Description

Smart Tumbler

The present invention relates to a smart tumbler, and more particularly, to a smart tumbler having the convenience of heating or cooling a drink inside the tumbler and having the inside drink well mixed.

Today, tumblers are widely used to store and drink various beverages, juices, coffee and cold / hot water, as well as Chinese medicine or other liquid foods. Since tumblers are mostly provided with lids, they have better heat retention and portability than ordinary cups and disposable containers.

This tumbler has a relatively large capacity to drink a large amount of beverage over a long time, and has been widely used in various sports and leisure activities such as hiking and camping along with a thermos.

In recent years, environmental movements such as restricting the use of disposable paper cups by companies or organizations and establishing rules to use personal mugs are intensifying, and the consumption of tumblers is increasing day by day.

Unlike the thermos or mug, the tumbler has light weight and large capacity, so it is not only portable, but also has excellent heat retention due to its double or vacuum insulation structure, and it has both storage and cleanliness with an openable lid.

In particular, the colorful design is rapidly emerging as a fashion item such as a bag or handbag.

In particular, in recent years, tumblers are used to reduce the use of disposable cups in take-out coffee shops, and their use is gradually increasing in order to store and drink beverages at home or office for a long time.

Therefore, the tumbler has been widely distributed according to the recommendation of the use of individual cups for reducing hygiene and reducing the environmental burden of using the disposable cups.

In the case of a tumbler, it is often provided for carrying, and thus, the warming or cooling of the internal beverage is an important factor.

In general, when a hot beverage is put into the inside of a tumbler with an insulated structure, the temperature is maintained for a certain period of time, and even when a cold beverage is added, the temperature is maintained for a certain time by the insulated structure.

However, a certain period of time is short, and the heat preservation and cooling due to the heat insulation structure is maintained only for a short time, and there is a problem that its effect is deteriorated with the passage of time.

In addition, when the tumbler is used, agitation may be difficult when the contents need to be agitated and drink due to the internal structure, or the contents settled therein may not be completely stirred, resulting in a problem of difficulty in drinking.

Currently, the use of smart devices including smart phones and smart pads is widely spread, and most people of all ages, men and women, use such mobile devices. In particular, in recent years, the use of smart devices that provide large screens and fast data processing is rapidly increasing. Accordingly, various types of batteries have been developed for power supply of smart devices.

However, as the above-described large-screen, high-definition, and high-performance processors are employed in smart devices, the battery consumption of large-sized smart devices is rapidly discharged compared to conventional portable devices. In particular, when the smart device cannot be used due to the complete discharge of the battery in an urgent situation, users are placed in a very uncomfortable situation.

To solve this problem, users may carry additional batteries or carry a secondary battery. The auxiliary battery is a device that incorporates a rechargeable battery and charges a battery such as a smartphone or electronic device with the built-in battery.

Therefore, users have the inconvenience of always carrying various devices such as an auxiliary battery or a charging cradle in preparation for the discharge of a smart device in a travel or other situation.

Accordingly, there is a need to develop a method capable of solving the problem of battery shortage in modern people, while maintaining the effect of keeping and cooling for a long time while maintaining the advantages of a tumbler having portability and practicality, and also being able to properly agitate the internal beverage.

As shown in Table 2 above, as a result of forming the coating layer on the substrate and evaluating the appearance, it was confirmed that the viscosity was measured differently according to the content range of the coating composition and showed a large difference in whether a uniform coating layer was formed according to the viscosity range.

[Experimental Example 2: Evaluation of heat dissipation properties]

In order to confirm the heat dissipation characteristics, Al6061, which is an Al plate (40 mm × 40 mm, t = 10 mm), was used as a material for the specimen. The coating composition prepared in BB1 to BB6 was evenly applied to the Al plate and cured and dried at 50 ° C for 2 hours to prepare a coating film.

In order to compare the effect of the heat dissipation coating layer, the heat dissipation temperature measurement of the Al plate without coating the surface under the same conditions was simultaneously carried out and is shown in Table 3. In the process of measuring the heat dissipation temperature, it was conducted in an enclosed space to prevent changes in convection. Here, T1 refers to a medium that generates heat in the role of a light source unit, T2 is a heat conduction through which heat generated in T1 is transferred, and T3 is a heat dissipation temperature in which the conducted heat radiates from T2 to the atmosphere.
