[0052] The rotating head assembly 6 is provided with a head housing 61 and the head housing 6 can be arranged on the top of the housing 1 through a fixed chassis 8 and the heating coil 69, the mixing device 62, the conductivity measuring instrument 63, the micro-control device 64 and the temperature sensor 65 penetrate the housing 1, the tank 2 and the oil tank 3 and are arranged inside the right cavity 32;

The liquid medium inside the oil tank 3 can be cooled by the cooling circulation device 5, so as to provide a field source with controlled heat and cold and uniform and constant temperature.

[0056] Specifically, the heating coil 69 is fixedly connected to the wiring device 613 arranged inside the head shell 61, and the heating coil 69 is arranged inside the right cavity 32 and is designed in a spiral tube shape, which can increase the contact area between the heating coil 69 and the liquid medium inside the right cavity 32, increase the heating efficiency of the heating coil 69, and enable the liquid medium to quickly reach the specified temperature.

[0057] Specifically, the micro-control device 64 includes a float 641 arranged inside the right cavity 32 and a micro-switch 642 arranged inside the machine head shell 61. The float 641 is fixedly connected to a trigger block 644 arranged inside the machine head shell 61 through a guide rod 643, and the trigger block 644 can contact a contact 645 arranged on the micro-switch 642. The micro-switch 642 is arranged inside the machine head shell 61 and is fixedly connected to a circuit board 612 arranged inside the machine head shell 61. When the water level is high, the liquid medium in the oil tank 3 will force the trigger block 644 to move upward through the float 641, so that the trigger block 644 contacts the contact 645 arranged on the micro-switch 642, so that the micro-switch 642 is in an engaged state, and the wiring device 613 is controlled by the circuit board 612 to cause the heating coil 69 to heat the liquid medium in the oil tank 3. When the water level drops, the float 641 drops along with the water level to reset the trigger block 644, thereby turning the micro switch 642 off and stopping the heating coil 69.

[0058] Specifically, the mixing device 62 includes a motor 615 arranged inside the head shell 61 and the motor 615 is fixedly connected to the water pump shaft 621, the water pump shaft 621 is fixedly connected to the water pump 622 and the water pump shaft 621 is provided with a fan blade 623 and an agitator 624, the water pump shaft 621 passes through the through hole 82 provided on the fixed chassis 8, penetrates the head shell 61 and the water pump 622 and is arranged at the center of the water pump 622.

[0059] Specifically, the fan blade 623 is fixedly arranged at the center position inside the head shell 61 and the agitator 624 is arranged at the middle position of the right cavity 32. The fan blade 623 can dissipate heat inside the head shell 61 and the agitator 624 can circulate the liquid medium inside the oil tank 2.

A hollow connecting pipe 626 is provided on the water pump 622 and the hollow connecting pipe 626 is movably connected to a hollow hose 627. A spring 628 is provided on the outer sleeve of the hollow hose 627. The water pump 622 can cooperate with the agitator 624 to circulate the liquid medium inside the oil tank 3. Through the setting of the hollow hose 626, when the water level of the liquid medium exceeds the hollow hose 626, the liquid medium will circulate through the hollow hose 626 and the water pump 622, so as to circulate the liquid medium at different water levels, which can effectively ensure the constant temperature condition and reduce the accumulation of impurities.

[0061] Specifically, the partition 4 is provided with circulation holes 41 in a uniform array and penetrating the partition 4. The circulation holes 41 can circulate the liquid medium between the left chamber 32 and the right chamber 32, thereby ensuring that the temperature of the liquid medium in the oil tank 3 is uniform. By arranging the circulation holes 41 in a uniform array, the impact force of the stirring water flow of the agitator 624 can be dispersed to prevent the sample container from being knocked over by the water flow.

[0062] Specifically, the shell 1 is provided with heat dissipation holes 11 to facilitate the heat dissipation of the cooling circulation device 5, and the cover plate 12 is filled with heat-insulating material to prevent the temperature of the tank body 2 from dissipating.

The shell 1 is provided with a liquid inlet 13 and a liquid outlet 14 to facilitate the liquid medium to enter and exit the tank body 2. The tank cover 12 is also provided with a handle to facilitate the opening and closing of the tank cover 12. The rear of the shell 1 is provided with a communication interface, a fuse, a power interface and a switch, and handles are provided on the left and right sides of the outer wall of the shell 1 to facilitate the movement and transportation of the constant temperature bath by the experimenter.

[0063] Specifically, a motor drive 614 is provided inside the head shell 61, and the circuit board 612, the wiring device 613, the motor drive 614, the conductivity meter 63, the micro-control device 64, the temperature sensor 65, the cooling circulation device 5 and the display screen provided on the head shell 61 are electrically connected. The temperature data monitored by the temperature sensor 65 and the conductivity meter 63 can be displayed on the display screen provided on the head shell 61, and the display screen can independently control the start-up of the cooling circulation device 5, the motor drive 614 and the wiring device 613. A storage device is provided inside the display screen to automatically save temperature data and conductivity data, and can be displayed on the display screen in the form of a curve, so that the entire constant temperature process is clear.

[0064] Working principle: When assembling the thermostatic bath with the self-test function of organic content, the rotating head assembly 6 is fixed on the shell 1 through the fixed chassis 8 arranged below it. The rotating head assembly 6 and the shell 1 can be fixed by screws or screws through the connecting holes 84 arranged on the fixed chassis 8, and the rotating head assembly 6 can rotate left and right relative to the fixed chassis 8 and the shell 1. When it is necessary to repair the heating coil 69, the mixing device 62 or other devices, it is only necessary to detach the fixed chassis 8 from the shell 1 to take out the entire rotating head assembly 6. There is no need to disassemble the shell 1 and the rotating head assembly 6 separately, which saves working time.

[0065] When the thermostatic bath with the self-checking function of organic matter content is used to keep the sample placed in the glass instrument at a constant temperature, the cover plate 12 is first opened, the sample container is placed inside the left cavity 31, and then the cover plate 12 and the shell 1 are tightly closed, and the device power is started. By using the heating coil 69, the cooling circulation device 5 and the mixing device 62 arranged inside the device in combination, a field source with controlled heat and cold and uniform and constant temperature can be provided. By setting the microcontroller 64 and electrically connecting the circuit board 612, the motor drive 614, the wiring device 613, the temperature sensor 65 and the cooling circulation device 5, the start of the heating coil 59 and the cooling circulation device 5 can be controlled according to the water level, and the oil tank 3 can be automatically heated and cooled according to the water level of the liquid medium inside the oil tank 3, and the condition of automatic constant temperature under different water level conditions can be met;

[0066] When the thermostatic bath with the self-checking function of organic content is used for the solid or metal sample directly placed in the oil tank 3, the cover plate 12 is first opened, and the solid or metal sample is placed on the placement net 312 arranged inside the left cavity 31, and then the cover plate 12 and the shell 1 are tightly closed, and the device power is started. By using the heating coil 69, the cooling circulation device 5 and the mixing device 62 arranged inside the device, a field source with controlled heat and cold and uniform and constant temperature can be provided, and the conductivity meter 63 can measure the concentration of inorganic acids, alkalis and salts contained in the liquid medium to prevent temperature fluctuations and contamination of the solid or metal sample.
