Description

Technical Field

[0001] This utility model relates to the field of biological disinfection technology, and in particular to a seed sterilization device. Background Technology

[0002] In plant research, seeds typically need to be sterilized before experiments to eliminate surface pathogens and ensure experimental reliability. Common sterilization methods include mercuric chloride sterilization and sodium hypochlorite liquid sterilization. Sodium hypochlorite liquid sterilization is widely used due to its good sterilization effect and relatively simple operation.

[0003] Traditional chlorine generators typically have the following drawbacks:

[0004] In terms of safety, chlorine gas is prone to leakage from containers when it is generated instantly. It is highly irritating and toxic, directly endangering the health of laboratory personnel, and the laboratory environment is easily contaminated.

[0005] Regarding sterilization effectiveness: Open or semi-open environments make it difficult to maintain chlorine concentration, which is easily diffused and lost, affecting the uniform and sufficient action on seeds and potentially leading to incomplete sterilization.

[0006] In terms of operational controllability: the rate and amount of hydrochloric acid addition are difficult to control precisely, which can easily lead to an overly violent reaction, producing a large amount of foam or even splashing, increasing the risk.

[0007] Inconvenient cleaning and poor flexibility: Reaction residues (such as salt crystals) adhere to the inner wall of the fixed container, making cleaning difficult; at the same time, the fixed container structure is difficult to flexibly adapt to different seed quantities or sterilization dosage requirements.

[0008] Therefore, there is an urgent need to design a dedicated laboratory seed sterilization device that is safe to operate, highly efficient in sterilization, has controllable dosage, and is easy to clean and maintain. Utility Model Content

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1 to 5 As shown, this embodiment provides a seed sterilization device, including a box body 1, a reaction box 2, a cover 3, and a syringe. The box body 1 has a receiving cavity for holding seeds. The reaction box 2 is used to hold a first reaction liquid, and is placed inside the receiving cavity, spaced apart from the seeds. The cover 3 covers the opening of the box body 1, and has an injection hole 33 corresponding to the reaction box 2. A self-sealing elastic element is provided inside the injection hole 33. The syringe can pass through the elastic element to inject a second reaction liquid into the reaction box 2.

[0039] Specifically, in this embodiment, the first reaction liquid is a sodium hypochlorite solution, and the second reaction liquid is hydrochloric acid. It should be noted that the box 1, reaction box 2, and cover 3 are all made of corrosion-resistant materials. Figure 3 and Figure 4 As shown, a groove is provided inside the injection hole 33, and a circumferentially convex ring is provided on the self-sealing elastic element. The elastic element is locked in the groove by the convex ring, which facilitates replacement after long-term use. When using this seed sterilization device, first open the cover 3, put the reaction box 2 containing sodium hypochlorite solution and the seeds into the receiving cavity, then seal the cover 3 and the box 1. Inject hydrochloric acid into the reaction box 2 through the injection hole 33 on the cover 3 with a syringe. The hydrochloric acid reacts with the sodium hypochlorite solution in a closed environment to produce chlorine gas, which can fumigate and sterilize the seeds in the receiving cavity.

[0040] It is understandable that the seed sterilization device provided by this utility model can effectively prevent the leakage of sterilizing gas, protect the health of experimental personnel, and is conducive to the stability of sterilizing gas concentration, thorough sterilization, and ensuring sterilization effect. At the same time, after the experiment is completed, the reaction box 2 can be taken out after opening the cover 3 for easy cleaning.

[0041] In one embodiment, the accommodating cavity is divided into a reaction zone 11 and a sample zone 12 along a first direction. The reaction zone 11 is used to place the reaction box 2, and the sample zone 12 is used to place the seeds.

[0042] Specifically, such as Figure 5As shown, in this embodiment, approximately one-third of the volume inside the box 1 is the reaction zone 11, and the reaction box 2 is placed within the reaction zone 11. The remaining portion inside the box 1 is the sample zone 12. It is understood that this division allows the chlorine gas generated by the reaction to rapidly diffuse into the large seed space, where it is immediately diluted. This avoids the formation of a "high-concentration chlorine cloud" near the solution, preventing the seeds adjacent to the solution from being "burned" or poisoned. An effective but relatively mild sterilization concentration can be achieved throughout the entire containment chamber, effectively sterilizing while maximizing the protection of seed viability. Furthermore, when chlorine gas is released from the sealed containment chamber, the pressure inside the chamber does not rise sharply, reducing the risk of leakage from the seed sterilization device due to excessive pressure.

[0043] Furthermore, in some embodiments, along the second direction, a plurality of reaction boxes 2 are provided inside the box body 1, and a plurality of injection holes 33 are provided on the cover body 3 corresponding to the plurality of reaction boxes 2, and the second direction is perpendicular to the first direction.

[0044] Specifically, such as Figure 1 As shown, in this embodiment, three reaction boxes 2 are arranged inside the box body 1 along the second direction, and injection holes 33 are opened on the cover body 3 at the positions corresponding to the three reaction boxes 2. It can be understood that by setting three reaction boxes 2, different doses of sodium hypochlorite solution can be placed in the three reaction boxes 2 respectively, which can flexibly adapt to the needs of different sterilization dosages.

[0045] Furthermore, to ensure a proper seal between the lid 3 and the box 1, in some embodiments, a sealing ring is provided between the lid 3 and the box 1. It is understood that the sealing ring can be provided on the lid 3 or on the box 1, or even on both the lid 3 and the box 1.

[0046] More specifically, in this embodiment, a fixing groove 31 is provided circumferentially on the lower surface of the cover 3, and a sealing ring is disposed in the fixing groove 31 and can abut against the upper surface of the box 1. The sealing ring is a rubber sealing ring. When the cover 3 is placed on the opening of the box 1, the sealing ring can be pressed against the box 1 by the cover 3, thereby making the cavity a sealed space, which can effectively ensure airtightness, maintain an effective chlorine concentration, and protect the safety of operators and the environment.

[0047] In some other embodiments, the cover 3 is rotatable relative to the box 1. It is understood that one end of the cover 3 is hinged to the box 1, and when it is necessary to open the cover 3, it can be opened by rotating the cover 3. After the seeds and reaction box 2 are taken out, it is convenient to put the cover 3 back on the box 1.

[0048] Furthermore, in order to facilitate opening the receiving cavity, in some embodiments, the cover 3 is provided with a handle 32.

[0049] Specifically, in this embodiment, the cover 3 is placed on the box 1, and the handle 32 is set in the middle of the upper surface of the cover 3. The cover 3 is opened and closed very smoothly, reducing the operating burden of the experimenter and facilitating one-handed operation.

[0050] Furthermore, in some embodiments, at least one of the cover 3 and the box 1 is a transparent or semi-transparent component.

[0051] Understandably, by using transparent or semi-transparent parts for at least one of the lid 3 and the box 1, the sterilization process can be visualized, greatly improving the convenience, safety and monitorability of operation, and reducing the risks and errors caused by blind operation.

[0052] Furthermore, in some embodiments, the box body 1 is provided with a placement rack and a positioning groove 111, the seeds are placed on the placement rack, and the reaction box 2 is placed in the positioning groove 111.

[0053] Specifically, in this embodiment, the reaction zone 11 of the box 1 is provided with three positioning slots 111. The placement rack is an EP tube rack. The reaction box 2 is interference-fitted with the positioning slots 111, allowing the reaction box 2 to be stably placed within the positioning slots 111 and easily removed when needed. The placement area inside the box 1 is provided with a placement rack, which allows the chlorine gas generated by the reaction to sterilize the seeds placed on the rack from multiple angles, thus ensuring the sterilization effect.

[0054] Furthermore, in some embodiments, the injection speed of the syringe can be linearly adjusted. It is understood that by selecting a linearly adjustable syringe, the manual control of adding the second reaction solution can be transformed into a precisely quantifiable, highly repeatable, safe, and controllable operation, greatly improving the safety and success rate of the experiment, while also enhancing the accuracy of the experimental results.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
