Description

Technical Field

[0001] This utility model relates to the field of water valve structure, and in particular to a hot and cold water mixing valve. Background Technology

[0002] Traditional mechanical hot and cold water mixing valves regulate the water temperature by mixing hot and cold water and adjusting the ratio, greatly facilitating people's lives. They are widely used in bathing and heating accessories. They are mainly composed of an outer shell and an internal mixing valve core. The mixing valve core installed on the horizontal plane is mostly of an upper and lower structure. When the top lever is stressed, it drives the water droplet tray to rotate or move, changing the hot and cold water mixing ratio. When adjusting, the top needs to bear the force. However, because the various components are arranged vertically, the center of gravity is located near the middle. If the center of gravity is too high, the force on the top will cause greater stress at the bottom connection. After long-term use, the stability will deteriorate, and frequent wear and displacement will also cause poor sealing. Utility Model Content
