Abstract: The disclosure discloses an all-plastic pump including an outer cover, a plastic spring, an inner cover and a pressing head. An accessory cavity is defined in the outer cover, and a conveying hole is formed inside the accessory cavity. The plastic spring surrounds the conveying hole, a plurality of supporting rods are circumferentially disposed on an inner wall of the plastic spring, and the plurality of supporting rods are connected to a baffle. The inner cover surrounds the plastic spring, a stop tube is disposed inside the inner cover, penetrates into a space defined by the supporting rods, and is in sealing abutting connection with the baffle. The pressing head is installed in the accessory cavity in a pressable manner, and provided with a discharging hole, a pressing sheet and a conveying pipe. The pressing sheet is opposite to an end face of the plastic spring, the conveying tube is inserted into the stop tube, the conveying tube is in connection and communication with the discharging hole, and pressing of the pressing head is configured to push the pressing sheet to urge the plastic spring so as to separate the baffle and the stop tube from each other. Therefore, through the solution, a pump head can still be opened and closed, a metal spring is replaced with the plastic spring, and the problem that an existing pump head is inconvenient to directly recycle is practically solved.
