The push post 211 passes through the inner cover component 22 and cooperates with the lower end of the fixing component 24. When the cup lid body 2 is in the locked state, the push post 211 pushes the fixing component 24 downward to cooperate and fix it with the inner wall of the cup mouth of the container body 1. When the cup lid body 2 is in the unlocked state, the push post 211 releases the fixing component 24 upward, so that the fixing component 24 disengages from the inner wall of the cup mouth of the container body 1.

[0033] Preferably, the inner sidewall of the outer cover 21 is provided with a limiting step 212, and a limiting groove 2121 is provided on the limiting step 212. The lower end of the rotating cover 232 is provided with a limiting block 2321, and the limiting block 2321 cooperates with the limiting groove 2121 to limit the movement.

[0034] Preferably, the inner cover assembly 22 includes a first inner cover 222 and a second inner cover 223. The first inner cover 222 is provided with a limiting hole 2221, and the second inner cover 223 is provided with a limiting post 2231. The first inner cover 222 and the second inner cover 223 are detachably connected to the limiting hole 2221 through the limiting post 2231. The first inner cover 222 and the second inner cover 223 cooperate to form the rotation space 221.

[0035] Preferably, the inner cover assembly 22 further includes a first return spring 224, the first inner cover 222 is provided with a first fixing post 2222, the rotating post 231 is provided with a second fixing post 2311, one end of the first return spring 224 is connected to the first fixing post 2222, and the other end of the first return spring 224 is connected to the second fixing post 2311.

[0036] Preferably, the system also includes an exhaust assembly 3, which includes an exhaust top plate 31, an exhaust valve 32, a second return spring 33, and a fixed umbrella 34. The rotating column 231 and the rotating cover 232 are respectively provided with a first exhaust hole 2313 and a second exhaust hole 2324. The exhaust valve 32 is installed in the first exhaust hole 2313. The exhaust top plate 31 is disposed at the upper end of the exhaust valve 32 and located in the second exhaust hole 2324. The fixed umbrella 34 is disposed at the lower end of the inner cover assembly 22. The lower end of the exhaust valve 32 extends out of the fixed umbrella 34. The second return spring 33 is disposed between the fixed umbrella 34 and the exhaust valve 32.

[0037] Preferably, the fixing component 24 includes a movable ring 241 and a spring-loaded member 242, the upper end of which engages with the movable ring 241, and the lower end of which is connected to the fixing umbrella 34.

[0038] Preferably, both the first inner cover 222 and the second inner cover 223 are provided with through holes 4, the upper end of the push post 211 is connected to the lower end of the limiting step 212, and the lower end of the push post 211 passes through the through hole 4 and engages with the upper end of the movable ring 241.

[0040] Specifically, when the cup lid body 2 needs to be locked, the outer cover 21 is first pressed down to make the rotating cover 232 disengage the limiting block 2321 from the limiting groove 2121 of the limiting step 212. The rotating cover 232 will rotate and reset under the drive of the first reset spring 224. When the outer cover 21 is pressed down, the pushing column 211 will push the movable ring 241 downward, causing the spring member 242 to be compressed downward, thereby making the spring member 242 cooperate and fix with the inner wall of the cup mouth of the container body 1. At this time, the cup lid body 2 is in a locked state.

[0041] When the cup lid body 2 needs to be unlocked, first rotate the rotating cover 232 to align the limiting block 2321 with the limiting groove 2121 of the limiting step 212. Then, pull the outer cover 21 upward to engage the limiting block 2321 of the rotating cover 232 with the limiting groove 2121. At this time, the first return spring 224 is in a tensioned state. At this time, the outer cover 21 will move upward relative to the rotating cover 232. When the outer cover 21 moves upward, the pushing column 211 disengages from the movable ring 241, thereby relaxing the spring member 242 and disengaging it from the inner wall of the cup mouth of the container body 1. At this time, the cup lid body 2 is in an unlocked state.

[0042] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included within the scope of the present invention.
