Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to an improved pull-out faucet. Background Technology

[0002] Pull-out faucets, as water appliances with spouts that can be detached from their fixed base and flexibly adjusted in position, offer a key advantage in overcoming the limitations of traditional fixed-spout faucets. They can flexibly cover a wider area according to actual needs such as cleaning and operation, making them widely used in kitchens, bathrooms, and other scenarios where flexible water flow is crucial. These faucets typically feature two water flow modes: normal water and aerated water. Aerated water is achieved by switching the aerator's operating mode, introducing outside air to fully mix with the water. However, current aerators often rely on external mechanical switches for switching water flow modes. This structure not only results in a larger overall spout size and more parts but also increases manufacturing complexity and costs, making it difficult to balance product compactness and economic efficiency. Furthermore, existing aerators usually only offer two water flow modes, which no longer meets the diverse needs of users. Utility Model Content

[0024] Working principle: When using this utility model, the input end of the blind pipe 3 is installed on the pull-out pipe of the faucet. After turning on the faucet, water flows through the pull-out pipe into the blind pipe 3, then into the inlet hole 33, then into the second through hole 113 on the diverter seat 19, then into the annular groove 13, and finally sprays out from the first outlet hole 14 to form shower water. Rotating the outer shell 2 on the blind pipe 3 causes the outer shell 2 to drive the second protrusion 123 via the third protrusion 22, and the second protrusion 123 drives the mounting seat 1. 1. By limiting the protrusion 118 with the elastic locking block 12, the mounting base 11 can drive the diverter 19. The diverter 19 rotates relative to the blind pipe 3, so that the water inlet 33 is aligned with the third through hole 115. Then, the water flows through the third through hole 115 into the isolation base 119, and then through the first through hole 16 into the grid base 121. According to Bernoulli's principle, the external airflow enters the air passage 122 through the gap between the first protruding ribs 18, mixes with the water flow, and is then sprayed out by the grid base 121 to form bubble water; The outer casing 2 is rotated so that the water inlet 33 is aligned with the input end of the second water outlet pipe 117, and the water flows directly out through the second water outlet pipe 117 to form blade water. The outer casing 2 is rotated so that the water inlet 33 is aligned with the input end of the first water outlet pipe 116, and the water flows directly out through the first water outlet pipe 116 to form a water column. The first mounting groove 15 is used to accommodate the isolation seat 119, the second mounting groove 17 is used to accommodate the grid seat 121, and the third mounting groove 110 is used to accommodate the movable pin 111 and the spring 112. The spring 112 provides a reset force for the movable pin 111. The movable pin 111 cooperates with the positioning groove 35 to position the rotation of the diverter seat 19. The connecting block 114 cooperates with the positioning sleeve 120 to realize the positioning of the diverter seat 19 and the isolation seat 119. The elastic claw 31 and the first flange 32 are limited by the limiting hole 21, thereby installing the outer casing 2 on the blind pipe 3. The second flange 34 cooperates with the elastic block 12, thereby installing the mounting seat 11 on the blind pipe 3.
