[0002] A water bath is a commonly used laboratory device, primarily used for constant-temperature heating of experimental samples. Existing water baths have relatively fixed structures, and the positions of the heating elements and placement plates are usually not adjustable. This results in insufficient operational flexibility when handling experimental samples of different sizes or performing various experiments, making it difficult to meet diverse experimental requirements.

[0003] Some devices can meet diverse experimental requirements by changing the height of the placement plate. However, the temperature distribution in the water bath is not uniform, and changing the height of the placement plate will change the height difference between the experimental sample and the heating structure, thus affecting the water bath effect of the experimental sample and reducing experimental efficiency and accuracy.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-4 A water bath includes a pot body 1, a water bath tank 2, a heating structure 3, a placement plate 4, and an adjustment device 5. The pot body 1 forms the main frame of the entire device, providing a mounting base for other components. The pot body 1 can be made of stainless steel. The water bath tank 2 is located inside the pot body 1 and can hold a heating liquid, typically water. The heating structure 3 heats the liquid in the water bath tank 2 to achieve water bath heating of experimental samples. The placement plate 4 can hold experimental samples or containers to ensure their stable placement in the water bath tank 2. The placement plate 4 can be made of stainless steel and has multiple holes to facilitate water flow in the water bath tank 2, improving the uniformity of heating of the experimental samples. The adjustment device 5 can adjust the height of the heating structure 3 and the placement plate 4, improving the flexibility and convenience of experimental operations while maintaining the height difference between the experimental samples and the heating structure 3, thereby ensuring the water bath effect of the experimental samples and thus ensuring experimental efficiency and accuracy. The pot body 1 is equipped with a lid with multiple placement holes, which is existing technology and will not be described in detail here.

[0019] The adjustment device 5 includes an adjustment groove 51, a lifting frame 52, and an adjustment component 53. The adjustment groove 51 is located on one side of the water bath 2 and provides space and guidance for the sliding of the lifting frame 52 and the installation of the adjustment component 53. The lifting frame 52 is slidably located in the water bath 2 and is provided with a heating structure 3 and a placement plate 4. The adjustment component 53 is located between the lifting frame 52 and the pot body 1 and can realize the adjustment of the height of the lifting frame 52 in the water bath 2.

[0020] In some embodiments, the adjustment assembly 53 includes an adjustment screw 531 and an adjustment handle 532. The bottom of the adjustment screw 531 passes through the lifting frame 52 and is rotatably connected to the bottom of the adjustment groove 51. This rotatable connection can be achieved through a bearing to ensure that the adjustment screw 531 can rotate flexibly. The adjustment screw 531 is screwed into the lifting frame 52. The top of the adjustment screw 531 passes through the top of the pot body 1. The adjustment handle 532 is coaxially located on the top of the adjustment screw 531 and can be connected by a key or fixed with screws to ensure that the adjustment handle 532 rotates synchronously with the adjustment screw 531. By rotating the adjustment handle 532, the adjustment screw 531 is driven to rotate. Since the adjustment screw 531 is screwed into the lifting frame 52, and the lifting frame 52 can only slide up and down due to the restriction of the water bath 2 and the adjustment groove 51, the height of the lifting frame 52 can be adjusted. The adjustment handle 532 can be made of engineering plastic with a non-slip surface treatment for easy gripping and rotation by the operator.

[0021] In some embodiments, a controller 6 is also included. The controller 6 is located at one end of the pot body 1 and is electrically connected to the heating structure 3. The controller 6 can control the heating temperature and time of the heating structure 3 to achieve precise temperature adjustment. This is prior art and will not be described in detail here.

[0022] In some embodiments, the heating structure 3 includes an electrical connection module 31 and a heating tube 32. The electrical connection module 31 is electrically connected to the controller 6 and is located on one side of the lifting frame 52. The heating tube 32 and the controller 6 can be electrically connected through wires to transmit electrical energy and control signals. Both ends of the heating tube 32 are connected to the electrical connection module 31 to realize the heating structure 3 to heat the liquid in the water bath 2. The heating tube 32 can be made of stainless steel shell and filled with high-temperature magnesium oxide powder as insulating and heat-conducting material. The heating wire can be made of nickel-chromium alloy.

[0023] In some embodiments, the heating tube 32 can be double S-shaped, which can increase the heating area of ​​the heating tube 32, making the heating more uniform and improving the heating efficiency.

[0024] In some embodiments, the lifting frame 52 includes a lifting block 521 and two connecting rods 522. The lifting block 521 is slidably disposed in the adjustment groove 51 to ensure the stability of the lifting frame 52 during the adjustment process. The two connecting rods 522 are vertically disposed on the lifting block 521, and an electrical connection module 31 is provided at one end of the two connecting rods 522 away from the lifting block 521, which can be fixed by bolts. A heating tube 32 is provided parallel between the two connecting rods 522, and a placement plate 4 is provided on the two connecting rods 522. The lifting block 521 slides in the adjustment groove 51, driving the connecting rods 522 and the placement plate 4 to move up and down, so as to realize the synchronous lifting of the heating structure 3 and the placement plate 4, thereby maintaining the height between the experimental sample and the heating structure 3.

[0025] In some embodiments, the placement plate 4 has a groove-shaped cross-section and is secured to the two connecting rods 522 by its two sides, which can improve the stability of the placement plate 4 on the lifting frame 52, thereby improving the stability of the experimental sample water bath process.

[0026] In some embodiments, a drain outlet 7 is also included. The drain outlet 7 is located on one side of the pot body 1 and communicates with the water bath 2. The drain outlet 7 is provided with a drain valve to facilitate the drainage of water from the water bath 2 after the water bath.

[0027] In some embodiments, the inner wall of the water bath 2 is provided with scale lines to indicate the height of the placement plate 4, so that the user can accurately adjust the height of the placement plate 4.

[0028] The specific working principle is as follows: When a water bath is required for the experimental samples, the height of the placement plate 4 and the heating tube 32 is adjusted according to the height of the sample to be bathed. The operator rotates the adjusting handle 532, which drives the adjusting screw 531 to rotate. Since the adjusting screw 531 is screwed into the lifting frame 52, and the bottom of the adjusting screw 531 is rotatably connected to the bottom of the adjusting groove 51, according to the principle of threaded transmission, the rotation of the adjusting screw 531 is converted into the up-and-down sliding of the lifting frame 52 within the adjusting groove 51. The lifting of the lifting frame 52 drives the connecting rod 522, the placement plate 4, and the heating tube 32 to rise and fall synchronously, thereby achieving precise adjustment of the height of the placement plate 4 and the heating tube 32 within the water bath 2 according to experimental needs, meeting the requirements of different experiments for container immersion depth and heating position.

[0029] Water is poured into the water bath 2 to a suitable height. The experimental sample is placed on the placement plate 4, and the lid is closed to secure the sample. After the operator sets the target temperature on the controller 6, the controller 6 controls the working status of the heating tube 32 through the electrical connection module 31. When the temperature reaches the target temperature, the controller 6 reduces the heating power of the heating tube 32 or stops heating; when the temperature is lower than the target temperature, the controller 6 increases the heating power of the heating tube 32. Through this closed-loop control method, precise temperature control is achieved in the water bath 2. After the water bath is complete, the experimental sample is removed. After the liquid in the water bath 2 has cooled, the drain valve is opened to drain the water from the water bath 2 through the drain port 7. The water bath is then cleaned to keep the equipment clean and tidy for future use. The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
