It should be noted that, based on the above technical solutions, the on-demand quick-cooling thermos cup provided by the present invention mainly includes an outer bladder, an inner bladder, an outer cover, an inner lid, a bottom seal and a central push rod, and the inner bladder is used for the insulation layer. It is used to store hot water. Through the movement of the center push rod, the hot water in the inner tank can flow into the gap between the inner tank and the outer tank, so as to achieve rapid cooling, and the inner cover and the outer cover can be taken out independently to meet drinking water requirements. And the different needs of adding water, the overall structure is in the form of detachable assembly.

According to the present invention, the temperature of the hot water can be lowered to a temperature suitable for drinking on demand according to the demand of the user, and the effect of warming hands can be achieved when the temperature is lowered.

In order to understand the technical solutions of the present invention more clearly, the working principle of the present invention is described below.

For the on-demand quick-cooling thermos cup provided by the present invention, after the assembly is completed, the inner cover 4 can be taken out independently, hot water is added into the inner tank 2, and the inner cover 4 is covered after the water is added. At this time, the central push rod 6 is at The spring 504 of the bottom seal 5 acts downward. Block the conical hole 201 at the bottom of the inner pot 2, so that the hot water is kept warm in the inner pot 2;

When you need to drink water or warm your hands, press the pressing plate 404 on the inner cover 4 to drive the pressing upper rod 401 and the pressing lower rod 402 to move down, and push the central push rod 6 to move down after overcoming the upward force of the spring 504. The hot water in 2 flows into the gap between the inner tank 2, the outer tank 1 and the bottom seal 5 through the gap of the conical hole 201, and then, through the outer tank 1 and the bottom seal 5, it conducts rapid heat exchange with the outside world to achieve temperature. At this time, the temperature of the outer bladder 1 can be used to warm hands. At this time, the hot water in the gap between the inner bladder 2, the outer bladder 1 and the bottom seal 5 can be cooled by opening the outer cover 3. , let people pour out and drink.

After releasing the pressing plate 404, the central push rod 6 will move upward under the force of the spring 504, and re-block the conical hole 201 of the inner pot 2, and the water discharge is completed. At this time, the inner pot 2 and the outer pot 1 The temperature of the water in between is slowly decreasing. If you want to cool down quickly, you can turn the thermos upside down as a whole to increase the heat exchange area. After the water temperature is suitable, unscrew the outer cover 3 separately, and you can drink it. At the same time, the inner cover 4 always covers the inner tank 2. to avoid the heat dissipation of the hot water in the inner tank 2 when drinking water.

To sum up, compared with the prior art, the invention provides an on-demand quick-cooling thermos cup, which has a scientific structure design, can cool down according to the amount of water people drink in a single time, and ensure that the rest of the water is still at a high temperature. It is convenient for people's daily work and life, and has great production and practical significance.

In addition, the use season of the thermos cup is mostly the season when the temperature is low, and the thermos cup of the present invention can also be used to warm hands with the heat released when the hot water cools down.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
