Some improved models are equipped with a coarse volume structure. The basic function of these devices is to provide users with a convenient way to dispense liquid and to achieve a certain degree of quantitative dispensing through a fixed volume or visual reading to meet general experimental or production needs.

[0004] While conventional chemical reagent and auxiliary agent containers currently in use can extract reagents, they cannot provide a metering valve and are difficult to precisely control the volume of different amounts dispensed. Therefore, a chemical reagent and auxiliary agent container with a metering valve is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a chemical reagent auxiliary container with a quantitative dispensing valve, comprising an outer cylinder 1, which serves as the main outer shell of the container and primarily functions to contain the chemical reagent auxiliary. A piston 16 is slidably connected to the inner side of the outer cylinder 1, which can change the internal volume of the outer cylinder 1 by sliding within it, thereby controlling the extraction and dispensing of the reagent auxiliary and ensuring that the basic operation of quantitative dispensing can be realized. A push rod 5 is fixedly connected to the inner side of the piston 16, which is a key component for the operator to control the movement of the piston 16. By pushing or pulling the push rod 5, the operator can drive the piston 16 to slide synchronously within the outer cylinder 1. A sealing plug 15 is fixedly connected to the bottom end of the push rod 5, which is made of a material with good sealing properties. Its main function is to tightly fit against the inner wall of the outer cylinder 1 during the movement of the piston 16, preventing the chemical reagent auxiliary in the outer cylinder 1 from leaking from the gap between the piston 16 and the outer cylinder 1, ensuring the sealing of the container and ensuring that the reagent auxiliary can be stably retained and quantitatively dispensed. When the connecting groove 22 and the conduit 21 are connected simultaneously, solvent is prevented from entering the outer cylinder 1. Conduits 21 are fixedly connected to both sides of the outer cylinder 1. The conduits 21 fixed on both sides of the outer cylinder 1 are channels for chemical reagents and auxiliaries to enter and exit the outer cylinder 1. The left conduit 21 can be used to draw external reagents and auxiliaries into the outer cylinder 1, while the right conduit 21 can cooperate with subsequent structures to deliver a quantitative amount of reagents and auxiliaries out of the outer cylinder 1. The two conduits 21 together ensure the smooth flow path of the reagents and auxiliaries in the container. The outer periphery of the push rod 5 is slidably connected to the inner side of the conduit 21. A connecting groove 22 is opened on the inner side of the middle end of the push rod 5. The inner end of the conduit 21 is slidably connected to the outer side of the connecting groove 22, which is a groove structure for connecting the two conduits 21. When the push rod 5 drives the piston 16 to slide to a specific position, the connecting groove 22 can be connected to the conduits 21 on both sides of the outer cylinder 1, providing a channel for the flow of reagents and auxiliaries between the conduits 21 and the outer cylinder 1. This is important for realizing quantitative dispensing. The conduits 21 are slidably connected to the outer side of the connecting groove 22 on opposite sides.

[0034] Reference Figures 3-5A connector 12 is fixedly connected to the front of the front conduit 21. The connector 12 serves as a transition component connecting the conduit 21 and the graduated tube 14, preventing reagent leakage due to gaps that might occur from direct connection between the two components. The rear conduit 21 is fixedly connected to the outer bottom of the outer cylinder 1. A graduated tube 14 is fixedly connected to the left side of the connector 12. The outer side of the graduated tube 14 has clear graduation markings. Operators can visually understand the volume of reagent flowing through this component by observing the liquid level of the chemical reagent in the graduated tube 14. An adjusting tube 9 is slidably connected to the left side of the graduated tube 14. By sliding the adjusting tube 9 to the left side of the graduated tube 14, the relative position of the adjusting tube 9 and the graduated tube 14 can be changed, thereby adjusting the channel length and space size of the chemical reagent in the entire flow path. Operators can slide the adjusting tube 9 to the appropriate position according to the actual required dosage of reagent, providing structural support for precise control of the flow rate and dosage of reagent, ensuring that each use is safe and effective. The dosage of the reagents and auxiliaries used meets the requirements. A ball valve 13 is rotatably connected to the inside of the regulating tube 9. The rotation of the ball valve 13 inside the regulating tube 9 can change the alignment degree between the through hole on its core and the internal channel of the regulating tube 9. When the through hole is completely aligned with the channel, the chemical reagents and auxiliaries can pass through the regulating tube 9 at the maximum flow rate. When the through hole is partially aligned or completely misaligned with the channel, the flow rate of the reagents and auxiliaries will be reduced accordingly or completely blocked. By rotating the ball valve 13, the flow and cut-off of the reagents and auxiliaries, as well as the flow rate, can be flexibly controlled. A control turntable 10 is fixedly connected to the top of the ball valve 13. The control turntable 10 provides a convenient operating position for the operator to rotate the ball valve 13. The operator can rotate the control turntable 10 by hand to drive the ball valve 13 to rotate synchronously. Compared with directly rotating the ball valve 13, the control turntable 10 increases the force-bearing area during operation, allowing the operator to control the rotation angle of the ball valve 13 more effortlessly and accurately, thereby more accurately adjusting the flow rate of the chemical reagents and auxiliaries or realizing the opening and closing of the channel.

[0035] Reference Figures 1-5A baffle 17 is fixedly connected to the inner side of the outer cylinder 1. This baffle acts as a limiting component, restricting the sliding range of the piston 16 within the outer cylinder 1 and preventing it from sliding excessively upwards and detaching from the outer cylinder 1. The top side of the sealing plug 15 abuts against the bottom side of the baffle 17. When the piston 16 slides upwards to the point where the sealing plug 15 contacts the baffle 17, it can no longer move upwards. A one-way valve 19 is fixedly connected to the inner bottom of the outer cylinder 1. This valve has a one-way flow characteristic, allowing only the chemical reagents and additives inside the outer cylinder 1 to flow downwards into the lower conical tube 2, while preventing external air or the reagents and additives below from flowing back into the outer cylinder 1. This ensures the purity of the reagents and additives inside the outer cylinder 1, avoids contamination, and also ensures the accuracy of the dosage of reagents and additives discharged each time. The bottom of the outer cylinder 1... A tapered tube 2 is fixedly connected to the side of the outer cylinder 1. Its main function is to collect and guide the chemical reagents and auxiliaries discharged from the outer cylinder 1, allowing them to flow towards the nozzle 3 below, preventing them from splashing during discharge. The structure of the tapered tube 2 also slows down the flow rate of the reagents and auxiliaries, making the discharge process smoother. A nozzle 3 is fixedly connected to the bottom of the tapered tube 2; this is the final discharge container for the chemical reagents and auxiliaries. The nozzle 3 typically has a small outlet design, discharging the reagents and auxiliaries in a fine stream. A top plate 18 is fixedly connected to the top of the outer cylinder 1, serving as a sealing component at the top. It prevents external dust and impurities from entering the outer cylinder 1 and contaminating the reagents and auxiliaries. The inner side of the top plate 18 is slidably connected to the outer periphery of the push rod 5, and the top side of the push rod 5 is fixedly connected to... A push handle 6 is attached to the outer side of the outer cylinder 1, and a handle 4 is fixedly connected to the outer side of the outer cylinder 1. This is a component designed for the operator to hold the container easily. When using the container to draw or discharge reagents, the operator can more stably control the position of the container by holding the handle 4. The inner side of the handle 4 is fixedly connected to the outer side of the right-side conduit 21 of the outer cylinder 1, which can provide some support and protection for the right-side conduit 21 to prevent damage due to accidental collisions and ensure the normal flow function of the conduit 21. A fixing ring 11 is fixedly connected to the left side of the regulating tube 9, and its main function is to further guide the flow of reagents. A guide tube 8 is fixedly connected to the left side of the fixing ring 11. A locking device 7 is rotatably connected to the top side of the left end of the guide tube 8. This is a component used to fix the convenient container 20. The connection between the locking device 7 and the convenient container 20 can be adjusted by rotation. When the convenient container 20 needs to be placed or removed, rotating the locking device 7 will open the fixing structure. After the convenient container 20 is placed in place, rotating the locking device 7 in the opposite direction will firmly fix it, preventing the convenient container 20 from moving or tipping over when receiving reagents and auxiliaries. The convenient container 20 is rotatably connected to the top side of the locking device 7. It is a small container used to temporarily receive chemical reagents and auxiliaries flowing out from the guide tube 8. Its "convenience" is reflected in its small size and light weight, making it convenient for operators to take and transfer at any time. The rotatable connection also allows the convenient container 20 to be easily removed from the locking device 7 after it is filled with reagents and auxiliaries, improving the convenience of operation. It is suitable for scenarios where reagents and auxiliaries need to be taken out in small amounts in multiple times.

[0036] Working principle: First, the operator holds the handle 4 on the outside of the outer cylinder 1. The handle 4 provides a gripping fulcrum for the hand, preventing the container from shaking during operation. It also supports and protects the conduit 21 fixed on the right side of the outer cylinder 1, preventing the conduit 21 from being damaged by accidental collision, thereby stabilizing the outer cylinder 1 of the container body. Next, rotate the control dial 10 on the top side of the regulating tube 9. Since the control dial 10 is fixedly connected to the ball valve 13 inside the regulating tube 9, rotating the dial will synchronously drive the ball valve 13 to rotate until the through hole of the ball valve 13 is completely aligned with the internal channel of the regulating tube 9, so that the regulating tube 9, the graduated tube 14, and the guide tube 8 form a smooth reagent flow path. At the same time, it is necessary to confirm that the push rod 5 is in the initial position. At this time, the piston 16 is close to the bottom of the outer cylinder 1. Then, according to the quantitative needs of this chemical reagent, the operator slides the regulating tube 9 along the left side of the graduated tube 14 by hand, and adjusts the reagent holding space by changing the relative distance between the two: if the dosage is small, the distance is shortened to reduce the space, and if the dosage is large, the distance is widened to expand the space. During the process, the temporary reagent amount on the left side of the outer cylinder 1 can be accurately determined by the clear scale on the outside of the graduated tube 14. After the dosage is determined, rotate the control dial 10 again to drive the ball valve 13 to rotate in the opposite direction, so that the through hole is completely misaligned with the channel of the regulating tube 9, and close the ball valve 13 to prevent temporary reagent leakage on the left side.

[0037] Subsequently, the push rod 5 slides under the guidance of the top plate 18 on the top side of the outer cylinder 1, simultaneously driving the piston 16 fixed at the bottom to move to the lower part of the outer cylinder 1. At this time, the connecting groove 22 on the inner side of the push rod 5 connects the left conduit 21 and the graduated tube 14 simultaneously with the adapter tube 12. The conduit 21 is connected, and the reagent temporarily stored in the adapter tube 12 and the graduated tube 14 flows along the connecting groove 22 to the right conduit 21. The sealing plug 15 on the inner side of the piston 16, made of a high-sealing material, tightly fits against the inner wall of the outer cylinder 1, sealing the reagent in the right conduit 21, achieving secondary flow control, and preventing reagent leakage or turbulence. Next, the push handle 6 is pulled up, driving the push rod 5 and the piston 16 to move upward inside the outer cylinder 1. The upward movement of the piston 16 causes the sealing plug 15 on the inner side of the piston 16 to move upward. 5. Moving upwards, the bottom channel of the reagent in the right conduit 21 is opened, allowing the reagent to smoothly enter the outer cylinder 1. At the same time, because the ball valve 13 is closed, the reagent on the left is isolated to prevent mixing and affecting the quantitative accuracy. In addition, the baffle 17 on the inner side of the outer cylinder 1 restricts the upward movement range of the piston 16 to prevent it from detaching from the outer cylinder 1. Finally, the push handle 6 is pushed down again, causing the piston 16 to move down and compress the internal space of the outer cylinder 1, increasing the air pressure. Under the pressure, the quantitative reagent in the outer cylinder 1 opens the one-way valve 19 at the bottom of the outer cylinder 1, allowing the reagent to flow downwards only to prevent reverse contamination. Then, it passes through the conical tube 2 on the bottom side of the outer cylinder 1. The conical tube 2 can collect the reagent, slow down the flow rate and prevent splashing. Finally, the reagent is discharged through the nozzle 3 on the bottom side of the conical tube 2, completing the quantitative dispensing operation.
