The invention relates to an all-polymer push-type lotion nozzle and its material preparation method, designed to solve the problem that traditional metal springs are difficult to recycle integrally. The pump core assembly is fastened in the central hole of the large ring; the valve rod of the pump core assembly extends out of the large ring and is connected with the head cap, and a suction pipe is arranged at the water inlet on one side of the pump body. A downward bent everted groove is formed at the top of the valve rod, and evenly distributed air inlet grooves are arranged on the outer wall of the valve rod. One end of the plastic spring abuts against the everted groove, and the other end abuts against the outer ring plane of the inner plug and the end face of the central hole of the large ring. The integrally molded plastic spring consists of an upper sleeve port, a lower sleeve port and a wave-shaped cylinder, sleeved on the outer diameter of the valve rod and integrated with the pump core assembly.
