Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment technology, and in particular to a magnetic stirrer. Background Technology

[0002] Magnetic heating stirrers are mainly used in fields such as medicine and experimental research. They work by using an electric motor to drive a magnet to rotate, which in turn causes the stir bar in the container above the tray to rotate, thus completing the stirring work. For example, in the process of cosmetic production, the mixing of raw materials requires the use of a magnetic stirrer. Magnetic stirrers are widely used in cosmetic production due to their advantages such as no mechanical contact and uniform mixing.

[0003] When the stirrer rotates too fast or is subjected to external impact, the beaker is prone to shaking, causing liquid to splash out, which can lead to the equipment being scrapped and personnel being injured. When the stirrer is not in use, it is left aside, and the parts are not easy to store. When it is necessary to replace the parts, they are also difficult to find. When the stirrer is not in use, there are no matching components provided with it. It is just left aside to collect dust or covered with a cloth, which takes up a lot of space.

[0004] The existing patent (publication number: CN208711601U) discloses a magnetic heating stirrer for cosmetic experiments. The support of this utility model can be adjusted according to the size of the beaker to provide support for the temperature sensor. It is simple, convenient and quick. The design of the protective cover reduces the phenomenon of liquid splashing caused by the beaker shaking due to the excessive speed of the stir bar or external impact. The receiving cavity and storage compartment complete the storage work.

[0005] To address the aforementioned issues, existing patents offer solutions. However, in the magnetic heating stirrer for cosmetic experiments described in these patents, the threaded hole for fixing the support rod presents numerous inconveniences in actual use. When not in use, the dust cover needs to be placed on the base, requiring the support rod to be manually rotated out of the threaded hole. Subsequent use necessitates manual reinstallation. This process is extremely cumbersome in scenarios involving frequent stirrer use, wasting considerable time and effort, reducing work efficiency, and causing frequent thread wear, affecting connection stability, increasing maintenance costs and the frequency of parts replacement, significantly impacting product usability. Furthermore, the combined use of the protective cover and dust cover presents problems. The dust cover must be opened when using the protective cover and removed when closing it. This method is not only inconvenient but also prone to being neglected by researchers due to the perceived inconvenience, increasing experimental safety risks. Additionally, the protective cover may be carelessly placed when closing the dust cover, easily leading to its loss or damage, which is detrimental to the long-term use and maintenance of the equipment.

[0006] Therefore, a magnetic stirrer is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a magnetic stirrer that solves the numerous inconveniences of the threaded hole for fixing the support rod in the aforementioned magnetic heating stirrer for cosmetic experiments. When not in use, the dust cover needs to be placed on the base, at which point the support rod needs to be manually rotated to disengage from the threaded hole. Subsequent use requires manual reinstallation, a process that is extremely cumbersome in scenarios with frequent stirrer use. This not only wastes a lot of time and effort and reduces work efficiency, but also causes frequent twisting, leading to thread wear, affecting connection stability, increasing maintenance costs and the frequency of parts replacement, and significantly impacting product usability. Furthermore, the combined use of the protective cover and dust cover also presents problems. The dust cover must be opened when using the protective cover and removed when closing it. This is not only inconvenient, but in actual experimental operations, personnel may neglect to use the protective cover due to the inconvenience, increasing experimental safety risks. Alternatively, the protective cover may be carelessly placed when closing the dust cover, easily leading to its loss or damage, which is detrimental to the long-term use and maintenance of the equipment.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A magnetic stirrer includes a base 1, a magnetic stirring structure 2 at the bottom of the base 1, a beaker 3 at the top of the magnetic stirring structure 2, a support mechanism 4 at the top of the base 1, and a transparent protective structure 5 at the top of the base 1.

[0030] The support mechanism 4 includes a recessed groove 41 located on the rear side of the top of the base 1. A rotating block 42 is rotatably connected to the right side inside the recessed groove 41. A magnetic block 43 is fixedly connected to the right side inside the recessed groove 41. A strong magnetic sheet 44 is fixedly connected to the right side of the rotating block 42. The strong magnetic sheet 44 is magnetically connected to the magnetic block 43. A support rod 45 is fixedly connected to the top of the rotating block 42. An adjusting sleeve 46 is bolted to the top of the outer side of the support rod 45. A positioning sleeve rod 47 is rotatably connected to the front side of the adjusting sleeve 46. A temperature sensor 48 is installed inside the front side of the positioning sleeve rod 47. The bottom of the temperature sensor 48 is located inside the beaker 3. A placement groove 49 is provided on the right side of the top of the base 1.

[0031] In this embodiment: by setting up a magnetic stirring structure 2, a support mechanism 4, and a transparent protective structure 5, after the magnetic stirring structure 2 is activated, the rotating magnetic field it generates drives the magnetic stir bar inside the beaker 3 to rotate rapidly, making the solution uniformly mixed and providing good conditions for the experimental reaction. The support mechanism 4 is ingeniously designed, with a concealed groove 41, a rotating block 42, a magnetic block 43, and a strong magnetic sheet 44 working together. When not in use, the support rod 45, the adjusting sleeve 46, and the positioning sleeve rod 47 are stored in the concealed groove 41, reducing space occupation. When in use, rotating the rotating block 42 causes the strong magnetic sheet 44 and the magnetic block 43 to attract each other, quickly fixing the support rod 45 vertically. The top adjustment sleeve 46 and positioning sleeve 47 of the support rod 45 precisely control the position of the temperature sensor 48, providing key data for real-time monitoring of the solution temperature. After the experiment, the rotating block 42 is rotated in the reverse direction to return to its original position, avoiding frequent disassembly and damage. The transparent protective structure 5 has multiple functions: it can be closed during the experiment to prevent liquid splashing and ensure personnel safety; the base 1 can be covered before and after the experiment to prevent dust; the transparent material facilitates observation of the experiment; it can be opened during operation and closed during work, eliminating the need for frequent disassembly and facilitating equipment maintenance, thus improving experimental safety and convenience. Overall, it meets different experimental needs and is compatible with various sizes of beakers 3, enhancing the product's practicality and versatility.

[0032] Specifically, such as Figure 5 As shown, the transparent protective structure 5 includes a fixed sleeve 51 fixedly connected to the rear side of the base 1, and a rotating block 52 is rotatably connected to the inner side of the fixed sleeve 51.

[0033] Specifically, such as Figure 5 As shown, a protective frame 53 is bolted to the front side of the rotating block 42, and the protective frame 53 is located on the top of the base 1.

[0034] Specifically, such as Figure 5 As shown, transparent dustproof isolation panels 54 are fixedly connected to the outer perimeter and bottom of the protective frame. The transparent dustproof isolation panels 54 are made of transparent acrylic material.

[0035] In this embodiment: by setting a transparent protective structure 5, the cooperation between the fixed sleeve 51 and the rotating block 52 allows the protective frame 53 to be opened and closed flexibly by rotation. When an experiment is required, the protective frame 53 can be opened by rotating the rotating block 52 to facilitate the placement or removal of the beaker 3, etc. After the experiment begins, the protective frame 53 is rotated to cover the top of the base 1. The transparent dustproof isolation plate 54 around and at the bottom of the protective frame 53 is made of transparent acrylic material, which can effectively block liquids that may splash out during stirring, protect the safety of the experimenters, and does not hinder the experimenters from observing the experimental situation. When the equipment is not in use, the protective frame 53 is closed, and the transparent dustproof isolation plate 54 can prevent dust from entering the interior, reduce the frequency of equipment cleaning and maintenance, and extend the service life of the equipment.

[0036] Specifically, such as Figure 4As shown, the magnetic stirring structure 2 includes a tray 21 disposed on the top of the base 1, and the top of the tray 21 contacts the bottom of the beaker 3.

[0037] Specifically, such as Figure 4 As shown, an electric heating wire 22 is installed inside the tray 21, and a servo motor 23 is installed inside the base 1. A magnet 24 is fixedly connected to the output end of the servo motor 23.

[0038] In this embodiment: by setting up a magnetic stirring structure 2, the tray 21 serves as a component to support the beaker 3. The electric heating wire 22 inside the tray generates heat after being energized, which can heat the solution in the beaker 3 to meet the temperature requirements of different experiments. At the same time, after the servo motor 23 inside the base 1 is started, it drives the magnet 24 at the output end to rotate. The rotating magnetic field generated by the magnet 24 will act on the magnetic stir bar inside the beaker 3, driving the stir bar to rotate, thereby stirring the solution. This design that combines stirring and heating functions can make the solution heat more evenly during the stirring process, accelerate the chemical reaction or mixing process, and improve the experimental efficiency and the accuracy of the experimental results.

[0039] Specifically, such as Figure 3 As shown, a display screen 6 and a control button 7 are respectively provided on the front side of the base 1. The display screen 6 is electrically connected to the control button 7, the temperature sensor 48, the electric heating wire 22 and the servo motor 23.

[0040] Specifically, such as Figure 2 As shown, both sides of the protective frame 53 are fixedly connected to a lifting handle 8, and the outer side of the lifting handle 8 is arc-shaped.

[0041] In this embodiment: by setting up a display screen 6, control buttons 7, and lifting handles 8, the control buttons 7 serve as a key component for human-computer interaction. Experimenters can easily control parameters such as the rotation speed of the servo motor 23 and the heating temperature of the electric heating wire 22 through it, meeting the diverse needs of different experiments. The display screen 6 displays key data such as the solution temperature and stirring speed measured by the temperature sensor 48 in real time, allowing experimenters to intuitively understand the experimental process and easily adjust experimental parameters in a timely manner to ensure the accuracy and stability of the experiment. The lifting handles 8 on both sides of the protective frame 53 are designed in an arc shape, which conforms to the ergonomic principle, making it convenient for experimenters to grip and making it easier to open or close the protective frame 53. At the same time, it also reduces the risk of damage to the protective frame 53 due to inconvenient operation, further improving the ease of use of the equipment.

[0042] Working Principle: When using the magnetic stirrer, first place beaker 3 on tray 21, then add the magnetic stir bar into beaker 3. After connecting the power, start the device via control button 7 on the front of base 1. Control button 7 is electrically connected to display screen 6, temperature sensor 48, heating wire 22, and servo motor 23. Parameters such as stirring speed and heating temperature can be set. After startup, the servo motor 23 inside base 1 drives the magnet 24 at the output end to rotate. The magnet 24 generates a rotating magnetic field, driving the magnetic stir bar in beaker 3 to rotate rapidly, achieving uniform mixing of the solution. Simultaneously, the heating wire 22 inside tray 21 is energized and heats the solution, ensuring more uniform heating during stirring, accelerating chemical reactions or mixing, and meeting the experimental requirements for stirring and temperature. Before the experiment, rotate the rotating block 52 connected to the fixed sleeve 51 to open the protective frame 53 for easy placement of beaker 3. After the experiment begins, rotate the protective frame 53 to cover the top of base 1, which is a transparent dustproof isolation plate made of transparent acrylic material. 54 prevents liquid splashing, ensuring personnel safety, while not hindering observation of the experiment. When the equipment is not in use, the protective frame 53 is closed to prevent dust from entering. During the experiment, rotating the rotating block 42 in the hidden groove 41 causes the strong magnetic sheet 44 to attract the magnetic block 43, quickly fixing the support rod 45 vertically. The adjusting sleeve 46 and positioning sleeve 47 on the top of the support rod 45 can precisely adjust the position of the temperature sensor 48 in the beaker 3, monitor the solution temperature in real time, and feed the data back to the display screen 6, allowing the experimenter to adjust the experimental parameters according to the actual situation. After the experiment, rotating the rotating block 42 in the opposite direction returns the support rod 45, adjusting sleeve 46, and positioning sleeve 47 to the hidden groove 41, avoiding frequent disassembly that could damage parts. The temperature sensor 48 is then removed from the positioning sleeve 47 and placed in the placement groove 49. The entire process, through the coordinated work of various structures, meets different experimental needs, adapts to various sizes of beakers 3, enhances the practicality and versatility of the product, improves the convenience and safety of experimental operations, and ensures accurate and reliable experimental data.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
