Description

Technical Field

[0001] This utility model relates to a shower faucet. Background Technology

[0002] The existing technology, Chinese patent CN202220023064.3, describes a low-cost shower faucet with a storage compartment. It includes a faucet mounting box with an open top, a storage plate on the top cover of the mounting box, and two mounting bodies for a diverter valve core and a mixing valve core respectively installed inside the mounting box. A diverter valve core and a mixing valve core are installed on the front side of the diverter valve core mounting body, and a cold water inlet and a hot water inlet are installed on the rear side of the mounting box. A cold water inlet connecting pipe and a hot water inlet connecting pipe are respectively provided on the rear side of the mixing valve core mounting body, communicating with the cold water inlet and the hot water inlet. A mixing connecting pipe connects the diverter valve core mounting body and the mixing valve core mounting body. The problem is that there is a risk of the diverter valve core becoming loose.

[0003] Chinese patent CN202110303482.8 discloses a valve core structure, including a valve core housing, a rocker arm, a rotating shaft, a paddle, a rotating component, a fixed component, and a front valve core piece. The rocker arm is connected to the rotating shaft, which is connected to the upper end of the valve core housing. The front valve core piece is connected to the lower end of the valve core housing, and the inner side of the front valve core piece is connected to the front of the fixed component. The rotating component is attached to the back of the fixed component and connected to the paddle. The paddle, driven by the rocker arm, causes the rotating component to slide up, down, left, and right within the range of the back of the fixed component. Problems include: the outlet end is flat, and the inlet and outlet holes align with the water holes of the valve core seat, posing a potential leakage risk; rotation is prevented by an end positioning post.
