The clamping groove 203 is formed on the outer wall of the bottom cover 2, and more specifically, one end of the clamping groove 203 is in communication with the external space. The clamping hook 302 is formed on the inner wall of the sliding cover 3b corresponding to the clamping groove 203. In this way, when the sliding cover 3b moves, the clamping hook 302 can move along the clamping groove 203 synchronously until it moves into the external space or moves back into the clamping groove 203. When the clamping hook 302 is latched in the clamping groove 203, the clamping hook 302 will be limited by the upper and lower inner walls of the clamping groove 203, thereby limiting the up-down flipping of the sliding cover 3b and the base 3a, and keeping the entire flip cover assembly 3 and the bottom cover 2 in continuous and stable latching.

[0040] Further, the locking structure a1 has two groups, and the locking structure a1 is located on the left and right sides of the bottom cover 2 and the sliding cover 3b, respectively. Therefore, when the flip cover assembly 3 is latched with the bottom cover 2, by increasing the number of locking structures a1, the fixing points between the sliding cover 3b and the bottom cover 2 are correspondingly increased. At the same time, the locking structures a1 are evenly distributed between the sliding cover 3b and the bottom cover 2, which ensures that the two groups of clamping hooks 302 and clamping grooves 203 are latched to realize more stable connection between the flip cover assembly 3 and the bottom cover 2.

[0041] As shown in Figures 6 to 8 The bottom of the base 3a is formed with two protrusions 303, and the two protrusions 303 are kept apart.

The tea leakage hole 502 has a plurality of tea leakage holes 502 arranged around the straw hole 501501. The tea leakage hole 502 is used to isolate the tea leaves in the cup body 1. The straw 6 is inserted into the tea bin 5 through the straw hole 501501. In this way, the straw 6 can be limited by the tea bin 5 and kept in a specific position in the cup body 1, avoiding shaking and sinking. The lower end of the straw 6 extends into the cup body 1, and the upper end extends to the top of the cup body 1. In this way, the user can use the straw 6 to drink the beverage in the cup body 1. The bottom cover 2 is sleeved on the tea bin 5 and can be detachably fixed with the tea bin 5. In the fixed state, the tea bin 5 is completely closed. If the water outlet 201 on the bottom cover 2 is opened at this time, the beverage in the cup body 1 will first pass through the tea leakage hole 502 and then flow from the water outlet 201 to the user's mouth. In this way, it is ensured that the beverage can be directly drunk.

[0047] As Figures 9 to 11 shown, it further comprises a limiting silica gel piece 7. The limiting silica gel piece 7 is inserted into the straw hole 501501. The inner wall of the straw hole 501501 is formed with a support block 501a. The number of support blocks 501a is not particularly limited. The support blocks 501a are kept apart. The outer wall of the limiting silica gel piece 7 is formed with a support groove 701. The support groove 701 corresponds to the support block 501a one by one. The support block 501a is embedded in the support groove 701. In this way, the limiting silica gel piece 7 can be stably kept in the straw hole 501501, thereby preventing it from moving up and down. The limiting silica gel piece 7 is further provided with a cross limiting groove 702. The straw 6 is inserted into the cross limiting groove 702. That is to say, the straw 6 and the tea bin 5 are indirectly matched. The straw 6 is still kept in the straw hole 501501 relative to the tea bin 5. Since the silica gel has good elasticity, when the straw 6 is inserted into the cross limiting groove 702, the cross limiting groove 702 will deform, thereby tightly fitting on the outer wall of the straw 6, so that the straw 6 can be stably fixed, effectively reducing the possibility of moving up and down and swinging, and ensuring smooth drinking.
