Further, the second sub-passage 1164 is located at one side of the switch member 120, and the second passage 118 is located at the other side of the switch member 120, and more particularly, the first sub-passage 1162 and the second passage 118 are located at opposite sides of the switch member 120. This arrangement makes it less likely that hot water in the inner container 320 will flow out of the second passage 118 and scald the user when the heat exchange cavity 330 is filled with hot water through the first and second sub-passages 1162 and 1164 when the thermos cup is tilted, and the use is safer.

Further, the positioning member 200 is engaged with and fixed to the first sealing portion 190, so that the first sealing portion 190 does not rotate when the switch 120 rotates, and the first sealing portion 190 can engage with the wall surface of the switch 120 to effectively seal the inner container 320.

Further, the sliding block 160 is a protrusion disposed on the top of the second blocking member 114, and is matched with the sliding slot 150 on the switch member 120, and in both drinking and sealing states, the sliding block 160 is respectively abutted against the first end and the second end of the sliding slot 150, so as to limit the rotation position of the switch member 120.

Further, as shown in fig. 6 to 9, the switch member 120 is provided with a first communication section 1222 having an L-shape, which is a passage for communicating the inner container 320 and the heat exchange cavity 330.

Further, the side of the switch member 120 is provided with a knob 220 (e.g., the knob 220 is a convex-concave grain structure), which can increase the friction force when the switch member 120 is rotated, and improve the hand feeling.

Further, the switch element 120 is provided with a second communicating section 1224, the second communicating section 1224 is a water outlet channel of the cooled warm water, in a drinking state, the second communicating section 1224 faces the second channel 118, and in a sealing and heat-preserving state, the second communicating section 1224 rotates by a certain angle and is staggered with the second channel 118.

Further, the switch member 120 is provided with an arc-shaped sliding slot 150, and the sliding slot 150 cooperates with the sliding block 160 to define the rotating position of the switch member 120.

Further, a portion of the switch member 120 is mounted in the cover 110 and can rotate at a certain angle relative to the cover 110 to switch between the drinking function and the sealing function.

Further, the limiting member 140 is used to fix the switch member 120 and the cover 110, so that the switch member 120 can rotate around the rotation shaft 130 disposed on the cover 110.

Further, the fourth sealing portion 240 serves to seal a gap between the cup body opening and the second blocking member 114, so as to prevent water in the heat exchange chamber 330 from flowing out of the gap.

Further, the third sealing part 230 is used for sealing the gap between the mouth of the inner container 320 and the first blocking piece 112, and preventing the water in the inner container 320 from flowing out of the gap when the sealing function is locked.

Further, the second sealing part 210 functions to seal a gap between the first blocking member 112 and the opening and closing member 120.

Further, the first sealing portion 190 serves to seal a gap between the first blocking member 112 and the opening/closing member 120, and prevent water in the inner container 320 from flowing out of the gap.

Further, as shown in fig. 10, the first sealing portion 190 is provided with a second opening 1902, and the second opening 1902 can allow hot water in the inner container 320 to pass through. The first sealing portion 190 has a fixing hole, and the fixing hole is matched and fixed with the positioning member 200.

And (3) fast cooling operation:

as shown in fig. 21, the vacuum cup is inclined 90 degrees towards the first direction, the hot water in the inner container 320 can enter the heat exchange cavity 330 through the first passage 116 and the first communication section 1222, the hot water is in contact with the inner wall of the cup body, the heat of the hot water can be absorbed by the phase change layer, and the temperature is rapidly reduced. Meanwhile, because the heat exchange cavity 330 is annular, only a thin layer of hot water in the annular cavity is in contact with the inner wall of the cup body, so that the heat absorption efficiency of the phase change layer is high, and the temperature reduction speed is favorably improved. At this time, the second communicating section 1224 is located above the hot water level in the heat exchange cavity 330, so that the hot water does not directly flow out of the second communicating section 1224, thereby avoiding scalding.

Drinking water operation:

as shown in FIG. 11, by tilting the cup in the second direction, the warm water in the heat exchanger, which has been cooled, can flow out from the second passage 118 and the second communicating portion 1224 and can be drunk directly. The hot water in the inner container 320 cannot flow out because the water level is lower than the first channel 116, so that the hot water in the inner container 320 cannot leak to cause scalding accidents when a user drinks water.

And (3) heat preservation operation:

as shown in fig. 23, when the hot water is temporarily not required, the switch 120 is rotated by a certain angle to displace the first communicating portion 1222 from the first and second sub-passages 1162 and 1164 and to close the first passage 116 by the wall surface of the switch 120, so that the hot water in the inner container 320 cannot flow out of the inner container 320 due to the sealing action of the first and third sealing parts 190 and 230, thereby achieving sealing and heat preservation. At this time, the hot water does not contact the inner wall of the cup body, and the heat conductivity coefficient of the inner container 320 is small, so that the heat loss of the hot water is slow, and the heat preservation can be carried out for a long time.

Meanwhile, after the switch member 120 rotates a certain angle, the second communication section 1224 is staggered with the second channel 118, so that the wall surface of the switch member 120 can seal the second channel 118, thereby ensuring that external dust cannot enter the heat exchange cavity 330 to cause pollution. And the warm water remaining in the heat exchange chamber 330 does not flow out of the second passage 118 to wet the surrounding objects. Through a rotation action of the switch member 120, two functions of hot water heat preservation of the inner container 320 and sealing and dust prevention of the heat exchange cavity 330 can be simultaneously realized, the structure is simple, and the use is convenient.

Example 16:

as shown in fig. 11 and 12, in an embodiment of the present invention, a liquid container 300 (e.g., a vacuum cup) is provided, which includes a casing 310 (e.g., a cup body), an inner container 320 and a cover 110, wherein the casing 310 is provided with a phase change layer, the inner container 320 is located in the casing 310, and a heat exchange cavity 330 is formed between an outer wall of the inner container 320 and the casing 310.

The present embodiment differs from embodiment 15 in that the cover assembly 100 further includes a first sealing member 170 and a second sealing member 180.

As shown in fig. 13, 14 and 15, the switching member 120 is provided with a first mounting groove 250 for mounting the first sealing member 170 and a second mounting groove 260 for mounting the second sealing member 180.

Further, the first installation groove 250 is provided corresponding to the second communication section 1224, and the first installation groove 250 functions to be assembled with the first sealing member 170. Two first mounting posts are disposed in the first mounting groove 250, and the first mounting posts play a role of fixing the first sealing member 170.

Further, the second mounting groove 260 is disposed to be staggered from the first mounting groove 250. The second mounting groove 260 functions to be fitted with the second sealing member 180. Two second mounting posts are arranged in the second mounting groove 260, and the second mounting seat plays a role in fixing the second sealing element 180.

Further, as shown in fig. 16, the second sealing member 180 is provided with a first opening 1802 to allow warm water to pass therethrough when drinking.

Further, the second sealing element 180 is provided with a second fixing hole, and the second fixing hole can be matched and fixed with the second mounting post in the second mounting groove.

Further, as shown in fig. 17, the first sealing member 170 is provided with a first fixing hole, and the first fixing hole can be matched and fixed with the first mounting post in the first mounting groove 250.

Further, as shown in fig. 24, in the drinking state, the first opening 1802 communicates with the second passage 118 and the second communicating section 1224, so that the drinking water can be ensured to be unobstructed. Meanwhile, the warm water flowing out of the second passage 118 does not flow out of the gap between the second blocking member 114 and the opening and closing member 120 by the second sealing member 180, so that it is possible to ensure that the entire warm water flows out of the second communicating section 1224, which improves user experience.

Further, as shown in fig. 25, when the sealing and heat preservation are required, the switch member 120 rotates by a certain angle, at this time, the first sealing member 170 and the second sealing member 180 both rotate by the same angle along with the switch member 120, the second sealing member 180 and the second passage 118 are staggered by a certain angle, and the first sealing member 170 and the second passage 118 are arranged correspondingly, under the sealing action of the first sealing member 170, the temperature rise remaining in the heat exchange cavity 330 cannot flow out from the gap between the second blocking member 114 and the switch member 120, and meanwhile, the second passage 118 has a better sealing effect, and dust can be completely prevented from entering the heat exchange cavity 330 from the gap between the second blocking member 114 and the switch member 120.
