[0037] As Figure 1 And Figure 2As shown, the utility model relates to a coffee cup with liftable and rotatable sealing structure, it includes cup body 1 and cup cover 2, the top of cup body 1 is cup mouth, cup cover 2 is detachably fixed in cup mouth through the mode of screw thread connection, to seal the cup mouth, avoid the coffee beverage filled in cup body 1 to directly leak from cup mouth, play the role of sealed preservation to beverage, the top of cup cover 2 is provided with direct drinking mouth 201 and straw mouth 202, direct drinking mouth 201 and straw mouth 202 all communicate with the inside of cup body 1, and user can directly drink the coffee beverage in cup body 1 through direct drinking mouth 201, and the aroma of coffee can be fully felt in oral cavity during direct drinking, or the straw is inserted into straw mouth 202 to drink, to accurately control the speed of coffee flowing into oral cavity,

[0038] As Figures 1 to 4 Shown, it also includes screw cap 3, the top of screw cap 3 is formed with water sealing block 301 corresponding to direct drinking mouth 201 and straw mouth 202, and direct drinking mouth 201 and straw mouth 202 are closed by corresponding water sealing block 301, that is to say, the top of screw cap 3 is higher than the top of cup cover 2, so that direct drinking mouth 201 and straw mouth 202 can be closed smoothly, and here, the closed state of direct drinking mouth 201 and straw mouth 202 by screw cap 3 through water sealing block 301 is defined as the initial state thereof;

[0039] As Figures 1 to 4 And Figure 7 And Figure 8 As shown, the top of cup cover 2 is provided with screw groove 204, and the bottom of screw cap 3 is embedded in screw groove 204, and screw cap 3 can move along the axial direction of screw groove 204 and can rotate relative to screw groove 204 in the embedded state, so that screw cap 3 can be directly lifted relative to cup cover 2 by moving along the axial direction of screw groove 204, or can be lifted relative to cup cover 2 by synchronous axial movement when rotating, so that screw cap 3 is out of the initial state, and here, it should be mentioned that when screw cap 3 is lowered only by moving along the axial direction of screw groove 204, it will be limited by the part of cup cover 2 around direct drinking mouth 201 and straw mouth 202 below, hindering its descent, so that the synchronous axial movement is matched when rotating to lift relative to cup cover 2, so that water sealing block 301 moves away from above direct drinking mouth 201 and straw mouth 202, and direct drinking mouth and straw mouth are opened synchronously, to ensure that users can quickly switch the drinking mode in different use situations, solve the problem of switching the drinking mode by repeatedly rotating the screw cap, and the liftable design of screw cap 3 can effectively avoid the nose from contacting screw cap 3 when users drink through direct drinking mouth 201, even when the amount of beverage filled is insufficient and the cup body 1 needs to be held high to drink through direct drinking mouth 201, the nose contact phenomenon can also be avoided, so that users can drink in a comfortable feeling, and solve the problem that the nose contact phenomenon can interrupt the normal drinking rhythm and affect the enjoyment of the beverage.

[0040] Further, the top of the cup cover 2 is also provided with a avoiding groove 203, and a screw groove 204 is arranged in the avoiding groove 203. It is necessary to mention that the depth of the avoiding groove 203 is greater than the height of the top of the screw cover 3. In this way, the top of the screw cover 3 can enter the inside of the avoiding groove 203 during the lifting process along the screw groove 204. When the user drinks through the direct drinking opening 201, the contact with the nose of the user is better prevented, and the occurrence of the nose-touching phenomenon is effectively avoided.

[0041] Further, the lifting of the screw cover 3 relative to the cup cover 2 is mainly realized through the following structure. The inner wall of the screw groove 204 is provided with lifting guide grooves 205. It can be understood that, in order to realize the lifting, the lifting guide grooves 205 extend from the position close to the bottom of the screw groove 204 to the top direction. The lifting guide grooves 205 have two groups, and the two lifting guide grooves 205 are arranged on the two sides of the center surface of the screw groove 204 in a head-to-tail manner. The screw cover 3 is provided with guide blocks 302 corresponding to the lifting guide grooves 205. The guide blocks 302 are in sliding fit with the lifting guide grooves 205, and the lifting guide grooves 205 provide guidance for the guide blocks 302. At the same time, the inner wall of the lifting guide grooves 205 also provides limiting for the guide blocks 302, so as to prevent the whole screw cover 3 from directly separating from the screw groove 204. When the screw cover 3 rotates, the guide blocks 302 synchronously slide along the lifting guide grooves 205. Under the guidance of the lifting guide grooves 205, the height of the guide blocks 302 gradually rises or falls, so as to realize the lifting of the integral screw cover 3 relative to the cup cover 2. At the same time, the direct drinking opening 201 and the straw opening 202 are opened. That is to say, the lifting of the screw cover 3 relative to the cup cover 2 and the opening of the direct drinking opening 201 and the straw opening 202 can be realized through the simple rotating action of the user. The complicated operation steps are simplified, and the user has a better use experience.

[0042] As shown in Figures 5 to 8 The inner wall of the screw groove 204 is provided with side grooves 206 corresponding to the lifting guide grooves 205. The side grooves 206 are located above the lifting guide grooves 205 and are in communication with the top of the screw groove 204. The side grooves 206 allow the guide blocks 302 to enter. When the screw cover 3 rotates and the guide blocks 302 move along the lifting guide grooves 205 to be opposite to the side grooves 206, the user can further lift the screw cover 3, so that the guide blocks 302 can move into the side grooves 206 by inertia. After entering the side grooves 206, the limiting of the inner wall of the lifting guide grooves 205 to the guide blocks 302 is released. Under the action of the lifting force, the guide blocks 302 can move along the side grooves 206 and move to the outside through the upper end of the side grooves 206 which is in communication with the top of the screw groove 204, so that the screw cover 3 can be detached from the cup cover 2. At this time, the screw groove 204 is opened, which is convenient for the user to clean the screw cover 3 and the screw groove 204. The problem that the coffee overflowing from the direct drinking opening 201 or the straw opening 202 cannot be cleaned after overflowing into the screw groove 204 is solved.

[0044] As shown in Figure 9 and Figure 10 , the outer wall of the screw cap 3 is provided with damping silica gel, and the damping silica gel abuts against the inner wall of the screw groove 204, and the damping silica gel will rotate synchronously when the screw cap 3 rotates, at this time, the damping silica gel of silica gel material can generate sufficient sliding friction between the inner wall of the screw groove 204, under the action of the sliding friction, the screw cap 3 can avoid up and down swing when rotating, so as to keep stable rotation, and provide good tactile feedback for the user.

[0045] As shown in Figure 9 and Figure 10 , the damping silica gel has two groups, in the utility model, the two groups of damping silica gel are located on both sides of the center surface of the screw cap 3, so that the sliding friction between the damping silica gel and the inner wall of the screw groove 204 can be evenly distributed around the screw cap 3 when the screw cap 3 rotates, and the rotation of the screw cap 3 is more stable.

[0046] As shown in Figure 9 and Figure 10As shown, the bottom of the water sealing block 301 is correspondingly provided with a water sealing silica gel piece 5, the straight drinking opening 201 and the straw opening 202 are closed by the water sealing silica gel piece 5, the water sealing silica gel piece 5 made of silica gel is non-toxic, odorless, soft and elastic, when the screw cap 3 is in the initial state, the water sealing block 301 exerts pressure on the water sealing silica gel piece 5, under the action of the pressure, the water sealing silica gel piece 5 can be tightly attached to the straight drinking opening 201 and the straw opening 202, eliminating the gap between the fitting positions, effectively preventing the coffee beverage in the cup body 1 from leaking, meanwhile, the silica gel material is resistant to high temperature, avoiding deformation, melting or loss of elasticity when contacting with the high-temperature coffee beverage, so that the sealing effect can still be effectively achieved, and in addition, the water sealing silica gel piece 5 is easy to clean.

[0047] As shown in the figure, Figures 9 to 11 When the screw cap 3 is rotated away from the initial position, the water sealing silica gel piece 5 tightly attached to the straight drinking opening 201 and the straw opening 202 will rotate synchronously, at this time, a large sliding friction force will be generated between the water sealing silica gel piece 5 and the cup cover 2, which may cause the water sealing silica gel piece 5 to deform and deflect, thereby deviating from the preset position and affecting the sealing effect. To this end, the utility model discloses that an upper mounting groove 303 is arranged in the screw cap 3, the two ends of the upper mounting groove 303 are communicated with the ends of the two water sealing blocks 301, an inner lining piece 6 is embedded in the upper mounting groove 303, specifically, the inner lining piece 6 is embedded and mounted from the end of the upper mounting groove 303 communicated with the water sealing block 301, a lower mounting groove 304 is arranged in the bottom of the water sealing block 301, the lower mounting groove 304 is communicated with the upper mounting groove 303, the water sealing silica gel piece 5 is sleeved on the inner lining piece 6 and embedded in the lower mounting groove 304, the above-mentioned arrangement takes the inner lining piece 6 as the support for the water sealing silica gel piece 5, thereby effectively overcoming the problem of deformation and deflection of the water sealing silica gel piece 5 caused by the sliding friction force, and avoiding the sealing effect of the water sealing silica gel piece 5 from being invalid.

[0048] As shown in the figure, Figure 11 A positioning cavity 305 is arranged in the screw cap 3, the positioning cavity 305 is located below the upper mounting groove 303 and is communicated with the upper mounting groove 303, a step surface is formed on the transition position of the upper mounting groove 303, a buckle 601 is formed on the inner lining piece 6, the buckle 601 is buckled on the step surface of the transition position of the positioning cavity 305 and the upper mounting groove 303, thereby avoiding the inner lining piece 6 from being outward of the upper mounting groove 303 and ensuring the stability of the position of the inner lining piece 6 and the connected water sealing silica gel piece 5.
