Technical Field

[0001] The utility model relates to the technical field of faucets, and particularly relates to an integrated pull-out faucet. Background Art

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucets is very fast. It has developed from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will consider various aspects such as material, function, and shape when purchasing a faucet. As one of the many types of faucets, a pull-out faucet can pull out the pull-out pipe during use, thereby obtaining a larger water outlet range and playing an extremely important role in places such as kitchens and bathrooms.

[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: the bottom of the shell of the existing pull-out faucet is provided with threads, and during use, it needs to be used in cooperation with a positioning piece provided with a corresponding valve core water inlet channel. After the positioning piece is screwed in, an additional base ring needs to be screwed into the bottom of the faucet shell to fix the positioning piece. There are many separately produced accessories required, and the production cost is relatively high. At the same time, after production, additional installation steps are required, and the installation and use are cumbersome. And using integral casting molding requires consuming more sand cores. The sand cores are disposable items and are discarded after use, which is likely to cause pollution, and at the same time, the processing cost is high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an integrated pull-out faucet with lower cost and simple installation and use in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: an integrated pull-out faucet, including a faucet shell and a valve core installation pipe welded on one side of the faucet shell. A pull-out pipe installation plate is welded on the top surface of the faucet shell. A valve core is arranged inside the faucet shell. The valve core includes a valve core seat welded and installed inside the valve core installation pipe, and a water inlet pipe with one end welded and fixedly connected to the valve core seat and communicating with each other. One end of the valve core seat is also welded and fixedly connected to an outlet pipe and communicating with each other. A base positioning plate is welded at the bottom of the faucet shell. The bottom end of the water inlet pipe penetrates the base positioning plate and is welded to the base positioning plate. The bottom end of the outlet pipe penetrates the base positioning plate and is welded to the base positioning plate.

[0006] Further improvement is: a pull-out water connection pipe is also arranged inside the faucet shell. The top end of the pull-out water connection pipe is communicated with and welded to the pull-out pipe installation plate. The bottom end of the pull-out water connection pipe penetrates the base positioning plate and is welded to the base positioning plate.

[0007] Further improvement: protective materials are filled in the gaps between the faucet housing and the water inlet pipe, and between the faucet housing and the pull-out connecting water pipe.

[0008] Further improvement: the protective material is composed of a mixture of iron sand, stainless steel sand and glue.

[0009] Further improvement: the water inlet pipe includes a cold water inlet pipe and a hot water inlet pipe.

[0010] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: after installing the valve core and the pull-out connecting water pipe in the faucet housing, a base positioning plate is welded at the bottom of the faucet housing, and then the faucet can be completed only by welding the base positioning plate on the faucet base. There are few accessories that need to be produced separately, saving production costs. At the same time, when used after production, the external water pipe can be directly connected through the base positioning plate without additional installation steps of accessories, making it more convenient to use. At the same time, there is no need to use a sand core for production, which saves more costs and makes the production process more environmentally friendly. Description of the Drawings
