide with each other, so that the push frame is subjected to force and then moves down along the inner sides of the two slides. While the push frame is moving downward, the arc plate is driven to move downward synchronously through the fixed frame A, so that the arc plate hits the inner side of the filter element, and the filter element vibrates when impacted, so that impurities attached to the surface of the filter element fall off, thereby avoiding excessive accumulation of impurities and clogging of the filter element, thereby further enhancing the service life of the filter element and enabling the filter element to maintain good filtering performance for a long time.

[0049] The connection mechanism 7 includes a connection seat 701, a tooth ring 702 is arranged on the outer side of the connection seat 701, a plurality of hinge seats 703 are arranged on the inner side of the connection seat 701, the ends of the plurality of hinge seats 703 are hinged with L-shaped clamping members 704, the outer walls of the L-shaped clamping members 704 are provided with limiting grooves A705, the inner sides of the limiting grooves A705 are hinged with hinges 706, and an annular plate 707 is arranged between the outer walls of the plurality of hinges 706, the annular plate 707 is used to position the installation of the filter element 3, and can drive the L-shaped clamping members 704 to clamp and fix the filter element 3 under the pressure of the filter element 3;

[0050] The inner wall of the connection seat 701 is symmetrically fixed with two clamping columns 7011, and the inner side of the connection seat 701 is provided with a plurality of key slots 7012, the inner sides of the plurality of key slots 7012 are all engaged with the protrusions on the inner side of the annular plate 707, and a support spring 7013 is connected between one side of the annular plate 707 and the inner side of the connection seat 701;

[0051] The keyway 7012 is used to limit the sliding distance of the annular plate 707 along the connecting seat 701;

[0052] The support spring 7013 is used to provide a force for the annular plate 707 to reset when the filter element 3 is separated from the connecting mechanism 7;

[0053] The inner walls of the housing A1 and the housing B4 are both rotatably connected to the outer wall of the connecting seat 701, and a fixing frame B9 is fixedly connected between the outer sides of the housing A1 and the housing B4;

[0054] A mounting base 10 is fixedly connected to the outer side of the shell A1, a driving motor 11 is installed on the inner side of the mounting base 10, a connecting column 12 is fixedly connected to the output shaft of the driving motor 11, a driving gear 13 is fixedly connected to the outer wall of the connecting column 12, and the outer edge of the driving gear 13 is meshed with the outer edge of the gear ring 702, and the end of the connecting column 12 is rotatably connected to a mounting plate 14, and the bottom of the mounting plate 14 is fixedly connected to the outer side of the shell B4.

[0055] In this embodiment, when pressure is applied to the annular plate 707 at the end of the filter element 3, the inner side of the annular plate 707 will move along the inner side of the key groove 7012. At this time, the multiple support springs 7013 will all be subjected to the force from the annular plate 707, thereby causing the support springs 7013 to be compressed. When the annular plate 707 is moved under force, the multiple hinges 706 will be driven to slide adaptively along the inner side of the limit groove A705, thereby causing the multiple L-shaped clamps 704 to be hinged to the multiple hinge seats 703, respectively. In this way, the clamping parts at one end of the multiple L-shaped clamps 704 can clamp and fix the outer side of the filter element 3, and then the drive motor 11 is started to turn on the drive motor 11. The driving gear 13 is driven to rotate by the connecting column 12. When the driving gear 13 rotates, it meshes with the outer edge of the gear ring 702, thereby causing the gear ring 702 to drive the connecting seat 701 to rotate synchronously. The fixing frame B9 provided between the outer sides of the outer shell A1 and the outer shell B4 is used to ensure that the outer shell A1 and the outer shell B4 can always remain fixed. When the connecting seat 701 rotates, it will synchronously drive the filter element 3 clamped and fixed by the L-shaped clamp 704 to rotate synchronously, so that the filter element 3 can be more comprehensively in contact with the air, so that the dust and impurities in the air are more evenly distributed on the filter element 3, avoiding the situation where the filter element 3 is partially blocked and overloaded due to excessive accumulation of impurities in a certain area of ​​the filter element 3.

[0056] In this embodiment, Figure 4 , Fig. 9 , Fig.10 , Fig.11 and Fig.16 As shown, the dust cleaning mechanism 6 can blow air toward the inner side of the filter element 3 for cleaning under the driving force of the connection mechanism 7 to rotate;

[0057] The dust cleaning mechanism 6 includes a connecting pipe 601, a mounting shell 602, a fixing plate 603, a one-way air inlet valve 604 and two air blowing pipes A605. The outer side of the connecting pipe 601 is fixedly connected to the inner side of the fixing plate 603. A folding air bag 606 is fixedly connected between one side of the fixing plate 603 and the inner side of the mounting shell 602. The one-way air inlet valve 604 and one side end of the two air blowing pipes A605 penetrate the inner wall of the fixing plate 603 and are connected to the folding air bag 606. The other ends of the two air blowing pipes A605 are connected to the air blowing pipe B607, and the air blowing pipe B607 is connected to a plurality of one-way air blowing ends 608.

[0058] The inner wall of the mounting shell 602 is slidably connected with a plurality of limit rods 6021, one end of each of the limit rods 6021 is fixedly connected to one end of the fixing plate 603, one side of the fixing plate 603 is connected with a plurality of return springs 6022, one end of each of the return springs 6022 is fixedly connected to the inner side of the mounting shell 602, and a plurality of oblique grooves 6023 are formed at the end of the mounting shell 602;

[0059] The return spring 6022 is used to exert a force on the mounting shell 602 to move along the outer side of the connecting tube 601, so as to push the outer edge of the oblique groove 6023 to always fit with the end of the clamping column 7011;

[0060] The oblique groove 6023 can enable the mounting shell 602 to drive the folding airbag 606 to adaptively reciprocate along the outer side of the connecting tube 601 under the movement of the clamping column 7011;

[0061] Both ends of the air blowing pipe B607 are fixedly connected to support plates 6071 , and the outer sides of the support plates 6071 are fixedly connected to the outer sides of the support frame 501 .

[0062] In this embodiment, when the connecting seat 701 rotates, the ends of the two clamping columns 7011 are driven to move along the inner side of the oblique groove 6023. When the clamping column 7011 moves to conflict with the inclined surface of the inner side of the oblique groove 6023, the mounting shell 602 is driven to move along the outer side of the connecting pipe 601 toward the fixed plate 603, so that the inner side of the mounting shell 602 can squeeze the folded airbag 606, so that the internal space of the folded airbag 606 is compressed, and then the internal airflow of the folded airbag 606 enters the blowing pipe B607 from the blowing pipe A605, and then blows air from the ports of multiple one-way blowing ends 608 toward the inner side of the filter element 3 through the blowing pipe B607 for cleaning, so as to remove the tiny particles and impurities that clog and adhere to the filter element 3, thereby extending the service life of the filter element 3, and while the mounting shell 602 moves It will be limited by multiple limit rods 6021 to ensure the stability of the installation shell 602 when it moves, and multiple return springs 6022 will be pressed by the installation shell 602 and then shrink. After the clamping column 7011 moves out of the inclined surface inside the oblique groove 6023 during the rotation, it falls back into the inclined surface inside the oblique groove 6023. Through the elastic force of the return spring 6022, the installation shell 602 can be pushed, so that the inclined surface inside the oblique groove 6023 can intermittently fit with the end of the clamping column 7011. When the end of the clamping column 7011 fits with the inclined surface of the oblique groove 6023 again, the installation shell 602 will drive the folding airbag 606 to expand, so that the folding airbag 606 draws air through the one-way air inlet valve 604, thereby replenishing the internal gas of the folding airbag 606 for the next blowing cleaning work.

[0063] In this embodiment, Figure 4 , Fig. 9 , Fig.12 , Fig.13 and Fig.14 As shown, the beating mechanism 5 can be driven by the rotation of the connecting mechanism 7 to beat the inner side of the filter element 3;

[0064] The beating mechanism 5 includes a support frame 501 and a fixed frame A502. A limiting groove B503 is provided on one side of the support frame 501. Two slide seats 504 are provided on the inner side of the support frame 501. A push frame 505 is slidably connected between the inner sides of the two slide seats 504. The bottom end of the push frame 505 is fixedly connected to the outer side of the fixed frame A502. The bottom end of the fixed frame A502 is provided with an arc plate 506.

[0065] A connecting frame 5031 is slidably connected to the inner side of the limiting groove B503, one end of the connecting frame 5031 is fixedly connected to the outer edge of the end of the mounting shell 602, and both ends of the connecting frame 5031 are provided with bevel blocks 5032, and the bevels of the two bevel blocks 5032 are respectively adapted to the bevels at both ends of the push frame 505;

[0066] Memory springs 5041 are disposed on the inner sides of the two slide seats 504 , and the ends of the two memory springs 5041 are fixedly connected to the outer sides of the push frame 505 .

[0067] In this embodiment, while the mounting shell 602 is reciprocating, it will also push the connecting frame 5031 to move synchronously along the inner side of the limiting groove B503. In the process of the connecting frame 5031 moving toward the push frame 505, the inclined surfaces of the two bevel blocks 5032 at both ends of the push frame 505 will collide with each other, so that the push frame 505 is subjected to force and then moves downward along the inner side of the two slide seats 504. While the push frame 505 is moving downward, the arc plate 506 will be driven to move downward synchronously through the fixing frame A502, so that the arc plate 506 impacts the inner side of the filter element 3, and the filter element 3 will be impacted when it is impacted. Vibration is generated to cause impurities attached to the surface of the filter element 3 to fall off, thereby avoiding excessive accumulation of impurities that may cause clogging of the filter element 3, and allowing the filter element 3 to maintain good filtering performance for a long time. When the push frame 505 moves downward, the memory spring 5041 is forced to expand, and then when the connecting frame 5031 drives the inclined block away from the push frame 505, the elastic force of the memory spring 5041 can make the connecting frame 5031 move away from the push frame 505. The push frame 505 will be driven by the memory spring 5041 to return to its original position through the fixed frame B9 by driving the arc plate 506.

[0070] In this embodiment, the air outlet end 401 is provided for connection with the air compressor, so that the air compressor can draw air through the air inlet end 101 of the shell A1 into the interior of the shell A1 and the shell B4 for filtering. In the process of engaging the barrel cover 2 with one end of the shell A1, the outer side of one end of the rotating seat 201 is aligned with the inner side of one end of the filter element 3 for engagement, so as to support the filter element 3. While the barrel cover 2 is engaged with the shell A1, the internal threaded sleeve 203 is pushed along the slide groove 202 so that the port on the inner edge of the internal threaded sleeve 203 contacts the port on the outer edge of the external threaded sleeve 102, and then the external threaded sleeve 102 is rotated to threadably match the external threaded sleeve 102, so that when the external threaded sleeve 102 completely covers the internal threaded sleeve 203, the fixed installation work between the barrel cover 2 and the shell A1 can be completed, and the sealing between the barrel cover 2 and the shell A1 can be ensured.

[0071] In summary, the working principle of the present invention is as follows:

When the barrel cover 2 is clamped with the shell A1, the inner threaded sleeve 203 is pushed along the slide groove 202, so that the port on the inner edge of the inner threaded sleeve 203 is in contact with the port on the outer edge of the outer threaded sleeve 102, and then the outer threaded sleeve 102 is rotated to threadably match the outer threaded sleeve 102. When the outer threaded sleeve 102 completely covers the inner threaded sleeve 203, the fixing between the barrel cover 2 and the shell A1 is completed. Then, by setting The air outlet end 401 is used to connect with the air compressor, so that the air compressor can draw air through the air inlet end 101 of the shell A1 into the inside of the shell A1 and the shell B4 for filtering and processing, thereby completing the installation work, and then by starting the drive motor 11, the drive motor 11 drives the drive gear 13 to rotate through the connecting column 12, and when the drive gear 13 rotates, it meshes with the outer edge of the gear ring 702, so that the gear ring 702 drives the connecting seat 701 to rotate synchronously, wherein the fixing frame B9 set between the outer sides of the shell A1 and the shell B4 is used to ensure that the shell A1 and the shell B4 can always remain fixed, and then when the connecting seat 701 rotates, it will synchronously drive the L-shaped clamping member 704 to fix it. The fixed filter element 3 rotates synchronously, so that the filter element 3 can be in contact with the air more comprehensively, and the dust and impurities in the air are more evenly distributed on the filter element 3, avoiding the situation that the filter element 3 is partially blocked and overloaded due to excessive accumulation of impurities in a certain area of ​​the filter element 3. When the connecting seat 701 rotates, the ends of the two clamping columns 7011 are driven to move along the inner side of the oblique groove 6023. When the clamping column 7011 moves to conflict with the inclined surface on the inner side of the oblique groove 6023, it drives the mounting shell 602 to move along the outer side of the connecting pipe 601 toward the fixed plate 603, so that the inner side of the mounting shell 602 can squeeze the folded airbag 606, so that the internal space of the folded airbag 606 is compressed.Then, the airflow inside the folded airbag 606 enters the air blowing pipe B607 from the air blowing pipe A605, and then blows air from the ports of multiple one-way air blowing ends 608 toward the inner side of the filter element 3 through the air blowing pipe B607 to clean it, so as to remove the tiny particles and impurities that clog and adhere to the filter element 3, thereby extending the service life of the filter element 3. When the air blowing pipe B607 blows air to clean the filter element 3 through the one-way air blowing end 608, the rotation of the filter element 3 makes the one-way air blowing end 608 clean the filter element 3 more evenly, and the housing is installed. When the mounting shell 602 moves, it will be limited by a plurality of limit rods 6021, which is used to ensure the stability of the mounting shell 602 when it moves, and the plurality of return springs 6022 will be pressed by the mounting shell 602 and then shrink. When the clamping column 7011 moves out of the inclined surface inside the oblique groove 6023 during the rotation, it will fall back into the inclined surface inside the oblique groove 6023. Through the elastic force of the return spring 6022, the mounting shell 602 can be pushed, so that the inclined surface inside the oblique groove 6023 can intermittently fit with the end of the clamping column 7011, and when the clamping column 7011 is in the process of rotation, the inclined surface inside the oblique groove 6023 can fit with the end of the clamping column 7011 intermittently. When the end of the column 7011 is aligned with the inclined surface of the oblique groove 6023 again, the mounting shell 602 will drive the folding airbag 606 to expand, so that the folding airbag 606 draws air through the one-way air inlet valve 604, thereby replenishing the internal gas of the folding airbag 606 for the next air blowing cleaning work, and while the mounting shell 602 is moving back and forth, it will also push the connecting frame 5031 to move synchronously along the inner side of the limit groove B503. In the process of the connecting frame 5031 moving toward the push frame 505, the inclined push frames of the two bevel blocks 5032 will be pushed The oblique cut surfaces at both ends of 505 collide with each other, so that the push frame 505 is subjected to force and then moves down along the inner side of the two slide seats 504. When the push frame 505 moves down, the arc plate 506 is driven to move down synchronously through the fixed frame A502, so that the arc plate 506 impacts the inner side of the filter element 3, and the filter element 3 vibrates when impacted, so that the impurities attached to the surface of the filter element 3 fall off, thereby avoiding excessive accumulation of impurities and clogging of the filter element 3, thereby further enhancing the service life of the filter element 3 and enabling the filter element 3 to maintain good filtering performance for a long time.
