[0040] Reference Figures 2 to 4 The embodiment of the utility model provides a sealing ring, which includes an annular body 21, a sealing outer edge 22 and a sealing inner ring 23.

[0041] The sealing outer edge 22 is an outer edge extending outwardly along the top surface of the annular body 21 .

[0042] The sealing inner ring 23 is arranged on the inner side of the lower part of the annular body 21 along the circumference of the annular body 21 , the bottom of the sealing inner ring 23 is connected to the bottom of the annular body 21 , and the outer wall of the sealing inner ring 23 has a preset distance from the inner wall of the annular body 21 .

[0043] In one embodiment, referring to Figure 2 and Figure 4 The outer end surface of the sealing outer edge 22 is an arc surface 22a.

[0044] In one embodiment, the annular body 21 , the sealing outer edge 22 , and the sealing inner ring 23 are all made in one piece.

[0045] In one embodiment, the annular body 21 , the sealing outer edge 22 and the sealing inner ring 23 are all made of silicone, so that the sealing ring 2 forms a silicone sealing ring.

[0046] In one embodiment, referring to Figure 3 The outer diameter A11 of the sealing outer edge 22 is 84 mm to 85 mm, preferably 84.6 mm.

[0047] The outer diameter A12 of the sealing inner ring 23 is 74 mm to 75 mm, preferably 74.1 mm.

[0048] The inner diameter A13 of the sealing inner ring 23 is 63 mm to 64 mm, preferably 63.6 mm.

[0049] In one embodiment, referring to Figure 4 The overall height A21 of the sealing ring 2 is 18.5 mm to 19.5 mm, preferably 18.8 mm.

[0052] In one embodiment, referring to Figure 4 The bottom surface of the annular body 21 is flush with the bottom surface of the sealing inner ring 23 .

[0053] Reference Figures 5 to 7 The embodiment of the utility model provides a cover body 3, which includes a cover body 31, a cover body inner edge 32, a cover body outer edge 33 and a sealing ring. A circle of first annular grooves 34 with an opening facing downward is formed between the cover body inner edge 32 and the cover body outer edge 33. A circle 35 is circumferentially arranged on the outer peripheral wall of the cover body inner edge 32. A circle of second annular grooves 36 with an opening facing downward is formed between the cover body inner edge 32 and the connecting ring 35.

[0060] In one embodiment, referring to Figure 7 The thickness B12 of the transition plane 37 is 1.5 mm to 2.5 mm, preferably 2 mm.

[0061] Of course, the thickness of the inner edge 32 of the cover body and the thickness of the outer edge 33 of the cover body may be the same as or different from the thickness B12 of the transition plane 37 .

[0062] In one embodiment, referring to Figure 7 The inner edge 32 of the cover body extends upward and outward along the upper surface of the cover body 31 , the top of the inner edge 32 of the cover body is connected to the top of the outer edge 33 of the cover body, and the outer edge 33 of the cover body is located outside the inner edge 32 of the cover body.

[0063] Reference Figure 8 and Fig. 9 An embodiment of the utility model provides a vacuum storage tank 4, which includes a tank body 41 and a cover body. The cover body adopts the cover body 3 provided by the utility model. The tank mouth 411 of the tank body 41 is located in the first annular groove 34, and the side wall of the tank mouth 411 of the tank body 41 is located on the outside of the annular body 21 and the top is located on the lower side of the sealing outer edge 22.

[0064] The tank body 41 and the cover body 3 of the utility model can achieve a better multiple sealing effect under the cooperation of the sealing ring 2.

[0065] Of course, the vacuum storage tank 4 also includes an air extraction component and a pressure relief component arranged on the cover body 3. The air extraction component and the pressure relief component are prior arts and will not be described in detail here.

[0066] In one embodiment, referring to Fig. 9 The bottom surface of the tank body 41 is a plane. When multiple vacuum storage tanks 4 are stacked, the bottom surface of the plane fits with the transition plane 37, and the stacking is more stable.
