Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic extraction, and more particularly to a device for ultrasonic extraction. Background Art

[0002] Ultrasonic extraction utilizes the cavitation, mechanical, and thermal effects of ultrasound to accelerate the release, diffusion, and dissolution of intracellular active substances, significantly improving extraction efficiency. The primary theoretical basis for ultrasonic extraction is the cavitation, thermal, and mechanical effects of ultrasound. When high-energy ultrasound waves act on a medium, the medium is torn into numerous small cavities, which then close instantaneously and generate instantaneous pressures of up to several thousand atmospheres, a phenomenon known as cavitation. The bursting of tiny bubbles in ultrasonic cavitation generates immense pressure, instantly rupturing the plant cell walls and the entire organism, shortening the disruption time. Simultaneously, the vibrations generated by ultrasound enhance the release, diffusion, and dissolution of intracellular substances, significantly improving extraction efficiency.

[0003] Ultrasonic extraction technology is widely used in chemical substance analysis. It is the most commonly used ultrasonic extraction method. By adding samples and extraction solvents to glass test tubes, ultrasonic extraction of target chemicals is performed and instrumental analysis is performed. However, since glass test tubes are often slender structures with a small bottom area, directly adding samples to glass test tubes often causes the samples to accumulate at the bottom of the glass test tube and cannot fully contact the extraction solvent. If the bottom area is increased, such as using a conical flask as a sample container for ultrasonication, it will inevitably occupy more ultrasonic pool area. Under the premise of the same ultrasonic pool area, the number of samples that can be ultrasonicated at one time will decrease.

[0004] Therefore, it is necessary to provide a device for ultrasonic extraction to at least partially solve the problems existing in the prior art. Summary of the Invention

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0043] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0044] like Figures 1-18 As shown, the present invention provides a device for ultrasonic extraction, comprising: a trough body that can be placed in a test tube 1, the trough body is used to hold a sample, and a wall surface of the trough body is provided with a penetration hole that allows the extraction solvent in the test tube 1 to pass through, and the diameter of the penetration hole is smaller than the particle diameter of the sample.

[0045] The sample placed in the trough body can be distributed according to the shape of the trough body, preventing sample accumulation and increasing the surface area of ​​the sample; the wall surface of the trough body is provided with penetration holes, so that the extraction solvent in the test tube 1 can fully contact with the sample. Compared with the sample accumulated at the bottom of the test tube 1, the contact area between the extraction solvent and the sample is increased, which can improve the efficiency of ultrasonic extraction; in addition, the diameter of the penetration hole is smaller than the particle diameter of the sample, which can prevent the sample from leaking out of the trough body and accumulating in the test tube 1.

[0046] The following three possible structures are provided for the specific structure of the tank:

[0047] like Figure 1-Figure 4 As shown, the first structure is as follows:

[0048] In one embodiment, the groove is formed between two sleeved cylinders, the opening of the first cylinder 2 located on the outside faces upward, and the opening of the second cylinder 3 located on the inside faces downward, and a groove is formed between the inner side of the first cylinder 2 and the outer side of the second cylinder 3;

[0049] The bottom of the second cylinder 3 is provided with an outwardly extending support portion 310 , and the support portion 310 is used to connect with the interior of the first cylinder 2 .

[0050] The support portion 310 at the bottom of the second cylinder 3 can be fixedly connected to the inner bottom of the first cylinder 2, for example, connected as an integral structure, or clamped. When the two are clamped and fixed, the support portion 310 at the bottom of the second cylinder 3 can be set to an elastic structure, and a protrusion is provided at the lower interior of the first cylinder 2. During installation, the support portion 310 elastically deforms inward when it moves down to the protrusion, and rebounds after moving to the bottom of the protrusion. In this way, the second cylinder 3 is clamped into the interior of the first cylinder 2, so that the annular area between the second cylinder 3 and the first cylinder 2 forms a trough for holding samples.

[0051] Furthermore, the difference between the inner diameters of the first cylinder 2 and the second cylinder 3 is greater than the particle diameter of the sample. After the first cylinder 2 is placed in the test tube 1, its top surface opening is set flush with the tube mouth of the test tube 1, and the height of the second cylinder 3 is lower than the height of the first cylinder 2.

[0052] In order to increase the contact area between the sample and the extraction solvent and facilitate the placement of the sample, the difference in inner diameter between the first cylinder 2 and the second cylinder 3 is greater than the particle diameter of the sample; when the sample is added, it is generally placed in the annular area formed between the first cylinder 2 and the second cylinder 3 and the top of the second cylinder 3, and then the first cylinder 2 and the second cylinder 3 are placed in the test tube 1, and the extraction solvent is added to the test tube 1. The liquid level of the extraction solvent should be higher than the second cylinder 3 so that the extraction solvent can immerse the sample.

[0053] Furthermore, the first cylinder 2 and the second cylinder 3 are both metal mesh cylinders.

[0054] The grid of the metal mesh cylinder serves as a penetration hole, the maximum size of which is smaller than the particle diameter of the sample. The extraction solvent can pass through the outside of the first cylinder 2 and directly contact the sample, or pass through the outside of the first cylinder 2 and enter the inside of the second cylinder 3, and then pass through the inside of the second cylinder 3 to enter the groove body in the annular area and contact the sample. In this way, the contact area between the sample and the extraction solvent is greatly improved, which can improve the efficiency of ultrasonic extraction.

[0055] Alternatively, the first cylinder 2 is a cellulose filter paper cylinder, and the second cylinder 3 is a metal mesh cylinder.

[0056] In addition to allowing the extraction solvent to pass through, the cellulose filter paper cartridge can also act as a filter to prevent impurities from entering the extracted solution. The filter paper allows the extraction solvent to penetrate.

[0057] like Figure 5-Figure 6 As shown, the second structure is as follows:

[0058] In one embodiment, the trough body is a rectangular parallelepiped box 4, comprising a top cover 410 and a box body 420 that are locked together. The sample is placed in the box body 420, and the box body 420 and the top cover 410 are metal meshes.

[0059] The metal mesh grid serves as a penetration hole, which is smaller than the particle diameter of the sample. The rectangular box 4 is preferably slender. After the sample is added to the box body 420, the top cover 410 is snapped onto the box body 420, and then the rectangular box 4 is placed in the test tube 1. The sample in the test tube 1 adapts to the shape of the rectangular box 4 and is distributed along the length direction of the test tube 1, and will not accumulate at the bottom of the test tube 1; then, the extraction solvent is added to the test tube 1. The liquid level of the extraction solvent is higher than the top of the rectangular box 4, so the extraction solvent can penetrate from any wall of the rectangular box 4 and fully contact with the sample, thereby increasing the contact area between the two and improving the extraction efficiency.

[0060] Furthermore, the sample is wrapped with filter paper and placed in the box body 420.

[0061] Before placing the sample into the box body 420 , the sample may be wrapped with filter paper. The filter paper plays a filtering role to prevent impurities from entering the extracted solution, and the filter paper allows the extraction solvent to penetrate.

[0062] like Figure 7-18 As shown, the third structure is as follows:

[0063] In one embodiment, the device further comprises: a support basket 5 for mounting the rectangular box 4, the support basket 5 comprising: a backboard 510, and support rods 520 disposed on the side of the backboard 510 and extending vertically; first limiting grooves 511 are evenly distributed on the backboard 510, and the rectangular box 4 is connected to the first limiting grooves 511 via a clamping member 6;

[0064] The top of the support rod 520 is provided with a bent portion 521 for hanging on the test tube 1;

[0065] When a plurality of rectangular parallelepiped boxes 4 are mounted on the support basket 5 , there are gaps between adjacent rectangular parallelepiped boxes 4 .

[0066] The entire support basket 5 may also be made of a metal mesh.

[0067] In order to facilitate the removal and placement of the rectangular box 4, in this embodiment, the rectangular box 4 in the second structure can be connected to the support basket 5 through the clamping part 6 (suitable for installing a rectangular box 4 on the backboard 510). When placing the rectangular box 4, the rectangular box 4 can be placed in the test tube 1 through the support rod 520, and the top of the support rod 520 is hung on the tube mouth of the test tube 1 through the bending part 521, which can also prevent the rectangular box 4 from colliding with the test tube 1 during ultrasonic extraction, thereby preventing damage to the test tube 1.

[0068] In order to further increase the contact area between the sample in the rectangular box 4 in the second structure and the extraction solvent, and to facilitate the removal and placement of the rectangular box 4, the size of the rectangular box 4 is reduced, and at least two rectangular boxes 4 are installed on the backboard 510. There are gaps between the multiple rectangular boxes 4, which can ensure that the sample in each rectangular box 4 can fully contact the extraction solvent; by placing the samples in multiple rectangular boxes 4 respectively, the exposed surface area of ​​the sample can be increased, so that the extraction solvent can penetrate from the wall of each rectangular box 4 and fully contact with the sample, thereby increasing the contact area with the extraction solvent and ensuring the extraction efficiency.

[0069] Furthermore, the clamping member 6 includes: an elastic body 610, a first limiting portion 620 of which is clamped to the first limiting groove 511 on the outer side of the lower part, and a second limiting portion 630 on the outer side of the upper part. The rectangular box 4 is provided with a second limiting groove 411 that is clamped to the second limiting portion 630, and a gap distance is left between the first limiting portion 620 and the second limiting portion 630.

[0070] Since the contact between the extraction solvent and the sample in the test tube 1 is static, it takes time for the sample located in the center of the rectangular box 4 to contact the extraction solvent. Therefore, in order to promote the contact between the sample located in the center of the rectangular box 4 and the extraction solvent, the sample located in the rectangular box 4 can generate a small movement to improve the contact effect between the sample and the extraction solvent.

[0071] Therefore, in this embodiment, the elastomer 610 on the clamping member 6 is utilized to enable the first limiting portion 620 and the second limiting portion 630 to be centered on the vertical center line of the elastomer 610, and to tilt in any direction away from the center under the driving action of an external force, and to tilt in the opposite direction again under the elastic recovery force of the elastomer 610, so that the rectangular box 4 can produce irregular tilting movement in any direction relative to the support basket 5, so that the sample particles inside it produce slight movement and change in position, thereby increasing the probability of the sample located in the center part contacting the extraction solvent, thereby increasing the contact area and contact effect, and promoting the extraction efficiency.

[0072] Furthermore, the first limiting portion 620 and the second limiting portion 630 are used to engage with the backboard 511 and the rectangular box 4 respectively, without affecting the fixation of the rectangular box 4 and the backboard 511 .

[0073] Furthermore, the elastic body 610 includes: an upper support piece 611, an upper deformation section 612, an intermediate support piece 613, a lower deformation section 614, and a lower support piece 615, which are arranged in sequence; the diameter of the intermediate support piece 613 is larger than the diameters of the upper support piece 611 and the lower support piece 615; the diameter of the middle portion of the upper deformation section 612 and the lower deformation section 614 is smaller than the diameter of the end portions thereof; and the outer side surfaces of the upper deformation section 612 and the lower deformation section 614 are arc-shaped surfaces;

[0074] The lower support piece 615 and at least half of the lower deformation section 614 are wrapped in the first limiting portion 620 , and the upper support piece 611 and at least half of the upper deformation section 612 are wrapped in the second limiting portion 630 .

[0075] The shapes of the upper deformable section 612 and the lower deformable section 614 enable them to bend and deform elastically. The lower support piece 615 and a portion of the lower deformable section 614 are wrapped within the first limiting portion 620, and the upper support piece 611 and a portion of the upper deformable section 612 are wrapped within the second limiting portion 630. This allows the first limiting portion 620 and the second limiting portion 630 to remain vertical when no external force is applied. The less the deformable section is wrapped by the limiting portion, the easier it is to deform. Therefore, in order to ensure stable support and a certain degree of deformation capability, at least half of the deformable section is wrapped within the limiting portion.

[0076] The upper support piece 611 is used to increase the connection strength between the elastomer 610 and the second limiting part 630, and the lower support piece 615 is used to increase the connection strength between the elastomer 610 and the first limiting part 620. In order to maintain the balance between the upper and lower deformations, the middle support piece 613 can play a limiting role when the deformation is too large; after the two limiting parts are respectively connected to the backboard 511 and the rectangular box 4, the clamping part 6 can play a stable supporting role for the rectangular box 4, and can produce bending deformation under the action of external force, thereby causing the rectangular box 4 to shake and changing the position of the sample inside it.

[0077] Furthermore, each of the first limiting portion 620 and the second limiting portion 630 includes two splicing unit bodies 640, each of which has an accommodating area 641 for accommodating the elastic body 610; a limiting plane 642 is provided at one end of the splicing unit body 640 away from the middle support piece 613, a boss 643 extends from the limiting plane 642, and a limiting block 644 extends outward from the boss 643;

[0078] The first limiting groove 511 is provided with a first notch 512 corresponding to the limiting block 644 on the first limiting portion 620 , and the second limiting groove 411 is provided with a second notch 412 corresponding to the limiting block 644 on the second limiting portion 630 .

[0079] The splicing unit body 640 is provided with an insert block 645 and a slot 646 on both sides of the accommodating area 641 , respectively. A first magnetic piece is provided at the end of the insert block 645 , and a second magnetic piece adsorbed to the first magnetic piece is provided in the slot 646 .

[0080] The first limiting portion 620 and the second limiting portion 630 are both composed of two splicing unit bodies 640, and the two splicing unit bodies 640 are fixed to the outside of the elastomer 610 by magnetic connection. Specifically, an insert block 645 and a slot 646 are respectively provided on one splicing unit body 640, and the insert block 645 and the slot 646 can be adsorbed to each other through the first magnetic sheet and the second magnetic sheet. Therefore, after the two splicing unit bodies 640 are put on the outside of the elastomer 610 and contact each other, the insert block 645 of one splicing unit body 645 is inserted into and adsorbed in the slot 646 of the other splicing unit body 646, and at the same time, the upper part or the lower part of the elastomer 610 is limitedly connected between the two splicing unit bodies 640.

[0081] When the first limiting portion 620 and the second limiting portion 630 are respectively engaged with the first limiting groove 511 and the second limiting groove 411, the boss 643 and the limiting block 644 on the first limiting portion 620 are respectively inserted into the first limiting groove 511 and the first notch 512. After being inserted into place, the first notch 512 is rotated to stagger the limiting block 644. Then, the top surface and the bottom surface of the first limiting groove 511 are engaged between the limiting plane 642 and the limiting block 644. The second limiting portion 630 is engaged with the second limiting groove 411 in the same manner, which will not be repeated here.

[0082] By the above method, the rectangular parallelepiped box 4 and the backboard 510 can be snap-fitted together. Moreover, after being snap-fitted and fixed, the limiting grooves can also limit the radial direction of the two splicing unit bodies 640 to prevent the two from being disengaged.

[0083] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0084] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.
