Description

Technical Field

[0001] This utility model belongs to the field of water cup technology, and in particular relates to an inner plug for a drinking container. Background Technology

[0002] In existing drinking water container products, such as bullet-shaped insulated cups, travel flasks, and teapots, the mouth is usually equipped with an inner stopper for sealing and water dispensing. The mouth of these products is generally small, and most of the inner stopper is inserted into the mouth. Therefore, drinking water containers with inner stoppers usually have better heat preservation performance.

[0003] However, existing inner plugs are generally made entirely of plastic, including the part of the inner plug that protrudes from the container opening. When the container body is made of metal (such as stainless steel silver, titanium crystal, etc.), the plastic inner plug will not match the metallic color of the body due to its lack of metallic texture, and needs to be improved. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, this utility model provides an inner plug for a drinking container, the part of which exposed at the mouth of the container is covered with a stainless steel or titanium metal layer, so that it can be coordinated with the overall container in a metallic texture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An inner plug for a drinking water container comprises an outer cylinder and an inner cylinder arranged sequentially from the outside to the inside; the upper end of the outer cylinder is open and the lower end has a water inlet, and there is a gap between the outer cylinder and the inner cylinder to form a water outlet channel; a sealing element is movably covered at the water inlet; a driving mechanism is disposed in the inner cylinder for driving the sealing element to open or seal the water inlet; the outer cylinder comprises, from top to bottom, an exposed part that protrudes from the drinking water container and a hidden part that extends into the drinking water container; the exposed part is covered by an outer cylinder metal component.

The connecting buckle is fastened to the fastening holes 216, and a connecting sealing ring is provided between the cylinder body 21 and the cylinder bottom 22 for sealing water tightly.

[0047] In one embodiment, the sealing element 3 includes a sealing plate 31 and a guide rod 32; the guide rod 32 is disposed above the sealing plate 31, and extends into the inner cavity of the inner cylinder 2 through the connecting hole 141 on the connecting part 14 to drive the mechanism; an inlet sealing ring 33 is sleeved on the sealing plate 31 to seal water in close contact with the end face of the inlet 11; a spring buckle 34 is detachably provided at the upper end of the guide rod 32, and a spring 35 is sleeved on the guide rod 32 and placed between the spring buckle 34 and the connecting part 14.

[0048] In one embodiment, the drive mechanism 4 includes at least a button 41 that contacts the top of the guide rod 32. When the button 41 is pressed down, the sealing plate 31 moves away from and opens the water inlet 11, and the water is in the outlet state. When the button 41 is released, the sealing plate 31 reseals the water inlet 11 under the restoring force of the spring 35, and the water is in the sealed state.

[0049] In one embodiment, the drive mechanism 4 further includes a ratchet drive member 42, a ratchet 43, and a limiting structure disposed on the inner surface of the side wall of the cylinder body 21. The button 41, ratchet drive member 42, and ratchet 43 are arranged sequentially from top to bottom, and the button 41 is tightly fitted with the ratchet drive member 42. The ratchet 43 has a positioning groove at its center to accommodate the top of the guide rod 32, and a limiting block 431 protrudes radially outward from its edge, with the top surface of the limiting block 431 being an inclined surface. The ratchet drive member 42... The bottom end is evenly distributed with drive teeth 421, both sides of the drive teeth 421 are inclined surfaces, and the outer surface of its side wall is radially protruding with guide blocks 422; the limiting structure includes circumferentially distributed and protruding on the inner surface of the side wall of the cylinder 21 with locking blocks 44, each locking block 44 is spaced apart to form a guide groove 45, and a locking groove 441 is provided below the locking block 44; the guide block 422 slides up and down in the guide groove 45, and the limiting block 431 jumps and moves in the guide groove 45 or the locking groove 441.

[0050] In this embodiment, pressing button 41 causes ratchet drive 42 to move downwards. The inclined surface of drive tooth 421 presses against the inclined surface of limit block 431 of ratchet 43, causing ratchet 43 to move downwards and rotate. This causes limit block 431 to jump from guide groove 45 into slot 441. At this time, seal 3 moves downwards under the pressure of ratchet 43, opening water inlet 11. Slot 441 also blocks the elastic restoring force of spring 35, keeping it in the water outlet state. Pressing button 41 again causes drive tooth 421 to move ratchet 43 downwards and drive limit block 431 to jump from slot 441 into guide groove 45. At this time, under the elastic restoring force of spring 35, seal 3 resets and seals water inlet 11, maintaining a sealed state.

[0051] In one embodiment, the top of the ratchet drive 42 is provided with a recessed inner cavity, in which a magnetic suction member 46 (preferably a magnet) is placed; in this embodiment, the water cup can also be provided with an outer cover, the top surface of the outer cover is provided with an iron sheet or magnet corresponding to the magnetic suction member 46, which has a magnetic suction component that attracts the magnetic suction member 46, so that the outer cover can be magnetically attached to the inner plug, making it convenient to take off and put on, without the need for additional threaded structure or snap-fit ​​structure, and the appearance is also simpler and drier.
