Abstract

The invention discloses a laser positioning type liquid transferring gun. The laser positioning type liquid transferring gun comprises a main gun body, wherein a directional air conveying device is arranged on the main gun body and communicated with the inside of the main gun body; the main gun body comprises a gun body; a handle part of the gun body is provided with a liquid absorbing button and a liquid discharging button which are electrically connected to the directional air conveying device; a control table is also arranged on the gun body; a groove is formed in the tail end of the gun body of the main gun body, is connected to a liquid transferring tube and is parallel to the handle; the groove is communicated with the directional air conveying device; the inner top of the groove is provided with a laser transmitter and a laser sensor which are electrically connected to the control table. The laser positioning type liquid transferring gun is novel in structure, small in size and light in weight, can be held in the hand, is convenient and practical and is capable of relieving fatigue caused due to long-term experiment and tension caused due to intensive concentration.

Description

[0001] technical field [0002] The invention relates to a pipetting gun used for biological experiments and chemical experiments, in particular to a laser positioning type pipetting gun. Background technique [0003] At present, pipetting devices are needed in chemical experiments and biological experiments. The more common ones are droppers and electric pipettes. The dropper uses the rubber ball on the upper part to generate thrust when squeezed, and the principle of suction is generated by letting go after squeezing. Realize pipetting; the structure of the electric pipette gun is complex, mainly through the air compressor inside to provide positive pressure to the positive pressure pump, negative pressure to store pressure, release positive pressure or negative pressure during work to achieve suction and push liquid, Achieve pipetting. [0004] During long-term experiments, finger fatigue will occur when using a dropper. However, the electric pipettes currently on the ma...
