[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a vacuum insulated cup with an antibacterial stainless steel structure, comprising an insulated cup body 1 and an inner liner 12. The insulated cup body 1 has an annular mounting groove inside, and the inner liner 12 is disposed in the annular mounting groove. The insulated cup body 1 has openings at both ends. The end of the insulated cup body 1 away from the drinking spout has a base 3. A sealing part 9 protrudes from the center of the base 3 and is inserted into the inner liner 12. A connecting ring 8 is provided on the outside of the sealing part 9 on the base 3. The connecting ring 8 is sleeved on the insulated cup body 1 and threadedly connected to the insulated cup body 1. A heat insulation shell 2 is installed on the outside of the insulated cup body 1. An adjusting ring 4 is threadedly connected to the outside of the insulated cup body 1. A groove is provided on the bottom surface of the insulated cup body 1, and a suction cup 7 is installed in the groove. Multiple positioning components connected to the heat insulation shell 2 are installed on the base 3.

[0023] The thermos has openings at both ends, and the inner liner is detached from the end of the thermos away from the drinking spout, so as not to affect the use of the drinking spout or the subsequent installation of the sealing plug and lid.

[0024] In this embodiment, one end of the annular mounting groove extends into the drinking spout of the thermos cup body 1, and one end of the inner liner 12 narrows inward to form a neck 13. The neck 13 is inserted into the end of the annular mounting groove located inside the drinking spout, and the inner ring surface of the neck 13 is flush with the inner wall of the drinking spout on the thermos cup body 1. A protruding ring 14 is formed on the end face of the neck 13, and an annular groove is provided on the end face of the annular mounting groove opposite to the protruding ring 14. The protruding ring 14 is inserted into the annular groove.

[0025] In this embodiment, an antibacterial coating is provided on the inner wall surface of the inner liner 12, and multiple positioning strips 11 are protruding on the outer wall surface of the inner liner 12. Positioning grooves are provided on the inner wall surface of the thermos body 1 at the positions corresponding to the positioning strips 11, and the positioning strips 11 are all inserted into the positioning grooves. An annular groove is provided on the outer ring surface of the sealing part 9, and a sealing ring 10 is installed in the annular groove. The outer ring surface of the sealing ring 10 is in contact with the inner wall surface of the thermos body 1.

[0026] The inner wall of the annular groove is fitted with a rubber layer, which increases the sealing between the convex ring and the annular groove, while the sealing ring increases the sealing between the sealing part and the inner liner.

[0027] The antibacterial coating is a silver ion coating, which can increase the antibacterial effect of the inner liner and reduce bacterial growth.

[0028] In this embodiment, the positioning components all include limiting blocks 6 and torsion spring hinges. The heat insulation shell 2 is provided with multiple limiting grooves 5 at one end facing the base 3. The limiting blocks 6 are all installed on the base 3 through torsion spring hinges, and one end of the limiting blocks 6 is inserted into the limiting grooves 5.

[0029] In this embodiment, one end of the heat insulation shell 2 is bent inward at both ends and installed on the outer wall of the thermos cup body 1. One end of the heat insulation shell 2 protrudes to form a blocking part sleeved on the outside of the connecting ring 8, and a vacuum heat insulation cavity is formed between the heat insulation shell 2 and the thermos cup body 1.

[0030] In this embodiment, both the thermos body 1 and the inner liner 12 are made of stainless steel, which increases the safety of use.

[0031] The base has an external threaded connection with an adjustment ring. When increased stability is needed, the adjustment ring is rotated upwards so that the suction cup is positioned below it. Thus, when placed, the suction cup holds the thermos cup in place on a flat surface. When the suction effect is not needed, the adjustment ring is rotated downwards so that its bottom is below the bottom of the suction cup. In this case, the adjustment ring contacts the flat surface while the suction cup does not, preventing suction from affecting quick placement and removal.

[0032] The thermos cup has an inner liner inside, which is fixed in the thermos cup by a base. The base is locked to the heat insulation shell by a limiting block to prevent the base from rotating on its own and affecting the seal between the base and the thermos cup.

[0033] When the inner liner needs to be disassembled, push the limiting block outward to disengage it from the limiting groove. After the limiting block is removed, the base can rotate until it is removed from the thermos body. After the base is removed, the inner liner can be taken out along the positioning strip. Due to the openings at both ends of the inner liner, cleaning brushes can be inserted through the openings at both ends to thoroughly clean it. The inner liner can also be directly replaced to ensure cleanliness and antibacterial effect, increasing the safety of use.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
