Pump-valve integration machine for pneumatic waist support of automobile seat

Abstract

The invention relates to a pump-valve integration machine for a pneumatic waist support of an automobile seat. The pump-valve integration machine for the pneumatic waist support of the automobile seatcomprises a gas pump, a pump-valve connecting seat, an electromagnetic gas valve lower base, a normally open electromagnetic gas valve, an electromagnetic gas valve upper cover and a control circuitboard, wherein a one-way gas outlet structure is processed on the pump-valve connecting seat; the one-way gas outlet structure on the pump-valve connecting seat is opposite to and communicate with a gas outlet of the gas pump; the electromagnetic gas valve lower base is fixed onto the gas pump; an installation groove is processed on the bottom part of the electromagnetic gas valve lower base; thepump-valve connecting seat is arranged in the installation groove; a gas passing hole is processed at the position, opposite to the one-way gas outlet structure of the pump-valve connecting seat, on the electromagnetic gas valve lower base; the normally open electromagnetic gas valve is arranged on the electromagnetic gas valve lower base; a gas inlet end of the normally open electromagnetic gas valve corresponds to the gas passing hole of the electromagnetic gas valve lower base; the electromagnetic gas valve upper cover is arranged above the normally open electromagnetic gas valve; and a gasoutlet connector of the electromagnetic gas valve upper cover corresponds to a valve element of the normally open electromagnetic gas valve. The pump-valve integration machine is complete in performances and can be used for simultaneously inflating and deflating multiple gas bags.
