The air outlet is connected to the rear air pipe through a hose; the integrated control module is installed on the inside of the door panel, and is connected to the indoor unit and the outdoor The machine and the air duct switcher are connected to control their work; the outer side of the door panel is provided with an LED display.

The outdoor unit includes a solar panel, a black aluminum heat-absorbing plate, an outdoor unit body, and an air duct; the solar panel and the black aluminum heat-absorbing plate are installed outside the outdoor unit body; the air duct is arranged on the side of the outdoor unit body; The pipe is connected with the solar air inlet of the air duct switcher through a hose.

The integrated control module includes the power control board, LCD display control board, high-voltage circuit, and air duct switching control module; the LCD display control board, high-voltage circuit, indoor unit, and air duct switching control module are all connected to the power control board; The control board is connected to supply the electric energy converted from solar energy to the power control board; the LCD display control board is used to control the LED display; the air duct switch control module is connected to the air duct switcher to control the work of the air duct switcher; the electrostatic box and the high voltage circuit connect.

The air channel switching control module includes a solar heat collection channel control module and a natural air channel control module.

The beneficial effect of the solar fresh air blower of the present invention is that solar power can be used to drive the air purifier to work, the solar heat collector can heat the air, and then use the electrostatic box to remove dust and remove impurities and pollution in the outdoor air, so as to realize double heating and filtering of the air entering the home.
