Abstract
The utility model discloses an improved micro-quantitative suction pipe. The improved micro-quantitative suction pipe comprises a quantitative straight pipe, a solution cavity and a buffering cavity communicated with the solution cavity. A solution suction opening is formed in one end of the quantitative straight pipe, and the other end of the quantitative straight pipe is communicated with the solution cavity. The improved micro-quantitative suction pipe is ingenious in design. The buffering cavity and the solution cavity are adopted, negative pressure sucks liquid, and excessive suction does not occur. A communicating pipe is arranged to guarantee quantification accuracy. Due to the fact that an angle is formed between the communicating pipe and the quantitative straight pipe, errors are avoided, the liquid can enter and exit from the solution cavity smoothly, and quantitative sucking and moving of the liquid of large batches or small batches are easy.

The suction pipe that this technical scheme provides is by extruding cushion chamber, and for negative pressure is provided in suction pipe, quantitative liquid suction is to fluid chamber, without watching graduation mark attentively, convenient, fast, and this suction pipe of different model provides not isometric quantitative straight tube.
As preferably, described fluid chamber is divided into Connectivity Section, interlude and latter end successively from top to bottom, and the top of described Connectivity Section is provided with interconnecting part, and a side of described interconnecting part is provided with the first opening, and the opposite side of described interconnecting part is provided with the second opening.
As preferably, a side on described quantitative straight tube top is provided with the 3rd opening, between described the first opening and described the 3rd opening by being communicated with described quantitative straight tube and described fluid chamber communicating pipe.
Guarantee can not enter fluid chamber when liquid is filled quantitative straight tube, avoided the appearance of error, guarantee the quantitative degree of accuracy.
As preferably, the most significant end of described quantitative straight tube, higher than the most significant end of described fluid chamber, is 30-60 ° of angle between described communicating pipe and described quantitative straight tube.
Communicating pipe arranges at an angle with quantitative straight tube, and when imbibition, first liquid is not easy to enter fluid chamber when filling quantitative straight tube, has avoided error.And after filling, unclamping cushion chamber, liquid has and can enter smoothly fluid chamber along the communicating pipe of downward direction.
As preferably, described quantitative straight tube and described fluid chamber be arranged in parallel.Operate conveniently, smoothly, also reduced the difficulty of technique while producing.
As preferably, bottom one side of described cushion chamber has the 4th opening, between described the second opening and described the 4th opening, by separator tube, is communicated with described fluid chamber and described cushion chamber.
Arrange and arrange relative communicating pipe of separator tube and phase port, avoided suction; In use, also facilitate extruding of liquid.
As preferably, described cushion chamber be located at described fluid chamber directly over, handled easily, has reduced the difficulty of production technology, reduces costs.
As preferably, between described separator tube and described fluid chamber and before described fluid chamber and described quantitative straight tube, be provided with compacting portion, for whole suction pipe provides a rigid support, strengthen the intensity of suction pipe, also facilitate hand-held suction pipe operation simultaneously; During production technology, difficulty reduces.
As preferably, described fluid chamber is greater than described cushion chamber.
This technical scheme can guarantee that the negative pressure producing is enough to liquid to suck, and can not be communicated with the mouth of pipe because negative pressure is plugged not.
As preferably, described fluid chamber and the equal ovalize of described cushion chamber, cushion chamber facilitates hand to take operation, and oval is a round and smooth fluid chamber of liquid carrying confession, when the extruding of liquid, avoids the residual of turning.
By implementing technique scheme, the utlity model has following beneficial effect: the utility model ingehious design, adopt cushion chamber and fluid chamber, vacuum suction liquid, there will not be again suction; Arranging of communicating pipe can guarantee the quantitative degree of accuracy; Communicating pipe and quantitatively the angle setting between straight tube, avoided error, also guarantees that liquid can pass in and out fluid chamber smoothly simultaneously, is applicable to quantitative absorption and the movement of big or small bulk liquid.
