Description

Technical Field

[0001] This application relates to the field of constant temperature equipment, specifically to a water bath device. Background Technology

[0002] Water baths are primarily used in laboratories for distillation, drying, concentration, and warm soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature experiments. They are essential tools for biological, genetic, virological, aquatic, environmental, pharmaceutical, sanitation, laboratory, analytical, and educational research fields. A stainless steel tubular heater is horizontally placed inside the water bath, and perforated aluminum baffles are installed within the water bath chamber. The top plate is equipped with combination rings of different diameters to accommodate flasks of varying sizes. The water bath includes a water outlet pipe and an electrical box. The panel of the electrical box contains temperature control instruments and a power switch. The electrical box also houses heating elements and sensors.

[0003] However, in existing water baths, due to the static state of the water during heating, the water temperature near the heating element is higher, while the water temperature further away from the heating element is lower, resulting in an uneven water temperature distribution within the water bath chamber. This temperature gradient not only affects the accuracy of experimental results but may also adversely affect the samples inside the flask. Monitoring the water temperature within the water bath is also challenging. Specifically, if the sensor detects water near the heating element, the detected temperature will be higher; however, after heat conduction in the water, the actual water temperature inside the water bath chamber will be lower than the sensor's detected temperature. Conversely, if the sensor detects water far from the heating element, when the sensor detects a temperature threshold, after heat conduction in the water, the actual water temperature inside the water bath chamber will be higher than the sensor's detected temperature, resulting in lower sensor accuracy.

[0013] In one embodiment, the circulation pump is also located in the middle of the inner wall of the water bath chamber, and the circulation pump located in the middle of the inner wall of the water bath chamber is set close to the partition.

[0014] This application has at least the following beneficial effects: In this application, multiple circulation pumps are distributed inside the water bath chamber. The circulation pumps drive the movement of clean water in the water bath chamber, so that the water in the water bath chamber flows fully.

[0026] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1-4 As shown, some embodiments of this application provide a water bath device, including: a pot body 11 for loading flasks, the pot body 11 having a water bath chamber 111, the water bath chamber 111 for containing liquid, and loading the flasks into the pot body 11 specifically means placing the flasks in the liquid. The working process of this water bath device is as follows: the liquid exchanges heat with the sample in the flask, so that the sample is kept at a constant temperature. The liquid is preferably clean water, which has a high specific heat capacity (the amount of heat absorbed or released by a unit mass of a substance when its temperature rises or falls by 1 degree Celsius without phase change or chemical change). Clean water can store more heat. Compared with other liquids, clean water can rise in temperature by a lower degree when absorbing the same amount of heat, that is, clean water absorbs or releases more heat when its temperature rises or falls by 1 degree Celsius. Therefore, clean water is easier to regulate in terms of temperature rise and fall, and the water temperature is less likely to fluctuate, so as to achieve constant temperature. A circulation pump (14, 15), a heating module 16, and a temperature sensor 17 are built into the water bath chamber 111. The heating module 16 is located at the bottom of the water bath chamber 111, away from the flask to avoid direct contact and potential overheating that could cause the flask to crack. The heating module 16 heats the water in the water bath chamber 111. At least two temperature sensors 17 are present, circumferentially distributed throughout the water bath chamber 111, detecting the water temperature at different locations within the chamber. A control instrument 112 and a switch 113 are mounted on the outer surface of the pot body 11. The control instrument 112 displays and adjusts the water temperature. The heating module 16 and temperature sensors 17 are electrically connected to the control instrument 112. The switch 113 controls the operation of the control instrument 112 and / or the circulation pumps (14, 15).

[0028] In this design, at least two circulation pumps (14, 15) are installed inside the water bath chamber 111, and multiple circulation pumps (14, 15) are spaced apart within the water bath chamber 111. More specifically, the multiple circulation pumps (14, 15) are respectively located at the bottom and top of the inner wall of the water bath chamber 111. The multiple circulation pumps (14, 15) distributed within the water bath chamber 111 cause the water in the water bath chamber 111 to flow, and due to the cooperation of the multiple circulation pumps (14, 15), the water in the water bath chamber 111 is agitated, so that the water in the water bath chamber 111 is mixed to a uniform temperature. For example, the number of circulation pumps (14, 15) is two, and the distance between the two circulation pumps (14, 15) is the maximum distance within the water bath chamber 111. By having the circulation pumps (14, 15) respectively positioned at the two locations with the maximum distance within the water bath chamber 111, the water in the water bath chamber 111 is allowed to flow sufficiently.

[0029] It is understandable that the maximum spacing within the water bath 111 refers to the two furthest edges of the water bath 111. Movable water flows are formed at these two points of maximum spacing, which can maximize the flow of water throughout the entire water bath 111. The water flow between these two points of maximum spacing agitates the water within the water bath 111, causing rapid mixing of water from different areas (water at different temperatures), thereby quickly achieving a uniform temperature throughout the water bath 111.

[0030] Furthermore, the water bath chamber 111 is a cube. The circulation pumps (14, 15) include a first circulation pump 14 and a second circulation pump 15. The maximum distance within the water bath chamber 111 is specifically the distance between two corresponding diagonals within the water bath chamber 111, where the two diagonals are oblique. Specifically, the first circulation pump 14 and the second circulation pump 15 are respectively installed at two opposite diagonals of the water bath chamber 111. The second circulation pump 15 is installed at the lower left diagonal of the water bath chamber 111, and the first circulation pump 14 is installed at the upper right diagonal of the water bath chamber 111. The diagonal is an interior angle formed by the two side surfaces and the top or bottom surface. The first circulation pump 14 and the second circulation pump 15 are installed on different side surfaces.

[0031] Meanwhile, reference Figure 6As shown, the inlet and outlet directions of the circulation pumps (14, 15) are perpendicular. Specifically, the inlet directions of the first circulation pump 14 and the second circulation pump 15 are parallel and opposite, and the outlet directions of the first circulation pump 14 and the second circulation pump 15 are parallel and opposite. The first circulation pump 14 and the second circulation pump 15 form water flows in opposite directions at the top and bottom of the water bath chamber 111. The water flow formed by the circulation pumps (14, 15) flows along the inner wall of the water bath chamber 111, thereby driving the flow of clean water between the top and bottom of the water bath chamber 111, so as to accelerate the mixing speed of the clean water in the water bath chamber 111, so as to quickly and evenly distribute the heat of the clean water in the water bath chamber 111.

[0032] In another specific embodiment, the water bath chamber 111 is cylindrical. The circulation pumps (14, 15) include a first circulation pump 14 and a second circulation pump 15. The first circulation pump 14 and the second circulation pump 15 are located on the upper and lower edges of the water bath chamber 111, respectively. The edges of the cylindrical water bath chamber 111 can be understood as the edges formed by the intersection of the annular inner wall surface and the bottom or top surface. The distance between the two circulation pumps (14, 15) is the maximum distance within the water bath chamber 111. Specifically, the maximum distance within the water bath chamber 111 means that the first circulation pump 14 and the second circulation pump 15 are located in the same vertical plane, and the central axis of the water bath chamber 111 is also located in this vertical plane, with the line connecting the first circulation pump 14 and the second circulation pump 15 intersecting the central axis of the water bath chamber 111.

[0033] The angle formed between the inlet and outlet directions of the circulation pumps (14, 15) is an obtuse angle. Specifically, the inlet directions of the first circulation pump 14 and the second circulation pump 15 are parallel and opposite, and the outlet directions of the first circulation pump 14 and the second circulation pump 15 are parallel and opposite.

[0034] Furthermore, the temperature sensor 17 is located at the bottom of the water bath chamber 111. In this design, there are at least two temperature sensors 17, which are distributed circumferentially along the bottom edge of the water bath chamber 111. The heating module 16 is located at the center of the bottom of the water bath chamber 111, so that the multiple temperature sensors 17 are distributed circumferentially around the periphery of the heating module 16. By detecting the water temperature through the temperature sensors 17 at multiple locations, it is determined whether the water temperature in the water bath chamber 111 is uniform.

[0035] For example, there are four temperature sensors 17. The four temperature sensors 17 are located at the four opposite corners of the bottom of the water bath chamber 111. However, since the second circulation pump 15 is located at one of the opposite corners of the bottom of the water bath chamber 111, and one of the temperature sensors 17 is positioned close to the second circulation pump 15, the four temperature sensors 17 are positioned close to the four opposite corners of the bottom of the water bath chamber 111. In one specific embodiment, the water temperature detected by the temperature sensors 17 is displayed in real time on the control instrument 112, and the desired temperature can also be set on the control instrument 112.

[0036] In some embodiments of this application, at least three protruding support blocks 114 are provided inside the water bath chamber 111. The support blocks 114 are located on the inner wall of the water bath chamber 111, and multiple support blocks 114 are located on the same horizontal plane. A partition 13 is supported on the support blocks 114, and the partition 13 is located above the heating module 16. Correspondingly, the first circulation pump 14 is located above the partition 13. The water bath chamber 111 is divided into two chambers by the partition 13, and the two chambers are arranged one above the other. The second circulation pump 15, the heating module 16, and the temperature sensor 17 are located in the lower chamber, and the first circulation pump 14 is located in the upper chamber. The partition 13 has water passage holes 131, which allow the exchange of clean water between the top and bottom of the water bath chamber 111, thereby completing the mixing of clean water at different temperatures. The bottom of the flask rests on the partition 13, which isolates the flask from the heating module 16 to prevent the flask from directly contacting the heating module 16 and causing the flask to break.

[0037] In this design, the water passage holes 131 are circular and arranged in an array on the baffle plate 13 to increase the flow rate of water through the baffle plate 13. It is understood that the shape of the water passage holes 131 includes, but is not limited to, circular shapes; they can also be elliptical or elongated. The arrangement of the water passage holes 131 is not limited to an array layout; they can also be staggered or arranged irregularly. Therefore, any implementation method that designs the shape and arrangement of the water passage holes 131 to achieve more efficient clean water exchange should be considered a specific embodiment of this application.

[0038] Furthermore, the circulation pumps (14, 15) also include a third circulation pump (not shown), which is located in the middle of the inner wall of the water bath chamber 111 and is positioned near the partition 13. Preferably, the third circulation pump is located in the lower cavity. Specifically, the third circulation pump is positioned near the partition 13, meaning it is simultaneously attached to the bottom surface of the partition 13 and the inner wall of the water bath chamber 111. In this design, increasing the number of circulation pumps (14, 15) increases the flow rate of the water in the water bath chamber 111, thereby accelerating the mixing speed of the clean water in the water bath chamber 111.

[0039] In some embodiments of this application, such as Figure 4 , 5 As shown, the water bath chamber 111 includes a main chamber 1111 and a skirt 1112. The skirt 1112 is located at the top of the main chamber 1111. The circulation pump (14, 15), heating module 16, and temperature sensor 17 are disposed inside the main chamber 1111. A step portion is formed between the skirt 1112 and the main chamber 1111 to support the top plate 12. The water bath chamber 111 has an inverted step shape, and the outline area of ​​the skirt 1112 is larger than the outline area of ​​the main chamber 1111. The top plate 12 can be installed inside the skirt 1112 and is supported by the step portion formed between the skirt 1112 and the main chamber 1111.

[0040] In this design, the top plate 12 can cover the opening of the water bath chamber 111, making the water bath chamber 111 airtight, reducing heat loss, and concentrating heat energy in the water bath chamber 111 as much as possible, thereby improving the heating efficiency of the water bath device.

[0041] Furthermore, at least two sealing caps 121 are installed on the top plate 12. In this design, the top plate 12 has multiple through holes that connect to the water bath chamber 111, and the sealing caps 121 are positioned corresponding to these through holes. The flask is inserted into the water bath chamber 111 through the through holes. Specifically, the sealing cap 121 includes multiple concentric ring caps and a central cap. The central cap is installed in the hollow portion of the smallest diameter ring cap. Simultaneously, adjacent ring caps are nested within each other; the adjacent ring caps are the first ring cap and the second ring cap. The inner diameter of the first ring cap matches the outer diameter of the second ring cap, allowing the second ring cap to be installed inside the first ring cap. The appropriate ring cap is removed according to the ring diameter of the flask to expose a through hole of the corresponding diameter, facilitating the insertion of the flask. The ring diameter is the diameter at the maximum profile of the flask.

[0042] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
