Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purposes and the effects of the present utility model easy to understand, the following embodiments specifically describe the technical scheme of the present utility model with reference to the accompanying drawings.
Referring to fig. 1 and 2, a liquid inlet 1 is provided below the liquid taking device 100; an air guide port 2 is arranged above the liquid taking device 100; a first liquid storage part 3 is arranged at a position close to the liquid inlet 1 and is used for storing the entered liquid reagent; a second liquid storage part 4 is arranged at a position close to the air guide port 2 and used for storing part of liquid reagent, and the second liquid storage part 4 is positioned above the first liquid storage part 3; the side wall of the second liquid storage part 4 is provided with scale marks 5 for marking the current scale capacity, and specifically, the liquid taking device 100 is made of transparent glass.
Alternatively, referring to fig. 4, a standard scale mark 6 is provided on the side wall of the second liquid storage portion 4, and the standard scale mark 6 marks the standard capacity of the liquid dispenser 100, specifically, when the liquid dispenser 100 is a device for dispensing a predetermined amount of liquid, a standard scale mark of, for example, 5 ml is required to be marked for dispensing a predetermined amount of 5 ml of reagent.
Further, the cross-section of the second reservoir may range from 0.2 square centimeters to 0.5 square centimeters.
The liquid inlet 1 is designed to enable the liquid reagent to be smoothly transferred from the container to the liquid extractor; the air guide port 2 is used for guiding out air in the liquid storage part, so that the air in the liquid storage part is ensured to be completely discharged, and the safe storage of the liquid reagent in the liquid storage part is ensured; the first liquid storage part 3 and the position of the first liquid storage part enable the liquid reagent to flow in more easily, and simultaneously, the storage condition of the liquid reagent is convenient to observe and control.
The second liquid storage part 4 is located above the first liquid storage part, so that the liquid reagent can be firstly stored in the first liquid storage part 3 after entering the liquid extractor, and then flows into the second liquid storage part 4, thereby realizing effective storage and control of the liquid reagent.
The design of the scale marks enables a user to easily know the liquid reagent reserves in the liquid extractor, so that accurate control and transfer are realized.
Both the first liquid storage portion 3 and the second liquid storage portion 4 are hollow annular columns, wherein the cross section of the first liquid storage cavity is larger than that of the second liquid storage cavity so as to increase the capacity of the liquid extractor, for example, if the capacity of the normal liquid extractor is 5 milliliters, if the capacity is 10 milliliters, the liquid extractor with the length twice is needed, which is easy to cause inconvenience in use, but in the embodiment, the capacity is increased by increasing the cross section of the first liquid storage cavity, the convenience in use is not affected, and the flowing of the liquid reagent when entering the liquid extractor 100 is smoother and faster.
The cross section of the second liquid storage cavity is smaller than that of the first liquid storage cavity, and a plurality of scale marks are arranged on the side wall of the second liquid storage part, so that the capacity precision of the scale marks with the same interval is more accurate, and the capacity control is more accurate.

Working process and principle:
Referring to fig. 3, when the liquid dispenser 100 is inserted into the container 200 containing the liquid reagent, the liquid reagent enters the first liquid storage part 3 and the second liquid storage part 4 through the liquid inlet 1, and the original air in the first liquid storage part 3 and the second liquid storage part 4 is discharged through the air guide opening 2. This process ensures that the gas within the extractor is completely expelled, thereby ensuring safe storage of the liquid reagent within the extractor.
The air guide port 2 is pressed by fingers, so that the liquid in the liquid storage part is maintained in the liquid storage part, then the liquid extractor is moved to a specified position, the air guide port 2 is opened by fingers, and the liquid reagent flows out from the liquid inlet to realize the transfer of the liquid. This design enables the user to achieve transfer of the liquid reagent through a simple operation, thereby improving convenience of operation.
Before transfer, the capacity in the liquid extractor can be adjusted by opening the air guide port 2, and when the liquid level reaches the scale mark, the capacity in the liquid extractor is marked, so that the liquid extractor is convenient to observe and control. Or when the liquid level reaches the standard scale mark 6, the capacity in the liquid extractor can be judged to reach the standard capacity requirement. The design enables a user to adjust the liquid reagent reserves in the liquid extractor according to actual demands, thereby realizing accurate control of the liquid reagent, and enabling the user to intuitively know the liquid reagent reserves in the liquid extractor, thereby realizing real-time monitoring of the liquid reagent.
When the liquid extractor 100 is inserted into the container 200 containing the liquid reagent, whether the liquid level in the container 200 reaches the corresponding scale mark can be observed, so as to control the capacity in the appliance.
The above embodiments are preferred examples of the present utility model, and are not intended to limit the scope of the present utility model.
