Description

Technical Field

[0001] This invention relates to the field of fermentation jar technology, and more particularly to an improved earthenware jar for fermenting sour soup. Background Technology

[0002] Sour soup, a traditional fermented food with distinctive characteristics in Southwest my country, has strict requirements for the air permeability, airtightness, and stability of the container during its fermentation process. Earthenware jars, due to their natural materials, excellent air permeability, and ability to form a positive interaction with the fermentation system, can promote the stable reproduction of beneficial microorganisms such as lactic acid bacteria in sour soup. For a long time, they have been the preferred container for sour soup fermentation and are widely used in home-made and small-scale workshop production. However, existing traditional earthenware jars for fermenting sour soup have poor stability during long-term use and are easily tipped over by external forces. Because the earthenware jars themselves are brittle and hard, tipping over not only causes damage to the jar and loss of the fermenting sour soup, but may also cause safety accidents such as cuts caused by broken earthenware fragments, resulting in economic losses and safety risks for users. At the same time, traditional earthenware jars have a protective film-like layer to prevent the entry of air, but the structure of this protective film is not very stable. After the jar is opened for the first time to fill materials or take out sour soup, the microporous structure of the protective film is prone to irreversible damage, and some areas may even be damaged or fall off, resulting in a significant reduction in its ability to prevent air from entering. After resealing, a large amount of outside air can easily seep into the jar, which will not only cause the sour soup to oxidize and deteriorate, but also breed putrefactive bacteria, seriously affecting the flavor, quality and shelf life of the sour soup. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a solution to the problem that existing traditional earthenware jars for fermenting sour soup have poor stability during long-term use and are easily damaged by tipping over due to external forces; another purpose of this invention is to provide a solution to the problem that the protective film-like structure on traditional earthenware jars has poor stability.

[0004] Technical solution: An improved earthenware jar for fermenting sour soup, comprising a jar body, a rim groove fixedly connected to the upper surface of the jar body, a jar lid movably sleeved on the upper surface of the jar body and located inside the rim groove, and an anti-drop device movably sleeved on the lower surface of the jar body. The inner wall of the jar is threaded with a fastening device. The anti-fall device includes multiple connecting columns. The bottom ends of the multiple connecting columns are fixedly connected to a fixing ring. The lower surface of the fixing ring is provided with multiple reinforcing columns. The upper surface of the fixing ring is provided with multiple screws. The upper surfaces of the multiple reinforcing columns are fixedly connected to the fixing ring through the multiple screws. The upper surfaces of the multiple connecting columns are fixedly connected to a stabilizing ring. The inner sidewall of the stabilizing ring is movably sleeved with the lower part of the outer sidewall of the jar body.

[0005] Furthermore, the outer walls of the stabilizing ring and the fixing ring are jointly provided with a bottom shell.

[0006] Furthermore, the fastening device includes a fixing ring, a waterproof ring is fixedly connected to the inner wall of the fixing ring, a threaded post is fixedly connected to the bottom end of the waterproof ring, a rotating handle is fixedly connected to the lower part of the outer wall of the waterproof ring, the outer wall of the threaded post is threadedly connected to the upper part of the inner wall of the jar body, a connecting pipe is movably connected to the inner wall of the threaded post, and a circular mesh is movably connected to the bottom end of the connecting pipe.

[0007] Furthermore, a rotary valve is fixedly connected to the center of the upper surface of the waterproof ring.

[0008] Furthermore, a telescopic ring is fixedly connected to the outer wall of the circular mesh.

[0009] Furthermore, the outer wall of the jar is threaded with a drain outlet.

[0010] Beneficial effects: This invention effectively solves the problems of poor stability and susceptibility to external damage of traditional clay jars through the modular design of the anti-fall device. The stabilizing ring and the lower outer wall of the jar are connected by a movable sleeve, which can form a flexible buffer when the jar is accidentally tilted or dropped, significantly absorbing external impact and reducing direct collision damage between the jar and the ground. The reinforcing column is connected to the fixing ring by screws to form a detachable rigid connection, which can strengthen the bottom support strength and prevent the jar from tilting due to external shaking. The fixing ring and the bottom shell together form a ring support frame, which can evenly distribute the weight of the jar to the bottom contact surface, optimize the overall center of gravity distribution, and greatly reduce the probability of tipping over due to instability. It improves the structural stability and service life of the clay jar from multiple protection dimensions. This invention achieves a dual improvement in sealing performance and ease of use through a fastening device. The waterproof ring in the fastening device is made of elastic material, which can tightly fill the gap between the jar mouth and the threaded post, forming a highly efficient sealing barrier. This effectively prevents air and external moisture from seeping into the jar, avoiding contamination by miscellaneous bacteria and spoilage of the sour soup during fermentation. The fixing ring is fixed to the outer wall to form a double seal, further enhancing the full coverage sealing effect of the jar opening, which is especially suitable for long-term storage in humid environments. At the same time, the rotating handle adopts a user-friendly mechanical design, allowing users to quickly tighten and loosen the threaded post without the need for additional tools, lowering the barrier to entry. The threaded connection structure, combined with a standardized interface design, is compatible with jar lids of different sizes, improving the adaptability and installation efficiency of the device. In addition, the circular mesh in the fastening device can exert downward pressure on floating objects inside the jar, helping to maintain the uniformity of materials during the fermentation process and ensuring stable fermentation quality.

[0013] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-4 As shown, an improved clay jar for fermenting sour soup is provided, including a jar body 1. A rim groove 2 is fixedly connected to the upper surface of the jar body 1. A jar lid 3 is movably sleeved on the upper surface of the jar body 1 and inside the rim groove 2. An anti-drop device 4 is movably sleeved on the lower surface of the jar body 1. A fastening device 5 is threadedly connected to the inner wall of the jar body 1. The anti-drop device 4 includes connecting posts 6. There are multiple connecting posts 6. The bottom ends of multiple connecting posts 6 are fixedly connected to a fixing ring 7. Multiple reinforcing posts 8 are provided on the lower surface of the fixing ring 7. Multiple screws 9 are provided on the upper surface of the fixing ring 7. The upper surfaces of multiple reinforcing posts 8 are fixedly connected to the fixing ring 7 through multiple screws 9. A stabilizing ring 10 is fixedly connected to the upper surfaces of multiple connecting posts 6. The inner wall of the stabilizing ring 10 is movably sleeved with the lower part of the outer wall of the jar body 1. The core of the earthenware jar includes a jar body 1, which serves as the main space for fermentation of the sour soup, providing a suitable environment for the fermentation process. A rim groove 2 is fixedly connected to the upper surface of the jar body 1, forming a ring-shaped groove around the jar opening. During use, water can be injected into the groove to achieve a primary seal using the water seal principle, effectively preventing outside air from entering the jar body 1. This also facilitates observation of the sealing status; water can be replenished promptly when the water level drops, making operation convenient. A jar lid 3 is movably fitted onto the upper surface of the jar body 1, inside the rim groove 2. The lid 3 works in conjunction with the rim groove 2; after covering the jar opening, its edge can partially... Immersed in the water in the rim groove 2, the water seal effect is further enhanced, preventing air from seeping in through the gaps in the jar mouth. The lower surface of the jar body 1 is movably fitted with an anti-fall device 4, which provides stable support for the jar body 1 and reduces the risk of tipping. The inner wall of the jar body 1 is threaded with a fastening device 5, which is used to achieve a secondary seal at the jar mouth and improve the reliability of the seal. In addition, the outer wall of the jar body 1 is threaded with a drain outlet 19, which is located at the bottom of the jar body 1 and adopts a threaded sealing structure. After fermentation, the sour soup can be directly taken out by opening the drain outlet 19 without frequently opening the jar lid 3, thus reducing the damage to the sealed environment. The anti-fall device 4 serves as the core structure for enhancing the stability of the jar body 1. It employs a multi-layered support design, including multiple connecting columns 6, preferably 3-4, evenly distributed along the circumference to ensure balanced support. A fixing ring 7, made of annular metal or high-strength plastic, is fixedly connected to the bottom of the anti-fall device 4, providing a large support area. Multiple reinforcing columns 8 are installed on the lower surface of the fixing ring 7, perpendicular to it, and their number corresponds to the connecting columns 6. The upper surfaces of the reinforcing columns 8 are fixed to the fixing ring 7 via multiple screws 9, made of corrosion-resistant stainless steel, using threaded connections for reinforcement. The stable connection between the reinforcing column 8 and the fixing ring 7 prevents loosening. The height of the reinforcing column 8 can be adjusted according to the flatness of the ground. When the ground is uneven, the extension length of the reinforcing column 8 can be adjusted by rotating it to keep the fixing ring 7 horizontal, thereby ensuring the stable placement of the jar 1 and preventing the jar 1 from tipping over due to the tilt of the ground. The upper surfaces of multiple connecting columns 6 are fixedly connected to the stabilizing ring 10. The inner side wall of the stabilizing ring 10 is movably fitted to the lower part of the outer side wall of the jar 1. The inner diameter of the stabilizing ring 10 is adapted to the lower outer diameter of the jar 1, which can fit tightly against the outer wall of the jar 1 and form a ring-shaped fixation for the lower part of the jar 1. The center of gravity of the jar 1 is transferred to the fixing ring 7 through the connecting column 6, reducing the overall center of gravity height and improving the anti-tipping ability.

[0015] like Figure 1 and Figure 3 As shown, the outer walls of the stabilizing ring 10 and the fixing ring 7 are jointly provided with a bottom shell 11; The bottom shell 11 is made of wear-resistant materials, such as rubber or modified plastic, and completely covers the outside of the stabilizing ring 10, connecting column 6 and fixing ring 7. On the one hand, it can avoid the metal support structure from directly rubbing against the ground and causing wear. On the other hand, when the jar 1 is accidentally hit or slightly dropped, the bottom shell 11 can absorb the impact force through its own elastic deformation and disperse the impact force to the entire anti-drop device 4, rather than acting directly on the jar 1, effectively preventing the jar 1 from breaking due to impact. At the same time, the bottom shell 11 can also play a role in dust prevention and dirt prevention, preventing debris from entering the interior of the anti-drop device 4 and affecting its structural stability.

[0016] like Figure 1 and Figure 4 As shown, the fastening device 5 includes a fixing ring 12, a waterproof ring 14 fixedly connected to the inner wall of the fixing ring 12, a threaded post 13 fixedly connected to the bottom end of the waterproof ring 14, a rotating handle 15 fixedly connected to the lower part of the outer wall of the waterproof ring 14, the outer wall of the threaded post 13 being threadedly connected to the upper part of the inner wall of the jar body 1, a connecting pipe 16 being movably connected to the inner wall of the threaded post 13, and a circular mesh 18 being movably connected to the bottom end of the connecting pipe 16; a rotary valve 20 is fixedly connected to the center of the upper surface of the waterproof ring 14; and a telescopic circular ring 17 is fixedly connected to the outer wall of the circular mesh 18. The fastening device 5 serves as a reinforced sealing structure for the jar mouth while also ensuring ease of operation. It includes a retaining ring 12, which is annular and fitted around the waterproof ring 14 for fixation and positioning. The waterproof ring 14 is fixedly connected to the inner wall of the retaining ring 12. The waterproof ring 14 is made of food-grade silicone, possessing excellent elasticity, corrosion resistance, and sealing properties. It can withstand the acidic environment of the sour soup without spoilage, ensuring safe and hygienic fermentation. A threaded post 13 is fixedly connected to the bottom end of the waterproof ring 14. The outer wall of the threaded post 13 is threadedly connected to the upper inner wall of the jar body 1, achieving the fastening device 5 and the jar body through threaded engagement. The detachable connection of 1 facilitates installation, disassembly, and cleaning. A rotating handle 15 is fixedly connected to the lower outer wall of the waterproof ring 14. The rotating handle 15 has an anti-slip design, allowing users to easily rotate the threaded column 13 by holding the rotating handle 15 to tighten or loosen the fastening device 5. The operation is labor-saving and convenient. A round mesh 18 is movably connected to the bottom end of the connecting tube 16. The round mesh 18 is made of food-grade stainless steel and has good air permeability and filtration. It can be placed below the surface of the sour soup. On the one hand, it can initially separate the solid materials in the sour soup from the liquid, and on the other hand, it does not affect the activity of microorganisms and the flow of metabolic products during the fermentation process. A telescopic ring 17 is fixedly connected to the outer wall of the round mesh 18. The telescopic ring 17 is made of elastic metal or food-grade elastic plastic and has good telescopic performance. When in use, when the telescopic ring 17 is squeezed in the middle, its overall diameter is reduced. At this time, the squeezed telescopic ring 17 and the round mesh 18 can be placed vertically into the jar body 1. After reaching the designated position, the telescopic ring 17 is released and it will return to its original shape under its own elasticity. After the diameter increases, it fits tightly against the inner wall of the jar body 1.

[0017] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
