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

[0030] The thermos cup of embodiment 1 is as figure 1 shown. A thermos cup according to the present invention comprises 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, the gap The lower part of the layer 5 is provided with a breath fluid cavity 7, and the interstitial fluid cavity 7 has communication holes 8 communicating with the upper part of the interstitial layer 5. The small volume of breathing liquid cavity 7 is 1 / 5th of inner layer 3 volumes. 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 ...

Embodiment 2

[0035] 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. The breath chamber 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 the contact seam is welded. This also provides a manufacturing method. Breathing liquid chamber 7 has communication hole 8 and communicates with the upper part of interstitial layer 5 . Breathing liquid chamber 7 is a rotating breathing liquid chamber 7 . Both the inflow surface 11 and the outflow surface 12 of the breath liquid chamber 7 are conical surfaces, which facilitate the circulation of cooling water in the breath liquid chamber 7 and 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 ...

Abstract

The invention relates to a thermos cup, and provides a thermos cup which has a simple structure and can serve as both a quick-cooling thermos cup and a double-layer thermos cup, of which the thermal insulation performance is improved and the use is convenient. The thermos cup comprises a cup body and a cup lid, wherein the cup body comprises an inner layer, a shell and a clearance layer between the inner layer and the shell; the shell is provided with a filling-draining hole; and a liquid resting chamber is formed in the lower part of the clearance layer and is provided with a communication hole which is communicated with the upper part of the clearance layer. When the filling-draining hole is blocked, the cup is the double-layer thermos cup. When a small predetermined quantity of cooling water is filled in the clearance layer through the filling-draining hole, the cup is the quick-cooling thermos cup. When the cup serves as the quick-cooling thermos cup, the hot water in the cup can be cooled quickly to be drunk by shaking the cup, so that the urgent need of a thirsty person can be met; and the needs of multiple thirsty persons can also be met because the cup can continuously cool numerous cups of water one by one. The temperature of the shell can be regulated to warm hands by shaking the cup slowly. The cup is simple in structure, convenient to use and is very practical.

Description

technical field [0001] The invention relates to a thermos cup, in particular to a thermos cup with simple structure and improved thermal insulation performance when used as a quick-cooling thermos cup, which 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 thermal ...
