Description

Technical Field

[0001] The invention relates to the technical field of fresh-keeping boxes, in particular to an antiseptic fresh-keeping box. Background Art

[0002] At present, the common fresh-keeping boxes on the market mainly rely on simple sealing structures, such as achieving a certain degree of sealing performance through a sealing ring between the box cover and the box body. This type of traditional fresh-keeping box usually adopts a press-type or screw-on sealing design, using the box cover to press the sealing ring to isolate the air, thereby delaying the oxidation and corruption of fresh food. These fresh-keeping boxes are relatively simple in structure, easy to operate, and suitable for storing daily food. However, as users' requirements for food preservation effects increase, the performance limitations of traditional fresh-keeping boxes are gradually revealed, especially when storing perishable foods such as fresh meat, fruits and vegetables, the preservation effect is not ideal.

[0003] The main defects of the prior art include the following: Unable to achieve efficient vacuum freshness lock: Traditional fresh-keeping boxes lack vacuum suction function, and the residual oxygen in the box will accelerate the oxidation and corruption of food, which cannot meet the needs of long-term storage of fresh food. At the same time, although the fresh-keeping device using an electric vacuum pump can reduce the oxygen content to a certain extent, it needs to rely on electricity support, which increases the cost of use and the complexity of the equipment, and is not convenient for outdoor use or home energy saving needs.

[0004] Inadequate sealing performance: Since traditional fresh-keeping boxes rely only on simple sealing rings, their sealing performance is easily affected by external forces. For example, when the box body is deformed or the sealing ring is aged, it will lead to loose sealing and air leakage, thereby reducing the preservation effect. In addition, during use, users cannot adjust the sealing state of the box according to specific needs, such as switching to pressurized unlocking mode.

[0005] Lack of multifunctional filtering protection: Traditional fresh-keeping boxes usually do not have gas filtering functions, and it is difficult to effectively control the moisture and oxygen in the box. Moreover, dust and microorganisms from the outside can easily enter the box through weak seals and contaminate food. Existing desiccants or deoxidizers usually require users to place them separately, lack an organic combination with the structure of the fresh-keeping box, are cumbersome to use, and have limited effects.

[0006] In summary, the existing technology has great limitations in terms of preservation effect, sealing performance and ease of operation, and cannot meet the needs of users for efficient, environmentally friendly and reliable food preservation. Therefore, how to design a multifunctional preservation device that can be manually operated and achieve vacuum freshness locking, gas filtration and fast mode switching at the same time has become a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0026] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0027] An antiseptic fresh-keeping box provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] Combination Figure 1-Figure 7 As shown, the present invention provides an antiseptic fresh-keeping box, which includes a fresh-keeping box body 100, a box cover body 200, and a drive disk assembly 300 and an air extraction assembly 400 arranged on the surface of the box cover body 200.

[0029] The outer periphery of the fresh-keeping box body 100 and the box cover body 200 is provided with a plurality of buckle ears 110 and lock strips 210 arranged one by one, which are used for buckling connection between the fresh-keeping box body 100 and the box cover body 200. A sealing ring 220 abutting against the top surface of the fresh-keeping box body 100 is embedded and installed on the bottom surface of the box cover body 200 to achieve an airtight connection between the box body and the box cover.

[0030] 1. Structure and function of the drive disk assembly 300 Specifically, the drive disk assembly 300 includes a turntable seat 310 and a rocker 320 rotatably mounted on the surface of the turntable seat 310. A rotating pin 321 is rotatably mounted on the surface of the rocker 320. When the user rotates the rocker 320, the air extraction assembly 400 can be driven to work through the turntable seat 310 to achieve the function of exhausting or pressurizing the box.

[0031] The surface of the turntable seat 310 is provided with a sleeve groove 311 for mounting the adjusting slide 421 of the air extraction assembly 400. In addition, the turntable seat 310 is also provided with a storage groove matching the shape of the rocker 320 and the rotating pin 321 for folding and storing the rocker 320, thereby improving portability and storage convenience.

[0032] 2. Structure and working principle of the air extraction assembly 400 The vacuum assembly 400 includes a main rotating seat 410, a fixed guide plate 420, and an inner air duct 430 and an outer air duct 440 located on both sides of the fixed guide plate 420. The bottom surface of the fixed guide plate 420 is provided with a sliding protrusion that penetrates the main rotating seat 410 and is slidably connected to the box cover body 200, which is used to keep the fixed guide plate 420 and the box cover body 200 synchronously stationary.

[0033] The main rotating seat 410 is rotatably mounted on the inner side of the box cover body 200, and a plurality of piston slide grooves 411 are provided on the inner side thereof. A piston block 450 is slidably mounted in the piston slide groove 411, and a piston ring is provided on the surface of the piston block 450, and the outer periphery of the piston block 450 is slidably abutted against the inner side of the piston slide groove 411 to ensure air tightness.

[0034] One end of the piston block 450 is movably connected to a connecting rod 460, and the other end of the connecting rod 460 is slidably sleeved on the inner side of the annular sliding groove 422 of the fixed guide plate 420 through a sliding pin 461. By adjusting the eccentricity by adjusting the sliding protrusion 421 between the fixed guide plate 420 and the rotating plate seat 310, a quick switch between the exhaust mode and the pressurization mode can be achieved.

[0035] 3. Filtering function of inner airway 430 and outer airway 440 The inner air channel 430 and the outer air channel 440 are arranged symmetrically on the outer periphery of the main rotating seat 410, wherein: The bottom surface of the inner air passage 430 is connected to the interior of the fresh-keeping box body 100 through the air port on the bottom surface of the box cover body 200; The top surface of the external air duct 440 is connected to the external environment through the air port on the top surface of the box cover body 200 .

[0036] A filter box is detachably installed on the inner side of the inner air passage 430 and the outer air passage 440. The upper and lower ends of the filter box are in a grid shape, and the interior is filled with desiccant particles and deoxidizer particles. The design of the filter box can not only effectively absorb moisture and filter oxygen, but also block external dust and microbial contamination, further improving the preservation effect.

[0037] 4. Internal structure of the fresh-keeping box body 100 The inner side of the fresh-keeping box body 100 is detachably mounted with an inner liner box 120, which is made of food-grade stainless steel or polyethylene, has good anti-corrosion and easy-to-clean properties, and can be disassembled and used according to user needs. The outer surface of the fresh-keeping box body 100 is fixedly mounted with an insulation sleeve 130, which is used to isolate the influence of external heat on the interior of the fresh-keeping box, and further improve the preservation performance of fresh food.

[0038] 5. Eccentric adjustment and mode switching The axis of the fixed guide plate 420 deviates from the center of the main rotating seat 410. By adjusting the sliding position of the sliding protrusion 421 in the sliding sleeve groove 311 of the rotating seat 310, the eccentricity and eccentricity direction of the fixed guide plate 420 can be flexibly adjusted. When the fixed guide plate 420 is set eccentrically, the air extraction component 400 can be in a suction state, and the air in the box is discharged through the movement of the piston block 450; when the fixed guide plate 420 is restored to a concentric setting, the air extraction component 400 can be in a pressurized state, and the box is pressurized through the reverse piston movement to achieve unlocking of the fresh-keeping box.

[0039] 6. Operation process and effect The user rotates the rocker 320 to drive the turntable 310 to drive the exhaust assembly 400 to work. In the vacuum fresh-keeping mode, the air in the box is exhausted to achieve the fresh-keeping effect of the low-oxygen environment in the box; in the pressurized unlocking mode, the box body and the box cover are quickly separated through reverse operation. At the same time, dust and water vapor are filtered through the filter boxes in the inner air channel 430 and the outer air channel 440, further optimizing the storage environment in the box.

[0040] Through the above design, the antiseptic fresh-keeping box of the present invention can efficiently realize the vacuum fresh-keeping and pressurized unlocking functions. Combined with the filtering component and the sealing structure, it can significantly improve the storage time and preservation effect of fresh food. It is simple to operate, easy to clean, and suitable for a variety of usage scenarios.

[0041] The working principle and use process of the present invention: The antiseptic fresh food preservation box of the present invention realizes the vacuum freshness locking and pressurized unlocking functions of the box environment through the cooperation of the driving disk group 300 and the exhaust assembly 400. The main working principle is as follows: Vacuum suction function: the user shakes the rocker 320 in the drive disk assembly 300 to rotate the drive turntable seat 310, driving the main turntable 410 in the suction assembly 400 to rotate relative to the fixed guide disk 420. The fixed guide disk 420 remains relatively still with the box cover body 200 through the bottom sliding protrusion, and the main turntable 410 rotates freely.

[0042] The fixed guide plate 420 cooperates with the piston block 450 and the connecting rod 460 in the main rotating seat 410 through eccentric adjustment to generate reciprocating motion.

[0043] When the piston block 450 slides in the piston slide groove 411, the air in the fresh-keeping box body 100 is extracted through the inner air passage 430 and the outer air passage 440, thereby achieving a vacuum state in the box.

[0044] Pressurization unlocking function: When the user switches the eccentric direction of the fixed guide plate 420 and the turntable seat 310, the suction assembly 400 enters the pressurization mode.

[0045] In this mode, the movement direction of the piston block 450 is reversed, and air is pressed into the fresh-keeping box body 100 through the vacuum assembly 400. The airflow directions inside the inner air duct 430 and the outer air duct 440 are switched, so that the external environment airflow is input into the fresh-keeping box body 100 after being filtered, and the airtight locking state between the box cover body 200 and the fresh-keeping box body 100 is released, making it easier to open the box cover.

[0046] Filter protection function: The inner air passage 430 and the outer air passage 440 are embedded with detachable and replaceable filter boxes, which are filled with desiccant particles and deoxidizer particles. During the process of vacuuming or pressurizing, the outside air is purified when passing through the filter box, effectively filtering out moisture, dust and oxygen, thereby ensuring the cleanliness and low oxygen state of the box environment and improving the antiseptic and fresh-keeping effect of food.
