Description

Technical Field

[0001] This invention belongs to the field of mask testing technology, specifically an energy-saving circulating filtration efficiency tester. Background Technology

[0002] A filtration efficiency tester is a precision instrument used to measure the ability of filter materials (such as filter cartridges, filter cloths, masks, etc.) to retain specific particulate matter. Its core principle is to simulate polluted air passing through the test material by generating a test aerosol of known concentration, and then comparing the change in particulate matter concentration before and after passing through the material to calculate the filtration efficiency of the material.

[0003] Patent CN221899019U discloses a particle filtration efficiency tester, specifically relating to the field of mask testing technology. The tester includes a main body for testing mask filtration efficiency. A vacuum pump for regulating airflow is located at the top of the main body. A first detection port is located at the bottom of the vacuum pump, and a second detection port is positioned opposite the first detection port at a relatively lower position. Fixing mechanisms are located on both sides of the second detection port, and each fixing mechanism includes two sets of oppositely positioned bases located on both sides of the second detection port. A groove is formed on the inner wall of one side of each base, and a clamping plate moves vertically within the groove. This patent allows the mask to be placed between the first and second detection ports, and the fixing mechanisms on both sides of the second detection port clamp and fix the mask, thus tightening it and preventing wrinkles when the mask is squeezed between the two sets of detection ports, thereby ensuring the authenticity of the mask's particle filtration efficiency data.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: When testing the filtration efficiency of a mask, the mask is placed between the upper and lower testing ports, and the upper testing port is driven to move down and press against the lower testing port, thereby clamping the mask for testing.

[0005] To reduce the impact of mask wrinkles on test results, two clamps are used to hold the mask at both ends before testing. These clamps are then moved in opposite directions to attempt to smooth out the wrinkles through lateral stretching. However, when the wrinkles on the mask are unevenly distributed or have complex shapes, this single lateral stretching method often fails to completely eliminate all wrinkles. Instead, it may cause stress concentration, creating new wrinkles or deepening existing ones in certain areas (such as the center of the mask or the bridge of the nose), ultimately interfering with the accuracy of the test results.

[0012] Preferably, a motor is fixedly connected to one side of the upper end of the smoothing rod, and the output end of the motor is fixedly connected to one end of the roller.

[0013] Preferably, it also includes mask recycling auxiliary components; The mask recycling auxiliary component includes slide rods fixedly connected to both ends of one side of the lifting ring. A transverse plate is slidably connected to the slide rods. An adjustment plate is slidably connected to one side of the transverse plate.

[0017] The beneficial effects of this invention are as follows: 1. The energy-saving circulating filtration efficiency tester of this invention utilizes a radially expanding wrinkle-smoothing component. Before the test begins, multiple smoothing rods and the bottom of the smoothing cloth are driven to adhere to the central area of ​​the mask. Subsequently, through the coordinated action of the smoothing rods and the smoothing cloth, a dynamic barrier is formed, starting from the center of the mask, moving outward along its surface, and continuously expanding in volume. This radial expansion process of the barrier is essentially a "smoothing wave" uniformly transmitted from the inside out. This force originates from the root of wrinkle formation, more thoroughly and evenly pushing and eliminating wrinkles to the edges. Compared to the traditional transverse stretching method, this solution fundamentally avoids the risk of exacerbating local wrinkles due to uneven stress, thereby effectively eliminating test errors caused by wrinkles and ensuring the accuracy of the test results.

[0018] 2. The energy-saving circulating filtration efficiency tester of this invention utilizes a mask recycling auxiliary component, which can compress the mask volume after testing through the coordinated action of a barrier, compression plate, and support plate. This not only effectively reduces its storage space occupation but also facilitates subsequent centralized processing.

[0019] 3. The energy-saving circulating filtration efficiency tester of the present invention, during the test, the downstream gas after the test is purified by a high-efficiency filter and then guided back to the upstream to participate in the test, realizing the multiple recycling of the test aerosol, reducing the consumption of the test medium, and is more energy-efficient.

[0024] Please refer to Figures 1-10The present invention provides a technical solution: an energy-saving circulating filtration efficiency tester, including a tester body 1, a detection port 4 on one side of the upper end of the tester body 1, a stand 2 fixedly connected to one side of the upper end of the tester body 1, an electric push rod 36 fixedly connected to one side of the stand 2, a detection port 3 fixedly connected to the piston end of the electric push rod 36, and a mask positioning component is also provided on the tester body 1.

A clamping block 32 is fixedly connected to the piston end of cylinder 31, and a pressure block 33 is slidably connected to the groove of clamping block 32. The platform 2 is also equipped with a radially expanding wrinkle-smoothing component; The radial expansion wrinkle smoothing assembly includes a lifting ring 9 slidably connected to one side of the frame 2. The lifting ring 9 is evenly distributed circumferentially and slidably connected to multiple radial rods 14. One end of each radial rod 14 is fixedly connected to a smoothing rod 23. Rollers 8 are rotatably arranged at both ends of the inner cavity of the smoothing rod 23. A smoothing cloth 30 is wound on the roller 8. The smoothing cloth 30 passes through one side of the smoothing rod 23, and the end of the smoothing cloth 30 is fixedly connected to the other side of the smoothing rod 23.

[0025] In this embodiment, as Figures 2-5 , Figures 8-10 As shown, a support plate 5 is slidably connected to one side of the upper end of the tester body 1, and a threaded rod 7 is threadedly connected to one side of the bottom of the support plate 5. Both ends of the threaded rod 7 are rotatably mounted on the tester body 1. A motor 6 is fixedly connected to one side of the upper end of the tester body 1, and the output end of the motor 6 is fixedly connected to one end of the threaded rod 7.

[0026] One side of the pressure block 33 is threadedly connected to a threaded rod 35. Both ends of the threaded rod 35 are rotatably mounted on the clamping block 32. One side of the clamping block 32 is fixedly connected to a motor 34. The output end of the motor 34 is fixedly connected to one end of the threaded rod 35.

[0027] A threaded rod 11 is threadedly connected to one side of the lifting ring 9. Both ends of the threaded rod 11 are rotatably mounted on the frame 2. A motor 10 is fixedly connected to one side of the frame 2. The output end of the motor 10 is fixedly connected to one end of the threaded rod 11.

[0028] A connecting rod 13 is rotatably mounted on one end of the radial rod 14. A transmission ring 12 is rotatably mounted on one side of the outer ring of the lifting ring 9. One end of the connecting rod 13 is rotatably mounted on the transmission ring 12. One end of the radial rod 14 is threadedly connected to a threaded rod 19. One end of the threaded rod 19 is rotatably mounted on the lifting ring 9. A motor 22 is fixedly connected to one side of the lifting ring 9. The output end of the motor 22 is fixedly connected to one end of the threaded rod 19.

[0029] A motor 37 is fixedly connected to one side of the upper end of the smoothing rod 23, and the output end of the motor 37 is fixedly connected to one end of the roller 8.

[0030] Specifically, in existing technologies, when testing the filtration efficiency of a mask, the mask is placed between two testing ports, and the upper testing port is driven to move down and press against the lower testing port, thereby clamping the mask for testing.

[0031] To reduce the impact of mask wrinkles on test results, existing technologies use two clamps to hold the mask at both ends before testing, then drive the two clamps to move in opposite directions, attempting to smooth out the wrinkles through lateral stretching. However, when the wrinkles on the mask are unevenly distributed or have complex shapes, this single lateral stretching method often fails to completely eliminate all wrinkles. Instead, it may cause stress concentration, creating new wrinkles or deepening existing ones in certain areas such as the center of the mask or the bridge of the nose, ultimately still interfering with the accuracy of the test results.

[0032] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, based on the length of the mask to be tested, the cylinders 31 on both sides drive the clamping blocks 32 to move laterally, adjust the distance between the two clamping blocks 32, and place both ends of the mask on the clamping blocks 32. Then, the motor 34 drives the threaded rod 35 to rotate, causing the pressure block 33 to descend and clamp both ends of the mask. In the initial state, the support plate 5 is in contact with the upper surface of the detection port 2 4, and the multiple smoothing rods 23 are in a clustered state. Then, the motor 2 10 drives the threaded rod 2 11 to rotate, causing the lifting ring 9 to descend until the lower ends of the multiple smoothing rods 23 simultaneously contact the mask, pressing the middle of the mask onto the support plate 5. Subsequently, the motor 4 22 drives the threaded rod 4 19 to rotate, and under the transmission cooperation of the connecting rod 1 13 and the transmission ring 12, the multiple radial rods 14 slide radially simultaneously. At the same time, the motor 7 37 drives the roller 8 to rotate, unwinding the smoothing cloth 30, so that the part of the smoothing cloth 30 outside the smoothing rods 23 always remains taut. Thus, with the mutual cooperation of the smoothing rods 23 and the smoothing cloth 30, a barrier that moves along the surface of the mask and continuously expands in volume is formed. Furthermore, the barrier expands outward from the center of the mask, which can smooth out wrinkles evenly from the inside out. Compared to stretching the mask horizontally to eliminate wrinkles, this method applies force from the center area of ​​the mask outward, like a "flat wave" radiating from the inside out, which can push wrinkles to the edge and eliminate them more thoroughly and evenly.

[0033] Once the multiple smoothing rods 23 move to the edge of the second detection port 4, the motor 6 drives the threaded rod 7 to rotate, causing the support plate 5 to move laterally and away from above the second detection port 4. Then, the electric push rod 36 lowers the first detection port 3, allowing it to pass through the barrier and press the mask firmly onto the upper surface of the second detection port 4. The filtration efficiency test can then begin. This testing process is existing technology and will not be elaborated further here. Because the wrinkles on the mask are evenly removed, the influence of wrinkles on the test results is avoided, thus ensuring the accuracy of the test results.

[0034] In addition, during the test, the downstream gas after testing is purified by a high-efficiency filter and then returned to the upstream to participate in the test, realizing the multiple recycling of the test aerosol, reducing the consumption of test media, and saving energy.

[0035] In this embodiment, as Figures 4-7 As shown, it also includes a mask recycling auxiliary component; The mask recycling auxiliary component includes slide rods 15 fixedly connected to both ends of one side of the lifting ring 9. A transverse plate 16 is slidably connected to the slide rods 15. An adjusting plate 20 is slidably connected to one side of the transverse plate 16. Cylinder 3 24 and Cylinder 4 25 are fixedly connected to both sides of the upper surface of the adjusting plate 20, respectively. A connecting block 28 is fixedly connected to the piston end of Cylinder 3 24. Two grippers 27 are rotatably arranged on one side of the connecting block 28. A compression plate 26 is fixedly connected to the piston end of Cylinder 4 25.

[0036] One end of the transverse plate 16 is threadedly connected to a threaded rod 17. Both ends of the threaded rod 17 are rotatably mounted on the lifting ring 9. A motor 18 is fixedly connected to one side of the lifting ring 9. The output end of the motor 18 is fixedly connected to one end of the threaded rod 17.

[0037] Motor 29 is fixedly connected to both sides of the connecting block 28, and the output end of motor 29 is fixedly connected to one end of the gripper 27.

[0038] A cylinder 21 is fixedly connected to one side of the transverse plate 16, and the piston end of the cylinder 21 is fixedly connected to one side of the adjusting plate 20.

[0039] Specifically, in the above embodiments, although the wrinkles on the mask can be uniformly eliminated, the mask is considered experimental waste after testing and needs to be recycled. Normally, discarded masks are placed in collection containers, but after being smoothed out, the masks increase in volume. When a large number of masks are tested, the discarded masks will take up considerable storage space in the container, affecting storage capacity and hindering subsequent centralized processing.

[0040] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: After the mask completes the test, the detection port 3 is driven to rise. Then, the threaded rod 17 is rotated by the motor 18, causing the transverse plate 16 to move laterally on the slide rod 15, aligning the two grippers 27 with the center area of ​​the mask. Then, the connecting block 28 is lowered by the cylinder 24, so that the grippers 27 contact the mask. Then, the grippers 27 are rotated by the motor 29, and the two grippers 27 clamp the mask. Subsequently, the barrier composed of the smoothing rod 23 and the smoothing cloth 30 is reduced to its minimum size. At this time, the grippers 27 are located in the inner cavity of the barrier. Then, the grippers 27 are driven to rise. When the grippers 27 rise, the mask will enter the barrier, and the mask will shrink in size as it enters the barrier, until the mask is completely inside the barrier. Then, the support plate 5 is moved laterally again to align with the upper surface of the detection port 4. The gripper 27 then releases the mask, and cylinder 21 moves the adjusting plate 20 laterally, aligning the compression plate 26 with the mask inside the enclosure. Cylinder 4 25 then lowers the compression plate 26, squeezing the mask within the enclosure. Through the coordinated action of the enclosure, compression plate 26, and support plate 5, the mask's volume is reduced. The enclosure is then moved away from the mask, and the operator places the mask in a collection container. Because the mask's volume is reduced, the storage space occupied by the mask is decreased, and it facilitates the subsequent centralized processing of multiple masks.

[0041] Working principle: First, based on the length of the mask to be tested, the cylinders 31 on both sides drive the clamping blocks 32 to move laterally, adjust the distance between the two clamping blocks 32, and place both ends of the mask on the clamping blocks 32. Then, the motor 34 drives the threaded rod 35 to rotate, causing the pressure block 33 to descend and clamp both ends of the mask. In the initial state, the support plate 5 is in contact with the upper surface of the detection port 2 4, and the multiple smoothing rods 23 are in a clustered state. Then, the motor 2 10 drives the threaded rod 2 11 to rotate, causing the lifting ring 9 to descend until the lower ends of the multiple smoothing rods 23 simultaneously contact the mask, pressing the middle of the mask onto the support plate 5. Subsequently, the motor 4 22 drives the threaded rod 4 19 to rotate, and under the transmission cooperation of the connecting rod 1 13 and the transmission ring 12, the multiple radial rods 14 slide radially simultaneously. At the same time, the motor 7 37 drives the roller 8 to rotate, unwinding the smoothing cloth 30, so that the part of the smoothing cloth 30 outside the smoothing rods 23 always remains taut. Thus, with the mutual cooperation of the smoothing rods 23 and the smoothing cloth 30, a barrier that moves along the surface of the mask and continuously expands in volume is formed. Furthermore, the barrier expands outward from the center of the mask, smoothing out wrinkles evenly from the inside out. Compared to stretching the mask laterally to eliminate wrinkles, this method applies force from the center outward, like a "flattening wave" radiating outward, more thoroughly and evenly pushing wrinkles to the edges and eliminating them. Once the smoothing rods 23 move to the edge of the second detection port 4, the motor 6 drives the threaded rod 7 to rotate, causing the support plate 5 to move laterally and away from above the second detection port 4. Then, the electric push rod 36 lowers the first detection port 3, allowing it to pass through the barrier and press the mask firmly onto the upper surface of the second detection port 4, thus initiating the filtration efficiency test. This testing process is existing technology and will not be elaborated further here. Because the wrinkles on the mask are evenly removed, the wrinkles do not affect the test results, thus ensuring the accuracy of the test results. Furthermore, during the testing process, the downstream gas after testing is purified by a high-efficiency filter and then guided back upstream to participate in the testing, realizing multiple recycling of the test aerosol, reducing the consumption of test media, and saving energy. After the mask completes the test, the detection port 3 is driven to rise, and then the threaded rod 17 is rotated by the motor 18, causing the transverse plate 16 to move laterally on the slide rod 15, so that the two grippers 27 are aligned with the center area of ​​the mask. Then, the connecting block 28 is driven to fall by the cylinder 24, so that the grippers 27 contact the mask. Then, the grippers 27 are rotated by the motor 29, and the two grippers 27 clamp the mask. Subsequently, the enclosure composed of the smoothing rod 23 and the smoothing cloth 30 is reduced to its minimum. At this time, the grippers 27 are located in the inner cavity of the enclosure. Then, the grippers 27 are driven to rise. When the grippers 27 rise, the mask will enter the enclosure, and the mask will shrink in volume as it enters the enclosure until the mask is completely inside the enclosure.Then, the support plate 5 is moved laterally again to align with the upper surface of the detection port 4. The gripper 27 then releases the mask, and cylinder 21 moves the adjusting plate 20 laterally, aligning the compression plate 26 with the mask inside the enclosure. Cylinder 4 25 then lowers the compression plate 26, squeezing the mask within the enclosure. Through the coordinated action of the enclosure, compression plate 26, and support plate 5, the mask's volume is reduced. The enclosure is then moved away from the mask, and the operator places the mask in a collection container. Because the mask's volume is reduced, the storage space occupied by the mask is decreased, and it facilitates the subsequent centralized processing of multiple masks.
