It is healthy to have harm.The Chinese utility model patent that Authorization Notice No. is CN204544258U discloses a kind of with board
Bench for chemistry experiment, the bench for chemistry experiment includes reagent rack interlayer, and the reagent rack interlayer downside is provided with can be with the board of push-and-pull.
Its in the structure for not changing original experimental bench, save in experimentation test table top space, it is ensured that laboratory report not by
Corrosion and pollution.But, carried out due to testing on an open experimental bench, noxious material can be produced unavoidably, harm is real
Test the health of personnel.
The content of the invention
In place of in order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of laboratory hood, the ventilation
Cabinet can discharge the toxic gas produced when testing, it is ensured that the personal safety of experimenter.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of laboratory hood, including cabinet,
It is provided with blower fan at the top of the cabinet, the cabinet includes Over-The-Counter and the lower cabinet with work top, the both sides of Over-The-Counter and lower cabinet lead to
Cross in side plate support connection, the Over-The-Counter and be provided with downwardly open upper mozzle, mozzle is connected to blower fan, the work on this
Table top is provided with the air vent being evenly arranged, and the work top bottom surface is connected with the lower mozzle of upward opening, the lower mozzle
Blower fan is connected to by airway tube, the bottom of the airway tube is the transverse tube of horizontality, and another part is upward vertical tube.
In the above-mentioned technical solutions, the work top is provided with tap and tank, the transverse tube and water of the airway tube
Trench bottom is connected, and the vertical tube is connected with transverse tube higher position.
In the above-mentioned technical solutions, the tank is provided with cover plate with transverse tube junction.
In the above-mentioned technical solutions, S-type siphon trap is provided between the transverse tube and tank.
In the above-mentioned technical solutions, illuminating lamp and bactericidal lamp are provided with the Over-The-Counter.
The beneficial effects of the utility model are：By all setting mozzle in the top and bottom of work top, air-breathing from
At gas generation closer to, can will preferably test the toxic gas discharge produced, meanwhile, if workbench overturns chemical drugs because unexpected
When product need to rinse, directly work top can be rinsed, the water after flushing by the direct runner tank of transverse tube, and
During blower fan air-breathing, cover plate is covered or by siphon trap, can prevent lower mozzle gas leakage and weaken getter action.
Brief description of the drawings
