[0002] Paper cultural relics refer to cultural relics composed of paper, including calligraphy and painting, newspapers, archives, maps, rubbing and paper money, etc. The earliest paper cultural relics can be traced back to the Western Han Dynasty. With the development of history, the material and specific composition of paper cultural relics of different years and use fields are different, but the manufacturing raw materials are plant fibers, including cellulose, hemicellulose and lignin. With the increase of the preservation time of paper cultural relics, the paper surface will be seriously polluted, and many bacterial colonies will be bred, accelerating the aging of paper and shortening the life of paper.

[0003] The reason for the pollution on the surface of paper is that many dust in the air of the paper storage environment will be adsorbed on the surface of paper, inorganic impurities will be deposited on the surface of paper, in addition, organic particles will also adhere to the surface of paper, and some substances will even form a keying action on the surface of paper, making it difficult to remove these impurity particles by general methods. These impurity particles gather on the surface of paper, forming an inert layer, which destroys the surface morphology and structure of paper. In addition, since the main components of paper are polysaccharides, monosaccharides and aromatic polymers, they can be used as a source of nutrients for bacterial spores, so the surface of paper cultural relics is easy to produce bacterial breeding, mold covering and bookworm breeding, forming a microecological system on the surface of paper cultural relics, which may cause serious acidification of paper, fiber breakage and other problems.

[0004] The paper cultural relic disinfection device of the prior art, such as Chinese invention publication No. CN113476627A, discloses a nondestructive disinfection cleaning method for paper cultural relics, which uses air flow generated by normal pressure low temperature plasma jet to blow the surface of paper cultural relics.

[0005] However, the existing technology has some problems: the spray range of the spray head is small, and it cannot spray the parts close to the edge of the paper cultural relics, so we propose a nondestructive disinfection cleaning device for paper cultural relics. UTILITY MODEL CONTENTS

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a non-destructive disinfection and cleaning device for paper cultural relics.

[0026] It includes a main body 1, the side wall of the main body 1 is fixedly connected to a lifting and adjusting device 5, the lifting and adjusting device 5 is fixedly connected to a supporting mesh plate 4, the inner wall of the main body 1 is connected to a plasma jet device 6, the plasma jet device 6 includes a plasma jet 61, one end of the plasma jet 61 is connected to a mixed gas nozzle 63, the plasma jet 61 is fixedly connected to a mounting plate 62, the upper left side of the mounting plate 62 is connected to a first compressed air nozzle 64, and the upper right side of the mounting plate 62 is connected to a second compressed gas nozzle 66.

[0027] The first compressed air nozzle 64 and the second compressed gas nozzle 66 are respectively connected to a hose 65 , and one end of the hose 65 is connected to a solenoid valve 67 .

[0028] One end of the solenoid valve 67 is connected to a compressed air connecting pipe 68 , which passes through the rear wall of the main body 1 and is fixedly connected thereto. The compressed air connecting pipe 68 is used to connect to an air compressor or compressed gas from a factory.

[0029] The lifting and adjusting device 5 includes a transparent vertical plate 51 and a slide rail 54 . A connecting block 53 is slidably connected to the slide rail 54 to adjust the height of the connecting block 53 and the supporting mesh plate 4 .

[0030] The front side of the connecting block 53 is provided with a screw hole, and the transparent vertical plate 51 is provided with a plurality of mounting holes. The transparent vertical plate 51 is connected to the connecting block 53 by hand screws 52 , and the connecting block 53 is fixedly connected to the supporting mesh plate 4 by a connecting plate 55 .

[0031] A gap 41 is provided at the rear of the support mesh plate 4, and a gas cylinder connection port is provided at the rear of the plasma jet device 61 for connecting a gas cylinder containing a mixture of air, hydrogen and argon.

[0032] The front portion of the main body 1 is rotatably connected to a cabinet door 3 , on which a switch 2 and a power indicator light are provided.

[0033] The utility model provides a non-destructive disinfection and cleaning device for paper cultural relics. The innovation of the utility model lies in the organic combination of plasma jet technology and compressed gas injection technology, combined with the lifting and adjusting device 5, to form a highly efficient non-destructive cleaning system.

[0034] The installation of a lifting and adjusting device 5 and a supporting mesh 4 allows the device to accommodate paper artifacts of varying sizes and thicknesses. The supporting mesh 4 serves as a base platform for the artifacts, and its rear recess 41 provides the necessary space for the plasma jet, preventing jet attenuation caused by physical obstacles.

[0035] Traditional cleaning methods often have difficulty balancing the handling needs of artifacts of different sizes. The present invention solves this problem by adjusting the height of the support mesh 4. Especially for precious artifacts, the height adjustment function ensures safety and flexibility during the cleaning process, preventing unnecessary damage caused by a fixed height.

[0036] As one of the core components, the plasma jet device 6 uses plasma technology to achieve deep disinfection and cleaning of the surface of cultural relics. The high-energy particles generated by the plasma jet device 61 can effectively destroy microbial structures without damaging paper cultural relics.

[0037] Compared to traditional chemical cleaning methods, plasma jet technology avoids the risk of chemical residue, and its non-contact operation also avoids damage caused by physical friction. This is a significant advancement for fragile objects such as paper artifacts.

[0038] By providing a first compressed air nozzle 64 and a second compressed gas nozzle 66, and a matching solenoid valve 67 control system, precise control of the spray angle and force is achieved. The two nozzles can not only be used independently, but can also work in coordination with the solenoid valve 67 to meet the cleaning needs of different situations.

[0039] In traditional methods, a single nozzle often struggles to adapt to changing working environments. The present invention, by introducing a dual nozzle and solenoid valve 67 control strategy, not only improves cleaning efficiency but also enhances the system's adaptability. This design allows for more meticulous cleaning, especially on artifact surfaces with complex textures or uneven surfaces.

[0040] In summary, this utility model, through innovative integration of existing technologies, provides an efficient, safe, and flexible solution for the non-destructive disinfection and cleaning of paper artifacts. Its unique design not only reflects a high level of concern for the protection of cultural relics, but also demonstrates the important role of scientific and technological innovation in the field of cultural heritage protection.

[0041] During use, the paper artifact to be cleaned is first placed on the support mesh 4. The height of the support mesh 4 is then adjusted using the lifting and adjusting device 5 to accommodate artifacts of varying sizes and thicknesses. Several mounting holes on the transparent upright 51 mate with screw holes on the connecting block 53, which is then secured in place using hand screws 52, allowing the height of the support mesh 4 to be adjusted.

[0042] Next, open cabinet door 3 and activate the power supply via switch 2. The power indicator lights up, indicating the device is ready for use. At this point, the plasma jet device 6 begins operating. The plasma jet generated by the plasma jet generator 61 mixes with the mixed gas in the gas cylinder and is ejected through the mixed gas nozzle 63 to perform preliminary disinfection and pretreatment on the surface of the cultural relics. The plasma jet effectively kills microorganisms on the surface and initially decomposes some organic pollutants.

[0043] At the same time, either the first compressed air nozzle 64 or the second compressed air nozzle 66, or both, can be activated as needed. A solenoid valve 67 controls the flow of air from compressed air connection pipe 68 to the designated nozzle. Compressed air is delivered to the corresponding nozzle via hose 65, where it is ejected in a high-speed stream, further removing loose dirt and dust left behind by the plasma jet treatment, ensuring a clean and tidy surface for the artifact.

[0044] Throughout the entire process, the plasma jet and compressed gas jet work together, leveraging both the disinfection benefits of the plasma jet and the physical purge action of the compressed gas, achieving non-destructive cleaning of paper artifacts. Furthermore, fine adjustment of the lifting and adjusting device 5 ensures the safety and effectiveness of the entire cleaning process, protecting the artifacts from any unnecessary damage.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
