[0002] A cup is a container for holding liquids in people's daily lives. It can be used to drink water, beverages, tea, etc. People will choose a corresponding cup, such as a coffee cup, based on the material, main functional use, and structural process. Among the existing cups, there are those that allow drinking water in one way, which are divided into direct drinking and straw drinking, and there are also double drinking cups that combine the two drinking methods. This type of cup usually blocks the drinking port by locking the cover or the cover sheet with the side of the cup cover to prevent the liquid in the cup from leaking through the drinking port.

[0003] For example, Chinese utility model patent CN214760438U discloses a double drinking cup, comprising a cup body and a cup cover, wherein the cup cover is provided with a straight drinking port and a suction nozzle port away from the center of the cup body, the cup cover is hinged with a drinking port cover piece which can cover the straight drinking port, the drinking port cover piece is buckled on the cup cover through a snap portion to cover the straight drinking port, and the cup cover is also connected to a drinking suction component of the suction nozzle port, the drinking suction component comprises a drinking suction seat fixed on the suction nozzle port, a suction nozzle which is flippably arranged on the drinking suction seat, a suction nozzle flip slider which is slidably matched on the cup cover, and a suction nozzle cover plate hinged on the cup cover, the suction nozzle cover plate is flipped up and controls the suction nozzle flip slider to slide to drive the suction nozzle to flip upward and expose outside the cup cover, and the suction nozzle cover plate is pressed down to buckle with the cup cover and controls the suction nozzle flip slider to slide to drive the suction nozzle to flip downward and hide in the cup cover.

[0004] The existing drinking mouth cover is generally buckled with the buckle part on the cup lid through the integrated buckle when covering the direct drinking mouth. The drinking mouth cover includes a cover plate and a buckle plate bent downward at one end of the cover plate, and the buckle is arranged on the inner side of the buckle plate. In order to prevent the drinking mouth cover from being disengaged, the buckle plate usually provides a large elastic force to the buckle so that the buckle and the buckle part are tightly clamped.

[0030] Figure 1-Figure 9 As shown, the cup comprises a cup body 1 and a cup cover, and the cup cover can be covered on the cup opening at the upper end of the cup body 1 to seal the cup opening.

[0031] Preferably, the cup cover is threadedly connected to the cup body 1. The connection method between the cup cover and the cup body 1 is not limited to threaded connection, and other conventional connection methods in the art are applicable to this patent.

[0032] Figure 1 , Figure 2 , Figure 4As shown, the cup cover includes a cup cover body 5 and a direct drinking port cover piece 8, the cup cover body 5 is provided with a direct drinking port 14, one end of the direct drinking port cover piece 8 is hinged to the cup cover body 5, and the direct drinking port cover piece 8 can cover the direct drinking port 14 to seal the direct drinking port 14, and a hidden groove 10 is opened on the other end of the direct drinking port cover piece 8, a switch assembly is hidden in the hidden groove 10, the switch assembly includes a lock hook 9 and an elastic member 27, the lock hook 9 is rotatably connected to the direct drinking port cover piece 8 through a support shaft 28, a clamping portion 15 matched with the lower end of the lock hook 9 is provided on the cup cover body 5, and the lock hook 9 can rotate relative to the direct drinking port cover piece 8 under the action of the elastic force of the elastic member 27, so that the lower end of the lock hook 9 is engaged with the clamping portion 15.

[0033] The direct drinking mouth cover 8 is connected by engaging the lock hook 9 with the clamping part 15 on the cup cover body 5. When engaged, the lock hook 9 is always affected by the elastic force of the elastic member 27 and is not easily disengaged from the clamping part 15. When it needs to be opened, the lock hook 9 can be pressed to rotate the lock hook 9 and disengage from the clamping part 15. The direct drinking mouth cover 8 can be opened relatively easily, which improves the user experience. The switch component is hidden in the hidden groove 10 and is not easily touched by mistake. There is no need to set a raised connecting part on the outer surface of the direct drinking mouth cover 8 to connect the lock hook 9, so as to maintain the original shape and contour of the direct drinking mouth cover 8, which is more beautiful.

[0034] Figure 1 As shown, preferably, the locking hook 9 completely covers the hidden groove 10 located on the outer surface of the direct drinking port cover 8, and the outer surface of the locking hook 9 is flush with the outer contour of the direct drinking port cover 8, making the outer surface of the direct drinking port cover 8 look more integrated and more beautiful.

[0035] Preferably, the lock hook 9 includes a side plate 24 and a pressing plate 25 formed by bending the upper end of the side plate 24. The upper end of the side plate 24 is rotatably connected to the groove walls on both sides of the hidden groove 10 through a support shaft 28. The lower end of the side plate 24 has a buckle 26 that is engaged with the clamping portion 15. After the pressing plate 25 is pressed by force, the side plate 24 rotates outward around the support shaft 28 to disengage the buckle 26 from the clamping portion 15.

[0036] Preferably, the elastic member 27 is a return spring, and the two ends of the return spring are respectively supported between the bottom of the hidden groove 10 and the lower surface of the pressing plate 25.
