Abstract

A solar heating cup is a solar cup for heating water or other liquids. A solar absorbing coating is also attached to the inner and outer walls of the double-layer transparent vacuum cup structure. After the solar energy is converted into heat energy, it is transferred to the water inside the cup, so that hot water can be obtained economically, environmentally friendly and conveniently.

Description

solar mug

Technical field

The utility model relates to a solar cup which can use solar energy to heat water or other liquids.

Background technique

Although present cups are of various shapes, all can't actively heat water, but can only keep warm passively, can't get hot water when there is no heating equipment. On the other hand, the development, utilization and environmental protection requirements of new energy have become a trend, especially the inexhaustible, clean and environmentally friendly solar energy has been paid more and more attention and utilization. At the same time, the development of solar absorbing coatings has been quite mature, and has been widely used in vacuum heat collectors and the like.

Contents of the invention

In order to make full use of solar energy and obtain hot water more conveniently, the utility model provides a solar cup, which can absorb solar radiation energy to heat and keep water or other liquids in the cup.

The technical solution adopted by the utility model to solve the technical problem is: a solar cup, which includes an inner layer material, a vacuum layer, and an outer layer material from the inside to the outside, and both the inner layer material and the outer layer material are transparent materials. In that, the outer wall of the inner layer material is also attached with a solar absorbing coating. In this way, the solar radiation energy can be effectively absorbed to heat and keep warm water or other liquids.

The beneficial effect of the utility model is that it can conveniently use sunlight to obtain hot water without any other heating equipment, and the utility model has a simple structure, is convenient to use, and saves energy at the same time.

Detailed ways

Implementation mode 1:

A solar cup comprises an inner layer material 4, a vacuum layer 2, and an outer layer material 1 from the inside to the outside, and the inner layer material 4 and the outer layer material 5 are both transparent glass materials. A solar absorbing coating 3 is also attached to the outer wall of the inner layer material 4 . The solar absorbing coating 3 here can adopt AL-N/AL selective absorbing coating and the like. The solar absorbing coating 3 absorbs solar radiation energy, converts the absorbed solar energy into heat energy and transfers the heat to water or other liquids in the cup through the heat conduction of the inner layer material 4, thereby playing the role of heating and heat preservation. The vacuum layer 2 between the inner layer material 4 and the outer layer material 1 can reduce heat conduction and convection, thereby reducing heat loss.

Claims (1)

1. A solar cup, comprising an inner layer material (4), a vacuum layer (2), and an outer layer material (1) from the inside to the outside, and both the inner layer material (4) and the outer layer material (1) are transparent materials , characterized in that: a solar absorbing coating (3) is also attached to the outer wall of the inner layer material (4).
