[0040] The storage and quantitative dispensing of chemical reagents are fundamental processes in laboratories, chemical production, and scientific research. Traditional storage methods, such as reagent bottles and tanks, require repeated refilling, which can lead to evaporation, deterioration, or contamination. This poses safety hazards, especially for flammable, explosive, corrosive, or easily oxidized reagents, and can affect the occupational health of operators.

[0041] To address the technical problems of traditional storage methods such as reagent bottles and tanks, which require repeated filling and may lead to volatilization, deterioration, or contamination, this application provides a chemical reagent storage and quantitative transfer device. The device uses a reagent delivery component to extract chemical reagents from a reagent storage cabinet as needed and delivers them to a reagent transfer component. The reagent transfer component then transfers the chemical reagents to a predetermined location. This combination of the reagent delivery and transfer components not only enables automatic extraction of chemical reagents but also allows for precise control of the extraction volume.

[0042] Please refer to Figure 1 , Figure 1 This application provides a schematic diagram of a chemical reagent storage and quantitative transfer device.

[0043] like Figure 1As shown, the chemical reagent storage and quantitative transfer device includes a reagent storage cabinet 1, a reagent delivery assembly 2, and a reagent transfer assembly 3. The reagent storage cabinet 1 contains a storage tank 11 for storing chemical reagents. The reagent delivery assembly 2 is located inside the reagent storage cabinet 1 and is used to transport the chemical reagents stored in the reagent storage cabinet 1. The reagent transfer assembly 3 contains a transfer chamber for storing chemical reagents. The reagent transfer assembly 3 also has an input interface 31 connected to the transfer chamber. When the reagent transfer assembly 3 is placed on the reagent storage cabinet 1, the input interface 31 is detachably connected to the output end of the reagent delivery assembly 2, and the chemical reagents stored in the reagent storage cabinet 1 are transported to the transfer chamber through the reagent delivery assembly 2. In this embodiment, personnel can control the reagent delivery assembly 2 to extract chemical reagents from the reagent storage cabinet 1 as needed and transport the chemical reagents to the reagent transfer assembly 3. Personnel can use the reagent transfer assembly 3 to transfer the chemical reagents to a predetermined location, achieving not only automatic extraction of chemical reagents but also precise control of the extraction amount.

[0044] For example, in this embodiment, chemical reagents are stored in the reagent storage cabinet 1 in advance. When a certain amount of chemical reagents is needed, the reagent transfer component 3 is placed on the top of the reagent storage cabinet 1, and the input interface 31 is connected to the output end of the reagent delivery component 2 placed on the surface of the reagent storage cabinet 1. At this time, the data parameters of the reagent delivery component 2 are set according to the type and amount of chemical reagents needed by the personnel. The reagent delivery component 2 delivers the chemical reagents stored in the reagent storage cabinet 1 to the transfer chamber in the reagent transfer component 3 through the input interface 31 according to the set data parameters. After the amount of chemical reagents stored in the transfer chamber in the reagent transfer component 3 reaches the amount needed by the personnel, the personnel disconnect the connection between the input interface 31 and the reagent delivery component 2, and the chemical reagents can be transferred through the reagent transfer component 3, thereby completing the quantitative transfer of chemical reagents.

[0045] In some embodiments, such as Figure 2As shown, the chemical reagent storage and quantitative transfer device also includes an output connector 21, which is located at the top of the reagent storage cabinet 1 and communicates with the output end of the reagent delivery component 2. When the reagent transfer component 3 is placed at the top of the reagent storage cabinet 1, the output connector 21 is plugged into the input interface 31. It can be understood that in this embodiment, when personnel need to extract chemical reagents from the reagent storage cabinet 1, they place the reagent transfer component 3 at the top of the reagent storage cabinet 1. When the reagent transfer component 3 is placed at the top of the reagent storage cabinet 1, the input interface 31 on the reagent transfer component 3 is plugged into the output interface at the top of the reagent storage cabinet 1, thereby enabling the reagent delivery component 2 to transfer the chemical reagents stored in the reagent storage cabinet 1 to the transfer chamber within the reagent transfer component 3. This reduces the connection difficulty between the reagent transfer component 3 and the reagent storage cabinet 1, allowing personnel to complete the quantitative transfer of chemical reagents more quickly.

[0046] For example, such as Figure 3 As shown, in this embodiment, the output connector 21 is a male connector, and the input interface 31 is a female connector adapted to the output connector 21. The output connector 21 is located at the top of the reagent storage cabinet 1, and one end of the output connector 21 protrudes from the reagent storage cabinet 1. When the reagent transfer component 3 is placed at the top of the reagent storage cabinet 1, the end of the output connector 21 protruding from the reagent storage cabinet 1 extends into the input interface 31 and is then engaged with the input interface 31.

[0047] In another optional embodiment, the output connector 21 is disposed on the reagent storage cabinet 1, and the input interface 31 is connected to the actual transfer component through a connecting pipe. The input interface 31 is suspended in the air, and the connecting pipe is a flexible pipe or a universal pipe. After the reagent transfer component 3 is placed on the top of the reagent storage cabinet 1, the position of the suspended position of the input interface 31 is adjusted so that the input interface 31 can be connected to the output connector 21 on the reagent storage cabinet 1.

[0048] In some embodiments, such as Figure 3 As shown, the chemical reagent storage and quantitative transfer device also includes a first sealing component 32. The first sealing component 32 is used to control the opening and closing of the input interface 31. When the chemical reagent is transported into the transfer chamber through the reagent delivery component 2, the first sealing component 32 controls the input interface 31 to open. In this embodiment, the first sealing component 32 can not only prevent the chemical reagent in the reagent transfer component 3 from leaking, but also realize the automatic sealing of the reagent transfer component 3 through the first sealing component 32, further reducing the operation difficulty of the chemical reagent storage and quantitative transfer device.

[0049] For example, in some optional embodiments, the first blocking assembly 32 includes a first blocking member 321, a first spring member 322, and a retaining member. The retaining member is disposed on the output connector 21. The first blocking member 321 and the first spring member 322 are both disposed within the input interface 31. The first spring member 322 is disposed on the side of the first blocking member 321 away from the opening of the input interface 31. The first spring member 322 abuts against the first blocking member 321, blocking the opening of the input interface 31. When the input interface 31 is connected to the output connector 21, the output interface... The abutment on the head 21 extends into the input interface 31 and pushes the first sealing member 321 to move away from the opening of the input interface 31, thereby opening the opening of the input interface 31. When it is necessary to seal the input interface 31, simply disconnect the connection between the input interface 31 and the output connector 21. At this time, the first sealing member 321 loses the force of the abutment, allowing the first spring member 322 to drive the first sealing member 321 to move towards the opening of the input interface 31, thereby sealing the input interface 31 by the first sealing member 321.

[0050] For example, such as Figure 3 As shown, in some alternative embodiments, the first blocking component 32 includes a first blocking member 321 and a first spring member 322. Both the first blocking member 321 and the first spring member 322 are disposed within the input interface 31. The first spring member 322 is disposed on the side of the first blocking member 321 away from the opening of the input interface 31. The first spring member 322 abuts against the first blocking member 321 to block the opening of the input interface 31. During use, when the reagent delivery component 2 delivers chemical reagents from the reagent storage cabinet 1 to the reagent transfer component 3, the chemical reagents pass through the input interface 31 and the output connector 21. At this time, the first blocking member 321 moves away from the opening of the input interface 31 under the impact force of the chemical reagents, thereby allowing the opening of the input interface 31 to open. After the reagent delivery component 2 stops delivering chemical reagents, the first blocking member 321 loses the impact force of the chemical reagents and moves towards the opening of the input interface 31 under the action of the first spring member 322, thereby allowing the input interface 31 to be blocked by the first blocking member 321.

[0051] In this embodiment, as Figure 3As shown, the first sealing element 321 is spherical, and the opening of the input interface 31 has a circular opening. When the first sealing element 321 blocks the opening of the input interface 31, part of the first sealing element 321 passes through the opening of the input interface 31 and abuts against the opening of the input interface 31. It can be understood that the spherical first sealing element 321 forms a ring-shaped line contact or a small-area surface contact with the opening of the input interface 31. This contact method can generate high specific pressure (pressure per unit area) under the action of spring preload, effectively crushing small impurities or compensating for microscopic unevenness of the surface, achieving a tight seal. Secondly, the first sealing element 321 can slightly roll or finely adjust its position under the action of spring force, automatically adapting to small geometric deviations of the opening of the input interface 31 (such as different axiality or roundness errors), compensating for manufacturing or installation errors, and improving sealing consistency.

[0052] In some embodiments, such as Figure 3 As shown, a sealing strip 323 is provided at the edge of the opening of the input interface 31. When the first sealing member 321 blocks the opening of the input interface 31, the sealing strip 323 is tightly attached to the first sealing member 321. In this embodiment, the sealing strip 323 (such as silicone, fluororubber, EPDM, etc.) undergoes elastic deformation under the action of spring preload, fully filling the microscopic unevenness (machining marks, micro-scratches) between the ball and the metal surface of the valve seat, eliminating leakage paths, and achieving near-zero leakage static sealing. Secondly, the elasticity of the strip can absorb the vibration energy generated by the input interface 31 during use, preventing the first sealing member 321 from "jumping away" from the opening of the input interface 31 due to high-frequency micro-vibration, and avoiding instantaneous leakage under vibration conditions.

[0053] In some embodiments, such as Figure 1 As shown, the reagent transfer assembly 3 includes a tray 33 and a reagent output bottle 34. The reagent output bottle 34 is disposed on the tray 33, and the input interface 31 is disposed on one side of the tray 33 and communicates with the transfer cavity inside the reagent output bottle 34. It can be understood that in this embodiment, the reagent output bottle 34 is used to store chemical reagents, while the tray 33 is used for personnel to move the reagent output bottle 34. During use, after the reagent transfer assembly 2 transfers the chemical reagents from the reagent storage cabinet 1 to the reagent output bottle 34, personnel move the reagent output bottle 34 via the tray 33, reducing the difficulty of transferring chemical reagents. Furthermore, multiple reagent output bottles 34 can be disposed on the tray 33, allowing personnel to simultaneously transfer multiple different types of chemical reagents.

[0054] In some embodiments, such as Figure 2As shown, the reagent transfer assembly 3 also includes a mixing tank 35 and a distributor 36. The mixing tank 35 is mounted on the tray 33. A distributor 36 is also provided between the reagent output bottle 34 and the input interface 31. The first end of the distributor 36 is connected to the input interface 31, the second end of the distributor 36 is connected to the reagent output bottle 34, and the third end of the distributor 36 is connected to the mixing tank 35. The distributor 36 is used to control the flow direction of the chemical reagents transported by the reagent transfer assembly 2. It can be understood that when personnel quantitatively transfer chemical reagents, they adjust the flow direction of the chemical reagents in the reagent transfer assembly 2 through the distributor, so that different types of chemical reagents can be collected in the mixing tank 35 for mixing, thereby enabling the preparation of different mixed liquids as needed. For example, when it is necessary to prepare a 25% concentration sulfuric acid solution, first control the reagent transfer assembly 2 to deliver one part of sulfuric acid into the mixing tank 35, and then control the reagent transfer assembly 2 to deliver three parts of water into the mixing tank 35. After the one part of sulfuric acid and the three parts of water are mixed in the mixing tank 35, a 25% concentration sulfuric acid solution is obtained.

[0055] In some embodiments, the reagent transfer assembly 3 further includes a rotary paddle disposed inside the mixing tank 35 for stirring the liquid inside the mixing tank 35. By stirring the liquid inside the mixing tank 35 with the rotary paddle, the liquid inside the mixing tank 35 can be fully mixed.

[0056] In some embodiments, the chemical reagent storage and quantitative transfer device further includes a level gauge, which is disposed in the transfer chamber to detect the liquid level height in the transfer chamber. In this embodiment, the liquid level height in the transfer chamber can be detected by the level gauge, thereby realizing the quantitative transfer of chemical reagents.

[0057] For example, in this embodiment, the level gauge is electrically connected to the reagent delivery assembly 2. The reagent delivery assembly 2 can detect the output amount of chemical reagents in real time through the level gauge, thereby enabling more precise control of the quantitative transfer of chemical reagents.

[0058] In some embodiments, the chemical reagent storage and quantitative transfer device further includes a ventilation device 4, which is installed in the reagent storage cabinet 1 to create a ventilation environment when the chemical reagent is transported into the transfer chamber. It is understood that after the reagent transport assembly 2 completes the transport of the chemical reagent and disconnects the input interface 31 from the output connector 21, there will inevitably be residual chemical reagent in the output connector 21. Some chemical reagents are volatile, and the gases released by these chemical reagents may pose a hazard to the human body. Therefore, for the health of the human body, the ventilation device 4 creates a ventilation environment when the chemical reagent is transported into the transfer chamber, thereby expelling the volatile gases through the ventilation device 4 and thus protecting the health of the human body.

[0059] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
