In the embodiments of the present application, a straw-type water cup is provided, and for convenience of illustration and understanding, the following contents are provided on the basis of the structure of the illustrated product. Of course, it is understood by those skilled in the art that the above-described structure is only used as a specific example and illustrative illustration, and does not constitute a specific limitation to the technical solution provided by the present application.

As shown in fig. 1 to 4, a straw type water cup comprises a cup body 1 and a cup cover 2, wherein the cup cover 2 comprises an inner cover 21 which is hermetically mounted on the cup body 1 and an upper cover 22 which is detachably covered above the inner cover 21, the straw type water cup further comprises a suction nozzle 3 which is arranged on the inner cover 21, the suction nozzle 3 comprises a suction nozzle body 31 which is internally provided with a suction nozzle hole and a skirt 32 which extends outwards from the suction nozzle body 31, and the skirt 32 is integrally connected with a ventilation valve 33 which can communicate the inside and the outside of the cup body 1.

In the technical scheme of this application, inner cup 21 is used for sealed lid to close cup 1, and upper cover 22 is used for hiding the suction nozzle 3 of setting on inner cup 21, guarantees the cleaning of suction nozzle 3, and suction nozzle 3 is used for the user to suck liquid.

In this application, through be equipped with shirt rim 32 on suction nozzle 3, shirt rim 32 body coupling has the ventilative valve 33 that can communicate the inside and the outside of cup 1, namely suction nozzle 3 not only can be used for sucking liquid, the role of admitting air when having acted as the inside negative pressure that produces of cup 1, a multi-purpose has been realized, compare in current well suction nozzle and straw be two mutually independent structures, ventilative valve 33 and suction nozzle 3 body coupling, processing technology has been simplified, processing cost and accessory cost have been practiced thrift, and simultaneously, the quantity of the spare part of drinking cup has also been reduced, help simplifying the assembly step, improve assembly efficiency, in addition, installation on inner cup 21 is more firm when ventilative valve 33 and suction nozzle 3 body structure, it can not drop and lose not worry ventilative valve 33 when dismantling the washing. When the inside and the outside of the cup body 1 are communicated through the ventilation valve 33, in the sucking process, outside air can enter the inside of the cup body 1 to balance the air pressure inside and outside the cup body 1, so that negative pressure generated in the cup body 1 is avoided, and a user can continuously and smoothly suck liquid in the cup body. The skirt 32 extends outward from the nozzle body 31 to provide a design space for the breather valve 33, thereby preventing the breather valve 33 from interfering with the nozzle hole.

It should be noted that, the detachable manner of the upper cover 22 and the inner cover 21 is not particularly limited, for example, the upper cover 22 and the inner cover 21 may be screwed together by the cooperation of internal threads and external threads, screwed together by the cooperation of a screwing protrusion and a screwing clamping groove, clamped together by the cooperation of a buckle and a clamping groove, and interference insertion connected. As a preferred embodiment, as shown in fig. 1, a handle 4 can be rotatably connected to the outer side of the upper cover 22 for carrying. The inner cap 21 and the cup body 1 may be screwed together, and in order to seal the cup body 1 and the inner cap 21, a seal ring 5 may be provided between the cup body 1 and the inner cap 21, as shown in fig. 2 and 3.

In addition, the attachment position of the air vent valve 33 on the skirt 32 is not particularly limited, and the air vent valve 33 may be attached to the edge of the skirt 32 or the bottom of the skirt 32.
