Detailed Description
The following examples illustrate the utility model, but the utility model is not limited to these examples. Modifications and equivalents of some of the technical features of the specific embodiments of the present utility model may be made without departing from the spirit of the present utility model, and they are all included in the scope of the claimed utility model.
Embodiment one: as shown in fig. 1, 2 and 3, the present embodiment provides a sealing cover for a vacuum storage container, including a cover body 1 and a silica gel plug 2, wherein a through hole 100 is formed in the center of the cover body 1, the silica gel plug 2 includes a central column 21, an annular turning plate 22 extending from the upper end of the central column 21 to the outside, and a protruding portion 23 extending from the lower end of the central column 21 to the outside, the central column 21 is movably disposed in the through hole 100, an air flow channel 101 is formed between the central column 21 and the inner wall of the through hole 100, the annular turning plate 22 may be pressed on the top surface of the cover body 1, and the protruding portion 23 may be pressed on the bottom surface of the cover body 1.
The sealing cover for the vacuum storage container is simple in structure and can improve the use experience of a user.
Specifically, when the vacuum is required, the suction nozzle of the vacuum device is sucked on the annular turning plate 22, and in the vacuum process, the container in the vacuum storage container can be discharged outwards through the air flow channel 101, the annular turning plate 22 and the gap between the top surfaces of the cover body 1. In the process of vacuumizing, the whole silica gel plug 2 continuously sinks. After the evacuation is completed, the annular flap 22 is tightly pressed against the top surface of the cover 1 due to the internal and external pressure difference of the vacuum storage container, thereby completing the sealing of the through hole 100. And because the annular turning plate 22 is pressed on the top surface of the cover body 1 by means of external atmospheric pressure, the sealing effect is good, the air leakage phenomenon is not easy to occur, the vacuum and storage effect of the vacuum storage container is ensured, and the use experience of a user is better.
When pressure relief is needed, the edges of the ring-shaped turning plate 22 are broken off by hand so that a gap is formed between the ring-shaped turning plate 22 and the top surface of the cover body 1, the gap is communicated with the air flow channel 101, and external air enters the vacuum storage container through the gap between the ring-shaped turning plate 22 and the top surface of the cover body 1 and the air flow channel 101, thereby pressure relief is completed. The user can break off the edge of the ring-shaped turning plate 22 to finish pressure relief with less effort, and the user experience is better.
In this embodiment, a recess portion 210 extending along an axial direction is provided on an outer surface of the central column 21, an upper end of the recess portion 210 is communicated with a groove portion 220 formed on a bottom surface of the annular turning plate 22, the protruding portions 23 include a plurality of protruding portions and are distributed at intervals along a circumferential direction, and a lower end of the recess portion 210 is communicated with a gap between adjacent protruding portions 23.
When the vacuum pumping is needed, the suction nozzle of the vacuum pumping device is sucked on the annular turning plate 22, and in the vacuum pumping process, the container in the vacuum storage container can be discharged outwards through the gaps between the adjacent convex parts 23, the concave parts 210 and the concave groove parts 220. In the process of vacuumizing, the whole silica gel plug 2 continuously sinks. After the evacuation is completed, the annular flap 22 is tightly pressed against the top surface of the cover 1 due to the internal and external pressure difference of the vacuum storage container, thereby completing the sealing of the through hole 100.
When pressure relief is required, the edges of the ring-shaped turning plate 22 are broken off by hand to leak out of the groove part 220, and external air enters the vacuum storage container through the gaps among the groove part 220, the concave part 210 and the adjacent convex parts 23, thereby completing the pressure relief.
In this embodiment, a raised portion 211 protruding from the top surface of the annular flap 22 is disposed at the top of the central column 21, the raised portion 211 is hemispherical and is hollow, and an inner cavity 212 with an open bottom is disposed in the central column 21. After the vacuum pumping is completed, if the vacuum container is kept in a normal vacuum state, the bulge 211 should be in a flattened state due to the internal and external pressure difference of the vacuum container. If the bulge 211 bulges, it is proved that the vacuum storage container has air leakage, and the vacuum state in the vacuum storage container is abnormal, so that the user needs to perform vacuumizing work. The user can intuitively know the vacuum condition in the vacuum storage container through the arranged bulge 211, and the vacuum pumping work can be performed timely.
Further, be provided with the open annular mounting groove 102 in top on the top surface of through-hole 100 periphery the lid 1 be provided with the swivel becket 3 rotationally in the annular mounting groove 102 be provided with the instruction sign 31 on the swivel becket 3 be provided with along circumference interval distribution's time sign 103 on the top surface of swivel becket 3 periphery the lid 1, its simple structure is convenient for the user through above-mentioned design and times, perhaps statistics food's storage time does benefit to the use experience that promotes the user.
Still further the lid 1 overcoat is equipped with silica gel circle 4, silica gel circle 4 includes seal lip 401 and lower seal lip 402, the inboard end of seal lip 401 and the inboard end of seal lip 402 links together down, and its simple structure, reasonable in design does benefit to the leakproofness of promoting the connection between lid 1 and the vacuum storing container through adopting above-mentioned silica gel circle 4.
Embodiment two: as shown in fig. 4 and 5, the present embodiment provides a sealing cover for a vacuum storage container, which is different from the first embodiment in that: the central column 21 has a conical structure with a large upper part and a small lower part, and the convex parts 23 comprise a plurality of convex parts and are distributed at intervals along the circumferential direction.
When the vacuum is needed, the suction nozzle of the vacuum device is sucked on the annular turning plate 22, and in the vacuum process, the container in the vacuum storage container can be discharged outwards through the gaps between the adjacent convex parts 23, the air flow channel 101 and the gaps between the annular turning plate 22 and the top surface of the cover body 1. In the process of vacuumizing, the whole silica gel plug 2 continuously sinks. After the vacuum pumping is completed, the upper portion of the silicone rubber stopper 2 is tightly plugged in the through hole 100 due to the internal and external pressure difference of the vacuum storage container, and the annular turning plate 22 is tightly pressed on the top surface of the cover body 1, thereby completing double sealing of the through hole 100.
Embodiment III: as shown in fig. 6, the present embodiment provides a sealing cover for a vacuum storage container, which is different from the first embodiment in that: the connection part of the inner side end of the upper sealing lip 401 and the inner side end of the lower sealing lip 402 is provided with a cone-shaped structure 403 extending downwards, when the vacuum pumping is completed, the sealing cover presses the top of the vacuum storage container, and the silica gel ring 4 presses the opening of the top of the vacuum storage container, so that the double sealing effect is achieved.
What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
