Description

Technical Field

[0001] The present invention relates to the technical field of drinking utensils, in particular to a water cup flip cover and a water cup provided with the water cup flip cover. Background Art

[0002] Generally, the flip cover of a water cup is provided with components such as a flip cover, a connector, and a switch button. Since the switch button is provided separately and assembled on the cup cover by pins, the button protrudes from the cup cover, resulting in an incomplete appearance of the cup cover, a complicated structure, and inconvenient assembly and production.

[0003] In this regard, CN210158427U discloses a rotating bouncing cup cover, which includes a main body connected to the cup body, a spring cover, a drinking port, a screw cover and a cleaning cover. The main body is provided with a drinking port, and the right side of the spring cover can be flipped and hinged with the right side of the main body through a torsion spring and a locating pin. A sealing ring seat is provided at the bottom of the spring cover, and a sealing cap is provided on the sealing ring seat. The sealing cap is sealed and connected to the drinking port. The screw cover is rotatably mounted on the spring cover, and the cleaning cover is detachably mounted on the screw cover. When the spring cover and the main body are in a closed state, the hook portion of each hook is hung together with the barb hook on the corresponding side. When opening, the screw cover is rotated counterclockwise, and the hook on the screw cover is also displaced counterclockwise, so that the hook is separated from the corresponding barb on the main body, and the spring cover pops open under the action of the torsion spring.

[0004] Although this rotating bouncing cup cover is beautiful in appearance, easy to operate and safer, it has many parts and an overly complicated structure. Moreover, since a rubber sleeve is used to drive the cup cover to rotate and reset, there are certain deficiencies in both the operating feel and the performance. After long-term use, once the rubber sleeve ages and loses its elasticity, the cup cover cannot be automatically reset normally, and manual auxiliary actions are required to reset it, which greatly affects the user experience. Summary of the invention

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0033] Please refer to Figures 1 to 4 , Figure 1 A top view of a water cup flip cover disclosed in an embodiment of the present invention; Figure 2 for Figure 1 AA view; Figure 3 for Figure 1 A side view of the water cup flap shown; Figure 4 for Figure 3 BB view.

[0034] In one embodiment, the water cup elastic cover 1 provided by the present invention is mainly composed of two major parts: a connecting body 2 and a flip cover 3. The flip cover 3 is rotatably connected to the connecting body 2 and can be opened or closed relative to the connecting body 2. The flip cover 3 is further composed of an outer cover 4 and an inner cover 5. The outer cover 4 can rotate relative to the inner cover 5, and the flip cover 3 can be controlled to open by rotating the outer cover 4.

[0035] The flip cover 3 is rotatably connected to the connecting body 2 via the inner cover 5 at one side via a rotating shaft 6. A first torsion spring 7 is provided at the rotating connection between the inner cover 5 and the connecting body 2 so that the flip cover 3 can automatically pop open after being unlocked.

[0036] The outer cover 4 and the inner cover 5 are rotated and matched in a mutually nested manner, and a second torsion spring 8 is provided at a central position between the outer cover 4 and the inner cover 5 to drive the outer cover 4 to reset after rotating relative to the inner cover 5; the inner cover 5 is provided with a first groove 9 at a central position on the top for accommodating the second torsion spring 8, and the outer cover 4 is provided with a second groove 10 at a central position for accommodating the second torsion spring 8, a part of the second torsion spring 8 is located in the first groove 9, and the other part is located in the second groove 10.

[0037] In order to facilitate the assembly of the second torsion spring 8, the second groove 10 is passed through from top to bottom, and a top cover 11 is provided on the outer cover 4. After the second torsion spring 8 is assembled in place, the top cover 11 is fixed to the outer cover 4 to limit the upward movement of the second torsion spring 8. The inner circumferential wall of the top cover 11 and the corresponding outer circumferential wall of the outer cover 4 can be interference fit to prevent the top cover 11 from falling off.

[0038] Of course, the top cover 11 and the outer cover 4 can also be connected by snapping. Moreover, as another embodiment, the top cover 11 can also be designed to be relatively small, only covering the upper area of ​​the second groove 10, and then connected to the outer cover 4 by interference fit or snapping.

[0039] The first groove 9 on the inner cover 5 has a torsion spring arm groove 12 extending in the tangential direction to accommodate the arm of the second torsion spring 8 located at the bottom. The second groove 10 on the outer cover 4 has two torsion spring arm grooves 12 extending in the tangential direction. The two torsion spring arm grooves 12 are in a "V" shape of about 90°. The projection of one torsion spring arm groove 12 coincides with the torsion spring arm groove 12 on the inner cover, and the other torsion spring arm groove 12 is used to accommodate the arm of the second torsion spring 8 located at the top. In the actual assembly process, the outer cover 4 can be first installed on the inner cover 5, and then the second torsion spring 8 can be inserted from the top of the outer cover 4, and then the arm of the second torsion spring 8 located at the top can be twisted to pre-deform it, and then it can be stuck in the corresponding torsion spring arm groove 12 on the outer cover 4 to complete the installation of the second torsion spring 8.

[0040] The outer cover 4 and the connector 2 are provided with a matching hook 13 and a hook 14 at the front, that is, on the other side relative to the rotating shaft 6. The hook 13 and the hook 14 can be disengaged from each other when the outer cover 4 rotates relative to the inner cover 5 to exceed a set angle, and can be locked with each other after the outer cover 4 is reset relative to the inner cover 5. The closing and opening of the flip cover 3 are achieved by locking and disengaging between the hook 13 and the hook 14.

[0041] Please refer to Figure 5 , Figure 5 for Figure 1 Schematic diagram of the exploded structure of the water cup cover shown.

[0042] As shown in the figure, the head of the hook 13 of the connecting body 2 has a first inclined surface 15, and the head of the hook 14 of the outer cover 4 has a second inclined surface 16 corresponding to the first inclined surface 15. In this way, when closing the flip cover 3, the first inclined surface 15 and the second inclined surface 16 are contacted and matched to drive the outer cover 4 to rotate a certain angle relative to the inner cover 5, and then the second torsion spring 8 drives the outer cover 4 to reset, so that the hook 13 and the hook 14 are locked with each other. Therefore, the flip cover 3 can be automatically closed and locked by just pressing the flip cover 3, making it more convenient to close the flip cover 3.

[0043] In addition, in order to prevent the outer cover 4 and the inner cover 5 from detaching from each other, the outer cover 4 and the inner cover 5 can be connected by a snap buckle. At the same time, in order to enable the outer cover 4 to rotate more smoothly, arc-shaped convex ribs 17 can be distributed at intervals along the circumferential direction on the top of the inner cover 5, circumferential convex ribs 18 are provided on the outer periphery of the inner cover 5, and vertical convex ribs 19 are provided at intervals on the outer periphery of the inner cover 19 near the top. The arc-shaped convex ribs 17, the circumferential convex ribs 18, and the vertical convex ribs 19 can be integrally formed with the inner cover 5. The outer periphery of the inner cover 5 has a step portion, the circumferential convex ribs 18 are located in the area below the step portion, and the vertical convex ribs 19 are located in the area above the step portion, and are relatively short in length.

[0044] Please refer to Figure 6 , Figure 7 , Figure 6 It is a side view when the flip cover is in the open state; Figure 7 for Figure 6 CC view of the .

[0045] When in use, the outer cover 4 is rotated by hand at a very small angle, the hook 14 on the outer cover 4 is disengaged from the hook 13 on the connector 2, the flap 3 is released from restriction, and the flap 3 as a whole is flipped open around the rotating shaft 6 under the torsion of the first torsion spring 7, and at the same time, the outer cover 5 is reset relative to the inner cover 5 under the action of the second torsion spring 8 (the reset at this time is a reset to a non-closed state).

[0046] When closing the cover, the flip cover 3 is pressed by hand, and the flip cover 3 as a whole flips over around the rotating shaft 6, so that the hook 14 of the outer cover 4 squeezes the hook 13 of the connecting body 2 through the mutually matched inclined surfaces, thereby forcing the outer cover 4 to rotate a certain angle relative to the inner cover 5, and the second torsion spring 8 is twisted until the flip cover 3 is completely closed, the hook 13 and the hook 14 are staggered from each other, the squeezing of the hook 14 is released, and the outer cover 4 is reset relative to the inner cover 5 under the action of the rebound force of the second torsion spring 8, the hook 13 and the hook 14 are engaged with each other, and the flip cover 3 is locked.

[0047] It can be seen that when opening the flip cover 3, it is only necessary to rotate the outer cover 4. There are two ways to close the flip cover 3. One is to directly press down the flip cover 3. Under the action of the downward pressure, the inclined surface of the hook is used to decompose the downward pressure into a driving force for circumferential rotation, so that the outer cover 4 rotates counterclockwise (or clockwise). When the contact area of ​​the inclined surface of the hook gradually decreases until there is no contact, the outer cover 4 rotates clockwise (or counterclockwise) again under the elastic force of the second torsion spring 8, and the flip cover 3 is locked. The other is to manually rotate the outer cover 4 counterclockwise (or clockwise) first to make the two hooks avoid each other. After closing the flip cover 3, the outer cover 4 can continue to rotate clockwise (or counterclockwise) manually or driven by the second torsion spring 8, and the flip cover 3 is locked.

[0048] The above embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the hooks that cooperate with the outer cover 4 and the connector 5 are divided into two groups, which are respectively arranged on the left and right sides; or the top cover 11 is not arranged on the outer cover 4, and other methods are used to limit the second torsion spring 8, etc. Since there are many possible implementation methods, they will not be described one by one here.

[0049] The cup flip cover 1 can control the opening of the flip cover by rotating the outer cover 4 of the flip cover 3. When the flip cover 3 is in the closed state, the second torsion spring 8 can make the outer cover 4 and the hook of the connector 2 tightly bite and not loosen. In the process of closing the flip cover 3, the second torsion spring 8 can drive the outer cover 4 to reset relative to the inner cover 5 after rotation, so that the hooks are locked with each other. By rotating the flip cover outer cover 4, the traditional switch button is replaced, so that the button and the cup cover are integrated, thereby achieving the effect of eliminating the switch button in appearance, the appearance is more simple and overall, the lid opening method is more convenient, and the number of parts is small, the structure is simple, the performance is stable, and it can provide consumers with a good operating feel and use experience.

[0050] In addition to the above-mentioned water cup flip cover, the present invention also provides a water cup, including a cup body and a cup cover arranged on the cup body, the cup cover is the water cup flip cover 1 described above, and the water cup flip cover 1 is installed at the cup mouth of the cup body through a connector 2. Regarding other structures of the water cup, please refer to the prior art, which will not be repeated in this article.

[0051] The above is a detailed introduction to the water cup cover and water cup provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
