It can be understood that the driving handle 21 can move up and down under the action of external force, so that the lifting shaft 22 can be synchronously driven to move up and down, and further the liquid level in the liquid storage vessel 10 can be driven to rise or fall.

And it can be understood that, the lifting plate 23 is arranged below the liquid medicine of the liquid storage vessel 10, so that the medicine can move upwards synchronously only when the lifting plate 23 is lifted, even if the liquid level of the medicine is lifted and naturally flows out of the liquid outlet nozzle 11.

Implement the embodiment of the utility model provides a, will have following beneficial effect: when the biochemical reagent storing and taking container is used for taking liquid chemicals, a tester can press the driving handle 21 downwards with slight force, and the driving handle 21 can drive the lifting shaft 22 to slide upwards under the guiding action of the hole wall of the assembling hole 12; because the lifting shaft 22 and the lifting disc 23 are connected into a whole, the lifting disc 23 is lifted upwards synchronously, so that the lifting disc 23 can lift the liquid level of the liquid chemical contained in the liquid storage vessel 10 to a higher height; when the medicine liquid level promoted to liquid outlet 11's height, just can flow out naturally in liquid outlet 11 through gravity, the liquid chemical that the demand flow just can be got to the experimenter. After the medicine is taken, the driving handle 21 is only needed to be loosened, the lifting shaft 22 and the lifting disc 23 automatically fall under the action of gravity, the liquid level in the liquid storage vessel 10 automatically falls, and the medicine cannot continuously flow out of the liquid outlet nozzle 11. Compared with the traditional liquid taking operation mode, the tester does not need to pull a glass bottle with heavy weight and only needs to press the driving handle 21 with slight force, so that the labor intensity is low, and the working efficiency can be greatly improved; in addition, the medicine can not flow to the outer wall of the liquid storage vessel 10, so that hands of the tester can not contact the medicine, and the safety accident of corrosion injury can not occur.

Of course, as an alternative embodiment, when the biochemical reagent storing and taking container is used, the liquid can be obtained by pressing and discharging, that is, the liquid in the liquid storing container 10 is located in the space below the lifting disc 23, the lifting shaft 22 is driven to move downwards by operating the driving handle 21, and the lifting disc 23 is synchronously driven to press downwards, so that pressure is generated to extrude and discharge the liquid from the liquid outlet nozzle 11. The technical effect can be achieved by the scheme. Alternatively, in other embodiments, the biochemical reagent storing and taking container may also adopt other technical means in the prior art to achieve the purpose of discharging the liquid from the liquid storage vessel 10, and will not be described herein again.

In addition, the biochemical reagent access container also comprises a plug 40, and the plug 40 is detachably inserted into the liquid outlet nozzle 11. Therefore, when chemicals do not need to be taken, the liquid outlet nozzle 11 can be blocked, and the safety of the liquid storage vessel 10 is improved.

In the above scheme, when chemicals need to be taken, a tester needs to manually pull off the plug 40; after the taking is finished, a tester is required to manually insert the plug 40, the operation is over-dependent on the tester, and certain inconvenience exists. Based on this, in a further embodiment, biochemical reagent access container still includes connecting piece, first magnetism and second magnetism and inhales the body, the both ends of connecting piece are connected respectively the jam 40 with the outer wall of liquid outlet nozzle 11, first magnetism inhale the body set up in on the liquid outlet nozzle 11, the second magnetism inhale the body set up in on the jam 40, first magnetism inhale the body can with the magnetism of second magnetism is inhaled the body and is connected. Therefore, after chemicals are taken and used, the first magnetic attraction body and the second magnetic attraction body can be automatically separated due to the impact of the chemicals, the plug 40 is separated from the liquid outlet nozzle 11 at the moment, and the chemicals naturally flow out of the liquid outlet nozzle 11; after taking the chemicals, the liquid level of the chemicals inside the device falls synchronously along with the lifting disc 23, so that no chemicals continuously flow out of the liquid outlet nozzle 11, and the first magnetic attraction body can be automatically attracted with the second magnetic attraction body again through the magnetic attraction force without being impacted by the chemicals, namely the liquid outlet nozzle 11 is blocked by the blocking plug 40. The whole process does not need the participation of testers, the labor intensity can be further reduced, and the working efficiency is improved.

Therefore, the contact sealing performance between the lifting disc 23 and the inner wall of the liquid storage vessel 10 can be enhanced, and the chemicals are prevented from leaking to the lower part of the lifting disc 23. It can be understood that the disc body is a circular plate body with a complete surface, and the flexible sealing element is a rubber ring; the rubber ring is sleeved and fixed on the periphery of the circular plate body, and the outer ring wall of the rubber ring is in close contact with the inner wall of the liquid storage vessel 10. Therefore, after the lifting disc 23 moves upwards for a certain distance, the internal cavity of the liquid storage vessel 10 can be divided into an upper cavity and a lower cavity which are not communicated with each other, and at the moment, the liquid in the liquid storage vessel 10 is positioned in the upper cavity and cannot leak into the lower cavity; the liquid follows the lifting disc 23 and moves upwards until it exits from the spout 11.

The funnel-shaped design is adopted, so that the newly added chemicals slowly flow into the liquid storage vessel 10, and the potential safety hazard caused by the over-high flow speed is avoided.

In addition, a filter screen is further installed on the liquid inlet channel of the liquid inlet nozzle 13 to filter out impurities in the newly added chemical, so that influence and interference on the accuracy of a subsequent test result are avoided.

Further, in order to avoid adding liquid into the liquid storage vessel 10, the liquid is prevented from splashing, a drainage device can be arranged at the liquid inlet nozzle 13 to guide the liquid, so that the problems are prevented. It will be appreciated that the drainage device may be, but is not limited to, a funnel, a pour tube, etc.
