New description: [New technical field] The present invention relates to a drinking water device, in particular to a faucet with an air gap waste pipe suitable for water purification equipment. [Prior Art] A faucet (tw M375799 patent) applied to a water purifier as shown in FIGS. 1 and 2 includes a housing 1, an inlet pipe 2 fixed to the bottom of the housing i. a gooseneck 3 fixed to the top of the casing and a switch 4 for controlling the water discharge state of the gooseneck 3 and a drainage return pipe 5 installed inside the casing i and having an inverted U shape, the drainage back The tube 5 has a waste water inlet section 501' - a waste water outlet section 502 and a reverse stop air hole 5 〇 3 provided at the top, and the reverse rustic hole 503 can generate a gas barrier phenomenon to block the waste water inlet of the drain return pipe 5 The section 501 and the waste water outlet section 5〇2 can prevent the foreign matter in the waste water from flowing back to the inside of the water purification equipment to achieve the safety and hygiene of the drinking water. Although the faucet utilizes the setting of the backstop vent 503 of the drain return pipe 5 to achieve the intended use purpose, since the drain return pipe 5 still extends continuously, even if the backstop vent 503 is utilized, a gas resistance phenomenon may occur. In order to block the waste water inlet section 501 of the drain return pipe 5 and the waste water discharge section 5〇2, the bacteria attached to the pipe wall of the drain return pipe 5 may still flow back along the waste water inlet section 105. The inside of the water purification equipment 6. Further, the diameter of the drain return pipe 5 is small, and the diameter of the reverse stop air hole 5〇3 is also small. Then, after a period of continuous use, the reverse stop air hole 503 may be blocked by foreign matter and lose its air resistance. [New content] M424419 Therefore, the purpose of the present invention is to provide a faucet having an air gap waste pipe which can surely generate a gas barrier and can achieve drinking water hygiene. Therefore, the faucet having the air gap waste pipe includes a valve body and a gas resistance unit. The valve body has an inlet pipe, an outlet pipe, and a pipe between the inlet pipe and the outlet pipe and can control the outlet. a control member for the water outlet state of the water pipe, the gas resistance unit having a base mounted on the valve body and a drainage return pipe of the wearer on the base, the base having an introduction officer capable of introducing waste water and a dischargeable waste water a drain pipe having a first pipe section connected to the inlet pipe and an elbow pipe section connected to the top of the first pipe section, the pipe section having a port corresponding to the discharge pipe and The discharge tube is spaced apart to form an air gap. The utility model has the advantages that the port of the elbow section corresponds to the discharge pipe and forms an air gap with the discharge pipe, thereby effectively generating a gas barrier effect and avoiding the return of bacteria or foreign matter in the waste water, and reaching Drinking water is hygienic. [Embodiment] The foregoing and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in Fig. 3, Fig. 4 and Fig. 5, a preferred embodiment of the faucet having an air gap waste pipe comprises a valve body 1〇 and a gas resistance unit 2〇. The cymbal body 1 has an upper housing n, a lower housing 12 mounted below the upper housing u, an inlet pipe i3 mounted at the bottom of the lower housing 12, and a top mounted on the upper housing U The outlet pipe 14 and the control member 15 installed in the middle of the upper casing 4 seat 11 are between the inlet pipe 13 and the outlet water & 14 and can control the outlet state of the outlet pipe i 4 . The lower housing 12 has a ring wall m surrounding the forming inner hole 121 and an opening disposed in the outer cover 122 and connectable to the inner hole 121. The ring wall m has a bottom surface and The groove portion 124 is formed in a groove shape, and the inner hole 121 has a class shape of a narrow upper and lower width. The air resistance unit 20 has a base 21 mounted to the lower housing 12 of the valve body 10 and a drain return pipe 22 mounted to the base 21. The base 21 has a bottom wall 211, a peripheral wall 212 extending upward from the periphery of the bottom wall 211, and an introduction tube connected to the bottom of the bottom wall 211 and capable of introducing waste water discharged from a water purification device (for example, reverse osmosis). 213 and a discharge 214 capable of discharging waste water, the bottom wall 211 and the peripheral wall 212 together define an opening 215 facing upward, the bottom wall 211 is disposed at the open end of the inner hole 121, and has a The positioning portion 216 is formed in a convex shape, and the locking portion 124 of the ring wall 122 and the positioning portion 216 are complementary to each other and can be nested with each other. The bowing tube 213 is disposed adjacent to the discharge tube 214, and the discharge tube 214 has a drain hole 214 corresponding to the bottom wall 211 and connectable to the chamber 215. In addition, the bottom wall 211 is further provided with a support frame 217. The drain return pipe 22 has a first pipe section 221 connected to the inlet pipe 213 and an elbow section 222 connected to the top of the first pipe section 221. The first pipe section 221 is fixed to the bottom wall 211 of the base n. The elbow section 222 spans the top of the sub-frame 217 and has a port 223 corresponding to the discharge tube 214 and spaced apart from the discharge tube 214 to form an air gap. The area of the chamber 215 is larger than the area of the port 223, and the port 223 is disposed opposite to the drain hole 214'. The area of the drain hole 214' is larger than the area of the port 223, and the opening of the lower shell 12 is 123 corresponds to the port 223 of the drain return pipe 22, and as shown in FIG. 4 and FIG. 5, when the faucet assembly is completed and the installation is positioned on a table 100, the oxygen resistance unit 20 can be firmly fixed to the lower case. In the inner hole 121 of the seat 12, the introduction tube 213 can be connected to the waste water discharged from the water purification device (not shown in the same manner as in Fig. 1), and the discharge pipe 214 can be connected to the discharge pipe of a water tank (Fig. Not shown, similar to Figure 1). And when the water purification equipment is performing the water purification manufacturing operation, the waste water generated by the water purification equipment can be introduced into the drainage return pipe 22' by the introduction pipe 213 and dripped down from the port 223 of the curved pipe section 222 to the chamber. After 215, the drainage pipe 214 is further guided to the discharge pipe 214 and the discharge pipe of the water tank. When the water purification device stops the water production, the waste water in the introduction pipe 213 and the drainage return pipe 22 is stationary, but due to the air gap formed by the port 223 and the discharge pipe 214, and the generated gas resistance, The waste water accumulated in the chamber 215 and the waste water in the discharge pipe 214 can be completely discharged into the discharge pipe of the water tank, and the waste water level in the drainage return pipe 22 can be effectively reduced, and the wastewater backflow can be blocked, and It can effectively prevent bacteria or foreign matter from returning to the inside of the water purification equipment to achieve the sanitation of drinking water. Moreover, the user can also observe the wastewater discharge condition of the drainage return pipe 22 through the opening 123, and can use a tool to extend from the opening 123 and clean the port 223 for a period of time, thereby preventing the port 223 from being cleaned. This port 223 is blocked by foreign matter and ensures that the air resistance function is normal. However, the above is only a preferred embodiment of the present invention, and does not limit the scope of the present invention to M424419, that is, the simple equivalent change of the patent scope and the new description of the novel towel. And the modifications are still within the scope of this new patent. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing the installation of a faucet applied to a water purifier.
