Abstract

The invention relates to the technical field of mini air pumps, in particular to a flat annular mini air pump of a small sphygmomanometer. The flat annular mini air pump comprises a motor, a connecting plate, a first annular body and a second annular body. The motor is connected with the connecting plate, and the connecting plate is connected with the first annular body and the second annular body. The integral structure of the mini air pump is flat, and usage and storage of an ultra-thin arm type electronic sphygmomanometer are facilitated. Two sets of cylinders can be finish pressurizing through one-circle rotation of the motor, the pressurizing amount is large, and the pressurizing speed is high.

Description

technical field [0001] The invention relates to the technical field of micro air pumps, in particular to a flat annular micro air pump for a small sphygmomanometer. Background technique [0002] Micro air pump refers to a gas conveying device with small size and gaseous working medium, which is mainly used for gas sampling, gas circulation, vacuum adsorption, vacuum pressure maintaining, pumping, pumping, pressurizing and other purposes. [0003] Micro air pumps are divided into micro negative pressure pumps, micro vacuum pumps, micro gas circulation pumps, micro air pumps, micro gas sampling pumps, micro air pumps, micro air pumps, micro air pumps, etc. according to their working principles. There are diaphragm type, electromagnetic type, impeller type, piston type and so on. Micro air pumps widely used in general medical and health, scientific research, laboratories, environmental protection, instrumentation, chemical and other industries mainly refer to micro vacuum pump...
