Abstract
The invention relates to a foam pump, which is used to absorb liquid in a container and make the liquid spray out foam from a nozzle. The shell is composed of a pressure head, a screw cap and a cylinder. The shell includes a pressure head, an air valve, a main column, Large piston, screw cap, connecting rod, small piston, cylinder, spring and valve. There is a network pipe between the pressure head and the air valve, and the spring is provided between the main column and the base of the cylinder. Among them: a network pipe extends into the pressure head sleeve from below Inside, the lower end of the network pipe communicates with the air valve, and at least a filter screen is provided at the entrance of the network pipe; the air valve is a tubular structure, and the middle part is provided with a circular ring with a downward peripheral edge and a convex edge, and the pressure head is against the top of the circular ring. An air inlet groove is arranged on the inner wall of the ring, and an exhaust groove is arranged on the inner wall of the tube below the air valve. Because the spring is placed in the air chamber of the cylinder, it prevents it from contacting with chemical materials and prevents the spring from rusting; and because the large and small pistons can be unlinked, it provides sealing, and the design of the network tube makes the sprayed foam more uniform.
Description
Technical field [0001] The invention involves a foam pump. Background technique [0002] The existing foam pump is composed of the export -connected vapor cylinder and the solution cylinder. Among them, the pumping cylinder is composed of the cylinder body and the piston.The piston is connected. When using the pressure head, press the piston piston in the pumping cylinder synchronously with the piston of the pumping cylinder.The mixing becomes a bubble, but this constitution is high. [0003] In addition, the patent number ZL2005200636954 revealed another type of foam pump, including the cylinder body, head, plug tube, and spring.The center and cylinder are located on the periphery of the liquid cylinder. The cylinder is matched with the ring wing of the lower head.The liquid inlet of the lower part of the section and the liquid cylinder constitutes the inlet valve inlet. The lower part of the limited pillar is provided with inverted hooks to hook the inlet of the inlet.The liqui...
