[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-6 This utility model provides a magnetic stirring low-temperature constant temperature reaction bath for testing, including a bath body 1 and an inner layer 901. A drive motor 12 is fixedly connected to the bottom end of the inner layer 901. A magnetic coupler 13 is rotatably connected to the output end of the drive motor 12. A stirrer 10 is rotatably connected to the center of the upper end of the magnetic coupler 13. During operation, after the drive motor 12 starts, it drives the magnetic coupler 13 at the output end to rotate. The magnetic coupler 13 drives the stirrer 10 at the upper end to rotate through magnetic force. The stirrer 10 stirs the test liquid in the inner layer 901 of the bath body 1, realizing uniform mixing of the liquid. The use of magnetic coupling transmission avoids the leakage problems that may occur in traditional mechanical transmission, improves the sealing and safety of the device, and ensures the stable operation of the test process. The drive motor is a brushless DC motor, which is connected to the control module through a frequency converter.

[0018] Furthermore, such as Figure 2 and Figure 3 As shown, an outer layer 903 is fixedly connected to the center of the upper end of the bath body 1. An insulation layer 902 is fixedly connected to the inner side of the outer layer 903. An inner layer 901 is fixedly connected to the inner side of the insulation layer 902. A base plate 8 is fixedly connected to the bottom of the bath body 1. A cover plate 201 is fitted onto the top of the inner layer 901. A cover plate handle 202 is fixedly connected to the center of the top of the cover plate 201. During operation, the outer layer 903, the insulation layer 902, and the inner layer 901 together constitute the multi-layer protective structure of the bath. The outer layer 903 provides basic protection. The insulation layer 902 can effectively reduce the heat exchange between the test environment inside the inner layer 901 and the outside, maintain the internal temperature stability, and ensure the low-temperature constant temperature effect. The base plate 8 provides stable support for the bath body 1, making it more stable when placed. The cover plate 201 can be fitted onto the top of the inner layer 901 to reduce internal heat loss and the entry of external impurities. The cover plate handle 202 makes it easy to pick up and place the cover plate 201, making operation convenient. Furthermore, such as Figure 2As shown, the inner layer 901 is made of corrosion-resistant stainless steel, the outer layer 903 is a heat-insulating and noise-reducing composite board, and the insulation layer 902 is made of polyurethane insulation cotton. During operation, the corrosion-resistant stainless steel inner layer 901 can effectively resist the erosion of various corrosive liquids during the test, extend the service life of the inner layer 901, and ensure the safety and reliability of the test. The heat-insulating and noise-reducing composite board of the outer layer 903 can further block the inflow of external heat or the outflow of internal heat, help maintain a constant temperature environment, and reduce the noise generated during the operation of the device, thus improving the test operating environment. The polyurethane insulation cotton of the insulation layer 902 has excellent heat insulation performance, which can significantly reduce heat loss, improve the energy utilization efficiency of the device, and ensure that the temperature inside the inner layer 901 is stable within the low-temperature constant temperature range required for the test. Furthermore, such as Figure 1 and Figure 2 As shown, a fixed column 3 is fixedly connected to one corner of the top of the bath body 1. A sliding block 4 is sleeved on the outer surface of the fixed column 3. During operation, the fixed column 3 provides a base for the installation and movement of the sliding block 4. The sliding block 4 can slide up and down along the outer surface of the fixed column 3. The position of the sliding block 4 can be adjusted according to the test requirements. The sliding block 4 can be used to install auxiliary components required for the test, such as clamps, to facilitate the fixing or adjustment of the test container and improve the flexibility and convenience of the test operation. Furthermore, such as Figure 1 As shown, a control panel 5 is fixedly connected to the surface of the bath body 1, and a display screen 6 is fixedly connected to the surface of the control panel 5. Several slots 7 are evenly opened on the lower side of the bath body 1. During operation, the operator can set and adjust the operating parameters of the device through the control panel 5, such as stirring speed and constant temperature. The display screen 6 can display the operating status and various parameters of the device in real time, so that the operator can intuitively understand the test situation and promptly detect and deal with abnormal problems. The slots 7 can be used for heat dissipation of the device to avoid excessive internal temperature affecting the service life and operational stability of the components. On the other hand, they can also be used as mounting holes to facilitate the fixed installation of the device. Furthermore, such as Figure 5 and Figure 6 As shown, a drain port 1501 is fixedly connected to the bottom end of the outer layer 903, and a drain valve 1502 is rotatably connected to the surface of the drain port 1501. During operation, when the test is completed or the inside of the bath needs to be cleaned, the drain valve 1502 is opened, and the waste liquid or cleaning wastewater in the inner layer 901 can be discharged through the drain port 1501 without manual dumping. The operation is simple and convenient, reducing the labor intensity of the operators. The drain valve 1502 can effectively control the opening and closing of the drain port 1501. During normal testing, the drain valve 1502 is closed to prevent liquid leakage and ensure the normal progress of the test.

[0019] Furthermore, such as Figure 4As shown, a heating tube 1402 is fixedly connected to the inner side of the inner layer 901. A corrosion-resistant heat-conducting sleeve 1401 is fitted onto the surface of the heating tube 1402. A temperature sensor 11 is fixedly connected to the bottom of the inner layer 901. During operation, the heating tube 1402 is controlled by the control panel 5 according to the temperature requirements of the test. The heat generated by the heating tube 1402 is transferred to the liquid inside the inner layer 901 through the corrosion-resistant heat-conducting sleeve 1401, thereby heating the liquid. The corrosion-resistant heat-conducting sleeve 1401 can ensure effective heat transfer and protect the heating tube 1402 from corrosion by corrosive liquids, thus extending the service life of the heating tube 1402. The temperature sensor 11 monitors the temperature of the liquid inside the inner layer 901 in real time and transmits the temperature signal to the control panel 5. The control panel 5 automatically adjusts the working state of the heating tube 1402 according to the signal fed back by the temperature sensor 11, so that the temperature inside the inner layer 901 is stabilized within the set constant temperature range, ensuring the accuracy and stability of the test conditions. Working Principle: This test utilizes a magnetically stirred low-temperature constant-temperature reaction bath. First, the cover 201 is opened via the handle 202, and the liquid to be tested is placed into the inner layer 901. Then, the cover 201 is closed. The required stirring speed and constant-temperature parameters are set via the control panel 5, and the display screen 6 shows the relevant parameters and the device's operating status in real time. The drive motor 12 starts, driving the stir bar 10 to rotate via the magnetic coupler 13, stirring the liquid in the inner layer 901 to achieve uniform mixing. Simultaneously, the temperature sensor 11 monitors the liquid temperature in the inner layer 901 in real time and transmits the signal to the control panel 5. If the temperature is lower than the set value, the control panel 5 controls the heating element 1402 to operate. The heating element 1402 transfers heat to the liquid in the inner layer 901 through the anti-corrosion heat-conducting sleeve 1401. When the temperature reaches the set value, the control panel 5 controls the heating element 1402 to stop heating or adjust the heating power to maintain a stable temperature. The outer layer 903 and the insulation layer 902 reduce heat exchange between the inside and outside, ensuring a constant-temperature effect. During the test, auxiliary components can be installed via the sliding block 4 on the fixed column 3 to facilitate test operation. After the test, the drain valve 1502 is opened to discharge waste liquid through the drain port 1501. The slot 7 on the lower side of the bath body 1 provides heat dissipation and auxiliary installation functions, and the base plate 8 ensures the stable placement of the device.
