[0002] Pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention and treatment of children. However, since children's physical development is not yet complete and their swallowing function is not as good as that of adults, it is difficult for them to take some tablets or capsules directly. A grinder is needed to grind the medicine into a fine powder suitable for children to improve the convenience and safety of children's medication.

[0003] In the prior art, a Chinese patent document with publication number CN111346012B proposes a grinding machine for pediatric medicine grinding, which includes a machine base and a machine body. A rotating motor is arranged in the machine base, a circular connecting seat is arranged at the bottom of the machine body, and the connecting seat is matched with the top of the machine base up and down. The machine body is provided with a grinding shaft, and the upper end of the grinding shaft extends into the machine body and is connected with a grinding knife. The lower end of the grinding shaft extends out of the machine body and is matched with the rotating shaft of the rotating motor up and down. A fixed seat is arranged at the top of the machine base, and a through hole of the fixed seat is arranged. A conical sleeve is sleeved on the outside of the rotating shaft, and the conical sleeve is located in the through hole. The fixed seat There are sliding grooves on the left and right sides respectively, and sliding rods are arranged in the sliding grooves. The lower part of the tapered sleeve extends downward to form a straight cylinder. A linear motor and a transmission member are arranged in the machine base. The transmission member connects the straight cylinder with the linear motor. The linear motor drives the straight cylinder to move up and down.

[0041] like Figure 2 , Figure 3 and Figure 8 As shown, the stabilizing unit includes a docking assembly 6 arranged inside the base 1 and a fixing assembly 7 arranged at the lower part of the base 1, the docking assembly 6 includes a docking hole 601 opened on the upper surface of the base 1, a docking rod 602 is fixedly connected to the lower surface of the grinding cylinder 2, the docking rod 602 is slidably engaged in the docking hole 601, a pin groove 608 is opened on the outer surface of the docking rod 602, a gear ring 603 is rotatably connected to the outer surface of the base 1, a gear 2 604 is rotatably connected inside the base 1, a shifting block 605 is fixedly connected to the upper surface of the gear 2 604, a hollow plate 606 is limited and slidably engaged in the hollow plate 606, a pin rod 607 is fixedly connected to the upper surface of the hollow plate 606, and the pin rod 607 is slidably connected to the inside of the pin groove 608;

[0042] The fixing assembly 7 includes a pressure rod 701 movably inserted into the lower surface of the base 1, the bottom end of the pressure rod 701 is fixedly connected to a suction cup 702, and the outer surface of the pressure rod 701 is sleeved with a spring 2 703;

[0043] The docking rod 602 is aligned with the docking hole 601 and inserted, and the grinding cylinder 2 is pressed to make its bottom fit with the upper surface of the base 1. In this way, the docking rod 602 will push the pressure rod 701, forcing the pressure rod 701 to squeeze the suction cup 702 and the spring 2 703. The suction cup 702 is adsorbed on the desktop by the squeezing and pressure of the pressure rod 701, thereby improving the stability of the base 1. Then the gear ring 603 is rotated. During the rotation of the gear ring 603, the gear 2 604 is driven to rotate, and then the shift block 605 is driven to make a circular motion around the center of the gear 2 604. Since the shift block 605 slides in the hollow plate 606, the hollow plate 606 is driven to make a linear motion. In this way, the pin rod 607 is driven to move and be inserted into the pin groove 608 on the outer surface of the docking rod 602, thereby completing the locking of the docking rod 602, improving the stability of the connection between the grinding cylinder 2 and the base 1, and ensuring that the grinding cylinder 2 is in a stable state during the grinding process.

[0044] According to the technical solution provided by the present invention, when grinding tablets, the top cover 401 is opened to put the tablets into the grinding cylinder 2, and then the grinding cylinder 2 is installed on the base 1. Specifically, the docking rod 602 is aligned with the docking hole 601 and inserted, and the grinding cylinder 2 is pressed to make its bottom fit with the upper surface of the base 1, so that the docking rod 602 will push the pressure rod 701, forcing the pressure rod 701 to squeeze the suction cup 702 and the spring 2 703. The suction cup 702 is adsorbed on the desktop by the pressure of the pressure rod 701, thereby improving the stability of the base 1, and then the gear ring 603 is rotated. During the rotation of the gear ring 603, the gear 2 604 is driven to rotate, which in turn drives the shift block 605 to rotate around the gear. The center of the second wheel 604 makes a circular motion. Since the shifting block 605 slides in the hollow plate 606, the hollow plate 606 is driven to make a linear motion, so that the pin rod 607 is driven to move and insert into the pin groove 608 on the outer surface of the docking rod 602, so as to complete the locking of the docking rod 602, thereby improving the stability of the connection between the grinding cylinder 2 and the base 1, ensuring that the grinding cylinder 2 is in a stable state during the grinding process, and starting the motor 301. The motor 301 drives the transmission rod 302 to rotate and drives the cylinder 303 to rotate. The extension rods 304 distributed around the cylinder 303 will rotate with the cylinder 303 and drive the grinding sheet 305 to grind the tablets, thereby achieving the purpose of grinding the tablets into powder;

[0045] After the tablet is ground, the push rod 402 is pressed downward, and the spring 404 is stretched, and the card plate 403 is pushed to be connected to the top of the vertical rod 307. Then, the push rod 402 is rotated to drive the vertical rod 307 to rotate, and the driven wheel 308 drives the surrounding driven wheel 309 to rotate synchronously, thereby driving the extension rod 304 to rotate, so that the grinding sheet 305 rotates to the upper part, and the upper cleaning brush 306 rotates to the lower part. The push rod 402 is released, and the card plate 403 is pulled up and separated from the vertical rod 307 under the elastic force of the spring 404, so that the grinding sheet 305 and the cleaning brush 306 are switched. Then the push block 508 is pushed, and the push block 508 drives the rack 506 to move, and the gear meshes with the gear 507, and then the rack During the movement of 506, gear 507 will be driven to rotate, and the shaft will rotate with gear 507 and drive the sealing plate 504 to rotate, so that the sealing plate 504 is switched from a horizontal state to a vertical state, and the opening 502 is also opened. At this time, when the motor 301 drives the transmission rod 302 to rotate, the cleaning brush 306 will rotate around the cylinder 303, and then the powder in the grinding cylinder 2 will be cleaned, and the powder will be cleaned to the position of the opening 502 and collected in the collecting box 501. In the operation of the cleaning brush 306, it will contact the tooth block 505, and the tooth block 505 can shake off the powder adhered to the cleaning brush 306, thereby ensuring the integrity of the powder amount. At the same time, it also realizes the effect of automatically collecting the powder without manual collection, thereby improving the practicality of the device.
