Description

Technical Field

[0001] The invention relates to an induction faucet in a sanitary ware, in particular to a screw-in quick-installation hidden induction faucet. Background Art

[0002] As living standards improve, people have increasingly higher expectations for the appearance and functionality of faucets. As intelligent sanitary ware, sensor faucets have become a popular choice among consumers. To save installation space and enhance aesthetics, wall-mounted sensor faucets typically adopt a concealed installation structure, where the faucet's water inlet pipe and other components are installed within the wall. Most existing concealed sensor faucets are directly fixed to a pre-embedded box or mounting base embedded in the wall using connectors such as screws or bolts. Specifically, the connector is directly fixed to the rear of the faucet. For extended faucets, the entire faucet is connected by only one or two axial screws at the rear. The water outlet on the exterior of the wall is relatively long. If external forces act on the top of the outlet during use, the faucet and its connector can easily become detached from the embedded box or twisted, compromising safety and shortening its service life. If the faucet malfunctions or needs to be replaced with this installation method, the entire faucet must be removed using tools, which is complex and requires a high level of expertise, causing significant inconvenience and confusion for users. Summary of the Invention

[0006] The fixing seat includes a fixing plate and a fixing sleeve. The fixing plate is inserted into the installation chuck, and the fixing sleeve is inserted into the free end of the embedded box. The fixing plate is provided with a positioning notch and a sliding piece.

[0007] The fixing plate and the mounting chuck are connected by radial limitation between the limiting block and the slide, and circumferential limitation between the limiting block and the positioning notch, so that the mounting base and the fixing seat are rotatably connected.

[0008] As a preferred technical solution: the positioning sleeve of the mounting base and the fixing sleeve of the fixing seat are concentrically mounted.

[0015] As a preferred technical solution: mounting holes are respectively provided on the positioning chuck and the fixing plate.

[0016] Compared with the existing technology, the present invention adopts a rotating clip method to achieve the connection and fixation of the faucet and the embedded box. It has a simple structure and is easy to install and operate. It can significantly increase the axial and vertical bearing capacity of the water outlet end of the sensor faucet, effectively preventing the faucet from detaching or offsetting.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See attached Figure 1-9 The induction faucet disclosed in the present invention is a screw-in quick-installation hidden induction faucet that adopts a rotating buckle to achieve the connection and fixation between the faucet and the embedded box.

[0029] This screw-in quick-installation hidden sensor faucet includes an embedded box 2 connected to the wall, a water outlet 4 with a bubbler assembly 7 installed at the free end, and an inlet pipe assembly 5 running through the inside of the water outlet 4. The fixed end of the water outlet is connected to the embedded box via a connection assembly such as a high-strength bolt, and the water inlet pipe assembly inside is connected to a hose assembly 9 running through the central part of the embedded box; it also includes a mounting base 3 arranged at the fixed end of the water outlet, and a fixing seat 8 arranged at the free end of the embedded box (i.e., outside the cavity).

[0030] The mounting base includes a mounting joint 3-1, a mounting chuck 3-2, a first limiting block 3-3, a positioning joint 3-4, and a second limiting block 3-5. The center of the mounting base is a mounting chuck 3-2 with a disc structure. The central parts of the two sides of the disc are respectively protruding mounting joints 3-1 and positioning joints 3-4 with hollow cylindrical structures. The mounting joint is connected to the water outlet, and the positioning joint is inserted into the fixed seat. The inner wall of the positioning joint is connected to the hose assembly arranged inside it. A limiting block is provided on the mounting chuck. 4. The side of the mounting chuck is a groove structure. Two radially symmetrical limiting blocks are provided on the upper and lower sides of the inner side of the groove, namely the first limiting block 3-3 and the second limiting block 3-5. A groove, namely a slide, is formed between the first limiting block and the mounting chuck. The slide at the upper end of the fixed disc is inserted into the groove-shaped slide, forming a sliding fit with the first limiting block; the end face of the first positioning notch contacts the side face of the first limiting block. A positioning bolt hole is provided under the second limiting block below; the side surface of the second limiting block contacts the end surface of the second positioning notch on the fixed plate. The fixed plate rotates in a circle within the groove wall of the positioning clamping plate to achieve limiting clamping and loosening.

[0031] The fixed base includes a fixed disc 8-1, a fixed sleeve 8-2, a slide 8-3, a first positioning notch 8-4, and a second positioning notch 8-5. The fixed disc is inserted into the mounting chuck and embedded in the groove structure on the side of the mounting chuck. The central through-hole of the fixed sleeve is inserted into the free end of the embedded box. The fixed disc is provided with a positioning notch and a slide 8-3; the positioning notches are the first positioning notch 8-4 and the second positioning notch 8-5. The fixed disc and the mounting chuck are radially limited between the limit block and the slide, and circumferentially limited between the limit block and the positioning notch, achieving a rotational connection between the mounting base and the fixed base.

[0032] The positioning sleeve of the installation base and the fixing sleeve of the fixing seat are concentrically mounted. Figure 2 As shown, the inner wall of the positioning joint is threaded, connecting to the threads on the outer wall of the positioning sleeve 9-2. The inner wall of the positioning sleeve is connected to the threaded joint 9-1 at the end of the hose assembly; the other end of the positioning sleeve is connected to the end of the water inlet pipe assembly, which is inserted into the mounting joint. The entire hose assembly is connected to the water inlet pipe assembly via the positioning sleeve and threaded joint, which extend through the through-holes in the center of the mounting base and the fixing base. The fixing base is pre-installed on the free end of the embedded box using mounting holes and bolts. The mounting base is fixed to the tail end of the water outlet. The water outlet is fixed to the embedded box by a rotating clip between the mounting chuck and the fixing plate, making installation simple and quick.

[0033] The mounting joints and positioning joints on both sides of the mounting chuck are composed of two arc-shaped structures combined together to form a cylindrical structure with a gap in the middle, which is convenient for installation and selection.

[0034] The positioning chuck and the fixing plate are respectively provided with mounting holes.

[0035] The disk body at the second positioning notch of the fixed disk is a sloped structure, which contacts the bolt in the positioning bolt hole on the second limit block to achieve a double connection between the fixed seat and the mounting base. In addition to the axial connecting piece connection between the two, the joint of the two also adopts a circumferential selection buckle, which improves the installation convenience while also improving the assembly and cotton neps, thereby improving stability.
