Double-chamber self-oscillation pulse cavitation nozzle

The invention relates to the technical field of water jet cleaning, in particular to a double-cavity self-oscillation pulse cavitation nozzle for automobile cleaning. Comprising a water inlet, a front chamber, a middle runner, a rear chamber and a water outlet, the front chamber is a circular truncated cone-shaped sunken cylindrical cavity, the water inlet is communicated with the cylindrical bottom surface of the front chamber, the sunken part on the other side of the front chamber is communicated with the rear chamber through the middle flow channel, two annular hollow triangles are mounted on two sides of the middle flow channel, and the other side of the rear chamber is communicated with the water outlet. By means of the unique structural characteristics and combination mode of the double chambers, an excellent energy gathering space is provided, the cavitation bubble generation environment is optimized, the space utilization rate is increased, the structure is simple and easy to disassemble, energy conse
