Abstract
An all-plastic pump comprising an outer cover, a plastic spring, an inner cover and a pressing head. The pump includes an accessory cavity in the outer cover, with a conveying hole. A tubular plastic spring is positioned within the cavity, surrounding the conveying hole. Supporting rods are arranged circumferentially on an inner wall of the plastic spring's port, with one end of the rods connected to a baffle. The inner cover surrounds the plastic spring, and a stop tube is inserted through the supporting rods, with its port sealing against the baffle. The pressing head, mounted in a pressable manner, includes a discharging hole, pressing sheet, and conveying tube. When pressed, the pressing sheet compresses the plastic spring, causing separation between the baffle and stop tube, allowing fluid discharge.
