[0002] A pediatric tablet grinding device is a device designed specifically for pediatric medication needs and used to grind tablets into a powder. In pediatric treatment, because children's swallowing ability is not yet fully developed and they find it difficult to swallow whole tablets directly, tablets often need to be ground into powder and mixed with food or drinks to assist children in taking medication. Common methods include using a crushing mechanism to crush tablets through pressure; setting up a crushing mechanism to first break larger tablets into small pieces for subsequent further grinding; and grinding tablets into powder by rubbing against a rotating grinding disc. These methods are designed to efficiently, conveniently, and safely convert tablets into a powder form suitable for children.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1, as Figure 1 、 Figure 2 and Figure 3 As shown, a pediatric tablet grinding device includes a shell 1, a cover plate 5 is rotatably connected to the upper end of the shell 1, a controller 2 is fixedly installed on one side of the upper end of the shell 1, a buckle 4 is fixedly installed on the cover plate 5 and the front end of the shell 1, a grinder 6 is provided in the inner cavity of the shell 1, a finished product drawer 3 is slidably connected to the bottom wall of the inner cavity of the shell 1, a clean water tank 11 connected to the grinder 6 is provided on one side of the inner cavity of the shell 1, and a sewage tank 12 connected to the bottom wall of the inner cavity of the shell 1 is provided on one side of the inner cavity of the shell 1.

[0035] The above-mentioned clean water tank 11 and sewage tank 12 are both equipped with micro water pumps. The clean water tank 11 sends clean water into 6, and the sewage tank 12 recovers the cleaned sewage from the bottom, which is convenient for subsequent use and reduces cross contamination. This structure belongs to the conventional technical means in the prior art and will not be further demonstrated and explained in the present invention.

[0036] Further, in order to realize the crushing and grinding of tablets, see Figure 4 The grinder 6 includes a processing cylinder 61 fixedly connected to the inner cavity of the outer shell 1, a feeding structure 63 is provided on the upper part of the inner surface of the processing cylinder 61, a primary crushing structure 64 is provided in the middle part of the inner surface of the processing cylinder 61, a secondary crushing structure 65 is provided at the lower part of the inner surface of the processing cylinder 61, and a conical tube 62 is provided on the bottom wall of the inner surface of the processing cylinder 61.

[0037] During the operation of this embodiment, the tablets are guided into the primary crushing structure 64 by the feeding structure 63, and crushed by the action of the primary crushing structure 64. The materials are then fed into the secondary crushing structure 65 for further grinding and crushing through the cooperation of the primary crushing structure 64. At the same time, the drug powder agglomerated due to grinding is separated by the action of the secondary crushing structure 65 to form loose drug powder, which is convenient for feeding pediatric patients.

[0038] Further, to facilitate feeding the powder to pediatric patients, see Figure 5 The inner surface of the finished drawer 3 is symmetrically provided with rubber plates 31 , and the ends of the two rubber plates 31 close to each other are fixedly connected with a rubber connecting strip 32 .

[0039] It should be noted that the above-mentioned controller 2 is a conventional controller. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of controlling the motor in the grinder 6, and its internal structure, operating principle, wiring, and control method are no longer described in detail.

[0040] Embodiment 2: Based on embodiment 1, this embodiment realizes feeding tablets into the processing cylinder 61 in batches through the cooperation of the outer ring 631, the curved block 633 and the sliding plate 635 in the feeding structure 63, and utilizes the driving motor 661 and the bevel gear set 662 in the driving structure 66 to drive the grinding component 641, the grinding plate 644 and the like to rotate, completing the preliminary crushing and sorting, and through the sliding ring 6414, the limiting ring 6415, the blade 6411 and the pressure plate 6413 in the crushing component 641, in cooperation with the convex point 6441 on the grinding plate 644, the grinding operation of the tablets is realized, thereby realizing the orderly feeding, crushing and sorting of the tablets and improving the grinding efficiency and quality.

[0041] Specifically, in order to realize feeding the tablets to be ground into the processing cylinder 61 in batches, refer to Figure 6 The feeding structure 63 includes an outer ring 631 fixedly connected to the inner wall of the processing cylinder 61. Two curved blocks 633 are annularly distributed on the inner surface of the outer ring 631. The tail ends of the two curved blocks 633 are each provided with a discharge port 634. The inner surfaces of the discharge ports 634 are slidably connected with sliding plates 635. The lower end of the sliding plate 635 is provided with a friction column lower than the lower end of the outer ring 631. The inner arc surfaces of the two curved blocks 633 are jointly provided with a center column 632, and the inner surface of the center column 632 is fixedly installed with a driving structure 66.

[0042] When the medicine enters the inner side of the outer ring 631, it will slide on the surface of the curved block 633 until it enters the discharge port 634. When the grinding component 641 is in operation, it will pass through the sliding plate 635 and drive the sliding plate 635 to slide in the discharge port 634 through the friction column, thereby making the discharge port 634 connected to the bottom of the outer ring 631. At this time, the tablets will fall through the discharge port 634 into the preliminary crushing structure 64 below, thereby achieving uniform discharge following the grinding progress of the grinding component 641.

[0043] Further, in order to achieve the initial crushing of the tablets, see Figure 7 The preliminary crushing structure 64 includes a sliding groove 645 opened in the middle of the inner surface of the processing cylinder 61, and a grinding plate 644 is slidably connected to the inner surface of the sliding groove 645. A number of connecting grooves 642 connected to the lower part of the inner surface of the processing cylinder 61 are annularly distributed on the lower part of the inner surface of the sliding groove 645. A crushing assembly 641 is provided at the upper end of the grinding plate 644. The crushing assembly 641 and the grinding plate 644 are both connected to the driving structure 66 for transmission. A driving groove 643 is provided on the upper part of the inner surface of the processing cylinder 61.

[0044] Further, in order to drive the secondary crushing structure 65 and the primary crushing structure 64 to crush the tablets, refer to Figure 7 The driving structure 66 includes a driving motor 661 installed on the inner surface of the central column 632. A bevel gear set 662 is fixedly installed on the output end of the driving motor 661. The forward output gear of the bevel gear set 662 is transmission-connected to the crushing assembly 641. The inner surface of the reverse output gear of the bevel gear set 662 is fixedly connected to the driving shaft 663. The outer surface of the driving shaft 663 is transmission-connected to the grinding plate 644 and the secondary crushing structure 65.

[0045] By driving the bevel gear set 662 with the driving motor 661, the two output shafts of the bevel gear set 662 rotate in opposite directions, thereby driving the grinding components 641 and 664 to rotate in opposite directions. By driving the grinding plate 644, the drug particles on the upper side are moved into the surrounding sliding groove 645 by the centrifugal force generated by the rotation. At the same time, due to the obstruction of the lower edge of the driving groove 643, particles that have not been ground to the predetermined size cannot enter the sliding groove 645, thereby achieving preliminary grinding and sorting of the drug particles.

[0046] Furthermore, in order to realize the pressing of the tablets to slide on the grinding plate 644 and then grind the tablets, refer to Figure 8The crushing assembly 641 includes a sliding ring 6414 that is transmission-connected to the forward output gear of the bevel gear set 662. The lower end of the sliding ring 6414 is fixedly connected to a limit ring 6415 through a spring. The limit ring 6415 is rotatably connected to the upper end of the grinding plate 644. The outer surface of the crushing assembly 641 is annularly distributed and fixedly connected with two blades 6411 that are slidingly connected to the inner surface of the drive groove 643 through a pulley. A U-shaped groove 6412 is provided on the lower side of the inner surface of the two blades 6411 in the same direction of rotation. The inner surfaces of the two U-shaped grooves 6412 are slidingly connected to the compression plate 6413 through a spring rod. The sliding ring 6414 is slidingly connected to the outer surface of the drive shaft 663.

[0047] Further, in order to cooperate with the grinding component 641 to grind the tablets, see Figure 8 The upper end of the grinding plate 644 is fixedly connected with a number of protrusions 6441 distributed in an array, and the outer surface of the grinding plate 644 is fixedly connected with a number of brush plates 6442 distributed in an annular manner. The bottom ends of the brush plates 6442 are all provided with silicone strips.

[0048] The crushing assembly 641 disposed on the lower side of the bevel gear assembly 662 rotates under the action of the connecting groove 642, thereby driving the crushing assembly 641 to rotate. When the crushing assembly 641 passes under the driving groove 643, the sliding groove 645 is retracted into the driving groove 643 through the friction column, and the driving groove 643 is connected to the processing cylinder 61, so that the tablets fall onto the grinding plate 644.

[0049] Under the action of the limiting ring 6415, the pulley on the blade 6411 is always in contact with the upper inner surface of the driving groove 643. Under this premise, the running trajectory of the blade 6411 can be regarded as two groups and four sections, namely two arc-shaped trajectories and two U-shaped trajectories. These four trajectories are spliced ​​together to form a set of actions of compressing the tablets for friction crushing, rising and collecting new tablets.

[0050] When the sliding ring 6414 drives the blade 6411 to rotate, when the blade 6411 is in the arc track of the driving groove 643, the compression plate 6413 inside it will compress the tablet under the paralysis effect so that it fits with the protrusions 6441 on the grinding plate 644. Under the action of the protrusions 6441, the tablet is gradually rubbed into broken particles and gradually moves to the surroundings under the action of centrifugal force. It enters the sliding groove 645 and falls into the secondary crushing structure 65 below through the connecting groove 642 opened at the bottom of the sliding groove 645.

[0051] When the blade 6411 moves in the U-shaped track, the blade 6411 will gradually move to the uppermost part under the action of the limit ring 6415, and contact the friction column at the bottom of the sliding plate 635. The action of the friction column drives the discharge port 634 into the discharge port 634, thereby prompting the tablets to fall onto the grinding plate 644. Further, the blade 6411 gradually moves downward under the action of the driving groove 643, and then presses the tablets on the lower part of the compression plate 6413 to achieve compression and crushing.

[0052] Example 3: Based on Example 2, this example further achieves further crushing and screening of drug particles through the cooperation of the conical plate 651, the drive ring 652 and the screen 658 in the secondary crushing structure 65. The driving gear 6521 and the driven gear 6522 drive the grinding roller 653 to rotate, and the damping strip forms a differential speed to enhance the grinding effect. The scraper 654 scrapes the drug particles and makes them flow into the connecting port 651. Further, through the magnetic effect of the grinding roller 653 and the magnetic ball 656, the magnetic ball 656 hits the vibration groove 657 to generate vibration, which assists the screen 658 to disperse the drug clusters. By utilizing the synergy of various structures, the crushing effect and dispersion efficiency of the drug powder are improved.

[0053] Specifically, in order to further crush the drug powder and make it pulverized, refer to Figure 9 and Figure 10 The secondary crushing structure 65 includes a conical plate 651 fixedly connected to the inner wall of the processing cylinder 61, a driving ring 652 is provided in the middle of the upper end of the conical plate 651, and a screen 658 that is rotatably connected to the inner surface of the conical plate 651 is connected to the driving shaft 663. A plurality of oscillation grooves 657 are distributed in an annular manner on the inner side of the conical plate 651, and spokes 655 are fixedly connected to the inner surfaces of the plurality of oscillation grooves 657. A plurality of spokes 655 are fixedly connected to the side away from the driving ring 652 with magnetic balls 656. The magnetic balls 656 are in a suspended state when not subject to external force. A plurality of communication ports 6511 that are connected to the inner cavity of the conical plate 651 are distributed in an annular manner at the junction of the upper end of the conical plate 651 and the driving ring 652.

[0054] Further, to achieve further grinding and pulverization of drug particles, refer to Figure 9 and Figure 10The secondary crushing structure 65 also includes a driving gear 6521 which is rotatably connected to the top of the inner surface of the driving ring 652 and is transmission-connected to the driving shaft 663. The outer surface of the driving gear 6521 is symmetrically meshed with driven gears 6522. The inner surfaces of the two driven gears 6522 are fixedly connected with grinding rollers 653 which are rotatably connected to the driving ring 652 and fit with the upper end of the conical plate 651. The outer surface of the grinding roller 653 is provided with a magnetic strip whose magnetism is opposite to the magnetic pole of the magnetic ball 656. The outer surface of the driving ring 652 is annularly distributed and fixed with a number of scrapers 654 which fit with the upper end of the conical plate 651. A slot 6541 is provided on the side opposite to the rotation direction of the scrapers 654.

[0055] The drug particles fall onto the conical plate 651 through the connecting groove 642. At this time, the driving gear 6521 rotates under the action of the driving shaft 663, and the grinding roller 653 inside the driving ring 652 also rotates with the driving ring 652. A damping strip is provided at the connection between the grinding roller 653 and the conical plate 651 to block the rotation of the driving ring 652. However, this damping strip cannot completely restrict the rotation of the driving ring 652, so that a differential speed is formed between the driving ring 652 and the driving gear 6521. When the driving ring 652 drives the grinding roller 653 to rotate, the differential speed drives the grinding roller 653 to rotate on its own, further enhancing the grinding effect of the grinding roller 653 on the drug particles.

[0056] At the same time, a scraper 654 installed around the driving ring 652 scrapes off the drug particles and powder on the surface of the conical plate 651, causing them to slide downward along the inclined surface of the conical plate 651 and eventually flow into the connecting port 6511. From there, they enter the inner side of the screen 658 and are spread and further dispersed by the rotation of the screen 658.

[0057] During the rotation of the grinding roller 653, it will pass over each magnetic ball 656 and attract the magnetic balls 656 to move upward through magnetic action. When the grinding roller 653 leaves the range of the magnetic balls 656, the magnetic balls 656 rebound under the action of the spokes 655 and hit the inner surface of the oscillation groove 657, thereby generating oscillation, causing the powder particles on the screen 658 and the conical plate 651 to move downward, assisting the screen 658 in dispersing the drug clusters.
