In addition, the timing unit 600 starts timing while the first ventilation unit 410 and the second ventilation unit 510 start working, and sends the working time length data of the first ventilation unit 410 and the second ventilation unit 510 to the control unit 100, the control unit 100 controls the working states of the first ventilation unit 410 and the second ventilation unit 510 according to the working time length data, when the working time length is longer than the preset time length, the control unit 100 controls the first ventilation unit 410 and the second ventilation unit 510 to stop working, and when the temperature data in the first air duct 400 reaches the preset refrigeration threshold again, the cycle is started.
Hot air circulation mode: the temperature adjusting unit 300 is started, a cold area is formed in the first air duct 400, a hot area is formed in the second air duct 500, the second temperature sensor 520 acquires temperature data in the second air duct 500 and sends the temperature data to the control unit 100, the control unit 100 compares the temperature data in the second air duct 500 with a preset heating threshold, when the temperature data in the second air duct 500 reaches the preset heating threshold, the control unit 100 controls the first ventilation unit 410 to establish air flow from a child sitting area to an external environment area, the second ventilation unit 510 establishes air flow from the external environment area to the child sitting area, and a circulating air flow from the second air duct 500-child sitting area-first air duct 400-external environment area flowing direction is formed, so that hot air in the second air duct 500 is sent to the child sitting area, cold air in the child sitting area is discharged to the external environment area, and heating of the child sitting area is achieved.
