Abstract

The invention discloses a novel fume hood. The fume hood comprises a body, wherein the body is provided with an electric air valve; a lifting safety sliding door is arranged on the front of the body; and a face velocity sensor is also arranged on the front of the body. The fume hood also comprises a central control system electrically connected with the electric air valve, the safety sliding door and the face velocity sensor, wherein the face velocity sensor monitors pressure changes in the body after the safety sliding door is lifted, converts the values of pressure changes in the body into electrical signals and transmits the electrical signals to the central control system; and the opening angle of the electric air valve and lifting of the safety sliding door are controlled by the central control system. The fume hood has the following beneficial effects that: energy consumption and air loss in the laboratory are greatly reduced so that a relatively stable environment is maintained for experiments, thus achieving the aims of energy conservation and environmental protection and greatly improving the comfort level and environmental protection property of the laboratory.

Description

technical field

[0001] The invention relates to a novel fume hood. Background technique

[0002] Fume hood is a kind of ventilation equipment widely used at home and abroad. The fume hood has complete functions and tight protection, which not only provides comprehensive protection for operators, but also can withstand the corrosion of various chemical acids and alkalis and organic reagents, and does not contaminate the experimental samples inside. It ensures the smooth discharge of toxic, harmful, and odorous gases, making the experimental environment meet the safety requirements stipulated by national regulations. However, traditional fume hoods use forced ventilation to discharge toxic gases outside, causing serious loss of indoor air and temperature. The imbalance of air pressure brings inconvenience to the experimenters and even hidden dangers in the experiment. Contents of the invention

[0003] The object of the invention aims to provide a kind of novel fume hood, ...
