detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

As shown in Figure 1, the thermos cup of the present utility model includes a cup body 1 and a cup cover 2. The bottom of the cup body 1 is equipped with a first thermoelectric power generation sheet 3, a first micro battery 4 and a heating chip 5. The first thermoelectric power generation The hot end of the sheet 3 is applied on the inner wall 6 of the cup, the cold end of the first thermoelectric sheet 3 is applied on the outer wall 7 of the cup, and the power output end of the first thermoelectric sheet 3 is connected to the first micro-battery 4; the cup body A heating button 13 is installed on the outer wall 7, and the first micro battery 4 is connected to the heating chip 5 through the heating button 13;

The top of the cup cover 2 is equipped with a second thermoelectric power generation sheet 8, a second micro battery 9 and a refrigeration chip 10, the hot end of the second thermoelectric power generation sheet 8 is applied on the inner wall 11 of the cup cover, and the cold end of the second thermoelectric power generation sheet 8 Apply on the outer wall 12 of the cup cover; the second micro-battery 9 is connected to the power output end of the second thermoelectric power generation sheet 8; a cooling button 14 is installed on the outer wall 12 of the cup cover, and the second micro-battery 9 is connected to the cooling chip 10 through the cooling button 14 connected.

Both the first micro-battery 4 and the second micro-battery 9 are 4V4.5Ah polymer lithium batteries, and the external dimensions of the polymer lithium batteries are 65mm×48mm×8mm.

The first thermoelectric generation sheet 3 and the second thermoelectric generation sheet 8 adopt the thermoelectric generation sheet F40550. The temperature resistance of the thermoelectric generator (meaning that the thermoelectric generator can work at a maximum of 200°C) is about 200°C. When the temperature difference is 80°C, it can generate a voltage of about 5.2V and a current of 820mA; when the temperature difference is 60°C It can generate a voltage of about 4.09V and a current of 680mA, which is suitable for power generation of water temperature difference.

The heating chip 5 and the cooling chip 10 adopt TEC1127018 semiconductor thermoelectric cooling chip (produced by Changshan County Wangu Electronic Technology Co., Ltd.). The semiconductor thermoelectric cooling chip has both cooling and heating functions. When the cooling function is needed, Connect the red wire of the chip to positive and the black wire to negative. When you need to use the heating function, connect the red wire of the chip to negative and the black wire to positive. When the power supply battery is a 4V 4.5Ah lithium battery, the heating power of the heating chip 5 is 178W, and the maximum cooling power of the cooling chip 10 is 160W.

When the thermos cup of the utility model is in use: inject boiling water into the cup body 1 and cover the cup cover 2 . Because there is a temperature difference between the hot end and the cold end of the first thermoelectric power generation sheet 3, there is also a temperature difference between the hot end and the cold end of the second thermoelectric power generation sheet 8, and the first thermoelectric power generation sheet 3 and the second thermoelectric power generation sheet 8 respectively convert the heat difference Converted into electric energy, the electric energy converted by the first thermoelectric power generation sheet 3 is sent to the first micro-battery 4 for storage, and the electric energy converted by the second thermoelectric power generation sheet 8 is sent to the second micro-battery 9 for storage. When you need to drink water, unscrew the cup cover 2, pour water into the cup cover 2, if the water temperature is higher, press the cooling button 14, the second micro battery 8 provides power to the cooling chip 9, and the cooling chip 9 starts to refrigerate.
