DETAILED DESCRIPTION

[0030] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The present invention provides a fresh-keeping container 100 and a low-temperature fresh-keeping device, wherein the pressure relief hole 213 thereof can avoid being blocked by objects, thereby achieving a pressure relief effect of the fresh-keeping container 100 and improving the convenience of taking and placing by users.

[0032] like Figures 1 to 6 As shown, according to the fresh-keeping container 100 of the embodiment of the present invention, the fresh-keeping container 100 includes a barrel assembly 10 , a drawer assembly 20 and a blocking member 30 .

[0033] Among them, the barrel body assembly 10 has a storage cavity 12 with a front opening 11, and the drawer assembly 20 can be pulled out and passed through the storage cavity 12, and is used to open and close the opening 11. The drawer assembly 20 has a storage cavity 211 and a pressure relief hole 213. When the drawer assembly 20 closes the opening 11, the storage cavity 211 is arranged in the storage cavity 12, and the pressure relief hole 213 is connected to the storage cavity 12 and is arranged outside the storage cavity 211. The blocking member 30 can be opened to block the pressure relief hole 213; in this way, the pressure relief hole 213 can be avoided from being blocked by objects, and the pressure relief effect of the fresh-keeping container 100 can be achieved, thereby improving the convenience of users in taking and putting.

[0034] Specifically, when it is necessary to open the fresh-keeping container 100, the storage chamber 12 is constructed into a negative pressure area in order to achieve the fresh-keeping effect. At this time, the user can open the pressure relief hole 213 through the blocking member 30, so that the air pressure of the storage chamber 12 is balanced with that of the external environment. Then, the user can draw the drawer from the storage chamber 12 through the drawer assembly 20, thereby opening the opening 11 of the storage chamber 12, making it convenient for the user to take out the items in the storage chamber 211; wherein, the pressure relief hole 213 is connected to the storage chamber 12, but the pressure relief hole 213 is arranged outside the storage chamber 211. In this way, when the user relieves the pressure of the storage chamber 12, it can avoid that the food in the fresh-keeping container 100 is blocked by the pressure relief hole 213, resulting in poor pressure relief of the fresh-keeping container 100 and affecting the taking and placing of items. In other words, according to the fresh-keeping container 100 of the embodiment of the present invention, its pressure relief hole 213 can avoid being blocked by items, thereby achieving the pressure relief effect of the fresh-keeping container 100 and improving the convenience of taking and placing for users.

[0035] like Figures 2 to 4 As shown, in some embodiments of the present invention, the drawer assembly 20 is provided with a drawer guide rail 23, which extends in the front-to-back direction. The drawer guide rail 23 can guide the drawer assembly 20 to move in the front-to-back direction relative to the barrel body assembly 10, thereby improving the smoothness of the drawer assembly 20 opening the barrel body assembly 10, thereby improving the user experience.

[0036] In addition, the pressure relief hole 213 has a first end and a second end relative to each other. The first end of the pressure relief hole 213 is connected to the storage chamber 12 and is arranged below the drawer guide rail 23. In this way, the pressure relief hole 213 can be hidden below the drawer guide rail 23, which increases the aesthetics. The pressure relief hole 213 can be blocked by the drawer guide rail 23 to prevent dust and the like from clogging the pressure relief hole 213, thereby ensuring that the fresh-keeping container 100 has good opening and closing performance; the second end of the pressure relief hole 213 can cooperate with the sealing member 30, and the sealing member 30 can open and block the pressure relief hole 213 to achieve pressure relief of the storage chamber 12 and isolation of the storage chamber 12 from the external environment, thereby improving the sealing performance of the storage chamber 12.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the first end of the pressure relief hole 213 is connected to the storage cavity 12, wherein the first end of the pressure relief hole 213 is arranged at the lower part of the front end of the drawer assembly 20. It can be understood that the opening 11 of the storage cavity 12 is arranged in front of the barrel body assembly 10. Therefore, the first end of the pressure relief hole 213 can be set at the front end of the drawer assembly 20, which can shorten the pressure relief path of the storage cavity 12, so that the storage cavity 12 can be quickly depressurized, which is convenient for the user to open the storage cavity 12 and improve the user's usage experience; in addition, the top of the storage cavity 211 of the drawer assembly 20 is open, and the top of the storage cavity 211 can facilitate the user to take and put items, but in order to avoid solids, liquids and other items in the storage cavity 211 affecting the pressure relief performance of the pressure relief hole 213, the first end of the pressure relief hole 213 can be set at the lower part of the drawer assembly 20 to improve the pressure relief performance of the pressure relief hole 213.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, when the drawer assembly 20 closes the opening 11, the first end of the pressure relief hole 213 is spaced apart from the inner bottom surface of the storage cavity 12 by a predetermined distance; it can be understood that in the fresh-keeping container 100, a low-pressure and low-temperature method can be used for preservation. After the drawer assembly 20 opens the storage cavity 12, due to the temperature difference between the inside and outside of the storage cavity 12, liquid accumulation will form in the storage cavity 12. Therefore, in order to avoid the accumulated liquid blocking the pressure relief hole 213 and affecting the pressure relief of the storage cavity 12, the first end of the pressure relief hole 213 can be spaced apart from the inner bottom surface of the storage cavity 12 by a predetermined distance when the drawer assembly 20 closes the opening 11, thereby improving the pressure relief effect of the storage cavity 12.

[0039] like Figures 2 to 4As shown, in some embodiments of the present invention, the drawer assembly 20 includes a drawer body 21, a storage cavity 211 is provided in the drawer body 21, and the front edge of the drawer body 21 is provided with a flange 212 extending outward from the storage cavity 211 in the left and right directions, and the first end of the pressure relief hole 213 passes through the flange 212; in this way, the items in the storage cavity 211 can be prevented from affecting the pressure relief hole 213, and the structural strength of the drawer assembly 20 can be improved.

[0040] It can be understood that the drawer assembly 20 includes a drawer body 21 and a flange 212, the storage cavity 211 is arranged in the drawer body 21, the flange 212 is arranged on the front edge of the drawer body 21, and extends toward the outside of the storage cavity 211 in the left and right directions, and the pressure relief hole 213 is arranged in the flange 212. In this way, the pressure relief hole 213 can be located at a position on the drawer assembly 20 away from the storage cavity 211, thereby avoiding the objects in the storage cavity 211 from blocking the pressure relief hole 213, causing poor pressure relief of the pressure relief hole 213; and the flange 212 is connected to the drawer body 21, which can improve the structural strength of the drawer assembly 20, so that the fresh-keeping container 100 can still maintain good structural stability in a low-pressure environment, thereby improving the fresh-keeping effect of the fresh-keeping container 100.

[0041] like Figures 2 to 4 As shown, in some embodiments of the present invention, the side wall of the drawer body 21 is provided with a drawer guide 23, which extends in the front-to-back direction. The drawer guide 23 can cooperate with the inner wall surface of the storage cavity 12, thereby guiding the drawer assembly 20 to move relative to the barrel body assembly 10 in the front-to-back direction; for example, the inner wall surface of the storage cavity 12 can be provided with a guide groove, which extends in the front-to-back direction, and the drawer guide 23 can be slidably set in the guide groove in the front-to-back direction, thereby guiding the drawer assembly 20 to smoothly open and close the storage cavity 12 of the barrel body assembly 10.

[0042] Furthermore, the front end of the drawer guide 23 is connected to the flange 212, thereby further improving the structural strength of the drawer assembly 20; and the first end of the pressure relief hole 213 is arranged at a position lower than the flange 212 of the drawer guide 23; in this way, the pressure relief hole 213 can be blocked by the drawer guide 23, thereby improving the appearance of the fresh-keeping container 100 and preventing dust and the like from clogging the pressure relief hole 213.

[0043] like Figures 2 to 5 As shown, Figure 5Partial structure of the blocking piece 30 is shown. In some embodiments of the present invention, the drawer assembly 20 also includes a drawer body 21 and a drawer panel 22. The storage cavity 211 is provided in the drawer body 21. The drawer panel 22 is connected to the front end of the drawer body 21 and is configured to open and close the opening 11. The second end of the pressure relief hole 213 passes through the front surface of the drawer panel 22. This configuration makes it easier for the user to drive the blocking piece 30 to achieve pressure relief in the storage cavity 12, thereby improving convenience.

[0044] Specifically, in combination with the above, the drawer body 21 is provided with a flange 212, which can be connected to the drawer panel 22 to increase the contact area between the drawer body 21 and the drawer panel 22, thereby improving the connection strength; and the second end of the pressure relief hole 213 passes through the front surface of the drawer panel 22, which can facilitate the user to relieve pressure on the storage cavity 12 from the front side of the fresh-keeping container 100, thereby improving convenience; when the storage cavity 12 needs to be opened, the user can drive the blocking member 30 from the front side of the fresh-keeping container 100 to open the second end of the pressure relief hole 213. At this time, the external atmosphere can enter the storage cavity 12 along the second end of the pressure relief hole 213 and the first end of the pressure relief hole 213 to balance the pressure inside and outside the storage cavity 12. Then the user can drive the drawer panel 22 to pull the drawer body 21 out of the storage cavity 12 to open the storage cavity 12. Similarly, when the storage chamber 12 needs to be closed, the user can drive the drawer panel 22 to close the opening 11 of the storage chamber 12, and before or after the drawer panel 22 closes the storage chamber 12, drive the blocking member 30 to close the second end of the pressure relief hole 213, thereby cutting off the connection between the closed storage chamber 12 and the external environment, realizing the closure of the storage chamber 12, and facilitating the subsequent construction of a low-temperature and low-pressure environment in the storage chamber 12.

[0045] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the drawer assembly 20 also includes a handle 50, which is movably connected to the drawer panel 22 and has a first position and a second position. The blocking member 30 is provided on the handle 50, and the blocking member 30 blocks the pressure relief hole 213 in the first position and opens the pressure relief hole 213 in the second position; in this way, the pressure relief and closure of the storage cavity 12 can be achieved through the handle 50, and it is convenient to drive the drawer assembly 20 to open and close the opening 11.

[0046] Specifically, the handle 50 is connected to the drawer panel 22. The user can hold and drive the handle 50 to pull the drawer panel 22 out of the barrel assembly 10 or push it into the barrel assembly 10, thereby improving the user's convenience. The blocking member 30 is provided on the handle 50. The handle 50 has a first position and a second position. The user can drive the handle 50 to move relative to the drawer panel 22 to switch to the first position. At this time, the blocking member 30 blocks the pressure relief hole 213, and the drawer panel 22 closes the opening 11 of the storage chamber 12, thereby facilitating the construction of a low-pressure and low-temperature environment in the storage chamber 12. The user can drive the handle 50 to move relative to the drawer panel 22 to switch to the second position. At this time, the blocking member 30 opens the pressure relief hole 213 to balance the pressure inside and outside the storage chamber 12, thereby facilitating the user to open the storage chamber 12. In short, the blocking member 30 is provided on the handle 50. The handle 50 can facilitate the user to drive the movement of the drawer panel 22 and facilitate the opening and closing of the pressure relief hole 213, thereby improving convenience.

[0047] In addition, in some specific examples of the present invention, the handle 50 can be rotatably connected to the drawer panel 22 and rotate between a first position and a second position to open and block the pressure relief hole 213; or, the handle 50 can be slidably connected to the drawer panel 22 and slide between a first position and a second position to open and block the pressure relief hole 213; of course, the scope of protection of the present invention includes but is not limited to the aforementioned examples.

[0048] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, the fresh-keeping container 100 also includes a bracket 40, which is rotatably connected to the drawer assembly 20 and has a locking position for locking the drawer assembly 20 to the barrel assembly 10 and an unlocking position for releasing the lock on the drawer assembly 20, wherein the handle 50 is connected to the bracket 40 and is configured to drive the handle 50 to rotate; in this way, the drawer assembly 20 can be locked and unlocked by the handle 50, thereby improving convenience; and the bracket 40 can improve the sealing performance of the fresh-keeping container 100, thereby improving the fresh-keeping effect of the fresh-keeping container 100.

[0049] Specifically, in combination with the above, the handle 50 has a first position and a second position. The first position of the handle 50 corresponds to the locked position of the bracket 40, and the second position of the handle 50 corresponds to the unlocked position of the bracket 40. When the storage cavity 12 needs to be opened, the user can hold the handle 50 to drive the bracket 40 to move from the locked position to the unlocked position, so that the drawer assembly 20 is unlocked and the pressure relief hole 213 is opened to relieve the pressure of the storage cavity 12. At this time, the drawer assembly 20 can be driven by the handle 50 to open the storage cavity 12. When the storage cavity 12 needs to be closed, the user drives the drawer assembly 20 to close the storage cavity 12 through the handle 50. , and drives the bracket 40 to move from the unlocked position to the unlocked position, so that the drawer assembly 20 is locked in the barrel body assembly 10, and the pressure relief hole 213 is blocked to facilitate the subsequent construction of a low-temperature and low-pressure environment in the storage cavity 12; therefore, by the provision of the bracket 40, the sealing performance of the fresh-keeping container 100 can be improved, thereby improving the fresh-keeping effect of the fresh-keeping container 100; and the handle 50 is connected to the bracket 40, and the handle 50 is connected to the blocking member 30, and the handle 50 can be used to drive the bracket 40 to lock and unlock the drawer assembly 20, and drive the blocking member 30 to open and block the pressure relief hole 213, thereby improving convenience.

[0050] like Figure 1 As shown, in some embodiments of the present invention, the handle 50 is configured to be a long strip extending in the left-right direction. This configuration can increase the user's gripping area and facilitate the user to drive the handle 50.

[0051] Furthermore, the left and right ends of the handle 50 are connected to brackets 40, and the bracket 40 on the left side of the handle 50 is rotatably connected to the left side of the drawer panel 22, and the bracket 40 on the right side of the handle 50 is rotatably connected to the right side of the drawer panel 22; in this way, the movement stability of the handle 50 can be improved. When driving the handle 50 to move, the brackets 40 at the left and right ends of the handle 50 can disperse the force applied to the handle 50, so that the handle 50 can operate more stably.

[0052] like Figure 1 As shown, in some embodiments of the present invention, the bracket 40 is rotatably connected to the middle area of ​​the drawer panel 22 along the up and down directions, and the handle 50 is arranged at the upper or lower part of the front of the drawer panel 22; this arrangement can ensure the range of movement of the handle 50 and improve the efficiency of use.

[0053] For ease of understanding, the handle 50 is provided on the front side of the lower portion of the panel as an example for explanation:

[0054] It is understood that if the bracket 40 is rotatably connected to the upper region of the drawer panel 22 along the vertical direction, when the user drives the bracket 40 to rotate via the handle 50, the range of motion of the bracket 40 is too large, making it inconvenient for the user to drive the handle 50 to rotate; if the bracket 40 is rotatably connected to the lower region of the drawer panel 22 along the vertical direction, when the user drives the bracket 40 to rotate via the handle 50, the range of motion of the bracket 40 is too small, and the distance between the locked position and the unlocked position of the bracket 40 is small, which is prone to misoperation and affects the use of the fresh-keeping container 100. Therefore, the bracket 40 can be rotatably connected to the middle region of the drawer panel 22 along the vertical direction to ensure the range of motion of the handle 50 and improve the efficiency of use.

[0055] It should be noted that the bracket 40 is rotatably connected to the middle area of ​​the drawer panel 22 along the up and down directions. It can be understood that the rotational connection point between the bracket 40 and the drawer panel 22 is closer to the middle relative to the upper or lower part of the drawer panel 22.

[0056] like Figure 5 As shown, in some embodiments of the present invention, the barrel body assembly 10 is provided with an exhaust port 60 for connecting to an exhaust device, and the exhaust port 60 is connected to the storage cavity 12. The exhaust port 60 can be connected to an external exhaust device. The exhaust device extracts the gas in the storage cavity 12 to form a low-pressure environment in the storage cavity 12. At this time, the bacteria and other organisms in the storage cavity 12 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 12; optionally, a vacuum environment can be created in the storage cavity 12 through the exhaust port 60 to further improve the preservation effect of the fresh-keeping container 100.

[0057] like Figure 5 As shown, in some embodiments of the present invention, the fresh-keeping container 100 also includes an exhaust component 70, which is connected to the storage cavity 12. The exhaust component 70 can extract the gas in the storage cavity 12 to form a low-pressure environment in the storage cavity 12. At this time, the bacteria and other organisms in the storage cavity 12 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 12.

[0058] like Figures 1 to 6 As shown, according to the low-temperature fresh-keeping device of an embodiment of the present invention, the low-temperature fresh-keeping device includes a body, a refrigeration device and the fresh-keeping container 100 mentioned above.

[0059] Among them, the body is provided with a refrigeration compartment, and the refrigeration device is provided in the body for cooling the refrigeration compartment. The fresh-keeping container 100 is provided in the refrigeration compartment. Through the aforementioned fresh-keeping container 100, it is possible to avoid items blocking the pressure relief hole 213 and causing the pressure to be unable to be relieved, thereby improving the user's convenience in taking and placing.

[0060] Specifically, the fresh-keeping container 100 is placed in a refrigeration room and is cooled in the refrigeration room by a refrigeration device, so that the fresh-keeping container 100 is in a low-temperature environment. In a low-temperature environment, biological activities such as bacteria are reduced, thereby achieving a low-temperature preservation function, and a negative pressure can be created in the storage cavity 12 through the exhaust component 70, thereby achieving a low-pressure preservation function.

[0061] When using the fresh-keeping container 100, the user can hold and flip the handle 50 to drive the bracket 40 to rotate from the locked position to the unlocked position, the drawer panel 22 is unlocked, and the blocking member 30 is driven to rotate to the second position. The blocking member 30 opens the pressure relief hole 213 to balance the pressure inside and outside the storage cavity 12. At this time, the user can drive the drawer panel 22 to open the storage cavity 12 through the handle 50. Then the user can drive the drawer panel 22 to close the storage cavity 12 through the handle 50, and drive the bracket 40 to rotate from the unlocked position to the locked position. At this time, the drawer panel 22 is locked, and the blocking member 30 is driven to rotate to the first position. The blocking member 30 blocks the pressure relief hole 213 to isolate the inside and outside of the storage cavity 12.

[0062] Among them, the drawer body 21 has a storage cavity 211 and is connected to a flange 212. The pressure relief hole 213 can be set at the flange 212, so as to prevent the items in the storage cavity 211 from blocking the pressure relief hole 213, resulting in poor pressure relief and affecting the opening of the storage cavity 12; in addition, the drawer body 21 is connected to a drawer guide rail 23, and the drawer guide rail 23 can cooperate with the inner wall surface of the storage cavity 12 to guide the drawer body 21 to move smoothly in the front and rear directions relative to the barrel body assembly 10, thereby opening and closing the storage cavity 12 and improving the opening and closing stability.
