[0059] When in use, first add the Chinese medicinal materials to be purified and an appropriate amount of water into the heating pot 3, then start the electric heater 2, the electric heater 2 heats the heating pot 3, so that the water in the heating pot 3 boils, thereby boiling the Chinese medicinal materials. After boiling for a certain period of time, turn off the electric heater 2, start the electric push rod 71, the telescopic rod of the electric push rod 71 contracts, drives the connecting plate 72 and the squeezing plate 73 to move downward, thereby driving the inclined plate 82 to move downward. Since the inclined plate 82 is connected to the right side with an inclined block, the inclined plate 82 moves downward to push the movable plate 81 to move right, and the compression spring 83 is compressed, so that the through hole on the movable plate 81 is connected to the liquid guide tube 6, so that the medicinal juice in the heating pot 3 flows through the liquid guide tube 6 to the filter screen 84 in the square block 5, and the squeezing plate 73 moves downward to the same The Chinese medicine residue in the heating pot 3 is squeezed so that the residual medicine juice in the residue can be fully squeezed out, and the filter net 84 can filter the residue so that the medicine juice flows into the liquid collecting box 4 for collection.

Finally, the box cover on the liquid collecting box 4 is opened, so that the medicine juice inside the liquid collecting box 4 can be taken out, and then the box cover is reset.

[0060] Example 2

[0061] On the basis of Example 1, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it also includes a replacement mechanism 9, which is used for centralized replacement of medicine residues. The replacement mechanism 9 includes a connecting column 91, a round tube tray 92, a pot cover 93, a medicine holding frame 94 and a column 95. The column 95 is welded on the left side inside the shell 1, and the pot cover 93 is slidably connected to the upper part of the column 95. The pot cover 93 is slidably connected to the extrusion plate 73. The pot cover 93 is slidably connected to the connecting column 91 on both the front and rear sides. Round tube trays 92 are welded to the bottom of the two connecting columns 91, and a medicine holding frame 94 is placed on the top of the round tube tray 92. The medicine holding frame 94 is located inside the heating pot 3. First, put the medicinal materials into the medicine holding frame 94, then add water into the heating pot 3, start the electric push rod 71, control the telescopic rod of the electric push rod 71 to shrink, drive the squeezing plate 73 to move downward, thereby driving the connecting column 91, the round tube tray 92, the pot cover 93 and the medicine holding frame 94 to move downward, so that the medicine holding frame 94 is immersed in water, so that the medicinal materials can be boiled, and after boiling, the squeezing plate 73 will continue to move downward to squeeze the medicine residue, so that the medicine juice in the medicine holding frame 94 flows into the heating pot 3, and then enters the collecting box 4 for collection, and the medicine juice is filtered. Afterwards, the telescopic rod of the electric push rod 71 is controlled to extend, driving the extrusion plate 73 to move upward and reset. When the extrusion plate 73 moves upward to contact the pot cover 93, it drives the pot cover 93 to move upward, and the pot cover 93 then drives the connecting column 91, the round tube tray 92 and the medicine holding frame 94 to move upward, so that the medicine holding frame 94 drives the medicine residue to move upward, and then the staff can replace the medicine holding frame 94. In this way, larger medicine residues can be replaced in a centralized manner, which is convenient for cleaning and reduces the trouble of replacing and cleaning medicinal materials. When it is necessary to continue to boil the medicinal materials, the above operation can be repeated.

[0062] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, it also includes a cleaning mechanism 10, which is used for collecting the drug residues in a centralized manner. The cleaning mechanism 10 includes a waste box 101, a baffle 102, a cylinder 103 and a push plate 104. A waste box 101 is slidably placed on the right side inside the square block 5. The waste box 101 is used for collecting the drug residues in a centralized manner. A baffle 102 is slidably connected to the right side inside the square block 5. The baffle 102 is used to block the drug juice. The baffle 102 is located on the left side of the waste box 101. A cylinder 103 is fixedly connected to the left side of the square block 5 by bolts, and a push plate 104 is connected to the right side of the telescopic rod of the cylinder 103. After the filtering of the medicinal juice is completed, medicinal residues will remain on the filter screen 84. The staff manually pulls the baffle 102 forward so that the baffle 102 no longer blocks the right side of the square block 5, and then starts the cylinder 103. The telescopic rod of the cylinder 103 extends and drives the push plate 104 to move to the right, so that the push plate 104 pushes the medicinal residues on the filter screen 84 into the waste box 101 for collection. In this way, the filter screen 84 can be cleaned to prevent the filter screen 84 from being blocked by the medicinal residues, and the medicinal residues can be collected in a centralized manner for easy cleaning. After cleaning, the telescopic rod of the control cylinder 103 is contracted to drive the push plate 104 to move to the left and reset, and then the baffle 102 is manually pushed backward and reset, so that the baffle 102 blocks the square block 5 again. In this way, when the Chinese medicine is boiled next time, the medicinal juice will not enter the waste box 101, and then the waste box 101 is taken out, the medicinal residues in the waste box 101 are cleaned, and the waste box 101 is reset.

[0063] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, it also includes a receiving mechanism 11, which is used to collect the residual medicine juice. The receiving mechanism 11 includes a liquid receiving tray 111, a hollow liquid collecting column 112 and a connecting rod 113. The middle part of the column 95 is rotatably connected to the connecting rod 113, and the liquid receiving tray 111 is welded to the front side of the connecting rod 113. The liquid receiving tray 111 is used to collect the residual medicine juice. The top of the liquid receiving tray 111 is concave, and a small hole is opened in the middle of the liquid receiving tray 111. Two clamping holes are opened at the bottom of the liquid receiving tray 111. When the medicine holding frame 94 is moved upward and out of the heating pot 3, the staff controls the connecting rod 113 to rotate, so that the liquid receiving tray 111 and the hollow liquid collecting column 112 rotate to the bottom of the medicine holding frame 94, so that the residual medicine juice in the medicine holding frame 94 can drip into the liquid receiving tray 111 for collection. Since the liquid receiving tray 111 is concave, the medicine juice will flow to the center position of the liquid receiving tray 111, and then flow to the hollow liquid collecting column 112 through the small holes on the liquid receiving tray 111 for collection. In this way, the waste of medicine juice can be avoided. Then, the hollow liquid collecting column 112 is rotated, the hollow liquid collecting column 112 is removed, and then the medicine juice in the hollow liquid collecting column 112 is poured out, and then the hollow liquid collecting column 112 is reset.

[0064] like Figure 1 , Figure 2 , Fig.11 and Fig.12 As shown, it also includes a sealing mechanism 12, which is used to fix the pot cover 93. The sealing mechanism 12 includes a fixed block 121 and a movable block 122. Four fixed blocks 121 are evenly welded on the upper part of the heating pot 3. The four fixed blocks 121 are rotatably connected with movable blocks 122. The movable block 122 is used to fix the pot cover 93. The movable block 122 is L-shaped. When boiling medicinal materials, the staff manually rotates the movable block 122 upward so that the movable block 122 buckles the pot cover 93. Since the upper part of the movable block 122 is made of rubber, the friction between the movable block 122 and the pot cover 93 can be increased, so that the pot cover 93 can be fixed, thereby increasing the airtightness of the heating pot 3 and reducing the speed of hot air overflow, so as to improve the efficiency of boiling medicinal materials. When the pot cover 93 needs to move upward, the movable block 122 is manually moved to separate from the pot cover 93.
