Description

Technical Field

[0001] This utility model belongs to the field of agricultural and horticultural technology, and in particular relates to a lily pollen drying and preservation box. Background Technology

[0002] Artificial hybridization pollination is a common technique in lily breeding. Breeders usually collect the anthers the day before the flowers open, place them in petri dishes to disperse pollen indoors, and take the petri dishes to the field the next day. They then use cotton swabs to collect the pollen and carry out the pollination operation according to the prepared hybridization combination. After pollination, the petri dishes are placed in the refrigerator for refrigeration. This process is repeated to complete the hybridization pollination throughout the entire flowering period.

[0003] In long-term artificial hybridization pollination, the following technical problems exist: First, due to differences in genotype and planting time among different lily varieties, their flowering periods are difficult to synchronize completely. It is necessary to store pollen from early-flowering lily varieties for hybridization with later-flowering varieties. Second, pollen is generally stored for short or long periods at 4℃, -18℃, and ultra-low temperatures. The lids of the culture dishes containing pollen are loose and poorly sealed, making it easy for pollen to spill due to collisions in the refrigerator, resulting in pollen loss. Furthermore, the shallowness and limited capacity of the culture dishes make them unsuitable for storing large quantities of pollen. Labeling pollen type information can only be done on the lid, making it inconvenient to find the desired pollen. Third, culture dishes cannot be completely sealed, and the pollen stored within is affected by humidity and gas environment within the refrigerator, making it difficult to maintain an ideal dry storage condition, severely impacting pollen viability. Utility Model Content

[0004] To address the aforementioned issues of frequent pollen transfer between the field and laboratory during artificial hybridization pollination, traditional petri dishes suffer from poor sealing leading to pollen moisture absorption and spoilage, open structures causing pollen spillage, and flat containers hindering categorized storage. Limited information labeling areas also result in low retrieval efficiency. Particularly problematic are the mixing of multiple batches of pollen during mixed-batch storage, which can lead to confusion and uncontrolled humidity during low-temperature storage, directly impacting pollen viability. This invention provides a lily pollen drying and preservation box. After anther harvesting, pollen is directly dispersed within the box and then dried and stored in a refrigerator. The outer side of the container can be labeled with pollen type, harvesting time, and other information for easy retrieval. This ensures long-term pollen preservation, enables staggered pollination, and improves hybridization breeding efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model discloses a lily pollen drying and preservation box, comprising a C layer and a detachable A layer and / or B layer disposed on the C layer, which together form a two- or three-layer storage box. The bottom of the A layer and the B layer both have partitions with multiple through holes. The A layer is a closed space with a sealed opening and a partition I with multiple through holes I at the bottom, and a desiccant is placed inside the A layer. The B layer is an open box with a partition II with multiple through holes II at the bottom, which holds freshly harvested flowers and anthers. The C layer is an open box that holds dried pollen. The bottom of the A layer and the B layer both have a detachable sealing connection structure that matches the top of the C layer. The top structures of the B layer and the C layer are the same.

[0007] Furthermore, the sealing feature of layer A is a sealed, openable cover for adding desiccant, which is opened on the side wall of the layer A box.

[0008] Furthermore, the through holes I on the A-layer partition I are staggered, with a diameter of 1.5-2.5mm, which is smaller than the outer diameter of the desiccant particles.

[0009] Furthermore, the through holes II on the B-layer partition II are staggered, with a diameter of 1.5-2.5 mm, which is smaller than the minimum diameter of the anther.

[0010] Furthermore, the corners of the assembled box are rounded, and the box material is a transparent polyethylene material that can withstand temperatures as low as -80℃.

[0011] Furthermore, layers A and B are provided with an integral partition I or partition II at the bottom of the box body, and the bottom of partition I or partition II has a slot for connecting with the box body.

[0012] Furthermore, an information label pasting area is also provided on the side wall of layer C.

[0013] Furthermore, a humidity sensor is also provided at the sealing point of layer A. The humidity sensor is electrically connected to a display screen located on the outside of the box, and is used to monitor the humidity inside layer A in real time and display the humidity value on the display screen.

[0014] Furthermore, a temperature sensor is also installed inside the C layer. The temperature sensor is electrically connected to a display screen located on the outside of the box, which is used to monitor the temperature inside the C layer in real time and display the temperature value on the display screen.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model addresses the contradiction between airtightness and ease of access during pollen storage. Firstly, it utilizes a layered structure to achieve functional zoning, establishing independent drying and storage units. Secondly, to adapt to different storage stages, a modular combination method is adopted to allow for variable container shapes. Furthermore, a physical isolation structure is designed to prevent material spillage while maintaining environmental control capabilities. Finally, standardized interfaces enable the stacking of multiple containers, forming a unified identification system. This achieves long-term effective pollen storage and facilitates staggered pollination.

[0017] 2. This invention collects pollen from different varieties of lilies separately in plastic boxes, facilitating pollen sorting, drying, and long-term storage. The pollen drying and storage boxes are of moderate size, can be stacked in the refrigerator for long-term storage, have good airtightness, and offer advantages such as space saving, moisture protection, spill prevention, shock resistance, and convenient information retrieval. The pollen drying and storage boxes can be stored long-term at 4℃, -18℃, and ultra-low temperature freezers, prolonging pollen activity and facilitating cross-pollination of parent plants with different flowering periods.

[0018] 3. When using this invention, an appropriate amount of pollen is taken with a spatula and placed into cryovials of different volumes according to the pollination amount during the flowering period. This facilitates storage, avoids pollen waste, and prevents problems such as reduced pollen activity and cross-contamination caused by prolonged exposure to high temperatures in the field. This provides convenience for the artificial hybridization and pollination of lilies and other horticultural plants. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example: This utility model discloses a lily pollen drying and preservation box, comprising a C layer 4 and a detachable A layer 2 and / or B layer 3 disposed on the C layer 4, which together form a two- or three-layer storage box. The bottom of the A layer 2 and the B layer 3 are both equipped with partitions with multiple through holes. The A layer 2 is a closed space with a sealed opening, and the bottom is equipped with a partition I 6 with multiple through holes I, in which a desiccant is disposed. The B layer 3 is an open box, and the bottom is equipped with a partition II 8 with multiple through holes II, which holds freshly harvested flowers and anthers. The C layer 4 is an open box, which holds dried pollen. The bottom of the A layer 2 and the B layer 3 are both equipped with a detachable sealing connection structure that matches the top of the C layer 4. The top structure of the B layer 3 is the same as the top structure of the C layer 4.

[0024] Among them, layer C4 serves as the basic storage unit to hold dried pollen and is used to store dried pollen for a long time. Specifically, it can be made of rectangular transparent polyethylene material, and the top box serves as a standardized interface to achieve flexible configuration of multiple containers stacked.

[0025] Layer A, 2, contains a built-in desiccant to form a closed drying space. Specifically, the desiccant can be dispensed using a side-wall opening and closing sealing cover 5. The bottom partition I 6 has staggered through-holes I forming gas exchange channels, and the limited pore size prevents desiccant particles from leaking out. The desiccant is blue color-changing silica gel granules; its initial color is blue, changing to purple as the moisture absorption increases, and finally to pink. The silica gel granules should be replaced promptly at this point.

[0026] Layer B3 serves as a temporary storage unit for fresh anthers. It is a box with one open end, acting as a transitional container for fresh anthers. The bottom is equipped with a partition II8 structure with through holes II. The hole diameter is smaller than the anther diameter to allow air convection while the dried pollen falls into layer C4. The top of layer B3 has the same interface structure as layer C4, enabling quick disassembly and assembly.

[0027] Each layer is detachable and combinable through a bottom sealing connection structure. The sealing connection structure refers to the snap-fit ​​structure at the joint between layers. Specifically, a concave-convex interlocking design can be used to achieve an airtight connection. Standardized interface dimensions ensure compatible combination between layers.

[0028] Specifically, when long-term preservation of dried pollen is required, layer A2 and layer C4 are combined to form a double-layer structure. The desiccant in layer A2 continuously absorbs moisture from layer C4 through the pores, while the closed space prevents external moisture from entering.

[0029] When new anthers need to be harvested, undispersed anthers are collected and stored in layer B3. Layer B3 is then stacked on top of layer C4 to form a double-layer temporary storage structure. After harvesting, layer A2 is stacked on top of layer B3 to form a sealed three-layer box, which is then brought indoors for natural pollen dispersal. During indoor pollen dispersal, layer A2 is removed, and dried pollen is collected promptly. Using the through-holes II on partition II8 of layer B3, the dried pollen is sieved into layer C4. The pore size of through-holes II on partition II8 forms a physical barrier to prevent anthers from falling off. Within 24 hours of pollen dispersal, layers A2 and C4 are combined and placed at low temperatures to maintain pollen activity, achieving pollen drying and preservation. Standardized sealing structures at the joints of each layer ensure overall airtightness, while transparent materials facilitate observation of the internal condition. Information labels on the side walls provide categorization identification.

[0030] Compared to existing technologies, traditional petri dishes have a single-layer open structure, which cannot achieve zoned control of desiccant and pollen. When stacked, they lack a stable connection and are prone to spillage, and information labeling is limited to the surface of the lid. This application achieves functional zoning through a modular layered design, maintaining airtightness. The perforated partitions allow for material exchange while forming physical barriers, the standardized connection structure ensures the stability of multi-layer combinations, and the dedicated label area on the side wall improves information identification efficiency.

[0031] Through the above technical solutions, each functional unit is independently isolated during pollen storage to avoid cross-contamination; the sealed connection structure effectively prevents spillage accidents during transportation or low-temperature storage; the modular combination method adapts to the needs of different storage stages and reduces the frequency of container replacement; the combination of transparent materials and dedicated label areas enables rapid identification and status monitoring; and the partition hole design ensures ventilation efficiency while precisely controlling the material transfer path.

[0032] Furthermore, the sealing feature of layer A 2 is a closable cover 5 for adding desiccant, located on the side wall of the layer A 2 box. This closable cover is an independent opening and closing structure located on the side wall of the box, specifically implemented using a flip-top design with a sealing ring, achieving a sealed closure via a snap or magnetic attraction. Its function is to provide an independent channel for adding desiccant, avoiding damage to the sealing integrity of other parts of the box. When it is necessary to add or replace desiccant, only the closable cover on the side wall needs to be operated, without disassembling the entire layer A or opening the top structure. When the cover is closed, the sealing ring is compressed and deformed to fill the gap, preventing external moisture from seeping in through the side wall opening. This partial opening and closing method maintains the overall airtightness of layer A 2 as a closed space and prevents desiccant particles from scattering into adjacent layers due to vibration or tilting during operation.

[0033] Compared to existing technologies, traditional petri dishes require the complete removal or lifting of the lid, exposing the internal storage environment to the outside world and making them susceptible to moisture intrusion and pollen contamination. In contrast, the side-wall sealed opening and closing lid, through its spatially separated independent operating area, restricts the opening and closing action to a localized area, ensuring the safe release of the desiccant while maintaining overall airtightness.

[0034] Through the above technical solution, this application solves the problem of insufficient sealing during desiccant dispensing, ensuring effective isolation between the desiccant storage environment and the outside world. The independently opening and closing structure of the side walls avoids humidity fluctuations caused by overall opening, while simplifying the operation steps and reducing the risk of desiccant particle leakage due to frequent opening and closing, thereby maintaining the stability of the pollen storage environment.

[0035] Furthermore, the through holes I on the partition I6 of layer A2 are staggered, with a diameter of 1.5-2.5mm, which is smaller than the outer diameter of the desiccant particles.

[0036] The staggered arrangement refers to the non-linear distribution of through-holes I on partition I6, which can be achieved using a diamond or honeycomb grid layout. This increases the number of through-holes per unit area, creating multi-directional airflow channels. The pore diameter is smaller than the outer diameter of the desiccant particles, depending on the size of the desiccant particles used. In this example, the diameter of through-hole I is 2mm, ensuring that desiccant particles cannot fall into the lower layer through the holes in partition I6, thus avoiding contamination of the anthers or pollen stored below.

[0037] Compared to existing technologies, traditional short-term pollen preservation often uses a single-layer container in a petri dish without a desiccant. Traditional long-term pollen preservation typically involves placing dried pollen in a plastic cryovial, with a cotton ball separating the pollen from the desiccant, which is then placed at the cryovial's seal. This method results in some pollen adhering to the cotton surface, leading to pollen waste, especially for varieties with low pollen yields. Furthermore, retrieving the pollen requires first removing the desiccant, then the cotton ball, and finally the pollen, making the process cumbersome. This new solution utilizes a rigid partition structure with specific pore size parameters. While maintaining the desiccant's hygroscopic function, it constructs a reliable physical barrier, effectively separating the desiccant layer from the pollen storage layer. This solves the pollen waste problem inherent in traditional preservation methods, is easy to operate, and is suitable for long-term stable pollen preservation at low temperatures.

[0038] Furthermore, the through holes II on the partition II 8 of layer B 3 are arranged in an alternating manner, with a hole diameter of 1.5-2.5mm, which is smaller than the minimum diameter of the anther.

[0039] This application further proposes that the partition II 8 of layer B has staggered through holes II with a diameter of 1.5-2.5 mm, which is smaller than the minimum diameter of the anthers. The staggered arrangement of the through holes II means that the through holes are arranged in a non-linear manner on the partition II 8, specifically through a rectangular array with staggered distribution or a hexagonal honeycomb arrangement. This layout allows the pollen to easily fall into the lower layer C after being dispersed. The diameter of the through holes II being smaller than the minimum diameter of the anthers means that the hole size, after screening, only allows pollen grains to pass through. This can be achieved through laser drilling or mold forming processes. This size limitation prevents the anthers from leaking down. The partition and the slot are fitted by embedding the edge of the partition into a positioning groove in the side wall of the box. This can be achieved by using injection molding to form a guide groove 0.5-1 mm deep inside the box. This structure maintains the flatness of the partition surface.

[0040] Specifically, when fresh anthers are placed in layer B3, pollen particles generated during natural pollination can fall into layer C4 through the through-holes II of partition II8. The staggered arrangement of through-holes II provides multi-point support for the anthers on the surface of partition II8, preventing anthers from accumulating in a single area and causing blockage. The pore size is strictly selected to ensure smooth pollen passage while forming a physical barrier to prevent the anthers from penetrating the partition. In the airflow channel generated by the desiccant, the distribution density and pore size of through-holes II form a uniform ventilation path, maintaining continuous airflow circulation between layer B3 and layer C4.

[0041] Compared to existing technologies, traditional petri dishes use a single container to store anthers and pollen. Once the anthers have dispersed, they have no further function, and storing them mixed with pollen occupies storage space. Furthermore, the anthers increase humidity within the petri dish, leading to rotting and mold, which affects pollen purity and viability. This application addresses this issue by using a partition structure with specific pore sizes and arrangements to create a physical isolation layer between the anther and pollen storage spaces while maintaining the natural flow of pollen. This design overcomes the technical limitations of traditional open containers that cannot control material flow in layers.

[0042] Through the above technical solution, this application can effectively prevent anthers from accidentally mixing into the pollen storage layer during storage, avoiding cross-contamination between the desiccant and pollen. The dual control of the perforation layout and aperture size of the partition maintains the airflow channel required for pollen drying. This structure achieves the dual technical effects of isolating the storage space and maintaining the drying environment in order to ensure pollen viability.

[0043] Furthermore, the corners of the assembled box are rounded, and the box material is a transparent polyethylene material that can withstand temperatures as low as -80℃.

[0044] This application further proposes that the corners of the assembled box are rounded, and the box material is polyethylene resistant to temperatures as low as -80°C. The rounded corners refer to the arc-shaped transition structure at the edges of the box, which can be achieved through a circular radius design. This eliminates stress concentration areas at right-angled edges, reducing the risk of breakage due to low-temperature shrinkage or impact. The -80°C-resistant polyethylene refers to the use of a specially modified transparent polyethylene material to meet the requirements for resistance to brittle fracture in ultra-low temperature environments, facilitating external observation of pollen conditions.

[0045] Specifically, the rounded corners of the box disperse external impact and internal stress, preventing structural cracking caused by sudden temperature changes or physical collisions. The low-temperature resistant polyethylene material maintains its flexibility under ultra-low temperature storage conditions, preventing the box from becoming brittle and cracking. The use of transparent polyethylene material allows for easy viewing of the internal contents when observing pollen status or label information.

[0046] Compared to existing technologies, traditional culture dishes are typically made of round, ordinary plastic, which is prone to corner cracking due to stress concentration during low-temperature storage. Furthermore, ordinary plastic is susceptible to brittleness and failure at -80°C. This solution, through rounded corner design and low-temperature resistant materials, significantly improves the structural integrity and lifespan of the container in ultra-low temperature environments. Through the above technical solution, this application achieves stable morphological maintenance of the pollen storage box in ultra-low temperature environments, avoiding damage caused by material brittleness or structural defects. Simultaneously, the optional transparent material design provides convenient conditions for pollen status monitoring.

[0047] Furthermore, the opposite sides of the A-layer 2 and B-layer 3 boxes have slots that mate with the thickness of their respective partitions I6 or II8, allowing the partitions to be securely inserted into these slots. These slots are elongated grooves on the opposite sides of the boxes, with the width of the grooves matching the thickness of partition I6 or II8 with either a clearance fit or an interference fit. Specifically, the groove structure can be integrally formed on the side of the box using injection molding. By matching the dimensions of the grooves with those of partition I6 or II8, the partitions I6 or II8 are kept in a fixed horizontal position after insertion. Secure insertion means that the edges of partition I6 or II8 are in close contact with the inner wall of the slot. This can be achieved by providing elastic protrusions on the edges of partition I6 or II8 or by designing anti-slip textures on the inner wall of the slot, preventing partition I6 or II8 from moving freely in the vertical direction.

[0048] Specifically, when partition I6 or partition II8 is inserted along the slots on the side of the box, its thickness is completely constrained by the inner walls of the slots on both sides, thus eliminating the possibility of lateral displacement. After partition I6 or partition II8 is fully embedded, its upper and lower surfaces form contact limits with the top and bottom of the slots, preventing vertical detachment due to vibration or tilting. This assembly method ensures that the anther layer and desiccant layer maintain structural integrity during transportation, preventing pollen leakage through the gaps between partition I6 or partition II8.

[0049] Compared to existing technologies, conventional petri dishes rely solely on simple flat placement when storing pollen, lacking effective fixation of the partition structure. By utilizing the mechanical cooperation between the slots and partitions, the structural stability of the multi-layered storage unit is achieved, overcoming the pollen mixing problem caused by partition displacement during low-temperature storage or transportation in traditional containers. Through this technical solution, this application effectively prevents the internal partitions of the container from shifting or detaching under external forces, ensuring that the anther layer and desiccant layer maintain their predetermined relative positions. This avoids unexpected pollen leakage due to structural instability during low-temperature storage or field transportation, thus improving the reliability of pollen preservation.

[0050] Furthermore, an information label pasting area 7 is also provided on the side wall of layer C4. The information label pasting area 7 refers to the physical structure on the surface of the side wall of layer C4 for fixing the information label. Specifically, it can be implemented using a transparent label bag or a matte sticker area. The transparent label bag is fixed to the side wall of the box via a heat-pressing process, facilitating label insertion or replacement; the matte sticker area has a roughened surface formed through surface treatment to enhance label adhesion. This structure, by providing a fixed position, ensures the correspondence between the label and the pollen, avoiding information confusion caused by label movement or detachment.

[0051] Specifically, layer C4 serves as the open box for storing dried pollen. Information label affixing areas 7 are provided on its side wall surface, allowing operators to directly affix labels containing information such as pollen type, collection time, and storage conditions. Because the labels are located on the side wall rather than the top, they remain visible even when multiple layers are stacked or densely stored, facilitating quick identification of the target pollen. The label affixing area is treated with anti-slip or anti-detachment materials to prevent labels from falling off due to handling or material shrinkage in low-temperature environments. The label positions on the side wall are separated from the pollen storage space to prevent the labels from contacting pollen or becoming damp, ensuring the information remains clear and legible over the long term.

[0052] Compared to existing technologies, traditional petri dishes can only be marked by handwriting on the lid surface, requiring individual flipping to find the correct label when stacked in multiple layers. Furthermore, the labels are easily blurred by friction or condensation. This solution, by fixing the label position and optimizing the adhesive structure, makes the information display more intuitive and more resistant to interference, while avoiding label damage caused by frequent container movement. Through this technical solution, this application solves the problems of inconvenient labeling and difficulty in finding pollen category information, ensuring that different batches of pollen can still be quickly and accurately identified even when stored at low temperatures or densely packed, reducing the risk of hybridization errors due to information confusion during artificial pollination.

[0053] Furthermore, in another embodiment of this application, a common desiccant is used, and a humidity sensor is also provided at the sealing point of layer A 2. The humidity sensor is electrically connected to a display screen located on the outside of the box, for real-time monitoring of the humidity inside layer A and displaying the humidity value on the display screen.

[0054] The humidity sensor is an electronic component that detects the moisture content in the gaseous environment. It is an existing, outsourced component and can be implemented using either a capacitive or resistive sensor. Its installation location is chosen at the A-layer seal, allowing direct contact with the gaseous environment of the desiccant space while avoiding physical interference with internal materials. The display screen is an output device that receives sensor signals and converts them into visual data. It is also an existing, outsourced component and can be implemented using an LCD or LED display module. It is fixed externally to the box for easy reading by the operator.

[0055] Specifically, when the desiccant absorbs moisture from the environment inside layer A, the humidity sensor generates an electrical signal by detecting changes in gas humidity. This signal is transmitted to an external display screen and converted into a readable value. By observing the real-time data on the display screen, operators can determine whether the desiccant has failed or whether the ambient humidity exceeds a set threshold. If abnormal humidity is detected, the desiccant can be replaced or storage conditions adjusted promptly. The status assessment can be completed without opening the box, maintaining the box's airtightness and avoiding the risk of moisture intrusion or pollen contamination caused by frequent opening.

[0056] Compared to existing technologies, traditional methods of preserving pollen in petri dishes require periodic checks of the desiccant's state or reliance on empirical estimations, resulting in monitoring lag and potential disruption of the sealed environment. This solution, through real-time monitoring and data visualization, accurately tracks the desiccant's effectiveness, allowing for intervention at the initial stage of humidity anomalies to maintain a stable dry environment. Through this technical solution, this application achieves dynamic monitoring of desiccant effectiveness during pollen preservation, solving the problem of decreased pollen viability due to uncontrollable humidity and ensuring that the pollen storage environment remains consistently dry.

[0057] Furthermore, in another embodiment of this application, a temperature sensor is also provided inside the C layer 4. The temperature sensor is electrically connected to a display screen located on the outside of the box, and is used to monitor the temperature inside the C layer in real time and display the temperature value on the display screen.

[0058] The temperature sensor, a device that converts temperature changes into electrical signals through physical effects, is an existing purchased component. It can be implemented using a thermistor or thermocouple. Its measuring end directly contacts the internal space of the C layer to capture the actual temperature data of the pollen storage environment. The display screen, an electronic component with data visualization capabilities, is also an existing purchased component. It can be implemented using an LCD screen or e-ink screen. Its signal input end is connected to the temperature sensor circuit to convert the temperature values ​​collected by the sensor into visualized information in real time.

[0059] Specifically, the temperature sensor is integrated into the four side walls or bottom of layer C, with its probe extending into the space where pollen is stored. When the container is in a low-temperature storage environment, the sensor continuously monitors the temperature changes of the microenvironment where the pollen is located. The analog signals collected by the sensor are converted into digital signals by the built-in circuit and transmitted to the display screen on the outside of the container. By observing the temperature changes on the display screen, users can directly determine whether the storage environment is within the preset low-temperature range, such as -18°C or ultra-low temperature conditions. When the temperature rises abnormally, the fluctuations in the display screen can prompt users to check the operating status of the refrigeration equipment or adjust the pollen storage position in a timely manner, avoiding temperature runaway due to equipment failure or human error.

[0060] Compared to existing technologies, traditional petri dishes rely on the refrigerator's own temperature display for indirect monitoring, which cannot accurately reflect the actual storage temperature of pollen. This solution, however, achieves dual verification of the storage medium and ambient temperature by placing an independent sensor inside the pollen container. For example, when the refrigerator's internal temperature fluctuates temporarily due to frequent door opening and closing, the sensor inside the petri dish can still accurately reflect the real-time temperature of the pollen's microenvironment, avoiding monitoring blind spots caused by equipment display errors or ambient temperature lag. Through this technical solution, this application can directly monitor the temperature status of the pollen storage space and promptly detect abnormal temperature fluctuations during low-temperature storage. Operators can obtain data through an external display screen without opening the container, effectively avoiding temperature interference caused by repeated opening and observation in traditional methods. This design, through a closed-loop monitoring system, ensures that the pollen is always at the optimal storage temperature, preventing temperature rises due to equipment failure or operational errors, thereby maintaining pollen viability stability.

[0061] Components not described in detail in this application are all existing conventional technologies and will not be described further here.

[0062] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
