[0021] To make the technical solution of this utility model clearer, the following description is in conjunction with the appendix. Figures 1 to 5 This specification provides a detailed description of the present invention. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0022] A flip-type cup lid with a knob lock includes a lid body 1, a flip cover 2, and a knob 3. The top of the lid body 1 is recessed with a groove 10. The bottom wall of the groove 10 is provided with a water outlet 11 and a constant pressure hole 12 (for easy drinking; the water outlet 11 for direct drinking is usually located at the edge, while the water outlet 11 for sipping can be located in the middle of the bottom wall of the groove 10). The two side walls of the groove 10 are also provided with locking holes 13. The flip cover 2 is rotatably connected to one end of the groove 10 and is used to open and close the water outlet 11 (in this embodiment, the water outlet 11 for direct drinking is taken as an example; the water outlet 11 for sipping needs to be connected to a sipping nozzle, and the flip cover 2 is used to open and close the sipping nozzle). The knob 3 is rotatably mounted on the flip cover 2. The outer wall of the knob 3 has a knob wall 31 that protrudes radially outward. When the knob 3 is rotated and the knob wall 31 is engaged in the locking hole 13, it is in a locked state; when the knob wall 31 is disengaged from the locking hole 13, it is in an unlocked state.

[0023] Specifically, the flip cover 2 includes, from top to bottom, an upper flip piece 21, a lower flip piece 22, and a sealing element 23; the upper flip piece 21 and the lower flip piece 22 are detachably connected, and in this embodiment, they are fixed with screws (of course, snap-fit ​​connections or other methods can also be used); there is a gap between the upper flip piece 21 and the lower flip piece 22 for the knob wall 31 to move, and openings for the knob wall 31 to extend out are provided on both sides between the upper flip piece 21 and the lower flip piece 22; the top surface of the lower flip piece 22 is provided with a rotating shaft 221, and the knob 3 is rotated and sleeved on the outside of the rotating shaft 221; the upper flip piece 21 is provided with a through hole 211 for the knob 3 to pass through, so that the user can operate the knob 3 to rotate; the sealing element 23 is snapped onto the lower surface of the lower flip piece 22 to seal the water outlet 11 and the constant pressure hole 12.

[0024] Specifically, the top surface of the lower flap 22 has symmetrical raised strips 222 on both sides. When locked, the lower surface of the knob wall 31 abuts and presses against the raised strips 222. This structure has two functions: first, it can be used to further press the flap 2 to prevent water leakage; second, after contact, the knob wall 31 is essentially locked and has a locking function. Furthermore, the raised strips 222 can be made of flexible materials (such as silicone, rubber, TPE, etc.). This material can avoid wear when rubbing against the knob wall 31, and its elasticity can also make the flap 2 be pressed more firmly. Its friction with the knob wall 31 can make the knob 3 better keep in the locked state.

[0025] Specifically, the top surface of the lower flip piece 22 is also provided with a first limiting part 223. When the knob 3 is rotated, at least one knob wall 31 of the knob 3 is abutted and restricted by the first limiting part 223, the knob 3 is rotated to the position and locked. The first limiting part 223 can be used to remind the knob to rotate to the position and also prevent the knob 3 from rotating without restriction, which will improve the user experience.

[0026] Specifically, the top surface of the lower flap 22 is also provided with a second limiting part 224 and a third limiting part 225. The second limiting part 224 and the third limiting part 225 are used to hold the limiting knob wall 31. When the knob 3 is rotated, the knob wall 31 first passes the third limiting part 225 and is then blocked by the second limiting part 224, stopping the rotation. At this time, the knob wall 31 is clamped between the second limiting part 224 and the third limiting part 225, keeping the knob 3 in the unlocked state.

[0027] Specifically, the upper flap 21 has several perforated holes 212 for easy rinsing, and the water after rinsing will not accumulate in the interlayer between the upper flap 21 and the lower flap 22, making it more hygienic.

[0028] Specifically, the constant pressure hole 12 is used to balance the air pressure inside and outside the water cup to ensure smooth water flow. This is existing technology and will not be elaborated here.

[0029] Specifically, the flip cover 2 is rotatably connected to the cover body 1 via a pivot, and the flip cover 2 and the cover body 1 are also connected by a flip elastic element (usually a torsion spring, but silicone rings or other elastic rings can also be used; this is existing technology, mainly to provide flip elastic force for the flip cover 2), so that the flip cover 2 can automatically pop up and flip open in the unlocked state.

[0030] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
