Abstract: An all-plastic external foam pump, including an actuator, a fixing member, a plunger, an elastic member, a cylinder body, and a straw, is provided. One end of the fixing member is fixed or detachably connected to the actuator, and the other end is fixed or detachably connected to the plunger. The fixing member is at least partially accommodated in the cylinder body. One end of the plunger is penetrated into the elastic member. The straw is installed on one end of the cylinder body. A pulling rod is disposed in the plunger. The pulling rod is disposed in linkage with the plunger. The elastic member is made of a recyclable elastic material. A liquid mixing portion is disposed in the fixing member.

Abstract: A spray pump comprising a small piston and an upper pump rod with a liquid accumulation cavity is provided. The upper pump rod is provided with a liquid discharge hole communicates with the liquid accumulation cavity, and the small piston is provided with a sealing column for sealing the liquid discharge hole. A central column is provided with an ejector rod extending into the liquid discharge hole, and a liquid flow gap is disposed between the ejector rod and the liquid discharge hole. A central hole communicates with the liquid discharge hole is disposed at a central part of the central column, and a press head with a lower part being fixed with the central column. A press plate is fixed with the upper pump rod, and a press gap is disposed between an upper side of the press plate and a lower side of the press head.

Abstract: A single-hand pressed foam pump head comprises a pump filled with foam liquid or emulsion. A spring is provided inside the pump. The pump comprises a press head and a fixed outflow cap; the fixed outflow cap is provided with a vertical connecting tube and is connected to a connecting end of a bottle; the connecting tube has a foam or liquid channel. A top portion of the connecting tube is provided with a horizontal connecting channel. The horizontal connecting channel is connected to a vertical plugged-in tube. When the connecting tube is pressed downward such that the vertical plugged-in tube is inserted into an outflow chamber of the fixed outflow cap, the connecting tube and the outflow chamber are connected to each other to form a top outflow channel. The present invention is simple in structure, stable in function and convenient for people to use.
