Description

Technical Field

[0001] The utility model belongs to the technical field of differential pressure inoculation, and specifically relates to a simple inoculation differential pressure bottle. Background Art

[0002] In the process of fermentation production, the strains prepared in the laboratory need to be first inoculated into an inoculation bottle and then transferred into a fermentation tank for cultivation. Existing inoculation bottles are mostly made of glass. Due to the poor pressure-bearing capacity of the glass material, it is extremely easy to collide with other equipment during use and cause breakage, especially when inoculating by the differential pressure method, the bottle is likely to explode, seriously affecting the safety of the fermentation production process; a small number of inoculation bottles are made of stainless steel, but since stainless steel is opaque, internal ultraviolet sterilization cannot be achieved, and it is not convenient for staff to observe, so the current inoculation bottles are still mainly made of glass.

[0003] Existing inoculation bottles mainly include a bottle body, a bottle stopper and an inoculation needle. When assembled, the bottle stopper is inserted into the bottle mouth of the bottle body, the inoculation needle is installed on the bottle stopper, and a through hole communicating with the inoculation needle and the bottle body is opened on the bottle stopper. During use, when the bottle stopper is plugged into the bottle mouth, since the bottle stopper and the bottle body of the inoculation bottle cannot form an effective unified body, there may be risks of the strains in the inoculation bottle running, overflowing, dripping, leaking and being contaminated when pressurizing the bottle. In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a simple inoculation differential pressure bottle that can overcome or at least partially solve the above problems.

[0006] In order to facilitate the operator to observe the situation of the strains in the inoculation bottle, and at the same time facilitate the inoculation bottle to maintain a transparent state for ultraviolet sterilization treatment of its interior, further, the protective shell is a transparent shell.

[0007] In order to facilitate providing good protection for the inoculation bottle without affecting the overall weight of the inoculation bottle, further, both the base and the protective shell are plastic shells.

[0008] In order to facilitate the operator to move the inoculation bottle more conveniently, further, a handle is fixedly connected to the protective shell.

[0009] In order to further improve the sealing performance of the plugging of the bottle mouth of the inoculation bottle, further, a rubber frustum is integrally connected to the cylindrical bottle plug, and the fixing plate is fixedly connected to the rubber frustum.

[0010] In order to avoid the problem of loss of the locking nut, further, the locking nut is rotatably connected to a position near the through hole at the upper end of the fixing plate.

[0011] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: By the cooperation of components such as the protective shell, the base, the fixing plate, the screw rod and the locking nut, the present utility model can not only make the cylindrical bottle plug be inserted into the bottle mouth of the inoculation bottle more tightly and stably, avoid the risk of the bacteria in the inoculation bottle running, leaking, dripping and oozing from the bottle mouth when pressurizing the bottle, but also play a protective role for the inoculation bottle, avoid the problems that the inoculation bottle is broken due to collision and the inoculation bottle explodes due to pressure and causes harm to the staff, and effectively improves the safety of the inoculation differential pressure bottle.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0019] Embodiment 1:

[0020] Referring to Figures 1 - 3 , a simple inoculation differential pressure bottle includes an inoculation bottle 1, a cylindrical bottle stopper 2 is inserted at the mouth of the inoculation bottle 1, and further includes: a fixing plate 3 connected to the upper end of the cylindrical bottle stopper 2; through holes 4 that are mutually circular are provided at the central positions of the cylindrical bottle stopper 2 and the fixing plate 3; an inoculation needle 5 is fixedly connected to the fixing plate 3 and communicates with the through hole 4 on the fixing plate 3; two protective shells 6 used in cooperation are clamped on the outside of the inoculation bottle 1; a base 7 is threadedly connected to the bottoms of the two protective shells 6; screw rods 601 are symmetrically arranged on one side adjacent to the two protective shells 6, and the two screw rods 601 are respectively located on both sides of the cylindrical bottle stopper 2; the screw rod 601 includes two semi-circular threaded rods, and the two semi-circular threaded rods are respectively fixedly connected to the two protective shells 6; a through port for cooperating with the screw rod 601 is provided on the fixing plate 3, and a locking nut 301 is threadedly connected to the screw rod 601.

[0021] When it is necessary to use this inoculation differential pressure bottle for differential pressure inoculation, the operator first disinfects and sterilizes all components of this inoculation differential pressure bottle, then clamps the two protective shells 6 on the outside of the inoculation bottle 1, and then connects the two protective shells 6 through the base 7 to fix them on the inoculation bottle 1. Then, the strain liquid can be added into the inoculation bottle 1, and then the cylindrical bottle stopper 2 is inserted into the mouth of the inoculation bottle 1 through the fixing plate 3. When the cylindrical bottle stopper 2 seals the mouth of the inoculation bottle 1, the two adjacent semi-circular threaded rods on the two protective shells 6 are passed through the through ports on the same side of the fixing plate 3 together, and then the two semi-circular threaded rods can form a complete screw rod 601. Then, a locking nut 301 is threadedly connected to the screw rod 601 until the locking nut 301 is closely attached to the fixing plate 3, and the cylindrical bottle stopper 2 can be tightly plugged into the mouth of the inoculation bottle 1. At the same time, the two protective shells 6 can also be firmly fixed on the inoculation bottle 1. After all operations are completed, the inoculation needle 5 can be inserted into the fermentation tank at this time, and then the inoculation operation can be carried out by the differential pressure method.

[0022] By the combined use of components such as the protective shell 6, the base 7, the fixing plate 3, the lead screw 601 and the locking nut 301, not only can the cylindrical bottle stopper 2 be inserted more tightly and stably into the bottle mouth of the inoculation bottle 1, avoiding the risk of the bacteria in the inoculation bottle 1 leaking, running, dripping or oozing out from the bottle mouth when pressurizing the bottle, but also it can play a protective role for the inoculation bottle 1, avoiding the problems that the inoculation bottle 1 is broken due to collision and the inoculation bottle 1 explodes due to pressure, causing harm to the staff, effectively improving the safety of the inoculation differential pressure bottle.

[0023] Example 2:

[0024] Refer to Figures 1 - 3 , a simple inoculation differential pressure bottle, which is basically the same as Example 1. Further: the protective shell 6 is a transparent shell. By making the protective shell 6 made of transparent material, it is not only convenient for the operator to observe the situation of the bacteria in the inoculation bottle 1, but also can keep the inoculation bottle 1 in a transparent state for ultraviolet sterilization treatment of its interior.

[0025] Both the base 7 and the protective shell 6 are plastic shells. By making both the base 7 and the protective shell 6 made of plastic, when installing the protective shell 6 on the inoculation bottle 1, the weight added to the inoculation bottle 1 by the protective shell 6 can be reduced, so that while not affecting the overall weight of the inoculation bottle 1, it can also play a good protective effect on the inoculation bottle 1.

[0026] A handle 602 is fixedly connected to the protective shell 6. By installing handles 602 on both protective shells 6, when it is necessary to lift and invert the inoculation bottle 1, the operator can lift the inoculation bottle 1 through the handle 602, thus facilitating the operator to move the inoculation bottle 1 more conveniently and providing convenience for the entire inoculation operation.

[0027] Example 3:

[0028] Refer to Figures 1 - 3 , a simple inoculation differential pressure bottle, which is basically the same as Example 2. Further: a rubber conical frustum 201 is integrally connected to the cylindrical bottle stopper 2, and the fixing plate 3 is fixedly connected to the rubber conical frustum 201. Through the setting of the rubber conical frustum 201, when the fixing plate 3 drives the cylindrical bottle stopper 2 to be inserted into the bottle mouth of the inoculation bottle 1, by continuously driving the cylindrical bottle stopper 2 to move downward, the rubber conical frustum 201 can tightly abut against the bottle mouth of the inoculation bottle 1, thereby further improving the sealing performance of the plugging of the bottle mouth of the inoculation bottle 1 and further reducing the risk of the bacteria in the inoculation bottle 1 leaking, running, dripping or oozing out and getting contaminated.

[0029] The locking nut 301 is rotatably connected to the upper end of the fixing plate 3 near the through hole. By connecting the locking nut 301 to the fixing plate 3, when it is necessary to remove the cylindrical stopper 2 and disassemble the lead screw 601 from the fixing plate 3, the locking nut 301 can always be located on the fixing plate 3, thereby avoiding the problem of loss of the locking nut 301.

[0030] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
