Description

Technical Field

[0001] This utility model relates to drinking water appliances, and more particularly to a cup lid and a water cup with a progressive unlocking function. Background Technology

[0002] Existing flip-top water bottles, especially those with fingerprint recognition, only use fingerprint recognition to control whether the flip is opened or closed, and cannot directly control whether the entire lid is opened from the bottle. Therefore, water bottles with a design that links the control of the flip opening with the control of the entire lid opening from the bottle have emerged. For example, the invention patent publication CN118948076A discloses a lid and liquid containing device, comprising: a screw thread assembly, installed on and rotatably connected to the end of the bottle body, with a spout inside the screw thread assembly; an outer rotating assembly, fitted outside the screw thread assembly and movably connected to it; a cup cover covering the outer rotating assembly; and a cup that can rotate relative to the outer rotating assembly. The components open and close; a locking mechanism is installed between the threaded assembly and the outer rotating assembly, and is used to control the fixed connection and movable connection between the threaded assembly and the outer rotating assembly; after the cup is closed, the locking mechanism makes the threaded assembly and the outer rotating assembly movablely connected, and the threaded assembly does not rotate relative to the cup body, so that the outer rotating assembly and the threaded assembly cannot be detached from the cup body; after the cup is opened, the locking mechanism makes the outer rotating assembly and the threaded assembly fixedly connected, and can make the threaded assembly and the outer rotating assembly rotate synchronously, so that the outer rotating assembly and the threaded assembly detach from the cup body.

[0003] In the aforementioned patent application, the cup lid is configured as two movably connected parts: an outer rotating component and a screw-tooth component. The screw-tooth component is rotatably connected to the end of the cup body, and the outer rotating component is fitted onto the outside of the screw-tooth component. A locking mechanism controls the fixed connection and movable connection between the screw-tooth component and the outer rotating component. The locking mechanism is locked or unlocked by opening or closing the cup lid, thereby achieving control over whether the two parts of the cup lid are locked or not. However, when the lid is closed, the locking mechanism unlocks both parts of the lid in both directions around the circumference. Both parts of the lid can rotate freely in both directions around the circumference. Therefore, when screwing the entire lid onto or off the cup body, the lid must be in the open position. When it is necessary to unscrew the lid to add water, the lid must first be opened before the entire lid can be screwed off the cup body. This operation is cumbersome, and the cup body with the lid open takes up a lot of space and is not easy to place. In addition, the exposed spout poses a problem for drinking hygiene and safety. After adding water, the lid with the lid open is screwed back onto the cup body, and then the lid is closed to complete the lid closing operation. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cup lid and a water cup with a progressive unlocking function, so that the cup lid can be screwed onto the cup body without opening the flip cover, and the cup lid screwed onto the cup body cannot be screwed off the cup body in the opposite direction when the flip cover is closed, thus avoiding accidental unscrewing of the cup lid.

[0005] This utility model is achieved through the following technical solution:

[0006] A cup lid with a progressive unlocking function includes a cup lid body and a flip cover that is rotatably connected to the cup lid body;

[0007] The cup lid body is rotatably mounted with a rotating cover inside. The rotating cover includes two rings, an outer ring and an inner ring. The gap between the outer ring and the inner ring of the rotating cover forms an annular groove for the mouth of the cup to be inserted. The cup lid is installed on the cup body by the annular groove of the rotating cover and the threaded engagement of the mouth of the cup body.

[0008] A locking element is vertically slidable in the locking cavity inside the cup lid body. An elastic element for supporting the locking element upward is also installed inside the cup lid body. When the lid is closed, the guide post at the top of the locking element is in a downward pressing state, and the circumferential rotation between the rotating lid and the cup lid body is locked in one direction. When the lid is opened, the guide post is released from the pressing state, and the circumferential rotation between the rotating lid and the cup lid body is locked.

[0009] As a preferred embodiment of the aforementioned cup lid, the inner ring of the rotating lid has an annular toothed ring on its inner side wall. The bottom of the annular toothed ring has multiple positioning teeth evenly distributed circumferentially, with a positioning gap between adjacent positioning teeth. The locking member is located in the inner ring of the rotating lid. The locking member has an arc-shaped locking side concentric with the rotating lid on the side facing the rotating lid. The bottom of the locking side of the locking member has an upwardly extending limiting tooth. The top surface of the limiting tooth is a first inclined surface circumferentially inclined, and the bottom surface of the positioning tooth of the annular toothed ring is a second inclined surface circumferentially inclined.

[0010] When the locking element is released from the compressed state, the limiting tooth is fully embedded in the positioning gap of the ring tooth ring, and the bidirectional circumferential rotation of both the limiting tooth and the ring tooth ring is locked.

[0011] When the locking member is in a downward pressing state, the inclined surface between the first inclined surface of the limiting tooth and the second inclined surface of the positioning tooth of the ring gear locks the unidirectional rotation of both the limiting tooth and the ring gear in a single direction.

[0012] As a preferred embodiment of the cup lid, the bottom of the cup lid body is provided with an annular support section that protrudes downward from the bottom of the rotating lid.

[0013] As a preferred embodiment of the above-mentioned cup lid, the cup lid body is composed of an inner lid and an outer lid that are fixedly connected. The top of the inner lid is provided with a drinking spout, which extends upward from the central hole at the top of the outer lid. An annular support section is provided at the bottom of the outer lid, and an annular mounting cavity is formed between the inner lid and the outer lid. The rotating lid is rotatably mounted in the annular mounting cavity. The bottom of the inner lid is provided with a ring of outwardly protruding limiting flanges, which provide rotational support and limit the bottom of the inner ring of the rotating lid. The bottom of the outer ring of the rotating lid protrudes downward from the bottom of the inner ring.

[0014] As a preferred embodiment of the aforementioned cup lid, the two sides of the locking member and the two side walls of the locking cavity are slidably connected by sliding engagement of slide rails and slide grooves.

[0015] As a preferred embodiment of the aforementioned cup lid, the bottom of the flip lid is provided with a protruding post, and the flip lid presses down on the guide post of the locking component through the protruding post.

[0016] This utility model also discloses a water cup, including a cup body and a cup lid, wherein the cup lid is the cup lid described above.

[0017] As a preferred embodiment of the aforementioned water cup, the bottom of the cup lid body is provided with a ring-shaped support section that protrudes downward from the bottom of the rotating lid, and a positioning step is provided on the outer wall of the cup body. When the cup lid is closed on the cup body, the positioning step of the cup body and the ring-shaped support section of the cup lid are in inner and outer contact.

[0018] This invention has the following advantages over the prior art:

[0019] This utility model provides a cup lid and a water cup with a progressive unlocking function. Through the linkage design of the flip lid, locking component and rotating lid, it realizes that when the flip lid is open, the circumferential movement of the rotating lid and the cup lid body is locked in both directions. At this time, the rotating lid can rotate together with the rotation of the cup lid body. When the flip lid is closed, the circumferential movement between the rotating lid and the cup lid body is locked in only one direction. Thus, it is possible to screw the cup lid onto the cup body without opening the flip lid, and the cup lid can also be screwed onto the cup body when the flip lid is closed. Moreover, after tightening, the cup lid body can only be rotated counterclockwise without unscrewing the cup body, which can effectively avoid accidental opening of the lid and ensure drinking safety. Meanwhile, a ring-shaped support section is provided at the bottom of the lid body, and the positioning steps of the cup body abut against this ring-shaped support section. This effectively prevents the lid body from deforming and squeezing the rotating lid inward. This ensures that once the lid is screwed onto the cup body, forceful squeezing and twisting will not remove it, further preventing accidental opening. Furthermore, when used with the flip-top lid featuring fingerprint recognition, only a specific fingerprint can open the flip-top and then the lid, ensuring that only specific individuals can open the corresponding lid, thus guaranteeing drinking water safety.

[0030] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0031] See Figures 1 to 9This embodiment discloses a water cup, including a cup body 1 and a cup lid, the cup lid being a cup lid with a progressive unlocking function. The cup lid includes a cup lid body and a flip cover 2 rotatably connected to the cup lid body. The rear side of the flip cover 2 is hinged to the rear side of the cup lid body. The cup lid body has an annular mounting cavity with an open bottom. A rotating cover 3 is rotatably disposed in the annular mounting cavity. The rotating cover 3 can rotate circumferentially in the annular mounting cavity. The rotating cover 3 includes inner and outer rings. The gap between the outer ring 4 and the inner ring 5 of the rotating cover 3 forms an annular groove 6 for the mouth of the cup body 1 to be inserted. The cup lid is installed on the cup body 1 by threaded engagement between the annular groove 6 of the rotating cover 3 and the mouth of the cup body 1.

[0032] A locking element 8 is vertically slidable within the locking cavity 7 inside the cup lid body. The locking element 8 is slidably connected to the side walls of the locking cavity 7 via slide rails 9 and slide grooves 10, ensuring that the locking element 8 can only slide vertically and cannot move laterally or rotate circumferentially. An elastic element is also installed inside the cup lid body to support the locking element 8 upwards. This elastic element, which can be a spring 11, provides elastic support to the locking element 8 via the elastic element on the bottom wall of the locking cavity 7. A protruding post 12 is provided at the bottom of the flip cover 2, which presses down on the guide post 13 at the top of the locking element 8. When the flip cover 2 is closed, the protrusion 12 of the flip cover 2 presses down on the top guide post 13 of the locking member 8, so that the locking member 8 is in a downwardly compressed state, and the circumferential rotation between the rotating cover 3 and the cup lid body is locked in a single direction; when the flip cover 2 is opened, the guide post 13 is released, and under the elastic force of the elastic member, the guide post 13 extends upward from the guide hole 14 on the top wall of the cup lid body, the locking member 8 is released from the compressed state, and the circumferential rotation between the rotating cover 3 and the cup lid body is locked.

[0033] The inner wall of the inner ring 5 of the rotating cover 3 is provided with an annular toothed ring 15. The bottom of the annular toothed ring 15 is provided with a plurality of positioning teeth 16 evenly distributed along the circumference. A positioning gap 17 is left between adjacent positioning teeth 16. The locking member 8 is located in the inner ring of the rotating cover 3. The side of the locking member 8 facing the rotating cover 3 is an arc-shaped locking side concentric with the rotating cover 3. The bottom of the locking side of the locking member 8 is provided with an upwardly extending limiting tooth 18. There is at least one limiting tooth 18 on the locking member 8. In this embodiment, there are two limiting teeth 18 distributed along the circumference. The top surface of the limiting tooth 18 is a first inclined surface 19 inclined along the circumference. The bottom surface of the positioning teeth 16 of the annular toothed ring 15 is a second inclined surface 20 inclined along the circumference.

[0034] When the locking member 8 is released from the compressed state, the limiting tooth 18 is fully embedded in the positioning gap 17 of the annular tooth ring 15, and both the limiting tooth 18 and the annular tooth ring 15 are locked in both directions of circumferential rotation; when the locking member 8 is in the downward compressed state, under the inclined surface cooperation between the first inclined surface 19 of the limiting tooth 18 and the second inclined surface 20 of the positioning tooth 16 of the annular tooth ring 15, the unidirectional circumferential rotation of both the limiting tooth 18 and the annular tooth ring 15 is locked.

[0035] The bottom of the cup lid body has a downward-protruding annular support section 21 extending from the bottom of the rotating lid 3. A positioning step 22 is provided on the outer wall of the cup body 1. When the cup lid is closed on the cup body 1, the positioning step 22 of the cup body 1 and the annular support section 21 of the cup lid abut against each other. The annular support section 21 at the bottom of the cup lid body, along with the positioning step 22 of the cup body 1 abutting against the annular support section 21 of the cup lid body, effectively prevents the cup lid body from deforming and squeezing the rotating lid 3 inward. This avoids the situation where force is directly transmitted to the rotating lid 3 when force is applied to the cup lid body circumferentially, causing it to rotate and leading to accidental opening. This ensures that when the cup lid is closed and screwed onto the cup body 1, forceful squeezing and rotating the cup lid will not unscrew it, preventing accidental opening due to misoperation.

[0036] The cup lid body consists of an inner lid 23 and an outer lid 24 fixedly connected. The inner lid 23 has a drinking spout 25 at its top, which extends upwards from the central hole at the top of the outer lid 24. The drinking spout 25 is sealed by a sealing plug 26 at the bottom of the flip-top lid 2. An annular support section 21 is located at the bottom of the outer lid 24, forming an annular mounting cavity between the inner lid 23 and the outer lid 24. The rotating lid 3 is rotatably mounted within this cavity. The bottom of the inner lid 23 has an outwardly protruding limiting flange 27, which provides rotational support and limits the bottom of the inner ring 5 of the rotating lid 3. The bottom of the outer ring 4 of the rotating lid 3 protrudes downwards from the bottom of the inner ring 5. A sealing ring 28 is embedded at the bottom of the inner lid 23 below the limiting flange 27, sealing the gap between the cup lid and the mouth of the cup body 1.

[0037] The inner cover 23 and the outer cover 24 are connected by a snap-fit ​​mechanism. Specifically, the outer cover 24 has an outer connecting ring 29 near its center at the bottom, and the inner cover 23 has an inner connecting ring 30 at its top, located around the drinking spout 25. The inner connecting ring 30 and the outer connecting ring 29 fit together in an inner-outer, ...

[0038] The top of the outer cover 24 has a first latching part 35 located in front of the drinking spout 25, and the bottom of the flip cover 2 has a second latching part 36 near the front. When the flip cover 2 is closed, the second latching part 36 of the flip cover 2 engages with the first latching part 35 of the outer cover 24. The flip cover 2 may be a flip cover with fingerprint recognition function, allowing the flip cover 2 to be opened or closed by fingerprint recognition.

[0039] When the flip cover 2 is opened, the guide post 13 of the locking member 8 is released, and the spring 11 pushes the locking member 8 upward, causing the locking member 8 to be released from the squeezed state. At this time, the two limiting teeth 18 of the locking member 8 are fully embedded in the two adjacent positioning gaps 17 of the annular toothed ring 15. The rotating cover 3 is locked in both directions by the limiting teeth 18, and the rotating cover 3 can rotate synchronously with the rotation of the cup cover body; thus, by rotating the outer cover 24 counterclockwise, the entire cup cover can be unscrewed off the cup body 1.

[0040] When the flip cover 2 is closed, the protrusion 12 at the bottom of the flip cover 2 presses down on the guide post 13 of the locking member 8, the spring 11 is compressed, and the locking member 8 is pressed down and is in a downward squeezed state. At this time, the lower end of the top surface of the limiting tooth 18 disengages from the bottom end of the side wall corresponding to the positioning gap 17, while the higher end of the top surface of the limiting tooth 18 has not yet disengaged from the bottom end of the side wall corresponding to the positioning gap 17. At this time, the rotating cover 3 can rotate freely in the clockwise direction relative to the limiting tooth 18, but is locked in the counterclockwise direction and cannot rotate. That is, at this time, the circumferential rotation of the rotating cover 3 is locked in one direction. In this state, the entire cup lid with the flip cover 2 closed can be screwed clockwise onto the cup body 1. After it is screwed onto the cup body 1, if the outer cover 24 is rotated counterclockwise, the limiting tooth 18 will rotate counterclockwise along with the outer cover 24. Under the action of the inclined surfaces between the first inclined surface 19 and the second inclined surface 20, the rotating cover 3 will not rotate with the outer cover 24. Only the outer cover 24 will rotate counterclockwise. Therefore, the rotating cover 3 will not be screwed off the cup body 1, effectively avoiding opening the lid due to misoperation.

[0041] The water cup provided in this embodiment allows the lid to be screwed onto the cup body 1 without opening the flip cover 2. Even with the flip cover 2 closed, the entire lid can be screwed clockwise onto the cup body 1, eliminating the need to open the flip cover 2 first. This makes the lid-screwing operation convenient and quick. After the lid is tightened onto the cup body 1, with the flip cover 2 not engaged, turning the lid counterclockwise only causes the lid body to rotate freely; it does not cause the rotating cover 3 to rotate counterclockwise. Therefore, the lid cannot be unscrewed from the cup body 1. In other words, the lid cannot be unscrewed when the flip cover 2 is closed. Only when the flip cover 2 is open can the lid be unscrewed counterclockwise from the cup body 1. This effectively prevents accidental opening due to misoperation. Furthermore, when combined with the flip cover 2 featuring fingerprint recognition, only a specific fingerprint can open the flip cover 2, allowing the lid to be opened further. This ensures that only specific individuals can open the corresponding lid, guaranteeing drinking water safety.

[0042] When adding water to the cup body 1, first open the flip cover 2, then unscrew the cup lid counterclockwise, and then close the flip cover 2 and place the cup lid. At this time, the cup lid can be placed upside down for easy placement, and the drinking spout 25 is not exposed, ensuring the hygiene and safety of drinking water. After adding water, simply screw the cup lid with the flip cover 2 closed onto the cup body 1 clockwise. The whole operation is convenient and quick.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
