Adjustable button valve element

Abstract

The invention discloses an adjustable button valve element comprising an upper cover, a shell and a base mounted at the bottom of the shell; a button, a threaded knob, a support frame, a lifting shaft and a shifting structure are sequentially arranged from top to bottom inside the upper cover; the threaded button is sleeved by a gear snap ring, the upper end of the threaded button is clamped in the button, and the lower end of the button supports against and is connected with the gear snap ring; a threaded lifting head is connected to the inside of the threaded button through a screw thread, the threaded lifting head and the upper end of the lifting shaft are clamped into a whole, and the lifting shaft is mounted in a through hole in the center of the support frame; and an upper port of a water outlet channel is covered by a diaphragm, the diaphragm and a pressure relief base are connected into a whole, a water via hole communicating to the water outlet channel is formed in the middle of the pressure relief base, the lower end of the lifting shaft passes through the water via hole and is provided with a snap spring in a snapping way, an O-shaped sealing ring for sealing the lifting shaft is arranged in the water via hole, a clearance slot smaller than the internal diameter of an O-shaped gasket is formed in the lifting shaft, and a water diversion hole communicating to a water inlet hole is formed in the diaphragm.

Description

technical field [0001] The invention relates to the field of bathroom products, in particular to an adjustable button valve core. Background technique [0002] The faucet is an important component in the water supply pipeline. It is used to open and close the waterway and adjust the flow. In order to realize the function of opening and closing the waterway, the existing faucet generally uses a valve core that rotates left and right or up and down. This type of valve core Not only does it need to install a matching handwheel or handle to drive the valve core to open, which leads to an increase in cost, but also the valve core is easy to wear when opening and closing the waterway, which shortens the service life of the valve core. When switching the waterway, the water flow remains constant. , unable to meet the different needs of general users. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an adjus...
