The specific pipeline connection method is as follows Figure 1 and Fig.35 shown.

[0075] In a specific embodiment, the pipe joint assembly 40 includes a first joint 41 installed on the washing pipeline 121 and a second joint 42 installed on the injection pipeline 122; the first joint 41 and the second joint 42 are both three-way structures; the two pipes of the first joint 41 are water inlets, and one pipe is a water outlet; the two pipes of the second joint 42 are water outlets, and one pipe is a water inlet; a water inlet of the first joint 41 is connected to a water outlet of the second joint 42. During specific use, the water flow velocity of the washing pipeline 121 is high and the flow rate is small, while the water flow velocity of the injection pipeline 122 is low and the flow rate is large. After the washing pipeline 121 and the injection pipeline 122 are connected through the pipe joint assembly 40, the pressure difference generated by the difference in fluid flow rates can be used to make the water flow of the injection pipeline 122 assist the washing pipeline 121 to flush the toilet, so as to increase the flushing flow rate of the washing nozzle at the end of the washing pipeline, thereby greatly improving the washing effect of the toilet, avoiding the problem of repeated flushing to achieve complete sewage discharge, improving the efficiency of water resource utilization, and being beneficial to water saving and environmental protection.

[0076] In a more specific embodiment, the water flow rates of the two water outlets of the second joint 42 are not equal, wherein the water outlet with a smaller water flow rate is connected to one of the water inlets of the first joint 41. Specifically, the cross-sectional areas of the two water outlets of the second joint 42 are not equal, wherein the water outlet with a smaller cross-sectional area is connected to one of the water inlets of the first joint 41. Among them, the inner diameter of the water outlet with a smaller cross-sectional area in the second joint 42 can be set to be 0.2-0.5 times the inner diameter of the larger water outlet. Specifically, by setting the water flow rates of the two water outlets of the second joint 42 to be unequal, in order to reduce the influence of the water flow rate of the second joint 42 on the corresponding injection pipeline 122 for injection, the water outlet with a smaller water flow rate can be connected to the first joint 41. Specifically, in order to adjust the water flow of the two water outlets in the second joint 42 and connect the water outlet with a smaller water flow to the first joint 41, a water outlet with a smaller cross-sectional area can be set to communicate with the first joint 41. In actual application, adjusting the cross-sectional area of ​​the water outlet is only one way to adjust the water flow of the water outlet.
