Description

Technical Field

[0001] The invention relates to the field of sanitary ware, in particular to a valve core seat fixing structure of a pull-out faucet and the pull-out faucet. Background Art

[0002] For the convenience of kitchen cleaning, pull-out faucets have been widely used in various types of households in various countries. The pull-out water head on it can be stretched and reset within a certain size range with the hose behind it, providing convenience for consumers.

[0003] Due to the use requirements of the pull-out faucet, it is generally necessary to set a mixing valve core on the side wall branch and set a water pipe on the main body. Therefore, it is often necessary to install a valve core seat at the corner of the main body and the side wall branch to fix the mixing valve core and connect the water line. Since the corner is not easily subjected to force, it is difficult to effectively and forcefully fix the valve core seat on it.

[0004] In the existing practice, in the design of this structure, a snap-fit ​​or snap-fit ​​structure is often set between the valve core seat and the side wall branch to achieve the matching of the valve core seat and the side wall branch. Long-term use of the pulling and pulling out of the water head drives the internal hose to slide, which will continuously generate a pulling force on the valve core seat. However, the simple use of the structural matching between the valve core seat and the side wall branch makes the load-bearing capacity of the valve core seat weak, that is, the strength is weak and it is easy to fall off; in addition, this matching method has high requirements on the matching accuracy between the valve core seat and the side wall branch, and it is necessary to make a refined structural design for the inside of the side wall branch. If there is a slight deviation in the accuracy, it is easy to cause the valve core placed therein to be skewed, resulting in a gap between the valve core and the valve core seat, which is easy to leak. Due to the refined production requirements of the side wall branch, the production conditions are strict and the qualified rate of the product is reduced, so the production cost is high and the output is reduced. Therefore, it is necessary to provide a more reasonable matching structure to solve the above problems. Summary of the invention
