Miniature three-way valve

The invention relates to a miniature three-way valve. Comprising a base provided with a first air outlet, an upper shell provided with a second air outlet and an air inlet, an outer magnet fixed to the inner side of the upper shell, a plug support arranged on the inner side of the outer magnet, a coil fixed to the plug support and a flexible plug fixed to the plug support. And the elastic supporting assembly is connected between the plug bracket and the base or between the plug bracket and the upper shell. And when the coil is electrified, the plug bracket can be driven to move between the first air outlet and the second air outlet, so that one of the first air outlet and the second air outlet is blocked by the flexible plug. The miniature three-way valve has the advantages of being high in driving efficiency, high in magnetic force utilization rate, not prone to being disturbed by an external magnetic field and good in stability. 本发明涉及一种微型三通阀，包括形成有第一出气口的底座、形成有第二出气口和进气口的上壳、固定在上壳内侧的外磁铁、设置在所述外磁铁内侧的堵头支架、固定在堵头支架上
