Description

Technical Field

[0001] This utility model relates to the field of liquid dispensing technology, specifically to an automatic precision liquid dispensing bottle. Background Technology

[0002] Precision dispensing bottles, as a commonly used laboratory instrument, offer high precision and stability, meeting the needs for accurate liquid dispensing in various experiments. They are bottles capable of precisely controlling the amount of liquid dispensed and are typically used in experiments in chemistry, biology, and medicine, especially in situations requiring precise control of liquid volume, such as drug development, clinical trials, and PCR reactions. However, most dispensing bottles on the market currently lack consistency in dispensing volume control. When performing multiple operations requiring equal dispensing volumes, the dispensing bottle cannot guarantee that the amount dispensed each time is exactly the same, which is particularly inconvenient in experiments or operations requiring consistency and fails to meet the requirements.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 10 This utility model provides a technical solution: an automatic precision liquid dispensing bottle, comprising: a sliding outer sleeve 1; an inner extraction tube 2 slidably disposed inside the sliding outer sleeve 1; a liquid extraction assembly disposed inside the inner extraction tube 2; an adjusting column 20 slidably disposed on one side of the inner extraction tube 2, and an opening 18 for cooperating with the adjusting column 20 being provided inside the sliding outer sleeve 1; a fixed base block 21 fixedly connected to the bottom of the adjusting column 20, and a tightening bolt 22 being threadedly connected inside the fixed base block 21; an extraction tube 12 fixedly connected to the bottom of the sliding outer sleeve 1, and a first check valve 13 installed on the extraction tube 12; and a liquid dispensing tube 14 fixedly connected to the bottom of the sliding outer sleeve 1, and a second check valve 15 installed on the liquid dispensing tube 14.

[0032] It is understood that this utility model, by rotating the tightening bolt 22 outward, releases the T-shaped slide groove 24, adjusts the height of the adjusting column 20 on the outside of the inner extraction tube 2, and adjusts the bottom of the fixed base block 21 and the indicator line 19 to adjust the height position of the adjusting column 20 and the fixed base block 21, adjusts the lifting height of the sliding sleeve 1 on the outside of the inner extraction tube 2, and controls the amount of liquid drawn. Rotating the tightening bolt 22 inward, the tightening bolt 22 re-tightens the T-shaped slide groove 24, and positions and installs the outer positioning blocks 9 on the outside of the mounting cylinder 6 with the positioning grooves 28 at the bottom of the mounting base sleeve 5. The limiting bolt 11 limits the installation of the outer positioning blocks 9 in the positioning grooves 28 through the limiting hole 10. The mounting cylinder 6 is installed and fixed on the inside of the mounting base sleeve 5. The fixing bottom ring 7 and the inner threaded cylinder 8, which are adapted to the outer threaded cylinder 30, are installed. The inner threaded cylinder 8 is connected to the outer threaded cylinder 30 at the top of the bottle body 29. During installation, the extraction tube 12 extends into the bottle body 29. By pulling the sliding outer sleeve 1 upward, the sliding outer sleeve 1 drives the fixed top bracket 25, piston rod 26, and piston body 27 to move upward. The piston body 27 moves within the inner extraction tube 2, drawing liquid from the bottle body 29 through the extraction tube 12. At this time, the first one-way valve 13 opens, and the second one-way valve 15 closes, drawing the liquid into the inner extraction tube 2 for storage. As the sliding outer sleeve 1 moves, it drives the port 18, causing the port 18 to move upward and contact the fixed top bracket 25. The fixed bottom block 21 limits the upward movement of the port 18 and the sliding outer sleeve 1, indicating that the amount of liquid extracted has been reached. Then, the liquid filling pipe 14 can be connected to the liquid filling container. The fixed top frame 25, piston rod 26 and piston body 27 are pressed down. The piston body 27 moves down and the liquid extracted in the inner extraction pipe 2 is discharged through the liquid filling pipe 14 and the second one-way valve 15. At this time, the first one-way valve 13 is closed and the second one-way valve 15 is opened.

One side of the T-shaped slider 23 is fixedly connected to the adjusting column 20, and one side of the sliding outer sleeve 1 is provided with indicator lines 19 that cooperate with the fixed base block 21 at equal intervals.

[0038] It is understood that the T-shaped slider 23 and the T-shaped groove 24 of this utility model limit the sliding. When the adjusting column 20 is adjusted outside the inner extraction tube 2, the adjusting column 20 drives the T-shaped slider 23 to slide within the T-shaped groove 24. When the adjusting column 20 moves, it drives the fixed base block 21 and the tightening bolt 22 to move. The bottom of the fixed base block 21 cooperates with the indicator line 19 to limit the movement position.
