The negative ion generator 5 increases negative ion components in the air by using high-voltage corona, thereby improving the air quality and promoting the body health of a user. The multiple sensors comprise a voice receiver 9, a heat sensing probe 10, a light smoke sensing device 11, a gas leakage sensing device 12 and an infrared human body sensing device 13. The user gives an instruction to the cigarette making machine through the voice receiver 9, and the cigarette making machine starts a corresponding mode after receiving the instruction. The temperature sensor in the thermal sensing probe 10 senses that the temperature of the stove reaches the lower limit temperature, automatically starts, and displays the temperature of the probe at the moment through the display screen 4; when the temperature reaches the limit temperature, an alarm signal is sent out. When the light smoke sensing device 11 senses smoke, the cigarette machine is automatically started. When the gas leakage sensing device 12 detects gas leakage, an alarm is given out, and the range hood is automatically started. When the infrared human body sensing device 13 detects that a human body approaches, the cigarette making machine is started; when the cooking machine leaves for more than a specified time, the motor of the range hood is converted into a small rotating speed.
