1. A cleaning device of a range hood is characterized by comprising:

  • the water pump is used for pumping the cleaning liquid when the water pump is started;

    the heating assembly comprises a liquid storage cavity and a heating element arranged corresponding to the liquid storage cavity, and an inlet of the liquid storage cavity is connected with the water pump;

    the temperature sensor is arranged corresponding to the heating assembly and used for detecting the temperature of the heating assembly;

    the spray pipe is connected with the outlet of the liquid storage cavity;

    the control module is respectively connected with the water pump, the heating assembly and the temperature sensor, and controls the heating assembly to continuously heat when the range hood starts a cleaning program, and controls the water pump to be started for a first preset time and to be stopped for a second preset time in each cleaning period after the temperature of the heating assembly reaches a first preset temperature for the first time so as to realize pulse cleaning on the range hood, wherein when the water pump is started, the cleaning liquid is pumped into the heating assembly to be instantly vaporized and instantly expanded so as to generate a water-vapor mixture with high temperature and high pressure, and the water-vapor mixture is sprayed out from the spray pipe so as to clean the range hood;

    and the pressure relief valve is arranged between the water pump and the inlet of the liquid storage cavity so as to open for pressure relief when the pressure in the liquid storage cavity is greater than a pressure threshold value.
