Description

Technical Field

[0001] This utility model relates to the field of water bath technology, specifically to an electric thermostatic water bath. Background Technology

[0002] A constant-temperature water bath is an indispensable precision temperature control device in the laboratory. Its core function is to transfer heat through water, providing a continuous and stable temperature environment for the experimental process. This equipment is widely used in chemical synthesis, biological culture, and pharmaceutical preparation, and is particularly suitable for sample processing that is sensitive to temperature fluctuations. Structurally, a constant-temperature water bath consists of a corrosion-resistant stainless steel inner liner, equipped with concealed heating elements and a high-efficiency temperature sensing system. Typical applications include maintaining the active temperature of culture media in microbiological experiments, controlling reaction rates in analytical chemistry, or preserving reagent stability in clinical testing. The equipment is usually equipped with multiple safety protection mechanisms, such as automatic power-off when dry-burning and abnormal temperature alarms, ensuring experimental accuracy while reducing operational risks. After use, any accumulated water should be drained promptly and the inner wall wiped clean. Circuit interfaces should be checked regularly to prevent aging. As a basic piece of laboratory equipment, the constant-temperature water bath, with its stable performance and ease of operation, has become the preferred tool for researchers conducting precision temperature-controlled experiments.

[0003] Traditional water baths typically have their inner liner welded or bolted to the main body. Because the inner liner cannot be easily disassembled, it is difficult for operators to thoroughly and effectively clean the inside of the liner, especially the corners and crevices. These accumulated scale and residues not only affect the hygiene of the equipment, but also significantly reduce heating efficiency over time. In addition, existing equipment lacks a dedicated fixing structure for containers such as beakers. During the heating process, water convection or equipment vibration can easily cause the container to tip over, resulting in solution spillage, instrument damage, and safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric thermostatic water bath to solve the problems mentioned in the background art, such as the difficulty in cleaning due to the non-removable inner liner of traditional water baths and the risk of tipping over due to the lack of a container fixing structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric thermostatic water bath, comprising a water bath body, an inner liner inside the water bath body, a partition and a perforated shelf fixedly connected to the inner wall of the inner liner, an electric heating tube fixedly connected inside the inner liner, a mounting part at the top of the inner liner, an insertion hole on the outer surface of the mounting part, a cover plate at the top of the water bath body, a through hole at the top of the cover plate, a fixing device fixedly connected to the upper surface of the cover plate, a first screw rotatably connected to the outer surface of the water bath body, a slider threadedly connected to the outer surface of the first screw, a connecting plate fixedly connected to the top of the slider, multiple connecting rods fixedly connected to the outer surface of the connecting plate, insertion rods fixedly connected to the ends of the connecting rods, and a fixing device comprising a U-shaped frame, with second screws threadedly connected to both sides of the U-shaped frame.

[0006] Preferably, a plug is fixedly connected to the bottom of the inner liner, a socket is fixedly connected to the bottom of the inner cavity of the water bath body, the heating element is located below the partition, and the perforated shelf is located above the partition.

[0007] Preferably, the outer surface of the water bath body is provided with multiple guide holes, the connecting rod passes through the guide holes, a handwheel is fixedly connected to the end of the first screw, the outer surface of the insertion rod is adapted to the inner surface of the insertion hole, a slot is provided on the top of the water bath body, and the outer surface of the mounting part is adapted to the inner surface of the slot.

[0008] Preferably, the bottom of the U-shaped frame is fixedly connected to the upper surface of the cover plate, a rotating block is fixedly connected to the end of the second screw, a connecting block is rotatably connected to the end of the second screw away from the rotating block, and a pressure plate is fixedly connected to the side of the connecting block away from the second screw.

[0009] Preferably, a rubber pad is fixedly connected to the side of the pressure plate away from the connecting block, a fixing plate is fixedly connected to the outer surface of the connecting block, and a guide groove is provided on the inner wall of the U-shaped frame.

[0010] Preferably, a guide rod is fixedly connected inside the guide groove, and the end of the fixing plate away from the connecting block is sleeved on the outer surface of the guide rod. Beneficial effects

[0011] This utility model provides an electrically heated constant-temperature water bath. It has the following beneficial effects: 1. This electric thermostatic water bath features a detachable inner liner and a linkage locking mechanism. The bottom of the inner liner has a plug that connects to the socket inside the main body for power supply. The top is initially positioned by embedding a slot into the mounting part. Rotating the handwheel drives the first screw to move the slider horizontally. The connecting plate and connecting rod push the plug rod into the insertion hole of the mounting part to complete the mechanical locking of the inner liner. When disassembling, rotating the handwheel in the opposite direction can release the lock, making it easy to remove the inner liner and thoroughly clean scale and residue. This allows for quick disassembly and assembly and facilitates deep cleaning.

[0012] 2. This electric thermostatic water bath, through a fixing device, has a U-shaped frame and a bidirectional second screw structure on the cover plate. The rotating block drives the screw to push the connecting block, so that the pressure plate moves horizontally along the guide rod. The rubber pads on the inner sides of the two pressure plates clamp the neck of the beaker, effectively resisting the impact and vibration of the water flow and preventing the container from tipping over. In addition, the sleeve design of the guide rod and the fixing plate ensures that the pressure plate moves in a straight line without deviation, avoiding uneven force on the container and breaking it, thus balancing stability and ease of operation.

[0016] like Figure 1-4As shown, this utility model provides an electric thermostatic water bath, including a water bath body 1. The water bath body 1 has an inner liner 2 inside. A partition 5 and a perforated shelf 7 are fixedly connected to the inner wall of the inner liner 2. An electric heating tube 6 is fixedly connected inside the inner liner 2. An installation part 8 is provided on the top of the inner liner 2. An insertion hole 11 is opened on the outer surface of the installation part 8. A cover plate 9 is provided on the top of the water bath body 1. A through hole 10 is opened on the top of the cover plate 9. A fixing device 19 is fixedly connected to the upper surface of the cover plate 9. A first screw 13 is rotatably connected to the outer surface of the water bath body 1. A slider 14 is threadedly connected to the outer surface of the first screw 13. A connecting plate 16 is fixedly connected to the top of the slider 14. A plurality of connecting rods 17 are fixedly connected to the outer surface of the connecting plate 16. An insertion rod 18 is fixedly connected to the end of the connecting rod 17. The fixing device 19 includes a U-shaped frame 191. A second screw 192 is threadedly connected to both sides of the U-shaped frame 191.

[0017] Specifically, a plug 3 is fixedly connected to the bottom of the inner liner 2, a socket 4 is fixedly connected to the bottom of the inner cavity of the water bath body 1, the heating element 6 is located below the partition 5, and the perforated shelf 7 is located above the partition 5. The plug 3 and the socket 4 work together to achieve a quick circuit connection between the inner liner 2 and the water bath body 1, ensuring that the heating element 6 is powered.

[0018] Specifically, the outer surface of the water bath body 1 has multiple guide holes 12, the connecting rod 17 passes through the guide holes 12, the end of the first screw 13 is fixedly connected to a handwheel 15, the outer surface of the insertion rod 18 is adapted to the inner surface of the insertion hole 11, the top of the water bath body 1 has a slot 20, the outer surface of the mounting part 8 is adapted to the inner surface of the slot 20, the guide holes 12 constrain the movement trajectory of the connecting rod 17 to ensure that the insertion rod 18 is accurately aligned with the insertion hole 11, the adaptation of the insertion rod 18 and the insertion hole 11 realizes the mechanical locking of the inner liner 2, and the cooperation between the slot 20 and the mounting part 8 completes the initial positioning of the inner liner 2 to prevent installation offset.

[0019] Specifically, the bottom of the U-shaped frame 191 is fixedly connected to the upper surface of the cover plate 9, the end of the second screw 192 is fixedly connected to the rotating block 193, the end of the second screw 192 away from the rotating block 193 is rotatably connected to the connecting block 194, and the side of the connecting block 194 away from the second screw 192 is fixedly connected to the pressure plate 195. The rotatable connection design between the second screw 192 and the connecting block 194 prevents the pressure plate 195 from rotating with the screw, ensuring that the pressure plate 195 only moves in a straight line.

[0020] Specifically, a rubber pad 196 is fixedly connected to the side of the pressure plate 195 away from the connecting block 194, a fixing plate 197 is fixedly connected to the outer surface of the connecting block 194, a guide groove 198 is provided on the inner wall of the U-shaped frame 191, and the rubber pad 196 increases friction and buffers pressure to prevent the glass beaker from being crushed.

The guide groove 198 and the guide rod 199 limit the movement direction of the fixing plate 197 to ensure that the pressure plate 195 moves without deviation.

[0022] The working principle of the above embodiments: When the electric thermostatic water bath is working, the control module of the water bath body 1 supplies power to the heating element 6 to heat the water in the inner tank 2. The partition 5 divides the inner tank 2 into upper and lower sections. The heating element 6 is located below the partition 5 for heating the water. The perforated shelf 7 is located above for placing containers such as beakers. The holes promote heat convection to achieve uniform and constant temperature heating. The through hole 10 of the cover plate 9 allows the neck of the container to extend. To prevent the container from shaking due to water convection or vibration during heating, a fixing device 19 can be used. Rotating the two rotating blocks 193 on both sides drives the second screw 192 to rotate. Since the end of the second screw 192 is rotatably connected to the connecting block 194, and the fixing plate 197 moves along the guide rod 199, the two pressure plates 195 can be horizontal. When the pressure plates 195 move close to each other, the rubber pads 196 on their surfaces press against the necks of containers such as beakers to prevent shaking during heating. The inner liner 2 is designed to be detachable. During installation, the inner liner 2 is placed into the main body 1 of the water bath, and the bottom plug 3 is inserted into the socket 4 inside the main body to connect the circuit of the heating element 6. At the same time, the mounting part 8 is snapped into the top slot 20. The handwheel 15 is rotated clockwise to drive the first screw 13 to rotate, which drives the slider 14 to move horizontally. The connecting plate 16 pushes the connecting rod 17 to move along the guide hole 12, so that the insertion rod 18 is inserted into the insertion hole 11 of the mounting part 8, thus completing the mechanical locking of the inner liner 2. During disassembly, the handwheel 15 is rotated counterclockwise to make the insertion rod 18 exit the insertion hole 11, and the inner liner 2 can be removed for cleaning and maintenance.
