If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] See also Figure 1-5, the utility model provides a technical solution: a multi-chamber vacuum bag, comprising a first bag body 1 and a second bag body 2, wherein two sides of the first bag body 1 and the second bag body 2 are fused by hot pressing;

[0037] The other two sides of the first bag body 1 and the second bag body 2 are fastened together by a sealing strip;

[0038] A cross-shaped dividing area 3 is fused on the surface of the first bag body 1 and the second bag body 2 by heat pressing, and the dividing area 3 divides the interior of the first bag body 1 and the second bag body 2 into four independent cavities;

[0039] A connecting ring 5 is inlaid at the center of the first bag body 1 and the second bag body 2;

[0040] The connecting ring 5 is threadedly connected with a sealing cap 4;

[0041] The vacuum mechanism is arranged inside the connecting ring 5. Through the vacuum mechanism, vacuum extraction can be performed on different cavities separately. Therefore, vacuum extraction can be performed on the inside of each cavity separately according to the different numbers of four independent cavities used.

[0042] Furthermore, the vacuum mechanism includes an inner valve 6, which is rotatably connected to the inside of the connecting ring 5, and a valve core 11 is fixedly connected to the inside of the inner valve 6;

[0043] An annular built-in rotating groove 10 is provided on the inner wall of the connecting ring 5, and a built-in rotating ring 7 is fixedly connected to the surface of the inner valve 6, and the built-in rotating ring 7 is rotatably connected to the inside of the built-in rotating groove 10;

[0044] A vacuum extraction tube 13 is slidably connected to the internal rotating ring 7, and the other end of the vacuum extraction tube 13 extends to the interior of the internal valve 6;

[0045] A return spring 8 is movably sleeved on the vacuum extraction tube 13, and two ends of the return spring 8 are respectively fixedly connected to the surface of the vacuum extraction tube 13 and the inner wall of the inner valve 6;

[0046] One end of the vacuum extraction tube 13 is in an arc shape, and the other end of the vacuum extraction tube 13 is in a trumpet shape. The trumpet-shaped end of the vacuum extraction tube 13 is located inside the inner valve 6;

[0047] The connecting ring 5 is provided with four vacuum extraction holes 9, which are respectively connected with the four cavities.

[0048] When the cavity needs to be vacuumed, the inner valve 6 is rotated so that the vacuum extraction tube 13 and the corresponding vacuum extraction hole 9 overlap each other. At this time, the vacuum inside the cavity can be extracted by connecting the external vacuum extraction pump to the inner valve 6, thereby ensuring that the food will not rot or deteriorate during storage. At the same time, the four separate cavities can store different types of food or items respectively.

[0049] By setting one end of the vacuum extraction tube 13 to be in an arc shape and providing a reset spring 8, when the inner valve 6 rotates, the vacuum extraction tube 13 is forced to retract into the inner valve 6, and after the vacuum extraction tube 13 overlaps with the vacuum extraction hole 9, it is reset under the action of the reset spring 8, so that the vacuum extraction tube 13 overlaps with the vacuum extraction hole 9, thereby completing the vacuum extraction of the independent cavity;

[0050] By configuring one end of the vacuum extraction tube 13 to be trumpet-shaped, the flow velocity of the air is increased, thereby improving the efficiency of the vacuum extraction.

[0051] Furthermore, four positioning grooves 14 are provided on the connecting ring 5;

[0052] The inner valve 6 is provided with a built-in installation groove 16, and a positioning block 15 is slidably connected inside the built-in installation groove 16;

[0053] One end of the positioning block 15 is arc-shaped;

[0054] An elastic component 17 is fixedly connected inside the built-in mounting groove 16, and the other end of the elastic component 17 is fixedly connected to the positioning block 15;

[0055] When the inner valve 6 rotates, the positioning block 15 is retracted into the inner part of the built-in installation groove 16 through the elastic component 17. When the positioning block 15 overlaps with the positioning groove 14 on the connecting ring 5, the positioning block 15 is inserted into the inner part of the positioning groove 14 through the elastic component 17, thereby fixing the inner valve 6 and preventing the inner valve 6 from rotating randomly during the vacuum extraction process, thereby ensuring that the vacuum extraction tube 13 and the vacuum extraction hole 9 can always overlap.

[0056] At the same time, the setting of the positioning groove 14 and the positioning block 15 can accurately determine the position of the vacuum extraction tube 13. When the positioning groove 14 and the positioning block 15 are engaged, the vacuum extraction tube 13 and the vacuum extraction hole 9 are in an overlapping state, so that the operator can more easily determine the position of the vacuum extraction tube 13 and then perform vacuum extraction on the corresponding cavity.

[0057] Furthermore, a buckle groove 12 is provided on the inner valve 6 to facilitate exerting force thereon;

[0058] Working principle: when the cavity needs to be vacuumed, the inner valve 6 is rotated, and the inner valve 6 rotates so that the vacuum extraction tube 13 and the corresponding vacuum extraction hole 9 overlap each other. At this time, the vacuum inside the cavity can be extracted by connecting the external vacuum extraction pump to the inner valve 6, thereby ensuring that the food will not rot or deteriorate during storage. At the same time, the four separate cavities can store different types of food or items respectively;

[0059] When the inner valve 6 rotates, the vacuum extraction tube 13 is forced to retract into the inner valve 6, and after the vacuum extraction tube 13 overlaps with the vacuum extraction hole 9, it is reset under the action of the reset spring 8, so that the vacuum extraction tube 13 overlaps with the vacuum extraction hole 9, thereby completing the vacuum extraction of the independent cavity;

[0060] When the inner valve 6 rotates, the positioning block 15 is retracted into the interior of the built-in mounting groove 16 through the elastic component 17. When the positioning block 15 overlaps with the positioning groove 14 on the connecting ring 5, the positioning block 15 is inserted into the interior of the positioning groove 14 through the elastic component 17, thereby fixing the inner valve 6 to avoid random rotation of the inner valve 6 during the vacuum extraction process, thereby ensuring that the vacuum extraction tube 13 and the vacuum extraction hole 9 can always overlap.

[0061] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
