Three-cylinder direct-current miniature pump

Abstract

The invention discloses a three-cylinder direct-current miniature pump which is characterized by comprising a silencing cover (1), an upper cover (2), umbrella heads (3), cylinders (4), a middle cover (5), an eccentric frame (6), a lower cover (7), an eccentric seat assembly (8) and a driving motor (9). The three-cylinder direct-current miniature pump has the advantages that media of the three-cylinder direct-current miniature pump can be pure water or solution with certain acid-base properties, so that service requirements of small household electric appliances and medical equipment can be met; the cylinders of the three-cylinder direct-current miniature pump are in vertical check valve integral designs, are compact in structure and small in size, are integrally formed by dies, and accordingly the integral pump is compact in structure and low in cost; a pump body is thoroughly isolated from the motor by the aid of a totally closed structure, so that the extracted working media are prevented from being in contact with the motor, the liquid cannot seep into the motor to damage the motor, a motor protecting effect is realized, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of micropumps, in particular to a three-cylinder direct current micropump. The micropump is mainly used in medical electronics, health equipment, beauty and body, household appliances, automation equipment, automobile manufacturing and other industries. Background technique [0002] Micropump: Usually, the machines that lift the liquid, transport the liquid or increase the pressure of the liquid, that is, change the mechanical energy of the prime mover into liquid energy to achieve the purpose of pumping the liquid, are collectively referred to as pumps. The general composition of the pump is the driving part + the pump body. There are two ports on the pump body, one inlet and one outlet. The liquid enters from the water inlet and exits from the drain. Any pump that adopts this form and is compact and pocket-sized is called a micro pump. . [0003] At present, the micropumps on the market can only choose p...

AI Technical Summary

Problems solved by technology

[0003] At present, the micropumps on the market can only choose pure water as the working medium, and the solution with a certain acidity and alkalinity will often corrode the pump body, which limits the application of micropumps

There are also micro-pumps with poor sealing between the pump body and the motor, which can easily affect the normal operation of the motor, and are prone to aging, and the impact resistance and elasticity are not satisfactory.
