Description

Technical Field

[0001] The utility model belongs to the technical field of pull-out kitchen faucets, and particularly relates to a pull-out kitchen faucet and a valve core. Background Art

[0002] With the development of society, there are various styles of current kitchen faucets. In order to spray water without dead angles, pull-out faucets have emerged as the times require. The existing pull-out faucets mainly include a core pipe and a pull-out pipe. The core pipe is fixedly connected to the water outlet base. One end of the pull-out pipe is sleeved on the core pipe and can move relatively, and the other end is connected to the water outlet head. A weight is arranged at the end of the pull-out pipe sleeved on the core pipe. When pulling out and spraying water, the user resists the gravity of the weight to pull out the pull-out pipe. When the pull-out pipe moves, it drives the weight to slide on the surface of the plastic water pipe. After completion, let go, and the pull-out pipe returns to its original position under the gravity of the weight. However, the fall of the weight entirely depends on gravity. When the weight falls and slides on the surface of the plastic water pipe, the friction between the weight and the plastic water pipe is relatively large.

[0003] And the long-term friction will cause wear on the surface of the plastic water pipe. As the weight repeatedly falls and slides, the friction force will gradually wear off the material on the surface of the water pipe, thereby easily reducing the structural strength of the water pipe.
