Description

Technical Field

[0001] This utility model relates to a cup lid, specifically a cup lid with a linked sealing structure for a water outlet and an air inlet. Background Technology

[0002] In existing water cups, for convenient drinking, many cup lids have a spout that connects to the inner cavity of the cup through a spout hole. Simultaneously, to ensure proper drinking, the lid also has a small air vent. When drinking through the spout, outside air enters the inner cavity of the cup through the air vent, balancing the internal and external air pressure and allowing the liquid to flow out evenly and continuously, thus enabling normal drinking.

[0003] Currently, the water outlet and air inlet on existing cup lids are independently designed. The air inlet has a small diameter and only allows air to enter; it remains open during use. The spout, connected to the water outlet, is typically fitted with a sealing plug. This plug is opened when drinking and closed when not in use. However, in practice, because the air inlet is always open, leakage can occur if the sealing plug fails, causing significant inconvenience. Utility Model Content

[0004] To address the aforementioned issues, this invention presents a linked sealing structure for the water outlet and air inlet in a cup lid. This structure seals the water outlet while simultaneously cutting off the air inlet, thereby effectively improving the sealing effect of the water outlet. Even if the sealing plug fails during use, leakage will not occur. This design features a simple and practical structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A linked sealing structure for a water outlet and an air inlet in a cup lid, comprising a cup lid, characterized in that: the cup lid is composed of a cup lid base and a top cover; the cup lid base is provided with a water outlet and an air inlet spaced apart; the top cover is provided with a water spout at the position corresponding to the water outlet and an operating groove at the position corresponding to the air inlet; a gap is left between the inlet of the water spout and the outlet of the water outlet to form a valve chamber, and a ball valve is fitted in the valve chamber, the ball valve being provided with a water guide hole; the upper surface of the cup lid base is aligned with... A control chamber is formed by recessing the air inlet hole. A rotating column is installed in the control chamber. The inner end of the rotating column is connected to the ball valve through a linkage to form a linkage structure. A notch is provided on one side wall of the rotating column. An operating wrench is provided on the top of the rotating column and extends out through the operating groove. Turning the operating wrench can drive the rotating column and the ball valve to rotate synchronously. The rotation of the rotating column can make the notch connect with or disconnect the air inlet hole. The rotation of the ball valve drives the water guide hole to rotate synchronously, so that the water outlet hole connects with or stops the water outlet.

[0007] More specifically, a lower connecting rubber plug is provided between the aforementioned water outlet and the ball valve.

[0008] More specifically, an upper connecting rubber plug is provided between the aforementioned water outlet inlet and the ball valve.

[0009] More specifically, the cup lid base has a connecting ring groove on its upper surface, and the upper cover has a connecting protrusion on its outer periphery facing downwards. Several engaging structures are provided between the outer side of the connecting protrusion and the connecting ring groove.

[0010] More specifically, the above-mentioned engaging structure includes a slot and a buckle, wherein the slot and the buckle are selectively disposed on the outer side of the connecting protrusion and the groove wall of the connecting ring groove.

[0011] More specifically, the outer periphery of the aforementioned cup lid base extends downward to form a connecting outer edge, on which a connecting external thread or connecting internal thread is provided for connection with the cup mouth of the cup body.

[0012] More specifically, the opening of the aforementioned air intake hole is equipped with an air intake nozzle.

[0013] The cup lid designed in this utility model features a ball valve and a rotating column with a linked action at the water outlet and air inlet. During use, operating a wrench causes the rotating column and ball valve to rotate synchronously, thereby simultaneously sealing the water outlet and spout while also closing the air inlet. This linked sealing structure effectively improves the sealing and leak-proof effect of the spout. Even if the ball valve fails to seal properly during use, the closed air inlet will prevent leakage, making it a simple and practical design. Attached Figure Description

Detailed Implementation

[0020] like Figure 1-4 As shown, a linkage sealing structure for a water outlet and an air inlet in a cup lid includes a cup lid, which is composed of a cup lid base 1 and an upper cover 2.

[0021] Here, in order to achieve the combined connection of the cup lid base 1 and the upper cover 2, the cup lid base 1 is provided with a connecting ring groove 11 on the outer periphery of its upper surface, while the upper cover 2 is provided with a connecting protrusion 21 on its outer periphery facing downward. Several engaging structures 3 are provided between the outer side of the connecting protrusion 21 and the connecting ring groove 11.

[0022] In this embodiment, the engaging structure 3 includes a slot 31 and a buckle 32. The buckle 32 is disposed on the outer surface of the connecting protruding ring 21, and the slot 31 is disposed on the groove wall of the connecting ring groove 11. The positions of the buckle 32 and the slot 31 can be interchanged. In practice, other engaging structures can also be used, as long as they can achieve the combined connection of the cup lid base 1 and the upper cover 2.

[0023] The cup lid base 1 is provided with a water outlet 12 and an air inlet 13 at intervals. The upper cover 2 is provided with a water spout 22 at the position corresponding to the water outlet 12, and the upper cover 2 is provided with an operating groove 23 with vertical hollowing at the position corresponding to the air inlet 13.

[0024] A gap is left between the inlet of the water outlet 22 and the outlet of the water outlet 12 to form a valve chamber 4. A ball valve 5 is installed in the valve chamber 4. The ball valve 5 is provided with a water guide hole 51. The water guide hole 51 can realize the connection or cut-off between the water outlet 22 and the water outlet 12 as the ball valve 5 rotates.

[0025] To ensure the sealing of the connection between the ball valve 5 and the outlet hole 12, a lower connecting plug 61 is provided between the outlet of the outlet hole 12 and the ball valve 5. The lower connecting plug is provided with a lower positioning protrusion ring 611 at the part corresponding to the outlet of the outlet hole 12, and the lower connecting plug 61 and the ball valve 5 are provided with a rounded concave mating sealing surface 612.

[0026] Similarly, to ensure the sealing of the connection between the ball valve 5 and the outlet 22, an upper connecting rubber plug 62 is provided between the inlet of the outlet 22 and the ball valve 5. The upper connecting rubber plug is provided with an upper positioning protrusion ring 621 at the part corresponding to the inlet of the outlet 22, and the upper connecting rubber plug 62 is also provided with a rounded concave mating sealing surface 622 at the end corresponding to the ball valve 5.

[0028] The cup lid base 1 has a connecting groove 14 between the control chamber 7 and the valve chamber 4. A linkage 9 is provided in the connecting groove 14, connecting the ball valve 5 and the rotating column 8 together to form a linkage structure. In this embodiment, the ball valve 5, linkage 9, and rotating column 8 are integrally formed. In practice, these three components can also adopt a separate assembly structure, where each component is processed independently before being assembled.

[0029] An operating wrench 82 is provided above the rotating column 8, extending outward through the operating groove 23. In use, operating the wrench 82 causes the rotating column 8 and the ball valve 5 to rotate synchronously. When the operating wrench 82 is turned towards one side of the control groove 23, the water outlet 12 and the water nozzle 22 are closed, and the air inlet hole 13 is sealed. When the operating wrench 82 is turned towards the other side of the control groove 23, the water outlet 12 and the water nozzle 22 are connected, and the air inlet hole 13 is opened.

[0030] The cup lid with the above structure has a ball valve 5 and a rotating column 8 with a linkage action on the water outlet 12 and the air inlet 13. In use, by turning the operating wrench 82, the rotating column 8 and the ball valve 5 are rotated synchronously, thereby achieving the simultaneous closure of the water outlet 12 and the water spout 22 and the air inlet 13. This linkage sealing structure can effectively improve the sealing and leak-proof effect of the water spout 22. Even if the ball valve 5 fails to seal properly during use, the air inlet 13 will keep the inner cavity of the cup airtight, thus preventing water leakage. It has the characteristics of simple structure and practicality.
