Abstract
Description
Technical Field
[0001] This utility model relates to a teacup, and more particularly to a teacup with a height-adjustable tea strainer. Background Technology
[0002] China has a long history of tea drinking culture, which is deeply loved by people. In traditional tea drinking culture, the precise control of the steeping time is a key factor in determining the flavor of the tea. Different types of tea (such as green tea, black tea, oolong tea, etc.) have strict requirements for the optimal steeping time. Over-steeping will result in a bitter tea, while insufficient time will make it difficult to release the aroma and flavor of the tea leaves.
[0003] Office workers, drivers, and other frequent travelers often use insulated mugs to brew tea. Insulated mugs are convenient to carry and usually have a built-in tea strainer. Tea leaves are placed inside the mug, and the tea is filtered through the strainer before drinking, avoiding the consumption of tea dust. However, this method of brewing tea often results in excessively long steeping times, making it difficult to control the steeping time. Utility Model Content
[0004] The technical objective of this utility model is to address the shortcomings of the existing technology by providing a teacup with a height-adjustable tea strainer.
[0005] The technical solution of this utility model to solve its technical problem is: a teacup with a height-adjustable tea strainer, characterized in that: it includes a cup body, a connecting ring, a cup lid, and a tea strainer; the upper part of the cup body has an external thread at the rim; the opening of the cup lid also has an external thread; the connecting ring has internal threads adapted to the cup body and the cup lid respectively, and is connected to the cup body and the cup lid through the internal threads; the connecting ring includes an upper ring and a lower ring, and an axial limiting device is provided between the upper ring and the lower ring to prevent the upper ring and the lower ring from moving in the axial direction, but the two can rotate. The tea strainer is designed to rotate; a sealing device is provided between the upper and lower rings to prevent leakage; the tea strainer is equipped with a tea strainer cover with a series of filter holes; the side walls of the tea strainer are provided with threads and vertical grooves, and the inner wall of the upper ring is provided with a protruding structure that matches the vertical groove; the tea strainer can rotate synchronously with the upper ring through the cooperation of the protruding structure and the vertical groove; the inner wall of the lower ring is provided with a lifting thread that matches the threads of the tea strainer; when the upper and lower rings are rotated, the tea strainer rotates synchronously with the upper ring, and the lower ring rotates with the tea strainer. Through the action of the lifting thread, the tea strainer moves up and down in the cup.
[0006] The above-mentioned cup lid is a dual-purpose lid. When it is placed on the cup, it can be used as a regular cup lid; when it is removed and placed on the table, it can be used as a small water cup.
[0007] The aforementioned limiting device is a groove between the annular protrusion structure and the raised structure. The upper ring and the lower ring are interlocked by the annular protrusion and the annular groove, so that the two can rotate relative to each other but cannot be separated.
[0008] A sealing ring is provided between the upper and lower rings.
[0009] The aforementioned lower ring includes an outer ring and an inner ring, with a sandwich layer formed between the outer ring and the inner ring; the inner ring is connected to the upper part of the outer ring as a whole, the lower part of the sandwich layer is open, the space inside the sandwich layer is used to accommodate the cup mouth of the cup body, the inner surface of the outer ring is provided with an internal thread that matches the cup mouth of the cup body, and the lifting thread is located on the inner wall of the inner ring.
[0010] Compared with the existing technology, this utility model can control the raising and lowering of the tea strainer by rotating the adapter ring, thereby controlling the steeping time of the tea to achieve the best taste. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figures 1 to 6 As shown, this utility model includes a cup body 5, an adapter ring 4, a cup lid 1, and a tea strainer 7.
[0019] The cup body 5 has the same structure as a regular thermos cup, with external threads at the top rim. The lid 1 is a dual-purpose lid: when attached to the cup, it can be used as a regular lid; when removed and placed on a table, it can be used as a small water cup. The opening of the lid 1 also has external threads.
[0020] The adapter ring 4 is provided with internal threads 13 that are adapted to the cup body 5 and the cup lid 1, and is connected to the cup body 5 and the cup lid 1 respectively through the internal threads 13.
[0021] The adapter ring 4 includes an upper ring 2 and a lower ring 3. An axial limiting device is provided between the upper ring 2 and the lower ring 3, preventing axial movement between them, but allowing rotation. Specifically, the limiting device consists of an annular protrusion structure 12 and a groove between the protrusions. The upper ring 2 and the lower ring 3 are interlocked by the annular protrusion and the annular groove, allowing them to rotate relative to each other without separation. A sealing device, namely a sealing ring 15, is also provided between the upper ring 2 and the lower ring 3 to prevent water leakage.
[0022] The lower ring 3 includes an outer ring 10 and an inner ring 11, with a sandwich layer formed between the outer ring 10 and the inner ring 11. The inner ring 11 is integrally connected to the upper part of the outer ring 10. The lower part of the sandwich layer is open, and the space inside the sandwich layer is used to accommodate the mouth of the cup body 5. The inner surface of the outer ring 10 is provided with an internal thread that matches the mouth of the cup body 5.
[0023] The tea strainer 7 is equipped with a tea strainer cover 6, which has a series of filter holes. The sidewalls of the tea strainer 7 are provided with threads 9 and vertical grooves 8. The inner wall of the upper ring 2 has a protruding structure 12 that matches the vertical groove 8. Through the cooperation of the protruding structure 12 and the vertical groove 8, the tea strainer 7 can rotate synchronously with the upper ring 2, but both can move freely up and down. The inner wall of the inner ring 11 has a lifting thread 14 that matches the threads of the tea strainer 7. When the upper ring 2 and lower ring 3 are rotated, the tea strainer 7 rotates synchronously with the upper ring 2, and the lower ring 3 rotates relative to the tea strainer 7. Through the action of the lifting thread 14, the tea strainer 7 moves up and down in the cup. When the tea strainer 7 moves downwards, the tea leaves are steeped in the water; when the tea strainer 7 moves upwards, the tea leaves are removed from the tea. This allows for independent control of the brewing time.
[0024] When brewing tea, place the tea leaves into the tea strainer 7, close the tea strainer lid 6, and pour in hot water. Rotate the adapter ring 4 to lower the tea strainer 7 into the hot water. After a period of time, rotate the adapter ring 4 in the opposite direction to raise the tea strainer 7 and remove the tea leaves from the water, thus avoiding over-steeping and affecting the taste.
[0025] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
