[0035] Please refer to Figure 1 The present application provides a fresh-keeping box assembly 100, which comprises a fresh-keeping box 20 and a modified atmosphere film assembly 30.

[0036] The fresh-keeping box 20 is provided with a storage space 24 having a first opening, and the gas adjusting film assembly 30 is arranged outside the storage space 24 and includes a gas adjusting film 31 capable of being stretched to cover the first opening of the storage space 24.

[0037] Exemplarily, the fresh-keeping box 20 is a drawer.

[0038] It should be noted that, by arranging the gas adjusting film 31 to cover the first opening of the fresh-keeping box 20, the gas adjusting film 31 can be used to adjust the gas composition (such as oxygen and carbon dioxide) in the storage space 24 of the fresh-keeping box 20 to control the respiration of food (such as meat, fruits and vegetables), thereby delaying the physiological metabolism process and prolonging the storage period of the food.

[0039] The fresh-keeping box assembly 100 provided by the embodiment of the present application can cover the first opening of the storage space 24 by stretching the gas adjusting film 31 (as shown in Figure 6 At this time, the internal gas of the storage space 24 needs to exchange with the external environment via the gas adjusting film 31, that is, the gas adjusting function of the gas adjusting film 31 can be used to improve the fresh-keeping function of the storage space 24 for specific food, so that the color and taste of the food placed in the storage space 24 remain relatively stable and the shelf life is prolonged, thereby improving the user experience; when the gas adjusting film 31 is not needed, the gas adjusting film 31 can also be retracted (as shown in Figure 7 At this time, the first opening of the storage space 24 is in communication with the external environment, and the gas in the storage space 24 can directly exchange with the external environment, thereby changing the fresh-keeping performance of the storage space 24.

[0040] Exemplarily, the gas adjusting film assembly 30 further includes a winding assembly, the gas adjusting film 31 is wound on the winding assembly, and the gas adjusting film 31 has a fixed end and a free end 311 arranged oppositely, wherein the fixed end is connected with the winding assembly, and the gas adjusting film 31 can be stretched or retracted by the movement of the free end 311.

[0041] It can be understood that, by arranging the winding assembly, the gas adjusting film 31 can be retracted and wound on the winding assembly when it is not needed, and the gas adjusting film 31 can be pulled out to be unfolded to cover the first opening of the storage space 24 when it is needed.

[0042] Exemplarily, the winding assembly includes at least one clockwork spring, and the fixed end of the gas adjusting film 31 is connected with the clockwork spring.

[0043] Exemplarily, the number of the clockwork springs can be multiple, and the multiple clockwork springs are arranged in sequence, and each of the multiple clockwork springs is connected with the gas modulation film 31. Wherein, multiple refers to two or more than two, for example, three, four, five, six, seven, eight, and the like.

[0044] It can be understood that, by arranging the clockwork spring and connecting the fixed end of the gas modulation film 31 with the clockwork spring, when the gas modulation film 31 is pulled out, the elastic potential energy is accumulated in the clockwork spring. When it is needed to retract the gas modulation film 31, since the elastic potential energy is stored in the clockwork spring, the contraction force is generated, which acts on the gas modulation film 31, so that the gas modulation film 31 is retracted and wound on the winding assembly. The contraction force of the clockwork spring continues to act until the gas modulation film 31 is completely wound on the winding assembly, at which time the clockwork spring returns to the initial state, and the elastic potential energy is released.

[0045] Please refer to Figure 4 and Figure 5 , the gas modulation film assembly 30 further comprises a shell 33, the winding assembly and at least a part of the gas modulation film 31 are arranged in the shell 33, the shell 33 has a second opening, and the free end 311 of the gas modulation film 31 extends out of the second opening.

[0046] Exemplarily, the shell 33 is in a cylindrical shape.

[0047] It can be understood that, by arranging the shell 33, the winding assembly and at least a part of the gas modulation film 31 are arranged in the shell 33, so that the winding assembly and the gas modulation film 31 are protected. By arranging the second opening on the shell 33, the gas modulation film 31 can extend out of or retract into the second opening.

[0048] Please refer to Figure 1 and Figure 4 , the fresh-keeping box assembly 100 further comprises a first fixing member 41 and a second fixing member 42, and the first fixing member 41 and the second fixing member 42 are respectively detachably connected with the fresh-keeping box 20.

[0050] Exemplarily, the first recess can be a groove or a through hole, and the second recess can be a groove or a through hole.

[0051] It can be understood that by arranging the first fixing member 41 and the second fixing member 42, the gas modulation film assembly 30 can be supported, and when the gas modulation film assembly 30 needs to be replaced, the first fixing member 41 and the second fixing member 42 can be disassembled to replace the gas modulation film assembly 30.

[0053] Exemplarily, scenarios in which the gas modulation film assembly 30 needs to be replaced include: 1. The gas modulation function of the gas modulation film 31 is weakened or lost; 2. The gas modulation film 31 is damaged; and 3. The type of food in the storage space 24 is changed, so that a specific type of gas modulation film 31 needs to be used.

[0054] It should be noted that different food materials have different requirements for the gas modulation film 31, and the respiration characteristics (including respiration rate and respiration quotient) of different food materials are different, so the gas composition in the fresh-keeping space will also be different within the same time, and the oxygen concentration and carbon dioxide concentration will also be different, so the same film should be used for the same type of food to obtain the best gas modulation fresh-keeping effect.

[0055] Exemplarily, the gas modulation film 31 includes at least one of a fruit gas modulation film, a vegetable gas modulation film, a mushroom gas modulation film, and a dry goods gas modulation film.
