Description

Technical Field

[0001] This application relates to the field of valve core technology, and in particular to a valve core with a filtering function. Background Technology

[0002] The valve core is a valve component that enables basic functions such as directional control, pressure control, or flow control through the movement of the valve body. The valve core is installed inside the faucet. The valve core includes a housing and a base. The side wall at the bottom of the base has a cold water inlet, a hot water inlet, and a water outlet. The temperature of the water flowing out of the water outlet changes due to the adjustment of the internal structure of the housing. However, the current water resources are seriously polluted, resulting in poor water quality flowing into the cold water inlet and the hot water inlet. Subsequently, an external water purification device is connected to improve the water quality. However, connecting an external water purification device will increase the installation cost of the water supply device and increase the work efficiency of installing the faucet.
