Description

Technical Field

[0001] This utility model mainly relates to the field of water bath technology, specifically to a water bath that prevents shaking. Background Technology

[0002] Water baths are widely used laboratory equipment, primarily for heating substances within experimental containers. However, in actual operation, factors such as liquid convection due to heating, external contact, or movement often cause sloshing of the liquid medium. This can not only cause samples to splash out of the experimental container but also affect the accuracy of experimental results. To address this problem, existing water baths typically employ simple anti-sloshing measures, such as increasing sidewall thickness or installing fixed baffles at the bottom. However, these methods have limited effectiveness and cannot effectively suppress liquid fluctuations caused by the aforementioned reasons. Therefore, designing a water bath that can efficiently prevent liquid sloshing has become an urgent technical challenge. Utility Model Content

[0003] 1. The technical problem to be solved by the utility model: This invention provides a water bath that prevents shaking, thereby solving the technical problems existing in the background art.

[0004] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a water bath to prevent sloshing, comprising an outer pot body and an inner pot body arranged coaxially, with a heat insulation layer between the outer pot body and the inner pot body, a heating rod installed inside the inner pot body for heating the liquid medium therein, a shelf for placing experimental containers inside the inner pot body, a lid detachably provided on the upper part of the inner pot body, and a damping plate fixedly provided on the bottom wall of the inner pot body, the damping plate being used to suppress liquid sloshing caused by heating convection, external contact, or movement.

[0005] Preferably, the placement rack includes an annular mounting ring, a placement net located at the center of the mounting ring, and multiple vertically arranged support legs. The lower ends of the support legs are placed on the bottom wall of the inner pot body, and the upper ends are fixedly connected to the mounting ring. The placement net is fixed to the inner side of the mounting ring and is used to support the experimental container.

[0006] Preferably, the heating rod is electrically connected to the controller via a wire. The controller is also connected to a temperature sensor, which is used to monitor the temperature of the liquid in the inner pot in real time and feed the signal back to the controller. The controller then adjusts the start / stop or power of the heating rod to maintain a constant temperature.

[0007] Preferably, the placement rack is further provided with several limiting rings with different inner diameters. The limiting rings are set on the surface of the placement net, and their inner diameters are adapted to the outer diameters of experimental containers of different specifications, for positioning and limiting the experimental containers.

[0008] Preferably, the damping plate includes several horizontal plates, and a first vertical plate is provided on one side of the horizontal plates. The first vertical plate extends along the radial direction of the inner pot body. With the first vertical plate as the center, a second vertical plate, a third vertical plate, and a fourth vertical plate are symmetrically distributed on both sides. The second vertical plate is adjacent to the first vertical plate, the third vertical plate is located outside the second vertical plate, and the fourth vertical plate is located on the outermost side. The length direction of each vertical plate is perpendicular to the length direction of the horizontal plate. The several horizontal plates, the first vertical plate, the second vertical plate, the third vertical plate, and the fourth vertical plate form a multi-level diversion channel.

[0009] Preferably, the other side of the horizontal plate is also provided with several corrugated plates, which are in a continuous wave shape and are used to generate eddy current resistance during liquid flow. Together with the multi-stage diversion channel at the top, they effectively dissipate the liquid kinetic energy caused by heating convection or external disturbances and suppress the sloshing and vibration transmission of the liquid in the inner pot.

[0010] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention effectively suppresses liquid sloshing caused by heating convection, external contact, or movement by incorporating a damping plate on the bottom wall of the inner pot and a multi-stage flow distribution channel combined with a corrugated plate. This significantly improves the stability of the water bath process and avoids safety hazards such as liquid spillage or container tipping. Secondly, the damping plate employs a structure with a second, third, and fourth vertical plate symmetrically distributed on both sides of the first vertical plate, forming a symmetrical and multi-layered flow channel layout. This not only enhances the guidance and dispersion of water flow but also improves energy dissipation efficiency, effectively attenuating the liquid's kinetic energy in a short time. Furthermore, the corrugated plate on the lower side of the horizontal plate is continuously wave-shaped, generating eddy current resistance during liquid flow. This, combined with the multi-stage flow distribution channel above, creates a composite damping effect, further strengthening the anti-sloshing performance. In addition, the placement rack is stably supported at the bottom of the inner pot by support feet, and its limiting ring can accommodate various sizes of experimental containers, achieving precise positioning and anti-slip fixation. Combined with the sealed lid, this also reduces heat loss and steam disturbance. The overall structure achieves efficient anti-sway without the need for a complex control system. It has low manufacturing costs, is easy to maintain, and is suitable for various laboratory constant temperature water bath scenarios. It has good practical value and promotion prospects.

[0018] See attached document Figures 1-7 A water bath designed to prevent sloshing includes an outer pot body 1 and an inner pot body 2 arranged coaxially, with a heat insulation layer between the outer pot body 1 and the inner pot body 2; a heating rod 5 is installed inside the inner pot body 2 for heating the liquid medium therein; a shelf 3 for placing experimental containers is provided inside the inner pot body 2; a lid 4 is detachably provided on the upper part of the inner pot body 2; a damping plate 6 is fixedly provided on the bottom wall of the inner pot body 2, and the damping plate 6 is used to suppress liquid sloshing caused by heating convection, external contact, or movement.

[0019] The placement rack 3 includes an annular mounting ring 31, a placement net 32 ​​located at the center of the mounting ring 31, and multiple vertically arranged support legs 33; the lower end of the support leg 33 is placed on the bottom wall of the inner pot body 2, and the upper end is fixedly connected to the mounting ring 31. The placement net 32 ​​is fixed to the inside of the mounting ring 31 and is used to support the experimental container.

[0020] The heating rod 5 is electrically connected to the controller 7 via a wire. The controller 7 is also connected to a temperature sensor 9, which is used to monitor the temperature of the liquid in the inner pot 2 in real time and feed the signal back to the controller 7. The controller 7 then adjusts the start / stop or power of the heating rod 5 to maintain a constant temperature.

[0021] The placement rack 3 is also equipped with several limiting rings 8 with different inner diameters. The limiting rings 8 are set on the upper surface of the placement net 32, and their inner diameters are adapted to the outer diameters of experimental containers of different specifications, which are used to position and limit the experimental containers.

[0022] The damping plate 6 includes several horizontal plates 61. A first vertical plate 62 is provided on one side of the horizontal plate 61. The first vertical plate 62 extends along the radial direction of the inner pot body 2. With the first vertical plate 62 as the center, a second vertical plate 63, a third vertical plate 64 and a fourth vertical plate 65 are symmetrically distributed on both sides of it. The second vertical plate 63 is adjacent to the first vertical plate 62, the third vertical plate 64 is located outside the second vertical plate 63, and the fourth vertical plate 65 is located on the outermost side. The length direction of each vertical plate is perpendicular to the length direction of the horizontal plate 61. The several horizontal plates 61, the first vertical plate 62, the second vertical plate 63, the third vertical plate 64 and the fourth vertical plate 65 form a multi-level flow distribution channel.

[0023] On the other side of the horizontal plate 61, there are also several corrugated plates 66. The corrugated plates 66 are in a continuous wave shape and are used to generate eddy current resistance during the liquid flow process. Together with the multi-stage diversion channel at the top, they effectively dissipate the liquid kinetic energy caused by heating convection or external disturbance and suppress the sloshing and vibration transmission of the liquid in the inner pot 2.

[0024] Working principle: Once the device is powered on, the heating rod 5 begins to heat the liquid medium in the inner pot 2. As the temperature rises, natural convection occurs within the liquid due to the temperature difference. Without a damping structure, this convection can easily form large-scale eddies, causing violent fluctuations in the liquid surface. At this point, the damping plate 6, located on the bottom wall of the inner pot 2, plays a crucial role.

[0025] The damping plate 6 is supported by a base of several horizontal plates 61. A first vertical plate 62 extending radially along the inner pot body 2 is located on one side of each horizontal plate 61. With the first vertical plate 62 as the center of symmetry, a second vertical plate 63, a third vertical plate 64, and a fourth vertical plate 65 are symmetrically arranged on both sides. These vertical plates are all perpendicular to the length of the horizontal plates 61, collectively forming multiple interconnected but tortuous multi-stage flow channels. When liquid flows into the damping plate 6 region due to convection or external disturbance, it is first blocked and divided into multiple thin streams by the horizontal plates 61, which then enter different flow channels. Due to the symmetrical and staggered arrangement of the channels, the direction of liquid flow is repeatedly changed, the flow velocity is reduced, and the kinetic energy is gradually consumed, thereby effectively suppressing the overall swaying amplitude.

[0026] Meanwhile, on the other side of the horizontal plate 61, there are several corrugated plates 66, which have a continuous wave-like structure. When the liquid flows under the damping plate 6, the undulating surface of the corrugated plates 66 induces local eddies and turbulence, forming continuous fluid resistance and further dissipating the liquid's kinetic energy. The composite damping mechanism of upper multi-stage flow splitting and lower corrugated turbulence achieves three-dimensional and multi-layered suppression of liquid sloshing.

[0027] During the experiment, the user places the experimental container on the placement rack 3, with its bottom supported by the placement net 32 ​​and its outer wall fixed by the limiting ring 8. The support feet 33 ensure that the entire placement rack 3 stands stably against the bottom wall of the inner pot 2. During the heating process, the temperature sensor 9 monitors the liquid temperature in real time and feeds the signal back to the controller 7. The controller 7 adjusts the working state of the heating rod 5 accordingly to maintain a constant temperature. Throughout the entire process of temperature control and disturbance, the damping plate 6 continuously functions to ensure that the liquid inside the inner pot 2 remains stable, preventing the experimental container from shifting or tipping over, thereby ensuring the safety and repeatability of the experiment.

[0028] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
