[0030] With reference to the accompanying drawings, a kitchen water purifying faucet comprises a faucet, an inner body 10 provided in the faucet and capable of flowing waste water, a waste water pipe 11 connected to the lower end of the inner body and connected to a water purifying main machine, a water storage cavity 12 provided above the inner body, the waste water in the waste water pipe being capable of flowing into the water storage cavity from bottom to top, an upper water outlet hole 13 provided at the lower end of the water storage cavity, a transition cavity 14 provided at the inner body below the upper water outlet hole, a water outlet hole 15 provided at the lower end of the transition cavity, and a drain pipe 16 connected to the water outlet hole. An air inlet channel 17 is further provided on the inner body, and the air inlet channel is capable of connecting the atmosphere with the transition cavity. The air outlet of the air inlet channel is located at the upper end of the transition cavity, so that when the water flow is too much, the waste water will not flow out of the air inlet channel, and the phenomenon of water leakage will not occur. In use, the water purifying main machine is provided under the table top, and the faucet is provided on the table top. The waste water of the present application is not directly connected to the sewage pipe (which can also be connected to the household sink drain), but is first flowed upward into the anti-backflow structure on the table top, the water outlet of the upper water outlet hole forms a negative pressure in the transition cavity, the transition cavity is connected to the atmosphere, air is sucked in, the overall water flow in the pipe is saturated, the efficiency of the drain is improved, the hole diameter of the upper water outlet hole can be reduced according to the direction of the water flow, and the hole diameter of the water outlet hole is larger than that of the upper water outlet hole. In this way, when the water purifying main machine is turned off, sudden pressure changes are likely to cause siphoning, and the air inlet channel can prevent the backflow of waste water and prevent pollution of the filter element.

[0031] Preferably, the faucet comprises a base 20 capable of being provided on the table top, a bend pipe 30 provided above the base, and the inner body provided in the base, so that the anti-backflow structure and the faucet are integrated. A pull pipe 40 and a water purifying outlet pipe 50 are provided in the bend pipe, a pull head 61 is provided at the water outlet end of the bend pipe, the pull head is detachably connected to the bend pipe, that is, the pull head can be pulled out for use, a water purifying outlet nozzle 62 is further provided at the water outlet end of the bend pipe, and the water outlet end of the water purifying outlet pipe is capable of being connected to the water purifying outlet nozzle. The water purifying outlet nozzle is fixedly provided at the water outlet end of the bend pipe, that is, the water purifying outlet end is relatively fixed.

[0032] Furthermore, the base also includes a water channel body 21, which is compatible with the water channel body. It also includes a switch valve 22 and a mixing valve 23 that can be connected to the water channel body. The switch valve can be connected to the purified water inlet pipe and purified water outlet pipe to control the output of purified water. The outlet end of the mixing valve can be connected to a pull-out pipe, and the inlet end of the mixing valve can be connected to a cold water pipe and a hot water pipe to control the output of domestic water and adjust the water temperature. The base also has a first handle 24 and a second handle 25. The first handle 24 can be connected to the switch valve, and the second handle 25 can be connected to the mixing valve. These two handles are distributed on both sides of the base. The purified water inlet pipe 51, purified water outlet pipe 50, cold water pipe 71, hot water pipe 72, and pull-out pipe can be plugged into the waterway body. That is to say, a corresponding flow channel is provided in the waterway body. The flow channel connects the inlet pipe and the valve core, and can also connect the outlet end of the valve core with the pull-out pipe and the purified water outlet pipe.

[0033] Furthermore, a water outlet body 60 is provided on the inner circumference of the outlet end of the bend, and the purified water outlet is set on the water outlet body. The pull-out tube can be connected to the pull-out head, and the pull-out head is provided with a pull rod 63. The pull rod can pull the pull-out head out from the bend, and the pull-out head can be inserted into the slot 64 of the water outlet body. One end of the pull rod can extend to the outside of the bend for operation. The pull-out tube includes an inner tube 41 and an outer tube 42. A spring 43 is provided between the inner tube and the outer tube. The spring is sleeved on the outer circumference of the inner tube, which can ensure the rigidity of the pull-out tube and prevent it from bending. The water inlet end of the inner tube can be inserted into the water channel body.

[0034] Compared to ordinary kitchen faucets, this faucet boasts a more advanced design, cleverly integrating a kitchen faucet, a water purifier faucet, and an anti-backflow device into one unit, transforming existing wastewater discharge designs. This not only simplifies installation but also saves space, resulting in a cleaner and more aesthetically pleasing kitchen. Furthermore, the faucet features a retractable pull-out tube, allowing users to easily extend it for flexible operation during use; when not in use, a simple pull retracts it, maintaining a tidy and minimalist kitchen appearance. This design not only enhances usability but also adds a modern and stylish touch to the kitchen.

[0035] An anti-backflow structure is installed at the faucet. The wastewater pipe of the main water purifier system is connected to the inlet of the anti-backflow structure. Wastewater flows into the upper storage chamber through the inlet of the anti-backflow structure. The wastewater in the storage chamber is guided to the upper drain hole of the anti-backflow structure, which is connected to a transition chamber. The transition chamber has an air intake channel connecting to the outside. Wastewater flows through the transition chamber into the lower outlet hole, connecting to the drain pipe. This layout not only changes the original flow path of wastewater but also effectively prevents siphoning if the main water purifier suddenly stops working during wastewater treatment, thus maintaining the safety of the water purification system and environmental hygiene. At the same time, this design also improves drainage efficiency and helps reduce the potential risk of water pollution. The application of the anti-backflow structure in the water purifier system significantly improves ease of use and product safety.
