Description

Technical Field

[0001] This application relates to the field of natural plant extraction technology, and in particular to a plant extraction device with a filtration function. Background Technology

[0002] Chinese invention patent CN2024105983953 discloses a natural plant extraction device, which further squeezes and filters the essence from solid residue as the pressing plate approaches the filter plate. Currently, in the extraction of plant raw materials, for small samples, the samples are generally crushed and then filtered and centrifuged multiple times to separate the extract from the solid residue.

[0003] However, although the solid residue in the reagent tube will separate from the extract after centrifugation, a small amount of solid residue will still be mixed in with the extract during the transfer process. Therefore, in practice, the extract is usually transferred and further filtered before it can be used as a raw material, and the above steps are still quite cumbersome. Utility Model Content

[0004] This invention provides a plant extraction device with a filtration function. This plant extraction device can filter the extract during the centrifugation process, so that the extract raw material can be obtained after the centrifugation operation is completed.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A plant extraction device with filtration function includes an upper tube section, a lower tube section, and a filter bucket;

[0007] The upper and lower pipe sections are screwed together and fixed, and the bottom of the upper pipe section is provided with an on / off valve; the filter bucket is detachably installed at the connection between the upper and lower pipe sections, and the filter bucket is provided with filter holes adapted to the passage of liquid.

[0008] During centrifugation, the liquid in the upper tube passes through the filter bucket and enters the lower tube, while the solid residue in the extract remains above the filter bucket, and the pure extract can be stored in the upper tube.

[0009] Preferably, the on / off valve includes a hollow sliding cylinder, the upper end of the filter bucket is provided with a pin, the pin and the sliding cylinder are inserted into each other, the bottom of the upper pipe section is provided with a partition plate, and the sliding cylinder and the partition plate are slidably connected.

[0010] Preferably, the periphery of the sliding cylinder is provided with a liquid passage groove adapted for the extraction liquid to pass through.

[0011] When the sliding cylinder is lifted upwards, the liquid in the upper pipe section can enter the filter bucket through the liquid passage, be filtered, and then enter the lower pipe section.

[0012] Preferably, the upper end of the sliding cylinder is provided with a fixing ring, which is located on the upper side of the partition plate.

[0013] Preferably, the upper end of the sliding cylinder is provided with a positioning groove, and the upper end of the ejector pin is provided with a positioning block.

[0014] Preferably, the filter bucket is embedded in the upper opening of the lower pipe section, and correspondingly, the opening end of the lower pipe section is provided with a groove.

[0015] Preferably, the lower end of the upper pipe section is provided with a threaded ring, and correspondingly, the inner side of the open end of the lower pipe section is provided with an internal thread for screwing the threaded ring, and the lower end of the threaded ring abuts against the filter bucket.

[0016] Preferably, a sealing cap is provided at the upper opening of the upper pipe section.

[0017] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:

[0018] 1. During centrifugation, the plant extract in the upper tube is filtered through the filter bucket and then flows into the lower tube to be collected. This prevents the plant extract from coming into contact with solid residue again during the transfer process, thus avoiding impurities in the obtained plant extract raw material.

[0019] 2. The upper pipe section, filter bucket, and lower pipe section can be disassembled and installed, which facilitates cleaning after use. Attached Figure Description

[0025] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.

[0026] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Example

[0027] This embodiment provides a detailed explanation of the scheme for simulating a breeding farm:

[0028] A plant extraction device with filtration function includes an upper tube section 2, a lower tube section 11, and a filter bucket 10;

[0029] The upper pipe section 2 and the lower pipe section 11 are screwed together and fixed. An on / off valve is provided at the bottom of the upper pipe section 2. A filter bucket 10 is detachably installed at the connection between the upper pipe section 2 and the lower pipe section 11. The filter bucket 10 has filter holes adapted for liquid passage. The on / off valve includes a hollow sliding cylinder 7. A pin 8 is provided at the upper end of the filter bucket 10, and the pin 8 and the sliding cylinder 7 are inserted into each other. A partition plate 3 is provided at the bottom of the upper pipe section 2, and the sliding cylinder 7 and the partition plate 3 are slidably connected. A liquid passage groove 6 adapted for the extraction liquid is provided around the periphery of the sliding cylinder 7. A fixing ring 5 is provided at the upper end of the sliding cylinder 7, located above the partition plate 3. A threaded ring 4 is provided at the lower end of the upper pipe section 2. Correspondingly, the inner side of the open end of the lower pipe section 11 has an internal thread 9 for screwing the threaded ring 4 into place, and the lower end of the threaded ring 4 abuts against the filter bucket 10.

[0030] The connection relationship and working principle between the upper pipe section 2, the lower pipe section 11 and the filter hopper 10 are as follows:

[0031] The upper pipe section 2 and the lower pipe section 11 are connected by threads, such as Figure 2 and Figure 3 As shown, after the filter bucket 10 is placed into the opening at the upper end of the lower pipe section 11, the threaded ring 4 at the lower end of the upper pipe section 2 is screwed in, which can press the filter bucket 10 tightly, thereby preventing the filter bucket 10 from moving during centrifugation.

[0032] The working principle of the on / off valve is as follows:

[0033] When the upper pipe section 2 and the lower pipe section 11 are tightened, the ejector pin 8 will push the sliding cylinder 7 upward, so that the solid-liquid mixture in the upper pipe section enters the upper end of the filter bucket 10 after passing through the liquid passage 6 on the side of the sliding cylinder 7, thereby achieving centrifugation and filtration at the same time.

[0034] like Figure 4 As shown, the upper end of the sliding cylinder 7 is provided with a positioning groove 12, and the upper end of the ejector pin 8 is provided with a positioning block 13. To prevent the sliding cylinder 7 from moving upward along the liquid passage 6 and disengaging from the ejector pin 8, before centrifugation begins, the sliding cylinder 7 is pressed down with a glass rod until it engages with the positioning block 13 at the upper end of the ejector pin 8 to achieve initial fixation (the structure is similar to the engagement of a pen cap and pen body). When disassembling, the upper tube section 2 and the lower tube section 11 are rotated in the opposite direction, and the ejector pin 8 and the sliding cylinder 7 are pulled apart.

[0035] In this embodiment, the filter bucket 10 is embedded in the upper opening of the lower pipe section 11, and correspondingly, the opening end of the lower pipe section 11 is provided with a groove.

[0036] like Figure 1 As shown, a sealing cap 1 is installed at the upper opening of the upper pipe section 2. The function of the sealing cap 1 is to prevent liquid from spilling. Of course, the upper end of the sealing cap 1 is provided with a vent hole to discharge the gas generated in the pipe during the centrifugation process.
