Problems solved by technology

But this thermos cup also has defect, when it is used as quick-cooling thermos cup in heat preservation state, thermal insulation performance is relatively poor, and this is because the hot drinking water in the inner cup directly roasts the salt water through the inner cup so that the salt water evaporates into steam easily. Insulation becomes poor. In addition, salt water tends to splash on the outside of the inner layer when the cup is used for walking or drinking, causing the temperature to drop when there is no need to cool down, which also makes the insulation performance worse.
In addition, this thermos cup has an inner cup, an outer cup, and threads, and the structure is complicated

Embodiment 1

[0035] The thermos cup of embodiment 1 is as figure 1 shown. This example is a thermos cup, including a cup body 1 and a cup cover 2. The cup body 1 includes an inner layer 3, an outer shell 4, and a gap layer 5 between the inner layer 3 and the outer shell 4. The outer shell 4 is provided with a pouring hole 6, and the gap The lower part of the layer 5 is provided with a breath fluid cavity 7, and the breath fluid cavity 7 has a communication hole 8 communicating with the upper part of the gap layer 5. The volume of the breath chamber 7 is less than one-fifth of the volume of the inner layer 3 . Breathing liquid chamber 7 is a rotating breathing liquid chamber 7 . The casing 4 has a concave bottom surface 9 and a skirt 10 , and the pouring hole 6 is arranged on the concave bottom surface 9 of the casing 4 . The volume of the casing 4 skirt 10 below the 6 openings of the pouring holes is equal to the volume of the set cooling water after deducting the occupied volume of the...

Embodiment 2

[0040] The thermos cup of embodiment 2 is as figure 1 , figure 2 shown. The thermos cup of embodiment 2 is a variant of the thermos cup of embodiment 1, and its upper part is exactly the same as that of embodiment 1, only the lower part is different. This example is a thermos cup, including a cup body 1 and a cup cover 2. The cup body 1 includes an inner layer 3, an outer shell 4, and a gap layer 5 between the inner layer 3 and the outer shell 4. The outer shell 4 is provided with filling holes, and the gap layer The lower part of the 5 is provided with a breath fluid cavity 7, and the breath fluid cavity 7 has a communication hole 8 communicating with the upper part of the interstitial layer 5. The breathing liquid cavity 7 of the lower part of the gap layer 5 of the thermos cup in this example is made separately earlier and then pressed into the shell 4 and then welded the contact seam. This also provides a manufacturing method. Breathing liquid chamber 7 is a rotating b...

Embodiment 3

[0043] The thermos cup of embodiment 3 is as figure 1 , image 3 shown. The thermos cup of embodiment 3 is another variant of the thermos cup of embodiment 1. Its upper part is exactly the same as embodiment 1, but the lower part is different. This example is a thermos cup, including a cup body 1 and a cup cover 2. The cup body 1 includes an inner layer 3, an outer shell 4, and a gap layer 5 between the inner layer 3 and the outer shell 4. The outer shell 4 is provided with filling holes, and the gap layer The lower part of the interstitial layer 5 is provided with an interstitial fluid cavity 7, and the interstitial fluid cavity 7 has a communication hole 8 communicating with the upper part of the interstitial layer 5. The volume of the breath chamber 7 is less than one-fifth of the volume of the inner layer 3 . Breathing liquid chamber 7 is a rotating breathing liquid chamber 7 . Both the inflow surface 11 and the outflow surface 12 of the breath chamber 7 are conical s...

Abstract

The invention relates to a vacuum cup, and provides the vacuum cup which has a simple structure, and can alternate between a chilling vacuum cup with improved heat preservation performance and convenience for use and a double-layer vacuum cup. The vacuum cup comprises a cup body and a cup lid, wherein the cup body comprises an inner layer, an outer casing and a gap layer between the inner layer and the outer casing; a filling hole is formed in the outer casing; a liquid cavity is arranged below the gap layer; a communication hole is formed in the liquid cavity and communicated with the upper part of the gap layer. When the filling hole is blocked, the vacuum cup is transformed to the double-layer vacuum cup, while the vacuum cup is transformed to the chilling vacuum cup when the filling hole is blocked after water of which the volume is less than the volume of the liquid cavity is filled into the gap layer through the filling hole. When the cup is used as the chilling vacuum cup, hot drinking water can be cooled quickly to drink after the cup is shaken, so that the thirst of a user can be relieved, and the thirst of multiple people can be relieved through continuously shaking one cup after another and drinking the cooled water. The temperature of the outer casing can be adjusted through shaking the cup slowly for warming hands. Therefore, the vacuum cup has a simple structure, is convenient to use, and is a practical vacuum cup.

Description

technical field [0001] The invention relates to a thermos cup, in particular to a thermos cup which has a simple structure and improved thermal insulation performance when used as a quick-cooling thermos cup and can be switched between a quick-cooling thermos cup and a double-layer thermos cup which are convenient to use. Background technique [0002] The thermos cup is a cup that can keep the temperature of the drinking water in the cup changing slowly. The thermos cup comprises a cup body and a cup cover. Thermos cups include double-layer thermos cups, vacuum thermos cups and foam thermos cups. The cup body of the double-layer thermos cup includes an inner layer, an outer shell and a gap layer (gap) between the inner layer and the outer shell. The inner layer of the double-layer vacuum flask is where drinking water is placed. The gap layer of the double-layer thermos cup is filled with air, the air density is small, and it is not easy to transfer heat, so it is the ther...
