When the plug body 4 moves downward along the axis of the thermos cup with the inner cover 3, the lower end of the plug body 4 extends into the neck of the cup mouth to block the neck, and the water outlet channel 21 is closed. This solution has fewer parts, is easy to assemble, and saves costs. The inner cover 3 has a vacuum inner cavity, which further improves the insulation effect of the thermos cup.

[0041] Specifically, the inner cover 3 is provided with a blocking portion 31, such as Figure 4As shown, the barrier portion 31 is used to open or close the water outlet 22. When the inner cover 3 is covered with the outer cover 2, the barrier portion 31 blocks the water outlet 22, and the water outlet 22 is closed to prevent particles outside the cup body 1 from falling on the water outlet 22 and the water outlet channel 21, and water and other liquids are contaminated when poured out; when the inner cover 3 drives the plug body 4 to move upward and the plug body 4 is opened, a gap is formed between the barrier portion 31 and the water outlet 22. At this time, the water outlet 22 is opened, and the water and other liquids in the cup body 1 are poured out through the water outlet channel 21 and the water outlet 22 in turn; the water outlet 22 is arranged on the outer cover 2 in a surrounding manner, and the barrier portion 31 is an annular sheet.

[0043] Specifically, Figure 4 As shown, the plug body 4 is provided with a sealing ring 41. When the plug body 4 opens and moves upward, the sealing ring 41 is pressed on the inner ring 23. The setting of the sealing ring 41 can prevent the water and other liquids from overflowing from the threaded connection between the inner cover 3 and the outer cover 2 when pouring water or other liquids, causing scattering when pouring water or other liquids, affecting the user experience. The plug body 4 is also fixed with a sealing ring 42 on the outer edge. The sealing ring 42 is provided with an elastic sheet 43. When the plug body 4 is in a closed state, the elastic sheet 43 on the sealing ring 42 is squeezed and fits with the neck of the cup mouth to block the neck of the cup mouth; when the plug body 4 is in an open state, the elastic sheet 43 on the sealing ring 42 breaks the plug body 4 and moves upward, the elastic sheet 43 and the sealing ring are away from the neck of the cup mouth, the neck is opened, the elastic sheet 43 returns to the initial state, and the water outlet channel 21 is opened.

[0044] Specifically, there are two ways to connect the plug body 4 and the inner cover 3. First, the inner cover 3 is sleeved on the plug body 4. Specifically, an annular convex portion 32 is provided on the outer wall of the plug body 4, and an annular concave portion 44 matching the convex portion 32 is provided on the inner wall of the inner cover 3, or an annular concave portion 44 is provided on the outer wall of the plug body 4, and an annular convex portion 32 matching the concave portion 44 is provided on the inner wall of the inner cover 3, and the plug body 4 and the inner cover 3 are sleeved through the concave portion 44; second, the inner cover 3 and the plug body 4 are an integral structure, and preferably the inner cover 3 is sleeved on the plug body 4. The advantage is that the inner cover 3 can rotate relative to the plug body 4, and the relative up and down movement of the inner cover 3 and the plug body 4 is limited, which can prevent the plug body 4 from rotating with the inner cover 3 when the inner cover 3 rotates, resulting in the sealing ring and the elastic sheet 43 on the plug body 4 rotating relative to the inner wall of the cup body 1 and causing wear, thereby reducing the thermal insulation effect of the cup body 1.

[0045] Specifically, in order to improve the insulation effect of the thermos cup, the plug body 4 has a vacuum inner cavity, the plug body 4 is made of food-grade stainless steel, or the plug body 4 is a food-grade plastic body with built-in foam, or the plug body 4 is made of food-grade foam material.

[0046] Specifically, the outer cover 2 is threadedly connected to the cup body 1, and a sealing ring 3 25 is provided at the connection between the outer cover 2 and the cup body 1. The sealing ring 3 25 is provided at the position where the outer cover 2 and the cup body 1 are squeezed. When the outer cover 2 and the cup body 1 are closed, the upper end of the cup mouth is pressed against the bottom surface of the sealing ring, and the bottom surface of the outer cover 2 presses the top surface of the sealing ring. The sealing ring 3 25 provides a tighter bite force for the threaded connection to prevent the outer cover 2 from rotating when the inner cover 3 rotates; or the threaded rotation direction of the outer cover 2 and the cup body 1 is different from the threaded rotation direction of the outer cover 2 and the inner cover 3, and when the inner cover 3 rotates, the outer cover 2 rotates.

[0047] like Figure 3 As shown, the outer cover 2 or the inner cover 3 is provided with a detachable cover 5, which can cover the water outlet 22 to prevent dust from entering the cover. At the same time, the cover 5 can be removed and used as an outer cup when going on a long journey.
