Description

Technical Field

[0001] This utility model relates to the field of cup lids, and in particular, to a drinking cup lid structure. Background Technology

[0002] Currently, Chinese patent CN218683547U discloses a straw cup lid and a straw cup. The straw cup lid includes an end cap, a body, and a straw seat made of elastic material, which are sequentially fitted from top to bottom. The straw seat is provided with a straw and an exhaust vent that connect the upper and lower surfaces. A one-way valve is provided inside the exhaust vent and the straw. A button is provided on the side wall of the end cap. Pressing the button squeezes the straw seat inward, and the exhaust vent deforms under pressure to open the one-way valve.

[0003] Not only does it prevent liquid leakage when not in use, but users can also open the one-way valve to allow air to enter or exit the cup by pressing the button, allowing for safe and quick drinking from the straw. The locking button prevents accidental button operation during use, ensuring safe and reliable use.

[0004] The straw is positioned in the center or near the center of the lid. While this layout enables basic drinking with a straw, it has shortcomings in practical use: when using a centrally located straw, especially when there is little liquid left in the cup, the user often needs to tilt the cup significantly or tilt their head back at a considerable angle to drink the liquid smoothly. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a drinking cup lid structure to facilitate drinking liquids.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a drinking cup lid structure, including a lid body and a straw, wherein the straw is hinged to the lid body by a protruding post, and the lid body is provided with an outlet hole and a vent hole, wherein the outlet hole and the vent hole are connected to the upper surface and the lower surface of the lid body, and the straw is rotated along the axis of the protruding post so that the outlet hole is connected to the straw and the straw is close to the edge of the lid body.

[0007] To achieve the above technical solution, the straw is rotated along the axis of the protruding post, and the straw is close to the edge of the lid. At the same time, the straw is connected to the outlet hole, so that when there is not much liquid left in the cup, the cup does not need to be tilted significantly, or the user does not need to tilt their head back at a large angle to drink the liquid smoothly.

[0008] As a preferred embodiment of this utility model, the cover is provided with a placement groove, the outlet hole and the air guide hole are located in the placement groove, and a plunger for sealing the air guide hole is fixedly connected to the outer wall of the straw.

[0009] The above technical solution makes the structure more compact and can effectively reduce the thickness of the cover; when the straw is stored in the placement slot, the plunger covers the air vent, which can also play a certain role in preventing dust or pollution.

[0010] As a preferred embodiment of this utility model, the inner wall of the placement groove is provided with a guide groove and a rotating recess, the protrusion is fixed on the outer wall of the straw and rotatably connected in the rotating recess, the guide groove is connected to the rotating recess, and the width of the guide groove gradually decreases from the end away from the rotating recess towards the rotating recess.

[0011] To achieve the above technical solution, during assembly, the protrusion on the straw can be aligned with the wider end of the guide groove, and then slid along the guide groove. The gradually narrowing groove wall will naturally guide the protrusion and "squeeze" it into the precise position of the rotating concave hole. Compared with a simple round hole that requires precise alignment for insertion, this design reduces assembly difficulty and alignment time, making it particularly suitable for automated or rapid manual assembly, thereby improving production efficiency and reducing manufacturing costs.

[0012] As a preferred embodiment of this utility model, the cover is provided with an outlet groove and a constant pressure hole, and the outlet groove and the constant pressure hole are both connected to the upper surface and the lower surface of the cover.

[0013] The above technical solution enables liquid to flow out from the outlet tank, thereby further improving its practicality.

[0014] As a preferred embodiment of this utility model, the cover body is provided with a U-shaped groove, the outlet groove and the constant pressure hole are both located in the U-shaped groove, a cover plate is hinged in the U-shaped groove, and a sealing plug for sealing the outlet groove and a protrusion for sealing the constant pressure hole are connected to the cover plate.

[0015] By implementing the above technical solution, closing the lid simultaneously and automatically seals both openings. This significantly improves the lid's leak-proof performance, effectively preventing accidental spills. At the same time, this design makes the opening and closing operation very simple and convenient, the structure is relatively compact, and it protects the openings from contamination when closed.

[0016] As a preferred embodiment of this utility model, a connecting hole is provided on the U-shaped groove, the connecting hole is connected to the placement groove, and a connecting shaft is fixed on the cover plate, the connecting shaft being rotatably connected to the connecting hole.

[0017] The above technical solution facilitates cleaning of the connection holes and makes the structure more compact.

[0018] As a preferred embodiment of this utility model, the edge of the cover is provided with a connecting groove communicating with the U-shaped groove, the cover plate is connected with a protrusion, a limiting plate is connected to the protrusion, a slot is formed between the limiting plate and the cover plate, and the slot corresponds to the connecting groove.

[0019] The above technical solution achieves a secure lock on the cover by a precise fit between the connecting groove of the cover body and the locking groove of the cover plate. This effectively prevents the cover from accidentally popping open and causing leakage during carrying or shaking, and ensures the continued effectiveness of the internal seal. The connecting groove also guides the flow of liquid. The raised design facilitates finger opening, balancing safety and convenience.

[0020] As a preferred embodiment of this utility model, a positioning groove is provided on the cover plate, a positioning ring is connected to the inner wall of the positioning groove, an annular groove is provided on the outer wall of the sealing plug, and the positioning ring is embedded in the annular groove.

[0021] The above technical solution makes it easier to fix the sealing plug in the positioning groove.

[0022] As a preferred embodiment of this utility model, a sealing ring is fixedly connected to the outer wall of the sealing plug, the cover plate is flipped along the hinge to make the sealing plug embedded in the outlet groove, and the sealing ring abuts against the inner wall of the U-shaped groove, and the upper surface of the cover plate is flush with the upper surface of the cover body.

[0023] To achieve the above technical solution, the upper surface of the lid is flush with the upper surface of the lid body when closed, resulting in a smooth, streamlined, and more integrated appearance for the entire lid. This not only enhances aesthetics but also reduces the possibility of snagging and facilitates surface cleaning. By adding a sealing ring to the outer wall of the sealing plug, a double seal is formed over the outlet groove. When the lid is closed, the sealing plug blocks the outlet groove, while the sealing ring is pressed tightly against the inner wall of the U-shaped groove, providing a second barrier that significantly improves the reliability of the seal and more effectively prevents liquid leakage.
