[0002] The ventilation system of liquid spawn culture tanks for edible fungi is a key piece of equipment to ensure that the spawn grows in a suitable gaseous environment. It purifies the incoming air through a filtration device to prevent dust, bacteria, and other contaminants from entering the culture tank and contaminating the spawn. At the same time, it uses pipes and valves to precisely control the flow rate and timing of air intake and exhaust, and promptly removes metabolic waste gases such as carbon dioxide generated during the cultivation process.

[0003] Existing ventilation devices for edible fungi culture tanks commonly use bolts or complex clips to secure the filters during internal filter replacement. Bolts require individual tightening, which is time-consuming and labor-intensive. Furthermore, bolts are prone to rusting and stripping after prolonged use, further increasing the difficulty of disassembly. Additionally, special clips may require specialized tools or specific operating techniques, which can easily damage the clips if the user is unfamiliar with them, hindering the disassembly process. Therefore, we propose a ventilation device for liquid edible fungi culture tanks. Utility Model Content

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a ventilation device for a liquid culture tank for edible fungi, comprising: a ventilation box 1, an air inlet pipe 2 on the side surface of the ventilation box 1, an air outlet pipe 3 at the other end of the ventilation box 1 away from the air inlet pipe 2, a sealing cover 5 movably connected to the upper surface of the ventilation box 1, a pull handle 4 fixedly connected to the outer surface of the sealing cover 5, a quick-disassembly and installation replacement component 6 inside the ventilation box 1, and a rotation positioning limiting component 7 at the bottom of the replacement component 6.

[0027] When in use, by using the fixing bracket 61 and the limiting block 67 in the replacement component 6, the filter box 63 can be disassembled and replaced simply by opening the sealing cover 5 and pulling the pull block 64. This does not require any special tools or the tightening of multiple bolts, reducing reliance on tools and avoiding wasting time searching for or using tools.

[0028] Replacement component 6 includes a fixing frame 61, a base frame 62 movably connected to the bottom of the fixing frame 61, a filter box 63 movably connected inside the fixing frame 61, a pull block 64 fixedly connected to the side surface of the filter box 63, filter media 65 filled inside the filter box 63, a fixing plate 66 fixedly connected to the side surface of the filter box 63, a limit block 67 movably connected to the side surface of the fixing plate 66, a limit plate 68 fixedly connected to the outer surface of the limit block 67, a spring column 69 fixedly connected to the end of the limit plate 68 away from the limit block 67, and a support column 610 fixedly connected to the side surface of the spring column 69.

[0029] In use, first place the fixing frame 61 into the air exchange box 1, then place the filter media 65 to be filled into the filter box 63. Press the filter box 63 downwards along the side surface of the fixing frame 61. As the filter box 63 slides downwards, the inner wall of the fixing frame 61 will first squeeze the limiting block 67, causing the limiting block 67 to move into the fixing plate 66. When the filter box 63 is installed in the appropriate position, the spring column 69, through the limiting plate 68, pushes the limiting block 67, causing the limiting block 67 to abut against the inner wall of the fixing frame 61, so that the filter box 63 can be fixed inside the air exchange box 1. When it is necessary to replace the filter media 65 inside the filter box 63, pull the filter box 63 upwards by pulling the block 64, so that the filter box 63 can be quickly disassembled. The filter media 65 inside the filter box 63 can be replaced with different types according to the on-site usage environment, thereby meeting different production needs.

[0030] The spring column 69 is fixedly connected between the limiting plate 68 and the support column 610, and the upper and lower ends of the support column 610 are fixedly connected to the inner wall of the fixing plate 66.

[0031] During use, the spring column 69 ensures that the filter box 63 fits tightly against the fixing frame 61 after installation, effectively preventing unfiltered gas from entering the tank due to loose filter box 63, thus ensuring the airtightness of the ventilation device and providing a stable environment for the cultivation of edible fungi in liquid culture.

[0032] The limiting block 67 is slidably connected to the inner surface of the fixing frame 61. During use, the setting of the limiting block 67 and the spring column 69 makes the pressing method of the limiting block 67 less damaging to the filter box 63 during installation and disassembly compared to traditional bolt connections or other complex fixing methods. It will not cause deformation of the parts due to bolt rust, stripping, or over-tightening, and it is also less likely to damage other parts when using special tools for disassembly. This helps to extend the service life of the equipment. Secondly, it allows the filter box 63 to maintain good performance after multiple installations and disassemblies, making it easy to reuse and reducing maintenance costs.

[0033] The limiting component 7 includes a fixed base 71, a rotating shaft 72 is movably connected to the upper surface of the fixed base 71, a rotating plate 73 is fixedly connected to the outer surface of the rotating shaft 72, and a rotating handle 74 is fixedly connected to the upper surface of the rotating shaft 72.

[0034] When in use, the fixing bracket 61 is inserted into the gap of the base frame 62. The operator manually rotates the rotating handle 74, which drives the rotating shaft 72 to rotate. This rotates the rotating plate 73 to the bottom upper surface of the fixing bracket 61, thereby limiting and fixing the fixing bracket 61. This makes it easier, more efficient and thorough to clean the entire air exchange box 1 later. At the same time, the rotating plate 73 limits and fixes the fixing bracket by rotation, so that the size of the fixing bracket 61 can be changed according to different filtration indicators, thereby improving the applicability of the limiting component 7.
