A button valve core and a faucet

Abstract

The invention discloses a key valve core. The key valve core comprises a valve casing, a static valve plate, a dynamic valve plate and a valve rod, a cavity with the bottom end opened is formed at the bottom of the valve casing, the side surface of the cavity is provided with an opening, and a channel with the open top end and communicated with the cavity is formed at the top of the valve casing in the axial direction of the valve casing; the static valve plate and the dynamic valve plate are coaxially arranged inside the cavity of the valve casing in a sleeved mode and are adhered to each other; the valve rod is sleeved inside the valve casing in a sealing mode, the bottom end of the valve rod is fixedly connected with the dynamic valve plate, and the top of the valve rod matches with the channel of the valve casing; a pressing mechanism of an automatic ball pen type is arranged at the tops of the channel of the valve casing and the valve rod, and after being pressed, the pressing mechanism rotates to drive the valve rod to drive the dynamic valve plate to rotate. According to the key valve core, the opening and closing function of the valve plug can be achieved by changing pressing into rotation, and the problem that a first-use user cannot easily pinpoint an operation direction at once can be avoided; meanwhile, dripping or water running of a water faucet due to the fact that the user does not rotate the valve rod in place out of certain reasons can be avoided; therefore, the key valve core is beneficial to saving water resources.

Description

technical field [0001] The invention relates to a valve core, in particular to a button valve core and a faucet. Background technique [0002] At present, the spools of the existing faucets can be mainly divided into rotary spools and pull-up spools according to the operation mode. Among them, the rotary spool is realized by using a moving valve plate and a static valve plate in cooperation with the valve stem. The opening or closing action of the waterway: turn the valve stem, and the valve stem will drive the moving valve plate to rotate relative to the static valve plate, so that the water holes set on the moving valve plate and the water holes set on the static valve plate overlap up and down or stagger each other, so that Turn water on or off. This kind of rotary valve core in the prior art, when operating, directly turns the valve stem to realize the opening or closing of its waterway. Although the rotation of the valve stem has directionality, it is often not easy fo...

AI Technical Summary

Problems solved by technology

This kind of rotary valve core in the prior art, when operating, directly turns the valve stem to realize the opening or closing of its waterway. Although the rotation of the valve stem has directionality, it is often not easy for first-time users. Find the right direction of rotation; since the rotation of the valve stem has a certain angle range, only when the valve stem is turned in place can the waterway be completely closed during the closing operation. , carelessness, etc.), resulting in failure to turn the valve stem in place, resulting in dripping, running water and other problems in the faucet, which caused a waste of water resources
