Handle Control Construction for Electronic Water Faucets

Abstract

The invention provides a handle control structure used for an electronic faucet. The handle control structure used for the electronic faucet comprises a control handle assembly, a switch device and a triggering element. The control handle assembly is installed on a faucet body of the electronic faucet and comprises a valve assembly and a handle for controlling the valve assembly. The switch device comprises a signal sending element and an excitement element which are installed on the valve assembly. When the excitement element is triggered to get close to or far away from the signal sending element, the signal sending element is promoted to send a first signal or a second signal so that an electromagnetic valve can be closed or opened and mixed water can be prevented from flowing through the electromagnetic valve or permitted to flow through the electromagnetic valve. The triggering element can act synchronously along with the operation of the handle. When the handle is in any temperature adjustment position of a closed position or an opening position, the triggering element can trigger or leave the excitement element to trigger or close the switch device. In this way, water can be controlled to come out through the opening and closing operation of the handle, operation and control have no dead angle, the operation stability and assembly yield are high, and the handle control structure used for the electronic faucet is particularly suitable for a control handle assembly of a ceramic valve element or a stainless steel valve element.

Description

technical field [0001] The invention relates to a faucet, in particular to an electronic faucet which can simultaneously control the mixing ratio of cold and hot water and switch water by operating a handle. Background technique [0002] As we all know, the control handle of the traditional single-handle faucet usually adopts a typical ceramic valve core or stainless steel valve core, that is, there is a ceramic chip or stainless steel chip inside the valve core that can be rotated relatively to adjust the mixing flow. 、Turn the handle outward to control the water outlet and adjust the flow. For example, when you pull the handle outward, you can open and increase the water flow, and when you pull it back inward, you can close or reduce the water flow. In addition, when the handle is turned left or right, the output of cold water or hot water can be controlled, or the mixing ratio of cold water and hot water can be controlled to adjust the outlet water temperature. The new p...

Problems solved by technology

However, the existing typical ceramic spool or stainless steel spool can control the spindle switch no matter the handle is in any temperature adjustment position, that is, no matter it is in cold water, hot water or any mixing position of cold and hot water mixing ratio, However, the above-mentioned U.S. patent adopts a traditional ball valve structure, so that the magnet assembly can trigger the sensing assembly to close the solenoid valve only when the handle is in a specific position. Obviously, its control structure is not suitable for the existing ceramic valve core or stainless steel valve core. The structure of the spool
