When the nozzle cup is opened, no other parts interfere with the user's drinking water. When the nozzle cup is closed, liquid leakage can be avoided, thereby improving the user experience.

The specific implementation methods of the present application are further described below in combination with the accompanying drawings of the embodiments, so that the technical solution of the present application is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

This embodiment provides a push-type cup lid and a nozzle cup, as shown into, the nozzle cup includes a cup bodyand a cup lid. The cup lidincludes a lid body, a press button, a suction nozzleand a suction pipe. The press buttonis movably mounted on the lid body, the suction nozzleis fixed to the press button, the suction pipeis fixed to the lid body, and the suction pipeextends into the cup body, and the press buttonincludes a first position and a second position, so that when the press buttonis in the first position, a channel of the suction nozzlecommunicates with a channel of the suction pipe, and when the press buttonis in the second position, the channel of the suction nozzleis disconnected from the channel of the suction pipe.

As shown inand, the lid bodyhas a mounting chamberwith an opening facing upward, and the press buttonis embedded in the mounting chamber. One of an inner wall of the mounting chamberand a side wall of the press buttonhas a vertically extending guide bar, and another one of the inner wall of the mounting chamberand the side wall of the press buttonhas a guide groovecooperating with the guide bar. The press buttoncan move up and down in the mounting chamber. The shape of the cup lidis relatively regular, so as to prevent the press buttonfrom protruding from the lid body. In this embodiment, only the part of the suction nozzlethat protrudes upward from the press buttonprotrudes from the lid body. In other optional embodiments, the press buttoncan also be wrapped on the lid body, and the two can move up and down relatively by limiting the side wall of the lid body. At this time, the upper end of the lid bodyis embedded in the press button. In other optional embodiments, the guide barmay also be located on the side wall of the press button, and the guide groovemay be located on the inner wall of the mounting chamber.

As shown in, at this time, the press buttonis in the second position, and the nozzle cup is in a closed state. The lid bodyis provided with a mounting hole, and the suction nozzlepasses downward through the mounting hole. A first sealing elementis provided at a lower end of the suction nozzle. When the press buttonis in the second position, the first sealing elementabuts against a wall of the mounting hole. A water inletis provided at the side wall of the lower end of the suction nozzle. The water inletis positioned above the first sealing element. The water inletcommunicates with the channel of the suction nozzle. When the first sealing elementabuts against the hole wall of the mounting hole, the water inletis in the mounting holeand cannot be connected to the lower suction pipe, so that the nozzle cup is closed to prevent the nozzle cup from leaking.

As shown in, a return member is provided between the press buttonand the lid bodysuch that the press buttontends to move upward relative to the lid body. The return member enables the first sealing elementto be tightly against the hole wall of the mounting holeto improve the sealing effect. In one embodiment, the suction nozzleformed at a first end of the press button, and the return member includes a first springsleeved on the suction nozzleand a second springabutting against a second end of the press button. The two springs are respectively supported at the two ends of the press button, so that the force of the press buttonis more balanced, the tilting of the press buttonduring the movement is reduced, and the smoothness of the movement of the press buttonis ensured. The suction nozzleis integrally formed at the first end of the press button, which is simple to process and has a firm structure, so that the press buttonhas a greater tendency to be pressed by fingers.

When the press buttonis in the first position, that is, the press buttonmoves downward on the basis shown in, the channel of the suction pipecommunicates with the channel of the suction nozzlethrough the water inlet. The water inletis exposed to the mounting hole, and the suction pipeis connected to the channel of the suction nozzlethrough the water inlet, and the suction nozzle cup is opened. A second sealing elementis provided at the suction nozzle, and the second sealing elementabuts against the wall of the mounting hole. The second sealing elementhas a lip edgeembedded in the mounting hole, so that the air in the mounting chambercan be prevented from entering the suction nozzlethrough the matching gap between the suction nozzleand the hole wall of the mounting hole, thereby improving the smoothness of drinking.

The press buttonis provided with a spring buckle, and the lid bodyis provided with a clamping portion. When the press buttonis in the first position, the spring buckleengages with the clamping portion. The cooperation between the spring buckleand the clamping portioncan make the press buttonbe in the first position, and the user can also suck and drink by releasing the press buttonwith his fingers. In other optional embodiments, the spring bucklecan also be fixed on the lid body, and the clamping portionis integrally formed on the press button. In other optional embodiments, the spring bucklemay not be provided, and the nozzle cup is in an open state by pressing the press buttonwith the user's fingers.
