Description

Technical Field

[0001] This utility model relates to the field of liquid storage tank technology, specifically to a volatile-resistant sealed liquid storage tank. Background Technology

[0002] In the field of laboratory liquid storage, traditional liquid storage devices often face the problem of easy loss of volatile liquids and environmental pollution. Most open or simply sealed liquid storage tanks cannot completely prevent the liquid from contacting the air. Especially for low-boiling-point reagents such as ethanol and ether, the concentration will change due to evaporation in a short time, affecting the accuracy of the experiment. At the same time, the evaporating gases may also react with other substances in the experimental environment, posing safety hazards.

[0003] The existing multi-slot liquid storage device design also has obvious defects: some liquid storage slots use a uniform sealing cover, which cannot achieve independent sealing of each slot. When one liquid is taken out, the liquid in other slots will be exposed at the same time. In addition, the device lacks temperature control function. Relying solely on sealing is not enough to suppress the violent evaporation of liquid in high-temperature environments. Furthermore, the bottom of most slots is designed to be flat, making it difficult to completely remove residual liquid and resulting in reagent waste.

[0004] Furthermore, the impractical design of the sealing cap also limits the user experience. Traditional sealing caps lack a dedicated support structure after removal, and the sealing surface is in direct contact with the work surface, making it prone to contamination with impurities. When the cap is closed again, it can contaminate the liquid in the tank. Some caps are also prone to tipping over due to uneven weight distribution, increasing operational risks. These problems make it difficult for existing devices to meet the requirements of sealing, convenience, and safety for liquid storage in precision experiments. Summary of the Invention

A slot is provided at the bottom of the shell, and a drawer box inside the shell is slidably connected to the slot. A pull rod is fixedly connected to the outer wall of the drawer box. A sealing cover is provided at the top of the shell, and a pull handle is fixedly connected to the sealing cover. A plurality of sealing blocks are fixedly connected below the sealing cover, and support legs are fixedly connected to the two side walls of the sealing cover.

[0007] Furthermore, the upper part of the liquid storage tank is rectangular, while the lower part is integrally formed into a conical area.

[0008] Furthermore, the drawer box is located at the bottom of the liquid storage tank in the housing, without contacting it, and ice packs are temporarily placed in the drawer box.

[0015] 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.

[0016] Example like Figure 1-4As shown, an embodiment of this utility model proposes an anti-volatile sealed liquid storage tank, including a shell 1. The shell 1 has a plurality of liquid storage slots 2 integrally formed inside. The shell 1 is an integral support structure. The integrally formed liquid storage slots 2 inside it directly serve as liquid storage space. The upper rectangular design facilitates liquid injection, and the lower conical area 3 allows residual liquid to naturally converge, reducing liquid adhesion and waste. The two are combined to form a basic liquid storage unit. The lower part of the housing 1 is provided with a slot 4, and a drawer box 5 inside the housing 1 is slidably connected in the slot 4. The slot 4 at the bottom of the housing 1 provides a sliding track for the drawer box 5. The drawer box 5 can be pushed into the housing 1 along the slot 4 and located directly below the liquid storage tank 2. By placing an ice pack in the drawer box 5, the temperature of the liquid in the liquid storage tank 2 is reduced by using a low-temperature environment, which further inhibits liquid evaporation. A pull rod 6 is fixedly connected to the outer wall of the drawer box 5. The pull rod 6 facilitates the pulling out of the drawer box 5 and makes it easy to replace the ice pack to maintain the low temperature effect. The top of the housing 1 is provided with a sealing cover 7, and a pull handle 8 is fixedly connected to the sealing cover 7. Several sealing blocks 9 are fixedly connected below the sealing cover 7. The sealing cover 7 covers the top of the housing 1. The number, size and shape of the sealing blocks 9 fixed below it are adapted to the liquid storage tank 2. When the sealing cover 7 is closed, the sealing blocks 9 are just embedded in the liquid storage tank 2 to form a tight seal, block the liquid evaporation channel and achieve the core anti-evaporation sealing effect. The sealing cover 7 has support legs 10 fixedly connected to both sides of its two sides; four L-shaped support legs 10 are symmetrically arranged on both sides of the sealing cover 7. When the sealing cover 7 is removed, the support legs 10 can make the sealing cover 7 stably placed on the experimental table, avoiding the sealing block 9 from directly contacting the table and causing contamination. At the same time, the handle 8 makes it easy to put the sealing cover 7 in and out, ensuring convenient operation.

[0017] The working principle of this anti-volatile sealed liquid storage tank is as follows: The liquid storage tank 2 inside the shell 1 is used to store experimental liquids. Its rectangular upper part and conical lower part 3 structure facilitates liquid injection and residual liquid collection. The sealing cover 7 seals the liquid storage tank 2 through the sealing blocks 9 below that are adapted to the number, size and shape of the liquid storage tank 2, thereby achieving a seal to prevent liquid evaporation. The drawer box 5, which is slidably connected in the slot 4 at the bottom of the shell 1, can hold ice packs to help suppress liquid evaporation using a low temperature environment. The drawer box 5 can also be replaced by pulling it out with a pull rod 6. The handle 8 on the sealing cover 7 makes it easy to put on and take off. The L-shaped support legs 10 on both sides of the sealing cover 7 can stably support it on the experimental table when the sealing cover 7 is removed. The overall combination meets the needs of laboratory for the sealed storage of volatile liquids.

[0018] like Figure 2As shown, in some embodiments, the upper part of the liquid storage tank 2 is rectangular, and the lower part is an integrally formed conical area 3. The upper rectangular structure facilitates the injection of liquid into the tank during experimental operations and is compatible with common pipetting tools, such as pipettes and beakers, for tilting or dripping, reducing liquid spillage. The lower conical area 3 allows residual liquid in the liquid storage tank 2 to naturally converge to the bottom, reducing the amount of liquid adhering to the tank wall, which reduces reagent waste and facilitates subsequent cleaning or complete removal of residual liquid. It is especially suitable for storage and use scenarios with small amounts of liquid and is compatible with the anti-evaporation and high-efficiency storage functions of the overall liquid storage tank.

[0019] like Figure 3 As shown, in some embodiments, the drawer box 5 is located at the bottom of the liquid storage tank 2 within the housing 1, without contacting it. Ice packs are temporarily placed in the drawer box 5. The slot 4 at the bottom of the housing 1 provides a sliding installation channel for the drawer box 5, allowing it to be stably placed at the bottom of the liquid storage tank 2 without direct contact. This non-contact layout avoids rigid collisions between the drawer box 5 and the liquid storage tank 2, and also allows the low temperature of the ice packs to be transferred to the liquid storage tank 2 through air conduction. This utilizes the low temperature environment to reduce the evaporation rate of the liquid in the tank, enhancing the anti-evaporation effect. At the same time, the "temporary placement of ice packs" design, combined with the pull-out function of the lever 6, allows for convenient and timely replacement of ice packs to maintain a continuous low temperature environment, flexibly adapting to the liquid storage temperature requirements in different experiments. This, along with the sealing effect of the sealing cap 7 and the sealing block 9, synergizes with the overall anti-evaporation performance of the liquid storage tank.

[0020] like Figure 4 As shown, in some embodiments, the number, size, and shape of the sealing blocks 9 are adapted to the liquid storage tank 2 to seal the liquid storage tank 2. When the sealing cover 7 is closed on the top of the housing 1, each sealing block 9 can be precisely embedded in a liquid storage tank 2. By tightly fitting with the inner wall of the tank, a physical seal is formed, directly blocking the channel for liquid evaporation. Structurally, this prevents volatile liquid from contacting the outside air, thereby effectively inhibiting liquid evaporation. This adaptability design ensures that each liquid storage tank 2 can be independently and tightly sealed, which not only meets the needs of multiple tanks storing liquid at the same time, but also ensures the reliability of single tank sealing, and is highly consistent with the overall anti-evaporation function.

[0021] like Figure 4 As shown, in some embodiments, four support legs 10 are symmetrically arranged on both sides of the sealing cover 7; The supporting leg 10 is L-shaped; When the liquid in the storage tank 2 needs to be taken out and the sealing cap 7 is removed, the four symmetrically distributed L-shaped support legs 10 can stably support the sealing cap 7 on the experimental table, so that the sealing block 9 under the sealing cap 7 is suspended in the air, avoiding direct contact between the sealing block 9 and the table surface, which may cause contamination or damage. At the same time, the sealing cap 7 is placed stably, which facilitates the subsequent re-closing operation. This is in line with the requirements for taking out and putting in the sealing cap 7 and the cleanliness requirements of the overall experimental operation.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
