Description

Technical Field

[0001] The utility model relates to the technical field of liquid metering devices, in particular to a rapid quantitative liquid metering device. Background Art

[0002] When doing experiments or in industrial production, a certain volume of liquid is measured, usually using a measuring cylinder, measuring cup, measuring bottle, etc. This method is simple to operate, but not accurate enough, and it is easy to spill the liquid, causing reagent contamination. When measuring a larger volume, it is not convenient enough and the error is large.

[0003] By searching, it was found that "A visual quantitative liquid metering device" disclosed by Chinese patent publication number CN218937474U was found, which proposed that the above device is not accurate enough for quantitatively measuring liquids, has a large error, and cannot be adjusted when the extracted liquid is excessive. The device starts the air pump to inject gas into the liquid storage tank body, so that the liquid in the liquid storage tank body flows into the discharge pipe and is discharged into the quantitative tank body through the liquid outlet. When the volume of liquid in the quantitative tank body is slightly larger than the required amount, the air pump is turned off, and the volume of liquid in the quantitative tank body can be seen from the volume of liquid in the quantitative pipe. The quantitative pipe is observed, and a certain amount of liquid in the quantitative tank body flows out of the reflux pipe to the liquid storage tank body. The volume of liquid in the quantitative tank body is adjusted to make the volume of liquid in the quantitative tank body reach the required amount, and finally the liquid in the quantitative tank body is discharged through the liquid outlet pipe. The device is easy to operate and can intuitively measure the quantitative liquid. Due to the provision of the quantitative pipe, the error is small. The return pipe is provided to facilitate the reflux of excess liquid and to adjust the amount of extracted liquid.

[0004] However, when using the device, it is necessary to inject a liquid volume greater than the required amount into the quantitative tank, and then adjust the volume of the internal liquid by observing the quantitative tube and discharging the excess liquid through the reflux pipe. The entire quantitative process is complicated to operate and cannot achieve rapid quantification. Utility Model Content
