Description

Technical Field

[0001] This utility model relates to a sampling device for edible fungi, specifically a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi, belonging to the field of edible fungi sampling technology. Background Technology

[0002] Edible fungi sampling is the process of collecting representative samples from the fruiting bodies, mycelia, and other parts of edible fungi for the detection of nutritional components. It is divided into destructive and minimally invasive methods. In cases where it is necessary to preserve the marketability or growth capacity of edible fungi, rapid on-site testing is required to avoid changes in composition, the sample volume is limited or high-frequency sampling is required in a small area, and efficient comparative testing is needed in breeding screening, minimally invasive sampling devices are used for rapid detection of nutritional elements in edible fungi. These devices can collect small amounts of samples with minimal damage, meet the needs of rapid testing, and balance testing efficiency with the integrity of the fungal cells.

[0003] The existing utility model with authorization announcement number CN221598828U discloses an edible fungus sampling device. A panel is provided on a support base, which is threadedly connected to the inner wall of the shell. A culture dish for culturing edible fungi is placed on the panel, allowing several different types of edible fungi to be cultured in the dish. The shell contains a transverse moving mechanism, a longitudinal moving mechanism, and a sampling mechanism. The transverse moving mechanism moves the panel out of or into the shell. The longitudinal moving mechanism is connected to an extraction mechanism, which is used to sample the edible fungi. The longitudinal moving mechanism drives the sampling mechanism to move longitudinally, allowing the extraction mechanism to contact the edible fungi and complete the sampling. This device integrates edible fungus sampling and cultivation, facilitating sampling and analysis of edible fungi at different stages of growth. During the growth process, the device can automatically sample the edible fungi at preset intervals for analysis, determining the components of different edible fungi at different cultivation times and thus identifying the optimal cultivation time for each fungi. This eliminates the need for manual sampling each time, making operation convenient and meeting user needs.

[0004] While the aforementioned technical solutions enable sampling of edible fungi at different stages within a petri dish, they require the fungi to be moved below the sampling structure before sampling can be performed. This lack of a convenient and efficient sampling structure hinders flexible sampling of fungi cultivated in different locations, resulting in poor overall usability. Therefore, this paper proposes a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi. Utility Model Content

[0005] This invention proposes a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi, in order to solve the problem that the existing technology lacks a rapid sampling structure that can improve the convenience of sampling, which makes it inconvenient to flexibly sample edible fungi cultivated in different locations, resulting in poor usability of the entire sampling structure.

[0006] This utility model is achieved through the following technical solution: a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi, including a sampling needle, and a quick sampling mechanism is provided above the sampling needle;

[0007] The quick sampling mechanism includes a movable frame, a fixed block above the movable frame, two limiting guide rods fixedly connected to the upper surface of the movable frame, a limiting top post fixedly connected to the bottom surface of the fixed block, a limiting disc fixedly connected to the top of each limiting guide rod, a return spring sleeved on the outer surface of each limiting guide rod, and a top cone fixedly connected to the bottom end of the limiting top post.

[0008] Specifically, the inner wall of the movable frame is fixedly connected to the outer surface of the sampling needle, the outer surface of each limiting guide rod is slidably connected to the inside of the fixed block, the outer surface of the limiting top column is slidably connected to the inside of the movable frame, the two ends of each return spring are fixedly connected to the upper surface of the movable frame and the bottom surface of the fixed block, respectively, the outer surface of the top cone is slidably connected to the inside of the sampling needle, a support rod is fixedly connected to the front of the movable frame, and a rotating column is rotatably connected to the outer surface of the support rod.

[0009] Furthermore, a handle is fixedly connected to the upper surface of the fixing block, and an anti-slip sleeve is fixedly connected to the outer surface of the handle.

[0010] The fixed block has a support fixedly connected to its back side, and a tie rod is fixedly connected to the inner wall of the support.

[0011] Preferably, the support is provided with a handle inside, and the inner wall of the handle is rotatably connected to the outer surface of the pull rod.

[0012] Furthermore, each of the limiting discs has a buffer washer fixedly connected to its bottom surface, the inner wall of each buffer washer is in contact with the outer surface of the limiting guide rod, and the bottom surface of each buffer washer is in contact with the upper surface of the fixing block.

[0013] This invention provides a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi, which has the following beneficial effects:

[0014] This minimally invasive sampling device for rapid detection of nutrient elements in edible fungi utilizes the coordinated operation of a sampling needle, a movable frame, a fixed block, a limiting top column, a limiting guide rod, a limiting plate, a return spring, and a top cone. The sampling needle slides upwards along the outer surface of the limiting top column with the movable frame, while the limiting guide rod slides up and down along the inside of the fixed block. During this process, two return springs are gradually compressed. Then, by aligning the bottom of the sampling needle with the appropriate location on the edible fungus to be sampled, pinching the fixed block, and suddenly releasing the movable frame, the bottom of the sampling needle quickly pierces the edible fungus, leaving a small sample. Furthermore, by pressing the movable frame towards the fixed block, the top cone can eject the sample from the sampling needle, allowing for repeated use and achieving rapid sampling. This enhances the overall ease of use of the sampling device, avoiding the problem of limited convenience caused by the lack of a rapid sampling structure that hinders flexible sampling of edible fungi cultivated in different locations.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-4 This utility model provides a minimally invasive sampling device for rapid detection of nutrient elements in edible fungi, including a sampling needle 1. The sampling needle 1 has an existing structure with a spike at the bottom, which can retain the flesh of the edible fungi inside after insertion. The specific size can be selected according to the actual use scenario. A quick sampling mechanism 2 is provided above the sampling needle 1. The quick sampling mechanism 2 includes a movable frame 201. A fixed block 202 is provided above the movable frame 201. The inner wall of the movable frame 201 is fixedly connected to the outer surface of the sampling needle 1. A support rod 5 is fixedly connected to the front of the movable frame 201. A rotating column 6 is rotatably connected to the outer surface of the support rod 5. By setting the support rod 5, a rotation base surface can be provided for the rotating column 6, so that after the finger holds the rotating column 6, it is easy to quickly release the rotating column 6. In combination with other rebound structures, it can provide sufficient piercing force to the sampling needle 1 and improve sampling efficiency.

[0025] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 Two limiting guide rods 204 are fixedly connected to the upper surface of the movable frame 201. The outer surface of each limiting guide rod 204 is slidably connected to the inside of the fixed block 202. A limiting top post 203 is fixedly connected to the bottom surface of the fixed block 202. The outer surface of the limiting top post 203 is slidably connected to the inside of the movable frame 201. A handle 3 is fixedly connected to the upper surface of the fixed block 202. An anti-slip sleeve 4 is fixedly connected to the outer surface of the handle 3. By setting the handle 3, it is convenient to hold the entire sampling device with one hand and stabilize it. By setting the anti-slip sleeve 4, the anti-slip property of the outer surface of the handle 3 can be increased.

[0026] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 Each limiting guide rod 204 has a limiting plate 205 fixedly connected to its top end. A support 7 is fixedly connected to the back of the fixing block 202. A pull rod 8 is fixedly connected to the inner wall of the support 7. By setting the pull rod 8, a rotation base surface can be provided for the suspension structure inside the support 7. By setting the support 7 and the pull rod 8, they can work together with the above-mentioned suspension structure to suspend the entire sampling device when it is placed, which facilitates the storage of the entire sampling device and thus protects the sampling needle 1 to a certain extent.

[0027] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3Each limiting guide rod 204 has a return spring 206 fitted on its outer surface. The two ends of each return spring 206 are fixedly connected to the upper surface of the movable frame 201 and the bottom surface of the fixed block 202, respectively. The support 7 has a handle 9 inside. The inner wall of the handle 9 is rotatably connected to the outer surface of the pull rod 8. By setting the handle 9, it can rotate around the outer surface of the pull rod 8 inside the support 7. Thus, the handle 9 can be suspended on a certain structure to facilitate the storage of the entire sampling device, thereby protecting the sampling needle 1 to a certain extent.

[0028] Please refer to this carefully. Figure 2 and Figure 4 The bottom end of the limiting top post 203 is fixedly connected to the ejector cone 207. The ejector cone 207 is a solid structure and is mainly used to eject the sample from the sampling needle 1, so as to facilitate the quick and repeated use of the sampling needle 1. The outer surface of the ejector cone 207 is slidably connected to the inside of the sampling needle 1. The bottom surface of each limiting plate 205 is fixedly connected to the buffer washer 10. The inner wall of each buffer washer 10 is in contact with the outer surface of the limiting guide rod 204, and the bottom surface of each buffer washer 10 is in contact with the upper surface of the fixing block 202. By setting the buffer washer 10, a good buffering effect is achieved. It can be placed between the fixing block 202 and the limiting plate 205 to prevent the limiting plate 205 from colliding with the fixing block 202 too much during the movement.

[0029] When using this utility model: First, hold the handle 3, keep your palm in contact with the anti-slip sleeve 4 for stability, and hook the rotating column 6 with your finger joints and pull it upward. At this time, the movable frame 201 moves upward synchronously with the rotating column 6 and the support rod 5, and slides along the outer surface of the limiting top column 203. At the same time, the limiting guide rod 204 slides along the inside of the fixed block 202. The return spring 206 is squeezed and contracted by the movable frame 201 and the fixed block 202, gradually storing elastic potential energy. The limiting plate 205 moves upward with the limiting guide rod 204.

[0030] Next, after aligning the bottom of the sampling needle 1 with the sampling site of the edible fungus, release the rotating column 6. The return spring 206 releases potential energy, pushing the movable frame 201 to move down quickly, causing the sampling needle 1 to pierce the edible fungus. During the piercing process of the sampling needle 1, the limiting guide rod 204 slides down along the fixed block 202, and the limiting plate 205 limits the downward movement of the movable frame 201. The edible fungus tissue debris is withdrawn with the sampling needle 1 and remains inside the needle, thus completing the sampling.

[0031] After sampling, the movable frame 201 is pressed again towards the fixed block 202, and the top cone 207 at the bottom of the limiting top column 203 moves upward and slides along the inside of the sampling needle 1, pushing the sample inside the needle into a suitable external sample storage structure. After the operation is completed, the device can be suspended at the support 7 by rotating the handle 9 around the pull rod 8 to avoid damage to the sampling needle 1 for future use. The design of the entire minimally invasive sampling device for rapid detection of edible fungi nutrients effectively solves the problem that the lack of a quick sampling structure that can improve the convenience of sampling makes it inconvenient to flexibly sample edible fungi cultivated in different locations, resulting in poor usability of the entire sampling structure.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
