[0002] Due to its heat preservation and cold preservation performance, the heat-insulated cup is essential in daily life. Generally, a heat-insulated cup is a water container made of ceramics or stainless steel with a vacuum layer. The vacuum heat-insulation layer can slow down the heat dissipation of liquids such as water inside, so as to achieve the purpose of heat preservation.

[0003] For the existing heat-insulated cups, the cup body and the cup lid mostly adopt a separated design. When pouring water, the cup lid needs to be unscrewed and placed separately, which easily leads to the dropping or loss of the cup lid. In addition, most of the straws of the existing heat-insulated cups adopt a bent sealing or non-sealing method, and water leakage is likely to occur at the suction port, which is not conducive to actual use.

[0004] To solve the above problems, a heat-insulated cup is proposed in this application. Content of the Utility Model

[0005] To solve the problems raised in the above background art, the utility model provides a heat-insulated cup, which has the characteristics of preventing the cup lid from dropping and having good sealing performance at the suction port.

A magnetic attraction cap magnetically matched with the magnetic attraction block is rotatably connected to the other side of the top of the cup lid. A connecting plate is arranged inside the water suction port. One side of the connecting plate is provided with a telescopic tube abutted against the inner wall of the magnetic attraction block, and the other side of the connecting plate is provided with a water suction tube extending to the bottom of the cup body.

[0007] Preferably, a limiting groove is formed at the top of the magnetic attraction cap, and the groove width of the limiting groove is equal to the width of the magnetic attraction block.

[0008] Preferably, an ear is provided on one side of the cup lid, and a sealing ring abutted against the top end of the cup body is provided in the middle of the cup lid.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] As Figure 1 and Figure 2 shown;

[0022] A heat-insulating cup, comprising a cup body 1 and a cup lid 2. The cup lid 2 is screwed onto the top of the cup body 1. A temperature display area 3 is provided at the bottom of the cup lid 2. And on one side of the top of the cup lid 2, a water suction port 4 is provided. A magnetic attraction block 5 is buckled outside the water suction port 4. On the other side of the top of the cup lid 2, a magnetic attraction cap 6 magnetically engaged with the magnetic attraction block 5 is screwed; inside the water suction port 4, a connecting plate 7 is provided. On one side of the connecting plate 7, a telescopic tube 8 abutting against the inner wall of the magnetic attraction block 5 is provided. On the other side of the connecting plate 7, a water suction tube 9 extending to the bottom of the cup body 1 is provided. A limiting groove 601 is formed at the top of the magnetic attraction cap 6, and the groove width of the limiting groove 601 is equal to the width of the magnetic attraction block 5.

[0023] It should be noted that: in this embodiment, the temperature display area 3 uses a temperature-changing induction material, which is a microcapsule material that repeatedly changes color with the rise and fall of temperature. It is mainly composed of a capsule wall, a pigment, a color developer and wax. When the temperature is lower than the activation temperature, since the wax solidifies to combine the temperature-changing pigment and the color developer, the microcapsules display color. When the temperature is higher than the activation temperature, the wax will melt, and the pigment and the color developer will automatically separate, so the color will be lost. This change in color is reversible, so that users can intuitively judge the water temperature according to the color change of the temperature display area 3.

[0024] It should be noted that: in this embodiment, the magnetic attraction block 5 is made of a metal material or has a built-in magnetic material, the magnetic attraction cap 6 is a magnetic material, and the magnetic attraction cap 6 can be magnetically adsorbed on the top of the magnetic attraction block 5, so as to realize buckling the magnetic attraction cap 6 on the magnetic attraction block 5, or the magnetic attraction block 5 is adsorbed on the magnetic attraction cap 6.

[0025] In this implementation scheme: the magnetic attraction block 5 and the magnetic attraction cap 6 are magnetically engaged. At the same time, the limiting groove 601 can ensure that the magnetic attraction block 5 is placed more stably, so as to prevent the magnetic attraction block 5 from falling or being lost; by providing the telescopic tube 8 and the connecting plate 7 that are hermetically sealed by mutual extrusion, the telescopic tube 8 can be sealed after the magnetic attraction block 5 is screwed and fixed, so as to avoid leakage near the water suction port 4.

[0026] In an optional embodiment, an ear 10 is provided on one side of the cup lid 2, and a sealing ring 11 abutting against the top end of the cup body 1 is provided in the middle of the cup lid 2.

[0027] In this embodiment: the ear 10 can be used to insert a hanging rope or some decorative pieces, and the sealing ring 11 can improve the sealing performance between the cup lid 2 and the cup body 1.

[0028] As Figure 3 shown;

[0029] In an optional embodiment, a conical sealing block 12 is provided in the middle of the connecting plate 7, and the sealing block 12 is connected to the connecting plate 7 through two groups of connecting rods 13.

[0030] In this embodiment: The telescopic tube 8 and the water suction tube 9 completely cover the sealing block 12 and the connecting rod 13, and both the telescopic tube 8 and the water suction tube 9 are detachably sealed with the connecting plate 7, so as to ensure the replacement and cleaning of the telescopic tube 8 and the water suction tube 9.

[0031] As Figure 4 shown;

[0032] In an alternative embodiment, the telescopic tube 8 includes a straight tube portion 801 and a corrugated portion 802. One end of the straight tube portion 801 abuts against the inner wall of the magnetic attraction block 5, and the corrugated portion 802 is sealingly connected to the connecting plate 7. The opening of the corrugated portion 802 gradually increases in the direction away from the straight tube portion 801, and the maximum diameter of the corrugated portion 802 is greater than the maximum diameter of the sealing block 12, and the inner diameter of the straight tube portion 801 is less than the maximum diameter of the sealing block 12.

[0033] In this embodiment: When the magnetic attraction block 5 is covered, the magnetic attraction block 5 presses the straight tube portion 801 and causes the corrugated portion 802 to contract. At this time, the sealing block 12 enters the straight tube portion 801 and seals it; after the magnetic attraction block 5 is opened, the corrugated portion 802 automatically resets and the straight tube portion 801 moves away from the sealing block 12.

[0034] The working principle and usage process of the present utility model: Open the cup cover 2 and add water to the cup body 1, and then use the cup cover 2 to screw the cup body 1 tightly for sealing; when drinking water is needed, unlock the magnetic attraction block 5 and adsorb it on the magnetic attraction cap 6 by using the limit groove 601. At this time, the straight tube portion 801 pops out under the action of the corrugated portion 802, and drinking water can be carried out by using the straight tube portion 801 and the water suction tube 9, or directly drink by unscrewing the magnetic attraction cap 6; cover the magnetic attraction block 5, the magnetic attraction block 5 presses the straight tube portion 801 and causes the corrugated portion 802 to contract. At this time, the sealing block 12 enters the straight tube portion 801 and seals it.

[0035] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
