[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1:

[0052] The present invention provides Figure 1 The storage device for microbial inoculants shown in the figure includes a strong / negative pressure tank body 1, a detachable upper handle shell 2 movably provided on the outer side of the top end of the strong / negative pressure tank body 1, a detachable lower storage seat 3 movably provided on the outer side of the bottom end of the strong / negative pressure tank body 1, and a detachable pressure relief seal 4 movably provided at the center of the top end of the strong / negative pressure tank body 1;

[0053] like Figure 3-5 The strong / negative pressure tank body 1 includes a main tank 11, a tank mouth 12 is provided at the top of the main tank 11, and a thread is provided on the inner wall of the tank mouth 12. A plurality of wrinkle stacking convex patterns 13 are evenly arranged in the middle of the main tank 11, wherein the spacing between adjacent wrinkle stacking convex patterns 13 is not greater than 40 mm, and the height of the wrinkle stacking convex patterns 13 is not less than 0.5 mm. The wrinkle stacking convex patterns 13 are designed to be wrinkled corrugated. They are integrally injection molded with the main tank 11 and are made of dark brown PE material to reduce light transmittance, prevent ultraviolet rays from damaging the effective components of the microbial agent, avoid their decomposition or loss of activity, thereby protecting the effective components of the microbial agent from the influence of light and extending their shelf life. An air nozzle 14 and an air pressure gauge 15 are also provided at the top of the outer wall of the main tank 11. An anti-fouling component 16 is also fixedly provided on the inner wall of the tank 11; the anti-fouling component 16 includes a folding edge 161, an inner side of the folding edge 161 is provided with a mounting folding groove 162, and a protective ring 163 is movably installed inside the mounting folding groove 162; the inner diameter of the mounting folding groove 162 is smaller than the inner diameter of the folding edge 161, and the cross-sectional shape of the mounting folding groove 162 is set to be 1 / 2 circular, and the cross-sectional shape of the folding edge 161 is set to be 1 / 4 circular, and the mounting folding groove 162 and one end of the folding edge 161 are fixedly connected to the inner wall of the main tank 11, and a plurality of guide grooves 164 are evenly opened on the outer edge of the folding edge 161, and the setting of the folding edge 161 can play a certain shielding effect, effectively preventing the protective ring 163 from being contaminated when the high / negative pressure tank body 1 containing the microbial inoculant is slightly shaken;

[0054] like Figure 6 The protective ring 163 includes an inner core ring 002, and the inner core ring 002 is wrapped with a protective gasket ring 001; the protective gasket ring 001 is made of medical-grade sponge, and the inner core ring 002 is pressed and formed by carbon powder; the outer diameter of the protective gasket ring 001 is equal to the inner diameter of the installation groove 162;

[0055] like Figure 9 The pressure relief seal 4 includes a tank cover body I 41, a locking thread I 42 is provided at the bottom end of the tank cover body I 41, and the tank cover body I 41 is threadedly connected to the tank mouth 12 through the locking thread I 42; a press-type spring plug 43 (similar to the press-type pouring port of a thermos) is provided at the center of the tank cover body I 41, and a sealing gasket is also provided at the connection between the tank cover body I 41 and the tank mouth 12;

[0056] like Figure 7-8 The upper hand-held shell 2 includes an upper shell 21, a locking ring 22 is provided inside the upper shell 21, and a plurality of fixing wedges are fixed in a ring array between the outer edge of the locking ring 22 and the upper shell 21. The upper shell 21, the fixing wedges and the locking ring 22 are integrally injection-molded, and the inner wall of the upper shell 21 is provided with an internal thread that is threadedly connected to the top of the outer wall of the main tank 11; the locking ring 22 is locked with the tank mouth 12, and a plurality of hand-held grooves 23 are provided on the outer edge of the top of the upper shell 21; the lower placement seat 3 includes a lower seat shell 31, and a locking thread III 32 is provided on the inner wall of the lower seat shell 31. The lower seat shell 31 is threadedly connected to the outer wall of the bottom end of the main tank 11 through the locking thread III 32;

[0057] The specific implementation method is as follows: when using the device, first connect the upper handle shell 2 and the lower placement seat 3 to the outer wall of the top and bottom ends of the main tank 11 through corresponding threads, wherein the corresponding locking ring 22 of the upper handle shell 2 is aligned and locked with the tank mouth 12 to complete the preliminary assembly;

[0058] Then, the microbial agent to be stored is injected into the main tank 11 through the tank opening 12 for storage, and the pressure relief seal 4 is threadedly connected to the tank opening 12 through the locking thread I 42, and the push-type spring plug 43 is pressed to complete the locking and sealing at this location;

[0059] Then, according to the characteristics of the bacterial agent, the sealed cavity of the main tank 11 is vacuum-extracted or a certain amount of carbon dioxide or nitrogen is injected into the main tank 11 through the gas nozzle 14, and the air pressure value / vacuum value in the cavity of the main tank 11 is checked through the pressure gauge 15 to avoid damage to the main tank 11 caused by excessive pressure difference;

[0060] During the storage of the microbial inoculant in the strong / negative pressure tank body 1, the corrugated stacked ridges 13 on the outer wall disperse the stress of the main tank body 11, improve the longitudinal compressive strength of the main tank body 11, and prevent the main tank body 11 from being deformed or ruptured when subjected to external force or when the internal and external air pressure values ​​are too large, effectively preventing the main tank body 11 from expanding and rupturing. In addition, the upper handle shell 2 and the lower placement seat 3 are used to strengthen the protection of the top and bottom parts of the strong / negative pressure tank body 1 where the corrugated stacked ridges 13 are not provided (equivalent to thickened physical protection). Therefore, the strong / negative pressure resistance of the overall strong / negative pressure tank body 1 is improved. This effect can be achieved without excessively increasing the thickness of the strong / negative pressure tank body 1, reducing the overall weight, and thus facilitating single-person operation and taking by the user.

[0061] When the microbial agent is stored in the strong / negative pressure tank 1, the evaporation of water in the microbial agent may generate a small amount of water stains on the inner wall of the top of the main tank 11. The water stains flow down along the inner wall of the main tank 11 and can be trapped inside the installation groove 162 and absorbed by the protective gasket ring 001 corresponding to the protective ring 163, thereby preventing the water stains from flowing into the microbial agent again and causing activity disturbance and inactivation. In addition, when a large amount of carbon dioxide or nitrogen is injected into the strong / negative pressure tank 1, the small amount of oxygen retained can be absorbed by the inner core ring 002 made of carbon powder, thereby ensuring the storage environment and maintaining the activity of the anaerobic microbial agent.

[0062] The user can directly extract the strong / negative pressure tank body 1 containing the biological agent through the hand-held slot 23, move it to the place to be used, and then press the push-type spring plug 43 to release the seal to balance the internal and external air pressure, thereby facilitating the detachment of the pressure relief seal 4 and directly pouring the biological agent from the tank opening 12. During the pouring process, the biological agent liquid is limited and guided by the folding edge 161 and guided by the guide groove 164 to the position of the inverted main tank 11 corresponding to the tank opening 12, thereby preventing it from directly contacting the protective ring 163 and causing contamination. After the single storage operation is completed, the protective ring 163 can be replaced and installed at the tank opening 12 using a clip.

[0063] Example 2:

[0064] Based on the strong / negative pressure tank body 1 proposed in Example 1, the present invention provides a further technical solution for the pressure relief seal 4.
