[0023] In this application, a slidable curtain 7 that can be opened and closed is provided on the front side of the rectangular frame 5. The rectangular frame 5 can be enclosed to form a relatively enclosed space to form a relatively enclosed operation area. Thus, during operation, the operation area can be prevented from being polluted by the outside world, and the cleanliness of the operation area can be greatly improved.

[0024] In addition, an air outlet nozzle 8 is provided on one side of the surrounding curtain 6. The air outlet nozzle 8 is connected to an air outlet pipe 9. The top of the air outlet pipe 9 extends to one side of the air inlet 2 of the top cover 1 of the laminar flow hood. Thus, an air flow cycle can be formed. The gas in the operation area flows out from the air outlet cylinder 11, then flows to the air inlet 2, enters the top cover 1 of the laminar flow hood, is purified by various components in the top cover 1 of the laminar flow hood, and then flows back into the operation area, facilitating the downward flow of the gas flowing out from the air outlet 3 of the top cover 1 of the laminar flow hood. Thus, the uniformity of the air volume in the rectangular frame 5 is improved, and the purification effect is enhanced.

[0025] In addition, an operation board 10 is detachably connected to the bottom of the rectangular frame 5. Specifically, support bars are provided on the rectangular frame 5, and the operation board 10 is placed on the support bars. An elevating operation table 12 is provided above the operation board 10 through an electric push rod 14. Thus, the height of the operation table 12 can be adjusted relatively according to the actual operation situation, and the adjustment is more flexible and reliable. The setting of the operation board 10 can, on the one hand, enclose the operation area to a certain extent at the bottom, and on the other hand, operation items can be placed on the operation board 10. The detachable connection of the operation board 10 enables the operation board 10 to be detached according to the actual application situation, facilitating the use of the laminar flow hood.

[0026] In addition, an air outlet cylinder 11 is provided on each of the left and right sides inside the rectangular frame 5. The bottom of the air outlet cylinder 11 faces the inside of the rectangular frame 5, and the other end faces the air outlet 3. Through this setting, it is convenient to divide the air flow flowing out from the air outlet 3, and it is convenient for some clean gas coming out from the air outlet 3 to be guided from the air outlet cylinder 11 to the middle inside of the rectangular frame 5, that is, air flows into the top and the middle parts of the left and right sides of the rectangular frame 5, improving the air flow uniformity and the cleanliness effect.

[0027] In addition, a disinfection lamp 13 is provided at the bottom of the laminar flow hood. Thus, according to the specific operation situation, the disinfection lamp 13 can be turned on to disinfect the operation area inside the rectangular frame 5 to further improve the cleanliness of the operation area.
