[0035] Embodiment

[0036] Referring to the accompanying drawings of the specification, as Figures 1-9 shown, a fermentation system intake device includes a container 1, a rotating fan 3 and an exhaust fan 2. An outlet pipe 12 and an intake pipe 11 are connected and arranged on the container 1. The container 1 intakes air through the intake pipe 11 and discharges the gas in the container 1 through the outlet pipe 12. The intake pipe 11 is horizontally distributed at the bottom of the container 1, and the outlet pipe 12 is vertically arranged at the top of the container 1. The number of intake pipes 11 is at least one, such as Figure 2As shown, multiple intake pipes 11 can supply gas to the container 1 simultaneously. A ventilation opening 121 is provided on the outlet pipe 12, and an exhaust fan 2 fixed to the top of the container 1 is connected to the ventilation opening 121. When the exhaust fan 2 operates, a negative pressure is formed at the bottom of the outlet pipe 12, and the gas in the container 1 enters the subsequent fermentation tank through the outlet pipe 12 for fermentation. The exhaust fan 2 is a known existing structure.

[0037] As Figures 6-9 shown, the rotating fan 3 includes multiple fan blades 31, a first frame 32, a second frame 33, a connecting rod 34, and an end cap 35. The shape of the fan blade 31 is an arc-shaped long strip; multiple fan blades 31 are circumferentially distributed around the connecting rod 34. Specifically, a limiting protrusion 341 is provided on the connecting rod 34, and the end cap 35 is connected to the end of the connecting rod 34 by a thread and can be disassembled. The position of the first frame 32 is limited between the limiting protrusion 341 and the end cap 35. The first frame 32 includes an outer ring 321 and an inner ring 322. The connecting rod 34 passes through the center of the inner ring 322, and the rotation of the first frame 32 and the connecting rod 34 is asynchronous, that is, the rotation of the connecting rod 34 and the rotation of the first frame 32 are independent of each other. Thus, by changing the diameter of the inner ring 322, the first frame 32 can move laterally along the connecting rod 34 during rotation. The edge of the second frame 33 is fixedly connected to the inner wall of the intake pipe 11. At least one through hole 331 is provided on the second frame 33. The connecting rod 34 passes through the center of the second frame 33 and rotates asynchronously with the second frame 33.

[0038] Based on the above structure, when the air flow enters from the intake pipe 11, it blows the fan blades 31 on the first frame 32 to make them rotate. During the rotation, the first frame 32 as a whole can move laterally along the connecting rod 34, so that the final movement trajectory of the first frame 32 is to swing while rotating. Therefore, the fluid area of the air flow in the intake pipe 11 expands after passing through the rotating fan 3, enabling the gas in the intake pipe 11 to diffuse into the space in the container 1 faster.

[0039] Furthermore, as Figure 9 shown, the second frame 33 includes multiple connecting bars 332, and the multiple connecting bars 332 are circumferentially distributed around the connecting rod 34. The connecting bars 332 can not only serve as the main body of the second frame 33, but also, due to their relatively narrow structure, can retain larger through holes 331 to ensure the inflow of air.

[0040] To disinfect the inflowing air and ensure that it contains fewer impurities. As Figure 4 shown, a disinfection layer 13 is provided on the inner wall of the container 1. Specifically, the disinfection layer 13 can be a silver oxide coating. Alternatively, multiple ultraviolet lamps 14 are provided at the bottom of the container 1.

[0041] In addition, to maintain the humidity of the air, as Figure 4 、Figure 5 As shown, an atomizer 4 is also provided. Specifically, the atomizer 4 is arranged on the air outlet pipe 12. The atomizer 4 is respectively connected with a water inlet 42 and a water outlet 41, and the water outlet 41 communicates with the inside of the air outlet pipe 12. The water inlet 42 is controlled by a second valve 43. Based on this, the air outlet pipe 12 can be a square pipe to facilitate the installation of the atomizer 4.

[0042] Embodiment 2

[0043] As Figure 10 shown, in this embodiment, the atomizer 4 is arranged at the top inside the container 1. Based on this, in order to avoid the atomizer 4 affecting the ultraviolet lamp 14, a partition 15 is also arranged on the inner wall of the container 1. The partition 15 is located below the atomizer 4, and the ultraviolet lamp 14 is located below the partition 15. A notch 151 is arranged at the center of the partition 15, and the air below the partition 15 is sucked to the top of the container 1 through the notch.

[0044] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
