Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to a double drinking cup stopper. Background Technology

[0002] Water cups are common items in daily life. When using water cups, some people like to drink the water directly from the cup through the lid, while others prefer to drink the water from the cup through the straw on the lid.

[0003] A search revealed a patent document with authorization announcement number CN219920791 U, which discloses a double-drinking cup. The double-drinking cup includes a cup body and a cup lid spirally connected to the cup body. A detachable cup holder is provided on the bottom of the cup body. The cup lid is provided with a water outlet, a water inlet and a through hole inside the water outlet. The cup lid is provided with a rotating shaft and a limiting groove. The rotating shaft is provided with a limiting block corresponding to the limiting groove and a sealing cap for sealing the water outlet. A straw is provided inside the cup body and is connected to the water inlet. The cup lid is provided with a rotatable handle.

[0004] When using the aforementioned double-drink cup, water can be drunk directly or by sipping through the inlet and through-hole on the lid. However, both the inlet and through-hole are located inside the outlet. When the sealed lid is opened, both the inlet and through-hole open simultaneously, meaning they are not independent. If the user chooses to use either the inlet (or through-hole), the through-hole (or inlet) may become contaminated, causing inconvenience.

[0005] To address this issue, we propose a dual-drinking cup stopper. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a dual drinking cup stopper. This cup lid can not only meet two drinking methods, but also the two drinking methods are independent of each other and do not interfere with each other.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A dual-drinking cup stopper includes a cup lid body having a closed end and an open end. A straw is movably mounted on the cup lid body along its axial direction, with both ends of the straw passing through the closed end and the open end, respectively. The end of the straw that passes through the closed end can be opened and closed. A baffle is fixedly provided near the open end of the straw so that the baffle can open or block the open end when the straw moves on the cup lid body. The closed end of the cup lid body has a direct drinking spout for communicating with the inner cavity of the cup lid body, so that when the baffle opens the open end, the open end is connected to the direct drinking spout through the inner cavity of the cup lid body.

[0009] As a further embodiment of this utility model: the cup lid body is provided with a telescopic locking mechanism, which is used to lock the position of the straw so that when the baffle moves to the designated position with the straw, the telescopic locking mechanism can keep the baffle open or closed at the opening end.

[0010] As a further embodiment of this utility model: the telescopic locking mechanism includes a connecting cylinder with its closed end protruding into the inner cavity of the cup lid body. A pressure cylinder is coaxially arranged on the inner wall of the connecting cylinder, and the bottom of the pressure cylinder is serrated. A sliding groove is formed along the length of the pressure cylinder. The straw is slidably mounted on the sliding groove by the outer edge of the stepped structure. An upper toothed column and a lower toothed column are sequentially installed on the sliding groove below the outer edge of the stepped structure. The bottom of the upper toothed column is provided with cam teeth so that the bottom has multiple circumferentially arranged and undulating upward inclined wedge surfaces. Multiple guide blocks are arranged in a circumferential array on the side of the upper toothed column, and multiple guide blocks are arranged in a circumferential array on the side of the lower toothed column. Multiple protrusions are arranged, and the upper and lower toothed columns are slidably mounted on the slide groove by means of guide blocks and protrusions, respectively. Each protrusion has a lower inclined wedge surface at its top, and the lower inclined wedge surface and the upper inclined wedge surface are in a partially meshed inclined wedge engagement state. The upper toothed column can drive the lower toothed column to rotate by means of the engagement of the lower and upper inclined wedge surfaces. A key block is fixedly arranged on the outside of the straw. The upper and lower toothed columns are both sleeved on the outside of the straw, and the inner sides of the upper and lower toothed columns are respectively provided with a first notch and a second notch for the key block to pass through. The second notch can be staggered from the first notch as the lower toothed column rotates, so as to block the key block upward.

[0011] As a further embodiment of this utility model: the second notch is configured as multiple notches and is evenly distributed on the inner side of the lower tooth column.

[0012] As a further embodiment of this utility model: the cup lid body is provided with a frame protruding into its inner cavity, the baffle has an extension sleeve, and the extension sleeve is wrapped around the outside of the straw, the frame is provided with a first spring fixedly connected to the extension sleeve, and the first spring is sleeved on the outside of the extension sleeve.

[0013] As a further embodiment of this utility model: a second spring is provided on the outer edge of the stepped straw and fixedly connected to the upper toothed post, and the second spring is sleeved on the outside of the straw.

[0014] As a further embodiment of this utility model: an end cap is threadedly installed at the end of the straw that extends through the closed end.

[0015] As a further embodiment of this utility model, the outer surface of the cup lid body is provided with external threads.

[0016] As a further embodiment of this invention, a sealing ring is provided between the extension sleeve and the straw.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The advantage of this dual-drinking cup lid design lies in its innovative combination of straw and cup lid body. The straw passes through both the closed end and the open end, and a baffle is set at the position of the straw near the open end, realizing a dual drinking method of straw and direct drinking port, which is both convenient and practical, and meets the diverse drinking needs of users.

[0019] 2. This design adds a telescopic locking mechanism to the double drinking cup lid. The advantage of this feature is that it can lock the position of the straw, ensuring that the baffle can stably open or block the opening when it is in the designated position, thus improving the convenience and safety of use.

[0020] 3. Through the specific design of the telescopic locking mechanism, such as the pressure cylinder, slide groove, stepped outer edge, upper tooth column, and lower tooth column, the precise locking and unlocking of the straw position is achieved. The advantage of this design is that the structure is ingenious, the locking is stable, and the position of the straw can be flexibly adjusted according to different needs, thus improving the user experience.

[0021] 4. The design of setting multiple second notches and evenly distributing them on the inner side of the lower tooth post gives the locking mechanism more selectivity and flexibility when unlocking, thus improving the reliability and durability of the locking mechanism.

[0022] 5. By protruding a frame into the inner cavity of the cup lid body and setting a first spring on the frame that is fixedly connected to the extension sleeve, the advantage of this design is that it can effectively control the position of the baffle, ensuring that the baffle can stably open or block the opening end when needed, while increasing the durability and stability of the cup lid.

[0023] 6. A second spring is fixedly connected to the upper toothed column on the outer edge of the straw steps. The advantage of this design is that it can increase the stability of the straw in the slide, prevent the straw from shaking or falling off during movement, and improve the safety of the cup lid.

[0024] 7. The design of threaded end cap at the end of the straw that passes through the closed end allows the straw to be easily closed when not in use, preventing the intrusion of dust and bacteria and ensuring the hygiene and safety of drinking water.

[0025] 8. The design of external threads on the outside of the cup lid body makes it easy to fix the cup lid to the cup, improving the stability and practicality of the cup lid;

[0026] 9. The design of setting a sealing ring between the extension sleeve and the straw can effectively prevent water from seeping out from the gap between the straw and the extension sleeve, ensuring the sealing and waterproof performance of the cup lid and improving the use effect of the cup lid.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1-9 As shown, a double drinking cup stopper includes a cup lid body 1. The cup lid body 1 has external threads on its exterior, which can be used to screw the cup lid body 1 onto the corresponding drinking cup.

[0040] The two ends of the cup lid body 1 are a closed end 101 and an open end 102, respectively. A straw 2 is movably installed on the cup lid body 1 along its axial direction. The two ends of the straw 2 pass through the closed end 101 and the open end 102, respectively. An end cap 10 is threaded onto the end of the straw 2 that passes through the closed end 101. When you need to drink water, you can suck water from the drinking cup through the straw 2. This is the first drinking method.

[0041] A baffle 3 is fixedly installed near the opening end 102 of the straw 2. The movement of the straw 2 on the cup lid body 1 can cause the baffle 3 to move accordingly. Under normal circumstances, the baffle 3 is located below the opening end 102 and is sealed to the opening end 102. When the straw 2 is driven to move downward, the baffle 3 will move accordingly and open the opening end 102. Furthermore, a direct drinking spout 4 for communicating with the inner cavity of the cup lid body 1 is provided at the closed end 101 of the cup lid body 1. When the baffle 3 opens the opening end 102, the user can tilt the drinking cup so that the water in the drinking cup flows sequentially to the opening end 102 and the inner cavity of the cup lid body 1, and finally flows to the direct drinking spout 4 for the user to drink directly. This is the second drinking method.

[0042] It should be noted that the movement of the straw 2 on the cup lid body 1 can be driven directly by the user's hand or automatically operated by means of the telescopic locking mechanism 5.

[0043] (1) When the straw 2 is operated by the user’s hand, the straw 2 is pre-locked on the cup lid body 1. Then the user can use his hand to drive the straw 2 downward so that the baffle 3 opens the opening end 102. At this time, the user drinks water through the drinking port 4. At the same time, the hand needs to ensure that the position of the straw 2 is fixed. After drinking, the user needs to use his hand to move the straw 2 upward again to reset it to the initial locked state.

[0044] (2) When a telescopic locking mechanism 5 is provided on the cup lid body 1, the telescopic locking mechanism 5 is used to lock the position of the straw 2 in the initial state and the drinking state, so that when the baffle 3 is driven downward with the straw 2 to the designated position, the telescopic locking mechanism 5 can keep the baffle 3 open to the opening end 102. After drinking, the baffle 3 can be reset upward again by the telescopic locking mechanism 5 to block the opening end 102.

[0045] like Figures 4-9As shown, it should be noted that the telescopic locking mechanism 5 mentioned above is the same as the telescopic locking mechanism used in the existing automatic telescopic pen. The two have the same composition and working principle, which will be briefly introduced below:

[0046] The telescopic locking mechanism 5 includes a connecting cylinder 501 protruding from the closed end 101 into the inner cavity of the cup lid body 1. A pressure cylinder 502 is coaxially arranged on the inner wall of the connecting cylinder 501, and the bottom of the pressure cylinder 502 is serrated. A sliding groove 503 is formed on the pressure cylinder 502 along its length. The straw 2 is slidably mounted on the sliding groove 503 by means of its outer stepped edge 504. An upper toothed column 505 and a lower toothed column 506 are sequentially installed on the sliding groove 503 below the outer stepped edge 504. The bottom of the upper toothed column 505 is provided with cam teeth 507 so that the bottom has multiple circumferential arrays arranged in an undulating shape. The upper inclined wedge surface 5071, the upper tooth column 505 is provided with a plurality of guide blocks 5052 arranged in a circumferential array on the side, and the lower tooth column 506 is provided with a plurality of protrusions 508 arranged in a circumferential array on the side. The upper tooth column 505 and the lower tooth column 506 are slidably mounted on the slide groove 503 by means of the guide blocks 5052 and the protrusions 508 respectively. Each protrusion 508 is provided with a lower inclined wedge surface 5081 on its top. The lower inclined wedge surface 5081 and the upper inclined wedge surface 5071 are in a partially meshed inclined wedge engagement state. The upper tooth column 505 can drive the lower tooth column 506 to rotate by means of the engagement of the lower inclined wedge surface 5081 and the upper inclined wedge surface 5071.

[0047] Based on the above-mentioned institutional design, this application makes the following improvements:

[0048] (1) As Figures 5-9 As shown, a key block 6 is fixedly installed on the outside of the straw 2. The upper toothed post 505 and the lower toothed post 506 are both sleeved on the outside of the straw 2. The inner sides of the upper toothed post 505 and the lower toothed post 506 are respectively provided with a first notch 5051 and a second notch 5061 for the key block 6 to pass through. The second notch 5061 is set in multiples and is evenly distributed on the inner side of the lower toothed post 506.

[0049] (2) Figure 4 As shown, the cup lid body 1 has a frame 7 protruding into its inner cavity, the baffle 3 has an extension sleeve 301, and the extension sleeve 301 is wrapped around the outside of the straw 2. A sealing ring 11 is provided between the extension sleeve 301 and the straw 2. A first spring 8 is provided on the frame 7 and is fixedly connected to the extension sleeve 301, and the first spring 8 is sleeved on the outside of the extension sleeve 301.

[0050] (3) Figure 5 As shown, a second spring 9 is provided on the outer edge 504 of the stepped straw 2 and is fixedly connected to the upper toothed post 505, and the second spring 9 is sleeved on the outside of the straw 2.

[0051] The workflow is as follows: Driving the straw 2 downwards causes the key block 6 outside the straw 2 to pass sequentially through the relatively arranged first notch 5051 and second notch 5061. The baffle 3 also opens the opening end 102. As the straw 2 continues to descend, the outer edge 504 of the step on the straw 2 moves downwards, pressing against the upper toothed column 505 and causing it to move downwards. This, in turn, drives the lower toothed column 506 downwards until the protrusion 508 on the lower toothed column 506 moves out of the groove 503 on the pressure cylinder 502. Then, the protrusion 50... 8 will first engage with the sawtooth wedge at the bottom of the pressure cylinder 502. At this time, the lower toothed column 506 will rotate and then engage with the sawtooth. The position of the second notch 5061 will be offset from the position of the first notch 5051, that is, the second notch 5061 and the first notch 5051 will be misaligned. The first spring 8 will be compressed, and the key block 6 on the straw 2 will be blocked by the lower toothed column 506 and will not be able to move upward. The position of the straw 2 will be locked, and the user can drink water through the drinking port 4. When it is necessary to release the lock on straw 2 and close the opening end 102, straw 2 can be driven downward again, so that the outer edge 504 of the step of straw 2 presses against the upper tooth post 505 and moves downward. The upper tooth post 505 applies pressure to the lower tooth post 506, so that the lower tooth post 506 disengages from the sawtooth at the bottom of the pressure cylinder 502. At this time, the lower tooth post 506 will perform a reverse reset rotation action, and the protrusion 508 on the lower tooth post 506 will slide back into the groove 503 on the pressure cylinder 502. The reverse rotation of the lower tooth post 506 can reset the second notch 5061 to be opposite to the position of the first notch 5051. Under the elastic reset action of the first spring 8, straw 2 is subjected to an upward reset action, and then the key block 6 outside straw 2 can automatically pass through the second notch 5061 and the first notch 5051 in sequence. Straw 2 will drive the bottom baffle 3 to seal the opening end 102.

[0052] Of course, the telescopic locking mechanism 5 mentioned above is the preferred mechanism for implementing this application. In actual use, this application may choose not to set the telescopic locking mechanism 5 to manually control the movement of the straw; or it may set other mechanisms in the prior art to lock the position of the straw 2, such as conventional locking structures in the prior art.

[0053] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
