The invention relates to an atomizing type range hood with a water tank. The atomizing type range hood comprises a hollow range hood box, an atomizing water collecting and oil contamination cleaning box and a high-pressure water pump. Two ends of the hollow range hood box are communicated, the hollow range hood box, the atomizing water collecting and oil contamination cleaning box and the high-pressure water pump are communicated with each other via a recycling tube and a water pumping tube respectively, an atomizing tube component connected with the high-pressure water pump and filter screens which are distributed in an arrayed manner are arranged in the range hood box, lampblack and dust particles in kitchen waste gas are effectively absorbed and filtered, a removal effect is good, exhausted gas is cleaner, waste gas in kitchens of restaurants and hotels can be exhausted fundamentally, and the environment of the earth is protected; an automatic water inlet device and a timing water inlet device automatically fill water in the atomizing water collecting and oil contamination cleaning box, reliability is good, internal oil contamination can be discharged in time, and blockage of a nozzle is prevented effectively; and moreover, the integral atomizing water collecting and oil contamination cleaning box is adopted, so that the atomizing type range hood with the water tank is simple in structure, low in manufacturing cost, easier and more convenient in installation and repair, can recycle atomizing water, and is saving and environment-friendly.
