[0027] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0028] See also Figures 1-11 In an embodiment of the present invention, a pediatric medicine grinder comprises: A machine base 1, on which a grinding cylinder 2 is mounted, and on which a detachable grinding cover 3 is mounted; The base 1 is provided with a driving rod 15 and a stabilizing component. When the driving rod 15 rotates, the stabilizing component is activated to improve the placement stability of the base 1. Preferably, see Figure 3 、 Figure 10 A support frame 102 is fixedly installed in the above-mentioned base 1, and a motor is fixedly installed on the support frame 102. The motor is connected to a driving rod 15 rotatably installed in the base 1 through a belt, and the driving rod 15 is inserted into the grinding cylinder 2 at one end and coaxially fixed with a grinding knife 10. After starting the motor, the motor output shaft that continuously rotates in the same direction can drive the driving rod 15 to rotate in the same direction at high speed. Then, the grinding knife 10 that rotates synchronously with the driving rod 15 can crush and grind the medicine placed in the grinding cylinder 2, thereby producing powder so that children can better absorb the medicine.

[0029] The stabilizing assembly includes a driving structure and an adsorption structure. The driving structure includes a sliding rod 13 fixedly arranged on the driving rod 15. The sliding rod 13 is equidistantly arranged in two groups along the circumferential direction of the driving rod 15. A sliding sleeve 16 is slidably provided on each group of the sliding rods 13. The two groups of sliding sleeves 16 are respectively connected to a sleeve 19 sleeved on the driving rod 15 through a hinge rod 17. A first spring 18 is also slidably provided on the driving rod 15. One end of the first spring 18 abuts against the sleeve 19, and the other end abuts against a baffle formed on the driving rod 15. In particular, see Figure 3 、 Figure 10 The above-mentioned first spring 18 is always in a compressed state. The first spring 18 in the compressed state pushes the sleeve tube 19 away from the slide rod 13. At this time, under the connection action of the fixed-length hinge rod 17, the sleeve tube 19 away from the slide rod 13 can pull the two sets of sliding sleeves 16 closer to each other. When the motor enters the working state and drives the drive rod 15 to rotate continuously in the same direction, the two sets of sliding sleeves 16 can move away from each other along the axial direction of the slide rod 13 under the action of centrifugal force. In this process, the two sets of sliding sleeves 16 moving away from each other can be connected by the fixed-length hinge rod 17, thereby pulling the sleeve tube 19 toward the slide rod 13. At the same time, the rising sleeve tube 19 can drive the adsorption structure to move, thereby increasing the adsorption force between the machine base 1 and the placement plane, so as to improve the placement stability of the machine base 1 when performing the grinding operation, and then realize locking between the machine base 1 and the placement platform, to prevent the machine base 1 from moving on the placement plane due to grinding shaking when the machine base 1 is performing the medicine grinding.

[0030] For details, please refer to Figure 3 、 Figure 11 The adsorption structure includes a support member and a suction member. The support member includes a piston cylinder 14 fixedly arranged on the machine base 1. The piston cylinder 14 passes through the machine base 1, and a suction cup seat 1401 is fixedly arranged on one end protruding from the machine base 1. The suction member includes a collar 27 rotatably connected to the sleeve 19. The collar 27 is provided with multiple sets of fixed rods 2701 equidistantly along its circumference. A piston rod 28 is fixedly provided at one end of the fixed rod 2701 away from the collar 27. The piston rod 28 is in sealing and sliding connection with the piston cylinder 14. Preferably, the piston cylinder 14 is equidistantly arranged in three groups along the circumferential direction of the base 1. In combination with the above, in the initial state, under the action of the elastic potential energy stored in the first spring 18, the sleeve cylinder 19 away from the slide rod 13 can cause the piston rod 28 to be located at the end close to the suction cup seat 1401. When using the device for drug grinding, the base 1 needs to be placed in a fixed position (i.e., a placement platform). During the placement process, the base 1 is pressed toward the placement platform, which can fully eliminate the control of the suction cup seat 1401 and the piston cylinder 14, so that the suction cup seat 1401 can fully contact the placement platform, thereby fixing the base 1 on the placement platform, facilitating subsequent grinding, and preventing sliding between the base 1 and the placement platform. When the driving rod 15 is driven by the motor to rotate, the ring 27 rises with the sleeve 19, which can drive the piston rod 28 to rise relative to the piston cylinder 14, so that a negative pressure state is formed in the piston cylinder 14, thereby increasing the adsorption force between the suction cup seat 1401 and the placement plane, so as to reduce the possibility of shaking of the machine base 1 when the grinder is grinding medicine.

[0031] For further information, see Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 , the grinding cover 3 is provided with a rotating rod 5 and a lifting structure, the rotating rod 5 is sleeved with a lifting sleeve 7, the lifting sleeve 7 has multiple groups of scraping members equidistantly arranged along its circumferential direction, the scraping members are connected to the lifting members sleeved on the lifting sleeve 7, and during the rotation of the driving rod 15, the lifting structure can drive the lifting sleeve 7 to move up and down relative to the rotating rod 5, and during the lifting of the lifting sleeve 7, the lifting member cooperates with the suction component provided on the grinding cover 3 to drive the multiple groups of scraping members to contract or expand toward the rotating rod 5, thereby scraping off the medicine adhered to the inner wall of the grinding cylinder 2; For additional information, please refer to Figure 3 、 Figure 7The end of the grinding knife 10 away from the machine base 1 is coaxially fixed with a docking post 12, and the docking post 12 is equidistantly provided with two groups of alignment rods 1201 along its circumferential direction, and the end of the rotating rod 5 away from the grinding cover 3 is coaxially fixed with a docking cylinder 501, and the inner wall of the docking cylinder 501 is equidistantly provided with two groups of alignment grooves 502 along its circumferential direction, and the alignment grooves 502 are adapted to the alignment rods 1201. When performing drug grinding, the grinding material to be ground is first added into the grinding cylinder 2 (be careful not to cover the docking post 12 when adding the drug), and then the driving rod 15 is aligned with the rotating rod 15 under the cooperation of the docking post 12 and the docking cylinder 501. The movable rod 5 is coaxially connected. At this time, the grinding cover 3 cooperates with the grinding cylinder 2 to form a closed environment inside the grinding cylinder 2. Then, the start-stop switch 101 is pressed, and the motor enters the working state, which can drive the driving rod 15 and the grinding knife 10 to rotate at high speed, thereby grinding and crushing the grinding material. At the same time, with the cooperation of the docking cylinder 501 and the docking column 12, the rotating grinding knife 10 can drive the rotating rod 5 to rotate synchronously. Subsequently, the rotating rod 5 can drive the lifting structure to move, and then drive the scraper to scrape the inner wall of the grinding cylinder 2, thereby scraping off the medicine adhering to the inside of the grinding cylinder 2, and re-contacting the grinding knife 10 for further crushing.

[0032] The lifting structure includes a rotating rod 6 rotatably mounted on the grinding cover 3, a lifting ring 20 is sleeved on the rotating rod 6, the lifting ring 20 is fixed to the lifting sleeve 7, and a protrusion 2001 is formed on the inner wall of the lifting ring 20. The protrusion 2001 is slidably disposed in a closed groove 601 formed on the outer wall of the rotating rod 6, and the closed groove 601 is a spiral groove; For details, please refer to Figure 7 A first linkage wheel 25 is coaxially fixed on the rotating rod 6, and the first linkage wheel 25 is connected to a second linkage wheel 26 coaxially fixed on the rotating rod 5 through a linkage belt. In particular, the radius of the first linkage wheel 25 is multiple times the radius of the second linkage wheel 26, so that the second linkage wheel 26 can only drive the first linkage wheel 25 to rotate one circle when following the rotating rod 5 to rotate multiple circles.

[0033] The lifting member includes a movable sleeve 8 sleeved on the lifting sleeve 7, and a magnetic piece 23 is fixedly provided on the movable sleeve 8. The magnetic piece 23 is provided on the side of the movable sleeve 8 and protrudes from the movable sleeve 8; The scraper includes an arc-shaped plate 9, and a plug-in cylinder 901 is fixedly provided on the side of the arc-shaped plate 9 facing the lifting sleeve 7. The plug-in cylinder 901 is slidably connected to the plug-in rod 701 fixedly provided on the lifting sleeve 7, and each group of the plug-in cylinders 901 is connected to the movable sleeve 8 through a connecting rod 22; Preferably, see Figure 2、 Figure 4 、 Figure 5 、 Figure 6 , the above-mentioned arc-shaped plates 9 are arranged in four groups at equal intervals along the circumferential direction of the lifting sleeve 7, and a second spring 21 is also slidably provided on the above-mentioned lifting sleeve 7, one end of the second spring 21 abuts against the magnetic piece 23, and the other end abuts against the movable sleeve 8, and the above-mentioned second spring 21 is always in a compressed state. The second spring 21 in the compressed state pushes the movable sleeve 8 to move toward the plug-in rod 701. In particular, in the initial state, the circular structure formed by the four groups of arc-shaped plates 9 has the largest radius, and the maximum radius is just equal to the inner diameter of the grinding cylinder 2; In combination with the above, when the driving rod 15 rotates continuously in the same direction, the rotating rod 5 connected to the driving rod 15 can drive the rotating rod 6 to rotate synchronously, and in the process of the rotating rod 6 rotating one circle, the contact and extrusion of the groove wall of the closed groove 601 on the protrusion 2001 can force the lifting ring 20 to rise and fall along the axial direction of the rotating rod 6. During this process, the attraction component is triggered, so that the lifting ring 20 drives the lifting sleeve 7 to rise, and the four groups of curved plates 9 shrink toward the rotating rod 5, driving the curved plates 9 to separate from the inner wall of the grinding cylinder 2. When the lifting sleeve 7 descends, the four groups of curved plates 9 expand outward and fit into the inner wall of the grinding cylinder 2. As the lifting sleeve 7 descends, the curved plates 9 fit into the inner wall of the grinding cylinder 2 can scrape the inner wall of the grinding cylinder 2 to avoid the drug adhering to the inner wall during the grinding process, which leads to insufficient drug grinding.

[0034] For further information, see Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 The attraction component includes a magnetic attraction structure and a shielding structure. The magnetic attraction structure includes a strong magnet 24 fixedly arranged on the grinding cover 3. The strong magnet 24 can attract the magnetic sheet 23 fixedly arranged on the movable sleeve 8; wherein, the strong magnet 24 corresponds to the magnetic sheet 23.

[0035] The shielding structure includes a mounting plate 11 fixedly connected to the lifting sleeve 7 and a movable plate 4 slidably disposed on the grinding cover 3. A protruding post 1101 is fixedly disposed on the mounting plate 11. The protruding post 1101 is slidably disposed in a fitting groove provided on the movable plate 4. The protruding post 1101 is disposed on a side of the mounting plate 11. For details, please refer to Figure 8 、 Figure 9The above-mentioned movable plate 4 is arranged in an "L"-shaped structure, including a shielding plate 405, and a slider 404 is fixedly provided on the side of the shielding plate 405 facing the grinding cover 3. The slider 404 is slidably arranged in a slide groove opened on the grinding cover 3. Under the cooperation between the slider 404 and the slide groove, the movable plate 4 can only slide along the width direction of the movable plate 4.

[0036] The interlocking groove includes a vertical groove 401, an oblique groove 402, and a reset groove 403 formed on the movable plate 4. Blocking members are provided at the junctions between the oblique groove 402, the vertical groove 401, and the reset groove 403. These blocking members include a deflection plate 29 and a spring clip 30. Two sets of deflection plates 29 are located in the vertical groove 401 and the reset groove 403, respectively. The deflection plate 29 in the vertical groove 401 is elastically deflected in the vertical groove 401 by the spring clip 30, while the deflection plate 29 in the reset groove 403 is elastically deflected in the reset groove 403 by another spring clip 30. With the cooperation of the blocking members, the protrusion 1101 can only slide in a certain direction within the interlocking groove, thereby driving the movable plate 4 to move and shield the strong magnet 24. See also Figure 9The barrier member includes a deflection plate 29 and a spring piece 30. In the initial state, under the cooperation of the spring piece 30, the two sets of deflection plates 29 are respectively kept parallel to the vertical groove 401 and the reset groove 403, and the mounting plate 11 is provided with a through groove 1102. By providing the through groove 1102, the mounting plate 11 can be prevented from blocking the magnetic sheet 23. In combination with the above, in the initial state, the protruding column 1101 is located at the junction of the oblique groove 402 and the reset groove 403, and the shielding plate 405 is not The strong magnet 24 is shielded. At this time, due to the attraction of the strong magnet 24 to the magnetic sheet 23, the arc plate 9 is in an inward contraction state, and the lifting ring 20 is away from the grinding cover 3. When the rotating rod 5 is driven by the driving rod 15 to rotate, the rotating rod 6 can drive the lifting ring 20 to rise under the cooperation of the closed groove 601 and the protrusion 2001. During this process, the protrusion 1101 can slide along the reset groove 403. During the sliding process, the contact and extrusion generated by the protrusion 1101 on the groove wall of the reset groove 403 can force The movable plate 4 is moved closer to the rotating rod 5 along the width direction. At this time, the shielding plate 405 will gradually shield the strong magnet 24, so that the attraction of the strong magnet 24 to the magnetic sheet 23 will gradually decrease. Driven by the elastic potential energy stored in the second spring 21, the movable sleeve 8 will descend relative to the lifting sleeve 7. At the same time, under the connection of the fixed-length connecting rod 22, the movable sleeve 8 will push the arc plate 9 to slowly expand outward until the protruding column 1101 contacts the upper deflection plate 29 (the vertical groove 401 and the reset groove 40 3), the protruding post 1101 that rises with the lifting sleeve 7 pushes the deflection plate 29 toward the vertical slot 401, causing the spring 30 to elastically deform. When the lifting sleeve 7 moves to the highest point, the protruding post 1101 engages with the vertical slot 401, and the deflection plate 29 returns to its initial state under the drive of the spring 30. At this time, the shielding plate 405 completely shields the strong magnet 24, and the movable sleeve 8, driven by the second spring 21, pushes the curved plate 9 to fit the inner wall of the grinding cylinder 2; Subsequently, the rotating rod 6 drives the lifting ring 20 and the lifting sleeve 7 to descend. During this process, the protruding post 1101 slides along the vertical groove 401, and the shielding plate 405 continues to keep shielding the strong magnet 24. The curved plate 9 will remain in the maximum opening state. As the lifting sleeve 7 descends, the curved plate 9 can scrape the inner wall of the grinding cylinder 2, scraping off the medicine adhering to the inner wall of the grinding cylinder 2 so that it can contact the grinding knife 10 again. Until the protruding post 1101 is combined with the inclined groove 402, the lifting sleeve 7 continues to descend, causing contact and extrusion between the protruding post 1101 and the wall of the inclined groove 402, which can force the movable plate 4 to move away from the rotating rod 5 in the width direction, thereby driving the shielding plate 405 to slowly expose the strong magnet 24 At this time, the strong magnet 24 will attract the magnetic sheet 23 through the through slot 1102, so that the arc plate 9 retracts inward until the protruding post 1101 contacts the lower deflection plate 29. The deflection plate 29 that continues to slide along the inclined slot 402 will force the deflection plate 29 to deflect toward the reset slot 403. When the lifting sleeve 7 drops to the lowest point, the protruding post 1101 returns to its initial state, and the deflection plate 29 returns to its initial state under the drive of the spring 30. At this time, the strong magnet 24 is completely exposed, and the attraction of the magnetic sheet 23 completely separates the arc plate 9 from the inner wall of the grinding cylinder 2. Then, the above process is repeated, so that during the grinding process, the medicine will not adhere to the inner wall of the grinding cylinder 2, thereby causing insufficient grinding and insufficient accuracy of the medicine dosage.
