Description

Technical Field

[0001] This utility model relates to the field of sample extraction and soaking technology, specifically to a sample extraction and soaking device. Background Technology

[0002] As is well known, immersion extraction is a common method for sample extraction. Immersion extraction is used to extract a substance from a sample. The extractant used should be able to dissolve the substance in large quantities without damaging its properties. Therefore, in sample extraction, the sample needs to be soaked to extract the desired substance, facilitating successful detection.

[0003] Currently, sample extraction involves using a sample picker to pick up the sample, which is then inserted into an immersion container. The sample and extractant undergo a biochemical reaction, and after a specified time, the desired substances are extracted from the immersion container. The sample test results are obtained by analyzing the mixed solution. However, the sample picker and immersion container are designed as separate units, which is inconvenient to operate. After use, waste disposal is required, which can easily lead to omissions. Furthermore, the sample picker is frequently exposed to the outside environment after use, which can easily cause contamination. Utility Model Content

[0004] The purpose of this invention is to provide a sample extraction and soaking device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample extraction and soaking device, comprising: An immersion container, the top of which is provided with a sealing layer, and the interior of which contains an extract; The sampling component includes a sliding rod and a sample dipping component. The sample dipping component is installed at one end of the sliding rod. The sliding rod is slidably inserted into the soaking container. The sampling component is provided with multiple fragments on its exterior, and the fragments are radially distributed with the central axis of the sliding rod as the center. The positioning element is used to fix the sampling element.

[0006] Preferably, the positioning element includes a base, a bracket, and an insertion port. The base is fixedly installed on the top of the soaking container, the bracket is installed on the base, the insertion port is opened on the bracket, and one end of the broken piece is embedded in the insertion port.

[0007] Preferably, the bracket is shaped like an inclined "L", and the bracket and the base are an integrated structure.

[0008] Preferably, it also includes a limiting block, which is installed outside the sliding rod and abuts against the lower end of the soaking container when the broken piece is embedded in the insertion port.

[0009] Preferably, the sample extraction and soaking device further includes a vibrating element, which includes an annular ring and a protrusion. The annular ring is installed inside the soaking container, and the protrusion is disposed on the annular ring.

[0010] Preferably, the protrusions are shaped like arcs, and one end of the fragment extends between the two protrusions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This sample extraction and soaking device: the sample is dipped in the sample pick-up piece, and the sliding rod is pulled down so that the cutting blade cuts the sealing layer, allowing the sample pick-up piece to be smoothly immersed in the soaking container. The sample pick-up piece and the soaking container are designed as an integrated unit. After soaking, the sample pick-up piece is still retracted into the soaking container. By reducing the contact between the sample pick-up piece and the outside, the occurrence of contamination is reduced. In addition, during use, the sliding rod can be rotated to drive the cutting blade to tap the protrusion, which can generate a certain vibration, which is more conducive to the mixing of sample and extractant.

[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0015] See Figure 1-4 This utility model provides a technical solution: a sample extraction and soaking device, comprising: A soaking container 10, the top of which is provided with a sealing layer 14, and the interior of the soaking container 10 contains an extract; The sampling component includes a sliding rod 11 and a sample scooping component 12. The sample scooping component 12 is installed at one end of the sliding rod 11. The sliding rod 11 is slidably inserted into the immersion container 10. Multiple fragments 13 are provided on the outside of the sampling component, and the fragments 13 are radially distributed around the central axis of the sliding rod 11. The sliding rod 11 is inserted into the immersion container 10 and is slidably connected to the sealing layer 14. A sealing ring is provided between the sliding rod 11 and the sealing layer 14 to prevent the extract from flowing out of the immersion container 10 and to ensure that the extract is contained in the immersion container 10. After the sample scooping component 12 has taken a sample, the sliding rod 11 can be moved downward by pulling the sample scooping component 12, which will cause the fragments 13 to come into contact with the sealing layer 14 and break the sealing layer 14, so as to ensure that the sample scooping component 12 can be smoothly immersed in the immersion container 10. The positioning element is used to fix the sampling element. When the sample pick-up piece 12 is immersed in the soaking container 10, the positioning element can position the sampling element to ensure that the sampling element is relatively stationary when not in use, thus ensuring stability.

[0016] The positioning component includes a base 17, a bracket 15, and an insertion port 16. The base 17 is fixedly installed on the top of the soaking container 10, the bracket 15 is installed on the base 17, and the insertion port 16 is formed on the bracket 15. One end of the fragment 13 is embedded in the insertion port 16. In use, by rotating the sliding rod 11, the sliding rod 11 drives the fragment 13 to rotate, which causes the bracket 15 to bend downward under the pressure of the fragment 13. This allows the fragment 13 to disengage from the insertion port 16, thus allowing the sliding rod 11 to be pulled downward smoothly.

[0017] The bracket 15 is shaped like an inclined "L", and the bracket 15 and the base 17 are an integrated structure. The "L" shape of the bracket 15 ensures that the bracket 15 has good deformability, and ensures that the fragment 13 can be easily disengaged from the insertion port 16. It also includes a limiting block 101, which is installed outside the sliding rod 11. When the broken piece 13 is embedded in the insertion port 16, the limiting block 101 abuts against the lower end of the soaking container 10. (See attached image) Figure 1 In the middle, the setting of the limiting block 101 can limit the extension of the sliding rod 11, prevent the sliding rod 11 from moving upward and causing the broken piece 13 to fall out of the insertion port 16, and improve stability.

[0018] The sample extraction and immersion device also includes a vibrating element, which comprises an annular ring 18 and protrusions 19. The annular ring 18 is installed inside the immersion container 10, and the protrusions 19 are disposed on the annular ring 18. The protrusions 19 are arc-shaped, and one end of the fragment 13 extends between the two protrusions 19. After the sample pick-up piece 12 is immersed in the immersion container 10, the sliding rod 11 can be rotated, causing the fragment 13 to rotate. One end of the fragment 13 extends between the two protrusions 19, so the fragment 13 will bend during rotation. After the fragment 13 detaches from the protrusion 19, it will rebound and impact the next protrusion 19, thus generating vibration, which further facilitates the mixing of the sample and the extractant.

[0019] In use, firstly, the sample pick-up piece 12 is used to pick up the sample. Then, by rotating the sliding rod 11, the sliding rod 11 drives the fragment 13 to rotate, which causes the support 15 to bend downward under the pressure of the fragment 13. This allows the fragment 13 to disengage from the insertion port 16. Then, by pulling the sliding rod 11 downward, the sliding rod 11 moves downward, causing the fragment 13 to come into contact with the sealing layer 14, causing the sealing layer 14 to break. As it continues to descend, it ensures that the sample pick-up piece 12 can be smoothly immersed in the soaking container 10. After reaching the bottom, the sliding rod 11 needs to be rotated again, which will drive the fragment 13 to rotate. One end of the fragment 13 extends between the two protrusions 19. In this way, the fragment 13 will bend during rotation. After the fragment 13 disengages from the protrusion 19, it will rebound and impact the next protrusion 19, thus creating vibration, which is more conducive to the mixing of the sample and the extractant.
