[0033] The crankshaft 9 and the output shaft 8 are integrally arranged, and the crankshaft 9 and the inside of the Lelo triangular rotor 5, and the output shaft 8 and the fixed gear 7 are movably arranged. The tooth ratio of the fixed gear 7 to the inner ring gear 6 is 2:3. By driving the output shaft 8 to drive the crankshaft 9 to rotate, the eccentric rotation of the Lelo triangular rotor 5 in the grinding cylinder 4 is realized, thereby achieving the grinding, crushing and dissolution of the medicine in the grinding cylinder 4.

[0034] The three vertices of the Lelo triangular rotor 5 are all provided with sealing strips which are in contact with the inner wall of the grinding cylinder 4. The sealing strips can ensure that the three vertices of the Lelo triangular rotor 5 are always in contact with the grinding cylinder 4 and are sealed.

[0035] The exhaust port 11 is provided with an air pressure opening and closing valve 12 at the grinding cylinder 4. The air pressure opening and closing valve 12 can release the pressure when the pressure inside the grinding cylinder 4 is too high. The dissolving liquid is introduced into the liquid inlet 10, and the solid medicine to be dissolved is placed in the medicine inlet 14.

[0036] The mixing assembly includes a mixing tube 15, a pressure pump 16 and a tube clamp seat 17. The tube clamp seat 17 is rotatably installed inside the housing 1. The tube clamp seat 17 is a prototype as a whole. A reciprocating swing motor is connected to the rear end of the tube clamp seat 17. Two groups of clamp arms 18 are provided at the front end of the tube clamp seat 17. The mixing tube 15 is clamped between the two groups of clamp arms 18. An inlet is provided at the top of the mixing tube 15. The inlet at the top of the mixing tube 15 is connected to the liquid outlet 13 through a hose 19. An air inlet 20 is provided on one side of the upper part of the mixing tube 15. The air inlet 20 at the upper part of the mixing tube 15 The mixing tube 15 is connected with the pressure pump 16 through a hose 19, and the pressure pump 16 is installed in the shell 1.

A first outlet of the first three-way valve 25 is connected to an inlet at the top of the mixing tube 15 through a hose 19. A waste liquid channel 26 is also provided at the second outlet of the first three-way valve 25 and passes through the outside of the shell 1. The flow direction of the solution or waste liquid for dissolving the drug is controlled by the first three-way valve 25.

[0040] The filter assembly includes an upper movable clamp seat 27, a lower fixed clamp seat 28 and a filter element 29. The lower fixed clamp seat 28 is fixedly installed in the housing 1. The upper movable clamp seat 27 is arranged above the lower fixed clamp seat 28. One side of the upper movable clamp seat 27 is connected to the outlet hose 19 at the lower part of the mixing tube 15. Four groups of guide columns 30 are arranged around the upper movable clamp seat 27. A mounting plate 31 is arranged on the top of the four groups of guide columns 30. A micro cylinder 32 is arranged above the mounting plate 31. The output end of the micro cylinder 32 passes through the mounting plate 31 and is connected to the upper part of the upper movable clamp seat 27. The filter element 29 is connected to the upper part of the upper movable clamp seat 27 through the movable plate 31. The movable plate 33 is installed between the upper movable clamp seat 27 and the lower fixed clamp seat 28. A circular opening 34 is provided in the middle of the movable plate 33. The circular opening 34 is provided with a placement step 35 around it. A second three-way valve 36 is connected to the lower part of the lower fixed clamp seat 28. The inlet of the second three-way valve 36 is communicated with the lower part of the lower fixed clamp seat 28. The first outlet of the second three-way valve 36 is communicated with the waste liquid channel 26. The second outlet of the second three-way valve 36 extends downward to the outside of the housing 1. The filter element 29 can be sealed and clamped up and down by the micro cylinder 32, so as to achieve sealed communication with the filter element 29.

[0041] Two groups of threaded rods 37 are arranged through the transmission on both sides of the movable plate 33. Both ends of the threaded rods 37 are arranged on the shell 1 through mounting seats 38. One group of mounting seats 38 is arranged close to the guide column 30, and two groups of adjustment motors 39 are installed thereon, which are respectively connected to the two groups of threaded rods 37 in transmission. The other group of mounting seats 38 is arranged through the outside of the shell 1. The filter element 29 can be quickly replaced through the transmission of the movable plate 33 on the threaded rod 37.

[0042] The working process of the present invention is as follows: firstly, the medicine to be crushed and dissolved is placed in the medicine inlet 14, and the liquid inlet 10 is connected to the external dissolving liquid, and the output motor drives the crankshaft 9 on the output shaft 8 to realize the eccentric rotation of the Lelo triangle rotor 5, and waits until the medicine to be crushed and dissolved is placed in the medicine inlet 14, and the liquid inlet 10 is connected to the external dissolving liquid, and the output motor drives the crankshaft 9 on the output shaft 8 to realize the eccentric rotation of the Lelo triangle rotor 5. Figure 5 When the drug inlet 14 is in the state, the drug inlet 14 can achieve the entry of the drug due to the eccentric rotation of the Lelo triangular rotor 5. Figure 6As shown, since the cavity between the side wall of the Lelo triangular rotor 5 and the grinding cylinder 4 is getting larger and larger, the medicine can completely enter the grinding cylinder 4, as shown in FIG. Figure 7 As shown in the figure, after the vertex of the Lelo triangular rotor 5 passes the medicine inlet 14, the cavity between the side wall of the Lelo triangular rotor 5 and the grinding cylinder 4 becomes smaller and smaller. Figure 8 As shown, the side wall of the Lelo triangular rotor 5 is in close contact with the inner wall of the grinding cylinder 4, so that the medicine can be fully crushed. If the internal air pressure is too high, the air pressure can be released through the air pressure opening and closing valve 12. At this time, the cavity between the side wall of the Lelo triangular rotor 5 and the inner wall of the grinding cylinder 4 becomes larger again due to the eccentric rotation. At the same time, the liquid inlet 10 introduces the dissolved liquid due to the internal pressure or external pumping. Fig. 9 As shown, the crushed medicine is initially dissolved, and when the cavity between the side wall of the subsequent Lelo triangular rotor 5 and the crushing cylinder 4 becomes smaller, as shown in FIG. Fig.10 As shown, finally, the initially dissolved solution is completely pressed into the mixing tube 15 from the liquid outlet 13, and the final crushing and dissolution of the drug is achieved through the two sets of cavity circulation. At this time, the electromagnetic clamping valve 21 at the bottom of the mixing tube 15 squeezes and closes the hose 19. After the solution in the mixing tube 15 is completely entered, the reciprocating swing motor is turned on to accelerate the uniform dissolution of the solution in the mixing tube 15. After the set swing time is completed, the pressure pump 16 pressurizes the inside of the mixing tube 15, thereby pressing the solution downward into the filter element 29 between the upper movable clamp seat 27 and the lower fixed clamp seat 28 for filtration. After the filtration is completed, the final liquid can be collected and provided to tumor patients who have difficulty swallowing.

[0043] When the interior needs to be cleaned, no medicine needs to be added. Only cleaning liquid or deionized water needs to be introduced into the liquid inlet 10. The first three-way valve 25 and the second three-way valve 36 can be used to clean the crushing component and the mixing component respectively.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
