[0016] The present invention will be further described below with reference to specific embodiments.

[0017] like Figure 1-4 As shown, an automatic pop-up cup cover comprises a base 1, an end cover 2 arranged on the base 1, and an exhaust assembly 3 arranged between the end cover 2 and the base 1. The side wall of the base 1 is provided with two corresponding slots 4, and a fastener 5 that is engaged with the cup body is provided in the slot 4. A pressing portion 6 is formed on the upper end of the fastener 5, and the pressing portion 6 is arranged in an opening 7 opened in the side wall of the end cover 2. A pop-up member 8 is sleeved on the fastener 5, and a plurality of protrusions 9 are formed on the inner wall of the upper end of the pop-up member 8. A spring 10 is provided on the protrusion 9, and the other end of the spring 10 abuts against the lower end surface of the end cover 2. The protrusion 9 is arranged in a limiting groove 11 opened on the outer wall of the base 1.

[0018] The automatic pop-up cup lid of this technical solution is provided with a pop-up member 8 so that the cup lid can be automatically popped out when the user presses the fasteners 5 on both sides. The user can then release the fasteners 5 to take out the cup lid. There is no need to press the fasteners 5 while taking out the cup lid, which is very labor-saving and greatly improves the user experience. The above-mentioned protrusion 9 is provided with a protrusion for fixing the spring 10.

[0019] Preferably, the spring 10 is inserted into a through hole 12 provided on the base 1. Inserting the spring 10 into the through hole 12 can increase the stability of the spring 10 and increase its service life.

[0020] Preferably, the lower end surface of the end cover 2 is formed with a plurality of spring fixing seats 13 corresponding to the spring 10. The provision of the spring fixing seats 13 can better fix the spring, prevent the spring 10 from being displaced during use, and increase its service life.

[0021] Preferably, the upper outer wall of the pop-up member 8 is formed with an extension portion 30 that abuts against the cup rim. When the cup lid is closed, the user presses the cup lid to move the pop-up member upward until the outer wall of the lower end of the latch is snapped out and the latch is snapped into engagement with the cup body. At this time, the cup lid and the cup body are in the closed state.

[0022] Preferably, the exhaust assembly 3 includes a movable shaft 14, the upper end of the movable shaft 14 is arranged in a limit seat 15 formed on the lower end surface of the end cover 2, and the lower end of the movable shaft 14 is arranged in a limit seat 2 16, and an annular protrusion 17 is formed on the movable shaft 14, and an inclined surface 18 is formed on the upper end of the outer wall of the annular protrusion 17, and the inclined surface 18 is adapted to the inclined sliding portion 19 formed on the inner wall of the snap member 5; an inner ring protrusion 20 is formed on the inner wall of the limit seat 2 16, and the inner ring protrusion 20 divides the limit seat 2 16 into an upper part 21 and a lower part 22, and the upper part 21 is provided with a spring 23, and the upper end surface of the spring 23 abuts against the lower end surface of the annular protrusion 17.

[0023] Preferably, an annular groove 24 is formed at the lower end of the movable shaft 14 , and a sealing ring 25 is sleeved on the annular groove 24 , and the outer wall of the sealing ring 25 abuts against the inner wall of the lower portion 22 .

[0024] Preferably, a sliding limit block 26 is formed on the lower end surface of the fastener 5 , and the sliding limit block 26 is adapted to a sliding limit groove 27 provided in the base 1 .

[0025] Working principle: When the user puts on the cup lid, he needs to put the cup lid on the cup and press it downwards. At this time, the extension part 30 on the pop-up part abuts against the cup mouth. When the cup lid is put on, the user presses the cup lid to move the pop-up part upwards until the buckle 31 on the outer wall of the lower end of the buckle 5 pops out, and the buckle 31 is engaged with the cup body. The upper end surface of the buckle 31 abuts against the lower end surface of the pop-up part 8. At this time, the cup lid and the cup body are in the covered state. When the user needs to open the cup lid, he only needs to press the pressing parts 6 on both sides. At this time, the buckle 31 can retract inward. At this time, the pop-up part 8, because there is no buckle 31 to resist and it bounces down under the action of spring 10, can support the entire end cover 2, achieving the effect of automatic pop-up. At this time, the user releases the pressing part 6 and only needs to take out the end cover 2.

[0026] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
