Description
Technical field
Laboratory apparatus is the utility model is related to, more particularly, to a kind of counter liquid-transfering gun.
Background technology
Liquid-transfering gun is one kind of pipettor, is usually used in that laboratory is a small amount of or micro liquid pipettes, specification is different, difference rule
The liquid-transfering gun of lattice supports the use different size of pipette tips, and the shape of different manufacturer's productions is also slightly different, but operation principle
And operating method is basically identical.In experimentation, some experiments, which need to be spaced, repeatedly adds reagent or solution processing, and also one
A little experimental amounts are big（Such as sample detection）Need to add reagent or solution one by one, experimenter be interrupted after it is easy to forget that（Or by mistake
Note）Number has been loaded, has directly affected the accuracy of experimental result, has caused the failure of an experiment, and then has extended experimental period, has been wasted raw material
（The especially reagent of price costly）.
The content of the invention
The utility model purpose is to provide a kind of counter liquid-transfering gun with tally function.
To achieve the above object, the utility model takes following technical proposals：
Counter liquid-transfering gun described in the utility model, including gun body, the gun body include housing, are arranged on the housing
Interior piston component and pusher, the piston component include the piston rod that top is fixed with promoting button, the piston rod
Bottom is provided with convex platform, is provided with lower convex platform in the housing below the convex platform, and piston rod bottom is through under described
Boss is connected with the pusher, and back-moving spring is provided with the piston rod between the upper and lower boss, and described
It is provided with counting device in the housing of back-moving spring corresponding position, power supply that the counting device includes being arranged in housing,
With the counting chip and pressure sensor of the power electric connection, the pressure sensor is arranged on the shell of the lower convex platform side
On body；Hull outside is provided with display screen and zero button；The pressure sensor, the button that is zeroed signal output part and institute
State the signal input part electrical connection of counting chip, the signal input part of the signal output part of the counting chip and the display screen
Electrical connection.
The pressure sensor is electrostatic capacity type pressure sensor.
The utility model advantage is simple in construction, can realize accurate counting, reduce experimental error.During work, pass through
Pressing promoting button drives piston rod to move down, when back-moving spring is completely in compressive state, the convex platform on piston rod
Pressure sensor is touched, pressure sensor transmits signals to counting chip and shown through display screen；Convex platform and pressure sensing
Device is often touched once, and the numeral on display screen adds " 1 ", after experiment terminates, can be returned the numeral on display screen by the button that is zeroed
Zero, it is easy to next use, accurate measure pipettes number in experimentation, effectively avoids testing caused by operator forgets
Error.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
Embodiment
As illustrated, counter liquid-transfering gun described in the utility model, including gun body, the gun body include housing 1, set
Piston component and pusher 2 in the housing 1, the piston component include the piston that top is fixed with promoting button 3
Bar 4, the bottom of piston rod 4 are provided with convex platform 5, and lower convex platform 6 is fixed with the housing 1 of the lower section of convex platform 5, living
The bottom of stopper rod 4 is connected through the lower convex platform 6 with the pusher 2, the piston between the upper and lower boss 5,6
Back-moving spring 7 is provided with bar 4（Back-moving spring 7 is compression spring）, in the housing 1 of the corresponding position of back-moving spring 7
Counting device is provided with, the counting device includes the power supply 8 being arranged in housing 1, the counting core electrically connected with the power supply 8
Piece 9 and pressure sensor 10（For for electrostatic capacity type pressure sensor）, the pressure sensor 10 is arranged on the lower convex platform 6
On the housing 1 of side；The outside spacers of housing 1 are provided with display screen 11 and zero button 12；The pressure sensor 10, zero are pressed
Signal input part of the signal output part of button 12 with the counting chip 9 electrically connects, the signal output part of the counting chip 9
Electrically connected with the signal input part of the display screen 11.
During actual installation, power supply 8 is button cell（It is of course also possible to it is common batteries or battery）, in the outside of housing 1
It is provided with the switch of control power supply 8；Above-mentioned electric elements counting chip 9, display screen 11, the electricity of 10 uniform power of pressure sensor 8
Connection.
During work, turn on the power, the numeral on display screen 11 be zeroed, pipetting can be carried out after adjusting liquid relief amount,
During liquid relief, press down on promoting button 3 and the imbibition of pusher 2 is extruded by piston rod 4, when piston rod 4 compresses back-moving spring 7
During in most short status, convex platform 5 touches pressure sensor 10, and signal is passed to counting chip 9 and passed through by pressure sensor 10
Display screen 11 shows that convex platform 5 is often touched once with pressure sensor 10, and the numeral on display screen 11 adds " 1 ", is testing
During, it is necessary to first draw reagent out of reagent bottle with gun body, then add reagent on again to reaction bulb, therefore often complete once
Sample-adding operation, convex platform 5 are touched twice with pressure sensor 10, and the numeral on display screen 11 adds " 2 ", that is to say, that has been loaded
Cheng Hou, the numeral on display screen 11 are be loaded number 2 times.The utility model when in use, passes through what is shown on display screen 11
Numeral, sample-adding number is able to record, and then effectively reduces the probability for causing the failure of an experiment because of operator's forgetting or misdescription.
