[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] An embodiment of the present application discloses a reagent liquid dispensing device, including a dispensing seat 1, a box body 5 fixedly connected to the top of the dispensing seat 1, a telescopic tube 6 fixedly connected to the outlet of the box body 5, a connecting hard tube 7 and a connecting hose 8 fixedly connected to the lower end of the telescopic tube 6 in sequence, the surface of the dispensing seat 1 is connected to the connecting hard tube 7 by setting a lifting mechanism, a connecting plate 9 is fixedly sleeved on the surface of the connecting hard tube 7, a baffle 10 is fixedly sleeved on the surface of the connecting hose 8, a spring 11 is uprightly arranged between the baffle 10 and the connecting plate 9, and the spring 11 is sleeved on the outer surface of the connecting hose 8.

[0019] Furthermore, a positioning groove 2 is provided on the upper surface of the bottom of the liquid dispensing seat 1 . The positioning groove 2 is aligned with the connecting hose 8 , and the positioning groove 2 is used to place a test tube.

[0020] Furthermore, the lifting mechanism includes an electric push rod 4 fixedly installed at the bottom of the box body 5, the telescopic end of the electric push rod 4 is fixedly connected to the lifting plate 3, and the lifting plate 3 is fixedly connected to the connecting hard pipe 7. By driving the electric push rod 4 to extend and retract, the lifting plate 3 is driven to move up and down, thereby driving the connecting hard pipe 7 and the connecting hose 8 to move.

[0021] In this embodiment, when separating liquid, the test tube is first placed inside the positioning groove 2, and then the lifting mechanism is used to drive the connecting hard tube 7 and the connecting soft tube 8 to move downward, so that the connecting soft tube 8 enters the inside of the test tube. When the baffle 10 contacts the test tube mouth, the lifting mechanism is used to continue to drive the connecting hard tube 7 to move downward for a distance, so that the connecting plate 9 and the baffle 10 move relative to each other, and the spring 11 between the connecting plate 9 and the baffle 10 is compressed. Under the reaction force of the spring 11, the baffle 10 is pressed against the test tube mouth and fits tightly with the test tube mouth, thereby preventing liquid from splashing out of the test tube mouth during liquid separation.

[0022] In this embodiment, a corresponding solenoid valve body can be set inside the connecting hard pipe 7, and the solenoid valve body is used to control the on and off of the connecting hard pipe 7. In addition, a corresponding pump can be set at the outlet of the box body 5 and connected to the telescopic tube 6. The pump can provide power for the liquid in the box body 5 to facilitate the packaging of the liquid inside the box body 5. The solenoid valve body and the pump are both existing conventional equipment and will not be repeated here.

[0023] Furthermore, a slide groove 14 is provided on the lower surface of the baffle 10 , and two groups of pressure plates 13 are provided inside the slide groove 14 by setting a moving mechanism. The connecting hose 8 is located between the two groups of pressure plates 13 , and the moving mechanism can make the two groups of pressure plates 13 close to or away from the connecting hose 8 .

[0024] Furthermore, the top of the pressing plate 13 and the sliding groove 14 are both provided with a T-shaped structure, and the top of the pressing plate 13 is fitted inside the sliding groove 14 to form a moving pair therein.

[0025] Furthermore, a telescopic bag 15 is fixedly connected between the two groups of pressure plates 13 , a control bag 12 is fixedly connected between the baffle 10 and the connecting plate 9 , and the control bag 12 is connected to the telescopic bag 15 through a vent pipe 16 .

[0026] In this embodiment, a moving mechanism is provided for use in conjunction with the pressure plate 13. When subpackaging is not performed, the moving mechanism can be used to drive the pressure plate 13 to press the connecting hose 8 to prevent leakage of the connecting hose 8. Specifically, during subpackaging, the lifting mechanism drives the connecting hose 8 into the test tube. When the baffle 10 and the connecting plate 9 approach each other, the control bag 12 between the baffle 10 and the connecting plate 9 is compressed, and the gas in the control bag 12 enters the interior of the telescopic bag 15 through the vent pipe 16. The telescopic bag 15 expands and can drive the two groups of pressure plates 13 to move to both sides. The two groups of pressure plates 13 no longer press the connecting hose 8, so that the liquid can be transported normally. After the subpackaging is completed, the lifting mechanism drives the connecting hose 8 to move out of the test tube, the baffle 10 is separated from the test tube mouth, the compressed spring 11 is extended, the baffle 10 and the connecting plate 9 are restored, and the gas in the telescopic bag 15 can re-enter the interior of the telescopic bag 15 through the vent pipe 16. The telescopic bag 15 is restored, driving the pressure plate 13 to press the connecting hose 8 again to prevent leakage of the connecting hose 8.
