Description

Technical Field

[0001] This utility model relates to a cup, specifically a convenient, leak-proof lid and a portable water cup. Background Technology

[0002] When drinking water at the office or while traveling, people generally carry and use cups. To facilitate drinking, there are cup lids with venting and water permeability. Cup lids generally consist of an upper lid and a lower lid. The upper lid usually has a pressing mechanism in the center, and the lower lid usually has a water-sealing component. The water-sealing component is generally connected to the shaft end of the pressing mechanism. When the pressing mechanism is pressed, it drives the water-sealing component, causing the water-sealing component to move, venting air or allowing water to flow out.

[0003] CN223111414U discloses a press-shaft water-sealing assembly, including a press-shaft and a water-sealing plate. The press-shaft includes a shaft cap and a shaft body. One end of the shaft body is the shaft cap. The shaft body is provided with a return spring setting part, a first water-sealing groove, a water-sealing plate sliding connection part, a second water-sealing groove, and a limiting component. The end of the shaft body with the shaft cap is the return spring setting part, on which a return spring is fitted. The other end of the shaft body is provided with a limiting component, a second water-sealing groove, and a water-sealing plate sliding connection part in sequence from the end upwards. The water-sealing plate sliding connection part is fitted with the water-sealing plate. A sliding gap is provided between the connecting hole of the water-sealing plate and the sliding connection part. The sliding gap allows the water-sealing plate to slide along the water-sealing plate sliding connection part under force. The limiting component is connected to or provided at the end of the shaft body and prevents the water-sealing plate from detaching from the shaft body. The first water-sealing groove and the second water-sealing groove are respectively provided with a sealing ring one and a sealing ring two.

[0004] The shaft is equipped with a first water-sealing groove and a second water-sealing groove, each fitted with a sealing ring (first and second). Sealing ring one engages with the pressing shaft cavity to seal water. Sealing ring two is positioned outside the water-sealing plate, sealing the gap between the water-sealing plate and the shaft after the water-sealing plate resets. The water-sealing plate engages with a water-sealing ring rib extending from one side of the lower cover. When the water-sealing plate is driven away from the water-sealing ring rib, water can flow out through the gap between the water-sealing plate and the water-sealing ring rib. By incorporating a sliding connection for the water-sealing plate, the water-sealing plate remains stationary when the pressing shaft is under force. The pressing mechanism has a small cross-section and experiences minimal pressure from the hot air inside the cup, allowing it to be easily pressed. As the pressing shaft moves, gas flows inside and outside the cup, achieving pressure balance. Continued pressing causes the pressing shaft to drive the water-sealing plate to continue moving, thus easily venting air and pouring water out during pressing.

[0005] The problem is that the pressing component requires manual pressing to open or close the sealing plate; in addition, due to the design of the pressing component, the pressing chamber has a large diameter, and the cross-sectional area of ​​the chamber for water flow when pouring water is relatively small, making it only suitable for pouring water out and not for convenient water filling. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a convenient water-filling, leak-proof lid and a portable water cup. The convenient water-filling, leak-proof lid and portable water cup can easily open or close the water seal without pressing; and it can also make it easier to add water into the cup.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical means: A convenient water-filling, leak-proof lid and portable water cup, including a cup lid and a snap-on lid, wherein the cup lid is provided with a shaft cavity or shaft hole for connecting a water-sealing shaft rod; The bottom end of the sealing shaft extending downwards out of the shaft cavity or shaft hole is not provided with a shaft limiting cap, which prevents the sealing shaft from slipping upwards from the shaft cavity or shaft hole; the upper end of the sealing shaft is connected to the sealing plate connecting part of the sealing plate. The spring is fitted onto the sealing shaft, with the top end of the spring abutting against the lower side of the sealing plate connection and the bottom end of the spring abutting against the bottom end of the shaft cavity or shaft hole of the cup lid, and the spring is in a compressed state. The cavity between the outer side of the shaft cavity and the inner wall of the cup lid, or the cavity between the upper side of the shaft hole and the inner wall of the cup lid, is a water flow cavity. A sealing ring is provided at the edge of the sealing part of the sealing plate, and the sealing part of the sealing plate closes or opens the water flow cavity. The cup lid has spaced water flow holes on the outer side of the shaft cavity or shaft hole. The cup lid is threadedly connected to the cup body; The buckle is threadedly connected to the cup lid or cup body.

[0008] The upper end of the sealing shaft is connected to the sealing plate connecting part of the sealing plate; any connection method with existing technology can be used, including but not limited to threaded connection, riveting, magnetic adsorption connection, shaft pin connection, etc.

[0009] The cup lid is connected to the cup body; it can be a threaded connection or a ferrule connection.

[0010] The sealing plate is connected to the sealing shaft, and a spring is sleeved on the sealing shaft. The spring is located between the sealing plate and the cup lid and is in a compressed state. When the sealing shaft is not subjected to external force from the lid, the spring causes the sealing plate to rise along the inner cavity of the cup lid, opening the water flow channel between the sealing plate and the inner wall or bottom of the cup lid. When the lid is connected to the cup lid or cup body by threads, the inner side of the top of the lid presses down on the sealing plate or the sealing shaft to close the water flow channel between the sealing plate and the inner wall or bottom of the cup lid.

[0011] When the lid is opened, the water flow channel between the sealing plate and the inner wall or bottom of the lid is opened; water can be added directly to the cup, poured out, or drunk directly. When the lid is screwed on, the inner side of the top of the lid presses down on the sealing plate or sealing shaft to close the water flow channel between the sealing plate and the inner wall or bottom of the lid, preventing water from flowing out of the cup. This effectively prevents the problem of water flowing out of the cup when it is placed flat in a bag if the sealing plate is not pressed to close it, which is a common issue with existing push-button switches.

[0012] As a further improvement to this technical solution: The top end of the sealing shaft is provided with a threaded connection part, which is connected to the sealing plate.

[0013] By providing a threaded connection, it is easy to connect to the sealing plate, and easy to install and disassemble the components.

[0014] As a further improvement to this technical solution: The cup lid is provided with a threaded connection part; at least a portion of the threaded connection part is used to connect to the cup body.

[0015] As a further improvement to this technical solution: The threaded connection part is provided with a first threaded connection part and a second threaded connection part. The first threaded connection part is used to connect the cup body, and the second threaded connection part is used to connect the buckle.

[0016] As a further improvement to this technical solution: The second threaded connection part is an external thread, and the cover is provided with an internal thread that mates with the second threaded connection part.

[0017] As a further improvement to this technical solution: The second threaded connection part is an internal thread, and the cover is provided with an external thread that mates with the second threaded connection part.

[0018] As a further improvement to this technical solution: The cup lid has a water-sealing rubber ring cavity at the cup mouth, and the water-sealing rubber ring is nested in the water-sealing rubber ring cavity.

[0019] By setting up a sealing ring cavity and sealing ring at the cup opening, the sealing performance of the cup lid connected to the cup body is improved.
