For convenience of description, herein, the front refers to the direction of liquid conveyance, i.e., the left side in fig. 1; the rear is opposite the front, i.e. to the right in fig. 1.
Referring to fig. 1-3, the present invention provides a high efficiency electromagnetic pump, which includes a pump head 1 and a pump body 2 connected in front and back, a coil support 3 surrounding the outside of the pump body, a coil 4 wound on the coil support, and a protective casing 5 surrounding the coil support and the coil; a first cavity 2.1 is arranged in the pump body 2, a liquid inlet 2.2 communicated with the first cavity is arranged at the rear end of the pump body, a piston 6 is arranged in the first cavity in a sliding manner, and a flow passage 6.1 penetrating through the front and the rear of the piston is arranged in the piston; a second cavity 1.1 is arranged in the pump head 1, the front end of the piston 6 extends into the second cavity, and a first one-way cone valve 7 is arranged in the second cavity; the piston 6 comprises a piston main body 6.2 made of non-magnetic material and a permanent magnet assembly 6.3 surrounding the piston main body; the permanent magnet assembly comprises two cylindrical permanent magnets 6.3a which are opposite in the same pole, and an iron connecting ring 6.3b connected between the two permanent magnets.
Because the two permanent magnets 6.3a in the permanent magnet assembly 6.3 are opposite in homopolar (opposite in S pole or opposite in N pole) and are connected into a whole by the iron connecting ring 6.1b, the magnetic resistance of the iron connecting ring is small, the magnetic induction lines at the opposite ends of the two permanent magnets can be concentrated in the iron connecting ring (namely, the magnetic field at the position is shielded), so that the external magnetic field of the whole permanent magnet assembly appears to be stronger in one polarity and weaker in the other polarity (namely, the permanent magnet assembly shows single polarity in general), thus, the permanent magnet assembly is moved in one direction when the current in the coil 4 is positive, in the other direction when the current in the coil is negative, therefore, the reciprocating motion of the piston can be realized by directly introducing commercial power into the coil without arranging a filter circuit, the complexity of the circuit structure is reduced, and the energy consumption and the heat productivity are also reduced.
Taking fig. 3 as an example, the two permanent magnets 6.3a are opposite to each other in terms of N poles, and the single polarity appearing in the entire permanent magnet assembly is S polarity, and when the front end of the coil 4 is N pole and the rear end is S pole, the piston 6 moves forward, and when the front end of the coil 4 is S pole and the rear end is N pole, the piston 6 moves backward.
Here, the material of the piston body 6.2 may be, but is not limited to, plastic, ceramic, etc. The iron connection ring 6.3b can be replaced by a connection ring made of other high magnetic permeability material.

The iron connecting ring 6.3b covers the end part of the permanent magnet 6.3a, so that the shielding effect on a magnetic field can be further improved, the unipolar property of the permanent magnet assembly is further improved, and the driving force is further improved.
Further, as shown in fig. 2, an annular mounting groove 6.2a is formed on the circumferential surface of the piston main body 6.2, the permanent magnet assembly 6.3 is disposed in the mounting groove 6.2a, and the outer diameter D of the permanent magnet assembly is smaller than the outer diameter D of the piston main body. In this way, the piston main body 6.2 is connected with the first cavity 2.1 in a sliding and sealing manner, and the permanent magnet assembly 6.3 does not rub against the cavity wall of the first cavity 2.1, so that the smoothness of sliding is not affected.
Preferably, as shown in fig. 1, a buffer spring 8 may be disposed at each of the front and rear ends of the first cavity 2.1. The impact between the piston 6 and the pump body 2 is reduced by the buffer spring 8, thereby reducing vibration and noise.
