Technical Field
[0001] This utility model relates to drinking water appliances, and more particularly to a semi-screw-on cup lid inner plug with side-discharge water. Background Technology
[0002] The inner stopper of a cup lid is a sealing component used inside containers such as thermos cups. It generally consists of an outer shell and a stopper core inside the outer shell. The stopper core is usually made of stainless steel, silicone, plastic or other materials, and its main function is to prevent liquid leakage from the container and to maintain the internal temperature of the container.
[0003] In the existing technology, when using a water cup with an inner stopper in the lid, the inner stopper needs to be completely removed from the cup body in order to pour out the water. This is inconvenient, and when there is not much water in the cup, the filter screen inside the cup is easily poured out as well. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a side-discharge semi-screwed cup lid inner plug, so that water can be poured without completely removing the inner plug of the cup lid, making the operation convenient.
[0005] The utility model is realized through the following technical solutions:

The outer wall of the cylindrical connecting section is provided with a threaded connection structure. The plug core is threadedly connected to the inner wall of the cup mouth through the threaded connection structure. The bottom of the plug core body is provided with a sealing ring located around the cylindrical connecting section. The sealing ring achieves the seal between the plug core and the cup mouth. A water outlet hole is opened on the cylindrical connecting section. The water outlet hole is located above the threaded connection structure and below the sealing ring.
[0007] As a preferred embodiment of the aforementioned semi-twisted cup lid inner plug, the inner wall of the cylindrical connecting section is provided with a ring of horizontally protruding limiting protrusions near the bottom. The cylindrical connecting section can be detachably installed through the limiting protrusions and the inverted filter screen.
[0008] As a preferred embodiment of the aforementioned semi-twisted cup lid inner plug, the cylindrical connecting section has two water outlet holes, which are centrally symmetrically distributed with respect to the axis of the cylindrical connecting section.
[0009] As a preferred embodiment of the aforementioned semi-twisted cup lid inner plug, the plug core body is covered with an outer shell, which encloses the top wall and outer side wall of the plug core body, and the outer periphery of the outer shell is provided with multiple recessed operating grooves.
[0010] As a preferred embodiment of the aforementioned semi-screw-down cup cap inner plug, the top of the outer shell is provided with a downwardly recessed annular mounting groove. The bottom wall of the annular mounting groove of the outer shell is provided with multiple mounting holes evenly distributed circumferentially. The top of the plug core body is provided with insertion holes at the locations corresponding to the multiple mounting holes. A top buckle ring is embedded in the annular mounting groove of the outer shell. The bottom of the top buckle ring is provided with multiple protrusions corresponding to the multiple mounting holes. Each protrusion passes through the mounting holes on the bottom wall of the annular mounting groove and is inserted into the insertion holes of the plug core body, thereby realizing the installation of the outer shell and the plug core body.
[0011] As a preferred embodiment of the aforementioned semi-twisted cup lid inner plug, a magnet is provided on the top of the plug core body, and the magnetic attraction of the magnet is used to achieve adsorption of the outer shell.
[0012] As a preferred embodiment of the aforementioned semi-screw-down cup lid inner plug, the top of the plug core body and the outer shell are filled with heat-insulating material as a heat-insulating layer.
[0013] As a preferred embodiment of the above-mentioned semi-twisted cup lid inner plug, the top surface of the top buckle ring is provided with a water outlet mark protrusion, and the water outlet mark protrusion corresponds to the position of the water outlet hole.
[0014] This invention has the following advantages over the prior art:
[0015] This utility model provides a side-discharge, semi-screw-down cup lid inner plug. By creating a water outlet hole on the cylindrical connecting section of the inner plug, and positioning the water outlet hole above the threaded connection structure and below the sealing ring, water can be poured out without completely unscrewing the inner plug from the cup body, improving the convenience of pouring. Furthermore, the presence of two water outlet holes on the cylindrical connecting section—one for water discharge and the other for venting—ensures smooth water flow during pouring and eliminates any unusual noises. Additionally, a limiting protrusion on the cylindrical connecting section allows for detachable installation with an inverted filter screen, effectively preventing tea leaves from being poured out or clogging the water outlet hole, and solving the problem of the filter screen being poured out during pouring in existing technologies.

Detailed Implementation
[0020] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0021] See Figures 1 to 3 This embodiment discloses a side-discharge semi-screw-out cup lid inner plug, including a plug core. The plug core includes a plug core body 1 and a cylindrical connecting section 2 located at the bottom of the plug core body 1 and extending downward. The outer wall of the cylindrical connecting section 2 is provided with a threaded connection structure 3, which is an external thread. The plug core is threadedly connected to the inner wall of the cup body opening through the threaded connection structure 3. A sealing ring 4 is provided at the bottom of the plug core body 1 around the cylindrical connecting section 2, which seals the plug core to the cup body opening. A water outlet hole 5 is opened on the cylindrical connecting section 2, located above the threaded connection structure 3 and below the sealing ring 4. In this embodiment, two water outlet holes 5 are opened on the cylindrical connecting section 2, and the two water outlet holes 5 are centrally symmetrically distributed with respect to the axis of the cylindrical connecting section 2. The two opposite water outlet holes 5 are used for water discharge and air discharge during use, ensuring smooth water discharge from the inner plug of the cup lid and avoiding abnormal noise caused by poor airflow during water discharge.
[0022] The inner wall of the cylindrical connecting section 2 has a horizontally protruding limiting protrusion 6 near the bottom. The cylindrical connecting section 2 is detachably installed with the inverted filter screen 7 through the limiting protrusion 6. During use, the installation position of the filter screen 7 can be selected; it can be installed on the cup body or on the inner stopper of the cup lid. When the filter screen 7 is installed on the inner stopper of the cup lid, it effectively blocks tea leaves during pouring, preventing tea leaves from being poured out or clogging the water outlet 5, and preventing the filter screen 7 from being poured out during pouring.
[0023] The stopper body 1 is covered by an outer shell 8, which encloses the top and outer walls of the stopper body 1. The outer shell 8 has multiple recessed operating grooves 9 around its periphery. When screwing the inner stopper of the cup lid, the operator can hold the operating grooves 9 with their fingers to twist it, facilitating the screwing operation. A heat-insulating material is filled between the top of the stopper body 1 and the outer shell 8 as an insulation layer to improve its heat retention effect.
[0024] The top of the outer casing 8 has a downwardly recessed annular mounting groove. Multiple mounting holes are evenly distributed circumferentially along the bottom wall of the annular mounting groove. The top of the plug core body 1 has insertion holes 10 corresponding to these mounting holes. A top retaining ring 11 is embedded in the annular mounting groove of the outer casing 8. The bottom of the top retaining ring 11 has multiple protrusions 12 corresponding to the mounting holes. Each protrusion 12 passes through the mounting holes in the bottom wall of the annular mounting groove and inserts into the insertion holes 10 of the plug core body 1, thus achieving the installation of the outer casing 8 and the plug core body 1. A magnet 13 is provided on the top of the plug core body 1. The magnetic attraction of the magnet 13 helps to attract the outer casing 8, further preventing the outer casing 8 from detaching from the plug core body 1. A water outlet marking protrusion 14 is provided on the top surface of the top retaining ring 11. The water outlet marking protrusion 14 corresponds to the position of the water outlet 5, allowing the user to easily observe the position of the water outlet 5.
[0025] In use, the threaded connection structure 3 of the stopper core is threadedly connected to the inner wall of the cup body opening, thus installing the inner stopper of the cup lid onto the cup body. The sealing ring 4 then contacts the cup body opening to seal the liquid inside the cup.
[0026] When you need to drink water, unscrew the inner stopper of the lid until the water outlet 5 is exposed from the cup body. Stop screwing at this point; the inner stopper is not completely removed from the cup body. Pour the cup, and align one of the water outlets 5 with the water outlet protrusion 14 on the inner stopper so that the water in the cup can be poured out through the downward-facing water outlet 5. The other water outlet 5 serves as a vent, ensuring smooth water flow. This solves the problem in existing technologies where the inner stopper must be completely removed to pour water, ensuring convenient pouring. Because this inner stopper uses a side-discharge water structure, it is relatively novel and more fun for consumers to use.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
