Vacuum cup capable of cooling and heating instantly

Abstract

The invention relates to a vacuum cup capable of cooling and heating instantly, which is convenient in use, wherein air-cooling and air-heating speed of drinking water in the cup can be regulated in a stepless manner. The vacuum cup capable of cooling and heating instantly comprises a cup body and a cup cover, the cup body comprises an inner layer, a shell and a gap layer, the gap layer is arranged outside the inner layer and inside the shell, a bottom hole is arranged at the bottom of the cup body and is communicated with the bottom of the gap layer, an upper hole is arranged at a high position of the shell and is communicated with a high position of the gap layer, a ventilating notch or an air vent is arranged on a skirt, which is lower than the bottom hole, of the shell, the shell is provided with a concave bottom, the bottom hole is arranged on the concave bottom of the shell and provided with a bottom hole cover or a bottom hole switch, and the upper hole is provided with an upper hole switch. The vacuum cup can realize air cooling and air heating for the drinking water in the cup, the air-cooling or air-heating speed of the drinking water in the cup can be regulated in the stepless manner, the drinking water in the cup can be in water cooling or water heating rapidly, a thirsty person can drink the drinking water at the proper temperature rapidly, and furthermore, the vacuum cup can brew good tea and heat milk, and is convenient in use.

Description

technical field [0001] The invention relates to a thermos cup, in particular to a thermos cup capable of rapid cooling and rapid heating. 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) in the outer outer shell of the inner layer. 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 insulation material. The air in the gap layer of the double-layer thermos cup is drawn out to form a vacuum, and this thermos cup is a vacuum thermos cup. The vacuum insulation of ...

Problems solved by technology

Therefore, this kind of cup is inconvenient to be cooled under the tap or through other containers

Of course, this kind of cup is also inconvenient to fill hot water and drink water in the instant hot cup

It is inconvenient to pour water into the cup to cool or heat drinking water in the cup, and it is also because the shell has no bottom surface, thereby forming an intermittent annular opening on the side, which makes it inconvenient to pour water into the cup cavity.

[0005] 2. The air cooling or air heating speed cannot be adjusted steplessly: both the sealing cover and the sealing ring belong to the cover, and both can only be opened and closed. The air flow cannot be adjusted, and the air cooling or air heating speed cannot be adjusted steplessly.

[0006] This thermos cup with a heat dissipation inner cylinder is exactly a kind of double-layer thermos cup, which is a kind of thermos cup capable of rapid cooling and rapid heating. (equivalent to the cavity) is connected at the bottom, and the upper part of the shell is provided with an upper hole (that is, the hole closed by the sealing ring), and the upper hole is connected with the higher part of the gap layer. The ventilation gap is the ventilation gap on the lower skirt of the shell than the bottom hole. This kind of thermos cup is inconvenient to use and cannot adjust the heating speed of air-cooling and air-conditioning steplessly, so it is difficult to popularize and apply.
