Problems solved by technology

[0002] The air pump is usually composed of a vacuum diaphragm valve and a reed valve. By introducing fresh air into the existing air pump, most of them are in single suction and exhaust mode, that is, the drive motor shaft rotates one revolution, and the air pump performs one suction and exhaust. Such a structure makes the air pump work inefficient and the exhaust flow is small

Abstract

The invention discloses a four-piston air pump which has four suctions and four exhausts by rotating a motor for one cycle. The air pump comprises four cover plates, four air guide plates, a power assembly, a pump body, and a plurality of diaphragms for suction and exhaust. The power assembly is mounted in a motor mounting hole in the pump body, the four air guide plates are respectively attachedand assembled on four mounting surfaces of the pump body, and the four cover plates are respectively attached and assembled to the four air guide plates. During the process that the motor shaft rotates for one cycle, two transverse pump films perform one suction and one exhaust respectively, and two longitudinal pump films perform one suction and one exhaust respectively, Therefore, the pump has four suctions and four exhausts when the motor shaft rotates for one cycle. The common pump has only one suction and one exhaust when the motor shaft rotates for one cycle. The invention has the characteristics of high efficiency, larger exhaust flow amount, and the like.

Description

technical field [0001] The invention relates to an air pump which has four times of air suction and four times of exhaust when a motor rotates once. Background technique [0002] The air pump is usually composed of a vacuum diaphragm valve and a reed valve. By introducing fresh air into the existing air pump, most of them are in single suction and discharge mode, that is, the drive motor shaft rotates one revolution, and the air pump performs one suction and exhaust. Such a structure makes the working efficiency of the air pump low, and the exhaust flow rate is small. Contents of the invention [0003] The purpose of the present invention is to provide a four-piston air pump with four times of air suction and four times of exhaust after the motor rotates once. Two pump membrane supports with different axial directions are connected, and the two-axis movement mode under the condition of motor driving realizes the motor rotates one revolution, with four times of suction and...
