• wherein the pipeline assembly (1) comprises a connecting component (2), a dispersion pipeline (3), and a flow pipeline (4);
• wherein the connecting component (2) is connected to one end of the flow pipeline (4), and the other end of the flow pipeline (4) is configured for connecting to a connecting component (2) of another pipeline assembly (1);
• an inner diameter of the dispersion pipeline (3) gradually changes from small to large, and the dispersion pipeline comprises a small port and a large port, and an inner diameter of the small port is smaller than an inner diameter of the large port;
• the dispersion pipeline (3) comprises a hose, which is located inside the flow pipeline (4);
• an inner diameter of the flow pipeline (4) remains unchanged;
• the large port is arranged on an inner wall of the flow pipeline (4) and communicates with an inside of the flow pipeline (4);
• the small port is arranged close to the connecting component (2), and the dispersion pipeline (3) is wrapped with a vibration-reducing component (5) outside;
• wherein a fluid flows in the pipeline assembly (1) from the connecting component (2) to the dispersion pipeline (3);
• wherein the dispersion pipeline (3) comprises a deflection portion (31) and a guide portion (32), and the deflection portion (31) is connected to the guide portion (32), and the deflection portion and the guide portion are communicated with each other;
• wherein with reference to a flow direction of the fluid, the deflection portion (31) is located upstream of the guide portion (32), the deflection portion (31) is configured for changing an original flow direction of the fluid, the guide portion (32) comprises the small port and the large port, and the deflection portion (31) is the hose;
• wherein the deflection portion (31) is a cylinder or a polygonal prism, and a plurality of channels (33) are arranged inside the deflection portion (31), and the plurality of channels (33) are arranged around a central axis of the deflection portion (31), and the channels (33) are inclined relative to a central axis of the flow pipeline (4) in which they are located.
