[0028] Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the scope of protection of the present utility model.

[0029] It should be noted that like reference numerals denote like elements in the following drawings. Therefore, once an element is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0030] This embodiment mainly describes a heat-insulated cup with adjustable water output as follows:

[0031] As Figures 1 to 9As shown, the thermos cup with adjustable water output comprises a cup body 1, a cup cover 2 and a rotating cover 3, the cup cover 2 has a connecting portion 27 extending into the cup body 1, the connecting portion 27 is provided with an external thread, the inner wall of the mouth of the cup body 1 is provided with an internal thread, the connecting portion 27 is threadedly connected with the cup body 1 and covers the cup mouth of the cup body 1, the rotating cover 3 has an inserting portion 32, the cup cover 2 has a mounting hole 21 connected with the cup body 1, the inserting portion 32 extends into the mounting hole 21 and is rotatably sealed and connected with the mounting hole 21, the inserting portion 32 has a first water outlet channel 33 connected with the cup body 1, the first water outlet channel 33 has a first water outlet 331, the side wall of the cup cover 2 is provided with a second water outlet 22 which can be connected with the first water outlet 331 when the rotating cover 3 rotates, the water in the cup body 1 can flow out from the second water outlet 22 through the first water outlet channel 33 and the first water outlet 331, and the inner wall of the mounting hole 21 is provided with an elastic plug for blocking the first water outlet 331 Block 23, the elastic blocking block 23 and the second water outlet 22 are located on the same circumference, and when the rotating cover 3 is driven to rotate so that the first water outlet 331 and the second water outlet 22 gradually overlap, the water outlet of the first water outlet channel 33 gradually increases; when the rotating cover 3 is rotated until the first water outlet 331 and the second water outlet 22 completely overlap, the water outlet of the first water outlet channel 33 is the largest; when the rotating cover 3 is driven to continue to rotate, the first water outlet 331 and the second water outlet 22 are gradually staggered from the complete overlap state, and the water outlet of the first water outlet channel 33 gradually decreases from the maximum until the side wall of the rotating cover 3 covers the second water outlet 22, the rotating cover 3 is driven to rotate so that the first water outlet 331 cooperates with the elastic blocking block 23 to block the first water outlet 331, and the first water outlet channel 33 is closed. In order to further improve the regulating effect of the water outlet of the first water outlet channel 33, the first water outlet 331 and the second water outlet 22 are both arc-shaped strip holes. This solution adjusts the water output of the water outlet channel by rotating the rotating cover 3 so that the first water outlet 331 and the second water outlet 22 gradually overlap to adjust the water output of the water outlet channel, thereby adjusting the water output of the thermos cup. When the rotating cover 3 is rotated until the first water outlet 331 and the second water outlet 22 completely overlap, the water output of the first water outlet channel 33 is the largest. This solution adjusts the water output of the thermos cup by rotating the rotating cover 3 to control the overlap between the first water outlet 331 and the second water outlet 22. The adjustment is simple and quick, and the water flow can be prevented from shaking when pouring water, reducing the risk of scalding people nearby due to splashing water.

[0032] like Figure 4 , Figure 6 , Figure 8 and Figure 9As shown in the figure, to prevent the rotation cover 3 from being offset and misaligned during rotation, which may cause the rotation cover 3 to be stuck, an inwardly concave annular groove 321 is provided on the outer sidewall of the insertion portion 32, and an elastic convex ring 211 that cooperates with the annular groove 321 is provided on the sidewall of the mounting hole 21. The rotation cover 3 extends into the mounting hole 21 and is connected to the installation chamber through the cooperation of the annular groove 321 and the elastic convex. When the rotation cover 3 rotates, the elastic convex ring 211 slides within the annular groove 321, and the annular groove 321 has a guiding and limiting effect on the elastic convex ring 211.

[0033] As Figure 7 and Figure 8 shown in the figure, to facilitate the elastic plugging block 23 to plug the second water outlet 22 and prevent the elastic plugging block 23 from jamming the first water outlet 331 when the second water outlet 22 needs to be separated from the elastic plugging block 23, the two sides of the elastic plugging block 23 have a first guiding inclined surface 231 and a second guiding inclined surface 232. The settings of the first guiding inclined surface 231 and the second guiding inclined surface 232 make the cross-section of the elastic plugging block 23 a trapezoid with two hypotenuses. Third guiding inclined surfaces 34 and fourth guiding inclined surfaces 35 that respectively cooperate with the first guiding inclined surface 231 and the second guiding inclined surface 232 are provided on the inner sidewalls of both sides of the second water outlet 22. The third guiding inclined surface 34 and the fourth guiding inclined surface 35 gradually decrease in thickness towards the second water outlet 22. The first guiding inclined surface 231, the second guiding inclined surface 232, and the third guiding inclined surface 34 have a guiding effect. When the elastic plugging block 23 plugs the first water outlet 331, the first guiding inclined surface 231 is closely attached to the third guiding inclined surface 34, and the second guiding inclined surface 232 is closely attached to the fourth guiding inclined surface 35.

[0034] As Figure 8 and Figure 9 shown in the figure, the rotation cover 3 includes a circular cover plate 31 and the above-mentioned insertion portion 32. The insertion portion 32 is used to be inserted into the mounting hole 21 to connect with the cup cover 2. The insertion portion 32 and the circular cover plate 31 are integrally formed. The insertion portion 32 is a hollow sleeve, and one end of the sleeve away from the circular cover plate 31 communicates with the cup body 1. An opening is provided on one side of the sleeve away from the cup body 1, and the opening is the above-mentioned first water outlet 331. The sleeve and the first water outlet 331 form the above-mentioned first water outlet channel 33.

[0035] As Figure 4 、 Figure 6 and Figure 9As shown in the figure, a concave first annular step 25 is provided on the top surface of the cup lid 2. The center of the first annular step 25 is collinear with the centers of the circular cover plate 31 and the mounting hole 21. An annular boss 312 that mates with the first annular step 25 is provided on the bottom surface of the circular cover plate 31. When the rotary cover 3 is rotatably connected to the cup lid 2, the annular boss 312 abuts against the annular step. A second annular step 313 that fits against the top of the lid body is provided on the circular cover plate 31. To improve the sealing performance of the thermos cup, a ring groove (not shown in the figure) that mates with the top wall of the cup body 1 opening can be provided on the second annular step 313, and a silica gel ring (not shown in the figure) that mates with the ring groove is provided in the ring groove. When the rotary cover 3 is closed on the opening of the cup body 1, the top wall of the cup body 1 opening extends into the ring groove and the top wall abuts against the silica gel ring, and the silica gel ring seals the cup body 1 opening.

[0036] As Figure 1 shown in the figure, to facilitate the user to quickly determine whether the first water outlet channel 33 is in an open or closed state and the position of the first water outlet 331 on the rotary cover 3, a first mark 311 is provided on the side wall of the circular cover plate 31 directly above the first water outlet 331, and a second mark 24 corresponding to the position of the elastic plug is provided on the side wall of the cup lid 2. When the first mark 311 and the second mark 24 are aligned, the first water outlet 331 is in a closed state. When the first mark 311 rotates above the second water outlet 22, the first water outlet channel 33 is opened. When the first mark 311 and the second mark 24 do not show the above two situations, it means that the first water outlet 331 is in a closed state and leakage may occur.

[0037] As Figure 4 shown in the figure, the mounting hole 21 is a stepped hole. The end of the mounting hole 21 has an abutting step 26 that closely fits against the bottom end of the insertion portion 32. The cooperation between the abutting step 26 and the bottom end of the insertion portion 32 can achieve a water isolation effect and prevent water from entering between the rotary cover 3 and the cup lid 2.

[0038] As Figure 9As shown, a concave second water outlet channel 271 is provided on the side wall of the connecting part 27. The second annular channel communicates with the cup body 1. An annular barrier piece 28 extending along the circumferential direction of the cup cover 2 is provided on the side wall of the cup cover 2. The annular barrier piece is located above the second water outlet channel 271. When the cup cover 2 is covered on the cup body 1, the annular barrier piece 28 abuts against the mouth of the cup body 1 to block the second water outlet channel 271. When the first water outlet channel 33 on the rotating cover 3 is in the closed state, by rotating the cup cover 2, the annular barrier piece 28 on the cup cover 2 moves away from the mouth of the cup body 1, and the second water outlet channel 271 is opened. The water in the cup body 1 can flow out of the heat preservation cup through the second water outlet channel 271. Similarly, when the cup cover 2 is covered on the mouth of the cup body 1, the annular barrier piece 28 abuts against the mouth of the cup body 1 to close the second water outlet channel 271. By rotating the rotating cover 3, the first water outlet 331 coincides with the second water outlet 22, and the first water outlet channel 33 is opened. The water in the cup body 1 flows out from the first water outlet channel 33.
