A puncture liquid taking mechanism

Abstract

The invention discloses a puncturing and liquid extracting mechanism. The puncturing and liquid extracting mechanism comprises a puncturing mechanism and a pipette, wherein the puncturing mechanism is arranged above an opening of a liquid storage tank; the upper part of the pipette sleeves the opening of the liquid storage tank, and the lower part of the pipette is inserted into the liquid storage tank and extends to the bottom of the liquid storage tank; the puncturing mechanism comprises a puncturing pipe, a blocking head, a liquid discharge mechanism and a linear driving mechanism, wherein the blocking head is connected with the linear driving mechanism; the lower end of the puncturing pipe penetrates through the blocking head; the blocking head drives the puncturing pipe to be inserted into a central hole of the pipette and is communicated with the pipette to form a seal structure; the blocking head and the upper part of the pipette are sealed. According to the invention, the puncturing mechanism and the pipette are matched, and after the puncturing pipe and the pipette are communicated, a liquid in the liquid storage tank can be pressed into the pipette by the liquid discharge mechanism and is discharged via the puncturing pipe; the discharged liquid amount is automatically controlled by operators according to the actual situation, so that the requirements of operators can be met well; moreover, liquid extraction is convenient and rapid.

Description

technical field [0001] The invention relates to a puncture liquid taking mechanism. Background technique [0002] At present, in the supply industry of some liquid media, enterprises are selling in the form of quantitative filling, which cannot meet the requirements of buyers for the arbitrary purchase quantity. The way of capacity is to try to meet the different choices of buyers according to the demand. However, the use of the above method will increase the corresponding production and manufacturing costs for the enterprise, which will be passed on to the purchase cost of buyers, and increase the waste of resources. , if the company recycles the filling container, it will cause buyers to worry about food hygiene and safety. Secondly, the current sales method of filling a variety of different capacities has not actually reached the buyer's arbitrary amount. Requirements, there are still problems that cannot meet the needs of buyers well. Contents of the invention [000...

[0002] At present, in the supply industry of some liquid media, enterprises are selling in the form of quantitative filling, which cannot meet the requirements of buyers for arbitrary purchases. In response to the above problems, various filling methods have appeared on the market The way of capacity is to try to meet the different choices of buyers according to the demand. However, the use of the above method will increase the corresponding production and manufacturing costs for the enterprise, which will be passed on to the purchase cost of buyers, and increase the waste of resources. , if the company recycles the filling container, it will cause buyers to worry about food hygiene and safety. Secondly, the current sales method of filling a variety of different capacities has not actually reached the buyer's arbitrary amount. requirements, there are still problems that cannot meet the needs of buyers
