Magnetically sealed double-body vacuum cup

Abstract

The invention discloses a magnetically sealed double-body thermos cup. There is a central hole at the bottom of the upper cup, and a heat insulation plate is placed at the bottom of the upper cup body. There is a through hole in the center that is smaller than the bottom hole of the cup. The weight is a cylindrical magnetic conductive metal. pieces. The suction part is formed by a magnetic ring and a weight. The magnetic ring is a magnetic ring whose inner diameter is the same as that of the through hole of the heat shield, and is connected to the center of the heat shield. The magnetic adjustment pad is connected under the weight, and there is a heat insulation layer under the weight. The guide device is composed of a cap and a column, which guide and limit the movement of the weight. The lower end of the column is connected to the periphery of the bottom hole of the upper cup, and the upper end is connected to the cap. The cap acts as a limit to the falling of the weight, buffering Pad cushions the impact of the weight on the guide. The impact shield is located below the through hole in the heat shield. The thermos cup is turned upside down, the weight falls to make hot water flow into the upper cup, the thermos cup is placed upright, the weight falls, and under the action of the magnetic force, the weight presses the magnetic adjustment pad to seal the water. The invention has novel principle, simple structure and convenient use.

Description

Technical field [0001] The invention relates to a daily necessities, in particular to a thermos cup which can quickly cool part of hot water with a magnetic material sealing a water passage. Background technique [0002] The thermos cup is a common daily product in people's lives. Its function is to keep the hot water at the temperature, but it often causes the inconvenience that the water temperature is too high when drinking water. To solve this problem, some solutions have appeared. [0003] For example, the Chinese patent "Insulation Cup capable of rapid temperature change" with publication number CN202801040U and the Chinese patent "Multi-purpose Insulation Cup" with publication number 103584639A can achieve rapid cooling, but the first method can only cool the whole cup of water. In the second method, although partial cooling can be achieved, the lid and cold water cup must be unscrewed at the same time each time you drink water, which is inconvenient to use and the opening o...

Problems solved by technology

[0002] Thermos cups are common daily necessities in people's lives. Its function is to keep hot water warm, but it often causes the inconvenience that the water temperature will be too high when drinking water is needed. In order to solve this problem, some solutions have emerged

[0003] For example, the Chinese patent "insulation cup capable of rapidly changing temperature" with the publication number CN202801040U and the Chinese patent "multipurpose insulation cup" with the publication number 103584639A can realize rapid cooling, but the first method can only cool the whole glass of water

The second way, although partial cooling can be achieved, but every time you drink water, you have to unscrew the lid and the cold water cup at the same time, which is inconvenient to use and the opening of the cooling cup affects the heat preservation

However, the disadvantages of this method of setting the channel switch on the side wall of the bottle body are: 1. The switch is arranged on the side wall of the bottle body, which destroys the integrity of the bottle body as a container, resulting in difficulties in manufacturing, and the switch is located in a water area. It is easy to cause water seepage and has high sealing requirements for switches

2. When using the switch, the hand must be placed in an operable position, which is very inconvenient to use

4. The body of the cup is usually taken by hand, and the switch is set on the side wall to prevent the hand from taking the cup, causing inconvenience

But its switch structure is complicated, and the method of setting the button outside the cup body increases the difficulty of sealing and the corresponding structure, and the water switch must be pressed every time it is used
