[0027] In this embodiment: by pressing the pressing block 501, the connecting block 502 and the first spring 503 are moved, releasing the fixing of the tank body 1, allowing the connecting ring 3 to be removed from the tank body 1, thereby allowing the top cover 2 to be removed, improving the flexibility of the fixing component 5. Then, by releasing the pressure applied to the pressing block 501, under the elastic action of the first spring 503, the pressing block 501 is driven back to its original position, causing the surface of the pressing block 501 to contact the inner wall of the positioning hole 11, thereby making the air filter connection more secure and improving the stability of the device.

Furthermore, by using the positioning hole 11 in conjunction with the pressing block 501, the surface of the pressing block 501 comes into contact with the inner wall of the positioning hole 11, which makes the top cover plate 2 more firmly connected and improves the stability of the device.

[0034] As a technical optimization of this utility model, the positioning block 4 has a moving groove 12 for use with the connecting block 502, and the side of the first spring 503 away from the connecting block 502 is fixedly connected to the inner wall of the moving groove 12. The side of the positioning block 4 away from the connecting block 502 has a pressing hole 13 for use with the pressing block 501, and the pressing hole 13 is connected to the moving groove 12.

[0035] In this embodiment: the pressing hole 13 is connected to the moving groove 12, so that the pressing block 501 can drive the connecting block 502 to move smoothly inside the moving groove 12, thereby releasing the fixing work on the tank body 1 and allowing the top cover plate 2 to be removed. Under the elastic action of the first spring 503, the connecting block 502 can drive the pressing block 501 to return smoothly to its original position under the restriction of the pressing hole 13, thereby fixing the top cover plate 2 and improving the flexibility of the fixing component 5.

[0036] As a technical optimization of this utility model, a rubber ring 14 is sleeved on the side of the connecting ring 3 away from the positioning block 4, and the surface of the rubber ring 14 is in contact with the inner wall of the tank 1.

[0037] In this embodiment: by using the rubber ring 14 in conjunction with the connecting ring 3, the surface of the rubber ring 14 comes into contact with the inner wall of the tank 1, which makes the connection between the connecting ring 3 and the tank 1 more secure, avoids air leakage, and improves the sealing performance of the device.

[0038] As a technical optimization of this utility model, both sides of the inner wall of the tank body 1 are provided with slide grooves 15 for use with the slider 801, and the side of the second spring 803 away from the slider 801 is fixedly connected to the bottom of the inner wall of the slide groove 15.

Furthermore, under the elastic action of the second spring 803, the slider 801 can drive the support plate 802 to move, allowing the top of the filter element 9 to contact the bottom of the top cover plate 2, thereby fixing the filter element 9 of a certain specification and improving the flexibility of use of the fixing component 5.

[0040] As a technical optimization of this utility model, the top of the support plate 802 is provided with an installation hole 16 for use with the filter element 9, and the bottom surface of the filter element 9 is in contact with the inner wall of the installation hole 16.

[0041] In this embodiment: by using the filter element 9 in conjunction with the mounting hole 16, the bottom surface of the filter element 9 comes into contact with the inner wall of the mounting hole 16, which makes the filter element 9 more firmly connected, so that the filtered air can be discharged from the filter element 9 through the mounting hole 16, ensuring the normal progress of biological fermentation and improving the efficiency of biological fermentation.

[0042] Working principle: First, when filtering the air inside the factory, pressing the pressing block 501 moves the connecting block 502 and the first spring 503, releasing the fixing of the tank body 1 and allowing the connecting ring 3 to move out of the tank body 1. This allows the top cover 2 to be removed. Then, by releasing the pressure applied to the pressing block 501, the pressing block 501 returns to its original position under the elastic action of the first spring 503, making the surface of the pressing block 501 contact the inner wall of the positioning hole 11. This makes the air filter connection more secure. Furthermore, under the action of the rubber ring 14, the surface of the rubber ring 14 contacts the inner wall of the tank body 1, allowing the top cover 2 to be removed. The connection between the filter element 801 and the tank 1 is more secure, preventing air leakage. Under the elastic action of the second spring 803, the slider 801 moves smoothly under the restriction of the slide groove 15, driving the support plate 802 to move smoothly. This allows the top of the filter element 9 to contact the bottom of the top cover plate 2, thus fixing the filter element 9 of a certain specification. Under the action of the air inlet pipe 7, the outside air can enter the interior of the tank 1 smoothly. Then, through the cooperation of the filter element 9 and the mounting hole 16, the air flows smoothly out of the filter element 9, thus allowing the filtered air to be smoothly discharged from the tank 1, ensuring the normal progress of biological fermentation.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
