In scientific research, it provides a pure, interference-free space for precise experimental operations, ensuring the accuracy and reliability of experimental results. Whether it is reagent processing in chemical experiments or cell culture in biological experiments, the clean bench can effectively prevent the intrusion of external impurities, safeguarding the smooth progress of scientific research. The air intake plate, as an important component of the clean bench, is like the clean bench's "breathing channel." The rationality of its installation structure is not only related to the stability and reliability of the air intake plate itself, but also directly affects the overall performance and service life of the clean bench.

[0003] Chinese utility model patent publication number: CN 211937014 U, discloses: a clean bench, the clean bench, the cover plate setting prevents non-staff from accidentally touching the control panel. By setting an infrared emission device, an infrared detection device, a control device, a human body detection device, and a prompting device, the staff can be prompted to cover the control panel with the cover plate when a person leaves to prevent the control panel from being accidentally touched and operated by non-staff. However, the clean bench is not designed with an air intake plate mounting structure and needs to be installed with bolts, resulting in large installation limitations and inconvenience for subsequent rapid replacement. Secondly, it is not convenient to replace a single area of ​​the air intake plate, resulting in the need to replace the entire air intake plate during replacement, which is inconvenient to install or replace according to actual usage and has poor practicality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an air intake plate mounting structure for a clean workbench, which can effectively solve the problem in the prior art that no air intake plate mounting structure is designed and bolts need to be used for installation, resulting in large installation limitations and inconvenience for subsequent rapid replacement. Secondly, it is not convenient to replace a single area of ​​the air intake plate, resulting in the need to replace the entire air intake plate during replacement, which makes it inconvenient to install or replace according to actual usage conditions and has poor practicality.

[0005] The technical solution adopted by the present utility model is: an air intake plate mounting structure for an ultra-clean workbench, comprising a workbench, and a support frame fixedly mounted on the top of the workbench, an air intake frame fixedly mounted on the other end of the support frame away from the workbench, two card slots 1 are provided on the left and right sides of the inner side of the air intake frame, a limiting component is arranged inside the card slot 1, a mounting frame is provided on the inner side of the other end of the air intake frame away from the support frame, a reinforcing rod is fixedly mounted on the mounting frame close to the other end away from the air intake frame, an air intake plate body is provided on the inner side of the other end of the air intake frame away from the support frame, an air intake groove is provided on the outer surface of the air intake plate body, and a limiting column is fixedly mounted on the center line of the reinforcing rod away from the other end of the workbench.
