摘要： A piston is formed by an outer edge of the cap. The piston and an inner wall of the nozzle body form a dynamic seal for the air cylinder, so that a main body of the air pump is formed. The cap extends downwardly to form a hydraulic cylinder. The hollow compression rod connects a pump component of the hydraulic cylinder and the mixing chamber of the head, so that a main body of the liquid pump is formed. The hollow compression rod is provided with an upper disk. The upper end of the upper disk passes the air outlet of the nozzle body and is inserted into the connecting pipe of the head in snap fit, and the upper disk opens or closes the air outlet. A fastening position is designed to form a gap between the head and the nozzle body to realize a floating valve function at the head.
