Description

Technical Field

[0001] This utility model relates to the field of seed cultivation device technology, specifically a novel sterile seed germination device. Background Technology

[0002] Seed germination devices are key equipment in modern agricultural planting and laboratory research. Their main function is to provide seeds with optimal environmental conditions such as temperature, humidity, and light, breaking seed dormancy and promoting rapid and uniform germination. This forms the basis for industrialized seedling production, variety selection, and scientific experiments. The uniformity and success rate of seed germination directly affect the subsequent growth vigor of seedlings and the final yield. However, in sterile germination environments with stringent cleanliness requirements, many existing seed germination devices still have significant shortcomings in maintaining humidity stability and ease of operation.

[0003] First, many existing germination devices lack automatic and precise water replenishment mechanisms. The moisture in the culture chamber gradually decreases due to natural evaporation and seed absorption, leading to a drop in humidity. Maintaining stable humidity usually requires frequent manual observation and water replenishment. This not only increases the operational burden but can also cause drastic fluctuations in humidity due to untimely or excessive water replenishment. This can result in either dry filter paper affecting seed imbibition and germination, or localized over-hydration leading to mold growth, both of which negatively impact the uniformity and success rate of seed germination.

[0004] Secondly, many existing germination devices have poorly sealed chamber lids or rudimentary locking mechanisms. Some rely solely on simple latches or weight for closure, making them prone to accidental opening due to impacts or changes in internal pressure. This not only leads to rapid evaporation of moisture inside the culture chamber, making it difficult to maintain humidity, but more seriously, it can disrupt the sterile environment and increase the risk of external contaminants entering. Furthermore, rudimentary locking designs may cause the lid to detach and spill cultures when handling or moving equipment, resulting in poor safety. Additionally, opening and closing operations are often inconvenient. Utility Model Content

[0007] As a further embodiment of this utility model: the sealing assembly includes a mounting groove and a sealing ring, the mounting groove being formed inside the compartment cover, and the sealing ring being fixedly installed inside the mounting groove.

[0008] As a further embodiment of this utility model: the water replenishment component includes a lifting frame, a baffle, a pipe, a water storage tank and a water inlet.

[0010] As a further embodiment of this utility model: the fixing assembly includes two upper insert plates, two slots, two sliding frames, two lower insert plates, and two springs. Each upper insert plate is fixedly installed at the bottom of the chamber cover. The two slots are respectively opened on the outer walls of the two upper insert plates. Each sliding frame is fixedly installed on the outer wall of the culture chamber. The two lower insert plates are slidably connected to the inside of the two sliding frames.

[0013] As a further embodiment of this invention, the outer wall of the culture chamber is provided with scale values.

[0014] As a further embodiment of this utility model, the surface of the water tank cover is provided with anti-slip grooves.

[0015] The beneficial effects of this utility model are as follows: 1. The water storage mechanism of this device implements a highly efficient and adaptive automatic water replenishment system. It uses a float and connecting rod in the drive assembly as the core water level sensing unit. When the sterile water stored in the lower layer of the culture chamber decreases due to evaporation and absorption by the seeds, the drop in water level causes the float to descend synchronously. The float, via the connecting rod, pulls a baffle down within the lifting frame, automatically opening the water inlet. At this time, sterile water stored in the external water tank flows into the lower layer of the culture chamber under gravity through the pipes to replenish the water. As the water level gradually rises, the float rises and pushes the baffle up via the connecting rod, ultimately closing the water inlet again, achieving automatic start and stop of the water replenishment process. This mechanical feedback control based on the principle of buoyancy requires no electrical intervention, intelligently maintaining a stable water level in the culture chamber, ensuring continuous moisture in the filter paper, providing a constant humidity environment for seed germination, and significantly reducing the frequency and operational burden of manual water replenishment.

[0016] 2. The locking mechanism of this device is ingeniously designed, combining reliability, safety, and convenience. Its core lies in the fixing component, which utilizes a mechanical interlocking principle to securely fix the chamber lid. When the lid is closed, the upper insert plate at the bottom of the lid, with its inclined structure, presses against the lower insert plate on the outer wall of the culture chamber, causing it to retract into the sliding frame against the spring force. When the slot on the upper insert plate moves to the position aligned with the lower insert plate, the elastic potential energy of the spring is released instantaneously, pushing the lower insert plate to quickly pop out and precisely engage with the slot, thus completing the locking process. This process is automatic and rapid, effectively avoiding the risk of moisture loss and disruption of the sterile environment due to accidental opening of the lid or poor sealing. Especially when removing the device, even if the lid is accidentally lifted, it ensures that the culture chamber will not fall off, improving safety. Furthermore, the locking can be easily manually released via the pull plate of the auxiliary component, facilitating opening the lid for operation and maintenance, balancing sealing reliability and ease of use.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-6 As shown, this embodiment provides a novel sterile seed germination device, including a culture chamber 1, a chamber cover 2, a culture mechanism, a water storage mechanism, and a locking mechanism. The chamber cover 2 is slidably connected to the top of the culture chamber 1. The culture mechanism is located inside the culture chamber 1. The culture mechanism includes a separating component and a sealing component. The separating component is located inside the culture chamber 1, and the sealing component is located inside the chamber cover 2. The water storage mechanism is located inside the culture chamber 1. The water storage mechanism includes a water replenishment component and a drive component. The water replenishment component is located inside the culture chamber 1, and the drive component is located on the water replenishment component. The locking mechanism is located on the outer wall of the culture chamber 1. The locking mechanism includes a fixing component and an auxiliary component. The fixing component is located on the outer wall of the culture chamber 1, and the auxiliary component is located on the fixing component.

[0028] like Figures 1-2 As shown, the partition assembly includes a partition platform 3, a mesh plate 4, two card holders 5, and two connecting slots 6. The partition platform 3 is fixedly installed inside the culture chamber 1, and the mesh plate 4 is slidably connected inside the culture chamber 1. Each card holder 5 is fixedly installed on the top of the partition platform 3, and each connecting slot 6 is opened on the top of the mesh plate 4. The two card holders 5 are slidably connected to the inside of the two connecting slots 6 respectively. The partition platform 3 allows the mesh plate 4 to be placed inside the culture chamber 1, dividing the culture chamber 1 into two layers. The card holder 5 is inserted through the large opening of the connecting slot 6, and then rotated to allow the card holder 5 to enter the small opening of the connecting slot 6, thereby firmly fixing the mesh plate 4 on the partition platform 3. The upper layer of the culture chamber 1 is used to place sterile filter paper and seeds, while the lower layer is used to store sterile water. After the sterile water in the lower layer evaporates, it passes through the mesh of the mesh plate 4 to reach the filter paper to provide moisture and keep the filter paper moist. This allows for long-term water storage without the need for manual labor.

[0029] like Figure 5 As shown, the sealing assembly includes a mounting groove 14 and a sealing ring 15. The mounting groove 14 is opened inside the chamber cover 2, and the sealing ring 15 is fixedly installed inside the mounting groove 14. When the chamber cover 2 and the culture chamber 1 are combined, the sealing ring 15 inside the mounting groove 14 will be compressed, causing the sealing ring 15 to fill the connection gap, preventing moisture loss and ensuring internal sterility.

[0030] like Figures 1-6 As shown, the water replenishment component includes a lifting frame 7, a baffle 8, a pipe 12, a water storage tank 13, and a water inlet 23. The lifting frame 7 is fixedly installed inside the culture chamber 1. The baffle 8 is slidably connected inside the lifting frame 7. The pipe 12 is detachably installed on the outer wall of the culture chamber 1. The water storage tank 13 is fixedly installed at the other end of the pipe 12. The water inlet 23 is located inside the culture chamber 1. When the sterile water in the lower layer is insufficient, the drive component will lower the baffle 8, causing the water inlet 23 to open, allowing the sterile water stored in the water storage tank 13 to flow in through the pipe 12. During the replenishment of sterile water in the lower layer, the baffle 8 will be driven by the drive component to gradually close the water inlet 23, thereby further reducing personnel operation and extending the interval between each water replenishment.

[0031] like Figure 3 As shown, the drive assembly includes two chute 9s, two connecting rods 10s, and two floats 11s. Each chute 9 is opened on the outer wall of the lifting frame 7, and each connecting rod 10 is fixedly installed on the outer wall of the baffle 8. The two floats 11 are fixedly connected to the other ends of the two connecting rods 10 respectively. As the amount of sterile water in the lower layer decreases, the floats 11 will descend with the horizontal plane, thereby driving the baffle 8 to move down inside the lifting frame 7 through the connecting rods 10, opening the water inlet 23 to replenish the sterile water inside the water storage tank 13. During the replenishment process, the horizontal plane will gradually rise, and the floats 11 will also rise synchronously, driving the baffle 8 to move up through the connecting rods 10, and re-closing the water inlet 23.

[0032] like Figures 1-5 As shown, the fixing assembly includes two upper insert plates 16, two slots 17, two sliding frames 18, two lower insert plates 19, and two springs 20. Each upper insert plate 16 is fixedly installed at the bottom of the chamber cover 2. The two slots 17 are respectively opened on the outer walls of the two upper insert plates 16. Each sliding frame 18 is fixedly installed on the outer wall of the culture chamber 1. The two lower insert plates 19 are slidably connected to the inside of the two sliding frames 18. The two springs 20 are respectively fixedly installed inside the sliding frames 18. The other ends of the two springs 20 are respectively fixedly connected to the outer walls of the two lower insert plates 19. When the chamber cover 2 and the culture chamber 1 are combined, the upper insert plates 16 on the chamber cover 2 will cooperate with the inclined surfaces of the lower insert plates 19 through their own inclined surfaces. As the upper insert plates 16 gradually descend, the lower insert plates 19 will... The insert plate 19 moves continuously into the sliding frame 18, compressing the spring 20. When the upper insert plate 16 moves a certain distance, its slot 17 will align with the opening of the sliding frame 18, thus eliminating the pressure on the lower insert plate 19 and the spring 20. Instantly, the elastic potential energy of the spring 20 is released, pushing the lower insert plate 19 into the slot 17, thereby fixing the position of the upper layer and fixing the cover 2. When taking out the germinator, there is no problem if it is taken out from the culture chamber 1. However, if it is taken out from the cover 2, the culture chamber 1 will fall due to insufficient friction between the cover 2 and the culture chamber 1. This situation will not occur after using the fixing component, and the elasticity of the sealing ring 15 can prevent the cover 2 from being lifted and causing the seal to fail.

[0033] like Figure 4 As shown, the auxiliary includes two preset slots 21 and two pull plates 22. The two preset slots 21 are respectively opened on the outer walls of the two sliding frames 18. The two pull plates 22 are slidably connected to the inside of the two preset slots 21. The side ends of the two pull plates 22 are respectively fixedly connected to the outer walls of the two lower insert plates 19. When it is necessary to separate the chamber cover 2 and the culture chamber 1, the lower insert plate 19 can be moved by pushing the pull plate 22, so that the lower insert plate 19 and the upper insert plate 16 are separated.

[0034] like Figure 1 As shown, both the culture chamber 1 and the chamber cover 2 are made of glass, which allows staff to directly observe the inside of the culture chamber.

[0035] like Figure 1 As shown, the outer wall of culture chamber 1 is marked with graduations, which allows staff to more intuitively understand the remaining amount of sterile liquid inside culture chamber 1.

[0036] like Figure 1 As shown, the surface of the lid of the water storage tank 13 is provided with anti-slip grooves to prevent the operator from slipping when turning the lid.

[0037] The specific working process of this utility model is as follows: First, the mesh plate 4 is placed on the partition platform 3 inside the culture chamber 1 through the partition component, and the mesh plate 4 is fixed to the card seat 5 through the connecting groove 6, dividing the culture chamber 1 into upper and lower layers. The upper layer is used to place sterile filter paper and seeds, and the lower layer stores sterile water. When the chamber cover 2 is closed, the sealing ring 15 of the sealing component is compressed to fill the connection gap, ensuring that the interior is sealed and sterile. During germination, the sterile water in the lower layer evaporates and moistens the filter paper in the upper layer through the holes of the mesh plate 4 to provide moisture for the seeds. When the water level drops, the float 11 of the drive component sinks accordingly, and drives the baffle 8 to move down in the lifting frame 7 through the connecting rod 10, opening the water inlet 23, so that the sterile water in the water storage tank 13 flows into the lower layer through the pipe 12 to replenish it. After the water level rises, the float 11 floats up and pushes the baffle 8 to reset and close the water inlet 23, realizing automatic water replenishment. Simultaneously, when the cover 2 is closed, the locking mechanism causes the upper insert plate 16 to press the lower insert plate 19, compressing the spring 20. When the slot 17 is aligned, the spring 20 is released, pushing the lower insert plate 19 into the slot 17 to secure the cover 2. When it needs to be opened, the lower insert plate 19 can be pulled out of the slot 17 by the pull plate 22 of the auxiliary component to unlock it. The entire process achieves sterile seed germination, automatic moisture retention, and stable sealing, reducing manual intervention.

Various modifications and variations can be made to this utility model by those skilled in the art.
