[0027] like Figure 1-7As shown, a flip-top water cup includes a cup body 1, one end of the cup body 1 has a cup mouth, a sealing seat 2 is installed at the cup mouth of the cup body 1, a drinking structure 8 is provided on the sealing seat 2, an opening and closing assembly is movably mounted on the outer periphery of the sealing seat 2, a middle frame 3 is fixedly mounted on the outer periphery of the sealing seat 2, the opening and closing assembly is located between the middle frame 3 and the sealing seat 2, a dust cover 4 is hingedly mounted on one side of the middle frame 3 through a rotating shaft 16, a control valve 5 is arranged in the sealing seat 2, the control valve 5 is V-shaped, a key port 17 is arranged on one side of the rotating shaft 16 on the middle frame 3, a key 6 is arranged in the key port 17, the key 6 is connected with the opening and closing assembly, the dust cover 4 and the opening and closing assembly form a buckle structure, pressing the key 6 drives the opening and closing assembly to push against the control valve to open the control valve, and the dust cover 4 is unlocked. The control valve will be converted from a closed state to an open state after being subjected to an external pushing force. When the cup body is filled with hot water, the pressure in the cup body will be higher than the external pressure. If the air pressure is not reduced first, it is easy to cause water to spray out directly when drinking water. After pressing the button, the opening and closing member will press against the control valve to open the control valve, so that the steam in the cup body is discharged as the lid is opened. A torsion spring 22 is provided on the rotating shaft 16 to achieve automatic recovery.

[0028] The opening and closing assembly includes an opening and closing frame 7, a buckle frame 9 is provided on one side of the opening and closing frame 7, a connecting member 10 is provided on the other side of the opening and closing frame 7, and the connecting member 10 is connected to the button 6. A pressing protrusion 11 for pressing against the control valve 5 is provided in the opening and closing frame 7, a lower buckle 12 and an upper buckle 13 are provided in the buckle frame 9, and the upper buckle 13 is located above the lower buckle 12. The lower buckle 12 and the upper buckle 13 are symmetrically arranged on both sides of the buckle frame 9, and the lower buckle 12 is on the side away from the pressing protrusion 11, and the upper buckle 13 is on the side close to the pressing protrusion 13. A buckle sheet 14 is provided in the dust cover 4, and a buckle hole 15 is provided on the buckle sheet 14. The lower buckle 12 and the upper buckle 13 are matched and plugged with the buckle hole 15 of the dust cover 4. The buckle frame 9 is located on the other side of the symmetrical rotation axis of the middle frame 3, and the connecting member is located on one side of the rotation axis of the middle frame. Press the button from the side where the dust cover is hingedly installed with the middle frame. The opening and closing frame, the buckle frame, the connecting piece, the top pressing protrusion, the upper buckle and the lower buckle are an integrated structure. The top pressing protrusion protrudes horizontally. The button is provided with a pressing hole, and the connecting piece is provided with a barb, and the barb is inserted into the pressing hole. A reset spring can be arranged between the opening and closing frame and the middle frame. After pressing the button, the opening and closing frame is pushed and the reset spring is compressed. After releasing the button, the opening and closing frame is automatically reset by the restoring force of the reset spring. A handle 23 can be arranged on the middle frame 3.

[0029] In the initial state, the lower buckle 12 extends into the buckle hole 15 of the buckle piece 14 of the dust cover 4, and the upper buckle 13 is located on the side of the buckle piece 14 and does not contact the buckle piece 14. After applying pressure to the button 6 from the outside, the button 6 moves downward toward the inside of the middle frame 3, and pushes the opening and closing frame 7 to move toward the buckle frame 9 through the connecting piece 10. The pressing protrusion 11 pushes the control valve 5, and the control valve 5 is pushed in the length direction, which is equivalent to the control valve 5 being squeezed and contracted, so it becomes larger in the width direction accordingly, so that the bottom of the V-shaped control valve 5 is converted from a closed state to an open state. At the same time, the opening and closing frame 7 moves as a whole, so that the lower buckle 12 is disengaged from the buckle hole 15 of the buckle piece 14, and the buckle piece 14 is not restricted by the lower buckle 12, so that the dust cover 4 pops up for the first time. In this process, the button 6 continues to be subjected to pressing pressure, that is, the opening and closing frame 7 continues to move, and the upper buckle 13 also moves. The horizontal position of the buckle piece 14 is relatively unchanged, and the buckle piece 14 only moves up and down. The lower buckle 12 is disengaged from the buckle hole 15 of the buckle piece 14, and then with the upward movement of the buckle piece 14 and the movement of the upper buckle 13, the upper buckle 13 is inserted into the buckle hole 15 of the buckle piece 14, and the dust cover 4 is restricted. At the same time, since the control valve is opened, the air pressure in the cup body is released, that is, there is a time difference of two times in the opening process of the dust cover, and there are two opening stages, that is, the dust cover forms a secondary pop-up function.

[0030] In addition, when the control valve 5 is not subjected to external thrust, a negative pressure is formed inside the cup body 1 when absorbing water, and the external air pressure will enter from the control valve to open the control valve, thereby forming an air return function, maintaining the air pressure balance inside and outside the cup body, and ensuring normal water absorption behavior.

[0031] The middle frame 3 is provided with a through hole 18 , and the buckle piece 14 of the dust cover 4 movably passes through the through hole 18 and enters the buckle frame 9 .

[0032] The middle frame 3 is provided with a limiting hole 19 , and the outer side wall of the sealing seat 2 is provided with a limiting column 20 , which is inserted into the limiting hole 19 to facilitate the stable assembly of the middle frame.

[0033] The sealing seat 2 includes a seat body 21 and a seat surface 22, the seat surface 22 is arranged on the seat body 21, the seat body 21 is installed at the cup mouth of the cup body 1, the control valve 5 is integrally formed on the seat surface 22, the upper part of the control valve 5 is exposed on the seat surface 22, and the lower part of the control valve 5 is located in the seat surface 22. The seat body 21 and the cup body 1 are threadedly installed, and the middle frame is clamped and installed with the seat body.

[0034] The drinking water structure 8 is a suction nozzle formed on the seat surface, and a suction straw 24 is provided in the cup body, and the suction straw is connected to the suction nozzle.

[0035] When the dust cover is closed, the nozzle is covered inside. The snap-fit ​​piece of the dust cover passes through the through hole of the middle frame and enters into the snap-fit ​​frame. The button is set on one side of the shaft on the middle frame. When the button is pressed, the button pushes the connecting piece inward, and the connecting piece drives the opening and closing frame to move toward the side of the snap-fit ​​piece of the dust cover. The top pressure protrusion presses against the control valve, so that the control valve is converted from a closed state to an open state, and the pressure in the cup body is released. The snap-fit ​​piece is snapped together twice by the front and back of the lower snap and the upper snap, so that a time difference is formed from closing to opening of the dust cover, forming a secondary opening, and the pressure in the cup body is released when it is not fully opened, to ensure that no hot steam will rush out after the dust cover is fully opened.

[0036] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
