Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 6 The present invention provides a structural diagram of an embryo gene high-efficiency extraction and purification device according to Embodiment 1. This device includes: a frame 10 and a stirring device 30, a magnetic suction device 40, and a purification tank 50 mounted on the frame 10. The purification tank 50 includes a centrifugal filter tank 501 and a collection tank 502. The centrifugal filter tank 501 is sleeved on the outside of the collection tank 502. The collection tank 502 is an inverted cone shape. The interior of the centrifugal filter tank 501 is also an inverted cone shape, and the space between the interior of the centrifugal filter tank 501 and the outer walls of both sides of the collection tank 502 is... An equidistant annular gap is formed; both the centrifugal filter 501 and the collection tank 502 are provided with through holes at their tops to allow the stirring device 30 to be inserted into the collection tank 502; the collection tank 502 is elastically connected vertically to the centrifugal filter 501, and the centrifugal filter 501 is elastically mounted vertically in the frame 10; a lifting mechanism mounted on the frame 10 is used for the stirring device 30 and the magnetic attraction device 40 to move vertically; a power device mounted on the frame 10 is used to drive the collection tank 502 to rotate and drive the centrifugal filter 501 to jump vertically during extraction.

[0034] In use, the raw material liquid and medicine to be processed are added to the collection tank 502. Then, the lifting mechanism drives the stirring device 30 and the magnetic suction device 40 to move downwards, so that the stirring device 30 is inserted into the collection tank 502, and the bottom of the stirring device 30 abuts against the collection tank 502, causing the collection tank 502 to move downwards. The outer side and bottom of the collection tank 502 abut against the inner wall of the centrifugal filter tank 501, thus preventing the raw material liquid from being inside the centrifugal filter tank 501 and facilitating contact with the stirring device 30. At the same time, the stirring device 30 rotates to stir, and the collection tank 502 also rotates during the stirring process, thus increasing the mixing uniformity of the raw material liquid and medicine and the shearing intensity, thereby improving the gene extraction efficiency. The power unit drives the centrifugal filter 501 to bounce up and down along its axis, causing the annular gap formed between the inner wall of the centrifugal filter 501 and the outer wall of the collection tank 502 to periodically contract and expand. This generates a pulsating shearing effect on the liquid in the gap, enhancing cell lysis and impurity separation. At the same time, the filter holes on the centrifugal filter 501 are used to divide and impact the raw material liquid, allowing it to effectively contact the stirring device 30 and improve the extraction efficiency. After extraction, the lifting mechanism drives the stirring device 30 and the magnetic suction device 40 to rise, causing the stirring device 30 to leave the centrifugal filter 501. Then, the collection tank 502 rotates rapidly, causing the decomposed liquid to be centrifuged and broken down before entering the centrifugal filter 501.

[0035] This invention combines extraction and purification into a single device, improving gene extraction efficiency. During extraction, the power unit drives the centrifugal filter 501 to move up and down along its axis, causing the annular gap between the inner wall of the centrifugal filter 501 and the outer wall of the collection container 502 to periodically contract and expand. This generates a pulsating shearing effect on the liquid within the gap, enhancing cell lysis and impurity separation. Simultaneously, the filter holes on the centrifugal filter 501 are used to segment and impact the raw material liquid, allowing it to effectively contact the stirring device 30, further improving extraction efficiency.

[0036] like Figure 2 and Figure 4 As shown, the present invention also includes a reaction chamber 60, which is connected to the bottom of a collection tank 502 via a connecting pipe. A portion of the decomposed liquid enters the reaction chamber 60 through a centrifugal filter 501, and then a reaction solution is added to the reaction chamber 60 to react, thoroughly mixing and reacting to generate a purified solution, thus achieving the purification effect.

[0037] like Figure 2 and Figure 4As shown, the stirring device 30 includes a driving unit and a stirring consumable 301. The stirring consumable 301 is mounted on the driving unit, and the driving unit is used to drive the stirring consumable 301 to rotate. The stirring consumable 301 is used to be inserted into the collection bucket 502. The magnetic attraction device 40 includes a mounting unit and a magnetic rod 401. The magnetic rod 401 is used to be inserted into a blind hole on the stirring consumable 301.

[0038] In some embodiments, a plurality of elastic telescopic rods 503 are provided on the upper part of the centrifugal filter barrel 501, and the two ends of the elastic telescopic rods 503 are respectively fixedly installed on the centrifugal filter barrel 501 and the frame 10; the plurality of elastic telescopic rods 503 are arranged circumferentially around the axis of the collection barrel 502; thus, the centrifugal filter barrel 501 is elastically mounted on the frame 10. The elastic telescopic rods 503 are prior art and will not be described in detail here.

[0039] In some embodiments, an elastic telescopic component is fixedly installed at the bottom of the centrifugal filter 501. The elastic telescopic component extends through the bottom of the collection tank 502, and the bottom of the elastic telescopic component is rotatably mounted on a bearing seat on the frame 10 via a bearing. In this way, the centrifugal filter 501 is rotatably mounted on the frame 10.

[0040] like Figures 2 to 6 As shown, in some embodiments, the power unit includes a drive shaft 506 rotatably mounted on the frame 10, the drive shaft 506 being mounted at the bottom of the elastic telescopic member, and the power unit also includes a bouncing mechanism that drives the centrifugal filter 501 to bounce up and down when the collection bucket 502 abuts against the inner wall.

[0041] like Figures 2 to 6As shown, in some embodiments, the jumping mechanism includes a mating disc 510 fixedly installed at the bottom of the centrifugal filter tank 501, a transmission disc 507 fixedly installed on the transmission shaft 506, and a drive block 511 installed on the elastic telescopic assembly. The transmission disc 507 is sleeved on the outside of the elastic telescopic assembly, and the drive block 511 moves up and down with the elastic telescopic assembly. A plurality of sliders 508 are provided on the transmission disc 507, and the sliders 508 are arranged elastically along the radial direction of the transmission disc 507. One end of each slider 508 abuts against the drive block. On the side wall of 511; the distance from the top guide of the drive block 511 to the center line of the elastic telescopic component gradually changes; a mating disk 510 is fixedly installed on the slider 508, and a number of arc-shaped grooves 516 are provided at the bottom of the mating disk 510. The number of arc-shaped grooves 516 are arranged in an array along the center of the mating disk 510. A drive rod 509 is fixedly installed on each slider 508. The top of the drive rod 509 abuts against the bottom of the mating disk 510. The arc-shaped grooves 516 are set on the trajectory of the drive rod 509 when the collection bucket 502 is in a low position. Specifically, when the collection bucket 502 is driven by the stirring consumable 301 to press down on the elastic telescopic component, causing the driving block 511 to move down, the top of the driving rod 509 abuts against the mating plate 510, so the centrifugal filter bucket 501 will not move down with the centrifugal filter bucket 501; several sliders 508 are driven to move, causing the driving rod 509 on the slider 508 to move along the trajectory with the arc-shaped groove 516. When the transmission shaft 506 drives the telescopic component to rotate the centrifugal filter bucket 501, it also drives the transmission plate 507 to rotate. The transmission plate 507 drives the slider 508 to rotate, and the slider 508 drives the driving rod 509 to rotate. During the rotation of the driving rod 509, the driving rod 509 passes through several arc-shaped grooves 516, which causes the centrifugal filter bucket 501 to jump up and down under the action of the elastic telescopic rod 503.

[0042] like Figure 3 and Figure 5 As shown, in some embodiments, the bottom of the slider 508 is slidably disposed in a strip groove on the surface of the transmission disk 507. One end of the slider 508 is connected to one end of the second elastic member 515, and the other end of the second elastic member 515 is fixedly mounted on the transmission disk 507, so that the slider 508 is elastically mounted on the transmission disk 507 along the radial direction.

[0043] In some embodiments, the power unit further includes a power component 70, which is mounted on the frame 10. The power component 70 includes a power box and an upper output end of the power box, the output end of which is connected to the drive shaft 506. The power box contains a drive motor and a transmission component. The drive motor is a forward and reverse rotating motor to drive the collection bucket 502 to rotate forward and backward.

[0044] In some embodiments, the elastic telescopic assembly includes a mating sleeve 512 fixedly mounted on a collection tank 502 and a transmission rod 513 elastically slidably mounted on the mating sleeve 512. The bottom of the transmission rod 513 is fixed to a transmission shaft 506. The mating sleeve 512 passes through a through hole at the bottom of the centrifugal filter tank 501, and there is a clearance fit between the mating sleeve 512 and the through hole. The driving block 511 is fixedly mounted on the mating sleeve 512. A first elastic element 514 is provided inside the mating sleeve 512, and the two ends of the first elastic element 514 are respectively fixedly mounted on the transmission rod 513 and the inner wall of the mating sleeve 512. In this way, the transmission rod 513 is elastically slidably mounted on the mating sleeve 512.

[0045] In some embodiments, the distance between the outer side of the drive block 511 and the center line of the mating sleeve 512 is set to gradually increase or decrease from top to bottom.

[0046] In some embodiments, the bottom of the collection bucket 502 is rotatably provided with an abutment plate 504 so that the stirring consumable 301 abuts against the abutment plate 504, thereby reducing the resistance when the collection bucket 502 rotates relative to the stirring consumable 301. The first elastic member 514 and the second elastic member 515 can be helical springs.

[0047] During operation, the raw material liquid and chemical solution to be processed are added to the collection tank 502. Then, the lifting mechanism drives the stirring device 30 and the magnetic attraction device 40 to move downward, so that the stirring consumable 301 is inserted into the collection tank 502, and the bottom of the stirring consumable 301 abuts against the abutment plate 504 on the collection tank 502, causing the collection tank 502 to move downward. The drive rod 509 on the sliding block 508 abuts against the mating plate 510, restricting the downward movement of the centrifugal filter tank 501. The outer side and bottom of the collection tank 502 abut against the corresponding inner wall of the centrifugal filter tank 501. On the bottom wall, this avoids the raw material liquid being inside the centrifugal filter 501, facilitating contact with the stirring device 30; simultaneously, as the mating sleeve 512 moves down with the collection tank 502, the drive slider 508 moves, and when the collection tank 502 abuts against the centrifugal filter 501, the drive rod 509 moves to the trajectory with the arc-shaped groove 516; at this time, the stirring consumable 301 rotates to stir, and during the stirring process, the power component 70 drives the transmission rod 513 and the mating sleeve 512 through the transmission shaft 506 to drive the collection tank 502 to rotate, and as the transmission shaft 506 rotates... During the process, the transmission disc 507 and slider 508 drive the mating disc 510 to rotate together, thereby driving the centrifugal filter 501 to jump up and down. This causes the annular gap formed between the inner wall of the centrifugal filter 501 and the outer wall of the collection tank 502 to periodically contract and expand, thereby generating a pulsating shearing effect on the liquid in the gap, enhancing cell lysis and impurity separation. At the same time, the filter holes on the centrifugal filter 501 are used to divide and impact the raw material liquid, so that it can effectively contact the stirring device 30 and improve the extraction efficiency. After extraction, the lifting mechanism drives the stirring device 30 and the magnetic attraction device 40 to rise, so that the stirring device 30 leaves the centrifugal filter 501. Then the drive rod 509 leaves the track with the arc-shaped groove 516. At this time, the power component 70 drives the collection tank 502 to rotate rapidly through the transmission shaft 506, so that the decomposed liquid is centrifuged and broken down and enters the centrifugal filter 501. A part of the decomposed liquid enters the reaction chamber 60 through the centrifugal filter 501, and then the reaction liquid is added to the reaction chamber 60 to react. After thorough mixing and reaction, the purified liquid is generated to achieve the purification effect.
