[0031] The existing water cup that can drink 360 degrees has the problems of being unable to operate the cup cover with one hand, being complicated to operate, and the cup cover structure being complicated, time-consuming and laborious to assemble, low production efficiency, and high production cost.

[0032] To solve the above problems, the present application makes improvements and innovations, and proposes the following embodiments.

[0033] In one embodiment, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 The present application provides a cup cover that can drink 360 degrees, which includes a water guide cover 1 and a water permeable cover 2. The water guide cover 1 includes a water guide part 11, which is a horn-shaped structure with a gradually increasing inner diameter in the upward opening direction. The inner side of the lower end of the water guide part 11 is constructed with a downwardly inclined connecting part 12. The lower end of the connecting part 12 is constructed with a first mounting part 13. The inner side wall of the first mounting part 13 is constructed with a mounting ring 131 extending radially inward along the first mounting part 13. The water permeable cover 2 includes a second mounting part 21, which is a hollow cylindrical structure matched with the first mounting part 13. The outer side wall of the second mounting part 21 is constructed with a mounting groove 211 corresponding to the mounting ring 131. The second mounting part 21 is fixedly embedded in the first mounting part 13 through the cooperation of the mounting groove 211 and the mounting ring 131, so as to be fixedly embedded in the water guide cover 1. The upper end of the second mounting part 21 is constructed with a water blocking part 22 covering the second mounting part 21. The connecting part between the second mounting part 21 and the water blocking part 22 is constructed with a plurality of water permeable holes 20 arranged circumferentially. The water permeable holes 20 are in communication with the internal cavity of the water guide cover 1.

[0034] The water blocking part 22 is circumferentially provided with a water sealing part 23 at the upper end. The water sealing part 23 can be folded downward to cover the water permeable holes 20 or folded upward to expose the water permeable holes 20. The connection between the water blocking part 22 and the water sealing part 23 is provided with an operation part 24 for closing the water blocking part 22. When the operation part 24 is pressed downward, the water sealing part 23 changes from the downward folding state to the upward folding state. When the water sealing part 23 is in the upward folding state, the outer end of the water sealing part 23 extends to a position coinciding with the projection of the connecting part 12 in the horizontal plane. When the water sealing part 23 is in the downward folding state, the outer side of the end of the water sealing part 23 presses against the inner side of the connecting part 12 to close the water permeable holes 20.

[0035] Specifically, when the water sealing part 23 is in the downward folding state, the outer side of the end of the water sealing part 23 presses against the inner side of the connecting part 12 to cover and close all the water permeable holes 20. At this time, the cup cover is in the closed state, and the water in the water cup is blocked by the tightly pressed water sealing part 23 and the connecting part 12 after flowing out of the water permeable holes 20, so the water in the water cup cannot flow out. When the operation part 24 is pressed downward, the middle part of the operation part 24 bends downward, which drives the upper end of the water blocking part 22 and the water sealing part 23 to change, so that the water sealing part 23 changes from the downward folding state to the upward folding state. When the water sealing part 23 is in the upward folding state, the water sealing part 23 folds upward away from the inner side of the connecting part 12, thereby simultaneously removing the covering and closing of all the water permeable holes 20, so that all the water permeable holes 20 are in the exposed state. At this time, the cup cover is in the open state, and tilting the water cup can make the water in the water cup flow out through the water permeable holes 20 into the internal cavity of the water guiding part 11, and then the user can drink the water in the water cup through the water guiding effect of the water guiding part 11. When it is necessary to close the cup cover again, pressing the water sealing part 23 downward with the hand can make the water sealing part 23 change from the upward folding state to the downward folding state, so that the water sealing part 23 covers and closes all the water permeable holes 20 again, and the cup cover returns to the closed state.

[0036] In this way, by fixing the water permeable cover 2 in the water guiding cover 1, arranging a plurality of water permeable holes 20 circumferentially on the water permeable cover 2, and arranging the water sealing part 23 for controlling the covering and exposure of the water permeable holes 20, the closing and opening of the cup cover can be controlled. The user can press the operation part 24 with one hand to make the water sealing part 23 change from the downward folding state to the upward folding state to open the cup cover and drink the water in the water cup. The user can press the water sealing part 23 with one hand to make the water sealing part 23 change from the upward folding state to the downward folding state to close the cup cover. The user can close and open the cup cover by one-handed operation, which is simple to operate. The cup cover structure is simple, which is convenient for production and assembly, and is conducive to improving production efficiency and reducing production cost.

[0037] In an alternative, the cup cover allowing 360-degree drinking further comprises a dustproof cover 3; the dustproof cover 3 is a horn-shaped structure with one end open and the other end closed, the open end of the dustproof cover 3 is configured with a buckling part 31, which can be buckled with the upper end of the water guide cover 1 to cover the upper end opening of the water guide cover 1; the closed end of the dustproof cover 3 is configured with a positioning part 32 in the circumferential direction, which matches the water blocking part 23, when the dustproof cover 3 is buckled with the water guide cover 11, the positioning part 32 presses the water blocking part 23 to the downward folding state.

[0038] In this way, when placing the water cup, the upper end opening of the water guide cover 1 can be covered by covering the water guide cover 1 with the dustproof cover 3 to prevent foreign matter from entering the inside of the water cup; at the same time, during the process of covering the water guide cover 1 with the dustproof cover 3, the positioning part 32 on the dustproof cover 3 can replace the human hand to press the water blocking part 23 of the water guide cover 2, so that the water blocking part 23 is deformed and reset from the upward folding state to the downward folding state under the action of the positioning part 32 to close the cup cover. Therefore, the user can appropriately select the use of the dustproof cover 3 according to the use scene, specifically, when the user needs to drink water frequently, the dustproof cover 3 can be directly removed, and the upward folding state or the downward folding state of the water blocking part 23 can be controlled by hand, so that drinking water can be conveniently and efficiently completed; when the user needs to carry the water cup, the dustproof cover 3 can be pressed tightly against the water blocking part 23 and cover the operation part 24 by covering the water guide cover 1 with the dustproof cover 3, so that foreign matter can be prevented from entering the inside of the water cup, and the dustproof cover 3 can prevent the operation part 24 from being opened by mistake during carrying the water cup.

[0039] In an alternative, the cup cover allowing 360-degree drinking further comprises a soft rubber handle 4; the outer side wall of the water guide cover 1 is configured with a fixing part 14 extending radially outwardly from the water guide cover 1, and the soft rubber handle 4 is detachably fixed on the fixing part 14.

By hanging the dustproof cover 3 on the soft rubber handle 4 through the sleeve ring 33, the dustproof cover 3 can still be hung on the soft rubber handle 4 after being removed without affecting the function of covering the water guide cover 1, so that in the use scene where the user needs to drink water frequently, or in the use scene where the user wants to drink water during carrying, the dustproof cover 3 can be hung on the soft rubber handle 4 after being removed, thereby effectively preventing the dustproof cover 3 from being lost.

[0041] In an alternative, the water guide part 11 of the water guide cover 1 is configured with a locking part 15 extending axially along the water guide part 11, the locking part 15 is spaced apart from the first mounting part 13, and the inner side wall of the locking part 15 is configured with a thread, so as to accommodate the connecting section 51 of the cup body 5 through the space between the locking part 15 and the first mounting part 13, and install the water guide cover 1 on the cup body 5 through the locking part 15, so as to realize the connecting and installing of the cup cover and the cup body 5.
