The invention provides a vertical take-off and landing type dehazing aircraft which comprises four lift units, a second electric cylinder, two sliding blocks, two first electric cylinders, an electrical control device, a machine body, an oil tank, a water pump, a water tank and four water sprayers. The vertical take-off and landing type dehazing aircraft is characterized in that the machine body is of a rectangular flat plate structure, and the two sides of the flat plate are provided with two square grooves. Every two of the four lift units are symmetrically arranged on the two sides of the machine body. Each lift unit comprises a turbofan engine, a servo motor, a sliding rod, a sleeve, a crank and a pin shaft. The sleeve is made of a hollow square pipe, and one end of the inner side of the sleeve is hinged into the square groove of the machine body through the pin shaft. The vertical take-off and landing type dehazing aircraft is provided with the four lift units capable of being controlled independently, so that the aircraft has vertical take-off and landing capabilities; when the aircraft is encountered with unstable air flow, the sliding rod can extend out through the second electric cylinder, so that the length and width of the whole aircraft are increased, and the stability of the aircraft is improved.
