In order to realize the snap connection between the cup body 2 and the cup lid 1, the inner wall of the cup body 2 close to the cup mouth 201 is further provided with a snap portion 203 along the circumferential direction, and the snap 23 on the inner plug 20 of the cup lid 1 is in When the locking button 40 is pushed, it can be engaged with the engaging portion 203 , so that the cup lid 1 and the cup body 2 are engaged with each other.

As shown in FIG. 9 a , when the lid 1 covers the body 2 , the inner plug 20 of the lid 1 is inserted into the mouth 201 of the body 2 , so that the sealing ring 30 is in contact with the water sealing rib 202 . Then, press the locking button 40 downward, and the locking button 40 moves down along the mounting hole 11 until the locking button 40 pushes the catch 23 to move radially outward, so that the catch 23 sticks out of the catch hole 211 and engages with the cup body 2 The part 203 is snap-connected. At this time, the elastic engaging member 50 moves downward along the axial direction to the locking groove 13 along with the locking button 40 , and the locking pin 51 of the elastic engaging member 50 is locked in the locking groove 13 to Locking the locking button 40 to prevent it from continuing to move downward in the axial direction can also continuously provide a pushing force to the buckle 23 , so that the buckle 23 and the engaging portion 203 of the cup body 2 remain in a snap-connected state. When the cup cover 1 and the cup body 2 are closed, the button body 61 of the unlocking button 60 accommodated in the mounting groove 14 is opposite to the side of the outer cover 10 due to the locking pin 51 of the elastic engaging member 50 being disposed in the locking groove 13 . Wall protrudes.

As shown in FIG. 9b , when the cup cover 1 needs to be opened, simultaneously press the button bodies 61 of the unlocking buttons 60 on both sides of the outer cover 10, so that the button body 61 pushes the bayonet 51 to move toward the locking button 40 until the two latches The pins 51 are all accommodated in the fixing holes 411. Under the elastic deformation of the first elastic member 43, the elastic engaging member 50 moves upwards in the axial direction with the locking button 40, and the abutting portion 42 of the locking button 40 also moves upwards. The connecting portion 42 is disconnected from the buckle 23, the buckle 23 loses the pushing force of the locking button 40, and moves into the installation cavity 20a of the inner plug 20 under the elastic deformation force of the second elastic member 233, so that the buckle 23 and the The engaging portion 203 of the cup body 2 is disconnected, the cup cover 1 can be opened from the cup mouth 201, and the user can use the water or other liquids in the cup body.

In the water cup provided by the application, the lid is connected with the cup body, and each component in the lid can be disassembled and cleaned, and the lid can be opened or closed by the unlock button and the lock button on the lid, which is simple and convenient to use. Easy to clean.

The above is only the preferred embodiment of the present application, and the above is only the preferred embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and Changes, any modification, equivalent replacement, improvement, etc. made under the spirit and principle of this application should be included in the protection scope of this application.
