Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation device for a bacteria culture room. Background Art

[0002] Fungi are a large class of heterotrophic organisms that do not contain chlorophyll and cannot carry out photosynthesis. They have no differentiation of roots, stems and leaves, do not contain photosynthetic pigments such as chlorophyll (except for a very small number of photosynthetic bacteria), cannot carry out photosynthesis, live a saprophytic or parasitic life, that is, a heterotrophic life. Their reproductive organs are mostly single-cell structures, and the zygote does not develop into an embryo. As the demand for fungi increases, the development of culture rooms is also very critical.

[0003] With the rapid development of culture rooms, ventilation requirements for culture rooms have also increased. However, existing ventilation devices, such as a high-efficiency motor ventilation device disclosed in Chinese patent publication No. CN218678724U, have a fixed ventilation angle, resulting in a small ventilation range. The small ventilation range directly affects the normal ventilation efficiency and quality. Utility Model Content

[0004] The utility model provides a ventilation device for a culture room, which solves the problem of a fixed ventilation angle in the existing ventilation device, resulting in a small ventilation range, which directly affects the normal ventilation efficiency and quality.

[0007] Preferably, the bottom end of the adjusting screw is fixedly connected to a control knob.

[0008] Preferably, the top of the base plate is fixedly connected to two stabilizing tubes located on both sides of the mounting U-shaped plate, and the bottom of the combining plate is fixedly connected to stabilizing rods located above the two stabilizing tubes respectively, and the bottom ends of the stabilizing rods are slidably connected to the inner surfaces of the stabilizing tubes.

[0009] Preferably, both sides of the stabilizing tube are fixedly connected with reinforcement rods, and one end of the reinforcement rod away from the stabilizing tube is fixedly connected to the top of the base plate.

[0010] Preferably, the number of the spiral blades on the same vertical plane is no less than five, and no less than five of the spiral blades are arranged in a circular array.
