Abstract

The invention discloses a self-driven type fast-cooling water cup based on temperature-difference power generation. The self-driven type fast-cooling water cup comprises a cup body, a cup cover, a semiconductor temperature-difference power generation module, a water temperature detection display module, a heat exchange module, a driving module, a power source module, a first circuit control panel, a second circuit control panel and a control button; the semiconductor temperature-difference power generation module and the first circuit control panel are both placed in an annular cavity of the cup body; the power source module, the driving module and the second circuit control panel are electrically connected and all placed in a mounting cavity of the cup cover; by switching on charging interfaces located in the first circuit control panel and the second circuit control panel, electric energy generated by the semiconductor temperature-difference power generation module is stored into the power source module to supply electricity to a motor for driving the heat exchange module to rotate; and the control button controls the motor to be started and stopped. Temperature-different power generation is conducted through a semiconductor, the motor is driven to drive the heat exchange module to rotate, heat exchange between water and the heat exchange module is enhanced, hot water is rapidly cooled through heat storage and release of a phase change material in the heat exchange module, and the constant water temperature can be maintained.

Description

technical field [0001] The invention belongs to the field of quick-cooling water cups, in particular to a self-driven quick-cooling water cup based on temperature difference power generation. Background technique [0002] At present, there are 55°C cups that use a heat exchange device in the water cup to cool hot water in the market. It mainly uses the phase change material filled in the cup wall to cool the hot water, but it is bulky, not portable and cannot be disassembled. Artificial shaking is required to accelerate heat transfer, so the scope of application of the 55°C cup is limited, and there are certain limitations. [0003] In addition, in view of the advantages of semiconductor thermoelectric power generation modules such as compact structure, high reliability, light weight, and no pollution, some scholars use semiconductor thermoelectric power generation modules in water cups (such as: CN107692737A, CN108784228A, and CN104207588A), and utilize the temperature diff...

AI Technical Summary

Problems solved by technology

The cold end of the semiconductor refrigeration module is attached to the upper end of the cooling block containing the phase change material, and the lower end of the cooling block is in contact with the water, but the contact area is limited, and once the hot water in the cup is reduced, the water can only be ensured by shaking or inverting the cup. In contact with the cooling block, it is difficult to achieve rapid cooling

In addition, the semiconductor refrigeration module in this patent needs to be connected to an external power supply, which is not energy-saving
