Laboratory integrated experiment ventilation cabinet

Abstract

The invention discloses a laboratory integrated experiment ventilation cabinet. The laboratory integrated experiment ventilation cabinet comprises a circulating air supplementing ventilation cabinet,a negative pressure experiment operation cavity is formed in the circulating air supplementing ventilation cabinet, and a water nozzle and a socket are arranged in the negative pressure experiment operation cavity. A flow guiding air way is arranged on the back side of the circulating air supplementing ventilation cabinet, air outlets are formed in the flow guiding air way, and an air outflow boxis arranged on the upper side of the circulating air supplementing ventilation cabinet to communicate with the flow guiding air way. The laboratory integrated experiment ventilation cabinet further comprises a ventilation integrated connector, and the ventilation integrated connector communicates with an air inflow box and the air outflow box through an air inflow pipe and an air outflow pipe. Thelaboratory integrated experiment ventilation cabinet further comprises an external integrated connector. Through the cooperation of optimization and improvement of the ventilation cabinet air way andthe design of the ventilation integrated connector, ventilation connection integration of the ventilation cabinet is achieved, water supply and power supply connection integration of the ventilationcabinet is achieved through the external integrated connector, once the ventilation cabinet needs to be moved and modified, it is not needed to be connected with an air pipe, a water pipe, an electricwire or else, and the safety is improved while the efficiency is improved.

Description

technical field [0001] The invention relates to the field of laboratory technology, in particular to an integrated experimental fume hood applied to laboratory work. Background technique [0002] During the experimental operation of the experimental instrument bench, when corrosive liquids are used, or toxic and harmful gases may be generated during the experiment, reliable fume hoods are needed to ensure the health and safety of the experimenters, and at the same time provide the experimenters with A stable environment is also crucial to the accuracy of experimental data. However, the air in the laboratory must be exchanged with the outside air, and there are higher requirements for the connection of ventilation ducts. At the same time, to ensure the normal progress of the experiment, the instrument also needs to be connected with supporting water and electricity devices, which has great restrictions on the fume hood, especially when it needs to be moved or changed, the re...

However, the air in the laboratory must be exchanged with the outside air, and there are higher requirements for the connection of ventilation pipes.

At the same time, to ensure the normal progress of the experiment, the instrument also needs to be connected with supporting water and electricity devices, which has great restrictions on the fume hood, especially when it needs to be moved or changed, the rearrangement of ventilation, water, and electricity is a big problem
