Abstract
An axis moving single air-bag type air pump comprises an air bag, a magnet coil and an E-shaped iron core, wherein a cylindrical magnetic-iron is directly connected on the central position of the air bag to form coaxial connection and the cylindrical magnetic-iron protrudes into a magnetic force gathering circle on the magnet coil, a movable gap is kept between the cylindrical magnetic-iron the magnetic force gathering circle, and the working pressure of the air pump is effectively enhanced.
Description
Technical field
The utility model relates to a kind of air bag type air pump, refers in particular to the air pump of single air bag along the axis back and forth movement.
Background technique
In the prior art, the basic structure of air bag type air pump has two kinds.
First kind of air bag type air pump laterally connects swing arm perpendicular to the air bag axle center in its structure, and it is wide fixing that swing arm one end is done pine, and the other end has a magnet, and the magnet opposite is an electromagnetic coil.When electromagnetic coil is logical electromagnetic coil produces when going up alternating source alternating magnetic field and the magnet polarity generation to-and-fro motion that the same sex is repelled each other, there is a natural attraction between the sexes, drive air bag by swing arm and do the tidal air work of stretched and relaxed ground, then by two Air Valve Control air-flow one-way flows in the other direction in the air pump core, output gas flow.The air pump of this structure has structurally determined a kind of defective: air pump pressure can not improve, and can only maintain below the 0.02MPa.Why such structural pressure can not improve? problem is, the active force of the alternating magnetic field that magnet in the swing arm and electromagnetic coil produce is the elasticity coupling, swing arm does not always catch up with the alternating magnetic field variation merit is handled properly, therefore, the dynamics that is added on the air bag by swing arm is restricted, and the stream pressure of air pump is just carried to be come up like this.
The air bag type air pump of second kind of structure, done improvement though will have the swing arm of magnet and the structural relation of electromagnetic coil, the swing arm that has magnet is done the shuttle type to-and-fro motion along magnetic line of force action direction between two electromagnetic coils, the air bag that drives two ends is done the tidal air motion, but do not break away from the elasticity coupled modes of magnet and action of alternating magnetic field power, the air pump working pressure still is difficult to be significantly improved.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that the coupled modes of existing air bag type air pump magnet and action of alternating magnetic field power cause, and a kind of axial-movement single air bag type air pump is provided, and can promote the working pressure of air pump effectively.
For achieving the above object, the solution that the utility model is taked is: a kind of axial-movement single air bag type air pump, it comprises air bag, electromagnetic coil and E shape iron core, cylinder-shaped magnet directly is connected the air bag central position and forms coaxial connection, cylinder-shaped magnet puts in the magnetic force that is arranged on the electromagnetic coil to be assembled in the circle, and cylinder-shaped magnet and magnetic force are assembled circle and left the free gap between the two.
When electromagnetic coil is logical when going up alternating source, the alternating magnetic field that is produced is gathered magnetic force to be assembled around the circle, alternating magnetic field change in polarity and cylinder-shaped magnet polar orientation are on same axis, under the same sex is repelled each other the effect that there is a natural attraction between the sexes, cylinder-shaped magnet is done the piston type motion in magnetic force is assembled circle, drive air bag and do tidal air work.
The alternating magnetic field that produces when electromagnetic coil connects alternating source alternately forms opposite polarity (S, the N utmost point) E shape iron core 7 and is pooled to holding on the same axis at two ends, and fully envelope cylinder-shaped magnet, produce " outstanding magnetic effect ", and make cylinder-shaped magnet do the work of piston motion drive air bag.Like this, directly drive the cylinder-shaped magnet of air bag work and the active force of alternating magnetic field and can be in the rigidity couple state, promoted cylinder-shaped magnet and alternating magnetic field interaction force between the two, so the stream pressure of air bag is improved fully, can reach more than the 0.03MPa, promote the working pressure of air pump effectively.
