Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water faucet, especially to a multifunctional concealed basin faucet double-sleeve protection structure. BACKGROUND

[0002] The concealed basin faucet is buried in the wall, and only the operating handle and the water outlet are exposed on the surface of the wall. Compared with the traditional faucet installation method, the concealed basin faucet has an attractive appearance and does not occupy the basin space, facilitating basin cleaning and being favored by consumers.

[0003] After searching, the Chinese utility model patent with patent application number CN202322564228.0 discloses a super-thin water outlet concealed basin faucet structure, relating to the technical field of bathroom products, which comprises a pre-buried box, a body, a fixed joint, a communication joint, a first top screw, a water outlet, a first screw, a bubbler, a handle, a second top screw, a sheath, a gland, a flat foot valve core, a sleeve, and a second screw, etc. The utility model adopts a middle water connection joint, two side connecting studs, a threaded hole under the water outlet, and a top screw structure to lock the water outlet. After installation, the water outlet cannot rotate 360 degrees. The valve core is directly installed on the main body, which adopts an integrated structure. The sleeve is only used as an appearance part screwed on the outside of the main body to ensure that the position of the sheath relative to the main body is correct. The concealed box is also provided with a level meter to adjust the level during the installation of the concealed pre-buried box, which facilitates the installation of the concealed pre-buried box and ensures the horizontal alignment and perpendicularity to the wall surface during the installation of the water outlet and handle.

[0004] For example, the patent application number CN202022500532.5 discloses a concealed basin faucet with multi-directional rotation, which comprises a faceplate, a water inlet switch and a water outlet pipe are arranged on the faceplate, the water outlet pipe comprises a first pipe body, a second pipe body is movably connected to the top of the first pipe body through a bearing, a side pipe extends from the side of the second pipe body, the top of the side pipe is movably connected to the side of a third pipe body through a bearing, a fourth pipe body is movably connected to the top of the third pipe body through a bearing, upper and lower water outlets are arranged on the fourth pipe body, and control switches are arranged on the fourth pipe body to control the water outlets. The water outlet pipe used in this product is movably connected by multiple pipe bodies through bearings, which can realize multi-degree-of-freedom rotation, increase the working range, and improve the practicality of the faucet.

[0005] Although the existing concealed basin faucet can meet the basic use requirement, the sleeve and other wall external parts are installed in advance during the early stage of pre-embedding installation, and the wall external parts can be damaged during the later stage of decoration construction; and when the user needs to disassemble and replace the outer sleeve or other wall external parts during the later stage of use, the pre-embedded box and the faucet body are disassembled together, and the wall body needs to be broken to complete the disassembly and installation, which is time-consuming and laborious, and the later stage maintenance cost is high.
