Description

Technical Field

[0001] The utility model belongs to the technical field of chemical testing equipment, in particular to a water bath device. Background Art

[0002] During laboratory disinfectant efficacy validation, the plates containing the disinfectant must be placed in a 20°C water bath. This process, performed in a biosafety cabinet for biosafety reasons, requires a water bath to ensure the plates remain level and the interior of the plates is protected from contamination.

[0003] Because the sample storage container that needs a water bath is relatively thin and it is difficult to control the liquid level in the circulating water bath to be stable, the existing fixed clamps will cause the circulating water to flow into the sample during the water bath or the liquid level to be too low to contact the container, resulting in sample contamination and other phenomena that prevent normal water bathing.

[0004] Related patent document CN214765575U discloses a low-temperature constant temperature bath, in which a plurality of relatively arranged fixed plates are fixed in the bath, and a plurality of pairs of relatively arranged moving blocks are slidably arranged between the fixed plates. The opposite side walls of each pair of moving blocks are fixed with arc-shaped clamping plates, and a driving assembly is provided between the opposite fixed plates to drive the relative moving blocks to move closer to or away from each other and to fix their positions. The driving assembly includes a screw and a guide rod parallel to the screw. The screw is rotatably connected between the two fixed plates. The guide rod is located on one side of the screw and is rotatably connected to the relative fixed plates. The same guide rod passes through the two relative moving blocks. The thread on the screw is divided into two opposite parts from the middle, and the two moving blocks are respectively threadedly connected to different threads. The structure of the fixed test tube is quite complicated and difficult to install. Utility Model Content

The plate fixing plate II2 slides toward the plate fixing plate I1 via the guide rail 10, clamping the plate 33 between the plate fast fixing plates. The plate clamp plate fixing plate assembly 7 can both float on the water surface and fix the plate 33. The water bath sample can change with the change of the water bath liquid level, ensuring that the sample achieves a normal water bath effect.

[0036] The inner wall of the water tray 5 is detachably provided with a temperature sensing probe 31 by means of a threaded connection. The inner wall of the water tray 5 is provided with a threaded connection port, and the temperature sensing probe 31 is fixed to the inner wall of the water tray 5 by means of a threaded connection, so as to facilitate testing the water temperature in the water tray 5.

[0037] In the shell 4, a water inlet 6 is provided on the water pan 5. A heat exchanger, a compressor and an external circulation water pump are provided in the water bath external unit, and the compressor is connected to the heat exchanger through a four-way valve. The external circulation water pump is connected to the water inlet interface on the shell 4 through a hose, and the water inlet interface is connected to the water inlet 6.

The external circulation water pump is then used to supply water to the water bath internal unit (water pan 5 in the shell 4).

[0038] like Figure 3 、 4 As shown, the plate fixing plate I1, plate fixing plate II2, and plate fixing plate III3 are assembled together through a guide rail 10. The fixing member 19 is tightened and fixed to the guide rail 10 behind the side 16, simplifying the structure of the supporting assembly of the plate 33 and facilitating installation. In this embodiment, the fixing member 19 is a bolt.

[0039] South pole magnets I 181 are fixedly arranged on the U-shaped bottom edge and the end of the U-shaped opening 9 of the plate fixing plate I 1. South pole magnets II 182 are fixedly arranged on the U-shaped bottom edge of the plate fixing plate II 2.

[0040] The bottom surface of the left fixing plate 14 is hollow, with a left semicircular recess 22 defined therein. A north pole magnet I 183 is fixedly mounted on the left side 16 opposite the left semicircular recess 22. The bottom surface of the right fixing plate 15 is hollow, with a right semicircular recess 23 defined therein.

This makes assembly and replacement more efficient and labor-saving. The U-shaped ends of plate fixing plates I1 and II2 are magnetically attached, eliminating the need for traditional bolts, nuts, and other tools, resulting in efficient assembly and improved work efficiency.

[0042] like Figure 5As shown, a plate holder 24 is provided on both the left semicircular notch 22 and the right semicircular notch 23 to support the plate 33 and stabilize the plate 33. A magnet can be attached to the plate holder 24 to fix the plate 33 by the suction force of the magnet.

[0043] The plate fixing plate assembly 7 is made of plastic and is placed in the water tray. It floats on the water surface by utilizing its buoyancy and can be taken out of the water to facilitate cleaning of the water tray 5 .

[0044] A fixed baffle 26 is welded to the water pan 5, dividing it into a plate compartment 27 and an overflow compartment 28. An overflow port 29 is defined on baffle 26, and a return port 30 is defined on the bottom of overflow compartment 28. The plate fixing plate assembly 7 floats in the plate compartment 27. When the water level reaches the overflow port 29, it overflows and flows back through the return port 30 and the water outlet 8 into the external water tank.

[0045] like Figure 2 As shown, during the experiment, constant temperature water flows into the water tray 5 from the water inlet 6, and overflow water flows out from the overflow port 29. Place the plate fixing plate assembly 7 into the water tank, pull open the plate fixing plate II2, and place the plate fixing plate of the required specifications. The left fixing plate (14) is magnetically attracted to the plate fixing plate I1, and the right fixing plate 15 is magnetically attracted to the plate fixing plate II2. Push the plate fixing plate II2 toward the plate fixing plate I1, and the two are magnetically attracted together. Place the plate 33 on the plate holder 24, and the experiment can begin.

[0046] like Figure 6 As shown, in another embodiment, the water inlet channel 25 is placed directly in the water tray 5. The water inlet channel 25 uses its own gravity to cover the water inlet 6. The water inlet channel 25 is a square cavity with a hollow bottom. A water outlet channel is excavated in the middle of the square cavity. The water outlet channel is surrounded by four side walls, and a water outlet 32 ​​is provided on one of the side walls. One end of the water inlet channel 25 has a space that can accommodate the size of the water inlet 6. Water passes through the water inlet 6, through the cavity of the water inlet channel 25, and into the water tray 5 through the water outlet 32. When water enters, the water will not rush directly upwards, preventing the flat dish 33 from being washed away, further ensuring that the flat dish 33 does not float around, and improving work efficiency and the accuracy of the test results. The water inlet channel 25 can be taken out of the water tray 5 to facilitate cleaning of the water tray 5.

[0047] like Figure 7 As shown, during the experiment, constant-temperature water flows from the water inlet 6 into the water inlet channel 25, and from the water outlet 32 ​​of the water inlet channel 25 into the water tray 5. Overflow water flows out of the overflow port 29. Place the plate holder assembly 7 into the sink, open the plate holder plate II2, and replace the plate holder plate of the required specifications. The left plate holder 14 is magnetically attached to the plate holder plate I1, and the right plate holder 15 is magnetically attached to the plate holder plate II2. Push the plate holder plate II2 toward the plate holder plate I1, and the two will magnetically close. Place the plate holder plate 33 on the plate holder 24, and the experiment can begin.
