The fan for simulating natural wind according to the present invention includes a fan body with a head-shaking motor, a
fan blade rotation motor and a watering can device; and a
control unit including a
user control board, a controller, a temperature and
humidity sensor and a pyroelectric
infrared sensor, wherein, The temperature and
humidity sensor, pyroelectric
infrared sensor, and watering can device are respectively connected to the controller by communication. The controller stores a number of comfortable natural
wind speed samples collected in different regions and under different environmental conditions. When the
ambient humidity measured by the temperature and
humidity sensor When it is lower than the set value in the controller, the controller controls the watering can device to spray to adjust the
ambient humidity. The controller receives the current temperature and humidity
signal from the temperature and humidity sensor, the heat source position
signal from the pyroelectric
infrared sensor and After the heat source temperature
signal is processed, the corresponding natural wind sample signal is obtained from the memory to control the shaking head motor to swing to the heat source with a predetermined range, so as to achieve the effect of simulating natural wind and saving energy.
