Description

Technical Field

[0001] The utility model relates to the field of thermos cups, in particular to a thermos cup with a manually rotatable cup cover. Background Art

[0002] After searching, Chinese patent document CN220778038U discloses a teapot with a rotating lid, including a pot body, the pot body has an upward opening, the pot body opening is matched with a pot lid, the pot lid includes an upper cover and a lower cover, a bearing ring is clamped between the upper cover and the lower cover, and a handle is fixedly connected to the end of the upper cover away from the lower cover. The upper cover, the lower cover and the bearing ring are arranged, and they are connected together by clamping. In order to facilitate taking the teapot, a handle is also arranged on the left side of the pot body, and the handle is fixedly connected to the pot body. When using, water can be poured by taking the handle without touching the pot body to avoid being scalded. Its working principle is: first, the lower cover is placed horizontally on the table, then the side of the bearing ring with the first ring edge is aligned with the fixed seat of the lower cover, and the first ring edge is pressed down to the bottom of the first clamping edge to make it clamped, and then the second groove of the upper cover is aligned with the side of the bearing ring with the second ring edge, and the second clamping edge in the second groove of the upper cover is pressed to the bottom of the second ring edge to make it clamped. At this point, the upper cover and the lower cover are connected, and the upper cover can be rotated under the action of the bearing ring by moving the upper cover.

[0003] After analysis, it is found that the body of the teapot has a high temperature that can cause burns when in use. Therefore, in order to realize that the upper cover can be rotated by slightly turning it under the action of the bearing ring, and become a decompression toy, and increase the function of the lid, it is necessary to take out the lid and place it on the table as described in the working principle, and then turn the upper cover to turn it into a decompression toy. The lid is not turned directly on the body of the teapot, but must be separated from the body and placed on the table alone to turn the upper cover, so that it can become a decompression toy.

[0004] However, without the lid, the teapot cannot be used normally. For example, dust may fall into the teapot easily, or water may splash out of the opening when the teapot is moved. Moreover, the teapot body is relatively large. Even if no boiling water is put into the teapot, the lid is placed on the teapot body. Figure 4 It can be seen directly and without doubt that the upper cover is in contact with the pot body and objectively cannot rotate due to the existence of friction. The pot can only be rotated after the lid is removed.

[0005] In summary, after searching and analyzing, no thermos cup with a lid that can be manually rotated directly on the cup body has been found. Thus, the present utility model is invented. Utility Model Content

[0006] In view of this, in order to solve the above technical problems, the purpose of the utility model is to provide a thermos cup with a manually rotatable cup cover, which can realize the cup cover being directly rotated on the cup body to achieve the decompression function of the thermos cup.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only partial embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Example 1

[0047] See also Figure 1-Figure 12 As shown, a thermos cup with a manually rotatable cup cover comprises a cup body 1 and a cup cover 2.

[0048] The cup body 1 is provided with an opening 11 at the top; warm water or tea can be filled through the opening 11.

[0049] The cup cover 2 comprises an inverted U-shaped lower cup cover 21 and an inverted U-shaped upper cup cover 22, and a bearing 3 is clamped between the upper cup cover 22 and the lower cup cover 21. The bearing 3 can be a rolling bearing, which includes an inner ring 31 and an outer ring 32, and the inner ring 31 and the outer ring 32 can rotate relative to each other. The lower cup cover 21 covers the opening 11; the upper cup cover 22 covers the lower cup cover 21, so that the side of the upper cup cover 22 is fully or partially covered on the side of the lower cup cover 21, and there is a first gap 23 between the inner side of the upper cup 22 cover and the covered outer side of the lower cup cover 21. In this embodiment, the side of the upper cup cover 22 is selected to partially cover the side of the lower cup cover 21.

[0050] The function of the first gap 23 is to enable the upper cup cover 22 to rotate freely without friction. Fig. 9 As shown, the first gap 23 not only includes the first gap 23 between the inner side of the side of the upper cup cover 22 and the outer side of the covered side of the lower cup cover 21, but also includes the first gap 23 between the inner side of the top of the upper cup cover 22 and the outer side of the covered top of the lower cup cover 21.

[0051] As a specific implementation, the lower cup cover 21 is provided with a first convex column 24, the upper cup cover 22 is provided with a through hole 25, the bearing 3 is installed in the through hole 25, the outer ring 32 of the bearing 3 is fixedly engaged with the upper cup cover 22; the first convex column 24 is inserted into the through hole 25 and is fixedly engaged with the inner ring 31 of the bearing 3. In this way, the lower cup cover 21 is fixedly engaged with the inner ring 31 of the bearing 3; the upper cup cover 22 is fixedly engaged with the outer ring 32 of the bearing 3, the lower cup cover 21 is fixedly covered on the opening 11 of the cup body 1, and the upper cup cover 22 can rotate freely around the lower cup cover 21.

[0052] As a specific embodiment, the cup cover 2 further includes a cap 4, which is provided with a second convex column 41, a first groove 26 is formed at the top of the first convex column 24, the second convex column 41 is inserted and snapped into the first groove 26, and a second gap 27 is provided between the inner side of the cap 4 and the covered outer side of the upper cup cover 22. In this way, the first convex column 24 can be covered, which not only improves the appearance, but also increases the stability of the connection of the first convex column 24.

[0053] As a specific implementation, the top of the upper cup cover 22 is provided with a second groove 28, and the cap 4 is embedded in the second groove 28. The cap 4 can be partially embedded in the second groove 28 or fully embedded in the second groove 28.

[0054] As a specific embodiment, the lower cup cover 21 has an inverted U-shaped first column 211 and a second column 212 extending integrally from the end of the first column 211; the second column 212 and the first column 211 form a step 213 up and down, and the side of the upper cup cover 22 covers the side of the first column 211. The outer diameter of the side of the upper cup cover 22 is equal to the outer diameter of the side of the second column 212 or is basically equal within an acceptable error, so that the upper cup cover 22 and the lower cup cover 21 form a visual effect of being integrated from top to bottom.

[0055] As a specific embodiment, the cup body 1 is fixed with a handle 12. This makes it convenient to carry a portable thermos cup or pour out the water in the cup body.

[0056] The decompression function of the thermos cup in a specific implementation manner is implemented as follows:

[0057] The first one, see Fig.10 As shown, the cup body 1 can be held by hand, and the upper cup cover 22 can be freely rotated around the lower cup cover 21 by the thumb. Depending on the direction of the thumb, it can be rotated clockwise or counterclockwise. Fig.10 Only one direction is indicated. The side of the upper cup cover 22 can be moved from time to time with the thumb, and the upper cup cover 22 will rotate accordingly.

[0058] Similarly, for the second type, see Fig.11 As shown, the handle 12 can be held by hand, and the upper cup cover 22 side can be moved by the thumb, and the upper cup cover 22 can rotate freely around the lower cup cover 21. According to the direction of the thumb moving, it can rotate clockwise or counterclockwise. Figure 11-12 Only one direction is indicated. The side of the upper cup cover 22 can be moved from time to time with the thumb, and the upper cup cover 22 will rotate accordingly.

[0059] Of course, you can also use fingers other than the thumb to move the side of the upper cup cover.

[0060] In summary, since the side of the upper cup cover 22 completely or partially covers the side of the lower cup cover 21, and there is a first gap 23 between the inner side of the upper cup cover 22 and the covered outer side of the lower cup cover 21, it is possible to directly rotate the side of the upper cup cover 22 of the cup body 1. For example, by occasionally flicking the side of the upper cup cover 22 by hand, the upper cup cover 22 can rotate around the lower cup cover 21, thereby realizing the decompression function of the thermos cup.

[0061] Example 2

[0062] Referring to Example 1, on the basis of Example 1, see Figure 13-15As shown, a pattern decoration layer 5 is fixed on the outer side of the upper cup cover 22. The specific pattern of the pattern decoration layer 5 can be designed according to actual needs to form different product styles. This embodiment illustrates one of them.

[0063] Example 3

[0064] Referring to Example 1, the difference from Example 1 is that Fig.16 As shown, the cup body 1 of this embodiment is not provided with a handle, and the decompression function of the thermos cup can be realized mainly in the first way. Fig.10 As shown, by holding the cup body 1 and using the thumb to push the side of the upper cup cover 22 , the upper cup cover 22 can rotate freely around the lower cup cover 21 .

[0065] Example 4

[0066] Referring to Example 1, the difference from Example 1 is that Fig.17 As shown, the cup cover 2 of this embodiment does not include the cap 4, and the top of the first convex column 24 does not have the first groove 26. The upper cup cover 22 is not provided with a through hole 25, but a third groove 252 is provided instead of the through hole 25. The bearing 3 is fixed in the third groove 252, and the first convex column 24 is directly inserted into the inner ring 31 of the bearing 3 for fixing.

[0067] Example 5

[0068] Referring to Example 1, the difference from Example 1 is that Fig.18 As shown, the lower cup cover 21 of this embodiment is not provided with a first convex column, but is provided with a fourth groove 242 instead of the first convex column 24, and the cap 4 is provided with a third convex column 42 instead of the second convex column 41, and the third convex column 42 is inserted and snapped into the fourth groove 242. There is still a second gap between the inner side of the cap 4 and the covered outer side of the upper cup cover 22.

[0069] Example 6

[0070] Referring to Example 1, the difference from Example 1 is that Fig.19 As shown, the cap 4 is provided with a fourth protrusion 43 instead of the second protrusion 41, and the fourth protrusion 43 is inserted into the inner ring 31 of the clamping bearing 3; the lower cup cover 21 is not provided with a first protrusion, but the cap 4 and the lower cup cover 21 are fixed by a T-block, screw, bolt or bolt 44. There is still a second gap 27 between the inner side of the cap 4 and the covered outer side of the upper cup cover 22.

[0071] It should be noted that the "thermos cup" described in the present utility model can also be called a teacup, water cup, teapot, kettle, tea brewing cup, etc., which should not affect the protection scope of the present utility model.
