In recent years, people's health awareness has gradually increased, and their requirements for food storage have become increasingly stringent. Refrigerators, which only store food through refrigeration and freezing, can no longer meet people's needs.

[0003] To address food preservation issues, various manufacturers have introduced different preservation technologies. For example, vacuum preservation involves placing food in a vacuum container. In a vacuum environment, microorganisms and enzymes are difficult to survive, requiring a long time for microbial growth to occur. Furthermore, the vacuum significantly reduces the amount of oxygen in the container, preventing chemical reactions from completing and preventing oxidation, thus preserving food's freshness for extended periods.

The fresh-keeping box has a storage cavity formed therein, the fresh-keeping box being detachably connected to the door, and the vacuum assembly being used to vacuum the storage cavity. The vacuum assembly includes a vacuum connector assembly, which is flippably mounted on the door and detachably connected to the storage cavity. When the vacuum connector assembly is connected to the storage cavity, the vacuum assembly can vacuum the storage cavity. When the vacuum connector assembly is flipped and separated from the fresh-keeping box, the fresh-keeping box can be removed from the door. This technology achieves the purpose of vacuuming the fresh-keeping box through the vacuum assembly, thereby extending the freshness period of food placed in the fresh-keeping box.

[0005] However, the applicant found that the existing fresh-keeping boxes and vacuum extraction devices have at least the following defects: (1) When the user performs the vacuum extraction operation, the steps are cumbersome and complicated, and the specific steps are as follows: put the fresh-keeping box into the base and fix it - connect the vacuum extraction device to the fresh-keeping box - vacuum - separate the vacuum extraction device from the fresh-keeping box - take out the fresh-keeping box; (2) The existing vacuum extraction device can only vacuum one fresh-keeping box at a time, and the efficiency is low; (3) The existing fresh-keeping boxes generally have only one volume size, and the position of the fresh-keeping box in the refrigerator is fixed, so the user cannot choose a fresh-keeping box of the appropriate size according to their needs.

DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0047] The following is attached with the instruction manual Figures 1 to 12 The fresh-keeping box device and refrigeration equipment of the present invention are described in detail in Examples 1 and 2.

[0048] Example 1

[0049] This embodiment describes the fresh-keeping box device of the present invention in detail.

[0050] The fresh-keeping box device of this embodiment includes a fresh-keeping box 10 and an exhaust device 20. Figures 1 to 4 Preferably, the fresh-keeping box 10 is provided with a first card slot 1011 and an air extraction interface portion 1012, and the air extraction device 20 is provided with a buckle assembly and an air extraction assembly. The buckle assembly is arranged on the air extraction device 20 in a liftable manner, and when the fresh-keeping box 10 is pushed to be placed in the air extraction device 20, the buckle assembly is forced and rises. When the fresh-keeping box 10 abuts against the air extraction device 20, the force applied to the buckle assembly is stopped, the buckle assembly descends and engages with the first card slot 1011, and at the same time, the air extraction assembly is connected to the air extraction interface portion 1012, as shown. Figures 2-4 More preferably, there are multiple fresh-keeping boxes 10, and the volumes of the multiple fresh-keeping boxes 10 can be the same or different.

[0051] When the fresh-keeping box device of this embodiment is pushed to be placed in the air extraction device 20, the buckle assembly is subjected to force and rises. When the fresh-keeping box 10 abuts against the air extraction device 20, the force on the buckle assembly is stopped, and the buckle assembly descends and engages with the first slot 1011. At the same time, the air extraction assembly is connected to the air extraction interface part 1012. It can be seen that when the user performs the vacuum operation, the fresh-keeping box 10 is pushed into the air extraction device 20, so that the fresh-keeping box 10 is fixedly connected to the air extraction device 20, and the air extraction assembly of the air extraction device 20 is connected to the air extraction interface part 1012 of the fresh-keeping box 10; conversely, the fresh-keeping box 10 is pulled out of the air extraction device 20, so that the fresh-keeping box 10 is separated from the air extraction device 20, and the air extraction assembly of the air extraction device 20 is separated from the air extraction interface part 1012 of the fresh-keeping box 10. That is, the fresh-keeping box device of this embodiment, when the user performs the vacuum operation, only needs to perform two steps: pushing the fresh-keeping box 10 and pulling the fresh-keeping box 10. The operation steps are simple, and compared with the existing technology, the operation process is simplified. That is, the fresh-keeping box device of this embodiment solves the technical problem of cumbersome and complicated steps when the user performs the vacuum operation in the existing technology.

[0052] According to a preferred embodiment, the air extraction device 20 is further provided with a slide plate assembly, which is slidably provided on the air extraction device 20, and the buckle assembly is provided at the movable end of the slide plate assembly. When the fresh-keeping box 10 is pushed to be placed in the air extraction device 20, force is applied to the slide plate assembly and the slide plate assembly slides in a direction close to the buckle assembly. The buckle assembly is lifted up by the contact between the slide plate assembly and the buckle assembly. When the fresh-keeping box 10 abuts against the air extraction device 20, the force applied to the slide plate assembly is stopped, the slide plate assembly slides in a direction away from the buckle assembly, the slide plate assembly is separated from the buckle assembly, and the buckle assembly is lowered. Figure 2 or Figure 3 As shown. The movable end of the slide assembly is the sliding end, specifically the end away from the button portion 2041 of the slide assembly. In the fresh-keeping box device of the preferred technical solution of this embodiment, a slide assembly is also provided on the exhaust device 20. By sliding the slide assembly in different directions, it is possible to apply force to the buckle assembly or cancel the force on the buckle assembly, so that the buckle assembly is lifted by the squeezing force, or lowered under the action of its own gravity after the squeezing force is canceled. The fresh-keeping box device of the preferred technical solution of this embodiment controls the lifting and lowering of the buckle assembly through the slide assembly, which has the advantages of easy operation and high reliability.

[0053] The fresh-keeping box device of the preferred technical solution of this embodiment is not limited to applying force to the buckle assembly through the slide assembly. When the fresh-keeping box 10 is pushed to be placed in the exhaust device 20, the buckle assembly can be lifted upward by squeezing the buckle assembly by the fresh-keeping box 10. When the fresh-keeping box 10 abuts against the exhaust device 20, the pushing of the fresh-keeping box 10 is stopped, the squeezing force on the buckle assembly disappears, and the buckle assembly descends under the action of its own gravity.

[0054] According to a preferred embodiment, one of the fresh-keeping box 10 and the exhaust device 20 is further provided with a protrusion 1013, and the other is further provided with a first guide groove 2021.

When the fresh-keeping box 10 is pushed and placed in the exhaust device 20, the protrusion 1013 is engaged in the first guide groove 2021. Preferably, the fresh-keeping box 10 is provided with a protrusion 1013, and the exhaust device 20 is provided with a first guide groove 2021. Figure 5 and Figure 11The fresh-keeping box device of the preferred technical solution of this embodiment has a protrusion 1013 provided on one of the fresh-keeping box 10 and the exhaust device 20, and a first guide groove 2021 provided on the other. During the process of pushing or pulling the fresh-keeping box 10, the protrusion 1013 engages with the first guide groove 2021, allowing the fresh-keeping box 10 to slide along a predetermined path, ensuring that the sliding path of the fresh-keeping box 10 does not deviate. This ensures that when the fresh-keeping box 10 abuts the exhaust device 20, the buckle assembly can engage with the first engaging groove 1011, and the exhaust assembly can be connected to the exhaust interface portion 1012.

[0055] According to a preferred embodiment, the fresh-keeping box device further includes a base 30, such as Figure 1 or Figure 2 Preferably, the bottom support 30 is located below the air extraction device 20, as shown.

In the fresh-keeping box device of the preferred technical solution of this embodiment, when the slide assembly contacts the buckle 2031, the slide assembly applies an extrusion force to the buckle 2031, thereby lifting the buckle 2031; when the slide assembly separates from the buckle 2031, the extrusion force applied by the slide assembly to the buckle 2031 disappears, and the buckle 2031 can descend under the action of its own gravity and engage with the first slot 1011.

[0063] According to a preferred embodiment, the buckle assembly further includes a first elastic member 2032, such as Figure 9 or Figure 10As shown. Preferably, the first elastic member 2032 is connected to the buckle 2031, and when the slide assembly contacts the buckle 2031 and causes the buckle 2031 to rise upward, the first elastic member 2032 is in an elastically compressed state. When the slide assembly slides away from the buckle 2031 and separates from the buckle 2031, the first elastic member 2032 is in an elastically extended state and pushes the buckle 2031 downward. More preferably, the first elastic member 2032 is a spring. In the preferred technical solution of this embodiment, the fresh-keeping box device further comprises the buckle assembly, which is in an elastically compressed state when the buckle 2031 rises upward. When the slide assembly separates from the buckle 2031, the first elastic member 2032 returns to its original position, thereby enabling the buckle 2031 to be pushed downward by the first elastic member 2032, ensuring that the buckle 2031 is engaged in the first slot 1011. Furthermore, through the action of the first elastic member 2032, the buckle 2031 can be firmly inserted into the first slot 1011, and external force is required to separate the buckle 2031 from the first slot 1011, thereby preventing the buckle 2031 from shaking and affecting the accuracy of the docking between the vacuum assembly and the vacuum interface part 1012.

[0064] According to a preferred embodiment, the buckle assembly further includes a buckle stopper 2033, such as Figure 9 or Figure 10 Preferably, the buckle stopper 2033 and the first elastic member 2032 are located on either side of the buckle 2031, and when the buckle 2031 is in the raised state, the buckle stopper 2033 and the first elastic member 2032 are used to prevent the horizontal movement of the buckle 2031. In the preferred technical solution of this embodiment, the fresh-keeping box device further comprises a buckle stopper 2033. When the buckle 2031 is in the raised state, the buckle stopper 2033 and the first elastic member 2032 on both sides can limit the forward and backward movement of the buckle 2031, ensuring that the button portion 2041 stops being pressed and the buckle 2031 can be precisely engaged with the first slot 1011.

[0065] According to a preferred embodiment, the slide assembly includes a button portion 2041, a slide 2042 and a second elastic member 2043.

By pressing the button portion 2041 and applying force to the slide plate 2042, the slide plate 2042 slides toward the buckle 2031. The contact between the slide plate 2042 and the buckle 2031 causes the buckle 2031 to rise upward, while the second elastic member 2043 is in an elastically compressed state. When the button portion 2041 is stopped, the slide plate 2042 slides away from the buckle 2031 under the elastic force of the second elastic member 2043, and the slide plate 2042 and the buckle 2031 are separated. Preferably, the second elastic member 2043 is a spring. In the preferred technical solution of the fresh-keeping box device of this embodiment, preferably, third slots 2044 are further provided at both ends of the second elastic member 2043. When the button portion 2041 is pressed, the third slots 2044 limit the position of the second elastic member 2043, thereby placing the second elastic member 2043 in an elastically compressed state. The preferred technical solution of this embodiment includes a button portion 2041, a slide 2042, and a second elastic member 2043. The slide 2042 can be restored to its original position by the action of the second elastic member 2043, making operation easier. The slide assembly may not include the second elastic member 2043. The slide 2042 is not limited to being restored to its original position by the action of the second elastic member 2043, but can also be restored to its original position by pulling the slide 2042.

[0066] According to a preferred embodiment, one end of the slide plate 2042 close to the buckle 2031 is a slope structure, and the height of the slope decreases from the direction close to the button portion 2041 to the direction close to the buckle 2031, such as Figure 9 or Figure 10 Specifically, the angle of the inclined surface is not limited and can be gradually inclined, or can be maintained horizontally after inclining, or can be maintained horizontally before inclining. In the preferred technical solution of this embodiment, the end of the slide plate 2042 near the buckle 2031 is an inclined surface structure, so that when the slide plate 2042 slides into contact with the buckle 2031, the buckle 2031 can be lifted upward along the inclined surface of the slide plate 2042.

[0067] The working principle of the slide plate assembly and the buckle assembly is as follows: when placing the fresh-keeping box 10, the user presses the button part 2041 at the same time, pressing the button part 2041 to apply force to the slide plate 2042 and push the slide plate 2042 to slide in the direction close to the buckle 2031, and the slide plate 2042 contacts the buckle 2031 and lifts the buckle 2031 upward, while the second elastic member 2043 and the first elastic member 2032 are both in an elastically compressed state; when the fresh-keeping box 10 is in contact with the vacuum device 20, stop pressing the button part 2041, and the slide plate 2042 slides in the direction away from the buckle 2031 under the elastic force of the second elastic member 2043 and separates the slide plate 2042 from the buckle 2031, and the buckle 2031 drops under the elastic force of the first elastic member 2032 and is engaged with the first slot 1011. Similarly, when taking out the fresh-keeping box 10 , the user presses the button portion 2041 and lifts the buckle 2031 upward through the slide plate 2042 , so that the buckle 2031 is disengaged from the first slot 1011 , thereby allowing the fresh-keeping box 10 to be pulled out.
