Oxygen pump

Abstract

The invention discloses an oxygen pump which comprises an oxygen pump shell, wherein a motor is mounted in the middle of the inner cavity of the air pump shell; two eccentric gears are fixedly connected with the output shaft of the motor; the eccentric gears are rotationally embedded inside round holes in ends of swinging rods; diaphragm chambers are formed in two sides of the air pump shell; diaphragms are in sealed connection with the inner sides of the diaphragm chambers; air inlet one-way valves and air outlet one-way valves are respectively arranged on the outer sides of the diaphragm chambers; the other ends of the swinging rods are connected with the diaphragms; air chambers are formed in the upper sides of the diaphragm chambers; an air guide tube is connected between the two air chambers. The oxygen pump is relatively low in power, low in heating capacity, small in vibration noise and long in service life, a rotation speed of the motor can be changed, the oxygen discharge quantity of the oxygen pump can be freely adjusted, and in addition, due to adoption of two air pumping swinging rods and eccentric gear structures, not only is the air pumping efficiency improved, but also vibration of a single eccentric gear shaft can be balanced.

Description

technical field [0001] The invention belongs to the technical field of oxygen pumps, and in particular relates to an oxygen pump. Background technique [0002] Most of the existing oxygen pumps work with electromagnetic coil components and magnets as the driving power source. The disadvantages are high power, high heat generation, and high vibration and noise; a small part is simply and directly driven by a motor. The disadvantages are small displacement, short life and high noise. Contents of the invention [0003] The object of the present invention is to provide an oxygen pump to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an oxygen pump, including an air pump casing, a motor is installed in the middle of the inner cavity of the air pump casing, and two eccentric wheels are fixedly connected to the output shaft of the motor, and the eccentric The...
