Description

Technical Field

[0001] This utility model relates to the field of water bath technology, and in particular to a laboratory water bath with multiple temperature zones and magnetic stirring capability. Background Technology

[0002] Among numerous laboratory experiments, water bath heating is a common and important heating method. Water baths are widely used in medical testing, scientific research, and daily life. Especially in biochemical and medical laboratories, strict temperature control is required during experiments to ensure accurate and reliable results. Therefore, laboratory water baths are not only used for distillation, drying, concentration, and warm soaking of chemicals or biological products, but also for constant temperature heating and other temperature experiments. They are essential tools for biology, genetics, virology, aquaculture, environmental protection, medicine, health, testing laboratories, analytical laboratories, and educational research.

[0003] Currently, traditional laboratory water baths typically only provide a single temperature environment, failing to meet the needs of multiple different temperature conditions within the same experimental process. For example, some biochemical experiments may require simultaneous heating of different samples at different temperatures to study the effect of temperature on the reaction. This necessitates multiple sample changes or the use of multiple water baths, which is cumbersome and space-consuming. Furthermore, in experiments requiring homogeneous mixing, traditional laboratory water baths lack stirring capabilities. This not only results in uneven water bath temperatures but also necessitates manual stirring by researchers, increasing workload and compromising the uniformity and stability of the mixing process, thus affecting the accuracy and reproducibility of experimental results. Utility Model Content

[0004] To address the technical problems of existing laboratory water baths, which can only provide a single temperature environment and cannot meet the needs of multiple different temperature conditions in the same experiment, and which do not have a stirring function, this utility model provides the following technical solution.

[0005] This utility model discloses a multi-temperature zone magnetically stirred laboratory water bath, comprising a box body equipped with a control panel. The box body is divided into several water bath temperature zones by several partitions. A water bath pot is provided in the upper part of the inner cavity of each water bath temperature zone, and a bracket with a drive motor is fixedly connected to the lower part of the water bath temperature zone. The output end of the drive motor is connected to a magnetic stirrer facing the water bath pot. The water bath pot includes a bottom plate located above the magnetic stirrer and several heating rods located in the upper part of the bottom plate. A support mesh plate connected to the inner wall of the water bath pot is provided above the heating rods. A pot lid is closed on the upper end of the water bath pot, and a sample operation cover plate is rotatably connected to the pot lid.

[0006] As a further technical solution, the pot lid is provided with a sample operation hole and a fixed shaft located on one side of the sample operation hole, and the fixed shaft is rotatably connected to the sample operation cover plate.

[0007] As a further technical solution, a limiting block is fixedly provided on one side of the sample operation hole, and the sample operation cover plate is provided with a protrusion that engages with the limiting block.

[0008] As a further technical solution, the limiting block includes a concave surface that matches the protrusion, as well as rounded corner edges and stop edges located on both sides of the concave surface.

[0009] As a further technical solution, each of the heating rods is heated independently.

[0010] As a further technical solution, both the bottom plate of the pot and the supporting mesh plate are made of paramagnetic or diamagnetic materials.

[0011] The beneficial effects of this invention are as follows: The inner cavity of the chamber is divided into multiple independent water bath temperature zones by partitions. Each water bath temperature zone is equipped with an independent heating rod, temperature sensor, and temperature controller, enabling multiple different water bath temperature environments to meet the needs of various experiments for different temperature conditions and improving experimental efficiency. Each water bath temperature zone has a magnetic stirrer at the bottom, which can stir the liquid and sample in the water bath, ensuring the uniformity and stability of liquid mixing, avoiding errors caused by manual stirring, and improving the accuracy and repeatability of experimental results. Simultaneously, each lid has a sample operation hole, which is covered by a sample operation cover plate. Even with the lid covering the water bath for insulation, simply opening the sample operation cover plate allows for sample operation without affecting the insulation effect inside the water bath, effectively preventing heat loss and ensuring the water bath heating effect.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0014] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] like Figure 1 As shown, this utility model discloses a multi-temperature zone magnetically stirred laboratory water bath, comprising a housing 1 with a control panel 101, the housing 1 being made of stainless steel. The housing 1 is divided into four water bath temperature zones 2 by two partitions 102, each water bath temperature zone 2 being made of heat-insulating material and filled with thermal insulation material. The control panel 101 contains a temperature controller for individually controlling the temperature within each water bath temperature zone 2. Of course, the number of water bath temperature zones 2 is not limited to four; it can be other numbers, and this utility model does not impose any particular limitation on it.

[0016] like Figure 4As shown, in a preferred embodiment, a water bath 3 is provided in the upper part of the inner cavity of the water bath temperature zone 2. Liquid is placed in the water bath 3 for heating, and sample bottles can be placed in it after the water temperature stabilizes. A support 7 is provided in the lower part of the water bath temperature zone 2 below the water bath 3. A drive motor 8 is fixedly connected to the support 7. The output end of the drive motor 8 passes upward through the support 7 and is connected to a magnetic stirrer 9, which is positioned facing the water bath 3. When the magnetic stir bar is placed in the water bath 3, the magnetic stirrer 9 can drive the stirring bar to rotate in the water bath 3 through magnetic force, thereby agitating the liquid in the water bath 3. At the same time, after the sample bottle is placed in the water bath 3, the magnetic stir bar can also be placed in the sample bottle to agitate the sample in the sample bottle.

[0017] In a preferred embodiment, the water bath 3 includes a bottom plate 301 located above the magnetic stirrer 9 and several heating rods 6 located on the upper part of the bottom plate 301. A temperature sensor is installed inside the water bath 3 and connected to a temperature controller built into the control panel 101 for temperature control of each water bath 3. Multiple heating rods 6 are provided, each heating independently. When the temperature inside the water bath 3 differs significantly from the desired water bath temperature, multiple heating rods 6 heat simultaneously, facilitating a rapid temperature rise within the water bath 3. When the temperature inside the water bath 3 is close to the desired water bath temperature, only one heating rod 6 is needed to accurately heat the water to the desired temperature, ensuring the accuracy of the heating process. A support mesh plate 302 connected to the inner wall of the water bath 3 is provided above the heating rods 6. The support mesh plate 302 is used to place sample bottles and prevent direct contact between the sample bottles and the heating rods 6.

[0018] Both the bottom plate 301 and the support mesh plate 302 are made of paramagnetic or diamagnetic materials, so as not to affect the magnetic force of the magnetic stirrer and the magnetic stir bar.

[0019] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a lid 4 covers the upper end of the water bath 3, reducing heat loss within the water bath 3. Each lid 4 is also equipped with a sample operation hole 401. After a sample bottle is placed inside the water bath 3, operations such as adding liquid to the sample bottle can be performed through the sample operation hole 401. At this time, a sample operation cover plate 5 covers the upper part of the sample operation hole 401. The sample operation cover plate 5 is rotatably connected to the lid 4, and rotating the sample operation cover plate 5 opens or closes the sample operation hole 401. With the lid 4 covering and insulating the water bath 3, simply opening the sample operation cover plate 5 allows for sample manipulation without affecting the heat preservation effect within the water bath 3, effectively preventing heat loss and ensuring the heating effect of the water bath.

[0020] In a preferred embodiment, a fixed shaft 402 is provided on one side of the sample operation hole 401, and the fixed shaft 402 is rotatably connected to the sample operation cover plate 5. At this time, a limiting block 403 is fixedly provided on one side of the sample operation hole 401, the sample operation cover plate 5 is provided with a protrusion 501 that engages with the limiting block 403, and a handle 502 is provided on the upper part of the sample operation cover plate 5. The sample operation cover plate 5 can be rotated through the handle 502, and the pot lid 4 can be lifted through the handle 502. In this embodiment, the pot lid 4 is made of corrosion-resistant stainless steel, and the limiting block 403 is made of plastic elastomer. The limiting block 403 includes a concave surface 404 that matches the protrusion 501. The protrusion 501 can elastically engage in the concave surface 404. At the same time, rounded edges 405 and stop edges 406 are provided on both sides of the concave surface 404, respectively. The protrusion 501 can enter and exit the concave surface 404 from the rounded edges 405, and the stop edges 406 are used to prevent the protrusion 501 from moving in that direction.

[0021] When the protrusion 501 is inserted into the concave surface 404, the sample operation cover 5 and the pot lid 4 are as one unit, and the pot lid 4 can be lifted by the handle 502. When the protrusion 501 leaves the concave surface 404 from the rounded corner 405, the sample operation cover 5 rotates and the sample operation hole 401 is opened. At this time, the experimenter can perform operations such as adding liquid to the sample bottle in the water bath 3. After adding liquid, rotate the sample operation cover 5 so that the protrusion 501 is elastically inserted into the concave surface 404, so that the sample operation cover 5 can close the sample operation hole 401.

[0022] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
