Description

Technical Field

[0001] This utility model relates to the field of pickling box technology, specifically to a pickling box. Background Technology

[0002] Existing food storage or pickling containers typically consist of a body and a sealing lid, which together form a sealed cavity. This allows for vacuuming to reduce the air content within the cavity, thereby extending the shelf life of food or achieving a pickling effect. Generally, these containers have a sealing ring on the lid, which connects to an external vacuum system via a piston or valve to extract air from the cavity, creating a vacuum environment. However, in existing designs, the sealing lid usually only has a single operating mode, limiting users to a single storage or pickling operation. This lack of flexibility restricts its application scenarios.

[0003] In addition, during the vacuuming process, some containers are prone to air leakage due to the complex structure of the sealing cap or the loose fit between the opening and the piston, which makes the vacuum unstable and affects the storage and pickling effect. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention provides a pickling box. By setting a rotatable piston on the sealing lid, the container can be freely switched between storage mode and pickling mode, realizing multiple uses of one box. It can be used as an ordinary sealed storage box, or it can be switched to pickling mode through the vacuum component, which greatly improves the flexibility and applicability of use.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A pickling box, comprising:

[0007] The box body has a receiving cavity;

[0008] A sealing cap, which is used to cover the box body, is provided with a first sealing ring and has a through hole;

[0009] A piston is rotatably engaged in the through hole. When the piston rotates to a first angle position, the box is in storage mode, and when the piston rotates to a second angle position, the box is in pickling mode.

[0010] It also includes a vacuum assembly that is detachably mounted on the sealing cover. When the box is in the marinating mode, the vacuum assembly is connected to the sealing cover and extracts the air from the containment cavity, so that the piston is pressed down and blocks the through hole, thereby creating a vacuum state in the containment cavity.

[0011] Furthermore, the sealing cover has a first groove formed along the lower part of the cover, and the through hole is opened at the center of the first groove;

[0012] The piston has a plurality of first protrusions arranged circumferentially at its bottom end. When the piston is engaged in the through hole, the plurality of first protrusions abut against the bottom of the sealing cap, and there is a gap between the piston and the through hole for air extraction.

[0013] Furthermore, the piston is also provided with a raised edge, and a plurality of second protrusions are provided at circumferential intervals along the outer edge of the raised edge;

[0014] The first groove is provided with a plurality of slots arranged at intervals along the circumference, and the plurality of slots correspond to a plurality of second protrusions;

[0015] When the piston rotates to the second angle position, the plurality of second protrusions engage with the plurality of slots.

[0016] Furthermore, the first groove is also provided with a plurality of limiting blocks arranged circumferentially and close to the slot, and the plurality of limiting blocks are used to abut against the plurality of second protrusions to achieve rotational limiting.

[0017] Furthermore, the top of the sealing cap is provided with a second groove, and the vacuum assembly is detachably snapped into the second groove.

[0018] Furthermore, the vacuum assembly includes an air pump and a bottom connecting plate that engages with the second groove. The bottom connecting plate has an air intake port, and the air inlet of the air pump is connected to the air intake port through an air pipe.

[0019] When the air pump is working, it can extract the air from the receiving cavity through the gap, so as to create a negative pressure in the receiving cavity and cause the convex edge to press down and block the gap, thereby creating a vacuum in the receiving cavity.

[0020] Furthermore, the bottom of the bottom connecting plate is provided with a plug-in block, which can be inserted into the first groove. The plug-in block is covered with a first sealing ring to achieve sealing in the plugged state.

[0021] Furthermore, the outer edge of the first groove is provided with a stepped groove, and the first sealing ring is provided with a stepped protrusion that cooperates with the stepped groove.

[0022] Furthermore, the vacuum assembly also includes a battery, a control board, and a charging module. The battery is electrically connected to the vacuum pump to supply power to it, the control board is electrically connected to the vacuum pump to control its start and stop, and the charging module is used to charge the battery.

[0023] Furthermore, the sealing cover is provided with a third groove, and the first sealing ring is engaged in the third groove;

[0024] When the sealing cap is placed on the box body, the edge of the box body is inserted into the third groove and squeezes the first sealing ring to achieve a seal.

[0025] In summary, this utility model has the following technical effects:

[0026] 1. This utility model of a pickling box, by setting a rotatable piston on the sealing lid, allows the container to switch freely between storage mode and pickling mode, realizing multiple uses in one box. It can be used as an ordinary sealed storage box, or it can be switched to pickling mode through the vacuum component, which greatly improves the flexibility and applicability of use.

[0027] 2. This utility model of a marinating box allows air to be extracted from the containment cavity through the gap between the through-hole and the piston when the vacuum assembly is activated. Under negative pressure, the piston automatically presses down and seals the through-hole, enabling the containment cavity to quickly enter and maintain a stable vacuum state. This simplifies the fit between the sealing cap and the vacuum assembly and effectively avoids the air leakage problem caused by the loose seal between the cap opening and the piston in existing technologies, thus improving the stability of vacuum maintenance. Therefore, it better ensures the preservation time and marinating effect of the food, while also facilitating repeated operation by the user, significantly enhancing its practicality.

[0036] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] like Figure 1-6 The pickling box shown includes a box body 1, a sealing lid 2, a piston 3, and a vacuum assembly 4. The box body 1 has a receiving cavity 11 for holding food to be stored or pickled; the sealing lid 2 covers the open end of the box body 1, and the sealing lid 2 has a first sealing ring 21 for sealing with the box body 1; the sealing lid 2 also has a through hole 22.

[0040] The piston 3 is rotatably engaged in the through hole 22. When the piston 3 is in the first angular position, the receiving cavity 11 is in the storage mode; when the piston 3 is in the second angular position, the receiving cavity 11 is in the pickling mode.

[0041] When the container 11 is in the pickling mode, the vacuum assembly 4 is connected to the sealing cap 2, and the air in the container 11 is extracted by the vacuum assembly 4. The piston 3 is pressed down under the action of pressure difference and blocks the through hole 22, thereby forming a vacuum seal in the container 11. By setting a rotatable piston 3 on the sealing cap 2, the storage and pickling modes can be flexibly switched. Users can freely select the function according to their needs, which significantly improves the efficiency of the container.

[0042] See Figure 5 The sealing cap 2 has a raised section forming a first groove 23, and a through hole 22 is located at the center of the first groove 23. The bottom end of the piston 3 is provided with multiple first protrusions 31 distributed circumferentially. When the piston 3 is engaged in the through hole 22, the first protrusions 31 abut against the bottom of the sealing cap 2, thereby preventing the piston 3 from falling out of the through hole 22, and a gap is formed between the piston 3 and the through hole 22. This gap forms an air passage during the evacuation process, ensuring evacuation efficiency. After the evacuation is completed, the piston 3 automatically presses down and seals the gap, forming a reliable vacuum seal.

[0043] Furthermore, the piston 3 is provided with a raised edge 32, and multiple second protrusions 33 are arranged circumferentially along the outer edge of the raised edge 32. The first groove 23 of the sealing cover 2 is provided with a corresponding slot 24 along the circumferential direction. When the piston 3 rotates to the second angle position, the second protrusions 33 and the slots 24 engage with each other to lock the mode switching, providing a clear positioning feel, avoiding user misoperation, and enhancing the fixed stability of the piston 3, making the pickling process more reliable.

[0044] It should be noted that when the piston 3 rotates to the first angle position, the second protrusion 33 disengages from the slot 24, and when the piston 3 rotates to the second angle position, the second protrusion 33 engages with the slot 24. The specific rotation direction can be set to clockwise or counterclockwise according to the actual structural requirements to ensure the flexibility and applicability of the assembly.

[0045] Specifically, multiple limiting blocks 25 are arranged circumferentially in the first groove 23. The limiting blocks 25 are close to the slot 24 and abut against the second protrusion 33 to achieve rotational limiting. The limiting blocks 25 ensure that the piston 3 can only switch between the storage mode and the pickling mode, avoiding invalid rotation and improving the convenience of operation and sealing reliability.

[0046] See Figure 3The top of the sealing cover 2 is provided with a second groove 26, and the vacuum assembly 4 is detachably snapped into the second groove 26. The vacuum assembly 4 includes a vacuum pump 41 and a bottom connecting plate 42 that snaps into the second groove 26. The bottom connecting plate 42 has an air intake port 421, and the air inlet of the vacuum pump 41 is connected to the air intake port 421 through an air pipe. The vacuum assembly 4 adopts a detachable design, which is convenient for cleaning and maintenance, and allows for the selection of whether to install the vacuum pump 41 as needed, improving the flexibility and applicability of the product. When the vacuum pump 41 is working, it can extract the air in the receiving cavity 11 through the gap, so that a negative pressure is formed in the receiving cavity 11, and the protrusion 32 is pressed down to block the gap, thereby creating a vacuum in the receiving cavity 11.

[0047] Specifically, each of the multiple second protrusions 33 is equipped with a first indicator 34, and the second groove 26 of the sealing cover 2 is equipped with a corresponding second indicator 261. Simultaneously, the top of the piston 3 is equipped with a rotating block 35 for easy gripping and operation by the user, and the rotating block 35 has a clearly visible rotation mark 36. During use, the user only needs to rotate the rotating block 35 to the second angle position, aligning the first indicator 34 with the second indicator 261, to intuitively determine that the receiving cavity 11 has entered the marinating mode. Afterwards, the vacuum assembly 4 can smoothly engage in the second groove 26 and extract the air from the receiving cavity 11, thereby creating a stable vacuum environment within the cavity. The user can quickly and accurately switch modes, avoiding air leakage or insufficient vacuum caused by improper operation, thus significantly improving the reliability and convenience of the storage and marinating process.

[0048] See Figure 6 The bottom of the bottom connecting plate 42 is provided with a plug-in block 422, which is inserted into the first groove 23. The plug-in block 422 is covered with a second sealing ring 423. The outer edge of the first groove 23 is provided with a stepped groove 231, and the second sealing ring 423 is provided with a stepped protrusion 4231 that cooperates with the stepped groove 231. Through the stepped sealing structure, the sealing performance between the vacuum assembly 4 and the sealing cover 2 is effectively improved, preventing air leakage and ensuring the stability and durability of vacuum maintenance.

[0049] It should be noted that when the plug block 422 is inserted into the first groove 23, the second sealing ring 423 is squeezed by the plug block 422 and the first groove 23 together, thus forming a reliable sealing structure. In this state, the vacuum assembly 4 can effectively extract the air from the first groove 23 through its suction port 421. Furthermore, when the piston 3 rotates to the second angle position, a gap is reserved between the piston 3 and the through hole 22. This gap connects the first groove 23 with the receiving cavity 11, allowing the vacuum assembly 4 to continue to extract the air from the receiving cavity 11 through this gap, and creating a negative pressure in the receiving cavity 11 to press down the protrusion of the piston 3 and block the through hole 22. That is, the gap between the piston 3 and the through hole 22 is blocked, thereby forming a stable vacuum environment in the receiving cavity 11, ensuring the continuity of the air extraction path and the reliability of the seal, and significantly improving the holding effect of the vacuum cavity, thereby effectively extending the preservation time of the food and accelerating the marinating speed, enhancing the practicality of the overall device and the user experience.

[0050] Furthermore, the vacuum assembly 4 also includes a battery 43, a control board 44, and a charging module 45. The battery 43 is used to power the vacuum pump 41, the control board 44 is used to control the start and stop of the vacuum pump 41, and the charging module 45 is used to charge the battery 43.

[0051] Specifically, the vacuum assembly 4 also includes a housing 46 that is interlocked with the bottom connecting plate 42. The housing 46 has an installation cavity, in which the vacuum pump 41, battery 43, control board 44, and charging module 45 are all installed. The air outlet of the vacuum pump 41 can be connected to the outside through an air pipe. Alternatively, the air can be discharged into the installation cavity and discharged to the outside through the gap created between the bottom connecting plate 42 and the housing 46, thereby achieving vacuuming of the receiving cavity 11. The vacuum assembly 4 can work independently without an external power source, enhancing the portability of the marinating box. At the same time, the battery 43 can be recharged and used repeatedly, reducing long-term usage costs.

[0052] See Figure 4 The bottom of the sealing cap 2 has a third groove 27, and the first sealing ring 21 is engaged in the third groove 27. When the sealing cap 2 is closed on the box body 1, the edge of the box body 1 is inserted into the third groove 27 and presses against the first sealing ring 21, thereby forming a reliable sealing connection between the sealing cap 2 and the box body 1, improving the stability of the sealing structure, and effectively avoiding air leakage caused by poor sealing, thus ensuring the durability of the vacuum environment during pickling or storage.

[0053] In this embodiment, the vacuum assembly 4 also includes a sling 47 disposed on its exterior, allowing the user to easily extract or carry the vacuum assembly 4. This structure not only improves the portability and ease of use of the assembly, but also avoids directly grasping the assembly body by hand during frequent installation or disassembly, thereby reducing the risk of slippage or damage, and further improving the overall durability of the device and the user experience.

[0054] In summary, this utility model of a pickling box, by setting a rotatable piston 3 on the sealing lid 2, allows the container to freely switch between storage mode and pickling mode, realizing multiple uses in one box. It can be used as an ordinary sealed storage box, or it can be switched to pickling mode through the vacuum component 4, which greatly improves the flexibility and applicability of use.

[0055] This invention relates to a pickling box. When the vacuum assembly 4 is activated, air in the containing cavity 11 can be extracted through the gap between the through hole 22 and the piston 3. Under negative pressure, the piston 3 automatically presses down and seals the through hole 22, thereby allowing the containing cavity 11 to quickly enter and maintain a stable vacuum state. This simplifies the fit between the sealing cover 2 and the vacuum assembly 4, and effectively avoids the air leakage problem caused by the loose seal between the cover opening and the piston 3 in the prior art, improving the stability of vacuum maintenance. Therefore, it can better guarantee the preservation time and pickling effect of food, and also facilitates repeated operation by users, significantly enhancing its practicality.
