Combined connection type electromagnetic air valve

Abstract

The invention relates to a combined connection type electromagnetic air valve. The combined connection type electromagnetic air valve comprises an air inlet seat, a check valve laterally connected tothe air inlet seat, a valve seat connected to the check valve and an electromagnetic valve body arranged in the valve seat; the combined connection type electromagnetic air valve is characterized in that the air inlet seat is internally provided with an air inlet channel, one end of the air inlet channel is an air inlet connected with an air source, and the other end of the air inlet channel is aseries connection opening for allowing an air inlet of another air inlet seat to be connected in an inserted mode; a complex number of positioning columns and a complex number of inserting connectionterminals are arranged below the exterior of the valve seat, the complex number of inserting connection terminals are electrically connected to the electromagnetic valve body, and the electromagneticair valve can be electrically connected with a circuit board in a inserting mode through the complex number of positioning columns and the complex number of inserting connection terminals; and of themultiple electromagnetic air valves are connected in series through the air inlet seats of the electromagnetic air valves and then communicate with the air source, so that the electromagnetic air valve has the advantages that modular design is achieved, the assembling and maintaining efficiency is improved, and the number of the electromagnetic air valves is expanded according to needs.

Description

technical field [0001] The invention relates to a combined electromagnetic gas valve used in an air bag inflation system, so that a plurality of electromagnetic gas valves can be connected in series, and each electromagnetic gas valve can be easily plugged into a circuit board and connected to a The electrical connection greatly reduces the assembly and maintenance procedures, and the number of electromagnetic valves can be expanded as needed. Background technique [0002] When some car seats, massage seats, massage cushions and massage beds have multiple air bags inside, they will adjust the saturation of the multiple air bags through an air distribution solenoid valve and an air pump to make the air bags fluctuate Changes, thus producing support, massage and other functions for the user. [0003] The existing gas distribution solenoid valve, such as the existing notification number CN103991396B, is to assemble a plurality of solenoid valves and a circuit board in a casing...
