[0030] like Figure 1-Figure 3 As shown, the pipeline assembly 100 for delivering cleaning liquid according to an embodiment of the utility model includes: a pipeline body 1 and an air supply structure 2.

[0031] A lumen 11 is formed in the pipeline main body 1, and the pipeline main body 1 is provided with a water inlet 12, a liquid inlet 14 and a water outlet 15 which are distributed in sequence along the extension direction of the lumen 11, and a water inlet control valve 16 is provided between the water inlet 12 and the liquid inlet 14. The air replenishing structure 2 is connected to the pipeline main body 1, and the air replenishing structure 2 is located between the water inlet control valve 16 and the liquid inlet 14. The air replenishing structure 2 forms an air replenishing flow channel 23 connected to the lumen 11, and a first one-way valve 24 and a leak-stopping assembly are provided in the air replenishing flow channel 23, and the first one-way valve 24 and the leak-stopping assembly are both configured to be unidirectionally conducted along the air replenishing flow channel 23 to the lumen 11.

[0033] Specifically, the pipeline assembly 100 for delivering the cleaning liquid is provided with a pipeline body 1, one end of the pipeline body 1 can be connected to a faucet, and the other end can be connected to a cleaning device, and water can flow from the faucet into the cleaning device through the pipeline body 1, thereby bringing the cleaning liquid in the pipeline into the cleaning device, and a lumen 11 is formed in the pipeline body 1, and the pipeline body 1 can be set as a cylinder, and the lumen 11 can also be set as a cylindrical lumen 11, thereby reducing the energy loss of water when flowing in the lumen 11, and the pipeline body 1 is provided with an extension direction along the lumen 11. The water inlet 12, the liquid inlet 14 and the water outlet 15 are distributed in sequence. The water inlet 12 can be connected to a faucet, and the water outlet 15 can be connected to a cleaning device. The liquid inlet 14 is arranged between the water inlet 12 and the water outlet 15. The liquid inlet 14 can put cleaning liquid into the tube cavity 11. When water flows into the tube cavity 11 from the water inlet 12 and flows to the liquid inlet 14, the cleaning liquid in the tube cavity 11 can be driven to flow, and then can flow from the water outlet 15 to the cleaning device, thereby realizing automatic delivery, saving manpower and improving cleaning efficiency.

[0034] Furthermore, a water inlet control valve 16 is provided between the water inlet 12 and the liquid inlet port 14.

The air replenishing structure 2 is arranged between the water inlet control valve 16 and the liquid inlet port 14, and the air replenishing structure 2 forms an air replenishing flow channel 23 connected to the tube cavity 11. When the water inlet control valve 16 controls the water flow to flow into the tube cavity 11, the water flow can flow into the cleaning equipment , and when the water inlet control valve 16 disconnects the connection between the pipeline main body 1 and the faucet, part of the water flow can rush into the cleaning equipment under the action of inertia. The air-injection structure 2 is provided to avoid the generation of negative pressure in the tube cavity 11, thereby improving the sealing performance of the pipeline main body 1, and a first one-way valve 24 and a leak-proof component are provided in the air-injection flow channel 23. The first one-way valve 24 and the leak-proof component are both configured to be unidirectionally conducted along the air-injection flow channel 23 to the tube cavity 11, so that external gas can pass into the tube cavity 11 through the air-injection flow channel 23, and at the same time, the water flow in the tube cavity 11 can be prevented from flowing to the outside through the air-injection flow channel 23, thereby preventing the air-injection structure 2 from leaking and improving the sealing performance of the pipeline.

[0035] Among them, it should be noted that although the first one-way valve 24 can realize the one-way introduction of airflow at the air replenishing structure 2, there is still a risk of water seepage at the first one-way valve 24 under the extremely low pressure of 0 to 0.02 MPa. In the utility model, by simultaneously providing the leak-stop component and the first one-way valve 24, the sealing performance of the air replenishing structure 2 can be more effectively improved, the risk of water seepage under the extremely low pressure of 0 to 0.02 MPa can be reduced, and the reliability of the pipeline assembly 100 can be improved.
