[0022] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0023] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand the advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0024] Embodiment 1

[0025] The utility model controls the connection or isolation between the inside and the outside of the fermentation device by arranging the first air inlet and the second air inlet, and draws the outside air into the fermentation device from the first air inlet and the second air inlet through the exhaust device. The fermentation device not only meets the requirement of full contact between the bacterial fertilizer and the air during the fungal experiment, but also maintains the sealing performance of the fermentation device.

[0026] like Figure 1-2 As shown, a small solid fermentation device for a biocontrol fungus laboratory comprises a casing 1 and a base 2 movably mounted at the bottom of the casing 1, and a suction device 3 movably mounted on the top of the casing 1. The base 2 comprises a bottom plate 21 and a clamping portion 22. The maximum outer diameter of the bottom plate 21 is greater than the maximum outer diameter of the casing 1, which is convenient for disassembly.

[0027] The clamping part 22 is in the shape of a circular cylinder and is movably mounted on the bottom of the casing 1. The clamping part 22 is provided with at least one first air inlet hole 221. Figure 3 As shown, at least one second air inlet 11 is provided at the bottom of the casing 1, and the first air inlet 221 and the second air inlet 11 can be overlapped or staggered by rotating the base 2. A fermentation box 4 is provided on the base 2, and the fermentation box 4 is two fermentation covers 41 covering each other, and the bottom and side of the fermentation cover 41 are provided with a plurality of through holes, so that the bacterial fertilizer in the fermentation box 4 can be fully in contact with the air.

[0028] Furthermore, the air extraction device 3 includes a top cover 31, a threaded rod 32, and a polygonal plate 33 mounted on the threaded rod 32. The top cover 31 is rotatably mounted on the top of the casing 1. When the top cover 31 is rotated, the polygonal plate 33 moves up and down on the threaded rod 32. Figure 3As shown, further, a polygonal channel 12 is provided inside the casing 1, and the shape and size of the polygonal plate 33 are the same as those of the polygonal channel 12. The polygonal plate 33 fits tightly with the inner wall of the polygonal channel 12. Further, the bottom of the polygonal channel 12 is higher than the top of the fermentation box 4. This prevents the bottom of the casing 1 from being unable to be engaged with the base 2.

[0029] Furthermore, the bottom plate 21 is provided with at least three support rods 211 for placing the fermentation box 4. The fermentation box 4 can be directly placed on the three support rods 211, so that the bottom of the fermentation box 4 is separated from the bottom plate 21, and the bacterial fertilizer at the bottom of the fermentation box 4 can be fully in contact with the air.

[0030] Furthermore, a first annular clamping block 222 is disposed on the outer side of the clamping portion 22. Furthermore, a first annular groove 13 is disposed on the inner side of the bottom of the casing 1 and is clamped with the first annular clamping block 222.

[0031] like Figure 3 As shown, further, a second annular block 14 is provided on the outer side of the top of the casing 1. Further, a second annular groove 311 is provided on the inner side of the top cover 31 to be mutually engaged with the second annular block 14. Further, a limit block 321 is provided at the bottom of the threaded rod 32. The outer diameter of the limit block 321 is larger than the outer diameter of the threaded rod 32. This prevents the polygonal plate 33 from falling off when it moves downward.

[0032] Working principle:

[0033] Use your hands to separate the bottom plate 21 from the casing 1, then place the bacterial fertilizer on the two fermentation covers 41, and cover the two fermentation covers 41 with each other. Rotate the bottom plate 21 and the casing 1 so that the first air inlet 221 overlaps with the second air inlet 11. At this time, rotate the top cover 31, and the threaded rod 32 drives the polygonal plate 33 to rise in the polygonal channel 12. The space in the casing 1 becomes larger, the air pressure decreases, and the external air is sucked into the casing 1. Rotate the bottom plate 21 and the casing 1 again so that the first air inlet 221 is staggered with the second air inlet 11, and the internal and external environments of the casing 1 are isolated. A closed space is formed in the casing 1 to isolate it from external pollution.
