Description
Technical Field
The utility model relates to a liquid is stored and is carried the apparatus field, especially relates to a vapour-pressure type liquid storage transport structure.
Background
In chemical and biochemical tests, the situation that a reaction is performed for half and a reagent (particularly a liquid reagent) needs to be added into a reaction vessel is often faced, the reagent is added into the reaction vessel by using a rubber-head dropper or a pipette in the conventional method for adding the reagent, and the problem exists that an experimenter needs to stand near the reaction vessel in the adding process and the reaction liquid in the reaction vessel splashes to the experimenter due to carelessness.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to the above-mentioned problem, a vapour-pressure type liquid storage transport structure is proposed.
The utility model adopts the following technical scheme:
the utility model provides a vapour-pressure type liquid storage transport structure, includes liquid storage barrel, plug, gas needle and drain pipe, the plug becomes sealed cavity together with liquid storage barrel detachably cooperation, the gas needle peg graft in on the plug, the drain pipe directly or indirectly through the export on the liquid storage barrel with cavity UNICOM.
The device has the following effects that firstly, the liquid storage cylinder is filled with liquid (namely reagent), then the rubber plug is tightly covered (a cavity formed between the liquid storage cylinder and the rubber plug is used for storing the liquid), the air needle is inserted, one end of the liquid outlet pipe is directly or indirectly communicated with the reaction vessel, when the air needle does not inflate the liquid storage cylinder, the liquid in the liquid storage cylinder cannot leave the liquid storage cylinder and enter the liquid outlet pipe, when the air needle inflates the liquid storage cylinder, the liquid in the liquid storage cylinder is pressed into the liquid outlet pipe under the pressure of gas, and then enters the reaction vessel.
This structure is through gaseous pressure with liquid extrusion in the reaction household utensils, need not the tester and stands near the operation of reaction household utensils, the operation is more convenient, factor of safety is high.
Optionally, the liquid outlet pipe is a soft elastic liquid outlet pipe, and the liquid outlet pipe is sleeved on the outer cylinder wall of the liquid storage cylinder.
Optionally, the outlet is formed in the side wall of the liquid storage cylinder, and the wall of the liquid outlet pipe is attached to and plugs the outlet.
Because the pipe wall of drain pipe pastes tightly and plugs up the export on the liquid storage barrel, so can be through the play liquid volume of the gas volume of control gas needle accurate control liquid, because above-mentioned structure only backs up the export by the pressure of liquid self, and the pressure of liquid self can be controlled through controlling the air input.
Optionally, part or all of the outer cylinder wall of the liquid storage cylinder is cylindrical, an annular protrusion is arranged on the cylindrical outer cylinder wall of the liquid storage cylinder, and the outer pipe wall of the liquid outlet pipe is tightly attached to the annular protrusion.
The outer cylinder wall of the liquid storage cylinder is provided with an annular bulge, and the pipe wall of the liquid outlet pipe is tightly attached to the annular bulge, so that liquid cannot overflow from a gap between the liquid storage cylinder and the liquid outlet pipe when leaving from the outlet of the liquid storage cylinder.
Optionally, the liquid outlet pipe is a silicone tube or a rubber tube.
Optionally, the rubber plug is made of latex.
In the same way, in order to accurately control the air inflow of the air needle to the cavity, an air storage tank and a barometer can be connected to the air needle.
The utility model has the advantages that: this structure is through gaseous pressure with liquid extrusion in the reaction household utensils, need not the tester and stands near the operation of reaction household utensils, the operation is more convenient, factor of safety is high.
