Flow deflector is connected with the first push rod on one side far from the second flow deflector, and the first push rod extends to cylindrical outer tube by cylindrical drum opening
Portion, the second flow deflector are connected with the second push rod on one side far from the first flow deflector, and the second push rod passes through the other end of cylindrical drum to extend
To cylindrical outer tube, pipette is connected to outside the cylindrical drum other end；First flow deflector angularly offers multiple first ducts, and second
Multiple second ducts are angularly offered on flow deflector.
The utility model is also characterized by：
The outer wall of cylindrical drum is provided with graduation mark.
First flow deflector, the second flow deflector outer eaves be socketed with soft gel coat, each soft gel coat is affixed with cylindrical drum inner wall
It closes.

Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of liquid relief of the utility model and dropping liquid integral type experimental provision, as shown in Figure 1, including one end open, transparent
Cylindrical drum 1, cylindrical drum 1 are inwardly connected separately with the first flow deflector 2, the second flow deflector 3, the first flow deflector by open end along inner wall
2 are connected with the first push rod 4 on one side far from the second flow deflector 3, and the first push rod 4 is extended to by 1 opening of cylindrical drum outside cylindrical drum 1
Portion, the second flow deflector 3 are connected with the second push rod 5 on one side far from the first flow deflector 2, and the second push rod 5 passes through the other end of cylindrical drum 1
It extends to outside cylindrical drum 1, pipette 9 is communicated with outside 1 other end of cylindrical drum；First flow deflector 2 angularly offers multiple
One duct 6 angularly offers multiple second ducts 8 on second flow deflector 3.
The outer wall of cylindrical drum 1 is provided with graduation mark 7, can quantify and measure liquid.
First flow deflector 2, the second flow deflector 3 outer eaves be socketed with soft gel coat 11, each soft gel coat 11 in cylindrical drum 1
Wall fits, and makes the first flow deflector 2, the second flow deflector 3 and the leakproofness of cylindrical drum 1 preferable in use.
Second push rod 5 is connected with plug 10 in 1 outer one end of cylindrical drum, is convenient for the promotion of the second push rod 5, additionally it is possible to prevent the
Two push rods 5 enter in cylindrical drum 1.
First duct 6, the second duct 8 at least there are three, dropping liquid constantly be convenient for control liquid droping speed.
A kind of liquid relief of the utility model and the application method of dropping liquid integral type experimental provision are as follows：
In use, pushing the first push rod 4, the first flow deflector 2, the second flow deflector 3 will be made to be pushed into cylindrical drum 1 close to pipette
9 one end；The first push rod 4 is rotated, the first push rod 4 drives the first flow deflector 2, makes the first duct 6 on the first flow deflector 2 simultaneously
It is staggered completely with the second duct 8 on the second flow deflector 3；Pipette 9 is stretched in liquid to be added dropwise, by the second push rod 5
It is pushed to 1 open end of cylindrical drum, then in liquid sucking cylindrical drum 1, while the dropping liquid that needs measure is judged by graduation mark 7
Amount；Experimental provision is moved to the experiment container mouth for needing to be added dropwise, rotates the first push rod 4, adjusts the first duct 6 and the second duct 8
Overlapping area realizes that liquid constant speed is added dropwise with this.
A kind of liquid relief of the utility model and another application method of dropping liquid integral type experimental provision are as follows：
The first push rod 4 is pushed, the first flow deflector 2, the second flow deflector 3 will be made to be pushed into cylindrical drum 1 close to the one of pipette 9
End；Rotate the first push rod 4, the first push rod 4 drives the first flow deflector 2 simultaneously, makes the first duct 6 on the first flow deflector 2 and the
The second duct 8 on two flow deflectors 3 is staggered completely；Pipette 9 is stretched in liquid to be transferred, by the second push rod 5 to circle
1 open end of column casing pushes, then in liquid sucking cylindrical drum 1, while the amount for the dropping liquid for judging to need to measure by graduation mark 7；
Experimental provision is moved to the experiment container mouth for needing to add solution, pushes the first push rod 4 to cylindrical drum 1 close to 9 one end of pipette,
The quantitative transfer to liquid is realized with this.
By the above-mentioned means, a kind of liquid relief of the utility model and dropping liquid integral type experimental provision, can realize to liquid
Quantitative transfer, constant speed are added dropwise；Also have the advantages that simple in structure, good airproof performance, easy to operate, accuracy, flexibility are good.
