Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The structure of the multifunctional solar refrigeration backpack is shown in figure 1, and the backpack comprises a backpack body, straps 1, a power supply mechanism, a refrigeration mechanism, an anti-theft mechanism and a GPS tracker.

The backpack main body is waist drum form, and the knapsack body includes back 3 and front 2, is equipped with the zip fastener 4 that is used for the knapsack to open and shut on the knapsack top, is equipped with pull head 5 on the zip fastener.

The power supply mechanism comprises a solar cell panel 6, an inverter and a storage battery, wherein the inverter adopts an independent power supply, a sine wave inverter and a transformerless inverter. The solar panel 6 is fixed on the front face 2. The solar cell panel 6 is electrically connected to the battery through an inverter. The backpack supplies power to all electronic components on the backpack through solar power generation, is green and environment-friendly, and saves electric energy.

The refrigerating device comprises a refrigerating controller, a temperature sensor 7, an interlayer 10, a fan control switch 9, a semiconductor refrigerating sheet 8 and a refrigerating switch, wherein the number of the semiconductor refrigerating sheets 8 is 2, and the refrigerating controller adopts an AT89C52 singlechip. The interlayer is made of aluminum, as shown in fig. 4 and 5, the interlayer 10 is square, two sides of the interlayer 10 are hollowed, the fan 11 is fixedly installed in the interlayer 10, the two semiconductor refrigerating pieces 8 are symmetrically installed in the interlayer 10 and located on two sides of the fan, and the two semiconductor refrigerating pieces 8 are respectively close to two hollowed sides of the interlayer 10. The interlayer 10 is fixedly arranged at the inner side of the back face 3, and the two hollowed-out sides of the interlayer 10 are close to the two sides of the backpack body. As shown in fig. 2, the temperature sensor 7 and the fan control switch 9 are mounted on the back surface. The temperature sensor, the refrigeration controller and the refrigeration switch are electrically connected in sequence, and the refrigeration switch is electrically connected with the two semiconductor refrigeration pieces. When the temperature sensor detects that the external environment temperature is more than or equal to 30 ℃, the refrigeration controller controls the switch to be closed, the semiconductor refrigeration piece works, and refrigeration is started.
