Technical Field

[0001] This utility model relates to a constant temperature water bath. Background Technology

[0002] Currently, water baths are common laboratory heating devices used to heat reagents or samples contained in containers at a constant temperature. For example, Chinese patent CN209715156U discloses a constant temperature water bath. However, the size of the water bath orifice in existing water baths is usually fixed and cannot be adjusted. When the container holding the reagent or sample is small, the gap between the water bath orifice and the container will be large. This will cause water in the water bath to escape quickly through the gap, resulting in the need to add water frequently during long-term heating. Adding water will cause fluctuations in water temperature, which will affect the test results. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a constant temperature water bath that can adjust the size of the water bath hole, reduce the gap between the water bath hole and the vessel, slow down the loss of water and thus avoid frequent water addition.

The cover plate is provided with at least one water bath hole communicating with the water tank. The adjusting plate is slidably connected to the cover plate and corresponds one-to-one with the water bath holes. The adjusting plate is used to slide to open the corresponding water bath hole, to slide to partially cover the corresponding water bath hole, and to slide to completely cover the corresponding water bath hole in order to adjust the size of the opening of the water bath hole.

[0005] Further, a specific structure of the adjusting plate is provided, wherein one end of the adjusting plate is provided with a V-shaped groove, and when the adjusting plate slides to partially cover the corresponding water bath hole, at least a portion of the uncovered portion of the water bath hole is located in the V-shaped groove.

[0006] Furthermore, the V-groove has a first groove wall and a second groove wall, wherein the first groove wall is perpendicular to the second groove wall; The water bath hole has a square structure, with two opposite sides of the water bath hole parallel to the first tank wall and the other two opposite sides of the water bath hole parallel to the second tank wall.

[0007] Furthermore, the adjusting plate is slidably attached to the lower surface of the cover plate.

[0008] Furthermore, the lower end of the cover plate is connected to a left guide rail corresponding to the adjustment plate and a right guide rail corresponding to the adjustment plate. A left sliding groove is provided between the left guide rail and the cover plate, and a right sliding groove is provided between the right guide rail and the cover plate. The left side of the adjusting plate is slidably fitted in the corresponding left sliding groove, and the right side of the adjusting plate is slidably fitted in the corresponding right sliding groove.

[0009] Furthermore, the adjusting plate is connected to a boss that protrudes upward and extends into the corresponding water bath hole, and the upper end of the boss protrudes from the upper surface of the cover plate.

[0013] Furthermore, the constant temperature water bath also includes a stirring mechanism, which includes a stirring shaft and a stirring motor; The stirring shaft is rotatably disposed in the water tank and located below the support frame, and stirring blades are provided on the stirring shaft; The stirring motor is connected to the stirring shaft and is used to drive the stirring shaft to rotate.

[0014] After adopting the above technical solution, the container holding the reagent or sample is placed into the water tank through the water bath hole. The hot water in the water tank can then heat the reagent or sample in the container. The adjusting plate is then slid to cover part of the corresponding water bath hole, thereby adjusting the size of the water bath hole. When the adjusting plate is slid to the appropriate position, the size of the water bath hole is adapted to the size of the container. At this time, the gap between the water bath hole and the container is small, which can slow down the rate of water loss from the gap, and thus eliminates the need for frequent water addition during long-term heating.

[0016] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] like Figures 1-6 As shown, a constant temperature water bath includes a water tank 1, a cover plate 2, and at least one adjusting plate 3; The opening of the water tank 1 is set upwards; The cover plate 2 is installed on the upper end of the water tank 1 and covers the opening of the water tank 1. The cover plate 2 is provided with at least one water bath hole 4 that communicates with the water tank 1. The adjusting plate 3 is slidably connected to the cover plate 2 and corresponds one-to-one with the water bath holes 4. The adjusting plate 3 is used to slide to open the corresponding water bath hole 4, to slide to partially cover the corresponding water bath hole 4, and to slide to completely cover the corresponding water bath hole 4 so as to adjust the opening size of the water bath hole 4.

[0018] Specifically, after the container 100 containing reagents or samples is placed into the water tank 1 through the water bath hole 4, the reagents or samples in the container can pass through the hot water heater 12 in the water tank 1. Then, the adjusting plate 3 is slid to cover a portion of the corresponding water bath hole 4, thereby adjusting the size of the water bath hole 4. When the adjusting plate 3 is slid to the appropriate position, the size of the water bath hole 4 is adapted to the size of the container 100. Figure 6As shown, the gap between the water bath hole 4 and the vessel 100 is small at this time, which can slow down the rate at which water is lost from the gap, thus eliminating the need for frequent water addition during long-term heating. In this embodiment, multiple water bath holes 4 can be provided sequentially, and during use, the corresponding adjustment plate 3 can be slid to completely cover and close the water bath hole 4 where no vessel 100 is placed.

[0019] like Figure 1 , 2 As shown in Figures 5 and 6, one end of the adjusting plate 3 is provided with a V-shaped groove 5. When the adjusting plate 3 slides to partially cover the corresponding water bath hole 4, at least a portion of the uncovered portion of the water bath hole 4 is located in the V-shaped groove 5. Specifically, the uncovered portion of the water bath hole 4 is the open portion of the water bath hole 4.

[0020] like Figure 1 , 2 As shown in Figures 5 and 6, the V-shaped groove 5 has a first groove wall 6 and a second groove wall 7, and the first groove wall 6 is perpendicular to the second groove wall 7. The water bath hole 4 has a square structure. Two of the opposite sides of the water bath hole 4 are parallel to the first tank wall 6, and the other two opposite sides of the water bath hole 4 are parallel to the second tank wall 7.

[0021] like Figures 1-6 As shown, the adjusting plate 3 is slidably attached to the lower surface of the cover plate 2; specifically, the lower end of the cover plate 2 is connected to a left guide rail 8 corresponding to the adjusting plate 3 and a right guide rail 9 corresponding to the adjusting plate 3; a left sliding groove is provided between the left guide rail 8 and the cover plate 2, and a right sliding groove is provided between the right guide rail 9 and the cover plate 2. The left side of the adjusting plate 3 is slidably fitted in the corresponding left sliding groove, and the right side of the adjusting plate 3 is slidably fitted in the corresponding right sliding groove.

[0022] like Figure 1 , 2 As shown in Figures 5 and 6, the adjusting plate 3 is connected to a boss 10 that protrudes upward and extends into the corresponding water bath hole 4. The upper end of the boss 10 protrudes from the upper surface of the cover plate 2. Specifically, the boss 10 can be located at the bottom of the V-shaped groove 5, and the adjusting plate 3 can be moved by pushing and pulling the boss 10.

[0023] like Figures 1-3 As shown, the constant temperature water bath may also include a support frame 11, which is installed in the water tank 1 and is used to support the vessel 100 placed in the water tank 1. The vessel 100 is placed into the water tank 1 through the water bath hole 4 and supported by the support frame 11. The support frame 11 is provided with multiple hollow holes. The specific structure of the support frame 11 is the prior art.

[0024] like Figures 2-4 As shown, the constant temperature water bath may also include a heater 12, which is installed in the water tank 1 and located below the support frame 11 and is used to heat the water in the water tank 1.

[0025] Specifically, the constant temperature water bath also includes a controller and a temperature sensor. The temperature sensor is installed in the water tank 1 and is used to detect the water temperature information in the water tank 1. The controller is connected to both the temperature sensor and the heater 12 and is used to control the operation of the heater 12 based on the water temperature information detected by the temperature sensor. Specifically, when the temperature sensor detects that the water temperature in the water tank 1 has reached a set value, the controller controls the heater 12 to stop heating. The controller can adjust the water temperature in the water tank 1. In this embodiment, the controller can be a PLC controller, and the heater 12 can be an electric heating element.

[0026] like Figure 3 , 4 As shown, the constant temperature water bath may also include a stirring mechanism, which may include a stirring shaft 13 and a stirring motor 14; The stirring shaft 13 is rotatably disposed in the water tank 1 and located below the support frame 11, and the stirring shaft 13 is provided with stirring blades 15; The stirring motor 14 is connected to the stirring shaft 13 and is used to drive the stirring shaft 13 to rotate. Specifically, when the stirring shaft 13 rotates, it can drive the water in the water tank 1 to flow, thereby keeping the water temperature in the water tank 1 uniform and avoiding water temperature differences in different areas of the water tank 1. The stirring motor 14 is located on the outside of the water tank 1, and the bottom of the water tank 1 is also provided with a drain pipe. The water tank 1 is installed in the outer casing 16, and the stirring motor 14 is also installed in the outer casing 16.

[0027] In summary, after the container 100 containing reagents or samples is placed into the water tank 1 through the water bath hole 4, the reagents or samples in the container can pass through the hot water heater 12 in the water tank 1. Then, the adjusting plate 3 is slid to cover part of the corresponding water bath hole 4, thereby adjusting the size of the water bath hole 4. When the adjusting plate 3 is slid to the appropriate position, the size of the water bath hole 4 is adapted to the size of the container 100. At this time, the gap between the water bath hole 4 and the container 100 is small, which can slow down the rate of water loss from the gap, so that frequent water addition is not required during long-term heating.
