[0025] Preferably, the frame 1 is connected to the supporting foot 7 by a hydraulic cylinder 8 for lifting and lowering.

[0026] In the embodiment, when the overall height of the mobile laminar flow hood needs to be adjusted, the power supply is connected to start the hydraulic cylinder 8, and then the telescopic end of the hydraulic cylinder 8 extends to push the frame 1 and the support rod 2 to rise, thereby completing the overall height adjustment of the mobile laminar flow hood.

[0027] Embodiment 2

[0028] See also Figure 1-5 An operating table 10 is arranged inside the frame 1, a motor 9 is connected to the bottom end of the frame 1, a screw rod 11 is arranged inside the support rod 2, one end of the screw rod 11 is connected to a bearing 12, and a threaded sleeve 13 is threadedly connected to the surface of the screw rod 11.

[0029] Preferably, the two side walls of the operating table 10 are connected to the threaded sleeve 13 , and the operating table 10 forms a threaded motion through the threaded sleeve 13 and the screw rod 11 .

[0030] Preferably, one end of the screw rod 11 is connected to the output shaft of the motor 9 , and the screw rod 11 is rotatably connected to the inside of the support rod 2 via a bearing 12 .

[0031] In the embodiment, when the height of the operating table 10 needs to be adjusted, the power supply is connected to start the motor 9 to allow the output shaft to rotate and drive the screw rod 11 to rotate along the inner ring of the bearing 12 inside the support rod 2. At the same time, the thread sleeve 13 moves along the thread on the surface of the screw rod 11. Then the thread sleeve 13 will drive the operating table 10 connected to the side wall to move, and then the operating table 10 will be raised and lowered in the frame 1, thereby adjusting the height of the operating table 10.

[0032] In summary, the mobile laminar flow hood of the utility model adopts 10 height-adjustable operating tables to meet the different requirements of large and small reagent bottles for sterile operating space. In addition, the overall height of the mobile laminar flow hood can be adjusted, and hydraulic lifting is adopted to cope with the mutual transportation of operating rooms of various sizes, realizing multiple uses of one machine.

[0033] It should be noted that the mobile laminar flow hood is mainly used for aseptic operations in the production or inspection links of the biopharmaceutical industry.

Then, when moving, the adjusting rod 702 is rotated and retracted into the interior of the connecting rod 701, and then moved by the moving wheel 6.

[0034] It should be noted that the working principle of the laminar flow hood is to send the indoor air to the operating area in a uniform horizontal airflow through an efficient air filtration system. This horizontal laminar airflow will remove suspended particles and microorganisms to the outside, ensuring that the air in the working area remains clean. At the same time, the laminar flow hood is equipped with a high-efficiency HEPA (high-efficiency particulate air) or ULPA (ultra-high-efficiency particulate air) filter, which can effectively remove tiny particles and microorganisms, ensuring that the air blown down from the top is sterile and clean.
