[0037] Please refer to Figures 1 to 6 , a flip cup cover with a rear knob in the figure, which mainly designs three components: the flip cover 1, the switch assembly 2, and the cover body 3. The cup cover as a whole can be used as the top sealing component of a thermos cup or the like. The present case mainly optimizes the above three components, especially optimizing the switch assembly 2, which uses the knob 21 built-in the flip cover 1, and uses it in combination with the connecting rod 22 and the lock head 25, so as to quickly open the flip cover 1. In actual application, the shape of the above components and the structure of mutual cooperation can be further optimized.

[0038] The flip cover 1 in the figure is arranged at the upper position of the cover body 3. The flip cover 1 at the end position of one end is realized with the cover body 3 through the torsional spring 4 and the conventional shaft connecting component, so as to facilitate the exposure of the water outlet spout or the automatic buckling of the flip cover 1 and the cover body 3. The flip cover 1 is designed with the cavity structure of the pull groove 12 structure at the position of accommodating the knob 21 of the switch assembly 2. The space of the pull groove 12 needs to meet the flexible pulling of the knob 21. The mouth groove 13 is designed at the position of accommodating the water outlet spout, so as to cover the water outlet spout 4 of the cup cover. The lock buckle 11 and the buckle groove 14 are respectively designed at the position matched with the lock hook 251 of the lock head 25 of the switch assembly 2. The above buckle groove 14 is above the lock buckle 11. The lock hook 251 of the lock head 25 hooks the buckle groove 14 to realize the buckling of the lock head 25 and the flip cover 1 in the initial state, and to protect the sealing state of the water outlet spout. In actual application, local details can be further optimized, such as the additional design of the empty groove structure for the convenience of placing the torsional spring. The flip cover 1 can also be connected with the cover body 3 in other ways.

[0039] The switch assembly 2 in the figure mainly consists of components such as a lever 21, a connecting rod 22, a lock head 25, a connecting rod spring 24, and a lock head spring 26. When the lever 21 is turned, it can drive the connecting rod 22 and the lock head 25 to move respectively, thereby enabling the lock head 25 to hook or unhook the upper flip cover 1.

[0040] The lever 21 in the figure has a structure similar to a paddle. For ease of operation, its body features a rounded arc design. This body maintains a certain clearance with the cover body 3, forming a movable hole 33 to ensure the lever 21's movement. To facilitate hinge connection with the cover body 3, pivots 211 are designed on both sides near the center, positioned above the connecting rod 22. Under external force, when the lever 21 rotates, it drives the connecting rod 22. To facilitate lateral movement of the connecting rod 22, a slotted structure is designed at the bottom near the center. The connecting rod 22 extends towards the lever 21 at the corresponding position, forming an extension 223 with a hole. The lever 21 also has a hole at its bottom. A pin 23 is then inserted to allow the lever 21 to drive the connecting rod 22.

[0041] In the diagram, the connecting rod 22 is positioned between the lever 21 and the lock head 25, serving as a connection and linkage mechanism. The connecting rod 22 has a hollow structure in the middle, forming a limiting hole 222. This creates a limiting relationship with the limiting part 32 at the corresponding position of the cover body 3, ensuring that when the connecting rod 22 is driven by the lever 21, its movement path is consistent with the designed path. For assembly with the lock head 25, insertion holes 221 are designed at both ends of the tail, allowing for assembly with the fixing buckle 252 at the corresponding position of the lock head 25. To ensure the resetting of the connecting rod 22, spring fixing parts 27 can be designed at both ends of the tail of the connecting rod 22. A connecting rod spring 24 is fitted onto each spring fixing part 27. The connecting rod spring 24 drives the automatic resetting of the connecting rod 22. One end of the connecting spring 24 presses against the spring fixing part 27, and the other end presses against the spring pressing part 31 at the corresponding position of the cover body 3.

[0042] The lock head 25 in the figure is assembled with the connecting rod 22 using a fastening method such as a fixing buckle 252. A locking hook 251 is designed in the opposite direction to the fixing buckle 252. This lock head 25 hooks onto the latch groove 14 of the upper flip cover 1 and is fixed to the latch 11. To facilitate the reset of the lock head 25, a lock head spring 26 can be installed at each end between the lock head 25 and the tail of the connecting rod 22. The lock head spring 26 drives the locking hook 251 on the lock head 25 to cooperate with the locking groove of the upper flip cover 1. The connecting rod 22 and the lock head 25 have cross-shaped spring fixing parts 27 at corresponding positions, allowing the lock head spring 26 to be installed on these spring fixing parts 27. The spring fixing parts 27 extend outwards, effectively securing the corresponding springs.

[0043] The cover body 3 in the figure has an outlet hole 34 designed at the water outlet 4 position. The cover body 3 is mainly used to fix the switch assembly 2 and the flip cover 1.

[0044] As shown in the figure, when it is necessary to open the upper cover 1, press the lever 21 inward with your finger. The lever 21 drives the connecting rod 22 to move in the direction of the lever 21. At this time, the connecting rod spring 24 is in a compressed state, and the locking hook 251 disengages from the locking buckle 11, and the upper cover 1 automatically pops open. After releasing your finger, the connecting rod spring 24 extends, thereby driving the connecting rod 22, the locking head 25, and the lever 21 to automatically return to their original positions. When it is necessary to close the upper cover 1, press your finger on the upper cover 1, and the locking buckle 11 of the upper cover 1 locks with the locking hook 251 of the locking head 25.
