The ethanol steam discharged from the steam outlet of the sealing cover 310 sequentially flows into the cavity of the steam collection frame 421 through the steam guide pipe 410 and the steam collection pipe 423 and continuously flows into the liquefaction area of the liquefaction pipe 425 under the action of pressure, when the ethanol steam contacts the spiral guide rail 4263 arranged in the liquefaction area, the ethanol steam continuously flows downwards through the spiral guide rail 4263, the cooling pipe 4262 cools and dissipates the heat of the ethanol steam under the action of the cooling pipe 4262 while the ethanol steam moves downwards until the ethanol steam is liquefied and flows into the liquid collection frame 422, and the liquefied ethanol solvent is discharged through the liquid outlet pipe 424.

The ethanol solvent discharged from the liquid outlet pipe 424 flows into the pump housing 441, the pressurizing motor 443 drives the driving rotary disc 444 to rotate, the driving rotary disc 444 drives the guide block 445 to move downwards in the vertical direction through the matching of the sliding block and the sliding groove, and the guide block 445 moves and pulls the pressurizing piston 447 to synchronously move downwards.

When the booster piston 447 vertically moves downwards, the air inlet plate 4473 seals a second pressure reducing hole at the bottom of the booster piston 447 under the elastic force of the air inlet spring 4474, and the pressure in the chamber of the pump shell 441 is gradually increased by pressing air in the chamber of the pump shell 441 while the booster piston 447 moves downwards, so that the rate of the ethanol solvent in the pump shell 441 flowing into the extraction cylinder 310 through the one-way valve 450 and the return pipe 460 in sequence is increased;

when the heating time reaches a preset time, the heating of the extraction cylinder 310 is stopped, the plugging motor 3441 starts to operate, the transmission shaft 3443 is driven to rotate by the first transmission member 3442, the transmission shaft 3443 drives the drive shaft 3446 to rotate sequentially through the first gear 3444 and the second gear 3445, so that the plugging plate 3413 starts to rotate, when the sealing plate 3413 unblocks the first filtering holes arranged in the filtering plate 3441, the plugging plate 3413 stops rotating, the plugging assembly 341 is switched from the plugging state to the flow-through state, and the extraction liquid in the extraction cylinder 310 flows out sequentially through the first filtering holes of the filtering plate 3441 and the second filtering holes of the plugging plate 3413.

The extract discharged through the first filtering hole of the filtering plate 3441 and the second filtering hole of the blocking plate 3413 flows into the collecting hopper 510 under the action of gravity, at this time, the liquid discharge motor 521 starts to operate, and drives the rotary valve core 525 to rotate around the axis of the rotary valve core 525 through the driving rod, when the liquid outlet hole 5251 is communicated with the extract collecting nozzle 524, the liquid discharge motor stops operating and stops rotating the rotary valve core 525, and the extract flows out of the extract collecting nozzle 524 and is collected.

After the extract liquid is collected, the blocking plate 3413 continues to rotate, when the blocking plate 3413 blocks a first filtering hole arranged in the filtering plate 3441, the blocking plate 3413 stops rotating, the blocking assembly 341 is switched from the flowing state to the blocking state, the medicine crushing motor 3431 starts to work, the gear shaft 3433 is driven to rotate through the second transmission member 3432, the gear shaft 3433 drives the medicine crushing shaft 3422 to rotate through the third gear 3434 and the fourth gear 3435 in sequence, and therefore the medicine crushing knife 3421 rotates around the axial direction of the medicine crushing shaft 3422 and crushes the traditional Chinese medicine extracted from the extracting cylinder 310 through the medicine crushing knife 3421.

After the extracted traditional Chinese medicine materials are smashed by the medicine smashing knife 3421, the solvent control valve 350 is opened and distilled water is supplied to the extraction cylinder 310, and the solvent control valve 350 is closed until the distilled water amount in the extraction cylinder 310 reaches a preset value;

the plugging plate 3413 continues to rotate until the plugging plate 3413 removes the plugging of the first filtering hole arranged on the filtering plate 3441, at this time, the plugging plate 3413 stops rotating, the plugging component 341 is switched to the circulation state from the plugging state, and the smashed medicine residues and the distilled water flow out through the first filtering hole arranged on the filtering plate 3441 and the second filtering hole arranged on the plugging plate 3413.

Meanwhile, the liquid discharge motor 521 starts to operate and drives the rotary valve core 525 to rotate, when the liquid outlet hole 5251 is communicated with the slag discharge nozzle 523, the liquid discharge motor 521 stops operating and stops rotating the rotary valve core 525, and a mixture of the traditional Chinese medicine residues and the distilled water flowing out of the first filtering hole arranged on the filtering plate 3441 and the second filtering hole arranged on the plugging plate 3413 is discharged and collected from the slag discharge nozzle 523.
