[0015] Preferably, a filter gas box is installed on the top end face of the blower.

[0016] Advantages of the present utility model:

[0017] 1. The baffle can be driven to move through the cylinder and the support rod. Thus, when the equipment is not in use, a sealed space can be formed with the enclosure, preventing bacteria and dust in the air from entering and contaminating the tabletop, ensuring the cleanliness of the tabletop, reducing the cleaning workload. During the sealing period, the tabletop area can be sterilized through the ultraviolet lamp to prevent bacteria from growing on the equipment. The first air outlet frame and the second air outlet frame can operate synchronously through the air duct and the branch pipe, improving the cleanliness of the working area.

[0018] 2. The baffle can be limited by the sliding groove and the sliding block, making the baffle move more stably during movement and preventing phenomena such as detachment and deviation. The height of the tabletop can be adjusted through the lifting column and the controller, which is beneficial for staff of different heights to use, improving the usability of the equipment. The sealing performance between the baffle and the enclosure can be improved through the sealing strip. Description of the Drawings
