[0002] Fermentation refers to the process of preparing the microbial cells themselves or direct metabolites or secondary metabolites by means of the life activities of microorganisms under aerobic or anaerobic conditions. Common fermentation refers to a certain decomposition process of organic matter by organisms. Fermentation is a biochemical reaction that humans have been exposed to for a long time. Emulsions are widely used in the food industry, biological and chemical industries.

[0003] The fermentation bottle is one of the most commonly used and simplest storage containers during fermentation, but its fermentation effect is not ideal because gas is produced during the fermentation process and needs to be discharged. If the bottle cap is opened to discharge the gas, it will affect the final fermentation effect, so it is urgently needed to be improved. Utility Model Content

[0004] The utility model aims to provide a gas outlet bottle cap for fermentation, so as to solve the problem in the above background technology that gas is generated during the fermentation process and needs to be discharged, and if the bottle cap is opened to discharge the gas, the final fermentation effect will be affected.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas venting bottle cap used for fermentation, comprising a bottle cap body, a concave cavity is arranged at the middle position of the bottle cap body, a convex edge is arranged at the edge position of the concave cavity, a card groove is opened inside the convex edge, a first sealing ring is vertically arranged at the outer edge of the convex edge, an exhaust groove is integrally formed on one side of the concave cavity, a first exhaust hole is opened at the center position of the bottom of the exhaust groove, an exhaust column is vertically fixed at the middle position inside the exhaust groove, and a second exhaust hole is opened on the side wall of the bottom end of the exhaust column.

[0006] Preferably, the height of the exhaust column is equal to the depth of the exhaust groove, ensuring the flatness of the cavity surface.

[0007] Preferably, the height of the bottom of the exhaust groove is greater than the height of the bottom end of the first sealing ring to avoid blocking the first exhaust hole when too much fermentation liquid is filled in the fermentation bottle.

[0008] Preferably, a second sealing ring is horizontally arranged at the bottom end of one side of the slot, and a connecting portion is arranged at the bottom of the other side of the slot, and the connecting portion is wavy, and the two ends of the connecting portion are respectively connected to the convex edge and the concave cavity. Since the bottle cap is made of injection molding of plastic material, the plastic material itself is elastic, and the connecting portion can be squeezed to deform during the process of the slot being connected to the top of the fermentation bottle, which can not only ensure the firmness of the assembly, but also ensure the sealing of the connection.

[0009] Preferably, the second sealing ring is symmetrically arranged with respect to the connecting portion.

[0010] Preferably, the first sealing ring, the convex edge and the concave cavity are integrally formed, and the bottle cap body is made of plastic.

[0011] Preferably, the second exhaust hole is communicated with the first exhaust hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) By providing an exhaust groove on the concave cavity, an exhaust column for assembling an S-shaped one-way exhaust valve for a fermentation barrel is vertically provided in the exhaust groove, so that the gas generated in the fermentation bottle can be discharged without opening the bottle cap, which is not only convenient to use but also can ensure the fermentation effect;

[0014] (2) By respectively arranging a second sealing ring and a wavy connecting portion on both sides of the interior of the slot, the second sealing ring and the connecting portion are symmetrically arranged, so that the mouth of the fermentation bottle inserted into the slot can be clamped, thereby ensuring the firmness and sealing of the assembly.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the utility model shall fall within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides an embodiment: a gas outlet bottle cap for fermentation, comprising a bottle cap body 1, a concave cavity 3 is arranged at the middle position of the bottle cap body 1, a convex edge 6 is arranged at the edge position of the concave cavity 3, a card groove 9 is opened inside the convex edge 6 for clamping with the edge of the bottle mouth of the fermentation bottle, a first sealing ring 2 is vertically arranged at the outer edge of the convex edge 6 for covering the outer wall of the top of the fermentation bottle to ensure the firmness of the assembly, and the first sealing ring 2, the convex edge 6 and the concave cavity 3 are integrally formed;

[0024] An exhaust groove 4 is integrally formed on one side of the concave cavity 3, a first exhaust hole 5 is provided at the center of the bottom of the exhaust groove 4, an exhaust column 7 is vertically fixed at the middle position inside the exhaust groove 4, a second exhaust hole 8 is provided on the side wall at the bottom end of the exhaust column 7, and an S-shaped one-way exhaust valve for a fermentation barrel is sleeved on the exhaust column 7 to exhaust the gas generated during the fermentation process in the fermentation bottle;

[0025] The second exhaust hole 8 is connected to the first exhaust hole 5;

[0026] The height of the exhaust column 7 is equal to the depth of the exhaust groove 4 to ensure the flatness of the surface of the cavity 3. The height of the bottom of the exhaust groove 4 is greater than the height of the bottom end of the first sealing ring 2 to avoid blocking the first exhaust hole 5 when too much fermentation liquid is filled in the fermentation bottle.

[0027] A second sealing ring 11 is horizontally arranged at the bottom end of one side of the slot 9, which is used to seal the outer edge of the top of the fermentation bottle. A connecting portion 10 is arranged at the bottom of the other side of the slot 9, and the connecting portion 10 is wavy. The second sealing ring 11 and the connecting portion 10 are symmetrically arranged. Since the bottle cap is made of injection molding of plastic material, the plastic material itself has elasticity. When the slot 9 is connected to the top of the fermentation bottle, the connecting portion 10 can be squeezed to deform, which can not only ensure the firmness of the assembly, but also ensure the sealing of the connection. The two ends of the connecting portion 10 are respectively connected to the convex edge 6 and the concave cavity 3.

[0028] When the embodiment of the present application is in use: first, the bottle cap body 1 is clamped on the fermentation bottle so that the clamping groove 9 is clamped at the bottle mouth of the fermentation bottle, and the bottle mouth of the fermentation bottle is clamped by the symmetrically arranged second sealing ring 11 and the connecting part 10. Since the bottle cap body 1 is made of injection molding of plastic material, the plastic material itself has elasticity. During the process of the clamping groove 9 being clamped on the top of the fermentation bottle, the connecting part 10 can be squeezed to deform, thereby ensuring that when the bottle mouth of the fermentation bottle is completely clamped in the clamping groove 9, the connecting part 10 is pressed against the inner wall of the bottle mouth, and the second sealing ring 11 is pressed against the outer wall of the bottle mouth, thereby ensuring the firmness and sealing of the assembly; then, the S-shaped one-way exhaust valve for the fermentation barrel is sleeved on the exhaust column 7, so that the gas generated in the fermentation bottle can be discharged without opening the bottle cap body 1.
