[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-6The utility model provides a technical solution: it includes a box body 1, an upper cover 2 and a film 6 arranged inside the upper cover 2, a vacuum assembly is provided in the box body 1, and is characterized in that: there is a concave structure in the middle of the bottom of the box body 1, the vacuum assembly is arranged in the concave structure, and a round hole is opened on the top of the concave structure, an inner cover 8 is provided above the concave structure, a sponge pad 9 is provided between the inner cover 8 and the concave structure, a hole is opened in the middle of the sponge pad 9, a pressure relief bin 5 is provided on one side of the box body 1, and a switch button 4 is provided on the same side of the box body 1. Since the sponge pad 9 is provided between the inner cover 8 and the concave structure, food residues or other impurities can be effectively filtered to prevent the air pump from being blocked.

[0023] In this example, the vacuum assembly includes a one-way valve, one end of which is arranged in the hole of the sponge pad, and the other end is connected to an air pump. A support frame is provided at the lower part of the other end of the air pump, a battery cover is installed at the lower part of the support frame, and a vent is provided at the bottom of the support frame. The vent is convenient for discharging the gas in the fresh-keeping box.

[0024] In this example, a raised circular structure is provided on the upper outer edge of the box body 1, and a lock buckle 3 is provided on the side of the upper cover 2. The upper cover 2 is covered on the box body 1 through the lock buckle 3 and the circular structure, making it convenient for the upper cover 2 to be buckled on the box body 1.

[0025] In this example, a plurality of inner boxes 7 are provided inside the box body 1. The inner boxes 7 are in a fan-ring structure and can store different foods.

[0026] In this example, a blocking cover 501 is provided on the upper portion of the pressure relief chamber 5 to facilitate extraction of air from the box body and opening of the fresh-keeping box under negative pressure.

[0027] In this example, a battery is installed between the bottom of the support frame 11 and the battery cover 12, which supplies power to drive the air pump to extract the air in the box.

[0028] In this example, the adhesive film 6 is made of silicone material. The adhesive film 6 made of silicone material has good sealing performance and is safe and hygienic.

[0029] In this example, a handle is installed on the top of the upper cover 2 for easy taking.

[0030] Working principle: When using the food preservation box, first install the battery, cover the blocking cover 501, put the food to be preserved into the inner box 7, and close the upper cover 2 with the film 6 on the box body 1 through the lock 3. There is a gap between the box body 1 and the inner box 7, and there is a gap between the inner cover 8 and the concave structure of the box body 1. When the switch button 4 is pressed, the battery and the air pump 10 are connected, and the air pump 10 starts to operate. The air pump 10 extracts the air in the box body 1 and the inner box 7 from the gap, and the air is discharged through the vent at the bottom of the support frame 11. After the air is extracted, press the switch button 4 again, and the air pump 10 Stop working. When it is necessary to open the upper cover 2, it is not easy to open the fresh-keeping box because it is in a negative pressure state. It is necessary to open the blocking cover 501 so that air enters the fresh-keeping box through the pressure relief chamber 5. In this way, the upper cover 2 can be easily opened. Since a sponge pad 9 is provided, when the extracted air is mixed with food residues or other impurities, the sponge pad 9 can filter the food residues or other impurities when passing through the sponge pad 9, and no impurities will enter the air pump, avoiding blockage. In this way, the whole work is completed. The contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
