Description

Technical Field

[0001] This utility model relates to the field of experimental container technology, specifically a negative pressure experimental container dosing device. Background Technology

[0002] In scientific research experiments, many experiments need to be conducted under negative pressure to simulate specific experimental conditions or to prevent harmful gases generated during the experiment from leaking into the surrounding environment. Performing chemical dosing operations within a negative pressure experimental container is a challenging task.

[0003] Traditional methods of adding chemicals often make it difficult to precisely control the dosage, and the negative pressure environment inside the experimental container can be easily disrupted during the process. For example, directly opening the container to add chemicals will allow outside air to enter rapidly, causing the negative pressure to disappear and affecting the accuracy and stability of the experiment.

[0004] A negative pressure experimental container dosing device disclosed in Chinese utility model patent application CN202322233213.6 includes a sealed container with a rubber stopper installed at the upper port, and a central shaft passing longitudinally through the rubber stopper, with a support platform connected to the lower end of the central shaft. The support platform includes at least two support plates of unequal width located on different sides of the central shaft. Although this negative pressure experimental container dosing device improves the efficiency of experimental operations and the accuracy of experimental results, it has the disadvantage of requiring multiple reagents to be added to the container in stages, which easily disrupts the negative pressure environment inside the container, and it also prevents the mixing of multiple reagents before addition.

[0018] 1. This negative pressure experimental container dosing device, through the arrangement of a main pipe, a first valve, a mixing pipe, a second valve, a fixed pipe, a soft stopper, a push rod, a vacuum valve, and a negative pressure detector, enables the device to minimize the entry of outside air into the device during use, effectively maintaining the negative pressure environment inside the container, ensuring the stability of the experiment, and effectively solving the problem that the negative pressure environment inside the experimental container is easily disrupted during the dosing process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 5This utility model provides a technical solution: a negative pressure experimental container dosing device, including a main pipe 1, a first valve 2 fixedly connected to the bottom of the main pipe 1, a mixing pipe 3 fixedly connected to the bottom of the first valve 2, a second valve 4 fixedly connected to the bottom of the mixing pipe 3, a fixed pipe 5 fixedly connected to the bottom of the second valve 4, a soft plug 6 inside the main pipe 1, a fixed block 7 fixedly connected to the inner side of the soft plug 6, a rotating block 8 rotatably connected to the top of the fixed block 7, ventilation holes 10 opened inside both the rotating block 8 and the fixed block 7, a push rod 9 fixedly connected to the top of the rotating block 8, multiple through holes opened on the outer side of the main pipe 1 and multiple dosing pipes 11 fixedly connected thereto, graduation lines on the outer side of the dosing pipes 11, and a first stirring shaft 12 rotatably connected inside the mixing pipe 3. A second stirring shaft 13 is rotatably connected inside the mixing tube 3. A negative pressure detector 18 is provided on the side of the mixing tube 3, and the detection end of the negative pressure detector 18 is located inside the fixed tube 5. A vacuum valve 17 is provided on the side of the mixing tube 3, and the vacuum valve 17 is connected to the fixed tube 5. Through the arrangement of the main tube 1, the first valve 2, the mixing tube 3, the second valve 4, the fixed tube 5, the soft plug 6, the push rod 9, the vacuum valve 17, and the negative pressure detector 18, the device can minimize the amount of outside air entering the device during use, effectively maintain the negative pressure environment inside the container, ensure the stability of the experiment, and effectively solve the problem that the negative pressure environment inside the experimental container is easily destroyed during the dosing process. For example, if the container is opened directly for dosing, outside air will quickly enter, causing the negative pressure to disappear and affecting the accuracy and stability of the experiment.

[0030] In use, the fixed tube 5 is fixedly connected to the negative pressure container. Then, the medicine to be added is placed into the dosing tube 11. At this time, the soft stopper 6 is located inside the main tube 1 and at the connection between the dosing tube 11 and the main tube 1. The medicine is located inside the dosing tube 11. The user can adjust the amount of medicine by the scale lines on the outside of the dosing tube 11. After adjustment, pull the push rod 9 to make the fixed block 7 lift the soft stopper 6, and then the medicine enters the main tube 1. Then push the push rod 9 to make the soft stopper 6 descend inside the main tube 1, thereby reducing the space between the soft stopper 6 and the main tube 1. Then rotate the push rod 9 to make the rotating block 8 rotate. After the rotating block 8 rotates, it is fixed. The positions of the vent holes 10 inside blocks 7 and 8 are changed to reduce the amount of air entering. Then, the first valve 2 is opened to allow the reagent to enter the mixing tube 3. At this time, the first valve 2 is closed and the second valve 4 is opened to allow the reagent to fall into the negative pressure container through the fixed tube 5. Then, the user can observe the value inside the negative pressure container through the negative pressure detector 18. When the value is not up to standard, the vacuum valve 17 can be activated to adjust the negative pressure. This effectively solves the problem that the negative pressure environment inside the experimental container is easily damaged during the dosing process. For example, if the container is opened directly for dosing, outside air will enter quickly, causing the negative pressure to disappear and affecting the accuracy and stability of the experiment.

[0031] Example 2

[0032] Please see Figure 1 and 6 This utility model provides a technical solution: a negative pressure experimental container dosing device. A first gear 14 and a second gear 15 are provided on the side of the mixing tube 3. The first gear 14 meshes with the second gear 15. The first gear 14 is fixedly connected to a first stirring shaft 12, and the second gear 15 is fixedly connected to a second stirring shaft 13. A motor 16 is fixedly connected to the side of the mixing tube 3. The output shaft of the motor 16 passes through the mixing tube 3 and is fixedly connected to the first stirring shaft 12. Through the arrangement of multiple dosing tubes 11, the first gear 14, the second gear 15, the first stirring shaft 12, the second stirring shaft 13, and the motor 16, the device allows multiple agents to enter the mixing tube 3 simultaneously during use, and then mix the agents. This allows multiple agents to enter the negative pressure container simultaneously, effectively solving the problem that multiple agents need to be added to the container in stages, which easily disrupts the negative pressure environment inside the container, and that it is impossible to mix multiple agents before adding them.

[0033] In use, multiple drugs are placed into the inside of multiple dosing tubes 11 to measure each drug separately. Then, the multiple drugs enter the mixing tube 3, and the motor 16 is started. The motor 16 causes the first stirring shaft 12 to rotate, which in turn causes the first gear 14 to drive the second gear 15 to rotate, thereby causing the second stirring shaft 13 to rotate. During rotation, the first stirring shaft 12 rotates in the opposite direction to the second stirring shaft 13, thus stirring the drugs. After stirring, the multiple drugs can be put into the negative pressure container together. This effectively solves the problem that when adding multiple drugs into the negative pressure container, they need to be added in multiple times, which can easily destroy the negative pressure environment inside the container, and it is not possible to mix the multiple drugs in advance before adding them.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
