The larger the included angle a is, the less likely the hot water flows out from the second channel 150 to scald the user when the liquid container 200 is tilted to make the hot water in the inner container 220 enter the heat exchange cavity 230 through the first channel 140, and the safer the use is.

The first sealing member 160 is disposed on the bottom surface of the first cover 110, the first sealing member 160 is of an annular structure, and the first sealing member 160 is used for sealing a gap between the opening of the inner container 220 and the first cover 110, so as to prevent hot water in the inner container 220 from directly flowing out from the gap between the opening of the inner container 220 and the first cover 110 and then flowing out from the second channel 150 to scald a user when drinking water. Therefore, the placement of the first seal 160 is critical to the safety of the product. After the first sealing element 160 is screwed on the cover body assembly 100, the sealing is realized by the squeezing action between the cover body assembly 100 and the mouth part of the inner container 220, the sealing performance is good, the reliability is high, and the potential safety hazard can be greatly reduced.

Meanwhile, because heat exchange cavity 230 is of an annular structure, only a thin layer of hot water in the annular cavity contacts the inner wall of shell 210, so that phase change layer 246 has high heat absorption efficiency, and the improvement of cooling speed is facilitated. At this time, the second channel 150 is located above the hot water level in the heat exchange chamber 230, so that the hot water does not directly flow out from the second channel 150, thereby preventing scald.

Drinking water operation:

as shown in fig. 7, by tilting the liquid container 200 toward the second passage 150, the warm water with the reduced temperature in the heat exchange chamber 230 can flow out through the second passage 150 and can be drunk directly. The hot water in the inner container 220 cannot flow out because the water level is lower than the first passage 140. Meanwhile, the hot water in the inner container 220 cannot directly flow out from the gap between the cover assembly 100 and the inner container 220 due to the sealing effect of the first sealing member 160, so that the hot water in the inner container 220 cannot leak to cause scalding accidents when a user drinks water.

Example 15:

as shown in fig. 3, 8 and 9, in an embodiment of the present invention, a liquid container 200 is provided, which includes a housing 210 (e.g., a cup body), an inner container 220 and a cover assembly 100, wherein the inner container 220 is located in the housing 210, and a heat exchange cavity 230 is formed between the inner container 220 and the housing 210.

Example 16 differs from example 15 in that:

the first sealing member 160 has a D-shaped structure, is mounted on the bottom surface of the first cover 110, and has an arc-shaped portion that is fitted to the mouth of the inner container 220, thereby achieving sealing. While the straight (or curved) edge of the D-shaped structure is not attached to the mouth of the inner container 220, the first channel 140 is disposed at the non-attached position.

As shown in fig. 9, when the cooling operation is performed, the liquid container 200 is tilted 90 ° toward the first passage 140, and the hot water in the inner container 220 can flow into the heat exchange chamber 230 through the first passage 140 between the first sealing member 160 and the mouth of the inner container 220 to be cooled. When drinking water, the liquid container 200 is tilted towards the second passage 150, and the warm water with the reduced temperature in the heat exchange cavity 230 can flow out through the second passage 150 for direct drinking. The part of the first sealing member 160 attached to the mouth of the inner container 220 can seal the hot water in the inner container 220, so as to prevent the hot water from flowing out from the gap between the inner container 220 and the cover assembly 100 to cause scald to the user.
