Technical Field

[0001] The utility model relates to the technical field of super clean workbenches, in particular to a medical super clean workbench. Background Art

[0002] The clean bench, also known as the purification bench, is a unidirectional air purification device that provides a local dust-free and sterile working environment. It was originally designed to meet the needs of modern industry, optoelectronics industry, biopharmaceuticals, scientific research and other fields for the cleanliness of local working areas. The main functions of the clean bench include: Improving experimental efficiency: By providing a dust-free and sterile working environment, the clean bench can reduce interference factors in the experimental process, thereby improving experimental efficiency. Ensure the accuracy and stability of experimental results: A clean working environment is crucial for many precision experiments. The clean bench can ensure the stability of experimental conditions, thereby ensuring the accuracy and reliability of experimental results. Protect the health of experimenters: The clean bench can effectively prevent experimenters from contacting harmful substances, reduce the risk of occupational diseases, and protect the health of experimenters.

[0003] However, in actual use of the prior art, during the use of the clean bench, in order to ensure the cleanliness of the clean bench work surface, an ultraviolet disinfection lamp is usually used to sterilize and disinfect the work surface. The work surface can only be used after the sterilization and disinfection is completed. However, when the ultraviolet disinfection lamp is used to sterilize and disinfect the work surface, the ultraviolet disinfection lamp requires a certain disinfection time to complete the sterilization and disinfection of the work surface, so that the work surface has a certain waiting interval time when it is reused, which affects the use efficiency of the clean bench.

However, when the ultraviolet disinfection lamp is used to sterilize and disinfect the operating table, the ultraviolet disinfection lamp needs a certain disinfection time to complete the sterilization and disinfection of the operating table, so that the operating table has a certain waiting interval time when it is repeatedly used, thereby affecting the use efficiency of the clean bench.

[0024] An operating groove 10 is provided through the middle of the upper end of the clean bench body 1, and an operating table 11 is movably connected to the inner wall of the operating groove 10. A main adjusting shaft 12 is fixedly installed through the middle of the operating table 11, and the main adjusting shaft 12 is rotatably connected to both sides of the inner wall of the operating groove 10 through a rotating shaft. A main pulley 13 is fixedly installed on the outer side of the main adjusting shaft 12, and a secondary pulley 14 is connected to the outer end of the main pulley 13 through a belt drive. A secondary adjusting shaft 15 is fixedly installed through the middle of the secondary pulley 14, and the inner side of the secondary adjusting shaft 15 is rotatably connected to the outer side wall of the upper end of the clean bench body 1, and a fastening ring 16 for locking and fastening the secondary adjusting shaft 15 is threadedly connected to the inner outer curved surface of the secondary adjusting shaft 15, and a turning handle 17 is fixedly installed on the outer side of the secondary adjusting shaft 15. The middle of the front and rear ends of the operating table 11 are opened A mounting circular groove 18 is provided, and there are two mounting circular grooves 18, which are symmetrically distributed in the middle of the front and rear ends of the operating table 11, and a telescopic spring 19 is fixedly installed on the inner end of the mounting circular groove 18.

A limiting circular groove 21 is provided on the inner wall of the front and rear ends of the operating groove 10, and the outer outer curved surface of the limiting ball 20 is movably connected to the opening of the limiting circular groove 21, so that the operating table 11 is positioned by the limiting ball 20 in cooperation with the mounting circular groove 18 and the limiting circular groove 21, and a disinfection chamber 22 is fixedly installed on the inner side of the lower end of the ultra-clean workbench main body 1, and an ultraviolet disinfection lamp 23 is fixedly installed on the bottom of the disinfection chamber 22, and the ultraviolet disinfection lamp 23 faces the lower end surface of the operating table 11.

[0025] Working principle: When in use, the utility model controls the air intake fan 6 to start. When the air intake fan 6 is turned on, the external air will be sucked into the static pressure chamber 3 through the filter screen 5 and the air intake grille 4 in sequence. When the external air is sucked into the static pressure chamber 3, under the action of the internal pressure of the static pressure chamber 3, the air will enter the filter 8. When the air enters the filter 8, the air will be purified and filtered by the filter 8, and discharged to the upper end of the clean bench body 1 through the exhaust grille 7 in the state of unidirectional horizontal airflow, so that the upper end of the clean bench body 1 maintains a cleanliness level of Class 100;

[0026] At the same time, by controlling to turn on the ultraviolet disinfection lamp 23, when the ultraviolet disinfection lamp 23 is turned on, the lower end surface of the operating table 11 will be disinfected and sterilized. When the lower end surface of the operating table 11 is disinfected and sterilized, it will not affect the normal operation and use of the upper end surface of the operating table 11. When the operation and use of the upper end surface of the operating table 11 are completed, the fastening ring 16 is loosened by rotating. When the fastening ring 16 is loosened, the auxiliary adjusting shaft 15 is driven to rotate by the turning handle 17. When the auxiliary adjusting shaft 15 rotates, it will drive the auxiliary pulley 14 to rotate. When the auxiliary pulley 14 rotates, it will drive the belt pulley 14 to rotate. The belt drive drives the main pulley 13 to rotate. When the main pulley 13 rotates, it will drive the main adjusting shaft 12 to rotate. When the main adjusting shaft 12 rotates, it will drive the upper and lower end surfaces of the operating table 11 to rotate and flip. When the upper and lower end surfaces of the operating table 11 are flipped, the lower end surface of the operating table 11 that has been disinfected with ultraviolet light before flipping can be immediately operated and used. At the same time, before flipping, the upper end surface of the operating table 11 will face the ultraviolet disinfection lamp 23 for sterilization and disinfection. Therefore, by flipping the operating table 11, the use efficiency of the operating table 11 is improved.

[0027] At the same time, when the operating table 11 rotates, the limiting ball 20 will be driven to rotate, and the outer curved surface of the limiting ball 20 is movably connected to the opening of the limiting circular groove 21, so that when the limiting ball 20 rotates, under the force of the opening of the limiting circular groove 21, the limiting ball 20 will move inwardly along the inner wall of the installation circular groove 18 and shrink. When the limiting ball 20 moves inwardly and shrinks, it will push the compressed telescopic spring 19. When the operating table 11 rotates to one hundred and eighty degrees, the limiting ball 20 will reset and move to the opening of the limiting circular groove 21 under the action of the elastic potential energy generated by the compression deformation of the telescopic spring 19, so that the upper and lower end surfaces of the operating table 11 can remain limited after being flipped one hundred and eighty degrees, thereby facilitating the flipping and positioning of the operating table 11.
