DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.
[0021] Embodiment one: Please refer to Figures 1-5 The application discloses a flip cover cup cover, which comprises: A cover body 1, which is provided with a water outlet 11 for drinking water. The water sealing piece 2 is located on the inner side of the cover body 1 and seals the water outlet 11 by moving up and down; The connecting column 3 is connected with the water sealing piece 2 at one end and passes through the cover body 1 to the outer side of the cover body 1 at the other end. A through hole 12 is formed on the cover body 1 at a position corresponding to the connecting column 3, so that the connecting column 3 passes through the through hole 12 and is guided by the through hole 12. The flip cover 4 is located on the outer side of the cover body 1 and is rotationally connected with the connecting column 3 at one end. The flip cover 4 can rotate between a first rotation position and a second rotation position. The flip cover 4 has a cam 41 at a position corresponding to the connecting column 3. The cam 41 is in sliding contact with the top surface of the cover body 1. The cam 41 rotates together with the flip cover 4. When the flip cover 4 rotates to the first rotation position, the connecting column 3 moves upward under the action of the cam 41 and moves the water sealing piece 2 to a water sealing position to seal the water outlet 11. When the flip cover 4 rotates to the second rotation position, the connecting column 3 can move downward to unseal the water outlet 11. The elastic member 5 is arranged between the water sealing piece 2 and the cover body 1 and is used to push the water sealing piece 2 to move downward when the flip cover 4 rotates to the second rotation position.
[0022] In a specific implementation, the connecting column 3 is guided and limited by the through hole 12, so that the water sealing piece 2 and the flip cover 4 cannot move left, right, forward or backward on the cover body 1. When the flip cover 4 is rotated (at this time, the flip cover 4 acts as a lever), the cam 41 rotates together, thereby driving the connecting column 3 and the water sealing piece 2 to move up and down to seal the water outlet 11. Since the water sealing piece 2 is located on the inner side of the cover body 1, it is not easy to be pushed open by the air pressure inside the cup body 6. When the cup body 6 has a negative pressure, it is relatively easy to open.
[0023] Since the water sealing piece 2, the connecting column 3 and the flip cover 4 are not provided with a pin shaft and a pin hole or an attachment member, only a through hole 12 is formed on the cover body 1 to pass through the connecting column 3, so that the flip cover 4 can be assembled with the cover body 1, the structure is simpler, the assembly is more convenient, the structural reliability is stronger, the cover body 1 is convenient to produce by opening a mold, and the production cost is greatly reduced.
[0024] It should be noted that the flip cover 4 cannot be rotationally connected with the cover body 1 by a connecting shaft. Since the cam 41 is used, the height of the rotation center of the flip cover 4 is not fixed, so the flip cover 4 cannot be rotationally connected with the cover body 1 by a connecting shaft, and it is unnecessary to be rotationally connected with the cover body 1.
[0025] Preferably, the connecting column 3 is fixedly connected with the water sealing piece 2 (such as the structure shown in the accompanying drawings). Figure 4 Preferably, the elastic member 5 is a spring. Preferably, the elastic member 5 is a spring.
[0026] In an embodiment, when the cover 4 is turned to the first turning position, one end of the cover 4 can cover the water outlet 11, and when the cover 4 is turned to the second turning position, the cover 4 can expose the water outlet 11. In this way, dust can be prevented from falling into the water outlet 11 in a non-drinking state.
[0027] In an embodiment, as shown in the accompanying drawings, the outer surface of the cam 41 is divided into a pushing section 411 and a rest section 412, and the top end 413 of the cam 41 (i.e. the farthest point of the cam 41 from the center of rotation of the cam 41) is located between the pushing section 411 and the rest section 412. When the cover 4 is turned to the first turning position, the top end 413 is located on the rear side of the center of rotation of the cam 41. Figure 5 In a specific implementation, since the top end 413 is located on the rear side of the center of rotation of the cam 41, when an external force accidentally touches the cover 4, the cover 4 is not easily opened, and even if the cover 4 is lifted by an angle, as long as the top end 413 is located on the rear side of the center of rotation of the cam 41, the cover 4 will automatically rotate back under the pushing force of the elastic member 5, ensuring that the cover 4 cannot be easily opened by accidental touch.
[0028] In an embodiment, the rest section 412 is a flat surface, which is in contact with the top surface of the cover body 1 to prevent the cam 41 from continuing to rotate in the corresponding direction.
[0029] In an embodiment, when the cover 4 is in the first turning position, the end of the cover 4 is placed on the top of the cover body 1 to jointly prevent the cam 41 from continuing to rotate in the corresponding direction with the rest section 412. It should be noted that since the cover 4 is usually made of plastic, if the cover 4 alone is used to prevent the cam 41 from continuing to rotate without the assistance of the rest section 412, the cover 4 will easily deform over time, which will reduce the water sealing performance. Similarly, if the rest section 412 alone is used, stress concentration will also easily occur (in order to be aesthetically pleasing, the cam 41 cannot be made too large, and therefore stress concentration will easily occur at the rest section 412), and the rest section 412 will also deform over time. The joint action of the rest section 412 and the cover 4 can prolong the service life and ensure the long-term sealing performance of the cup cover.
[0030] In an embodiment, the bottom of the cover body 1 is provided with an annular chamber 13 corresponding to the position of the water outlet 11, the bottom of the annular chamber 13 is open, the water sealing piece 2 is located below the annular chamber 13, and the water sealing piece 2 is provided with a flexible sealing gasket 21 around the water sealing piece 2 for sealing cooperation with the annular chamber 13.
[0031]
[0032] It should be noted that the elastic sealing gasket 21 has a certain elastic deformation amount, which can maintain the sealing state when the rest section 412 of the cam 41 contacts the top surface of the cover body 1, and has a certain compression allowance for the compression of the top tip 413 when it contacts the top surface of the cover body 1.
[0033] In an embodiment, the flip cover 4 is provided with a rotating shaft 42 at one end of the connecting column 3, the connecting column 3 is provided with a rotating groove 31 at the position of the rotating shaft 42, the rotating groove 31 is obliquely arranged, one end of the rotating groove 31 penetrates one side of the connecting column 3 (specifically, one side of the connecting column 3 corresponding to the water outlet 11), and the other end is obliquely upwardly connected with the rotating shaft 42. The rotating groove 31 has a neck portion 311, the distance between the neck portion 311 is less than the diameter of the corresponding rotating shaft 42, and when the rotating shaft 42 moves outward along the rotating groove 31 and separates from the connecting column 3, the neck portion 311 can be deformed by extrusion, and the rotating shaft 42 can pass through the neck portion 311.
[0034] In a specific implementation, since the rotating groove 31 is obliquely arranged and the obliquely upward end is connected with the rotating shaft 42, when the user flips the flip cover 4, the rotating shaft 42 is subjected to an upward force under the action of the cam 41, and therefore, the rotating shaft 42 is not easily separated from the rotating groove 31. The arrangement of the neck portion 311 further ensures that even under abnormal conditions, the flip cover 4 is not easily separated from the rotating groove 31.
[0035] In an embodiment, the flip cover 4 is provided with a limiting clamping point 43 on both sides, and the cover body 1 is provided with a limiting clamping groove 14 matched with the limiting clamping point 43, and the flip cover 4 can be clamped by the corresponding limiting clamping groove 14 when the flip cover 4 is rotated to the first rotating position and the second rotating position. In this way, when drinking, the flip cover 4 is rotated to the second rotating position, and at this time, the limiting clamping point 43 is clamped with the limiting clamping groove 14, which prevents the flip cover 4 from rotating, thereby facilitating water drinking. When not drinking water, the flip cover 4 is rotated to the first rotating position, and at this time, the limiting clamping point 43 is clamped with the limiting clamping groove 14, which will produce a feeling of jerk or a "click" sound, thereby informing the user that the limiting clamping point 43 has been clamped in place, thereby improving the user experience.
[0036] Embodiment Two: The difference between this embodiment and the first embodiment is only that the connecting column 3 and the water sealing piece 2 are connected in different ways, specifically: The connecting column 3 is rotationally connected with the water sealing sheet 2 (not shown in the figure), and when the connecting column 3 is rotationally connected with the water sealing sheet 2, the connecting column 3 is located at the center of the water sealing sheet 2, and a torsion spring is arranged between the connecting column 3 and the water sealing sheet 2, and the initial posture of the water sealing sheet 2 is maintained in a horizontal posture (approximately horizontal) or a posture parallel to the bottom of the cover body 1 (approximately parallel) by the torsion spring. In this way, when the bottom plane of the cover body 1 is inclined (affected by machining errors, or affected by modeling design, or affected by other factors so that the plane of the bottom of the cover body 1 is inclined), the rotating water sealing sheet 2 can automatically fit the bottom plane of the cover body 1, thereby achieving better water sealing.
[0037] Embodiment three: Referring to Figure 6 The embodiment provides a water cup, which comprises a cup body 6, and the cup body 6 is provided with the flip type cup cover in the above-mentioned embodiment one or embodiment two.
[0038] It should be noted that the bottom of the cover body 1 of the flip type cup cover is provided with external threads, the mouth of the cup body 6 is provided with internal threads matched with the external threads, and the cup body 6 and the cup cover are connected in a threaded matching mode. Of course, the bottom of the cover body 1 can also be provided with internal threads, and the mouth of the cup body 6 is provided with external threads. Of course, other existing modes can also be used to connect the cup body 6 and the cup cover.
[0039] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition and the like between the components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.
[0040] In addition, if the embodiments of the present application involve descriptions such as "first", "second" and the like, the descriptions of "first", "second" and the like are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of the various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope of the present application.
[0041] In addition, "a plurality of" means two or more.
[0042] The above only describes the preferred embodiments of the present application and does not limit the present application, and any modification, equivalent replacement, improvement and the like made within the spirit and principles of the present application shall be included in the protection scope of the present application.
