Description

Technical Field

[0001] The utility model relates to the technical field of faucet devices, and more specifically, to an inner valve core body and a faucet. Background Art

[0002] A rotary faucet generally includes an outer housing, an inner valve core body disposed inside the outer housing and having an inlet and outlet water flow passage and a valve core mounting seat, a valve core, an inlet water pipe and an outlet elbow. The mounting seat for mounting the valve core on the inner valve core body is usually disposed on the side. During installation, the inner valve core body is usually first installed inside the outer housing, and then the valve core is installed from the side. The valve core and the mounting seat are sealed through the end face. Therefore, when installing the valve core, the valve core will exert a lateral pressure on the mounting seat. However, the water inlet section of the existing inner valve core body is usually composed of two cylindrical water inlet pipes, and the mounting seat is disposed on the water inlet section. When installing the valve core, there is a possibility that the water inlet pipe is not strong enough and is bent or even damaged. Summary of the Utility Model
