DETAILED DESCRIPTION

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] Embodiments of the present utility model: Figure 1-Figure 3 As shown, a liquid extractor for a solid-liquid extraction system comprises a liquid extracting cylinder 1, one end of which is formed with a liquid extraction tube 2, the other end of which is connected with a piston assembly, a dredging device is fixedly arranged on the outer wall of the liquid extracting cylinder 1, a filter tip 3 is detachably mounted on the end of the dredging device, and the filter tip 3 is covered on the liquid extraction tube 2.

[0018] By pulling the piston assembly, the extract aroma raw material can be extracted through the liquid extraction tube 2. By setting the filter tip 3, the tobacco leaves can be isolated to prevent the extract aroma raw material from being mixed with solid matter. The clearing device is used to blow the tobacco leaves away from the filter tip 3 to prevent the tobacco leaves from clogging the filter tip 3.

[0019] In a specific embodiment, the liquid collection cylinder 1 is a cylindrical structure, the liquid extraction tube 2 is coaxial with the liquid collection cylinder 1, and the liquid extraction tube 2 and the liquid collection cylinder 1 are both made of borosilicate glass. By using borosilicate glass material, the liquid collection cylinder 1 and the liquid extraction tube 2 can be resistant to high temperature and chemical corrosion.

[0020] Furthermore, the piston assembly includes a plunger 4 and a piston rod 5. The plunger 4 is fixed at one end of the piston rod 5. The plunger 4 is installed in the liquid collection cylinder 1. The plunger 4 is slidably connected to the inner wall of the liquid collection cylinder 1. The other end of the piston rod 5 is formed with an end plate 6.

[0021] The liquid taking cylinder 1, the liquid drawing tube 2, the plunger 4 and the piston rod 5 together constitute a device for drawing out the extracted fragrance raw material, and its working principle is the same as that of the syringe.

[0022] Further, the dredging device includes an outer cylinder 7, an inner cylinder 8 and a first one-way valve 9. The end of the outer cylinder 7 close to the liquid extraction tube 2 is fixedly connected to the outer wall of the liquid extraction cylinder 1 through an annular connecting plate 10. The first one-way valve 9 is arranged on the annular connecting plate 10. The inner cylinder 8 is located between the outer cylinder 7 and the liquid extraction cylinder 1. An annular rubber sealing plate 11 is fixedly arranged at one end of the inner cylinder 8, and a first annular end plate 12 is fixedly arranged at the other end of the inner cylinder 8. For the convenience of operation, a second one-way valve is arranged on the annular rubber sealing plate 11, and a second annular end plate 14 is fixedly arranged at the end of the outer cylinder 7.

[0023] Outer cylinder 7 and annular connecting plate 10 are integrally formed with liquid taking cylinder 1, and they are made of the same material. Inner cylinder 8 can select plastic material with lower price. First one-way valve 9 and second one-way valve are commercially available products, can directly buy and obtain, and second one-way valve is smaller in size and is not shown in the drawings. Second one-way valve is used for air intake, and first one-way valve 9 is used for exhaust.

[0024] Further, the inner diameter of the inner cylinder 8 is larger than the outer diameter of the liquid taking cylinder 1, and the outer diameter of the inner cylinder 8 is smaller than the inner diameter of the outer cylinder 7. The filter tip 3 is threadedly connected to the end of the outer cylinder 7, and a plurality of elongated through holes 13 are formed on the filter tip 3.

[0025] The long through hole 13 is used to allow the extract and aroma raw materials to enter the filter 3 while the tobacco leaves are isolated outside the filter 3. It should be noted that the filter 3 and the outer cylinder 7 can be connected by snap-fitting or other convenient disassembly methods in addition to threaded connection.

[0026] The working principle of the utility model is as follows: when in use, the end plate 6 is pressed to push the plunger 4 to the bottom of the liquid collection cylinder 1 through the piston rod 5, so that the plunger 4 contacts the liquid extraction tube 2, and then the utility model is inserted into the round-bottomed flask to observe whether the long strip through hole 13 on the filter tip 3 is wrapped by tobacco leaves. If not, the end plate 6 can be pulled up to drive the plunger 4 to move up through the piston rod 5, and the extract fragrance raw material is drawn into the liquid collection cylinder 1 through the liquid extraction tube 2. If the long strip through hole 13 on the filter tip 3 is wrapped by tobacco leaves, it is necessary to pull the inner cylinder 8 through the first annular end plate 12, and the air enters the space between the outer cylinder 7 and the liquid collection cylinder 1 through the second one-way valve. After pulling up to the right position, the first annular end plate 12 is pressed down, and the annular rubber sealing plate 11 moves down and squeezes the air. The air is discharged into the filter tip 3 through the first one-way valve 9, and then discharged into the round-bottomed flask through the long strip through hole 13. Repeated operations can blow away the tobacco leaves wrapped on the filter tip 3.

[0027] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
