[0023] Embodiment 1

[0024] See also Figure 1-4 , the utility model provides the following technical solutions:

[0025] Specifically, it refers to a multi-layer glass fresh-keeping bowl, including a fresh-keeping bowl 1, the top of the fresh-keeping bowl 1 is sealed with an irregular sealing ring 2, the top of the irregular sealing ring 2 is snap-fitted with a fixed top frame 3, the inner wall of the fixed top frame 3 is snap-fitted with an irregular sealing frame 4, and the irregular sealing frame 4 is sealed with a glass top cover 5; the top of the glass top cover 5 is provided with an air vent 6, and the top of the glass top cover 5 is snap-fitted with an air vent cover 15 above the air vent 6; the bottom of the irregular sealing ring 2 is provided with a connecting groove 16, and the connecting groove 16 is fixed with sealing rings 17 on both inner side walls; the fresh-keeping bowl 1 is symmetrically provided with circular grooves 7 matched with the sealing ring 17 near the top, and the fresh-keeping bowl 1 is snap-fitted with the connecting groove 16.

[0026] The specific application of this embodiment is as follows: the fixed top frame 3 is a polypropylene plastic frame, the irregular sealing ring 2 and the irregular sealing frame 4 are both made of edible grade rubber. In the process of covering the glass top cover 5 on the fresh-keeping bowl 1, the irregular sealing ring 2 is subjected to the inward and outward forces provided by the fresh-keeping bowl 1, so that the irregular sealing ring 2 is squeezed and relatively flattened, until the sealing ring 17 fixed by the two inner side walls of the connecting groove 16 and the circular groove 7 opened on the inner and outer sides of the fresh-keeping bowl 1 are sealed and engaged with each other, so as to achieve the sealing of the fresh-keeping bowl 1, wherein the irregular sealing ring 2 is provided with a sealing ring 17 fixed by the connecting groove 16 relative to the two inner side walls and the circular groove 7 opened on the inner and outer sides of the fresh-keeping bowl 1. The glass top cover 5 at the center of the sealing frame 4 forms an air seal with the upper and lower surfaces of the glass top cover 5 and the irregular sealing frame 4, thereby achieving safety protection for the glass top cover 5 and sealing the inside of the fresh-keeping bowl 1, improving the sealing of the fresh-keeping bowl 1 and ensuring its fresh-keeping performance. In addition, when it is necessary to open the fresh-keeping bowl 1, the internal air pressure of the fresh-keeping bowl 1 is relatively high and it is not easy to open it. The air release cover 15 that is snap-fitted on the top of the glass top cover 5 can be opened, and the air release port 6 opened on the top of the glass top cover 5 can be used to deflate the fresh-keeping bowl 1, thereby facilitating the opening of the fresh-keeping bowl 1.

[0027] Embodiment 2

[0028] See also Figure 1-4The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a heat preservation barrel 9 is provided at the outer bottom of the fresh-keeping bowl 1, and a plurality of anti-collision strips 10 are provided at the inner bottom of the heat preservation barrel 9; a rectangular limit frame 11 is fixed to the inner wall of the heat preservation barrel 9; a plurality of U-shaped plates 12 are slidably fitted on the rectangular limit frame 11, and a plurality of elastic springs 13 are fixedly connected between the rectangular limit frame 11 and the U-shaped plate 12; a triangular limit frame 8 is fixed to the outer side surface of the fresh-keeping bowl 1; and a triangular limit block 14 that fits the triangular limit frame 8 is fixed to the outer side surface of the plurality of U-shaped plates 12.

[0029] A specific application of the present embodiment is: when the fresh-keeping bowl 1 filled with food needs to be kept warm, a heat-insulating barrel 9 can be installed at the bottom of the fresh-keeping bowl 1 to achieve the purpose of heat preservation. The specific principle is: when the fresh-keeping bowl 1 is directly connected to the heat-insulating barrel 9, the triangular limiting frame 8 fixed on the outer side of the fresh-keeping bowl 1 provides a force to the triangular limiting blocks 14 fixed on one side of the several U-shaped plates 12 to move away from the fresh-keeping bowl 1, so that the several elastic springs 13 fixedly connected between the rectangular limiting frame 11 and the U-shaped plate 12 are compressed until the lower part of the several triangular limiting blocks 14 and the upper part of the triangular limiting frame 8 are in contact with each other, the elastic spring 13 returns to its natural state, and the several anti-collision strips 10 arranged on the bottom of the heat-insulating barrel 9 are in contact with the outer bottom of the fresh-keeping bowl 1 to avoid the collision between the fresh-keeping bowl 1 and the heat-insulating barrel 9. At this time, the installation between the fresh-keeping bowl 1 and the heat-insulating barrel 9 is completed, the heat-insulating performance of the fresh-keeping bowl 1 is improved, and it is convenient for people to use.
