Abstract
Description
Technical Field
[0001] This utility model mainly relates to the technical field of dissolution meters, specifically an automatic cleaning device for dissolution cups. Background Technology
[0002] A dissolution meter is an instrument used to determine the rate and extent to which a drug dissolves from a solid dosage form (such as tablets, capsules, granules, etc.) under specified conditions. It is a commonly used device in drug research and development, production and quality control. By simulating the digestive environment of a drug in the body, it helps to evaluate the bioavailability of the drug and the quality of the formulation. The core structure mainly includes a stirring device, a lifting mechanism, a dissolution cup, a constant temperature circulation device, and a control system and software.
[0003] The dissolution meter operation steps are as follows: First, adjust the instrument, fix the dissolution cup and pour in the dissolution medium preheated to 37°C, calibrate the position of the stirring paddle / rotating basket, then start the constant temperature system to stabilize the medium temperature, set the stirring speed, then take the sample and put it into the rotating basket or directly into the dissolution cup, start stirring and start timing, take samples at the specified time points (while replenishing the medium at the same temperature), measure the concentration after the sample is filtered, and finally calculate the dissolution rate.
[0004] After the dissolution test, each dissolution vessel needs to be processed according to the subsequent experimental procedures. Currently, each dissolution vessel needs to be manually removed, the residual solution poured out, and then rinsed with clean water. Since each dissolution vessel has a capacity of 1000 ml, and the dissolution test requires the operation of 6 or more dissolution vessels, the total weight of the vessel and residual solution after the experiment is quite large. Manual handling, pouring, and rinsing require continuous force, making the operation tedious and repetitive. This is especially physically demanding for women, as it is very time-consuming and laborious. At the same time, the residual liquid on the vessel wall can easily cause the dissolution vessel to slip, which may not only cause it to fall and break, resulting in damage to the instrument, but also pose safety risks such as cuts to the operator and contact with irritating liquids due to broken glass and residual solution. This step has become a prominent problem affecting the overall efficiency and operational safety of the experiment. Utility Model Content
[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides an automatic cleaning device for dissolution cups, which solves the technical problem mentioned in the background that after the dissolution experiment, each dissolution cup needs to be manually removed, the residual solution inside the cup poured out, and then cleaned with water. However, the total weight of the cup and the residual solution after the experiment is large, which can easily lead to slippage and breakage of the dissolution cup.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0007] An automatic cleaning device for dissolution cups includes a base, on which a movable platform with lifting function is mounted. Multiple rotatable stirring shafts are mounted on the movable platform, and the stirring shafts and the movable platform are connected by a plug-in connection. A self-cleaning mechanism is mounted on the base, comprising a wastewater tank and a water bath. The water bath is located on the wastewater tank and is covered by a cover plate. Multiple dissolution cup bodies are evenly spaced on the cover plate, and each dissolution cup body has a top cover. A stirring shaft passes through the top cover to stir the liquid inside the dissolution cup body. A cleaning component and a suction pipe are respectively installed on the lower side and in a through-hole of the top cover, and the suction pipe and the top cover are movably connected.
[0008] Furthermore, the cleaning component includes an annular groove, the outer wall of which is surrounded by a plurality of nozzles, and the nozzles face the inner wall of the dissolution cup body.
[0009] Furthermore, a magnetic sheet is provided in the annular groove on the lower side of the top cover, and a metal sheet is attached to the magnetic sheet. The metal sheet is located at the lower end of the suction tube.
[0010] Furthermore, a first pump body is provided at the outlet position on one side of the outer wall of the water bath, and a first guide pipe is provided at the output end of the first pump body. Multiple first hoses are linearly arranged at equal intervals on the first guide pipe, and the first hoses are connected to the through holes on the corresponding top cover.
[0011] Furthermore, the protrusion on the lower side of the top cover and the groove on the upper side of the cover plate are engaged and connected.
[0012] Furthermore, a second pump body is provided at the inlet position on one side of the outer wall of the wastewater tank, and a second guide pipe is provided at the input end of the second pump body. Multiple second hoses are linearly arranged at equal intervals on the second guide pipe, and the second hoses are connected to the upper end of the corresponding suction pipe.
[0013] Furthermore, annular clamps are provided between the second guide pipe and the wastewater tank, and between the first guide pipe and the water bath, for positioning the guide pipes.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through its base, moving platform, wastewater tank, water bath, cover plate, guide pipe, hose, top cover, cleaning components, suction pipe, and pump body, enables automatic cleaning of dissolution cups after dissolution experiments. This replaces the repetitive manual process of emptying and cleaning each cup individually, avoiding the laborious handling issues caused by the large capacity and liquid content of the dissolution cups. It significantly reduces the physical exertion required for female operators, greatly shortens cleaning time, and eliminates the risk of breakage due to slipping from the water bath. This reduces safety hazards caused by glass breakage and solution contact. The standardized liquid suction, water injection, and rinsing process avoids uneven cleaning and incomplete removal of residual liquid during manual cleaning, improving the consistency of dissolution cup cleanliness and ensuring the accuracy of subsequent experiments.
[0016] Furthermore, the combination of the magnetic sheet and the metal sheet allows the suction tube to be attached to the top cover before the stirring shaft starts stirring, preventing interference with the stirring shaft blades. This ensures stable operation and ease of use, making it a practical device.

[0027] Please refer to the appendix carefully. Figures 1-5 An automatic cleaning device for dissolution cups includes a base 1, on which a movable platform 2 with lifting function is provided. Multiple rotatable stirring shafts 4 are provided on the movable platform 2, and the stirring shafts 4 and the movable platform 2 are connected by a plug-in connection. A self-cleaning mechanism 3 is provided on the base 1. The self-cleaning mechanism 3 includes a wastewater tank 31 and a water bath 32, with the water bath 32 located on the wastewater tank 31. A cover plate 33 is provided on the water bath 32, and multiple dissolution cup bodies 5 are evenly spaced on the cover plate 33. Each dissolution cup body 5 is provided with a top cover 36. The stirring shafts 4 penetrate the top cover 36 to stir the liquid inside the dissolution cup body 5. A cleaning component 37 and a suction pipe 39 are respectively provided on the lower side and in the through hole of the top cover 36, and the suction pipe 39 and the top cover 36 are movably connected.
[0028] The above structure enables automatic cleaning of dissolution cups after dissolution experiments, replacing the repetitive manual process of pouring and cleaning each cup individually. This avoids the difficulty of handling large-capacity dissolution cups containing liquid, especially reducing the physical exertion required for female operators, significantly shortening cleaning time, and eliminating the risk of slipping and breaking the cups due to slipping. This reduces safety hazards caused by glass breakage and solution contact. The standardized liquid aspiration, water injection, and rinsing process avoids uneven cleaning and incomplete removal of residual liquid during manual cleaning, improving the consistency of dissolution cup cleanliness and ensuring the accuracy of subsequent experiments. Furthermore, the structure is stable, easy to operate, and has practical value.
[0029] The specific operation is as follows: After the experiment, turn off the stirring shaft 4, then push the suction tube 39 downwards to separate the metal plate 391 and the magnet plate 361 on the suction tube 39. The lower end of the suction tube 39 contacts the bottom of the dissolution cup body 5. Then, start the second pump body 7 to draw the liquid in the dissolution cup from the suction tube 39, and then through the second hose 351 and the second guide tube 38 into the wastewater tank 31 for temporary storage. Then, turn on the first pump body 6 to draw out the clean water in the water bath 32. The wastewater enters the annular tank 371 through the first guide tube 34 and the first hose 35, and then is sprayed onto the inner wall of the dissolution cup through the nozzle 372. Alternatively, the suction pipe 39 can be lifted and the stirring shaft 4 can be turned on for auxiliary cleaning. After cleaning, the stirring shaft 4 is turned off, and the suction pipe 39 is pushed to the bottom of the cup again to pump the wastewater into the wastewater tank 31. Repeat the above steps to clean the dissolution cup body 5. The wastewater tank 31 can be periodically connected to an external pipe to collect and guide the wastewater into an indoor water tank.
[0030] Please refer to the appendix carefully. Figure 2 and attached Figure 3A first pump body 6 is installed at the outlet position on one side of the outer wall of the water bath 32.

Through the cooperation between the second guide tube 38, the second hoses 351 and the second pump body 7, the wastewater in the dissolution cup body 5 is pumped into the wastewater tank 31. Annular clamps 341 are provided between the second guide tube 38 and the wastewater tank 31, and between the first guide tube 34 and the water bath 32, for positioning the guide tubes.
[0031] Please refer to the appendix carefully. Figure 4 and attached Figure 5 The cleaning component 37 includes an annular groove 371. Multiple nozzles 372 are arranged around the outer wall of the annular groove 371, and the nozzles 372 face the inner wall of the dissolving cup body 5, which facilitates rinsing of the cup wall and improves the cleaning intensity. A magnetic piece 361 is arranged in the annular groove on the lower side of the top cover 36. The magnetic piece 361 is connected to a metal piece 391. The metal piece 391 is located at the lower end of the suction tube 39. Through the cooperation between the magnetic piece 361 and the metal piece 391, the bottom of the suction tube 39 can be attracted to the lower side of the top cover 36 during the rotation of the stirring shaft 4, avoiding interference.
