Description

Technical Field

[0001] This invention relates to the technical field of vegetable pickling, fermentation, and storage equipment, and in particular to a light-proof storage device for fermented pickled mustard greens. Background Technology

[0002] Fermentation of pickled mustard greens requires a stable, dark, and sealed environment to ensure the fermentation process proceeds normally and develops good flavor and edible quality. Light-proof storage devices used for pickled mustard green fermentation often employ a jar structure combined with a water seal. Relying on light-proof materials and air isolation, they provide suitable conditions for anaerobic fermentation of the mustard greens and are commonly used storage containers in pickling processes.

[0003] In actual use, the pickled mustard greens are first put into the jar, water is added to the rim, and the lid is then placed upside down on the rim so that the edge of the lid is submerged in water to form a water seal. The whole thing is then placed in a dark environment for fermentation. During fermentation, the water level at the rim needs to be checked manually and replenished as needed.

[0004] During the continuous fermentation process, the sealing water inside the jar gradually evaporates over time. As the water level drops, the integrity of the water seal becomes difficult to maintain, affecting the sealing state inside the jar and hindering the stable fermentation of the pickled mustard greens.

[0021] Reference Figure 3 , Figure 4The automatic filling and anti-drying mechanism 4 for sealing water at the tank opening includes a guide pipe 402, which is a rigid hollow tube used to transport sealing water. A clamping plate is fixedly connected to the outside of the tank lid 3. The clamping plate has an L-shaped structure and is used to fix the guide pipe 402. The outer surface of the guide pipe 402 is detachably connected to the inner side of the clamping plate for easy disassembly and assembly. An arc-shaped groove is provided on the outer side of the clamping plate, which is adapted to the outer surface of the guide pipe 402. The inner wall of the slot engages to quickly fix the guide tube 402. A water storage bladder 401 is fixedly connected to the top of the guide tube 402. The water storage bladder 401 is made of elastic material and is used to store reserve sealing water. A water injection hole 403 is provided at the top of the water storage bladder 401 for adding sealing water. A sealing cap 404 is sealed to the inner wall of the water injection hole 403 to prevent leakage. The inner wall of the water reservoir 401 is elastically connected by a compression spring 405. The compression spring 405 provides the contraction force for the water reservoir 401.

The edge of the fixed plate 501 is fixedly connected to the middle section of the arc-shaped handle 2 to ensure that the fixed plate 501 is installed firmly. The movable rod 502 is movably connected through the end face of the fixed plate 501. The movable rod 502 can move up and down along the fixed plate 501. A pull button is fixedly connected to the top of the movable rod 502. The pull button facilitates the pulling of the movable rod 502.

The bottom end of the tension spring 504 is fixedly connected to the top of the pressure plate 503, and the top end of the tension spring 504 is fixedly connected to the bottom of the fixed plate 501 to ensure stable elastic connection. The bottom of the pressure plate 503 abuts against the top surface of the lid 3 to achieve the pressing and sealing of the lid 3.

[0023] Working principle: When using this pickled mustard greens fermentation and light-proof storage equipment, the equipment is first moved by the arc-shaped handle 2 connected to the outer side of the jar body 1. When it is necessary to fix the arc-shaped handle 2, rotate the nut connected to the thread on the outer surface of the positioning pin to lock the side of the nut to the outer side of the arc-shaped handle 2. With the help of the limiting ring fixedly connected to the surface of the positioning pin, the arc-shaped handle 2 is firmly locked to the end face of the limiting ring, achieving the effect of fixing the arc-shaped handle 2 in a vertical state and preventing the arc-shaped handle 2 from shaking during subsequent operations. When operating the sealing mechanism 5, first pull the button with anti-slip texture at the top of the movable rod 502 to move the pressure plate 503 upward and compress the tension spring 504 fixedly connected to the bottom surface of the fixed plate 501. Then, put the jar lid 3 upside down on the jar edge 6 of the jar body 1, release the button, and the tension spring 504 returns to its original position, pushing the bottom of the pressure plate 503 to tightly abut against the top surface of the jar lid 3. At the same time, the edge of the jar lid 3 is immersed in the water of the jar edge 6 to form an initial water seal, completing the sealing operation of the jar lid 3. Next, the automatic water replenishment and anti-drying mechanism 4 at the tank opening is activated. First, the sealing cap 404 at the water injection hole 403 on the top of the water storage bladder 401 is opened, and an appropriate amount of clean water is injected into the water storage bladder 401. Then, the sealing cap 404 is tightened. The water storage bladder 401 is fixed to the guide pipe 402 through the arc-shaped groove of its outer plate. The bottom end of the guide pipe 402 extends to the liquid surface at the rim 6. At this time, the lower surface of the float ball 409, which is rotatably connected to the bottom of the connecting plate 408 through a pin, floats on the liquid surface at the rim 6, and the upper surface is in sealed contact with the bottom end of the guide pipe 402. The inner wall of the water storage bladder 401 is kept in its initial state by the compression spring 405 fixedly connected at both ends. When the water in the rim 6 decreases due to evaporation during the fermentation of the pickled mustard greens, the liquid level drops, causing the float ball 409 to move down synchronously. The float ball 409 and the bottom end of the guide pipe 402 are then sealed together. Once the seal is released, the water in the water storage bladder 401, under its own weight and the elastic force of the compression spring 405, replenishes water into the rim 6 through the guide pipe 402. At the same time, the float 409 moves upward as the liquid level rises, and the slider 407 slides synchronously in the groove 406 of the guide pipe 402 until the upper surface of the float 409 makes sealing contact with the bottom end of the guide pipe 402 again, at which point water replenishment stops. If the liquid level drops again, the above water replenishment process is repeated to always keep the water level in the rim 6 stable and prevent the water seal from drying out. Throughout the entire use process, the water storage bladder 401 is stably fixed to the outside of the rim 3 by the arc-shaped groove of the clamping plate, and the sealing cap 404 ensures the sealing of the water storage bladder 401. Finally, through the above operation steps and linkage process, the rim 3 is tightly sealed and automatically replenished to prevent drying out.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
