Pneumatic pump material tank assembly

The invention provides a pneumatic pump material tank assembly. The pneumatic pump material tank assembly comprises an air pump tank support and two air pump tank barrels of the same structure. The air pump tank support is composed of two lantern rings, a connecting piece, a latch operation device and a base. The two air pump tank barrels are clamped in the two lantern rings respectively, the connecting piece is fixed between the two lantern rings, and the latch operation device is fixed between the connecting piece and the base and can rotate relative to the base. A top cover and a bottom cover are installed at the two ends of the air pump tank barrel respectively, an essence feed liquid inlet, a high-pressure gas inlet and an ultrasonic liquid level sensor installation hole are formed in the top cover, an ultrasonic liquid level sensor is installed at the ultrasonic liquid level sensor installation hole, and a one-way valve is arranged at the bottom of the bottom cover.
