[0021] A trigger assembly is set between the spokes of the toothed disc and the piston rod. Whenever it rotates to bring the trigger seat to the bottom side of the lifting wheel of the trigger assembly, the lifting wheel will be crushed to make the lifting wheel rise, and the lifting wheel will bring the piston rod up, and the piston rod will drag the piston upward. The upward action of the piston will form an upward suction force in the inner immersion cylinder, and the upward suction force will be used to lift the liquid filtered into the inner immersion cylinder upward. After the third-level filtration of the third hole, the liquid reaches the top of the secondary immersion seat, and is sent to the discharge pipe through the top inclined surface of the secondary immersion seat. Finally, it is discharged outward from the discharge pipe. The liquid obtained after the reactants are filtered through the above multi-stage filtration is of high quality. Therefore, in order to detect the liquid after discharge, a piston-type discharge structure is set. The liquid is discharged once every rotation of the toothed disc 16, and the quality of the liquid after each discharge can be observed without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0030] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
[0031] In one embodiment, Figure 1-Figure 7 As shown:

A top cover 9 is installed at the end, and a mounting hole 10 communicating with each other from top to bottom is opened in the middle of the top cover 9. The bottom end of the inner immersion cylinder 8 is fixed to the bottom of the cavity of the mixing tank 1, and the top of the inner immersion cylinder 8 extends to the top of the top cover 9 through the mounting hole 10. A space 11 is left between the inner immersion cylinder 8 and the cavity wall of the through cavity 7. A large number of second holes 12 are opened on the inner immersion cylinder 8. The inner immersion cylinder 8 communicates with the space 11 inside and outside through the second holes 12. A piston 13 is provided in the inner immersion cylinder 8, and a piston rod 14 is connected to the piston 13. The other end of the piston rod 14 extends from the top of the inner immersion cylinder 8 to the outside of the cylinder, and the top of the inner immersion cylinder 8 is connected to a discharge pipe 15;
[0033] A toothed disc 16 is installed on the inner immersion cylinder 8. The top end of the agitator 2 reaches above the top cover 9 and is meshed with the toothed disc 16 through a gear 17. The piston rod 14 extends to one end of the inner immersion cylinder 8, bends downward, and approaches the top cover 9. A trigger assembly 18 located on the rotation path of the toothed disc 16 is installed.
[0034] The trigger assembly 18 includes a spoke 19 formed on the toothed disc 16, a trigger seat 20 installed on the spoke 19, and a lifting wheel 21 installed on the end of the piston rod 14 close to the top cover 9. The trigger seat 20 is provided with an inclined surface 22. When the inclined surface 22 rotates to contact the lifting wheel 21, the lifting wheel 21 is pushed to drive the piston rod 14 to rise. When the inclined surface 22 rotates to separate from the lifting wheel 21, the lifting wheel 21 drives the piston rod 14 to descend.
[0035] A secondary immersion seat 23 is fixed in the inner immersion cylinder 8, and the secondary immersion seat 23 is located above the second hole 12. A large number of third holes 24 are vertically opened on the secondary immersion seat 23. The piston 13 is located above the secondary immersion seat 23. The top of the inner immersion cylinder 8 is closed. A return spring 27 is connected between the top of the piston 13 and the top of the inner immersion cylinder 8. The discharge pipe 15 is flat on the top cover 9, and the liquid inlet end of the discharge pipe 15 enters the inner immersion cylinder 8 and is located between the piston 13 and the secondary immersion seat 23.
[0036] The diameter of the third hole 24 is smaller than the diameter of the second hole 12 .
[0037] like Figure 2 , Figure 7 As shown, a feed hole 25 is opened on the top cover 9 , and the feed hole 25 is located on the outer side of the toothed disc 16 .
[0038] There are a plurality of agitators 2, which are arranged in a circular array around the periphery of the immersion seat assembly 3, thereby improving the stirring efficiency and quality. During actual assembly, a protective cover is installed on the top cover 9 to cover the gears 17 and the toothed disc 16 inside, in order to improve safety and to protect the toothed disc 16 and the gear 17. A feeding hole connected to the feeding hole 25 is reserved on the protective cover, or a feeding pipe connected to the feeding hole 25 is installed on the protective cover.
[0039] A sleeve 26 is fixed to the bottom of the mixing tank 1, and the sleeve 26 is vertically upward. The bottom end of the inner immersion cylinder 8 can be detachably inserted into the sleeve 26. A damping rubber ring is provided on the inner wall surface of the sleeve 26, so that the bottom end of the inner immersion cylinder 8 is damped and locked.
[0040] Working principle and effect: Add the prepared reactants such as base oil and flavor into the mixing tank 1 through the feed hole 25, start the motor to drive the toothed disc 16 to rotate, the toothed disc 16 drives all the gears 17 to rotate, and the gears 17 drive all the stirrers 2 to rotate. Since these stirrers 2 are distributed in a circular array in the mixing tank 1, and the stirring radius of the stirrers 2 is close to the center of the mixing tank 1, when these stirrers 2 rotate at the same time, it is equivalent to thoroughly mixing the reactants in each area of the mixing tank 1, thereby improving the mixing efficiency, eliminating the stirring dead angle, and improving the mixing quality;
[0041] In addition, when these agitators 2 rotate, the reactants will generate a surge effect in the mixing tank 1, and under the action of the surge effect, they will frequently collide with the outer immersion tube 4, and generate a water pressure effect between the outer wall of the outer immersion tube 4. The water pressure effect is used to intercept impurities in the reactants in the mixing tank 1, and the filtered liquid passes through the first hole 5 into the glass fiber seat 6, and after secondary filtration by the glass fiber seat 6, it enters the space 11, and finally quickly penetrates into the inner immersion tube 8 through the second hole 12.
[0042] In addition, Figure 2 , Figure 4 as well as Figure 6As shown, the size of the toothed disc 16 is much larger than the size of each gear 17, so when the large toothed disc 16 rotates with the small gear 17, the gear 17 can rotate the agitator 2 at a high speed, and whenever the spokes 19 on the toothed disc 16 rotate to bring the trigger seat 20 to the bottom side of the lifting wheel 21, the lifting wheel 21 is crushed by the inclined surface 22. According to the inclined guidance of the inclined surface 22, the lifting wheel 21 is lifted, and the lifting wheel 21 lifts the piston rod 14, and the piston rod 14 drags the piston 13 upward. The upward action of the piston 13 forms an upward suction force in the inner immersion cylinder 8, and the upward suction force is used to lift the liquid filtered into the inner immersion cylinder 8 upward, and the liquid reaches the second immersion cylinder 8 after three-stage filtration through the third hole 24. The liquid is sent to the discharge pipe 15 through the top inclined surface of the secondary immersion seat 23, and finally discharged outwardly from the discharge pipe 15. The liquid obtained after the reactants are filtered through the above multi-stage filtration has a high quality. Each time the piston 13 rises, the reset spring 27 is compressed and shortened once, and the reset spring 27 will store elastic force. Each time the spoke 19 brings the trigger seat 20 away from the lifting wheel 21, the reset spring 27 will release the elastic force and push the piston 13 to automatically descend once, until the spoke 19 brings the trigger seat 20 to contact the lifting wheel 21 again, and the piston 13 is raised again by the piston rod 14, and the liquid is sucked into the discharge pipe 15 by negative pressure, and discharged outwardly through the discharge pipe 15 once.
[0043] In summary, in order to improve the mixing efficiency between the reactants, a plurality of agitators 2 are arranged in the mixing tank 1; in order to make these agitators 2 rotate synchronously and at high speed, a large-sized toothed disc 16 is arranged above the mixing tank 1 to drive them to rotate at the same time; in order to obtain a liquid with higher quality and purity, a multi-layer filtering and intercepting function is arranged; in order to detect the liquid after discharging, a piston-type discharging structure is arranged, and the liquid is discharged once every time the toothed disc 16 rotates one circle, and the quality of the liquid after each discharging can be observed without stopping the machine.
[0044] like Figure 4 As shown, the top of the secondary immersion seat 23 is a slope, and the inclination direction of the slope is toward the liquid inlet end of the discharge pipe 15. The liquid lifted to the secondary immersion seat 23 by the piston 13 will flow into the discharge pipe 15 better along the top slope of the secondary immersion seat 23, ensuring that the discharge pipe 15 is finally discharged outward.
[0045] After the inner immersion cylinder 8 has been used for a period of time, it is removed upward through the mounting hole 10. At the same time, the glass fiber seat 6 is removed upward through the mounting hole 10. Since the glass fiber seat 6 is a ring-shaped member composed of multiple pieces of glass fibers compressed together, it is destroyed from the internal cavity 7 and then disassembled upward through the mounting hole 10. In the same way, the new glass fiber seat 6 is reinstalled layer by layer into the outer immersion cylinder 4.
[0046] The present invention also provides a process for extracting plant essential oil from makeup remover oil, comprising the following extraction steps:
[0047] Step S01, adding 22 ml of jojoba oil to every 50 ml of grape seed oil according to the measurement, mixing and treating with the makeup remover plant essential oil extractor to obtain a base oil, adding medicated soap to the base oil in proportion, and the medicated soap component enables the base oil to resist folliculitis;
[0048] Step S02, adding the reactants obtained in step S01 into a mixing tank 1, and adding water, seaweed mud, moisturizer, emulsifier, and chamomile essential oil into the mixing tank 1 according to specific gravity to obtain a reactant;
[0049] Step S03, stirring the reaction materials in step S02 through the mixing tank 1, filtering through the soaking seat assembly 3 in the mixing tank 1 to obtain the plant essential oil product (liquid preparation), and using the trigger assembly 18 in the mixing tank 1 to finally discharge the plant essential oil product through the discharge pipe 15.
