Description

Technical Field

[0001] This invention relates to the field of edible fungi cultivation technology, and more specifically, to an edible fungi cultivation device with a watering mechanism. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. China has over 350 known species of edible fungi, including common ones such as shiitake, straw mushroom, button mushroom, wood ear fungus, silver ear fungus, monkey head mushroom, bamboo fungus, matsutake, button mushroom, red mushroom, reishi mushroom, cordyceps, truffle, white lingzhi mushroom, and porcini. As macrofungi available for human consumption, edible fungi are extensively cultivated artificially. Controlling temperature, humidity, and ventilation are key techniques in edible fungi cultivation. However, existing humidification systems in incubators are neither uniform nor convenient, resulting in inconsistent quality of the edible fungi.

[0003] To achieve mass cultivation, multiple culture bags are typically placed inside a single incubator. For example, Chinese Patent CN109348985A discloses a household edible mushroom incubator, comprising a base box, a plurality of expansion boxes, and a lid; the base box, each of the expansion boxes, and the lid are detachably connected from bottom to top via a snap-fit ​​structure to form the incubator; a plurality of mushroom bag supports are fixedly installed inside the base box and the expansion boxes; a water pipe passes through the side of the lid, a water pump is installed on the water pipe, and a water inlet connector is installed at the upper end of the water pipe; a water inlet channel is also included, located on the side of the base box and the expansion boxes, and connected to the water pipe; atomizing nozzles connected to the water inlet channel are installed inside the base box and the expansion boxes; a control unit is also installed on the lid to control the temperature and humidity inside the incubator.

[0004] However, during the cultivation process, the edible fungi clump together inside the container, resulting in poor ventilation for those in the middle section, which can easily lead to overheating. While the aforementioned patent uses liquid spraying to dissipate heat, frequent spraying when the fungi are not dehydrated can easily cause mold and rot, hindering their growth. Summary of the Invention

[0005] The purpose of this invention is to provide an edible fungus cultivation device with a watering mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a mushroom cultivation device with a watering mechanism is provided, comprising a box body, a door hinged to an opening on one side of the box body, and multiple layers of placement boxes for storing mushrooms inside the box body. The cultivation device also includes a water storage tank, a temporary storage tank, and infusion pipelines mounted on the box body; wherein:

[0007] The bottom of the temporary storage box is connected to a return pipe;

[0008] One end of the infusion pipeline is connected to a water storage tank, and the other end has multiple water outlets; some of the water outlets are connected to a temporary storage tank for delivering water to the temporary storage tank; the other water outlets are located at the bottom of the return pipe for watering edible fungi.

[0009] A closable assembly is provided between the return pipe and the outlet located at the bottom of the return pipe. The closable assembly is located between multiple placement boxes and has a closed state and an open state. In the closed state, the closable assembly guides the water at the outlet of the infusion pipeline to the edible fungi in the placement box. In the open state, the water in the temporary storage box flows into the infusion pipeline through the return pipe, so that the gas around the placement box is drawn into the infusion pipeline.

[0010] As a further improvement to this technical solution, the reflux tube is slidably connected to the temporary storage box; a temperature-sensitive drive component for driving the reflux tube to slide is provided between the plurality of placement boxes; the closable component switches between a closed state and an open state according to the sliding state of the reflux tube.

[0011] As a further improvement to this technical solution, the infusion pipeline includes a water pump with an inlet end connected to a water storage tank, an outlet end connected to a water pump with a water delivery pipe and a branch pipe, and multiple branch pipes connected to the top of the water delivery pipe.

[0012] Each of the branch pipes is located at the bottom of the return pipe.

[0013] As a further improvement to this technical solution, the diameter of the branch pipe is larger than the diameter of the return pipe.

[0014] As a further improvement to this technical solution, the closable component includes a connecting pipe whose bottom end communicates with the branch pipe, and a retaining ring fixedly disposed at the bottom of the return pipe and located inside the connecting pipe; wherein:

[0015] When the outer ring of the retaining ring contacts the inner ring of the connecting pipe, the connecting pipe is in a closed state;

[0016] The middle part of the connecting pipe expands outward to form a gap between it and the outer ring of the retaining ring when the retaining ring moves down, so that the connecting pipe is in an open state. The pressure at the bottom of the return pipe is used to draw the gas around the placement box into the connecting pipe through the gap.

[0017] The outer ring of the connecting pipe is provided with multiple spray holes.

[0018] As a further improvement to this technical solution, the spray hole is set on the inclined surface at the top of the connecting pipe so that the water in the connecting pipe is sprayed out to the edible fungi in an upward tilting manner.

[0019] As a further improvement to this technical solution, the temperature-sensing drive component is a memory spring whose bottom end is connected to the connecting pipe and whose top end is connected to the return pipe. The memory spring is in an elongated state at room temperature to drive the return pipe upward, and in a compressed state above room temperature to drive the return pipe downward.

[0020] As a further improvement to this technical solution, the temperature-sensing drive includes a temperature sensor, a controller, and a cylinder. The temperature sensor is installed between multiple placement boxes to detect the temperature between the multiple placement boxes. The cylinder is disposed between the connecting pipe and the return pipe, and the controller controls the cylinder according to the temperature measured by the temperature sensor.

[0021] As a further improvement to this technical solution, the reflux pipe slides into the interior of the temporary storage box from the bottom. A plug is fixedly installed on the inner wall of the bottom of the temporary storage box, located directly above the reflux pipe. The reflux pipe engages with the plug during its upward movement, thereby sealing the top of the reflux pipe.

[0022] As a further improvement to this technical solution, the temporary storage box is located at the top of the box body; a piston plate is longitudinally slidably arranged inside the temporary storage box, and a compression spring is provided between the top of the piston plate and the inner wall of the top of the temporary storage box to elastically connect the two; a one-way valve is provided inside the diversion pipe, and the connection between the diversion pipe and the temporary storage box is located below the piston plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In this edible mushroom cultivation device with a watering mechanism, a closable component is installed between multiple placement boxes. When watering is needed, water in the infusion pipeline is discharged to the edible mushrooms through the closable component. When the edible mushrooms in the middle are overheated, water in the temporary storage box flows into the infusion pipeline through the return pipe and draws in the gas around the edible mushrooms during the flow, thus achieving forced ventilation and avoiding the need to cool the edible mushrooms by spraying water.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Please see Figure 1 As shown, an edible fungus cultivation device with a watering mechanism is provided, including a box body 100, and a door 101 hinged to an opening on one side of the box body 100 for opening or closing the box body 100. Figure 2 As shown, the box 100 has two layers of support racks 102 inside. Each layer of support racks 102 has multiple placement boxes 103 for loading edible fungi on its top. The edible fungi are covered with culture bags, and the bagged edible fungi are placed into the placement boxes 103.

[0044] During cultivation, the edible fungi in the container 100 tend to cluster together, leading to poor ventilation for the fungi in the middle section and increasing the risk of overheating. Therefore, if... Figure 2As shown, the cultivation device also includes a water storage tank 110 located at the bottom of the box 100, a temporary storage tank 120 located at the top of the box 100, and an infusion pipeline; wherein, the bottom of the temporary storage tank 120 is connected to a return pipe 121; one end of the infusion pipeline is connected to the water storage tank 110, and the other end has multiple water outlets, some of which are connected to the temporary storage tank 120 for delivering water to the temporary storage tank 120; the other part of the water outlets are located at the bottom of the return pipe 121 for watering the edible fungi; then, the return pipe 121 is connected to the water storage tank 110 located at the bottom of the box 100, and a temporary storage tank 120 located at the top of the box 100, and an infusion pipeline; wherein, the bottom of the temporary storage tank 120 is connected to a return pipe 121 for watering the edible fungi; then, the return pipe 121 is connected to the water storage tank 110 located at the bottom of the box 100, and a temporary storage tank 120 located at the top of the box 100, and an infusion pipeline 121 located at the bottom of the box 100, and a return pipe ... A closable component 130 is provided between the water outlets at the bottom of 21. The closable component 130 is located between multiple placement boxes 103 and has a closed state and an open state. In the closed state, the closable component 130 guides the water at the outlet of the infusion pipeline to the edible fungi in the placement box 103. In the open state, the water in the temporary storage box 120 flows into the infusion pipeline through the return pipe 121, so that the gas around the placement box 103 is drawn into the infusion pipeline, thereby improving the air circulation efficiency around the placement box 103.

[0045] Among them, combined Figure 5 The return pipe 121 is slidably connected to the temporary storage box 120. A temperature-sensitive drive 150 is provided between multiple placement boxes 103 to drive the return pipe 121 to slide. The closable component 130 switches between closed and open states according to the sliding state of the return pipe 121.

[0046] In other words, by setting a closable component 130 between multiple placement boxes 103, when watering is needed, the water in the infusion pipeline is discharged to the edible fungi through the closable component 130 under the guidance of the closable component 130; when the edible fungi in the middle are overheated, the water in the temporary storage box 120 flows into the infusion pipeline through the return pipe 121, and draws in the gas around the edible fungi during the flow, thus achieving forced ventilation and avoiding the need to cool the edible fungi by spraying water.

[0047] like Figure 2 As shown, the infusion pipeline includes an inlet connected to a water storage tank 110, and an outlet connected to a water pump 140 with a water delivery pipe 141 and a branch pipe 142. Multiple branch pipes 143 are connected to the top of the water delivery pipe 141. Then, as... Figure 3 As shown, each branch pipe 143 is provided at the bottom of the return pipe 121. Furthermore, the diameter of the branch pipe 143 is larger than the diameter of the return pipe 121 to increase the flow speed of the water flowing out from the bottom of the return pipe 121 within the branch pipe 143.

[0048] Thus, when water flows out of the return pipe 121 from the storage tank 120, the pressure at the bottom of the storage tank 120 begins to decrease, drawing in surrounding gas and allowing for rapid gas circulation in that area. However, when the branch pipe 143 remains open between it and the storage tank 120, the water in the branch pipe 143 cannot diffuse outwards during the drainage process, making it difficult to evenly water the edible fungi. Therefore, as... Figure 4 and Figure 5 As shown, a closable assembly 130 is provided between the return pipe 121 and the branch pipe 143, and the closable assembly 130 is located among multiple placement boxes 103. Figures 8-10 In the closure assembly 130, there is a connecting pipe 131 whose bottom end communicates with the branch pipe 143, and a retaining ring 132 fixedly disposed at the bottom of the return pipe 121 and located inside the connecting pipe 131. When the outer ring of the retaining ring 132 contacts the inner ring of the connecting pipe 131, the connecting pipe 131 is in a closed state. Simultaneously, the middle part of the connecting pipe 131 expands outward to form a gap between itself and the outer ring of the retaining ring 132 when the retaining ring 132 moves downward, thus opening the connecting pipe 131. This allows the pressure at the bottom of the return pipe 121 to push away the gas surrounding the placement box 103 when water is discharged through the return pipe 121. The water is drawn into the connecting pipe 131 through the gap and then discharged into the branch pipe 143. At the same time, the outer ring of the connecting pipe 131 is provided with multiple spray holes 133. The spray holes 133 are preferably located on the inclined surface at the top of the connecting pipe 131 (that is, the connection between the expansion part of the connecting pipe 131 and the bottom end of the connecting pipe 131). Under the action of the inclined surface, the spray holes 133 are inclined as a whole, so that the water in the connecting pipe 131 is sprayed out in an upward inclined manner. In addition, an atomizing nozzle can also be installed in the spray hole 133. When paired with the atomizing nozzle, the liquid discharged through the spray hole 133 is in the form of a mist, which facilitates the even watering of edible fungi.

[0049] When the placement box 103 is configured with multiple layers, the position between the branch pipe 143 and the return pipe 121 should be referenced. Figure 3 As shown in the figure, the bottom end of a portion of the return pipe 121 is located above the top support frame 102, and the top of the corresponding branch pipe 143 passes through the top support frame 102 and is located at the bottom of the return pipe 121; the bottom end of another portion of the return pipe 121 is located above the bottom support frame 102, and the top of the corresponding branch pipe 143 passes through the bottom support frame 102 and is located at the bottom of the return pipe 121, thereby enabling each layer to be equipped with a closable component 130.

[0050] In the above, a temperature-sensitive actuator 150 is provided between the multiple placement boxes 103 to drive the reflux pipe 121 to slide. The temperature-sensitive actuator 150 can control the sliding of the reflux pipe 121 according to the temperature of the edible fungi, thereby switching the closed and open states of the closable component 130 after controlling the sliding of the reflux pipe 121. For this purpose, as Figure 8 and Figure 9 As shown, in some embodiments, the temperature-sensing actuator 150 is a memory spring 151 whose bottom end is connected to the connecting pipe 131 and whose top end is connected to the return pipe 121. Specifically, both the top and bottom ends of the memory spring 151 are connected to mounting plates. Of the two mounting plates, one is fixed to the top of the connecting pipe 131 and the other is fixed to the outer ring of the return pipe 121. The memory spring 151 is in an elongated state at room temperature and in a compressed state above room temperature. Thus, since the connecting pipe 131 is located among multiple placement boxes 103, and the memory spring 151 is located at the memory spring 151, when the edible fungi in the placement box 103 reach a high temperature, the memory spring 151 will also be heated and become compressed. At this time, the memory spring 151 compresses and pulls the return pipe 121 downward, and the return pipe 121 drives the retaining ring 132 downward, so that a gap is formed between the retaining ring 132 and the connecting pipe 131.

[0051] To meet the requirements of high-precision temperature control, in some embodiments, the temperature sensing actuator 150 can employ a higher-precision temperature sensor, controller, and cylinder. For example, a temperature sensor is installed between multiple placement boxes 103 to detect the temperature between them. A cylinder is then positioned between the connecting pipe 131 and the return pipe 121, with the cylinder's position referencing the location of the memory spring 151. The controller then controls the cylinder based on the temperature measured by the temperature sensor. When the temperature rises, the controller activates the cylinder, causing the return pipe 121 to move downwards, creating a gap between the retaining ring 132 and the connecting pipe 131. When the high temperature dissipates, the controller activates the cylinder, causing the return pipe 121 to move upwards, sealing the gap with the retaining ring 132.

[0052] When the return pipe 121 is lowered, the water in the temporary storage tank 120 needs to be drained through the return pipe 121. Therefore, as follows... Figure 6 As shown and Figure 7As shown, the top of the reflux pipe 121 slides into the storage tank 120 from the bottom. A plug 126 is fixedly installed on the inner wall of the bottom of the storage tank 120, located directly above the reflux pipe 121. The bottom end of the plug 126 is preferably conical to seal the top of the reflux pipe 121. Thus, when the reflux pipe 121 moves upward, the plug 126 will be inserted into the opening at the top of the reflux pipe 121, at which point the top of the reflux pipe 121 is sealed. When the reflux pipe 121 moves downward, the opening at the top of the reflux pipe 121 disengages from the plug 126, and the liquid in the storage tank 120 can flow out through the reflux pipe 121.

[0053] Combination Figure 9 and Figure 10 As shown, the working principle of this invention is as follows:

[0054] When watering edible fungi, the water pump 140 is started. At this time, the water pump 140 delivers water from the water storage tank 110 to the temporary storage tank 120 through the diversion pipe 142, and delivers water to the branch pipe 143 through the water delivery pipe 141. At this time, the water in the branch pipe 143 is discharged into the connecting pipe 131 through the top of the branch pipe 143. However, since the top of the connecting pipe 131 is blocked by the retaining ring 132 and the top of the return pipe 121 is blocked by the plug 126, the water in the connecting pipe 131 can only be discharged through the spray hole 133. The water discharged through the spray hole 133 spreads to the edible fungi on the outward side, thus realizing the watering of edible fungi.

[0055] When the edible fungi overheat, the temperature-sensing actuator 150 located at the top of the connecting pipe 131 will cause the return pipe 121 to move downwards. At this time, the return pipe 121 will cause the retaining ring 132 to move downwards, creating a gap between the outer ring of the retaining ring 132 and the inner ring of the spray hole 133. Simultaneously, the return pipe 121 moves downwards and disengages from the plug 126. At this time, the water in the temporary storage tank 120 is discharged through the return pipe 121. The water discharged through the return pipe 121 flows into the branch pipe 143, and then flows back to the water supply pipe 141 through the branch pipe 143, and finally flows back to the water storage tank 110 through the water supply pipe 141. There are two ways for the water to flow back to the water storage tank 110: one is that the water in the water supply pipe 141 flows back to the water storage tank 110 after being pumped by the water pump 140; the other is that the end of the water supply pipe 141 is connected to the water storage tank 110 through a guide pipe (such as...). Figure 3 The water supply pipe 141 is connected to the branch pipe 143 at one end. The diameter of the guide pipe is smaller than that of the water supply pipe 141 (to prevent water from being unable to be transported to the branch pipe 143 when the water pump 140 is supplying water). At this time, the water in the water supply pipe 141 can flow back to the water storage tank 110 through the guide pipe.

[0056] As water flows out from the bottom of the return pipe 121, it forces the pressure at the bottom of the return pipe 121 to decrease, forcing the air around the outer periphery of the connecting pipe 131 (that is, around the placement box 103) to be drawn into the connecting pipe 131 through the gap, thereby realizing the flow of air around the placement box 103 and forcing the air circulation in the middle part to avoid the edible fungi in the middle part from overheating.

[0057] Furthermore, in order to further reduce the suction at the bottom of the return pipe 121, such as... Figure 6 As shown, a piston plate 122 is longitudinally slidably disposed inside the temporary storage box 120. A round rod 123 is fixedly disposed on the top of the piston plate 122, sliding through the top of the temporary storage box 120. A compression spring 124 is disposed between the top of the piston plate 122 and the inner wall of the top of the temporary storage box 120, elastically connecting the two. Furthermore, a one-way valve 125 is disposed inside the diversion pipe 142, and the connection between the diversion pipe 142 and the temporary storage box 120 is located below the piston plate 122.

[0058] The one-way valve 125 only allows water to enter the temporary storage tank 120. When the water pump 140 delivers water to the temporary storage tank 120 through the diversion pipe 142, the piston plate 122 is squeezed by the water and moves upward. At this time, the compression spring 124 is in a compressed state. When the return pipe 121 moves downward, the return pipe 121 disengages from the plug 126. At this time, the water in the temporary storage tank 120 is discharged through the return pipe 121. During this process, the compressed spring 124 rebounds and applies a pushing force to the water inside the temporary storage tank 120 through the piston plate 122, forcing the water to flow faster in the return pipe 121. As a result, when the water flows out from the bottom of the return pipe 121, the pressure at the bottom of the return pipe 121 is further reduced, which further improves the suction effect.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
