Abstract
Description
Technical Field

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The purpose of this invention is to provide a tool for enriching selenium in edible fungi, so as to solve the problems existing in the above-mentioned related technologies and accurately control the amount of selenium solution added at one time.
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Reference Figure 1 , Figure 2 This embodiment provides a selenium-enriched tool for edible fungi, including an injection piston 4, an injection cylinder 10, a needle 2, and a gear 7.
[0031] The injection piston 4 includes a push rod and a piston body 5, with the piston body 5 fixed to one end of the push rod. The injection cylinder 10 has a bottom and an opening. A needle mounting hole 12 is provided at the bottom. The piston body 5 slides against the inner wall of the injection cylinder 10 to form a collection chamber 11 for containing selenium solution between the piston and the bottom. Volume markings 8 are provided on the side wall of the injection cylinder 10. At least the area containing the volume markings 8 is made of transparent material. The needle 2 is fixed to the needle mounting hole 12, allowing the selenium solution to enter and exit the collection chamber 11 through the needle 2. A gear 7 is rotatably mounted on the side wall of the injection cylinder 10. A window is provided on the side wall of the injection cylinder 10, through which the gear 7 passes. A rack 6 is provided along the length of the push rod, and the gear 7 meshes with the rack 6.
[0032] Among them, one end face of the piston body 5 is an indicator end face, and the value of the volume scale 8 corresponding to the indicator end face is equal to the volume of the liquid accumulation chamber 11 corresponding to the position of the injection piston 4.
[0033] The indicating end face of the piston body 5 can be the end face near the bottom of the cylinder, in which case the volume scale 8 corresponding to the position of the bottom of the cylinder is zero; the indicating end face of the piston body 5 can also be the end face away from the bottom of the cylinder, in which case the distance between the position where the volume scale 8 is zero and the bottom of the cylinder is the length of the piston body 5.
[0034] The working principle of the selenium-enriched tool for edible fungi in this embodiment is as follows:
[0035] First, push the injection piston 4 to the bottom of the injection cylinder 10, so that the piston body 5 abuts against the bottom of the cylinder. At this time, the volume scale 8 corresponding to the indicator end face is zero. Then, immerse the needle 2 into the selenium solution. Next, rotate the gear 7, causing the injection piston 4 to slowly slide away from the needle 2, gradually increasing the volume of the effusion chamber 11, drawing the selenium solution into the effusion chamber 11. When the volume scale 8 corresponding to the indicator end face equals the preset single injection volume, stop rotating the gear 7, place the needle 2 above the culture medium, and slide the piston body 5 towards the bottom of the cylinder until it contacts the bottom by rotating the gear 7 or pushing the injection piston 4. The selenium solution in the effusion chamber 11 is then completely applied to the culture medium, completing the single application. Repeat the above steps until the total amount of selenium solution applied to the culture medium reaches the preset value.
[0036] In this embodiment, the sliding control of the injection piston 4 is transformed into the rotation control of the gear 7. The user only needs to hold the syringe 10 and press the gear 7 with his thumb to easily position the circumferential position of the gear 7, thereby accurately controlling the amount of selenium solution in the fluid accumulation chamber 11, which is simple and convenient.
[0037] In some examples, the selenium-enriched edible fungi tool also includes a baffle 1 and a spring 3. The baffle 1 is detachably fixed to the opening of the syringe, and the push rod passes through the baffle 1. The spring 3 is located inside the syringe 10, and its two ends abut against the injection piston 4 and the baffle 1, respectively.
[0038] Spring 3 is used to increase the rotational resistance of gear 7. As the volume of the liquid accumulation chamber 11 increases, the compression of spring 3 gradually increases, and the rotational resistance of gear 7 gradually increases. This increases the resistance, thereby reducing the sliding speed of injection piston 4. When piston body 5 stops sliding, its indicating end face can accurately stop at the preset volume scale 8 corresponding to a single injection volume. Furthermore, due to the spring 3, after gear 7 stops rotating, only one-sided force needs to be applied to gear 7 to maintain its position, making it easier to operate.
[0039] Figure 1 In the middle, the left side of the syringe 10 is the volume scale 8, and the right side is the gear 7. At least the area where the volume scale 8 is located is made of transparent material.
[0040] In some examples, the baffle 1, push rod, and syringe 10 are arranged concentrically, and the diameter of the baffle 1 is larger than the diameter of the syringe 10.
[0041] The baffle 1 not only provides the contact position of the spring 3 and the sliding guide for the push rod, but also, because its diameter is larger than that of the syringe 10, its outer flange is easy for the user to grip, so that the syringe 10 can be kept in the hand better when rotating the gear 7.
[0042] In some examples, the push rod includes a large-diameter section, a small-diameter section, and a handle 9 connected sequentially along its length. A rack 6 is located on the large-diameter section. A spring 3 is fitted onto the outside of the small-diameter section and abuts against the end face of the large-diameter section. The handle 9 is located on the outside of the syringe 10.
[0043] Since spring 3 is sleeved on the outside of the small-diameter section, it can be straightened by the push rod, thus playing a positioning role and preventing spring 3 from tilting. By making the diameter of the large-diameter section larger than that of the small-diameter section, the end of spring 3 near the piston body 5 does not need to abut against the piston body 5, but only against the end face of the large-diameter section, thereby shortening the length of spring 3, reducing the overall weight and production cost.
[0044] In some examples, the needle 2 includes a needle bar 14 and a mounting base 13, with the needle bar 14 fixedly connected to the mounting base 13 and the mounting base 13 fixedly connected to the needle mounting hole 12.
[0045] The mounting base 13 has a larger diameter than the needle bar 14, making it easier to grip and install the needle 2 at the bottom of the syringe. When the needle bar 14 needs to be replaced, only the needle 2 needs to be replaced as a whole, that is, the needle bar 14 and the mounting base 13 are removed and replaced together, making the operation more convenient.
[0046] In some examples, the mounting base 13 has a central through hole, one end of the needle bar 14 is inserted into the central through hole and is interference-fitted with the central through hole.
[0047] After leaving the factory, the needle shaft 14 of this edible fungus selenium-enriching tool is pre-installed in the central through hole of the mounting base 13. The needle head 2 is separate from the bottom of the cylinder, and the user needs to install the needle head 2 on the bottom of the cylinder himself. By separating the needle head 2 from the bottom of the cylinder, the overall length of the edible fungus selenium-enriching tool can be reduced, thereby reducing the packaging volume.
[0048] In some examples, the mounting base 13 is threaded into the needle mounting hole 12.
[0049] The threaded connection method facilitates installation and disassembly while providing a certain locking force to prevent the needle 2 from flying out under the pressure provided by the selenium solution.
[0050] In some examples, the needle bar 14 is a hollow structure and has multiple side holes on its sidewalls, which are evenly distributed along the axial direction of the needle bar 14.
[0051] The pores of the multiple side holes are approximately the same size, which allows the selenium solution to flow out evenly from multiple equally spaced locations, making the distribution of the selenium solution in the culture medium more uniform.
[0052] In some examples, the end of the needle bar 14 facing away from the mounting base 13 has an oblique section.
[0053] The inclined section is preferably closed, meaning the selenium solution flows out only from the side hole of the needle shank 14. It should be noted that the flow area of the inclined section is generally larger than the flow area of the side hole; by closing it, the outflow of dilute solution at the location of the inclined section is prevented from being significantly greater than at other locations. The sharp angle provided by the inclined section can be used to puncture structures such as packaging bags for ease of operation.
[0054] In some examples, the outer side of the mounting base 13 is provided with an annular protrusion.
[0055] The annular protrusion provides an area that is easy for the user to grip, thus facilitating operations such as rotating the mounting base 13.
[0056] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
