Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup with tea and water separation. Background Technology

[0002] A thermos flask generally consists of a body and a lid that seals the body tightly. The body typically has an inner liner and an outer liner, with a vacuum insulation layer between them. This vacuum insulation layer slows down the heat dissipation of liquids such as water inside, thus achieving the purpose of keeping the cup warm. Traditional teacups have poor heat retention, causing tea to cool down easily, affecting the taste. To solve this problem, people began to combine the thermos flask with the teacup, designing thermos flasks specifically for brewing tea.

[0003] For example, the Chinese utility model patent "Insulated Tea Cup" with patent publication number CN204600045U includes a cup lid, a receiving cavity and a cup body. The cup lid is provided with an upper internal thread and a lower internal thread, the receiving cavity is provided with a receiving cavity external thread, and the cup body is provided with a cup body external thread. The cup lid is threaded to the receiving cavity external thread through the upper internal thread, and the cup lid is threaded to the cup body external thread through the lower internal thread. After being threaded together, the cup lid, the receiving cavity and the cup body form an integral structure.

[0004] In the above solution, to avoid tea leaves soaking in the cup for an extended period, the cup needs to be inverted each time tea is brewed, and then uprighted after brewing to separate the tea leaves from the water. This process is cumbersome. Furthermore, when users need to drink or change the tea leaves, the container must be removed, and during this process, residual tea leaves can easily spill onto the table or floor, affecting the user experience. Utility Model Content

[0005] This invention addresses the problem of cumbersome tea-brewing process in teacups and the issue of tea residue spilling onto tables or floors when drinking from or changing tea leaves in insulated teacups. The technical problem this invention aims to solve is to provide an insulated cup that separates tea from water.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: It includes a cup body and a cup lid that covers the cup body. The cup lid includes a bottom cover and a rotating cover disposed on the bottom cover. The bottom of the rotating cover has a connecting tube that slides through the bottom cover and extends into the cup body. The rotating cover and the connecting tube can rotate relative to the bottom cover. The cup body has a tea strainer that can slide vertically along the cup body. The tea strainer has a channel through which the connecting tube passes. The connecting tube passes through the channel and is threadedly connected to the channel. The end of the connecting tube has a limiting block to prevent the tea strainer from slipping out. The bottom of the bottom cover has a squeezing block that can extend into the tea strainer. When the rotating cover is rotated clockwise, the connecting tube causes the tea strainer to rise vertically, causing the tea strainer to detach from the tea, and the squeezing block extends into the tea strainer to squeeze the tea leaves. When the rotating cover is rotated counterclockwise, the connecting tube causes the tea strainer to descend vertically, causing the tea strainer to submerge in the water, and the squeezing block extends away from the tea leaves.

[0007] A further preferred embodiment of this utility model is: the channel and the tea strainer wall form a storage compartment for placing tea leaves.

[0008] A further preferred embodiment of this utility model is as follows: an annular platform is provided on the inner wall of the cup body near the mouth of the cup, the edge of the tea strainer has a flange that rests on the annular platform, the inner sides of the cup body have guide grooves that extend vertically to the upper end of the mouth of the cup, and the sides of the tea strainer have sliders that extend outward and into the two vertical guide grooves.

[0009] A further preferred embodiment of this utility model is: the extrusion block is provided with an annular abutment platform whose outer wall abuts against the inner wall of the cup near the bottom cover, and the depth of the tea strainer is equal to the distance from the annular abutment platform to the lower end of the extrusion block.

[0010] A further preferred embodiment of this utility model is: the bottom cover is provided with a through hole through which the extrusion block passes through its top, and the lower end of the connecting pipe passes through the through hole and through the channel to the bottom of the tea strainer.

[0011] A further preferred embodiment of this utility model is: the through hole is a circular stepped hole, the center of the through hole coincides with the center of the bottom cover, the part of the through hole on the bottom cover is a first-level stepped hole, the part of the through hole on the extrusion block is a second-level stepped hole, the diameter of the second-level stepped hole is larger than that of the first-level stepped hole, and the second-level stepped hole can fit the channel inside.

[0012] A further preferred embodiment of this utility model is: the outer wall of the connecting pipe is provided with an external thread, and the inner wall of the channel is provided with an internal thread that mates with the external thread.

[0013] A further preferred embodiment of this utility model is as follows: the rotating cover is provided with a straw groove communicating with the connecting tube, a straw is sleeved inside the connecting tube, the lower end of the straw extends to the bottom of the cup body, the upper end of the straw extends outside the rotating cover, and the rotating cover is provided with a flip cover that presses the upper end of the straw into the straw groove.

[0014] A further preferred embodiment of this utility model is: the lower end of the connecting pipe is provided with U-shaped openings extending vertically to its bottom end on both sides, and there are two limiting blocks, which are respectively located at the ends of the connecting pipe between the two U-shaped openings and extend outward.

[0015] Compared with the prior art, this utility model has the following advantages: By cooperating with the connecting tube on the rotating lid and the channel of the tea strainer, when the rotating lid is rotated, the connecting tube and the channel threadedly engage to drive the tea strainer to slide up and down vertically along the cup body. When the rotating lid is rotated clockwise, the connecting tube drives the tea strainer to rise vertically, thus separating the tea strainer from the tea in the cup. This avoids the tea from being soaked in the cup for a long time, which affects the taste of the tea. At the same time, the squeezing block extends into the tea strainer to squeeze the tea leaves, squeezing out excess tea from the tea leaves. This prevents residual tea from spilling onto the ground or table when changing tea leaves or opening the cup lid, thus improving the user experience. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] This embodiment mainly describes a thermos cup with tea and water separation, as detailed below:

[0029] like Figures 1 to 8As shown, a thermos cup with tea-water separation includes a cup body 1 and a lid 2. The lid 2 is located at the mouth of the cup body 1 to close the mouth of the cup body 1. The lid 2 consists of a bottom cover 21 and a rotating cover 22 located on the top surface of the bottom cover 21. The bottom cover 21 is threadedly connected to the cup body 1. The bottom of the rotating cover 22 has a connecting tube 3 that slides through the bottom cover 21 and extends into the cup body 1. The rotating cover 22 and the connecting tube 3 can rotate relative to the bottom cover 21. A tea strainer 4 is provided inside the cup body 1 and can slide vertically along the cup body 1. The tea strainer 4 has an upward-opening barrel-shaped structure and is used to hold tea leaves. The tea strainer 4 has a channel 41 through which the connecting tube 3 passes, and the connecting tube 3 passes through the channel 41 and is threadedly connected to the channel 41. A limiting block 5 is provided at the end of the connecting tube 3 to prevent the tea infuser 4 from slipping out. A squeezing block 6, which can extend into the tea infuser 4, is provided at the bottom of the bottom cover 21. The squeezing block 6 is used to squeeze the tea leaves, forcing any remaining tea water into the cup body 1. When the rotating cover 22 is rotated clockwise, the threaded connection between the connecting tube 3 and the channel 41 causes the tea infuser 4 to rise vertically, separating the tea infuser 4 from the tea water in the cup body 1. This prevents the tea water from being soaked in the cup body 1 for a long time, thus affecting the taste of the tea. Simultaneously, as the tea infuser 4 rises with the connecting tube 3, the squeezing block 6 extends into the tea infuser 4 to squeeze the tea leaves, squeezing out excess tea water. This prevents any remaining tea water from spilling onto the floor or table when changing tea leaves or opening the cup cover 2, improving the user experience. When the rotating cover 22 is rotated counterclockwise, the threaded connection between the connecting tube 3 and the channel 41 causes the tea infuser 4 to descend vertically, submerging it in the water. At this time, the squeezing block 6 is away from the tea leaves, and the tea leaves are soaking in the water; this is the brewing state. During use, simply rotate the rotating cover 22 clockwise to separate the tea from the water and squeeze the tea leaves. It is simple and convenient to operate.

[0030] like Figure 6 and Figure 8 As shown, the passage 41 and the tea strainer 4 form a storage chamber 42 for placing tea leaves. The storage chamber 42 provides a dedicated storage space for tea leaves. The tea leaves can be fully soaked in water in the storage chamber 42. At the same time, when the tea strainer 4 rises, the tea leaves are confined in the storage chamber 42 and will not scatter with the movement of the tea strainer 4, thus ensuring the effect of tea-water separation.

[0031] like Figure 4 , Figure 6 and Figure 8As shown, to enable the vertical sliding of the tea strainer 4, an annular platform 11 is provided on the inner wall of the cup body 1 near the rim. The edge of the tea strainer 4 has a flange 43 that rests on the annular platform 11. Guide grooves 12 extending vertically to the upper end of the rim are located on both sides of the inside of the cup body 1. Slider blocks 44 extend outwards from both sides of the tea strainer 4 and enter the guide grooves 12. The sliders 44 slide within the guide grooves 12, allowing the tea strainer 4 to move smoothly up and down along the vertical direction of the cup body 1. This ensures the smoothness and stability of the tea strainer 4's movement when rotating to the rotating lid 22, further improving the reliability of tea-water separation. Simultaneously, the design of the guide grooves 12 allows the tea strainer 4 to be removed along with the lid 2 when it is opened, eliminating the need to handle the tea strainer 4 by hand and preventing burns caused by the high temperature of the tea strainer 4.

[0032] Specifically, the extrusion block 6 is provided with an annular abutment platform 61 near the bottom cover 21, with its outer wall abutting against the inner wall of the cup body 1. The depth of the tea strainer 4 is equal to the distance from the annular abutment platform 61 to the lower end of the extrusion block 6. When there is no tea in the tea strainer 4, the rotating cover 22 is rotated to make the tea strainer 4 move upward along the guide groove 12. When the tea strainer 4 rises to its bottom and contacts the bottom end of the extrusion block 6, the annular abutment platform 61 simultaneously abuts against the flange 43 of the tea strainer 4.

[0033] like Figure 6 As shown, the bottom cover 21 has a through hole 7 that passes through the pressing block 6 from its top. The lower end of the connecting tube 3 passes through the through hole 7 and through the channel 41 to the bottom of the tea infuser 4. The through hole 7 is a circular stepped hole, with the center of the through hole 7 coinciding with the center of the bottom cover 21. The part of the through hole 7 on the bottom cover 21 is the first-level stepped hole 71, and the part of the through hole 7 on the pressing block 6 is the second-level stepped hole 72. The diameter of the second-level stepped hole 72 is larger than that of the first-level stepped hole 71, and the second-level stepped hole 72 can fit the channel 41 inside. The stepped hole design also increases the stability of the structure, ensuring that the raising and lowering of the tea infuser 4 is not obstructed, and improving the overall performance of the thermos.

[0034] like Figure 4 As shown, the design of the through hole 7 makes the extrusion block 6 form a cylindrical structure. When the extrusion block 6 is inserted into the placement chamber 42, the outer ring of the extrusion block 6 fits against the inner wall of the placement chamber 42, and the inner ring of the extrusion block 6 fits against the outer periphery of the channel 41. This design allows the extrusion block 6 to fully contact the tea leaves, which can quickly squeeze out the excess tea water from the tea leaves, improve the efficiency and effect of tea water separation, and prevent tea water from spilling.

[0035] Specifically, the connecting tube 3 has external threads on its outer wall, and the channel 41 has internal threads on its inner wall that mate with the external threads. Through this threaded connection, the connecting tube 3 and the channel 41 can fit tightly together. When the rotating cover 22 rotates, the connecting tube 3 can smoothly raise and lower the tea infuser 4, achieving precise tea-water separation. This threaded connection design not only ensures the stability of the tea infuser 4's raising and lowering but also makes the connection between the tea infuser 4 and the connecting tube 3 more robust, improving the overall structural strength of the thermos.

[0036] like Figure 7 and Figure 8 As shown, the rotating lid 22 has a straw groove 8 that communicates with the connecting tube 3. A straw 9, made of silicone, is fitted inside the connecting tube 3. The lower end of the straw 9 extends to the bottom of the cup body 1, and the upper end extends beyond the rotating lid 22 to form a mouthpiece. The rotating lid 22 has a flip-top 10 that presses the upper end of the straw 9 into the straw groove 8. This design allows users to drink tea directly through the straw 9 without opening the lid 2, which is both convenient and hygienic. At the same time, the flip-top 10 prevents the straw 9 from falling off during carrying, ensuring the airtightness and heat preservation performance of the thermos.

[0037] like Figure 7 As shown, the lower end of the connecting tube 3 has U-shaped openings 31 extending vertically to its bottom on both sides. Two limiting blocks 5 are located at the ends of the connecting tube 3 between the two U-shaped openings 31 and extend outwards. This design of the limiting blocks 5 effectively restricts the slippage of the tea infuser 4, ensuring that the tea infuser 4 does not detach from the connecting tube 3 during lifting and lowering, thus improving the safety and reliability of the thermos. Simultaneously, by squeezing the portion between the two U-shaped openings 31, the ends of the connecting tube 3 can be deformed, causing the two limiting blocks 5 to slip out of the channel 41, thereby removing the tea infuser 4. Preferably, the edges of the two limiting blocks 5 are arc-shaped curved surfaces that mate with the channel 41.

[0038] When brewing tea, rotate the rotating cover 22 counterclockwise. The connecting tube 3, through its threads, drives the tea strainer 4 to descend along the guide groove 12, completely immersing the tea strainer 4 in the tea water. The tea leaves are fully soaked in the placement chamber 42. At this time, the squeezing block 6 is away from the tea leaves to avoid interfering with the brewing process. After brewing, rotate the rotating cover 22 clockwise. The connecting tube 3, through its threads, drives the tea strainer 4 to rise, detaching the tea strainer 4 from the tea water and separating the tea leaves from the tea water to prevent over-soaking. When it is necessary to change the tea leaves or clean the tea strainer 4, first rotate the rotating cover 22 clockwise to make the squeezing block 6 squeeze the tea leaves in the tea strainer 4, squeezing out the tea water. Then, remove the cup lid 2 and press the U-shaped opening 31 at the end of the connecting tube 3 to make it elastically deform. The limiting block 5 can slide out of the channel 41, allowing the limiting block 5 to detach from the tea strainer 4 through the channel 41.
