In this structure, there is no need to set a separate air leakage hole, the structure is simple, and it is convenient for production and processing. In this structure, the sealing cover 4 drives the sealing convex edge 35 on the straw 3 to seal the air leakage channel 23, so that the air leakage channel 23 is sealed while the straw 3 is sealed, so as to avoid accidental spillage of beverages during the movement and transportation of the water cup, and to avoid dust from entering the air leakage channel 23, which is convenient for users to use. In addition, in this structure, when the sealing cover 4 is disassembled, the sealing convex edge 35 will be reset first, so that the air leakage channel 23 connects the inside and outside of the water cup, so as to balance the air pressure inside and outside the water cup in advance, avoid the beverage from spraying out of the straw 3, and facilitate the separation of the sealing cover 4 from the straw 3.

[0038] The cup cover 2 and the sealing cover 4 can be connected by a snap-fit ​​structure, and the cup cover 2 and the sealing cover 4 can also be connected by a threaded structure. In this embodiment, the cup cover 2 is provided with a first threaded portion 24, and the sealing cover 4 is provided with a second threaded portion 45 adapted to the first threaded portion 24; the first threaded portion 24 and the second threaded portion 45 are controlled to cooperate, so that the sealing cover 4 drives the sealing ridge 35 to seal the air leakage channel 23. The setting of the first threaded portion 24 and the second threaded portion 45 facilitates the tight sealing of the air leakage channel 23 by the sealing ridge 35, avoiding the wear of the cup cover 2 and the sealing cover 4 after long-term use, affecting the sealing of the air leakage channel 23 by the sealing ridge 35. In the utility model, a flexible connecting rope 5 is provided between the sealing cover 4 and the cup cover 2. The setting of the flexible connecting rope 5 avoids the accidental falling or loss of the sealing cover 4, which is convenient for users to use.

[0039] In this embodiment, the upper end of the cup cover 2 extends to form a protrusion 21, the mounting hole 22 is arranged in the protrusion 21, and the first threaded portion 24 is arranged on the outer periphery of the protrusion 21, and the two ends of the flexible connecting rope 5 are respectively provided with connecting rings 51, and the connecting rings 51 are respectively connected to the protrusion 21 and the sealing cover 4.

The supporting protrusion 341 can abut against the cup cover 2 to form a gap between the supporting protrusion 341 and the cup cover 2, and prevent the supporting protrusion 341 from sealing the mounting hole 22. The annular limiting ridge 34 is conducive to the stable installation of the straw 3, and can reduce the beverage from entering the air leakage channel 23. The setting of the supporting protrusion 341 prevents the supporting protrusion 341 from sealing the air leakage channel 23, so that the sealing cover 4 can control the connection or sealing of the air leakage channel 23, which is convenient for the user to use.

[0044] The sealing cover 4 is provided with a sealing groove 41, the suction nozzle 33 is inserted into the sealing groove 41, and a sealing plug 42 is provided at the bottom of the sealing groove 41, the sealing plug 42 penetrates into the suction nozzle 33 and seals the suction nozzle 33. The provision of the sealing plug 42 is beneficial to improving the sealing effect of the suction nozzle 33, and preventing the drink from spraying out of the suction nozzle 33 when the sealing cover 4 is opened.

[0045] Preferably, an inclined guide surface 43 is provided at the end of the sealing plug 42, and the sealing plug 42 is guided into the suction nozzle part 33 by the guide surface 43. The setting of the guide surface 43 facilitates the sealing plug 42 to penetrate into the suction nozzle part 33 and facilitates the sealing cover 4 to seal the suction nozzle part 33.

[0046] The sealing ridge 35 and the mounting groove 44 can be loosely matched, and the straw hole 36 is sealed only by the sealing plug 42 during use. This structure facilitates the separation of the sealing cover 4 from the suction nozzle portion 33. In this embodiment, the sealing cover 4 is preferably provided with a mounting groove 44 adapted to the sealing ridge 35. The sealing ridge 35 and the mounting groove 44 are tightly matched, so that the sealing cover 4 can drive the sealing ridge 35 away from the mounting hole 22. The tightly matched sealing ridge 35 and the mounting groove 44 facilitate the sealing cover 4 to drive the sealing ridge 35 away from the mounting hole 22, so that the air leakage channel 23 can quickly balance the air pressure inside and outside the water cup. In this structure, the sealing ridge 35 can seal the sealing cover 4 to prevent the drink from spraying out of the suction nozzle portion 33.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
