[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] Please refer to Figure 1-2 The present embodiment provides a thermos cup, comprising a cup body 1, a cup cover 2 and an opening and closing cover 3, wherein the cup body 1 is provided with an inner cavity, and the cup cover 2 is provided at the opening of the inner cavity;

[0025] The cup cover 2 is provided with a suction nozzle 4 and an air leakage hole 22. The suction nozzle 4 is connected to the inner cavity of the cup body 1. The suction nozzle 4 is elastic and can move between a folded position and an unfolded position. One end of the air leakage hole 22 is connected to the inner cavity of the cup body 1, and the other end of the air leakage hole 22 is connected to the outside.

[0026] The opening and closing cover 3 is installed on the cup cover 2 and can move between an open position and a closed position. When the opening and closing cover 3 is in the closed position, the suction nozzle 4 moves to the folded position and is clamped between the opening and closing cover 3 and the cup cover 2 and covers the other end of the air leakage hole 22; when the opening and closing cover 3 is in the open position, the suction nozzle 4 rebounds to the unfolded position and moves away from the other end of the air leakage hole 22 so that the other end of the air leakage hole 22 is connected to the outside.

[0027] In this embodiment, the cup cover 2 is provided with a water hole 21 and a suction nozzle 4. The water hole 21 passes through the cup cover 2. The suction nozzle 4 is fixedly connected to the cup cover 2 and communicates with the water hole 21, so that the water in the cup body 1 can flow to the suction nozzle 4 through the water hole 21 and flow out of the cup from the suction nozzle 4. The cup cover 2 is also provided with an opening and closing cover 3. There is a certain space between the opening and closing cover 3 and the cup cover 2. The suction nozzle 4 is arranged in the space between the opening and closing cover 3 and the cup cover 2. Please refer to Figure 4 When the opening and closing cover 3 is in the open position, the suction nozzle 4 extends out from the opening of the opening and closing cover 3.

[0028] Please refer to Figure 3 When the opening and closing cover 3 is in the closed position, the suction nozzle 4 is squeezed by the opening and closing cover 3 and bent downward. The suction nozzle 4 is sandwiched between the opening and closing cover 3 and the cup cover 2 and covers the air leakage hole 22. The downward bent suction nozzle 4 is squeezed by the opening and closing cover 3 to seal the air leakage hole 22 to prevent water in the cup from flowing out of the air leakage hole 22. At the same time, it can reduce the air flow inside and outside the water cup to improve the insulation effect of the thermos cup.

[0029] When the opening and closing cover 3 needs to be closed, the opening and closing cover 3 will first push the suction nozzle 4, causing the suction nozzle 4 to deform and bend downward in a "V" shape. The suction nozzle 4 will continue to deform as the opening and closing cover 3 continues to move toward the closed position until the suction nozzle 4 contacts the air leakage hole 22 and seals the air leakage hole 22.

[0030] When the opening and closing cover 3 needs to be opened to drink water, the downwardly bent suction nozzle 4 will gradually rebound upward and extend out of the opening and closing cover 3 as the pressure of the opening and closing cover 3 is gradually lost. At the same time, the suction nozzle 4 will no longer seal the air leakage hole 22. After the air leakage hole 22 is opened, the pressure in the cup will be released to prevent the suction nozzle 4 from spraying water due to the pressure problem in the cup.

[0031] Please refer to Figure 3-4 In a further embodiment of the present invention, a crease groove 41 is left on the side of the suction nozzle 4 close to the air leakage hole 22 , and the suction nozzle 4 can be folded along the crease groove 41 .

[0032] In this embodiment, a crease groove 41 is left on the side of the suction nozzle 4 close to the air leakage hole 22, which can ensure that the suction nozzle 4 is bent at the same place each time, thereby avoiding the suction nozzle 4 being insufficient in length after bending and unable to cover the air leakage hole 22 due to different bending positions, further affecting the sealing of the air leakage hole 22.

[0033] Please refer to Figure 3-4 In a further embodiment of the present invention, a barrier sheet 42 is provided inside the suction nozzle 4 . Furthermore, a barrier sheet 42 is provided on the inner wall corresponding to the crease groove of the suction nozzle 4 .

[0034] One end of the nozzle 4 connected to the outside is the water outlet. One end of the barrier sheet 42 is fixedly connected to the inner wall of the nozzle 4. The other end of the barrier sheet 42 has a gap with the inner wall of the nozzle 4 and extends in the opposite direction of the water outlet.

[0035] In the present embodiment, a barrier sheet 42 is correspondingly provided inside the bending part of the suction nozzle 4. When the suction nozzle 4 is bent, the barrier sheet 42 will contact with the upper wall inside the suction nozzle 4 and form a closure, completely blocking the inside of the suction nozzle 4 and thus enhancing the anti-water spraying effect of the suction nozzle 4. At the same time, when the suction nozzle 4 rebounds after the opening and closing cover 3 is opened, the time required to extend the suction nozzle 4 can also be opened, so that the air release hole 22 has sufficient time to release the pressure in the cup.

[0036] In a further embodiment of the utility model, a straw 6 is further provided on the cup cover 2 , one end of the straw 6 is connected to and communicates with the suction nozzle 4 , and the other end of the straw 6 penetrates into the bottom of the inner cavity of the cup body 1 .

[0037] In this embodiment, a straw 6 is provided on the cup cover 2, which effectively improves the convenience of using the thermos cup and makes it easier for the user of the thermos cup to use the thermos cup.

[0038] In a further embodiment of the present invention, the straw 6 is detachably connected to the suction nozzle 4 via a connecting block 61 , and the connecting block 61 is fixedly connected to the outer surface of one end of the straw 6 .

[0039] In this embodiment, the straw 6 and the nozzle 4 are detachably connected, and the user can clean and disinfect them regularly to maintain hygiene.

[0040] In a further embodiment of the present invention, a clamping block 43 is provided on the inner wall of the suction nozzle 4 at the connection with the connecting block 61, and a clamping groove 62 matching the shape of the clamping block 43 is provided on the outside of the connecting block 61. In a further embodiment of the present invention, the cup body 1 is a double-layer sandwich structure with a vacuum layer in the middle. The double-layer sandwich structure allows the cup body 1 to have good heat preservation performance. The cup cover 2 is detachably connected to the cup body 1 through a thread, and a handle 5 is also provided on the top of the opening and closing cover 3.

[0041] In a further embodiment of the present invention, the opening and closing cover 3 is a sliding cover, and the opening and closing cover 3 is axially connected to the top of the cup cover 2 and can move between an open position and a closed position. Figure 1 At A, the opening and closing cover 3 is axially connected above the cup cover 2 and performs a circular motion between an open position and a closed position.

[0042] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
