The valve core is driven to move by an electromagnet, so as to open or close the exhaust passage. When powered, the magnetic field generated by the electromagnetic coil drives the valve core or diaphragm to move, so as to open or close the exhaust port, achieve rapid exhaust or maintain a vacuum / pressure state, and open and close the exhaust according to requirements, and stabilize the system pressure.
[0003] A Chinese patent with the publication number CN214743379U discloses an electromagnetic automatic exhaust valve, which comprises a valve body, a left connector, a right connector, a control valve, and a gas connection pipe. The valve body is provided with a left connector on one side, the valve body is provided with a right connector on the side away from the left connector, the top of the valve body is provided with a control valve, and the bottom of the valve body is provided with a gas connection pipe. The connecting port is provided to be screw-connected with an external connection system through a connecting thread, and is clamped and fixed through the action of a fixed clamping plate and a spring clamping column. The double connection of clamping and screwing ensures the stability of the connection, and facilitates the installation and use of the device. The internal structure of the device is simple, the production difficulty is low, the device is convenient for large-scale production, the production cost is effectively reduced, the investment is saved, the operation of the device is convenient, and the practicality of the device is improved.
[0004] The existing exhaust valve has the following problems in use: first, the filtration and buffering treatment of the delivered gas pressure is inconvenient, which causes impurities to be easily mixed in the gas pressure, which may pollute and damage the pneumatic equipment; and second, there is a lack of effective buffering measures, which easily causes the gas pressure delivery process to be unstable, thereby affecting the performance and reliability of the entire pneumatic system.
[0005] Therefore, the present application provides a composite exhaust valve with an integrated buffering and filtering assembly. SUMMARY
[0006] In order to make up for the deficiencies of the prior art and solve the problem of inconvenience in filtering and buffering the gas pressure, the present application provides a composite exhaust valve with an integrated buffering and filtering assembly.
[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a composite exhaust valve with integrated buffer and filter components, including a housing, a support block fixedly disposed at one end of the housing, an air inlet fixedly disposed on the support block, an exhaust head fixedly connected to one side of the support block, an exhaust head No. 1 connected to the other end of the housing, an adjustment mechanism disposed inside the housing, and a sealing component disposed inside the support block. The support block has a cavity inside, which is connected to the end of the air inlet head. The cavity has a concave groove inside, which is located below the air inlet head. A sealing strip is provided at the top of the concave groove. A cylinder is connected to the bottom of the concave groove in an array, and the top of the cylinder is connected to the inside of the concave groove. A connecting rod is fixedly provided at the bottom of the concave groove. A base plate is fixedly connected to the bottom end of the connecting rod. A buffer mechanism is provided inside the cavity, which is located below the base plate. A filter cartridge is embedded in the cylinder. The cylinder is equipped with a cleaning mechanism for cleaning the inside of the filter cartridge, and the bottom plate is equipped with a storage mechanism. The bottom end of the cylinder is connected to the inside of the bottom plate.
[0008] By adopting the above scheme, when pneumatic instruments use a composite exhaust valve with integrated buffer and filter components for exhaust, the housing is installed on one side of the air-using equipment. The air inlet head is connected to the pneumatic system through a pipe, the first exhaust head is connected to the air-using equipment, and the second exhaust head is connected to a silencer through a pipe. The movement of the adjusting mechanism can drive the movement of the sealing component, controlling the connection status between the air inlet head and the first and second exhaust heads, thereby controlling the exhaust flow of the air-using equipment and improving its working efficiency. When using the composite exhaust valve with integrated buffer and filter components, the concave groove is connected to the bottom of the air inlet head. The driving air pressure flows through the air inlet head into the concave groove, and then the air pressure flows into the cylinder. Next, the flowing air pressure flows into the cavity after being filtered by the filter cartridge, effectively intercepting particles and other impurities in the air source, preventing blockage of the solenoid valve core and cylinder inlet, preventing valve jamming or cylinder inner wall wear, reducing damage to seals by impurities, lowering the risk of leakage of pneumatic components, extending the service life of the entire pneumatic system, and outputting clean compressed air, preventing impurities from contaminating terminal equipment or workpieces. Through the cooperation of the adjustment mechanism and sealing components, the filtered air pressure will flow into the first exhaust head and the second exhaust head respectively to control the operation of the air-using equipment. When delivering clean compressed air, the buffer mechanism can effectively slow down the flow rate and pressure fluctuations of the airflow, preventing high-speed airflow from impacting components such as the valve core, and effectively improving operational stability.
[0009] Preferably, the air intake head is provided with a sealing ring, the housing is fixedly provided with a mounting bracket, the mounting bracket is fixedly provided with a control module, and the control module is externally powered. The concave groove is symmetrically provided with positioning plates, and the positioning plates are fixedly connected to the inner wall of the cavity. The support block is provided with a maintenance groove, and the maintenance groove is connected to the cavity. The maintenance groove is fixedly provided with a sealing plate for sealing the maintenance groove by bolts.
[0010] By adopting the above solution, the sealing performance at the connection between the air inlet head and the pneumatic system can be effectively improved by the sealing ring. The housing provides installation space for the control module through the mounting bracket. The control module can control the operation of the composite exhaust valve with integrated buffer and filter components. The concave groove can be fixedly installed by the positioning plate and bolts. The sealing strip is used to seal the gaps in the concave groove and the top wall of the cavity to prevent air pressure leakage.
[0011] Preferably, the adjustment mechanism includes a slide groove, a first electromagnet, and a magnetic block. The slide groove is disposed inside the mounting frame, the first electromagnet is fixedly disposed inside the slide groove, and the magnetic block is disposed inside the slide groove, with the magnetic block located on one side of the first electromagnet. A pull rod is fixedly installed on the magnetic block, and a limiting ring corresponding to the pull rod is fixedly installed on the mounting bracket. The pull rod passes through the limiting ring. A return spring is arranged around the pull rod, and one end of the return spring is fixedly connected to the limiting ring. A stop block is fixedly installed on the pull rod, and the other end of the return spring is fixedly connected to the stop block.
[0012] By adopting the above scheme, the control module controls the first electromagnet to work and generate magnetic force, which in turn causes the magnetic block to move toward the first electromagnet. When the magnetic block moves, it will drive the pull rod to move. The limit ring will guide the pull rod to move smoothly. When the first electromagnet is adjusted and working, the reset spring will reset. With the cooperation of the stop block, the pull rod will be driven to reset, which will in turn drive the magnetic block to reset. When the pull rod moves, it will drive the sealing component to move.
[0013] Preferably, the sealing component includes a diversion groove and a sealing block. The diversion groove is disposed inside the support block and has a connecting hole that communicates with the interior of the cavity. The sealing block is disposed inside the diversion groove. One end of the diversion groove is connected to the first exhaust head, and the other end of the diversion groove is connected to the interior of the housing.
[0014] By adopting the above scheme, when the No. 1 electromagnet is energized, the sealing block will be located on the left side of the connecting hole. Then, when the filtered air pressure inside the cavity enters the diversion groove through the connecting hole, the air pressure will flow to the air-using equipment (i.e., the air inlet head and the No. 1 exhaust head are connected). Conversely, when the No. 1 electromagnet is de-energized, the reset spring will reset and push the sealing block to the right side of the connecting hole (the air inlet head and the No. 2 exhaust head are connected). After the air pressure enters the diversion groove, it will flow into the housing and then into the No. 2 exhaust head for exhaust treatment.
[0015] Preferably, the cleaning mechanism includes a bracket, a bearing, a rotating shaft, a connecting plate, and a cleaning plate. The bracket, corresponding to the cylinder, is fixedly mounted on the concave groove. The bearing is fixedly embedded inside the bracket. The rotating shaft is located inside the cylinder, and its end is fixedly connected to the inner ring of the bearing. The connecting plate is symmetrically mounted on the rotating shaft. The cleaning plate is fixedly mounted on the connecting plate, and its side is in contact with the inner ring of the filter cartridge. A turbine is provided inside the cylinder, and its inner ring is fixedly connected to the rotating shaft. The turbine is located above the connecting plate.
[0016] By adopting the above solution, the concave groove is supported by a bracket and bearings to form a rotating shaft. When the air pressure flows into contact with the turbine, the turbine rotates. The rotation of the turbine drives the rotating shaft to rotate, and the rotating shaft, through the connecting plate, drives the cleaning plate to move. As the cleaning plate moves, it adheres to the inner wall of the filter cartridge, removing the particles filtered and intercepted by the filter cartridge. This effectively prevents particles from accumulating and clogging the filter holes, ensuring smooth airflow, maintaining the filtration effect, reducing filter cartridge resistance, and preventing the filter media from prematurely failing due to excessive clogging. This ensures the efficiency of air pressure filtration and cleaning. The cleaning plate is removable for maintenance, and can be processed during regular maintenance.
[0017] Preferably, a frame is fixedly installed on the top of the support, and a second electromagnet corresponding to the rotating shaft is fixedly installed on the top of the frame. The rotating shaft is made of magnetic material, and drive plates are symmetrically arranged on the rotating shaft. The ends of the drive plates are arc-shaped, and a vibration component is installed on the cylinder.
[0018] By adopting the above solution, the bracket provides installation space for the No. 2 electromagnet through the frame. When it is not necessary to clean the inner wall of the filter cartridge, the No. 2 electromagnet is controlled to generate a strong magnet, which will position the rotating shaft and prevent the cleaning plate from moving to clean the inner wall of the filter cartridge. The working state of the No. 2 electromagnet can be controlled according to the needs. When the rotating shaft rotates, it will drive the drive plate to move.
[0019] Preferably, the vibration assembly includes a movable groove, a sliding block, a driven shaft, a limiting plate, a striking block, and a driving spring. The movable groove array is arranged on the cylinder, and one end of the movable groove is connected to the inner ring of the cylinder. The sliding block passes through the movable groove, and the end of the sliding block is arc-shaped. The driven shaft is arranged inside the movable groove, and one end of the driven shaft is fixedly connected to the sliding block. The limiting plate is fixedly arranged inside the movable groove, and the driven shaft passes through the limiting plate. The striking block is arranged inside the movable groove, and the striking block is located on one side of the limiting plate. One end of the driven shaft is fixedly connected to the striking block. The driving spring is fixedly arranged inside the movable groove, and the other end of the driving spring is fixedly connected to the striking block.
[0020] By adopting the above scheme, when the rotating shaft rotates and drives the drive plate to move, the drive plate will contact one end of the sliding block, thereby driving the sliding block to move. The movement of the sliding block will compress the drive spring through the cooperation of the driven shaft and the striking block. When the drive plate is no longer in contact with the sliding block, the drive spring will reset and drive the striking block, the driven shaft and the sliding block to reset. At the same time, the striking block will contact and collide with the limit plate, which will cause the movable groove to vibrate, and then cause the cylinder and filter cartridge to vibrate slightly. After the vibration, it will assist in the cleaning treatment of the filter cartridge.
[0021] Preferably, the edge of the base plate is fitted to the inner wall of the cavity, and the base plate is symmetrically provided with through grooves, and a filter plate is fixedly installed inside the through grooves.
[0022] By adopting the above scheme, the compressed air entering the cavity will flow into the through groove, and the air can be further filtered by the filter plate.
[0023] Preferably, the buffer mechanism includes a support rod, a baffle, a reducer, and a drive motor. The support rod is symmetrically rotated inside the cavity, the baffle is symmetrically arranged on the support rod, the reducer corresponding to the support rod is arranged inside the support block, and the end of the support rod is fixedly connected to the output end of the reducer. The drive motor is fixedly arranged inside the support block, and the output end of the drive motor is fixedly connected to the input end of the reducer. The baffle is located on one side of the connecting hole.
[0024] By adopting the above scheme, the compressed air filtered by the through groove and filter plate will flow to the space between the bottom plate and the cavity. The control drive motor will drive the support rod to move, and the movement of the support rod will drive the baffle to move. The movement of the baffle will adjust the lateral cross section between the bottom plate and the cavity, which can control the flow direction of the compressed air. The change of the baffle angle will adjust the effective cross section of the compressed air flow. The narrower the space through which the airflow passes, the lower the flow velocity will be, thus achieving the purpose of throttling and buffering.
[0025] Preferably, the storage mechanism includes a side plate, a mounting groove, a storage groove, and a magnetic plate. The side plates are symmetrically arranged inside the base plate, the mounting groove is arranged inside the base plate and the side plates are located above the mounting groove, the storage groove is arranged inside the mounting groove, the magnetic plate is arranged on the storage groove, and the base plate is made of magnetic material. The storage slot is provided with a threaded hole, and the bottom plate is provided with a hole corresponding to the threaded hole. A positioning bolt is inserted into the hole, and the outer surface of the positioning bolt is threadedly connected to the inside of the threaded hole.
[0026] By adopting the above solution, the impurities removed from the inner wall of the filter cartridge will fall into the bottom plate. With the cooperation of the side plate, the fallen particles will slide into the collection tank for storage. During later maintenance, the positioning bolt can be rotated to separate the positioning bolt from the threaded hole, so that the collection tank is no longer positioned. The collection tank is detachable. After the collection tank is detached, the collected impurities can be cleaned.
[0027] The beneficial effects of this invention are as follows: 1. The present invention discloses a composite exhaust valve with integrated buffering and filtering components. By setting a filter cartridge and a baffle, it can efficiently buffer and filter the delivered air pressure, ensuring the stable operation of pneumatic equipment. The air pressure first flows into the inside of the cylinder, and after being filtered by the filter cartridge, it enters the cavity. This effectively intercepts impurities such as particles in the air source, preventing blockage of the solenoid valve core and the cylinder inlet, preventing valve jamming and cylinder inner wall wear, reducing damage to the seals by impurities, lowering the risk of leakage of pneumatic components, and extending the service life of the entire pneumatic system. In addition, adjusting the baffle angle can change the effective flow cross section of the compressed air. The narrower the flow space, the slower the airflow velocity, achieving throttling and buffering. After the airflow hits the baffle, it is forced to flow around and split, and the impact energy is dispersed, avoiding concentrated impact on subsequent components, reducing pressure fluctuations, ensuring stable air pressure, and guaranteeing the stability of the composite exhaust valve with integrated buffering and filtering components.
[0028] 2. The composite exhaust valve with integrated buffer and filtration components described in this invention facilitates the removal of filtered particulate matter through the cleaning plate and turbine, ensuring the filtration effect of the filter cartridge. When air pressure flows into the cylinder, it first contacts the turbine, which has an array of inclined blades that cause it to rotate. The rotation of the turbine drives the rotating shaft to rotate synchronously inside the bearing. The rotation of the rotating shaft drives the cleaning plate to move through the connecting plate. The cleaning plate, due to its contact with the inner wall of the filter cartridge, removes the particulate matter filtered and intercepted by the filter cartridge, effectively preventing the accumulation of particulate matter from clogging the filter holes, ensuring smooth airflow, maintaining the filtration effect, reducing filter cartridge resistance, and ensuring the normal operation of the composite exhaust valve with integrated buffer and filtration components.
[0029] 3. The composite exhaust valve with integrated buffer and filtration components described in this invention can further clean the filter cartridge through the setting of the knocking block and the movable groove, ensuring the filtration effect of air pressure transmission. When the rotating shaft rotates and drives the drive plate to move, the drive plate will contact one end of the sliding block, thereby driving the sliding block to move. The movement of the sliding block will compress the drive spring through the cooperation of the driven shaft and the knocking block. When the drive plate is no longer in contact with the sliding block, the drive spring will reset and drive the knocking block, the driven shaft and the sliding block to reset. At the same time, the knocking block will contact and collide with the limit plate, which will cause the movable groove to vibrate, and then cause the cylinder and the filter cartridge to vibrate slightly. After vibration, it will assist in cleaning the filter cartridge, ensuring the operation of the composite exhaust valve with integrated buffer and filtration components.
[0030] 4. The composite exhaust valve with integrated buffer and filtration components described in this invention facilitates the collection and processing of cleaned particulate matter through a set collection slot. The bottom plate is hollow, and impurities cleaned from the inner wall of the filter cartridge will fall into the bottom plate. With the cooperation of the side plates, the fallen particulate matter will slide into the collection slot for storage. During later maintenance, the positioning bolt can be rotated to separate the positioning bolt from the threaded hole, thereby eliminating the need to position the collection slot. The collection slot is detachable, and after disassembly, the collected impurities can be cleaned, thus achieving the purpose of facilitating the collection and processing of cleaned particles.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0035] like Figures 1 to 10 As shown in the embodiment of the present invention, a composite exhaust valve with integrated buffer and filter components includes a housing 1. A support block 2 is fixedly mounted on one end of the housing 1, and an air inlet head 3 is fixedly mounted on the support block 2. A first exhaust head 5 is fixedly connected to one side of the support block 2, and a second exhaust head 6 is connected to the other end of the housing 1. An adjustment mechanism is provided inside the housing 1, and a sealing component is provided inside the support block 2. A cavity 17 is provided inside the support block 2, and the cavity 17 is connected to the end of the air inlet head 3. A concave groove 19 is provided inside the cavity 17, and the concave groove 19 is located below the air inlet head 3. A sealing strip 21 is provided at the top of the concave groove 19. A cylinder 24 is arrayed and connected to the bottom of the concave groove 19, and the top of the cylinder 24 is connected to the inside of the concave groove 19. A connecting rod 22 is fixedly provided at the bottom of the concave groove 19, and a base plate 23 is fixedly connected to the bottom end of the connecting rod 22. A buffer mechanism is provided inside the cavity 17, and the buffer mechanism is located below the base plate 23. A filter cartridge 35 is embedded on the cylinder 24. A cleaning mechanism for cleaning the inside of the filter cartridge 35 is provided inside the cylinder 24. A storage mechanism is provided inside the base plate 23, and the bottom end of the cylinder 24 is connected to the inside of the base plate 23. The control module 8 is electrically connected to the internal electronic equipment of the composite exhaust valve with integrated buffer and filter components, and can remotely control the operation of the composite exhaust valve with integrated buffer and filter components (prior art). When pneumatic equipment uses a composite exhaust valve with integrated buffer and filter components for exhaust, the housing 1 is installed on one side of the air-using equipment. The air inlet 3 is connected to the pneumatic system through a pipe, the first exhaust head 5 is connected to the air-using equipment, and the second exhaust head 6 is connected to a silencer through a pipe. The movement of the adjusting mechanism can drive the movement of the sealing component, control the connection status of the air inlet 3 with the first exhaust head 5 and the second exhaust head 6, and thus control the exhaust on and off of the air-using equipment, thereby improving the working efficiency of the air-using equipment. When using a composite exhaust valve with integrated buffer and filter components, the concave groove 19 is connected to the bottom of the air inlet head 3. The driving air pressure flows into the concave groove 19 through the air inlet head 3, and then flows into the cylinder 24. After being filtered by the filter cartridge 35, the flowing air pressure flows into the cavity 17, effectively intercepting particles and other impurities in the air source, avoiding clogging of the solenoid valve core and cylinder inlet, preventing valve jamming or cylinder inner wall wear, reducing the damage of impurities to the seals, reducing the risk of leakage of pneumatic components, extending the service life of the entire pneumatic system, and outputting clean compressed air, avoiding impurities from contaminating terminal equipment or workpieces. Through the cooperation of the adjustment mechanism and sealing components, the filtered air pressure will flow into the first exhaust head 5 and the second exhaust head 6 respectively, controlling the operation of the air-using equipment. When delivering clean compressed air, the buffer mechanism can effectively slow down the flow rate and pressure fluctuations of the airflow, avoid high-speed airflow impacting the valve core and other components, and effectively improve the operational stability. When the air pressure flows into the cylinder 24, it first comes into contact with the turbine 30. The turbine 30 has an array of inclined blades, which causes the turbine 30 to rotate. When the turbine 30 rotates, it drives the rotating shaft 29 to rotate synchronously inside the bearing 26. When the rotating shaft 29 rotates, it drives the cleaning mechanism to move. The movement of the cleaning mechanism removes the particles filtered and intercepted by the inner ring of the filter cartridge 35. The removed particles fall into the collection mechanism for collection, so that the collected dirt can be removed during later maintenance and repair.
[0036] Furthermore, a sealing ring 4 is provided on the air intake head 3, a mounting bracket 7 is fixedly provided inside the housing 1, a control module 8 is fixedly provided inside the mounting bracket 7, and the control module 8 is connected to an external power supply, a positioning plate 20 is symmetrically provided on the concave groove 19, and the positioning plate 20 is fixedly connected to the inner wall of the cavity 17, a maintenance groove 47 is provided inside the support block 2, and the maintenance groove 47 is connected to the cavity 17, and a sealing plate 48 for sealing the maintenance groove 47 is fixedly provided inside the maintenance groove 47 by bolts; The sealing ring 4 can effectively improve the sealing performance at the connection between the air inlet head 3 and the pneumatic system. The housing 1 provides installation space for the control module 8 through the mounting bracket 7. The control module 8 can control the operation of the composite exhaust valve with integrated buffer and filter components. The concave groove 19 can be fixedly installed by the positioning plate 20 and bolts. The sealing strip 21 is used to seal the gap between the concave groove 19 and the top wall of the cavity 17 to prevent air pressure leakage. The sealing plate 48 is removable and no longer seals the inspection groove 47, so that personnel can easily inspect the inside of the cavity 17 through the inspection groove 47.
[0037] Furthermore, the adjustment mechanism includes a slide 9, a first electromagnet 10, and a magnetic block 11. The slide 9 is located inside the mounting frame 7. The first electromagnet 10 is fixedly located inside the slide 9. The magnetic block 11 is located inside the slide 9 and is located on one side of the first electromagnet 10. A pull rod 13 is fixedly installed on the magnetic block 11. A limiting ring 12 corresponding to the pull rod 13 is fixedly installed on the mounting frame 7, and the pull rod 13 passes through the limiting ring 12. A return spring 14 is arranged around the pull rod 13, and one end of the return spring 14 is fixedly connected to the limiting ring 12. A stop block 56 is fixedly installed on the pull rod 13, and the other end of the return spring 14 is fixedly connected to the stop block 56. When the control adjustment mechanism moves, the control module 8 controls the first electromagnet 10 to work and generate magnetic force, which in turn causes the magnetic block 11 to move toward the first electromagnet 10. When the magnetic block 11 moves, it will drive the pull rod 13 to move. The limit ring 12 will guide the pull rod 13 to move smoothly. When the first electromagnet 10 is adjusted and working, the reset spring 14 will reset. With the cooperation of the stop block 56, the pull rod 13 will be driven to reset, which will in turn drive the magnetic block 11 to reset. When the pull rod 13 moves, it will drive the sealing component to move.
[0038] Furthermore, the sealing assembly includes a diversion groove 15 and a sealing block 16. The diversion groove 15 is disposed inside the support block 2. A connecting hole 18 is provided on the diversion groove 15 and the connecting hole 18 is connected to the inside of the cavity 17. The sealing block 16 is disposed inside the diversion groove 15. One end of the diversion groove 15 is connected to the first exhaust head 5, and the other end of the diversion groove 15 is connected to the inside of the housing 1. When the first electromagnet 10 is energized or de-energized, the pull rod 13 will drive the sealing block 16 to move. When the first electromagnet 10 is energized, the sealing block 16 will be located to the left of the connecting hole 18. Then, when the filtered air pressure inside the cavity 17 enters the diversion groove 15 through the connecting hole 18, the air pressure will flow to the air-using equipment (i.e., the air inlet 3 and the first exhaust head 5 are connected). Conversely, when the first electromagnet 10 is de-energized, the reset spring 14 will reset and push the sealing block 16 to the right of the connecting hole 18 (the air inlet 3 and the second exhaust head 6 are connected). After the air pressure enters the diversion groove 15, it will flow into the housing 1 and then flow into the second exhaust head 6 for exhaust treatment.
[0039] Furthermore, the cleaning mechanism includes a bracket 25, a bearing 26, a rotating shaft 29, a connecting plate 31, and a cleaning plate 32. The bracket 25, corresponding to the cylinder 24, is fixedly mounted on the concave groove 19. The bearing 26 is fixedly embedded inside the bracket 25. The rotating shaft 29 is located inside the cylinder 24, and the end of the rotating shaft 29 is fixedly connected to the inner ring of the bearing 26. The connecting plate 31 is symmetrically arranged on the rotating shaft 29. The cleaning plate 32 is fixedly mounted on the connecting plate 31, and the side of the cleaning plate 32 is in contact with the inner ring of the filter cartridge 35. A turbine 30 is provided inside the cylinder 24, and the inner ring of the turbine 30 is fixedly connected to the rotating shaft 29. The turbine 30 is located above the connecting plate 31. The concave groove 19 supports the rotating shaft 29 through the cooperation of the bracket 25 and the bearing 26. When the air pressure flow comes into contact with the turbine 30, the turbine 30 will rotate. When the turbine 30 rotates, it will drive the rotating shaft 29 to rotate. When the rotating shaft 29 rotates, it will drive the cleaning plate 32 to move through the connecting plate 31. As the cleaning plate 32 moves and fits against the inner wall of the filter cartridge 35, it will remove the particles filtered and intercepted by the inner wall of the filter cartridge 35, effectively preventing the accumulation of particles and clogging the filter holes, ensuring smooth airflow, maintaining the filtration effect, reducing the resistance of the filter cartridge 35, and preventing the filter material from being prematurely scrapped due to excessive clogging. This ensures the efficiency of air pressure filtration and cleaning. The cleaning plate 32 is detachable for maintenance and can be processed during regular maintenance.
[0040] Furthermore, a frame 27 is fixedly installed on the top of the bracket 25, and a second electromagnet 28 corresponding to the rotating shaft 29 is fixedly installed on the top of the frame 27. The rotating shaft 29 is made of magnetic material, and a drive plate 33 is symmetrically arranged on the rotating shaft 29. The end of the drive plate 33 is arc-shaped, and a vibration component is installed on the cylinder 24. The bracket 25 provides installation space for the second electromagnet 28 through the frame 27. When it is not necessary to clean the inner wall of the filter cartridge 35, the second electromagnet 28 is controlled to generate a strong magnet, which will position the rotating shaft 29, thus preventing the cleaning plate 32 from moving to clean the inner wall of the filter cartridge 35. The working state of the second electromagnet 28 can be controlled according to the needs. When the rotating shaft 29 rotates, it will drive the drive plate 33 to move.
[0041] Furthermore, the vibration assembly includes a movable groove 34, a sliding block 36, a driven shaft 37, a limiting plate 38, a striking block 39, and a drive spring 40. The movable groove 34 is arrayed on the cylinder 24, and one end of the movable groove 34 is connected to the inner ring of the cylinder 24. The sliding block 36 passes through the inside of the movable groove 34, and the end of the sliding block 36 is arc-shaped. The driven shaft 37 is located inside the movable groove 34, and one end of the driven shaft 37 is fixedly connected to the sliding block 36. The limiting plate 38 is fixedly located inside the movable groove 34, and the driven shaft 37 passes through the limiting plate 38. The striking block 39 is located inside the movable groove 34, and the striking block 39 is located on one side of the limiting plate 38. One end of the driven shaft 37 is fixedly connected to the striking block 39. The drive spring 40 is fixedly located inside the movable groove 34, and the other end of the drive spring 40 is fixedly connected to the striking block 39. When the rotating shaft 29 rotates and drives the drive plate 33 to move, the drive plate 33 will contact one end of the sliding block 36, thereby driving the sliding block 36 to move. The movement of the sliding block 36 will compress the drive spring 40 through the cooperation of the driven shaft 37 and the striking block 39. When the drive plate 33 is no longer in contact with the sliding block 36, the drive spring 40 will reset and drive the striking block 39, the driven shaft 37 and the sliding block 36 to reset. At the same time, the striking block 39 will contact and collide with the limiting plate 38, which will cause the movable groove 34 to vibrate, which will cause the cylinder 24 and the filter cartridge 35 to vibrate slightly. After the vibration, it will assist in cleaning the filter cartridge 35.
[0042] Furthermore, the edge of the bottom plate 23 is fitted to the inner wall of the cavity 17, and the bottom plate 23 is symmetrically provided with through grooves 41, and a filter plate 42 is fixedly installed inside the through grooves 41. The compressed air that enters the cavity 17 will flow into the through groove 41, and the air can be further filtered by the filter plate 42. The filter plate 42 can be maintained regularly and can be disassembled and replaced.
[0043] Furthermore, the buffer mechanism includes a support rod 43, a baffle 44, a reducer 45, and a drive motor 46. The support rod 43 is symmetrically rotated inside the cavity 17, the baffle 44 is symmetrically arranged on the support rod 43, the reducer 45 corresponding to the support rod 43 is arranged inside the support block 2, and the end of the support rod 43 is fixedly connected to the output end of the reducer 45. The drive motor 46 is fixedly arranged inside the support block 2, and the output end of the drive motor 46 is fixedly connected to the input end of the reducer 45. The baffle 44 is located on one side of the connecting hole 18. Compressed air filtered through the through slot 41 and filter plate 42 flows into the space between the bottom plate 23 and the cavity 17. The control drive motor 46 drives the support rod 43 to move, and the movement of the support rod 43 drives the baffle 44 to move. The movement of the baffle 44 adjusts the lateral cross section between the bottom plate 23 and the cavity 17, which controls the flow direction of the compressed air. The change of the angle of the baffle 44 adjusts the effective cross section of the compressed air flow. The narrower the space through which the airflow passes, the lower the flow velocity, thus achieving the purpose of throttling and buffering. After the airflow hits the baffle 44, it is forced to flow around and split, and the impact energy is dispersed, avoiding concentrated impact on subsequent components, reducing pressure fluctuations, and ensuring the stability of air pressure.
[0044] Furthermore, the storage mechanism includes a side plate 49, a mounting groove 50, a storage groove 51, and a magnetic plate 52. The side plate 49 is symmetrically arranged inside the base plate 23. The mounting groove 50 is arranged inside the base plate 23, and the side plate 49 is located above the mounting groove 50. The storage groove 51 is arranged inside the mounting groove 50. The magnetic plate 52 is arranged on the storage groove 51. The base plate 23 is made of magnetic material. The storage groove 51 is provided with a threaded hole 55. The base plate 23 is provided with a hole 53 corresponding to the threaded hole 55. A positioning bolt 54 passes through the hole 53, and the outer surface of the positioning bolt 54 is threadedly connected to the inside of the threaded hole 55. The base plate 23 is hollow, and the impurities removed from the inner wall of the filter cartridge 35 will fall into the base plate 23. With the cooperation of the side plate 49, the fallen particles will slide into the collection tank 51 for storage. During later maintenance, the positioning bolt 54 can be rotated to separate the positioning bolt 54 from the threaded hole 55, so that the collection tank 51 no longer needs to be positioned. The collection tank 51 is detachable. After the collection tank 51 is detached, the collected impurities can be cleaned. When installing the collection tank 51, after the collection tank 51 is placed inside the installation slot 50, the magnetic plate 52 will temporarily limit the position of the collection tank 51. When positioning and installing the collection tank 51, it is not necessary to hold the collection tank 51 for positioning.
[0045] Working principle: First, when using a composite exhaust valve with integrated buffer and filter components, the concave groove 19 is connected to the bottom of the air inlet head 3. The driving air pressure flows into the concave groove 19 through the air inlet head 3, and then flows into the cylinder 24. The flowing air pressure is then filtered by the filter cartridge 35 and flows into the cavity 17, effectively intercepting particles and other impurities in the air source. This prevents blockage of the solenoid valve core and cylinder inlet, prevents valve jamming or cylinder wall wear, reduces damage to seals from impurities, lowers the risk of leakage in pneumatic components, extends the service life of the entire pneumatic system, and outputs clean compressed air, preventing impurities from contaminating terminal equipment or workpieces. The operation of the first electromagnet 10 generates magnetic force, which causes the magnetic block 11 to move towards the first electromagnet 10. When the magnetic block 11 moves, it drives the pull rod 13 to move. The limit ring 12 guides the pull rod 13 to move smoothly. When the first electromagnet 10 is adjusted, the return spring 14 resets. With the cooperation of the stop block 56, it drives the pull rod 13 to reset, which in turn drives the magnetic block 11 to reset. When the first electromagnet 10 is energized, the sealing block 16 will be located to the left of the connecting hole 18. Then, when the filtered air pressure inside the cavity 17 enters the diversion groove 15 through the connecting hole 18, the air pressure will flow to the air-using equipment. Conversely, when the first electromagnet 10 is de-energized, the return spring 14 resets, which will push the sealing block 16 to the right of the connecting hole 18. After the air pressure enters the diversion groove 15, it will flow into the housing 1, and then into the second exhaust head 6 for further processing. In the exhaust treatment process, when delivering clean compressed air, the buffer mechanism effectively reduces airflow velocity and pressure fluctuations, preventing high-speed airflow from impacting components such as the valve core, thus improving operational stability. Compressed air filtered through the through-slot 41 and filter plate 42 flows into the space between the base plate 23 and the cavity 17. The drive motor 46 controls the movement of the support rod 43, which in turn moves the baffle 44. The movement of the baffle 44 adjusts the lateral cross-section between the base plate 23 and the cavity 17, controlling the direction of compressed air flow. Changing the angle of the baffle 44 adjusts the effective cross-section of the compressed air flow. The narrower the space through which the airflow passes, the lower the flow velocity, achieving the purpose of throttling and buffering. Furthermore, after impacting the baffle 44, the airflow is forced to bypass and split, reducing the impact energy. The airflow is dispersed to avoid concentrated impact on subsequent components, reducing pressure fluctuations and ensuring air pressure stability. When the airflow enters the cylinder 24, it first contacts the turbine 30. The turbine 30 has an array of inclined blades, which causes the turbine 30 to rotate. When the turbine 30 rotates, it drives the rotating shaft 29 to rotate synchronously inside the bearing 26. When the rotating shaft 29 rotates, it drives the cleaning plate 32 to move through the connecting plate 31. Because the cleaning plate 32 is in contact with the inner wall of the filter cartridge 35, it removes the particles filtered and intercepted by the inner wall of the filter cartridge 35, effectively preventing the accumulation of particles and clogging the filter holes, ensuring smooth airflow, maintaining the filtration effect, and reducing the resistance of the filter cartridge 35. When the rotating shaft 29 rotates and drives the drive plate 33 to move, the drive plate 33 will contact one end of the sliding block 36.This movement drives the sliding block 36 to move. The movement of the sliding block 36, through the cooperation of the driven shaft 37 and the striking block 39, compresses the drive spring 40. When the drive plate 33 is no longer in contact with the sliding block 36, the drive spring 40 resets, driving the striking block 39, the driven shaft 37, and the sliding block 36 to reset. Simultaneously, the striking block 39 contacts and collides with the limiting plate 38, causing the movable groove 34 to vibrate. This, in turn, causes the cylinder 24 and filter cartridge 35 to vibrate slightly. This vibration assists in cleaning the filter cartridge 35. The bottom plate 23 is hollow, allowing impurities removed from the inner wall of the filter cartridge 35 to fall into its interior. Through the cooperation of the side plate 49, the fallen particles slide into the collection groove 51 for storage. For later maintenance, the positioning bolt 54 can be rotated to separate it from the threaded hole 55, thus ceasing to position the collection groove 51. The collection groove 51 is removable, allowing for the removal of collected impurities.
