Part 621 engages with the first slot 2311 and abuts against the first annular stepped surface 11, fixing the inlet connector 1 and connector seat 2 relative to each other along the second direction. Thus, the outlet component 4 can rotate relative to the connector seat 2 around its rotation axis with the connecting pipe 5, and can also rotate relative to the inlet connector 1 with the connector seat 2 along with the connecting pipe 5, achieving multi-directional and multi-angle adjustment of the water outlet. Compared to existing technologies, the first engaging part 6, through the engagement of the second engaging part 621 and the first slot 2311, fixes the connector seat 2 and the inlet connector 1 relative to each other along the second direction, and through the engagement of the first engaging part 61 and the first annular groove 511, fixes the connecting pipe 5 and the connector seat 2 relative to each other along the first direction, preventing the connecting pipe 5 from becoming detached from the inlet component during rotation. This simplifies the structure and makes assembly more convenient.

[0040] In this embodiment, a filter element 3 is installed at the water inlet connector 1 to filter impurities in the water; the water outlet assembly 4 includes a water outlet connector 41 and a water outlet element 42, making the configuration of the water outlet element 42 more flexible and allowing for flexible selection according to user needs.

[0041] In this embodiment, the first annular groove 511 is provided with an arc-shaped surface to facilitate the quick positioning of the first snap-fit ​​part 61, so that the connection between the first snap-fit ​​part 6 and the connecting pipe 5 is quick.

[0042] In this embodiment, a first guide slope 2321 is provided to facilitate the quick assembly of the first snap-fit ​​component 6 and the connector seat 2.

[0043] In this embodiment, the first snap-fit ​​component 6 engages with the first annular stepped surface 11 and the second snap-fit ​​part 621 engages with the first snap-fit ​​groove 2311, thereby fixing the water inlet connector 1 and the connector seat 2 in the second direction. The structure is simple and easy to assemble.

[0044] In this embodiment, the second snap-fit ​​part 621 engages with the inclined surface of the connector seat 2 via the second guide inclined surface 6211, and undergoes radial elastic deformation to enter the first snap-fit ​​groove 2311, thereby engaging with the first snap-fit ​​groove 2311. The inclined surface engagement makes assembly easier, and due to the force of elastic deformation, the second snap-fit ​​part 621 has the effect of tightly fastening the groove wall of the first snap-fit ​​groove 2311, making the connection between the water inlet connector 1 and the connector seat 2 more secure.

[0045] In this embodiment, the first protrusion 6131 is adapted to extend into the first annular groove 511 to abut against the bottom of the first annular groove 511, and the first abutting surface 6132 abuts against the end face of the first annular groove 511, thereby increasing the frictional force between the first snap-fit ​​part 61 and the first annular groove 511 in the axial direction of the first connecting end 51, making the connection between the connecting pipe 5 and the connector seat 2 more secure.

[0046] In this embodiment, the water outlet connector 41 is sealed and inserted into the second connecting end 52, so that it can rotate relative to the connecting pipe 5; and the third snap-fit ​​part 71 and the second annular groove 521 are engaged and fixed relative to the connecting pipe 5 along the insertion direction, so as to prevent the water outlet assembly 4 from loosening when rotating.

[0047] In this embodiment, the second snap-fit ​​member 7 is fixedly connected to the water outlet connector 41 by abutting against the second annular stepped surface 4123 and by the fourth snap-fit ​​part 72 being snapped into the second slot 4122. The structure is simple and easy to assemble.

[0048] In this embodiment, the second protrusion is adapted to extend into the second annular groove 521 to abut against the bottom of the second annular groove 521, and the second abutting surface abuts against the end face of the second annular groove 521, thereby increasing the frictional force between the third snap-fit ​​part 71 and the second annular groove 521 in the axial direction of the second connecting end 52, making the connection between the water outlet connector 41 and the connecting pipe 5 more secure.

[0049] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
