Description

Technical Field

[0001] This application relates to the field of pharmacological equipment, and in particular to a drug supply stirring and heating device for pharmacological purposes. Background Technology

[0002] In pharmacological research and pharmaceutical formulation production, the stirring and heating of the drug supply are key steps in achieving drug dissolution, mixing, and reaction. Stirring and heating can effectively promote the uniform dispersion of drug components in the solvent, accelerate the chemical reaction process, and improve the stability and efficacy of the pharmaceutical formulation.

[0003] Publication number CN221015698U discloses a drug feeding stirring and heating device for pharmacology, but it still has the following shortcomings in practical use:

[0004] When stirring liquids with high viscosity (such as those containing polymers or colloids), the stirring device is unable to drive the liquid to flow at the edges, causing the liquid to adhere to the cup wall due to gravity or surface tension, forming a "wall-hanging" phenomenon. This reduces the uniformity of the liquid mixing and increases the difficulty of cleaning the stirring device later. Utility Model Content

[0005] To address the issue of viscous drug solutions easily adhering to the walls during stirring, this application provides a pharmacological drug supply stirring and heating device.

[0006] The pharmacological drug supply stirring and heating device provided in this application adopts the following technical solution:

[0007] A pharmacological drug supply stirring and heating device includes a stirring tank, a sealing cap threaded to one side of the surface of the stirring tank, a heat insulation sleeve fixed to the inner wall of the stirring tank, and a multi-layer processing mechanism for stirring the drug solution and scraping off residual drug solution from the inner wall of the heat insulation sleeve inside the stirring tank.

[0008] The multi-layer processing mechanism includes a stirring shaft disposed inside a stirring tank. Multiple stirring blades for stirring the medicine liquid are fixed on the surface of the stirring shaft. A scraper for scraping off residual medicine liquid on the inner wall of the heat insulation sleeve is disposed at the end of the stirring blade away from the stirring shaft. The end of the scraper away from the stirring blade abuts against the inner wall of the heat insulation sleeve. The end of the scraper away from the stirring blade is double-sloped.

[0009] By adopting the above technical solution, the liquid medicine inside the heat insulation sleeve is stirred by a multi-layer processing mechanism, and the liquid medicine adhering to the inner wall of the heat insulation sleeve is scraped off during the stirring process, so that the liquid medicine is evenly mixed.

A drive box is rotatably installed at the end of the rotating shaft away from the stirring shaft. A motor fixed to the end of the rotating shaft away from the stirring shaft is installed inside the drive box. A lifting mechanism for driving the stirring blades to rise and fall is provided on one side of the surface of the stirring shaft.

[0011] By adopting the above technical solution, the motor provides power to the rotating shaft, causing the rotating shaft to rotate. The rotating shaft drives the stirring shaft to rotate, and the stirring shaft drives the stirring blades to rotate, so that the stirring blades stir the liquid medicine inside the heat insulation sleeve.

[0012] Preferably, the lifting mechanism includes an adjustment box fixed to one side of the sealing cover surface, an electric push rod is provided on the inner wall of the adjustment box, the telescopic end of the electric push rod is slidably disposed inside the adjustment box and fixed to the side of the drive box away from the stirring shaft, and the drive box is slidably disposed inside the adjustment box.

[0013] By adopting the above technical solution, the electric actuator provides power to the drive box, enabling the drive box to move vertically. The drive box drives the rotating shaft to move vertically, the rotating shaft drives the stirring shaft to move vertically, and the stirring shaft drives the stirring blades to move vertically, so that the stirring blades can stir the liquid at different depths.

[0014] Preferably, an elastic metal sheet is fixedly mounted on the end of the stirring blade away from the stirring shaft and on the end of the scraper near the stirring blade. A guide post is symmetrically fixed on the end of the stirring blade away from the stirring shaft and slidably mounted on the end of the scraper near the stirring blade. The guide post is located on both sides of the surface of the elastic metal sheet.

[0015] By adopting the above technical solution, the stirring blade provides power to the elastic metal sheet, causing the elastic metal sheet to rotate. The elastic metal sheet drives the scraper to rotate, so that the scraper scrapes off the residual medicine on the surface of the heat insulation sleeve. At the same time, the guide column limits the scraper to prevent the scraper from deviating.

[0016] Preferably, an observation window is fixedly provided on one side of the surface of the sealing cover, and a sampling sealing plug and a dosing sealing plug are threadedly connected to one side of the surface of the observation window.

[0017] By adopting the above technical solution, the observation window allows laboratory personnel to conveniently observe the stirring and heating of the drug inside the button switch. The sampling and dosing sealing plugs are detachably installed on the surface of the observation window, facilitating the addition of drugs and sampling operations.

[0018] Preferably, the surface of the stirring blade is serrated on both sides, and the angle of the serration tip is in the range of 15°-45°.

[0019] By adopting the above technical solution, and by setting the two sides of the stirring blade surface to be serrated, a high-frequency cutting effect will be generated on the liquid medicine when the stirring blade rotates, breaking large liquid clumps or precipitates into smaller particles, thereby accelerating the diffusion and mixing of different components.

[0020] Preferably, a mounting base is fixed to one side of the surface of the mixing tank, and an industrial camera is fixed inside the mounting base.

[0021] By adopting the above technical solution, the state of the liquid medicine can be observed through an industrial camera, making it easier for users to sample and add medicine according to the state of the liquid medicine.

[0022] Preferably, the elastic metal sheet is made of medical-grade austenitic stainless steel.

[0023] By adopting the above technical solution and making the elastic metal sheet a medical-grade austenitic stainless steel material, the elastic metal sheet can fully meet the stringent requirements of the drug contact environment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The serrated stirring blades generate a high-frequency cutting effect on the liquid medicine, breaking large liquid clumps or precipitates into smaller particles, accelerating the diffusion and mixing of different components, and the scraper effectively removes the residue of high-viscosity liquid medicine adhering to the wall, avoiding uneven mixing caused by the liquid medicine adhering to the wall surface, and providing uniformity of liquid medicine stirring.

[0026] 2. The stirring shaft is driven to move vertically by an electric actuator, which can flexibly adjust the position of the stirring blades and scraper according to the depth of the liquid, ensuring that the stirring blades and scraper are always in the effective stirring area of ​​the liquid, avoiding dry rotation or collision with the bottom of the container. It can also be used with an industrial camera to observe the state of the liquid in real time, so that users can take samples and add drugs according to the state of the liquid.

[0038] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0039] This application discloses a drug supply stirring and heating device for pharmacological purposes.

[0040] Reference Figure 1 A pharmacological drug supply stirring and heating device includes a stirring tank 1. A sealing cap 2 is threadedly connected to one side of the surface of the stirring tank 1. A retaining ring is fixed to the side of the sealing cap 2 near the surface of the stirring tank 1. An external thread is provided on one side of the surface of the retaining ring. An annular groove is formed on the side of the surface of the stirring tank 1 near the sealing cap 2. The surface of the retaining ring on the surface of the sealing cap 2 abuts against the surface of the annular groove. An internal thread is provided on the inner surface of the annular groove to engage with the external thread, so that the retaining ring is fixed inside the annular groove by the engagement of the external thread and the internal thread. The outer surface of the sealing cap 2 is provided with anti-slip texture to facilitate the rotation of the sealing cap 2. A universal wheel 11 is installed at the end of the stirring tank 1 away from the sealing cap 2. A drive frame 12 is fixed to one side of the surface of the stirring tank 1. The side of the drive frame 12 away from the stirring tank 1 is L-shaped. A push-button switch 13 is fixed to the side of the drive frame 12 away from the universal wheel 11. A heat insulation sleeve 14 is fixed to the inner wall of the stirring tank 1.

[0041] By manually pushing the drive frame 12 to provide power to the mixing tank 1, the mixing tank 1 is equipped with casters 11 that can move. At the same time, by rotating the sealing cover 2, the sealing cover 2 can be detachably installed on the side of the mixing tank 1 away from the casters 11.

[0042] Reference Figures 1-5 The mixing tank 1 is equipped with a multi-layer processing mechanism 4 for stirring the medicinal liquid and scraping off residual medicinal liquid from the inner wall of the heat insulation sleeve 14. The multi-layer processing mechanism 4 includes a drive box 41 disposed on one side of the surface of the mixing tank 1. A motor 42 is fixed inside the drive box 41. The output end of the motor 42 is fixed to a rotating shaft 43 via a coupling. The rotating shaft 43 is rotatably disposed on the middle side of the drive box 41 near the surface of the mixing tank 1 via a bearing. The bearing includes an inner ring, an outer ring, rolling elements, and a cage. The bearing is an existing and mature technology, and its principle will not be described in detail. The outer ring of the bearing on the surface of the rotating shaft 43 is fixed to the middle side of the drive box 41 near the surface of the mixing tank 1. One end of the mixing tank 1 has an installation groove 431. The end of the rotating shaft 43 near the mixing tank 1 is fixed with a stirring shaft 44. The stirring shaft 44 passes through the middle of one side of the surface of the sealing cover 2, and the surface of the stirring shaft 44 abuts against the inner wall of the through-hole in the middle of one side of the surface of the sealing cover 2. The end of the stirring shaft 44 near the rotating shaft 43 has an installation groove 441, so that the first installation groove 431 and the second installation groove 441 are connected to form an installation space. The inside of the stirring shaft 44 has a heating chamber 442, and the heating wire 45 is fixed inside the heating chamber 442. The installation space is used to install a conductive slip ring that provides power to the heating wire 45, so that the stirring shaft 44 can normally provide power to the heating wire 45 when it rotates.

[0043] It should be noted that the conductive slip ring includes a conductive ring, a brush, insulating material, a housing, and a bearing. The conductive slip ring is an existing and mature technology. The principle of the conductive slip ring will not be described in detail. The distance between the inner wall of the heating chamber 442 and the outer surface of the stirring shaft 44 is 0.5-3mm.

[0044] The user connects the power supply to the conductive slip ring, heating wire 45, and push-button switch 13 respectively. The conductive slip ring is connected to the push-button switch 13 and heating wire 45 respectively. When the push-button switch 13 is pressed to the ON position, the conductive slip ring is energized and the heating wire 45 starts to work. When the push-button switch 13 is pressed to the OFF position, the conductive slip ring is de-energized and the heating wire 45 stops working. The conductive slip ring is fully sealed and has an IP67 protection rating, making it resistant to liquid corrosion.

[0045] Heating wire 45 heats the inside of heating chamber 442, and heat is transferred to the surface of stirring shaft 44 through heat conduction, so that the surface of stirring shaft 44 heats the medicine liquid. At the same time, motor 42 provides power to rotating shaft 43, so that rotating shaft 43 drives stirring shaft 44 to rotate.

[0046] Reference Figures 1-7 Multiple stirring blades 46 for stirring the liquid are fixedly mounted on the surface of the stirring shaft 44. The surfaces of the stirring blades 46 are serrated, with a tooth tip angle ranging from 15° to 45°, an edge roughness ranging from 0.8 μm to 4.0 μm, a tooth height ranging from 3 to 10 mm, and a density of 5 to 10 teeth / cm. An elastic metal sheet 47 is fixedly mounted at the end of the stirring blade 46 away from the stirring shaft 44. A scraper 48 is fixedly mounted at the end of the elastic metal sheet 47 away from the stirring blade 46. The scraper 48 has a double-beveled surface at the end away from the stirring blade 46. Guide posts 461 are symmetrically fixed at the end of the stirring blade 46 away from the stirring shaft 44. The guide posts 461 are designed... On both sides of the surface of the elastic metal sheet 47, the scraper 48 is symmetrically provided with guide grooves 481 at the end near the stirring blade 46. The end of the guide post 461 away from the stirring blade 46 abuts against the inner wall of the guide groove 481, so that the guide post 461 can slide stably inside the guide groove 481. A limiting block 462 is fixed on the surface of the end of the guide post 461 away from the stirring blade 46. A limiting groove 482 is provided on the inner wall of the guide groove 481. The surface of the limiting block 462 abuts against the surface of the limiting groove 482, so that the limiting block 462 can slide stably inside the limiting groove 482. The end of the scraper 48 away from the stirring blade 46 abuts against the inner wall of the heat insulation sleeve 14.

[0047] It should be noted that the thickness of the elastic metal sheet 47 is 0.5-1mm and the elastic modulus is 190-210GPa, to ensure that the contact pressure between the scraper 48 and the inner wall of the heat insulation sleeve 14 is 0.1-0.3N.

[0048] The stirring shaft 44 provides power to the stirring blades 46, causing the stirring blades 46 to rotate and stir the medicine liquid. At the same time, the stirring blades 46 drive the elastic metal sheet 47 to rotate, and the elastic metal sheet 47 drives the scraper 48 to rotate, so that the scraper 48 can scrape off the residual medicine liquid on the inner wall of the heat insulation sleeve 14 while the stirring blades 46 are stirring.

[0049] Reference Figures 1-3A lifting mechanism 3 for driving the stirring blades 46 to rise and fall is provided on one side of the surface of the stirring shaft 44. The lifting mechanism 3 includes an adjustment box 31 fixed to one side of the surface of the sealing cover 2. An electric push rod 32 is provided on the inner wall of the adjustment box 31. The fixed end of the electric push rod 32 is fixed to the inner wall of the adjustment box 31. A limiting plate 311 is fixed to the inner wall of the adjustment box 31. The telescopic end of the electric push rod 32 passes through the middle of the limiting plate 311 near the surface of the electric push rod 32. The telescopic end of the electric push rod 32 is fixed to the surface of the drive box 41 away from the stirring shaft 44. On one side of the center, sliders 411 are fixed on both sides of the surface of the drive box 41. Slide grooves 312 are opened on both sides of the inner wall of the adjustment box 31. The surface of sliders 411 abuts against the inner wall of the limiting plate 311, so that sliders 411 can slide stably inside the limiting plate 311. Micro switches 33 are fixed on both sides of the inner wall of the slide grooves 312. The contacts of micro switches 33 face the surface of sliders 411, so that sliders 411 can press the contacts of micro switches 33, so that micro switches 33 can control the running state of electric push rod 32.

[0050] The electric actuator 32 provides power to the drive box 41, causing the drive box 41 to move vertically. The drive box 41 drives the motor 42 and the rotating shaft 43 to move vertically. The rotating shaft 43 drives the stirring shaft 44 to move vertically. The stirring shaft 44 drives the stirring blade 46 to move vertically. The stirring blade 46 drives the elastic metal sheet 47 to move vertically. The elastic metal sheet 47 drives the scraper 48 to move vertically, thereby adjusting the position of the stirring blade 46 and the scraper 48 according to the depth of the liquid.

[0051] Reference Figures 1-5 A positioning shaft 17 is fixedly installed in the middle of the inner wall of the mixing tank 1. The positioning shaft 17 passes through the end of the mixing shaft 44 away from the rotating shaft 43 and is slidably mounted on the side wall of the heating chamber 442. The diameter of the positioning shaft 17 is smaller than the inner diameter of the heating wire 45, so that the positioning shaft 17 passes through the middle of the heating wire 45. The surface of the end of the positioning shaft 17 away from the inner wall of the mixing tank 1 abuts against the end of the mixing shaft 44 away from the rotating shaft 43, so that the positioning shaft 17 can stably pass through the end of the mixing shaft 44 away from the rotating shaft 43. Multiple sealing rings 443 are fixedly installed at the end of the mixing shaft 44 away from the rotating shaft 43. The inner surface of the sealing rings 443 abuts against the surface of the positioning shaft 17, so that the mixing shaft 44 can always seal the heating chamber 442 and the end of the mixing shaft 44 away from the rotating shaft 43 through the sealing rings 443 during the movement of the mixing shaft 44, ensuring that the medicine inside the mixing tank 1 will not enter the interior of the heating chamber 442.

[0052] It should be noted that: the electric actuator 32 drives the drive box 41 to move vertically. When the end of the drive box 41 close to the sealing cover 2 contacts the side of the sealing cover 2 away from the mixing tank 1, the surface of the slider 411 presses the contact of the micro switch 33 located below the slider 411. At this time, the end of the stirring shaft 44 away from the rotating shaft 43 contacts the bottom wall of the mixing tank 1.

[0053] The stirring shaft 44 is limited by the positioning shaft 17 to prevent the positioning shaft 17 from shifting.

[0054] Reference Figures 1-4 An observation window 21 is fixedly provided on one side of the surface of the sealing cover 2. A sampling port and a drug dosing port are provided on one side of the surface of the observation window 21. A sampling sealing plug 22 and a drug dosing sealing plug 23 are provided on one side of the surface of the observation window 21. The outer surface of the sampling sealing plug 22 is provided with an external thread, and the inner wall of the sampling port is provided with an internal thread that engages with the external thread on the surface of the sampling sealing plug 22, so that the sampling sealing plug 22 can be fixed inside the sampling port by the engagement of the external thread and the internal thread, thereby sealing the sampling port. The outer surface of the drug dosing sealing plug 23 is provided with an external thread, and the inner wall of the drug dosing port is provided with an internal thread that engages with the external thread on the surface of the drug dosing sealing plug 23, so that the drug dosing sealing plug 23 can be fixed inside the drug dosing port by the engagement of the external thread and the internal thread, thereby sealing the drug dosing port.

[0055] The observation window 21 allows the experimenter to observe the stirring and heating of the drug inside the push-button switch 13. The sampling sealing plug 22 and the drug addition sealing plug 23 are detachably mounted on the surface of the observation window 21, facilitating the addition of drugs and sampling operations.

[0056] Reference Figures 1-5 A mounting base 15 is fixed on one side of the surface of the mixing tank 1. The side of the mounting base 15 near the heat insulation sleeve 14 is on the same vertical line as the inner surface of the heat insulation sleeve 14. An industrial camera 16 is fixed inside the mounting base 15, and the camera surface of the industrial camera 16 faces the inside of the mixing tank 1.

[0057] It should be added that the user needs to install a display on the side of the mixing tank 1 near the mounting base 15 and connect the industrial camera 16 to the display.

[0058] The state of the liquid inside the mixing tank 1 is displayed on the screen using an industrial camera 16, making it easy for users to analyze the state of the liquid.

[0059] It should be noted that the user needs to install the controller on the surface of the limit plate 311, connect the controller, electric push rod 32, push button switch 13, two micro switches 33, and drive box 41 to the power supply respectively, connect the electric push rod 32 to the controller, and connect the controller to push button switch 13 and two micro switches 33.

[0060] When the push-button switch 13 connected to the electric actuator 32 is pressed to the ON position, the electric actuator 32 starts to work; when the push-button switch 13 is pressed to the OFF position, the electric actuator 32 stops working.

[0061] When the end of the drive box 41 near the sealing cover 2 comes into contact with the side of the sealing cover 2 away from the mixing tank 1, the surface of the slider 411 presses the contact of the micro switch 33 located below the slider 411, causing the electric push rod 32 to change from the extended mode to the retracted mode, and causing the telescopic end of the electric push rod 32 to retract; when the upper surface of the slider 411 moves close to the micro switch 33 on the upper surface of the slider 411, the upper surface of the slider 411 presses the contact of the micro switch 33 located above the slider 411, causing the electric push rod 32 to stop running.

[0062] The user needs to install a relay on the surface of the limit plate 311, connect the relay, push button switch 13, and motor 42 to the power supply respectively, connect the push button switch 13 to the relay, and connect the relay to the motor 42. When the push button switch 13 is pressed to the ON position, the relay is energized and the motor 42 starts to work. When the push button switch 13 is pressed to the OFF position, the relay is de-energized and the motor 42 stops running.

[0063] It should be added that: this device is used for experimental teaching in pharmacology and pharmaceutics courses. The internal volume of the stirring tank 1 ranges from 0.5 to 1.5 L, the total weight of the device is 5 to 9 kg, and the distance between the stirring blades 46 and the inner wall of the heat insulation sleeve 14 is 1 to 3 cm.

[0064] Motor 42 uses Leadshine MD-5422 series, electric actuator 32 uses Airtac ANJ-50-100-S series, industrial camera 16 uses Hikvision MV-CE200-11GM series, conductive slip ring uses Moflon LPC004 series, push button switch 13 uses Letuo Technology R13-507 series, caster wheel 11 uses Huilide gravity self-locking wheel circlip series, micro switch 33 uses Yatelian Technology Co., Ltd. MQS57 series, heating wire 45 uses Cr20Ni80 series, and display uses Haifei Zhixian HF-67040-X012-AO series.

[0065] The heat insulation sleeve 14 is a double-layer vacuum insulation structure, with the inner layer being 316L stainless steel and the outer layer being polypropylene. The main body of the mixing tank 1 is Q235 carbon steel, with an epoxy resin anti-corrosion coating on the surface. The side of the mounting base 15 near the stirring shaft 44 is made of engineering plastic ABS material. The heating wire 45 is made of nickel-chromium alloy. The stirring shaft 44 is made of 42CrMo steel. The stirring blade 46 is made of 316L stainless steel. The observation window 21 is made of borosilicate glass. The sampling sealing plug 22 and the drug dosing sealing plug 23 are made of medical-grade silicone. The elastic metal sheet 47 is made of medical-grade austenitic stainless steel. The scraper 48 is made of ultra-high molecular weight polyethylene. The guide groove 481 and the limiting groove 482 are made of the same material as the scraper 48.

[0066] The implementation principle of the pharmacological drug supply stirring and heating device in this application embodiment is as follows: When using this device, the user manually pushes the drive frame 12 to move the stirring tank 1 to the drug supply point via the universal wheels 11. After reaching the drug supply point, the device is fixed by the self-locking performance of the universal wheels 11. Then, the user manually rotates the sealing cover 2 counterclockwise. The sealing cover 2 drives the insert ring to rotate counterclockwise, so that the insert ring is disengaged from the annular groove on the side of the stirring tank 1 away from the universal wheels 11 by means of the thread. This causes the sealing cover 2 to move the lifting mechanism 3 and the multi-layer processing mechanism 4 out of the interior of the stirring tank 1. The drug solution is then poured into the interior of the stirring tank 1. After the drug solution is completely poured in, the insert ring on one side of the surface of the sealing cover 2 is re-fixed into the annular groove on one side of the surface of the stirring tank 1. The operation process is the same as above, but in the opposite direction. After the drug solution is added, the installation of the lifting mechanism 3 and the multi-layer processing mechanism 4 is completed.

[0067] The user starts the motor 42 by pressing the button switch 13 connected to the motor 42 to the ON position. The output end of the motor 42 drives the rotating shaft 43 to rotate, the rotating shaft 43 drives the stirring shaft 44 to rotate, and the stirring shaft 44 drives the stirring blades 46 to rotate. The stirring blades 46 stir the medicine liquid inside the stirring tank 1, so that the components in the medicine liquid are evenly mixed. At the same time, the user presses the button switch 13 connected to the heating wire 45 to the ON position, so that the heating wire 45 starts to work. The heat generated by the heating wire 45 is conducted to the medicine liquid through the stirring shaft 44, so that the medicine liquid is heated at the same time during the stirring process, thereby accelerating the reaction efficiency of the components in the medicine liquid.

[0068] When the stirring blade 46 rotates, it drives the guide column 461 and the elastic metal sheet 47 to rotate, which in turn drives the scraper 48 to rotate. The scraper 48 scrapes off the liquid medicine adsorbed on the inner wall of the heat insulation sleeve 14, preventing the liquid medicine from forming a wall-hanging phenomenon on the inner wall of the heat insulation sleeve 14.

[0069] When the user needs to add other drugs, the user can manually turn the drug addition sealing plug 23 counterclockwise to disengage the drug addition sealing plug 23 from the inside of the drug addition port by means of the thread, thereby releasing the sealing state of the drug addition sealing plug 23 on the drug addition port. The user can then add other drugs into the inside of the mixing tank 1 through the drug addition port to mix with the drug solution inside the mixing tank 1, which facilitates the user's drug addition operation. After adding the drugs, the user can manually turn the drug addition sealing plug 23 clockwise to reseal the drug addition port.

[0070] The state of the liquid inside the mixing tank 1 is displayed on the screen using an industrial camera 16, which allows the user to analyze the state of the liquid and choose to add drugs or take out a portion as a sample based on the mixing state of the liquid.

[0071] When the user needs to remove a portion of the medicine inside the mixing tank 1 as a sample, the user manually rotates the sampling sealing plug 22 counterclockwise to disengage the sampling plug 22 from the inside of the sampling port via the thread, thus releasing the sealing state of the sampling port. The user then uses a sampling tool, such as a spoon, to remove a portion of the liquid medicine inside the mixing tank 1 through the sampling port as a sample. This method facilitates the user's sampling operation. After sampling, the user manually rotates the sampling sealing plug 22 clockwise to reseal the sampling port.

[0072] When the push-button switch 13 connected to the electric actuator 32 is pressed to the ON position, the push-button switch 13 controls the electric actuator 32 to start working. The telescopic end of the electric actuator 32 begins to extend. The telescopic end of the electric actuator 32 drives the drive box 41 to move downward. The drive box 41 drives the rotating shaft 43 to move downward. The rotating shaft 43 drives the stirring shaft 44 to move downward. The stirring shaft 44 drives the stirring blade 46 to move downward. The stirring blade 46 drives the elastic metal sheet 47 and the guide column 461 to move downward. The guide column 461 and the elastic metal sheet 47 drive the scraper 48 to move downward, so that the stirring blade 46 and the scraper 48 are always kept inside the liquid, so that the stirring blade 46 can better stir the liquid.

[0073] The stirring blade 46 is connected to the scraper 48 by an elastic metal sheet 47. The deformation of the elastic metal sheet 47 can absorb the collision energy, so that the scraper 48 can automatically avoid solid particles, reducing the risk of mechanical damage. It is suitable for stirring fragile liquids such as liposomes and nano-formulations.

[0074] When the drive box 41 moves to the side of the sealing cover 2 away from the mixing tank 1, the surface of the slider 411 presses the contact of the micro switch 33 located below the slider 411, causing the electric push rod 32 to change from the extended mode to the retracted mode, and causing the telescopic end of the electric push rod 32 to retract. The telescopic end of the electric push rod 32 drives the multi-layer processing mechanism 4 to move upward. When the upper surface of the slider 411 moves to the micro switch 33 near the upper surface of the slider 411, the upper surface of the slider 411 presses the contact of the micro switch 33 located above the slider 411, causing the electric push rod 32 to stop running.

[0075] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
