[0001] This utility model relates to the field of black soldier fly farming technology, and in particular to a black soldier fly full life cycle demonstration teaching aid. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Strombidae*. They are highly adaptable to their environment, feeding on animal excrement, decaying organic matter, and plant waste. They have a diverse diet and are insensitive to oil, salt, garbage, and seasonings in their food. They consume large quantities, have a short lifespan, and are easy to raise. Furthermore, black soldier flies are not classified as agricultural or sanitary pests, possessing natural ecological safety and environmental friendliness.

[0003] Against the backdrop of continuous population growth and dwindling resources, insects like the black soldier fly, which can be transformed from waste into treasure, have enormous industrial potential. Therefore, universities often use the black soldier fly as a teaching case. The black soldier fly's life cycle generally goes through four stages: egg, larva, pupa, and adult. However, black soldier flies are scattered in nature, and understanding their life characteristics is costly and difficult, requiring significant investment of human, material, and financial resources. Consequently, students cannot gain a comprehensive understanding of the black soldier fly's habits and characteristics. Therefore, it is necessary to design a black soldier fly full life cycle demonstration teaching aid to simulate the natural environment, allowing students to more easily and intuitively understand the black soldier fly's habits and characteristics, and improving their observation and hands-on skills.

[0022] To better understand the purpose, function, and specific design of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of the black soldier fly full life cycle demonstration teaching aid of this utility model.

[0023] like Figure 1-4 As shown, the black soldier fly larvae full life cycle demonstration teaching aid of this utility model includes a shell 1, which includes a front 11, two sides 12, a rear 13, and a bottom 14. A buckle 2 is connected to the rear 13 of the shell 1, and a circulation system 3 is provided between the buckle 2 and the shell 1. The circulation system 3 can draw external air out of the shell 1 and exhaust the air inside the shell 1 to achieve air circulation within the shell 1. A breeding box 4 is provided at the bottom inside the shell 1 and is placed on the bottom 14. The breeding box 4 is used to feed and breed black soldier flies. A heating system is provided below the bottom 14 to control the temperature inside the shell 1. A top cover 6 is hinged to the top of the shell 1. The shell and the top cover 6 are connected by a pin. The end of the pin is provided with a retaining spring groove, and the pin is connected to the top cover 6 through the retaining spring. An observation port 7 is provided at the middle position of the front 11 of the shell 1 and the top cover 6, respectively. The growth process of black soldier flies in the breeding box 4 can be observed and recorded through the observation port 7. The observation port 7 is equipped with a detachable transparent plate.

[0024] Specifically, such as Figure 4 As shown, the breeding box 4 has two ramps 41 at different angles inside, which are used for black soldier flies to climb, allowing for the observation and recording of their climbing behavior through the observation port 7. The side walls of the breeding box 4 and the backs of the two ramps 41 form two grooves 42, which can hold water to increase the humidity inside the shell 1. A rotating cover 43 is hinged to the top of each of the two grooves 42. The rotation of the rotating cover 43 controls the brightness within the groove 42. Additionally, when the rotating cover 43 is rotated to an upright position, it can serve as a handle for the breeding box 4. Furthermore, the rotating design of the rotating cover 43 facilitates cleaning of the breeding box 4 and prevents it from obstructing view.

[0025] like Figure 1-3 As shown, the circulation system 3 includes a fan assembly 31, which is positioned above the buckle plate 2 and the housing 1. The fan assembly 31 is connected to the inside and outside of the housing 1 and is electrically connected to a fan button 32, which is located on the buckle plate 2 and controls the operating state of the fan assembly 31. An air inlet slot 21 is provided below the buckle plate 2, and multiple air inlets 15 are provided in the lower part of the housing 1. Preferably, a mesh 33 is provided at the position where the fan assembly 31 connects to the inside of the housing 1 to prevent black soldier flies from entering the fan assembly 31; a metal mesh 34 is provided at the position where the fan assembly 31 connects to the outside of the housing 1 to prevent the operator's hands or other tools from entering the fan assembly 31 and causing damage. It is worth noting that a deodorizing box 35 is also provided between the fan assembly 31 and the buckle plate 2 in this embodiment. When the air inside the housing 1 flows through the deodorizing box 35, it can remove odors mixed in with the air.

[0026] When the fan assembly 31 is started, the naturally flowing air from outside flows in through the air inlet slot 21 under the cover plate 2 due to the negative pressure inside the casing, and then enters through the small air inlet hole 15 at the bottom of the casing, passing through the mesh 33, the fan assembly 31, the deodorizing box 35 and the metal mesh 34 in sequence before flowing back to the outside atmosphere.

[0027] The heating system includes a heating plate. A base plate is detachably connected to the bottom surface 14 of the housing 1. The heating plate is positioned between the bottom surface 14 and the base plate. The heating plate is electrically connected to a heating button 5, which is mounted on a mounting plate 2. The heating button 5 controls the operating state of the heating plate. In this embodiment, the heating plate has three operating states with sequentially increasing temperatures, indicated by indicator lights of green, blue, and red.

[0028] Preferably, temperature and humidity sensors 8 are provided on both sides 12 of the housing 1 to adjust the working state of the heating plate according to the real-time temperature and humidity data.

[0029] It is worth noting that a battery 9 is provided between the buckle plate 2 and the housing 1 in this embodiment. The battery 9 can provide temporary power to the device in case of power outages or to take the teaching aid to a place without power for teaching.

[0030] When using this black soldier fly larvae demonstration and teaching aid for the first time, first open the top cover 6, take out the breeding box 4 inside, add materials and black soldier fly larvae to the center of the breeding box 4, add an appropriate amount of water to the grooves 42 on both sides of the breeding box 4, and after completing the above steps, put the breeding box 4 back into the outer shell, close the top cover 6, turn the fan button 32 to the start position, and start the circulation system 3. Press the heating button 5 to make it display green to start low-temperature heating, connect the power supply, and at the same time, charge the internal battery 9 while supplying power to the equipment to start breeding.

[0031] Observe the black soldier flies, materials, and water levels in the grooves 42 on both sides of the breeding box 4 daily through the transparent plate of the observation port 7. Replace the materials when they become dry, and manually add water by opening the top cover 6 when the water level in the grooves 42 is insufficient. After one week of breeding, when the black soldier flies have grown into older flies, it is no longer necessary to add water to the grooves 42. When the older flies are ready for breeding, open the rotating cover 43 to allow light to enter the grooves 42 on both sides of the breeding box 4, preventing a dark environment and thus preventing older flies from crawling into the grooves 42. Continue breeding for another month. As the black soldier flies inside the breeding box 4 gradually grow, their characteristics can be observed daily.

[0032] When the black soldier flies turn black, close the rotating cover 43. The black soldier flies will automatically crawl into the grooves 42 on both sides of the rearing box 4 and pupate in the grooves 42. During this time, open the top cover 6 and place the oviposition board inside. After pupation, the black soldier flies will automatically fly out of the grooves 42 and ascend to the space above the rearing box 4 to mate automatically. They will then lay their eggs on the oviposition board. After laying their eggs, the black soldier flies will automatically die a few days later. After the black soldier flies die, open the top cover 6, clean and remove the dead black soldier flies, remove the oviposition board, scrape off the eggs with a tool, place them back into the rearing box 4 for further rearing, and then close the top cover 6.

[0033] This utility model presents a black soldier fly larvae life cycle demonstration device with an ingenious structural design. Through the observation ports on the shell and top cover, it allows for direct observation and recording of the black soldier fly's life characteristics and habits, enabling exploration of its life features and continuous discovery of other advantages. Daily observation enhances students' recording and summarizing abilities, while operating the equipment improves their hands-on skills.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
