Description

Technical Field

[0001] This utility model relates to the field of amino acid analyzer technology, specifically to an automatic exhaust device for the liquid circuit of an amino acid analyzer. Background Technology

[0002] Amino acid analyzers play a crucial role in numerous fields such as biochemistry, food science, and pharmaceutical research and development. They can accurately determine the content and composition of various amino acids in samples, providing key data support for scientific research. However, the liquid path system in their operation presents many challenging problems. Traditional amino acid analyzers often face the problem of gas contamination during operation. Once bubbles are generated in the liquid path, they interfere with the normal separation process of amino acid components, altering their elution time and peak shape, leading to deviations in the detection results and severely affecting the accuracy and reliability of the data. This is a fatal flaw for scientific analysis that requires high precision.

[0003] Based on the above, the inventors have discovered the following problems: In most current amino acid analyzers, the liquid circuit venting device requires manual venting by the operator. The operator needs to frequently pause the instrument operation, open various valves in the liquid circuit, and remove air bubbles. This process is not only time-consuming and laborious, but also greatly reduces work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic venting device for the liquid circuit of an amino acid analyzer, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide an automatic air venting device for the liquid circuit of an amino acid analyzer, in order to solve the problem mentioned in the background art that most current air venting devices for the liquid circuit of amino acid analyzers require manual air venting by the operator. The operator needs to frequently stop the instrument operation, open various valves in the liquid circuit, and remove air bubbles. This process is not only time-consuming and laborious, but also greatly reduces work efficiency.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An automatic venting device for the liquid circuit of an amino acid analyzer includes a liquid circuit pipe. One end of the liquid circuit pipe is connected to a first liquid circuit connector, and the other end of the liquid circuit pipe is connected to a second liquid circuit connector. Both ends of the liquid circuit pipe are fitted with fixing sleeves. Fixing rods are installed on opposite sides of a pair of fixing sleeves. Connecting plates are installed at the bottom ends of adjacent sides of the pair of fixing sleeves. A striking mechanism for striking the liquid circuit pipe is installed at the top of the connecting plates. An venting pipe is connected to the middle of the top of the liquid circuit pipe, and an venting valve is installed at the top of the venting pipe.

[0008] Furthermore, the knocking mechanism includes a cage, the bottom end of the cage is fixedly connected to the top end of the connecting plate, a turntable is provided on one side of the cage, a first connecting shaft is installed at the top end of one side of the turntable, a connecting rod is rotatably connected to the outside of the first connecting shaft, one end of the connecting rod is rotatably connected to a second connecting shaft, and a knocking rod is installed at one end of the second connecting shaft.

[0009] The beneficial effect of adopting the above further solution is that through the settings of the turntable, the first connecting shaft, the connecting rod, the second connecting shaft and the knocking rod, the rotation of the turntable can make the knocking rod perform reciprocating motion to knock on the liquid pipeline.

[0010] Furthermore, a motor is installed on the other side of the cage, and the output end of the motor is connected to the inside of the turntable.

[0011] The beneficial effect of adopting the above further solution is that through the connection between the output end of the motor and the inside of the turntable, the electric rotation of the turntable is realized, so as to realize the automatic knocking action and greatly improve the exhaust efficiency.

[0012] Furthermore, a protective pad is installed at the top end of the knocking rod, and the protective pad is made of rubber.

[0013] The beneficial effect of adopting the above further solution is that by installing a protective pad at the top end of the knocking rod, it effectively avoids the direct scratching and impact of the knocking rod on the liquid pipeline, and at the same time reduces the knocking noise and optimizes the working environment.

[0014] Furthermore, a sliding sleeve is slidably connected to the outside of the knocking rod, and one side of the sliding sleeve is fixedly connected to one side of the cage.

[0015] The beneficial effect of adopting the above further solution is that by slidably connecting a sliding sleeve to the outside of the knocking rod, a stable sliding track is provided for the knocking rod.

[0016] Furthermore, the liquid pipeline is in a "U" - shaped style.

[0017] The beneficial effect of adopting the above further solution is that by the liquid pipeline being in a "U" - shaped style, it helps the bubbles to naturally gather at the upper position of the pipeline, which is convenient for subsequent centralized discharge.

[0018] Furthermore, a fixing plate is installed at one end of the fixing rod, and fixing holes are opened at the four corners on one side of the fixing plate.

[0019] The beneficial effect of adopting the above further solution is that by installing a fixing plate at one end of the fixing rod, it is convenient to fix the device at the designated position of the amino acid analyzer.
