Description

Technical Field

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

[0002] Homogenizer, also called adjustable high-speed homogenizer, is a routine equipment used for scientific research institutions and medical and epidemic prevention stations and hospitals for inspection. The homogenizer can crush, homogenize, emulsify, disperse, vigorously stir, warm, and dissolve organic or inorganic substances. It is characterized by stable performance, compact structure, beautiful appearance, easy use, safety and reliability, and extremely high work efficiency.

[0003] The existing homogenization device needs to heat the sample during use, but there will be uneven temperature. Local overheating or 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, because there are multiple placement slots on the turntable, the samples containing liquid are placed in multiple placement slots in turn. During stirring, due to the large number of sample types and the different density of each sample, the resistance encountered by the stirring blade is also different during stirring. If the stirring blade is not adjusted, the connection of the stirring blade will be damaged. Summary of the Invention

[0004] The object 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 object, the present invention provides the following technical solutions:

[0006] The homogenization device includes a storage component and a stirring component. A cover component is provided at the bottom of the stirring component. The cover component is used to place the sample in a closed environment. A heating component is provided inside the cover component. The heating component is used to heat 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, when the homogenizer is in use, the liquid shakes due to stirring, and the overall temperature of the liquid cannot be heated evenly, which will cause local temperature differences, affect the stability of the liquid components, and reduce the uniformity of the liquid. The uneven temperature may cause the growth environment of microorganisms in the liquid to change, causing the microorganisms to reproduce faster in certain areas. The storage component is used to place samples and drive the samples to rotate, so that users can place samples conveniently. The number of cover components is the same as the placement slots on the storage component. The cover component is mainly used to place the sample in a closed environment, thereby preventing the outside world from contaminating the sample. It also increases the heating effect and prevents heat loss. 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 cleanliness of the environment 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 assembly 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. 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 chassis of the device, a groove is provided on the upper surface of the base, the main rotating disk is located on the upper surface of the base, the main rotating disk 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 for controlling the rotation of the main rotating disk.

[0010] The stirring assembly 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, a top plate is provided on the top of the support column, 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 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, 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 number of stirring members are provided at the bottom end of the secondary rotating disk, an adjustment member is provided in the stirring member, and the adjustment member is used to adjust the angle of the stirring blade of the stirring member.

[0011] Specifically, the stirring assembly is used to stir the sample on the main rotating disk, the support column serves as a support member for supporting the top plate, the push motor is used to control the up and down movement of the sub-rotating disk so that the stirring member on the sub-rotating disk contacts the sample, the push motor serves as a power source to control the movement of the connecting block, the connecting block drives the sub-rotating motor to move, the sub-rotating motor drives the sub-rotating disk to move, the sub-rotating disk drives the stirring member to move, the sub-rotating motor serves as a power source to control the rotation of the sub-rotating disk, the sub-rotating disk drives the stirring member to rotate, because there are many types of medical liquids, the density of each liquid is different, and the stirring blades are fixed, its stirring efficiency is limited, and because the stirring blades are fixed at an angle, 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 drive motor. The fixed end of the first drive motor is located in the auxiliary rotating disk. The fixed end of the first drive motor is fixedly connected to the inner wall of the auxiliary rotating disk. The output end of the first drive motor is connected to the fixed cylinder. The adjustment component includes a moving block and a main electrode plate. A groove is provided 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 inner wall of the groove is provided with a main electrode plate. 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 element is composed of a fixed cylinder, a movable cylinder and a stirring blade, and is controlled to rotate by a first drive motor. The output end of the first drive motor is fixedly connected to the top end of the fixed cylinder. The first drive motor is used as a power source to control the rotation of the fixed cylinder. The fixed cylinder drives the movable cylinder to rotate, and the movable cylinder drives the stirring blade to rotate to achieve a stirring effect. Before stirring, the stirring element needs to be pushed into the sample by pushing the motor. When the bottom end of the stirring blade contacts the liquid, the moving block will be hindered from moving upward, and the distance between its 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 size of 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. The moving distance of the moving block is known according to the capacitance value. The spring is used to provide reverse thrust. The liquid density is obtained according to the moving distance of the moving block, and the liquid density is proportional to the moving distance of the moving block.

[0014] The fixed cylinder is provided with blades, which are slidably connected to the fixed cylinder. A cavity is opened in the fixed cylinder, a secondary electrode plate is provided at the middle bottom end of the blade, and another secondary electrode plate is provided at the bottom end of the cavity. A movable cylinder is provided at the bottom end of the fixed cylinder, and a stirring blade is provided on the outer wall of the movable cylinder. The stirring blade is rotatably connected to the movable cylinder. A second drive motor is provided at the connection of the stirring blade, and the fixed end of the second drive motor is fixedly connected to the outer wall of the fixed cylinder. The output end of the second drive motor is connected to the stirring blade. A magnet is provided at the top of the movable cylinder, an electromagnetic block is provided between the magnet and the blade, a resistance block is provided between the stirring blades, and both ends of the resistance block are fixedly connected to the stirring blade.

[0015] Specifically, when the stirring element enters the liquid, its blades will remain on the surface of the liquid due to the obstruction of the surface tension of the liquid. After the blades move, the distance between the two secondary electrode plates will change, and the capacitance value of the two secondary electrode plates will also change. The size of the capacitance is inversely proportional to the distance between the plates. The liquid level is known according to the changed value. Because the blades will remain on the surface of the liquid, the blades will not affect the movable cylinder. Then the movable cylinder is slidably connected to the fixed cylinder. The position of the movable cylinder is controlled by the magnet and the electromagnetic block. Then the second drive motor is used as a power source to control the angle change of the stirring blade. The resistance of the stirring blade is judged according to the resistance value generated by the resistance block, and the angle of the stirring blade is changed by the second drive motor. The two ends of the resistance block are electrically connected to the external power supply. During stirring, the stirring blade will generate resistance due to the liquid pressure, which will eventually affect the resistance block. When the resistance block is under pressure, it will cause the movement of internal electrons, thereby changing the resistivity. Its resistance value is proportional to the pressure.

[0016] The cover assembly includes a cover shell and a bearing. The cover shell is sleeved on the fixed cylinder. A bearing is provided on 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 place the sample in a closed environment. Its driving motor will drive the secondary rotating disk and also push the cover shell. Because the cover shell is connected to the fixed cylinder through a bearing, the rotation of the fixed cylinder will not drive the cover shell to rotate. The bottom end of the cover shell cooperates with the placement slot on the main rotating disk.

[0018] The heating component 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 arranged in the heating tube. There are several heating tubes.

[0019] Specifically, the heating component is used to heat the sample. Because the sample is placed in the cover, when the heating wire is energized, heat is generated due to the high resistance, and the generated heat will accumulate in the cover. The heating tube has high mechanical strength and can withstand certain pressure and mechanical vibration.

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

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

[0022] The detection component includes a thermistor and a lead. The thermistor is located at the bottom end of the fixed cylinder, the thermistor is fixedly connected to the fixed cylinder, and lead wires 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 in a cover, the cover ensures that the heat will not dissipate, thereby ensuring uniform heating of the whole. Its thermistor is used to detect the temperature of the liquid. When the temperature rises, the number of carriers in the semiconductor material increases, resulting in a decrease in resistance value; conversely, when the temperature drops, the number of carriers decreases and the resistance value increases. The change in resistance value represents the change in liquid temperature. The leads are used to connect to external circuits for temperature measurement and signal transmission.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the present invention, when the stirring element enters the liquid, its blades will remain on the surface of the liquid due to the obstruction of the surface tension of the liquid. After the blades move, the distance between the two secondary electrode plates will change. The liquid level is known according to the changed value. Then, the movable cylinder is controlled to move up and down by the magnet and the electromagnetic block. During stirring, the stirring blades can move up and down, which can fully mix the various parts of the liquid, effectively avoid dead corners in stirring, and improve the uniformity of the homogenate.

[0026] 2. The cover of the present invention is used to place the sample in a closed environment, so that the cover ensures that the heat will not disperse during heating, thereby ensuring overall uniform heating. Then, the temperature of the sample is detected by the thermistor, and the heating wire is energized according to the detection result. In addition, during the heating process, the up and down movement of the movable cylinder can also effectively improve the uniformity of heating.

[0027] 3. When stirring, the present invention generates resistance on the stirring blade due to the liquid pressure, which eventually affects the resistor block. When the resistor block is under pressure, it will cause the movement of internal electrons, thereby changing the resistivity. The resistance value is proportional to the pressure. The resistance of the stirring blade is judged according to the resistance value generated by the resistor block, and the angle of the stirring blade is changed by the second drive motor. Changing the angle of the stirring blade can adjust the flow pattern of the liquid. When processing low-viscosity liquids, appropriately increasing the angle of the stirring blade can make the liquid produce a more complex flow trajectory, promote the full intersection and mixing of the various parts of the liquid, and reduce mixing dead angles.

[0028] 4. The present invention wraps the sample in the cover to ensure the environment of the sample during stirring, thereby preventing the sample from being contaminated by the outside world. Because the bottle mouth is at the upper end, the liquid is likely to splash into the cover during stirring. The nozzle is used to clean the inside of the cover, and the cleaning liquid will flow to the collection bin through the liquid hole, which is convenient for collecting waste liquid.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0040] Example:

[0041] like Figures 1 to 9As shown, the present invention provides a technical solution for a homogenizing device for medical testing with a temperature control function.

A cleaning component 5 is also provided in the cover component 3. A detection component 6 is provided at the output end of the stirring component 2.

[0042] Specifically, when the homogenizer is in use, the liquid shakes due to stirring, and the overall temperature of the liquid cannot be heated evenly, which will cause local temperature differences, affect the stability of the liquid components, and reduce the uniformity of the liquid. The uneven temperature may cause the growth environment of microorganisms in the liquid to change, causing the microorganisms to reproduce faster in certain areas. The storage component 1 is used to place samples and drive the samples to rotate, which is convenient for users to place samples. 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 place the sample in a closed environment, thereby preventing the outside world from contaminating the sample, and also increasing the heating effect to prevent heat loss. The heating component 4 is used to heat the sample in the cover body, and the cleaning component 5 is used to clean the inner wall of the cover body to improve the cleanliness of the environment 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] like Figures 1 to 3 As shown, the storage assembly 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, and 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, and 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 chassis of the device, 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, the main rotating disk 12 is rotatably connected to the base 11, and a main rotating motor 13 is provided inside the base 11. The main rotating motor 13 serves as a power source for controlling the rotation of the main rotating disk 12.

[0045] like 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. A top plate 23 is provided at the top of the support column 21. The top plate 23 is fixedly connected to the support column 21. A secondary rotating disk 24 is provided at the bottom end of the top plate 23. A pushing motor 25 is provided at the top of the top plate 23. A connecting block 26 is provided at the output end of the pushing motor 25. A secondary rotating motor 27 is provided on one side of the connecting block 26. The fixed end of the secondary rotating motor 27 is fixedly connected to the connecting block 26. 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. A number of stirring members 7 are provided at the bottom end of the stirring member 7. An adjustment assembly 8 is provided in the stirring member 7. The adjustment assembly 8 is used to adjust the angle of the stirring blade 75 of the stirring member 7.

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

[0047] like Figures 4 to 8 As shown, the stirring member 7 includes a fixed cylinder 71 and a first drive motor 72. The fixed end of the first drive motor 72 is located in the auxiliary rotating disk 24. The fixed end of the first drive motor 72 is fixedly connected to the inner wall of the auxiliary rotating disk 24. The output end of the first drive motor 72 is connected to the fixed cylinder 71. The adjustment component 8 includes a moving block 81 and a main electrode plate 82. A groove 711 is provided at the bottom end of the fixed cylinder 71. The moving block 81 is located in the groove 711. The moving block 81 is slidably connected to the inner wall of the fixed cylinder 71. The inner wall of the groove 711 is provided with a main electrode plate 82. Another main electrode plate 82 is provided on the side of the moving block 81 close to the groove 711. A spring 83 is provided 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 a stirring blade 75, and is controlled to rotate by a first drive motor 72. The output end of the first drive motor 72 is fixedly connected to the top of the fixed cylinder 71. The first drive 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 blade 75 to rotate to achieve a stirring effect. Before stirring, it is necessary to push the stirring member 7 into the sample by pushing the motor 25. When the bottom end of the stirring blade 75 contacts the liquid, the moving block 81 will be blocked from moving 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 the capacitance value to change. The size of the capacitance is inversely proportional to the distance between the plates. When the distance between the two main electrode plates 82 increases, the capacitance decreases; conversely, when the distance decreases, the capacitance increases. The moving distance of the moving block 81 is known according to the capacitance value. The spring 83 is used to provide a reverse thrust. The liquid density is obtained according to the moving distance of the moving block 81, and the liquid density is proportional to the moving distance of the moving block 81.

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

[0050] Specifically, when the stirring element 7 enters the liquid, its blade 73 will remain on the surface of the liquid due to the obstruction of the surface tension of the liquid. 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 size of the capacitance is inversely proportional to the distance between the plates. The liquid level is known according to the changed value. Since the blade 73 will remain on the surface of the liquid, the blade 73 will not affect the movable cylinder 74. Then the movable cylinder 74 is slidably connected to the fixed cylinder 71. The position of the movable cylinder 74 is controlled by the magnet 77 and the electromagnetic block 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 of the stirring blade 75, and the angle of the stirring blade 75 is changed by the second drive motor 76.

[0051] like Figure 4 、 Figure 5 As 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. The bearing 32 is provided on 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 place the sample in a closed environment. Its driving motor 25 will drive the main rotating disk 12 and also push the cover shell 31. Since the cover shell 31 is connected to the fixed cylinder 71 through the bearing 32, the fixed cylinder 71 will not drive the cover shell 31 to rotate when it rotates. The bottom end of the cover shell 31 cooperates with the placement groove on the auxiliary rotating disk 24.

[0053] like Figure 4 、 Figure 5 As shown, the heating component 4 includes a heating tube 41 and a heating wire 42. The heating tube 41 is located on the inner wall of the cover 31. The heating tube 41 is fixedly connected to the cover 31. The heating wire 42 is provided in the heating tube 41. There are several heating tubes 41.

[0054] Specifically, the heating component 4 is used to heat the sample. Since the sample is placed in the cover 31, when the heating wire 42 is energized, heat is generated due to the high resistance, and the generated heat will accumulate in the cover 31. The heating tube 41 has high mechanical strength and can withstand certain pressure and mechanical vibration.

[0055] like Figure 5 、 Figure 9 As shown, the cleaning assembly 5 includes a nozzle 51 and a collecting bin 52. The nozzle 51 is located inside the cover 31. The fixed end of the nozzle 51 is fixedly connected to the inner wall of the cover 31. The input end of the nozzle 51 is connected to an external pipe. The collecting bin 52 is located at the bottom end of the main rotating disk 12. A liquid hole is provided on the main rotating disk 12.

[0056] Specifically, the cleaning component 5 is used to clean the cover shell 31 after the stirring process to ensure the cleanliness of the interior of the cover shell 31, wherein the nozzle 51 is installed obliquely in the cover shell 31, and the output end of the nozzle 51 is aligned with the top of the interior of the cover shell 31. The cleaning liquid will flow into the collection bin 52 through the liquid hole on the main rotating disk 12. The input end of the nozzle 51 is connected to an external pipe, and the external pipe is used to provide cleaning liquid.

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

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

[0059] Working principle: When in use, the staff will first place the sample on the main rotating disk 12, and the main rotating disk 12 is rotated by the main rotating motor 13 to facilitate sample placement. Before the stirring process, the pushing motor 25 is used as a power source to control the movement of the connecting block 26, and the connecting block 26 drives the auxiliary rotating motor 27 to move, and the auxiliary rotating motor 27 drives the auxiliary rotating disk 24 to move, and 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 is used as a power source to control the rotation of the auxiliary rotating disk 24, and 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 contacts the liquid, the moving block 81 will be blocked from moving upward, and its two The distance between the main electrode plates 82 will be shortened, and the change in the distance between the two main electrode plates 82 will cause the capacitance value to change, so that the moving distance of the moving block 81 can be known according to the capacitance value. The spring 83 is used to provide a reverse thrust, and 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. By detecting the liquid density, the second drive motor 76 is controlled to work so that the angle of the stirring blade 75 is changed, and then its blade 73 will remain on the liquid surface due to the obstruction of the liquid surface tension. After the blade 73 moves, the distance between its two secondary electrode plates 84 will change, and the capacitance value of the two secondary electrode plates 84 will also change. The liquid level can be known according to the changed value, and the blade 73 will remain on the liquid surface. The blade 73 does not It will affect the movable cylinder 74. The electromagnetic block 78 and the magnet 77 work through the capacitance value of the secondary electrode plate 84, so that the movable cylinder 74 is in the middle of the liquid and controls the movable cylinder 74 to move up and down 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 eventually affect the resistor block 79. When the resistor block 79 is pressurized, it will cause the movement of internal electrons, thereby changing the resistivity. Its resistance value is proportional to the pressure it receives. The resistance of the stirring blade 75 is judged according to the resistance value generated by the resistor block 79. Finally, the angle of the stirring blade 75 is adjusted according to the resistance value and the liquid density during stirring, so that when processing low-viscosity liquids, the angle of the stirring blade 75 can be appropriately increased. The liquid is made to have a more complex flow trajectory, which promotes the full intersection and mixing of the various parts of the liquid and reduces the mixing dead angle. When processing high-viscosity liquids, the angle of the stirring blade 75 is appropriately reduced so that the stirring blade 75 is subjected to less resistance. After the stirring process, the motor 25 is pushed to move upward on the control sub-rotating disk 24, and the staff takes out the sample and pushes the motor 25 to move downward on the control sub-rotating disk 24, so that the cover 31 is engaged with the placement groove on the main rotating disk 12. At this time, the nozzle 51 sprays out the cleaning liquid, and the cleaning liquid will flow to the collection bin 52 through the liquid hole, which is convenient for collecting the waste liquid. Therefore, the cover 31 not only prevents the temperature from dissipating, but also ensures the environment of the sample during stirring, and prevents the outside world from contaminating the sample because the bottle mouth is at the upper end.
