Embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See shown in Figure 1ly, present embodiment comprises: the pump housing 1, electromagnetic coil module 2, plunger 3, Returnning spring 4 and buffering spring 5, wherein; Electromagnetic coil module 2 is installed in the pump housing 1 outside; Magnetic core plunger 3 is installed in the pump housing 1 inside, and Returnning spring 4 is arranged in the pump housing 1, and Returnning spring 4 acts on the plunger 3; It is in the opposite direction that Returnning spring 4 acts on the electromagnetic force that elastic force direction and electromagnetic coil module 2 on the plunger 3 act on the plunger 3; Damping spring 5 is arranged in the pump housing 1, carries out in the stroke of compression reseting spring 4 at plunger 3, and 5 pairs of plungers 3 of damping spring apply and Returnning spring 4 elastic force in the same way.
Particularly:
The above-mentioned pump housing 1 comprises: sleeve pipe 11, the intake pipe 12 that is positioned at sleeve pipe 11 two ends and outlet pipe 13.Wherein in sleeve pipe 11, constitute the cavity 10 that supplies plunger 3 operations.Intake pipe 12 is one-body molded with sleeve pipe 11, and outlet pipe 13 is to be fixed together after forming respectively with sleeve pipe 11.Be provided with end cover 8 in the junction of sleeve pipe 11 and outlet pipe 13.This end cover 8 adopts the hollow setting, and cavity 10 is communicated with outlet pipe 13.Be provided with a safety check 9 in the outlet pipe 13.The spring one-way cock structure that this safety check 9 adopts, it comprises valve head 91 and spring 92, valve head is resisted against the outlet of end cover 8 under spring action, will hold cover 8 sealings, prevents that the water that pumps is back in the cavity 10.
End near intake pipe 12 in cavity 10 is provided with positioning pipe 6, and the end of this positioning pipe 6 is formed with flange 61.Described Returnning spring 4 one ends are set in positioning pipe 6 outsides; And be pressed on flange 61 places; Its other end is pressed on the end face of plunger 3, has the trend to end cover 8 direction operations to make plunger, and under electromagnetic coil module 2 off positions; Plunger 3 keeps being pressed on the end cover 8, promptly is arranged in the high order end of stroke under plunger 3 normalities.
Described damping spring 5 is positioned at positioning pipe 6, and the one of which end is limited at flange 61 places of positioning pipe 6, and another can be compressed end towards plunger 3.When the right operation of plunger 3 to left-hand, at first need overcome the elastic force of Returnning spring 4, behind the operation certain distance, plunger 3 will contact with damping spring 5, utilize the elastic force of damping spring 5 to absorb the kinetic energy of plunger 3, to play cushioning effect.Simultaneously, damping spring 5 will increase the resistance of the right operation of plunger 3 to left-hand, can effectively shorten the stroke of plunger 3, thereby the water yield that causes the utility model to suck, spray reduces, and regulate the utility model pump water yield thereby play.
During work, when electromagnetic coil module 2 generation half-wave frequency conversion magnetic fields, i.e. the magnetic force of electromagnetic coil module 2 generations is the magnetic force in the same way of interval interrupt.This magnetic force will promote as the right operation of plunger 3 to the left-hand of magnetic core.At this moment, along with the operation of plunger 3, cavity 10 spaces that are positioned at plunger 3 right sides will be compressed, and the hydraulic pressure in this space increases, and current will be washed one-way valve 32 open, enter into the right side through intake tunnel 30.Along with the operation of plunger 3, plunger 3 is with receive the resistance of Returnning spring 4 with buffering spring 5 simultaneously, and plunger 3 operation strokes will shorten.When the magnetic force of electromagnetic coil module 2 interrupts, plunger 3 will reset rapidly under Returnning spring 4 effects (promptly to the operation of a dextrad left side), and the water that be inhaled in the intake tunnel 30 this moment will be pushed safety check 9 open, and simultaneously the water pump in the outlet pipe 13 gone out.The operation of pump water is accomplished in operation so repeatedly.Certainly, when using first, owing to also do not suck water in the whole pump housing 1; So what begin to pump most only is air, after the air in the pump housing 1 pumped fully, current just were pumped out; Since air pump principle and above-mentioned water to pump principle identical, give unnecessary details no longer one by one here.
Certainly; The above is merely the specific embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
