[0024] The utility model discloses a kind of gas valve vacuum indication high-temperature-resistant preservation box mainly applied to the scene that whether preservation box is in sealed state cannot be observed.
[0025] Referring to Figure 1 Figure 3 A kind of gas valve vacuum indication high-temperature-resistant preservation box, including box body 1, the opening of the box body 1 is movably connected with sealing cover 3, the shaft center of the upper surface of the sealing cover 3 is penetrated with exhaust mechanism 5, the exhaust mechanism 5 includes fixed plate 51, the shaft center of the upper surface of the sealing cover 3 is penetrated with the fixed plate 51, the inner wall of the fixed plate 51 is fixedly connected with limit tube 53, the inner cavity of the limit tube 53 is slidably connected with sliding ring 54, the inner ring of the sliding ring 54 is fixedly connected with communication pipe 56, the top of the outer surface of the communication pipe 56 is fixedly connected with disc 58, by setting box body 1, the food needing storage can be placed, by setting sealing cover 3, the opening of the box body 1 can be closed, and the edge side of sealing cover 3 can be in contact with the inner wall of box body 1 when pressing, to increase the sealing property between sealing cover 3 and box body 1, the edge side of sealing cover 3 is of silica gel material, and has certain camber, can be in close contact with the inner wall of box body 1 when pressing, by setting exhaust mechanism 5, the air in the inner cavity of box body 1 can be extruded after sealing cover 3 is closed to box body 1, and negative pressure is generated in the inner cavity of box body 1 after extrusion, to increase the sealing property between sealing cover 3 and box body 1, by setting limit tube 53, sliding ring 54 can be limited, so that sliding ring 54 can drive disc 58 to generate the effect of vertical up-and-down movement.
[0026] Referring to Figure 1 And Figure 2 In a preferred embodiment, the box body 1 is made of smooth glass, the sealing cover 3 is made of plastic, the edge side of the lower surface of the sealing cover 3 is fixedly connected with the first sealing ring 4, and the first sealing ring 4 is adapted to rub against the inner wall of the box body 1. By providing the first sealing ring 4, the sealing property between the box body 1 and the sealing cover 3 can be improved when they are connected together, and the gap between the box body 1 and the sealing cover 3 can be further reduced.
[0027] Referring to Figure 1 ,Figure 3 And Figure 4 In a preferred embodiment, the outer ring of the sliding ring 54 is fixedly connected with a second sealing ring 55, which is frictionally matched with the inner wall of the limiting tube 53. By arranging the second sealing ring 55, the sealing between the sliding ring 54 and the inner wall of the limiting tube 53 can be increased, so as to prevent external air from entering the inner cavity of the box body 1 through the gap between the sliding ring 54 and the limiting tube 53. The lower surface of the sealing cover 3 is fixedly connected with a sealing ring 52. The bottom of the outer surface of the communication tube 56 is fixedly connected with a circular film 57, which is fixedly connected to the inner wall of the sealing ring 52. By arranging the circular film 57, the air in the inner cavities of the box body 1 and the sealing cover 3 can be extruded when the communication tube 56 moves downward. The inner cavity of the communication tube 56 is slidingly connected with a tapered plug column 59.

By arranging the tapered plug column 59 and the silica gel sleeve 510, the tapered plug column 59 and the silica gel sleeve 510 can move upward when the circular film 57 moves downward to extrude the air in the inner cavities of the box body 1 and the sealing cover 3, so as to discharge the gas from the gap. The upper surface of the tapered plug column 59 is fixedly connected with a spring 511, the top end of which is fixedly connected to the top surface of the inner cavity of the communication tube 56. By arranging the spring 511, the tapered plug column 59 can be extruded after moving upward, so as to restore the original position of the tapered plug column 59 and protect the sealing of the inner cavity.
[0028] Working principle: when in use, the operator places the food to be stored in the inner cavity of the box body 1, then places the sealing cover 3 at the opening of the box body 1 and presses the sealing cover 3, so that the first sealing ring 4 and the side of the sealing cover 3 tightly contact with the inner wall of the box body 1. Then the operator presses the disc 58. When the disc 58 drives the communication tube 56 to move downward, the circular film 57 extrudes the air in the inner cavity, so as to extrude the air to the tapered plug column 59, which is then discharged from the communication tube 56. Then the tapered plug column 59 reseals the communication tube 56, so as to generate negative pressure in the inner cavities of the box body 1 and the sealing cover 3. At this time, the disc 58 contacts with the fixed plate 51. When the inner cavity of the box body 1 is no longer sealed, the external air enters the inner cavity of the box body 1, which makes the circular film 57 rebound, so as to move the disc 58 upward.
[0029] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. According to the technical solution and the inventive concept of the present application, equivalent replacement or change should be covered in the protection scope of the present application.
