Valve core seat fixing structure of extraction type faucet, and extraction type faucet

Abstract

The invention provides a valve core seat fixing structure of an extraction type faucet, and the extraction type faucet. The valve core seat fixing structure consists of a facet main body and a valve core seat body of the extraction type faucet in a cooperation manner; the faucet main body consists of a main body hollow pipe and a valve core assembling pipe, wherein the upper part and the lower part of the main body hollow pipe are opened; the sidewall of the main body hollow pipe is branched outwards to form the valve core assembling pipe; the valve core seat body consists of a valve core seatand a fixing seat which is integrated with the valve core seat; the angle formed by the valve core seat and the fixing seat is the same as the angle formed by the main body hollow pipe and the valvecore assembling pipe; a valve core main body is locked inside the main body hollow pipe by using a screw and a positioning pin; the valve core seat is exactly buckled inside the branch valve core assembling pipe, and thus a relatively-high-intensity assembly effect is realized.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a valve core seat fixing structure of a withdrawable faucet and the withdrawable faucet. Background technique [0002] For the convenience of kitchen cleaning, the pull-out faucet has been widely used in various types of households in various countries. The pull-out faucet on it can be stretched and reset in a certain size range with the hose behind it. Consumers provide convenience of use; [0003] Due to the use requirements of the withdrawable faucet, it is generally necessary to install a mixing valve core on its side wall branch pipe, and to install a water pipe pipeline on its main body. Therefore, it is often necessary to install a valve at the corner of its main body and side wall branch pipe. The core seat is used to fix the water mixing valve core and connect the waterway. Since the corners of the corners are not easy to bear force, it is difficult to achieve effective and...

Problems solved by technology

[0003] Due to the use requirements of the withdrawable faucet, it is generally necessary to install a mixing valve core on its side wall branch pipe, and to install a water pipe pipeline on its main body. Therefore, it is often necessary to install a valve at the corner of its main body and side wall branch pipe. The core seat is used to fix the water mixing valve core and connect the waterway. Since the corner of the corner is not easy to bear force, it is difficult to achieve effective and powerful fixing of the valve core seat on it.

[0004] In the existing practice, in the design of this structure, a buckle or snap-fit ​​structure is often used between the valve core seat and the side wall branch pipe to realize the cooperation between the valve core seat and the side wall branch pipe. Pulling out the water head drives the inner hose to slide, which will continuously generate pulling force on the valve core seat, but the simple use of the structural cooperation 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 Weak and easy to fall off; in addition, this matching method has high requirements for the matching accuracy between the valve core seat and the side wall branch pipe, and requires a refined structural design for the interior of the side wall branch pipe. The valve core is deflected, resulting in a gap between the valve core and the valve core seat, which is prone to water leakage. Due to the refined production requirements of the side wall branch pipes, the production conditions are strict and the qualified rate of the product is reduced, so the production cost is high and Yield reduction
