Description

Technical Field

[0001] This utility model relates to a cup, specifically a convenient lid for adding water and its 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 lid and its portable water cup. The convenient water-filling lid can easily open or close the water-sealing plate 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 lid includes a cup lid and a snap-on cover disposed above the cup lid and connected to the cup lid or cup body. The cup lid has a shaft cavity and a water flow cavity.

[0008] The lid opening faces downwards, and the cup lid and the clasp can be fastened together. The cup lid and the clasp can also be threaded together; or the clasp can be threaded together with the cup body.

[0009] The top end of the shaft cavity is provided with a limiting shaft hole, the diameter of which is smaller than the diameter of the shaft cavity. A water-sealing shaft rod and a spring are connected to the shaft cavity. A water-sealing plate is connected to the bottom end of the water-sealing shaft rod, and the spring is sleeved on the water-sealing shaft rod. The cavity between the outer side of the shaft cavity and the cup lid is a water flow cavity, and the connection between the water flow cavity and one side of the cup body is sealed or opened by a water sealing plate.

[0010] The top end of the sealing shaft extends out of the limiting shaft hole and connects to the first magnetic component. The diameter of the first magnetic component is larger than the diameter of the limiting shaft hole. The limiting shaft hole prevents the sealing shaft connected to the first magnetic component from sliding off the shaft cavity.

[0011] A second magnetic component is provided on the cover at a position corresponding to the first magnetic component, and a shaft movement interval is provided between the first magnetic component and the second magnetic component.

[0012] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: When the lid is upside down and connected to the cup lid, the second magnetic component attracts the first magnetic component, causing the first magnetic component to move upward and closer to the second magnetic component. This causes the first magnetic component to drive the sealing shaft upward. Simultaneously, the sealing shaft drives the sealing plate upward to close the connection between the water flow chamber and one side of the cup body. At the same time, the upward movement of the sealing shaft and sealing plate compresses the spring. After the spring is compressed, the connection between the sealing plate, the water flow chamber, and one side of the cup body is closed.

[0013] When the lid is removed from the cup lid, the first magnetic component loses its upward magnetic attraction, the spring returns to its original state, and the first magnetic component, the water-sealing shaft, and the water-sealing plate move downward under their own weight and the action of the spring. The water-sealing plate moves downward away from the connection between the water flow chamber and the cup body, opening the connection. At this time, water can be easily added into the cup body through the water flow chamber of the cup lid, or water can be poured out through the water flow chamber of the cup lid.

[0014] Therefore, this convenient water-adding lid allows the sealing plate to be easily opened or closed without pressing; and it also makes it easier to add water into the cup.

[0015] Further preferred technical solutions are as follows: One of the first magnetic component and the second magnetic component is a magnet, and the other is another material attracted by the magnet, or both the first magnetic component and the second magnetic component are magnets, and they are magnetically attracted to each other.

[0016] The bottom end of the sealing shaft is provided with a threaded connection part, and the sealing plate is connected to the sealing shaft by bolts and the threaded connection part.

[0017] The second magnetic component is disposed inside the cover, or the second magnetic component is disposed at the bottom of the inner side of the cover, or the top of the second magnetic component is snapped into the cover, with the bottom of the second magnetic component extending downward.

[0018] 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.

[0019] The threaded connection is an internal thread provided on the cup lid, and the threaded connection is connected to the cup body.

[0020] The threaded connection part is an external thread provided on the cup lid. The threaded connection part has a first threaded connection part and a second threaded connection part. The outer diameter of the first threaded connection part is larger than the outer diameter of the second threaded connection part. The first threaded connection part is used to connect to the cup body. The outer diameter of the second threaded connection part is smaller than the inner diameter of the cup body, so that the second threaded connection part extends downward into the cup body. The second threaded connection part connects to the filter cartridge.

[0021] 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.

[0022] The cup lid and the sealing plate are provided with a shaft end sealing plate cavity at the corresponding position; a sealing film or sealing ring is provided on the sealing plate to cooperate with the shaft end sealing plate cavity to achieve sealing; or a sealing ring is provided at the shaft end sealing plate cavity to cooperate with the sealing plate to achieve sealing; or a sealing film or sealing ring is provided on the sealing plate to cooperate with the sealing plate, and a sealing ring is also provided at the shaft end sealing plate cavity to achieve better sealing.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] See Figures 1-8 As can be seen, the present invention provides a convenient water-adding lid, which consists of a cup lid 2 and a snap-on cover 7 that is disposed above the cup lid 2 and connected to the cup lid 2 or the cup body 10.

[0035] The lid 7 has its opening facing downwards. The cup lid 2 and the lid 7 are fastened together, or the cup lid 2 and the lid 7 are threaded together, or the lid 7 and the cup body 10 are threaded together, or the lid 7 and the cup body 10 are fastened together.

[0036] The cup lid 2 is provided with a shaft cavity 201 and a water flow cavity 203.

[0037] The top end of the shaft cavity 201 is provided with a limiting shaft hole 202. The diameter of the limiting shaft hole 202 is smaller than the diameter of the shaft cavity 201. The shaft cavity 201 is connected to a water-sealing shaft 3 and a spring 4. The bottom end of the water-sealing shaft 3 is connected to a water-sealing plate 5. The spring 4 is sleeved on the water-sealing shaft 3.

[0038] The cavity between the outer side of the shaft cavity 201 and the cup lid 2 is a water flow cavity 203. The connection between the water flow cavity 203 and one side of the cup body 10 is sealed or opened by a water sealing piece 5.

[0039] The top end of the sealing shaft 3 extends out of the limiting shaft hole 202 and is connected to the first magnetic component 8. The diameter of the first magnetic component 8 is larger than the diameter of the limiting shaft hole 202. The limiting shaft hole 202 prevents the sealing shaft 3 connected to the first magnetic component 8 from sliding down from the shaft cavity 201.

[0040] The sealing shaft 3 and the first magnetic component 8 can also be configured as an integral structure. The spring 4 is placed in the shaft cavity 201. The bottom end of the sealing shaft 3 passes through the limiting shaft hole 202 and the spring 4 and extends out of the shaft cavity 201 before connecting to the sealing plate 5. The spring 4 extends out of the shaft cavity 201 from the bottom end of the sealing shaft 3 and then passes through the bottom end of the sealing shaft 3 before being placed into the shaft cavity 201. Then the bottom end of the sealing shaft 3 is connected to the sealing plate 5.

[0041] A second magnetic component 9 is provided on the cover 7 at a position corresponding to the first magnetic component 8, and a shaft movement interval is provided between the first magnetic component 8 and the second magnetic component 9.

[0042] One of the first magnetic component 8 and the second magnetic component 9 is a magnet, and the other is another material attracted by the magnet, or both the first magnetic component 8 and the second magnetic component 9 are magnets, and they are magnetically attracted to each other.

[0043] Figure 1 , Figure 4 As shown, the bottom end of the sealing shaft 3 is provided with a threaded connection part, and the bolt 6 and the threaded connection part connect the sealing plate 5 to the sealing shaft 3.

[0044] Figure 1 , Figure 5 As shown, the second magnetic component 9 is disposed inside the cover 7 or at the bottom of the inner side of the cover 7.

[0045] Alternatively, the top of the second magnetic component 9 can be snapped into the cover 7, and the bottom of the second magnetic component 9 can extend downwards.

[0046] Figure 1 , Figure 7 As shown, the cup lid 2 is provided with a threaded connection portion 206; at least a portion of the threaded connection portion 206 is used to connect the cup body 10.

[0047] Figure 6 As shown, the threaded connection 206 is an internal thread provided on the cup lid 2, and the threaded connection 206 is connected to the cup body 10.

[0048] Figure 7As shown, the threaded connection 206 is an external thread provided on the cup lid 2. The threaded connection 206 has a first threaded connection 2061 and a second threaded connection 2062. The outer diameter of the first threaded connection 2061 is larger than the outer diameter of the second threaded connection 2062. The first threaded connection 2061 is used to connect to the cup body 10. The outer diameter of the second threaded connection 2062 is smaller than the inner diameter of the cup body 10, so that the second threaded connection 2062 extends downward into the cup body 10. The second threaded connection 2062 is connected to the filter cartridge 207.

[0049] Figure 1 , Figure 2 As shown, the cup lid 2 is provided with a cup mouth sealing rubber ring cavity 204, and the cup mouth sealing rubber ring cavity 204 is nested with a sealing rubber ring 1.

[0050] The cup lid 2 is provided with a shaft end sealing plate cavity 205 corresponding to the water sealing plate 5; a sealing film or sealing ring is provided on the water sealing plate 5 to cooperate with the shaft end sealing plate cavity 205 to achieve sealing; or a sealing ring is provided at the shaft end sealing plate cavity 205 to cooperate with the water sealing plate 5 to achieve sealing; or while a sealing film or sealing ring is provided on the water sealing plate 5 to cooperate, a sealing ring is also provided at the shaft end sealing plate cavity 205 to achieve better sealing.

[0051] Figure 6 , Figure 8 As shown, a portable water cup includes the aforementioned cup lid 2.

[0052] The working principle of this embodiment is as follows: When the lid 7 is connected to the cup lid 2 with its opening facing downwards, the second magnetic component 9 attracts the first magnetic component 8, causing the first magnetic component 8 to move upwards and closer to the second magnetic component 9. This causes the first magnetic component 8 to drive the sealing shaft 3 to move upwards. Simultaneously, the sealing shaft 3 drives the sealing plate 5 to move upwards, closing the connection between the water flow cavity 203 and one side of the cup body 10. At the same time, the upward movement of the sealing shaft 3 and the sealing plate 5 compresses the spring 4. After the spring 4 is compressed, the connection between the sealing plate 5, the water flow cavity 203, and one side of the cup body 10 is closed. The lid 2 and the lid 7 can be connected by a snap-fit ​​connection or a threaded connection; or the lid 7 can be threaded to the cup body 10 or snap-fitted to the cup body 10, all of which allow the lid 7 to be connected to the cup lid 2 with its opening facing downwards.

[0053] When the lid 7 is removed from the cup lid 2, the first magnetic component 8 loses its upward magnetic attraction, the spring 4 returns to its original state, and the first magnetic component 8, the water-sealing shaft 3, and the water-sealing plate 5 move downward under their own weight and the action of the spring 4. The water-sealing plate 5 moves downward away from the connection between the water flow cavity 203 and the cup body 10, thus opening the connection. At this time, water can be easily added into the cup body 10 through the water flow cavity 203 of the cup lid 2, or water can be poured out through the water flow cavity 203 of the cup lid 2.

[0054] Therefore, this convenient water-adding lid allows the sealing plate 5 to be opened or closed easily without pressing; and it also makes it easier to add water into the cup body 10.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent structural changes made based on the content of the present utility model specification and drawings are included within the scope of the present utility model.
