Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a magnetic stirrer provided with an automatic water replenishment structure, including a base 1, a control panel 2, an outer shell 3, a clamping block 4, an inner shell 5, a heating wire 6, an annular tube 7, a water level sensor 8, a material box 9, a convex block 10, a limiting edge 11, a connection shell 12, a cylinder 13, a connecting plate 14, a temperature sensor 15, and an electromagnet 16.

[0031] Embodiment 1: The magnetic stirrer is provided with an automatic water replenishment structure, which can replenish water to the inner shell 5 in time to avoid dry burning. Specifically:

[0032] The front surface of the shown base 1 is provided with a control panel 2, and further includes an electromagnet 16 which is embedded and installed on the bottom surface of the inner wall of the base 1. The upper surface of the base 1 is alone installed with a housing 3. The housing 3 is connected with an automatic water replenishing structure which can uniformly inject water into the interior of the inner shell 5 through the annular pipe 7. The automatic water replenishing structure includes a clamping block 4 which is fixedly installed at the upper end of the housing 3. The lower surface of the clamping block 4 is fixedly connected with the upper end of the inner shell 5. The inner shell 5 is located inside the housing 3. A sandwich layer is formed between the housing 3 and the inner shell 5. A heating wire 6 is installed in a surrounding manner between the sandwich layers. The inner wall surface of the inner shell 5 is embedded with an annular pipe 7. The outer surface of the annular pipe 7 is provided with spray nozzles at equal intervals. The bottom surface of the inner wall of the housing 3 is installed with a water level sensor 8. The rear end of the annular pipe 7 is provided with a water inlet which penetrates through the rear surface of the housing 3. The water level sensor 8 is connected to the valve of the annular pipe 7 for control;

[0033] When the magnetic stirrer is in use, first, the convex block 10 fixedly installed at the upper end of the material box 9 is placed on the upper surface of the clamping block 4, and then the material box 9 is suspended into the interior of the inner shell 5, so that the water inlet penetrating through the rear surface of the housing 3 and arranged at the rear end of the annular pipe 7 is connected to a water source. The water level sensor 8 installed on the bottom surface of the inner wall of the housing 3 monitors the water quantity state inside, and will control the valve of the annular pipe 7 to open. Then, the water flow will be evenly added into the inner shell 5 through the spray nozzles arranged at equal intervals on the outer surface of the annular pipe 7. A sandwich layer is formed between the inner shell 5 and the housing 3. The heating wire 6 installed between the sandwich layers is turned on, and the water in the housing 3 will be heated, so that the water in the material box 9 can be heated. Since the material box 9 is suspended in the inner shell 5 and is in uniform contact with the water, the material box 9 can be heated evenly. By monitoring the change of the water quantity through the water level sensor 8, the dry burning state inside can be avoided, and the interruption of the experiment caused by dry burning can be avoided, ensuring the smooth progress of the material mixing and stirring. Especially for the long-term running mixing and stirring, its function is more important. And by evenly adding water through multiple nozzles of the annular pipe 7, the sudden cooling of the water inside can also be avoided, making the material mixing effect better.

[0034] Embodiment 2: The magnetic stirrer is further provided with a temperature sensing structure which can control the temperature sensor 15 to enter the material box 9 for monitoring. Specifically:

[0035] The housing 3 is connected with a temperature sensing structure which can monitor the materials in the material box 9 by moving the temperature sensor 15. The temperature sensing structure includes a material box 9. A convex block 10 is fixedly installed at the upper end of the material box 9. A limiting edge 11 is fixedly installed on the inner wall surface of the material box 9. A connecting shell 12 is installed through the outer surface of the housing 3. A cylinder 13 is fixedly installed on the inner wall surface of the connecting shell 12. The push rod of the cylinder 13 is fixedly connected with a connecting plate 14. A temperature sensor 15 is fixedly installed on the lower surface of the connecting plate 14. A slot is arranged on the outer surface of the material box 9, and the slot corresponds to the connecting shell 12;

[0036] Further, after the material box 9 is placed into the inner shell 5, add the material to be stirred into the material box 9. There is a limiting edge 11 provided on the inner wall surface of the material box 9. When adding the material, it is necessary to control the material not to exceed the height of the limiting edge 11. Then, place the stirring magnet block into the material box 9. Control the electromagnet 16 to turn on through the control panel 2 on the front surface of the base 1. The stirring magnet block will rotate in the material box 9 to stir the material by the electromagnet 16. As Figure 6 shown, a temperature sensor 15 is provided in the connecting shell 12 installed through the outer surface of the outer shell 3. The cylinder 13 fixedly installed on the inner wall surface of the connecting shell 12 can push the connecting plate 14 to move, and the connecting plate 14 will drive the temperature sensor 15 to move. As Figure 1 shown, the grooved position provided on the outer surface of the material box 9 corresponds to the connecting shell 12. Therefore, the cylinder 13 can push the connecting plate 14 to drive the temperature sensor 15 to move into the material box 9. The temperature sensor 15 monitors the temperature of the material in the material box 9, which is convenient for timely adjustment. When the temperature exceeds the set safety threshold, an alarm can be issued in time or the heating can be automatically stopped to avoid equipment damage caused by too high temperature. It can also accurately monitor the temperature of the material stirring in real time to ensure that the material is within the required temperature range, thus greatly improving the effect of material mixing.

[0037] Working principle: When using this magnetic stirrer with an automatic water replenishment structure, there is an automatic water replenishment structure that can timely replenish water to the inner shell 5 through the annular pipe 7 to avoid dry burning. There is also a temperature sensing structure that can push the temperature sensor 15 into the material box 9 by the cylinder 13, increasing the overall practicality.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
