The specific embodiment is as follows:

liquid container 100 (e.g., a vacuum cup) includes a shell 110 (e.g., a cup body), a liner 120, and a cover 160, where shell 110 has a phase change layer 150, liner 120 is located inside shell 110, and a heat exchange cavity 130 is formed between an outer wall of liner 120 and shell 110. The bottom wall of the shell 110 is provided with a convex part, the bottom wall of the liner 120 is provided with a concave part, and the convex part is matched with the concave part, so that the liner 120 and the cup body are reliably positioned. Meanwhile, the opening end of the inner container 120 is provided with a positioning bump 144, and the positioning bump 144 is matched with the inner wall of the cup body, so that the upper part of the inner container 120 is reliably positioned with the inner wall of the cup body, and the positioning of the inner container 120 and the cup body is realized.

As shown in fig. 1, in one embodiment:

the liquid container 100 includes: cup, inner container 120 and lid 160, lid 160 includes first lid body 162, second lid body 168, first sealing ring 164, second sealing ring 166, first passageway 172 and second passageway 174. The first sealing ring 164 is assembled on the first cover body 162 and can be matched with the mouth of the inner container 120, so that the hot water stored in the inner container 120 cannot flow out of the inner container 120, and sealing and heat preservation are realized.

The cup is double-deck hollow structure, and the cavity intussuseption is filled with phase transition layer 150, and its effect can absorb the hydrothermal heat that contacts with the inner wall of cup, makes hot water realize rapid cooling.

The inner bottom wall of the cup body is provided with a convex part which protrudes upwards, and the convex part can be matched with a concave part arranged on the bottom wall of the inner container 120, so that the inner container 120 and the cup body are in a centered position and cannot be eccentric.

The annular cavity formed by the inner wall of the cup body and the outer wall of the liner 120 is a heat exchange cavity 130.

The inner cavity of the inner container 120 is a cavity for storing hot water.

The outer side surface of the opening of the inner container 120 is provided with a plurality of positioning projections 144 protruding outwards, and the positioning projections 144 can be matched with the inner wall of the cup body, so that the opening of the inner container 120 and the cup body are also in a centering position.

The convex part, the concave part and the positioning bump 144 are matched to realize the stable assembly of the inner container 120 and the shell 110, so that the inner container 120 can not swing up and down in the cup body, and the positioning precision can be further improved.

The principle of heat preservation:

the hot water is stored in the inner container 120, at this time, the hot water does not contact with the inner wall of the cup body, and the mouth of the inner container 120 is sealed by the cover body 160, so the heat loss of the hot water is slow, and the heat preservation can be carried out for a long time.

Specifically, the inner container 120 is made of a material having a small thermal conductivity. For example, the plastic inner container 120, the silica gel inner container 120 or the wooden inner container 120 can obtain better heat preservation effect.

Specifically, the inner container 120 may also be a double-layer hollow structure, and the hollow layer is a vacuum layer, so that a better heat preservation effect can be obtained. The double-layer hollow inner container 120 may be a metal inner container 120, a plastic inner container 120, etc., which are not listed here.

The principle of rapid cooling:

the thermos cup is inclined, hot water in the inner container 120 is poured into the heat exchange cavity 130, the hot water is contacted with the inner wall of the cup body, the heat of the hot water is absorbed by the phase change layer 150, and the temperature is rapidly reduced. Meanwhile, because the heat exchange cavity 130 is of an annular structure, only one layer of thin hot water in the heat exchange cavity 130 is in contact with the phase change layer 150 of the shell 110 due to the arrangement, so that the heat absorption efficiency of the phase change layer 150 is high, and the improvement of the cooling speed is facilitated.

As shown in fig. 5, in the cross section of the convex portion, the outline of the convex portion encloses an ellipse or a polygon, such as a rectangle, a square, or the like. In the process of screwing the cover body 160, when the first sealing ring 164 is screwed to contact with the mouth of the inner container 120, the friction force generated by the first sealing ring 164 does not drive the inner container 120 to rotate together, so as to avoid the situation that the cover body 160 is stuck due to the deflection of the inner container 120.

As shown in fig. 6, the number of the positioning projections 144 is 3 or more than 3, so that the mouth of the inner container 120 can be reliably supported and positioned.

As shown in fig. 7, in another embodiment:

in this embodiment, the positioning protrusion 144 is replaced by an elastic positioning portion 146, and the liquid container 100 further includes an elastic ring, the elastic ring is sleeved on the inner container 120, one end of the elastic positioning portion 146 is connected with the elastic ring, and the other end of the elastic positioning portion 146 abuts against the casing 110. When the assembly of the liner 120, the elastic ring and the elastic positioning portions 146 is placed in the cup body, the elastic positioning portions 146 will contact with the inner wall of the shell 110 and be compressed and deformed inward, and because the elastic positioning portions 146 have the same shape and the reaction force generated by the compression is also the same, the liner 120 will be located at the center of the cup body in the horizontal direction, thereby achieving reliable positioning.

The number of the elastic positioning portions 146 is 3 or more, so that the mouth of the inner container 120 can be reliably supported and positioned.

This setting can offset the influence that the processing deviation of cup inner wall diameter and inner bag 120 oral area diameter brought, has better suitability.

As shown in fig. 10, in yet another embodiment:

the mouth of the inner container 120 is provided with a positioning bump 144 and an elastic positioning portion 146, that is, the mouth of the inner container 120 is positioned by the positioning bump 144 and the elastic positioning portion 146 at the same time. The elastic positioning portion 146 is soft elastic positioning, and can offset the influence caused by the processing deviation between the diameter of the inner wall of the cup body and the diameter of the opening of the inner container 120. When the inner container 120 is placed in the cup body, the initial positioning can be performed; in addition, the positioning projection 144 can support and position the mouth of the inner container 120. The positioning protrusions 144 cooperate with the elastic positioning portions 146 to ensure the stability and reliability of the assembly of the inner container 120 and the casing 110.
