Abstract
Description
Technical Field
[0001] This invention relates to the field of air filter technology, specifically to an ultra-high pressure miniature air filter. Background Technology
[0002] Air filters are devices used to remove pollutants such as particulate matter, dust, pollen, and smoke from the air. They are widely used in industry, homes, and automobiles. Their working principle is to capture or degrade harmful substances in the air through physical or chemical means. Air filters typically consist of filter screens, filter elements, or filter bags made of different materials, and can be classified as pre-filters, medium-efficiency filters, and high-efficiency filters based on their filtration effectiveness. Regularly replacing filters can maintain good air quality, ensuring the proper functioning of equipment and protecting people's health.
[0003] Chinese patent CN217068155U discloses a low-resistance, high-efficiency air filter, including a housing and a sliding box disposed within the housing. The housing's air inlet is equipped with a dust-blocking mechanism, which includes a dust-blocking plate movably connected to the housing via a connecting assembly. The housing's air outlet is equipped with the sliding box, which is slidably connected to the housing, with the sliding direction parallel to the gas delivery direction. A filter assembly, a fan, and an air outlet plate are sequentially arranged within the sliding box along the gas flow direction. The fan is mounted on a fan support frame, and its air outlet is connected to an air outlet on the air outlet plate. The fan support frame is mounted on the sliding box. The filter assembly includes a support frame and filter plates, with multiple support frames spaced apart. When filter plates need to be replaced, the sliding box can be pulled out first, and then the support frames can be swung away from the housing, facilitating filter plate removal and installation.
[0004] However, current air filters have the following problems: when a current air filter becomes clogged during use, it needs to be stopped to replace the filter element. Therefore, the replacement process will cause the equipment connected to the air filter to stop working, resulting in a decrease in the working efficiency of the connected equipment. Therefore, we propose an ultra-high pressure miniature air filter. Summary of the Invention

A hydraulic rod is fixed to the top of the inner wall of the control box body, and a pressing plate is fixed to the bottom of the telescopic end of the hydraulic rod.
[0007] According to the above technical solution, the top two sides of the support frame are provided with circular grooves for inserting the bottom pipe of the air filter body, and the bottom of the support frame is in contact with the inner wall of the U-shaped track plate.
[0008] According to the above technical solution, the support component includes a support block fixed to the bottom of the inner wall of the control box body, a long rod fixed to the side of the support block, and a slider slidably installed on the outer wall of the long rod, the slider being the moving end of the support component.
[0009] According to the above technical solution, positioning blocks are provided on both sides of the threaded sleeve and the slider, and four L-shaped blocks are provided on the side of the hollow support platform. The four L-shaped blocks are respectively located on the displacement trajectory of each positioning block.
[0010] According to the above technical solution, an electric push rod is fixed to the inner wall of the hollow support platform, a push frame is fixed to the telescopic end of the electric push rod, a rubber ring is fixed to the top of the push frame, a retaining ring is fixed to the top of the rubber ring, an L-shaped stop block is fixed to the top of the hollow support platform, the L-shaped stop block is located on the displacement trajectory of the retaining ring, and a placement groove for placing the push frame, rubber ring, and retaining ring is provided on the top of the hollow support platform.
[0011] According to the above technical solution, an auxiliary device is provided on the top of the push frame. The auxiliary device includes two irregularly shaped plates. The bottom of the two irregularly shaped plates is fixed to the top of the push frame. A vertical rod is fixed to the top of the two irregularly shaped plates. A support rod is hinged to the top of the vertical rod. An arc block is fixed to the top of the support rod. A spring is provided between the arc block and the irregularly shaped plate. A limit block is fixed to the side of the U-shaped track plate. A support arc plate for supporting the air filter body is fixed to the side of the limit block.
[0012] According to the above technical solution, a fixing plate is fixed to the top of the support plate, and elastic telescopic rods are fixed to both sides of the fixing plate. Multiple thin rods are fixed to the telescopic ends of the elastic telescopic rods.
[0013] According to the above technical solution, a guide hollow disc is fixed at two circular grooves at the top of the support frame, and the central hollow ring of the guide hollow disc is equal to the radius of the circular groove of the support frame.
[0014] This invention provides an ultra-high pressure miniature air filter. It has the following beneficial effects: (1) The present invention, through the cooperation of hollow support platform, connecting port, hydraulic rod, pressing plate, L-shaped tube, air outlet block, fixing block, motor, threaded rod, threaded sleeve, support plate, placement rack, air filter body, long block, support frame, and U-shaped track plate, enables the extension and retraction end of the hydraulic rod to drive the pressing plate to press the second set of air filter bodies, thereby realizing the switching of the two sets of air filter bodies. This avoids the problem that when it is necessary to stop using the air filter body and replace the filter element of the air filter body, the equipment connected to the air filter body will stop using during the replacement process, resulting in a decrease in the working efficiency of the connected equipment. At the same time, through the cooperation of positioning block, L-shaped block, fixing block, motor, threaded rod, threaded sleeve, support plate, placement rack, and air filter body, the second set of air filter bodies is located exactly at the connecting port of the hollow support platform, realizing the positioning of the second set of air filter bodies and the connecting port of the hollow support platform, avoiding the problem of deviation between the second set of air filter bodies and the connecting port.
[0015] (2) In this invention, through the cooperation of electric push rod, push frame, rubber ring, retaining ring, L-shaped block, placement groove, air filter body, hollow support platform and connection port, when the retaining ring moves to the L-shaped block, it will be blocked by the L-shaped block and cannot move. At this time, the push frame will continue to move and squeeze the rubber ring, thereby deforming the rubber ring. The deformation of the rubber ring will seal the connection port between the air filter body and the hollow support platform of the second group.
[0016] (3) The present invention uses the combination of irregular plate, vertical rod, support rod, arc block, spring, limit block, support arc plate, fixed plate, elastic telescopic rod and thin rod to make the air filter body rest against the inner wall of the support arc plate, so that the air filter body is in an inclined state. The inclined air filter body can be more convenient for the staff to take out the air filter body from the control box body. At the same time, the inclined state breaks the space limitation of vertical picking and placing. When putting it in, gravity can be used to push it in smoothly, reducing the action of repeatedly adjusting the position and greatly shortening the operation time of a single replacement. At the same time, through the cooperation of elastic telescopic rod and thin rod air filter body, the elastic telescopic rod can make the air filter body moving upward always tilted in the direction of support arc plate.
[0017] (4) In this invention, through the cooperation of arc block, spring, limiting block, supporting arc plate, fixing plate, elastic telescopic rod, thin rod, guide hollow plate, air filter body, hollow support platform and connection port, the air filter body will be guided by the guide hollow plate during the downward process, and the part of the air filter body connected to the connection port will enter the circular groove of the support frame. This avoids the difficulty in accurately placing the part of the air filter body connected to the connection port in the circular groove of the support frame, which would lead to the air filter body and the connection port being difficult to align. This would cause the two to misalign, resulting in gaps at the connection point, uneven force on the contact point, excessive local extrusion force and deformation. Even if they are accurately aligned later, they cannot achieve effective sealing and connection, resulting in permanent structural damage. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Please see Figures 1-9One embodiment of the present invention is as follows: an ultra-high pressure miniature air filter, comprising a control box body 1, with two hinged doors 101 on each side of the control box body 1, handles 102 on the sides of each of the multiple doors 101, pressure displays 103 on the sides of each of the multiple doors 101, an adjuster 105 on the side of one of the doors 101, casters 104 on the bottom of the control box body 1, a hollow support platform 2 fixed to the bottom of the inner wall of the control box body 1, a connection port 201 on the top of the hollow support platform 2, and an L-shaped tube 3 fixedly passing through the side of the hollow support platform 2. An air outlet block 4 is fixed at one end of the hollow support platform 2. The air outlet block 4 is placed above the control box body 1. A fixing block 5 is fixed at the bottom of the inner wall of the control box body 1. A motor 6 is fixed at the side of the fixing block 5. A threaded rod 7 is fixed to the output shaft of the motor 6. A threaded sleeve 8 is threadedly connected to the outer wall of the threaded rod 7. A support plate 10 is fixed to the top of the threaded sleeve 8. A placement rack 11 is fixed to the bottom of the support plate 10. Two sets of air filter bodies 1101 are placed on the inner wall of the placement rack 11. Each set of air filter bodies 1101 has six bodies. A long block 12 is fixed to the bottom of the placement rack 11. A support frame 1 is fixed to the bottom of the long block 12. 3. U-shaped track plates 14 are fixed on both sides of the hollow support platform 2. A support assembly is provided at the bottom of the inner wall of the control box body 1. The side of the support plate 10 away from the threaded sleeve 8 is fixed on the moving end of the support assembly. A hydraulic rod 202 is fixed at the top of the inner wall of the control box body 1. A pressing plate 203 is fixed at the bottom of the telescopic end of the hydraulic rod 202. Circular grooves for inserting the bottom pipe of the air filter body 1101 are opened on both sides of the top of the support frame 13. The bottom of the support frame 13 is in contact with the inner wall of the track of the U-shaped track plate 14. The support assembly includes a support block 21 fixed at the bottom of the inner wall of the control box body 1. The side of the support block 21... A long rod 2101 is fixed, and a slider 2102 is slidably installed on the outer wall of the long rod 2101. The slider 2102 is the moving end of the support component. With the above structure, the telescopic end of the hydraulic rod 202 drives the pressing plate 203 to press the second set of air filter bodies 1101, thereby realizing the switching of the two sets of air filter bodies 1101. This avoids the problem that when the air filter body 1101 needs to be stopped and the filter element of the air filter body 1101 needs to be replaced, the equipment connected to the air filter body 1101 will stop working, which will reduce the working efficiency of the connected equipment.
[0022] Positioning blocks 22 are provided on both sides of the threaded sleeve 8 and the slider 2102. Four L-shaped blocks 23 are provided on the side of the hollow support platform 2. The four L-shaped blocks 23 are located on the displacement trajectory of each positioning block 22. With the above structure, the air filter body 1101 of the second group is located at the connection port 201 of the hollow support platform 2, realizing the positioning of the air filter body 1101 of the second group and the connection port 201 of the hollow support platform 2, and avoiding the problem of deviation between the air filter body 1101 of the second group and the connection port 201.
[0023] An electric push rod 15 is fixed to the inner wall of the hollow support platform 2. A push frame 16 is fixed to the telescopic end of the electric push rod 15. A rubber ring 17 is fixed to the top of the push frame 16. A retaining ring 18 is fixed to the top of the rubber ring 17. An L-shaped stop block 19 is fixed to the top of the hollow support platform 2. The L-shaped stop block 19 is located on the displacement trajectory of the retaining ring 18. A placement groove 20 for placing the push frame 16, the rubber ring 17, and the retaining ring 18 is opened on the top of the hollow support platform 2. With the above structure, when the retaining ring 18 moves to the L-shaped stop block 19, it will be blocked by the L-shaped stop block 19 and cannot move. At this time, the push frame 16 will continue to move and squeeze the rubber ring 17, thereby deforming the rubber ring 17. The deformation of the rubber ring 17 will seal the connection port 201 between the second air filter body 1101 and the hollow support platform 2.
[0024] In use, after the first set of air filter bodies 1101 has been used for a long time, the operator activates the electric push rod 15. The telescopic end of the electric push rod 15 will drive the push frame 16, rubber ring 17, and retaining ring 18 to move downwards and into the placement slot 20. Simultaneously, the hydraulic rod 202 is activated, causing its telescopic end to move the pressing plate 203 to stop pressing the first set of air filter bodies 1101. Then, the motor 6 is activated, and the output shaft of the motor 6 will drive the threaded rod 7 to rotate. The movement of the threaded rod 7 will drive the threaded sleeve 8 to move, and the movement of the threaded sleeve 8 will... The support plate 10 moves, causing the slider 2102 to slide along the outer wall of the long rod 2101. Simultaneously, the movement of the support plate 10 moves the placement frame 11, which in turn moves the long block 12. The movement of the long block 12 then moves the support frame 13 along the inner wall of the U-shaped track plate 14. Therefore, the movement of the placement frame 11 and the support frame 13 causes the first air filter body 1101 to move away from the connection port 201 of the hollow support platform 2. At the same time, the support frame 13 moves towards the connection port 201. The system blocks the flow of air and moves the second set of air filter bodies 1101 to the connection port 201 of the hollow support platform 2. At this point, the hydraulic rod 202 is activated, causing its extension end to drive the pressing plate 203 to press the second set of air filter bodies 1101. This achieves the switching between the two sets of air filter bodies 1101, avoiding the need to stop using the air filter bodies 1101. Furthermore, replacing the filter element of the air filter body 1101 would cause the equipment connected to it to stop operating, thus preventing disruption to the connected equipment's operation. To address the issue of reduced efficiency, when the threaded sleeve 8 and slider 2102 move, the movement of the threaded sleeve 8 and slider 2102 will drive the positioning block 22 to move. Therefore, when the positioning block 22 abuts against the L-shaped block 23 during its movement, the motor 6 is turned off. At this time, the air filter body 1101 of the second group is located at the connection port 201 of the hollow support platform 2, thus achieving the positioning of the air filter body 1101 of the second group with the connection port 201 of the hollow support platform 2, and avoiding the problem of deviation between the air filter body 1101 of the second group and the connection port 201.
[0025] After the air filter body 1101 of the second group is aligned with the connection port 201, the electric push rod 15 is activated. The telescopic end of the electric push rod 15 will drive the push frame 16, rubber ring 17, and retaining ring 18 to move upward. When the retaining ring 18 moves to the L-shaped stop 19, it will be blocked by the L-shaped stop 19 and cannot move. At this time, the push frame 16 will continue to move and squeeze the rubber ring 17, thereby deforming the rubber ring 17. The deformation of the rubber ring 17 will seal the connection port 201 between the air filter body 1101 of the second group and the hollow support platform 2.
[0026] Then, open the switch door 101 to replace the filter element of the first air filter body 1101. When the first air filter body 1101 needs to be used, repeat the above operation. The initial position of the first air filter body 1101 is at the connection port 201 of the hollow support platform 2.
[0027] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, an auxiliary device 9 is provided on the top of the push frame 16. The auxiliary device 9 includes two irregularly shaped plates 91, the bottoms of which are fixed to the top of the push frame 16. A vertical rod 92 is fixed to the top of each of the two irregularly shaped plates 91. A support rod 93 is hinged to the top of the vertical rod 92. An arc block 94 is fixed to the top of the support rod 93. A spring 95 is provided between the arc block 94 and the irregularly shaped plate 91. A limit block 96 is fixed to the side of the U-shaped track plate 14. A support for the U-shaped track plate 14 is fixed to the side of the limit block 96. With the above-mentioned structure, the air filter body 1101 rests against the inner wall of the support arc plate 97, thus placing the air filter body 1101 in an inclined state. The inclined state of the air filter body 1101 makes it easier for the staff to remove the air filter body 1101 from the control box body 1. At the same time, the inclined state breaks the spatial limitation of vertical picking and placing. When putting it in, gravity can be used to push it in smoothly, reducing the action of repeatedly adjusting the position and greatly shortening the operation time of a single replacement.
[0028] A fixing plate 98 is fixed to the top of the support plate 10. Elastic telescopic rods 99 are fixed to both sides of the fixing plate 98. Multiple thin rods 910 are fixed to the telescopic ends of the elastic telescopic rods 99. With the above structure, the elastic telescopic rods 99 can make the upward-moving air filter body 1101 always tilt towards the support arc plate 97.
[0029] Two guide hollow discs 911 are fixed at the top of the support frame 13. The central hollow ring of the guide hollow disc 911 is equal to the radius of the circular groove of the support frame 13. With the above structure, as the air filter body 1101 moves downward, under the guidance of the guide hollow disc 911, the part of the air filter body 1101 connected to the connection port 201 will enter the circular groove of the support frame 13. This avoids the air filter body 1101 and the connection port 201 being difficult to place accurately in the circular groove of the support frame 13, which would lead to the air filter body 1101 and the connection port 201 being difficult to align. This would cause the two to misalign, resulting in gaps at the connection, uneven force on the contact area, excessive local extrusion force, and deformation. Even if they are accurately aligned later, they cannot achieve effective sealing and connection, resulting in permanent structural damage.
[0030] In use, as the pusher 16 moves downward, it also moves the shaped plate 91 downward. The downward movement of the shaped plate 91 moves the vertical rod 92 downward. The downward movement of the vertical rod 92, through the support rod 93 and spring 95, moves the arc block 94 downward. Simultaneously, under the tension of the spring 95, the arc opening of the arc block 94 always faces the air filter body 1101. Therefore, when switching between the first and second sets of air filter bodies 1101, the air filter body 1101 leaving the connection port 201 will move to the arc block 94, which will support the air filter body 1101. When the pusher 16 moves upward, it moves the shaped plate 91 upward, which in turn moves the vertical rod 92 upward. The downward movement of the vertical rod 92, through the support rod 93 and spring 95, moves the arc block 94 downward. As the air filter body 1101 moves upward, the arc block 94 pushes it upward. Simultaneously, during this movement, the elastic telescopic rod 99 uses its own elasticity to push the air filter body 1101 towards the supporting arc plate 97 via the thin rod 910, causing the air filter body 1101 to rest against the inner wall of the supporting arc plate 97. This tilts the air filter body 1101, making it easier for staff to remove it from the control box body 1. The tilted position also breaks the spatial limitation of vertical removal and placement, allowing it to be pushed in by gravity, reducing repeated adjustments and significantly shortening the operation time for each replacement. Furthermore, the elastic telescopic rod 99 ensures that the upward-moving air filter body 1101 always tilts towards the supporting arc plate 97.When the operator places the air filter body 1101 onto the placement rack 11, the operator first places the air filter body 1101 against the inner wall of the supporting arc plate 97. Then, under its own weight, the air filter body 1101 will abut against the top of the arc block 94, causing the arc block 94 to tilt. The tilting of the arc block 94 will cause the spring 95 to deform and the support rod 93 to rotate along the upper part of the outer wall of the vertical rod 92. When the pusher 16 moves downward, it will drive the irregular plate 91 to move downward. The downward movement of the irregular plate 91 will drive the vertical rod 92 to move downward. The downward movement of the vertical rod 92 will drive the arc block 94 to move downward through the support rod 93 and the spring 95. At the same time, under the tension of the spring 95 and the weight of the air filter body 1101 itself, the air filter body... 1101 moves downwards following the arc block 94, compressing the elastic telescopic rod 99 and causing the air filter body 1101 to enter the placement rack 11. Simultaneously, as the air filter body 1101 descends, guided by the guide hollow disc 911, the portion connecting it to the connection port 201 enters the circular groove of the support frame 13. This prevents the air filter body 1101 from being misaligned with the connection port 201, leading to gaps at the connection point, uneven stress, and excessive localized pressure causing deformation. Even with subsequent precise alignment, effective sealing and connection cannot be achieved, resulting in permanent structural damage.
[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
