[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-4The utility model provides a cup cover, including cover 1, first outer thread 2 and straw assembly, the lower part outside of cover 1 is provided with first outer thread 2, the center of cover 1 is provided with installation pipe 9, the upper part of installation pipe 9 is provided with bearing 3, the inner ring of bearing 3 is connected with installation pipe 9, the outer ring of bearing 3 is provided with rotary disc 4, rotary disc 4 is arranged above cover 1, the upper part of installation pipe 9 is further provided with close slot, the outer wall of close slot is provided with second outer thread 5, the straw assembly includes connecting seat 10 and straw body 11, and straw body 11 is through with connecting seat 10, the lower part of connecting seat 10 is provided with the screw groove that is connected with second outer thread 5, and the upper and lower sides of straw body 11 and installation pipe 9 are provided with the through -hole of consistent inner diameter, and cover 1 is further provided with air hole 6, air hole 6 is arranged below rotary disc 4, and air hole 6 is arranged on the circumferential side of installation pipe 9.

[0021] The first outer thread 2 arranged on the lower part of the cover 1 is designed to match the thread structure of the common cup mouth. When the cup cover is placed on the cup, by rotating the cover 1, the first outer thread 2 and the inner thread of the cup mouth are engaged with each other. Based on the screw pair principle of thread connection, with rotation, the cover 1 gradually moves downward and closely fits on the cup mouth, forming a reliable sealing connection.

[0022] The installation pipe 9 through the center of the cover 1 provides positioning and support structure for the subsequent installation of the straw assembly, and the air hole 6 is arranged below the rotary disc 4 and on the circumferential side of the installation pipe 9. When the user drinks the beverage through the straw, the air pressure inside the cup will be reduced to form a negative pressure environment. At this time, the external air can enter the cup through the air hole 6. According to the principle of air pressure balance, the air entering supplements the air pressure inside the cup, thereby ensuring the balance of air pressure inside and outside the cup, so that the beverage can flow into the user's oral cavity through the straw, the installation pipe 9 and other channels, realizing a smooth drinking process. Moreover, the relatively concealed position of the air hole 6 does not hinder the overall appearance, and can avoid the direct entry of external pollutants into the cup through the air hole 6, ensuring the combination of function and beauty. The inner wall of the straw body 11 can also be provided with a hose through the through hole for water absorption.

[0023] The inner ring of the bearing 3 is fixedly connected with the installation pipe 9, and the outer ring is connected with the rotary disc 4, which can rotate the rotary disc 4. Like a fingertip top, it provides decompression and interest. The outer side of the rotary disc 4 is provided with a plurality of groups of friction grooves 7 to ensure the stability of driving the rotary disc 4.

[0024] In this embodiment, the rotating disk 4 near the bearing 3 is also provided with several sets of hollow holes 8. From an aesthetic point of view, the unique shape and arrangement of these hollow holes 8 on the rotating disk 4 near the bearing 3 break the original monotonous appearance of the rotating disk 4, forming a layered and artistic shape that meets people's aesthetic needs for the exquisite and unique appearance of products, making the entire cup lid more visually attractive. From a functional point of view, the hollowed-out parts remove a portion of the material from the rotating disk 4.

[0025] Erasable markers can also be used to draw on the rotating disc 4. As the disc 4 rotates, certain patterns can be formed, further increasing the fun and stress-relieving effect of the device.

[0026] In actual use, several sets of evenly arranged counterweight grooves are also provided below the rotating disk 4 near the friction groove 7. According to the requirements, counterweight blocks can be installed in the counterweight grooves. It should be noted that the counterweight blocks should be installed evenly so that the rotating disk 4 can rotate more stably and for a longer period of time.
