Description

Technical Field

[0001] The invention relates to the technical field of drug grinding, in particular to a drug grinding device for pediatric medical use. Background Art

[0002] In pediatrics, Chinese medicine believes that children are full of vitality but immature, and their internal organs are not yet fully functioning. Therefore, they are sensitive to external changes and are easily affected by external pathogens. Chinese medicine can achieve the purpose of treating diseases by harmonizing yin and yang, balancing qi and blood, and adjusting the internal environment of children. Moreover, compared with some Western medicines, the side effects of Chinese medicine are generally considered to be smaller, especially for children, a special population. The toxic side effects of Chinese medicine are relatively low, and it is more suitable for the treatment of pediatric diseases.

[0003] In actual situations, since the internal organs of children are not yet fully functional, it is necessary to precisely control the dosage of the medicine. While controlling the dosage, it is also necessary to ensure the absorption of the medicine. Therefore, it is necessary to grind the Chinese medicine and increase the surface area of ​​the Chinese medicine particles to help increase the contact area between the active ingredients of the medicine and the solvent, and speed up the dissolution rate of the active ingredients, thereby ensuring the therapeutic effect on children. In addition, some Chinese medicines are highly irritating, and crushing can reduce this irritation, making the medicine milder.

[0004] Many of the current Chinese medicine crushing devices are manually chopped. At home, parents usually use small grinders (such as soy milk machines) to crush Chinese medicines. However, since Chinese medicines are usually dried in the sun, the hardness of Chinese medicines (dry stems of plants) will become drier and harder after drying. Especially for larger Chinese medicines, the grinder needs more time to crush them, which reduces the crushing efficiency. However, the longer the stirring time, the longer the friction time between the blade and the Chinese medicine, and the higher the temperature, which may affect the efficacy of the medicine. In addition, it will affect the crushing effect and even cause wear or even damage to the cutting edge of the crushing blade. Summary of the invention

DETAILED DESCRIPTION

[0028] Reference Figure 1-Figure 11 The present invention provides a drug grinding device for pediatric medical treatment, comprising a crushing cylinder 1 and a bracket 2, wherein the crushing cylinder 1 is rotatably mounted on the bracket 2, a crushing chamber is provided on the crushing cylinder 1, a blade 3 is rotatably mounted in the crushing chamber of the crushing cylinder 1, the blade 3 has four blades, one side of the blade of the blade 3 is a crushing edge, the crushing edge can crush Chinese medicine, the other side of the blade of the blade 3 is teeth, the teeth can crush large pieces of Chinese medicine first, and then the crushed Chinese medicine is crushed by the crushing edge, the bottom surface of the blade 3 is arranged obliquely with the bottom surface of the crushing chamber, the blade 3 can be raised and lowered in the crushing chamber, in actual conditions, the blade 3 can rotate in both directions in the crushing chamber, when the blade 3 rotates forward in the crushing chamber, the blade 3 drops to a low position in the crushing chamber, and the end of the gear cooling column 4 is arranged flush with the bottom inner wall of the crushing chamber, the blade 3 can crush the Chinese medicine.

[0029] In addition, in actual situations, during the crushing operation, a large amount of heat will be generated due to the friction between the blade 3 and the Chinese medicinal materials. The efficacy of some Chinese medicinal materials will be weakened under the influence of high temperature. For example, mint, cinnamon, tangerine peel, etc., the volatile oil components in these medicinal materials are easy to volatilize at high temperatures, resulting in loss of efficacy; papaya, pineapple, etc., they contain enzyme components, high temperature may cause enzyme inactivation, affecting their efficacy; such as wolfberry, red dates, etc., high temperature may cause sugar decomposition, affecting their efficacy; Coptis chinensis, Bupleurum, etc., glycoside components may be hydrolyzed at high temperatures, resulting in loss of efficacy, etc., so they need to be cooled.

[0030] like Figure 2 , Figure 4 and Figure 5As shown in, a mounting hole is provided on the bottom inner wall of the crushing chamber, and a gear cooling column 4 is slidably installed in the mounting hole. The gear cooling column 4 is preferably cylindrical, and the diameter of the gear cooling column 4 is the same as the inner diameter of the mounting hole. A cooling chamber 7 is provided in the crushing barrel 1, and the cooling chamber 7 is filled with coolant. The other end of the gear cooling column 4 extends into the cooling chamber 7. The gear cooling column 4 can cool the Chinese medicinal materials in the crushing chamber, thereby reducing the influence of high temperature on the Chinese medicinal materials during the crushing process. When the blade 3 rotates in the opposite direction in the crushing chamber, the blade 3 rises to a high position in the crushing chamber, and one end of the gear cooling column 4 extends into the crushing chamber. The blade 3 and the gear cooling column 4 can perform a crushing operation. In specific use, the Chinese medicinal materials are placed in the crushing chamber, and the blade 3 is driven to rotate in the opposite direction first. When the blade 3 rotates in the opposite direction, the blade 3 will rise in the crushing chamber, so that the gap between the blade 3 and the bottom inner wall of the crushing chamber becomes larger, and at the same time, the end of the gear cooling column 4 extends from the mounting hole, and the Chinese medicinal materials will reach the blade 3 and the crushing chamber In the gap between the inner walls of the bottom, the Chinese medicinal materials are stuck in the gap between the multiple gear cooling columns 4, and then the blade 3 rotates in the opposite direction. The teeth on the back of the blade 3 will scrape the Chinese medicinal materials, so that the Chinese medicinal materials are crushed in the gap between the blade 3 and the gear cooling column 4, so that large pieces of Chinese medicinal materials are broken into small pieces of Chinese medicinal materials. After the Chinese medicinal materials are broken into small pieces, when crushing the Chinese medicinal materials, it is necessary to rotate the entire crushing cylinder 1 so that the Chinese medicinal materials in the crushing cylinder 1 are crushed. The blade 3 is driven to rotate forwardly. When the blade 3 rotates forwardly, the blade 3 descends in the crushing chamber, so that the blade 3 can reach the height of crushing small pieces of Chinese medicinal materials, thereby crushing small pieces of Chinese medicinal materials, which can reduce the wear of the cutting edge of the blade 3 by the Chinese medicinal materials. During rolling and crushing, the gear cooling column 4 has a certain cooling effect on the Chinese medicinal materials in the crushing chamber, which can reduce the weakening of the medicinal effect of the medicinal materials due to high temperature during the crushing process.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown in the figure, a moving chamber is opened in the crushing barrel 1, a moving block 5 is slidably installed in the moving chamber, a motor 6 is fixedly installed in the moving block 5, and the output shaft of the motor 6 passes through the moving block 5 and extends into the crushing chamber and is detachably connected to the blade 3; a cooling chamber 7 is opened in the moving block 5, and a gear cooling column 4 is fixedly installed on the moving block 5. When in use, the motor 6 drives the blade 3 to rotate forward and reverse in the crushing chamber, the moving block 5 can only slide in the moving chamber, and the moving block 5 cannot rotate in the moving chamber. At the same time, the coolant in the cooling chamber 7 absorbs the temperature on the gear cooling column 4, and the gear cooling column 4 absorbs the heat generated by the Chinese medicinal materials during the crushing process, thereby cooling the Chinese medicinal materials to ensure the efficacy of the Chinese medicinal materials.

[0032] like Figure 2, Figure 4 , Figure 5 and Figure 6 As shown in the figure, a sliding shaft 8 is fixedly connected to the output shaft of the motor 6, a guide groove is provided in the crushing barrel 1, and the sliding shaft 8 slides in the guide groove, and the guide groove includes a No. 1 annular groove 9, a No. 2 annular groove 10 and a connecting inclined groove 11; the No. 1 annular groove 9 and the No. 2 annular groove 10 are provided in the crushing barrel 1, and there is a gap between the No. 1 annular groove 9 and the No. 2 annular groove 10, and the two ends of the connecting inclined groove 11 are respectively connected with the No. 1 annular groove 9 and the No. 2 annular groove 10, and the connecting inclined groove 11 is arranged obliquely, and the connecting portion of the No. 1 annular groove 9 and the connecting inclined groove 11 is rotatably installed. The first shift plate 12 is rotatably mounted at the connection between the first annular groove 9 and the connected inclined groove 11 through a rotating shaft, and a first torsion spring is mounted on the rotating shaft of the first shift plate 12. The second shift plate 13 is rotatably mounted at the connection between the second annular groove 10 and the connected inclined groove 11 through a rotating shaft, and a second torsion spring is mounted on the rotating shaft of the second shift plate 13. The first torsion spring and the second torsion spring drive the first shift plate 12 and the second shift plate 13 respectively. Figure 6 As shown in , when the output shaft of the motor 6 rotates forward, the sliding shaft 8 will slide down along the connecting inclined groove 11, so that the sliding shaft 8 slides from the No. 1 annular groove 9 to the No. 2 annular groove 10, and when the sliding shaft 8 encounters the No. 2 shift plate 13 in the No. 2 annular groove 10, the sliding shaft 8 will drive the No. 2 shift plate 13 to rotate and slide in the No. 2 annular groove 10. When the sliding shaft 8 pushes away the No. 2 shift plate 13 to rotate, the No. 2 shift plate 13 will block the sliding shaft 8 from entering the connecting inclined groove 11. When the motor 6 drives the blade 3 to rotate in the opposite direction, the working principle is similar to the above, so that the sliding shaft 8 slides in the No. 1 annular groove 9, thereby ensuring the crushing and pulverizing of the Chinese medicinal materials.

[0033] like Figure 2 , Figure 5 , Figure 7 and Fig.10 As shown in , a telescopic groove is provided on the bottom surface of the blade 3, and a protrusion 14 is slidably installed in the telescopic groove. When the blade 3 performs a crushing operation, the bottom end of the protrusion 14 is flush with the bottom surface of the blade 3, and the protrusion 14 blocks the telescopic groove; a driving structure is installed on the blade 3, and the driving structure can drive the protrusion 14 to extend out of the telescopic groove. When crushing large pieces of Chinese medicinal materials, the protrusion 14 is extended out of the telescopic groove, so that the protrusion 14 protrudes from the bottom surface of the blade 3. When crushing large pieces of Chinese medicinal materials, the large pieces of Chinese medicinal materials are crushed by the protruding protrusion 14, the bottom surface of the blade 3 and the gear cooling column 4, increasing the friction of the bottom surface of the blade 3, thereby increasing the crushing effect (during the crushing operation, the protrusion 14 is retracted into the telescopic groove, so that the bottom surface of the blade 3 is on a smooth surface, reducing the possibility of powder stuck in the corners).

[0034] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig.10 The driving structure shown in the figure includes a lifting block 15, a pushing block 16, a triangular block 17 and a driving component; there are multiple protrusions 14, and a lifting groove that slides with the lifting block 15 is provided in the blade 3. Multiple protrusions 14 are fixedly connected to a lifting block 15, and the pushing block 16 is slidably installed in the lifting groove. The triangular block 17 is fixedly installed on the side of the pushing block 16 close to the lifting block 15, and the side of the lifting block 15 away from the protrusion 14 is provided with an inclined groove 18, and the inclined surface of the triangular block 17 slides with the inner wall of the inclined groove 18; a reset groove is provided on the bottom inner wall of the lifting groove, and a retraction spring 19 is installed in the reset groove. The two ends of the retraction spring 19 are respectively fixedly connected to the bottom inner wall of the reset groove and the lifting block 15, and the retraction spring 19 can push the lifting block 15 and the protrusion 14 to lift. When the protrusion 14 is driven to extend out of the telescopic groove, the pushing block 16 moves horizontally in the lifting groove, and the pushing block 16 drives multiple triangular blocks 17 to move horizontally synchronously. When the triangular block 17 moves horizontally, the inclined surface of the triangular block 17 and the inner wall inclined surface of the inclined surface groove 18 slide and cooperate to drive the lifting block 15 down in the lifting groove, and the lifting block 15 drives multiple protrusions 14 to protrude out of the telescopic groove. During the crushing process, the protrusion 14 is subjected to the reaction force of the Chinese medicinal materials, so that the protrusion 14 has the effect of rising in the telescopic groove, but because the triangular block 17 is supported on the protrusion 14, the protruding effect of the protrusion 14 is ensured, and the protrusion 14 is reduced to be retracted by the reaction force of the Chinese medicinal materials.

[0035] like Figure 2 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.11As shown in, the driving assembly includes a tetrahedral block 20, a trapezoidal block 21, a pushing rod 22, a driving rod 23 and a lifting spring 24; a movable groove is opened in the motor 6, and the tetrahedral block 20 is slidably installed in the movable groove. The number of trapezoidal blocks 21 is multiple, and the multiple trapezoidal blocks 21 are the same as the number of blades of the blade 3 and are arranged one by one. The multiple trapezoidal blocks 21 are all slidably installed in the movable groove, and the inclined surface of the trapezoidal block 21 is slidably matched with the inclined surface of the tetrahedral block 20. One end of the pushing rod 22 is fixedly connected to the side of the trapezoidal block 21 away from the tetrahedral block 20. The number of pushing rods 22 is the same as the number of trapezoidal blocks 21 and is arranged one by one. The end of the pushing rod 22 away from the trapezoidal block 21 can be inserted into the movable groove and push the pushing block 16 to slide in the lifting groove. One end of the driving rod 23 is fixedly connected to the tetrahedral block 20, and the end of the driving rod 23 away from the tetrahedral block 20 slides through the end of the output shaft of the motor 6. And it extends to the outside of the end of the output shaft of the motor 6. The lifting spring 24 is installed in the movable groove. The two ends of the lifting spring 24 are respectively fixedly connected with one end of the four-sided pyramid block 20 away from the driving rod 23 and the bottom inner wall of the movable groove. During operation, by pressing the driving rod 23, the driving rod 23 is retracted at the end of the output shaft of the motor 6, and the driving rod 23 pushes the four-sided pyramid block 20 to descend in the movable groove, so that the inclined surface of the four-sided pyramid block 20 and the inclined surface of the trapezoidal block 21 slide and cooperate, the trapezoidal block 21 moves laterally in the movable groove, the trapezoidal block 21 pushes the pushing rod 22 to slide laterally, the pushing rod 22 moves laterally and extends out of the outside of the output shaft of the motor 6, the end of the pushing rod 22 enters the lifting groove of the blade 3, the end of the pushing rod 22 extends into the lifting groove, and the end of the pushing rod 22 abuts against the end of the pushing block 16, thereby pushing the pushing block 16 to slide laterally in the lifting groove, thereby completing the driving protrusion 14 to extend out of the telescopic groove.

[0036] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown in the figure, the outer periphery of the output shaft of the motor 6 is fixedly connected to the limit block 29, and the blade 3 is mounted on the output shaft of the motor 6. The limit block 29 plays a limiting role and ensures that the push rod 22 can push the push block 16 to move horizontally in the lifting groove.

[0037] like Figure 1 , Figure 2 and Figure 5As shown in the figure, a cylinder cover 25 is detachably mounted on the crushing cylinder 1, and the cylinder cover 25 can block the opening of the crushing chamber. A straight rod 26 is fixedly connected to the cylinder cover 25, and the end of the straight rod 26 can abut against the end of the driving rod 23. A sliding sleeve 27 is slidably mounted on the straight rod 26, and the end of the sliding sleeve 27 can abut against the end of the output shaft of the motor 6. A reset spring 28 is mounted on the straight rod 26, and the two ends of the reset spring 28 are respectively connected to the ends of the cylinder cover 25 and the sliding sleeve 27. When crushing Chinese medicinal materials, the Chinese medicinal materials are placed in the crushing chamber, and then the cylinder is The cover 25 is closed so that the end of the straight rod 26 abuts against the driving rod 23, and the end of the sleeve 27 abuts against the end of the output shaft of the motor 6. When the crushing operation is performed, the end of the output shaft of the motor 6 also rises, and the end of the output shaft of the motor 6 drives the sleeve 27 to rise synchronously. Since the driving rod 23 cannot rise due to the abutment of the straight rod 26, the driving protrusion 14 protrudes in the telescopic groove. It should be noted that the protrusion 14 and the gear cooling column 4 are in a misaligned state. When the blade 3 rotates, the protrusion 14 and the gear cooling column 4 will not collide with each other.
