Description

Technical Field

[0001] The present invention relates to the technical field of medical testing, and specifically to a homogenizing device for medical testing with a temperature control function. Background Art

[0002] A homogenizer, also called an adjustable high-speed homogenizer, is a conventional device for scientific research institutions, medical and epidemic prevention stations, and hospitals for testing. The homogenizer can perform functions such as fine crushing, homogenization, emulsification, dispersion, strong stirring, moistening, and dissolving organic or inorganic substances. It has the characteristics of stable performance, compact structure, beautiful appearance, easy use, safety and reliability, and extremely high working efficiency.

[0003] In the use of existing homogenizing devices, it is necessary to heat the samples, but there will be a phenomenon of uneven temperature. Local overheating or too low temperature will lead to inconsistent reaction rates, causing the experimental data to deviate from the true value and affecting the reliability of the results. Then, since there are multiple placement slots on the turntable, the samples filled with liquid are placed in the multiple placement slots in sequence. During stirring, due to the large variety of sample types and different densities of each sample, the resistance received by the stirring blades is also different during stirring. If the stirring blades are not adjusted, the connections of the stirring blades will be damaged. Summary of the Invention

[0004] The purpose of the present invention is to provide a homogenizing device for medical testing with a temperature control function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The homogenizing device includes a storage component and a stirring component. A cover component is provided at the bottom end of the stirring component. The cover component is used to keep the sample in a closed environment. A heating component is provided inside the cover component for heating the sample inside the cover. A cleaning component is also provided inside the cover component. A detection component is provided at the output end of the stirring component.

[0007] Specifically, during the use of the homogenizing device, due to the liquid being stirred and shaken, the overall temperature of the liquid cannot be evenly heated, resulting in local temperature differences, which will affect the stability of the liquid components, reduce the uniformity of the liquid, and the uneven temperature may cause changes in the growth environment of microorganisms in the liquid, accelerating the reproduction of microorganisms in some areas. The storage component is used to place the sample and drive the sample to rotate, facilitating the user to place the sample. The number of the cover components is the same as the number of the placement grooves on the storage component. The cover components are mainly used to keep the sample in a closed environment, thereby preventing external contamination of the sample, improving the heating effect, and preventing heat dissipation. The heating component is used to heat the sample in the cover. The cleaning component is used to clean the inner wall of the cover to improve the environmental cleanliness and prevent the external environment from affecting the sample. The stirring component is used to stir the sample. The detection component is used to detect the temperature of the sample and control the operation of the heating component.

[0008] The storage component includes a base and a main rotating disk. The main rotating disk is provided on the upper surface of the base, and the main rotating disk is rotatably connected to the base. A main rotating motor is provided at the bottom end of the main rotating disk, and the fixed end of the main rotating motor is fixedly connected to the inner wall of the base, and the output end of the main rotating motor is fixedly connected to the bottom end of the main rotating disk.

[0009] Specifically, the base serves as the device chassis. A groove is provided on the upper surface of the base. The main rotating disk is located on the upper surface of the base and is rotatably connected to the base. A main rotating motor is provided inside the base, and the main rotating motor serves as a power source to control the rotation of the main rotating disk.

[0010] The stirring component includes a support column and a top plate. The bottom end of the support column is fixedly connected to the upper surface of the base. The top plate is provided at the top end of the support column, and the top plate is fixedly connected to the support column. A secondary rotating disk is provided at the bottom end of the top plate. A pushing motor is provided at the top end of the top plate. A connecting block is provided at the output end of the pushing motor. A secondary rotating motor is provided on one side of the connecting block. The fixed end of the secondary rotating motor is fixedly connected to the connecting block, and the output end of the secondary rotating motor is fixedly connected to the secondary rotating disk. The secondary rotating disk is rotatably connected to the connecting block. A plurality of stirring members are provided at the bottom end of the secondary rotating disk. An adjustment component is provided inside the stirring member, and the adjustment component is used to adjust the angle of the stirring blades of the stirring member.

[0011] Specifically, the stirring assembly is used to stir the samples on the main rotating disk. The support column serves as a support member to support the top plate. The pushing motor is used to control the up and down movement of the secondary rotating disk, so that the stirring member on the secondary rotating disk contacts the sample. The pushing motor serves as a power source to control the movement of the connecting block. The connecting block drives the secondary rotating motor to move. The secondary rotating motor drives the secondary rotating disk to move. The secondary rotating disk drives the stirring member to move. The secondary rotating motor serves as a power source to control the rotation of the secondary rotating disk. The secondary rotating disk drives the stirring member to rotate. Since there are many types of medical liquids and the density of each liquid is different, and the stirring blades are all fixed, the stirring efficiency is limited. Moreover, due to the fixed angle of the stirring blades, they will be subjected to greater stress or wear, shortening the service life of the stirring blades.

[0012] The stirring member includes a fixed cylinder and a first driving motor. The fixed end of the first driving motor is located inside the secondary rotating disk. The fixed end of the first driving motor is fixedly connected to the inner wall of the secondary rotating disk. The output end of the first driving motor is connected to the fixed cylinder. The adjusting assembly includes a moving block and a main electrode plate. A groove is opened at the bottom end of the fixed cylinder. The moving block is located in the groove. The moving block is slidably connected to the inner wall of the fixed cylinder. The main electrode plate is provided on the inner wall of the groove. Another main electrode plate is provided on the side of the moving block close to the groove. A spring is provided between the two main electrode plates.

[0013] Specifically, the stirring member is composed of a fixed cylinder, a movable cylinder and stirring blades, and is controlled to rotate by a first driving motor. The output end of the first driving motor is fixedly connected to the top end of the fixed cylinder. The first driving motor serves as a power source to control the rotation of the fixed cylinder. The fixed cylinder drives the movable cylinder to rotate. The movable cylinder drives the stirring blades to rotate to achieve the stirring effect. Before stirring, it is necessary to push the stirring member into the sample by the pushing motor. When the bottom end of the stirring blade touches the liquid, the moving block will be blocked and move upward. The distance between the two main electrode plates will be shortened. The change in the distance between the two main electrode plates will cause the capacitance value to change. The capacitance is inversely proportional to the distance between the plates. When the distance between the two main electrode plates increases, the capacitance will decrease; conversely, when the distance decreases, the capacitance increases. Thus, the moving distance of the moving block can be known according to the capacitance value. The spring is used to provide a reaction force. The liquid density can be obtained according to the moving distance of the moving block. The liquid density is proportional to the moving distance of the moving block.

[0014] A blade is sleeved on the fixed cylinder. The blade is slidably connected to the fixed cylinder. A cavity is opened in the fixed cylinder. A secondary electrode plate is provided at the bottom middle of the blade. Another secondary electrode plate is provided at the bottom end of the cavity. An activity cylinder is provided at the bottom end of the fixed cylinder. Stirring blades are provided on the outer wall of the activity cylinder. The stirring blades are rotatably connected to the activity cylinder. A second driving motor is provided at the connection of the stirring blades. The fixed end of the second driving motor is fixedly connected to the outer wall of the fixed cylinder. The output end of the second driving motor is connected to the stirring blades. A magnet is provided at the top end of the activity cylinder. An electromagnetic block is provided between the magnet and the blade. A resistance block is provided between the stirring blades. The two ends of the resistance block are fixedly connected to the stirring blades.

[0015] Specifically, when the stirring member enters the liquid, its blades will be blocked by the surface tension of the liquid and remain on the liquid surface. After the blades move, the distance between its two sub-electrode plates will change, and the capacitance value of the two sub-electrode plates will also change. The capacitance is inversely proportional to the distance between the plates. The liquid level can be known according to the changed value. Since the blades will remain on the liquid surface, the blades will not affect the movable cylinder. Then the movable cylinder is slidably connected to the fixed cylinder, and the position of the movable cylinder is controlled by a magnet and an electromagnet block. Then the second drive motor is used as a power source to control the angle change of the stirring blade. The resistance value generated by the resistance block is used to judge the resistance received by the stirring blade, and the angle of the stirring blade is changed by the second drive motor. Both ends of the resistance block are electrically connected to an external power supply. During stirring, the stirring blade will be resisted by the liquid pressure, which ultimately affects the resistance block. When the resistance block is pressed, it will cause the movement of internal electrons, thereby changing the resistivity, and its resistance value is proportional to the pressure received.

[0016] The cover assembly includes a cover shell and a bearing. The cover shell is sleeved on the fixed cylinder. A bearing is provided at the top of the cover shell. The outer wall of the bearing is fixedly connected to the cover shell, and the inner wall of the bearing is fixedly connected to the fixed cylinder.

[0017] Specifically, the cover assembly is used to keep the sample in a closed environment. Its driving motor will push the sub-rotating disk and also push the cover shell. Also, since the cover shell is connected to the fixed cylinder through a bearing, when the fixed cylinder rotates, it will not drive the cover shell to rotate. The bottom end of the cover shell is matched with the placement groove on the main rotating disk.

[0018] The heating assembly includes a heating tube and a heating wire. The heating tube is located on the inner wall of the cover shell and is fixedly connected to the cover shell. The heating wire is provided inside the heating tube, and there are several heating tubes.

[0019] Specifically, the heating assembly is used to heat the sample. Since the sample is placed in the cover shell, after the heating wire is powered on, heat is generated due to the high resistance, and the generated heat will accumulate in the cover shell. The heating tube has high mechanical strength and can withstand a certain amount of pressure and mechanical vibration.

[0020] The cleaning assembly includes a nozzle and a collection bin. The nozzle is located inside the cover shell. The fixed end of the nozzle is fixedly connected to the inner wall of the cover shell. The input end of the nozzle is connected to an external pipeline. The collection bin is located at the bottom end of the main rotating disk, and through holes for liquid are provided on the main rotating disk.

[0021] Specifically, the cleaning assembly is used to clean the cover shell after the stirring process to ensure the cleanliness inside the cover shell. The nozzle is obliquely installed inside the cover shell, and the output end of the nozzle is aligned with the top end inside the cover shell. The cleaning liquid will flow into the collection bin through the through holes for liquid on the main rotating disk. The input end of the nozzle is connected to an external pipeline, and the external pipeline is used to provide the cleaning liquid.

[0022] The detection component includes a thermistor and leads. The thermistor is located at the bottom end of the fixed cylinder, and the thermistor is fixedly connected to the fixed cylinder. Leads are provided at both ends of the thermistor.

[0023] Specifically, the detection component is used to detect the temperature of the liquid in the sample. Since the sample is heated inside the housing, the housing ensures that heat does not disperse, thus ensuring uniform overall heating. Its thermistor is used to detect the liquid temperature. When the temperature rises, the number of carriers in the semiconductor material increases, resulting in a decrease in the resistance value; conversely, when the temperature drops, the number of carriers decreases and the resistance value increases. The change in the resistance value represents the change in the liquid temperature. The leads are used to connect to the external circuit for temperature measurement and signal transmission.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. When the stirring member enters the liquid, its blades will be blocked by the liquid surface tension and remain on the liquid surface. After the blades move, the distance between its two sub-electrode plates will change. The liquid level can be known according to the changed value, and then the movable cylinder is controlled to move up and down through the magnet and the electromagnet block, so that when stirring, the stirring blades move up and down, which can make all parts of the liquid be fully mixed, effectively avoid stirring dead corners, and improve the uniformity of homogenization.

[0026] 2. The housing of the present invention is used to make the sample in a closed environment, so that the housing ensures that heat does not disperse during heating, thus ensuring uniform overall heating. Then, the temperature of the sample is detected by the thermistor, and the heating wire is controlled to be energized according to the detection result. And during the heating process, due to the up and down movement of the movable cylinder, the heating uniformity is also effectively improved.

[0027] 3. When stirring, the stirring blades will generate resistance due to the liquid pressure, which will ultimately affect the resistance block. When the resistance block is pressed, it will cause the movement of internal electrons, thereby changing the resistivity. Its resistance value is proportional to the pressure received. The resistance value generated by the resistance block is used to judge the resistance received by the stirring blades, and the angle of the stirring blades is changed through the second drive motor. Changing the angle of the stirring blades can adjust the flow pattern of the liquid. When dealing with low-viscosity liquids, appropriately increasing the angle of the stirring blades can make the liquid generate more complex flow trajectories, promote the full intersection and mixing of all parts of the liquid, and reduce the mixing dead corners.

[0028] 4. Since the housing wraps the sample, it ensures the environment where the sample is located during stirring, preventing external contamination of the sample. Because the bottle mouth is at the upper end, the liquid may splash into the housing during stirring. Its nozzle is used to clean the inside of the housing, and the cleaning liquid will flow through the liquid through-hole to the collection bin, facilitating the collection of waste liquid.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment:

[0041] As Figures 1 to 9As shown in the figure, the present invention provides a technical solution for a homogenizing device for medical tests with a temperature control function. The homogenizing device includes a storage component 1 and a stirring component 2. A cover component 3 is provided at the bottom end of the stirring component 2. The cover component 3 is used to keep the sample in a closed environment. A heating component 4 is provided inside the cover component 3. The heating component 4 is used to heat the sample inside the cover. A cleaning component 5 is also provided inside the cover component 3. A detection component 6 is provided at the output end of the stirring component 2.

[0042] Specifically, during the use of the homogenizing device, due to the shaking of the liquid caused by stirring, the overall temperature of the liquid cannot be evenly heated, resulting in local temperature differences, affecting the stability of the liquid components and reducing the liquid uniformity. The uneven temperature may cause changes in the growth environment of microorganisms in the liquid, accelerating the reproduction of microorganisms in some areas. The storage component 1 is used to place the sample and drive the sample to rotate, facilitating the user to place the sample. The number of cover components 3 is the same as the placement slots on the storage component 1. The cover component 3 is mainly used to keep the sample in a closed environment, thereby preventing external contamination of the sample and also improving the heating effect and preventing heat dissipation. The heating component 4 is used to heat the sample inside the cover, and the cleaning component 5 is used to clean the inner wall of the cover to improve the environmental cleanliness and prevent the external environment from affecting the sample. The stirring component 2 is used to stir the sample, and the detection component 6 is used to detect the temperature of the sample and control the operation of the heating component 4.

[0043] As Figures 1 to 3 shown in the figure, the storage component 1 includes a base 11 and a main rotating disk 12. The main rotating disk 12 is provided on the upper surface of the base 11. The main rotating disk 12 is rotatably connected to the base 11. A main rotating motor 13 is provided at the bottom end of the main rotating disk 12. The fixed end of the main rotating motor 13 is fixedly connected to the inner wall of the base 11, and the output end of the main rotating motor 13 is fixedly connected to the bottom end of the main rotating disk 12.

[0044] Specifically, the base 11 serves as the device chassis. A groove is provided on the upper surface of the base 11. The main rotating disk 12 is located on the upper surface of the base 11 and is rotatably connected to the base 11. A main rotating motor 13 is provided inside the base 11. The main rotating motor 13 serves as a power source to control the rotation of the main rotating disk 12.

[0045] As Figures 1 to 3As shown, the stirring assembly 2 includes a support column 21 and a top plate 23. The bottom end of the support column 21 is fixedly connected to the upper surface of the base 11. The top end of the support column 21 is provided with a top plate 23, and the top plate 23 is fixedly connected to the support column 21. The bottom end of the top plate 23 is provided with a secondary rotating disk 24, and the top end of the top plate 23 is provided with a pushing motor 25. The output end of the pushing motor 25 is provided with a connecting block 26. One side of the connecting block 26 is provided with a secondary rotating motor 27. The fixed end of the secondary rotating motor 27 is fixedly connected to the connecting block 26, and the output end of the secondary rotating motor 27 is fixedly connected to the secondary rotating disk 24. The secondary rotating disk 24 is rotatably connected to the connecting block 26. The bottom end of the secondary rotating disk 24 is provided with a plurality of stirring members 7, and an adjustment assembly 8 is arranged inside the stirring member 7. The adjustment assembly 8 is used to adjust the angle of the stirring blades 75 of the stirring member 7.

[0046] Specifically, the stirring assembly 2 is used to stir the samples on the main rotating disk 12. The support column 21 serves as a support member to support the top plate 23. The pushing motor 25 is used to control the up and down movement of the secondary rotating disk 24, so that the stirring members 7 on the secondary rotating disk 24 come into contact with the samples. The pushing motor 25 serves as a power source to control the movement of the connecting block 26. The connecting block 26 drives the secondary rotating motor 27 to move, the secondary rotating motor 27 drives the secondary rotating disk 24 to move, and the secondary rotating disk 24 drives the stirring members 7 to move. The secondary rotating motor 27 serves as a power source to control the rotation of the secondary rotating disk 24, and the secondary rotating disk 24 drives the stirring members 7 to rotate. Since there are many types of medical liquids and the density of each liquid is different, and the stirring blades 75 are all fixed, the stirring efficiency is limited. Moreover, due to the fixed angle of the stirring blades 75, they will be subjected to greater stress or wear, shortening the service life of the stirring blades 75.

[0047] As Figures 4 to 8 As shown, the stirring member 7 includes a fixed cylinder 71 and a first driving motor 72. The fixed end of the first driving motor 72 is located inside the secondary rotating disk 24, and the fixed end of the first driving motor 72 is fixedly connected to the inner wall of the secondary rotating disk 24. The output end of the first driving motor 72 is connected to the fixed cylinder 71. The adjustment assembly 8 includes a moving block 81 and a main electrode plate 82. A groove 711 is opened at the bottom end of the fixed cylinder 71. The moving block 81 is located inside the groove 711, and the moving block 81 is slidably connected to the inner wall of the fixed cylinder 71. The main electrode plate 82 is arranged on the inner wall of the groove 711. Another main electrode plate 82 is arranged on the side of the moving block 81 close to the groove 711, and a spring 83 is arranged between the two main electrode plates 82.

[0048] Specifically, the stirring member 7 is composed of a fixed cylinder 71, a movable cylinder 74 and stirring blades 75, and is controlled to rotate by a first driving motor 72. The output end of the first driving motor 72 is fixedly connected to the top end of the fixed cylinder 71. The first driving motor 72 serves as a power source to control the rotation of the fixed cylinder 71. The fixed cylinder 71 drives the movable cylinder 74 to rotate, and the movable cylinder 74 drives the stirring blades 75 to rotate to achieve the stirring effect. Before stirring, the stirring member 7 needs to be pushed into the sample by a pushing motor 25. When the bottom end of the stirring blade 75 touches the liquid, the moving block 81 will be blocked and move upward, and the distance between its two main electrode plates 82 will be shortened. The change in the distance between the two main electrode plates 82 will cause a change in the capacitance value. The capacitance is inversely proportional to the distance between the plates. When the distance between the two main electrode plates 82 increases, the capacitance will decrease; conversely, when the distance decreases, the capacitance increases. Thus, the moving distance of the moving block 81 can be known according to the capacitance value. The spring 83 is used to provide a reaction force, and the liquid density can be obtained according to the moving distance of the moving block 81. The liquid density is proportional to the moving distance of the moving block 81.

[0049] As Figures 4 to 8 shown, a blade 73 is sleeved on the fixed cylinder 71. The blade 73 is slidably connected to the fixed cylinder 71. A cavity 712 is formed in the fixed cylinder 71. A secondary electrode plate 84 is provided at the bottom end in the middle of the blade 73, and another secondary electrode plate 84 is provided at the bottom end of the cavity 712. The movable cylinder 74 is provided at the bottom end of the fixed cylinder 71. Stirring blades 75 are provided on the outer wall of the movable cylinder 74. The stirring blades 75 are rotatably connected to the movable cylinder 74. A second driving motor 76 is provided at the connection part of the stirring blades 75. The fixed end of the second driving motor 76 is fixedly connected to the outer wall of the fixed cylinder 71, and the output end of the second driving motor 76 is connected to the stirring blades 75. A magnet 77 is provided at the top end of the movable cylinder 74. An electromagnetic block 78 is provided between the magnet 77 and the blade 73. A resistance block 79 is provided between the stirring blades 75. Both ends of the resistance block 79 are fixedly connected to the stirring blades 75, and both ends of the resistance block 79 are electrically connected to an external power source. Thus, during stirring, the stirring blades 75 will generate resistance under the liquid pressure, which will ultimately affect the resistance block 79. When the resistance block 79 is pressed, it will cause the movement of internal electrons, thereby changing the resistivity. Its resistance value is proportional to the pressure received.

[0050] Specifically, when the stirring member 7 enters the liquid, its blades 73 will be blocked by the surface tension of the liquid and remain on the liquid surface. After the blades 73 move, the distance between the two sub-electrode plates 84 will change, and the capacitance value of the two sub-electrode plates 84 will also change. The capacitance is inversely proportional to the distance between the plates. The liquid level can be known according to the changed numerical value. Since the blades 73 will remain on the liquid surface, the blades 73 will not affect the movable cylinder 74. Then, the movable cylinder 74 is slidably connected to the fixed cylinder 71, and the position of the movable cylinder 74 is controlled by a magnet 77 and an electromagnet 78. Then, the second drive motor 76 is used as a power source to control the angle change of the stirring blade 75. The resistance value generated by the resistance block 79 is used to know the resistance received by the stirring blade 75, and the angle of the stirring blade 75 is changed by the second drive motor 76.

[0051] As Figure 4 , Figure 5 shown, the cover assembly 3 includes a cover shell 31 and a bearing 32. The cover shell 31 is sleeved on the fixed cylinder 71. A bearing 32 is provided at the top of the cover shell 31. The outer wall of the bearing 32 is fixedly connected to the cover shell 31, and the inner wall of the bearing 32 is fixedly connected to the fixed cylinder 71.

[0052] Specifically, the cover assembly 3 is used to keep the sample in a closed environment. Its driving motor 25 will push the main rotating disk 12 and also push the cover shell 31. Also, since the cover shell 31 is connected to the fixed cylinder 71 through the bearing 32, when the fixed cylinder 71 rotates, it will not drive the cover shell 31 to rotate. The bottom end of the cover shell 31 is matched with the placement groove on the sub-rotating disk 24.

[0053] As Figure 4 , Figure 5 shown, the heating assembly 4 includes a heating tube 41 and a heating wire 42. The heating tube 41 is located on the inner wall of the cover shell 31. The heating tube 41 is fixedly connected to the cover shell 31. A heating wire 42 is provided inside the heating tube 41, and there are several heating tubes 41.

[0054] Specifically, the heating assembly 4 is used to heat the sample. Since the sample is placed in the cover shell 31, after the heating wire 42 is powered on, heat is generated due to high resistance, and the generated heat will accumulate in the cover shell 31. The heating tube 41 has high mechanical strength and can withstand a certain amount of pressure and mechanical vibration.

[0055] As Figure 5 , Figure 9 shown, the cleaning assembly 5 includes a nozzle 51 and a collection bin 52. The nozzle 51 is located inside the cover shell 31. The fixed end of the nozzle 51 is fixedly connected to the inner wall of the cover shell 31. The input end of the nozzle 51 is connected to an external pipeline. The collection bin 52 is located at the bottom end of the main rotating disk 12, and liquid passing holes are provided on the main rotating disk 12.

[0056] Specifically, the cleaning component 5 is used to clean the housing 31 after the stirring process to ensure the cleanliness inside the housing 31. The nozzle 51 is obliquely installed in the housing 31, and the output end of the nozzle 51 is aligned with the top end inside the housing 31. The cleaning liquid will flow into the collection bin 52 through the liquid passage holes on the main rotating disk 12. The input end of the nozzle 51 is connected to an external pipeline, and the external pipeline is used to supply the cleaning liquid.

[0057] As Figure 6 shown, the detection component 6 includes a thermistor 61 and leads 62. The thermistor 61 is located at the bottom end of the fixed cylinder 71, and the thermistor 61 is fixedly connected to the fixed cylinder 71. Leads 62 are provided at both ends of the thermistor 61.

[0058] Specifically, the detection component 6 is used to detect the liquid temperature in the sample. Since the sample is heated inside the housing 31, the housing 31 ensures that the heat does not disperse, thus ensuring uniform overall heating. The thermistor 61 is used to detect the liquid temperature. When the temperature rises, the number of carriers in the semiconductor material increases, resulting in a decrease in the resistance value; conversely, when the temperature drops, the number of carriers decreases and the resistance value increases. The change in the resistance value represents the change in the liquid temperature. The leads 62 are used to connect to an external circuit for temperature measurement and signal transmission.

[0059] Working principle: During use, the staff first place the sample on the main rotating disk 12. The main rotating disk 12 rotates through the main rotating motor 13, which is convenient for placing the sample. Before the stirring process, the pushing motor 25 serves as a power source to control the movement of the connecting block 26. The connecting block 26 drives the movement of the auxiliary rotating motor 27. The auxiliary rotating motor 27 drives the movement of the auxiliary rotating disk 24. The auxiliary rotating disk 24 drives the stirring member 7 to move, so that the stirring member 7 contacts the liquid in the sample. During this period, the auxiliary rotating motor 27 serves as a power source to control the rotation of the auxiliary rotating disk 24. The auxiliary rotating disk 24 drives the stirring member 7 to rotate, so that the stirring member 7 and the auxiliary rotating disk 24 are on the same central axis. When the bottom end of the stirring member 7 touches the liquid, the moving block 81 will be blocked and move upward, and the distance between its two main electrode plates 82 will be shortened. The change in the distance between the two main electrode plates 82 will cause a change in the capacitance value, so as to know the moving distance of the moving block 81 according to the size of the capacitance value. The spring 83 is used to provide a reaction force. The liquid density is obtained according to the moving distance of the moving block 81. The liquid density is proportional to the moving distance of the moving block 81. The second driving motor 76 is controlled to work by detecting the liquid density to change the angle of the stirring blade 75. Then its blade 73 will be blocked by the liquid surface tension and stay on the liquid surface. After the blade 73 moves, the distance between its two auxiliary electrode plates 84 will change, and the capacitance value of the two auxiliary electrode plates 84 will also change. The liquid level is known according to the changed value, and the blade 73 will stay on the liquid surface, and the blade 73 will not affect the movable cylinder 74. The electromagnetic block 78 and the magnet 77 work through the capacitance value of the auxiliary electrode plate 84 to make the movable cylinder 74 in the middle of the liquid and control the up and down movement of the movable cylinder 74 in the subsequent stirring process. Through the two, the stirring member 7 is suitable for samples of different liquids. Then, when the stirring process is carried out, the rotation of the stirring blade 75 will generate resistance due to the liquid pressure, which will ultimately affect the resistance block 79. When the resistance block 79 is pressed, it will cause the movement of internal electrons, thereby changing the resistivity. Its resistance value is proportional to the pressure received. The resistance generated by the resistance block 79 is used to judge the resistance received by the stirring blade 75. Finally, the angle of the stirring blade 75 is adjusted according to the resistance value and the liquid density during stirring. When dealing with low-viscosity liquids, appropriately increasing the angle of the stirring blade 75 can make the liquid generate more complex flow trajectories, promote the full intersection and mixing of each part of the liquid, and reduce the mixing dead angle. When dealing with high-viscosity liquids, appropriately reducing the angle of the stirring blade 75 makes the stirring blade 75 receive less resistance. After the stirring process, the pushing motor 25 controls the auxiliary rotating disk 24 to move upward, and the staff takes out the sample. The pushing motor 25 controls the auxiliary rotating disk 24 to move downward, so that the cover 31 meshes with the placement groove on the main rotating disk 12. At this time, the nozzle 51 sprays the cleaning liquid, and the cleaning liquid will flow through the liquid through hole to the collection bin 52, which is convenient for collecting the waste liquid. Thus, the cover 31 not only prevents the temperature from spreading, but also ensures the environment where the sample is located during stirring, and prevents the outside from contaminating the sample because the bottle mouth is at the upper end.
