Detailed Implementation

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This embodiment provides a cup, which is a specific application of the innovative solution of this utility model on a cup. The innovative solution of this utility model can also be applied to liquid containers such as kettles. The cup includes a cup body and a push-button lid, wherein the cup body is not shown in the figure. Figure 1-7 As shown, the push-plate cover includes a cover body 100, a push plate 200, and a water sealing base 300. The cover body 100 has a drinking hole 110 and a mounting hole 120. The water sealing base 300 is provided with a sealing element 310. The push plate 200 is provided with a connecting post 210 that passes downward through the water sealing base 300. The lower end of the connecting post 210 is provided with a detachable limiting element 400. The limiting element 400 abuts against the bottom of the water sealing base 300 so that the sealing element 310 abuts against the cover body 100.

[0026] During installation, the limiting member 400 is fixed below the sealing base 300, creating a top-down tightening force that ensures a stable connection between the pusher 200 and the sealing base 300. Due to the abutting action of the limiting member 400, the seal 310 on the sealing base 300 is tightly pressed against the cover 100, ensuring that the drinking hole 110 is sealed when the pusher 200 is not in use, preventing liquid leakage. Compared to traditional snap-fit ​​fixing methods, this design allows for convenient disassembly of the pusher 200 and the sealing base 300 through the detachable limiting member 400. When cleaning or replacing parts is required, the user can easily remove the limiting member 400, separating the pusher 200 from the sealing base 300. Pushing the pusher 200 allows the sealing base 300 to move, enabling the seal 310 to switch between the closed and open positions of the drinking hole 110.

[0027] like Figure 1 , 5As shown in Figure 6, the connecting post 210 is provided with a limiting groove 211, and the limiting member 400 has a limiting cavity 410. A limiting rib 420 is embedded in the limiting groove 211 on the side wall of the limiting cavity 410. The limiting cavity 410 has a lateral opening, allowing the limiting member 400 to be laterally inserted into the connecting post 210. The limiting groove 211 serves as a fixing structure on the connecting post 210, guiding and constraining the position of the limiting member 400. The limiting rib 420 on the side wall of the limiting cavity 410 can be embedded in the limiting groove 211, forming a stable connection. The lateral opening of the limiting cavity 410 allows the limiting member 400 to be inserted into the connecting post 210 from the side, without the need for complex rotation or alignment operations. In other optional embodiments, the limiting member 400 can also be a nut that is threadedly engaged with the connecting post 210.

[0028] like Figure 3 , 4 As shown, an elastic element 320 is provided between the water-sealing base 300 and the limiting member 400, and the limiting member 400 abuts against the water-sealing base 300 through the elastic element 320. The water-sealing base 300 has a downward-facing groove, and the elastic element 320 is installed in the groove. The elastic element 320 can increase the friction between the limiting member 400 and the connecting column 210 bracket, thereby improving the stability of their connection. The elastic element 320 is made of silicone.

[0029] like Figure 5 , 6 As shown, the limiting member 400 has an abutment surface that contacts the elastic member 320, and the end of the abutment surface near the lateral opening has a guide surface 430. The guide surface 430 is designed as a slope or arc surface, and its function is to guide the limiting member 400 to gradually approach and compress the elastic member 320 during insertion. As the limiting member 400 is inserted deeper, the contact area between the guide surface 430 and the elastic member 320 gradually increases until the limiting rib 420 is completely embedded in the limiting groove 211, at which point the elastic member 320 reaches its maximum deformation, providing a stable abutment force.

[0030] like Figure 3 , 4As shown, the connecting post 210 is provided with a sealing ring 212, and the sealing seat 300 has a mounting through hole 330. The connecting post 210 passes through the mounting through hole 330, and the sealing ring 212 seals against the wall of the mounting through hole 330. The sealing ring 212, under pressure, generates elastic deformation to fill the gap between the connecting post 210 and the mounting through hole 330, thus achieving a sealing effect. The sealing ring 212 is typically made of elastic materials such as rubber, silicone, or polyurethane. These materials have good elasticity and corrosion resistance, and can maintain stable sealing performance under various environmental conditions. The main function of the sealing ring 212 is to prevent fluid leakage from the gap between the connecting post 210 and the mounting through hole 330. When the connecting post 210 passes through the mounting through hole 330, the sealing ring 212 is compressed and tightly adheres to the hole wall, forming an effective sealing barrier.

[0031] like Figure 4 , 7 As shown, the upper edge of the mounting through hole 330 protrudes upward to form a protruding post 340, which is movably embedded in the mounting hole 120. The protruding post 340, as part of the water-sealing seat 300, protrudes upward and embeds into the mounting hole 120 of another component. This design allows for a certain degree of freedom of movement while ensuring the stability of the connection. The inner wall of the mounting through hole 330 has a positioning groove 350, and the connecting post 210 has a positioning part 213 that cooperates with the positioning groove 350 to prevent the push plate 200 from rotating relative to the water-sealing seat 300, thus improving connection stability.

[0032] like Figure 4 As shown, the seal 310 is annular. When the drinking hole 110 is closed, the drinking hole 110 and the mounting hole 120 are located within the area enclosed by the seal 310. The main function of the seal 310 is to isolate the drinking hole 110 and the mounting hole 120, preventing fluid leakage from these two openings. When the drinking hole 110 is closed, the seal 310 fits tightly against the adjacent component, forming a closed sealing area to ensure that fluid does not leak out.

[0033] like Figure 6 As shown, the edge region of the pusher 200 is provided with a raised rib 220, and the pusher 200 abuts against the upper surface of the cover 100 through the raised rib 220. This reduces the contact area between the pusher 200 and the cover 100, thereby reducing frictional resistance.

[0034] like Figure 3 , 4As shown, the lid 100 comprises an inner liner 130 and an outer shell 140 that are fixed to each other. The lid 100 has a mounting groove 141, in which the pusher 200 is located. The separate design of the inner liner 130 and the outer shell 140 allows for the use of different materials. The inner liner 130 is preferably made of a high-temperature resistant, food-grade material, while the outer shell 140 is preferably made of a material with good decorative effect, thus maximizing their respective functions while reducing costs. The mounting groove 141 is designed to accommodate and fix the pusher 200, ensuring the correct position and stable movement of the pusher 200 on the lid 100. The inner liner 130 has threads for fixing to the cup body.
