Liquid pumping apparatus

Abstract

A liquid pumping apparatus is provided, including a pump head, a liquid charging gun, and a tube part. A tube passes through the gun and connects to the gun head. A holding part and body part form a hollow structure. The gun includes a battery compartment, anti-slip structure, and spring reset switch, and cooperates with a PCB and operation panel for on-off control. The tube is segmented with anti-slip ribs, hanging spaces, and a bent part, and can engage an oil filling port for hands-free use. The liquid channel cross section is designed to improve flowability. The pump head is a detachable housing with a motor and impeller. Components are sealed by sealing rings and silicone plugs. The apparatus is compact, anti-slip, easy to operate, reliable in sealing, low maintenance, improves space utilization and reduces volume, and is suitable for various liquid delivery scenarios with high efficiency and stability.
