Medial surface be respectively provided with vertical air intake duct, be provided with negative-pressure air fan, the negative-pressure air fan below the square table matrix
Inlet end be provided with the negative-pressure pipeline extended on the outside of side panel and top plate, the negative-pressure pipeline respectively with horizontal air intake duct and
Bronchus is provided between vertical air intake duct to be connected, the gas outlet of the negative-pressure air fan is provided with filter.
Wherein, the backplate is transparency glass plate or acrylic board.
Wherein, the filter is air-purification sterilizing device.
Wherein, it is densely covered with micropore on the horizontal air intake duct and vertical air intake duct.
Wherein, it is provided with garbage recovery device below the square table matrix.
The beneficial effects of the utility model：A kind of smokeless anti-poisoning laboratory table, opens negative-pressure air fan in negative-pressure pipeline
Negative pressure is produced, suction is produced at the micropore on horizontal air intake duct and vertical air intake duct so that between backplate, side panel and top plate
Cavity in produce negative pressure Tiny pore, drive experiment in caused pernicious gas and flue dust enter filter, filter out harmful
Emitted again after gas and flue dust, avoid the injury to human body, improve the security of operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.

Pipe 5, the lower section of square table matrix 1 are provided with negative-pressure air fan 9, and the inlet end of the negative-pressure air fan 9, which is provided with, extends to side panel 2
With the negative-pressure pipeline 8 of 3 sides outside top plate, the negative-pressure pipeline 8 is provided between horizontal air intake duct 4 and vertical air intake duct 5 respectively
Bronchus 7 is connected, and the gas outlet of the negative-pressure air fan is provided with filter 10, opens after negative-pressure air fan 9 in negative-pressure pipeline 8
Middle generation negative pressure, suction is produced at the micropore on horizontal air intake duct 4 and vertical air intake duct 5 so that the micro- gas of negative pressure is produced in cavity
Stream, caused pernicious gas and flue dust in experiment is driven to be filtered into filter 10.
In the present embodiment, the backplate 6 is transparency glass plate or acrylic board, and transparency is high, and daylighting is good, Er Qiefang
Shield property is good.
In the present embodiment, the filter 10 is air-purification sterilizing device, can filter out flue dust in air and
Pernicious gas, bacterium is killed, gives off harmless air.
In the present embodiment, micropore is densely covered with the horizontal air intake duct 4 and vertical air intake duct 5, micropore can both make cavity
Interior gas enters horizontal air intake duct 4 and vertical air intake duct 5, and and can increases the uniformity of air-flow, reduces noise.
In the present embodiment, the lower section of square table matrix 1 is provided with garbage recovery device 11, and rubbish returns in convenient experiment
Receive, reduce environmental pollution.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
To limitation of the present utility model.
