Description

Technical Field

[0001] This utility model belongs to the field of testing and inspection technology, and in particular relates to an ice-water bath constant temperature oscillation device. Background Technology

[0002] Ice-water baths are a commonly used low-temperature cooling technique that provides and maintains a low-temperature environment by adjusting the cooling water. This technique is typically suitable for various biochemical reactions and experimental procedures conducted below room temperature, especially exothermic reactions or those involving thermally unstable intermediates or final products, such as pesticide residue detection in soil and analysis of microorganisms and sweeteners in food. In existing techniques, ice is often added to maintain the low-temperature environment when conducting ice-water bath shaking experiments using a water bath shaker. However, this process has several drawbacks. First, because ice is less dense than water, it floats on the surface, resulting in an uneven temperature distribution in the ice-water mixture, making it difficult to ensure a constant and uniform low-temperature environment. Second, during shaking, the reciprocating shaking rack collides with the experimental container and the ice, generating noise and potentially causing the container to break or be damaged. Furthermore, as the ice melts, the water level rises, forcing the experimenter to periodically drain the water and add new ice, disrupting the experimental process and increasing operational complexity. In addition, adding ice usually requires stopping the equipment, which affects the continuous oscillation of the sample and further impacts the experimental results.

[0003] Therefore, how to provide a device that can provide a constant and uniform low-temperature water bath environment, continuous and uninterrupted oscillation, avoid damage to the experimental container from collision with the coolant, and prevent the coolant from melting and causing the water bath level to rise is a technical problem that urgently needs to be solved in this field.

[0005] A water bath is used to store cooling water;

[0006] Oscillation assembly, used for oscillation experimental containers;

[0007] The heat transfer trough has one end penetrating through the side wall of the box and the other end being sealed to the side wall of the water bath.

[0008] The cooling components, which can be pulled out, are installed in the heat transfer tank and store coolant inside.

[0009] Furthermore, the cooling assembly includes: a coolant reservoir and a pull-out plate disposed on the outer side of the first end of the heat transfer tank;

[0010] The coolant reservoir is slidably installed inside the heat transfer tank.

[0011] Furthermore, the cooling assembly also includes: a drain outlet, a water collection pipe, and a drain pipe;

[0012] The drain outlet is located at the bottom of the coolant reservoir near the pull-out plate.

[0013] The water collection pipe is located at the armpit corner where the pull-out plate connects to the coolant reservoir and is connected to the drain outlet.

[0014] The drain pipe has one end connected to the water collection pipe through a pull-out plate, and the other end is connected to the outside.

[0015] Furthermore, the upper surface of the bottom plate of the coolant reservoir is inclined, with the lower end located on the drain outlet side.

[0016] Furthermore, the side wall of the cabinet is provided with a pull-out groove, and the pull-out plate can be sealed and closed in the pull-out groove;

[0017] A rubber sealing gasket is provided on the contact surface between the pull-out plate and the inner wall of the pull-out groove.

[0018] Furthermore, the cooling assembly also includes: multiple heat transfer plates that are ringed around the outer wall of the heat transfer groove, with the heat transfer plates spaced apart along the length of the heat transfer groove.

[0019] Furthermore, it also includes: a first magnetic element disposed on the pull-out plate and a second magnetic element disposed correspondingly in the pull-out groove.

[0020] Furthermore, the oscillation assembly includes: an oscillation frame disposed above the heat transfer tank and an oscillation drive disposed at the bottom of the housing;

[0021] The oscillation drive is connected to the oscillation frame and drives the oscillation frame to oscillate back and forth in the water bath.

[0022] Furthermore, the ice-water bath constant temperature oscillation device also includes: a temperature sensor installed in the water bath and an electric heating tube installed at the bottom of the water bath;

[0023] Temperature sensor connected to electric heating element.

[0024] Furthermore, the top of the box has an opening and is equipped with an openable sealing cover.

[0025] In this embodiment, a water bath constant-temperature oscillation device is provided. In use, water is first poured into the water bath, ensuring the water level exceeds the top of the oscillation frame and completely covers the bottom of the heat transfer tank and the experimental container. The water in the water bath serves as the temperature conduction medium, preparing for a low-temperature state. A cooling component is slid into the heat transfer tank via a pull-out mechanism. The cooling component contains a coolant (such as ice, an ice-water mixture, or dry ice). Once pulled into place, the coolant begins to contact the heat transfer tank. The coolant absorbs heat from the water in the water bath, rapidly lowering the water bath temperature to a predetermined low-temperature range (e.g., 2-8°C), forming an effective heat exchange with the water in the water bath through the heat transfer tank. Because the coolant exchanges heat with the water in the water bath through the heat transfer tank, the water temperature in the water bath is continuously maintained within the predetermined temperature range. At this point, the oscillation component begins to operate, oscillating the experimental container within the water bath. The sample in the experimental container can be kept at a constant temperature. Simultaneously, the oscillation process promotes uniform mixing of reactants, improves reaction efficiency, and also promotes the flow of cooling water in the water bath, ensuring a uniform temperature of the cooling water. During the experiment, the coolant gradually absorbs heat and melts. At this point, by pulling out the cooling components in the heat transfer tank, the operator can quickly replace the coolant without stopping the machine, thus maintaining a stable low-temperature environment. The melted coolant can be discharged by pouring or other means, ensuring that the water level does not rise due to coolant melting. Because the coolant does not directly collide with the reaction container, damage to the device due to collision is avoided, and noise during the oscillation process is reduced. In summary, this invention provides an ice-water bath constant-temperature oscillation device that provides a constant and uniform low-temperature water bath environment, continuous and uninterrupted oscillation, avoids damage to the experimental container due to collision with the coolant, and prevents the water bath level from rising due to coolant melting.

Those skilled in the art will understand that anything that does not violate the essential points of the utility model within the scope of its inventive concept should be included within the protection scope of this utility model.

[0035] This utility model provides an ice-water bath constant temperature oscillation device, for reference... Figure 1-3 It includes: a cooling assembly 1, a housing 2, a water bath 3 set on the top of the housing 2, a heat transfer tank 4 set at the bottom of the water bath, and an oscillation assembly 5 set above the heat transfer tank 4;

[0036] Water bath 3 is used to store cooling water;

[0037] Oscillating component 5 is used for oscillating experimental container 7;

[0038] The heat transfer tank 4 has its first end penetrating through the side wall of the box 2, and its second end being sealed to the side wall of the water bath 3.

[0039] Cooling component 1 is a pull-out component installed in heat transfer tank 4, which contains solid coolant.

[0040] In this embodiment, a water bath constant-temperature oscillation device is provided. During use, cooling water is first injected into the water bath, ensuring the water level exceeds the top of the oscillation frame and completely covers the bottom of the heat transfer tank. At this point, the cooling water in the water bath serves as a temperature conduction medium, preparing for a low-temperature state. The cooling component is slid into the heat transfer tank via a pull-out mechanism. The cooling component contains a solid coolant (such as ice, an ice-water mixture, or dry ice). Once the cooling component is pulled into place, the coolant begins to contact the heat transfer tank. The solid coolant absorbs heat from the water in the water bath, rapidly lowering the temperature of the water bath to a predetermined low-temperature range (e.g., 2-8°C). Effective heat exchange occurs between the solid coolant and the cooling water in the water bath through the heat transfer tank. Due to the heat exchange between the solid coolant and the water in the water bath through the heat transfer tank, the temperature of the cooling water in the water bath is continuously and constantly maintained within the predetermined temperature range. At this point, the oscillation component begins operation, vibrating the experimental container within the water bath. This vibration promotes uniform mixing of the reactants, improving reaction efficiency, and also facilitates the flow of cooling water within the water bath, ensuring a more uniform temperature. During the experiment, the solid coolant gradually absorbs heat and melts into a liquid state. By pulling out the cooling component within the heat transfer tank, operators can quickly replace the solid coolant without shutting down the system, maintaining a stable low-temperature environment and ensuring uninterrupted experimental procedures. The melted liquid coolant is drained by pouring or other means, ensuring the cooling water level does not rise due to the melting of the solid coolant. Because the solid coolant does not directly contact the reaction container, damage from impacts is avoided, and noise during oscillation is reduced. More preferably, [reference needed]. Figure 2-4 Multiple heat transfer tanks are spaced 4 times apart at the same height, and cooling components are correspondingly installed within the heat transfer tanks. Heat dissipation is achieved through the combination of multiple heat transfer tanks and cooling components, further improving heat exchange efficiency and the temperature uniformity of the cooling water in the water bath. Specifically, the number of heat transfer tanks is 4-7. In summary, this invention provides an ice-water bath constant-temperature oscillation device that provides a constant and uniform low-temperature water bath environment, continuous and uninterrupted oscillation, avoids damage to the experimental container from collision with the coolant, and prevents the coolant from melting and causing the water bath liquid level to rise.

[0041] Preferred, Reference Figure 4-5 The cooling assembly 1 includes: a coolant reservoir 11 and a pull-out plate 12 disposed on the outer side of the first end of the heat transfer tank 4;

[0042] The coolant container 11 is slidably disposed within the heat transfer tank 4.

[0043] In this embodiment, the coolant container holds solid coolant and can slide within the heat transfer tank, allowing it to be pulled out or pushed in as needed. This facilitates user removal of the coolant container for replacement of the solid coolant. Operators can also adjust the cooling rate of the cooling water in the water bath by adjusting the depth of the coolant container's insertion. Specifically, the solid coolant is ice, and the ice fills 2 / 3 to 3 / 4 of the coolant container's height. A small amount of liquid water can be injected into the coolant container to fill the gaps between the ice blocks, further improving heat transfer efficiency. A pull-out plate, located on the outer side of the first end of the heat transfer tank, assists in the sliding operation of the coolant container. Operators can easily slide the coolant container into or out of the heat transfer tank using the pull-out plate. More preferably, see reference... Figure 3 A handle 13 is provided on the outside of the pull-out plate to further improve the operability of sliding the coolant reservoir.

[0044] Preferred, Reference Figure 5 The cooling assembly 1 also includes: a drain outlet 14, a water collection pipe 15, and a drain pipe 16;

[0045] Drain outlet 14 is located at the bottom of one end of coolant reservoir 11 near pull-out plate 12;

[0046] The water collection pipe 15 is located at the armpit corner where the pull-out plate 12 connects to the coolant reservoir 11, and is connected to the drain outlet 14.

[0047] The drain pipe 16 has one end connected to the water collection pipe 15 through the pull-out plate 12, and the other end is connected to the outside.

[0048] In this embodiment, the drain outlet is located at the bottom of the coolant reservoir near the pull-out plate. When the solid coolant in the coolant reservoir begins to melt or accumulate, the liquid flows into the water collection pipe through the drain outlet. The water collection pipe is located at the junction of the pull-out plate and the coolant reservoir and is connected to the drain outlet. When the liquid in the coolant reservoir flows into the water collection pipe through the drain outlet, the water collection pipe guides the liquid to the drain pipe. The drain pipe passes through the pull-out plate and is connected to the water collection pipe, draining the melted water from the coolant reservoir. The operator does not need to remove the entire coolant reservoir to empty the water. Because the melted coolant can be efficiently discharged through the water collection pipe and drain pipe, the liquid coolant will not overflow the coolant reservoir or accumulate for a long time, affecting the coolant performance and ensuring that the coolant maintains a highly efficient cooling state within the reservoir. More preferably, refer to... Figure 5 The drain pipe is equipped with a drain valve 17. Operators can simply operate the drain valve 17 to remove the liquid coolant, which greatly reduces the difficulty of maintenance.

[0049] More preferably, the upper surface of the bottom plate of the coolant reservoir is inclined, with the lower end located on the drain outlet side, ensuring that the melted coolant flows naturally to the drain outlet due to gravity, reducing the need for manual intervention and simplifying maintenance.

[0050] More preferably, refer to Figure 5 The side wall of the box body 2 is provided with a pull-out groove 21, and the pull-out plate 12 can be sealed and closed in the pull-out groove 21;

[0051] A rubber sealing gasket 18 is provided on the contact surface between the pull-out plate 12 and the inner wall of the pull-out groove 21.

[0052] In this embodiment, a pull-out groove is provided on the side wall of the housing, allowing the pull-out plate to be sealed within it. This effectively reduces the contact between the cooling components and outside air, minimizing heat loss and improving cooling efficiency. The pull-out groove design ensures that the pull-out plate is flush with the housing surface when closed, resulting in a cleaner and more aesthetically pleasing appearance. Furthermore, a rubber sealing gasket is placed at the contact surface between the pull-out plate and the inner wall of the pull-out groove to enhance sealing and prevent hot external air from entering the cooling system. The rubber sealing gasket also provides cushioning, making the pull-out process smoother and preventing shaking or jamming caused by uneven pulling, thus reducing the risk of accidents due to improper operation. More preferably, the pull-out plate is made of heat-insulating rock wool board to further improve the insulation effect and reduce heat loss.

[0053] More preferably, refer to Figure 4 The cooling assembly also includes: multiple heat transfer plates 6 that are ringed around the outer wall of the heat transfer groove 4, and the heat transfer plates 6 are spaced apart along the length of the heat transfer groove 4.

[0054] In this embodiment, heat transfer fins are ringed around the outer wall of the heat transfer tank and spaced apart along its length, which significantly increases the heat dissipation area of ​​the heat transfer tank and enhances the heat exchange efficiency between the coolant and the cooling water in the water bath. Due to the spaced arrangement of the heat transfer fins, they promote more uniform temperature conduction on the outer wall of the heat transfer tank, thereby reducing local temperature differences inside the water bath and making the entire low-temperature water bath environment more stable. More preferably, refer to... Figure 4 The heat transfer fins 6 are spaced equally, further improving the temperature uniformity of the cooling water in the water bath. More preferably, the heat transfer tank, conductive fins, and coolant container are all made of stainless steel to further improve heat exchange efficiency, prevent rusting, and extend the service life of the device.

[0055] More preferably, the cooling assembly further includes: a first magnetic element disposed on the pull-out plate and a second magnetic element disposed correspondingly in the pull-out groove.

[0056] In this embodiment, a first magnetic element is provided on the pull-out plate, and a second magnetic element is correspondingly provided in the pull-out groove. Utilizing magnetic attraction, the pull-out plate can be tightly fitted to the side wall of the housing, further enhancing the sealing effect and effectively reducing the loss of cold energy inside the cooling components. Moreover, the magnetic structure eliminates the need for an additional mechanical locking mechanism, making the overall structure of the device simpler.

[0057] More preferably, refer to Figure 3 The oscillation assembly 5 includes: an oscillation frame 51 disposed above the heat transfer tank and an oscillation drive 52 disposed at the bottom of the housing;

[0058] The oscillation drive 52 is connected to the oscillation frame 51 and drives the oscillation frame 51 to oscillate back and forth in the water bath 3.

[0059] In this embodiment, the oscillation drive mechanism drives the reciprocating motion of the oscillation frame, which promotes convection of water flow within the water bath. This allows the heat absorbed by the cooling components to be transferred more quickly throughout the water bath, preventing localized temperature unevenness and ensuring a more stable temperature within the water bath. Simultaneously, the reciprocating oscillation of the oscillation frame keeps the reactants within the experimental container in a dynamically mixed state, preventing the formation of localized temperature gradients and thus improving the uniformity of sample heating. Specifically, the oscillation drive mechanism is a device or mechanism that provides reciprocating vibration, such as a motor-driven eccentric wheel mechanism, a linkage mechanism, or an electromagnetic drive mechanism, to provide stable and controllable reciprocating oscillation motion.

[0060] Preferably, the ice-water bath constant temperature oscillation device further includes: a temperature sensor disposed in the water bath and an electric heating tube disposed at the bottom of the water bath;

[0061] Temperature sensor connected to electric heating element.

[0062] In this embodiment, a temperature sensor is installed inside the water bath to monitor the water bath temperature in real time. Feedback is used to adjust the operating state of the electric heating element, maintaining the temperature within the water bath within a set range. This allows the device to be used not only for low-temperature experiments but also for heating via the electric heating element, making it suitable for a wider range of experimental applications, such as biological culture, enzyme reactions, food testing, and drug dissolution, which involve different specific temperature conditions. This improves the applicability and flexibility of the device. Notably, the key aspect of this application is providing an ice-water bath constant-temperature oscillation device. Mechanically, this device provides a constant and uniform water bath for the experimental container and reactants at a specific temperature, and provides uninterrupted continuous oscillation. The temperature regulation mode and method can be implemented using a programmable logic device such as a PLC, which will not be elaborated further here.

[0063] More preferably, the top of the box is open and equipped with a sealing cover.

[0064] In this embodiment, the top of the chamber is open and equipped with a sealing cap, which facilitates the placement, removal, and handling of experimental containers and reactants. Furthermore, during the experiment, it prevents dust, impurities, or volatile chemicals from entering the water bath and affecting experimental accuracy. The sealing cap also reduces noise and splashes from the oscillation components, improving experimental safety.

[0065] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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.
