The liquid extraction end of the cleaning pump 44 is fixedly connected to the water storage tank 43 through a pipe. The liquid outlet end of the cleaning pump 44 is fixedly connected to the spray pipe 42 through a pipe. A spray head is fixedly connected to the outer surface of the spray pipe 42. When the cleaning pump 44 is started, the cleaning pump 44 extracts cleaning liquid from the water storage tank 43, transports it to the spray pipe 42 through a pipe, and then sprays it out from the spray head on the outer side of the spray pipe 42 to thoroughly rinse the stirring components such as the stirring rod 731.

[0027] A top plate 5 is provided above the support box 1. A guide box 6 is fixedly connected to the bottom surface of the top plate 5. A servo motor 61 is fixedly connected to one end of the guide box 6. A lead screw 62 is provided inside the guide box 6. One end of the lead screw 62 is fixedly connected to the output end of the servo motor 61. The end of the lead screw 62 away from the servo motor 61 is movably connected to the guide box 6 through a bearing. A lifting and stirring mechanism 7 is provided below the guide box 6. The lifting and stirring mechanism 7 includes a moving plate 71 that is slidably connected to the bottom of the guide box 6.

A guide groove matching the structural dimensions of the guide block 76 is provided on the bottom surface of the top plate 5. When the servo motor 61 at one end of the guide box 6 is activated, the servo motor 61 drives the lead screw body 62 to rotate. Because the sleeve block 75 on the top of the moving plate 71 is threadedly connected to the outer surface of the lead screw body 62, and the top of the moving plate 71 engages with the guide groove at the bottom of the top plate 5 via the guide block 76, the moving plate 71 moves horizontally along the guide box 6, driving the entire lifting and stirring mechanism 7 to move. The bottom surface of the moving plate 71... A lifting electric push rod 72 is fixedly connected. A first connecting plate 77 is fixedly connected to the telescopic end of the lifting electric push rod 72. A second connecting plate 78 is provided below the first connecting plate 77. A connecting screw 79 is threaded through the top surface of the first connecting plate 77.

The second connecting plate 78 is fixedly connected to the cover plate 73. The first connecting plate 77 is connected to the second connecting plate 78 through the connecting screw 79. A spring washer is provided between the first connecting plate 77 and the second connecting plate 78. The connecting screw 79 passes through the spring washer. The spring washer is connected to the stirring motor 74 to counteract the vibration of the stirring motor 74 and avoid affecting the normal use of the lifting electric push rod 72. A cover plate 73 is provided below the lifting electric push rod 72. The stirring motor 74 is fixedly connected to the top surface of the cover plate 73, and the stirring rod 731 is movably connected to the bottom surface of the cover plate 73 through a bearing. The top end of the stirring rod 731 is fixedly connected to the output end of the stirring motor 74. When the stirring motor 74 is started, the stirring motor 74 drives the stirring rod 731 to rotate, which fully mixes and stirs the plant extract and solvent in the corresponding extraction tank, accelerating the dissolution and extraction of effective components.

[0028] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the cleaning pump 44, servo motor 61, stirring motor 74, and lifting electric push rod 72, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected based on the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0029] Working principle: When using the equipment, the operator first checks whether each component is normal, ensures that the support box 1 is placed firmly, the first extraction tank 2 and the second extraction tank 3 are clean and free of impurities, the water storage tank 43 contains enough cleaning solution, and all pipes are tightly connected without leakage.

[0030] Furthermore, the operator places the herbal raw materials from which essential oils need to be extracted and the corresponding solvent into the first extraction tank 2. At this time, the stirring motor 74 is controlled to drive the stirring rod 731 to rotate, so as to fully mix and stir the plant extract and solvent in the first extraction tank 2 until they are evenly mixed.

[0031] Furthermore, controlling the retraction of the lifting electric push rod 72 drives the lifting of the cover plate 73, the stirring motor 74 and the stirring rod 731, controls the start of the servo motor 61, and the servo motor 61 drives the lead screw body 62 to rotate. Since the sleeve block 75 at the top of the moving plate 71 is threadedly connected to the outer surface of the lead screw body 62, the moving plate 71 moves horizontally along the guide box 6, driving the entire lifting and stirring mechanism 7 to move.

[0032] Furthermore, the baffle plate 10 is moved above the first extraction tank 2 to allow the solution inside the first extraction tank 2 to stand still. At this time, the lifting stirring mechanism 7 moves above the cleaning tank 41, and the extension and retraction of the lifting electric push rod 72 are controlled to drive the stirring rod 731 to move up and down. The cleaning pump 44 is started, and the cleaning pump 44 draws the cleaning liquid from the water storage tank 43 and delivers it to the spray pipe 42 through the pipeline. The liquid is then sprayed out from the spray head on the outside of the spray pipe 42 to thoroughly rinse the stirring rod 731.

[0033] Furthermore, after cleaning, the lifting and stirring mechanism 7 is moved to the top of the second extraction tank 3, and the herbal raw materials and corresponding solvents inside the second extraction tank 3 are mixed and stirred in the same way.

[0034] Furthermore, after the solution inside the first extraction tank 2 has separated into layers, the essential oil is at the top. After the lower layer solution is discharged, the essential oil is then discharged to complete the extraction of the essential oil. Similarly, the essential oil in the second extraction tank 3 is discharged.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
