Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one.
Fig. 2 is the structural representation of the embodiment of the invention two.
Fig. 3 is the structural representation of the embodiment of the invention three.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment one:
Referring to Fig. 1, biological particle sampling enrichment system of the present invention comprises master control set and sampling enriching apparatus.Master control set comprises high pressure generator 1, motor 2 and controller 3, and above-mentioned device is placed in the casing 4; The sampling enriching apparatus mainly is made up of pedestal 5, collection cups 6, discharge portion 7 and pneumatic pump 8, and above-mentioned each device is placed in another casing 19.Pedestal 5 is made by conductive material, in have a concave station to be used to place collection cups; The shell 20 of discharge portion 7 is an electrical insulator; Collection cups 6 is placed in the pedestal 5, is contained with in the cup to collect damping fluid 16; Discharge portion 7, pneumatic pump 8 all are connected with pedestal 5, and are assembled together by sealing fasteners such as O RunddichtringO 9, clamping nuts 10.The needle electrode 11 of discharge portion 7 be arranged on collection cups 6 directly over, in the passage 12 of discharge portion 7, be provided with a coarse particle collecting board 14 near air intake 13 places.High pressure generator 1 provides high voltage for needle electrode 11, and motor 2 provides driving power for pneumatic pump 8, controller be mainly used in height, the motor of control voltage rotating speed, pedestal current potential and to the control of complete machine co-ordination etc.
Under the effect of pneumatic pump 8, the air that has virus, bacterium enters from air intake 13, through coarse particle collecting board 14, scribble the material that can stick coarse grained glue class on this plate, these coarse particles are collected on this plate,, are difficult for being sticked by this plate because the diameter of bacterium and virus is less; The air band bacterium at this moment, virus continues to enter discharge cavity 15 along passage 12; 15 li of this discharge cavities, the needle electrode 11 that has high pressure makes air ionization to atmospherical discharges, is that bacterium, virus are charged then; Charged bacterium, virus continue to enter the damping fluid 16 in bacterium, the collection virus cup 6, because the damping fluid surface is electronegative potential or zero potential, so and formed an electric field between the needle electrode 11, at this moment, charged bacterium, virus are in air-flow adds the damping fluid that is sent under the electric field force effect in the collection cups 6.Virus of collecting or bacterium are delivered to the laboratory and detect.The present invention can also collect and be suspended in airborne other biological particulate, as the spore of fungi, mite, fern; Ferment, microbiotic and other products etc. that biotechnology is made.
The sampling enriching apparatus can separate with master control set fully, finishes using and can carry out disinfection respectively, the high temperature of this sampling enriching apparatus 100 ℃ of abilities when sterilizing and can not destroy its performance.
Embodiment two:
Referring to Fig. 2, replace collection cups 6 with collecting board 17, scribble the colloid material 18 that can collect bacterium, virus on its plate; Also can be the other forms of utensil that holds, for example collect rod etc.
Embodiment three:
Referring to Fig. 3, in the present embodiment, pedestal 5 is not made with conductive material, therefore draws a lead-in wire 25 to controller 3 from damping fluid, make between damping fluid and the spray point to form an electric field, help being enriched on the cushion under biological particle adds electric field force along air-flow the effect.
Though the present invention discloses as above with preferred embodiment, is not in order to limit scope of the invention process.Any those of ordinary skill in the art, without departing from the spirit and scope of the present invention, when doing a little change and retouching, promptly all equalizations of being done according to invention change and modify, and should be claim of the present invention and contain.
