Description

Technical Field

[0001] The present invention belongs to the technical field of air purification, and particularly relates to a fully automatic air purifier for a biomedical laboratory. Background Art

[0002] In the field of biomedicine, air purification in laboratories is an important link to ensure the accuracy of experimental data and the health of researchers. Traditional air purification methods rely on simple air filtration technologies, such as using HEPA (High Efficiency Particulate Air) and ULPA (Ultra Low Penetration Air) filters of various grades. Although these methods can remove some particulate matter in the air to a certain extent, their removal effects on microorganisms and volatile organic compounds are limited and cannot meet the requirements for high-cleanliness air in biomedical laboratories.

[0003] In recent years, with the continuous improvement of antibacterial purification technology and environmental protection requirements, more and more biomedical laboratories have begun to adopt advanced air purifiers. These new purifiers can not only effectively remove particulate matter and microorganisms in the air, but also have made remarkable progress in reducing energy consumption and improving purification efficiency. Especially in highly sensitive scientific research such as pharmaceuticals, bioengineering, and gene editing, such air purifiers that can provide higher cleanliness are of irreplaceable importance. This not only improves the reliability of experimental results, but also greatly reduces the experimental risks caused by environmental pollution or microorganisms in the air.

[0004] However, in biomedical laboratories in universities or research institutes, a large number of biomedical experiments are carried out every day, and there will inevitably be operational errors, resulting in the leakage of dangerous chemicals, which is also one of the main reasons for the relatively high risks in biomedical experiments. Once the leaked dangerous chemicals volatilize and diffuse into the air, it will cause serious air pollution. Since it is difficult for the air purifier to remove them in time, it seriously endangers the health of experimental personnel.

[0022] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 - 13 shown, a fully automatic air purifier for a biomedical laboratory in an embodiment of the present invention includes a bracket 11, a gas monitor 40, an air purification chassis 50, an isolation ring 60, and a suction mechanism.

[0024] A test bench 10 is installed in the biomedical laboratory. The bracket 11 is fixedly installed at the rear end of the test bench 10. The first slide rail 20 and the second slide rail 30 are fixedly installed on the bracket 11. Both the first slide rail 20 and the second slide rail 30 are made of I-beams and have sufficient structural strength. A second electric slider 31 is slidably installed on the second slide rail 30. The second electric slider 31 can automatically walk and move on the first slide rail 20. A gas monitor 40 is fixedly installed at the front end of the second electric slider 31. The second electric slider 31 can drive the gas monitor 40 to horizontally slide on the second slide rail 30.

[0025] Specifically, the gas monitor 40 can monitor the air quality above the experimental bench 10 in real time, and the gas monitor 40 can reciprocate on the second slide rail 30 for monitoring, realizing back-and-forth cruising, so as to be able to timely and accurately detect the leakage location of dangerous chemicals.

[0026] A first electric slider 21 is slidably installed on the first slide rail 20. The first electric slider 21 can automatically move on the first slide rail 20. The top end of the first electric slider 21 is fixedly installed with an air purification chassis 50. The first electric slider 21 can drive the air purification chassis 50 to slide horizontally on the first slide rail 20.

[0027] As Figure 3 shown, a fan 501 and a multi-layer filter assembly 502 are fixedly installed inside the air purification chassis 50. The fan 501 is used to draw air into the air purification chassis 50, and the multi-layer filter assembly 502 is used to filter and purify the air. Among them, the multi-layer filter assembly 502 includes but is not limited to HEPA filters, activated carbon filters, titanium-gold sterilization nets, and cold catalyst decomposition nets, etc., which can efficiently filter and purify the air in the biological medicine laboratory.

[0028] As Figure 1 and Figure 4 shown, an air outlet 51 is fixedly installed on one side of the air purification chassis 50. The air outlet 51 is used for discharging the air after purification; a fresh air hose 52 is fixedly installed on the top end of the air purification chassis 50. The fresh air hose 52 is connected to the fresh air system and is used to provide a continuous supply of fresh air for the biological medicine laboratory. An extension plate 53 is fixedly installed at the front end of the air purification chassis 50. The extension plate 53 is located directly above the experimental bench 10. An air inlet seat 54 is fixedly installed on the lower end surface of the extension plate 53. Air inlet holes 541 are evenly formed in the air inlet seat 54. Among them, the extension plate 53 is communicated with the inside of the air purification chassis 50, and the air inlet seat 54 is communicated with the inside of the extension plate 53, that is, the external air can be first drawn into the inside of the air inlet seat 54 through a plurality of air inlet holes 541, and then enter the inside of the air purification chassis 50 through the extension plate 53.

[0029] Specifically, under normal operating conditions, the air in the biological medicine laboratory is drawn into the air purification chassis 50 by the fan 501 through a plurality of air inlet holes 541, and after being filtered and purified by the multi-layer filter assembly 502 inside the air purification chassis 50, it is discharged through the air outlet 51, realizing the circulating filtration and purification of the air in the biological medicine laboratory.

[0030] As Figure 2As shown, the isolation ring 60 is suspended below the air inlet seat 54, and a lifting mechanism for driving the lifting of the isolation ring 60 is fixedly installed on the extension plate 53. Among them, the lifting mechanism includes a pair of winches 70, and the pair of winches 70 are fixedly installed on the lower end surface of the extension plate 53. A pair of suspension ropes 71 are fixedly installed on both sides of the isolation ring 60, and one ends of the pair of suspension ropes 71 away from the isolation ring 60 are respectively fixedly installed on the pair of winches 70. By winding the suspension ropes 71 by the winches 70, the isolation ring 60 can be lifted and lowered.

[0031] An annular air inlet 542 is provided on the lower end surface of the air inlet seat 54, and a convex ring 62 is fixedly installed at the top of the isolation ring 60. In the initial state, the isolation ring 60 is closely attached to the lower end surface of the air inlet seat 54. At this time, the convex ring 62 is inserted into the inside of the annular air inlet 542 to realize the limit of the isolation ring 60, making the structure more stable. At the same time, the isolation ring 60 can seal the annular air inlet 542.

[0032] Among them, as Figure 5 Combined with Figure 11 shown, the inside of the isolation ring 60 is a hollow structure, and an annular air outlet 621 is provided on the convex ring 62. The annular air outlet 621 is communicated with the hollow structure inside the isolation ring 60. That is, by inflating the inside of the isolation ring 60, the gas can be blown out through the annular air outlet 621.

[0033] As Figure 1 and Figure 4 shown, a duct 61 is fixedly installed on one side of the isolation ring 60. One end of the duct 61 is connected beside the air outlet 51. The purified clean air can not only be discharged through the air outlet 51, but also be introduced into the inside of the isolation ring 60 through the duct 61.

[0034] An electric butterfly valve 511 is fixedly installed on the air outlet 51. By controlling the opening and closing size of the electric butterfly valve 511, the discharge rate of the clean air through the air outlet 51 can be controlled, and indirectly the introduction rate of the clean air into the inside of the isolation ring 60 through the duct 61 can be controlled, enhancing the controllability.

[0035] By controlling the electric butterfly valve 511 to make the clean air completely blown out through the annular air outlet 621, so that the gas blown out from the annular air outlet 621 has sufficient pressure, avoiding the suction force of the upper opening 6511 of the suction mechanism or the upward air extraction of several air inlet holes 541 from affecting the formation of the air curtain, so as to ensure the formation effect of the air curtain.

[0036] In addition, a solenoid valve 611 can also be installed on the duct 61 to control the on-off of the duct 61.

[0037] Specifically, during the process of conducting biomedical experiments on the experimental bench 10, if the gas monitor 40 detects a leakage of hazardous chemicals above a certain location, the first electric slider 21 can drive the air purification chassis 50 to move above it. Then, the winch 70 releases the lifting rope 71, causing the isolation ring 60 to naturally descend under the action of gravity. At this time, the solenoid valve 611 is opened, enabling the purified clean air to be introduced into the interior of the isolation ring 60 through the air duct 61 and then blown out through the annular air outlet 621. At the same time, the annular air inlet 542 is also opened to allow normal air intake.

[0038] The gas blown out from the annular air outlet 621 can just be extracted by the annular air inlet 542, enabling an annular air curtain to be formed between the two. When the isolation ring 60 descends to the experimental bench 10, the annular air curtain forms a closed loop. At this time, the isolation ring 60 can enclose the area where the hazardous chemicals are leaking and isolate the hazardous chemical leakage area from the outside through the annular air curtain, preventing the hazardous chemicals from volatilizing and spreading outward. Meanwhile, the gas inside the annular air curtain is normally drawn into the interior of the air purification chassis 50 through a number of air inlet holes 541 for filtration and purification, thereby achieving targeted purification of the air inside the isolation area, effectively avoiding the outward diffusion of the leaked hazardous chemicals, and protecting the laboratory environment and the health of the experimental personnel.

[0039] In the biomedical laboratories of universities or research institutes, the application of this air purifier can ensure the safety and health of teachers, students, or researchers in universities, so that they can conduct experimental research safely and with confidence, and greatly reduce the risks of biomedical experiments.

[0040] It should be noted that, as Figure 6 shown, a ring-shaped ultraviolet lamp 63 is also fixedly installed on the lower end surface of the isolation ring 60. The ring-shaped ultraviolet lamp 63 can emit a ring-shaped ultraviolet light circle. Using the ultraviolet sterilization technology, the isolation ring 60 can prevent the diffusion and spread of leaked bacteria, viruses, and other microorganisms.

[0041] Specifically, since biomedical experiments inevitably involve the use of microorganisms, if a microorganism leakage occurs, the isolation ring 60 does not need to descend. Only the ring-shaped ultraviolet lamp 63 below the isolation ring 60 emits an ultraviolet light circle, and the microorganism leakage area is enclosed by the ultraviolet light circle to prevent the diffusion and spread of microorganisms.

[0042] As Figure 5 and Figure 6 shown, a cross beam 64 is fixedly installed on the isolation ring 60. At the center position of the top end of the cross beam 64, a driving motor 65 is fixedly installed. The output end of the driving motor 65 is fixedly installed with a rotating shaft 651. The bottom end of the rotating shaft 651 penetrates below the cross beam 64 and is fixedly installed with a cleaning component 66. The driving motor 65 can drive the cleaning component 66 to rotate, realizing the automatic cleaning of the leaked hazardous chemicals on the experimental bench 10.

[0043] Among them, as Figures 8 - 10 shown, the cleaning component 66 includes a main pipe body 661 and a secondary pipe body 662. The secondary pipe body 662 is fixed to the rotating shaft 651. One end of the main pipe body 661 is fixedly installed with a connecting pipe 665. The connecting pipe 665 is inserted into the interior of the secondary pipe body 662, and the connecting pipe 665 can rotate inside the secondary pipe body 662, that is, the main pipe body 661 can rotate relative to the secondary pipe body 662.

[0044] One end of the connecting pipe 665 is provided with a plurality of slot grooves 6651. A plurality of inner grooves 6621 are provided on the inner wall of the secondary pipe body 662. A plurality of insertion blocks 6623 are slidably installed inside the plurality of inner grooves 6621. The insertion blocks 6623 are matched with the slot grooves 6651. After the connecting pipe 665 is inserted into the interior of the secondary pipe body 662, the plurality of insertion blocks 6623 can just be respectively inserted into the interior of the plurality of slot grooves 6651. At this time, the rotation of the connecting pipe 665 is restricted by the sliding stroke of the insertion blocks 6623 inside the inner grooves 6621, so that the main pipe body 661 can only rotate within a certain angle.

[0045] A spring 6622 is fixedly installed between the insertion block 6623 and the inner groove 6621. Through the spring 6622, the insertion block 6623 can elastically slide inside the inner groove 6621, that is, the main pipe body 661 can elastically rotate within a certain angle.

[0046] Specifically, as Figure 13 shown, when the isolation ring 60 completely descends onto the experimental table 10, the main pipe body 661 can just contact the experimental table 10. At this time, the driving motor 65 can drive the main pipe body 661 to rotate forward and backward horizontally around the rotating shaft 651. During the horizontal rotation process, due to the frictional force acting on the main pipe body 661 itself, the main pipe body 661 will also elastically rotate vertically around its central axis, that is, the main pipe body 661 can elastically rotate around its own axis.

[0047] One side of the main pipe body 661 is fixedly installed with a scraping plate 663. When the main pipe body 661 rotates vertically, the scraping plate 663 can be in close contact with the surface of the experimental table 10. Combining with the horizontal rotation of the main pipe body 661, the scraping plate 663 can scrape the dangerous chemicals leaked on the surface of the experimental table 10. A number of suction holes 6631 are provided on the scraping plate 663. The suction holes 6631 are communicated with the interior of the main pipe body 661. Through the suction holes 6631, the dangerous chemicals can be scraped and extracted at the same time, realizing the collection and cleaning of the dangerous chemicals.

[0048] Among them, as Figure 6 Combined with Figure 11As shown, a suction mechanism is also installed on the cross beam 64. The suction mechanism includes a liquid collection box 67 and a fixed seat 69. The liquid collection box 67 is fixedly installed on the cross beam 64, and a liquid pump 68 is fixedly installed on one side of the liquid collection box 67.

[0049] As Figure 12 shown, the fixed seat 69 is fixedly installed outside the rotating shaft 651. An absorption cavity 691 is arranged inside the fixed seat 69. The rotating shaft 651 penetrates through the inside of the fixed seat 69. A plurality of groups of openings 6511 are formed on the surface of the rotating shaft 651, and all the plurality of groups of openings 6511 are located inside the absorption cavity 691. The inside of the absorption cavity 691 is communicated with the inside of the rotating shaft 651 through the plurality of groups of openings 6511. The rotating shaft 651 is also communicated with the inside of the auxiliary pipe body 662, that is, the rotating shaft 651 is indirectly communicated with the inside of the main pipe body 661. Therefore, the absorption cavity 691 is communicated with the inside of the main pipe body 661.

[0050] A liquid extraction pipe 681 is fixedly installed between the input end of the liquid pump 68 and the fixed seat 69. The liquid pump 68 can extract the leaked hazardous chemicals through the liquid extraction pipe 681 and inject them into the inside of the liquid collection box 67 for collection.

[0051] Wherein, a check valve 6811 is fixedly installed on the liquid extraction pipe 681 to prevent the backflow of the hazardous chemicals injected into the inside of the liquid collection box 67.

[0052] As Figure 7 shown, a drain pipe 671 is fixedly installed on the liquid collection box 67, and the drain pipe 671 is communicated with the inside of the liquid collection box 67. A manual valve 6711 is fixedly installed on the drain pipe 671. By opening the manual valve 6711, the hazardous chemicals collected inside the liquid collection box 67 can be taken out through the drain pipe 671.

[0053] Specifically, when the scraper 663 scrapes the leaked hazardous chemicals on the test bench 10, the liquid pump 68 is started, and the hazardous chemicals can be sucked into the air duct 61 through the suction holes 6631, and then are sent into the inside of the liquid collection box 67 through the auxiliary pipe body 662, the rotating shaft 651, the absorption cavity 691 and the liquid extraction pipe 681 in sequence, so as to realize the collection and cleaning of the leaked hazardous chemicals. Manual cleaning is no longer required, and the risk of manual handling is eliminated.

[0054] As Figure 9As shown, a wiping seat 664 is also fixedly installed on the other side of the main pipe body 661. The wiping seat 664 is located on the opposite side of the scraping plate 663, and a wiping cotton 6641 is fixedly installed on the wiping seat 664. When the driving motor 65 drives the main pipe body 661 to horizontally rotate in the opposite direction compared with the above, the main pipe body 661 will also rotate in the opposite direction in the vertical direction. At this time, the wiping cotton 6641 will contact the surface of the experimental table 10. After the leaked hazardous chemicals are pumped away by the wiping cotton 6641, the surface of the experimental table 10 can be wiped and cleaned, so as to achieve secondary cleaning and ensure that the hazardous chemicals leaked on the surface of the experimental table 10 are completely cleaned up.

[0055] In addition, as Figure 13 shown, a cavity 6642 can be further provided inside the wiping seat 664, and medical alcohol is stored inside the cavity 6642. A plurality of cotton threads 6643 are fixedly installed on the wiping cotton 6641, and one end of the cotton thread 6643 extends into the cavity 6642 and is immersed in the medical alcohol. The medical alcohol inside the cavity 6642 can be slowly conducted to the wiping cotton 6641 through the cotton thread 6643, so that the wiping cotton 6641 can be used as an alcohol cotton. During the process of wiping the surface of the experimental table 10, the surface of the experimental table 10 can be further disinfected with alcohol to ensure the cleanliness of the surface of the experimental table 10 and make it safer and more reliable to use.

[0056] During use, the gas monitor 40 reciprocates on the second slide rail 30, and can monitor in real time whether there is any leakage of hazardous chemicals on the experimental table 10 during the biomedical experiment process. Once it is found that there is a situation of hazardous chemical leakage, at this time, the first electric slider 21 drives the air purification machine box 50 to move above the leakage area, and then the winch 70 releases the lifting rope 71, so that the isolation ring 6 starts to descend naturally under the action of gravity. At this time, the solenoid valve 611 is opened, so that the purified clean air can be introduced into the isolation ring 6 through the air duct 61 and blown out through the annular air outlet 621. At the same time, the annular air inlet 542 is also opened to allow normal air intake. The gas blown out by the annular air outlet 621 can just be extracted by the annular air inlet 542, so that an annular air curtain can be formed between the two. When the isolation ring 6 descends onto the experimental table 10, the annular air curtain forms a closed loop. At this time, the isolation ring 6 can enclose the area where there is a leakage of hazardous chemicals, and isolate the hazardous chemical leakage area from the outside through the annular air curtain, preventing the hazardous chemicals from volatilizing and diffusing outward. At the same time, the gas inside the annular air curtain is normally pumped into the air purification machine box 50 through a plurality of air inlet holes 541 for filtering and purification, so as to achieve targeted purification of the air inside the isolation area.

[0057] Next, when the isolation ring 60 completely descends onto the experimental table 10, the main pipe body 661 can just come into contact with the experimental table 10. At this time, the drive motor 65 can drive the main pipe body 661 to rotate forward and backward horizontally around the rotating shaft 651. During the horizontal rotation process, due to the frictional force acting on the main pipe body 661 itself, the main pipe body 661 will also undergo elastic rotation in the vertical direction around its central axis. When the main pipe body 661 rotates in the vertical direction, the scraper 663 can closely adhere to the surface of the experimental table 10. Combining with the horizontal rotation of the main pipe body 661, the scraper 663 can scrape the dangerous chemicals leaked on the surface of the experimental table 10. At the same time, the liquid pump 68 is started, and the dangerous chemicals can be pumped into the inside of the air duct 61 through the suction holes 6631, and then successively sent into the liquid collection box 67 through the auxiliary pipe body 662, the rotating shaft 651, the liquid suction cavity 691, and the liquid extraction pipe 681, realizing the collection and cleaning of the leaked dangerous chemicals.

[0058] Finally, change the driving direction of the drive motor 65 to drive the main pipe body 661 to rotate horizontally in the opposite direction compared to when scraping and extracting. At this time, the main pipe body 661 will also rotate in the opposite direction in the vertical direction compared to when scraping and extracting, and the wiping cotton 6641 will come into contact with the surface of the experimental table 10. After the leaked dangerous chemicals are pumped away through the wiping cotton 6641, the surface of the experimental table 10 can be wiped and cleaned, thereby realizing secondary cleaning and ensuring that the dangerous chemicals leaked on the surface of the experimental table 10 are completely cleaned.

[0059] Compared with the prior art, by real-time monitoring the air quality above the experimental table 10, the present invention can timely detect the leakage of dangerous chemicals, and through the isolation ring 60, timely isolate the leakage area, and then specifically purify the air inside the isolation area, effectively avoiding the outward diffusion of the leaked dangerous chemicals, protecting the laboratory environment and the health of experimental personnel; Through the cleaning component 66, the present invention can automatically clean the dangerous chemicals leaked on the experimental table 10 while purifying the air inside the isolation area, automatically handle the leaked dangerous chemicals, without manual handling, eliminating the risks of manual handling, and thus fully automatically coping with various situations of dangerous chemical leakage, with safe and reliable use.

[0060] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
