[0002] A cup cover is a cover that covers the mouth of a cup. It is mainly used to prevent liquid from spilling, maintain the temperature inside the cup, and is hygienic and easy to carry. Depending on the cup and its purpose, the design of the cup cover will also be different. Existing cup covers for thermos cups and plastic travel cups generally only have one way of drinking water. Some cup covers need to be completely removed to drink water directly through the cup body. Some cup covers have straws installed in them to drink water through the straws. Existing cup covers generally cannot integrate both drinking modes at the same time. At the same time, when drinking water, due to the small diameter of the drinking port, in the process of drinking water quickly, due to the pressure difference between the pressure inside the cup body and the pressure in the environment, it is not convenient to carry out air convection, resulting in unstable flow rate. It is not convenient for users to flexibly choose to drink water from the mouth and through the straw through one water outlet. The functionality is poor and it is not convenient for multi-functional drinking. Utility Model Content

[0024] The specific usage scenario of this embodiment is: by setting the cover body 100 to close the top of the cup body, by setting the straw assembly for drinking water through the straw, by setting the water inlet 170 and the spherical rotating block 300 as a detachable structure, it is convenient to form two drinking modes, which is convenient to adapt to the drinking habits of different users and improves the practicality and application scope of the cup cover. After the spherical rotating block 300 is rotated, the through hole 331 can be connected with the water inlet 170, so that when drinking water, the water in the cup body can be introduced into the water spout 330, which is convenient for users to drink.

[0025] Example 2: Figure 1-3 The outer wall of the bottom end of the cover body 100 is provided with an external thread 110, and the external thread 110 is used for threaded sealing connection with the inner wall of the cup, and the outer wall of the front end of the cover body 100 is rotatably connected to the lock buckle 160,

[0026] The inner wall of the lock buckle 160 is connected to the cover body 100 via a return spring. The lock buckle 160 is used to lock the front end outer wall of the upper cover 200 by snap-fitting. The top outer wall of the cover body 100 is fixedly connected to the cup lip 130 .

[0027] The specific usage scenario of this embodiment is: the lock buckle 160 is set to complete the locking and releasing of the upper cover 200. The lock buckle 160 is a conventional setting in the prior art. The cup lip 130 is set to facilitate ergonomics and facilitate good contact with the lips of users when drinking water.

[0028] Example 3: Figure 2 The bottom of the water inlet 170 is fixedly connected to the water inlet pipe 140, the inner wall of the water inlet pipe 140 is connected to the straw through a thread, and the straw extends into the cup body. A buffer hole 150 is opened on the inner wall of the bottom end of the ventilation pipe 180, and the diameter of the buffer hole 150 is larger than the diameter of the through hole inside the ventilation pipe 180.

[0029] The specific usage scenario of this embodiment is: by providing a water intake pipe 140 to facilitate docking with a straw (not marked in the figure), by providing a buffer hole 150 to expand the air inlet diameter at the bottom of the ventilation pipe 180, it is convenient to make the air flow smoother during exchange and improve the fluency when drinking water.

[0030] Example 4: Figure 1 , Figure 4 and Figure 5 The spherical rotating block 300 can rotate around the ear hook 120 synchronously with the upper cover 200. The inner wall of the front end of the spherical rotating block 300 is rotatably connected to the cover plate 320 through the third axis pin. The cover plate 320 is set to be L-shaped. The head end of the cover plate 320 covers the water nozzle 330, and the top of the ventilation pipe 180 and the outer wall of the bottom of the water nozzle 330 cooperate to seal.

[0031] The specific usage scenario of this embodiment is: the cover plate 320 is provided to control the covering and releasing of the water spout 330 , and the spherical rotating block 300 is provided to facilitate the water spout 330 to be turned over.

[0032] The working principle of the utility model is: when using it, a person skilled in the art installs a straw (not marked in the figure) at the bottom of the water intake pipe 140 through a threaded connection, and then thread-seals the cover body 100 with the cup body through the external thread 110. When drinking water is needed, water can be drunk in two ways;

[0033] The first drinking mode: by installing the lock buckle 160, the lock buckle 160 is rotated to adjust the angle, so that the lock buckle 160 releases the upper cover 200, and the upper cover 200 is rotated around the ear hook 120 by holding the upper cover, so that the upper cover 200 carries the spherical rotating block 300 and the cover plate 320 and the water spout 330 to rotate synchronously, so that the water inlet 170 and the vent pipe 180 on the top of the cover body 100 are exposed, and by aligning the cup lip 130 with the mouth, the water in the cup body flows out through the water inlet 170 to the cup lip 130, and then the water in the cup body is guided into the mouth through the cup lip 130 for drinking water, and at the same time, the air convection is carried out between the inside of the cup body and the outer wall environment through the vent pipe 180, so as to keep the air flow pressure inside the cup body consistent with that in the environment, so as to facilitate drinking water more smoothly;

[0034] The second drinking mode: by holding the cover plate 320 and flipping it upward, the cover plate 320 is opened and the water spout 330 is exposed to the outside, and then the cover plate 320 and the water spout 330 are synchronously rotated around the second axis pin 310, so that the through hole 331 on the back of the spherical rotating block 300 is docked with the water intake port 170, and water is sucked through the mouth holding the water spout 330, so that the water in the cup body enters the water intake port 170 through the straw, and then enters the inside of the spherical rotating block 300, and is sucked into the mouth through the water spout 330, and drinking water through the straw is completed. The ventilation pipe 180 is used to maintain the gas circulation inside the cup body, so that the pressure inside and outside the cup body remains consistent, which is convenient for reducing the water absorption resistance.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
