Problems solved by technology
The defect of the existing aeration pump is that: due to the dislocation assembly of the pole surface of the magnetic pole magnetic field generated by the current and the magnetic pole magnetic field pole surface of the permanent magnet, that is, only part of the magnetic field of the two pole surfaces generates mutual repulsion and attraction, so the generated magnetic drive The force is small; in addition, the force arm of the magnetic drive is larger than the force arm of the cup, resulting in a short stroke of the intake and exhaust, and a small displacement of the pump.

Embodiment Construction
[0017] The above is the basic structure and working principle of the double-body permanent magnet half-wave oxygenation pump, attached Figure 4 And Figure 5 A schematic diagram showing the structure and working principle of a single-body permanent magnet half-wave oxygenation pump. The basic feature of the single-body permanent magnet half-wave oxygenation pump is that the iron core 2 is "U"-shaped, and the coil winding 3 is wound on the iron core 2. The two permanent magnets 4 respectively correspond to the magnetic poles of the iron core 2 and are fixedly assembled on the cup 7. The side of the two permanent magnets 4 facing the iron core 2 is the opposite polarity magnetic pole; the magnetic pole properties of the two permanent magnets 4 and the current of the coil 3 The properties of the magnetic poles generated on the iron core 2 are correspondingly the same; the permanent magnet 4 is directly connected to the cup 7 on the pump body 6 through the connecting piece 5b. Its...

The invention provides a permanent magnet half-wave aeration pump whose driving principle is designed based on mutual repulsive force which is generated between a pulsating magnetic pole magnetic field induced on a coil core 2 and an invariable magnetic pole magnetic field of a permanent magnet 4 when a coil winding 3 is connected to a half-wave single-phase AC power supply and the property that apermanent magnet has ferromagnetic attraction. The basic characteristics of the permanent magnet half-wave aeration pump are as follows: the pole face of the permanent magnet 4 corresponds to the pole face of the coil core 2; the direction of the force that drives the air pump to inhale and compress the exhaust gas is parallel to the normal direction of the magnetic line of force of the magneticpole; the permanent magnet 4 is connected linearly with a cup 7 of the air pump; and the core 2 is fixedly mounted on a coil former 3a. Since a diode is serially connected to the coil winding 3 of thepermanent magnet half-wave aeration pump, the suction stroke of the pump is generated by the attraction of the permanent magnet 4 to the coil core 2, so the pump has a better energy-saving effect; since the permanent magnet 4 is directly connected to the cup 7, the stroke of the cup 7 is long and the amount of exhaust of the pump is large.
Description
Technical field [0001] The invention relates to the field of oxygen increasing pumps, in particular to a single pump body or a double pump body permanent magnet half-wave oxygen increasing pump. Background technique [0002] The single-phase AC aeration pumps currently in use are generally divided into single-body aeration pumps and double-body aeration pumps; in terms of air output, they are generally divided into two gears, and the high-end is connected to a single-phase AC full-wave power supply. The low gear is a half-wave power supply connected by a diode in series with the coil. The driving principle of the two different pump bodies is the same, and the power source is the interaction between the magnetic field of the permanent magnet and the magnetic field generated by the single-phase alternating current. One of the characteristics is that the pole faces of the permanent magnets and the pole faces of the magnetic field generated by the current are arranged in a dislocati...
