Disclosed is an electromagnetic vibratory pump, comprising a first C-shaped winding and a first magnet. The first C-shaped winding comprises a first coil and a first electromagnetizable member. The first coil covers the first electromagnetizable member, which comprises a first main body, a first leg and a second leg. The legs are connected to the first main body, and the distance between the legs is reduced from a first width to a second width from the first main body. The first magnet swings in a circular tangential direction. A point of tangency of the circular tangential direction is configured apart from the first leg and the second leg respectively by a first minimum distance. The first minimum distance is less than a half of the second width. The first magnet is driven by the first magnetic line of force to move in the first circular tangential direction, and the first magnet is driven by the second magnetic line of force to move in the second circular tangential direction. |

1. An electromagnetic vibratory pump, comprising:
a first C-shaped winding including a first coil and a first electromagnetizable member, the first coil covering the first electromagnetizable member, the first electromagnetizable member including a first main body, a first leg and a second leg, the first leg and the second leg individually including a first end, a second end and a magnetizable portion between the first end and the second end, the first end of the first leg and the first end of the second leg being connected with the first main body, wherein the magnetizable portion of the first leg and the magnetizable portion of the second leg define a first width therebewteen, the second end of the first leg and the second end of the second leg define a second width therebewteen, and the second width is less than the first width; and a first magnet arranged in proximity to the second end of the first leg and the second end of the second leg, the first magnet swinging in a circular tangential direction, wherein a first minimum distance is defined between a point of tangency of the circular tangential direction and each second end, and the first minimum distance is less than a half of the second width; wherein the first C-shaped winding, in the presence of electric current, forms a first magnetic line of force and a second magnetic line of force which are of different directions, the first magnet being driven by the first magnetic line of force to move in a first circular tangential direction and the first magnet being driven by the second magnetic line of force to move in a second circular tangential direction; and wherein the following formula is satisfied:
0.5×w<(w1+w″)<1.5×w or0.5×w<(w″+w2)<1.5×w wherein w represents a width of the first magnet, w1 represents an end face width of the second end of the first leg, w″ represents the second width, and w2 represents an end face width of the second end of the second leg. |
