Abstract

The invention discloses a full-plastic foam pump. The pump comprises a press head, a net connection, a thread, a large piston, a connecting rod, a valve, an elastomer, a secondary column, a small piston, a piston seat, a ball and a body, a gas-liquid flow guiding device comprises a gas-liquid mixing cavity arranged on a top plate of a seat body, a flow guiding column located in the gas-liquid mixing cavity and connected with the top plate, and a plurality of gas-liquid mixing holes arranged around the flow guiding column and in the top plate, wherein a gas flow guiding groove is formed in thelower end of the gas-liquid mixing cavity; the flow guiding column extends into a connecting pipe, a gap is formed between the flow guiding column and the connecting pipe, and the lower end of the gas-liquid mixing cavity is attached to a partition plate between an upper cavity and a lower cavity. Due to adoption of the structure, airflow surrounds a liquid flow, then pressurizing and diffusing are conducted, no vortex is generated, the atomization performance is improved, and the flow speed is accelerated.
