DETAILED DESCRIPTION

[0036] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The tablet rapid grinding device provided in this embodiment is mainly used to solve the problem that many existing tablet grinding devices are bulky and complex in design, and usually need to be fixed in a specific position for use, which limits their portability and applicability in different environments. For users who need to use these devices at home, in hospitals or while traveling, this inconvenience is a significant problem; secondly, although some miniaturized tablet grinding devices have solved the portability problem to a certain extent, in actual use, their grinding efficiency and uniformity are not ideal, and some devices often perform grinding and scraping operations simultaneously during the grinding process, resulting in the grinding roller being unable to effectively grind the tablets into fine powder. This design defect not only affects the quality and uniformity of the powder, but may also have a negative impact on the efficacy of the drug, and provides the following technical solutions, which will be combined with Figure 1-Figure 9 Make a detailed description:

[0038] The tablet rapid grinding device of the present invention provides users with a new tablet processing solution with its exquisite design and convenient operation mode. The device includes a cylindrical medicine box 1, a chopping mechanism 2, a grinding mechanism 3 and a scraping mechanism 4, wherein:

[0039] The medicine box 1 is composed of an upper box body 11, a lower box body 12 and a fixing assembly 13. The opening end of the lower box body 12 is movably inserted into the opening end of the upper box body 11. The fixing assembly 13 is installed on the upper box body 11 and is used to fix the upper box body 11 and the lower box body 12. A medicine placing port 14 is formed through the upper box body 11 to facilitate users to put in tablets. A grinding plate 15 is fixed inside the lower box body 12 to provide a solid foundation for the grinding process.

[0040] The shredding mechanism 2 is mounted on the upper box body 11 and is used to shred the tablets;

[0041] The grinding mechanism 3 is mounted on the lower box body 12 and is used to grind the chopped tablets on the grinding plate 15;

[0042] The scraping mechanism 4 is arranged on the lower box body 12 and is used to scrape the powder adhered to the grinding plate 15. When the upper box body 11 and the lower box body 12 are fixed, the scraping mechanism 4 does not contact the grinding plate 15. When the upper box body 11 and the lower box body 12 are separated, the scraping mechanism 4 contacts the grinding plate 15.

[0043] At the beginning of the operation, the user only needs to put the tablets into the medicine dispensing port 14 of the upper box body 11, and then use the shredder mechanism 2 to shred the tablets. The ingenious design of the shredder mechanism 2 ensures that the tablets can be quickly and evenly cut into small pieces, ready for the next grinding step. Then, the grinding mechanism 3 of the device starts to work. The grinding mechanism 3 installed on the lower box body 12 performs a fine grinding process on the shredded tablets on the grinding plate 15, so that the tablets are converted into a powder state that is easy to take or further processed.

[0044] After the grinding is completed, the user only needs to separate the upper box body 11 from the lower box body 12, and the scraping mechanism 4 will start to work. The design of the scraping mechanism 4 is very user-friendly. When the upper box body 11 is separated from the lower box body 12, it can automatically contact the grinding plate 15 and easily scrape off the medicine powder attached thereto. This step not only simplifies the cleaning process, but also avoids the waste of medicine powder and the risk of cross contamination. When it is necessary to continue grinding, the user only needs to re-fix the upper box body 11 and the lower box body 12, and the scraping mechanism 4 will leave the grinding plate 15 and will not interfere with the grinding process.

[0045] The entire operation process is simple and intuitive, without the need for complicated steps or additional tools, making the tablet grinding process fast, efficient and clean. This design not only improves the quality of the powder, but also makes the cleaning and maintenance of the device easy, greatly improving the user experience.

[0046] For details, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 The shredding mechanism 2 includes a cutting blade net 21, a pressing plate 22, a control rod 23 and a control board 24. The cutting blade net 21 is fixed on the inner wall of the upper box body 11 and is located below the medicine release port 14, providing a necessary cutting surface for shredding the tablets. The control rod 23 is movably inserted on the end of the upper box body 11 facing away from the opening. The pressing plate 22 is movably arranged inside the upper box body 11 and fixed to one end of the control rod 23. The control board 24 is fixed to the other end of the control rod 23. Such a design enables the pressing plate 22 to move up and down under the drive of the control rod 23 to achieve the shredding action of the tablets.

[0047] During operation, the user controls the operation of the entire shredding mechanism 2 through the control panel 24. After the tablets are placed in the medicine outlet 14, the pressure plate 22 applies downward pressure through the push of the control rod 23, forcing the tablets to contact the cutting blade net 21, thereby achieving shredding. This design not only ensures the high efficiency of the shredding process, but also ensures the simplicity and safety of operation. Through the coordinated action of the control rod 23 and the control panel 24, the user can easily control the shredding process without the need for additional tools or complicated operating steps. The design of the entire shredding mechanism 2 is compact and efficient, providing an ideal pretreatment for the rapid grinding of tablets, and also reflects the careful consideration of the present invention in improving user experience.

[0048] Furthermore, a plurality of push blocks 221 are constructed on one side of the pressure plate 22 facing the cutting blade net 21, and the plurality of push blocks 221 correspond one-to-one to the plurality of mesh holes on the cutting blade net 21. The advantage of the design of the push blocks 221 is that when the shredded tablets are stuck in the mesh holes of the cutting blade net 21, the push blocks 221 can push the stuck tablets into the lower box body 12, thereby achieving an efficient and uniform shredding effect.

[0049] A spring 25 sleeved on the control rod 23 is connected between the end of the upper box body 11 and the control board 24. The addition of the spring 25 provides necessary elastic support for the shredding mechanism 2, so that the pressure plate 22 can apply pressure smoothly during the shredding process and quickly reset after the shredding is completed, thereby improving the response speed of the shredding and the durability of the mechanism.

[0050] In the tablet rapid grinding device of the present invention, the design of the grinding mechanism 3 is the core of achieving fine grinding of tablets. Figure 2 , Figure 4 , Figure 6 , Figure 8 and Fig. 9 The grinding mechanism 3 includes a rotating rod 31 rotatably mounted on the end of the lower box body 12 facing away from the opening, one end of the rotating rod 31 movably penetrates the interior of the lower box body 12 and movably penetrates the grinding plate 15, one end of the rotating rod 31 is fixed with two evenly distributed connecting blocks 32, a grinding roller 33 is rotatably mounted on the connecting block 32, the outer peripheral side of the grinding roller 33 is close to one side of the grinding plate 15, ensuring that the grinding roller 33 can effectively contact and rub with the grinding plate 15 when rotating, and a knob 34 is fixed to the other end of the rotating rod 31, by rotating the knob 34, the user can easily control the grinding roller 33 to grind the tablets, so that the grinding process is both efficient and uniform.

[0051] In this example, see Figure 2 , Figure 4 , Figure 6 , Figure 8 and Fig. 9The scraping mechanism 4 includes a U-shaped plate 41 fixed on one end of the rotating rod 31 located inside the lower box body 12, and the two ends of the U-shaped plate 41 are fixed to the ends of the rotating rod 31. A mounting plate 42 is movably arranged in the opening of the U-shaped plate 41, allowing it to move freely in the U-shaped plate 41 to adapt to scraping needs under different conditions. Two scrapers 43 are fixed on one side of the mounting plate 42, and the two scrapers 43 are respectively located on the opposite sides of the U-shaped plate 41. Such a symmetrical design ensures the uniformity and comprehensiveness of the scraping action and can cover the entire surface of the grinding plate 15. In order to enable the scraper 43 to be close to the grinding plate 15 and effectively scrape off the powder, a spring 2 44 is cleverly connected between the side of the mounting plate 42 facing away from the rotating rod 31 and the inner wall of the U-shaped plate 41. The design of this spring 2 44 not only provides the scraper 43 with the necessary elasticity so that it can adapt to the grinding plates 15 of different hardness, but also ensures the stability and consistency of the scraper 43 during the scraping process. The scraping mechanism 4 also includes an adjusting member 45;

[0052] When the user needs to scrape off the medicine powder attached to the grinding plate 15, the upper box body 11 is separated from the lower box body 12. At this time, under the elastic force of the spring 2 44, the mounting plate 42 is pushed to move until one side of the scraper 43 is in contact with the grinding plate 15. At this time, the opening of the lower box body 12 is aligned with the medicine receiving tool, and the knob 34 is turned to drive the scraper 43 to rotate, so that the medicine powder can be scraped off to the inside of the medicine receiving tool.

[0053] For further information, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The adjusting member 45 includes a device ring 451 fixed on the inner wall of the upper box body 11, and an annular groove 452 is constructed on the inner wall of the device ring 451. The top and bottom sides of the inner wall of the device ring 451 are both rounded. The adjusting member 45 also includes a device rod 453 fixed on the scraper 43, and a clamping ball 454 is fixed on the device rod 453. When the opening end of the upper box body 11 is completely sleeved on the opening end of the lower box body 12, the clamping ball 454 is movably clamped in the inner part of the annular groove 452, ensuring the correct position and function of the scraping mechanism 4. When the upper box body 11 is slightly away from the lower box body 1 2, the ball 454 overcomes the elastic force of the spring 44 to prevent one side of the scraper 43 from being in contact with the grinding plate 15. This ingenious mechanism allows the user to easily separate the upper box body 11 and the lower box body 12 when necessary to collect the powder or clean the device. In addition, the fixing component 13 can fix the upper box body 11 and the lower box body 12 at this time, ensuring the stability and safety during the grinding process. The design of the adjustment member 45 not only provides a simple way to adjust the contact between the scraper 43 and the grinding plate 15, but also enhances the overall operability and flexibility of the device.

[0054] The design of the adjustment member 45 is an important innovation in the present invention. Through the coordinated action of the device ring 451, the device rod 453 and the locking ball 454, it provides the user with an intuitive, flexible and reliable adjustment mechanism.

[0055] In the tablet rapid grinding device of the present invention, the design of the fixing assembly 13 is crucial, which ensures the stable connection between the upper box body 11 and the lower box body 12, and also provides a simple fixing and unlocking mechanism, see Figure 3 , Figure 6 and Figure 7 The fixing assembly 13 includes a positioning groove 131 constructed on the outer wall of the lower box body 12 and arranged along the length direction of the lower box body 12. One end of the positioning groove 131 passes through the open end of the lower box body 12. A positioning block 132 is fixed on the inner wall of the open end of the upper box body 11. The positioning block 132 is slidably installed inside the positioning groove 131, so that it can be ensured that the open end of the upper box body 11 can be smoothly sleeved on the open end of the lower box body 12. The fixing assembly 13 also includes a fixing iron block 133 fixed on the outer side of the upper box body 11. A fixing hole 134 is constructed on the outer side of the lower box body 12. A fixing rod 135 is movably inserted on the fixing iron block 133. The fixing rod 135 One end of the fixing rod 135 movably penetrates the upper box body 11, and a magnet sheet 136 is fixedly sleeved on the fixing rod 135. When the magnet sheet 136 is adsorbed on the fixing iron block 133, one end of the fixing rod 135 is movably inserted into the fixing hole 134, so that the upper box body 11 and the lower box body 12 are firmly fixed together. This fixing mechanism using magnetic force not only provides a fast and stable fixing method, but also simplifies the assembly and disassembly process of the device. In this way, the user can easily separate the upper box body 11 from the lower box body 12 to collect the powder or clean the device, while also ensuring the stability and safety of the device during the grinding process.

[0056] Furthermore, a slot 137 is constructed on one side of the fixed iron block 133, and the magnet piece 136 is located inside the slot 137. This design not only protects the magnet piece 136 and prevents it from falling off or moving during use, but also ensures the stable output of magnetic force. The existence of the slot 137 enables the magnet piece 136 to fit closely with the fixed iron block 133. When the upper box body 11 and the lower box body 12 need to be fixed, the magnet piece 136 can be reliably adsorbed on the fixed iron block 133, thereby achieving a stable connection between the upper box body 11 and the lower box body 12. In addition, the design of the slot 137 also takes into account aesthetics and integrity, so that the magnet piece 136 appears hidden and exquisite in the fixing component 13.

[0057] For further information, see Figure 6 and Figure 7An opening and closing ring 111 is rotatably sleeved on the outer peripheral side of the upper box body 11, and a corresponding port 112 corresponding to the medicine release port 14 is penetrated on the opening and closing ring 111. Such a design means that when the user puts in the tablets, the position of the medicine release port 14 can be directly observed through the corresponding port 112 to ensure that the tablets are accurately placed in the device. When not in use, the opening and closing ring 111 is rotated so that the corresponding port 112 does not correspond to the medicine release port 14, and the interior of the medicine box 1 is sealed to ensure cleanliness and avoid contamination.

[0058] When the device in this scheme is used:

[0059] The user first puts the tablets into the upper box body 11 through the medicine outlet 14, and then the tablets fall onto the pressing plate 22 above the cutting blade net 21. Through the operation of the control panel 24, the control rod 23 drives the pressing plate 22 to move up and down, so that the tablets contact the cutting blade net 21 and are shredded. In this process, the spring 1 25 provides the necessary elastic support for the shredding mechanism 2 to ensure the uniformity of shredding and the smooth return of the pressing plate 22.

[0060] The chopped tablets fall onto the grinding plate 15 inside the lower box body 12. At this time, the user rotates the knob 34 to drive the grinding roller 33 on the rotating rod 31 to rotate, and the tablets on the grinding plate are finely ground. The contact between the grinding roller 33 and the grinding plate 15 realizes the efficient conversion of tablets into powder.

[0061] After the grinding is completed, the user only needs to separate the upper box body 11 from the lower box body 12, and the scraping mechanism 4 will start to work. Under the action of the spring 44, the scraper 43 contacts the grinding plate 15. At this time, the user can align the lower box body 12 with the medicine receiving tool, and by turning the knob 34, the scraper 43 is driven to collect the medicine powder into the medicine receiving tool.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
