Title:
SOLENOID VALVE AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/246538
Kind Code:
A1
Abstract:
The present application relates to the field of valves, and in particular to a solenoid valve and an apparatus. The solenoid valve comprises: a valve body, which has an accommodating cavity; a magnetic yoke, which is arranged in the accommodating cavity and has a mounting groove; a coil winding, which is arranged in the mounting groove; a valve core assembly, which is arranged in the accommodating cavity and comprises a moving coil winding; and a multi-stable element, an outer peripheral end of the multi-stable element being connected to the valve body, an inner peripheral end of the multi-stable element being connected to the valve core assembly, and the multi-stable element being provided with at least a steady-state site for positioning the valve core assembly. When the coil winding is powered on, the magnetic yoke can attract the valve core assembly, and the valve core assembly drives the multi-stable element to deform to the steady-state site, such that the valve core assembly blocks or unblocks a gas path of the solenoid valve; and when the valve core assembly moves, the moving coil winding can generate a magnetic field, and the magnetic field generated by the moving coil winding can interact with a magnetic field generated by the coil winding, so as to detect a signal change of the coil winding.
