AI Technical Summary
Existing laboratory fume hoods require the door to be closed when exhausting waste gas, making it impossible to observe the experimental process and allowing some harmful gases to escape, resulting in incomplete treatment.
An integrated laboratory fume hood was designed, which uses a circular operating table and side hoods to form a closed experimental space. Combined with an exhaust fan and suction hood, it achieves negative pressure adsorption, effectively extracting harmful gases within the closed space, and allowing the experimental process to be observed through transparent glass.
This method allows for the complete removal of harmful gases while observing the experimental process, preventing gas escape and improving experimental safety and data accuracy.
