[0002] A Chinese patent document with publication number CN101392850A discloses a faucet, which includes a faucet main body, which is equipped with a bottom cover, an outer shell, a valve seat, an outlet pipe and an inlet pipe. The faucet main body includes a first combined individual and a second combined individual obtained by cutting the complete faucet from top to bottom. The first combined individual includes the valve seat and the upper part of the outlet pipe, and the second combined individual includes the lower part of the outlet pipe, the inlet pipe and the bottom cover. The first combined individual and the second combined individual can be combined along the cut to obtain a complete faucet main body.

[0003] In the above solution, after the faucet is fixedly installed, the water outlet direction of the water outlet pipe is fixed and cannot be adjusted, making it inconvenient for users to adjust the water outlet direction of the water outlet pipe according to their needs, and the valve seat is likely to become loose during long-term use. Utility Model Content

[0004] The utility model aims to provide a faucet which can prevent the valve body from loosening and shortening the service life.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A faucet includes a shell, a water outlet pipe and a valve body, wherein the valve body is arranged in the shell, and the water inlet end of the water outlet pipe is rotatably arranged at the upper end of the valve body. The faucet is characterized in that a limiting member is further provided between the lower end of the valve body and the shell so that the water outlet pipe will not drive the valve body to rotate when it rotates.

[0007] Through the above solution, during use, the water outlet pipe can be rotated according to different needs so that the water outlet effect of the water outlet pipe meets the needs, and when the water outlet pipe is rotated, the valve body will not affect the fixed position of the valve body under the action of the limit member, thereby ensuring the stability and consistency of water flow control, reducing the wear of the valve body due to frequent rotation, and extending the service life of the faucet.

[0008] A first mounting hole is formed at the lower end of the shell, and the valve body is installed in the shell through the first mounting hole. The limiting member is a plate-shaped structure adapted to the first mounting hole, and the limiting member has a first limiting portion protruding outward, and the first mounting hole is formed with a first limiting recess that cooperates with the first limiting portion. The limiting member is formed with a positioning hole for the lower end of the valve body to pass through, and a second limiting portion protruding outward is formed on the outer peripheral surface of the valve body, and the positioning hole is formed with a second limiting recess that cooperates with the first limiting portion.

[0009] Through the above scheme, the plate-like structure design of the first mounting hole and the limiting part makes the installation of the valve body easier. During installation, it is only necessary to install the valve body from the first mounting hole, align the first limiting part with the first limiting recess, and pass the lower end of the valve body through the positioning hole, and then use the second limiting recess of the positioning hole and the second limiting part to cooperate to fix the valve body in the shell.

[0010] The positioning hole is formed with a wire passing portion through which the power supply wire passes.

[0011] Through the above solution, the lines can be connected conveniently.

[0012] The valve body is formed with a limiting step which abuts against the top of the limiting member.

[0013] The above solution can prevent the limiter from separating from the valve body after installation, making the valve more stable after installation.

[0014] It also includes a locking piece, the first mounting hole is formed with an internal thread, the outer peripheral surface of the locking piece is formed with an external thread that matches the internal thread, and the locking piece is formed with an avoidance hole for the lower end of the valve body to pass through.

[0015] Through the above solution, the locking piece can prevent loosening due to vibration or rotation during use by cooperating with the internal thread of the mounting hole. The design of the avoidance hole allows the lower end of the valve body to pass freely, which can facilitate its avoidance of the valve body for installation.

[0016] A second mounting hole is formed at the upper end of the shell, a socket opening upward is formed at the upper end of the valve body, and the water inlet end of the water outlet pipe passes through the second mounting hole and is rotatably connected to the socket opening.

[0017] The above solution can facilitate the assembly of the water outlet pipe. During assembly, it is only necessary to pass the water inlet end of the water outlet pipe through the second installation hole and align it and install it into the socket to complete the installation of the water outlet pipe.

[0018] A sealing ring is also provided between the receiving port and the water inlet end.

[0019] Through the above solution, the provision of a sealing ring can effectively provide sealing and prevent water leakage.

[0020] A sealing member is also provided between the water inlet end and the second mounting hole. A limiting groove adapted to the sealing member is formed on the outer peripheral surface of the water inlet end so that the sealing member can be sleeved in the limiting groove. The sealing member is located above the receiving interface and between the water inlet end and the second mounting hole.

[0021] Through the above solution, the seal can further prevent the occurrence of water leakage. The design of the limit groove enables the seal to be firmly fixed in the appropriate position, which is convenient for users to quickly align and install during the installation process and reduces the difficulty of operation.

[0022] It also includes a sensing device, which includes a main body and a sensing head. The main body is fixedly arranged in the shell, and a through hole adapted to the sensing head is formed on the side of the shell, so that the sensing head can pass through the through hole after the sensing device is installed.

[0023] Through the above solution, the sensor head can detect the user's hand or object and automatically control the water output, which can effectively reduce water waste and avoid long-term water flow, especially when washing hands or cleaning items, helping to save water. The main body is fixed in the shell, and the perforated design makes it easy to position and install the sensor head.

[0024] The shell and the valve body are both made of ceramic.

[0025] Through the above solution, the ceramic material has good corrosion resistance, can effectively resist the erosion of various chemical components in water, and extend the service life of the faucet. BRIEF DESCRIPTION OF THE DRAWINGS
