But existing micropipettor is due to non-industrial mass production, pipettor to pipette precision not accurate enough, In food inspection, the volume of sampling not enough can accurately cause experimental configuration to there is certain deviation, there is certain food safety Hidden danger, is unfavorable for that people's is healthy.
The content of the invention
It is an object of the invention to provide a kind of micropipettor of food inspection, to solve to carry in above-mentioned background technology The problem for going out.
For achieving the above object, the present invention provides following technical scheme:
A kind of micropipettor of food inspection, including pipettor body;The pipettor body is mainly by socket, pushes away Handss, connecting rod and suction nozzle are constituted, and the socket bottom is fixedly connected with connecting tube, and connecting tube is connected with socket, the liquid relief Device bodies top is provided with pushing hands, and pipettor is originally provided with connecting rod in vivo, and connecting rod is fixedly connected with pushing hands, and connecting rod is prolonged Extend inside socket;The connecting rod bottom is fixedly connected with piston;Spring, the pipettor is provided with the socket socket Body bottom portion is removably connected with suction nozzle, and suction nozzle is hollow structure, and suction nozzle inner top is fixedly connected with dividing plate, uniform cloth on dividing plate It is provided with multiple micropores;The suction nozzle is internally located in dividing plate upper inner wall and is fixedly connected with obstruction lobe, and obstruction lobe is semiglobe And obstruction lobe is integrally formed with suction nozzle;Ball float is provided between the obstruction lobe and dividing plate.
As further scheme of the invention:The pipettor body is made using rigid plastics material, pipettor body Socket is provided with, socket is hollow structure.
As further scheme of the invention:The piston is fixedly connected on connecting rod bottom by way of hot pressing.
As further scheme of the invention:The both ends of the spring has been respectively fixedly connected with piston lower surface and socket Bottom interior wall.
As further scheme of the invention:The ball float with diameter greater than obstruction the distance between lobe.
Compared with prior art, the invention has the beneficial effects as follows:The micropipettor effectively can precisely pipette quantitative treating Determine solution, it is to avoid solution to refer to when pipetting that excessively cause testing result inaccurate, and the solution that the device pipettes is quantitative, detection As a result accurately, substantially increase food consumption safety.
