The drain pipe is inserted into the second water hole, a liquid discharge pipe 16 is formed in the bottom of the barrel body 1, and a valve is arranged on the liquid discharge pipe 16.

[0031] When the present utility model is in specific use, first, water needs to be added to the barrel body 1. In order to prevent the water in the barrel from overflowing during boiling, a water level line is provided in the barrel body 1. Through the water level line, the amount of water in the barrel can be known, which is convenient for the ratio of traditional Chinese medicine liquid to Western medicine tablets, and it can also be checked whether the water in the barrel body 1 exceeds the water level line. When preparing the mixed liquid medicine, after filtering the residue of the traditional Chinese medicine materials, the powder of Western medicine tablets needs to be added and mixed. Therefore, the filter cage 18 needs to be lifted so that the height of the lower end surface of the filter cage 18 is higher than the liquid level of the barrel body 1. Therefore, the upper limit of the water level line is set according to the height of the lower end surface of the filter cage 18 after it is lifted. After adding a certain amount of water to the barrel body 1, the traditional Chinese medicine materials to be boiled are put into the filter cage 18, the filter cage 18 is connected to the barrel cover 14 through a connection structure, and then the filter cage 18 is placed in the barrel body 1, and the connection structure is adjusted so that the filter cage 18 is immersed in the water in the barrel body 1. The constant temperature heating structure installed in the base of the present utility model is prior art and will not be described in detail here. Further, a heat insulation layer is provided outside the first motor to reduce the influence of the constant temperature heating structure on the first motor during heating. Further, the filter cage 18 mainly includes a cage body and a cage cover. The cage cover is installed on the cage body. Filter holes are provided on the cage body. A connection ring is installed on the upper end surface of the cage cover, and the connection structure is connected to the connection ring. Open the cage cover, put the traditional Chinese medicine materials into the cage body, and then fix the cage cover and the cage body so that the internal traditional Chinese medicine materials will not fall out. The cage cover and the cage body can be connected by threads or fixed by a buckle structure. The fixing method of the cage cover and the cage body is not limited as long as they can be stably connected together. The water in the barrel body 1 can enter and exit the filter cage 18 through the filter holes, so that placing the traditional Chinese medicine materials in the filter cage 18 does not affect the boiling of traditional Chinese medicine. When the boiling of the traditional Chinese medicine liquid is completed, the filter cage 18 is lifted by using the connection structure for filtering. Further, the connection structure mainly includes an electric push rod 13. The electric push rod 13 is installed on the upper end surface of the barrel cover 14. The push rod of the electric push rod 13 is vertically downward. A rod hole is provided on the barrel cover 14. The push rod extends into the barrel body 1 through the rod hole. A hook is provided at the lower end of the push rod. The connection ring is installed at the central position of the cage cover, and the connection ring is hung on the hook. By pushing the push rod of the electric push rod 13 downward, the filter cage 18 hung on the hook can be immersed in the water in the barrel body 1, which is convenient for boiling the traditional Chinese medicine materials. When the boiling is completed, the push rod of the electric push rod 13 is retracted upward, so that the filter cage 18 on the hook of the push rod moves upward together, so that the filter cage 18 is separated from the liquid in the barrel body 1, and the water in the filter cage 18 continuously flows into the barrel body 1 through the filter holes on the cage body, completing the filtration of the traditional Chinese medicine residue. In this process, it is not necessary to open the barrel cover 14, nor to lift the filter cage 18 by hand, reducing the possibility of medical staff being scalded by the liquid medicine and being more time-saving and labor-saving. While the connection structure lifts the filter cage 18 for filtering, the next operation of mixing the liquid medicine can be carried out, saving time. Because the texture of Western medicine tablets is relatively hard and not easy to dissolve.In order to enable the western medicine tablets to dissolve quickly in the traditional Chinese medicine liquid and obtain a liquid medicine with evenly mixed medicinal effects, it is necessary to grind the western medicine tablets. The grinding cylinder of the present utility model is installed on the outer side wall of the barrel body 1 through a fixing structure, which is convenient for use. While decocting the traditional Chinese medicine, the grinding cylinder can be used to grind the western medicine tablets placed in the cylinder body. Put the western medicine tablets into the cylinder body, start the second motor 11, so that the grinding head 24 connected to the second rotating shaft 19 rotates, and the grinding head 24 and the grinding disc at the bottom of the cylinder body grind the western medicine tablets into powder. In order to facilitate the mixing of the powder ground in the grinding cylinder with the traditional Chinese medicine liquid in the barrel body 1. Further, a water pump 10 is provided on the cylinder cover 8. After lifting the filter cage 18 using the connection structure first and grinding the western medicine tablets in the grinding cylinder into powder, start the water pump 10, suck the filtered traditional Chinese medicine liquid in the barrel body 1 from the first water hole of the barrel body 1 into the cylinder body of the grinding cylinder. After the traditional Chinese medicine liquid enters the cylinder body, the western medicine powder in the cylinder body dissolves in the traditional Chinese medicine liquid, and then the traditional Chinese medicine liquid with western medicine powder is discharged into the barrel body 1 of the decocting barrel through the drain pipe at the bottom of the cylinder body. According to the actual situation, the working time of the second motor 11 and the water pump can be controlled. As the water pump 10 continuously pumps, the traditional Chinese medicine liquid flushes all the western medicine powder in the cylinder body into the barrel body 1 of the decocting barrel, reducing the residue amount of the powder in the cylinder body. Further, when the water pump 10 is working, the second motor 11 can work simultaneously, and the western medicine tablets can be ground more finely and are more easily soluble. When the western medicine powder in the grinding cylinder enters the barrel body 1, start the first motor, and use the stirring blade 17 to mix the liquid medicine in the barrel body 1, so that the western medicine powder can dissolve faster and more evenly. When the mixed liquid medicine is discharged into the packaging bag through the drain pipe 16 of the barrel body 1, the stirring blade 17 can continue to work, so that the mixed liquid medicine in the barrel body 1 will not be static and is not easy to precipitate, making the medicinal effect of the mixed liquid medicine more uniform and beneficial to treating patients.

[0032] Further, two symmetrically arranged bracelets 15 are installed on the outer side wall of the barrel body 1, which is convenient for moving the decocting barrel.

[0033] Further, the fixing structure includes a left fixing band 4 and a right fixing band 2. Fixing ears 3 are installed at both ends of the left fixing band 4 and the right fixing band 2. Fixing holes are formed in each fixing ear 3. A fixing screw is passed through the fixing holes of the left fixing band 4 and the right fixing band 2, and a fixing nut is threadedly connected to the fixing screw. The head end of the fixing screw and the fixing nut respectively abut against the outer sides of the two fixing ears 3, and the left fixing band 4 and the right fixing band 2 are connected into an annular fixing ring; a fixing cylinder 6 is installed on the outer side of the fixing ring. The barrel of the grinding cylinder is placed in the fixing cylinder 6. A cylinder hole is formed in the side wall of the fixing cylinder 6, and a fastening stud 5 is threadedly connected in the cylinder hole. The end of the fastening stud 5 abuts against the outer side wall of the grinding cylinder. The fixing structure detachably connects the grinding cylinder and the decocting cylinder, facilitating the separate use of the decocting barrel and the grinding cylinder after disassembly. The fixing structure can also be disassembled, reducing the occupied space position. The fixing structure clamps the left fixing band 4 and the right fixing band 2 outside the barrel body 1 through the fixing screw and the fixing nut. By disassembling the fixing screw and the fixing nut, the fixing structure can be removed. When using the grinding cylinder to grind Western medicine tablets, when the second motor 11 is started, the grinding cylinder will shake. Therefore, it is necessary to fix the grinding cylinder so that the grinding can proceed normally. It is necessary to place the barrel of the grinding cylinder in the fixing cylinder 6, and then rotate the fastening stud 5 so that the end of the fastening stud 5 abuts against the outer side wall of the barrel, making the barrel fit with the inner side wall of the fixing cylinder 6, thereby fixing the barrel in the fixing cylinder 6. When grinding, the barrel is fixed and the grinding can proceed normally.

[0034] When there are relatively many Western medicine tablets to be ground, the powder will accumulate on the grinding plate at the bottom of the barrel, affecting the continuous grinding of other unground Western medicine tablets. Further, the barrel is divided into an upper barrel 7 and a lower barrel 25. The lower end of the upper barrel 7 is threadedly connected to the upper end of the lower barrel 25. The grinding plate at the bottom of the upper barrel 7 has an arc-shaped structure, and the arc of the grinding plate opens upward. The lower end surface of the grinding head 24 has an arc-shaped structure. The grinding plate is provided with a plurality of sieve holes. A receiving cavity is formed between the lower barrel 25 and the upper barrel 7. A drain pipe is installed at the lower end of the lower barrel 25. The Western medicine ground into powder will fall into the receiving cavity through the sieve holes, so that the Western medicine tablets to be ground are placed on the grinding plate, facilitating grinding. Moreover, the upper barrel 7 and the lower barrel 25 can be separated, facilitating cleaning after disassembly and avoiding the influence of residual medicine on the medicine to be ground subsequently.

[0035] Further, a plurality of convex points are provided on the inner surface of the grinding plate and the lower end surface of the grinding head 24, increasing the roughness of the contact surface and the friction force, making the grinding of Western medicine tablets more delicate.

[0036] Because as the Western medicine tablets are ground, the large tablets become small particles or partially turn into powder. As the size of the tablets becomes smaller, but the distance between the grinding head 24 and the grinding disc is fixed, some small tablet particles are smaller than the distance, so they are not easily ground. Or when grinding tablets of different sizes, the distance between the grinding head 24 and the grinding disc is also different. Therefore, further, a sliding hole is provided at the lower end of the second rotating shaft 19. The length direction of the sliding hole is parallel to the length direction of the second rotating shaft 19. The sliding hole is a non-circular hole. The connecting rod is divided into two parts, an upper rod 26 and a lower rod 23. The upper rod 26 is slidably connected in the sliding hole. A retaining cylinder is detachably connected to the lower end of the second rotating shaft 19. A limiting hole is provided at the end of the retaining cylinder. The size of the limiting hole is smaller than the cross-sectional size of the upper rod 26, and the size of the limiting hole is larger than the cross-sectional size of the lower rod 23. An upper limiting nut 20 is threadedly connected to the second rotating shaft 19, and a lower limiting nut 22 is threadedly connected to the lower rod 23. A spring 21 is installed between the upper limiting nut 20 and the lower limiting nut 22. The upper end of the spring 21 abuts against the lower end surface of the upper limiting nut 20, and the lower end of the spring 21 abuts against the upper end surface of the lower limiting nut 22. The upper end surface of the lower limiting nut 22 abuts against the lower end surface of the retaining cylinder. Because the sliding hole in the second rotating shaft 19 is a non-circular hole, when the second rotating shaft 19 rotates, the upper rod 26 slidably connected in the sliding hole will not rotate. Therefore, the upper rod 26 will rotate together with the second rotating shaft 19. The upper rod 26 and the lower rod 23 are an integral rod. Therefore, the lower rod 23 and the grinding head 24 connected to the lower end of the lower rod 23 rotate together. Also because the upper rod 26 slides in the second rotating shaft 19 and the size of the limiting hole of the retaining cylinder is smaller than that of the upper rod 26, therefore, under the blocking action of the retaining cylinder, the upper rod 26 will not slip out of the sliding hole; and because the size of the lower rod 23 is smaller than the size of the limiting hole, the lower rod 23 can enter the sliding hole of the second rotating shaft 19. However, the size of the lower limiting nut 22 threadedly connected to the lower rod 23 is larger than the size of the retaining cylinder. Therefore, the lower limiting nut 22 can block the lower rod 23 from entering the sliding hole. Therefore, the depth of the lower rod 23 entering the sliding hole can be adjusted by adjusting the position of the lower limiting nut 22 on the lower rod 23. The distance between the lower end surface of the lower limiting nut 22 and the grinding disc can be adjusted according to the size of the tablets. At the beginning of grinding, the upper end surface of the lower limiting nut 22 abuts against the lower end surface of the retaining cylinder, so that the grinding head 24 presses on the Western medicine tablets. Then, the position of the upper limiting nut 20 is adjusted so that the spring 21 between the upper limiting nut 20 and the lower limiting nut 22 is always in a compressed state. As the grinding continues, the large particle tablets become small particle tablets or powder, and the compressed spring 21 makes the grinding head 24 always press on the tablets to be ground, making the grinding more delicate. Further, a buffer pad is provided on the lower end surface of the retaining cylinder. When the grinding head 24 grinds, the lower limiting nut 22 is likely to hit the retaining cylinder, and the buffer pad plays a buffering role.

[0037] Specific Embodiment 2, on the basis of Specific Embodiment 1, only the connection structure is changed. The connection structure mainly includes two connecting ropes. Two rope holes are provided on the bucket lid 14. Each connecting rope is threaded through one rope hole. Two connecting rings are provided on the cage lid. The positions of the two connecting rings are symmetrical. One end of each connecting rope is connected to one connecting ring. The other end of each connecting rope is connected with a clamping rod. The clamping rod is located outside the bucket lid 14. When decocting traditional Chinese medicine, the clamping rod is clamped on the upper end surface of the bucket lid 14, so that the filter cage 18 is immersed in the bucket body 1. Further, the length of the connecting rope can be adjusted, so that the filter cage 18 can be immersed in the water in the bucket body 1. The way to adjust the length is the prior art and will not be described in detail here. When filtering is needed, the two connecting ropes are pulled by the clamping rod, so that the filter cage 18 connected by the connecting ropes is lifted and separated from the liquid in the bucket. The way for the filter cage 18 to be separated from the liquid level can be to adjust the length of the connecting rope, or the clamping rods can be respectively clamped in the bracelet rings 15 on both sides of the bucket body 1, so that the position of the filter cage 18 is fixed and will not fall. The filtration is completed without opening the bucket lid 14 and without contacting the medicinal liquid, reducing the risk of scalding for medical staff. And the manufacturing cost is low.

[0038] The above description is a detailed description of the preferred and feasible embodiments of the present invention, but the embodiments are not intended to limit the patent application scope of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the patent scope covered by the present invention.
