Small, so that the overall structure can achieve water and voltage regulation; in addition, when entering the water, the control group. (30) can be linearly displaced on the throttling group (21) to block the pressurized The water flows countercurrently to achieve the effect of regulating water pressure and preventing backflow. In addition, the air hole (14) of the present invention is designed such that air in the water discharge portion (41) can pass through the second air chamber (31), and enter the first gas via the gap of the through hole (261) groove (261). The chamber (25) is derived from the air hole (14) and has the function of regulating the air pressure, thereby effectively avoiding the phenomenon that the pressurized water flows in the water outlet portion (41) to produce and disturb the flow, and has excellent innovation and practicability. M397461 This water-saving joint structure with pressurization and anti-backflow can be used to connect the main body (1G) to the water flow, and the other end can be connected to, for example, a faucet, a gardening faucet, a shower head, etc. On all kinds of water discharge devices (40), the assembly is very convenient, so as to achieve excellent convenience and practicality. In summary, the "water-saving joint structure" disclosed in the present invention is a structure of a flow-rate device (10) which is disposed inside the body (10) and has a throttle group (2) and is disposed therein. The throttle group (21) can be used as a line-displacement-control group (3〇), and a hole (14) is formed in a side edge of the body (1〇), so that the water flow (141) passes through the throttle group. (21) When flowing to the water inlet portion (41) of the water discharge device (4〇), the elastic displacement action of the regulation group can resist the reverse flow of the pressurized water flow, and the air in the water inlet portion (4) can be ventilated by the air hole ((4) Derivation' has the dual functions of regulating water pressure and air pressure, and can achieve the voltage regulation effect, and the water supply and water supply capacity of the province is high, and the overall structure is practical and innovative. Benefits, and its composition and structure have not been seen in the publications or public use, and it is in line with the new patent application. • The requirements are 'please request!
