[0002] The existing eucalyptus leaf extraction is mostly assisted by manual operation. The eucalyptus leaves are arranged and then put into a container, and organic solvent is poured into the container for soaking. During the soaking, the eucalyptus leaves need to be manually turned and kneaded to break the cell walls of the eucalyptus leaves by external force, so that the essential oil is fully dissolved in the solvent. After the soaking is completed, the eucalyptus leaves and the solvent are manually separated to complete the extraction process.

[0003] In the prior art, the manual extraction method has high labor intensity and low extraction efficiency. The force and frequency of manual kneading are difficult to keep uniform, which leads to insufficient eucalyptus leaf essential oil precipitation and uneven extraction rate.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-6 The present application provides a technical solution:

[0028] A eucalyptus leaf extraction device for eucalyptus oil extraction includes a lower tank 1 and an upper tank 2, which are threaded together. During extraction, the upper tank 2 and lower tank 1 must be connected to each other to ensure the sealing of the extraction environment. A connecting plate 4 is connected to the upper end of the upper tank 2. After the extraction equipment is assembled, the connecting plate 4 serves as a fixing mechanism. A lifting bar 17 is slidably connected to one side of the connecting plate 4, and a moving bar 15 is slidably connected to the lifting bar 17. A sloping groove plate 14 is connected to one side of the connecting plate 4, and the sloping groove plate 14 has sloping grooves. One end of the moving bar 15 is slidably connected to the inclined groove of the inclined groove plate 14 via the sliding button 16. A transmission component is provided below the lifting bar 17 to drive the lifting bar 17 to move up and down. One end of the lifting bar 17 is connected to the rotating seat 12, and the rotating seat 12 is connected to the rotating rod 6. The lower end of the rotating rod 6 is connected to the extraction frame 10. The extraction frame 10 has a filter tank for the entry of organic solvent. This structure can intercept eucalyptus leaves without interfering with the entry and discharge of organic solvent. The extraction frame 10 is connected to a pressing mechanism for kneading the eucalyptus leaves in the extraction frame 10.

[0029] Specifically, such as Figure 3 As shown, the upper tank 2 is connected to the mounting plate 7 via the sealing cover 3. The mounting plate 7 is connected to the connecting plate 4. When the sealing cover 3 is threaded onto the upper tank 2, the sealing cover 3 can press the mounting plate 7 into the opening above the upper tank 2.

[0030] Specifically, such as Figure 3 As shown, the lower end of the mounting plate 7 is connected to the upper tube 8, and the upper end of the connecting plate 4 is connected to the lower tube 9. One end of the upper tube 8 is threaded to one end of the lower tube 9. By setting the upper tube 8 and the lower tube 9, the flexibility of the connection of the connecting plate 4 is improved. The detachable structure of the connecting plate 4 makes it convenient to inspect and repair the structure connected to the connecting plate 4.

[0031] Specifically, such as Figure 4 As shown, a U-shaped frame 5 is connected to one side of the connecting plate 4, and a sliding clamp 18 is slidably connected to the U-shaped frame 5. The sliding clamp 18 is fixedly connected to one side of the lifting bar 17, and both ends of the U-shaped frame 5 are fixedly connected to one side of the connecting plate 4. The stability of the lifting structure of the lifting bar 17 is improved by setting the sliding clamp 18.

[0032] Specifically, such as Figure 5 and Figure 6As shown, the transmission component includes a motor 13, which is fixedly connected to the U-shaped frame 5. The output end of the motor 13 is connected to a turntable 23, and a traction bar 25 is eccentrically rotatably connected to the turntable 23. The other end of the traction bar 25 is rotatably connected to a traction block 26, which is fixedly connected to a lifting bar 17. When the motor 13 is running, it can drive the lifting bar 17 to perform vertical reciprocating lifting. The speed at which the motor 13 drives the turntable 23 to rotate is related to the extraction frequency. When the turntable 23 is at a suitable rotation speed, it can fully improve the entry of organic solvent into the eucalyptus leaves, ensuring efficient extraction of essential oil.

[0033] Specifically, such as Figure 5 As shown, a deflection bar 28 is connected to the upper end of the rotating rod 6. A crank handle 29 is rotatably connected to one end of the deflection bar 28. The crank handle 29 is rotatably connected to the moving bar 15. A limit ring 27 is connected to the rotating rod 6. By setting the deflection bar 28 and the crank handle 29, when the moving bar 15 and the lifting bar 17 are relatively displaced, the extraction frame 10 can be driven to rotate, thereby realizing the subsequent organic solvent ejection and immersion, and the kneading of eucalyptus leaves, thus improving the extraction quality.

[0034] Specifically, such as Figure 5 As shown, the pressing mechanism includes a pressing plate 11, which is sleeved on the rotating rod 6. A spring 20 is connected to the upper end of the pressing plate 11, and a sleeve 19 is connected to the upper end of the spring 20. The sleeve 19 is fixedly connected to one side of the U-shaped frame 5. Both the spring 20 and the sleeve 19 are sleeved on the rotating rod 6. The pressing plate 11 is used to limit the eucalyptus leaves in the extraction frame 10. The spring 20 is used to achieve different pressing effects, so that eucalyptus leaves of a certain volume range placed in the extraction frame 10 can be extracted. The spring 20 can resist the external force that drives the pressing plate 11 to rotate, thereby achieving the effect of kneading the eucalyptus leaves inside when the extraction frame 10 rotates.

[0035] Specifically, such as Figure 5 As shown, a handle 21 is connected to the upper end of the pressing plate 11, a kneading strip 24 is connected to the extraction frame 10, and a screw 22 is threaded onto the extraction frame 10. The handle 21 facilitates the operation of the pressing plate 11, and the kneading strip 24 can be connected to the lower end of the pressing plate 11 to improve the kneading effect. The screw 22 set inside the extraction frame 10 can limit the pressing plate 11 and prevent the pressing plate 11 from separating from the extraction frame 10.

[0036] In summary, the eucalyptus leaf extraction device for eucalyptus oil extraction provided in this embodiment requires the following steps: First, an organic solvent needs to be injected into the lower tank 1 before extraction. Then, eucalyptus leaves to be extracted are added to the extraction frame 10. To add the leaves, simply pull the handle 21 upwards to separate the pressing plate 11 from the extraction frame 10. At this time, the spring 20 is compressed. Then, eucalyptus leaves are added to the extraction frame 10. After addition is complete, the handle 21 is released, and the spring 20 drives the pressing plate 11 to reset, ensuring that the pressing plate 11 can press the eucalyptus leaves into the extraction frame 10.

[0037] After the pressing plate 11 is reset, screws 22 are connected to the outside of the extraction frame 10. The connected screws 22 can limit the pressing plate 11, ensuring that the pressing plate 11 cannot be separated from the extraction frame 10, thereby keeping the eucalyptus leaves well within the extraction frame 10.

[0038] Then, the installation plate 7 is inserted into the upper end of the upper tank 2, and the sealing cover 3 is threadedly connected to the upper tank 2, thereby connecting the installation plate 7 and the upper pipe 8. The sealing cover 3 can press the installation plate 7 onto the upper tank 2. Then, the lower pipe 9 is threadedly connected to the upper pipe 8, thus completing the preparation work for the upper tank 2 and the lower tank 1 before the leaching operation.

[0039] The upper tank 2 and the lower tank 1 are connected by threads. The control panel on the outside of the upper tank 2 is operated to adjust the heating unit inside the tank so that the tank is at a suitable extraction temperature, which is conducive to the extraction of essential oil from the eucalyptus leaves. The heating unit and control panel are direct references to existing technology and will not be described in detail here.

[0040] Then, operate the control panel to start the motor 13. The motor 13 drives the turntable 23 to rotate. The turntable 23, together with the traction bar 25, can push the lifting bar 17 to move vertically. During this process, the sliding clamp 18 on one side of the lifting bar 17 can slide in the vertical part of the U-shaped frame 5.

[0041] When the lifting bar 17 rises, it can simultaneously drive the rotating rod 6 on one side of the lifting bar 17 to rise and fall, thereby pulling the extraction frame 10 from the state of being immersed in organic solvent to away from the organic solvent. When pulling it up, since the sleeve 19 is fixedly connected to one side of the U-shaped frame 5, the height of the sleeve 19 remains unchanged during the extraction operation. When the height of the extraction frame 10 rises, the sleeve 19 can press the pressing plate 11 down through the spring 20, thereby further pressing the eucalyptus leaves in the extraction frame 10, achieving the effect of quickly squeezing out the organic solvent between the eucalyptus leaves in the extraction frame 10, and also accelerating the dissolution of the essential oil in the eucalyptus leaves into the organic solvent.

[0042] When the lifting bar 17 moves upward, it can synchronously drive the moving bar 15 to move upward. At this time, one end of the moving bar 15 will be limited by the inclined groove on the inclined plate 14, thereby driving the moving bar 15 to slide on the lifting bar 17. At this time, the moving bar 15 can push the crank 29 to move, and the crank 29 acts on the deflection bar 28, thereby driving the rotating rod 6 connected to one end of the deflection bar 28 to rotate. That is, when the extraction frame 10 moves upward, the extraction frame 10 itself will also rotate, which can accelerate the ejection of organic solvents from the eucalyptus leaves.

[0043] As the extraction frame 10 rotates, the pressing plate 11 pressing above the eucalyptus leaves resists the rotation of the extraction frame 10 under the action of the spring 20, thereby allowing the eucalyptus leaves inside the extraction frame 10 to be kneaded. This process also occurs when the extraction frame 10 moves downward, thereby improving the cell wall destruction effect inside the eucalyptus leaves, accelerating the extraction of essential oils, and improving the structural destruction effect of the eucalyptus leaves in conjunction with the kneading strip 24.

[0044] When the motor 13 rotates and drives the extraction frame 10 to be immersed in the organic solvent, the organic solvent can re-enter between the eucalyptus leaves, so that the essential oil can be fully dissolved in the organic solvent. After running for a period of time, the extraction of eucalyptus leaves in the extraction frame 10 is completed. Then, the upper tank 2 can be disassembled to replace the eucalyptus leaves in the extraction frame 10 and carry out the next set of eucalyptus leaf extraction operations.

[0045] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
