The drinking port is closed by sliding the sliding plate horizontally along the cup lid to cover the upper side of the drinking port, and the drinking port is opened by sliding the sliding plate horizontally along the cup lid away from the drinking port. The drinking port is directly covered by the sliding plate for closing, which causes the sliding plate to easily generate a gap with the surface of the cup lid around the drinking port under the push of the air pressure in the cup body or when the cup shakes, resulting in leakage of the drink in the cup, making it inconvenient to carry the cup out for use. Moreover, there is no vent hole provided on the cup lid, and the air inside and outside the cup cannot circulate through the vent hole to balance the internal and external air pressures while people are using the drinking port to drink, so it is not smooth to drink.

[0038] Such as Figures 1 - 12As shown, as an embodiment of the present invention, a sliding cup cover is provided, which includes a cover body 100, a sliding assembly 200, and a ventilation rotating shaft 300. A slideway member 110 arranged along the length direction is provided at the top of the cover body 100, and a drinking port 101 and a ventilation port 102 respectively penetrate through the cover body 100. The slideway member 110 has a first end a and a second end b arranged along its length direction. The drinking port 101 is arranged near the first end a, and the ventilation port 102 is arranged between the drinking port 101 and the second end b. The sliding assembly 200 includes a sliding base 210 slidably connected to the slideway member 110, a sealing cover 220 rotatably connected to the sliding base 210 for opening or closing the drinking port 101, and an operating member 230 that presses the sealing cover 220 to close the drinking port 101 and is slidably connected to the sliding base 210 along the length direction of the slideway member 110. An elastic member 240 for keeping the sealing cover 220 rotating upward to open the drinking port 101 is provided between the sealing cover 220 and the sliding base 210. The ventilation rotating shaft 300 is arranged above the ventilation port 102 along the width direction of the slideway member 110 and is rotatably connected to the cover body 100. A gas guiding channel 301 misaligned with the ventilation port 102 is provided through the ventilation rotating shaft 300. The operating member 230 has a first stroke and a second stroke that sequentially move toward the second end b under the force applied by the operator. During the first stroke, the operating member 230 slides relative to the sliding base 210 and moves away from the sealing cover 220 to allow the sealing cover 220 to rotate upward to open the drinking port 101. During the second stroke, the operating member 230 drives the sliding base 210 to slide relative to the slideway member 110, and at the same time, the ventilation rotating shaft 300 rotates forward under the push of the sealing cover 220 until the gas guiding channel 301 is connected to the ventilation port 102.The sliding cup cover of this embodiment can be used as a part of the cup. Since both a drinking port 101 and a ventilation port 102 are provided, it can achieve the convection of the gas inside and outside the cup through the ventilation port 102 while people are drinking through the drinking port 101, so as to balance the air pressure inside and outside the cup and realize smooth drinking. The sealing cover 220 is rotatably connected to the sliding base 210, and when the sealing cover 220 closes the drinking port 101, it is pressed by the operating member 230. The sealing cover 220 is tightly closed on the drinking port 101 under the pressing force of the operating member 230, which can prevent the sealing cover 220 from generating a gap with the surface of the cover body 100 around the drinking port 101 under the push of the air pressure inside the cup or when the cup shakes, thus preventing the drink in the cup from leaking from the drinking port 101 and facilitating the portability of the cup when going out. Since the sliding base 210 is slidably connected to the slideway member 110 arranged along the length direction on the top of the cover body 100, and the operating member 230 is slidably connected to the sliding base 210 along the length direction of the slideway member 110, and the drinking port 101 is arranged near the first end a of the slideway member 110, the ventilation port 102 is arranged between the drinking port 101 and the second end b of the slideway member 110, an elastic member 240 for keeping the sealing cover 220 rotating upward to open the drinking port 101 is provided between the sealing cover 220 and the sliding base 210, and a ventilation rotating shaft 300 arranged along the width direction of the slideway member 110 and rotatably connected to the cover body 100 is provided on the upper side of the ventilation port 102. A gas guiding channel 301 misaligned with the ventilation port 102 is provided through the ventilation rotating shaft 300. Therefore, the operator can make the operating member 230 move in the direction of the second end b by applying force to the operating member 230, so that the operating member 230 slides relative to the sliding base 210 in the first stroke and drives the sliding base 210 to slide relative to the slideway member 110 together in the second stroke. At the same time, when the operating member 230 slides relative to the sliding base 210 in the first stroke, it moves away from the sealing cover 220 to allow the sealing cover 220 to rotate upward under the action of the elastic member 240 to open the drinking port 101. When the operating member 230 drives the sliding base 210 to slide relative to the slideway member 110 in the second stroke, it pushes the ventilation rotating shaft 300 to rotate forward through the sealing cover 220 until the gas guiding channel 301 is connected to the ventilation port 102, so that the drinking port 101 and the ventilation port 102 can be opened. The operation is simple and very convenient to use.

[0039] In some specific embodiments, the operating member 230 further has a third stroke and a fourth stroke that sequentially move in the direction of the first end a under the force applied by the operator. During the third stroke, the operating member 230 drives the sliding base 210 to slide relative to the slideway member 110, and at the same time, the ventilation rotating shaft 300 rotates reversely under the push of the sliding base 210 until the air guide channel 301 is misaligned with the ventilation port 102. During the fourth stroke, the operating member 230 slides relative to the sliding base 210 and approaches the sealing cover 220 to press the sealing cover 220 to rotate downward to close the drinking port 101. This enables the operator to move the operating member 230 in the direction of the first end a by applying force, causing the operating member 230 to drive the sliding base 210 to slide relative to the slideway member 110 in the third stroke and relative to the slideway member 110 in the fourth stroke. And during the third stroke when the operating member 230 drives the sliding base 210 to slide relative to the slideway member 110, the ventilation rotating shaft 300 is pushed by the sliding base 210 to rotate reversely until the air guide channel 301 is misaligned with the ventilation port 102. In the fourth stroke, it slides relative to the sliding base 210 and approaches the sealing cover 220 to press the sealing cover 220 to rotate downward to close the drinking port 101, thereby closing the drinking port 101 and the ventilation port 102. The operation is simple and very convenient to use.

[0040] As Figure 7 shown, in some specific embodiments, a first contact portion 201 is provided on the operating member 230, and a second contact portion 202 is arranged on the side of the first contact portion 201 away from the second end b. A first abutting portion 203 is provided on the sliding base 210. During the second stroke, the operating member 230 abuts against the first abutting portion 203 through the first contact portion 201 and pushes the first abutting portion 203 to move in the direction of the second end b to drive the sliding base 210 to slide relative to the slideway member 110. Second abutting portions 204 are provided on the sliding base 210 and the sealing cover 220. During the third stroke, the operating member 230 abuts against the second abutting portion 204 through the second contact portion 202 and pushes the second abutting portion 204 to move in the direction of the first end a to drive the sliding base 210 to slide relative to the slideway member 110. In this embodiment, the second abutting portion 204 is only provided on the sliding base 210. In some other embodiments, the second abutting portion 204 can also be only provided on the sealing cover 220, or the second abutting portion 204 is provided on both the sliding base 210 and the sealing cover 220 to improve the stability and reliability of the second contact portion 202 in pushing the second abutting portion 204 to move.

[0041] As Figure 6 、 Figure 7As shown, in some specific embodiments, the sliding base 210 includes a sliding top plate 211 and two sliding side plates 212 that extend downward along both sides of the length direction of the sliding top plate 211. The sealing cover 220 is arranged between the lower side of the sliding top plate 211 and the two sliding side plates 212, and is rotatably connected to the two sliding side plates 212 through a connecting shaft 250 arranged along the width direction of the slideway member 110, so that the sealing cover 220 can rotate upward relative to the sliding base 210 around the axis of the connecting shaft 250 to open the drinking port 101, or rotate downward to close the drinking port 101. The operating member 230 includes a pressing member 231 arranged between the lower side of the sliding top plate 211 and the upper side of the sealing cover 220, and an operating member 232 arranged on the upper side of the sliding top plate 211 and connected to the pressing member 231 for the operator to apply force. The pressing member 231 presses on the upper surface of the sealing cover 220 to apply a downward pressing force to the sealing cover 220, so as to prevent the sealing cover 220 from generating a gap with the surface of the cover body 100 around the drinking port 101 under the push of the air pressure in the cup or when the cup shakes, thereby preventing the beverage in the cup from leaking from the drinking port and facilitating the portability of the cup when going out.

[0042] As Figure 6As shown, in some specific embodiments, the sealing cover 220 includes a covering end 221 arranged above the drinking port 101, and a connecting end 222 arranged on a side of the covering end 221 close to the second end b along the length direction of the slide member 110 and connected to the covering end 221. The connecting shaft 250 and the elastic member 240 are arranged between the connecting end 222 and the sliding side plate 212, and the covering end 221 is arranged on a side of the connecting shaft 250 away from the second end b, so that the covering end 221 can swing upward to open the drinking port 101 as the sealing cover 220 rotates upward around the axis of the connecting shaft 250, and can swing downward to close the drinking port 101 as the sealing cover 220 rotates downward around the axis of the connecting shaft 250, and the operating member 230 can slide from the end close to the covering end 221 toward the second end b in the first stroke to gradually move away from the sealing cover 220, and at the same time, the sealing cover 220 gradually moves around the axis of the connecting shaft 250 under the action of the elastic member 240. The sealing cover 220 is gradually rotated upward, so that the covering end 221 gradually swings upward with the rotation of the sealing cover 220 to open the drinking port 101. At the same time, the excess gas in the cup can be released from the gradually opened drinking port 101, preventing the covering end 221 from bouncing up and causing the drink in the cup to splash, thereby improving the safety of use; the operating member 230 can slide from the end close to the connecting end 221 toward the first end a in the fourth stroke to gradually approach the sealing cover 220, and at the same time, the sealing cover 220 gradually rotates downward around the axis of the connecting shaft 250 under the pressure of the pressing member 231, so that the covering end 221 gradually swings downward with the rotation of the sealing cover 220 to close the drinking port 101. In addition, the covering end 221 is provided with a sealing member 223 for closing the drinking port 101, and the sealing member 223 is set as a flexible sealing plug, which can move downward with the covering end 221 under the pressure of the pressing member 231 to be interference-connected with the drinking port 101, thereby improving the sealing performance. A first driving member 205 for driving the ventilation shaft 300 to rotate in a positive direction is formed on the connecting end 222 .

[0043] In some specific embodiments, the connecting end 222 includes a connecting portion 2221 and a first extending portion 2222 whose two ends are respectively connected to the connecting portion 2221 and the covering end 221. The connecting shaft 250 is arranged between the connecting portion 2221 and the two sliding side plates 212. The connecting shaft 250 and the closing member 223 are arranged at intervals from each other. The setting of the first extending portion 2222 increases the distance between the closing member 223 and the connecting shaft 250. According to the lever principle, it is convenient for the operator to apply force more easily to slide the operating component 230 relative to the sliding base 210 and press the sealing cover 220 to rotate downward until the closing member 223 is inserted into the drinking port 101 and is interference-connected with the drinking port 101. In this embodiment, a hinge hole is horizontally penetrated on the connecting portion 2221, and the connecting shaft 250 is rotatably inserted into the hinge hole, and the two ends of the connecting shaft 250 respectively extend out of the outside of the hinge hole on the connecting portion 2221 and are rotatably connected to the hinge holes on the two sliding side plates 212. The elastic member 240 is configured as a torsion spring, which is sleeved on the connecting shaft 250, and the torsion arm at one end is connected to the sealing cover 220, and the torsion arm at the other end is connected to the sliding side plate 212. The structure is simple and stable, and the assembly is convenient. In other embodiments, the connecting shaft can also be configured as a convex shaft structure respectively protruding on both sides of the sealing cover 220, or as a convex shaft structure respectively protruding on the inner sides of the two sliding side plates 212, which can also be rotatably connected.

[0044] In some specific embodiments, the connecting end 222 further includes a second extending portion 2223 arranged on a side of the connecting portion 2221 away from the first extending portion 2222 along the length direction of the sliding base and connected to the connecting portion 2221. The second extending portion 2223 can rotate downward around the axis of the connecting shaft 250 to abut against the cover body 100 as the sealing cover 220 rotates upward, so as to limit the sealing cover 220 to rotate upward to an angle to open the drinking port 101, and the angle is less than 90°, especially less than 45°, so that the limiting angle of the upward rotation of the sealing cover 220 is more stable, and the sealing cover 220 is convenient to rotate upward and downward relative to the drinking port 101 around the axial direction of the connecting shaft 250. In addition, the provision of the second extending portion 2223 can also balance the weight of the first extending portion 2222 and the cover end 221, which is conducive to the elastic member 240 driving the sealing cover 220 to rotate upward smoothly. In this embodiment, the first toggle member 205 is formed by a connecting portion 2221 , and two second extending portions 2223 are provided, which are arranged on both sides of the first toggle member 205 , respectively, so that the overall structure of the sliding assembly 200 is compact and stable.

[0045] like Figure 7As shown, in some specific embodiments, a pressing portion 2314 for pressing the sealing cover 220 is provided at the bottom of the pressing member 231. A pressing surface 224 is provided on the top surfaces of the connecting end 222 and the covering end 221. The pressing surface 224 extends from one end close to the connecting portion 2221 to the covering end 221 for contacting the pressing portion 2314. When the sealing cover 220 closes the drinking port 101, the distance between the pressing surface 224 and the operating member 230 gradually decreases from one end close to the connecting end 222 to one end close to the covering end 221. Thus, when the operator applies a force to slide the operating member 230 relative to the sliding base 210 towards the first position, the pressing force of the pressing member 231 on the sealing cover 220 becomes tighter and tighter, so that the closing member 223 is gradually inserted into the drinking port 101 and is in interference fit with the drinking port 101. In addition, when the sealing cover 220 opens the drinking port 101, the distance between the pressing surface 224 and the sliding top plate 211 gradually decreases from one end close to the connecting portion 2221 to one end close to the covering end 221. Thus, when the operating member 230 is in the fourth stroke, that is, when the pressing member 231 slides towards the first end a relative to the sliding base 210, the pressing portion 2314 can slide along the pressing surface 224 from one end close to the connecting portion 2221 to one end close to the covering end 221 and press the pressing surface 224, so that the sealing cover 220 can gradually rotate downward slowly under the cooperation of the pressing portion 2314 and the pressing surface 224 until the closing member 223 is inserted into the drinking port 101 and is in interference fit with the drinking port 101. When the operating member 230 is in the first stroke, that is, when the pressing member 231 slides towards the second end b relative to the sliding base 210, the pressing portion 2314 can slide along the pressing surface 224 from one end close to the covering end 221 to one end close to the connecting portion 2221 and press the pressing surface 224, so that the sealing cover 220 can gradually rotate upward slowly under the cooperation of the pressing portion 2314 and the pressing surface 224 until the closing member 223 leaves the drinking port 101, thereby preventing the covering end 221 from bouncing up suddenly and causing the beverage in the cup to splash. In some other embodiments, the pressing surface 224 may also be provided only on the connecting end 222 or only on the covering end 221.

[0046] As Figure 8As shown, in some specific embodiments, a sliding channel 2111 is provided through the sliding top plate 211 along the length direction of the slideway member 110. The pressing member 231 includes a pressing body 2311 limited to the lower side of the sliding top plate 211 and a sliding member 2312 slidably connected in the sliding channel 2111 and connected to the pressing body 2311. When the operating member 230 slides relative to the sliding base 210, the sliding member slides in the sliding channel 2111, ensuring that the operating member 230 can slide along the length direction of the slideway member 110 in the first stroke and the fourth stroke. The first contact portion 201 is formed by a partial structure of the sliding member 2312, and the first abutting portion 203 is formed by an end wall of the sliding channel 2111 near the second end b. The structure is simplified. In the second stroke, the operating member 230 can push the sliding base 210 to slide towards the second end b by abutting the sliding member 2312 against an end wall of the sliding channel 2111 near the second end b. In some other embodiments, the sliding member 2312 can also be set as a partial structure of the operating member 232, or set as an independent structure connected to the pressing member 231 and the operating member 232 respectively. In this embodiment, a limiting portion 2315 for limiting the sealing cover 220 is further provided at the bottom of the pressing member 231. The limiting portion 2315 is arranged on one side of the pressing portion 2314 near the first end a and can abut against the pressing surface 224 when the second extension portion 2223 abuts against the cover body 100, so as to cooperate with the cover body 100 to position the angle of the sealing cover 220, and the positioning stability is better. An inclined surface 225 is further provided on the top surface of the covering end 221 on one side of the pressing surface 224 away from the second end b. The distance between the inclined surface 225 and the sliding top plate 211 gradually increases from the end near the second end b to the end near the first end a, so as to reduce the overall occupied height of the sealing cover 220 when the second extension portion 2223 abuts against the cover body 100, making the overall structure arrangement of the sliding base 210 more compact.

[0047] As Figure 6 , Figure 7As shown, in some specific embodiments, a positioning block 2316 protrudes from the upper side of the pressing body 2311. The sliding top plate 211 is recessed upward from its bottom surface with a positioning channel 213 arranged along the length direction of the slideway member 110. The positioning channel 213 has a first positioning portion 2131, a second positioning portion 2132, and a sliding surface 2133 located between the first positioning portion 2131 and the second positioning portion 2132. When the operating member 230 is in the first position where the pressing member 231 presses the sealing cover 220 downward to rotate and close the drinking port 101, the positioning block 2316 is limited to the side of the first positioning portion 2131 away from the second end b and cannot easily slide relative to the first positioning portion 2131 toward the second end b, thereby preventing the operating member 230 from sliding randomly relative to the sliding base 210 toward the second end b and accidentally opening the drinking port 101 without opening the drinking port 101. When the operating member 230 is in the second position away from the sealing cover 220 to allow the sealing cover to rotate upward to open the drinking port 101, the positioning block 2316 is limited to the side of the second positioning portion 2132 away from the first end a and cannot easily slide relative to the second positioning portion 2131 toward the first end a, thereby preventing the operating member 230 from sliding randomly relative to the sliding base 210 toward the first end a and accidentally closing the drinking port 101 when the drinking port 101 is opened. When the operating member 230 slides relative to the sliding base 210 between the first position and the second position, the positioning block 2316 slides between the first positioning portion 2131 and the second positioning portion 2132 along the sliding surface 2133 to guide the positioning block 2316 to slide past the first positioning portion 2131 or the second positioning portion 2132 when the operator applies force to the operating member 230. The sliding surface 2133 is respectively connected to the first positioning portion 2131 and the second positioning portion 2132 through arc surfaces, which is beneficial for the positioning block 2316 to slide smoothly along the sliding surface 2133 to the side of the first positioning portion 2131 away from the second end b or the side of the second positioning portion 2132 away from the first end a. The second contact portion 202 is formed by the positioning block 2316, and the second abutting portion 204 is formed by the second positioning portion 2131, which simplifies the structure. When the operating member 230 is in the third stroke, it can abut against the side of the second positioning portion 2131 away from the first end a through the positioning block 2316 and push the second positioning portion 2131 toward the first end a to drive the sliding base 210 to slide relative to the cover body 100 toward the first end a.

[0048] As Figure 4 , Figure 5As shown, in some specific embodiments, the sliding base 210 further includes a second toggle member 206 arranged on a side of the sealing cover 220 away from the first end a and connected to the sliding top plate 211 and the sliding side plate 212. The ventilation shaft 300 includes a shaft body 310 and a swing member 320 protruding from the upper portion of the shaft body 310. The shaft body 310 is arranged on the upper side of the vent 102 along the width direction of the slide member 110 and is rotatably connected to the cover body 100 through a mounting shaft 350 arranged along the width direction of the slide member 110. The swinging member 320 is arranged between the first toggle member 205 and the second toggle member 206, and the air guide channel 301 is set through the rotating shaft body 310. In the second stroke, the operating member 230 abuts against the swinging member 320 through the first toggle member 205, and pushes the swinging member 320 to swing toward the second end b around the axis of the mounting shaft 350, so as to drive the rotating shaft body 310 to rotate forward until the air guide channel 301 is connected with the air vent 102, thereby opening the air vent 102; in the third stroke, the operating member 230 abuts against the swinging member 320 through the second toggle member 206, and pushes the swinging member 320 to swing toward the first end a around the axis of the mounting shaft 350, so as to drive the rotating shaft body 310 to rotate in the opposite direction until the air guide channel 301 and the air vent 102 are misaligned, thereby closing the air vent 102. And because the first toggle member 205 is set as a part of the structure of the sealing cover 220, the sealing cover 220 has the functions of closing the drinking port 101 and opening the vent 102, and the structural design is simple and ingenious. In this embodiment, the second toggle member 206 is connected to the sliding top plate 211 and the two sliding side plates 212 at the same time, and the stability of the connection with the sliding base 210 is good. In other embodiments, the second toggle member 206 can also be connected only to the sliding top plate 211, or only to one or two sliding side plates 212. In this embodiment, the installation shaft 350 is set as a convex shaft structure protruding from both ends of the rotating shaft body 310, which is convenient for assembly on the cover body 100. In other embodiments, the installation shaft can also be set as a convex shaft structure protruding on the cover body 100, or set as an independent structure to be rotatably connected to the rotating shaft body 310 and the cover body 100, and can also be rotatably connected.

[0049] like Figure 8 , Figure 9As shown, in some specific embodiments, the ventilation shaft 300 further includes a first stopper 330 and a second stopper 340 respectively convexly disposed on the upper portion of the shaft body 310, the first stopper 330 being disposed on a side of the swinging member 320 close to the second end b, and the second stopper 340 being disposed on a side of the swinging member 320 close to the first end a. The cover body 100 is provided with a first support platform 103 disposed on a side of the vent 102 close to the second toggle member 206 corresponding to the first stopper 330, and a second support platform 104 disposed on a side of the vent 102 close to the first toggle member 205 corresponding to the second stopper 340. When the ventilation shaft 300 rotates in the positive direction around the axis of the mounting shaft 350 until the first limit piece 330 supports and limits the position on the upper side of the first support platform 103, the air guide channel 301 is connected with the air vent 102, so that the air guide channel 301 can be accurately positioned to the angle connected with the air vent 102 through the mutual support of the first limit piece 330 and the first support platform 103, so as to facilitate the opening of the air vent 102. At this time, the first toggle member 205 abuts against the side of the swing member 320 away from the first limit piece 330, so that the ventilation shaft 300 can be kept at the angle connected with the air guide channel 301 and the air vent 102, so as to prevent the ventilation shaft 300 from rotating relative to the air vent 102 with the movement of the cup, thereby ensuring the stability of the ventilation shaft 300 in opening the air vent 102 when drinking. When the ventilation shaft 300 rotates in the opposite direction around the axis of the mounting shaft 350 until the second limit piece 340 supports and limits the position on the upper side of the second support platform 104, the air guide channel 301 is misaligned with the air vent 102, so that the second limit piece 340 and the second support platform 104 can support each other to accurately position the air guide channel 301 to an angle misaligned with the air vent 102, thereby facilitating the closing of the air vent 102. At this time, the second toggle member 206 abuts against a side of the swinging member 320 away from the second limit piece 340, which can keep the ventilation shaft 300 at an angle misaligned with the air vent 102, thereby preventing the ventilation shaft 300 from rotating relative to the air vent 102 with the movement of the cup, thereby ensuring the stability of the ventilation shaft 300 in closing the air vent 102 when not in use.

[0050] like Figure 6 As shown, in some specific embodiments, the second toggle member 206 includes a fixed plate 2061 connected to the sliding top plate 211 and the sliding side plate 212, and a second toggle portion 2062 extending from the fixed plate 2061 toward the first end a and used to abut against the swing member 320. A receiving groove 2313 is provided on the top pressing member 231 at one end close to the second end b toward the first end a, and when the first contact portion 201 abuts against the first abutting portion 203, the second toggle portion 2062 extends into the receiving groove 2313, so that the overall structure of the sliding assembly 200 is compact and stable.

[0051] like Figure 8 , Figure 9As shown, in some specific embodiments, the cover body 100 includes a cover base P and a flexible seal T that is press-fitted between the cover base P and the ventilation rotating shaft 300. The ventilation port 102 includes a first ventilation channel P1 that is disposed through the cover base P, and a second ventilation channel T1 that is disposed through the flexible seal T and communicates with the first ventilation channel P1. The lower surface of the ventilation rotating shaft 300 is provided with an arc surface 302 arranged around the axis of the mounting shaft 350. The upper surface of the flexible seal T is recessed downward with an arc support surface T2 that fits the arc surface 302. When the ventilation rotating shaft 300 rotates forward around the axis of the mounting shaft 350 until the first limiting member 330 supports and limits the upper side of the first support platform 103, the air guiding channel 301 communicates with the second ventilation channel T1, thereby opening the ventilation port 102 for air guiding; when the ventilation rotating shaft 300 rotates backward around the axis of the mounting shaft 350 until the second limiting member 340 supports and limits the upper side of the second support platform 104, the air guiding channel 301 is misaligned with the second ventilation channel T1, and the arc surface 302 blocks the upper side of the second ventilation channel T1, thereby closing the ventilation port 102 to prevent gas or liquid from flowing out of the ventilation port 102.

[0052] As Figure 3As shown, in some specific embodiments, the slideway member 110 is arranged as a groove structure formed by recessing downward from the top surface of the cover body 100. The sliding assembly 200 is slidably connected within the groove structure. The drinking port 101 and the ventilation port 102 are respectively disposed through the bottom wall of the groove structure. The first end is arranged as one end wall of the groove structure, and the second end is arranged as the other end wall of the groove structure. When the operating member 230 is in the first stroke and the fourth stroke, one end of the sliding base 210 close to the first end a abuts against the first end a for limiting, so as to prevent the sliding base 210 from moving relative to the slideway member 110 along with the operating member 230 when the operating member 230 moves in the first stroke and the fourth stroke; the movement path length of the operating member 230 in the second stroke is limited by one end of the sliding base 210 close to the second end b abutting against the second end b, and the movement path length of the operating member 230 in the third stroke is limited by one end of the sliding base 210 close to the first end a abutting against the first end a to prevent excessive sliding. One end of the sliding base 210 close to the first end a is arranged in a shape matching the first end a, and one end of the sliding base 210 close to the second end b is arranged in a shape matching the second end b, improving the stability of the limit. In this embodiment, the cover body 100 is provided with a drinking edge 105 from its side wall. The first end a is arranged between the drinking port 101 and the drinking edge 105 and is smoothly transitionally connected to the drinking edge 105, which can be used to guide the drink from the drinking port 101 to the drinking edge 105 for people to drink. One end of the sliding top plate 211 close to the first end a is arranged in a shape matching the first end a, which can block above the drinking port 101 when the sealing cover 220 opens the drinking port 101 to prevent the drink from splashing, further improving the safety of use. And when the operating member 230 is in the second stroke, it can drive the sliding base 210 to slide relative to the slideway member 110 until it abuts against the second end b. At the same time, the sliding top plate 211 moves towards the second end b to the side of the area above the drinking port 101 to ensure that the drink can flow along the first end a to the drinking edge 105. One ends of the two sliding side plates 212 close to the first end a are arranged in a shape matching the first end a to further prevent the drink from splashing. One end of the sliding top plate 212 close to the second end b and one side wall of the fixing plate 2061 close to the second end b are arranged in a shape matching the second end b to improve the stability of the limit on the sliding assembly 200. One end of the operating piece 232 close to the first end a is arranged in a shape matching the first end a, which can abut against the first end a for limiting when the sealing cover 220 closes the drinking port 101. One end of the operating piece 232 close to the second end b is arranged in a shape matching the second end b, which can abut against the second end b for limiting when the sealing cover 220 opens the drinking port 101 and moves away from the drinking port 101, thereby further improving the stability of the limit.On both sides of the groove structure arranged along the length direction, air passage channels 112 extending from the bottom wall of the groove to the top surface of the cover body 100 are recessed. Through holes communicating with the air passage channels 112 are provided through the sliding side plates 212. When the operating member 230 is in the second position, the air passage channels are located outside the sliding side plates 212, and the gas flowing out from the drinking port 101 can flow out to the outside through the through holes and the air passage channels. When the operating member 230 is in the third position, the air passage channels are also located outside the sliding side plates 212, and the gas flowing out from the ventilation port 102 can flow out to the outside through the through holes and the air passage channels. In some other embodiments, the slideway member 110 can also be arranged as a track structure arranged along the top surface of the cover body 100, and the sliding base 210 can also be slidably connected to the cover body 100.

[0053] As Figure 9 shown, in some specific embodiments, an arc groove 106 for accommodating the rotating shaft body 310 and a sealing groove 107 located in the middle of the arc groove 106 are recessed downward on the cover base P. The first ventilation passage P1 is provided through the bottom wall of the sealing groove 107. The flexible seal T is installed in the sealing groove 107, reducing the occupation of the internal space of the sliding base 210. The first support platform 103 and the second support platform 104 are respectively arranged as sunken platform structures communicating with the arc groove 106, and can accommodate the first limiting member 330 in the sunken platform structure when the first limiting member 330 abuts against the first support platform 103, and accommodate the second limiting member 340 in the sunken platform structure when the second limiting member 340 abuts against the second support platform 104, thereby further reducing the occupation of the internal space of the sliding base 210 by the ventilation rotating shaft 300.

[0054] As Figure 3 、 Figure 4As shown, in some specific embodiments, second guiding components arranged along the length direction of the slideway member 110 are respectively provided between the two sliding side plates 212 and the two side walls of the slideway member 110. The second guiding components include second guiding channels 111 recessed in the side walls of the slideway member 110 and second guiding members 2121 protruding from the outer sides of the sliding side plates 212 and slidably connected in the second guiding channels 111. When the sliding base 210 slides relative to the slideway member 110, it is guided by the second guiding members 2121 to slide along the second guiding channels 111. The second guiding channels 111 are recessed from the groove structure towards the side part of the cover body 100. Since the second guiding members 2121 are limited in the second guiding channels 111, it can also prevent the sliding base 210 from moving upward out of the slideway member 110. In addition, a third positioning portion 1111 protruding towards the groove structure is provided in the second guiding channels 111. When the operating member 230 is in the first position where the pressing member 231 presses the sealing cover 220 to rotate downward to close the drinking opening 101, the second guiding member 2121 is limited to the side of the third positioning portion 1111 away from the second end b and cannot easily slide relative to the third positioning portion 1111 towards the second end b, thereby preventing the sliding base 210 from sliding randomly towards the second end b relative to the slideway member 110 and accidentally opening the drinking opening 101 without opening the drinking opening 101; when the operating member 230 is in the third position where the sealing cover 220 is away from the upper area of the drinking opening 101 and the air guiding channel 301 is communicated with the ventilation opening 102, the second guiding member 2121 is limited to the side of the third positioning portion 1111 away from the first end a and cannot easily slide relative to the third positioning portion 1111 towards the first end a, thereby preventing the sliding base 210 from sliding randomly towards the first end a relative to the slideway member 110 and accidentally closing the drinking opening 101 or the ventilation opening 102 when the drinking opening 101 is opened. The outer side wall of the third positioning portion 1111 is set as an arc surface. When the sliding base 210 slides relative to the slideway member 110 between the first position and the third position, the second guiding member 2121 slides along the third positioning portion 1111 between the two sides of the third positioning portion 1111 to guide the positioning block 2316 to slide over the third positioning portion 1111 when the operator applies force to the operating member 230. When the operating member 230 is in the first stroke, it slides relative to the sliding base 210 from the first position to the second position; when the operating member 230 is in the second stroke, it drives the sliding base 210 to slide relative to the cover body 100 to the third position where the sealing cover 220 is away from the upper area of the drinking opening 101 and the air guiding channel 301 is communicated with the ventilation opening 102; when the operating member 230 is in the third stroke, it drives the sliding base 210 to slide relative to the cover body 100 to the fourth position where the sealing cover 220 is arranged above the drinking opening 101; when the operating member 230 is in the fourth stroke, it slides relative to the sliding base 210 from the fourth position to the first position.In this embodiment, the fourth position is in the same position as the second position. In other embodiments, the fourth position may also be located between the second position and the first position.

[0055] As Figure 6 , Figure 7 shown, in some specific embodiments, a first guiding assembly arranged along the length direction of the slideway member 110 is disposed between both sides of the pressing member 231 and the two sliding side plates 212 respectively. The first guiding assembly includes a first guiding channel 2122 recessed in the side wall of the sliding side plate 212, and a first guiding member 2317 protruding from the side of the pressing member 231 and slidably connected in the first guiding channel 2122. When the operating member 230 slides relative to the sliding base 210, it is guided by the first guiding member 2317 sliding along the first guiding channel 2122. The first guiding channel 2122 transversely penetrates through the sliding side plate 212. Since the first guiding member 2317 is limited in the first guiding channel 2122, it can also prevent the operating member 230 from moving upward or downward relative to the sliding base 210, improving the connection stability. In addition, the movement length range of the operating member 230 relative to the sliding base 210 can also be limited by the first guiding member 2317 abutting against the two end walls of the first guiding channel 2122 respectively.

[0056] As Figure 13 shown, as another embodiment of the present invention, a cup is further provided, which includes a cup body 400 and the above-mentioned sliding cup cover covering the cup body 400. An internal thread structure is provided around the opening on the inner wall of the cup body 400, and an external thread structure is provided on the outer wall of the cover body 100. The sliding cup cover and the cup body 400 are detachably connected by screwing the external thread structure and the internal thread structure, which is convenient for disassembly and cleaning, and the connection is tight and reliable. A sealing ring sleeved outside the cover body 100 is further provided on the upper side of the external thread structure. The sealing ring is in interference fit between the cover body 100 and the cup body 400 to improve the sealing performance of the cup. Of course, in other embodiments, the sliding cup cover and the cup body 400 may also be detachably connected by a snap structure.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.

[0058] In summary, the above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
