[0002] A laboratory is a place specifically used for scientific research, experimental operations, analysis and testing, teaching demonstrations and product development. It provides a controlled environment for scientists, engineers and technicians. Among them, the laboratory laminar flow clean bench, also known as a laminar flow clean bench or clean bench, is a device specifically designed to provide a local high cleanliness environment.

[0003] Currently, when using laboratory clean benches, disinfection equipment needs to be prepared in advance, which increases the workload for staff and makes it inconvenient for staff to disinfect the work surface at any time, which may delay the experimental process and increase the number of operating steps for staff. Therefore, a height-adjustable laboratory clean bench is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the disinfection equipment needs to be prepared in advance when disinfecting laboratory clean benches, which easily wastes the staff's time, and to propose a height-adjustable laboratory clean bench.

[0018] 1. In this utility model, a disinfection component is provided. The fixed box is moved by a handle on the fixed box, causing the fixed box to move onto the travel box. Simultaneously, the travel box moves the rotating rod, which in turn drives the rotating rod to rotate. The rotating rod then drives the reciprocating screw inside the travel box to rotate. When the top rod presses against the extrusion plate, the extrusion plate moves the extrusion rod on the fixed block synchronously, squeezing the disinfectant from the water bag into the water pipe. The disinfectant is then sprayed from the self-tightening nozzle on the water pipe onto the workbench surface for disinfection. This mobile disinfection method allows for rapid disinfection of the desired area, reducing preparation and disinfection time, simplifying the disinfection process, and making operation simple and convenient. It saves staff time and improves experimental efficiency.

[0030] The disinfection component 6 includes a travel box 61, a rotating rod 65, and a telescopic spring 616. A rack 63 is fixedly installed on the inner wall of the bottom surface of the travel box 61. A reciprocating lead screw 67 is provided on the outer wall of the rotating rod 65. A threaded sleeve 68 is threaded onto the outer surface of the reciprocating lead screw 67. A movable sleeve 66 is slidably installed on the side wall of the travel box 61 via a slider. The inner wall of the cavity of the movable sleeve 66 is rotatably connected to the outer wall of the rotating rod 65. A movable rod 69 is fixedly installed on the upper surface of the threaded sleeve 68. One end of the rotating rod 65 extends into the interior of the travel box 61 and is fixedly installed with a gear 64. The lower surface of the travel box 61 is fixedly connected to the upper surface of the platform 5. The gear 64 meshes with the rack 63. One end of the movable rod 69 extends beyond the upper surface of the movable sleeve 66. A top rod 610 is fixedly installed on the side wall of the movable rod 69. A support is fixedly installed on the outer wall of the movable sleeve 66. A support sleeve 611 is provided, with a fixed box 62 fixedly installed on its upper surface. A water bladder 612 is fixedly installed on the inner side wall of the fixed box 62, and a squeezing plate 613 is fixedly installed on the side wall of the water bladder 612. A fixing block 614 is fixedly installed on the other inner side wall of the fixed box 62. A squeezing rod 615 is slidably installed on the inner wall of the fixing block 614. One end of the squeezing rod 615 is fixedly connected to the side wall of the squeezing plate 613. A telescopic spring 616 is sleeved on the outer wall of the squeezing rod 615. One end of the telescopic spring 616 is fixedly connected to the side wall of the squeezing plate 613, and the other end of the telescopic spring 616 is fixedly connected to the side wall of the fixing block 614. A water pipe 617 is connected to the water outlet of the water bladder 612. One end of the water pipe 617 extends to the outer surface of the upper surface of the platform 5 and is fixedly installed with a self-tightening nozzle. One end of the top rod 610 is in contact with the side wall of the squeezing plate 613.

[0031] The specific implementation method is as follows: When it is necessary to adjust the height of the worktable on the base 1, the drive motor 2 is started. The drive motor 2 drives the hydraulic rod 3 to move, the hydraulic rod 3 drives the platform 5 to move, and the platform 5 drives the support legs 4 to move on the base 1. After the height of the worktable is adjusted, work begins. When it is necessary to disinfect the worktable surface after work, the handle on the fixed box 62 is used to move the fixed box 62. At this time, the fixed box 62 drives the moving sleeve 66 to move on the travel box 61. At the same time, the moving sleeve 66 drives the rotating rod 65 to move. The rotating rod 65 drives the gear 64 in the travel box 61 to move on the rack 63. Then, the teeth of the rack 63 drive the gear 64 to rotate. At this time, the gear 64 drives the rotating rod 65 to rotate. The rotating rod 65 drives the gear 64 in the moving sleeve 66 to rotate on the rack 63. The reciprocating screw 67 rotates, and the reciprocating screw 67 drives the threaded sleeve 68 to move back and forth through the thread. At the same time, the threaded sleeve 68 drives the moving rod 69 to move back and forth. The moving rod 69 drives the top rod 610 to squeeze the extrusion plate 613 in the fixed boxes 62 on both sides. When the top rod 610 squeezes the extrusion plate 613, the extrusion plate 613 drives the extrusion rod 615 on the fixed block 614 to move synchronously. At the same time, under the support of the fixed block 614, the extrusion plate 613 stretches the telescopic spring 616. The telescopic spring 616 helps to reset the extrusion plate 613. At this time, the extrusion plate 613 squeezes the water bag 612 in the fixed box 62, thereby squeezing the disinfectant in the water bag 612 into the water pipe 617, and then spraying it from the self-tightening nozzle on the water pipe 617 onto the workbench surface for disinfection.

[0032] The cleaning component 7 includes a connecting block 72, the upper surface of which is fixedly connected to the lower surface of the support sleeve 611. A brush plate 71 is fixedly installed on the lower surface of the connecting block 72, and a brush is provided on the lower surface of the brush plate 71, with the brush fitting against the upper surface of the platform 5.

[0033] The specific implementation method is as follows: when the movable sleeve 66 moves, the connecting block 72 drives the brush plate 71 to move, and then the brush of the brush plate 71 cleans the work surface.

[0034] Working principle: When the height of the worktable on the base 1 needs to be adjusted, the drive motor 2 is started. The drive motor 2 drives the hydraulic rod 3 to move, the hydraulic rod 3 drives the platform 5 to move, and the platform 5 drives the support legs 4 to move on the base 1. After the height of the worktable is adjusted, work begins. When the worktable needs to be disinfected after work, the handle on the fixed box 62 is used to move the fixed box 62. At this time, the fixed box 62 drives the moving sleeve 66 to move on the travel box 61. At the same time, the moving sleeve 66 drives the rotating rod 65 to move. The rotating rod 65 drives the gear 64 in the travel box 61 to move on the rack 63. Then, the teeth of the rack 63 drive the gear 64 to rotate. At this time, the gear 64 drives the rotating rod 65 to rotate. The rotating rod 65 drives the reciprocating screw 67 in the moving sleeve 66 to rotate. 7. The threaded sleeve 68 moves back and forth via the threaded thread, and the threaded sleeve 68 moves the moving rod 69 back and forth. The moving rod 69 moves the top rod 610 to press the extrusion plate 613 in the fixed boxes 62 on both sides. When the top rod 610 presses the extrusion plate 613, the extrusion plate 613 moves the extrusion rod 615 on the fixed block 614 in sync. At the same time, under the support of the fixed block 614, the extrusion plate 613 stretches the telescopic spring 616. At this time, the extrusion plate 613 presses the water bladder 612 in the fixed box 62, thereby squeezing the disinfectant in the water bladder 612 into the water pipe 617, and then spraying it from the self-tightening nozzle on the water pipe 617 onto the workbench surface for disinfection. When the moving sleeve 66 moves, the brush plate 71 moves via the connecting block 72, and the brush plate 71 cleans the workbench surface.
