Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a convenient direct drinking inner plug lid. Background Art

[0002] Currently, there are many varieties of water cups on the market, some of which are designed with straws. These straws are built into the lids for added convenience, especially for children. To ensure consistent air pressure inside and outside the cup when the lid is opened, air holes are created in the lid. During use, air can enter through the holes, maintaining pressure balance inside and outside the cup and facilitating the inhalation of liquid through the straw. However, this also creates a new problem: how to seal the holes when not in use to prevent liquid from overflowing.

[0003] Most existing straw cup lids have an air hole set on the side of the straw bend. When the straw lid is closed, the straw bends and covers the air hole, and the air hole is blocked by squeezing and deforming the straw. However, long-term pressure will quickly cause the straw to deform, thereby reducing the performance of the straw. In addition, in order to prevent the straw from falling and ensure the integrity of the cup, the straw is designed to be integrated with the cup lid. It is difficult to clean it when it becomes dirty after long-term use, and it is difficult to replace the straw when it is deformed or damaged, which is very inconvenient. Utility Model Content

[0006] Preferably, a spring is provided between the lower portion of the slider and the inner wall of the slide groove, and a lower limiting ring is provided on the movable tube below the inner plug.

[0007] Preferably, the movable tube is provided with an external thread, and the lower limiting ring is installed on the movable tube through the thread.

[0008] Preferably, an annular silicone member is provided at the top end of the inner plug, and a water-sealing rib opposite to the silicone member is provided on the inner side of the outer cover.

[0009] Preferably, the inner plug is provided with a plurality of water pouring ports located outside the chute, and the water pouring ports are all through holes.

[0010] Preferably, a limiting shoulder ring is rotatably mounted on the cup body at the bottom of the external mounting thread.

[0011] Preferably, the movable tube is provided with a silicone ring for stabilizing itself.

[0012] After adopting the above structure, the beneficial effects of the utility model are:

[0013] 1. The inner plug cover designed for the water cup of the utility model can automatically pop out the suction nozzle when the outer cover is opened, and is designed with a pouring spout, so that the user can drink or pour water conveniently. After the outer cover is closed, the suction nozzle can be automatically retracted, and the water-sealing ribs in the outer cover squeeze the silicone parts to seal without leaking, preventing dripping. It is simple, convenient and quick to use.

[0014] 2. The inner plug cover for the water cup designed by the utility model has a lower limit ring installed by a thread. After removing it, the movable tube can be removed for cleaning to ensure hygiene. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1-6 As shown, it includes an inner plug 5 arranged in the mouth of the cup body 1, the cup body 1 is provided with an external mounting thread 2, the inner plug 5 is provided in the mouth of the cup body 1, the outer side of the inner plug 5 is provided with an inner plug thread 6, the mouth of the cup body 1 is provided with an internal thread, the inner plug 5 is installed in the mouth of the cup body 1 through the thread, a vertical slide groove is opened in the inner plug 5, the bottom of the slide groove is opened with a hole, a movable tube 10 is slidably installed in the hole, the movable tube 10 is provided with a slider 8 matching the slide groove, and the top of the movable tube 10 is connected to a suction nozzle 7;

[0025] A spring 9 is provided between the bottom of the slider 8 and the inner wall of the chute, and a lower limit ring 11 is provided on the movable tube 10 below the inner plug 5;

[0026] The movable tube 10 is provided with an external thread, and the lower limit ring 11 is installed on the movable tube 10 through the thread;

[0027] The top of the inner plug 5 is provided with an annular silicone member 14, and the inner side of the outer cover 4 is provided with a water sealing rib 13 opposite to the silicone member 14;

[0028] The inner plug 5 is provided with several water pouring ports 12 on the outside of the chute, and the water pouring ports 12 are all through holes;

[0029] A limiting shoulder ring 3 is rotatably mounted on the cup body 1 at the bottom of the external mounting thread 2 , and a silicone ring 15 for stabilizing the movable tube 10 is provided on the movable tube 10 .

[0030] The principle and use process of this utility model:

[0031] When installing, first align the inner plug 5 with the mouth of the cup body 1 and screw it in through the thread to achieve the following Figure 6In the state shown, the spring 9 pushes the suction nozzle 7 upward under the action of its own elastic force, and the top surface of the lower limit ring 11 contacts the bottom surface of the inner plug 5 and stops. In this state, the user can drink water through the suction nozzle 7 or tilt the cup body 1, and water can flow out from the pouring spout 12; then the outer cover 4 is covered and tightened through the outer mounting thread 2. During the installation process of the outer cover 4, the suction nozzle 7 will be pushed downward, driving the movable tube 10 to move downward, and then the spring 9 will be compressed through the slider 8, and the suction nozzle 7 will be retracted into the inner plug 5. The water-sealing rib 13 cooperates with the silicone member 14 for sealing, and the pressure of the spring 9 can make the suction nozzle 7 press against the outer cover 4, automatically blocking the suction nozzle 7 to prevent water from seeping out. Until the outer cover 4 is opened, the spring 9 pushes the suction nozzle 7 to pop out again. During use, the silicone ring 15 guides the movable tube 10 to prevent its angle from deviation or shaking.

[0032] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
