Abstract
The utility model discloses a mini-size electric pump comprising a motor, an impeller, and a pump body housing. The mini-size electric pump is characterized in that a magnetic loop fixing sheet and a driving magnetic loop are sheathed on a motor shaft, a driven magnetic loop is arranged in the impeller, and a driven shaft connected with the pump body housing is arranged in the driven magnetic loop. The bottom of the impeller is in an arc shape, and the driving magnetic loop and the driven magnetic loop are isolated from each other by the inner cover of the pump body. The utility model utilizes the magnetic force to transfer the rotation to eliminate a lubricating chamber, so that the mini-size electric pump has the advantages of simple structure and easy maintenance.
Description
The utility model relates to a kind of micro electric pump.
Existing micro electric pump is that water pump and motor coaxial combination are integral, and its transmission shaft, the pump housing, pump case, impeller all are metalworks, easily produces wearing and tearing during work, therefore, the grease chamber also will be set for lubricated, and this makes existing micro electric pump structure become with complexity.
The utility model aims to provide a kind of simple in structure, micro electric pump that frictional force is little.
The micro electric pump that the utility model proposes contains motor, impeller, pump housing shell, it is characterized in that motor shaft is provided with magnet ring fixed plate and active magnet ring, driven magnet ring is housed in the water pump vane, being point-like with pump housing inner cover contacts, water pump vane is positioned on the driven shaft of pump shell, and can rotate around driven shaft, pump housing inner cover is with initiatively magnet ring and driven magnet ring are isolated.When driven by motor active magnet ring rotated, because of the effect of magnetic force, driven magnet ring also rotated thereupon, thereby drove the water pump vane rotation, thereby made the micro pump that the utility model proposes have the function of drawing water.
Because the utility model utilization initiatively rotation of magnet ring drives driven magnet ring and rotates, this just structure of utilizing the magnetic force transmission to rotate has saved the fuel feeding chamber that provides lubricated, makes that the micro electric pump that the utility model proposes is simple in structure, and is compact, just with maintenance.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the utility model embodiment's a structural representation.
Among the figure, the 1st, motor, the 2nd, pump bracket body, the 3rd, copper sheathing, the 4th, magnet ring fixed plate, the 5th, plus screw, the 6th, active magnet ring, the 7th, water pump fixing frame, the 8th, pump housing inner cover, the 9th, seal ring, the 10th, pump housing shell, the 11st, driven magnet ring, the 12nd, water pump vane, the 13rd, driven shaft.
With reference to accompanying drawing, motor 1 is fixed on the pump bracket body 2, pump bracket body 2 links with pump housing shell 10, copper sheathing 3 and motor shaft, magnet ring fixed plate 4 has cooperated gearing, the water pump fixing frame is used for fixing water pump, pump housing inner cover 8 is not made by there being the magnetic material of suction, it is as the hemisphere type apical axis supporting of water pump vane 12 bottoms, seal ring 9 seals, and pump housing shell 10 can adopt working of plastics, in the driven shaft 13 that is connected with impeller 12 is housed, driven magnet ring 11 is housed in the impeller 12, the hemisphere type apical axis of impeller 12 bottoms is point-like with pump housing inner cover and contacts, and with reference to accompanying drawing, can make the micro electric pump that the utility model proposes with plus screw 5 fastening above-mentioned each parts.
