[0020] The following will describe the specific embodiments of the present utility model with reference to the accompanying drawings.

[0021] Please refer to Figure 1-6 , the present utility model discloses an efficient bubble cleaning spray head device. As shown in the figure: It includes a main pipe with both ends closed and having a water inlet 1 in the middle. The inside of the main pipe is a cavity 2. The main pipe is provided with a plurality of water outlets along its length direction. Each water outlet is provided with a spherical plain bearing 3, and each spherical plain bearing 3 is provided with a Venturi tube-shaped water outlet 4 with its inner end communicating with the cavity 2.

[0022] As a preferred mode, both ends of the main pipe are closed by covers 5, and the connection mode can be welding.

[0023] In the present utility model, the water inlet 1 is provided with a threaded connection structure 11, and the main pipe and the high-pressure water pump can be rotationally connected through the threaded connection structure 11. As Figure 2 , 7 , 8 shows, the high-pressure water pump is rotationally connected to the threaded connection structure 11 of the water inlet 1 through a rotary joint. There is a rotary bearing between the connection part (such as the threaded connection part at the lower end) of the rotary joint and the housing, which can realize the revolution of the main pipe.

[0024] In the present utility model, as Figure 3 , 4, the Venturi tube-shaped water outlet 4 is composed of an inlet pipe section 41, a contraction section 42, a throat pipe section 43, and a diffusion section 44 in sequence from the inner end to the outer end; the Venturi tube-shaped water outlet 4 is fixed in the spherical plain bearing 3 through the inlet pipe section 41. When the cleaning liquid enters the Venturi tube-shaped water outlet 4 from the inlet pipe section 41, after passing through the contraction section 42 and the throat pipe section 43, a hydrodynamic cavitation phenomenon will occur in the diffusion section 44, releasing huge energy and generating microjets with high flow velocity and strong impact force, which can well clean the food-grade stainless steel patterned plate components.

[0025] In the present utility model, as Figure 5 , 6 , the spherical plain bearing 3 includes a fixed outer ring 31 and a movable inner ring 32 rotatably arranged within the fixed outer ring 31.

[0026] When the present utility model is in use, the high-pressure water flow flowing out from the high-pressure water pump reaches the cavity 2 of the main pipe and will drive the main pipe to revolve around the water inlet. Then, when the high-pressure water flow passes through the spherical plain bearing 3 and is discharged from the Venturi tube-shaped water outlet 4, it will drive the Venturi tube-shaped water outlet 4 to rotate relative to each water outlet. Under the secondary acceleration of revolution and rotation, each water outlet can perform multi-angle flying flushing, and even the gaps formed by the stacking of the corners of the cleaning equipment and various patterned plate components can be "cleaned without dead corners". In addition, when the water flow passes through the Venturi tube-shaped water outlet 4, a hydrodynamic cavitation phenomenon will occur in the diffusion section 41. The lifespan of the bubbles is relatively short. When they suddenly collapse, they release huge energy and generate microjets with high flow velocity and strong impact force, which can well clean the food-grade stainless steel patterned plate components.

[0027] In summary, the above is only the preferred embodiment of the present utility model, and is not intended to limit the scope of implementation of the present utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present utility model should fall within the technical scope of the present utility model.
