[0007] By adopting the above technical solution, the cabinet is equipped with ventilation components, an operating room, and compartments to achieve the basic functions of a fume hood. The ventilation components, together with the air guide components, ensure stable air pressure in the operating port and operating room, and prevent the leakage of harmful gases. The control and drive structure drives the table structure to move up and down, which can adjust the height of the operating table to accommodate different experimental personnel. The angle between the tilting platform and the movable platform can be adjusted to control the tilt of the operating table, which facilitates table cleaning. The overall structure is simple and easy to use.

[0008] Furthermore, the drive structure includes multiple telescopic motors, which are located near the four corners of the movable platform. Multiple dovetail blocks extend from opposite sides of the movable platform. Sliding grooves are provided in the cabinet corresponding to the dovetail blocks, and receiving grooves are provided on the upper surface of the movable platform.

[0009] By adopting the above technical solution, multiple telescopic motors synchronously control the lifting and lowering of the movable platform. The dovetail block cooperates with the sliding groove to ensure that the movable platform remains horizontal when it is lifted and lowered, thereby limiting the movement of the movable platform. The groove can accommodate the components that drive the tilting platform and also avoid structural interference with the tilting platform.

[0010] Furthermore, a support rib is provided below the telescopic motor.

The lifting and lowering of the driver output shaft causes the tilting platform to tilt relative to the movable platform, which facilitates subsequent cleaning operations. The limiting baffles set on both sides of the tilting platform can reduce the seepage of liquid into the cabinet from the side after spillage.

[0016] Furthermore, an end guard is provided on the front side of the top surface of the movable platform. The end guard is L-shaped with the opening facing downward and inward. The height of the end guard is greater than or equal to twice the height of the inclined platform. The end guard includes a fixed guard and a snap-fit ​​baffle that are interlocked with each other. The fixed guard extends vertically on the movable platform, and the snap-fit ​​baffle is L-shaped and snaps with the fixed guard.

[0017] By adopting the above technical solution, the end guards limit and block the tilting platform. When the fume hood is working normally, the tilting platform can be controlled to tilt slightly for easy operation. After the experiment is completed, the tilting degree of the tilting platform can be increased for easy cleaning. After cleaning, the snap-fit ​​baffle can be removed to clean the gaps, ensuring that the work surface is clean and tidy.

[0018] Furthermore, the top of the fixed baffle is provided with a snap-fit ​​groove that snaps into the snap-fit ​​baffle. The snap-fit ​​groove extends with an inlet ramp on the side near the center of the operating chamber. The inner height of the fixed baffle is lower than the outer height.
