Abstract

The invention belongs to the field of water pump equipment, particularly relates to a novel miniature diaphragm pump, and particularly belongs to the field of precision fluid conveying. The novel miniature diaphragm pump comprises a motor, an eccentric wheel is arranged on an output shaft of the motor, the eccentric wheel is sleeved with a shaft sleeve assembly, the shaft sleeve assembly is connected with the middle of a rubber diaphragm, and the center lines of the output shaft, the eccentric wheel, the shaft sleeve assembly and the rubber diaphragm are located in the same direction. The novel miniature diaphragm pump is simple in structure, reliable in work performance, small in size, portable, high in material conveying cleanliness, high in flow adjusting precision, low in noise produced during operation, low in manufacturing cost and more stable in work condition when conveying media.

Description

Technical field [0001] The invention belongs to the field of water pump equipment, and specifically relates to a new type of micro diaphragm pump, and is especially suitable for the field of precision fluid transportation. Background technique [0002] The new type of micro diaphragm pump is a new type of water pump equipment. Because of its high cleanliness and high flow adjustable accuracy, it is gradually widely used in the pharmaceutical and scientific research industries. However, the existing new type of micro diaphragm pump has a complicated structure and high manufacturing cost. For example, I developed a new type of micro diaphragm pump in 2015, which includes a motor, a motor cavity, a motor end cover, an eccentric wheel, a connecting rod, Diaphragm, intermediate plate, valve rubber, connecting plate, buffer cavity and head plate. The output shaft of the motor extends into one end of the motor cavity and is connected to the eccentric. The diaphragm is located between th...
