Description

Technical Field

[0001] This utility model belongs to the field of artificial cultivation technology of edible fungi, and relates to a container for the cultivation of Cordyceps militaris, especially a Cordyceps militaris cultivation container that can effectively isolate substrate exudate from fruiting bodies, facilitate the cleaning of accumulated liquid, and is reusable. Background Technology

[0002] Cordyceps militaris is an edible and medicinal fungus with high nutritional and medicinal value. Its artificial cultivation often uses rice, wheat, or silkworm pupae as solid substrates. During cultivation, the substrate produces and exudes liquid due to condensation or metabolism during sterilization, inoculation, and mycelial growth. If this liquid accumulates in the cultivation container and remains in prolonged contact with the base of the Cordyceps militaris fruiting body, it can easily cause the base of the fruiting body to rot due to immersion and lack of oxygen. Simultaneously, it creates conditions for the growth of other microorganisms, leading to contamination and severely impacting the yield and quality of Cordyceps militaris. Therefore, effectively managing the substrate exudate during cultivation is one of the key technical issues for achieving high-yield and high-quality Cordyceps militaris cultivation.

[0003] Several container designs for optimizing Cordyceps militaris cultivation already exist in the prior art. For example, Chinese Patent Publication No. CN207560991U discloses a "cultivation container for automated cultivation of Cordyceps militaris," which enhances the structural stability of the container body by setting wedge-shaped chamfers, a reinforcing ring at the cup mouth, and triangular reinforcing ribs to adapt it to mechanized production, and uses a cup lid with a breathable membrane to meet gas exchange requirements. This solution mainly solves the problem of the container's mechanical strength and automation adaptability, but it does not address the technical means for effectively isolating and managing the substrate exudate generated during cultivation, and fails to fundamentally solve the problem of fruiting body rot and pollution caused by liquid accumulation.

[0004] For example, Chinese Patent Publication No. CN105981587A discloses a "Separate Cultivation Container for Cordyceps militaris," which uses a separate base, lid, and transparent cover design to adapt to the different needs of light avoidance during mycelial cultivation and light transmission during the emergence stage. It also regulates gas exchange by setting through-holes and openable / closable ventilation holes. This solution focuses on meeting the light and ventilation requirements of different growth stages through a separate structure and facilitates harvesting. However, it also lacks a specialized structure for the directional flow, collection, and isolation of substrate exudate, leaving the problem of liquid accumulation and contamination still present.

[0005] In summary, existing Cordyceps militaris cultivation containers, while improving structural strength and automation, or optimizing light and gas exchange management, fail to provide a comprehensive solution that effectively isolates the fruiting bodies from the substrate exudate and allows for easy cleaning of accumulated liquid for container reuse. Substrate exudate management remains a critical technical bottleneck in the current artificial cultivation of Cordyceps militaris. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a container for the cultivation of Cordyceps militaris. Through the built-in filter and flow guiding module that can be removed and placed as a whole, the fruiting body is physically isolated from the substrate exudate, and the accumulated liquid is directed, stored in a controlled manner, and cleaned conveniently. This fundamentally solves the problem of fruiting body rot and pollution caused by accumulated liquid, and enables the container to be reused.

[0007] Through long-term exploration and experimentation, as well as numerous trials and efforts, the inventors have continuously reformed and innovated to solve the above-mentioned technical problems. The technical solution provided by this utility model is a container for cultivating Cordyceps militaris, comprising a container body and a lid, and further including a functional integrated unit disposed inside the container body. The functional integration unit includes a matrix-supported filtration unit, a liquid-guiding and storage unit, and a lifting operation component; The liquid-guiding and storage unit is fixedly connected below the matrix-supporting filtration unit; A one-way flow control component is provided at the bottom outlet of the flow-guiding and storage unit; The lifting operation component is rotatably connected to the upper side wall of the liquid guiding and storage unit.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention integrates a substrate-supporting filtration unit, a liquid-guiding and storage unit, and a unidirectional flow control component into a single, removable functional unit. This creates an internal liquid self-management closed system, effectively isolating the fruiting body growth area from the liquid accumulation chamber. This fundamentally avoids the rotting and contamination problems caused by the seepage of liquid at the base of the fruiting body. Simultaneously, utilizing the unidirectional flow control component's automatic opening and closing characteristic based on liquid level and pressure, it can both direct excess liquid to the bottom chamber and retain a suitable amount of liquid in the liquid-guiding and storage unit. This liquid, through natural evaporation, continuously provides a moisturizing environment for the upper substrate, optimizing the micro-ecology. Combined with a rotatable lifting operation component, the entire process of liquid cleaning and device recycling is convenient and efficient, significantly reducing post-cultivation maintenance costs and labor intensity, and ensuring reliable reuse of the container. Thus, while ensuring the yield and quality of Cordyceps militaris, it achieves multiple technical effects of pollution prevention, easy cleaning, and reusability.

[0009] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the matrix-supported filtration unit includes a disc-shaped structure with filter holes and a sidewall surrounding the edge of the disc-shaped structure, the sidewall being adapted to the inner wall of the container body.

[0010] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: The use of a disc-shaped structure with sidewalls that is compatible with the inner wall of the container ensures the stability of the substrate load and enables effective collection and diversion of the exudate in the entire circumference, thus eliminating liquid bypass leakage.

[0011] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the flow-guiding and storage unit includes a liquid collection funnel connected to the matrix-supporting filter unit and a liquid storage section located below the liquid collection funnel, and the unidirectional flow-guiding control component is disposed at the bottom of the liquid storage section.

[0012] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: The liquid collection funnel and liquid storage section are arranged in a partitioned manner, so that the liquid accumulation temporary storage area and the unidirectional flow control component are concentrated at the bottom of the liquid storage section, realizing the modular centralization of liquid collection and discharge functions.

[0013] Based on the above technical solution, the present invention can be further improved as follows: Furthermore: the unidirectional flow control component includes a valve plate, a magnetic suction part, and a corner limiting block; The valve plate is hinged to the outlet of the liquid storage section via a rotating shaft; The magnetic suction part is disposed at the periphery of the outlet of the valve plate and the liquid storage part; The corner limiting block is located at the outlet of the liquid storage section and is used to limit the opening angle of the valve plate.

[0014] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: Through the synergistic effect of the magnetic suction part and the corner limiting block, the valve plate can be opened and closed precisely based on the liquid level pressure, which not only ensures reliable discharge when there is excessive liquid accumulation, but also avoids problems such as liquid retention or poor sealing caused by excessive valve plate opening.

[0015] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, when the valve plate of the unidirectional flow control component is in the closed state, there is a gap between its bottom and the inner bottom wall of the container body.

[0016] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: This gap ensures that the liquid accumulated at the bottom of the container can be completely drained, avoiding the formation of contamination dead zones due to residual liquid accumulation, while also preventing the valve plate from adhering to the bottom wall of the container, making it easy to clean thoroughly.

[0017] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the lifting operation component is a U-shaped handle, the two ends of which are rotatably connected to the connection holes provided on the side wall of the matrix-supporting filter unit or the side wall of the liquid-guiding storage unit via rotating shafts.

[0018] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: The U-shaped handle connected by a pivot allows for quick switching between operation and storage modes, improving ease of operation while avoiding occupying valuable vertical growth space inside the container during cultivation.

[0019] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the U-shaped handle has two stable working positions around the pivot: a first working position in which the crossbar of the U-shaped handle is located directly above the functional integration unit; and a second working position in which the crossbar of the U-shaped handle is against the side of the functional integration unit.

[0020] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: This bistable structure ensures that the handle provides stable support when lifting, while allowing space to grow when stored, achieving an optimal balance between ease of operation and space utilization.

[0021] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, a vent is provided on the cover, and a sterile breathable membrane is fixedly covered on the vent.

[0022] Compared with the existing technology, the beneficial effects of adopting the above-mentioned further technical solution are as follows: This structure ensures the gas exchange required for the growth of Cordyceps militaris while achieving reliable physical blocking of airborne bacteria through a sterile and breathable membrane, thus balancing ventilation needs with pollution control.

[0023] Furthermore, the material of the functional integration unit is polypropylene. Attached Figure Description

Detailed Implementation

[0034] The following description, in conjunction with the accompanying drawings and a specific embodiment, will be provided.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0037] See Figures 1 to 8 The container for cultivating Cordyceps militaris described in this embodiment has the following overall structure: Figures 1 to 3 As shown, it mainly includes a container body 100, a cover 500, and a functional integrated unit disposed inside the container body 100. The functional integrated unit consists of a matrix-supporting filtration unit 200, a liquid-guiding storage unit 300, and a lifting operation component 400, which are integrated into a module that can be picked up and put down as a whole.

[0038] In this embodiment, the container body 100 is a hollow, inverted frustum-shaped structure with a bottom diameter of approximately 80 mm, a top diameter of approximately 120 mm, and a height of approximately 80 mm. It is made of polypropylene (PP) material, which possesses good chemical stability and mechanical strength. A lid 500 covers the top of the container body 100 and has a vent 510. A sterile, breathable membrane 520 (e.g., ...) is fixedly attached to the vent 510. Figure 1 , Figure 2 (As shown), to ensure the gas exchange required during the growth of Cordyceps militaris, while effectively blocking airborne bacteria.

[0039] like Figures 3 to 6 As shown, the substrate-supporting filtration unit 200 includes a disc-shaped structure with multiple filter holes 210 and a sidewall 220 surrounding the edge of the disc-shaped structure. The sidewall 220 is adapted to the inner wall of the container body 100 to ensure that the unit is stably placed inside the container and that liquid does not leak from the edge. In a preferred embodiment, the filter holes 210 on the disc-shaped structure have a diameter of 0.2 mm, and the six filter holes 210 are evenly distributed on the circumference of the same circle, which can effectively block substrate particles such as rice or silkworm pupae, while allowing substrate exudate to pass through. This unit is used to support the cultivation substrate and to smoothly guide the exudate downwards.

[0040] See Figures 3 to 8 The liquid-guiding and storage unit 300 is fixedly or detachably connected to the substrate-supporting filter unit 200 and includes a liquid-collecting funnel 310 connected to the substrate-supporting filter unit 200 and a liquid-storing part 320 located below the liquid-collecting funnel 310. In a preferred embodiment, the top diameter of the liquid-collecting funnel 310 is approximately 100 mm, which can completely cover the filter pore area of ​​the substrate-supporting filter unit 200 to ensure that the liquid is collected in a concentrated manner; a one-way flow control component 330 is provided at the bottom outlet of the liquid-storing part 320.

[0041] One-way flow control component 330, such as Figure 7 and Figure 8 As shown, the system includes a valve plate 331, a magnetic suction part 332, and a corner limiting block 333. The valve plate 331 is hinged to the outlet of the liquid storage part 320 via a rotating shaft. The magnetic suction part 332 is disposed around the outlet of the valve plate 331 and the liquid storage part 320, and uses magnetic force to keep the valve plate 331 closed when there is no hydraulic pressure or low pressure. The corner limiting block 333 is disposed at the outlet of the liquid storage part 320 to limit the opening angle of the valve plate 331. In this embodiment, the maximum opening angle does not exceed 3°. In the closed state, there is a gap between the bottom of the valve plate 331 and the inner bottom wall of the container body 100. It is recommended that this gap be no less than 5mm to ensure that the liquid accumulated at the bottom of the container can be completely drained and to avoid residue.

[0042] The lifting operation component 400 is a U-shaped handle, the two ends of which are rotatably connected to the connection holes provided on the side wall of the liquid guiding and storage unit 300 via rotating shafts (e.g., Figures 3 to 6 (As shown). The U-shaped handle has two stable working positions around the rotating shaft: First working position: The crossbar of the U-shaped handle is located directly above the functional integration unit, making it easy to lift the entire unit; Second working position: The crossbar of the U-shaped handle rests against the side of the functional integration unit to avoid occupying the growth space of the Cordyceps militaris fruiting body.

[0043] The working principle of the container used for Cordyceps militaris cultivation described in this embodiment is as follows: Cultivation stage: A cultivation substrate such as rice or silkworm pupae is laid on the disc-shaped structure of the substrate-supporting filter unit 200, and Cordyceps militaris spawn is inoculated. During the mycelial growth and fruiting body formation, the exudate produced by the substrate drips through the filter holes 210 into the liquid collection funnel 310, and then flows into the liquid storage section 320 after being guided. When the accumulated liquid reaches a certain threshold (e.g., mass G1), the liquid pressure overcomes the magnetic force of the magnetic suction section 332, pushing the valve plate 331 to open, and the accumulated liquid flows unidirectionally into the bottom of the container body 100 for temporary storage; when the liquid level drops, the magnetic suction section 332 resets and closes the valve plate 331 to prevent the bottom accumulated liquid from flowing back, while retaining an appropriate amount of liquid to provide moisture to the substrate through natural evaporation.

[0044] Cleanup and reuse phase: After cultivation, rotate the lifting operation component 400 to the first working position and lift it upwards to remove the entire functional integrated unit (including the substrate-bearing filtration unit 200, the liquid-guiding storage unit 300, and the unidirectional flow control component 330). After emptying the accumulated liquid at the bottom of the container body 100, the functional integrated unit can be put back into the container, allowing the container to be reused.

[0045] This embodiment effectively isolates the growth area of ​​Cordyceps militaris fruiting bodies from the sap accumulation chamber through the internal liquid self-management and sealing system of the functional integration unit, fundamentally avoiding the problems of rotting and contamination caused by the base of the fruiting bodies due to the infiltration of exudate. Simultaneously, the automatic opening and closing characteristics of the unidirectional flow control component 330 optimize the micro-ecological environment; combined with the rotatable lifting operation component 400, the process of sap accumulation cleaning and device recycling is convenient and efficient, significantly reducing post-cultivation maintenance costs and labor intensity, and ensuring the reliable reuse of the container.

[0046] Although this embodiment describes one implementation of the present invention in detail, those skilled in the art can make various modifications without departing from the core concept of the present invention. For example, the size and distribution of the filter pores 210 can be adjusted according to the substrate type; the magnetic force of the magnetic suction part 332 can be set according to the liquid accumulation threshold requirement; the specific shape and connection method of the lifting operation component 400 can also be different. These modifications should all be considered to fall within the protection scope of the present invention.
