Description

Technical Field

[0001] This invention relates to the field of medicine box equipment technology, specifically to a mechanism for precisely controlling the amount of medicine dispensed, an intelligent medicine box, and a control method. Background Technology

[0002] As a major global consumer of pharmaceuticals, China's elderly population forms a significant cornerstone of its drug demand. With the accelerating development of an aging society, the complexity and diversity of medication use among the elderly are becoming increasingly prominent. They not only take medication frequently but also often need to take multiple medications simultaneously. This situation directly relates to medication safety issues; incorrect medication use can significantly reduce treatment effectiveness and even endanger the patient's life. According to survey data, even with monthly follow-ups with general practitioners and revised prescriptions, as many as 20% of elderly people still exhibit non-adherence to their medication regimens.

[0003] Given the serious challenges of medication management for the elderly, a variety of smart home medicine cabinet products have emerged on the market, aiming to improve medication safety and adherence through technological means. Currently, home smart medicine boxes on the market can be roughly divided into the following three categories: (1) Small compartment medicine boxes. These medicine boxes are compact and portable, with compartments inside to distinguish different types of pills. However, their storage capacity is limited, making it difficult to meet the precise management of multiple medicines. (2) Medium compartment medicine boxes. These products effectively plan medication by dispensing pills by day or time period (morning, noon, and evening). However, there is still a high risk of accidentally opening the medicine box. Their large size makes them inconvenient to carry and cannot meet the needs of patients who take medication frequently. (3) Automatic sorting medium compartment medicine boxes, also known as home medicine robots, can automatically sort and remind users. Users only need to preset the drug information, and the medicine box can automatically pop out the required pills at the specified time, greatly reducing the risk of accidental or incorrect administration. However, they still cannot accurately deliver the number of pills. Often, due to insufficient suction force of the suction cup on the pills, the number of pills output is lower than the set number of pills. Moreover, the high price and large size limit their popularity.

[0004] While the compartmentalized design of medicine dispensers effectively reduces the possibility of accidental medication administration, users may still encounter the risk of taking the wrong medication for various reasons in practice. Furthermore, medicine dispensers with automatic dispensing functions, despite their technological innovation, are hampered by their large size and high price, hindering widespread adoption and limiting their potential for large-scale market expansion.

[0005] Therefore, existing technologies need further development. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a mechanism, intelligent medicine box and control method for precisely controlling the quantity of drugs output, so as to solve the technical problem that the quantity of drugs cannot be precisely controlled and accurately output in related technologies.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solution: A mechanism for precisely controlling the quantity of drugs output is provided, comprising: a medicine box for containing drugs; an adjustment assembly including a first driving member, a turntable, and several blades arranged sequentially around the turntable, the other ends of the blades forming an opening; the turntable communicating with the medicine box to allow drugs to enter the opening; the first driving member driving the turntable to rotate, causing the blades to rotate synchronously, thereby adjusting the size of the opening; a channel located below the opening, the diameter of which is adjustable, the channel preventing deviation when the drugs fall; and a control assembly including a second driving member and a lifting rod, the control assembly controlling the output of individual drugs; the second driving member driving the lifting rod to move within the channel; the lifting rod rising according to the drug diameter, blocking the individual drug falling from the opening, thus clamping the drug within the channel; then closing the opening and driving the lifting rod downwards to release the individual drug as it slides down.

[0008] Furthermore, the mechanism also includes a fixed frame, a first driving component being a first motor fixed to the fixed frame, and a turntable fixed to a first fixed plate of the fixed frame. The turntable includes a first turntable and a second turntable. The first turntable has protruding teeth that mesh with gears on the first motor, driving the first turntable to rotate. The first turntable has multiple first sliding grooves, and the second turntable has multiple second sliding grooves. One end of each blade is located between the first and second turntables. The adjusting assembly also includes: multiple connecting pins, each blade having a connecting hole, which connects the blade to the first turntable by passing the connecting pins through the first sliding grooves and connecting holes; when the first turntable rotates, the connecting pins move within the first sliding grooves, causing the blades to rotate synchronously to adjust the size of the opening; and multiple locking blocks, each locking block being located on the side of the blade away from the first turntable and inserted into the second sliding groove, which restricts the rotation range of the blades.

[0009] Furthermore, the blade includes a connecting plate and an adjusting plate, with an included angle between the connecting plate and the adjusting plate. Each connecting hole and each locking block are provided on the respective connecting plate. The connecting plate abuts between the first turntable and the second turntable. The adjusting plate extends in the direction of the channel, so that multiple blades are arranged around the turntable to form a conical structure. The opening is located at the end of the conical structure, thereby precisely adjusting the size of the opening.

[0010] Furthermore, the diameter of the channel is adjusted by a channel adjustment assembly, which is fixed on the second fixed plate of the fixed frame. The channel adjustment assembly includes: a base plate, on which limit pins and fixing pins are provided, with multiple limit pins and fixing pins; a rotating ring, located above the base plate, on which multiple limit grooves are provided, and each limit pin can move within its respective limit groove; multiple connecting rods, each connecting rod being hinged to the rotating ring; multiple rotating sliders, all located within the rotating ring, perpendicular to the base plate and the rotating ring, and arranged at intervals to form a channel; each rotating slider is provided with a fixing hole, through which a fixing pin passes to hinge the rotating slider to the base plate, and the end of the connecting rod away from the rotating ring is hinged to the rotating slider; and a third driving member, which drives the rotating ring to rotate, causing the rotating ring to drive the connecting rods to move synchronously, so that the multiple rotating sliders rotate around the channel and move inward or outward, thereby changing the diameter of the channel formed by the multiple rotating sliders.

[0011] Furthermore, the adjustment assembly also includes a base, which is fixed to a second fixed plate of the fixing frame, the base plate is fixed to the base, and a third drive member is fixed to the outside of the base.

[0012] Furthermore, the second driving component is a second motor, which is fixed on the third fixed plate of the fixed frame. The output end of the second motor is threadedly connected to the lifting rod, and the lifting rod is driven to move up and down by rotation.

[0013] Furthermore, the first, second, and third fixing plates are arranged vertically, and the third fixing plate has a hollow structure to facilitate the drug falling from the third fixing plate. The fixing frame also includes a side guard plate and a fixing column, both of which are connected to the first, second, and third fixing plates. The first motor is fixed to the side guard plate.

[0014] A smart medicine box includes a box body, inside which is a mechanism for precisely controlling the amount of medicine dispensed as described above. A recognition component is located at the top of the box body, comprising a recognition platform and a collector. The collector collects information about the medicine on the recognition platform. A slide is located below the recognition platform, allowing the medicine to slide into the medicine box by rotating the recognition platform. Multiple mechanisms are included, with a first support inside the box body. Multiple mechanisms are spaced apart on the first support, which is rotatably mounted relative to the box body. Rotating the first support connects a specific medicine box to the slide.

[0015] Furthermore, the smart medicine box also includes a fourth motor, and a second support is installed inside the box. The first support is located above the second support, and the fourth motor is fixed on the second support. The output end of the fourth motor is connected to the first support to drive the first support to rotate relative to the box, so that a certain medicine box is connected to the slide. The second support has a hollow structure to facilitate the medicine falling from the second support.

[0016] A control method, applied to the smart medicine box as described above, includes the following steps: Step 1: Obtain the diameter n of the medicine through an identification component; Step 2: Rotate the first support to align a medicine box with a slide rail; Step 3: Open the identification platform to allow the medicine to slide into the aligned medicine box via the slide rail; Step 4: Adjust the diameter of the channel to match the diameter n of the medicine; Step 5: A second drive unit drives a lifting rod to rise within the channel until the distance between the end of the lifting rod and the opening is N, where 0.5n < N < 1.5n; Step 6: Control the first drive unit to drive the turntable to rotate, causing the blades to rotate and adjusting the size of the opening formed by the blades to accommodate the diameter n of the medicine; Step 7: A single medicine falls from the opening, is held by the lifting rod, and is clamped within the channel, closing the opening and controlling the lifting rod to descend, releasing the single medicine; Step 8: After recognizing the single medicine falling, the lifting rod rises again, opening the opening so that the lifting rod holds the next medicine, the opening closes again, the lifting rod descends, and the operation is repeated until the number of medicines output reaches a predetermined value.

[0017] Beneficial effects:

[0018] 1. The mechanism for precisely controlling the quantity of drugs output in this invention achieves single-drug output by adjusting the size of the opening formed by the blades and precisely controlling the lifting rod, thus avoiding the problem of multiple drugs falling accidentally and effectively improving the precise control of the quantity of drugs output.

[0019] 2. Compared with existing smart medicine boxes, the smart medicine box of the present invention does not require adsorption technology, which avoids the problem of inaccurate drug output due to insufficient suction force of the suction cup, reduces complex mechanical structure and optimizes cost; at the same time, the entire drug output process is automated, which reduces the complexity of operation for users and improves user experience.

[0020] 3. The intelligent medicine box of the present invention effectively reduces the risk of medication errors caused by user mistakes or inaccurate drug dispensing by automating and precisely controlling the amount of medicine dispensed, and is especially suitable for the elderly and other groups who need to strictly follow the dosage.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] According to an embodiment of the present invention, a mechanism for precisely controlling the amount of drug dispensed is provided; please refer to [link to relevant documentation]. Figures 1 to 9 The system includes: a medicine box 2 for holding medicine; an adjustment assembly 3, including a first drive 31, a turntable 32, and several blades 33 arranged sequentially around the turntable 32, with the other ends of the blades 33 forming an opening 34; the turntable 32 communicates with the medicine box 2 to allow medicine to enter the opening 34; the first drive 31 drives the turntable 32 to rotate, causing the blades 33 to rotate synchronously, thereby adjusting the size of the opening 34; a channel 4 located below the opening 34, the diameter of which is adjustable to prevent the medicine from deviating when falling; and a control assembly 5, including a second drive 51 and a lifting rod 52, which controls the output of individual medicines; the second drive 51 drives the lifting rod 52 to move within the channel 4; the lifting rod 52 rises according to the diameter of the medicine, blocking the individual medicine falling from the opening 34, thus clamping the medicine within the channel 4; then the opening 34 is closed, and the lifting rod 52 is driven to descend, releasing the individual medicine from sliding down.

[0034] The mechanism for precisely controlling the quantity of drugs output in this embodiment, taking spherical granules as an example, involves a drug box 2 connected to a turntable 32. A first drive unit 31 drives the turntable 32 to rotate, causing the opening 34 formed by the blades 33 to adjust its size to accommodate the drug's diameter. This step ensures the opening size is just large enough to allow a single granule to pass through, preventing multiple granules from falling simultaneously. A channel 4 is located directly below the opening 34, and its diameter can be adjusted according to the drug's diameter to ensure the drug does not deviate or tilt during its descent. The channel 4 constrains the drug's trajectory to maintain its stability. A lifting rod 52 rises to a set height based on the drug's diameter, stopping the falling granule. At this point, the drug is held within the channel 4 by the lifting rod 52, ensuring only one granule remains in this position. Once the drug is held by the lifting rod 52, the blades 33 rotate synchronously, closing the opening 34 and preventing other drugs from entering the channel 4. After the opening 34 closes, the second drive unit 51 controls the lifting rod 52 to descend, causing the clamped single drug to slide out of the channel 4, thus completing the precise output of a single drug. By automatically adjusting the size of the opening 34 and controlling the movement of the lifting rod 52 through the first and second drive units 31, and then clamping the single drug falling from the opening 34 within the channel 4 with an adjustable diameter, the system precisely controls the output of only one drug at a time, avoiding the simultaneous falling of multiple drugs. This embodiment is applicable to drugs of different diameters. By adjusting the size of the opening 34 and the channel 4, it can flexibly handle various types and sizes of drugs, offering a wide range of applications. The mechanism for precisely controlling the number of drugs output in this embodiment solves the technical problem in related technologies where the number of drugs cannot be precisely controlled and accurately output.

[0035] See Figure 1 , Figure 2 and Figure 3 The mechanism for precisely controlling the amount of drug output in this embodiment also includes a fixed frame 6. The first driving component 31 is a first motor 311, which is fixed on the fixed frame 6. The turntable 32 is fixed on the first fixed plate 61 of the fixed frame 6. The turntable 32 includes a first turntable 321 and a second turntable 322. The first turntable 321 is provided with a tooth 3211, which meshes with the gear 3111 on the first motor 311, driving the first turntable 321 to rotate. The first turntable 321 is provided with multiple first sliding grooves 3212, and the second turntable 322 is provided with multiple second sliding grooves 3221. One end of each blade 33 is located between the first turntable 321 and the second turntable 322. The adjusting assembly 3 also includes: multiple connecting pins 35, each blade 33 is provided with a connecting hole 333, and the connecting pins 35 pass through the first sliding grooves 3212 and the connecting holes 333 to connect the blade 33 and the first turntable 321; when the first turntable 321 rotates, the connecting pins 35 move in the first sliding grooves 3212, driving the blades 33 to rotate synchronously to adjust the size of the opening 34; multiple locking blocks 36, each locking block 36 is respectively located on the side of the blade 33 away from the first turntable 321 and inserted into the second sliding grooves 3221, limiting the rotation range of the blade 33 through the second sliding grooves 3221 and the locking blocks 36. Through the meshing transmission between the convex teeth 3211 and the gears 3111, the first motor 311 can drive the first turntable 321 to rotate. In the adjusting assembly 3, the first turntable 321 and the second turntable 322 drive the blades 33 to form an opening 34. The first turntable 321 can be driven to rotate by the first driving component 31, thereby precisely adjusting the size of the opening 34. This structure ensures that the opening size can accurately adapt to drugs of different diameters, achieving precise output of a single drug and preventing the simultaneous falling of multiple drugs. Each blade 33 is connected to the first slide groove 3212 via a connecting pin 35 and engages with the second slide groove 3221 via a locking block 36, limiting the rotation range of the blade 33. This design ensures the consistency and stability of blade rotation, making the adjustment of the opening 34 smoother and more reliable, avoiding the reduction in output accuracy caused by blade wobbling or positional deviation.

[0036] See Figure 3In this embodiment, the mechanism for precisely controlling the amount of drug output includes blades 33, each comprising a connecting piece 331 and an adjusting piece 332. An angle is formed between the connecting piece 331 and the adjusting piece 332. Each connecting hole 333 and each locking block 36 are disposed on the connecting piece 331. The connecting piece 331 abuts between the first turntable 321 and the second turntable 322. The adjusting piece 332 extends towards the channel 4, causing multiple blades 33 to be arranged around the turntable 32 to form a conical structure. An opening 34 is located at the end of the conical structure, thereby precisely adjusting the size of the opening 34. By setting an angle between the connecting piece 331 and the adjusting piece 332, the blades 33 are arranged around the turntable 32 to form a conical structure. The opening 34, located at the end of the conical structure, effectively guides the drug to fall accurately from the opening 34, ensuring precise control over the amount of drug output each time and preventing multiple drugs from falling simultaneously.

[0037] See Figure 1 and Figure 4 In this embodiment, the mechanism for precisely controlling the amount of drug output is provided. The diameter of channel 4 is adjusted by channel adjustment assembly 7, which is fixed on the second fixed plate 62 of the fixed frame 6. Channel adjustment assembly 7 includes: a base plate 71, on which limit pins 711 and fixing pins 712 are provided, and there are multiple limit pins 711 and fixing pins 712; a rotating ring 72, located above the base plate 71, on which multiple limit grooves 721 are provided, and each limit pin 711 is movable within its respective limit groove 721; multiple connecting rods 73, each connecting rod 73 being hinged to the rotating ring 72; and multiple rotating sliders 74. Multiple rotating sliders 74 are located within the rotating ring 72, perpendicular to the base plate 71 and the rotating ring 72. These sliders are arranged at intervals to form a channel 4. Each rotating slider 74 has a fixing hole 741, through which a fixing pin 712 passes, hinges the rotating slider 74 to the base plate 71. The end of the connecting rod 73 furthest from the rotating ring 72 is hinged to the rotating slider 74. A third driving member 75 drives the rotating ring 72 to rotate, causing the rotating ring 72 to move synchronously with the connecting rod 73. This causes the multiple rotating sliders 74 to rotate around the channel 4 and move inwards or outwards, thereby changing the diameter of the channel 4 formed by the multiple rotating sliders 74. The rotating sliders 74 are hinged to the base plate 71 via the fixing pin 712, while the connecting rod 73 and the limiting pin 711 slide within the limiting groove 721, forming a stable rotating structure. The cooperation between the limiting pin 711 and the limiting groove 721 ensures the accuracy of the moving range and position of the rotating sliders 74. The precise positioning of the rotating slider 74 further ensures the accuracy of the diameter adjustment of channel 4, effectively reducing errors in the drug delivery process and improving the precision and reliability of drug delivery. The synchronous rotation and inward or outward movement of multiple rotating sliders 74 can precisely adjust the diameter of channel 4. The rotating slider 74 has a long strip structure (e.g., Figure 5As shown, the more sliders 74 are rotated, the closer channel 4 becomes to a circle, making the size of channel 4 more compatible with the diameter of the drug.

[0038] See Figure 1 and Figure 6 In this embodiment, the mechanism for precisely controlling the amount of drug output includes a channel assembly 7, which further comprises a base 76. The base 76 is fixed to the second fixed plate 62 of the fixing frame 6, the base plate 71 is fixed to the base 76, and the third drive member 75 is fixed to the outside of the base 76. The base 76 firmly fixes the base plate 71 and the third drive member 75 to the second fixed plate 62 of the fixing frame 6, forming a stable support structure.

[0039] The third driving component 75 can be a geared motor assembly, with toothed grooves on the outer side of the rotating ring 72 meshing with the gears, and the rotation of the gears driving the rotating ring 72 to rotate; the third driving component 75 can also be a push rod, pushing the rotating ring 72 to rotate relative to the base plate 71. The third driving component 75 can also be other structures capable of driving the rotating ring 72 to rotate, including but not limited to the two driving structures mentioned above.

[0040] See Figure 6 In this embodiment, the mechanism for precisely controlling the amount of medication dispensed uses a second drive component 51, which is a second motor 511. The second motor 511 is fixed to the third fixed plate 63 of the fixed frame 6. The output end of the second motor 511 is threadedly connected to the lifting rod 52, and the lifting rod 52 is moved up and down by rotation. The electric push rod pushes the lifting rod 52 to move up and down. Compared with traditional lifting structures, this threaded connection drive method is smoother in operation, has less noise, and reduces the impact of vibration transmitted to the lifting rod 52, making it more suitable for use in quiet and stable home and medical environments.

[0041] See Figure 6In this embodiment, the mechanism for precisely controlling the amount of drug output includes a first fixed plate 61, a second fixed plate 62, and a third fixed plate 63 arranged vertically. The third fixed plate 63 has a hollow structure to facilitate the drug falling out. The fixing frame 6 also includes a side guard plate 64 and a fixing column 65, both of which are connected to the first fixed plate 61, the second fixed plate 62, and the third fixed plate 63. A first motor 311 is fixed to the side guard plate 64. The first fixed plate 61, the second fixed plate 62, and the third fixed plate 63 are arranged vertically in sequence. Supported by the fixing column 65 and the side guard plate 64, the entire fixing frame 6 forms a stable vertical support structure. This design effectively reduces the displacement of the equipment due to vibration during operation, improving the stability and reliability of drug output. The addition of the side guard plate 64 and the fixing column 65 provides additional support and protection for the fixing frame 6, enhancing the compressive strength and structural rigidity of the entire mechanism. The third fixing plate 63 adopts a hollow structure, allowing the medication to fall directly from it, reducing obstruction during the descent. The vertical layout and hollow design save space, making the device compact and moderately sized, which helps in miniaturization and makes it suitable for promotion in home and medical settings, facilitating user operation and mobility.

[0042] See Figure 7 , Figure 8 and Figure 9The intelligent medicine box of this embodiment includes a box body 1. Inside the box body 1 is a mechanism for precisely controlling the quantity of medicine output, as described above. A recognition component 8 is located at the top of the box body 1. The recognition component 8 includes a recognition platform 81 and a collector 82. The collector 82 collects information about the medicine on the recognition platform 81. A slide 9 is located below the recognition platform 81. By rotating the recognition platform 81, the medicine slides from the slide 9 into the medicine box 2. Multiple mechanisms are present. A first support 11 is located inside the box body 1. Multiple mechanisms are spaced apart on the first support 11. The first support 11 is rotatably mounted relative to the box body 1. Rotating the first support 11 connects a specific medicine box 2 to the slide 9. By collecting information about the medicine on the recognition platform 81 through the collector 82, precise identification of information such as the type and size of the medicine is achieved. This not only provides accurate parameters for subsequent medicine output but also matches the set dosage and administration time, improving the intelligence level of the device. Opening the recognition platform 81 guides the identified medicine along the slide 9 to the medicine box 2, avoiding jamming and deviation during the medicine's transport. Multiple mechanisms on the first support 11, precisely controlling the amount of medication dispensed, are rotatably mounted relative to the box body 1. This allows the smart medicine box to rotate the first support 11 as needed, aligning the designated medicine box 2 with the slide 9 to ensure accurate medication placement and prevent dispensing errors. These mechanisms are spaced apart on the first support 11 and dispense medication by rotating the support. This embodiment of the smart medicine box can hold four different types of medication. Users only need to set information for the four types of medication and a dispensing plan; the smart medicine box automatically identifies, aligns, and dispenses the medication, greatly reducing the user's workload. It is particularly suitable for elderly users or users requiring multiple medications.

[0043] See Figure 8 and Figure 9 The smart medicine box in this embodiment also includes a fourth motor 10. A second support 12 is also provided inside the box body 1, with a first support 11 located above the second support 12. The fourth motor 10 is fixed to the second support 12, and its output is connected to the first support 11 to drive the first support 11 to rotate relative to the box body 1, causing a specific medicine box 2 to align with the slide rail 9. The second support 12 has a hollow structure to facilitate the falling of medications. This ensures unobstructed sliding of medications from the upper medicine box, reducing congestion during dispensing and ensuring smooth medication flow. The fourth motor 10 enables automatic rotation of the first support 11, allowing the smart medicine box to flexibly switch between different medicine boxes. Users do not need to manually adjust the position of the medicine boxes, greatly simplifying the operation process, especially suitable for users who need to manage multiple medications.

[0044] See Figure 8In this embodiment, the smart medicine box has a lid 13 on top. Rotating the lid 13 opens the box 1, and placing a pill on the recognition platform 81 allows the collector 82 to acquire relevant parameter information. Then, rotating the recognition platform 81 opens the slide 9, transferring the identified medication to the designated medicine box 2. Through precise adjustment and control by the adjusting assembly 3, the adjusting assembly 7, and the control assembly 5, a specified number of medications in the medicine box 2 fall into the medicine dropping area 14, and the drawer 15 is pulled out to retrieve the medication to be taken.

[0045] The control method of this embodiment is applied to the smart medicine box described above. The control method includes the following steps: First step: Obtain the diameter n of the medicine through the identification component 8; Second step: Rotate the first support 11 to align a medicine box 2 with the slide 9; Third step: Open the identification platform 81 to allow the medicine to slide into the aligned medicine box 2 through the slide 9; Fourth step: Adjust the diameter of the channel 4 to match the diameter n of the medicine; Fifth step: The second drive component 51 drives the lifting rod 52 to rise within the channel 4 until the distance between the end of the lifting rod 52 and the opening 34 is N, and 0.5n < N < 1.5n, so that the medicine falls from the opening 34. To prevent the next medication from slipping out, the following steps are taken: Sixth step: Control the first drive unit 31 to drive the turntable 32 to rotate, causing the blades 33 to rotate and adjusting the size of the opening 34 formed by the blades 33 to accommodate the medication diameter n; Seventh step: A single medication falls from the opening 34, is held by the lifting rod 52, and is clamped within the channel 4, closing the opening 34 and controlling the lifting rod 52 to descend, releasing the single medication; Eighth step: After recognizing the single medication falling, the lifting rod 52 rises again, opening the opening 34, holding the next medication, closing the opening 34 again, and lowering the lifting rod 52, repeating the operation until the number of medications output reaches the predetermined value. Through automated recognition, rotation, adjustment, and output control, this smart medicine box can achieve medication dispensing without human intervention, reducing the complexity and burden of user operation.
