Abstract
The invention discloses a kind of oxygen pumps, including air pump shell, motor is installed in the middle part of the inner cavity of the air pump shell, two eccentric wheels are fixedly connected on the output shaft of the motor, the eccentric wheel rotation is socketed in the circular hole of swing rod one end, the both sides of the air pump shell are equipped with chamber of septum, the inner seal of the chamber of septum connects diaphragm, it is respectively equipped with breather check valve and outgassing nonreturn valve on the outside of the chamber of septum, the other end of the swing rod is connected on diaphragm, the upside of the chamber of septum is equipped with gas chamber, and gas-guide tube is connected between the gas chamber.The oxygen pump power is less, calorific value is low, vibrating noise is small, long lifespan, change the rotating speed of motor, oxygen can be made to pump the freely regulated feature of capacity, and set swing rod and eccentric wheel structure there are two pump gas, pump gas efficiency is not only improved, but also the vibration that single eccentric wheel shaft generates can be balanced.
Description
Technical field
The invention belongs to oxygen pump technical fields, and in particular to a kind of oxygen pump.
Background technology
Existing oxygen pump, most of is all that electromagnetic coil assembly cooperation magnetite works as driving power source, disadvantage
It is that power is larger, calorific value is big, vibrating noise is big；Fraction be simply directly driven with motor tympanites work, the disadvantage is that
Capacity is small, short life, noise are big.
Invention content
The purpose of the present invention is to provide a kind of oxygen pumps, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides the following technical solutions：A kind of oxygen pump, including air pump shell, the air pump
Motor is installed in the middle part of the inner cavity of shell, two eccentric wheels, the eccentric wheel turning set are fixedly connected on the output shaft of the motor
It being connected in the circular hole of swing rod one end, the both sides of the air pump shell are equipped with chamber of septum, and the inner seal of the chamber of septum connects diaphragm,
Breather check valve and outgassing nonreturn valve are respectively equipped on the outside of the chamber of septum, the other end of the swing rod is connected on diaphragm,
The upside of the chamber of septum is equipped with gas chamber, and gas-guide tube is connected between the gas chamber.
Preferably, the end of the motor is socketed in bearing, and bearing is fixed on by bearing block in air pump shell.
Preferably, the outlet side of the outgassing nonreturn valve is arranged in gas chamber.
Preferably, the swing rod and eccentric wheel are disposed as one or at least three.
The technique effect and advantage of the present invention：The oxygen pump power is less, calorific value is low, vibrating noise is small, long lifespan, changes
The rotating speed for becoming motor can make oxygen pump the freely regulated feature of capacity, and set the swing rod and eccentric wheel knot there are two pump gas
Structure not only improves pump gas efficiency, but also can balance the vibration that single eccentric wheel shaft generates.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
