[0002] In the existing market, as long as there is a kitchen faucet with water purification, the faucet is set on the countertop, while the water purification main unit is set under the countertop. Therefore, the function of discharging waste water from the water purification main unit is directly connected to the sewer for direct discharge. However, when the water purification main unit starts and stops working, it is easy to have a siphon effect, resulting in the waste water being easily refluxed through the waste water pipe. These waste waters are easily refluxed into the filter, contaminating the filter element of the filter, causing the problem that the purified water may not meet the standard in the later stage. At the same time, there is no technology of multifunctional faucets in the existing technology. They are all separate products. The water purification equipment corresponds to the water purification faucet, and the kitchen water corresponds to the kitchen faucet. Moreover, the overall space is limited. There is only a swing arm rotation, and the water outlet pipe cannot be pulled out.

[0027] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless specifically defined otherwise.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms such as "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.

[0030] Referring to the accompanying drawings of the specification, a kitchen water purification faucet includes a faucet. An inner body 10 capable of circulating wastewater is provided inside the faucet. A wastewater pipe 11 of a water purification main unit is connected to the lower end of the inner body. The water purification main unit is not drawn in the figure. A water storage cavity 12 is provided above the inner body. The wastewater in the wastewater pipe can flow from bottom to top into the water storage cavity. An upper drain hole 13 is provided at the lower end of the water storage cavity. A transition cavity 14 is provided in the inner body below the upper drain hole. An outlet hole 15 is provided at the lower end of the transition cavity. A drain pipe 16 is connected to the outlet hole. An air intake channel 17 is also provided on the inner body. The air intake channel can communicate the atmosphere with the transition cavity. The air outlet of the air intake channel is located at the upper end of the transition cavity, which can prevent wastewater from flowing out of the air intake channel and causing water leakage when there is too much water flow. During use, the water purification main unit is usually installed under the countertop, and the faucet is installed on the countertop. The wastewater of the present invention is not directly connected to the sewage pipe (the sewage pipe can also be connected to the drainage of a household sink), but first flows upward into the anti-backflow structure on the countertop. The water flowing out through the upper drain hole forms a negative pressure in the transition cavity, connecting the transition cavity with the atmosphere and sucking in air, so that the overall water flow can be saturated in the pipe, improving the drainage efficiency. The aperture of the upper drain hole can become smaller in the water flow direction, and the aperture of the outlet hole is larger than the space of the upper drain hole. In this way, even when the water purification main unit is turned off and there is a sudden pressure change, it is easy to generate siphonage. However, the air intake channel can prevent the backflow of wastewater and prevent it from flowing back into the filter element and causing pollution.

[0031] Preferably, the faucet includes a base 20 that can be installed on the countertop. A bent pipe 30 is provided above the base. The inner body is installed inside the base, so that the anti-backflow structure can be integrated with the faucet. A pull-out pipe 40 and a purified water outlet pipe 50 are provided inside the bent pipe. A pull-out head 61 is provided at the water outlet end of the bent pipe. The pull-out head is detachably connected to the bent pipe, that is, the pull-out head can be pulled out for use. A purified water outlet nozzle 62 is also provided at the water outlet end of the bent pipe. The water outlet end of the purified water outlet pipe can communicate with the purified water outlet nozzle. The purified water outlet nozzle is fixedly installed at the water outlet end of the bent pipe, that is, the purified water outlet end is relatively fixed.

[0032] Further, a water channel body 21 is also arranged inside the base. The inner body can be adapted to the water channel body. It further 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 the purified water outlet pipe to control the outlet of purified water. The outlet end of the mixing valve can be cooperatively connected with the pull-out pipe. The inlet end of the mixing valve can be communicated with the cold water pipe and the hot water pipe to control the outlet of domestic water and the adjustment of the water temperature. A first handle 24 and a second handle 25 are also arranged on the base. The first handle 24 can be cooperatively connected with the switch valve, and the second handle 25 can be cooperatively connected with the mixing valve. These two handles are distributed on both sides of the base. The purified water inlet pipe 51, the purified water outlet pipe 50, the cold water pipe 71, the hot water pipe 72, and the pull-out pipe can be inserted and cooperated with the water channel body. That is to say, corresponding flow channels are arranged inside the water channel body. The flow channels connect the inlet pipe and the valve core, and then can also connect the outlet end of the valve core with the pull-out pipe and the purified water outlet pipe.

[0033] Furthermore, an outlet body 60 is also arranged on the inner periphery of the outlet end of the elbow pipe. The purified water outlet nozzle is arranged on the outlet body. The pull-out pipe can be cooperatively connected with the pull-out head. A pull rod 63 is arranged on the pull-out head. This pull rod can pull the pull-out head out from the elbow pipe. The pull-out head can be inserted into the slot 64 of the outlet body. One end of this pull rod can extend out to the outside of the elbow pipe for people to operate. The pull-out pipe includes an inner pipe 41 and an outer pipe 42. A spring 43 is arranged between the inner pipe and the outer pipe. The spring is sleeved on the outer periphery of the inner pipe. This can ensure a certain stiffness of the pull-out pipe, making it not soft, and at the same time can prevent the pull-out pipe from being bent. The inlet end of the inner pipe can be inserted and cooperated with the water channel body.

[0034] Compared with ordinary kitchen faucets, the design of this faucet is more advanced. It ingeniously integrates the kitchen faucet, the purified water faucet, and the anti-backflow device into one, changing the design of the existing sewage discharge. This not only simplifies the installation process but also saves space, making the kitchen cleaner and more beautiful. In addition, this faucet is also equipped with a hidden pull-out pipe. When in use, users can easily pull it out for more flexible operation; when not in use, just give it a gentle pull, and it can be retracted and hidden to keep the kitchen tidy and simple. This design not only improves the convenience of use but also adds a sense of modernity and fashion to the kitchen.

[0035] An anti-backflow structure is installed at the faucet. The wastewater pipe for discharging wastewater from the water purification host system is connected to the water inlet end of the anti-backflow structure. Wastewater flows into the upper water storage cavity through the water inlet end of the anti-backflow structure. The wastewater in the water storage cavity is guided to the upper drain hole of the anti-backflow structure. The upper drain hole is connected and communicated with the transition cavity. The transition cavity has an air inlet channel communicating with the outside. The wastewater flows through the transition cavity and into the lower water outlet hole, and is connected to the drain pipe. This layout not only changes the original flow path of the wastewater, but also ensures that in the process of wastewater treatment, when the water purification main body suddenly stops working, the possible siphon phenomenon is effectively prevented, thus maintaining the safety and environmental hygiene of the water purification system. At the same time, this design also improves the drainage efficiency and helps to reduce the potential water pollution risk. The application of the anti-backflow structure in the water purifier system significantly improves the use convenience and the safety of the product.
