Description

Technical Field

[0001] This utility model relates to the field of drinking water container technology, specifically to a cup lid, and also discloses a large-capacity water cup that can be operated with one hand. Background Technology

[0002] A water cup is a container for drinking water, coffee, milk tea, and other beverages. For ease of carrying, insulation, and use, a lid can be added to the rim, creating a thermos. If the capacity is increased, it can be called a water bottle (or flask). Therefore, water cups come in many styles and have diverse functions, making them an indispensable tool in daily life. Traditional water cup lids typically use a screw-on connection to the rim, offering good sealing but requiring both hands to open and close. Some water cups feature a flip-top design, where the lid is pivotally mounted on a sealing base. This allows the lid to spring open automatically, especially popular models with spouts.

[0003] Chinese patent CN221044706U discloses a quick-opening water cup, comprising a cup body and a lid that fits onto the cup body. The lid includes a lid body and a rotating lid. One end of the rotating lid is hinged to one end of the lid body. The lid body has a drinking spout. The lid body has a control block. One end of the control block extends to form a locking block. The other end of the rotating lid has a locking part that engages with the locking block. The lid body also has a sliding member for driving the control block. The inner side of the sliding member has a sliding inclined surface. The other end of the control block has a control inclined surface that matches the sliding inclined surface. Driving the sliding member downward causes the sliding inclined surface to abut against the control inclined surface. The control block moves inward, causing the locking block to disengage from the locking part. At this time, the rotating lid can rotate relative to the lid body.

[0004] The problem with the aforementioned existing technology is that when a user holds the cup with one hand, it is difficult for the index finger or thumb to push the slider downwards to open the lid. This is especially true for large-capacity water cups, where the stability of holding the cup with one hand conflicts with the dexterity of finger operation, making it difficult to operate with one hand. This does not solve the problem of inconvenience in one-handed operation and affects the user experience.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0025] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-5As shown, the cup lid of this utility model includes a lid body 100 and a flip cover 1. The flip cover 1 is connected to the lid body 100 via an elastic hinge. The flip cover 1 is provided with a locking hook 11, and a locking control assembly is provided inside the lid body 100. The locking control assembly includes a locking control slide plate 2, a linkage slide plate 3, and a spring 21. A push-button switch 101 is provided on one side of the lid body 100. The push-button switch 101 is connected to the linkage slide plate 3, thereby driving it to slide within the lid body 100 in a first direction. The locking control slide plate 2 is disposed on the linkage slide plate 3, and the locking hook 11 can extend into the lid body 100 and be paired with the locking control slide plate 2. The linkage slide plate 3 is connected to the locking control slide plate 2 via a linkage structure, thereby driving it to slide forward within the lid body 100 in a second direction. The spring 21 is connected to the locking control slide plate 2, thereby driving it to slide in the reverse direction within the lid body 100. The first direction is parallel to the rotation axis of the elastic hinge on the horizontal projection plane, and the second direction is intersecting the first direction on the horizontal projection plane.

[0027] It is understood that the flip cover 1 is connected to the cover body 100 by an elastic hinge, allowing it to flip back and forth relative to the cover body 100 around a rotation axis. The cover body 100 is provided with a drinking tube 4. When the flip cover 1 is fastened on the upper end surface of the cover body 100, it can cover and seal the upper port of the drinking tube 4. The sealing method of the flip cover 1 can be adjusted according to the actual situation, which will be detailed later.

[0028] When the flip cover 1 is fastened onto the cover body 1, it can be connected to the locking control slide plate 2 through the locking hook 11. The locking hook 11 is fastened onto the locking control slide plate 2, and at this time the locking control component restricts the flip cover 1 to be in a locked state.

[0029] When the button switch 101 is pressed, the button switch 101 pushes the linkage slide plate 3 to slide in the first direction. The linkage slide plate 3 drives the locking slide plate 2 to slide in the second direction through the linkage structure, so that the locking slide plate 2 releases the locking hook 11, and the flip cover 1 automatically pops up under the action of the elastic hinge to open the cover.

[0030] Preferably, with the horizontal projection plane as a reference, the first direction and the second direction are intersected in a cross shape, and the rotation axis of the elastic hinge is parallel to the first direction. When the user holds the water cup with one hand and presses the button switch 101 with his thumb, the hand posture is similar to the right hand rule (electromagnetic induction). The button switch 101 pushes the linkage slide plate 3 to slide along the first direction. The linkage slide plate 3 drives the locking slide plate 2 to slide along the second direction through the linkage structure. The flip cover 1 can rotate away from the user around the rotation axis of the elastic hinge, thereby avoiding interference with the user's drinking action and making it convenient for the user to open the cover with one hand.

[0031] The cover 100 includes a bottom cover 102 and a top cover 103. The flip cover 1 is connected to the top cover 103 via an elastic hinge. The top cover 103 is fastened to the bottom cover 102. A directional frame 104 is provided between the top cover 103 and the bottom cover 102, and the directional frame 104 forms an action cavity 105 between the top cover 103 and the bottom cover 102. The linkage slide plate 3 cooperates with the directional frame 104, so that the linkage slide plate 3 can slide in the action cavity 105 above the bottom cover 102 along a first direction. The locking slide plate 2 is provided between the linkage slide plate 3 and the top cover 103. The locking slide plate 2 cooperates with the directional frame 104, so that the locking slide plate 2 can slide in the action cavity 105 below the top cover 103 along a second direction.

[0032] The bottom cover 102 and the top cover 103 together form a cover body 100 and a cavity. A directional frame 104 is disposed between the top cover 103 and the bottom cover 102 to enclose an action cavity 105 for assembling the linkage slide plate 3 and the locking slide plate 2, and controlling their movement direction. Preferably, the action cavity 105 enclosed by the directional frame 104 is rectangular on the horizontal projection plane, and both the locking slide plate 2 and the linkage slide plate 3 are rectangular structures.

[0033] The directional frame 104 is used to assemble and control the movement direction of the locking slide plate 2 and the linkage slide plate 3. Specifically, the length of the linkage slide plate 3 in the first direction is less than the length of the actuation cavity 105, and the width of the linkage slide plate 3 in the second direction matches the width of the actuation cavity 105, so that the linkage slide plate 3 can slide within the actuation cavity 105 along the first direction. The length of the locking slide plate 2 in the first direction matches the length of the actuation cavity 105, and the width of the locking slide plate 2 in the second direction is less than the width of the actuation cavity 105, so that the locking slide plate 2 can slide within the actuation cavity 105 along the second direction.

[0034] The locking slide plate 2 and the linkage slide plate 3 are stacked one on top of the other inside the actuation cavity 105, and the linkage slide plate 3 is connected to the locking slide plate 2 via a linkage structure. Simply put, when the linkage slide plate 3 slides between the locking slide plate 2 and the bottom cover 102, the locking slide plate 2 slides between the linkage slide plate 3 and the top cover 103.

[0035] Specifically, there is a sliding gap between the linkage slide plate 3 and the two side walls of the directional frame 104. Several anti-friction ribs 33 are provided on both end walls of the directional frame 104. The anti-friction ribs 33 fit against the end edges of the linkage slide plate 3 to form a sliding fit, thereby allowing the linkage slide plate 3 to slide within the action cavity 105 along the first direction. The two end walls of the directional frame 104 restrict the movement trajectory of the linkage slide plate 3. The two sides of the first direction are the end walls of the centering frame 104. The anti-friction ribs 33 reduce the frictional resistance between the linkage slide plate 3 and the end walls of the directional frame 104. It can be understood that the bottom cover 102 and the bottom surface of the linkage slide plate 3 form a sliding fit, allowing the linkage slide plate 3 to slide within the action cavity 105 along the first direction.

[0036] Specifically, there is a sliding gap between the locking slide plate 2 and the two end walls of the directional frame 104. Guide hooks 28 are provided on both side walls of the directional frame 104. The two sides of the locking slide plate 2 are respectively inserted into the corresponding guide hooks 28, allowing the locking slide plate 2 to slide within the actuating cavity 105 along the second direction. The guide hooks 28 support the locking slide plate 2 to keep it close to the panel and leave a gap between the locking slide plate 2 and the linkage slide plate 3 to reduce frictional resistance.

[0037] Furthermore, multiple guide hooks 28 are symmetrically arranged on both sides of the directional frame 104, and the two sides of the locking slide plate 2 are respectively inserted into the corresponding guide hooks 28, so that the locking slide plate 2 can slide relative to the face cover 103, thereby allowing the linkage slide plate 3 to slide in the action cavity 105 along the first direction.

[0038] Furthermore, the upper surface of the locking slide plate 2 is provided with a number of friction-reducing protrusions 25 that abut against the cover 103, thereby reducing the friction between the locking slide plate 2 and the cover 103 and improving the flexibility of the locking slide plate 2 within the action cavity 105.

[0039] The linkage structure includes a linkage groove 31 and a guide slider 23. The linkage slide plate 3 has at least one linkage groove 31, and the locking slide plate 2 has at least one guide slider 23. The guide slider 23 is movably inserted into the linkage groove 31. The linkage groove 31 has a pushing inclined surface 32, and each guide slider 23 has a sliding inclined surface 24. The pushing inclined surface 32 and the sliding inclined surface 24 are paired to form a sliding fit. When the linkage slide plate 3 slides in the first direction, it can push the locking slide plate 2 to slide in the second direction. The guide slider 23 is inserted into the linkage groove 31. When the linkage slide plate 3 slides in the first direction, the pushing inclined surface 32 compresses the sliding inclined surface 24, generating a component force that causes the locking slide plate 2 to slide in the second direction.

[0040] The linkage slide plate 3 is connected to the locking slide plate 2 via an inclined surface, which can reduce the transmission path and improve handling stability. It is understood that the linkage slide plate 3 can be provided with two or more linkage grooves 31, while the locking slide plate 2 can be provided with two or more guide sliders 23.

[0041] The pushing inclined surface 32 and / or sliding inclined surface 24 are provided with friction-reducing ribs 33, and the friction-reducing ribs 33 on the pushing inclined surface 32 and the friction-reducing ribs 33 on the sliding inclined surface 24 are staggered. As mentioned above, the linkage slide plate 3 is connected to the locking slide plate 2 through the inclined surface. There is friction between the two in the transmission method. By using the staggered friction-reducing ribs 33, the friction between the pushing inclined surface 32 and the sliding inclined surface 24 can be reduced, and the flexibility of the locking slide plate 2 can be improved.

[0042] Preferably, the first direction and the second direction are perpendicular to each other on the horizontal projection plane, which makes the design of the locking slider 2, the linkage slider 3, and the cover 100 more regular and facilitates mold production. In particular, corresponding to the above-mentioned pushing slope 32 and sliding slope 24, the horizontal and vertical movement trajectories of the locking slider 2 and the linkage slider 3 can better set the angles of the pushing slope 32 and the sliding slope 24. Of course, the inclination angle of the pushing slope 32 and the sliding slope 24 is usually 45°, which can equally divide the driving force of the button switch 101 and the restoring force of the spring 21.

[0043] Furthermore, by changing the tilt angles of the aforementioned pushing ramp 32 and sliding ramp 24, a better feel and locking stability of the locking slider 2 can be provided. It is understood that the force required for the locking stability of the locking slider 2 is provided by the spring 21.

[0044] The locking slide plate 2 has a slot 26, and a bolt 27 is provided in the slot 26. One end of the spring 21 is fitted onto the bolt 27, thereby contacting and connecting the locking slide plate 2. The other end of the spring 21 contacts and connects to the end wall of the directional frame 104, so that the spring 21 can push the locking slide plate 2 to slide in the opposite direction. The spring 21 is used to drive the locking slide plate 2 to reset, and then, through the sliding inclined surface 24, the pushing inclined surface 32 is pressed and driven to reset the linkage slide plate 3. It can be understood that when the locking slide plate 2 and the linkage slide plate 3 are reset, the flip cover 1 can be in an open state, or in a locked state through the locking hook 11 and the lock hole slide plate 2.

[0045] The upper surface of the cover 103 has an opening 12 that vertically penetrates the actuation cavity 105. The locking slide plate 2 has a keyhole 22, and the locking hook 11 can pass through the opening 12 and be fastened to the keyhole 22. The elastic hinge includes a hinge seat 13, a pivot 14, and a torsion spring 15. The hinge seat 13 is fixedly mounted on the cover 103. The flip cover 1 has a coupling seat 16, and the pivot 14 passes through the hinge seat 13 and the coupling seat 16, so that the flip cover 1 and the cover 103 can be rotatably connected. The torsion spring 15 is fitted on the pivot 14, and the two ends of the torsion spring 15 are respectively connected to the hinge seat 13 and the coupling seat 16. The opening principle of the elastic hinge is the same as that of the prior art, so it will not be described in detail here.

[0046] The side wall of the cover 103 is provided with an operation hole 106 that runs horizontally through the action cavity 105. The button switch 101 passes through the operation hole 106 and is paired with the linkage slide plate 3. The button switch 101 and the linkage slide plate 3 move in the same direction. Pressing the button switch 101 can drive the linkage slide plate 3 to move in the first direction (towards the inside of the cover 100). When the button switch 101 is released, the linkage slide plate 3 can move in the opposite direction in the first direction.

[0047] This utility model also includes a locking key 109. A locking hole 107 is provided on the side wall of the cover 103. The locking hole 107 is close to the operating hole 106, and a locking groove 108 is provided between them for communication. The locking key 109 is slidably inserted into the locking groove 108. A lever is provided on the locking key 109, which can movably pass through the locking hole 107 and protrude from the outer side wall of the cover 103. The locking key 109 can slide along the locking groove 108 and insert into the push-button switch 101, preventing the push-button switch from sliding along the operating hole 106 and preventing the flip cover 1 from being accidentally triggered.

[0048] The face cover 103 is provided with a drinking tube 4. The flip cover 1 can be fastened onto the face cover 103 to cover the drinking tube 4. The drinking tube 4 passes through several adapter holes 41 to connect to a water cup, so that water can be drunk directly through the drinking tube 4.

[0049] Furthermore, the locking slide plate 2, the linkage slide plate 3, and the bottom cover 102 are all provided with adapter holes 41. The diameter of the adapter hole 41 is larger than the outer diameter of the drinking pipe 4, so that the lower end of the drinking pipe 4 can pass through the adapter holes 41 on the locking slide plate 2, the linkage slide plate 3, and the bottom cover 102. The locking slide plate 2 and the linkage slide plate 3 can both slide within the action cavity 105, while the drinking pipe 4 passes through the action cavity 105 from the top cover 103 and exits through the bottom cover 102. Therefore, the diameter of the adapter hole 41 needs to be larger than that of the drinking pipe 4 to avoid the drinking pipe 4 affecting the movement of the locking slide plate 2 and the linkage slide plate 3.

[0050] Preferably, this utility model also includes a telescopic straw 42. The upper end of the drinking tube 4 protrudes from the upper surface of the cover 103. The telescopic straw 42 passes through the drinking tube 4, and the lower end of the telescopic straw 42 is fixedly connected to the drinking tube 4, so that the upper end of the telescopic straw 42 can extend out of the upper port of the drinking tube 4. The lower end of the telescopic straw 42 is provided with an extension tube 43. The upper end of the telescopic straw 42 extending out of the drinking tube 4 makes it convenient for the user to suck water. Especially in a car environment, when the user cannot lift the cup to drink water (which would affect the view), the telescopic straw 42 can make it convenient for the user to drink water. Furthermore, when the flip cover 1 is fastened on the cover body 100, the upper end of the telescopic straw 42 can deform and be stored in the drinking tube 4, so that the height of the flip cover 1 protruding from the cover body 100 is less, reducing the overall height of the cup lid.

[0051] Furthermore, a sealing cap is provided on the inner wall of the flip cover 1 (the side opposite to the upper end of the drinking pipe 4) to seal the upper end of the drinking pipe 4 and prevent water from leaking from the drinking pipe 4.

[0052] like Figure 1-2As shown, a large-capacity water cup that can be operated with one hand includes a cup body 44 and a cup lid. A handle 45 is provided on the outer wall of the cup body 44. A bottom cover 102 is detachably mounted on the rim of the cup body 44, with a push-button switch 101 positioned directly opposite the handle 45. The bottom cover 102 can be screwed onto the rim of the cup body 44, and a sealing ring is provided between the bottom cover 102 and the cup body 44. The screwing angle of the bottom cover 102 can be controlled so that the push-button switch 101 faces the handle 45. Users can easily grip the handle 45 to hold the cup and then press the push-button switch 101 with ease, making operation convenient.

[0053] Preferably, when the large-capacity water cup is used in some in-vehicle environments, the bottom of the cup body 44 can be reduced to fit the water cup placement slot in the vehicle.

[0054] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
