Description

Technical Field

[0001] This utility model relates to the field of water bath technology, specifically a water bath with a magnetic stirring structure. Background Technology

[0002] As is well known, in experimental fields such as biology, genetics, medicine, and chemical engineering, constant-temperature water baths are key equipment for achieving constant-temperature heating of samples. However, existing technologies for traditional constant-temperature water baths have several limitations: some devices lack effective stirring structures, relying on natural convection of water to achieve uniform temperature, resulting in significant temperature differences between different areas within the heating chamber, affecting the accuracy of experimental results; some water baths with stirring functions suffer from insufficient coordination between the stirring system and the heating structure, leading to low stirring efficiency and poor temperature control accuracy. Furthermore, the top cover and heating chamber of traditional water baths often use a simple snap-fit ​​design, which is not securely fixed and easily shifts due to vibration during experiments. Disassembly is also inconvenient, making cleaning of the heating chamber and maintenance of internal components difficult. In addition, the heating tubes, as the core heating component, are prone to scale and impurities accumulating on their surface after long-term use. The structural design of traditional equipment exposes the heating tubes, making maintenance cumbersome and increasing maintenance difficulty. Therefore, it is necessary to propose solutions to this technical problem. Summary of the Invention

[0006] Furthermore, the present invention is improved in that the magnetic stirring mechanism is provided with multiple components.

[0007] Furthermore, the present invention is improved in that the water receiving mechanism includes an installation pipe and a water guide hole. The installation pipe is installed on one side of the water bath body, and the water guide hole is opened on one side of the heating box. One end of the installation pipe is connected to the installation groove through a sealing sleeve. The water guide hole is aligned with the installation pipe. An electric valve is provided between the installation pipe and the interior of the water bath body. Both the installation pipe and the water guide hole are provided in two sets.

[0008] Furthermore, the present invention is improved by providing a quick connector on the mounting tube.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model relates to a water bath with a magnetic stirring structure, comprising a water bath body 1, a control mechanism 2 on the water bath body 1, an installation groove at the top of the water bath body 1, a heating box 3 on the installation groove, a heating cavity at the top of the heating box 3, a heating tube 4 on the heating cavity, a wiring port at the bottom of the heating box 3, a wiring connector 5 on the installation groove, the heating cavity and the water bath body 1 being connected by a water receiving mechanism, a shelf 6 on the heating cavity, a top cover 7 at the top of the heating cavity, a fastening box 8 at the top of the top cover 7, an adjusting shaft 9 inside the fastening box 8 extending to both ends of the fastening box 8, an adjusting gear 10 on the adjusting shaft 9, a fastening groove inside the top cover 7 connecting its two ends, a bidirectional lead screw 11 on the fastening groove, a bearing seat and a drive gear 12 on the bidirectional lead screw 11, and an adjusting gear 10. The drive gear 12 is engaged with the bidirectional lead screw 11. Inclined plates 13 are provided at both ends of the bidirectional lead screw 11, and threaded holes are provided on the inclined plates 13. The bidirectional lead screw 11 passes through the threaded holes. Inclined grooves are provided on both sides of the heating chamber. A magnetic stirring mechanism is provided between the heating box 3 and the water bath body 1. In this embodiment, a control mechanism 2 is provided on the water bath body 1 to control the operation of the equipment. An installation groove is provided at the top of the water bath body 1 for placing the heating box 3. The heating chamber at the top of the heating box 3, in conjunction with the heating tube 4, provides a heating environment for the items placed inside. The wiring interface at the bottom of the heating box 3 is connected to the wiring connector 5 on the installation groove to ensure the power supply line connection of the heating tube 4. This allows the heating box 3 to be directly powered through the wiring interface and the wiring connector 5. A water receiving mechanism between the heating chamber and the water bath body 1 facilitates the supply of water into or out of the heating chamber. A shelf 6 is provided on the heating chamber for convenient placement of items to be heated. An adjusting shaft 9 is provided in the fastening box 8 at the top of the top cover 7. The adjusting shaft 9 extends to both ends and has adjusting gears 10. There is a double-acting screw 11 in the fastening groove inside the top cover 7. The double-acting screw 11 is supported by a bearing seat and has a drive gear 12 that meshes with the adjusting gear 10.When the adjusting shaft 9 is rotated, the adjusting gear 10 drives the driving gear 12, which in turn causes the bidirectional lead screw 11 to rotate. The two ends of the bidirectional lead screw 11 pass through the screw holes on the inclined plate 13. Since the inclined plate 13 is confined in the fastening groove, it can move linearly and abut against the inclined groove on the side of the heating chamber, thereby fastening the top cover 7 to the heating box 3. By using the magnetic stirring mechanism, the liquid inside the item can be stirred, which can accelerate the uniform heating of the liquid. During later maintenance, by lifting the top cover 7, the inclined plate 13 abuts against the inclined groove, thereby lifting the top cover 7 and the heating box 3, which facilitates the maintenance of the heating tube 4. It also facilitates the maintenance of the interior of the water bath body 1 through the exposed mounting groove. When it is necessary to clean the heating chamber, by rotating the bidirectional lead screw 11, the inclined plate 13 can be removed from the inclined groove, making it easy to remove the top cover 7 and clean the heating chamber. The control mechanism includes an LCD display, control buttons and circuit modules for adjusting parameters such as temperature, stirring speed and timing. The control mechanism is existing technology, so it will not be described in detail in this structure.

[0020] To facilitate the stirring of liquid inside the bottle, the magnetic stirring mechanism in this design includes a drive device 14, a stir bar, and a slot. The drive device 14 is installed at the bottom of the water bath body 1 and extends into the mounting slot. The slot is formed on the top cover 7, and a top shell 15 is provided at the slot. Multiple magnetic stirring mechanisms are provided. By opening the top shell 15, the bottle can be placed into the heating chamber area corresponding to the slot and supported by the shelf 6. The stir bar is placed inside the bottle in the heating chamber. The magnetic field generated by the drive device 14 drives the stir bar to rotate, thereby stirring the liquid inside the bottle. Since multiple magnetic stirring mechanisms are provided, multiple drive devices 14 can control the stir bar in the corresponding bottle, enabling more precise stirring of the liquid inside the bottle.

[0021] To facilitate water supply or drainage to the heating chamber, in this design, the water receiving mechanism includes an installation pipe 16 and a water guide hole 17. The installation pipe 16 is installed on one side of the water bath body 1, and the water guide hole 17 is located on one side of the heating chamber 3. One end of the installation pipe 16 is connected to the installation groove via a sealing sleeve 18. The water guide hole 17 is aligned with the installation pipe 16. An electric valve 19 is provided between the installation pipe 16 and the interior of the water bath body 1. Both the installation pipe 16 and the water guide hole 17 are provided in two sets. A quick connector 2 is provided on the installation pipe 16. 0. After the heating box 3 is assembled in the mounting slot, the water guide hole 17 is aligned with the mounting pipe 16. One end of the mounting pipe 16 is connected to the water guide hole 17 through a sealing sleeve 18 to ensure the sealing of the connection and prevent water leakage. An electric valve 19 is provided between the mounting pipe 16 and the inside of the water bath body 1 to control whether the water flow enters the inside of the water bath body 1. The mounting pipe 16 and the water guide hole 17 are provided in two sets to facilitate the delivery of water to or from the heating chamber. The quick connector 20 on the mounting pipe 16 facilitates quick connection and disassembly with external drainage devices, etc.

[0022] To facilitate lifting or closing the top cover 7, this design includes two handles 21 at the top of the top cover 7, arranged symmetrically. The handles 21 are ergonomically designed, significantly improving ease of operation. During experiments, operators can easily lift or close the top cover 7 using the handles 21, reducing operational difficulty and improving experimental efficiency.

[0023] To facilitate gripping the rotating adjustment shaft 9, in this design, handles are provided at both ends of the adjustment shaft 9. The handles enhance the convenience and controllability of operating the adjustment shaft 9, making rotation easier and allowing for more precise control of the rotation angle of the adjustment shaft 9.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
